Description

Technical Field

[0001] This utility model relates to the field of stamping and punching technology, specifically a dual-station composite mold for stamping and punching. Background Technology

[0002] With technological advancements and improved living standards, automobiles have become a common part of everyday life. To enhance driving safety and protect drivers and passengers, airbags are generally installed in vehicles to protect them in the event of a dangerous situation. An airbag assembly mainly consists of the airbag, a gas generator, and an igniter. The gas generator typically includes a diffuser. The diffuser guides the gas generated in the gas generator into the airbag to inflate it. The diffuser is generally formed by stamping, and after stamping, it requires side punching.

[0003] Based on the above, the inventors have discovered the following problems: In the current diffuser shell processing, the material plate must first be placed on the lower die of a stamping mold and stamped into a cylindrical shape. Then, the stamped shell is transferred to a punching machine for punching. This process is cumbersome and reduces the production efficiency of diffuser shells. Therefore, in view of this, the inventors have researched and improved the existing structure and its shortcomings, providing a dual-station composite stamping and punching mold to achieve a more practical purpose. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-station composite die for stamping and punching to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A dual-station composite stamping and punching mold includes a stamping assembly and a punching assembly. The punching assembly includes a mounting base, with circular columns mounted at both ends of the mounting base. Each of the two circular columns has a pair of grooves inside, and circular holes are formed on the outer walls of the two circular columns at the locations of the grooves. A stamping rod is slidably mounted within each pair of circular holes. The stamping assembly includes a base, with a pair of lower stamping seats mounted on the top surface of the base. Smooth rods are mounted at the four corners of the upper end of the base, and connecting plates are slidably connected to the outside of the smooth rods. A connecting seat is mounted on the bottom end of the connecting plate, and upper stamping seats are mounted on both sides of the bottom end of the connecting seat. A second hydraulic cylinder is embedded inside the base, with its movable end penetrating the base and fixedly connected to the bottom surface of the mounting base. A pair of stamping through holes are formed on the top surfaces of each pair of lower stamping seats.

[0007] Furthermore, a square plate is slidably connected inside each of the pair of square grooves, the outer wall of the square plate is clearance-fitted with the inner wall of the square groove, and one side of the square plate is fixedly connected to one end of the stamping rod.

[0008] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the square groove and the square plate, when the square plate is pushed, due to the clearance fit between the outer wall of the square plate and the inner wall of the square groove, it moves back and forth stably in the square groove, thereby realizing the back and forth movement of the stamping rod.

[0009] Furthermore, hydraulic rods are installed on the inner walls of each pair of square grooves, and the movable end of the hydraulic rod is fixedly connected to the end of the square plate away from the stamping rod.

[0010] The advantage of adopting the above-mentioned further solution is that by installing a hydraulic rod, it is easier to push the square plate when the hydraulic rod is activated.

[0011] Furthermore, the outer wall of the stamping rod is clearance-fitted with the inner wall of the stamping through hole, and the central axes of the stamping rod and the stamping through hole are collinear.

[0012] The beneficial effect of adopting the above-mentioned further solution is that when the stamping rod extends out of the round hole under the pushing action, and with the cooperation of the stamping through hole, the side opening operation is realized on the shell that has been stamped into a cylindrical shape.

[0013] Furthermore, the lower stamping seat has an internal slot, the upper end of the lower stamping seat has a first semi-circular groove, the bottom end of the upper stamping seat has a second semi-circular groove, the top surface of the lower stamping seat is inclined on both sides, and the top surface of the lower stamping seat is clearance-fitted with the bottom surface of the upper stamping seat.

[0014] Furthermore, a circular groove is formed between the inner wall of the first semicircular groove and the inner wall of the second semicircular groove.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the first semi-circular groove and the second semi-circular groove, there is a certain distance between the lower stamping seat and the mounting seat, and a certain distance between the mounting seat and the upper stamping seat. The material plate to be stamped is placed on the two circular pillars. Then, when the upper stamping seat moves downward, the material plate is first stamped into a U-shape. Then, the upper stamping seat and the mounting seat move downward together. During the continuous downward movement, the material plate is stamped again until the upper stamping seat and the lower stamping seat close. A circular groove is formed between the first semi-circular groove and the second semi-circular groove, so that the material plate forms a closed cylindrical shape under the stamping action. Since the lower stamping seat has a hollow groove inside, the waste material formed after punching accumulates in the hollow groove of the lower stamping seat, so that the subsequent operators can clean up the waste material.

