Description
Technical field
The utility model relates to the technical field of hydraulic press.
Background technology
General traditional single action hydraulic press has only a slide block, slide block can only be finished once positive pull and stretch or a reverse drawing in one stroke, workpiece is after finishing positive pull and stretch, if need reverse drawing, just need transfer on the other hydraulic press, also need simultaneously workpiece is alignd with mould, just can carry out the operation of reverse drawing.The precision of product is low, and production efficiency is low.In the process of work, need many machines just can finish each production process, increased the cost in the production process.
The utility model content
The utility model purpose provides a kind of high efficiency, product precision height, the double action hydraulic press with compound pull and stretch function that cost is low.
The middle part of the utility model hydraulic press is provided with the pull and stretch slide block, and the upper end of pull and stretch slide block is connected with the pull and stretch cylinder, and the lower end of pull and stretch slide block is connected with the pull and stretch module; The center of pull and stretch slide block, pull and stretch module is provided with knockout rod, and the periphery of pull and stretch slide block is provided with blankholder slide, and the upper end of blankholder slide is connected with the flanging cylinder respectively, and the lower end of blankholder slide is connected with the flanging upper module respectively; Below the flanging upper module, be provided with the flanging lower module, the inboard of flanging lower module is respectively arranged with blank holder, the blank holder lower end is connected with push rod, the lower end of flanging lower module is fixed on the fuselage, the upper center of fuselage is connected with the punch corresponding with the pull and stretch module, have the through hole that is complementary with above-mentioned push rod external diameter on the fixture, described push rod passes through hole and is connected with hydraulic die cushion, and the lower end of hydraulic die cushion is connected with the hydraulic die cushion cylinder.
The utility model in use, double action hydraulic press is in original state, pull and stretch slide block, blankholder slide and hydraulic die cushion are parked in original position, workpiece is placed on the top of flanging lower module.Start double action hydraulic press, blankholder slide takes the lead in moving downward, and flanging upper module and flanging lower module carry out flanging to workpiece, pull and stretch slide block down then, and the edge of pull and stretch module carries out positive pull and stretch to workpiece.When positive pull and stretch finishes, the pull and stretch slide block continues descending, promotes hydraulic die cushion by hydraulic die cushion blank holder, push rod and moves down, and this moment, double action hydraulic press was automatically converted to the hydraulic die cushion flanging, this moment, the bottom of pull and stretch module was corresponding with punch on the fuselage, and the pull and stretch slide block carries out reverse drawing.Slide block only needs one stroke just can finish once positive pull and stretch and two operations of a reverse drawing like this, do not need to finish with workpiece shift, operation such as alignment, improved the precision of product greatly.The utility model has been realized high efficiency, product precision height, the purpose that cost is low.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of positive pull and stretch state of the present utility model.
Fig. 3 is the structural representation of reverse drawing state of the present utility model.
The specific embodiment
As shown in the figure, the middle part of hydraulic press is provided with pull and stretch slide block 5, and the upper end of pull and stretch slide block 5 is connected with pull and stretch cylinder 2, and the lower end of pull and stretch slide block 5 is connected with pull and stretch module 6; The center of pull and stretch slide block 5, pull and stretch module 6 is provided with knockout rod 16; The periphery of pull and stretch slide block 5 is respectively equipped with blankholder slide 3, and the upper end of blankholder slide 3 is connected with flanging cylinder 1, and the lower end of blankholder slide 3 is connected with flanging upper module 4; Below flanging upper module 4, be provided with flanging lower module 7, the inboard of flanging lower module 7 is provided with blank holder 8, blank holder 8 lower ends are connected with two push rod 10-1,10-2, the lower end of flanging lower module 7 is connected with fuselage 13, the upper center of fuselage 13 is connected with the punch 9 corresponding with pull and stretch slide block 5, have the through hole 12-1, the 12-2 that are complementary with push rod 10-1,10-2 external diameter on the fuselage 13, described push rod 10 passes through hole 12 and is connected with hydraulic die cushion 14, and the lower end of hydraulic die cushion 14 is connected with hydraulic die cushion cylinder 15.
In work, Fig. 1 is the original state of double action hydraulic press, and flanging upper module 4 is separated with flanging lower module 7, and workpiece 17 is placed on the top of flanging lower module 7.As shown in Figure 2, blankholder slide 3 moves downward fast under the thrust of pressure cylinder 1 workpiece 17 is carried out flanging, and it is descending that pull and stretch slide block 5 promotes pull and stretch module 6 under the effect of pull and stretch cylinder 2 at this moment, and workpiece 17 is carried out positive pull and stretch.As shown in Figure 3, pull and stretch slide block 5 promotes pull and stretch module 6 and continues descending, promotion blank holder 8, push rod 10 move downward, push rod 10-1,10-2 move along through hole 12-1,12-2, promoting hydraulic die cushion 14 simultaneously moves to the direction of compression hydraulic die cushion cylinder 16, the bottom of pull and stretch module 5 is corresponding with punch 9 at this moment, and workpiece 17 is carried out reverse drawing.Though pull and stretch slide block 5 and blankholder slide 3 move downward all the time like this, two actions of positive pull and stretch and reverse drawing in slide block stroke once, have been finished.
After workpiece 19 processed moulding, pull and stretch slide block 5 is being with workpiece 19 backhauls, also backhaul of blankholder slide 4, hydraulic die cushion 14 backhaul under the thrust of hydraulic die cushion cylinder 15 simultaneously.After being up to certain position, pull and stretch slide block 5 and blankholder slide 4 stop, knockout rod 16 downward dnockouts, and workpiece 17 falls, and pull and stretch slide block 5 and blankholder slide 4 are got back to top dead-centre.
