Description

Technical Field

[0001] This utility model relates to the field of metal stamping equipment technology, and in particular to a metal component stamping equipment. Background Technology

[0002] Metal components are widely used in many fields such as construction, machinery, and electrical engineering. They are composed of various types of metal profiles through welding, bolting, or riveting. Flat steel, as one of the common metal components, plays an important role in many fields. It can be used as finished steel products, as raw material for welded pipes, and as slab blanks for rolled thin plates. Flat steel is often formed by stamping during processing. Generally, hydraulic cylinders and stamping heads are used to stamp the flat steel to be formed on the forming die.

[0003] A search revealed Chinese patent CN212822040U, which discloses a flat steel stamping forming device. The device includes a worktable with supports on both sides of its top, the tops of which are fixedly connected by a top plate. Hydraulic cylinders are symmetrically mounted on the bottom of the top plate, and buffer mounting seats are fixedly connected to the output ends of the cylinders. The buffer mounting seats have buffer chambers, within which multiple stamping rods are movably mounted. The bottoms of the stamping rods slide through to the bottom of the buffer mounting seats and are fixedly mounted with punches. This invention provides the punches with excellent buffering performance, offering them a buffering time and space. This reduces the excessive reaction force directly and instantaneously applied to the punches by the flat steel to be formed during stamping, preventing damage due to the excessive strength of the flat steel material during direct downward stamping. This helps ensure the service life of the stamping heads and is suitable for widespread application.

[0004] The flat steel stamping forming device in the above patent has the following shortcomings: it is inconvenient to install and disassemble the punch and forming die. If different products need to be stamped on the production line, punches and dies of different shapes or sizes need to be replaced. If the process of replacing the stamping head is cumbersome or time-consuming, the downtime of the equipment will increase, which directly affects the production efficiency. Therefore, it is necessary to design a metal component stamping equipment to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a metal component stamping device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A metal component stamping device includes a base, a U-shaped frame fixedly connected to the top of the base, a horizontal plate arranged inside the U-shaped frame, and a plurality of first square plates fixedly connected to the bottom of the horizontal plate. Two first square plates at the same end form a group, and two first guide rods are arranged between the two first square plates at the same end. The first guide rods are fixedly connected to the first square plates, and the outer walls of the two first guide rods are fixedly connected to the same second square plate. First springs are arranged on both sides of the second square plate, and the first springs are sleeved on the first guide rods. Sliding plates are arranged on both sides of the second square plate, and the sliding plates are sleeved on the first guide rods. A guide rod is slidably connected to the sliding plate. A third square plate is fixedly connected to the bottom of the sliding plate. Insert rods are fixedly connected to the two third square plates on their adjacent sides. A fixing plate is fixedly connected to the bottom of the second square plate. L-shaped plates are fixedly connected to the bottom of both ends of the fixing plate. A second positioning rod is fixedly connected to the inner bottom wall of the L-shaped plate. A common retaining seat is provided within the two L-shaped plates. The retaining seat has holes adapted to the second positioning rods and insert rods. A punch head is fixedly connected to the bottom of the retaining seat. Adjacent sliding plates are connected together by a connecting plate, which is fixedly connected to the sliding plate at the edge. A fixing rod is fixedly connected to one side of the plate. An I-shaped wheel is fixedly connected to the fixing rod on the side away from the sliding plate. The I-shaped wheel is fitted onto a roller. Two guide plates are fixedly connected to the inner walls of both sides of the U-shaped frame. The roller is positioned on the side where the two guide plates are close to each other. Because a technique is used to move the insert rod closer to the card seat during the downward pressing process, the vertical position of the card seat is limited after the insert rod is inserted into the hole on the card seat. The second positioning rod limits the lateral position of the card seat, thus fixing the card seat and installing the pressing head. Raising the pressing head moves the insert rod away from the card seat, allowing the insert rod to exit the card seat. The limit switch can be released by moving the punch head out of the hole, allowing the holder to be removed and replaced with a punch head of a different shape or size. This effectively solves the problem mentioned in the background technology that the above-mentioned device is inconvenient to install and disassemble the punch head and forming die. If there are multiple products that need to be stamped on the production line, it is necessary to change punch heads and dies of different shapes or sizes. If the process of changing the punch head is cumbersome or time-consuming, the downtime of the equipment will increase, which will directly affect the production efficiency. This invention achieves the technical effect of facilitating the installation and disassembly of the punch head, improving the flexibility of the stamping equipment, simplifying operation, effectively reducing the time required for changeover, reducing equipment downtime, and ensuring production efficiency.

