The stamping head is driven by a cylinder to form the steel plate under the action of the stamping groove of the die base. However, the existing stamping head has a simple structure, which easily leads to incomplete groove forming and poor stamping effect, making it difficult to guarantee the forming quality of the sliding groove. Therefore, it needs to be improved. Utility Model Content

Detailed Implementation

[0021] Example

[0022] refer to Figures 1 to 5 The special processing equipment for the lifting slider groove of the die casting machine gantry described in this embodiment includes a base 1. A mold base 2 is fixedly connected to the top of the base 1. A stamping groove 3 is opened on the top of the mold base 2. A fixing frame 8 is fixedly connected to the top of the base 1. A cylinder 9 is fixedly connected to the top of the fixing frame 8. A shock absorption component 11 is provided at the output end of the cylinder 9. An assembly plate 10 is fixedly connected to the bottom end of the shock absorption component 11. A stamping head assembly 4 is provided at the bottom end of the assembly plate 10, and there are two stamping head assemblies 4. An adjustment component 5 is provided on one side of the assembly plate 10. The stamping head assembly 4 is slidably connected to the lower side of the assembly plate 10 through the adjustment component 5.

[0023] refer to Figure 3-4The adjusting component 5 includes a motor 51, which is fixedly connected to one side of the assembly plate 10. A worm gear 52 is fixedly connected to the output end of the motor 51. A worm wheel 53 is meshed with one side of the worm gear 52. A double-acting screw 54 is fixedly connected to one side of the worm wheel 53. The double-acting screw 54 is rotatably connected inside the assembly plate 10. Screw blocks 55 are threadedly connected to both sides of the outer surface of the double-acting screw 54. The screw blocks 55 are slidably connected inside the assembly plate 10. The bottom end of the screw blocks 55 is fixedly connected to the stamping head assembly 4. By setting the adjusting component 5, when in use, the motor 51 is started, and the motor 51 drives the worm gear 52 to rotate. The worm gear 52 drives the worm wheel 53 and the double-acting screw 54 to rotate synchronously. When the double-acting screw 54 rotates, the screw blocks 55 on both sides slide in opposite directions along the screw axis, thereby causing the two stamping head assemblies 4 to move away from each other by a certain distance before the pressing operation, ensuring better sliding grooves formed by the steel plate.

[0024] refer to Figure 3 The assembly plate 10 has limit grooves 6 on both sides inside. Limit blocks 7 are slidably connected inside the limit grooves 6. One side of the limit block 7 is fixedly connected to one side of the screw block 55. By setting the limit grooves 6 and the limit blocks 7, when the bidirectional lead screw 54 drives the screw block 55 to slide, the screw block 55 drives the limit block 7 to slide synchronously along the limit grooves 6. The limit block 7 is always embedded in the limit grooves 6, restricting the movement trajectory of the screw block 55 and avoiding the stamping position distortion caused by the rotation of the screw block 55.

[0025] refer to Figure 5 The stamping head assembly 4 includes a stamping base 41, which is fixedly connected to the bottom end of the screw block 55. A first spring 43 is fixedly connected to the bottom end of the stamping base 41, and a bonding plate 42 is fixedly connected to the bottom end of the first spring 43. A mating block 46 is fixedly connected to one side of the bonding plate 42. A mating groove 45 is formed on one side of the stamping base 41, and the mating block 46 is movably connected to the mating groove 45. Guide blocks 44 are fixedly connected to both sides of the mating plate 42 at the mating block 46. The side-sliding connection is inside the stamping seat 41; by setting the stamping head assembly 4, during stamping, the bonding plate 42 first contacts the steel plate, and as the assembly plate 10 moves down, the first spring 43 is compressed, generating elastic force to make the bonding plate 42 tightly press against the surface of the steel plate, which can reduce the gap during the stamping process and improve the smoothness of the groove surface. At the same time, the mating block 46 slides along the mating groove 45, which facilitates the side of the stamping seat 41 to bond with the steel plate, and the guide block 44 slides along the inside of the stamping seat 41 to ensure that the bonding plate 42 moves vertically downward. After the stamping is completed, the spring rebounds and drives the bonding plate 42 to reset.

