Description

Technical Field

[0001] The utility model relates to the field of stamping dies, in particular to a stamping die for a mobile phone connector. Background Art

[0002] The stamping die for mobile phone connectors is a key link in the manufacturing of mobile phone connectors. It efficiently processes metal sheets into connector parts of specific shapes through the stamping process. This kind of die can not only greatly improve production efficiency, but also ensure product quality and dimensional consistency, reduce costs, and promote environmental protection and resource recycling. Its design and production require high-precision equipment and technical guarantees, and during use, it is also necessary to pay attention to cleaning, lubrication and regular maintenance to ensure the durability and processing accuracy of the die. In short, the stamping die for mobile phone connectors is an important tool to ensure the quality, efficiency and cost-effectiveness of mass production of mobile phone connectors.

[0003] Currently, the stamping process of mobile phone USB terminals mostly adopts continuous processing equipment. However, in actual application, this continuous operation mode brings a significant problem: since the workpiece continues to move during the processing, the sliding friction between the workpiece and the mold is constant. As time goes by, the mold surface is prone to scratches, which not only affects the service life of the mold, but also reduces the accuracy of the stamped workpiece. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a mobile phone connector stamping die to solve the technical problem that there is a certain sliding friction between the workpiece and the die, which is prone to scratches on the die surface as the die is used for a longer time.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stamping die for a mobile phone connector, comprising a lower die, an upper die and a workpiece, auxiliary mechanisms are arranged on both sides of the top of the lower die, the auxiliary mechanisms include two limit plates, side plates are arranged on the upper inner side of the limit plates, a support plate is arranged below between the two limit plates, rollers are installed on the top of the support plate through a support frame, an installation groove is opened on the surface of the limit plate, pressure rods are arranged on both sides of the bottom of the upper die, and a spring sleeve rod is arranged between the support plate and the lower die.

[0006] By adopting the above technical solution, the downward pressure of the upper mold will drive the pressure rod to press the support plate, which enables the support plate to overcome the elastic force of the spring sleeve rod and move downward. At the same time, the roller installed on the support plate will also move downward, thereby canceling the supporting effect on the bottom surface of the workpiece, so that the upper mold can punch the workpiece. When the punching is completed, the pressure rod will rise with the upper mold and cancel the pressure on the support plate. At this time, the elastic force of the spring sleeve rod will cause the support plate and the roller to rebound upward and re-contact the bottom surface of the workpiece. What is important is this contact support method between the workpiece and the roller.

[0007] Furthermore, two spring sleeve rods are provided, and the two spring sleeve rods are arranged in a mirror image along the length center line of the support plate.

[0008] By adopting the above technical solution, the setting of the two spring sleeve rods provides a more stable supporting force, ensuring that the support plate can be evenly stressed during the stamping process and preventing deviation or tilting caused by single-point support.

[0009] Furthermore, a plurality of rollers are provided, and the plurality of rollers are linearly arranged at equal intervals along a width line of the support plate, and the rollers abut against the bottom surface of the workpiece.

[0010] By adopting the above technical solution, the setting of multiple rollers increases the contact area with the bottom surface of the workpiece, making the support more uniform and stable, and effectively preventing the workpiece from shaking or shifting during the stamping process. At the same time, the rollers arranged equidistantly and linearly can ensure that the friction force on the workpiece during movement is evenly distributed, avoiding local wear caused by single-point friction, thereby extending the service life of the workpiece.

[0011] Furthermore, both sides of the support plate penetrate the limiting plate through the mounting grooves, and the pressure rod is opposite to the limiting plate.

[0012] By adopting the above technical solution, the mounting groove penetrates the limiting plate so that the support plate can stably move up and down within a limited range, thereby ensuring the accuracy and controllability of the stamping process.

[0013] Furthermore, the side plate and the limiting plate are in an "L"-shaped structure, which is used to limit the moving position of the workpiece.

[0014] By adopting the above technical solution, the "L"-shaped structure provides a stable limiting space for the workpiece, which can effectively prevent the workpiece from lateral or longitudinal displacement during the stamping process, thereby ensuring the accuracy of stamping and the quality of the workpiece.

