Problems solved by technology

[0004] 1. Using the rolling method to form the gripping part 11 of the shape is not only difficult to master because of the force, but also more likely to cause deformation that is difficult to control and has a large tolerance
[0005] 2. The I-shaped grip part 11 of the so-called I-shaped wrench is not only set as a grip part with the same thickness, but also may have a structural design with a gradually increasing thickness, as shown in Figure 3, so the above-mentioned force and The amount of deformation is more difficult to control
[0006] 3. The surface of the grip formed by roll forming cannot be completely smooth, so the comfort in the grip is different, which will cause discomfort in the grip
[0008] In order to solve the problems existing in the manufacturing method of the I-shaped wrench, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable manufacturing method has been developed, and there is no suitable method for the general manufacturing method. To solve the above problems, this is obviously a problem that the relevant industry is eager to solve

Embodiment Construction

[0038] The specific manufacturing method, steps, features and effects of the manufacturing method of the work wrench according to the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0039] Please refer to Fig. 4 and shown in Fig. 5, the manufacturing method of the work wrench of the present invention mainly comprises the following process steps:

[0040] 1. Forging for the first time: using hot forging to forge a rough blank wrench with an I-shaped grip part 21. At this time, the rough blank wrench has a relatively rough shape of the I-shaped grip part;

[0041] 2. The second forging: the rough blank wrench that was hot forged for the first time is forged for the second time, and the fine blank wrench 22 is forged using a warm forging method that is lower in temperature than the first forging. The second warm forging method is used for forging, so the forged fine blank wrench 22 can have better dimens...

Abstract

A technology for manufacturing H-shaped spanner includes such steps as forging to obtain the raw blank of H-shape spanner with H-shaped handle, forging again to obtain the fine blank, and grinding. Its advantages are simple process and precise sizes.

Description

technical field [0001] The invention relates to a manufacturing method of a wrench used in tools for fastening, connecting, dismounting, or clamping in the field of hand tools, in particular to a manufacturing method of an I-shaped wrench capable of simply manufacturing an I-shaped grip. It uses the first and second forging methods at different temperatures, combined with the detailed processing steps, which can make the production process of the work wrench easier and the tolerance can be smaller, so that it is more in line with the needs of the industry, and The thickness of the work wrench can be controlled more easily and more accurately, and has industrial utilization value, and then becomes a quite practical and progressive new design, which is suitable for wide application in the industry. Background technique [0002] Please refer to FIG. 1 , which is a schematic structural view of a conventionally used I-shaped wrench. The structure of the current general I-shaped ...
