Description

Technical Field

[0001] This utility model relates to the field of sprocket stamping technology for preventing material jamming, specifically a sprocket stamping die for preventing material jamming. Background Technology

[0002] Sprocket molds are tools used to shape items. Sprocket molds typically refer to various molds and tools used to obtain the desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, and stretching.

[0003] The existing technology uses sprocket stamping dies, in which the stamped sprocket is removed manually after stamping, and a new sprocket is put in. This not only causes the material to accumulate continuously, resulting in low work efficiency, but also causes workers to become fatigued and have blurred vision during long-term operation. At this time, workers are extremely easy to be injured by the machine.

[0004] Therefore, we propose a sprocket stamping die to prevent material jamming, in order to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a sprocket stamping die to prevent material jamming, so as to solve the problem mentioned in the background art that requires manual removal of stamped sprockets and insertion of new sprockets. This not only causes material to accumulate and reduces work efficiency, but also causes fatigue and eye strain for workers during long-term operation, making them extremely vulnerable to machine injury.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a workbench and an L-shaped rod fixedly mounted on the workbench. The workbench has a first chamber and a second chamber. A feeding conveyor belt is installed on the first chamber, and a discharging conveyor belt is installed on the second chamber. A limit plate is installed on the workbench. A stamping assembly for stamping a sprocket is installed at the lower end of the L-shaped rod. The stamping assembly includes a telescopic cylinder fixedly mounted on the lower end of the L-shaped rod. A pressure plate is fixedly installed at the telescopic end of the telescopic cylinder. An extrusion groove and a circular groove are provided on the pressure plate. A third chamber is provided on the workbench. A telescopic rod is fixedly mounted on the third chamber. A disc is fixedly mounted at the telescopic end of the telescopic rod. A spring is provided between the disc and the telescopic end of the telescopic rod. A base is fixedly mounted on the third chamber.

[0007] Preferably, the lower end of the L-shaped rod is provided with a pushing assembly for pushing the sprocket away. The pushing assembly includes two fixed rods fixedly installed at the lower end of the L-shaped rod. An arc-shaped rod is fixedly installed at the telescopic end of the telescopic cylinder. A rotating shaft is rotatably installed between the two fixed rods. A pushing rod is fixedly installed on the axial side wall of the rotating shaft. A cross plate is fixedly installed at one end of the pushing rod. A torsion spring is provided between the pushing rod and the fixed rod. An inclined groove is provided on the worktable.

[0008] Preferably, the arc-shaped rod is provided with a positioning component for temporarily positioning the sprocket. The positioning component includes a displacement rod fixedly installed on the side wall of the arc-shaped rod, and an arc-shaped block is fixedly installed at the lower end of the displacement rod. An arc-shaped groove is provided on the worktable, and a shock-absorbing component for damping the base is provided on the third chamber.

[0009] Preferably, the shock absorption assembly includes a fourth chamber formed on the base, a support column fixedly installed on the fourth chamber, a shock absorption spring provided between the support column and the fourth chamber, a circular plate fixedly installed on the axial side wall of the base, a semi-circular groove formed on the circular plate, and a waste trough formed on the worktable.

[0010] Preferably, the size of the pressure plate matches the size of the disc.

[0011] Preferably, the dimensions and depth of the inclined groove meet the rotation requirements of the push rod.

[0012] Preferably, the size of the arc-shaped block matches the size of the sprocket.

[0013] Preferably, the arc surface of the arc-shaped rod and the arc surface of the push rod are in contact.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The feeding conveyor belt moves the sprocket onto the disc. At this time, the arc-shaped block temporarily fixes and positions the sprocket. Then, the telescopic cylinder is activated. With the cooperation of the telescopic cylinder, pressure plate, disc, telescopic rod, extrusion groove, and circular groove, the sprocket is stamped. With the cooperation of the telescopic cylinder, disc, spring, arc-shaped rod, push rod, and rotating shaft, the sprocket is pushed onto the discharge conveyor belt. This avoids the phenomenon of material jamming caused by failure to transport the finished product in time after processing, and also avoids the phenomenon of the finished product being easily damaged by the machine when handled manually. Under the action of the arc-shaped rod, push rod, and torsion spring, the push rod leaves the worktable to avoid affecting the processing of the next material.

