Description

Technical Field

[0001] The present application relates to the field of stamping processing technology, and in particular to an automatic loading and unloading system for columnar stamping parts. Background Art

[0002] Stamping is a common part processing method. When processing cylindrical stamping parts, a receiving slot is typically created on the workbench directly opposite the punch to accommodate the part. Because the punch of a stamping machine is located in the center of the machine and requires sufficient space for movement when raising and lowering it, installing a fixed loading device within the press workbench would interfere with the stamping operation.

[0003] There are two existing methods for loading stamped parts: manual loading and robotic loading. Both methods require a hand or robotic arm to reach under the punch to accurately place the workpiece into the receiving slot, then retract the hand or robotic arm after the workpiece is placed. This requires precise timing, allowing loading to occur during the moment the punch is raised. Failure to do so could result in equipment damage or personal injury. Summary of the Invention

[0004] In order to solve the above problems, the loading of stamping parts is not affected by the lifting of the punch, and the safety of the stamping machine is improved. The present application provides an automatic loading and unloading system for columnar stamping parts.

[0005] The present application provides an automatic loading and unloading system for cylindrical stamping parts, which adopts the following technical solutions:

[0006] An automatic loading and unloading system for columnar stamping parts, comprising:

[0007] A stamping table, wherein a mounting hole is formed on the stamping table, the mounting hole is arranged opposite to the punch of the stamping machine, a feeding channel is provided inside the stamping table and is connected to the mounting hole, the entrance of the feeding channel is provided on the side wall of the stamping table, and a transmission mechanism is provided in the feeding channel, and the transmission mechanism is used to transport the workpiece along the feeding channel into the mounting hole;

[0008] The pressure-bearing shaft is inserted into the mounting hole and is used to connect to the punching machine. The end face of the pressure-bearing shaft and the wall of the mounting hole are combined to form a receiving groove, and the receiving groove is used to place the workpiece during punching.

[0009] By adopting the above technical solution, a feed channel is opened inside the punching table, and the entrance of the feed channel is opened on the side wall of the punching table. The feed channel connects the receiving tank to the outside in a horizontal direction. During stamping, the workpiece is transported from the feed channel entrance to the receiving tank through the transmission mechanism, which can completely avoid the feeding channel and the lifting path of the punch, forming an independent feeding line. This eliminates the need to rush to load the material during the lifting of the punch, avoids personal injury or equipment damage caused by improper loading, and improves the safety of the punch feeding operation.

[0010] Furthermore, the transmission mechanism includes a feeding plate and a power device, the feeding plate is slidably connected to the feeding channel, and the power device is used to drive the feeding plate to slide.

[0011] By adopting the above technical solution, the feed plate is slidably connected to the material conveying channel and a power device is provided to drive the feed plate to slide, so that the feed plate can automatically reciprocate for loading and unloading, thereby improving production efficiency.

[0012] Furthermore, the feeding plate is L-shaped, and the opening of the feeding plate faces the inlet of the feeding channel.

[0013] By adopting the above technical solution, the feeding plate is set to be L-shaped. When loading, it can block the workpiece in the forward direction, so that the cylindrical workpiece can remain in a stable position, and avoid the workpiece rolling and changing direction to affect the stamping; and the opening is facing the entrance of the feeding channel, which is convenient for loading on the one hand and for storing the workpiece after stamping on the other hand.

[0014] Furthermore, the feeding plate includes a supporting plate and a baffle, the supporting plate is vertically fixedly connected to the baffle, a sliding rod is rotatably connected to the feeding plate, the sliding rod is located at the connection between the supporting plate and the baffle, and sliding grooves for the sliding rod to slide are opened on both sides of the feeding channel.

[0015] By adopting the above technical solution, the slide bar slides along the slide groove to drive the feed plate, and the feed plate is rotatably connected to the slide bar. The rotation of the feed plate can flip the workpiece and change its placement direction. The baffle rotates to the bottom of the workpiece to support it, so that the end face of the cylindrical workpiece faces the punch, facilitating stamping.

[0016] Furthermore, a magnetic block is provided on the end face of the baffle, and an electromagnet is provided on the inner wall of the mounting hole facing the feed channel. The electromagnet attracts the magnetic block to drive the feed plate to rotate and makes the baffle abut against the end face of the pressure shaft.

