Description

Technical Field

[0001] The present application relates to the technical field of clamp forming machines, and in particular to a clamp forming machine with an automatic material return structure. Background Art

[0002] A clamp is a component that uses one material to hold or clamp another material. It is a fastener and has a wide range of applications in industry. A clamp forming machine is required during the production and processing of the clamp.

[0003] During processing, the existing clamp forming machine first straightens and transmits the plate, then uses a stamping mechanism to punch ear holes in advance, and then uses a bending machine to bend and shape the ear holes. After shaping, it retreats a certain distance, and then uses a cutting machine to cut the shaped clamp and the unprocessed plate to complete the processing of a clamp. After cutting, the clamp generally falls directly downward into a collection frame. Since the clamp falls freely, it is relatively messy when it falls into the collection frame, and it often needs to be picked up and stacked manually, which not only wastes human resources, but also reduces processing efficiency. Therefore, the present application proposes a clamp forming machine with an automatic material return structure. Utility Model Content

[0004] The purpose of the present application is to solve the problem that after the existing clamp forming machine has processed the clamps, the clamps fall randomly into the collection frame and need to be picked up and stacked again, resulting in low processing efficiency. The present application provides a clamp forming machine with an automatic material return structure.

[0005] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0006] A clamp forming machine with an automatic material-removing structure, comprising:

[0007] The base has a transmission straightening mechanism, a punching and cutting mechanism, and a bending mechanism arranged on its top from left to right;

[0008] A bracket is arranged on the base and located between the punching and cutting mechanism and the bending mechanism, and two conveyor belts are arranged on the bracket, and the input ends of the two conveyor belts are located on one side of the output end of the punching and cutting mechanism;

[0009] A vertical plate is arranged on the base and located at the output ends of the two conveyor belts. Two shaft rods are arranged on one side of the vertical plate. Two limit rods are arranged on one side of the vertical plate and the two limit rods are staggered with the two shaft rods respectively. Limit plates are rotatably sleeved on the two shaft rods, and the short ends of the two limit plates are overlapped with the two limit rods respectively.

[0010] The lifting mechanism is arranged on the base and located between the output ends of the two conveyor belts, and is used for lifting the conveyed workpiece upwards.

[0011] Furthermore, a torsion spring sleeved on the shaft rod is installed between the limit plate and the vertical plate.

[0012] Furthermore, a U-shaped shell is provided on one side of the vertical plate close to the conveyor belt, a through slot is penetrated through the vertical plate, and a sealing plate for sealing the through slot is provided on the vertical plate.

[0013] Furthermore, one end of the sealing plate is hinged to the opposite side of the inner wall of the through groove, and the other end is movably provided with an insertion rod, and the top end of the vertical plate is provided with an insertion hole, and the insertion rod is plugged into and matched with the insertion hole.

[0014] Furthermore, two guide plates are arranged on the bracket, and the two guide plates correspond to the two conveyor belts one by one respectively.

[0015] Furthermore, grooves are provided on opposite sides of the two guide plates, and a plurality of guide wheels are arranged in an array in the grooves.

[0016] Furthermore, the lifting mechanism includes an electric push rod arranged on a base, and a push plate is arranged on the top of the electric push rod.

[0017] Furthermore, an arc-shaped limiting portion is provided on the top of the push plate.

[0018] The beneficial effects of this application are as follows:

[0019] In the present application, two conveyor belts are arranged on the bracket, and the two conveyor belts can support and transmit the cut and truncated clamps. When the clamp is transmitted to the fitting vertical plate, the lifting mechanism lifts the clamp. When the clamp moves upward, it will drive the two limit plates to rotate. When the clamp passes over the limit plate, the two limit plates rotate and reset, thereby supporting the clamp. With the continuous transmission and continuous lifting of the clamp, the clamp can be overlapped and placed on the vertical plate, which is convenient for the staff to take and place, and there is no need to pick up and stack it later, which reduces the process links and improves the processing efficiency.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0027] like Figure 1-Figure 5As shown, a clamp forming machine with an automatic material unloading structure proposed in one embodiment of the present application comprises: a base 1, on the top of which a transmission straightening mechanism 2, a punching and cutting mechanism 3 and a bending mechanism 4 are arranged in sequence from left to right; the transmission straightening mechanism 2 is used to straighten the coiled metal sheet and assist in transmission, the punching and cutting mechanism 3 is used to punch ear holes or cut and cut the straightened sheet, the bending mechanism 4 is used to bend the sheet into a clamp, a bracket 5 is arranged on the base 1 and is located between the punching and cutting mechanism 3 and the bending mechanism 4, and two transmission belts 6 are arranged on the bracket 5. Preferably, one end of the bracket 5 is rotatably provided with a transmission roller, and the other end is rotatably provided with a transmission roller. There are two driven rollers, one end of the two conveyor belts 6 is driven and sleeved on the conduction roller, and the other end is respectively driven and wound on the two driven rollers. The driving roller rotates under the drive of the driving motor, thereby driving the two conveyor belts 6 to transmit. The input ends of the two conveyor belts 6 are located on the output end side of the punching and cutting mechanism 3; the vertical plate 7 is arranged on the base 1 and is located at the output end of the two conveyor belts 6. Two shaft rods 8 are arranged on one side of the vertical plate 7. Two limit rods 9 are arranged on one side of the vertical plate 7. The two limit rods 9 are staggered with the two shaft rods 8 respectively. The two shaft rods 8 are both rotatably sleeved with limit plates 10. The short ends of the two limit plates 10 are respectively overlapped with the two limit rods 9;The lifting mechanism 19 is arranged on the base 1 and is located between the output ends of the two conveyor belts 6. It is used to lift the transmitted workpiece upward. When processing the hoop, the transmission straightening mechanism 2 straightens and transmits the plate. When the plate is transmitted through the punching and cutting mechanism 3, the ear holes are punched first. After the ear holes of the plate are punched, it is transported again and transported to the bending mechanism 4. The bending mechanism 4 bends the plate to form it into a hoop. After the plate is formed into the hoop, the plate is returned and transported a certain distance so that the formed hoop overlaps the two conveyor belts 6. The punching and cutting mechanism 3 cuts the plate again to separate the processed hoop from the plate. The two conveyor belts 6 are transmitted synchronously, so as to transmit the hoop to overlap with the vertical plate 7. At this time, the lifting mechanism 19 works, and its lifting hoop moves upward. Since the limit plate 10 is rotatably sleeved on the shaft 8, when the lifting mechanism 19 drives the hoop to rise, the ear plates at both ends of the hoop will respectively contact the two limit plates 10, thereby The limiting plate 10 is driven to rotate around the shaft 8 as the center of the circle. At this time, the hoop can continue to move upward. When the hoop passes over the limiting plate 10, the limiting plate 10 will rotate and reset under the action of the center of gravity, so that it maintains a horizontal state and the short end of the limiting plate 10 overlaps the limiting rod 9. At this time, the lifting mechanism 19 drives the hoop to move downward, and the two ends of the hoop will overlap on the two limiting plates 10, and the lifting mechanism 19 continues to move downward, and it is separated from the hoop, and the hoop is placed on the vertical plate 7. The plate continues to be transported and processed to the hoop. The conveyor belt 6 transmits the hoop, and the lifting mechanism 19 repeats the lifting or resetting, so that the hoop is lifted upward in turn, so that the hoop is stacked and placed on the vertical plate 7. When the hoop is stacked to a certain number, the staff will remove it. The overall structure of the device can stack the processed hoop together, which is not only neatly stacked, but also convenient for the staff to take and put, thereby improving practicality. ;