[0016] 2. The pressure plate exerts tremendous pressure on the base. At this time, the base buffers most of the pressure through the shock-absorbing spring, which increases the service life of the base. The processed waste will flow into the semi-circular groove through the base and finally be cleaned out from the waste trough, which is collected in time and increases the collection and recycling of waste.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figures 1-3The system includes a workbench 1 and an L-shaped rod 11 fixedly mounted on the workbench 1. The workbench 1 has a first chamber 12 and a second chamber 13. A feeding conveyor belt 14 is installed on the first chamber 12, and a discharge conveyor belt 15 is installed on the second chamber 13. A limit plate 16 is installed on the workbench 1. A stamping assembly 2 for stamping the sprocket is installed at the lower end of the L-shaped rod 11. The stamping assembly 2 includes a telescopic cylinder 21 fixedly mounted on the lower end of the L-shaped rod 11. A pressure plate 22 is fixedly mounted on the telescopic end of the telescopic cylinder 21. The pressure plate 22 has an extrusion groove 24 and a circular groove 25. A third chamber 23 is installed on the workbench 1. A telescopic rod 26 is fixedly mounted on the third chamber 23. A disc 27 is fixedly mounted on the telescopic end of the telescopic rod 26. A spring 28 is provided between the disc 27 and the telescopic end of the telescopic rod 26. A base 29 is fixedly mounted on the third chamber 23.

[0025] The lower end of the L-shaped rod 11 is provided with a pushing assembly 3 to push the sprocket away. The pushing assembly 3 includes two fixed rods 31 fixedly installed at the lower end of the L-shaped rod 11. An arc-shaped rod 32 is fixedly installed at the telescopic end of the telescopic cylinder 21. A rotating shaft 33 is rotatably installed between the two fixed rods 31. A pushing rod 34 is fixedly installed on the axial side wall of the rotating shaft 33. A cross plate 35 is fixedly installed at one end of the pushing rod 34. A torsion spring 36 is provided between the pushing rod 34 and the fixed rods 31. An inclined groove 37 is provided on the worktable 1.

[0026] The size of the pressure plate 22 matches the size of the disc 27, and the pressure plate 22 can squeeze the disc 27 downward and move it into the chamber 3 23.

[0027] The dimensions and depth of the inclined groove 37 meet the rotation requirements of the push rod 34. When the arc rod 32 moves downward, it will squeeze the push rod 34, causing one end of the push rod 34 to move away from the worktable 1 through the rotating shaft 33.

[0028] The size of the arc block 43 matches the size of the sprocket, which allows for better temporary limiting of the sprocket.

[0029] The curved surface of the arc rod 32 and the curved surface of the push rod 34 are in contact. When the arc rod 32 moves up and down, it will squeeze the push rod 34.

[0030] In this embodiment: the sprocket is placed on the feeding conveyor belt 14, and then the feeding conveyor belt 14 drives the sprocket to move onto the disc 27. At this time, the arc-shaped block 43 temporarily fixes and positions the sprocket. Then, the telescopic cylinder 21 is activated, causing the telescopic end of the telescopic cylinder 21 to drive the pressure plate 22 to move downward. The downward movement of the pressure plate 22 squeezes the disc 27, causing the disc 27 to move downward through the telescopic rod 26 until it moves below the arc surface of the base 29. At this time, the sprocket is located at the upper end of the base 29, and the cylinder on the base 29 just passes through the sprocket. At this time, the pressure plate 22 continues to press down, and the extrusion groove 24 and the circular groove 25 just match the base 29, thus completing the stamping of the sprocket. Then, the telescopic cylinder 21 is moved upward, and the disc 27 rises to be level with the worktable 1 under the action of the spring 28. The telescopic end of the telescopic cylinder 21 drives the arc rod 32 to move upward. The arc rod 32 squeezes the push rod 34, causing the push rod 34 to drive the horizontal plate 35 to rotate inward through the rotating shaft 33, pushing the stamped sprocket onto the discharge conveyor belt 15. This avoids the phenomenon of material jamming caused by failure to transport the finished product in time after processing, and also avoids the phenomenon of the finished product being easily damaged by the machine when handled manually. Then, the arc rod 32 leaves the push rod 34. At this time, the push rod 34 returns to its original shape under the action of the torsion spring 36, so as not to occupy the worktable 1 and block the processing of the next material.

[0031] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 4 and Figure 5 The arc-shaped rod 32 is provided with a positioning component 4 for temporarily positioning the sprocket. The positioning component 4 includes a displacement rod 41 fixedly installed on the side wall of the arc-shaped rod 32. An arc-shaped block 43 is fixedly installed at the lower end of the displacement rod 41. An arc-shaped groove 42 is provided on the worktable 1. A shock-absorbing component 5 for damping the base 29 is provided on the three chambers 23.

[0032] The shock absorption assembly 5 includes a chamber 4 51 formed on the base 29, a support column 52 fixedly installed on the chamber 4 51, a shock absorption spring 53 provided between the support column 52 and the chamber 4 51, a circular plate 54 fixedly installed on the axial side wall of the base 29, a semi-arc groove 55 formed on the circular plate 54, and a waste trough 56 formed on the worktable 1, the semi-arc groove 55 and the waste trough 56 being connected.

[0033] In this embodiment, the pressure plate 22 exerts tremendous pressure on the base 29. At this time, the base 29 buffers most of the pressure through the shock-absorbing spring 53, which increases the service life of the base 29. The processed waste will flow into the semi-arc groove 55 through the base 29 and finally be cleaned out from the waste trough 56. Timely collection increases the collection and recycling of waste.

[0034] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
