Problems solved by technology

[0002] At present, when punching holes on ordinary punching machines, only holes with regular diameters can be punched. When processing parts, it is required to punch irregular holes along the edges, and it is necessary to convert two or more sets of molds to process the shape. This processing method Low production efficiency and long cycle time are not suitable for mass production

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings: the mold for punching irregular turning holes in batches on the steel plate includes a bottom plate (1), an upper plate (4), a lower fixing plate (2), a lower supporting plate (3), an upper fixing plate Plate (5), upper support plate (6), irregular turning punch (7), guide post (8), positioning clamp (9) and positioning pin (10).

[0015] Install the lower supporting plate (3) on the lower fixing plate (2), then install it on the bottom plate (1), and install the punch (7) along the irregular hole on the upper supporting plate (6), and then connect it with the upper The fixed plates (5) are installed together, and then they are installed together on the upper plate (4), and the lower die is matched with the cutting edge of the upper die by debugging. The guide post (8) connects the bottom plate (1) and the upper plate (4), so that the upper plate (4) can move linearly in...

Abstract

The invention discloses a die for punching irregular edge-turned holes in batch on a steel plate. The die comprises a bottom plate, an upper plate, a lower fixing plate, a lower supporting plate, an upper fixing plate, an upper supporting plate, irregular edge-turned hole punches, guide columns, positioning weights and positioning pins. The lower supporting plate is mounted on the lower fixing plate and then fixed to the bottom plate; the upper supporting plate is mounted on the upper fixing plate, the punches are embedded into corresponding positions of the upper supporting plate, then the upper supporting plate is fixed to the upper plate, and the bottom plate and the upper plate are connected through the guide columns so that the upper plate can linearly move in the axial direction of the guide columns. Cutting edges of an upper machining part and a lower machining part for the irregular edge-turned holes are matched, and the two guide columns are distributed on the two sides of the rear portion of the die. The punches can be freely replaced according to machining shapes, and meanwhile, the die can position parts according to the shapes and the machining sizes of the machined parts. The irregular edge-turned holes can be machined without replacing the die, work procedures are reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to a mechanical processing device, in particular to a mold for batch punching irregular edge holes on steel plates. Background technique [0002] At present, when punching holes on ordinary punching machines, only holes with regular diameters can be punched. When processing parts, it is required to punch irregular holes along the edges, and it is necessary to convert two or more sets of molds to process the shape. This processing method The production efficiency is low, and the cycle is long, which is not suitable for mass production. Contents of the invention [0003] The technical problem to be solved by the present invention is that batches of irregular turning holes can be processed without changing moulds, thereby improving production efficiency and reducing labor. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: one set of molds for punching irr...
