Description

Technical Field

[0001] This utility model belongs to the field of copper contact finger hot forging technology, specifically relating to an automated hot forging production line for copper contacts. Background Technology

[0002] Copper contacts are core components in power switchgear, usually made of copper or copper alloys. During the manufacturing process, copper contacts are often manufactured using a special hot forging process. Hot forging is a processing method that involves heating a metal billet and applying pressure to cause it to undergo plastic deformation to obtain specific mechanical properties, shapes, and dimensions. Its main process flow includes heating in a medium-frequency heating furnace, blanking by a punch press, and forging by a spiral press.

[0003] However, in actual production, the demand for copper parts is mostly in the form of multiple varieties and small batches. This means that when using an automated hot forging production line for copper contact fingers, it is necessary to frequently switch molds and gripper assemblies to adapt to workpieces of different specifications. This frequent change not only increases the complexity of operation, but may also lead to a decrease in production efficiency and an increase in costs. Utility Model Content

[0004] In view of this, the present invention provides an automated hot forging production line for copper contact fingers. Through the intelligent collaboration of transfer component one and transfer component two, and with the special structural design of the clamping parts on the first and second gripper assemblies, the production line can handle workpieces of different specifications and states by simply changing the corresponding molds without adjusting or changing the fixtures. This significantly reduces operational complexity, reduces labor costs, and greatly improves production efficiency, achieving a high degree of automation and flexible production of the copper contact finger hot forging process.

[0005] To solve the above-mentioned technical problems, this utility model provides an automated hot forging production line for copper contact fingers, including a feeding and heating mechanism and an automated hot forging mechanism placed at its unloading end. The automated hot forging mechanism includes a first transfer component, a first punch press, a screw press, and a second transfer component located at the unloading end of the feeding and heating mechanism. The first transfer component, the first punch press, the screw press, and the second transfer component are arranged sequentially along the material conveying direction. The end of the first transfer component is equipped with a first gripper assembly, and the feeding and heating mechanism, the first punch press, and the screw press are all within the movement range of the first gripper assembly. The end of the second transfer component is equipped with a second gripper assembly, and the screw press is within the movement range of the second gripper assembly. Through the intelligent coordination of the first and second transfer components, combined with the special structural design of the clamping parts on the first and second gripper assemblies, the production line only needs to change the corresponding mold when processing workpieces of different specifications and states, without adjusting or changing the fixtures. This significantly reduces operational complexity, reduces labor costs, and greatly improves production efficiency, achieving a high degree of automation and flexible production in the copper contact finger hot forging process.

[0006] The transfer unit includes Robot 1, which is located at the unloading end of the feeding and heating mechanism. Punch press 1 is located on one side of Robot 1. Screw press is located at the end of Robot 1 away from the feeding and heating mechanism. Robot 1 is equipped with a first gripper assembly at its end, which plays a role in quickly transferring the blank workpiece.

[0007] The first gripper assembly includes a mounting base located at the end of robot No. 1. The other end of the mounting base is provided with a clamping plate 1. The top of the inner cavity of the mounting base is provided with a guide rail. A clamping plate 2 that cooperates with clamping plate 1 is slidably connected in the guide rail. The relative inner surfaces of clamping plate 1 and clamping plate 2 are both arc-shaped. A telescopic cylinder is provided at the lower part of the end of the mounting base near robot No. 1. The telescopic end of the telescopic cylinder is fixedly connected to clamping plate 2, thereby realizing the function of clamping blank workpieces of different specifications.

[0008] The transfer component 2 includes robot 2, which is located at the unloading end of the screw press. Robot 2 has a second gripper assembly at its end, which enables automatic transfer.

[0009] The second gripper assembly includes a double-headed telescopic pneumatic push rod located at the end of robot No. 2. Both ends of the telescopic push rod are equipped with mounting plates, and the lower end of each mounting plate is equipped with a clamping plate three. The clamping plate three has an L-shaped structure, and the short sides of the two clamping plates three are open on their respective inner surfaces, which means that they can clamp workpieces of different specifications.

