Abstract
The invention relates to a deformation controlling method for machining a double-side multi-rib structural part. The method comprises the following steps of: 1) clamping a part blank by adopting a tool; 2) milling a single side reference till a new metal inner layer appears; 3) turning over the part, and clamping the part by using vacuum adsorption and an external tool; 4) machining a web plate and a lateral surface on the front side, and reserving low allowance or directly machining in place, wherein ribs are not machined in height; 5) removing the vacuum adsorption and the external tool, and removing the deformation of the upper surface part in a natural state; 6) turning over and then clamping the part by using the vacuum adsorption and the external tool again, and performing rough machining and finish machining on the reverse side sequentially till the size of the part is achieved; and 7) turning over again, clamping the part by using the vacuum adsorption and the external tool, milling the ribs on the front side until the height is appropriate, and performing finish machining till the size of the part is achieved. According to the method, the deformation of the part is controlled by adopting an internal stress counteraction method in the part machining process, so that the machining period is shortened, and the quality of the part is improved.
Description
Technical field
The present invention relates to the deformation control method in a kind of two-sided many muscle constitutional detail processing, belong to field of machining.
Background technology
Deformation technique method in the two-sided many muscle constitutional detail processing of former control mainly is divided into two kinds:
1) repeatedly the turn-over method for processing is: two-sided mill benchmark after; Through roughing-turn-over-roughing-turn-over-semifinishing-turn-over-semifinishing-turn-over-fine finishining-turn-over-fine finishining; Turn-over is so repeatedly removed the method for surplus and is removed part deformation; Behind each turn-over, adopt outside clamping force to offset part deformation.Its shortcoming is: repeatedly the maximum deficiency of turn-over processing is that the process-cycle is long, and labor strength is excessive, needs to confirm again machining benchmark behind each turn-over, so also increases the difficulty of part quality control;
2) remove part deformation through the method for part processing post-equalization, promptly this takes the circumstances into consideration to increase correcting process or uses frock in middle operation the complexity of part.Its shortcoming is: method of correcting is that the method for outside stress application is removed distortion, and this method seriously influences the internal material institutional framework of part, and crackle appears in regular meeting in the trimming process simultaneously, and the situation of unbalanced stress has a strong impact on the product quality of part.
Summary of the invention
The technical problem that the present invention will solve provides the deformation control method in a kind of two-sided many muscle constitutional detail processing; This method adopts the distortion of the method control part that internal stress is offset in the part processing process; Not only shorten the process-cycle, and improved product quality.
For overcoming the above problems, concrete technical scheme of the present invention is following: the deformation control method in a kind of two-sided many muscle constitutional detail processing may further comprise the steps:
1) adopt frock that part blank is carried out clamping;
2) milling single face benchmark sees that new metal internal layer gets final product;
3) with the part upset, part is carried out clamping with vacuum suction and outside frock;
4) positive processing web and side are stayed less surplus or are machined directly to the position, and the muscle height is not processed;
5) remove vacuum suction and outside frock, remove the deflection of upper surface part under the nature;
6) once more part is carried out clamping with vacuum suction and outside frock behind the turn-over, reverse side is carried out roughing, fine finishining successively up to being worked into accessory size;
7) turn-over once more carries out clamping with vacuum suction and outside frock to part, and the positive gluten height of milling puts in place, and is finish-machined to accessory size.
Deformation control method in this two-sided many muscle constitutional detail processing adopts above-mentioned steps, the two-sided processing internal stress of part is offseted, thereby reduce the turn-over number of times of part, shortens the process-cycle of part greatly, reduces working strength of workers; Reorientate through minimizing, reaffirm the number of times of machining benchmark, improve the controllability of part quality, improve part quality.

The specific embodiment
Deformation control method in a kind of two-sided many muscle constitutional detail processing may further comprise the steps:
1) adopt frock that part blank is carried out clamping;
2) milling single face benchmark sees that new metal internal layer gets final product;
3) with the part upset, part is carried out clamping with vacuum suction and outside frock;
4) positive processing web and side are stayed less surplus or are machined directly to the position, and the muscle height is not processed;
5) remove vacuum suction and outside frock, as shown in Figure 1, the deflection 1 of removal upper surface part under the nature;
6) once more part is carried out clamping with vacuum suction and outside frock behind the turn-over, reverse side is carried out roughing, fine finishining successively up to being worked into accessory size;
7) turn-over once more carries out clamping with vacuum suction and outside frock to part, and the positive gluten height of milling puts in place, and is finish-machined to accessory size, and is as shown in Figure 2.
This method is with respect to the traditional handicraft method, and its advantage is mainly reflected in:
1) can well control processing and the payment difficulty that part deformation brings through the method;
2) through reducing the turn-over number of times of part, shorten the process-cycle of part greatly, reduce working strength of workers;
3) reorientate through minimizing, reaffirm the number of times of machining benchmark, improve the controllability of part quality, improve part quality;
4) reduce the use of correcting process, can avoid the part material disorganization that brings because of correction, also reduced the labour's loss that brings because of correcting process;
5) can reduce the quantity that frock is used after use the method, so just save the expense that frock design, manufacturing, transportation and storage etc. are brought.
