Description

Technical Field

[0001] The utility model relates to the technical field of automobile stamping dies, in particular to a pad for an automobile stamping die. Background Art

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the desired parts.

[0003] After searching, announcement number CN218460651 U discloses a pad for an automobile stamping die, including a support plate, a clamping plate symmetrically screwed on the outer side of a bidirectional screw rod, and one end of any bidirectional screw rod passes through the support plate and is sleeved with a limit gear, a mounting seat is fixedly installed on the rear surface of the support plate, an electric telescopic rod is fixedly installed on the rear surface of the mounting seat, and the output end of the electric telescopic rod is fixedly connected to a fixing block engaged with the limit gear. In fact, the practical new type starts the servo motor to drive the bidirectional lead screw connected to its output shaft to rotate, so that the two guide slide blocks on the outside move in relative or opposite directions, thereby facilitating the control of the spacing between the two clamping plates and facilitating the fixing of the mold. At the same time, a limiting gear is installed on the outside of the bidirectional lead screw, and the electric telescopic rod is started to drive the clamping block connected to its output end to clamp into the tooth gap of the limiting gear, thereby avoiding the phenomenon of wire withdrawal due to the self-rotation of the bidirectional lead screw and improving the firmness of the installed mold; its defect is that when the pad is used to limit and fix the stamping mold, it is limited and fixed by two groups of clamping plates. When it is necessary to fix the special-shaped mold, the clamping plate cannot be used to limit and clamp it steadily, resulting in the displacement of the mold, thereby affecting the stamping effect. Therefore, it is particularly important to improve the existing pad and design a new type of automobile stamping mold pad to solve the above-mentioned technical defects and improve the practicality of the overall pad. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0023] A car stamping die pad includes a pad body 1, the top of the pad body 1 is slidably connected with two groups of clamping parts 2, the ends of the two groups of clamping parts 2 close to each other are rotatably connected with multiple groups of rotating parts 3, the ends of the multiple groups of rotating parts 3 close to each other are rotatably connected with two groups of limit parts 4, the ends of the multiple groups of limit parts 4 close to each other are rotatably connected with a fitting block 5, the inside of the pad body 1 is rotatably connected with two groups of positive and negative screw rods 6, the clamping parts 2 extend to the inside of the pad body 1 and are fixedly connected with a moving block 7, and the clamping parts 2 are connected to the positive and negative screw rods 6 through the moving block 7, and multiple groups of guide holes 8 are provided on the top of the pad body 1 and on both sides away from the two groups of clamping parts 2.

[0024] Furthermore, a plurality of anti-slip strips are provided at one end of the bonding block 5 away from the limiting member 4. The anti-slip strips are rubber anti-slip strips, and the plurality of anti-slip strips are distributed at equal intervals on the outside of the bonding block 5. When the bonding block 5 contacts the stamping die, the anti-slip strips can increase the friction between the bonding block 5 and the stamping die, thereby preventing the bonding block 5 from shifting and affecting the limiting clamping of the stamping die.

[0025] Among them, the moving block 7 is internally rotatably connected with a threaded barrel 9, and a threaded groove is opened inside the threaded barrel 9. The internal structure size of the threaded groove is designed to correspond to the external structure size of the forward and reverse screw rods 6. The threaded barrel 9 is connected to the forward and reverse screw rods 6 through the threaded groove, and the threaded groove is threadedly connected to the forward and reverse screw rods 6, so that the threaded barrel 9 can be threadedly connected to the forward and reverse screw rods 6. When the forward and reverse screw rods 6 rotate, the threaded barrel 9 can be driven to move through the threaded groove, thereby allowing the moving block 7 to move.

[0026] Secondly, one end of the forward and reverse screw rod 6 away from the moving block 7 is fixedly connected with a driving wheel 10, and the two sets of driving wheels 10 are connected by a driving belt 11. The forward and reverse screw rod 6 extends to the outside of the pad body 1 and is fixedly connected to a limited position gear 12, and the driving belt 11 is connected to the two sets of driving wheels 10 so that the two sets of driving wheels 10 can be connected. The driving belt 11 and the driving wheel 10 are meshed and connected. The forward and reverse screw rod 6 is rotated to drive the driving wheel 10 to rotate, so that the driving belt 11 is displaced, so that the other set of driving wheels 10 can rotate, thereby driving the two sets of The forward and reverse screw rods 6 rotate, so that the threaded tube 9 can be displaced, driving the moving block 7 to be displaced, so that the two groups of clamping parts 2 can be displaced, and the stamping die is limited and clamped. When the clamping part 2 contacts the stamping die, the bonding block 5 first contacts the stamping die and rotates itself. At the same time, the limiting part 4 and the rotating part 3 rotate together, so that the bonding block 5 can fit the special-shaped outer surface of the stamping die and limit and clamp it, so as to prevent the special-shaped die from being unable to be steadily limited and clamped when it needs to be fixed, resulting in the die being offset, thereby affecting the stamping effect.

