Description

Technical Field

[0001] This utility model relates to the field of hardware mold production technology, specifically a stamping device for hardware mold production. Background Technology

[0002] In the field of hardware mold manufacturing, stamping is a key process for manufacturing core components such as mold bases and templates. It requires the use of punches and slots in a stamping device to punch and form metal blanks (such as steel plates and aluminum alloy plates), laying the foundation for subsequent assembly of guide pillars, punches, dies and other accessories.

[0003] Based on the above, the inventors have discovered the following problems: When stamping the blank of the mold base of the hardware mold, metal scrap is continuously generated in the stamping groove, such as the circular metal sheet formed during the punching process. Due to the lack of real-time scrap cleaning function of the stamping device, the metal scrap will continue to accumulate inside the stamping groove. When the scrap in the stamping groove accumulates to a certain extent, the stamping operation must be stopped and the operator must clean it manually. During the cleaning process, tools such as tweezers and hooks need to be used to reach into the stamping groove to remove the scrap one by one, which is cumbersome.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a stamping device for the production of hardware molds, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a stamping device for the production of hardware molds, so as to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A stamping device for producing metal molds includes a stamping assembly and a waste material adsorption assembly. The stamping assembly includes a pair of base frames, with a stamping female seat installed between the base frames. The stamping female seat has grooves at its four corners. The waste material adsorption assembly includes a connecting seat with four through holes on its top surface. A negative pressure pipe is installed inside each of the four through holes, and an adsorption head is installed at the top of each of the four negative pressure pipes. The four adsorption heads are aligned with the four grooves, and the ends of the four adsorption heads away from the negative pressure pipes are at a distance from the bottom surface of the stamping female seat. A negative pressure pump is installed on one side of the outer wall of the connecting seat, and the air inlet of the negative pressure pump extends through the connecting seat into its interior.

[0008] The beneficial effects of adopting the above-mentioned further solution are as follows: after the negative pressure pump is started, the connecting seat is in a negative pressure state, and the suction force is transmitted to the adsorption head through the connecting seat and the negative pressure pipe. The adsorption head is aligned with the stamping groove, and can directly adsorb the waste generated in the stamping groove during the stamping process, preventing the waste from accumulating in the stamping groove. At the same time, during the stamping process when no waste is being sucked up, the adsorption head maintains a distance from the bottom surface of the stamping nut, which does not affect the normal operation of the stamping nut. After the stamping is completed, the thin tube section of the adsorption head enters the stamping groove and contacts the bottom surface of the waste. Then the thin tube section returns to its original position, so that the waste is removed from the stamping groove in time under the action of adsorption force and tension, realizing the precise adsorption and timely cleaning of stamping waste, and avoiding the impact of waste residue on the stamping quality.

[0009] Furthermore, the adsorption head is composed of a coarse tube section and a fine tube section. One end of the negative pressure tube is connected to the coarse tube section. The inner diameter of the coarse tube section is larger than the inner diameter of the fine tube section. A round hole is provided at the end of the fine tube section away from the coarse tube section.

[0010] The beneficial effects of adopting the above-mentioned further solution are that the larger inner diameter of the thicker pipe section can reduce the transmission resistance of negative pressure in the pipe, so that the suction force generated by the negative pressure pump can be transmitted to the thinner pipe section more efficiently; the smaller inner diameter of the thinner pipe section can form concentrated suction force at the round hole, and the concentrated suction force can improve the adsorption capacity, ensure the effective adsorption of waste in the flushing groove, and avoid waste residue in the flushing groove.

