How does a rolling machine work?
What are the classifications of rolling machines?
How to maintain the rolling machine?
The upper roller of the symmetrical rolling machine is at the symmetrical position of the center of the two lower rollers. The hydraulic oil in the hydraulic cylinder acts on the piston to make vertical lifting movement. The plastic metal sheet with flat specification passes between the three work rolls (two lower rolls and one upper roll) of the rolling machine. With the help of the lower pressure of the upper roll and the rotational movement of the lower roll, the metal plate is continuously processed through multiple passes. Bending (the inner layer is compressed and deformed, the middle layer is unchanged, and the outer layer is stretched and deformed), resulting in permanent plastic deformation, and rolled into the required cylinder, cone or part of them.
Rolling machines have different types depending on the field of use. According to the number of rolls, it is divided into three-roller and four-roller. The three-roller is divided into a symmetrical three-roller plate rolling machine, a horizontal-down three-roll plate-rolling machine, an arc-down-type plate-rolling machine, an upper-roll universal three-roll plate rolling machine, and a hydraulic CNC plate rolling machine. From the transmission, it is divided into mechanical type and hydraulic type. In terms of the development of the plate rolling machine, the upper roll universal type is the most backward, the horizontal downward type is slightly advanced, and the arc downward type is the most advanced.

What cleaning measures are available for the rolling machine?
(1) Automatic center alignment.
Roll forming of the sheet metal is mainly completed by the rolling effect of the rolling machine. When the sheet is fed into the rolling machine, it must be ensured that the front edge of the sheet is parallel to the outer circumference of the roll, so that the rolled parts have high precision and high quality. The automatic center alignment process of the blade in the automatic feeding device is mainly completed by the servo motor driving the center alignment rod. Then the sliding device pushes the sheet to the feeding position of the rolling machine and waits for the sheet to be rolled.
Given the peculiarity of the plate shape, the vacuum suction receiving device is mainly used for plate transport. The plate rolling machine can roll plates of different sizes. Therefore, the position of the suction cups in the vacuum suction cup receiving device of the automatic feeding device must have a suitable adjustment function to be suitable for handling plates of different sizes.
(3) The speed and stability of the handling process.
In order to meet the working rhythm of the sheet metal bending machine and the safety of the handling process, the automatic feeding plate handling process should have better speed and stability to prevent overshooting and vibration during the handling process.
The automatic feeding device of the sheet bending machine is mainly composed of a sheet metal carriage, an actuator, a sheet metal transfer mechanism and an auxiliary mechanism. Sheet metal trolleys are used for storing sheet metal to be rolled. The main function of the actuator is to transport the sheet metal to be rolled up on the sheet metal trolley to the feeding platform. The transportation process of sheet metal is mainly applied to the Cartesian coordinate manipulator and vacuum suction cup receiving device. In industrial automation systems, it is often necessary to pick up and transport workpieces, and vacuum suction cups are widely used as vacuum manipulators.
1. Clean the components of the sheet metal rolling machine, especially the connection place;
2. When assembling the sheet metal rolling machine, the principle should be followed from the inside to the outside, first down and then up;
3. During assembly, the use of the same assembly tools or observe assembly work in the same orientation;
4. During the assembly process, the transmission should be carried out in strict accordance with the design drawings, and the dimensions and specifications should be strictly checked.
In actual operation, in order to ensure that the installation quality of pipeline construction equipment meets the construction requirements, targeted solutions must be taken according to the problem and its cause. The following will explain the installation of pipeline construction equipment before, during and after installation.
Here is the content list:
l Regarding the control of pipeline construction equipment before construction.
l Regarding the control of pipeline construction equipment during construction.
l Regarding the control of pipeline construction equipment after construction.
Regarding the control of pipeline construction equipment before construction.
Before construction, in order to ensure that the material of the pipeline construction equipment used meets the industrial requirements, strict inspections need to be repeated, including repeated verification and review of the construction drawings, and careful inspection of the pipeline processing drawings to ensure that the pipelines in the drawings The processing regulations and calculated data meet actual requirements.
In addition, it is necessary to check whether the pipeline construction equipment required for installation has a quality certificate and whether the specifications and models of the pipeline correspond to the certificate, and whether it meets the corresponding installation requirements of the pipeline construction equipment.
Before construction, check the pipeline construction equipment for damage and other quality defects that affect the construction. In order to get a more accurate understanding of the pipe material, professional quality inspection instruments can be used. For example, high-pressure pipelines can be detected by the monitoring method of magnetic flaw detection. Ensure that the material of pipeline construction equipment meets industrial production requirements.
In terms of capital investment in the installation of pipeline construction equipment, manpower, materials, and instruments and tools used are the main capital consumption objects. Manufacturers need to have a detailed grasp of the use of funds to reduce costs as much as possible without affecting the quality of the project. When selecting manpower, low-skilled workers should be employed for jobs with low technical requirements. When selecting materials, pipeline construction equipment is often selected for comparison. Before construction, it is also necessary to conduct professional skills training for construction personnel to enhance their work skills.
