technical field

The invention relates to the technical field of processing and bending, in particular to a processing method of a bending device for production and processing of hardware accessories.

Background technique

Hardware accessories refer to machine parts or components made of hardware, as well as some small hardware products. General hardware accessories include pulleys, casters, joints, etc. Hardware accessories can be used alone or as auxiliary tools. Most of the hardware products are not final consumer goods, but As ancillary products, semi-finished products and tools used in the production process of industrial manufacturing, bending is a very common and important step in the processing of accessories, and bending equipment is a very important and common equipment. In the application number The Chinese patent 202222112985.X discloses "a bending device for the production and processing of hardware accessories, including a processing platform, a support frame is fixed on the upper end of the processing platform, and two symmetrically arranged supports are fixed on the upper end of the processing platform. block, the inner top of the support frame is fixed with a hydraulic cylinder, the rod head of the hydraulic cylinder is fixed with a horizontal moving plate, the upper end of the horizontal moving plate is fixed with a plurality of vertical limit rods, and the horizontal moving The bottom of the plate is fixed with a stamping block. In this device, by setting the vertical limit plate with adjustable position at the end of the support block, in combination with the scale line above the guide rod, it is possible to realize the alignment between the vertical limit plate and the stamping block. The control of the distance between them can realize the precise bending of the same type of hardware accessories, without the need for measuring and marking before bending, which can effectively increase its work efficiency, and it is convenient to use for bending processing of different types of hardware accessories, which can be effectively Increase the applicability of the bending device."

This comparison document only solves the need to manually place the parts on the bending device. Manual placement will easily lead to inaccurate bending positions of the hardware parts, which will affect the processing accuracy of the hardware parts. The general processing method is before the processing of the hardware parts. Measuring and scribing will cause a large amount of labor, which is not convenient for the bending of large quantities of hardware accessories. However, in the process of bending, after the bending of the processed parts is completed, the finished processed parts cannot be unloaded. , It also needs to be unloaded by the staff's own operation. If the processing time is long, the labor intensity of the staff will still be increased, and when the staff's hand is stretched under the bending end, if a false trigger occurs, it will The situation that the staff is injured occurs, it is not safe and reliable enough, and when automatic blanking is performed, there will also be a problem that the processed parts that are blanked cannot be received and collected.