[0010] The feeding and heating mechanism includes a material platform placed near Robot No. 1. A sorting machine is placed at the feeding end of the material platform. A sorting machine slide rail is provided on one side of the sorting machine. An intermediate frequency heating furnace is placed at the feeding end of the sorting machine. An automatic feeder is placed at the feeding end of the intermediate frequency heating furnace. An elevator is provided on one side of the automatic feeder. A tipping bucket feeder is placed at the loading end of the elevator, which serves the function of feeding, heating and sorting.

[0011] It also includes a cooling and trimming assembly, which is placed near the cooling and cleaning line of robot No. 2. The unloading end of the cooling and cleaning line is equipped with a trimming punch. The unloading end of the screw press and the feeding end of the cooling and cleaning line are both located within the moving trajectory of the second gripper assembly, thus achieving the purpose of hot forging the workpiece.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. Robot No. 1 drives the first gripper assembly to move. During gripping, the telescopic cylinder operates to push the second gripper plate towards the first gripper plate. The workpiece blank is held by the arc-shaped surfaces of the inner ends of the two grippers. Robot No. 2 drives the second gripper assembly to move. During gripping, the double-headed telescopic pneumatic push rod operates to move the two third grippers centripetally. The formed workpiece is held by the open structure of the inner surfaces of the short sides of the two third grippers. The entire process is achieved through the intelligent coordination of transfer component 1 and transfer component 2, combined with the special structural design of the gripping parts on the first and second gripper assemblies. This allows the production line to handle workpieces of different specifications and states by only changing the corresponding molds without adjusting or changing the fixtures. This significantly reduces operational complexity, reduces labor costs, and greatly improves production efficiency, realizing a high degree of automation and flexible production in the copper contact finger hot forging process.

[0014] 2. After the forging process, the workpiece is placed on the track at the inlet of the cooling and cleaning machine. As the track moves, the workpiece is cooled inside the cooling and cleaning machine. When it reaches the outlet, the cooling is complete. The operator will pick it up and put it into the mold on the edge-trimming punch for edge trimming. The trimmed workpiece is placed in the material box, and the scrap is placed in the scrap bin. This process can shorten the workpiece cooling time and improve the edge trimming effect. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides an automated hot forging production line for copper contact fingers, such as... Figure 1-5 As shown: It includes a feeding and heating mechanism and an automated hot forging mechanism placed at its unloading end. The automated hot forging mechanism includes a transfer component one, a punch press one 9, a screw press 10 and a transfer component two located at the unloading end of the feeding and heating mechanism. The transfer component one, punch press one 9, screw press 10 and transfer component two are arranged sequentially along the conveying direction of the material to be produced. The end of the transfer component one is provided with a first gripper assembly. The feeding and heating mechanism, punch press one 9 and screw press 10 are all within the moving range of the first gripper assembly. The end of the transfer component two is provided with a second gripper assembly. The screw press 10 is within the moving range of the second gripper assembly. The blank workpiece is cylindrical, and the formed workpiece after die forging has a ring of flash waste around it.

[0023] The blank workpiece is processed by the feeding and heating mechanism. Then, robot 18 holds the blank workpiece with the first gripper assembly and then pre-processes it through the automated hot forging mechanism. After the die forging is completed, robot 210 uses the second gripper assembly to hold the flash waste of the formed workpiece and then puts it into the next process. The whole process is achieved through the intelligent collaboration of transfer component 1 and transfer component 2, combined with the structural design of the first gripper assembly and the second gripper assembly. This allows the production line to only need to change the corresponding mold when processing workpieces of different specifications and states without adjusting or changing the fixtures. This significantly reduces the complexity of operation, reduces labor costs, and greatly improves production efficiency, realizing a high degree of automation and flexibility in the production of blank workpieces for copper finger hot forging.