[0016] Furthermore, a top seat is installed between the upper ends of the four light rods, and a first hydraulic cylinder is installed at the center of the upper end of the top seat. The movable end of the first hydraulic cylinder extends through the top seat to the outside, and the movable end of the first hydraulic cylinder is fixedly connected to the upper end of the connecting plate.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by setting the first hydraulic cylinder, when the first hydraulic cylinder is started, it is easy to drive the connecting plate to move downward stably under the sliding limit action of the light rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This dual-station composite stamping and punching mold, by activating the second hydraulic cylinder, prevents the bottom end of the mounting seat from contacting the upper end of the base, i.e., there is a certain distance between the lower stamping seat and the mounting seat, and a certain distance between the mounting seat and the upper stamping seat. The material plate to be stamped is placed on the two circular pillars. Then, the first hydraulic cylinder is activated, facilitating the stable downward movement of the connecting plate under the sliding limit action of the guide rod. This causes the upper stamping seat to move downward, allowing the first semi-circular groove to engage with the circular pillar, first stamping the material plate into a U-shape. Then, through the first and second hydraulic cylinders, the upper stamping seat and the mounting seat move downward together. During this continuous downward movement, the material plate is stamped into a U-shape. The material plate is then stamped until the upper and lower stamping seats are closed, forming a circular groove between the first and second semicircular grooves. This causes the material plate to form a closed cylindrical shape under the stamping action. When the hydraulic rod is activated, it facilitates the pushing of the square plate. Due to the clearance fit between the outer wall of the square plate and the inner wall of the square groove, it moves stably within the square groove, thereby enabling the stamping rod to move outward from the cylindrical shape. When the stamping rod extends out of the circular hole under the pushing action, it performs side opening operations on the cylindrical shell that has already been stamped under the action of the stamping through hole. Since the lower stamping seat has an empty groove inside, the waste material formed after punching accumulates in the empty groove of the lower stamping seat, making it easier for subsequent operators to clean up the waste material.

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1-5This utility model provides a technical solution: a dual-station composite die for stamping and punching, including a stamping assembly 100 and a punching assembly 500. The punching assembly 500 includes a mounting base 5001, with circular pillars 5002 mounted at both ends of the mounting base 5001. A pair of countersunk grooves 5003 are formed inside each of the two circular pillars 5002. Circular holes 5004 are formed on the outer walls of the two circular pillars 5002 at the countersunk grooves 5003. A stamping rod 5006 is slidably mounted within each pair of circular holes 5004. The stamping assembly 100 includes a base 1001, with a pair of lower stamping seats 1002 mounted on the top surface of the base 1001. Smooth rods 1004 are mounted at the four corners of the upper end of the base 1001. The outer surfaces of the smooth rods 1004 slide... A connecting plate 1007 is connected to the base 1007. A connecting seat 1008 is installed at the bottom of the connecting plate 1007. Upper stamping seats 1009 are installed on both sides of the bottom of the connecting seat 1008. A second hydraulic cylinder 1010 is embedded in the base 1001. The movable end of the second hydraulic cylinder 1010 passes through the base 1001 and is fixedly connected to the bottom surface of the mounting seat 5001. A pair of lower stamping seats 1002 have a pair of stamping through holes 1003 on their top surfaces. By activating the second hydraulic cylinder 1010, the bottom of the mounting seat 5001 is no longer in contact with the top of the base 1001. At this time, there is a certain distance between the lower stamping seats 1002 and the mounting seat 5001, and there is a certain distance between the mounting seat 5001 and the upper stamping seats 1009.

[0027] 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.

[0028] Please see Figures 1-5This utility model provides a technical solution: Square plates 5005 are slidably connected to the interior of a pair of square grooves 5003. The outer wall of the square plate 5005 is clearance-fitted with the inner wall of the square groove 5003. One side of the square plate 5005 is fixedly connected to one end of a stamping rod 5006. Hydraulic rods 5007 are installed on the inner sidewalls of a pair of square grooves 5003. The movable end of the hydraulic rod 5007 is fixedly connected to the end of the square plate 5005 away from the stamping rod 5006. The outer wall of the stamping rod 5006 is clearance-fitted with the inner wall of the stamping through hole 1003. The central axes of the adjacent stamping rod 5006 and the stamping through hole 1003 are collinear. The hydraulic rod 5007 is activated, which facilitates the pushing of the square plate 5005. Since the outer wall of the square plate 5005 is clearance-fitted with the inner wall of the square groove 5003, it moves stably within the square groove 5003, thereby enabling the stamping rod 5006 to move outward from the cylindrical column 5002. When the stamping rod 5006 extends out of the circular hole 5004 under the pushing action, and with the cooperation of the stamping through hole 1003, it performs the side opening operation on the cylindrical shell that has been stamped.

