Description

Technical Field

[0001] The utility model relates to the technical field of trimming devices, in particular to a trimming device for sheet metal stamping cabinets. Background Art

[0002] With the continuous development of industrial technology, sheet metal parts have been widely used in many fields due to their relatively thin thickness and excellent processing performance. Among them, sheet metal stamping cabinets are metal structural parts made by combining sheet metal processing technology and stamping technology. During the processing of sheet metal stamping cabinets, processes such as cutting and stamping are usually required. However, the edges after cutting and stamping often have problems such as burrs and unevenness. Therefore, the trimming process has become an indispensable part of sheet metal part processing;

[0003] After retrieval, a Chinese patent with the publication number CN214054693U discloses a trimming device for sheet metal part processing, including a holding plate. A pair of first modules are fixedly connected to the surface of the holding plate. A first moving block is arranged on the surface of the first module. A second module is fixedly connected to the surface of a pair of the first moving blocks. A second moving block is arranged on the surface of the second module. An adjusting box is fixedly connected to the surface of the second moving block. A first support rod is arranged inside the adjusting box through a bearing. A first fixing plate is fixedly connected to the top of the first support rod. A threaded hole is formed on the surface of the first fixing plate. A threaded rod is arranged inside the threaded hole. An extrusion plate is arranged at the bottom of the threaded rod through a bearing. A limiting block is fixedly connected to the side wall of the extrusion plate. An installation frame is fixedly connected to the surface of the holding plate and on one side of the first module through a first electric push rod;

[0004] In the above technology, although the height of the first grinding wheel and the second grinding wheel is adjusted by controlling the telescopic design of the first electric push rod and the second electric push rod, so as to trim workpieces with different thicknesses, the above trimming device can only drive the first grinding wheel and the second grinding wheel to move up and down. Such a design makes the traveling routes of the first grinding wheel and the second grinding wheel relatively single, and it is impossible to flexibly adjust the path according to the specific shape of the sheet metal part and the trimming requirements. This results in that during the trimming process, manual assistance or multiple adjustments of the position of the sheet metal part are often required, reducing the work efficiency;

[0005] Therefore, the utility model provides a trimming device for sheet metal stamping cabinets. Summary of the Utility Model

[0041] In this embodiment, the cylinder 29 is used to drive the clamping plate 30 to move, so that the two clamping plates 30 clamp the cabinet, enabling the cabinet to remain stable during the edge trimming process.

[0042] Working principle: First, place the cabinet to be trimmed on the base 1. At this time, turn on the first adjustment motor 7 to adjust the angle between the first electric telescopic rod 6 and the second electric telescopic rod 8 through the first adjustment motor 7. Then, turn on the second adjustment motor 10 to adjust the angle between the grinding head 11 and the second electric telescopic rod 8 through the second adjustment motor 10.
