Description

Technical Field

[0001] The utility model relates to the technical field of hardware fitting processing, and particularly relates to a stamping device for hardware fitting processing. Background Art

[0002] Hardware fittings refer to machine parts or components made of hardware, as well as some small hardware products. They can be used alone or as auxiliary tools for other equipment. There are a wide variety of hardware fittings, which are widely used in various fields, including but not limited to construction, automobiles, homes, machinery, electronics, etc. The manufacturing process of hardware fittings involves multiple links, such as stamping, casting, forging, etc. During the stamping process, problems such as burrs and edge gaps, adhesion scratches and friction, foreign matter mixing and unevenness, punching size deviation, wire offset and extrusion, bending and stress unevenness, plastic deformation of materials, and die accuracy and adjustment may be encountered. To solve these problems, manufacturers need to continuously optimize process parameters, adjust die structures, select suitable materials, and strengthen quality control to ensure the quality and performance of hardware fittings.

[0003] In the prior art, during the processing of hardware fittings, stamping equipment is used to stamp metal plates into various fitting shapes. However, for traditional stamping equipment, when stamping metal plates into fittings, it requires workers to manually feed the materials and limit their positions. This method is relatively dangerous. During the stamping process of the metal plate, its tail end may warp, and the working intensity is relatively high. There may be a situation of deviation during the stamping process. Also, when there are dust and impurities on the metal plate and they are not cleaned, stamping will cause damage to the stamped fittings, affecting the quality.

[0004] Therefore, a stamping device for hardware fitting processing is proposed. Content of the Utility Model

[0024] Such as Figure 1-2As shown in the figure, a stamping device for processing hardware fittings includes a workbench 1. A stamping assembly 2 is arranged on the top of the workbench 1. Two supporting platforms 3 are arranged on the top of the workbench 1. A pushing mechanism 4 for feeding a metal plate and cleaning the upper and lower surfaces is arranged on the top of the workbench 1. A positioning mechanism 5 for clamping and positioning the metal plate is arranged at the bottom of the workbench 1. A limiting mechanism 6 for pressing down the metal plate to prevent warping is arranged on the positioning mechanism 5. A fixing plate 7 is arranged on one side of the workbench 1. A control panel 8 is arranged on one side of the fixing plate 7. In this embodiment, when in use, first place the metal plate on the two supporting platforms 3. Control the positioning mechanism 5 through the control panel 8 to clamp and position the metal plate, so as to avoid deviation during the stamping process of the stamping assembly 2 on the metal plate. Control the limiting mechanism 6 through the control panel 8 to press the metal plate onto the two supporting platforms 3, so as to avoid warping at the tail end during the stamping process of the stamping assembly 2 on the metal plate, and does not affect the pushing of the metal plate by the pushing mechanism 4. Then control the pushing mechanism 4 through the control panel 8 to push the metal plate onto the stamping assembly 2. During the pushing process, the pushing mechanism 4 cleans the dust and impurities on the upper and lower surfaces of the metal plate. When the pushing mechanism 4 pushes the metal plate onto the stamping assembly 2, control the stamping assembly 2 through the fixing plate 7 to stamp the metal plate into shape. With the cooperation of the pushing mechanism 4 and the stamping assembly 2, continuous stamping work is carried out on the metal plate, so as to stably stamp the metal plate into the shape of a fitting, without manual feeding by workers, reducing the workload of workers, simultaneously removing the dust and impurities on the metal plate, improving the stamping quality, and having high safety and strong practicability.

[0025] As Figure 1-2 shown, the pushing mechanism 4 includes a one-way lead screw 402. A rectangular notch 401 runs through the top of the workbench 1 between the two supporting platforms 3. The one-way lead screw 402 is rotatably installed inside the rectangular notch 401. A rectangular plate 403 is threadedly installed on the outer wall of the one-way lead screw 402, and the rectangular plate 403 is slidably installed on the inner wall of the rectangular notch 401. A motor 404 is installed on the left side of the one-way lead screw 402, and the motor 404 is installed on the left side of the workbench 1. In this embodiment, by starting the motor 404, the one-way lead screw 402 is driven to rotate, so that the rectangular plate 403 slides horizontally in the rectangular notch 401, pushing the metal plate on the two supporting platforms 3, thereby feeding the metal plate onto the stamping assembly 2 for stamping work.

[0026] As Figure 2 shown, two fixing rods 405 are symmetrically installed on the top of the workbench 1. Two cleaning brushes 406 are installed between the two fixing rods 405. In this embodiment, when the metal plate moves forward, it will pass between the two cleaning brushes 406, and the two cleaning brushes 406 clean the upper and lower surfaces of the metal plate to remove the impurities and dust on its surface, improving the stamping quality.

