An improved workpiece bending device

Abstract

The invention discloses an improved workpiece bending device which comprises an operation part and a base part arranged at the lower end of the operation part. The operation part internally comprises a pressure applying arm rod, an upper mold plate and a driving arm rod, the two ends of the pressure applying arm rod are each fixedly provided with an insertion shaft extending downwards, a lower mold plate corresponding to the upper mold plate is arranged at the upper portion of the base part, a slot is formed in the position, corresponding to the lower end of each insertion shaft, in the base part, sliding grooves arranged in a left-and-right corresponding manner are formed in the position, between the slots, of the base part, and a separating block fixedly connected with the base part is arranged between the sliding grooves; the upper portion of each sliding groove is provided with a through groove penetrating a body of the base body and communicated with the inner bottom face of the lower mold plate, and an ejection block is arranged in each through groove; and a sliding cavity is formed in the bottom face of each sliding groove, a sliding rail is arranged on the inner bottom face of each sliding cavity, a sliding rod is arranged in each sliding groove in a sliding manner, a tension spring is arranged between each sliding rod and the separating block, and a sliding hole is formed in the upper portion of each sliding rod. The improved workpiece bending device is simple in structure, automatic ejection can be achieved after punching is completed, the manufacturing cost is low, and maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of workpiece bending, in particular to an improved workpiece bending device. Background technique [0002] At present, bending devices are often used in the bending process of workpieces. Some traditional bending devices require manpower to apply force by themselves. The operation process is not only time-consuming and labor-intensive, but also inefficient. However, due to the material of the workpiece itself or the excessive stamping force, the stamped and bent workpiece is bonded to the mold, and it is not easy to fall off and needs to be separated manually. The operation is extremely dangerous and the processing efficiency is low, and there is a large safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved workpiece bending device, which can solve the above-mentioned problems in the prior art. [0004] The present invention...

[0002] At present, bending devices are often used in the bending process of workpieces. Some traditional bending devices require manpower to apply force by themselves. The operation process is not only time-consuming and labor-intensive, but also inefficient. , but due to the material of the workpiece itself or the stamping force is too large, the stamped and bent workpiece is bonded to the mold, and it is not easy to fall off and needs to be separated manually. The operation is extremely dangerous and the processing efficiency is low, and there is a big safety hazard
