Abstract

The invention relates to a silicon steel sheet punching process and device for simultaneously punching two holes, belonging to the technical field of transformers. The technical scheme is that the silicon steel sheet punching device comprises a punch press (1), a guide shaft (2), a guide sleeve (3), a slideway (4) and a double punch pin (5), wherein the guide shaft and the guide sleeve are arranged between a stroke slider at the upper side of the punch press and a bottom working table so as to improve the precision of the punch press; the slideway is machined on the guide sleeve, the double punch pin is arranged on the slideway and the distance of the double punch pin can be freely regulated in a certain spacing so as to satisfy the distance between the two holes on an iron yoke; and a lower punch die is arranged on the slideway of the bottom working table and is aligned with an upper punch pin in the debugging process so that the two holes can be simultaneously punched. The silicon steel sheet punching process and device which are provided by the invention have the positive effects that: the two holes can be simultaneously punched through the punch press; the punching on an iron yoke piece can be completed through one-time punching; and therefore, the efficiency is increased by more than one time and the punching quality is improved.

Description

The silicon steel sheet punching technology and the equipment in two holes of a kind of while punching press
Technical field
The present invention relates to the silicon steel sheet punching technology and the equipment in two holes of a kind of while punching press, belong to the transformer technology field.
Background technology
The dry-type distribution transformer main body is insulated by unshakable in one's determination and winding and device body and forms, in order to reduce noise, structurally to guarantee the clamping force of folder to iron core, at present, the general method that adopts is two center holes that symmetry is set on the iron yoke, fastening by screw rod makes folder produce good clamping force to the iron yoke, thereby reduces noise.But under the situation that does not have silicon steel sheet numerical control cut-to-length, by common punch press punching, can only once dash a hole, measure the spacing in two holes then, dash second hole again, process velocity is slow, and the spacing in two holes also is not easy to guarantee precision, thereby has directly influenced closed assembly speed unshakable in one's determination and end face flatness.
Summary of the invention
The silicon steel sheet punching technology and the equipment that the purpose of this invention is to provide two holes of a kind of while punching press, enough pass through punch press, dash two holes simultaneously, one-off hole-piercing just can be finished the punching to an iron yoke sheet, efficient is enhanced about more than once, punching quality also is improved, and solves the problems referred to above that background technology exists.
Technical scheme of the present invention is:
The silicon steel sheet punching technology in two holes of a kind of while punching press comprises following processing step: 1. guide shaft and guide pin bushing are installed, to improve the precision of punch press between the stroke slider of punch press upside and bottom workbench; 2. on guide pin bushing, process slideway, two drifts are installed on the slideway, and make two drift free adjustment distances in a determining deviation, satisfy the distance between two holes on the iron yoke; 3. will descend punch die to be installed on the slideway of bottom workbench, and in debug process, make it to align, can dash two holes simultaneously with upper punch.
The silicon steel sheet punching apparatus in two holes of a kind of while punching press comprises punch press, guide shaft, guide pin bushing, slideway, two drift, and guide shaft and guide pin bushing are installed between the stroke slider of punch press upside and bottom workbench, to improve the precision of punch press; On guide pin bushing, process slideway, two drifts are installed on the slideway, and can make two drift free adjustment distances in a determining deviation, satisfy the distance between two holes on the iron yoke; Following punch die is installed on the slideway of bottom workbench, and makes it to align with upper punch in debug process, can dash two holes simultaneously.
Good effect of the present invention is: can pass through punch press, dash two holes simultaneously, one-off hole-piercing just can be finished the punching to an iron yoke sheet, and efficient is enhanced about more than once, and punching quality also is improved.