[0027] AsFigure 1 , Figure 3 As shown in Figure 3 , the positioning mechanism 5 includes a support plate 501, which is installed at the bottom of the workbench 1. Two limiting grooves are formed in the bottom of the support plate 501. Limiting blocks 502 are slidably installed on the inner walls of the two limiting grooves. A shaft column 504 is rotatably installed at the bottom of the support plate 501. A gear 505 is installed on the outer wall of the shaft column 504. Rack bars 503 are installed on the surfaces of the two limiting blocks 502, and the two rack bars 503 are engaged with the gear 505. An installation frame 507 is installed at the bottom of the workbench 1. A second motor 506 is installed on the surface of the installation frame 507, and the output end of the second motor 506 is installed at the bottom of the shaft column 504. In this embodiment, by starting the second motor 506, the shaft column 504 and the gear 505 are driven to rotate, and the gear 505 drives the two rack bars 503 to move, so that the two limiting blocks 502 slide in the two limiting grooves, moving closer to or away from each other, thereby adjusting the distance between the two limiting blocks 502.

[0028] As Figure 3 shown in Figure 3 , connecting rods 508 are installed on the surfaces of the two limiting blocks 502. Support rods 509 are installed on the surfaces of the two connecting rods 508. Positioning plates 510 are installed on the surfaces of the two support rods 509. In this embodiment, when the two limiting blocks 502 move closer to each other, the two connecting rods 508 and the two support rods 509 are driven to move accordingly, and the two positioning plates 510 clamp and position the two sides of the metal plate, thereby stamping and positioning the metal plate, avoiding offset during the stamping process of the metal plate and affecting the stamping quality.

[0029] As Figure 1 , Figure 3 shown in Figure 1 and Figure 3 , the limiting mechanism 6 includes two cylinders 601, which are installed at the tops of the support rods 509. L-shaped rods 602 are installed at the tops of the two cylinders 601. Fixed shells 603 are installed at the bottoms of the two L-shaped rods 602. A plurality of rollers 604 are rotatably installed inside the two fixed shells 603. In this embodiment, when the two support rods 509 move closer to each other, the two cylinders 601 move accordingly. By starting the two cylinders 601, the two L-shaped rods 602, the two fixed shells 603 and the plurality of rollers 604 are driven to move downward, pressing the metal plate against the two support platforms 3. When the metal plate moves forward, it will drive the plurality of rollers 604 to rotate, thereby limiting the metal plate and avoiding warping during the stamping process and causing potential safety hazards.

[0030] In summary, during use, first place the metal plate on the two support platforms 3. Control the positioning mechanism 5 through the control panel 8 to clamp and position the metal plate, preventing offset during the stamping process of the stamping component 2.

Then, control the pushing mechanism 4 through the control panel 8 to push the metal plate onto the stamping component 2. During the pushing process, the pushing mechanism 4 cleans dust and impurities from the upper and lower surfaces of the metal plate. When the pushing mechanism 4 pushes the metal plate onto the stamping component 2, control the stamping component 2 to stamp and form the metal plate through the fixing plate 7. With the cooperation of the pushing mechanism 4 and the stamping component 2, continuous stamping work is carried out on the metal plate, thus stably stamping the metal plate into the shape of a fitting. There is no need for manual feeding by workers, reducing the workload of workers. At the same time, dust and impurities on the metal plate are removed, improving the stamping quality, and having high safety and strong practicability. By starting the first motor 404, drive the one-way lead screw 402 to rotate, causing the rectangular plate 403 to slide horizontally in the rectangular notch 401, pushing the metal plate on the two support platforms 3, thereby feeding the metal plate to the stamping component 2 for stamping work. When the metal plate moves forward, it will pass between the two cleaning brushes 406, and the two cleaning brushes 406 clean the upper and lower surfaces of the metal plate, removing impurities and dust on its surface, improving the stamping quality. By starting the second motor 506, drive the shaft column 504 and the gear 505 to rotate, and the gear 505 drives the two toothed rods 503 to move, causing the two limit blocks 502 to slide in the two limit grooves, moving closer to or away from each other, thereby adjusting the distance between the two limit blocks 502. When the two limit blocks 502 move closer to each other, drive the two connecting rods 508 and the two support rods 509 to move accordingly, and the two positioning plates 510 clamp and position the two sides of the metal plate, thereby positioning the metal plate during stamping, preventing offset during the stamping process of the metal plate and affecting the stamping quality. When the two support rods 509 move closer to each other, the two cylinders 601 move accordingly. Start the two cylinders 601 to drive the two L-shaped rods 602, the two fixed shells 603, and the multiple rollers 604 to move downward, pressing the metal plate onto the two support platforms 3. When the metal plate moves forward, it will drive the multiple rollers 604 to rotate, thereby limiting the metal plate and preventing warping during stamping, which may cause potential safety hazards.
