Description

Technical Field

[0001] This utility model relates to the field of metal sheet stamping technology, specifically a metal sheet stamping device. Background Technology

[0002] Thin metal sheets typically refer to metal sheets with a thickness between 0.2 mm and 4.0 mm, belonging to the category of thin sheet materials. A stamping device is a type of equipment used for metal processing. It is mainly used to apply external force to sheet metal, strip, tube, and profile through a press and mold, causing the material to undergo plastic deformation or separation, thereby obtaining workpieces of the required shape and size. A thin metal sheet stamping device is a type of equipment used for stamping thin metal sheets.

[0003] For example, the metal sheet stamping device disclosed in Chinese Patent CN220028351U has an ejection mechanism. After the stamping plate forms the sheet material, the second cylinder drives the second piston rod and moves the top plate upward to eject the stamped sheet material. This is faster and more efficient than manual removal. The push-out mechanism pushes out the stamped sheet material. After the ejection mechanism ejects the stamped sheet material, the third cylinder drives the third piston rod and moves the push plate to push out the stamped sheet material. This speeds up the process and avoids the safety hazards of manual operation.

[0004] While this structure can stamp thin metal sheets, it is inconvenient to fix the sheets in place. When the stamping plate moves upward, its outer wall can easily get stuck on the sheet, causing it to be lifted up. This requires operators to remove the material, affecting the stamping efficiency. Therefore, we propose a thin metal sheet stamping device that can fix the sheet in place, preventing it from getting stuck on the outer wall of the stamping plate and thus improving stamping efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a metal sheet stamping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal sheet stamping device, including a stamping table, a cylinder arranged above the stamping table, a stamping plate fixedly installed at the end of the cylinder, and a processing component arranged below the cylinder, the processing component including a fixing component arranged on the top surface of the stamping table, and an auxiliary component arranged above the fixing component.

[0007] Preferably, the fixing assembly includes a bracket fixedly installed on the top surface of the stamping table, a horizontal plate fixedly installed at the end of the bracket, a counter-threaded rod rotatably connected inside the horizontal plate, a sleeve block sleeved on the outer wall of the counter-threaded rod, a connecting plate hinged to the bottom of the sleeve block, a push plate hinged to the end of the connecting plate away from the sleeve block, a limit rod fixedly installed on the top surface of the push plate, a sleeve fixedly installed at the bottom of the push plate, a first magnetic block fixedly installed on the inner wall of the sleeve, a second magnetic block slidably arranged inside the sleeve, and a pressure rod fixedly installed on the side wall of the second magnetic block.

[0008] Preferably, the auxiliary component includes a support plate fixedly installed on the top surface of the stamping plate, a slide rod sleeved inside the support plate, a spring sleeved on the outer wall of the slide rod, and a pressure frame fixedly installed at the end of the slide rod.

[0009] Preferably, the first magnetic block and the second magnetic block are magnetically repulsive, and the outer wall of the second magnetic block is slidably disposed with respect to the inside of the sleeve. Under the restriction of magnetic repulsion, the pressure rod is made to fit and clamp the metal sheet according to its shape.

[0010] Preferably, the end of the pressure rod away from the second magnetic block is made of rubber, and the outer wall of the pressure rod is slidably disposed with the inside of the sleeve. Under the constraint of the rubber material, the coefficient of friction between the pressure rod and the thin metal plate can be increased.

[0011] Preferably, the outer wall of the sleeve block is slidably disposed with respect to the inner side of the horizontal plate. There are two sleeve blocks, which are symmetrically distributed around the center line of the horizontal plate. Under their constraint, the rotating opposing threaded rod drives the sleeve block to move.

[0012] Preferably, the outer wall of the limiting rod is slidably disposed with respect to the inside of the horizontal plate, and there are two limiting rods symmetrically distributed around the center line of the top surface of the push plate. Under the restriction of the two limiting rods, the up and down movement of the push plate is more stable.

[0013] Preferably, one end of the spring is fixedly installed to the inner side of the support plate, and the other end of the spring away from the support plate is fixedly installed to the top surface of the pressure frame. Under the elastic action of the spring, pressure can be applied to the pressure frame that is in contact with the metal sheet, so as to avoid misalignment of the metal sheet during stamping.

