Abstract
The invention discloses a workpiece processing method which includes the following steps: (1) a punch is adopted to mold raw materials to be a tubular part; (2) anti-carburizing paints are coated on the upper portion of the tubular part; (3) a quenching device is used for quenching; and (4) a curling machine is adopted to curl edges for the upper portion of the tubular part to obtain a workpiece. The anti-carburizing paint coating procedure replaces the copper plating procedure so as to prevent the upper portion of the tubular part from being poor in edge curling caused by the fact that the upper portion of the tubular part is hard. The anti-carburizing paints are inexpensive and do not pollute the environment, and the anti-carburizing paint coating operation is simple and short in cycle, so that the workpiece processing method has the advantages of meeting environment protection requirements, being short in processing cycle and high in productivity, and reducing production cost.
Description
Technical field
The present invention relates to a kind of processing method of the workpiece for automobile.
Background technology
With reference to figure 1 and Fig. 2, a kind of workpiece that is used for automobile comprises body 1 and crimping 2, and crimping 2 is positioned at the top of body 1.In order to satisfy the client to the requirement of workpiece hardness, workpiece all needs to carry out Quenching Treatment.This workpiece all is to adopt first stamping machine that the raw material punching press is tubular elements usually; Crimping processing need to be carried out in tubular elements top, low in order to prevent that tubular elements top from rewinding limit operation yield under heat treatment time sclerosis causes, before heat-treating, usually will be in the copper facing of the top of tubular elements in case carburizing, after finishing heat treatment, again crimping processing is carried out on tubular elements top, namely made this workpiece.This processing technology following points that mainly had problems: (1) is present, and the price of copper is higher, causes high cost; (2) be difficult for meet the requirement of environmental protection, processing cost is high.(3) process-cycle long, productivity ratio is low.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of processing method of workpiece, satisfy to reach that environmental requirement, process-cycle are short, high productivity, and reduce production costs purpose.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of processing method of workpiece comprises the steps:
(1), adopt stamping machine that raw material are shaped to tubular elements;
(2), masking paste is coated on tubular elements top;
(3), adopt quenching unit to carry out Quenching Treatment;
(4), adopt crimping machine that crimping is carried out on shape spare top, namely make workpiece.
By technique scheme, the processing method of a kind of workpiece provided by the invention is coated with the masking paste operation by employing and replaces the copper facing operation, to prevent that tubular elements top is because firmly causing crimping bad; Because masking paste is more cheap, and it is simple and the cycle short to be coated with the masking paste Comparision, and masking paste does not pollute the environment, the environmental requirement of satisfying, process-cycle are short so the processing method of this workpiece provided by the invention has, high productivity, and reduce production costs advantage.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art.
Fig. 1 is the front view of workpiece;
Fig. 2 is the top view of workpiece.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described.
The processing method of a kind of workpiece provided by the present invention comprises the steps:
(1), adopt stamping machine that raw material are shaped to tubular elements;
(2), masking paste is coated on tubular elements top;
(3), adopt quenching unit to carry out Quenching Treatment;
(4), adopt crimping machine that crimping is carried out on shape spare top, namely make workpiece.
Be coated with the masking paste operation by employing and replace the copper facing operation, to prevent that tubular elements top is because firmly causing crimping bad; Because masking paste is more cheap, and it is simple and the cycle short to be coated with the masking paste Comparision, and masking paste does not pollute the environment, the environmental requirement of satisfying, process-cycle are short so the processing method of this workpiece provided by the invention has, high productivity, and reduce production costs advantage.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (1)
1. the processing method of a workpiece is characterized in that, comprises the steps:
(1) adopt stamping machine that raw material are shaped to tubular elements;
(2) masking paste is coated on tubular elements top;
