The fixed bolt 207 of being convenient for passes the jack and fixes terrace die 204, and the thrust slot has been seted up to backing plate 201 one side, and thrust slot one end runs through second spout 205, and the thrust slot height is the same with connecting rod 208 diameter size, is convenient for promote to control connecting rod 208 and slide in the thrust slot 209 to the fixed bolt 207 of control compression first compression spring 206 slides in inside the second spout 205, thereby can dismantle terrace die 204.

all welding of 1 bottom four corners position department of cope match-plate pattern has guide bar 3, and 3 outside bottoms of guide bar have cup jointed uide bushing 4, and four uide bushing 4 bottoms weld respectively in 5 top four corners position departments of lower bolster, and the cope match-plate pattern 1 of being convenient for is accurate to dock with lower bolster 5.

the top end of the lower template 5 is provided with a bottom template assembly 6, and the bottom template assembly 6 comprises a fixed sleeve plate 601, a female die 602, a first groove 603, a limiting plate 604, a second compression spring 605, a second groove 606, a third compression spring 607 and a movable plate 608;

the welding of lower bolster 5 top has fixed lagging 601, die 602 is installed on fixed lagging 601 top, first recess 603 has been seted up on fixed lagging 601 top, limiting plate 604 is installed through the screw in die 602 bottom, the even welding of limiting plate 604 bottom has second compression spring 605, second recess 606 has all been seted up to die 602 top both sides, the even welding of second recess 606 bottom has third compression spring 607, third compression spring 607 top welds in fly leaf 608 bottom, the welding of second compression spring 605 bottom is in first recess 603 inner wall bottom, be convenient for carry out stamping work during die 602 bottom compression second compression spring 605, sheet metal baffle 7 has all been welded to die 602 both sides, restrict the sheet metal material position.

The working principle and the using process of the invention are as follows: firstly, the handle 209 is pushed to the end far away from the first chute 202 by hand control, so that the fixed pin 207 compresses the first compression spring 206, and the fixed pin 207 slides into the second chute 205 completely, then the slide block 203 welded at the top end of the male die 204 is aligned with the open end of the first chute 202, the slide block 203 slides to the tail end of the first chute 202, and then the handle 209 is released, and the fixed pin 207 is inserted into the jack arranged on the slide block 203 due to the action of the rebounding force of the first compression spring 206, so that the slide block 203 with the male die 204 is fixed at the bottom end of the backing plate 201 and does not slide, thereby facilitating the installation and the disassembly of the male die 204, and facilitating the replacement and the maintenance of the male die 204;

secondly, a sheet metal material is placed on movable plates 608 on two sides of the top end of a female die 602, two ends of the sheet metal material are limited by limiting plates 604, a punching head of an external punching device is connected with the top end of an upper template 1, a lower template 5 is placed on a plane, the bottom ends of guide rods 3 at four corners of the bottom end of the upper template 1 are aligned with the top ends of guide sleeves 4 at four corners of the top end of the lower template 5, so that the upper template 1 and the lower template 5 can be in complete butt joint, the punching device enables the upper template 1 to move downwards, when a male die 204 contacts the sheet metal material, downward pressure is applied to the sheet metal material, two ends of the sheet metal material enable the movable plates 608 to compress third compression springs 607 to move downwards until the top ends of the movable plates 608 are flush with the top end of the female die 602, meanwhile, the female die 602 compresses the second compression springs 605 to slide in the fixed sleeve 601 until the limiting plates 604 reach, the sheet metal material is prevented from being broken when suddenly subjected to large pressure;

Finally, after the stamping operation is completed, the upper die plate 1 is lifted to be separated, and at this time, the movable plate 608 is moved upwards due to the action of the rebounding force of the third compression spring 607, so that the sheet metal material is driven to move upwards to be separated from the concave arc of the female die 602, and the sheet metal material is convenient to take out.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
