Description
Technical field
The present invention relates to a kind of elongated lock pressing mold frock anti-deformation processing method, for processing the frock of elongated many surface-type features.
Background technology
At present, general category lock pressing mold frock length is usually no more than 800mm, and during processing, deflection is little, and profile tolerance is easily controlled, and clamping is simple and convenient.And for elongated lock pressing mold frock length at more than 800mm, the situation that profile is narrow and profile is more, the widest the longest ratio of this frock general is more than 10:1, add man-hour, owing to its bottom surface is too small, be difficult to direct clamping, if directly processing this frock, there is moderate finite deformation amount in this frock end face cusp end, the clamping groove bottom this frock follow-up also cannot be processed by clamping, it is difficult to ensure that the size of this frock drawing requirement and precision.If taking turn-over to process, owing to the long centre of frock positions without the strong point during turn-over second time processing profile, adding and can deform equally man-hour, therefore, the production and processing for this elongated lock pressing mold frock has very big difficulty.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of elongated lock pressing mold frock anti-deformation processing method, the method adopts supplement art cushion block and supports the numerical-control processing method of cylinder, when making this work clamping process, structure is more stable, there is positioning datum and clamping face accurately, can quick-clamping, and add Stability Analysis of Structures in man-hour, ensure that processing profile is connected smooth nothing and connects tool marks, reduce the machining deformation amount of frock to greatest extent, ensure drawing requirement size and machining accuracy, improve production efficiency and crudy.
The technical solution used in the present invention is:
A kind of elongated lock pressing mold frock anti-deformation processing method, comprises the steps:
1) change lock pressing mold frock digital-to-analogue, by lock pressing mold frock two ends supplement art cushion block, elongated face I is added support cylinder, and determines lock pressing mold frock woollen size according to digital-to-analogue size；
2) planing operation, the black oxide coating of lock pressing mold frock woollen removed by planer；
3) lock pressing mold frock is carried out grinding；
4) pressing plate is pressed in technique cushion block place；
5) numerical control roughing elongated face I, support cylinder, be positioned at technique cushion block and the work notch of elongated face I homonymy, and at technique cushion block place reference holes；
6) the elongated face II that turn-over numerical control roughing opposes with elongated face I, and it is positioned at technique cushion block and the work notch of elongated face II homonymy；
7) lock pressing mold frock is carried out heat treatment, destressing；
8) numerical control roughing is removed and is supported cylinder；
9) numerical control polish lock pressing mold frock, stays polishing surplus 0.03-0.05mm；
10) the lock each profile of pressing mold frock is measured by datum hole；
11), after satisfactory lock pressing mold frock being carried out each profile polishing, technique cushion block is removed.
Described processing method, step 2) each profile of planing operation stays allowance 0.6-0.8mm.
Described processing method, step 3) grinding, mill elongated face I is parallel with elongated face II, and the depth of parallelism is 0.02-0.05mm.
Described processing method, step 5) processing elongated face I stays allowance 3.5-5.0mm；Step 6) processing elongated face II stay allowance 3.5-5.0mm.
Described processing method, step 7) it is specially lock pressing mold frock is placed in shaft furnace, after furnace temperature is risen to 680-700 DEG C, body of heater natural cooling, takes out.
Described processing method, step 1) change lock pressing mold frock digital-to-analogue, after first the two ends of lock pressing mold frock being increased 10-20mm respectively, then supplement art cushion block.
Described processing method, step 7) lock pressing mold frock is carried out heat treatment, after destressing, if lock pressing mold frock produces local deformation, need pincers worker to smooth.
Described processing method, the length and width thickness rate example of described lock pressing mold frock is 40-50:4-5:1.
The method have the advantages that
null1、The present invention adopts the two ends supplement art cushion block (after preferably two ends being lengthened respectively on the basis of original lock pressing mold frock digital-to-analogue again supplement art cushion block) in original lock pressing mold frock digital-to-analogue，The structural design supporting cylinder is added in profile side，And on the technique cushion block added reference holes，Clamping adds to be pressed in by pressing plate man-hour adds part，Follow procedure first to add support cylinder one side region carry out roughing，Reference holes，Process a rear flank turn-over clamping，By datum hole again centering, opposite side is carried out roughing，Because supporting cylinder effect，After turn-over, clamping processing will not occur bending and deformation，Overturn after processing and carry out clamping centering as bottom surface by long straight sided，Removal carries out polish after adding support cylinder，Because datum hole and supplement art cushion block are not changed in，Ensure that three machining benchmarks are constant，Thereby ensure that precision and the product quality of processing，Finally remove supplement art block portion.The method simple and fast, clamping adds Stability Analysis of Structures in man-hour, there is positioning reference plane and clamping face accurately, quick-clamping, and processing profile is connected smooth nothing and connects tool marks, reduce lock pressing mold frock machining deformation amount to greatest extent, make the lock pressing mold frock compound drawing requirement after processing and ensure machining accuracy, improve production efficiency and crudy.
2 processed by the method after lock pressing mold frock through five-coordinate measuring machine measure, frock molding surface size tolerance is all in the margin of tolerance of drawing requirement, it does not have overproof deformation, meet hand over inspection require and use needs.The method convenient mounting and clamping, digital control processing is simple, effectively prevents lock pressing mold frock machining deformation, improves this type of frock conforming product rate and machining accuracy, improves production efficiency.
