Die for bending machine and capable of changing any bending angle

Abstract

The invention discloses a die for a bending machine capable of changing any bending angle, and relates to the technical field of bending machines. The die comprises an upper die and a lower die, wherein the middle parts of the upper die and the lower die are respectively provided with uniformly-distributed telescopic grooves, and the bottom of each telescopic groove is fixedly connected with a first spring. According to the die for the bending machine and capable of changing any bending angle, toothed bars are matched with pressing plates for use, when the die is used, a sample is taken and placed between the upper die and the lower die, the angular tip of a plate faces downwards and is located in the middle of the pressing plates of the lower die, and then the upper die and the lower diemove towards each other, as the toothed bars are elastically connected with the first springs, the toothed bars can be adjusted up and down, meanwhile, as the pressing plates can rotate, the pressingplates can gradually rotate along with second springs of the upper die and the lower die, and finally the pressing plates rotate to the same angle as the sample, so that the effect of changing the bending angle is achieved, the operation is simple, the upper die and the lower die do not need to be disassembled, the disassembly time is saved, the production efficiency is improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of bending machines, in particular to a mold for bending machines capable of changing any bending angle. Background technique [0002] The bending machine is often used in sheet metal processing. The cut sheet needs to be folded into a certain angle before it can be put into use. At this time, it is necessary to use the bending machine to bend the sheet into a specific angle for later use. [0003] Most of the upper mold and lower mold on the bending machine are fixed in shape, which leads to the fixed bending angle of the upper mold and the lower mold, and the bending angle cannot be changed. When the bending angle needs to be changed, only the upper mold and the lower mold can be loaded and unloaded. , the process is cumbersome, and the loading and unloading process is time-consuming. The loading and unloading process requires manual operation, and the labor load is large, which increases the labor intensi...

[0003] Most of the upper mold and lower mold on the bending machine are fixed in shape, which leads to the fixed bending angle of the upper mold and the lower mold, and the bending angle cannot be changed. When the bending angle needs to be changed, only the upper mold and the lower mold can be loaded and unloaded. , the process is cumbersome, and the loading and unloading process is time-consuming. The loading and unloading process requires manual operation, and the labor load is large, which increases the labor intensity of the workers and reduces the work efficiency of the bending machine. Prepare multiple sets of upper and lower molds, which increases production costs