[0008] As a further embodiment of this utility model, a stamping die is provided at the bottom of each of the aforementioned stamping heads.

[0009] As a further embodiment of this utility model, the stamping die is provided with four first positioning rods, which are fixedly connected to the top of the base.

[0010] As a further embodiment of this utility model, four fourth guide rods are fixedly connected to the top of the base, the fourth guide rods pass through the horizontal plate, and the horizontal plate is slidably connected to the fourth guide rods.

[0011] As a further embodiment of this utility model, a plurality of third guide rods are provided through the horizontal plate, with each pair of third guide rods forming a group. The tops of the two third guide rods at the same end are fixedly connected to the same fifth square plate, and the bottoms of the two third guide rods at the same end are fixedly connected to the same pressure plate. The third guide rods are fitted with second springs, which are located at the bottom of the horizontal plate, and the fifth square plate is located at the top of the horizontal plate. Because the pressure plate and the first positioning rod cooperate to limit the position of the stamping die, when installing the stamping die, the lateral position of the stamping die can be limited by fitting the stamping die onto the first positioning rod, and the vertical position of the stamping die can be limited by pressing the pressure plate onto the stamping die, thus fixing the stamping die. The operation is simple and it is convenient to install and disassemble the stamping die.

[0012] As a further embodiment of this utility model, a number of fourth square plates are fixedly connected to the bottom of the horizontal plate, with each pair of fourth square plates forming a group. The two fourth square plates at the same end are fixedly connected to the same second guide rod on the side that is close to each other. The second guide rod passes through two fixed rods at the same end, and the fixed rods are slidably connected to the second guide rod.

[0013] As a further embodiment of this utility model, two hydraulic cylinders are provided on the top of the horizontal plate, the output end of the hydraulic cylinders is fixedly connected to the horizontal plate, and the base of the hydraulic cylinders is fixedly connected to the top inner wall of the U-shaped frame.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention addresses the issue of the insertion rod moving closer to the card holder during the lowering of the stamping head. By employing a technique that allows the insertion rod to move closer to the card holder during the lowering process, the vertical position of the card holder is limited after the insertion rod is inserted into the hole on the card holder. The second positioning rod then limits the lateral position of the card holder, thus securing the card holder and allowing the stamping head to be installed. Raising the stamping head moves the insertion rod away from the card holder, allowing it to exit the hole and release the limiting mechanism. This allows the card holder to be removed and replaced with a stamping head of a different shape or size. This effectively solves the problem of inconvenient installation and disassembly of the stamping head and forming die in the background art. Furthermore, if multiple products need stamping on the production line, different shapes or sizes of stamping heads and dies need to be changed. If the process of changing stamping heads is cumbersome or time-consuming, equipment downtime will increase, directly affecting production efficiency. This invention facilitates the installation and disassembly of stamping heads, improves the flexibility of stamping equipment, simplifies operation, effectively reduces the time required for replacement, minimizes equipment downtime, and ensures production efficiency.

[0016] This utility model employs a technique that uses a pressure plate and a first positioning rod to limit the position of the stamping die. Therefore, when installing the stamping die, simply placing the stamping die on the first positioning rod limits its lateral position, and pressing the pressure plate onto the stamping die limits its vertical position, thus fixing the stamping die in place. This method is simple to operate and facilitates the installation and disassembly of the stamping die. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and implementing regulations.

