Detailed description of the invention
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
Be illustrated in figure 4 engine breathing mount pad, the state after punch forming, before bending and molding; Need, by being bent into pattern such as shown in Fig. 1-Fig. 3, to make Workpiece shaping for the state such as shown in Fig. 5-Fig. 7.
Wherein, as shown in Fig. 5-Fig. 7, workpiece is after being bent into pattern, the front and rear sides of plate body is respectively provided with two and installs journal stirrup d, journal stirrup d is installed all perpendicular to plate body downward bending for four, the left, center, right portion of plate body is respectively provided with an installing hole a, and three installing hole a are that isosceles triangle is arranged, three installing hole a are used for the installation of mount pad self admittedly.Each installing hole a is arranged circumferentially convex closure b, and upper convex closure b is in the same plane, all for developing with when installing and the bottom surface of engine.Be provided with the lower convex closure c of bar shaped between adjacent upper convex closure b, lower convex closure c and upper convex closure b is oppositely arranged.The advantage that this workpiece has is:
(1) adopt hot rolled steel plate integrated punching shaping, saved material and machine dosage widely, thus reduced manufacturing cost;
(2) convex closure is set in the position of three installing holes, rear orientation assemble is developed by the bottom surface of three upper convex closures and engine, compare traditional structure and position assembling by whole mount pad plane and engine, positioning precision is better, fits better, effectively prevents play, and the distortion in heat treatment process can be prevented, improve intensity, the fatigue failure probability produced when reducing engine vibration, prevent fracture;
(3) three installing holes are that isosceles triangle is arranged, being provided with lower convex closure between adjacent upper convex closure, is the bulk strength in order to improve mount pad equally, and ensure the steadiness after installing;
(4) under, convex closure adopts kidney-shaped bar structure, and contrary with the deformation direction of upper convex closure, is convenient to stamping Die Design, prevents the stress deformation that heat treatment produces simultaneously, improves intensity.
As Fig. 1---shown in Fig. 3, the engine breathing mount pad used is bent into pattern, is made up of upper bolster 1, cope match-plate pattern 2, die shoe 3, lower bolster 4, outer guiding mechanism 5, interior guiding mechanism 6, roller 7, mandrel 8, counterdie insert 9, counterdie pushing block 10, first return spring 11, alignment pin 12, low punch 13, jigger pin 14, upper punch 15, second return spring 16, train wheel bridge 17, upper backboard 18, lower bolster 19 and pushing block backing plate 20 etc.Cope match-plate pattern 2 is bolted on below upper bolster 1, and lower bolster 4 is bolted on above die shoe 3.
The middle part of lower bolster 4 arranges recessed groove, is provided with counterdie pushing block 10 in recessed groove, and counterdie pushing block 10 realizes floating by the first return spring 11 and installs, and can compress the first return spring 11 when namely counterdie pushing block 10 is under pressure.The forward and backward side of counterdie pushing block 10 is respectively arranged with counterdie insert 9 and about two spaced apart rollers 7, one of the corresponding bending workpieces of each roller 7 journal stirrup is installed, two rollers 7 being positioned at the same side can be sleeved on same mandrel 8 rotationally, mandrel 8 fixedly interts in each self-corresponding counterdie insert 9, counterdie insert 9 is fixed on lower bolster 4, namely two mandrels, 8, two counterdie inserts 9 and four rolling 7 is had.Three alignment pin 12, two low punches 13 for shaping workpiece under convex closure corresponding with workpiece installing hole are also housed in lower bolster 4.
Cope match-plate pattern 2 is built with the upper punch 15 of jigger pin 14 and three convex closures on shaping workpiece, and jigger pin 14 realizes floating by the second return spring 16 and installs.
Preferably, be also provided with train wheel bridge 17 and upper backboard 18 between upper bolster 1 and cope match-plate pattern 2, between die shoe 3 and lower bolster 4, be also provided with lower bolster 19.In addition, the upper end that the below of counterdie pushing block 10 is installed with pushing block backing plate 20, first return spring 11 is connected on pushing block backing plate 20.The crown center position of upper bolster 1 is also provided with die shank 21, and die shank 21 is fixed together by bolt and upper bolster 1.The first return spring 11 supporting counterdie pushing block 10 has some, to ensure counterdie pushing block 10 stress balance.
The course of work is as follows: be first placed on by workpiece on lower bolster 4, and by three alignment pins, 12 pairs of Workpiece fixing, now, the upper surface of counterdie pushing block 10 flushes with the upper surface of lower bolster 4, cope match-plate pattern 2 is descending fit with workpiece after continue steadily descending, cope match-plate pattern 2 compresses the first return spring 11 by counterdie pushing block 10, and counterdie pushing block 10 moves down, and the rotation of 7, roller, not move, thus the both sides, front and back of workpiece are made to realize 90 ° of bendings under roller 7 with the acting in conjunction of counterdie pushing block 10; Meanwhile, upper punch 15 punching press completes the upper convex closure of workpiece, and low punch 13 punching press completes the lower convex closure of workpiece; Afterwards, cope match-plate pattern 4 return, workpiece departs from cope match-plate pattern 2 under the promotion of jigger pin 14, and counterdie pushing block 10 resets, and is ejected by the workpiece after bending and molding.
