Description

Technical Field

[0001] This utility model relates to the field of disc feeders, specifically to a disc feeder for a stamping press. Background Technology

[0002] Narrow steel strips, as raw materials for stamped parts, are transported in bundles. During the stamping production process, it is necessary to unload the narrow steel strips. The traditional unloading method is to use an internal tensioning mechanism to tension the inside of the metal coil, and then set the rotation speed of the internal tensioning mechanism according to the feeding speed of the feeding system.

[0003] While existing disc feeders can convey and support narrow steel strips, the strip needs to rotate 90 degrees before reaching the guide rollers. To ensure smooth operation, the strip needs a relatively long contact with the ground, which can cause sand and gravel to adhere to it, potentially damaging the stamping die during subsequent pressing. Conversely, if this section is too short, the rotation will generate significant pressure, easily leading to strip deformation. Therefore, a disc feeder for stamping presses is needed that avoids the strip contacting the ground and prevents bending even when the distance from the coil to the guide rollers is short. Utility Model Content

[0004] The purpose of this utility model is to provide a disc feeder for a stamping machine.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A disc feeder for a stamping press is provided, comprising a frame, a height adjusting rod, two bent rods, and a circular feeding disc rotatably mounted on the frame. A rotary drive mechanism for rotating the circular feeding disc is provided inside the frame. A rotatable rotating block is provided on the vertical rod of the frame. The height adjusting rod is slidably mounted on the rotating block. A counterweight is fixedly mounted on one side of the rotating block. A guide roller is fixedly mounted on the bottom end of the height adjusting rod. The two bent rods are vertically raised and lowered on the vertical rod via connectors. Each bent rod is inclined upward from right to left.

[0007] Furthermore, the two curved rods are staggered, with the upper curved rod being closer to the guide roller than the lower curved rod.

[0008] Furthermore, the connector includes a collar, an extension shaft, and an angle adjustment mechanism. The collar is sleeved on the outer edge of the vertical rod, and a screw is engaged on the outer edge of the collar. The end of the screw abuts against the vertical rod. One end of the extension shaft is fixedly connected to the collar, and the other end of the extension shaft is fixedly connected to the angle adjustment mechanism. The bent rod is fixedly mounted on the rotating plate of the angle adjustment mechanism.

[0009] Furthermore, the angle adjustment mechanism includes bolts, a support plate, and two annular rubber pads. The support plate is fixedly installed on the extension shaft, and the rotating plate is rotatably connected to the support plate by bolts. There are two rotating plates, which are clamped on both sides of the support plate. Annular rubber pads are provided on the side of the two rotating plates that are in contact with the support plate.

[0010] Furthermore, two stop levers are fixedly installed on the frame, and a height adjustment lever is located between the two stop levers. A pressure sensor is fixedly installed on the frame. When the height adjustment lever contacts the stop lever on the right, the outer edge of the height adjustment lever is pressed against the sensing end of the pressure sensor.

[0011] Furthermore, a through hole is provided in the middle of the rotating block for the height adjustment rod to slide, and a limit block is clamped on the outer edge of the height adjustment rod, with the bottom of the limit block fitting against the top of the rotating block.

[0012] Furthermore, a counterweight block is fixedly installed at the end of the counterweight rod.

[0013] Furthermore, a connecting ring is detachably mounted on the side of the guide roller, and a hook extending toward the guide roller is fixedly provided on the connecting ring.

[0014] The beneficial effects of this invention are as follows: This stamping press uses a disc feeder, which guides the steel strip to change its angle by setting the angle of the bending rod, avoiding the pressure from the angle change being entirely applied to the frame. Even when the distance from the steel strip on the coil to the guide roller is short, bending and deformation of the steel strip can be avoided. At the same time, the lifting effect of the bending rod prevents the steel strip from falling to the ground. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0023] Reference Figures 1 to 4 The illustrated disc feeder for a stamping press includes a frame 2, a height adjusting rod 4, two bent rods 8, and a circular feed disc 1 rotatably mounted on the frame 2. The frame 2 houses a rotary drive mechanism for rotating the circular feed disc 1. This rotary drive mechanism employs a prior art structure, which will not be described in detail below. A rotatable rotating block 6 is mounted on the vertical rod 2a of the frame 2. The height adjusting rod 4 is slidably mounted on the rotating block 6. A counterweight rod 5 is fixedly mounted on one side of the rotating block 6. A guide roller 3 is fixedly mounted on the bottom end of the height adjusting rod 4. The two bent rods 8 are vertically raised and lowered on the vertical rod 2a via connectors 9. First, a steel strip 10 is laid flat on top of the circular feed disc 1. The free end of the steel strip 10 passes between the two bent rods 8 and around the outer edge of the guide roller 3 before being inserted into the stamping press. The stamping press continuously presses the steel strip 10, and the circular feed disc 1 is continuously unwound via the rotary mechanism, allowing the steel strip to continuously enter the stamping press. Figure 1 It can be seen that each bending rod 8 is inclined upward from right to left. By setting the angle of the bending rod 8, the angle of the steel strip 10 is guided to change, avoiding the pressure of the angle change being entirely applied to the frame 2. Even when the distance from the steel strip to the guide roller is short, bending deformation of the steel strip can be avoided. At the same time, the lifting effect of the bending rod 8 can prevent the steel strip 10 from falling to the ground.

