Abstract
The invention relates to a spring production process flow for increasing the frequency of load detection, in particular to a process flow for increasing the frequency of load detection in a spring production process flow in order to raise the qualified rate of spring products. The process flow comprises the following procedures of coiling a spring blank so as to form a semi-finished spring; tempering the semi-finished spring; shot-blasting the semi-finished spring; compressing the semi-finished spring; detecting the load of the semi-finished spring for the first time; treating the surface of the semi-finished spring so as to form a spring product; detecting the load of the spring product for the second time; and packaging the spring product. As length detection is changed into load detection before a spring surface treatment procedure in the prior art, the frequency of spring load detection can be increased by once, and then small cost needs to be increased even if the spring with unqualified load is reworked. Therefore, the process flow can greatly reduce the cost of spring production.
Description
Technical field
The present invention relates to the technological process that a kind of spring is produced, referring in particular to increases load detection times to improve a kind of technology of spring product up-to-standard rate in the technological process that spring is produced.
Background technique
Whether qualified the load of spring product be quality index the important parameter of detection springs product, therefore, in the technological process that traditional spring is produced, always is that the operation that load detects is placed on last procedure before the packing of product.
Referring to Fig. 1, Fig. 1 is traditional spring production process flow figure, by diagram as can be known, and the technological process that traditional spring is produced:
Blank of spring carries out wind spring → tempering → shot-peening → compression → length detection → surface treatment → load detection → packing of product.
In the above-mentioned tratitional technology, less to some load tolerances, the bigger spring of rigidity is because of generation power is big or power is little easily situation, therefore in the operation of length detection, some underproof semi-finished product springs of loading are easy to be taken as qualified spring, find that just the load parameter of these products is defective during operation that to the last product load detects, therefore, the up-to-standard rate of product is lower, and this moment, spring has flow to after the surface treatment procedure, do over again, just need remove spring surface paint again after, begin to continue again all process steps in road after a time again from blasting process, manually, Material Cost is higher.
Summary of the invention
The objective of the invention is in order to solve the problem that prior art exists, a kind of up-to-standard rate that improves spring product is provided, reduces the spring production process flow of the increase load detection times of spring cost of production
The object of the present invention is achieved like this:
A kind of spring production process flow of load detection times comprises following operation:
Blank of spring carries out wind spring, becomes the operation of semi-finished product spring;
Above-mentioned semi-finished product spring is carried out the operation of temper;
Above-mentioned semi-finished product spring is carried out the operation of shot-peening;
The operation that above-mentioned semi-finished product spring is compressed;
Above-mentioned semi-finished product spring is carried out the operation of load detection for the first time;
Above-mentioned semi-finished product spring is carried out surface treatment, become the operation of spring product;
Above-mentioned spring product is carried out the operation of load detection for the second time;
The operation that spring product is packed.
Effect of the present invention:
Detect owing to before the spring surface treatment procedure of tratitional technology, changing length detection into load in the spring production process flow of increase load detection times of the present invention, can increase the number of times of a spring-load detection like this, underproof spring is done over again even will load this moment, do not increase too big cost yet, can significantly reduce the cost of producing spring.
For further specifying above-mentioned purpose of the present invention, structural feature and effect, the present invention is described in detail below with reference to accompanying drawing.
Description of drawings
Fig. 1 is traditional spring production process flow figure;
Fig. 2 is spring production process flow figure of the present invention;
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the spring production process flow of increase load detection times of the present invention is elaborated.
Referring to Fig. 2, Fig. 2 is spring production process flow figure of the present invention, by diagram as can be known, and the technological process that spring of the present invention is produced:
Blank of spring carries out the wind spring → tempering → shot-peening → compression → load detection → surface treatment first time → detection → packing of loading the second time.
The spring production process flow that is load detection times of the present invention comprises following operation:
Blank of spring carries out wind spring, becomes the operation of semi-finished product spring;
Above-mentioned semi-finished product spring is carried out the operation of temper;
Above-mentioned semi-finished product spring is carried out the operation of shot-peening;
The operation that above-mentioned semi-finished product spring is compressed;
Above-mentioned semi-finished product spring is carried out the operation of load detection for the first time;
Above-mentioned semi-finished product spring is carried out surface treatment, become the operation of spring product;
Above-mentioned spring product is carried out the operation of load detection for the second time;
The operation that spring product is packed.
In the technology of the present invention, change compression section in the tratitional technology and the length detection technology between the surface treatment procedure into operation that increase is once loaded and detected.
Technological process of the present invention can directly detect once load earlier behind compression section, elder generation eliminates the underproof semi-finished product spring of load parameter or does over again in this procedure, just can reduce at the underproof product of packing of product preload, even do over again this moment, cost is not high yet, greatly reduces the cost of producing spring.
In traditional spring production process flow, the rework rate the when load before the packing of product detects is the 1/3-1/2 of bulk article.And in the spring production process flow of the present invention behind the number of times that increases the spring-load detection, the rework rate the when second time before the packing of product, load detected only is 1/5 of a bulk article.And such effect is to have increased the number of times that spring-load detects in the technological process of the present invention directly to cause.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating purpose of the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claims of the present invention the above embodiment's variation, modification.
