Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5 This utility model provides an embodiment of an adjustable fine blanking die clamping device, including a plate 31. A support member 11 is fixed to the top of the plate 31. The top of the support member 11 can hold a stamping part 2. The bottom of the stamping part 2 is provided with a positioning groove 22. The top of the support member 11 is provided with a positioning block 111 corresponding to the positioning groove 22. A pressing assembly that moves up and down is provided above the plate 31. The pressing assembly includes a punching rod 36. A punching position 21 is provided in the middle of the stamping part 2. A bridge is provided in the punching position 21. The punching rod 36 can press down the bridge in the punching position 21. The pressing assembly also includes a plate 21. The top of the plate 21 is provided with a through channel. A device that can be installed in the channel is provided with a positioning block 111 corresponding to the positioning groove 22. The pressing clamping block 35 is attached to the top of the stamping part 2. The first adjusting block 3422 is attached to the front and rear sides of the pressing clamping block 35 at the bottom of the second plate 31, and the second adjusting block 3412 is attached to the left and right sides of the pressing clamping block 35 at the bottom of the second plate 31. The positioning block 111 at the top of the support member 11 can correspond to the positioning groove 22 at the bottom of the stamping part 2 to realize the positioning of the stamping part 2. The second adjusting block 3412 and the first adjusting block 3422 squeeze the pressing clamping block 35 to realize the fine adjustment of the position of the pressing clamping block 35, so that the pressing clamping block 35 can accurately press the stamping part 2 to realize the punching rod 36 to break the bridge in the punching position 21.

[0023] Please see Figure 1 - Figure 4In this embodiment, a first fixing block 3421 is provided on the side of the first adjusting block 3422 away from the pressing clamping block 35; a second fixing block 3411 is provided on the side of the second adjusting block 3412 away from the pressing clamping block 35. Adjusting bolts 4 are screw-engaged in both the second fixing block 3411 and the first fixing block 3421. The adjusting bolts 4 can press against the first adjusting block 3422 and the second adjusting block 3412 in the direction of pressing down on the pressing clamping block 35. By turning the adjusting bolts 4, the adjusting bolts 4 can be adjusted relative to the first fixing block 3421. 421 or the second fixing block 3411 moves, thereby controlling the length of the adjusting bolt 4 on both sides of the first fixing block 3421 or the second fixing block 3411. The first adjusting block 3422 and the second adjusting block 3412 are provided with a vertically penetrating clearance channel 3402 on the side away from the pressing clamping block 35. The clearance channel 3402 is provided with a vertically penetrating placement groove 3401 on the side near the pressing clamping block 35. The adjusting bolt 4 is provided with a post 41 on the side facing the pressing clamping block 35. The post 41 is provided with a column on the side facing the pressing clamping block 35. Column 42, column 41 can be placed in the clearance channel 3402, and column 42 can be placed in the placement slot 3401. The diameter of column 42 is larger than that of column 41. By placing column 41 in the clearance channel 3402 and column 42 in the placement slot 3401, the adjusting bolt 4 can pull on the first adjusting block 3422 or the second adjusting block 3412, thus enabling the first adjusting block 3422 or the second adjusting block 3412 to move back and forth. The diameter of column 42 is larger than the width of the clearance channel 3402. The second column 42 cannot pass through the avoidance channel 3402 along the axis of the adjusting bolt 4. The bottom of the pressing clamping block 35 is provided with a downward protruding positioning post 352. The top of the stamping part 2 is provided with a positioning hole 23 corresponding to the positioning post 352. The relative position of the pressing clamping block 35 and the stamping part 2 can be determined by the cooperation of the positioning post 352 and the positioning hole 23, so that the punching rod 36 can accurately press off the bridge of the stamping part 2 without causing damage to the rest. When there is a lot of material in the positioning hole 23, it can also be pressed out by the positioning post 352.

[0024] Please see Figure 2 - Figure 5In this embodiment, a first plate 32 is provided above the second plate 31, and a movable plate 33 is provided between the second plate 31 and the first plate 32. A spring 37 is provided between the first plate 32 and the movable plate 33 to press down the movable plate 33. A pressing clamping block 35 is fixed to the bottom of the movable plate 33. The movable plate 33 is held in place by the spring 37. When the pressing assembly moves upward, the retracted pressing clamping block 35 can be quickly ejected to quickly enter the next stamping process, thereby improving efficiency. The pressing clamping block 35 also includes a top retaining edge 351, which is mapped onto the bottom surface of the movable plate 33. The area of ​​the channel of plate 2 31 is larger than the area of ​​the bottom of the moving plate 33. The pressing clamping block 35 is restricted by the stop 351 to prevent the pressing clamping block 35 from passing through the channel of plate 2 31. A connecting rod 38 is provided between plate 2 31 and plate 1 32. Plate 2 31 and plate 1 32 are relatively fixed. A hydraulic cylinder is provided at the top of the pressing assembly. The output rod of the hydraulic cylinder is relatively fixed with the pressing assembly. The top of plate 2 31 and the bottom of plate 1 32 are connected by the connecting rod 38, so that the connecting rod 38, plate 2 31 and plate 1 32 can move relative to each other. The hydraulic cylinder can output a large downward pressure.

[0025] During operation, the stamped part 2 is placed on the support 11, aligning the positioning groove 22 with the positioning block 111. Then, the hydraulic cylinder is driven to move the pressing assembly downwards. During this movement, the positioning pin 352 aligns with the positioning hole 23, and simultaneously, the positioning pin 352 flushes away excess material from the positioning hole 23. Subsequently, the pressing clamping block 35 and the support 11 clamp the stamped part 2, preventing it from shaking or shifting. As the pressing assembly continues to move downwards, the support 11 presses against the pressing clamping block 35 to prevent it from moving downwards, while the plate 32 drives the punching rod 36 to continue downwards. The bridge within the punching position 21 is broken due to the punching of the punching rod 36, thus completing the punching of the stamped part 2. The spring 37 here is used to provide pressure on the stamped part 2 by the lower clamping block 35. When it is necessary to adjust the first adjusting block 3422 and the second adjusting block 3412, it is only necessary to loosen the bolts of their respective elongated holes and then rotate the adjusting bolt 4 to adjust, thereby changing the position of the lower clamping block 35. After adjustment, the bolts in the elongated holes are tightened. The hydraulic cylinder, its oil circuit, and control method are existing technologies, and their working principle will not be described in detail here.

[0026] Through the above steps, the positioning block 111 at the top of the support 11 can correspond to the positioning groove 22 at the bottom of the stamping part 2, thereby positioning the stamping part 2. The second adjusting block 3412 and the first adjusting block 3422 squeeze the lower clamping block 35 to make fine adjustments to the position of the lower clamping block 35, so that the lower clamping block 35 can accurately press the stamping part 2 to realize that the punching rod 36 breaks the bridge in the punching position 21. This solves the problem that the fine blanking die clamping device in the prior art is prone to deviation of the die position due to deviation, resulting in a decrease in yield and requiring a lot of time to reassemble the device.