[0015] Furthermore, a rubber block is installed at the bottom end of the pressure rod.

[0016] By adopting the above technical solution, the rubber block has good elasticity and buffering performance, which can effectively reduce the impact force of the pressure rod on the support plate and prevent damage caused by direct rigid contact, thereby extending the service life of the mold.

[0017] In summary, the utility model mainly has the following beneficial effects:

[0018] 1. The utility model uses an auxiliary mechanism, and the upper mold presses down to drive the pressure rod to press the support plate, so that the support plate overcomes the elastic force of the spring sleeve rod and moves downward. At the same time, the roller also moves downward, canceling the support for the bottom surface of the workpiece, thereby allowing the upper mold to punch the workpiece. After the punching is completed, the pressure rod cancels the pressure on the support plate, and the elastic force of the spring sleeve rod causes the support plate and the roller to rebound and re-contact the bottom surface of the workpiece. In this process, the contact support between the workpiece and the roller transforms the original sliding friction between the workpiece and the mold into rolling friction between the workpiece and the roller, which significantly reduces the friction, improves the protection of the mold, and prolongs the service life of the mold. At the same time, it also improves the processing accuracy of the workpiece;

[0019] 2. The utility model arranges a rubber block, which has good elasticity and can effectively absorb the impact of the pressure rod on the support plate, reducing the damage caused by rigid collision. At the same time, the buffering performance of the rubber block also plays a key role. It can disperse the impact force and prevent damage to the mold due to direct rigid contact. It not only protects the integrity of the mold, but also significantly extends the service life of the mold, thereby reducing maintenance costs and replacement frequency, and improving production efficiency.

[0028] The following describes an embodiment of the utility model based on its overall structure.

[0029] Embodiment 1:

[0030] Mobile phone connector stamping die, such as Figure 1-Figure 4As shown, it includes a lower mold 1, an upper mold 2 and a workpiece 3. Auxiliary mechanisms 4 are arranged on both sides of the top of the lower mold 1. The auxiliary mechanisms 4 include two limit plates 401. Side plates 404 are arranged on the inner upper side of the limit plates 401. A support plate 406 is arranged below the two limit plates 401. Rollers 405 are installed on the top of the support plates 406 through support frames 407. Mounting grooves 402 are opened on the surfaces of the limit plates 401. Pressing rods 408 are arranged on both sides of the bottom of the upper mold 2. Spring sleeve rods 403 are arranged between the support plates 406 and the lower mold 1. The downward pressure of the upper mold 2 will drive the pressing rods 408 to press the support plates 406, which enables the support plates 406 to overcome the elastic force of the spring sleeve rods 403 and move downward. The roller 405 on the support plate 406 will also move downward, thereby canceling the supporting effect on the bottom surface of the workpiece 3, so that the upper mold 2 can punch the workpiece 3. When the punching is completed, the pressure rod 408 will rise with the upper mold 2 and cancel the pressure on the support plate 406. At this time, the elastic force of the spring sleeve rod 403 will cause the support plate 406 and the roller 405 to rebound upward and re-abut against the bottom surface of the workpiece 3. What is important is that this abutment support method between the workpiece 3 and the roller 405 effectively converts the original sliding friction between the workpiece 3 and the mold into rolling friction between the workpiece 3 and the roller 405. This conversion significantly reduces friction damage and improves the durability of the mold, thereby extending the service life of the mold and ensuring the processing accuracy of the workpiece 3.

[0031] See also Figure 3 , Figure 4 There are two spring sleeve rods 403, and the two spring sleeve rods 403 are arranged in a mirror image along the length center line of the support plate 406. The setting of the two spring sleeve rods 403 provides a more stable supporting force, ensuring that the support plate 406 can be evenly stressed during the stamping process, and preventing deviation or tilt caused by single-point support. At the same time, the mirror image arrangement makes the rebound force of the spring sleeve rod 403 more uniform. When the stamping is completed, the support plate 406 and the roller 405 can be quickly and smoothly pushed back to the initial position to prepare for the next stamping cycle, which not only improves the stability and efficiency of the stamping, but also extends the service life of the mold.

