DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the device or element indicated or implied to have a specific orientation, to be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the utility model.

[0021] Please refer to Figure 1 、 Figure 2 , the stamping device for processing the electrical connector, the design of the device follows the existing technical specification, and the structure is mainly composed of the upper die 1 and the lower die 2 arranged in the upper and lower directions. In order to ensure the structural stability and durability of the device, the bottom of the lower die 2 is connected to the support plate 3 by a fixed mode. In actual application, the support plate 3 is similar to the workbench in function, and this expression method is convenient to understand, but in essence, the support plate 3 exists as a support structure.

[0022] A die groove 7 is specially designed on the top of the lower die 2 to meet the needs of the stamping operation. It is worth noting that in actual operation, the top of the upper die 1 is usually provided with a corresponding displacement driving mechanism (such as a cylinder or a screw rod, not shown in the figure), which can drive the upper die 1 to perform linear up-down movement, so as to press the material to be processed placed on the top of the lower die 2 into the die groove 7, and complete the stamping process.

[0023] As shown in Figure 2 、 Figure 3 , compared with the current technical device, the device is provided with a limiting groove 8 penetrating through the support plate 3, and the shell 10 is embedded in the limiting groove 8, so as to accurately position the shell 10 by using the limiting groove 8, and ensure the convenience of the shell 10 in the initial installation stage.

[0024] It should be noted that the fixing between the lower die 2 and the support plate 3 is usually by bolt connection, so the device is also designed with corresponding bolt holes on the upper end of the shell 10, so as to realize the positioning and fixing of the shell 10 by using the existing bolt in the equipment.

[0025] Specifically, the upper end of the shell 10 is connected with a plurality of upper and lower axial exhaust pipes 9. These exhaust pipes 9 are arranged in parallel from left to right, which ensures that even if the inner diameter of a single exhaust pipe 9 is small, the gas can be effectively discharged during the stamping process, thereby improving the operation efficiency and covering the gas injection range as widely as possible.

[0026] Meanwhile, a plurality of mounting grooves 6 are provided through the lower die 2, which correspond to the plurality of exhaust pipes 9. Each mounting groove 6 is inserted with an exhaust pipe 9, and the upper end of each mounting groove 6 is communicated with the die groove 7, ensuring the smooth operation of the exhaust pipe 9.

[0027] Therefore, in actual application, through the cooperation of the exhaust pipe 9 and the mounting groove 6, gas can be injected into the die groove 7, so that the finished product embedded in the die groove 7 after completing the stamping process can be smoothly taken out from the die groove 7, which can significantly improve the processing efficiency. In addition, the exhaust pipe 9 with a smaller inner diameter arranged in cooperation can minimize the damage to the shape of the die groove 7, avoiding the deviation of the shape of the finished product after stamping from the expected shape; the existence of a plurality of exhaust pipes 9 also enables the finished product to be subjected to more uniform and multidirectional upward impact force, ensuring that the finished product has sufficient upward movement power.

[0028] Specifically, in order to ensure that the exhaust pipe 9 can smoothly inject gas upward to drive the finished product to move upward, the device is specially designed with an air inlet hole 16 on one side of the shell 10, so as to be connected with an external air pipe, and then the shell 10 is filled with gas through the external air pipe.

[0029] Meanwhile, in order to ensure that the gas flow direction meets the expected setting, the device is firmly connected with a sealing plate 12 at the lower end of the shell 10 to close the lower end of the shell 10.

[0030] It should be noted that, as shown in Figure 1 The positioning mechanism is mainly composed of a top plate, and the lower side of the top plate is cooperated with a spring through a positioning rod, so that the top plate has a vertical upward movement tendency relative to the support plate 3. In this case, combined with the positioning groove opened on the workpiece to be processed and the positioning block provided on the top plate, it can be ensured that the workpiece to be processed can be stably and appropriately placed above the die groove 7. This design aims to prevent displacement of the workpiece to be processed during the stamping operation, thereby causing stamping errors.

[0031] Therefore, in practical applications, in order to ensure that the workpiece can be effectively constrained by the positioning mechanism, prevent it from being offset due to the impact of the gas continuously discharged by the exhaust pipe 9, the following measures are taken by the device.

[0032] Please refer to Figure 4 The device is fixedly connected with a limiting block 11 inside the shell 10, and a limiting groove 8 is formed through the limiting block 11. At the same time, a sealing block 13 is inserted into the limiting groove 8, and the sealing block 13 is located above the air inlet pipe. A displacement mechanism is arranged at the lower end of the sealing block 13, which can drive the sealing block 13 to move up and down linearly. When the sealing block 13 is embedded in the sealing groove, the cooperation between the sealing block 13 and the limiting block 11 will block the gas flow channel inside the shell 10, at this time, the exhaust pipe 9 will stop discharging gas to impact the workpiece. When the sealing block 13 is separated from the sealing groove, the gas can continue to flow upward through the gap between the sealing block 13 and the limiting groove 8, at this time, the exhaust pipe 9 can resume discharging gas to impact the workpiece.

