[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0003] For example, a Chinese patent application numbered 202320083433.2 discloses a mold tooling for metal workpiece processing, which proposes "comprising a first mold, a stamping groove is provided in the middle of the top end of the first mold, guide rods are provided at the four corners of the top end of the first mold, and the outer walls of the four guide rods are slidably sleeved with a slide plate, a second mold is provided at the bottom end of the slide plate, a pushing assembly is provided in the inner cavity of the second mold, a lifting assembly is provided in the inner cavity of the first mold, a push plate is provided at the top of the lifting assembly, and the push plate is slidably inserted in the stamping groove". However, the above-mentioned mold tooling has a fixed structure, and it is difficult to install different molds during use, resulting in a relatively single production of the mold equipment, and it is inconvenient to position the mold when disassembling and installing the mold, resulting in deviations in the mold installation accuracy. Therefore, the utility model proposes a mold tooling for metal workpiece processing to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a mold tooling for metal workpiece processing, including a base 1, a support frame 2 and a top seat 3. The back side of the top of the base 1 is provided with a support frame 2, the top of the support frame 2 is symmetrically connected with a shock absorber 13, the top of the shock absorber 13 is connected with the top seat 3, the bottom of the top seat 3 is connected with a punch head 4, the top of the base 1 is provided with a fixed block 5, the fixed block 5 is detachably mounted with a mold 6 through a clamping mechanism, the mold 6 is fixed inside the fixed block 5 through the clamping mechanism, and then the stamping part is placed on the top of the mold 6, and pressure is applied to the top seat 3 through external hydraulic equipment. The top seat 3 drives the punch head 4 to move downward, and the stamping part on the top of the mold 6 is automatically punched.

[0020] The punch head 4 is parallel to the mold 6 in upper and lower directions. A groove for accommodating the mold 6 is provided inside the fixed block 5. A positioning mechanism is provided on one side of the groove. The positioning mechanism includes an eccentric wheel 11 and a handle 12. The front side of the base 1 is hinged with an eccentric wheel 11. The outer side of the eccentric wheel 11 is connected with a handle 12. One side of the eccentric wheel 11 is tightly connected to one side of the mold 6. When the mold 6 is inserted into the fixed block 5, the eccentric wheel 11 is driven to rotate by the handle 12, so that the eccentric wheel 11 is tightly connected to one side of the mold 6. The mold 6 is positioned by the eccentric wheel 11 and the fixed block 5, so that the mold 6 is fixed more stably inside the fixed block 5.

[0021] The clamping mechanism includes a clamping plate 8, a slide groove 9 and a threaded rod 10. The clamping plates 8 are symmetrically slidably installed on both sides of the fixed block 5. The slide groove 9 is arranged inside the clamping plate 8. A group of threaded rods 10 are symmetrically arranged on both sides of the fixed block 5. The top of the threaded rod 10 is threadedly connected with a nut. The top of the nut is provided with a hexagonal hole. The bottom diameter of the nut is larger than the width of the slide groove 9. The top of the mold 6 is fitted and connected with the bottom of the clamping plate 8. The mold 6 is placed inside the fixed block 5, and then the hexagonal wrench is inserted into the threaded rod 10. The top nut is inserted into the hexagonal hole of the threaded rod 10 and loosened, and the clamping plate 8 is pushed to move toward the mold 6 to cover the clamping plate 8 on the top of the mold 6. Then the nut at the top of the threaded rod 10 is tightened, and the clamping plate 8 and the mold 6 are clamped by the threaded rod 10, so that the mold 6 is fixed inside the fixed block 5. When the mold 6 needs to be taken out and replaced, the nut at the top of the threaded rod 10 is loosened again, the clamping plate 8 is pushed to reset, and then the new mold 6 is inserted into the inside of the fixed block 5. Repeat the above steps and fix the new mold 6 into the fixed block 5 to complete the replacement.

[0022] The shock absorber 13 is composed of a telescopic rod 14, a top cover 15, a damping pad 16 and a spring 17. The spring 17 is sleeved on the outer side of the telescopic rod 14. The top end of the telescopic rod 14 is connected to the top seat 3 through the top cover 15. The damping pad 16 is arranged inside the telescopic rod 14. When the top seat 3 drives the punch head 4 to move downward, the telescopic rod 14 is driven to retract inward. During the process, the telescopic rod 14 and the damping pad 16 generate friction to consume the downward kinetic energy of the top seat 3. The elastic force generated by the spring 17 is used to drive the top seat 3 to automatically move upward when the external hydraulic equipment no longer applies pressure, so as to reduce the shock of the top seat 3.

[0023] A movable bin 18 is provided inside the base 1, and the mold 6 is parallel to the movable bin 18 in the upper and lower parts. A rotating pin 19 is hinged on one side of the movable bin 18, and a bolt 20 is connected to the back side of the base 1. An arc groove 21 is provided at one end of the rotating pin 19, and one end of the bolt 20 passes through the interior of the arc groove 21 and is threadedly connected with a nut. The stamped waste automatically falls into the movable bin 18, and then the nut on the outside of the bolt 20 is loosened, and the rotating pin 19 is rotated to separate the bolt 20. At this time, the movable bin 18 can be pulled out from the inside of the base 1, so that the waste in the movable bin 18 can be cleaned conveniently, and then the movable bin 18 is stuffed back into the inside of the base 1, and the rotating pin 19 is rotated to reset and combine the arc groove 21 and the bolt 20 together. Finally, the nut on the outside of the bolt 20 is tightened to lock the position of the movable bin 18.

[0024] The mold tooling for metal workpiece processing places the mold 6 into the interior of the fixed block 5, then inserts the hexagonal wrench into the hexagonal hole of the nut at the top of the threaded rod 10 and loosens it, pushes the clamping plate 8 to move in the direction of the mold 6, so as to cover the clamping plate 8 on the top of the mold 6, then tightens the nut at the top of the threaded rod 10, and uses the threaded rod 10 to clamp the clamping plate 8 and the mold 6, so that the mold 6 is fixed inside the fixed block 5. When the mold 6 needs to be taken out and replaced, the nut at the top of the threaded rod 10 is loosened again, the clamping plate 8 is pushed to reset, and then the new mold 6 is inserted into the interior of the fixed block 5, and the above steps are repeated to fix the new mold 6 into the fixed block 5 to complete the replacement.

[0025] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
