Problems solved by technology

The processing technology and processing equipment of this kind of non-ferrous metal pipes have the following deficiencies: one is that the process is incoherent and it is difficult to realize automatic production; The way of manual feeding, therefore, the labor intensity of the operators is relatively large; the third is to adopt two tube drawing processes of rough drawing and fine drawing, which have low production efficiency, high production cost, high energy consumption, and occupy more It is necessary to increase the investment in equipment, and at the same time, it is difficult to guarantee the straightness quality of the finished pipe; the fourth is that only one material pipe can be pulled in each production, so the production efficiency is low

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. The following description is by way of example, but the protection scope of the present invention should not be limited thereto.

[0035] The automatic pipe drawing machine of the present embodiment is composed of a feeding device 1, a pinch conveying device 7, a first-level auxiliary feeding device 10, a locking device 13, a second-level auxiliary feeding device 18, a die-drawing device 19, Tube pulling device 22 and power unit 33 constitute. The automatic tube drawing machine of the present embodiment is a four-out tube drawing machine, that is, four material tubes are drawn each time (it can also be two or six or eight or more).

[0036] The feeding device 1 is composed of a frame 2 and several support rollers 3 installed on the frame 2 (the number of support rollers 3 depends on the length of the processed pipe, and the general interval is 500-1000mm...

Abstract

The invention discloses a automatic cold drawing process for a colored metal tube, and relates to the technical field of colored metal tube processing. The process comprises the following steps of: feeding material tube, conveying the material tube at the first time, locking the opening of the material tube, conveying the material tube at the second time, clamping the material tube, drawing the material tube and resetting the material tube. The automatic cold drawing machine has the characteristics of reducing the labor intensity, improving the production efficiency, reducing the energy consumption, improving the product quality, realizing automatic and continuous production and the like, and is suitable for all types of colored metal tubes, such as a cold drawing aluminum tube, a cold drawing copper tube and the like.

Description

technical field [0001] The invention relates to the technical field of nonferrous metal pipe processing, in particular to a new automatic cold drawing process for nonferrous metal pipes and an automatic cold drawing machine thereof. Background technique [0002] In the prior art, the processing of non-ferrous metal pipes is to extrude the material pipe (i.e. the blank pipe) by the extruder, then manually lock the end of the material pipe (i.e. reduce its caliber), and then lock the end of the material pipe. The material tube at the mouth is installed in the tube-drawing mold, and the material tube is drawn by the tube-drawing car for the first time to become a semi-finished product; then, the above process is repeated again, and the second tube is drawn to become a finished product. The processing technology and processing equipment of this kind of non-ferrous metal pipes have the following deficiencies: one is that the process is incoherent and it is difficult to realize au...