Regarding the control of pipeline construction equipment during construction.
During the installation process, when the pipe is cut according to the drawings, it is necessary to use the corresponding operating tools and methods to cut according to the construction requirements and the pipe material to avoid damage to the pipe. When connecting pipes, the main construction methods are hot bending and cold bending.
Hot bending is performed in the pipeline construction equipment installation process after heating treatment, specialized functional personnel make it deform according to the construction requirements; cold bending is carried out at room temperature, the pipeline construction equipment deforms according to the construction requirements. Since heating will cause mechanical deformation of the pipeline, cold bending processing methods are mostly used in the construction process. In hot bending, different heating fuels, heating pipeline construction equipment, and heating techniques must be used according to different pipeline materials and construction requirements, and the heating temperature must be strictly controlled.
The hot-bent pipes must be maintained after installation to ensure their quality and durability. When welding, due to the different materials of the pipeline and the different connection methods of the pipeline during the laying process, the welding tools and techniques selected will be different. The welding technology requires high requirements, and the construction personnel need to have good experience and technology to make the pipeline can be Therefore, experienced technicians should be selected for the welding process during the installation of pipeline construction equipment, and professional equipment should be used for testing after the welding is completed to see if seamless welding has been achieved to meet the engineering requirements.
Regarding the control of pipeline construction equipment after construction.
After the completion of the pipeline construction equipment, quality inspection and maintenance of the pipeline are required. When performing quality inspections, professional monitoring equipment is generally used, such as radiographic inspection, which can achieve non-destructive inspection. When the test is in progress, a unified test standard shall be adopted in compliance with the relevant technical standards, with special attention to whether the units used are unified.
After the pipeline construction equipment is installed, in order to better ensure the quality of the pipeline, it needs to be treated with anti-corrosion treatment. Generally, paint is applied to isolate the pipeline and the air in the water and oxygen from chemical reaction and rust. Extend the service life of the pipeline, and also improve the safety of operations for those who perform production operations.
Pipeline construction equipment is widely used in industrial production and has strict quality requirements. Due to the different pipeline construction equipment used in different industrial production environments, it is easy to have some problems during the installation process, which will affect the quality of the installation project. To ensure pipeline construction the installation quality of equipment meets the requirements of industrial production, and the installation process needs to be carried out in strict accordance with the construction requirements.
When using the tank welding machine, the operator puts the lamp tube into the fixture, presses the start button, the two pressing cylinders descend to position the workpiece in the ultrasonic mold cavity, and then the ultrasonic welding head acts to trigger the ultrasonic wave, and the welding head carries out the workpiece. After welding and welding, the cylinder drives the upper die to reset, the pressing cylinder rises, and the operator takes out the workpiece to complete one operation.
What are the characteristics of automatic vertical welder?
What is the working principle of tank welding machine?
What is the working effect of tank welding machine?
Automatic vertical welder is high-efficiency automatic welding equipment that uses current feedback closed-loop control of vehicle lift. The thickness of the welded joint can be up to 50mm at one time. Mainly used for thick plate welding in petroleum, chemical, blast furnace, shipbuilding and other industries. EGW vertical gas electric welding machine is a kind of high-efficiency automatic welding equipment improved according to the current feedback closed-loop control welding trolley. The main feature of automatic vertical welder is that the thickness is from 10mm to 50mm in one pass of forced water cooling. At the same time, the molten pool level is automatically controlled, and the wire extension length is automatically adjusted. Small size and light weight welding trolley, flexible and modular, easy to update and easy to use. Widely used in petroleum, chemical, blast furnace thick plate welding and shipbuilding industries.
In most cases, the EGW used in the tank welding machine uses carbon dioxide gas as a protective gas, but sometimes pure argon, argon carbon dioxide mixed gas, argon oxygen mixed gas, and argon helium mixed gas are used. Welding wire is often made of flux wire that creates slag and provides an aesthetically pleasing weld, but sometimes solid wire is used.
Tank welding machine surrounds the molten pool with the base metal end and copper lining or refractory lining material, and can perform vertical upward welding while preventing dripping of molten metal, so it can be welded in a single pass (single operation) Welding of thick plates. Its applications include welding of vertical butt joints such as ship side outer panels, bridge construction, storage tanks, pressure vessels, etc.
Tank welding machine is usually used for welding thicker materials such as low carbon steel and medium carbon steel, and can also be used for welding austenitic stainless steel and other metal alloys. The thickness of the plate is 12~80mm the most suitable. If it is larger than 80mm, it is difficult to obtain a sufficient and good protective effect, resulting in pores in the weld, uneven penetration and incomplete penetration. The length of the welded joint is generally unlimited. Single-layer welding is the most commonly used welding method, but multi-layer welding can also be used.
