Why does the rolling machine need to be sealed?

The reliability and service life of the seals in the hydraulic system of sheet metal bending machine are important indicators to measure the quality of the hydraulic system.

In addition to gap seals, seals are used to keep the gap between two adjacent coupling surfaces below the minimum gap through which the liquid to be sealed can pass. The seals in the hydraulic system of sheet metal bending machine are usually contact seals. There are two types of self-sealing compression seals and self-sealing self-clamping seals, also known as lip seals. However, the factors influencing the performance of different seals in the hydraulic system of the sheet metal rolling machine are different, just as with the three-roller roller. In fact, the seal of the hood is still influenced by temperature, pressure and the existing medium.

What is forbidden to workers when operating a rolling machine?

During the measurement of the roundness of dimensions, the operator of the rolling machine is forbidden to stand on the rolled cylinder, and it is forbidden to stand on the workpiece to be machined. For some difficult-to-process workpieces, such as thicker or larger diameters, high hardness or strength of raw materials, etc., this should be done by a small number of operations simultaneously to achieve the desired effect. For some workpieces with smaller diameters, they should be rolled in the middle of the rollers for operation.

What is a hydraulic rolling machine?

The main features of hydraulic plate rolling machine: the upper roller of the machine can be lifted vertically, and the hydraulic transmission of vertical lifting is achieved by the action of the hydraulic oil in the hydraulic cylinder on the piston rod; The torque is provided, and there are tensioners under the lower roller that can be adjusted. The upper roller has the shape of a drum, which improves the straightness of the product and is suitable for tanks with various cross-sectional shapes with ultra-long specifications.

Hydraulic rolling machines can roll metal plates into circles, arcs and conical workpieces within a certain range. The two lower rollers of this model are active rollers and the upper rollers driven rollers. It is widely used in shipbuilding, boiler, aerospace, hydropower, chemical, metal structure and mechanical engineering industries.

The hydraulic rolling machine is suitable for bending metal plates. It can roll circular, arc and conical workpieces within a certain range and has the function of pre-bending the end of the plate. The two lower roles of this model are active roles. Horizontal movement, the upper roller is a driven roller and can move up and down. There are mechanical and hydraulic movements. The driveshafts are connected by cardan couplings.

How to use a tank welding machine?

 

Introduction to the advantages and disadvantages of tank welding machine.

The advantages of tank welding machine after welding are widely used in various fields, especially for parts that require high strength. It can instantly connect the same metal material (also can connect dissimilar metals, but the welding method is different) permanently. After heat treatment, the weld seam has the same strength as the base material and is well sealed, which solves the problems of sealing and strength for the manufacture of storage gas and liquid containers.

 

However, when the tank welding machine is in use, a certain magnetic field will be generated around the welding machine. When the arc burns, radiation will be generated to the surroundings. The arc light contains infrared rays, ultraviolet rays and other light species, as well as metal vapor and smoke and other harmful substances. Adequate protective measures must be done at the time.

 

Welding is not suitable for high-carbon steel welding. Due to the process of crystallization, segregation and oxidation of weld metal, the welding performance of high-carbon steel is poor, and it is easy to crack after welding, resulting in hot and cold cracks. Low carbon steel has good welding performance, but the process must be handled properly. Derusting and cleaning are more cumbersome. Sometimes the weld will have defects such as slag inclusion, cracks, pores and undercuts, but proper operation will reduce the occurrence of defects.

 

Matters needing attention when cleaning tank welding machine.

When cleaning the tank welding machine, it is necessary to grind the inner and outer burrs of the tube end to make the tube end flush without burrs, and wipe it clean with alcohol. Manual tungsten argon arc welding is used for positioning, and the location of the positioning solder joints should not be too high, the current should not be too large, and the penetration is not allowed, the number of solder joints should not be less than 2, and the solder joint diameter should not be greater than 6mm.

 

If the position of the tank welding machine is not used properly, the position of the welding point will deviate from the neutral line of the welding butt surface. Due to the regular shape of the girth welding seam, the position welding point that deviates from the welding seam cannot be covered by the normal welding seam, resulting in The positioning welding spot is on the edge and outside of the welding seam, which makes the welding seam surface poorly formed.

 

How to use a tank welding machine?

l Check the connection

After completing the wiring of the tank welding machine, you must check each installed connector to confirm that it is well connected before starting to operate the equipment. Its contents include:

1. The line connection is correct and reasonable, and the grounding must meet the specified requirements

2. The magnetic work piece gripper shall not have attached metal particles and splashes on its contact surface;

3. The coiled welding cable should be unrolled before use to avoid overheating and insulation damage;

4. When it is necessary to alternately use different lengths of cables, insulating joints should be provided to ensure that useless lengths can be disconnected when not needed.

l leakage

There must not be any leakage of cooling water, shielding gas or engine oil that affects the safety of welders.

l Work suspension

When the welding work is suspended (for example, during breaks), the output terminal of the equipment or tank welding machine must be turned off or the power supply must be cut off.

l Mobile welding machine

When you need to move the tank welding machine, you must first cut off the power supply at its input end.

l Equipment not used

The metal electrode and carbon electrode must be removed from the welding tongs when not in use to eliminate the risk of electric shock to personnel or conductive objects. The welding tongs must be placed out of contact with persons, electrical conductors, flammable objects or compressed air bottles when not in use. The welding torch of the semi-automatic welding machine must be properly placed when not in use to avoid accidental activation of the gun body switch.

l maintain

All arc welding equipment must be maintained at any time and kept in a safe worki.

Tank top and upper (the first layer) wall plates are lifted first and then install and weld wall plates of tank body. Self locking hydraulic jack and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters hydraulic jack, upper clamp fastens and lifts lifting rod and expansion ring and mobilize tank (including tank top) to ascend upward. When oil returns to jack, upper clamp returns with piston and lower clamp automatically fastens lifting rod without gliding. The simple chunk type hydraulic jack repeats the movement and make lifting rod ascend with tank to designated height (spare height for next layer of plate). After butt weld of next layer of wall plates, open upper and lower loosening device and loosen upper and lower clamp to make lifting rod and expansion ring descend to lower expanded and welded rib plate of the next layer of wall plates and then lift. Repeat the process and ascend welded tan till the last layer of wall plates are installed and welded. The installation of the whole storage tank is completed.