[0011] Furthermore, there is a gap between the pair of base frames, and grooves are provided on both sides of the outer wall of the stamping base. Electric telescopic rods are installed inside the two grooves. The telescopic ends of the two electric telescopic rods are fixedly connected to the top sides of the connecting seat. The telescopic amount, telescopic speed and telescopic direction of the telescopic ends of the two electric telescopic rods are consistent.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the electric telescopic rod can drive the connecting seat to move the negative pressure pipe and the adsorption head in the vertical direction, adjusting the distance between the adsorption head and the bottom surface of the stamping mother seat; after the stamping is completed and the waste is stuck in the punch groove, the height of the waste adsorption component is adjusted so that the adsorption head part enters the punch groove, reducing the distance between the end face of the thin tube section and the bottom surface of the waste. Then, the negative pressure pump and the electric telescopic rod are started. Under the action of the negative pressure pump, the adsorption force generated at the round hole of the adsorption head, together with the electric telescopic rod, pushes the waste adsorption component down, slowly sucking the waste out of the punch groove. Then, the negative pressure pump stops working and no longer draws air out of the connecting seat. The adsorption force at the round hole of the adsorption head disappears, and the waste that has been discharged from the punch groove (not stuck in the punch groove) falls onto the connecting seat under the action of gravity.

[0013] Furthermore, a stamping male seat is provided at the upper end of the stamping female seat, and punches are installed at the four corners of the bottom surface of the stamping male seat. The four punches are aligned with the four stamping slots, and the outer walls of the four punches are respectively matched with the inner walls of the four stamping slots.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the punch and the slot correspond one-to-one and fit precisely. During stamping, the punch can be accurately embedded in the slot to punch the die blank, such as the die base, placed on the stamping base, which facilitates the subsequent assembly of guide pillars and other accessories with the punch or die.

[0015] Furthermore, a cylinder is provided on the top surface of the stamping male seat, the telescopic end of the cylinder passes through the top seat, and the telescopic end of the cylinder is fixedly connected to the top surface of the stamping male seat.

[0016] The beneficial effects of adopting the above-mentioned further solution are that the cylinder, as a power source, can drive the stamping male seat to rise and fall stably in the vertical direction. When the mold is closed, the cylinder extends to push the stamping male seat down, and the punch and the slot cooperate to complete the stamping. When the mold is opened, the cylinder retracts to drive the male seat up, making it easier to remove the stamped part. The stamping pressure and lifting speed of the cylinder can be adjusted according to the material and thickness of the mold blank, avoiding excessive pressure that could damage the mold or deform the stamped part, and also preventing insufficient pressure that could lead to incomplete stamping.

[0017] Furthermore, the male stamping seat has sliding holes inside near the four corners, and guide rods are slidably connected inside each of the four sliding holes. The outer wall of one end of each of the four guide rods is fixedly connected to the top surface of the female stamping seat, and the outer wall of the end of each of the four guide rods away from the female stamping seat is fixedly connected to the bottom surface of the male stamping seat.

[0018] The beneficial effects of adopting the above-mentioned further solution are that the sliding fit between the guide rod and the sliding hole ensures that the stamping male seat only moves up and down in the vertical direction, avoiding the stamping male seat from shifting during the stamping process, which would cause the punch and the slot to misalign, resulting in scrap of the stamped part or damage to the mold; at the same time, the guide rod can disperse the lateral force during stamping, reduce the stress on the cylinder extension end, and extend the service life of the cylinder.

