Device and method for precise pressure point of thin-walled tube

Abstract

The invention discloses an accurate point pressing device for a thin-walled tube. The accurate point pressing device for the thin-walled tube comprises a clamp main body (1), point pressing strips (2) and a hydraulic cylinder (3), wherein a plurality of skewed slots (4) which communicate with one another are uniformly distributed in the top of the clamp main body (1); the dip angle of an inclined surface of each skewed slot (4) is 10-16 degrees; positioning mechanisms are further arranged on each vertical surface and positioned at the upper end and the lower end of the vertical surface; each positioning mechanism consists of a positioning block (11), an extension spring (12) and a guide hole (13) which is formed in the corresponding vertical surface; each positioning block (11) is arranged in the corresponding guide hole (13); the inside of each threaded hole is connected with an adjusting screw (7); the lower end of each adjusting screw (7) penetrates through a point pressing main body (6) and is connected with a raising plate (8); and each point pressing strip (2) is arranged in the corresponding skewed slot (4). The invention further discloses a point pressing method. The accurate point pressing device for the thin-walled tube has the beneficial effects that point pressing precision is high, point pressing distances can be changed optionally, the device is simple to operate, and point pressing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of dotting on thin-walled copper pipes, in particular to a device and method for precise pressing of thin-walled copper pipes. Background technique [0002] In the electronic production industry, thin-walled copper tubes are usually used to install precision parts. The precision parts are evenly distributed in the inner cavity of the thin-walled copper tube, and a groove is opened on the outer wall of the thin-walled copper tube. The outer wall of the thin-walled copper tube is extruded in the radial direction through the pressure point, so that the copper material is in contact with the precision parts, and the finished product is processed. The finished product is as follows: figure 1 with figure 2 As shown, the circular circle in the figure is the pressed point. The existing pressure point device cannot ensure that the copper material can contact the preset precision parts in the thin-walled copper tub...

AI Technical Summary

Problems solved by technology

The existing pressure point device cannot ensure that the copper material can contact the preset precision parts in the thin-walled copper tube, and requires repeated operations by workers, which increases the labor intensity of workers and reduces production efficiency

In addition, when more points are to be pressed between the two points that have been pressed, the small chuck has to be replaced or more conical heads are added between the original two conical heads to achieve Pressing multiple dots between two good points will undoubtedly further increase labor intensity and reduce production efficiency, and the accuracy of pressing points cannot be guaranteed, so it is not popularized.
