Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Shown in Fig. 4, a kind of Bending Mould of automatic demoulding, comprise upper bolster 1 and die shoe 2, the cope match-plate pattern 3 that cross section is inverted trapezoidal structure is provided with bottom upper bolster, two inclined-planes of cope match-plate pattern are provided with some dovetail grooves 4, the dovetail slide block 5 moved along dovetail groove direction is provided with in dovetail groove, dovetail slide block is connected with upper bender 6, upper bender is provided with the second inclined-plane 7 with the slopes which match of cope match-plate pattern, dovetail slide block is arranged on this second inclined-plane, dovetail shoe surface top is also provided with block 8, block is arranged in block chute 9, block chute to be arranged on bottom dovetail groove and with dovetail groove bottom through, gear hole 10 is also provided with between block chute and cope match-plate pattern, backing pin 11 is provided with in gear hole, die shoe is provided with lower bolster 12, lower bolster both sides are provided with baffle plate 13, lower bender 14 is provided with between baffle plate and lower bolster, arcwall face is set to bottom lower bender, lower bender one end is provided with stage portion 15, bottom lower bolster, side is provided with recess 16, stage portion and recesses fit are arranged, be connected by spring 17 between lower bolster with die shoe, the lateral surface of upper bender is also provided with arc fold bending portion 18, the top in arc fold bending portion is provided with right angle relief portion 19, the lower bender that arc fold bending portion is corresponding is provided with arc fold bending recess 20, arc fold bending recess is arranged on above stage portion.
Wherein, extension spring 21 is also provided with between baffle plate and lower bender.Lower bender is provided with screw 22, and described screw is connected with extension spring one end.Can remain that lower bender is to the snap of baffle plate side, the one end with stage portion then tilts, can when the demoulding, and two lower benders can not clamp finished product, and the function that realization is unclamped automatically.
Bottom upper bolster, side is also provided with pilot pin 23, for inserting location, is convenient to installation mold, location and installation position, simplifies installation difficulty.
Being provided with buffing pad 24 bottom die shoe, for having certain buffer capacity during punching press, improving service life, and when mold removal preserves placement, also as the function of mounting yoke, avoid directly contacting with ground, cause the problems such as wearing and tearing.
The angle of stage portion and recess is all set to chamfering, make precision during pressing higher, because recess in use can be descending and bear against stage portion, make lower bender be positioned at baffle plate side to tilt, so it directly affects the shape of final mould in conjunction with precision, avoid cannot clamping being combined completely because of the problem of mismachining tolerance between right angle with right angle, reduce preparation difficulty.
Backing pin one end abuts with the dovetail slide block in dovetail groove through block chute, the backing pin other end abuts with second spring 25 one end, the second spring other end abuts with lock screw 26, lock screw locking is at cope match-plate pattern top, and such backing pin can block bender portion and continue descending, and when abutting with dovetail slide block, due to the effect of spring, there is activity surplus, there is not stuck phenomenon, ensure that slip is smooth and easy.
The operation principle of the present embodiment is as follows:
During use, surface plate both sides being bent with vertical right angle kink is placed on above die shoe, as shown in Figure 1, then upper bolster is descending, first two upper benders are conflicted surface plate, upper bolster continues descending, upper bender subject plane plate cannot be descending, can only be up along dovetail groove direction, when cope match-plate pattern conflicts surface plate, upper bender is also up to dovetail groove top, namely a patrix completed is formed with cope match-plate pattern, continue descending, surface plate is pressed to lower bolster, surface plate two ends are owing to there being the existence of lower bender, so can preliminary bending be out of shape, descending when continuing after surface plate conflict lower bolster, it is descending that lower bolster two ends press against stage portion by recess, namely make lower bender be positioned at baffle plate one end to be tilted, when lower bolster overwhelms low, two lower benders and lower bolster form the counterdie of overall shape, now surface plate is also pressed into type, upper bolster starts to reset, due to gravity, when cope match-plate pattern rises, upper bender can glide along dovetail groove owing to not supporting, until block is just drawn high after abutting with backing pin, owing to being inclined-plane, after the above bender taxiway cope match-plate pattern extreme lower position of institute, the scope of the vertical right angle kink of finished product can be departed from, so can not product be caught on, while upper bolster is up, lower bolster is upspring by spring, the recess of lower bolster removes exerting pressure to stage portion, lower bender is hauled return by extension spring, by loosening of bender clamping under the lifting of lower bolster and both sides, easily product can be lifted, handled easily person easily can take out product.
The present invention can complete demoulding work automatically, simplifies workflow and reduces work difficulty, and one-shot forming, yield is high, and production efficiency is high
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