[0026] refer to Figure 2The shock absorption assembly 11 includes a first transmission rod 111, which is fixedly connected to the output end of the cylinder 9. A second spring 112 and a damper 113 are fixedly connected to the bottom end of the first transmission rod 111. A second transmission rod 116 is fixedly connected to the common end of the second spring 112 and the damper 113. The bottom end of the second transmission rod 116 is fixedly connected to the top end of the mounting plate 10. Slide rods 114 are fixedly connected to both sides of the bottom end of the first transmission rod 111. A slide cylinder is fixedly connected to the top end of the second transmission rod 116. 115. One side of the slide rod 114 is slidably connected to the inside of the slide cylinder 115. By setting the shock absorption component 11, during stamping, the cylinder 9 pushes the first transmission rod 111 downward, the second spring 112 and the damper 113 are compressed to absorb the impact force, and the slide rod 114 slides synchronously along the slide cylinder 115. After stamping, the spring rebounds and drives the transmission rod to reset, and the slide rod 114 moves upward. The sliding cooperation between the slide rod 114 and the slide cylinder 115 ensures that the first and second transmission rods 116 always move along the axial direction, avoids deviation during shock absorption, and ensures the accuracy of the stamping direction.

[0027] refer to Figure 1 Guide rods 12 are fixedly connected to both sides of the top of the assembly plate 10. One side of the guide rod 12 slides through one side of the fixed frame 8. By setting the guide rod 12, when the cylinder 9 drives the assembly plate 10 to move up and down, the guide rod 12 slides synchronously with the assembly plate 10 along the fixed frame 8, always maintaining a vertical state. This prevents the assembly plate 10 from swaying or tilting left and right due to uneven force during the stamping process, ensuring that the stamping head assembly 4 acts vertically on the steel plate and avoiding skewing or dimensional deviation in the groove forming.

[0028] Operating principle and advantages: The steel plate to be processed is placed stably above the stamping groove 3 of the top die base 2 of the base 1, ensuring that the steel plate covers the stamping groove 3 and is centered. Then, the stamping operation is started. The cylinder 9 at the top of the fixed frame 8 is activated. The output end of the cylinder 9 pushes the first transmission rod 111 of the shock absorption assembly 11 to move down. The first transmission rod 111 drives the second transmission rod 116 and the assembly plate 10 to move down through the second spring 112 and the damper 113. During the downward movement, the guide rods 12 on both sides of the top of the assembly plate 10 slide along the fixed frame 8 to prevent the assembly plate 10 from swaying or tilting, ensuring that the stamping head assembly 4 acts vertically on the steel plate. During stamping, the contact plate 42 of the stamping head assembly 4 contacts the steel plate first and continues to move down with the assembly plate 10. As the first spring 43 is compressed, it generates elastic force, causing the bonding plate 42 to press tightly against the surface of the steel plate, reducing the stamping gap and improving the smoothness of the groove surface. This facilitates the side of the stamping seat 41 to adhere to the steel plate. Combined with the sliding guidance of the guide block 44, it ensures that the bonding plate 42 always moves in the vertical direction, preventing deviation during the stamping process and ensuring the forming accuracy of the slide groove. After one stamping, the motor 51 drives the worm 52 to rotate, and the worm 52 drives the meshing worm wheel 53 and the bidirectional lead screw 54 to rotate synchronously. The screw blocks 55 connected by threads on both sides of the bidirectional lead screw 54 slide in the opposite direction along the lead screw axis, thereby driving the two stamping head assemblies 4 to move away from each other and apply force to the steel plate, thus enabling the steel plate slide groove to be formed more fully.