[0027] Furthermore, a clamping piece 13 is provided on the outer side of the limit gear 12, and a support block is provided on the outer side of the pad body 1 and at one end close to the limit member 4. The support block is connected to the clamping piece 13 through a compression spring. The clamping piece 13 is displaced and the connection between it and the limit gear 12 is disconnected, so that the forward and reverse screw rods 6 can rotate. When the moving block 7 is displaced to the specified position, the clamping piece 13 is released, and the clamping piece 13 is displaced by the compression spring, so that the clamping piece 13 can be connected to the limit gear 12 for limiting connection, and the forward and reverse screw rods 6 are limited for limiting connection, so as to prevent the moving block 7 from being offset when it is displaced to the specified position, thereby affecting the limiting clamping of the stamping die.

[0028] Furthermore, the guide hole 8 is rotatably connected with a ball 14, and multiple groups of silicone blocks are arranged on the outside of the ball 14. The multiple groups of silicone blocks are evenly spaced outside the ball 14. The ball 14 is installed inside the guide hole 8 to avoid friction between the guide column of the upper mold and the pad body 1, thereby reducing wear and noise pollution.

[0029] Furthermore, the guide hole 8 extends to the interior of the pad body 1 to form a sound-absorbing groove 15, and a plurality of sound-absorbing pits are formed inside the sound-absorbing groove 15. Sound-absorbing cotton is provided inside the guide hole 8 and the sound-absorbing groove 15. When noise is generated by the stamping die and the pad body 1, the noise is introduced into the interior of the sound-absorbing groove 15 through the guide hole 8, and the sound is transmitted from the high-temperature air to the low-temperature air. The sound-absorbing pit is set in combination with the sound-absorbing cotton to enhance the sound-absorbing effect and reduce the impact on the external environment.

[0030] In this embodiment, the implementation scenario is specifically as follows: during actual use, the displacement clamping part 13 is disconnected from the limit gear 12, so that the forward and reverse screw rods 6 can rotate, and the rotation of the forward and reverse screw rods 6 drives the driving wheel 10 to rotate, so that the driving belt 11 is displaced, so that the other set of driving wheels 10 can rotate, thereby enabling the two sets of forward and reverse screw rods 6 to rotate, so that the threaded barrel 9 can be displaced, and the moving block 7 can be displaced, so that the two sets of clamping parts 2 can be displaced, and the stamping die is limitedly clamped. When the clamping part 2 contacts the stamping die, the bonding block 5 first contacts the stamping die to rotate itself, and at the same time, the limit part 4 and the rotating part 3 rotate in coordination, so that the bonding block 5 can fit the irregular outer surface of the stamping die, limit clamp it, and prevent it from being deformed when the irregular shape is needed. When the shaped mold is fixed, it is impossible to limit and clamp it steadily, resulting in the displacement of the mold, thereby affecting the stamping effect. When the moving block 7 is displaced to the specified position, the clamping piece 13 is released, and the clamping piece 13 is driven to displace by the compression spring, so that the clamping piece 13 can be limitedly connected with the limiting gear 12, and the positive and negative screw rods 6 are limitedly connected to prevent the moving block 7 from being deviated when it is displaced to the specified position, resulting in affecting the limiting clamping of the stamping mold. When the stamping mold and the pad body 1 generate noise, the noise is introduced into the interior of the sound-absorbing groove 15 through the guide hole 8, and the sound is transmitted from the high-temperature air to the low-temperature air. The setting of the silencer pit is used in combination with the sound-absorbing cotton to enhance the silencing effect and reduce the impact on the external environment. Compared with the existing mold pads, the utility model can improve the overall practicality of the mold pads through design.
