The specific embodiment

For further understanding summary of the invention characteristics of the present utility model and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1, Fig. 2.

As shown in Figure 1: be fixed with top board 2 in the casing of frame 1, on fixing on it, two horizontal rows are listed as equidistant push rod 3 down, the centre welding fixed muffle of top board 2, putting the bearing other end in one end is threaded with leading screw 4, top board 2 the bottom have two with the corresponding groove of slideway 5 sizes, during leading screw 4 motions, driving top board 2 slides along slideway 5, be set with three gripper shoes 6 on the leading screw 4, they are equidistant each other with chain 7 connections, to keep three gripper shoes, 6 distances to equate, gripper shoe 6 bottom slot cards are on slideway 5, the two ends of frame 1 are fixed with A limit switch 8 and B limit switch 23 respectively, frame 1 connects that end band contact 10 of forming tank 9, on, down two horizontal row row push rods 3 pass from the side of frame 1 and enter forming tank 9, and the end of push rod 3 has one section screw thread, put manganese steel extrusion die 11 of the band tip as shown in Figure 2 outside it, be fastened on the end of push rod 3 again with nut 12; Forming tank 9 minutes is upper and lower two-layer and link into an integrated entity with support 1, upper and lower two-layer former and later two

fixed heads

13,14 that is welded with respectively of forming tank 9, they are made up of measure-alike steel plate respectively, wherein perforate, and its height and position is aimed at push rod 3, the size in hole is bigger slightly than push rod 3 diameters, have vertical elongated slot on another piece, and two steel plates are welded together, they are staggered relatively and be welded in the forming tank 9, processed workpiece 21 can be taken out in vertical elongated slot; Transmission device: it is made of motor 15, belt transmission 16, worm reduction box 17, they all are fixed on a side of support 1, motor 15 is fixed on the steel plate 18, steel plate 18 is connected with the lateral hinges of support 1, and the top of worm reduction box 17 is welded with vertical screw rod 19, is screwed with nut 20 on it, the other end of screw rod 19 is connected with steel plate 18, when belt transmission 16 is become flexible, make screw rod 19 drive steel plates 18 around hinge through, tightening belt by nut 20.

During work, at first workpiece 21 is put into two fixed heads 13, hold out against in the middle of 14, make an end of extrusion die 11 contact workpieces 21, then, Push switch 22, leading screw 4 rotates and drives top board 2 and slides along slideway 5, then extrusion die 11 is under the drive of push rod 3, slowly in workpiece 21, advance stably, at this moment, top board 2 is at first run into a nearest gripper shoe 6 in the process of advancing, and draws close other two gripper shoes 6 more successively, then the chain 7 of 6 of gripper shoes overlaps, top board 2 moves on until running into contact 10 until first gripper shoe 6 with three gripper shoes 6 are overlapping fully, and top board 2 touches A limit switch 8 rear motors 15 and quits work simultaneously, at this moment, push rod 3 has arrived the end of workpiece, completion of processing.When leading screw 4 counter-rotatings, driving top board 2 shrinks back, push rod 3 also retreats thereupon, pulling by chain 7, three gripper shoe 6 playback, top board 2 touches the B limit switch 23 of the other end again and stops, and push rod 3 is return original position, at last, the workpiece 21 that processes is taken out in the vertical elongated slot on the fixed head 14 from forming tank 9.

Its advantage is: the efficient height, and a people replaces three people work, labor savings, strength is big, steadily, The two rows line is stressed evenly can not be scattered during blanking automatically, safe and reliable, the product quality height, just In making and operation, cost is low.