[0014] Preferably, the pressure frame is slidably disposed inside the outer wall of the stamping plate, and the bottom of the pressure frame is made of rubber. Under the restriction of the pressure frame, the waste material after stamping can be prevented from getting stuck on the outer wall of the stamping plate, and the pressure frame with the rubber bottom can prevent the metal sheet from sliding.

[0015] Preferably, there are two support plates, symmetrically distributed around the center line of the top surface of the stamping plate. Under the constraint of the support plates, the slide rod can stably drive the pressure frame to slide.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This metal sheet stamping device consists of a fixed assembly as one component. When metal sheets need to be stamped, it is placed on the top surface of the stamping table. The opposing threaded rod is rotated. Due to the sliding arrangement between the outer wall of the sleeve block and the interior of the horizontal plate, the rotating opposing threaded rod drives the two sleeve blocks to move in opposite directions. Since the sleeve blocks are hinged to the push plate via a connecting plate, and a limiting rod fixedly installed on the top surface of the push plate slides within the horizontal plate, the push plate moves stably downwards under its constraint. The push plate drives the sleeve, the first magnetic block, the second magnetic block, and the pressure rod downwards, causing the pressure rod to... The rod contacts the thin metal sheet. Since each pressure rod slides independently, it can press according to the shape of the thin metal sheet. Due to the magnetic repulsion between the first and second magnetic blocks, a pushing force is applied to the pressure rod under its constraint, clamping the thin metal sheet. This structure can fix the thin metal sheet on the top surface of the stamping table, and under the constraint of the independently sliding pressure rod, it can press according to the shape of the thin metal sheet (the stamping table, cylinder, stamping plate, pushing mechanism and ejection mechanism are existing disclosed technologies in the prior art, so their structures are not fully described in this case).

[0018] 2. This metal sheet stamping device consists of an auxiliary component. When stamping a metal sheet is required, the sheet is fixed by a fixing component. At this time, the cylinder pushes the stamping plate towards the metal sheet, so that the bottom of the pressure frame contacts the metal sheet. As the stamping plate descends, the support plate fixedly installed on the top surface of the stamping plate slides on the outer wall of the slide rod, compressing the spring sleeved on the outer wall of the slide rod. The spring applies pressure to the top surface of the pressure frame, and the pressure frame assists in pressing the metal sheet. After stamping is completed, the stamping plate moves upward. Under the restriction of the pressure frame, stamping waste can be prevented from getting stuck on the outer wall of the stamping plate. This structure can assist in pressing the metal sheet and prevent waste from getting stuck on the outer wall of the stamping plate. Attached Figure Description

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] Example 1: A preferred embodiment of the metal sheet stamping device provided by this utility model is as follows: Figures 1 to 6 As shown: A metal sheet stamping device, including a stamping table 1;

[0028] A cylinder 2 is installed above the stamping table 1;

[0029] A stamping plate 3 is fixedly installed at the end of cylinder 2;

[0030] The machining assembly 4 is located below the cylinder 2. The machining assembly 4 includes a fixing assembly 41 located on the top surface of the stamping table 1. The fixing assembly 41 includes a bracket 411 fixedly installed on the top surface of the stamping table 1. A horizontal plate 412 is fixedly installed at the end of the bracket 411. A counter-threaded rod 413 is rotatably connected inside the horizontal plate 412. A sleeve block 414 is sleeved on the outer wall of the counter-threaded rod 413. A connecting plate 415 is hinged to the bottom of the sleeve block 414. A push plate 416 is hinged to the end of the connecting plate 415 away from the sleeve block 414. A limit rod 417 is fixedly installed on the top surface of the push plate 416. A sleeve 418 is fixedly installed at the bottom of the push plate 416. A first magnetic block 419 is fixedly installed on the inner wall of the sleeve 418. A second magnetic block 420 is slidably arranged inside the sleeve 418. A pressure rod 421 is fixedly installed on the side wall of the second magnetic block 420.