[0028] like Figure 3 As shown, in some embodiments, a torsion spring 11 sleeved on the shaft 8 is installed between the limit plate 10 and the vertical plate 7. Through the torsion spring 11, when the clamp resists the limit plate 10 and rotates, the limit plate 10 will twist and compress the torsion spring 11. When the clamp passes over the limit plate 10, under the torsion force of the torsion spring 11, the limit plate 10 is reset more smoothly, thereby supporting the placement of the clamp, thereby improving practicality.

[0029] like Figure 1 and Figure 2As shown, in some embodiments, a U-shaped shell 12 is provided on one side of the vertical plate 7 close to the conveyor belt 6. Through the U-shaped shell 12, the U-shaped shell 12 and the vertical plate 7 form a limit frame with upper and lower ends connected to each other, so as to limit and prevent the overlapping clamp from tipping over. A through groove is opened through the vertical plate 7, and a sealing plate 13 for blocking the through groove is provided on the vertical plate 7. Through the opened through groove and the sealing plate 13 for blocking the through groove, when the clamp is overlapped to a certain height, the sealing plate 13 can be opened to take the clamp, thereby improving the convenience of taking and placing.

[0030] like Figure 4 As shown, in some embodiments, one end of the sealing plate 13 is hinged to the opposite side of the inner wall of the groove, and the other end is movably inserted with an insertion rod 14. A hole 15 is opened at the top of the vertical plate 7, and the insertion rod 14 is plugged into the hole 15. The sealing plate 13 is rotated around the hinge point to an upright state, and the sealing plate 13 blocks the groove, and then the insertion rod 14 is movably inserted into the hole 15, so as to achieve the effect of fixing the sealing plate 13. When the clamp needs to be removed, the insertion rod 14 is pulled upward to disengage the insertion rod 14 from the hole 15, so that the fixing of the sealing plate 13 can be released. The fixing or releasing method is relatively simple and convenient.

[0031] like Figure 5 As shown, in some embodiments, two guide plates 16 are provided on the bracket 5, and the two guide plates 16 correspond to the two conveyor belts 6 one by one. Preferably, the guide plate 16 has an oblique portion and a straight portion connected to each other. The two guide plates 16 are provided to guide the transmission of the clamp to avoid the displacement of the clamp during transmission, so that the two ear plates of the clamp can be effectively aligned with the two limit plates 10, so that the two limit plates 10 can support and limit the clamp.

[0032] like Figure 5 As shown, in some embodiments, grooves are opened on opposite sides of the two guide plates 16, and a plurality of guide wheels 17 are arranged in an array in the grooves. The opened grooves and the guide wheels 17 arranged in the grooves are used to reduce the contact friction resistance between the clamp ear plate and the guide plate 16, so that the clamp can be transmitted more smoothly.

[0033] like Figure 2 and Figure 3 As shown, in some embodiments, the lifting mechanism 19 includes an electric push rod 1901 arranged on the base 1, and a push plate 1902 is arranged on the top of the electric push rod 1901. When the electric push rod 1901 does work, its piston end drives the push plate 1902 to move, so that the push plate 1902 overlaps with the clamp and drives the clamp to lift.

[0034] like Figure 2 and Figure 3As shown, in some embodiments, an arc-shaped limiting portion 18 is provided on the top of the push plate 1902. Preferably, the arc-shaped limiting portion 18 is matched with the inner wall of the clamp. By setting the arc-shaped limiting portion 18 and utilizing the matching of the arcs of the two, the clamp can be limited when the clamp is pushed to move upward, thereby avoiding the clamp from being offset during the jacking process, thereby improving practicality.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
