Problems solved by technology

[0002] The turret punch press uses the stamping die to perform punching processing and shallow drawing on the plate. The upper die is installed in the installation hole of the upper turret, and the lower die is installed in the corresponding installation hole of the lower turret mold holder. To prevent the lower die from jumping out of the die holder during the stamping process, it is necessary to use the cover plate to hold down the lower die, and the cover board needs to be positioned by at least two positioning pins when it is installed on the die holder. At the same time, it is necessary to ensure the parallelism between the pin holes of the cover plate and the parallelism between the positioning pins. Multiple precision is more difficult to process.

Embodiment Construction

[0013] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0014] ginseng figure 1 As shown, the positioning pin of the cover plate in the present invention includes a positioning pin 01 and a top wire 02. The positioning pin 01 is vertically fixed on the mold holder, the top wire 02 is movable on the mold holder, and the top wire 02 is perpendicular to the positioning pin 01. The positioning pin of the cover plate of the present invention has simple structure, simple material acquisition and easy processing.

Abstract

The invention discloses a cover plate positioning pin. The cover plate positioning pin comprises a positioning pin body and a top wire, the positioning pin body is perpendicularly fixed to a die supporting seat, and the top wire is movably arranged on the die supporting seat and is perpendicular to the positioning pin body. According to the novel cover plate positioning pin, the structure is simple, material obtaining is easy, machining is easy, meanwhile, the machining precision of a cover plate pin hole is reduced, and quick positioning of a cover plate is achieved.

Description

technical field [0001] The present application relates to the field of turret punch presses, in particular to a cover positioning pin. Background technique [0002] The turret punch press uses the stamping die to perform punching processing and shallow drawing on the plate. The upper die is installed in the installation hole of the upper turret, and the lower die is installed in the corresponding installation hole of the lower turret mold holder. To prevent the lower die from jumping out of the die holder during the stamping process, it is necessary to use the cover plate to hold down the lower die, and the cover board needs to be positioned by at least two positioning pins when it is installed on the die holder. At the same time, it is necessary to ensure the parallelism between the cover pin holes and the parallelism between the positioning pins, and the multiple precision is more difficult to process. Therefore need to propose improvement. Contents of the invention ...
