Problems solved by technology

[0002] In production practice, it is often necessary to process various holes such as round holes, square holes, and strip holes that are symmetrical to the plane passing the central axis on the steel pipe. If the press is used to process twice, the efficiency is low and the processed holes The symmetry accuracy is poor, so it is necessary to have an ideal processing technology for processing a pair of symmetrical holes on the press at the same time.

Embodiment Construction

[0019] The method for processing symmetrical holes in thin-walled steel pipes is to use the die to process the symmetrical holes on the thin-walled steel pipe on a press, and the die is mainly composed of the die handle (1), the upper template (2), The side plate (3), the base (4), the die (5), the punch mechanism (6), the round washer (7), the round nut (8) and the Spring I (9) constitutes, and described punch mechanism (6) mainly is by described screw I (10), described moving base (11), described cylindrical pin (12), described guide post (13) and all Said punch (14) constitutes. The mold handle (1) is connected with the upper template (2) by four screws. The upper template (2) has the slope I (15). The moving seat (11) has the slope II (16) and the groove I (17). The die (5) has the die groove (18) and the plane I (19), and the die groove (18) is equipped with an elastic body matched with the die groove (18). The base (4) has the guide rail groove (20), the groove II (2...

Abstract

The invention relates to the technology of press machine machining, in particular to a method for machining a pair of holes which are symmetrical relative to a plane which passing a central axis on a thin-wall steel pipe through a stamping die. The stamping die mainly comprises a die shank, an upper die plate, a lateral plate, a base, a cavity die, a core die mechanism, a round washer, a round nut and a spring I; the core die mechanism is mainly formed by a screw I, a mobile seat, a cylinder pin, a guide pillar and a core die. The stamping die is reasonable in structure and convenient to install and adjust. The hole punching operation is convenient, the machining efficiency is high, and the hole punching symmetry accuracy is good.

Description

technical field [0001] The invention relates to a press processing technology, in particular to a processing method for processing a pair of symmetrical holes relative to a plane passing through a central axis on a press by using a die to process a thin-walled steel pipe. Background technique [0002] In production practice, it is often necessary to process various holes such as round holes, square holes, and strip holes that are symmetrical to the plane passing the central axis on the steel pipe. If the press is used to process twice, the efficiency is low and the processed holes The symmetry accuracy of the hole is poor, so it is very necessary to have an ideal processing technology for processing a pair of symmetrical holes on the press at the same time. Contents of the invention [0003] In order to solve this problem, the present invention provides a method for processing symmetrical holes in thin-walled steel pipes, which adopts die processing on a press, which can c...