[0024] Reference Figure 1 - Figure 4A metal component stamping device includes a base 1, a U-shaped frame 2 fixedly connected to the top of the base 1, a horizontal plate 5 arranged inside the U-shaped frame 2, and several first square plates 6 fixedly connected to the bottom of the horizontal plate 5. Two first square plates 6 at the same end form a group, and two first guide rods 7 are arranged between the two first square plates 6 at the same end. The first guide rods 7 are fixedly connected to the first square plates 6, and the outer walls of the two first guide rods 7 are fixedly connected to the same second square plate 8. First springs 10 are arranged on both sides of the second square plate 8 and are sleeved on the first guide rods 7. Sliding plates 9 are arranged on both sides of the second square plate 8 and are sleeved on the first guide rods 7. A first guide rod 7 is slidably connected to a sliding plate 9. A third square plate 11 is fixedly connected to the bottom of the sliding plate 9. Insert rods 12 are fixedly connected to the two third square plates 11 on their adjacent sides. A fixing plate 13 is fixedly connected to the bottom of a second square plate 8. L-shaped plates 14 are fixedly connected to the bottom of both ends of the fixing plate 13. A second positioning rod 15 is fixedly connected to the inner bottom wall of the L-shaped plate 14. The two L-shaped plates 14 are provided with the same card seat 16. The card seat 16 has holes that are adapted to the second positioning rod 15 and the insert rod 12. A punch head 17 is fixedly connected to the bottom of the card seat 16. Adjacent sliding plates 9 are connected together by a connecting plate 18. The connecting plate 18 is fixedly connected to the sliding plate 9. A fixing rod 19 is fixedly connected to one side of the sliding plate 9 at the edge. An I-shaped wheel 20 is fixedly connected to the fixing rod 19 on the side away from the sliding plate 9. The I-shaped wheel 20 is sleeved on the roller 21. Two guide plates 22 are fixedly connected to the inner walls of both sides of the U-shaped frame 2. The roller 21 is located on the side where the two guide plates 22 are close to each other. Due to the use of a technology that allows the insertion rod to move closer to the card seat during the downward pressing head process, the vertical position of the card seat can be limited after the insertion rod is inserted into the hole on the card seat. The second positioning rod limits the lateral position of the card seat, thus fixing the card seat and installing the pressing head. Raising the pressing head allows the insertion rod to move away from the card seat. The device allows the insert rod to be moved out of the hole on the holder, thus releasing the limit and allowing the holder to be removed for replacement with a stamping head of a different shape or size. This effectively solves the problem mentioned in the background art where the aforementioned device is inconvenient for installing and disassembling the punch and forming die holder. If multiple products need to be stamped on the production line, different shapes or sizes of punches and dies need to be changed. If the process of changing the stamping head is cumbersome or time-consuming, the downtime of the equipment will increase, which directly affects the production efficiency. This device facilitates the installation and disassembly of the stamping head, improves the flexibility of the stamping equipment, simplifies operation, effectively reduces the time required for changeover, reduces equipment downtime, and ensures production efficiency.

[0025] In this embodiment, a stamping die 4 is provided at the bottom of each of the several stamping heads 17.

[0026] In this embodiment, four first positioning rods 3 are provided on the stamping die 4. By fitting the stamping die 4 onto the first positioning rods 3, the lateral position of the stamping die 4 can be limited, ensuring the stability of the stamping die 4 in the lateral position. The first positioning rods 3 are fixedly connected to the top of the base 1. By providing the first positioning rods 3, it is convenient to disassemble and replace the stamping die 4, thereby improving the replacement efficiency of the stamping die 4 and adapting to the stamping processing requirements of different shapes or sizes.

[0027] In this embodiment, four fourth guide rods 30 are fixedly connected to the top of the base 1. The fourth guide rods 30 pass through the horizontal plate 5. When the horizontal plate 5 moves, it will move along the fourth guide rods 30 to ensure the stability of the horizontal plate 5 when it moves. The horizontal plate 5 is slidably connected to the fourth guide rods 30.

