Description
Technical Field
[0001] This utility model relates to the technical field of hardware clamp stamping equipment, specifically a hardware clamp stamping forming device with feeding function. Background Technology
[0002] The metal clamp stamping forming device is a specialized piece of equipment used in metal processing. It applies high pressure to metal sheets through a mold, causing them to plastically deform into clamps of a specific shape. It is commonly used for pipe fixing or structural connection. Its function is to efficiently and accurately stamp metal raw materials into pre-set ring or semi-ring clamp parts. It features fast forming, high consistency, and low cost, and is widely used in industries such as construction, power, and automobiles to meet the high precision requirements of complex hardware parts in mass production.
[0003] For example, a hardware clamp stamping forming device with feeding function disclosed in Chinese patent literature (publication number: CN112719066B) has a feeding mechanism. The stamping mechanism works by driving the feeding mechanism through the transmission mechanism. The addition of the feeding mechanism reduces the need for workers and improves the processing efficiency of the clamps.
[0004] However, when discharging, the arc-shaped pusher pushes out the forming clamp, and the workpiece falls directly into the material box. The lack of a buffer design means that the metal clamp will have a rigid collision with the box wall or the already piled workpieces during free fall, which can easily cause scratches, dents and other defects on the surface, especially for thinner forming workpieces.

The bottom rollers of the box facilitate transfer, reducing product collisions and deformation throughout the process. This achieves automated production without human intervention, is highly efficient, and protects product quality. Attached Figure Description

[0024] Reference Figures 1 to 6In this embodiment of the utility model, a hardware clamp stamping and forming device with feeding function includes: an operating table 1, which serves as the basic support structure of the entire device and supports various components; a stamping mechanism 2 is provided at one end of the operating table 1 for stamping raw materials; and a feeding and discharging mechanism 3 is provided at the other end of the operating table 1 for conveying raw materials and discharging finished parts.

The limiting rod 25 passes through the pressure plate 23 and is fixed to the mold base 4, providing guidance for pushing the pressure plate 23 and preventing deviation during stamping. At the same time, the spring 26 at the bottom of the pressure plate is compressed to buffer the impact force of stamping. The stamping block 24 cooperates with the mold base 4 to extrude the raw material into a clamp shape.
[0028] Reference Figure 1 , Figure 4 and Figure 5 The feeding mechanism 3 includes a box base 31, a motor 32 and a slider 33. The box base 31 is fixedly connected to the other end above the operating table 1, the motor 32 is fixedly connected to the middle of the head of the box base 31, and the slider 33 is slidably connected to the inside of the box base 31.
[0029] The lead screw 36 is threadedly connected to the slider 33. The other end of the lead screw 36 passes through the box base 31 and is fixedly connected to the output end of the motor 32. The motor 32 drives the lead screw 36 to rotate, and through the threaded transmission, it drives the slider 33 to slide laterally in the box base 31, so that the slide plate 34 moves to the vicinity of the feeding platform 7 at the edge of the operating table 1. Then, the motor 38 drives the gear 39 to rotate, thereby driving the feeding and pushing assembly 37 to rotate to pick up the material.
[0030] Take the feeding assembly 37, motor 2 38 and gear 1 39. Take the feeding assembly 37 and set it above one end of the slide plate 34. Motor 2 38 is fixedly connected to the other end above the slide plate 34. Gear 1 39 is fixedly connected to the output end of motor 2 38.