[0024] like Figure 2-4As shown, the transfer component includes robot 1 (8), which is located at the unloading end of the feeding and heating mechanism. Punch press 9 is located on one side of robot 1 (8), and screw press 10 is located at the end of robot 1 (8) away from the feeding and heating mechanism. Robot 1 (8) has a first gripper assembly at its end. The first gripper assembly includes a mounting base 81 located at the end of robot 1 (8). The other end of the mounting base 81 has a clamping plate 82. The top of the inner cavity of the mounting base 81 has a guide rail 83. A clamping plate 84 that cooperates with clamping plate 82 is slidably connected inside the guide rail 83. The relative inner surfaces of clamping plate 82 and clamping plate 84 are both arc-shaped. The lower part of the mounting base 81 near robot 1 (8) has a telescopic cylinder 85. The telescopic end of the telescopic cylinder 85 is fixedly connected to clamping plate 84.

[0025] Robot 1 moves the first gripper assembly to the material platform 7. Then, the telescopic cylinder 85 moves the second gripper 84 towards the first gripper 82. The arc-shaped surfaces of the inner ends of the two grippers contact the outer arc surface of the workpiece blank, thereby clamping the workpiece blank. The workpiece blank is then placed on the working platform of the punch press 9 for pre-forging. After the pre-forging is completed, Robot 1 moves the first gripper assembly to clamp the workpiece blank again and place it into the forging mold cavity on the working platform of the screw press 10 for die forging. By utilizing the arc-shaped structure of the inner sides of the first gripper 82 and the second gripper 84 and the flexible adjustment of the second gripper 84, the workpiece blank of different specifications can be clamped.

[0026] like Figure 2-5 As shown, the transfer component 2 includes robot 2 11, which is located at the unloading end of the screw press 10. Robot 2 11 is equipped with a second gripper assembly at its end. The second gripper assembly includes a double-headed telescopic pneumatic push rod 111 located at the end of robot 2 11. Both ends of the telescopic push rod 111 are equipped with mounting plates 112. The lower end of each mounting plate 112 is equipped with a clamping plate 3 113. The clamping plate 3 113 has an L-shaped structure. The short sides of the two clamping plates 3 113 are open on their respective inner surfaces. The opening structure can be a U-shaped structure or an opening structure with arc-shaped upper and lower ends. The two ends of the opening structure are inclined from the inside to the outside, so that the inclined surface can abut against the surface of the formed workpiece, increasing the contact area.

[0027] Robot 2 moves the second gripper assembly to the screw press 10. Then, the double-headed telescopic pneumatic push rod 111 operates, driving the two clamping plates 113 to move towards the center. Since the short sides of the two clamping plates 113 are open on their respective inner surfaces, the flash of the formed workpiece can be located in the open structure during clamping, thus clamping the flash of the formed workpiece and placing it on the conveyor belt at the inlet of the cooling and cleaning machine 13, realizing the rapid transfer of the formed workpiece. The open structure can be used to clamp and transfer formed workpieces of different specifications.

[0028] like Figure 1 As shown, the feeding and heating mechanism includes a material platform 7 placed near robot 1 8. A sorter 5 is placed at the feeding end of the material platform 7. A sorter slide rail 6 is provided on one side of the sorter 5. An intermediate frequency heating furnace 3 is placed at the feeding end of the sorter 5. An automatic feeder 1 is placed at the feeding end of the intermediate frequency heating furnace 3. An elevator 2 is provided on one side of the automatic feeder 1. A tipping feeder 4 is placed at the loading end of the elevator 2. The mechanism also includes a cooling and trimming assembly. The cooling and trimming assembly is placed near the cooling and cleaning line 12 near robot 2 11. A trimming punch 13 is placed at the unloading end of the cooling and cleaning line 12. The unloading end of the screw press 10 and the feeding end of the cooling and cleaning line 12 are both located within the moving trajectory of the second gripper assembly.

