Machining process for metal pipes with punched holes

Abstract

The invention discloses a machining process for metal pipes with punched holes. A supporting plate is arranged on a hole punching tool operation platform, a horizontal pipe sleeve core column is arranged on the supporting plate, a transverse connecting plate is arranged at the upper end of the supporting plate, a cam is arranged on the transverse connecting plate through two vertical upward cam connecting blocks, and a handle is arranged on the cam. A punch mounting mechanism consisting of a stress plate and a punch fixing seat is arranged under the cam, a punch is arranged on the punch fixing seat, and a positioning mechanism is arranged on the pipe sleeve core column. During machining, a metal pipe is clamped on a feeding tool at first, one end of the metal pipe sleeves the pipe sleeve core column and is propped against the positioning mechanism, and then a knife on the feeding tool is started to cut the metal pipe; and while cutting, an operator pulls the handle of a hole punching tool with hands, so that the punch is pushed to finish hole punching of the metal pipe. By the machining process for the metal pipes with the punched holes, feeding and hole punching of the metal pipes can be finished on one working procedure, and only one operator is required.

Description

Technical field [0001] The invention relates to a metal pipe processing technology, in particular to a metal pipe processing technology with a punching hole. The technology can complete the blanking and punching of the metal pipe in one working procedure, and belongs to the technical field of metal pipe processing. Background technique [0002] In the processing of products in the workshop, it often involves the cutting of raw materials and then subsequent processing. For example, for steel pipes, after cutting the raw steel pipes into pipe sections of required length, a small hole needs to be punched at one end of the steel pipe according to the product structure requirements. Currently, blanking and punching are processed by different workers in different processes. It has the following shortcomings: 1. The blank after blanking needs to be transported to the punching process, which not only increases the transportation volume, but also affects the production efficiency. The t...

AI Technical Summary

Problems solved by technology

It has the following disadvantages. First, it is necessary to transport the blank after cutting to the punching process, which not only increases the transportation volume, but also affects the production efficiency. The transportation process also involves the planning of the transportation route; set of molds, so the requirements for the site occupation of molds are increased; 3. There are many personnel requirements, one worker for each process, plus transfer personnel, at least three workers are needed to complete blanking and punching, and labor costs increase