[0032] Reference Figure 1 , Figure 4 and Figure 5 The feeding and pushing assembly 37 includes a main shaft 371, a second gear 372, a double arm 373, and a connecting rod 374. The main shaft 371 is rotatably connected to one end of the slide plate 34 above the slide plate 34. The second gear 372 is fixedly connected to one end of the outer side of the main shaft 371. The double arm 373 is fixedly connected to one end of the main shaft 371 below the front side. The connecting rod 374 is fixedly connected to one end of the upper side. The second gear 372 meshes with the first gear 39.
[0033] Two sets of vacuum suction cups 376 are symmetrically arranged at both ends of the double arm 373. The other end of the supporting connecting rod 378 is fixedly connected to the connecting frame 377. Through gear two 372 meshing with gear one 39, the main shaft 371 rotates, and the double arm 373 swings above the feeding platform 7. The vacuum suction cups 376 at both ends adsorb the hardware materials on the feeding platform. Compared with push feeding, it is more suitable for thin hardware parts and avoids deformation of the material caused by pushing force. After successful adsorption, the rotation drives the double arm 373 and vacuum suction cups 376 to reset, and then the motor one 32 rotates in the opposite direction. The lead screw 36 drives the slider 3. 3. The slide plate 34 is moved towards the mold base 4. After the slide plate 34 moves to the tail of the box base 31, the material on the vacuum suction cup 376 is located directly above the mold base 4. The material is then put down by the vacuum suction cup 376. Then, the entire material feeding and pushing assembly 37 is moved away from the mold base 4. After the stamping is completed, the main shaft 371 is driven to rotate by the motor 2 38. The connecting rod 374 drives the arc-shaped push plate 375 to swing to the edge of the mold base. The slide plate 34 moves laterally. The arc-shaped push plate 375 pushes the forming clamp on the mold base 4 into the discharge channel 5 on the side of the operating table 1, realizing automatic unloading without manual intervention.
[0034] The arc-shaped push plate 375, vacuum suction cup 376, connecting frame 377, and support connecting rod 378 are fixedly connected to one end of the connecting rod 374, the vacuum suction cup 376 is fixedly connected to one end of the double arm rod 373, the connecting frame 377 is fixedly connected between the two arms of the double arm rod 373, and the support connecting rod 378 is fixedly connected to one end of the front of the main shaft 371.
[0035] Reference Figure 1 , Figure 3 and Figure 6 The receiving mechanism 6 includes a side baffle 61, a primary rubber inclined slide plate 62 and a secondary rubber inclined slide plate 63. The side baffle 61 is symmetrically and fixedly connected to the bottom of the operating table 1. The primary rubber inclined slide plate 62 and the secondary rubber inclined slide plate 63 are both fixedly connected between the two sets of side baffles 61. The inclined surfaces of the primary rubber inclined slide plate 62 and the secondary rubber inclined slide plate 63 are perpendicular to the discharge channel 5.
[0036] The receiving box 64 and rollers 65 are located below the secondary rubber inclined slide plate 63. The rollers 65 are fixedly connected to the bottom of the receiving box 64. The clamp falls along the discharge channel 5, first contacting the primary rubber inclined slide plate 62. The impact is reduced by the buffering effect of the rubber material. Then it slides down to the secondary rubber inclined slide plate 63 for further deceleration. The elasticity of the rubber material absorbs the impact force of the finished product falling, preventing the clamp from deforming due to free fall collision. Finally, the finished product slides along the secondary rubber inclined slide plate 63 into the receiving box 64 below. The rollers 65 at the bottom of the receiving box 64 facilitate movement and sorting, reducing the collision caused by the accumulation of finished products, and also facilitating the transfer to subsequent processes.
[0037] The working principle of this utility model is as follows:
[0038] Finally, the clamp falls along the discharge channel 5, first contacting the primary rubber inclined slide plate 62. The impact is reduced by the cushioning effect of the rubber material, and then it slides down to the secondary rubber inclined slide plate 63 for further deceleration. The elasticity of the rubber material absorbs the impact force of the finished product falling, preventing the clamp from deforming due to free fall collision. Finally, the finished product slides along the secondary rubber inclined slide plate 63 into the receiving box 64 below. The rollers 65 at the bottom of the receiving box 64 facilitate movement and sorting, reducing the collision caused by the accumulation of finished products, and at the same time facilitating the transfer to subsequent processes, completing the entire production process.
[0039] Step 3: Then, the main shaft 371 is driven to rotate by the motor 2 38, the connecting rod 374 drives the arc-shaped push plate 375 to swing to the edge of the mold base, the slide plate 34 moves laterally, and the arc-shaped push plate 375 pushes the forming clamp on the mold base 4 into the discharge channel 5 on the side of the operating table 1 to achieve automatic unloading without manual intervention.
[0040] Step 2: The cylinder 22 pushes the pressure plate 23 downward, causing the stamping block 24 fixed to the bottom of the pressure plate 23 to press down vertically. The limiting rod 25 passes through the pressure plate 23 and is fixed to the mold base 4, providing guidance for the pressure plate 23 and preventing it from shifting during stamping. At the same time, the spring 26 at the bottom of the pressure plate is compressed to buffer the impact of stamping. The stamping block 24 cooperates with the mold base 4 to extrude the raw material into a clamp shape, completing the stamping process.
[0041] Step 1: Motor 32 of the feeding mechanism 3 drives the lead screw 36 to rotate, which in turn drives the slider 33 to slide laterally within the box base 31 via threaded transmission. This moves the slide plate 34 to the vicinity of the feeding platform 7 at the edge of the operating table 1. Subsequently, motor 38 drives gear 39 to rotate, and gear 372 meshes to rotate the main shaft 371. The double arms 373 swing above the feeding platform 7, and the vacuum suction cups 376 at both ends adsorb the metal materials on the feeding platform. This method is more suitable for thin metal parts than push feeding, avoiding deformation of the materials caused by pushing force. After successful adsorption, the material rotates... The double-arm rod 373 and vacuum suction cup 376 are reset, and then the motor 32 rotates in the opposite direction. The lead screw 36 drives the slider 33 to move the slide plate 34 towards the mold base 4. The roller 35 at the bottom of the slide plate 34 rolls on the operating table surface to reduce movement resistance and reduce equipment wear, ensuring a smooth and wobbly movement. After the slide plate 34 moves to the tail of the box base 31, the material on the vacuum suction cup 376 is located directly above the mold base 4. The material is then lowered by the vacuum suction cup 376, and then the entire material picking and pushing assembly 37 is moved away from the mold base 4.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
