Description

Technical Field

[0001] The utility model relates to the technical field of bead pressing dies, and specifically, to a multi-station continuous bead pressing die for automotive chassis parts. Background Art

[0002] Bead pressing refers to a design element in die design to improve stiffness and prevent deformation. Generally, some long strip-shaped protrusions are added to a flat plate or a wall plate to achieve this effect. The main function of bead pressing is to increase the stiffness and stability of the die, prevent the die from deforming or vibrating during the processing, thereby improving the life and processing quality of the die. The punch of an automotive part bead pressing die is usually installed in the upper half of the die, that is, on the fixed template or the slider of the stamping die. During installation, the punch needs to be accurately aligned with the die to avoid damaging the die or affecting the product quality.

[0003] Regarding bead pressing dies, there are many existing technologies, for example:

[0004] Chinese Patent Application No. 202220795641.0 discloses a structure including a lower template and an upper die base. There are four upper inclined wedges between the lower template and the upper die base. One side of the upper inclined wedge is slidably connected with a slider. One side of the slider is provided with a punch. The inside of the slider is provided with a marking component for cooperating with the upper inclined wedge to detect the uniformity of extrusion force. Through the extrusion friction of the upper inclined wedge on the transfer mounting plate, and through the multi-layer marking areas on the surface of the transfer mounting plate, the uniformity of the extrusion friction of the upper inclined wedge on the transfer mounting plate is displayed, thereby reflecting the uniformity of the force when the transfer mounting plate is pushed by the upper inclined wedge, and being able to reflect the flatness of the upper inclined wedge, so as to better adjust the flatness of the upper inclined wedge, make the force exerted by the upper inclined wedge on the slider more uniform, and more intuitively observe the stress state of the transfer mounting plate through the wear state of the multi-layer marking areas.

[0005] However, during the use of existing bead pressing dies, sometimes the punch is installed on the lower pressing slider. After the punch is installed, it is easy to be misaligned with the die. Generally, the punch uses a threaded fixing method and needs to be disassembled and reinstalled. It is impossible to align the installed punch with the die by moving it, resulting in low efficiency. In view of this, we propose a multi-station continuous bead pressing die for automotive chassis parts. Summary of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Beading refers to a design element in mold design to improve stiffness and prevent deformation. Generally, some long strip-shaped protrusions are added to the flat plate or wall plate part to achieve this effect. The main function of beading is to increase the stiffness and stability of the mold, prevent the mold from deforming or vibrating during the processing, thereby improving the service life and processing quality of the mold. The punch of the automotive part beading mold is usually installed in the upper half of the mold, that is, on the fixed template or slider of the stamping die. During installation, the punch needs to be accurately aligned with the die to avoid damaging the mold or affecting the product quality.

[0025] Please refer to Figures 1 - 4 As shown, this embodiment provides a multi-station continuous beading mold for automotive chassis parts, including a lower pressing slider 1. In order to adjust the position of the punch 13 after installation, specifically as follows: A long chute 11 is opened at the bottom of the lower pressing slider 1. A long slider 214 is slidably connected to the inner wall of the long chute 11. A concave plate 22 is fixedly connected to the bottom of the long slider 214. A first threaded rod 21 is threadedly connected to the upper side of the front surface of the concave plate 22. Both ends of the first threaded rod 21 are rotatably connected to side plates 12. The tops of the side plates 12 are fixedly connected to the bottom of the lower pressing slider 1. A rectangular chute 225 is opened at the top of the inner surface of the concave plate 22. A rectangular slider 226 is slidably connected to the inner wall of the rectangular chute 225. An installation block 2 is fixedly connected to the bottom of the rectangular slider 226. A punch 13 is provided at the bottom of the installation block 2. A second threaded rod 221 is threadedly connected inside the installation block 2. The end of the second threaded rod 221 is rotatably connected inside the concave plate 22. The other end of the second threaded rod 221 is fixedly connected to a bevel gear 222. Another bevel gear 222 is meshed with the outer surface of the bevel gear 222. The front surface of the other bevel gear 222 is fixedly connected to the end of a rotating shaft 223. The concave plate 22 moves along the length direction of the first threaded rod 21, and the installation block 2 moves along the length direction of the second threaded rod 221. However, during the use of the existing beading mold, the punch 13 is sometimes installed on the lower pressing slider 1. After the punch 13 is installed, it is easy to be not aligned with the die. The punch 13 generally uses the thread fixing method and needs to be disassembled and reinstalled. It is impossible to align the installed punch 13 with the die by moving it, resulting in low efficiency.

