Description

Technical Field

[0001] The present invention relates to the technical field of stamping dies, and particularly to an anti-jumping waste sheet metal stamping die. Background Art

[0002] Stamping is a forming process that applies external forces to sheets, strips, tubes, profiles, etc. by a press and a die, causing plastic deformation or separation to obtain workpieces with the required shape and size. Stamping and forging belong to plastic processing and are collectively called forging and pressing. The blanks for stamping are mainly hot-rolled and cold-rolled steel sheets and strips. Among the world's steel, 60-70% is sheet metal, and most of it is made into finished products through stamping. Automobile bodies, chassis, fuel tanks, radiator fins, steam drums of boilers, shells of containers, silicon steel sheets for cores of motors and electrical appliances, etc. are all processed by stamping.

[0003] Most of the stamping equipment in small production companies now uses the method of manually supporting the raw materials for stamping. In this stamping method, when the die is not tight enough, it is easy to have the situation of material jumping during stamping, which affects the stamping efficiency and increases the stamping cost. At the same time, completely fixing the original sheet may cause deformation due to the problem of stamping force, and it will also cause a large amount of waste of raw materials.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] Refer to Figures 1-4 , an anti-jumping waste sheet metal stamping die, comprising: a top seat 1, a base 5 and a movable sleeve 6;

[0029] On both sides of the top of the base 5, support rods 4 are fixedly installed. The support rods 4 can support and fix the device, improve the stability of the device support, and at the same time avoid the problem of shaking during stamping between the two top seats 1 and the base 5. At the top of the support rod 4, a pressing rod 3 is installed. The pressing rod 3 can further limit the device to avoid the problem of dislocation. At the top of the pressing rod 3, a movable block 2 is movably installed. The movable block 2 moves on the outer pressing rod 3. At the top of the movable block 2, a top seat 1 is fixedly installed. The top seat 1 is used to connect and install the upper die and the stamping machine. Inside the top seat 1 and the base 5, a fixator 12 is fixedly installed. The fixator 12 fixes the internal plate to avoid shaking during use. On one side of the fixator 12, a movable sleeve 6 is installed. The movable sleeve 6 can adjust the length to fix the raw material plate 10 at different positions, increasing the convenience of device installation;

[0030] At one end of the movable sleeve 6, a knob 7 is movably installed. The knob 7 can effectively adjust the internal lead screw 8, so that the position of the bottom pressing plate 9 can be adjusted by rotating the lead screw 8 to fix different raw material plates 10. Inside the knob 7, a lead screw 8 is installed by thread. At the bottom of the lead screw 8, a pressing plate 9 is rotatably installed. The pressing plate 9 fixes the internal raw material plate 10. Between the movable sleeve 6 and the fixator 12, a raw material plate 10 is placed. The raw material plate 10 is the raw material plate for stamping.

[0031] The inner side of the fixator 12 is filled with a buffer solution 16, which is made of oil, so that it can shrink under the extrusion of the rubber pad 13. A sealing ring 14 is movably installed inside the fixator 12. The sealing ring 14 can increase the sealing performance of the device and prevent the oil from leaking. A rubber pad 13 is fixedly installed on the top of the sealing ring 14. The rubber pad 13 can effectively fix the raw material plate 10. A connector 15 is fixedly installed on one side of the fixator 12, and the connector 15 can discharge the internal oil.

[0032] The bottom of the base 5 is installed with a die base 20 through fixing bolts 18. The die base 20 can install the edge stabilizing block 21 of the device. The edge stabilizing block 21 is fixedly installed on the top of the die base 20. The edge stabilizing block 21 increases the overall strength of the device. A die block 19 is arranged inside the edge stabilizing block 21.

[0033] An activity groove 22 is arranged inside the die block 19. The activity groove 22 moves the internal top block 23 to prevent the top block 23 from moving by itself. A top block 23 is movably installed inside the activity groove 22. A connecting rod 24 is fixedly installed at the bottom of the top block 23. The connecting rod 24 improves the convenience of device connection.

[0034] A top spring 26 is installed at the bottom inside the die block 19. The top spring 26 can eject the top block 23 at the top of the device. A sleeve 25 is movably installed on the outer side of the top spring 26. The sleeve 25 fixes the top spring 26 on the outer wall to prevent the spring from becoming scattered during use. The top of the top spring 26 is fixedly connected to the connecting rod 24;

[0035] A first backing plate 11 is arranged on one side of the base 5. The first backing plate 11 facilitates the installation and fixation of the whole die. A bottom plate 17 is arranged between the base 5 and the first backing plate 11.

[0036] Working principle: When in use, first install this device in a stamping machine, and then rotate the knob 7 to drive the screw rod 8 inside the knob 7 to rotate. The rotation of the screw rod 8 will drive the position of the pressing plate 9 to be adjusted. Then insert the raw material plate 10 into the appropriate position. When stamping, the top seat 1 will press down. When the top seat 1 presses down, it will be restricted by the movable block 2 and the support rod 4. Then after stamping, the top block 23 inside the die block 19 will eject the stamping formed part.