[0024] The two curved rods 8 are staggered, with the upper curved rod 8 being closer to the guide roller 3 than the lower curved rod 8. This staggered arrangement ensures that both curved rods 8 can contact the steel belt 10, avoiding contact only between the upper or lower curved rods 8. This allows for better support of the curved rods 8 and smoother movement when changing direction.

[0025] The connector 9 includes a collar 9a, an extension shaft 9b, and an angle adjustment mechanism 9c. The collar 9a is fitted onto the outer edge of the vertical rod 2a, and a screw is engaged on the outer edge of the collar 9a, with the end of the screw abutting against the vertical rod 2a. One end of the extension shaft 9b is fixedly connected to the collar 9a, and the other end of the extension shaft 9b is fixedly connected to the angle adjustment mechanism 9c. The bent rod 8 is fixedly mounted on the rotating plate 9c2 of the angle adjustment mechanism 9c. The collar 9a allows the angle of the bent rod 8 to be adjusted along the circumference of the vertical rod 2a, and the angle adjustment mechanism 9c allows the vertical angle of the bent rod 8 to be adjusted, ensuring that the angle can be adjusted according to the different widths of the steel strip 10.

[0026] The angle adjustment mechanism 9c includes a bolt 9c1, a support plate 9c3, and two annular rubber pads 9c4. The support plate 9c3 is fixedly mounted on the extension shaft 9b. Two rotating plates 9c2 are rotatably connected to the support plate 9c3 via the bolt 9c1. The two rotating plates 9c2 are clamped on both sides of the support plate 9c3. Annular rubber pads 9c4 are provided on the side of the two rotating plates 9c2 that are in contact with the support plate 9c3. The rotating plates 9c2 rotate on the support plate 9c3, and the bolt 9c1 presses the rotating plates 9c2 against the support plate 9c3, thus fixing the adjusted angle. Furthermore, the addition of annular rubber pads 9c4 increases the friction between the rotating plates 9c2 and the support plate 9c3, improving stability.

[0027] Two stop bars 2b are fixedly installed on the frame 2, and a height adjustment rod 4 is located between the two stop bars 2b. A pressure sensor 11 is fixedly installed on the frame 2. When the height adjustment rod 4 contacts the right stop bar 2b, the outer edge of the height adjustment rod 4 is pressed against the sensing end of the pressure sensor 11. Before the steel strip 10 is taut from the roll to the guide roller, the height adjustment rod 4 is in contact with the left stop bar 2b. When the steel strip 10 is pulled taut, it pulls the guide roller 3 downward, causing the height adjustment rod 4 to come into contact with the left stop bar 2b, and at the same time, the height adjustment rod 4 is pressed against the pressure sensor 11. The pressure sensor 11 transmits an electrical signal to the controller, which controls the circular feed pan 1 to rotate rapidly by one-third of a turn. The steel strip 10 is quickly released from the roll, allowing the guide roller 3 to be lifted upward again by the counterweight rod 5.

[0028] The rotating block 6 has a through hole in the middle for the height adjustment rod 4 to slide. A limit block 7 is clamped on the outer edge of the height adjustment rod 4, and the bottom of the limit block 7 is in contact with the top of the rotating block 6. By adjusting the position of the limit block 7 relative to the height adjustment rod 4, the height of the guide roller 3 is changed, thereby changing the support position of the guide roller 3 on the steel strip 10.

[0029] A counterweight block is fixedly installed at the end of the counterweight rod 5. Only through the action of the counterweight block can the guide roller 3 be tilted up.

[0030] A connecting ring is detachably mounted on the side of the guide roller 3, and a hook 12 extending towards the guide roller 3 is fixedly provided on the connecting ring. By providing the hook 12, the steel strip 10 can be placed on the guide roller 3. When the steel strip 10 malfunctions and needs to be removed, the connecting ring can be removed, and the hook 12 can be removed together.

[0031] This stamping press uses a disc feeder. By adjusting the angle of the bending rod 8, the steel strip 10 is guided to change its angle, preventing all the pressure from being applied to the frame 2. Even when the distance from the steel strip to the guide roller is short, bending and deformation of the steel strip can be avoided. At the same time, the lifting effect of the bending rod 8 prevents the steel strip 10 from falling to the ground.

[0032] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
