Description

Technical Field

[0001] The utility model relates to the technical field of metal product processing, in particular to a hemming machine for metal products that prevents skew. Background Technique

[0002] A hemming machine is a simple bending machine, which can be either manual or motorized. The simplest method is to firmly fix a steel plate on the machine tool workbench with a model having a bending radius, and the protruding part of the material is placed on another workbench that can rotate along the center of the bending radius. When the movable workbench rises, it bends the stainless steel into the required angle. Obviously, when bending, the stainless steel slides on the workbench. Therefore, to prevent scratching the stainless steel, the surface of the workbench must be smooth. In the actual processing process, the surface of the stainless steel is usually protected with a plastic film;

[0003] In the prior art, a hemming machine completes the hemming process of a metal sheet through a hemming tool. However, the existing hemming machine does not have a multi-directional limiting setting, which easily causes the metal sheet to tilt during processing, affecting the overall effect after processing of the metal sheet. Moreover, the hemming machine does not have an automatic mechanical control setting, and manual operation is required for feeding and conveying, which increases the input cost of manual labor. And there are certain safety hazards when manually feeding, thus reducing the safety of operating the hemming machine and improvement is needed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hemming machine for metal products that prevents skew, so as to solve the problems that the metal products are prone to tilt when the existing hemming machine for metal products performs hemming, and manual feeding is required during the conveying of metal products, the process is cumbersome, and the safety is poor as mentioned in the above background technique.

[0005] To achieve the above object, the present utility model provides the following technical solution: A hemming machine for anti-warping metal products, including a base, a guide groove is provided at the top of the base, and guide columns are installed on both sides inside the guide groove. A baffle is installed at the top of the base. A hemming mechanism is provided at the top of the base, and a fixed shaft is installed inside the hemming mechanism. A first hemming cylinder is sleeved outside the fixed shaft. A baffle is installed on one side of the top of the base away from the hemming mechanism. A rotating shaft is connected inside the hemming mechanism, and a second hemming cylinder is installed between the rotating shafts. Support plates are installed on both sides of the top of the base, and gears are installed inside the support plates through connecting shafts.

Lower clamping seats are installed on both sides of the top of the placement seat, and an upper clamping seat is movably installed on the top of the lower clamping seat. A fastening bolt is connected between the upper clamping seat and the lower clamping seat. Adjusting lead screws are installed on the top of the upper clamping seats. The adjusting lead screws extend into the inside of the upper clamping seats and are installed with fixing plates. A moving motor is installed on one side outside the support plate, and one end of the moving motor penetrates through the support plate and is connected with the connecting shaft between the support plates. Limiting grooves are provided on one side of the support plates, and limiting plates are installed inside the limiting grooves.

[0006] When using a hemming machine for anti-warping metal products with this technical solution, it can improve the accuracy of hemming metal products during use, limit and fix the metal products during hemming, prevent the metal products from skewing during transportation, and avoid the possible hemming deviation and unsafe operation in manual transportation.
