[0065] see figure 1 , the wrench processing integrated molding process provided in this embodiment includes:

[0066] Workpiece blank processing step S101: processing raw materials into workpiece blanks.

[0067] Forming blank processing step S102: the workpiece blank is clamped on the lathe through the spindle chuck, and a smooth forming blank for cold extrusion processing is obtained by turning.

[0068] Forming step S103: Put the forming blank into the mold, and obtain an integrally formed product through cold extrusion processing.

[0069] In this embodiment, the method of processing raw materials into workpiece blanks is an existing technology, which can be obtained by forging and pressing methods, and the shape of the workpiece blanks is elongated. In this way, the mold and process of forging the workpiece blank are simpler and the cost is reduced.

[0070] see figure 2 , in this embodiment, the spindle chuck includes an adjustment base 101 installed on a lathe. Th...

[0079] see image 3 , the wrench processing integrated molding process provided by this embodiment has the same principle and technical effect as the first embodiment. For a brief description, for the part not mentioned in this embodiment, you can refer to the corresponding content in the first embodiment . The wrench processing integrated molding process provided in this embodiment can be used to process various types of wrenches. The process, principle and technical effect of the process will be described in detail below by taking the processing of ratchet wrenches as an example:

[0080] see image 3 , in this embodiment, the forming blank processing step S102 includes a rough processing step S1021 and a finishing step S1022.

[0081] Specifically, the rough machining step S1021: the workpiece blank is clamped on the lathe by the spindle chuck, and the workpiece blank is rough-turned.

[0082] Finishing step S1022: the rough-machined workpiece blank is clamped by the spi...

Abstract

The invention provides a wrench machining integrated forming process, and belongs to the technical field of wrench machining. The process comprises a workpiece blank machining step of machining a raw material into a workpiece blank, a formed blank machining step of clamping the workpiece blank on a lathe through a main shaft chuck to obtain a smooth formed blank for cold extrusion machining through turning and a forming step of placing the formed blank into a mold to obtain an integrally formed product through the cold extrusion machining. According to the wrench machining integrated forming process, the machining size control is more accurate, the appearance of the product is consistent, the machining error is small, processes such as polishing and grinding are saved, the machining efficiency is greatly improved, and the machining cost is reduced.

Description

technical field [0001] The invention relates to the technical field of wrench processing, in particular to an integral forming process for wrench processing. Background technique [0002] At present, wrenches are usually processed by forging and pressing. The products obtained by forging and pressing are difficult to control the processing size and have large tolerances. The products need to be processed separately by hand. The processing efficiency is low, which affects the subsequent processing, and the surface roughness of the product is high. Manual polishing is required to achieve the mirror effect, which is time-consuming and costly. The mirror texture is not beautiful, and it is difficult to achieve consistent product appearance in mass production. Contents of the invention [0003] The present invention provides a wrench processing integrated forming process, aiming to improve the above problems. [0004] The present invention is achieved like this: [0005] An i...