[0028] In this embodiment, a plurality of third guide rods 26 are threaded through the horizontal plate 5. Each pair of third guide rods 26 forms a group. The tops of two third guide rods 26 at the same end are fixedly connected to the same fifth square plate 27, and the bottoms of two third guide rods 26 at the same end are fixedly connected to the same pressure plate 28. Second springs 29 are sleeved on the third guide rods 26. When the horizontal plate 5 descends, the third guide rods 26, the fifth square plate 27, and the pressure plate 28 all descend accordingly. If the horizontal plate 5 continues to descend after the pressure plate 28 contacts the tops of both ends of the stamping die 4, the horizontal plate 5 will compress the second springs 29, causing the second springs 29 to contract. The reaction force of spring 29 causes pressure plate 28 to press onto stamping die 4, fixing the vertical position of stamping die 4. Second spring 29 is set at the bottom of horizontal plate 5, and fifth square plate 27 is set at the top of horizontal plate 5. Because the pressure plate and first positioning rod cooperate to limit the position of stamping die, when installing stamping die, the horizontal position of stamping die can be limited by putting stamping die on the first positioning rod. By pressing pressure plate onto stamping die, the vertical position of stamping die can be limited, thus fixing stamping die. The operation is simple and convenient for installing and disassembling stamping die.

[0029] In this embodiment, a number of fourth square plates 24 are fixedly connected to the bottom of the horizontal plate 5. Every two fourth square plates 24 form a group. The two fourth square plates 24 at the same end are fixedly connected to the same second guide rod 23 on the side that is close to each other. The second guide rod 23 passes through two fixed rods 19 at the same end. When the fixed rod 19 moves, it will move along the second guide rod 23 to ensure the stability of the fixed rod 19 when it moves. The fixed rod 19 is slidably connected to the second guide rod 23.

[0030] In this embodiment, two hydraulic cylinders 25 are provided on the top of the horizontal plate 5. The output end of the hydraulic cylinder 25 is fixedly connected to the horizontal plate 5, and the base of the hydraulic cylinder 25 is fixedly connected to the top inner wall of the U-shaped frame 2.

[0031] Working principle: When using this device, the horizontal plate 5 is pushed down by the downward movement of the output end of the hydraulic cylinder 25. The horizontal plate 5 drives the first square plate 6 and the second square plate 8 to descend. The first square plate 6 and the second square plate 8 drive the first guide rod 7 to descend. The first guide rod 7 drives the sliding plate 9 to descend. The sliding plate 9 drives the third square plate 11 to descend. The third square plate 11 drives the insert rod 12 to descend. The insert rod 12 drives the clamping seat 16 to descend. The clamping seat 16 drives the stamping head 17 to descend for stamping. This allows for the stamping of flat steel to be formed on the stamping die 4. Different shapes or sizes of stamping heads are required. When the stamping head 17 and stamping die 4 are replaced, the horizontal plate 5 is raised so that the pressure plate 28 no longer contacts the stamping die 4, thus releasing the vertical restriction on the stamping die 4. The stamping die 4 can then be removed and replaced with a stamping die 4 of a different shape or size. The horizontal plate 5 continues to rise until the roller 21 moves to the top inclined surface of the guide plate 22 and continues to rise. The first spring 10, which has been contracted, will then extend, allowing the two sliding plates 9 to move away from each other. This allows the two insert rods 12 to move away from each other and be pulled out of the hole in the card holder 16, thus releasing the restriction on the card holder 16. The card holder 16 can then be removed. The stamping head 17 can be removed and replaced. The stamping head 17 and the mounting bracket 16 are used together. The mounting bracket 16 and the stamping head 17 are fixed together during production, so there is no need to fix the mounting bracket 16 and the stamping head 17 during installation. The mounting bracket 16 on the new stamping head 17 is put onto the two second positioning rods 15, which limits the lateral position of the mounting bracket 16. Then, the output end of the hydraulic cylinder 25 is lowered a short distance, which causes the horizontal plate 5 to fall. When the sliding plate 9 falls, it will drive the fixing rod 19 to fall. The fixing rod 19 will drive the I-shaped wheel 20 to fall. The I-shaped wheel 20 will drive the roller 2 As the plate descends, roller 21 moves along the inclined surface of guide plate 22. The two rollers 21 at the same end move closer to each other, which in turn brings the two fixed rods 19 closer together. This allows the sliding plate 9 to move along the first guide rod 7 and approach the second square plate 8. The sliding plate 9 then drives the third square plate 11 to approach the card holder 16. The third square plate 11 then drives the insert rod 12 to move closer to the card holder 16 until it is inserted into the hole on the card holder 16. This limits the vertical position of the card holder 16, thus fixing the card holder 16 and installing the stamping head 17, allowing the flat steel stamping operation to continue.
