Abstract

The invention discloses an automatic copper pipe drawing device. The automatic copper pipe drawing device comprises a machine body, a hydraulic system, an automatic clamping clamp and a drawing device body. The hydraulic system is arranged in the machine body. The automatic clamping clamp and the drawing device body are arranged on the upper surface of the machine body. The drawing device body further comprises a drawing hydraulic cylinder and a drawing length detecting travel switch. The problem of copper pipe drawing is solved, and the design mechanism is reasonable. The hydraulic cylinder is driven by the hydraulic system to draw a copper pipe clamped through the automatic clamping clamp, drawing is stopped when the drawing length detecting travel switch transmits signals, the automatic copper pipe drawing is achieved, and operation is fast and convenient.

Description

technical field [0001] The invention relates to the technical field of copper tube processing equipment, in particular to automatic copper tube drawing equipment. Background technique [0002] In the refrigeration industry, most of the throttling devices use capillary tubes. The inner diameter of capillary tubes is basically below 3mm. The inner diameters of ordinary refrigeration piping parts are larger than the outer diameters of capillary tubes. During the assembly and welding process, it is necessary to use a section of transition tube to connect the capillary tubes and refrigeration. There are several problems in the use of pipeline fittings and transition pipes as follows: 1. The addition of two welding spots increases the welding cost. 2. Increased quality risks such as welding blockage, welding tumor and noise. If a kind of copper tube drawing equipment can be designed to draw a large-diameter copper tube to form a copper tube with a small-diameter transition zone, ...
