Abstract
The invention relates to a technique for controlling quenching distortion of parts, in particular to a machining method for controlling quenching distortion of aluminum-alloy and stainless-steel multi-notch parts. The multi-notch parts are widely used in the manufacturing process of sheet metal parts, most of which have complex shapes and need to be quenched after being formed in a soft material state; no good control method is available during quenching in the prior art, the multi-notch parts are distorted seriously after being quenched, the shape-correction workload is increased, and a part of the parts which are excessively distorted cannot be corrected to a normal state. The quenching distortion of the parts is controlled in the following two ways: allowance is reserved for notches for reinforcing treatment in the blanking process of the parts; the whole periphery of each of the parts is fastened before the parts are quenched. The quenching distortion of the parts is effectively controlled through the machining method, the shape-correction workload of the parts is reduced, the labor intensity is reduced and the product quality is improved.
Description
Technical field
The present invention relates to a kind of technology of parts quenching Deformation control, be specially adapted to the working method controlling aluminium alloy, the distortion of stainless steel many breach parts quenching.
Background technology
In sheet metal part manufacturing processed; many breach part ubiquity; and major part is complex-shaped; quenching is needed after being shaped under soft material state; prior art does not have good control method when quenching, and there is gross distortion after many breach parts quenching, and school shape amount strengthens; portion parts deflection is too large, cannot return in school.
Summary of the invention
Goal of the invention
There is provided a kind of working method controlling the distortion of many breach parts quenching, there is gross distortion after solving many breach parts quenching, part deformation amount is too large, cannot the school problem of returning.
Summary of the invention
The state of described many breach part before carrying out quenching technology is soft material, and the material of many breach part is aluminium alloy, stainless steel.Many breach part shape is the U-shaped part etc. of both sides crimp, and breach is positioned at many breach part both sides crimp, gap width is less than 1/5 of part length, and its breach is positioned at many breach part both sides crimp, is uniformly distributed, and carries out following process to many breach part:
Step 1:: at blanking procedure, carries out the process of made allowance reinforcement to the breach on many breach part, and stiffening web is all left in the bottom of each breach of top and bottom, and the height of stiffening web is the over half of the height of corresponding breach;
Step 2: before many breach part send quenching, adopting metal to be wound around silk, to carry out periphery to its entirety fastening;
Step 3: many breach part quenches, routine operation;
Step 4: remove stiffening web, metal twister, affiliated metal twister is aluminium wire or copper wire.
Invention effect
The problem of larger distortion is there is after effectively solving panel beating bulkhead type parts quenching after the present invention.Quality product significantly improves, and operator's workload obviously reduces.
Accompanying drawing and brief description of drawings
Fig. 1 is many breach design of part schematic diagram;
Fig. 2 is structural representation of the present invention.
Embodiment
See Fig. 1, the state of described many breach part before carrying out quenching technology is soft material, and the material of many breach part is aluminium alloy, stainless steel.Many breach part shape is the U-shaped part etc. of both sides crimp, and breach is positioned at many breach part both sides crimp, gap width is less than 1/5 of part length, and its breach is positioned at many breach part both sides crimp, is uniformly distributed, and carries out following process to many breach part:
See Fig. 2, step 1: at blanking procedure is CNC cutting, carries out the process of made allowance reinforcement, stays the surplus of about Bending edge height 2/3 inwards during blanking at breach along crimp outer rim, shut breach outer the breach on many breach part; Stiffening web is all left in the bottom of each breach of top and bottom, and the height of stiffening web is the over half of the height of corresponding breach;
Step 2: before many breach part send quenching, adopting metal to be wound around silk, to carry out periphery to its entirety fastening;
Step 3: many breach part quenches, routine operation;
Step 4: remove stiffening web, metal twister, affiliated metal twister is aluminium wire or copper wire.
Claims (2)
1. one kind controls the working method of many breach parts quenching distortion, the state of described many breach part before carrying out quenching technology is soft material, the material of many breach part is aluminium alloy, stainless steel, many breach part shape is the U-shaped part etc. of both sides crimp, breach is positioned at many breach part both sides crimp, gap width is less than 1/5 of part length, it is characterized in that: breach is positioned at many breach part both sides crimp, is uniformly distributed, and carries out following process to many breach part:
Step 1:: at blanking procedure, carries out the process of made allowance reinforcement to the breach on many breach part, and stiffening web is all left in the bottom of each breach of top and bottom, and the height of stiffening web is the over half of the height of corresponding breach;
Step 2: before many breach part send quenching, adopting metal to be wound around silk, to carry out periphery to its entirety fastening;
Step 3: many breach part quenches, routine operation;
Step 4: remove stiffening web, metal twister.
2. a kind of working method controlling the distortion of many breach parts quenching as claimed in claim 1, is characterized in that: affiliated metal twister is aluminium wire or copper wire.
