AI Technical Summary

Problems solved by technology

The existing puller is made by welding, so it can bear less stress, and the puller is easy to break at the weld, causing the steel bar to break and causing accidents.
[0004] The existing puller is composed of four components, and the sheet body 3 and the cylinder 1 must have a certain thickness before they can be implemented. Therefore, the amount of material used is large, resulting in heavy weight and increased cost. The re-welding of sheet body 3 and cylinder 1 will increase the production time and slow down the production process

Embodiment Construction

[0029] Regarding the technology, means and effects used in the present invention, a preferred embodiment is given and described in detail below with drawings, which are for illustration purposes only, and are not limited by this structure in the patent application.

[0030] refer to figure 1 , is a block flow chart of the present invention. Its steps of the manufacture method of puller 10 of the present invention are as follows:

[0031] The first step - material preparation (refer to figure 2 ): Prepare a metal blank 20 of the puller 10. Generally, metal materials are in the form of ingots or sheets after being melted and smelted. Prepare this raw material and cut it to the required size.

[0032] The second step—deep drawing convex portion 30 (refer to image 3 and Figure 4 ): Deep drawing is a technical method belonging to the drawing method. The raw material is heated to the forging temperature, the raw material is placed on the deep drawing table, and the punch i...

Abstract

The invention relates to a method for manufacturing a seamless puller with one piece, which is to form a single metal blank through deep drawing to form two convex parts, and repeatedly deep draw the two convex parts to form two ends, and then draw the two convex parts on the metal blank. Deep drawing is carried out on one side, and a depression is formed through repeated deep drawing through the continuous mold, and the depression is penetrated to form a hole, and then a perforation is pierced at the convex part, and a thread is tapped.

Description

technical field [0001] The invention relates to the field of pullers, in particular to a method for manufacturing an integrally formed seamless puller. Background technique [0002] Generally, pullers are often used for construction sites or other various purposes. The pullers can be tightly screwed by using the open ends at both ends of the pullers to pass through threaded steel bars at the same time, so as to facilitate their transportation, transmission or combination. And the transportation industry can be said to be quite practical. [0003] Please refer to Figure 11 , is a schematic diagram of the existing puller. The existing puller is provided with two hollow cylinders 1, and threaded with thread 2, and the two hollow cylinders 1 are connected by welding two pieces 3. The existing puller is made by welding, so the stress it can withstand is small, and the puller is prone to breakage at the welding point, which causes the steel bar to break and accidents to happen....
