Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] Example 1:

[0028] Reference Figure 1 , Figure 3 , Figure 5 , Figure 7A quick-change die-cutting fixture for automotive parts includes a worktable 1, on which a frame 101 is fixedly connected. It also includes: a support plate 2 symmetrically connected to both ends of the worktable 1, wherein a U-shaped support 202 is connected to both ends of the support plate 2; a die-cutting template 5 inserted into the U-shaped support 202, wherein a groove 203 is provided on the U-shaped support 202, and a locking block 204 is slidably connected within the groove 203; a locking groove 501 corresponding to the locking block 204 is provided on the die-cutting template 5, and the lower end face of the locking block 204 is inclined; a spring 205 fixedly connected between the locking block 204 and the inner wall of the groove 203; a pull rod 206 slidably connected to the U-shaped support 202, and its lower end is fixedly connected to the locking block 204; and a die-cutting block 6, which is lifted and lowered on the frame 101 and used in conjunction with the die-cutting template 5.

[0029] When the punching template 5 needs to be installed, it is inserted into the U-shaped support 202. Because the lower end face of the locking block 204 is inclined, the punching template 5 will press against the locking block 204 during insertion, causing it to slide into the groove 203 and compressing the spring 205. When the punching template 5 is fully inserted, the locking block 204 pops out under the elastic force of the spring 205 and embeds into the locking groove 501 of the punching template 5, quickly and securely fixing the punching template 5. This automatic locking method, compared to traditional bolt fixing, greatly shortens the installation time, improves production efficiency, and avoids damage to the mold caused by frequent bolt use.

[0030] When the punching template 5 needs to be replaced, the operator pulls the lever 206, causing the locking block 204 to slide into the slide groove 203 against the elastic force of the spring 205 until the locking block 204 is completely disengaged from the locking groove 501. At this point, the old punching template 5 can be easily removed without having to spend a lot of time disassembling the bolts as in the traditional method. Then, the new punching template 5 is inserted into the U-shaped support 202, and the above installation steps are repeated to achieve quick replacement. The entire replacement process is simple and convenient, reducing the labor intensity of workers, reducing equipment downtime, thereby improving production efficiency and reducing production costs. After that, the punching block 6 is controlled to descend and cooperate with the punching template 5 to perform punching processing on automotive parts.

[0031] Example 2:

[0032] Reference Figure 1 , Figure 2 A quick-change automotive parts punching fixture is basically the same as in Embodiment 1. Furthermore, a hydraulic telescopic rod 601 is fixedly connected to the frame 101, and the punching block 6 is detachably connected to the telescopic end of the hydraulic telescopic rod 601.

[0033] When punching is required, hydraulic oil is input into the hydraulic telescopic rod 601, causing its piston rod to extend and drive the punching block 6 to move downward until it cooperates with the punching template 5 to complete the punching of the automotive parts. After the punching is completed, the hydraulic telescopic rod 601 is controlled to retract its piston rod, causing the punching block 6 to rise and reset, waiting for the next punching command.

[0034] The hydraulic telescopic rod 601 provides stable and precisely controllable power, enabling the punching block 6 to complete the punching action stably and accurately, improving the quality and precision of the punching process. At the same time, the hydraulic transmission has high reliability and is relatively easy to maintain, reducing equipment downtime and further improving production efficiency.

[0035] Example 3:

[0036] Reference Figure 2 , Figure 6 A quick-change stamping tool for automotive parts is basically the same as in Embodiment 1. Furthermore, a threaded sleeve 602 is fixedly connected to the stamping block 6, and a stud 603 is fixedly connected to the telescopic end of the hydraulic telescopic rod 601. The stud 603 is threadedly connected to the threaded sleeve 602.

[0037] When it is necessary to replace the punching block 6, use the appropriate tool (such as a wrench) to rotate the stud 603 counterclockwise to unscrew it from the sleeve 602, and then remove the old punching block 6. Then, align the sleeve 602 of the new punching block 6 with the stud 603, rotate the stud 603 clockwise to screw it into the sleeve 602, and complete the replacement of the punching block 6. Therefore, when the punching block 6 is worn or needs to be replaced with a different type of punching block 6, the replacement can be completed without complicated operations, which improves the maintenance efficiency of the equipment, reduces equipment downtime, and thus improves the overall production efficiency.