[0029] 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.

[0030] Please see Figures 1-5This utility model provides a technical solution: a slot 400 is provided inside the lower stamping seat 1002, a first semi-circular groove 200 is provided at the upper end of the lower stamping seat 1002, and a second semi-circular groove 300 is provided at the bottom end of the upper stamping seat 1009. The top surface of the lower stamping seat 1002 is inclined on both sides, and the top surface of the lower stamping seat 1002 is clearance-fitted with the bottom surface of the upper stamping seat 1009. A circular groove is formed between the inner walls of the first semi-circular groove 200 and the inner walls of the second semi-circular groove 300. A top seat 1005 is installed between the upper ends of the four light rods 1004. A first hydraulic cylinder 1006 is installed at the center of the upper end of the top seat 1005. The movable end of the first hydraulic cylinder 1006 extends through the top seat 1005 to the outside, and the movable end of the first hydraulic cylinder 1006 is fixedly connected to the upper end of the connecting plate 1007. Because the lower stamping seat 1002 has a slot 400 inside... A slot 400 is provided, allowing the waste material formed after punching to accumulate in the slot 400 of the lower stamping seat 1002, facilitating subsequent cleaning by operators. The first hydraulic cylinder 1006 is activated, which drives the connecting plate 1007 to move stably downward under the sliding limit action of the guide rod 1004, causing the upper stamping seat 1009 to move downward. This causes the first semi-circular groove 200 to engage with the circular column 5002, firstly stamping the material plate into a U-shape. Then, through the first hydraulic cylinder 1006 and the second hydraulic cylinder 1010, the upper stamping seat 1009 and the mounting seat 5001 move downward together. During the continuous downward movement, the material plate is stamped until the upper stamping seat 1009 and the lower stamping seat 1002 close, forming a circular groove between the first semi-circular groove 200 and the second semi-circular groove 300, thus forming a closed cylindrical shape of the material plate under the stamping action.

[0031] Specifically, the working principle of this dual-station composite stamping and punching mold is as follows: During use, the second hydraulic cylinder 1010 is activated, causing the bottom end of the mounting base 5001 to no longer adhere to the upper end of the base 1001. This creates a certain distance between the lower stamping seat 1002 and the mounting base 5001, and between the mounting base 5001 and the upper stamping seat 1009. The material to be stamped is placed on the two circular pillars 5002. Then, the first hydraulic cylinder 1006 is activated, facilitating the stable downward movement of the connecting plate 1007 under the sliding limit action of the guide rod 1004. This causes the upper stamping seat 1009 to move downward, engaging the first semi-circular groove 200 with the circular pillar 5002, first stamping the material into a U-shape. Then, through the first hydraulic cylinder 1006 and the second hydraulic cylinder 1010, the upper stamping seat 1009 and the mounting base 5001 move downward together. During this continuous downward movement, the material is stamped... The plate is then stamped until the upper stamping seat 1009 and the lower stamping seat 1002 are closed, forming a circular groove between the first semicircular groove 200 and the second semicircular groove 300. This causes the plate to form a closed cylindrical shape under the stamping action. The hydraulic rod 5007 is activated to facilitate pushing the square plate 5005. Due to the clearance fit between the outer wall of the square plate 5005 and the inner wall of the square groove 5003, it moves stably within the square groove 5003, thereby enabling the stamping rod 5006 to move outward from the circular column 5002. When the stamping rod 5006 extends out of the circular hole 5004 under the pushing action, it performs a side opening operation on the cylindrical shell that has already been stamped under the action of the stamping through hole 1003. Since the lower stamping seat 1002 has an empty groove 400 inside, the waste material formed after punching accumulates in the empty groove 400 of the lower stamping seat 1002, making it easier for subsequent operators to clean up the waste material.
