Description

Technical Field

[0001] This utility model relates to the field of linkage-type stamping machine technology, and more specifically, to a feeding device for a linkage-type stamping machine. Background Technology

[0002] The linkage-type stamping main unit is the core part of the stamping equipment. Its working principle is based on the linkage mechanism to transmit power and realize the stamping process of metal or non-metal materials. It is usually powered by an electric motor, and the power is transmitted to the crankshaft through transmission components such as pulleys and gears.

[0003] A search revealed that Chinese patent CN222536164U discloses a linkage-type stamping equipment material handling device. After the workpiece is stamped, the drive component moves the rotating seat, causing the blanking plate to move below the lower template after the upper template moves upward. At this point, the part can simply be blown off. This helps reduce the frequency of high-pressure air gun position adjustment, reduces production errors caused by positional deviation, and improves the stability and reliability of the production line.

[0004] When the above-mentioned stamping equipment is in use, the workpiece is placed on the lower template, and the hydraulic telescopic rod drives the upper template to move. The upper template stamps the workpiece placed on the lower template. However, when the workpiece is heavy, it is necessary to manually lift the workpiece and place it in the designated position of the lower template. This process is not only labor-intensive, but long-term operation can easily lead to back and shoulder strain for workers. There is also a safety hazard of the workpiece slipping. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a connecting rod type stamping host feeding device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a linkage-type stamping main feeding device, comprising a U-shaped plate and a rotating frame, wherein the rotating frame is located inside the U-shaped plate, and hollow shafts are fixedly connected to both the front and rear sides of the rotating frame, and the opposite ends of the two hollow shafts are movably connected to the U-shaped plate through bearings. A rotating assembly is provided on one of the hollow shafts, the rotating assembly comprising a self-locking motor, a gear rod, and a gear sleeve, the self-locking motor being fixedly installed on the rear side of the U-shaped plate, and the output shaft end of the self-locking motor being fixedly connected to the gear rod, the gear rod meshing with the gear sleeve, the gear sleeve being fixedly sleeved on one of the hollow shafts, and multiple placement components being provided inside the rotating frame, one of the placement components comprising a placement plate, two rotating shafts, a vertical plate, a second hydraulic cylinder, a pressing plate, and two counterweights.

[0007] Furthermore, the two opposing ends of the two rotating shafts are fixedly connected to the shelf, and the opposite ends of the two rotating shafts are movably connected to the rotating frame through bearings. The top of the upright plate is fixedly connected to the shelf, and the two ends of the second hydraulic cylinder are fixedly connected to the extrusion plate and the upright plate, respectively.

[0008] Furthermore, the tops of both counterweights are fixedly connected to the placement plate, and the two counterweights are located on both sides of the second hydraulic cylinder.

[0009] Furthermore, the rotating frame is internally equipped with an extrusion assembly, which includes a connecting frame, a third hydraulic cylinder, and a push plate.

[0010] Furthermore, both ends of the connecting frame are fixedly connected to the U-shaped plate, and both ends of the third hydraulic cylinder are fixedly connected to the connecting frame and the push plate, respectively.

[0011] As can be seen, the above technical solution facilitates pushing the workpiece to the top of the lower template.

[0012] Furthermore, a support assembly is provided at the bottom of the U-shaped plate, the support assembly including a base plate and two first hydraulic cylinders.

[0013] Furthermore, the top and bottom ends of the two first hydraulic cylinders are fixedly connected to the U-shaped plate and the base plate, respectively, and the base plate is provided with multiple mounting holes.

[0014] It can be seen that the above technical solution facilitates the adjustment of the workpiece height.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model uses the retraction of the piston rod on the second hydraulic cylinder to drive the extrusion plate to move horizontally, and the extrusion plate and the placement plate to extrude the workpiece. The self-locking motor drives the gear rod to rotate, which in turn drives the rotating frame and the workpiece to rotate. The push plate pushes the workpiece to the top of the lower template. This cycle is repeated, which is simple to operate and effectively reduces the labor intensity of the workers.