[0038] Example 4:

[0039] Reference Figure 3 , Figure 4 A quick-change stamping tool for automotive parts is basically the same as in Embodiment 1. Furthermore, the support plate 2 is provided with a guide groove 201, and the U-shaped support 202 is slidably connected in the guide groove 201. The support plate 2 is provided with a plurality of adjustment holes 4 that are connected to the guide groove 201 at equal intervals. The adjustment holes 4 are threaded with fixing bolts 401, and the fixing bolts 401 abut against the U-shaped support 202.

[0040] When it is necessary to adjust the distance between the two U-shaped supports 202 according to the width of the punching template 5, the operator uses a wrench or other tools to loosen the fixing bolts 401. As the fixing bolts 401 are loosened, the pressure on the U-shaped supports 202 gradually decreases until no pressure is applied. At this time, the U-shaped supports 202 lose the constraint of the fixing bolts 401 and can slide freely in the guide groove 201. This allows the operator to manually push the U-shaped supports 202 to slide in the guide groove 201 according to the actual width of the punching template 5 and adjust it to a suitable position. Compared with the traditional fixing method, this adjustment method does not require disassembling a large number of parts and can quickly and conveniently change the position of the U-shaped supports 202.

[0041] After sliding the U-shaped support 202 to the appropriate position, the operator uses a wrench or other tools to tighten the fixing bolt 401 again. As the fixing bolt 401 is tightened, it gradually comes into close contact with the U-shaped support 202, applying pressure to the U-shaped support 202 and firmly fixing it in the current position. This ensures that the U-shaped support 202 can stably support the punching template 5 during subsequent punching operations, guaranteeing the smooth progress of the punching work. It also prevents the punching template 5 from shifting due to the loosening of the U-shaped support 202, improving the accuracy and quality of the punching process. At the same time, it reduces the damage to the mold and parts that may be caused by positional deviations, thus lowering production costs.

[0042] The U-shaped support 202 has a limiting hole corresponding to the fixing bolt 401, and the fixing bolt 401 is inserted into the limiting hole;

[0043] During the tightening of the fixing bolt 401, the fixing bolt 401 is gradually inserted into the limiting hole of the U-shaped support 202. As the bolt is tightened, the fixing bolt 401 and the limiting hole are tightly fitted together, so as to achieve a firm fixation of the U-shaped support 202 and prevent the position of the punching template 5 from shifting due to the loosening of the U-shaped support 202, thereby ensuring the accuracy and quality of the punching process. When it is necessary to loosen the U-shaped support 202, the fixing bolt 401 is loosened and it is removed from the limiting hole.

[0044] Example 5:

[0045] Reference Figure 1 , Figure 4 A quick-change die-cutting fixture for automotive parts is basically the same as in Embodiment 1. Furthermore, both ends of the worktable 1 are fixedly connected to electric telescopic rods 3, and the support plate 2 is fixedly connected to the telescopic end of the electric telescopic rods 3.

[0046] When it is necessary to adjust the position of the support plate 2 according to the length of the punching template 5, start the electric telescopic rod 3. If it is necessary to reduce the distance between the two support plates 2, extend the telescopic rod of the electric telescopic rod 3 to push the support plates 2 to move closer to each other. If it is necessary to increase the distance between the two support plates 2, retract the telescopic rod of the electric telescopic rod 3 to move the support plates 2 away from each other until they are adjusted to the appropriate position.

[0047] Once the support plate 2 has moved to the appropriate position, the operator stops the operation of the electric telescopic rod 3. At this point, the position of the support plate 2 is precisely determined, providing a stable and suitable support position for the punching template 5. In subsequent punching operations, this ensures the installation accuracy of the punching template 5, thereby improving the quality and precision of the punching process for automotive parts, reducing the scrap rate caused by template position deviation, increasing production efficiency, and lowering production costs.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