[0026] The improvement of this embodiment lies in:

[0027] First, the first threaded rod 21 rotates to drive the pulley 211 to rotate. Then, the pulley 211 rotates to drive the belt 212 to rotate. Immediately afterwards, the belt 212 rotates to drive another pulley 211 and another first threaded rod 21 to rotate. And the two first threaded rods 21 rotate simultaneously to drive the concave plate 22 to move back and forth. Then, the rotating shaft 223 rotates to drive the two bevel gears 222 to rotate. The rotation of the bevel gears 222 drives the second threaded rod 221 to rotate. The rotation of the second threaded rod 221 drives the mounting block 2 to move left and right, enabling the punch 13 to still move back and forth, left and right even after being installed, improving efficiency and increasing the scope of application.

[0028] To enable the two first threaded rods 21 to rotate simultaneously, a pulley 211 is fixedly connected to the outer surface of the first threaded rod 21 near the end. The outer surface of the pulley 211 is rotatably connected to a belt 212. The inner surface of the belt 212 is rotatably connected to another pulley 211. Another first threaded rod 21 is fixedly connected to the axis of the other pulley 211. A handle 213 is fixedly connected to the right end of the first threaded rod 21. First, the handle 213 rotates to drive the pulley 211 and the first threaded rod 21 to rotate. Then, the pulley 211 rotates to drive the belt 212 to rotate. Immediately afterwards, the belt 212 rotates to drive another pulley 211 to rotate. And the rotation of another pulley 211 drives another first threaded rod 21 to rotate, realizing the simultaneous rotation of the two first threaded rods 21.

[0029] To facilitate the rotation of the rotating shaft 223, the other end of the rotating shaft 223 is rotatably connected inside the concave plate 22. A motor 224 is fixedly connected to the front outer surface of the concave plate 22. The end of the motor 224 extends into the concave plate 22 and is fixedly connected to the end of the rotating shaft 223. The rotation of the motor 224 drives the rotating shaft 223 to rotate, realizing the convenience of the rotation of the rotating shaft 223.

[0030] Secondly, to be able to install punches 13 of different sizes, a T-shaped sliding groove 227 is opened at the bottom of the mounting block 2. A T-shaped slider 32 is slidably connected to the inner wall of the T-shaped sliding groove 227. A fixing plate 3 is fixedly connected to the bottom of the T-shaped slider 32. A groove 31 is opened on the inner surface of the fixing plate 3. A hole groove 228 is opened on the right side of the front surface of the mounting block 2. First, the number of fixing plates 3 is two. The top of one fixing plate 3 is fixed to the bottom of the mounting block 2, and the top of the other fixing plate 3 is fixed to the bottom of the T-shaped slider 32. Then, the T-shaped slider 32 can slide to clamp punches 13 of different sizes.

[0031] Considering that the clamping of the fixed plate 3 is not stable enough, a fixed block 33 is fixedly connected to the outer surface of the upper side of the punch 13, and the fixed block 33 is adapted to the groove 31. The internal thread of the hole groove 228 is connected with a bolt 34, and the end of the bolt 34 is threadedly connected to the inside of the T-shaped slider 32. First, the groove 31 clamps the fixed block 33, and then the fixed plate 3 fixes the punch 13 to achieve stable clamping of the fixed block 33.

[0032] In summary, the working principle of this solution is as follows:

[0033] Manually unscrew the bolt 34, pull the right side of the groove 31 to the right, hold the punch 13 to insert the fixing block 33 into the groove 31, pull the groove 31 to the left, so that the right groove 31 is also tightened by the fixing block 33, and manually tighten the bolt 34. The top of the punch 13 just coincides with the bottom of the mounting block 2, so that the top of the punch 13 can also withstand part of the force during the downward pressing process, so that the fixing block 33 is not easy to break, which is convenient for installation and disassembly, and different sizes of punches 13 can be installed, and the handle 213 is manually turned. The handle 213 is rotated to drive the first threaded rod 21 to rotate, and the pulley 211 is driven to rotate, and then the pulley 211 rotates to rotate the belt 212, and then the belt 212 rotates to drive another pulley 211 to rotate, and at the same time, the other pulley 211 rotates to drive another The first threaded rod 21 rotates, and the concave plate 22 is driven to move forward and backward by the simultaneous rotation of the two first threaded rods 21. When the punch 13 moves forward and backward to the ideal position, the motor 224 is powered on, and the rotation of the motor 224 drives the rotating shaft 223 to rotate, and the rotation of the rotating shaft 223 drives the bevel gear 222 to rotate, and the rotation of the bevel gear 222 drives another bevel gear 222 to rotate, and the rotation of another bevel gear 222 drives the second threaded rod 221 to rotate, and the punch 13 is moved left and right by the rotation of the second threaded rod 221. The rectangular slider 226 slides left and right, which can not only prevent the mounting block 2 from rotating, but also support the long slider 214 at the bottom to reduce the force on the threaded rod, making it less likely to break, increasing the service life, facilitating adjustment, improving efficiency and increasing the scope of application.