[0033] Further, in order to ensure the stability and durability of the device, the limiting block 11 of the device is designed to have a trapezoidal structure in the vertical direction. Specifically, the width and length of the upper end of the limiting block 11 are smaller than those of the lower end. This design aims to quickly realize the opening and closing function of the gas flow channel when the sealing block 13 moves up and down.

[0034] At the same time, the length and width of the lower end of the limiting block 11 are smaller than the corresponding length and width of the inner wall of the shell 10. This arrangement ensures that by moving the limiting block 11, the device can smoothly realize the opening and closing operation of the gas flow channel.

[0035] In addition, in order to further improve the performance of the device, a sealing gasket 17 made of rubber is added to the outside of the limiting block 11. When the limiting block 11 is inserted into the limiting groove 8, the sealing gasket 17 forms an interference fit with the limiting groove 8, thereby ensuring the sealing performance of the device.

[0036] Specifically, the displacement mechanism is composed of a driven plate 4 located at the lower part of the sealing plate 12, and a plurality of follower rods 5 are fixedly connected to the upper end of the driven plate 4. In order to ensure the stability and reliability of the follower rods 5, a through hole I is provided on the support plate 3 for the follower rods 5, and the follower rods 5 are inserted and penetrate through the through hole I.

[0037] At the same time, the design of the device ensures that the projection of the upper die 1 on the horizontal plane can cover the projection of the follower rod 5 on the horizontal plane. When the upper die 1 and the die groove 7 are at the same horizontal position, the follower rod 5 will move downward synchronously with the lowering of the upper die 1. This design enables the follower rod 5 to move downward synchronously during the process of the upper die 1 pressing the workpiece and embedding it into the die groove 7.

[0038] Therefore, the device is provided with a connecting rod 14 on the upper part of the driven plate 4, and the connecting rod 14 is fixedly connected with the sealing block 13. At this time, only the transmission connection between the driven plate 4 and the connecting rod 14 needs to be ensured, so that the sealing block 13 can be separated from the limiting groove 8 during the downward movement of the driven plate 4 (i.e. the upper die 1), thereby allowing the exhaust pipe 9 to upwardly discharge the gas to impact the workpiece to be processed.

[0039] Further, in order to ensure that the workpiece to be processed has sufficient upward movement stroke length, the upper end surface height of the follower rod 5 is designed to be consistent with the upper end surface height of the lower die 2. Moreover, when the upper die 1 is at the same horizontal position as the die groove 7, the lower end surface of the upper die 1 will be in abutting state with the follower rod 5. This design is intended to ensure that the exhaust pipe 9 can continuously discharge the gas upwardly during the entire embedding process of the upper die 1 into the die groove 7, thereby effectively impacting the workpiece to be processed.

[0040] Specifically, in order to achieve effective transmission connection between the connecting rod 14 and the driven plate 4, the connecting rod 14 is designed in the form of a bolt rod. The bolt head of the connecting rod 14 is arranged below the driven plate 4. Therefore, a through hole II is specially provided on the sealing plate 12 for the screw rod part of the connecting rod 14, and the connecting rod 14 is inserted into the through hole II. This design utilizes the bolt head of the connecting rod 14 to drive the connecting rod 14 and further drive the sealing block 13 to move downwardly synchronously during the downward movement of the driven plate 4.

[0041] Meanwhile, a compression spring 15 is further sleeved outside the screw rod part of the connecting rod 14. The two axial ends of the compression spring 15 are in close abutment with the sealing block 13 and the sealing plate 12, respectively. This configuration ensures that the connecting rod 14 always has a tendency to move upwardly. That is, when the upper half of the die removes the downward pressure applied to the follower rod 5, the sealing block 13 will be automatically reset upwardly under the action of the compression spring 15. At this time, the driven plate 4 and the connecting rod 14 will also move upwardly.

[0042] In actual application, the operation process of the device is as follows:

[0043] Firstly, the workpiece to be processed is placed above the die groove 7, and the stability of the position of the workpiece to be processed is ensured by means of the positioning mechanism. At this time, the sealing block 13 is embedded into the limiting groove 8;

[0044] Subsequently, the displacement driving mechanism is used to drive the upper die 1 to move downwardly. During this movement, when the upper die 1 contacts the workpiece to be processed, it also contacts the follower rod 5 at the same time;

[0045] Then, the upper die 1 continues to move downwardly to apply pressure to the workpiece to be processed, so that the workpiece to be processed is deformed and embedded into the die groove 7. At this time, the follower rod 5 drives the driven plate 4 and the sealing block 13 to move downwardly synchronously, so that the sealing block 13 is separated from the limiting groove 8;

[0046] Then, the single stamping process is declared complete, the upper die 1 will be reset upwards. In this reset process, the sealing block 13 and the limiting block 11 will be separated from each other, at the same time, the exhaust pipe 9 will continue to exhaust gas, impact on the lower end of the workpiece, the workpiece will rise with the upper die 1 rises;

[0047] Finally, with the continuous reset of the upper die 1, the distance between the sealing block 13 and the limiting block 11 will gradually decrease. When the lower end surface height of the upper die 1 exceeds the height of the lower die 2, the sealing block 13 will be embedded in the limiting groove 8 again, at this time, the upward thrust on the workpiece will disappear, and then it will fall into the die groove 7.

[0048] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
