Equipment and method for welding and deburring of round-link chain

Abstract

The invention discloses equipment and a method for welding and deburring of a round-link chain. The equipment comprises a clamp, a deburring knife mechanism, a rotating arm, a rotating mechanism and a rack. The rotating arm is arranged on the rotating mechanism, the rack is arranged at one side of the rotating mechanism, and the clamp comprises a fixed clamp and a movable clamp which are respectively arranged at the two sides of the rack 5. And the clamp is used for clamping the to-be-deburred round-link chain. A deburring knife mechanism is arranged on the upper side of the rotating arm and used for deburring of the clamped round-link chain in the rotating process. By means of 180-degree rotation, 360-degree rotation around the welding chain arm is formed, a welding area with the consistent smooth area boundary line is formed, deburring is thorough, and no dead space is left.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a device and method for welding and deburring circular link chains. Background technique [0002] The circular link chain is a kind of coal mine scraper machine equipment, which is the transportation component, and together with the scraper, it forms the transportation device. The transportation volume is also increasing, and the specifications of the round link chain are also increasing accordingly. [0003] The round link chain is a round ring made of round bars, and a long chain connected by the word "ten". There are two methods of welding and hot weaving and cold welding, both of which use flash butt welding to form a circular weld after welding. As far as the process requirements are concerned, it is necessary to de-puncture the circular weld to form a smooth circular weld. The welding equipment that adopts the hot-weaving and cold-welding process...

AI Technical Summary

Problems solved by technology

[0004] The existing vertical stab removal process is to fix the workpiece on the equipment fixture, and the tool moves vertically up and down to achieve the purpose of stab removal. However, since the circular link chain is fixed on the equipment as a whole, a compact ring (vertical ring) is connected to the lower part. , the inner width of the single ring is limited, and the operating space of the equipment is small, so the shape of the cutter body is small, which affects the rigidity of the cutter, and has the following disadvantages:

[0005] 1. The vertical de-stabbing process is prone to incomplete de-punching at the interface, forming high edges, poor ring shape, and the chain is likely to cause wear and tear on the joint during use;

[0006] 2. Both the tool and the workpiece are positioned on the equipment, but because there is a certain gap at the interface between the inner knife and the outer knife, the gap cannot achieve the stab removal effect. Sometimes the positioning is not good and the base material may be damaged, resulting in workpiece defects and severe tool damage. wear and tear

[0007] 3. The area formed at the welding place is different. Since the up and down strokes of the tool are controlled by the equipment (generally the same stroke), the shape and size of the ring-shaped area formed after deburring cannot meet the standard requirements.

[0008] 4. The knife is prone to serious damage due to the different cutting depth

[0009] 5. The tool body is large, difficult to repair, and the cost is high