[0017] 2. In this utility model, when the rotating frame rotates, the counterweight will naturally droop under the action of gravity. The torque pulls the placement plate to make slight adjustments in the opposite direction around the rotating axis, always keeping the top of the placement plate horizontal and upward, preventing the workpiece from tilting or slipping due to the rotation of the rotating frame, and ensuring the stability of the workpiece posture. The piston rods on the two first hydraulic cylinders extend to drive the U-shaped plate and the workpiece to move upward, making the workpiece and the stamping reference surface of the lower template flush. The height of the workpiece can be adjusted according to the requirements. The structure is simple and easy to use. Attached Figure Description

[0025] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Refer to the instruction manual appendix Figure 1-5This embodiment of a linkage-type stamping host feeding device includes a U-shaped plate 1 and a rotating frame 2, with the rotating frame 2 located inside the U-shaped plate 1. Hollow shafts 3 are fixedly connected to both the front and rear sides of the rotating frame 2, and the opposite ends of the two hollow shafts 3 are movably connected to the U-shaped plate 1 through bearings. A rotating assembly 8 is provided on one of the hollow shafts 3. The rotating assembly 8 includes a self-locking motor 801, a gear rod 802, and a gear sleeve 803. The self-locking motor 801 is fixedly installed on the rear side of the U-shaped plate 1, and the output shaft end of the self-locking motor 801 is fixedly connected to the gear rod 802. The gear rod 802 meshes with the gear sleeve 803, and the gear sleeve 803 is fixedly sleeved on one of the hollow shafts 3. Multiple placement assemblies 4 are provided inside the rotating frame 2. One placement assembly 4 includes a placement plate 401, two rotating shafts 402, a vertical plate 403, a second hydraulic cylinder 404, a pressing plate 405, and two counterweights 406.

[0027] Furthermore, the two rotating shafts 402 are fixedly connected to the shelf 401 at their opposite ends, and are movably connected to the rotating frame 2 via bearings at their opposite ends. The top of the upright plate 403 is fixedly connected to the shelf 401. The two ends of the second hydraulic cylinder 404 are fixedly connected to the pressing plate 405 and the upright plate 403, respectively. The tops of the two counterweights 406 are fixedly connected to the shelf 401, and the two counterweights 406 are located on both sides of the second hydraulic cylinder 404.

[0028] Furthermore, the rotating frame 2 is equipped with an extrusion assembly 5, which includes a connecting frame 501, a third hydraulic cylinder 502, and a push plate 503. Both ends of the connecting frame 501 are fixedly connected to the U-shaped plate 1, and both ends of the third hydraulic cylinder 502 are fixedly connected to the connecting frame 501 and the push plate 503, respectively.

[0029] Furthermore, a support assembly is provided at the bottom of the U-shaped plate 1. The support assembly includes a base plate 6 and two first hydraulic cylinders 7. The top and bottom ends of the two first hydraulic cylinders 7 are fixedly connected to the U-shaped plate 1 and the base plate 6, respectively. Multiple mounting holes are provided on the base plate 6.

[0030] When the rotating frame 2 rotates, the counterweight 406, whose center of gravity is lower than the axis of the rotating shaft 402, forms a stabilizing torque. When the rotating frame 2 drives the placement plate 401 to rotate, the counterweight 406 will naturally droop under the action of gravity. The torque pulls the placement plate 401 to make slight adjustments in the opposite direction around the rotating shaft 402, always keeping the top of the placement plate 401 horizontal and upward, preventing the workpiece from tilting or slipping due to the rotation of the rotating frame 2, and ensuring the stability of the workpiece posture. Four bolts are inserted into the four mounting holes in sequence, and the base plate 6 is fixed with the four bolts, so that the U-shaped plate 1 is located on one side of the linkage-type stamping host. The two first hydraulic cylinders 7 are started simultaneously. The piston rods on the two first hydraulic cylinders 7 extend and drive the U-shaped plate 1 and the workpiece to move upward, so that the workpiece and the stamping reference surface of the lower template are flush. The height of the workpiece can be adjusted according to the requirements. The structure is simple and easy to use.

[0031] The usage method of this embodiment is as follows:

[0032] In operation, the worker places the workpiece on the placement plate 401, then activates the second hydraulic cylinder 404. The piston rod on the second hydraulic cylinder 404 retracts, causing the extrusion plate 405 to move horizontally. The workpiece is then extruded through the extrusion plate 405 and the placement plate 401. The self-locking motor 801 is then activated, causing the gear rod 802 to rotate. Since the gear rod 802 meshes with the gear sleeve 803, which is fixedly mounted on one of the hollow shafts 3, the gear rod 802 can drive the gear sleeve 803 and the two hollow shafts 3 to rotate. This rotation, in turn, causes the rotating frame 2 and the workpiece to rotate. When the workpiece is on one side of the lower template, the piston rod on the second hydraulic cylinder 404 extends, causing the extrusion plate 405 to move away from the workpiece. The third hydraulic cylinder 502 is then activated, causing the piston rod on the third hydraulic cylinder 502 to extend, causing the push plate 503 to move horizontally. The push plate 503 pushes the workpiece to the top of the lower template. This cycle repeats continuously, making the operation simple and effectively reducing the worker's workload.

Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