[0017] By adopting this technical solution, when the feed plate delivers the workpiece to the port on the side of the feed channel near the receiving slot, the magnetic force generated by the electromagnet attracts the magnetic block, driving the feed plate to rotate. The baffle plate abuts the end surface of the pressure-bearing shaft to resist the pressure of the punch during stamping, minimizing damage to the feed plate. During the stamping process, the workpiece never leaves the feed plate. After stamping is completed, the electromagnet is de-energized, and the feed plate returns to deliver the finished workpiece along the same path.

[0018] Furthermore, a torsion spring is provided on the slide rod for rotating and resetting the feeding plate.

[0019] By adopting the above technical solution, the torsion spring can be set to

[0020] Furthermore, it also includes an intermittent conveying mechanism, wherein a plurality of the feed channels are provided around the mounting hole, and the punching table is connected to the punching machine by rotating around the pressure-bearing shaft, and the intermittent conveying mechanism can convey the workpiece to each of the feed channels in turn.

[0021] By adopting the above technical solution, multiple feed channels are arranged around the mounting hole, and the punching table is rotatably connected to the punching machine. The intermittent conveyor mechanism sequentially conveys the workpiece into each feed channel, which can improve loading efficiency and form an assembly line automatic loading. In addition, the rotation of the punching table can also rotate the entrance of the feed channel to different directions, making it convenient to store finished products at a position on the side of the punching machine that is different from the intermittent conveyor mechanism, thereby realizing automatic loading and unloading at the same time.

[0022] Furthermore, the intermittent conveying mechanism includes a track, a limit member, an eccentric wheel and a driving member. The track is arranged at an angle, and the lower end of the track is close to one side of the stamping table. The limit member is used to block the workpiece and the limit member is rotatably connected to the track. The outer peripheral wall of the eccentric wheel abuts against the bottom of the limit member. The rotation of the eccentric wheel drives the limit member to swing back and forth, and the limit member releases a single workpiece in turn. The driving member is used to drive the eccentric wheel to rotate.

[0023] By adopting the above technical solution, the track is tilted and the workpiece is rolled by its own weight; the limit member is abutted against the top of the eccentric wheel, and the eccentric wheel rotates under the action of the driving member, which can drive the limit member to swing back and forth up and down. The limit member releases individual workpieces in turn, and intermittent loading is achieved with a simple structure.

[0024] Furthermore, a reversing assembly is provided at the lower end of the track, and the reversing assembly is used to push the workpiece laterally to enter the feeding channel.

[0025] By adopting the above technical solution, a reversing component is set to push the workpiece sideways to load the material, so that the smaller end face of the columnar workpiece faces the feeding channel, and the workpiece is placed along the length direction of the feeding channel.

[0026] Furthermore, it also includes a vibration plate, which is located at the higher end of the track.

[0027] By adopting the above technical solution and setting a vibrating plate as a material box, the workpieces can be directional screened and arranged in order for loading.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By placing the feed channel inside the punching table and using a transmission mechanism to transport workpieces from the feed channel entrance to the receiving slot, the loading channel and the punch's lifting path are completely avoided, forming an independent loading line. This eliminates the need to rush to load materials during the punch's lifting interval, preventing injuries or equipment damage caused by improper loading timing, and improving the safety of the punching machine's loading operation.

[0030] 2. An L-shaped feed plate is connected by sliding in the feeding channel, and a power device is set to drive the feed plate to slide for loading and unloading; the electromagnet, magnetic block, and torsion spring cooperate to control the on and off of the electromagnet to realize the automatic rotation of the feed plate for loading and resetting for unloading, thereby improving the degree of automation of the equipment.

[0031] 3. By setting up multiple feed channels around the mounting hole and rotating the punching table to connect to the punching machine, each feed channel sequentially passes through the intermittent conveyor mechanism, forming an assembly line-style automatic loading, which improves loading efficiency. In addition, the rotating punching table cooperates with the transmission mechanism, which conveys the finished workpiece outward. The finished workpiece rotates with the punching table, making it easier to store the finished workpiece at a location on the side of the punching machine, different from the intermittent conveyor mechanism, and using the same equipment to achieve automatic loading and unloading at different locations.

[0039] The following is combined with Figure 1-5 Provide a clear and complete description of the technical solution of this application.

[0040] The embodiment of the present application discloses an automatic loading and unloading system for columnar stamping parts.