[0019] Furthermore, a pair of connecting holes are provided on the top surface of each of the opposite ends of the base frame, and the inner walls of both pairs of connecting holes are provided with internal threads.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the internal thread of the connecting hole can be used to install the base frame in a designated position, such as on the mounting base workbench. A square groove is opened on the workbench, and the waste adsorption component is located below the workbench through the square groove, that is, the waste adsorption component is suspended.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: In this stamping device for hardware mold production, the electric telescopic rod can drive the connecting seat to move the negative pressure pipe and the suction head vertically, adjusting the distance between the suction head and the bottom surface of the stamping base. After stamping, when the waste material is stuck in the punch groove, the height of the waste material suction assembly is adjusted so that part of the suction head enters the punch groove, reducing the distance between the end face of the thin tube section and the bottom surface of the waste material. Then, the negative pressure pump and the electric telescopic rod are started. After the negative pressure pump starts, the connecting seat is in a negative pressure state, and the suction force is transmitted through the connecting... The negative pressure pipe is transmitted to the adsorption head, which is aligned with the punching groove. It can directly adsorb the waste generated in the punching groove during the stamping process, preventing the waste from accumulating in the punching groove. Under the action of the negative pressure pump, the adsorption force generated at the round hole of the adsorption head, together with the electric telescopic rod, pushes the waste adsorption component down, slowly sucking the waste out of the punching groove. Then the negative pressure pump stops working and no longer draws air out of the connecting seat. The adsorption force at the round hole of the adsorption head disappears. The waste that has been discharged from the punching groove (not stuck in the punching groove) falls onto the connecting seat under the action of gravity. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 This utility model provides a technical solution: a stamping device for hardware mold production, including a stamping assembly 1 and a waste adsorption assembly 2. The stamping assembly 1 includes a pair of base frames 12, and a stamping female seat 13 is installed between the pair of base frames 12. The stamping female seat 13 has a groove 14 inside at each of its four corners. The waste adsorption assembly 2 includes a connecting seat 21, and four through holes are provided on the top surface of the connecting seat 21. A negative pressure pipe 22 is installed inside each of the four through holes. An adsorption head 23 is installed at the top of each of the four negative pressure pipes 22. The four adsorption heads 23 are respectively aligned with the four grooves 14, and the four adsorption heads 23 are away from the negative pressure pipes. One end of the tube 22 is at a distance from the bottom surface of the stamping base 13. A negative pressure pump 24 is installed on one side of the outer wall of the connecting seat 21. The air inlet of the negative pressure pump 24 extends through the connecting seat 21 and into its interior. The suction head 23 consists of a coarse tube section 2301 and a fine tube section 2302. One end of the negative pressure tube 22 is connected to the coarse tube section 2301. The inner diameter of the coarse tube section 2301 is larger than the inner diameter of the fine tube section 2302. A round hole is provided at the end of the fine tube section 2302 away from the coarse tube section 2301. There is a gap between the pair of base frames 12. Grooves are provided on both sides of the outer wall of the stamping base 13. Both grooves are equipped with [missing information]. The electric telescopic rods 3, with their telescopic ends fixedly connected to both sides of the top surface of the connecting seat 21, drive the connecting seat 21 to move the negative pressure pipe 22 and the suction head 23 vertically, adjusting the distance between the suction head 23 and the bottom surface of the stamping base 13. After stamping, when the waste material is stuck in the punching groove 14, the height of the waste material adsorption assembly 2 is adjusted so that part of the suction head 23 enters the punching groove 14, reducing the distance between the end face of the thin tube section 2302 and the bottom surface of the waste material. Then, the negative pressure pump 24 and the electric telescopic rods 3 are started. After the negative pressure pump 24 is started, the connecting seat 21 is in a negative pressure state, and the suction force is transmitted through the connecting... The pressure is transmitted from the connecting seat 21 and the negative pressure pipe 22 to the adsorption head 23. The adsorption head 23 is aligned with the punching groove 14 and can directly adsorb the waste generated in the punching groove 14 during the stamping process to prevent the waste from accumulating in the punching groove 14. Under the action of the negative pressure pump 24, the round hole of the adsorption head 23 generates an adsorption force, which, together with the electric telescopic rod 3, pushes the waste adsorption component 2 down to slowly suck the waste out of the punching groove 14. Then the negative pressure pump 24 stops working and no longer draws air out of the connecting seat 21. The adsorption force at the round hole of the adsorption head 23 disappears. The waste that has been discharged from the punching groove 14 and is not stuck in the punching groove 14 falls onto the connecting seat 21 under the action of gravity.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5 This utility model provides a technical solution: a stamping male seat 15 is provided at the upper end of a stamping female seat 13. Punches 16 are installed at the four corners of the bottom surface of the stamping male seat 15, with each of the four punches 16 aligned with one of the four punch slots 14. The outer walls of the four punches 16 respectively cooperate with the inner walls of the four punch slots 14. A cylinder 18 is provided on the top surface of the stamping male seat 15, with the telescopic end of the cylinder 18 penetrating through the top seat 11 and fixedly connected to the top surface of the stamping male seat 15. Sliding holes are provided inside the stamping male seat 15 near the four corners, and guide rods 17 are slidably connected inside each of the four sliding holes. The outer wall of one end of each of the four guide rods 17 is connected to the top surface of the stamping female seat 13. The four guide rods 17 are fixedly connected to the bottom surface of the stamping male seat 15 on the outer wall of the end away from the stamping female seat 13. A pair of connecting holes 19 are opened on the top surface of the opposite ends of the pair of base frames 12. The inner walls of the two pairs of connecting holes 19 are provided with internal threads. When the mold is closed, the cylinder 18 extends to push the stamping male seat 15 down, and the punch 16 cooperates with the punch groove 14 to complete the stamping. When the mold is opened, the cylinder 18 retracts to drive the male seat up, making it easier to remove the stamped part. The sliding cooperation between the guide rods 17 and the sliding holes ensures that the stamping male seat 15 only moves up and down in the vertical direction, avoiding the stamping male seat 15 from shifting during the stamping process, which would cause the punch 16 and the punch groove 14 to misalign, resulting in the scrapping of the stamped part or damage to the mold.