[0031] In this embodiment, when it is necessary to stamp a thin metal sheet, it is placed on the top surface of the stamping table 1, and the opposing threaded rod 413 is rotated. Due to the sliding arrangement between the outer wall of the sleeve block 414 and the interior of the horizontal plate 412, the rotating opposing threaded rod 413 drives the two sleeve blocks 414 to move in opposite directions. Since the sleeve block 414 is hinged to the push plate 416 through the connecting plate 415, and the limiting rod 417 fixedly installed on the top surface of the push plate 416 is slidingly arranged with the interior of the horizontal plate 412, the push plate 416 moves steadily downward under its constraint. The push plate 416 drives the sleeve 418, the first magnetic block 419, the second magnetic block 420 and the pressure rod 421 to move downward. The downward movement causes the pressure rod 421 to contact the metal sheet. Since each pressure rod 421 slides independently, it can press according to the shape of the metal sheet. Due to the magnetic repulsion between the first magnetic block 419 and the second magnetic block 420, a pushing force is applied to the pressure rod 421 under its constraint, thus clamping the metal sheet. This structure can fix the metal sheet on the top surface of the stamping table 1, and under the constraint of the independently sliding pressure rod 421, it can press according to the shape of the metal sheet (the stamping table 1, cylinder 2, stamping plate 3, pushing mechanism and ejection mechanism are existing disclosed technologies in the prior art, so their structures are not fully described in this case).

[0032] The first magnetic block 419 and the second magnetic block 420 are magnetically repulsive. The outer wall of the second magnetic block 420 is slidably disposed with the inside of the sleeve 418. Under the restriction of magnetic repulsion, the pressure rod 421 is clamped in accordance with the shape of the thin metal plate.

[0033] Among them, the end of the pressure rod 421 away from the second magnet 420 is made of rubber. The outer wall of the pressure rod 421 is slidably set inside the sleeve 418. Under the restriction of the rubber material, the coefficient of friction between the pressure rod 421 and the metal sheet can be increased.

[0034] Among them, the outer wall of the sleeve block 414 is slidably disposed with the inner side of the horizontal plate 412. There are two sleeve blocks 414, which are symmetrically distributed with respect to the center line of the horizontal plate 412. Under their restriction, the rotating opposing threaded rod 413 drives the sleeve block 414 to move.

[0035] Among them, the outer wall of the limiting rod 417 is slidably set inside the horizontal plate 412. There are two limiting rods 417, which are symmetrically distributed around the center line of the top surface of the push plate 416. Under the restriction of the two limiting rods 417, the up and down movement of the push plate 416 is more stable.

[0036] Example 2: Based on Example 1, a preferred embodiment of the metal sheet stamping device provided by this utility model is as follows: Figures 1 to 6 As shown: The auxiliary component 43 includes a support plate 431 fixedly installed on the top surface of the stamping plate 3. A slide rod 432 is sleeved inside the support plate 431. A spring 433 is sleeved on the outer wall of the slide rod 432. A pressure frame 434 is fixedly installed at the end of the slide rod 432.

[0037] In this embodiment, when it is necessary to stamp the thin metal sheet, the sheet is fixed by the fixing component 41. At this time, the cylinder 2 pushes the stamping plate 3 to move towards the thin metal sheet, so that the bottom of the pressure frame 434 contacts the thin metal sheet. As the stamping plate 3 descends, the support plate 431 fixedly installed on the top surface of the stamping plate 3 slides on the outer wall of the slide rod 432 and compresses the spring 433 sleeved on the outer wall of the slide rod 432, so that the spring 433 applies pressure to the top surface of the pressure frame 434. The pressure frame 434 assists in pressing the thin metal sheet. After stamping is completed, the stamping plate 3 moves upward. Under the restriction of the pressure frame 434, the stamping waste can be prevented from getting stuck on the outer wall of the stamping plate 3. This structure can assist in pressing the thin metal sheet and at the same time prevent waste from getting stuck on the outer wall of the stamping plate 3.

[0038] One end of the spring 433 is fixedly installed on the inner side of the support plate 431, and the other end of the spring 433 away from the support plate 431 is fixedly installed on the top surface of the pressure frame 434. Under the elastic action of the spring 433, pressure can be applied to the pressure frame 434 that is in contact with the metal sheet to prevent the metal sheet from being misaligned during stamping.

[0039] The pressure frame 434 is slidably disposed inside the outer wall of the stamping plate 3. The bottom of the pressure frame 434 is made of rubber. Under the restriction of the pressure frame 434, the waste material after stamping can be prevented from getting stuck on the outer wall of the stamping plate 3. Under the restriction of the pressure frame 434 with the rubber material at the bottom, the thin metal plate can be prevented from sliding.

[0040] There are two support plates 431, which are symmetrically distributed around the center line of the top surface of the stamping plate 3. Under the restriction of the support plates 431, the slide rod 432 stably drives the pressure frame 434 to slide.

[0041] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