[0041] Reference Figure 1 、 Figure 2 The automatic loading and unloading system for columnar stamping parts includes a stamping table 1, a pressure shaft 2, an intermittent conveying mechanism 4, a reversing assembly 5 and a vibration plate 6. The stamping table 1 is rotatably connected to the stamping machine 20 with the pressure shaft 2 as the center. A receiving groove 22 is provided at the position of the stamping table 1 facing the punch 21. A plurality of feeding channels 12 are provided inside the stamping table 1 horizontally connecting the outside with the receiving groove 22. The intermittent conveying mechanism 4 cooperates with the reversing assembly 5 to sequentially convey the workpieces 10 screened by the vibration plate 6 to each feeding channel 12, thereby realizing automatic directional loading of columnar stamping parts.

[0042] By placing the feed channel 12 within the punching table 1, the feeding channel and the lifting path of the punch 21 are completely avoided, forming an independent feeding line. This eliminates the need to rush to load materials during the lifting of the punch 21, preventing injuries or equipment damage caused by improper loading, and improving the safety of the punching machine 20 loading operation. The punching table 1 rotates so that each feed channel 12 passes through the intermittent conveyor mechanism 4, achieving line loading and improving loading efficiency.

[0043] Reference Figure 1 、 Figure 2 The punching platform 1 is disc-shaped, with an axially penetrating mounting hole 11 in the center. One end of the pressure shaft 2 is vertically fixed to the punching machine 20, and the other end of the pressure shaft 2 is inserted into the mounting hole 11. The receiving groove 22 is formed by the end surface of the pressure shaft 2 and the wall of the mounting hole 11.

[0044] Reference Figure 2Three feed channels 12 are arranged in an array around the mounting hole 11. In other embodiments, the number of clinker channels may be two, four, five, or other numbers. The entrance of the feed channel 12 is opened on the side wall of the punching table 1. A transmission mechanism 13 is provided inside the feed channel 12. The transmission mechanism 13 can transport the workpiece 10 along the feed channel 12 into the receiving groove 22.

[0045] Reference Figure 3 、 Figure 4 The transmission mechanism 13 includes a feed plate 131 and a power unit 132. The feed plate 131 is slidably connected to the feed channel 12, and the power unit 132 drives the feed plate 131 to slide. In this embodiment, the power unit 132 is a cylinder. In other embodiments, the power unit 132 can also be an electric push rod or other device. The feed plate 131 slides back and forth along the feed channel 12, performing both loading and unloading. This prevents the feed plate 131 from being idle when resetting, thereby improving the utilization efficiency of the equipment.

[0046] Reference Figure 2 、 Figure 3 , a material receiving box 7 can be optionally set on the side of the stamping table 1 away from the intermittent conveying mechanism 4. After loading and stamping, the entrance of the feeding channel 12 rotates from the side of the intermittent conveying mechanism 4 to the side of the material receiving box 7. At this time, the finished workpiece 10 is sent to the mouth of the feeding channel 12 by the feeding plate 131, and falls into the material receiving box 7 due to inertia, so that the same equipment can be used to realize automatic loading and unloading at different positions.

[0047] Reference Figure 3 、 Figure 4 , the feed plate 131 is L-shaped, and the opening is facing the entrance direction of the feed channel 12. The feed plate 131 includes a support plate 1311 and a baffle 1312. In this embodiment, the support plate 1311 and the baffle 1312 are vertically fixedly connected in an integrally formed manner. In other embodiments, welding or mortise and tenon joints can also be selected. The feed plate 131 is set to be L-shaped. When loading, the baffle 1312 can block the workpiece 10 in the forward direction, so that the cylindrical workpiece 10 remains in a stable position, and prevents the workpiece 10 from rolling and changing its direction and affecting the stamping; and the opening is facing the entrance direction of the feed channel 12, which is convenient for loading on the one hand and for the workpiece 10 to slide outward when unloading on the other hand. A through hole is provided at the intersection of the support plate 1311 and the baffle 1312, and a slide rod 133 is passed through the through hole. The feed plate 131 is rotatably connected to the slide rod 133, and the inner walls on both sides of the feed channel 12 are provided with a slide groove 121 for the slide rod 133 to slide.

