Abstract
The invention relates to the invention of Scrapless shaping die making multipiece used in holes.The present invention is being rolled into the block ring blank that a circle connects a circle, cover has the axle outside of groove in the above, with cutting off the press-bending cutter, block ring blank to the groove place is exerted pressure, make its cut-out become a plurality of circlip for holes, because operating efficiency and utilization rate of raw materials are all very high, so the circlip for hole cost of producing is very low, have very big potential market.Be indispensable mould of the big enterprise of back-up ring factory and back-up ring requirement and indispensable manufacture method.
Description
The invention relates to the invention of circlip for hole finishing die, particularly Scrapless shaping die making multipiece used in holes.
Circlip for hole is the indispensable parts of electromechanical industries, applied range, requirement is big, various vehicles, power, lathe, agricultural machinery, water pump, blower fan, sprayer etc. are all used circlip for hole, but in the production of circlip for hole, still exist some problems, with regard to the circlip for hole of making by steel wire commonly used, its production process generally is rolled into block ring blank with steel wire, cut off again, bending forming singly then, its shortcoming labour intensity is big, inefficiency, advantage is, equipment is simple, reduced investment, utilization rate of raw materials height.Another kind is the circlip for hole that sheet material is made, and its production method is to utilize blanking die stamping-out and obtain circlip for hole on sheet material, and its advantage is that high efficiency, shortcoming are that utilization rate of raw materials is low, the cost height.
The objective of the invention is to have the mould of the high advantage of panel back-up ring efficient again and utilize this mould to make the method for circlip for hole for a kind of advantage that had both had system elastic spring material saving is provided.
The present invention is rolled into the block ring blank that a circle is close to a circle to internal diameter by the product tolerance, cover on top has the axle outside of groove, with the cut-out press-bending cutter of a both sides symmetry the full gear at groove place being enclosed base exerts pressure, block ring blank is cut off, continue to press inward, cut full row's block ring blank has just become a plurality of circlip for holes again.1. the shape of circlip for hole and forming process see accompanying drawing 1; 2.; 3.; 4.; 5..
The shape of axle adopts flat key keyway type easy to manufacture.Also can be according to the steel wire diameter of circlip for hole, back-up ring internal diameter and steel wire elasticity are made inclination to the trench wall of axle.
Compared with the prior art the present invention has simplified manufacturing technique, shortens the production cycle, guarantees product quality, and economical with materials and energy resource consumption reduce labor intensity, and characteristics such as the environmental pollution of minimizing are arranged, and is beneficial to production by row and quota management.Corrected people and thought spring steel wire hardness height for a long time, elasticity is big, utilizes the mould prejudice of many difficulties that are shaped fast, has solved people and has thirsted for for a long time solving, but not have the technical problem of breakthrough all the time.
Accompanying drawing has been described one embodiment of the present of invention.
Accompanying drawing 1: the 1. shape of circlip for hole, the shape before 2. block ring blank is enclosed within and does not exert pressure on the axle, 3. cutting-off process, 4. the shape behind the press shaping die wraps in the shape on the axle after 5. being shaped.
Accompanying drawing 2 is planforms of Scrapless shaping die making multipiece used in holes, and axle that a top has a groove is adorned in the middle part of this finishing die 10., so that will be rolled into block ring blank cover that a circle is close to a circle outside.At the cut-out press-bending cutter that a both sides symmetry is arranged facing to the top of axle groove 5., under the press effect, cut off the press-bending cutter and 5. block ring blank is exerted pressure, it is cut off bend until shaping.Cut off the press-bending cutter and 5. be fixed in the fixed head groove 7. with holding screw, fixed head 7. with straight pin and soket head cap screw be fastened on cope match-plate pattern 4. below.
In order to make steel wire distortion regularly in cutting-off process, respectively adorn a moving jaw 8. in axle both sides 10., moving jaw has elongated slot on 8., being fixed on die holder versatilely with stop screw 1. goes up, power screw is housed in the moving jaw outside 8. and adjusts pad, so that the clamping force during with mold work is adjusted to optimum position, moving jaw clamping 8. is to be close to fix on the scarce round wedge of cope match-plate pattern in 4. and 3. drive, 3. scarce circle is exactly the cam that moves as linear reciprocation, be contained in moving jaw 8. the outside power screw be exactly the driven push rod of translating cam mechanism.Moving jaw unclamping 8. is to be fixed on die holder by an end 1. to go up, and the other end is fixed on that the tension spring (12) in the moving jaw outside finishes.
To lack the circle wedge and 3. when descending, can locate exactly in order to make, facing to lack the circle wedge 3. the die holder in the outside guide pad is housed 2. on 1., 2. guide pad is fixed on die holder with straight pin and screw and 1. goes up.
Seated feather key (11) is provided with for 10. the axle that is with block ring blank has good location before work, and seated feather key (11) is fixed on die holder with straight pin and screw and 1. goes up.
6. whole secondary mould is contained on the press by die shank.
Claims (2)
1, many finishing dies of a kind of circlip for hole are made up of upper die and lower die, it is characterized by:
A, counterdie are one and can insert in the good block ring blank of coiling, have the axle of groove, but the finishing die of above-mentioned groove dimensions double as back-up ring.
B, patrix are one and cut off the press-bending cutter.
C, be contained in the axle both sides in addition, be used for clamping the movable mismatch of block ring blank.
2, utilize this mould directly to make the method for circlip for hole.
