Problems solved by technology

[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 the same product appearance in mass production.

Embodiment Construction

[0011] The specific embodiment of the present invention is described further below:

[0012] An adjustable wrench processing technology is characterized in that it comprises the following steps:

[0013] (1) Workpiece blank processing: process raw materials into workpiece blanks;

[0014] (2) Forming blank processing: 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;

[0015] (3) Forming: Put the forming blank into the mold, and obtain an integrally formed product through cold extrusion processing;

[0016] (4) Polishing: Put the integrally formed product into a polishing machine for polishing.

[0017] What described in above-mentioned embodiment and description only illustrates the principle and preferred embodiment of the present invention, under the premise of not departing from the spirit and scope of the present invention, the present invention also can have various ch...

Abstract

The invention relates to the technical field of spanner machining, in particular to an adjustable spanner machining technology. The adjustable spanner machining technology comprises the following steps of workpiece blank machining, formed blank machining, forming and polishing. A formed blank with the dimensional accuracy and surface roughness meeting the product requirements is obtained through turning machining, then an integrally formed product is obtained through cold extrusion machining, size control is more precise, the appearance of the product is consistent, the machining error is small, the processes of polishing, grinding and the like are omitted, the machining efficiency is greatly improved, and the machining cost is lowered.