[0032] Specifically, the working principle of this stamping device for hardware mold production is as follows: During use, the internal thread of the connecting hole 19 can be used with bolts to install the base frame 12 in a designated position, such as on the mounting table. A square slot is opened on the table, and the waste material adsorption component 2 is located below the table surface through the square slot, i.e., the waste material adsorption component 2 is suspended. When the mold is closed, the cylinder 18 extends to push the stamping male seat 15 down, and the punch 16 cooperates with the punch groove 14 to complete the stamping. When the mold is opened, the cylinder 18 retracts to drive the male seat up, making it easy to remove the stamped part. The sliding cooperation between the guide rod 17 and the sliding hole ensures that the stamping male seat 15 only moves up and down in the vertical direction, avoiding the stamping male seat 15 from shifting during the stamping process, which would cause the punch 16 and the punch groove 14 to misalign, resulting in scrapped stamped parts or mold damage. The electric telescopic rod 3 can drive the connecting seat 21 to move the negative pressure pipe 22 and the adsorption head 23 in the vertical direction, adjusting the distance between the adsorption head 23 and the bottom surface of the stamping female seat 13. When the stamping is completed, the waste material is stuck in the hole. After entering the punching groove 14, adjust the height of the waste adsorption component 2 so that the adsorption head 23 partially enters the punching groove 14, reducing the distance between the end face of the thin tube section 2302 and the bottom surface of the waste. Then, start the negative pressure pump 24 and the electric telescopic rod 3. After the negative pressure pump 24 starts, the connecting seat 21 is in a negative pressure state. The suction force is transmitted to the adsorption head 23 through the connecting seat 21 and the negative pressure pipe 22. The adsorption head 23 is aligned with the punching groove 14 and can directly adsorb the waste generated in the punching groove 14 during the punching process, preventing the waste from accumulating in the punching groove 14. The adsorption force generated at the round hole of the adsorption head 23 under the action of the negative pressure pump 24, together with the electric telescopic rod 3, pushes the waste adsorption component 2 down, slowly sucking the waste out of the punching groove 14. Then, the negative pressure pump 24 stops working and no longer pumps air out of the connecting seat 21. The adsorption force at the round hole of the adsorption head 23 disappears. The waste that has been discharged from the punching groove 14 and is not stuck in the punching groove 14 falls onto the connecting seat 21 under the action of gravity.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