[0032] See also Figure 3 , Figure 4There are multiple rollers 405, and the multiple rollers 405 are arranged in an equidistant linear manner along the width line of the support plate 406. The rollers 405 abut against the bottom surface of the workpiece 3. The arrangement of multiple rollers 405 increases the contact area with the bottom surface of the workpiece 3, making the support more uniform and stable, and effectively preventing the workpiece 3 from shaking or shifting during the stamping process. At the same time, the equidistant linearly arranged rollers 405 can ensure that the friction force exerted on the workpiece 3 during the movement is evenly distributed, avoiding local wear caused by single-point friction, thereby extending the service life of the workpiece. In addition, the abutment method of the rollers 405 and the bottom surface of the workpiece 3 also effectively reduces the friction resistance during the stamping process, thereby improving the stamping efficiency and the workpiece quality.

[0033] See also Figure 3 , Figure 4 Both sides of the support plate 406 penetrate the limit plate 401 through the installation groove 402, and the pressure rod 408 is opposite to the limit plate 401. The installation groove 402 penetrates the limit plate 401 so that the support plate 406 can move up and down stably within a limited range, ensuring the accuracy and controllability of the stamping process. At the same time, the pressure rod 408 is opposite to the limit plate 401, ensuring that when the upper mold 2 is pressed down, the pressure rod 408 can accurately act on the support plate 406, thereby effectively controlling the depth and strength of the stamping, and further improving the stamping accuracy and the quality of the workpiece 3.

[0034] See also Figure 3 , Figure 4 The side plate 404 and the limiting plate 401 are in an "L" shape, which is used to limit the moving position of the workpiece 3. The "L" shape structure provides a stable limiting space for the workpiece 3, which can effectively prevent the workpiece 3 from lateral or longitudinal displacement during the stamping process, thereby ensuring the accuracy of the stamping and the quality of the workpiece. At the same time, this structure can also assist in the precise positioning and stable movement of the workpiece after the workpiece 3 is processed, avoiding the position disorder of the workpiece 3 during the removal or transportation process, and improving the production efficiency and operation convenience.

[0035] Embodiment 2:

[0036] See also Figure 1 , Figure 2 , Figure 3 , Figure 4A rubber block 409 is installed at the bottom end of the pressure rod 408. The rubber block 409 has good elasticity and buffering performance, which can effectively reduce the impact force of the pressure rod 408 on the support plate 406 and prevent damage caused by direct rigid contact, thereby extending the service life of the mold. At the same time, the rubber block 409 can also increase the friction between the pressure rod 408 and the support plate 406, ensuring stable contact between the two during the stamping process, thereby improving the accuracy and stability of the stamping. The installation of the rubber block 409 not only protects the mold, but also improves the reliability and efficiency of the stamping process.

[0037] The implementation principle of the utility model is as follows: during the stamping process of the workpiece 3, the workpiece is placed between the two limit plates 401, and the side plates 404 are used to support the workpiece 3. Through the downward pressing operation of the upper mold 2, the bottom end of the pressing rod 408 is driven to press the support plate 406, and the support plate 406 overcomes the elastic force of the spring sleeve rod 403 to move downward. At the same time, the roller 405 is driven to move downward, canceling the supporting effect of the roller 405 on the bottom surface of the workpiece 3. When the stamping is completed, the pressing rod 408 is driven by the upper mold 2, causing the pressing rod 408 to press against the support plate 406. The pressure rod 408 cancels the pressing operation on the support plate 406, and rebounds upward through the elastic force of the spring sleeve rod 403, which is conducive to making the roller 405 contact with the bottom surface of the workpiece 3 again, and then the workpiece 3 is moved. At this time, due to the contact support between the workpiece 3 and the roller 405, it is conducive to improving the original sliding friction between the workpiece 3 and the mold into rolling friction between the workpiece 3 and the roller 405, avoiding direct sliding friction between the workpiece 3 and the mold during the movement process, thereby improving the protection of the mold, and improving the service life of the mold and the processing accuracy of the workpiece 3;

[0038] During the sliding movement of the workpiece 3 , the limiting plate 401 can be used to limit the workpiece 3 , which is helpful to avoid position deviation of the workpiece 3 during the movement, thereby improving the processing accuracy of the workpiece 3 .

[0039] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.