[0029] First, the blank workpiece is placed into the elevator 2 via the tipping feeder 4. Then, the elevator 2 sends the blank workpiece to the track of the automatic feeder 1. Under the push of the push rod of the automatic feeder 1, it enters the pipe of the medium-frequency heating furnace 3 for heating. After heating, the blank workpiece will pass through the sorting machine 5. Blank workpieces that do not meet the forging temperature range will enter the corresponding iron box outside through the sorting machine slide rail 6, while blank workpieces that meet the forging temperature range will enter the material platform 7 through the slide rail of the sorting machine 5. Then, robot 1 8 clamps the blank workpiece with the first gripper assembly and places it on the working platform of punch press 9 for pre-forging. After the pre-forging is completed... After the workpiece is completed, Robot 1 (8) uses the first gripper assembly to grip it again and place it into the forging mold cavity on the working platform of the screw press 10 for die forging. After the die forging is completed, Robot 2 (10) uses the second gripper assembly to grip the flash of the formed workpiece and then places it on the track at the entrance of the cooling and cleaning machine 13. As the track moves, the workpiece is cooled in the cooling and cleaning machine 13. When it reaches the exit, the cooling is completed. The operator will pick it up and place it into the mold on the edge-trimming punch press 13 for edge trimming. The trimmed workpiece is placed in the material box, and the scrap is placed in the scrap bin. At this time, the entire automated hot forging production is completed, which greatly improves the efficiency of copper finger hot forging production.

[0030] The working principle of the automated hot forging production line for copper contact fingers provided by this utility model is as follows: First, the blank workpiece is placed into the elevator 2 through the tipping feeder 4. Then, the elevator 2 sends the blank workpiece to the track of the automatic feeder 1. Under the push of the push rod of the automatic feeder 1, it enters the pipeline of the medium-frequency heating furnace 3 for heating. After heating, the blank workpiece will pass through the sorting machine 5. Blank workpieces that do not meet the forging temperature range will enter the corresponding iron box outside through the sorting machine slide rail 6, while blank workpieces that meet the forging temperature range will... The workpiece enters the material platform 7 via the slide of the sorting machine 5. Then, robot 8 moves the first gripper assembly onto the material platform 7. Next, the telescopic cylinder 85 operates, pushing clamping plate 2 84 towards clamping plate 1 82. The curved surfaces of their inner ends clamp the workpiece, which is then placed on the working platform of punch press 9 for pre-forging. After pre-forging, robot 8 moves the first gripper assembly again to clamp the workpiece and place it into the forging die cavity on the working platform of the screw press 10 for die forging. The die forging process is then completed. After completion, Robot 2 (10) moves the second gripper assembly to the screw press (10). Then, the double-headed telescopic pneumatic push rod (111) operates, driving the two clamping plates (113) to move towards the center. The short sides of the two clamping plates (113) are open on their respective inner surfaces, clamping the flash of the formed workpiece. The workpiece is then placed on the conveyor belt at the inlet of the cooling and cleaning machine (13). As the conveyor belt moves, the workpiece is cooled inside the cooling and cleaning machine (13). When it reaches the outlet, the cooling is complete. The operator picks it up and places it into the mold on the trimming punch (13) for trimming. The trimmed workpiece is placed in the material box, and the scrap is placed in the scrap bin. At this point, the entire automated hot forging production is completed. The entire process is achieved through the intelligent collaboration of transfer component 1 and transfer component 2, combined with the structural design of the first and second gripper assemblies. This allows the production line to handle workpieces of different specifications and states by simply changing the corresponding mold without adjusting or changing the fixtures. This significantly reduces operational complexity, reduces labor costs, and greatly improves production efficiency, achieving a high degree of automation and flexible production in the copper contact finger hot forging process.

[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