[0048] Reference Figure 2 、 Figure 3When loading, placing the workpiece 10 upside down on the feeding plate 131 can lower the center of gravity of the cylindrical workpiece 10. When the workpiece 10 reaches the receiving groove 22, the feeding plate 131 is rotated so that the stamped surface of the workpiece 10 faces the punch 21. Before and after stamping, the end face of the workpiece 10 always remains in contact with the baffle 1312 of the feeding plate 131, so that the workpiece 10 remains stable during transportation.

[0049] Reference Figure 4 A magnet 1313 is installed on the end face of baffle 1312, and an electromagnet 3 is installed on the inner wall of mounting hole 11, facing feed channel 12. Electromagnet 3 engages magnet 1313 to drive feed plate 131 to rotate, bringing baffle 1312 into contact with the end face of pressure-bearing shaft 2. To ensure automatic return of feed plate 131 after stamping, a torsion spring 134 is installed between slide bar 133 and feed plate 131. Electromagnet 3, magnet 1313, and torsion spring 134 work together, and a numerical control system is used to control the on and off of electromagnet 3, enabling automatic rotation of feed plate 131 for loading and resetting for unloading, thereby improving the automation level of the equipment.

[0050] Reference Figure 1 、 Figure 5 The intermittent conveying mechanism 4 includes a track 41, a limiting member 42, an eccentric wheel 43 and a driving member 44. The track 41 is arranged at an angle, and the lower end of the track 41 is close to the side of the punching table 1. There is no need to set a power source, and the workpiece 10 can be rolled down by its own weight to load the material. The limiting member 42 is rotatably connected to the side wall of the track 41. The limiting member 42 is U-shaped and includes two parts, a first stop needle 421 and a second stop needle 422, which are arranged in parallel. The first stop needle 421 is located below the track 41, and the second stop needle 422 is located above the track 41. The outer peripheral wall of the eccentric wheel 43 abuts the bottom of the first stop needle 421. A strip-shaped clearance groove 411 is opened on the bottom wall of the track 41. The first stop needle 421 is inserted into the clearance groove 411 from bottom to top. The second stop needle 422 is arranged opposite to the first stop needle 421 and is offset to form a distance of a workpiece 10, thereby blocking and limiting the workpiece 10 in the track 41. The driving member 44 drives the eccentric wheel 43 to rotate, driving the limit member 42 to swing back and forth, and the first and second ejector pins rise and fall synchronously, sequentially and intermittently releasing individual workpieces 10. In this embodiment, the driving member 44 is preferably a motor, and the rotating shaft of the eccentric wheel 43 is coaxially fixedly connected to the output shaft of the motor.

[0051] Reference Figure 1 A reversing assembly 5 is also provided at the lower end of the track 41. This assembly reciprocates to push the workpiece 10 laterally into the feed channel 12. In this embodiment, the reversing assembly 5 uses a cylinder-driven push plate to reverse the direction of the workpiece 10. A vibrating plate 6 is also provided at the higher end of the track 41. This vibrating plate 6 serves as a material bin, providing directional screening for the workpieces 10, ensuring that they are arranged in an orderly manner for loading.

[0052] The implementation principle of the automatic loading and unloading system of cylindrical stamping parts in the embodiment of the present application is as follows: the vibrating plate 6 transports the cylindrical workpiece 10 to the track 41 in an orderly manner after screening, and the workpiece 10 rolls along the track 41, and the limiter 42 intermittently releases the workpiece 10 in one direction; when the mouth of the feeding channel 12 passes the bottom end of the track 41, the reversing assembly 5 pushes the workpiece 10 laterally into the feeding channel 12; the cylinder contracts to drive the feeding plate 131 to slide, and the feeding plate 131 approaches the accommodating slot 22, and the electromagnet 3 is energized to attract the magnetic block 1313, driving the feeding plate 131 to rotate and load the material. During the loading process, the stamping table 1 continues to rotate. After the stamping is completed, the electromagnet 3 is de-energized, and the torsion spring 134 causes the feeding plate 131 to rotate and reset. The cylinder extends to push the feeding plate 131 outward, and when the feeding plate 131 moves to the mouth of the feeding channel 12, the feeding channel 12 passes through the receiving box 7, and the workpiece 10 falls into the receiving box 7 due to inertia.

[0053] The above are all preferred embodiments of the present application. Obviously, the embodiments described above are only preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made by ordinary technicians in this field based on the structure, shape, and principle of the present application without making any creative work should be covered within the scope of protection of the present application.
