Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy extrusion tool technology, specifically a perforated needle structure that improves loading and unloading strength. Background Technology

[0002] The distance between the currently used perforated needle removal wrench latch and the copper sleeve fixing position and the end of the perforated needle is relatively close (e.g.) Figure 1 As shown in the figure, when installing the perforating needle, because the distance between the perforating needle removal wrench position and the copper sleeve fixing position and the end of the perforating needle is relatively close, the front end fixing cap of the extrusion rod needs to be removed before the copper sleeve can be installed, and then the perforating needle can be installed. After the perforating needle is installed, the front end fixing cap of the extrusion rod also needs to be installed.

[0003] However, in the existing perforation needle, workers need to disassemble and install the fixed extrusion cap at the front end of the extrusion rod during the entire installation and use process, which increases the labor intensity of workers. In addition, because the copper sleeve is fixed at the rear, the suspended part of the front end of the perforation needle is relatively long, which will have a certain impact on the wall thickness deviation of the extruded pipe. Therefore, a perforation needle structure that improves the loading and unloading strength is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of workers needing to disassemble and install the fixed extrusion cap at the front end of the extrusion rod during the entire installation and use process of existing perforation needles, which increases the labor intensity of workers, and the fact that the copper sleeve is fixed at the rear and the front end of the perforation needle is suspended for a long time, which has a certain impact on the wall thickness deviation of the extruded pipe, this utility model proposes a perforation needle structure that improves the loading and unloading strength.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the perforated needle structure for improving loading and unloading strength according to this utility model includes a perforated needle body, the perforated needle body includes a tail thread, a wrench jaw part, a copper sleeve fixing position, a working part and an internal thread.

[0006] The tail thread, wrench jaw, copper sleeve fixing position, working part and internal thread are arranged sequentially from left to right on the piercing needle body. The tail thread is located on the outer surface of the piercing needle body, the internal thread is located inside the piercing needle body, and one side of the internal thread extends to the outside of the piercing needle body.

[0007] Preferably, the wrench jaw is configured in a square shape.

[0008] Preferably, the copper sleeve fixing position is set in a circular shape.

[0009] Preferably, it also includes a cutting end, which is disposed on the right side of the piercing needle body and is integrally formed with the piercing needle body.

[0010] Preferably, the through-cutting end includes a through hole, a through-cutting surface, and a cutting surface. The cutting surface is located on the right side of the outer surface of the through-cutting end. The through hole is opened inside the through-cutting end and communicates with the interior of the internal thread. A through-cutting surface is provided on one side of the through hole.

[0011] Preferably, the cutting surface is configured in a conical shape.

[0012] Preferably, the cutting surface is chamfered.

[0013] The advantages of this utility model are:
