Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, in particular to a stamping die for automobile parts which is convenient for replacing the stamping die. Background Art

[0002] A stamping die is a special process equipment used to process materials into parts during stamping. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material to separate or plastically deform it, thereby obtaining the desired parts. The stamping die is designed as a modular component. For example, the upper and lower dies of the die can be designed as independently replaceable modules. This design allows only the damaged or repaired modules to be replaced, rather than the entire die, when part of the die needs to be replaced.

[0003] The introduction of a quick mold change system can significantly reduce the time required to change molds. For example, the use of quick clamping devices or quick connectors can make the installation and unloading of molds faster and more efficient. However, although traditional standardized threads, connection interfaces and fixing holes help to quickly and accurately install new mold parts, they still have defects. Due to the need for disassembly and fixation, the replacement efficiency is not high and cannot be well used in practice.

[0018] In summary, the present invention completes the replacement of the lower mold by rotating the rotating block, and the fixing and releasing of the rotating block can be completed by rotating the rotating plate driven by the dual-axis motor.

DETAILED DESCRIPTION

[0024] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0025] Reference Figure 1-Figure 4 A stamping die for automobile parts that is easy to replace stamping dies, including a base 1, a through hole 2 is opened on the base 1, a rotating motor 3 is fixedly connected to the outer wall of the base 1, the driving end of the rotating motor 3 extends through the through hole 2 and is fixedly connected to a rotating block 4, and lower dies 5 of different specifications are evenly distributed on the surface of the rotating block 4, a stamping table 6 is fixed on the upper side wall of the base 1, an oil cylinder 7 is fixedly arranged on the stamping table 6, and a punching plate 8 is fixedly connected to the driving end of the oil cylinder 7 vertically downward, and the rotating block 4 is driven by the rotating motor 3 to rotate, so that different lower dies 5 are located at the lower side of the punching plate 8. After the lower die 5 is replaced, the rotating block 4 is fixed by the supporting structure and the limiting structure, which ensures the stability of the lower die 5 and realizes the rapid replacement of the lower die 5;

[0026] A supporting structure for supporting the rotating block 4 is provided in the base 1, and the supporting structure includes a supporting plate 9 fixedly connected to the inner wall of the base 1, and a dual-axis motor 10 is fixedly connected to the end of the supporting plate 9, and the driving ends of the dual-axis motor 10 are fixedly connected to a rotating plate 11, and the ends of the two rotating plates 11 are commonly fixedly connected to a supporting shaft 12, and a vertical plate 13 is fixedly connected to the inner bottom wall of the base 1, and the lower end of the vertical plate 13 is rotatably connected to a supporting plate 14, and the supporting plate 14 is U-shaped. When the supporting plate 14 rotates to a horizontal position, it contacts the rotating block 4, and the two legs of the supporting plate 14 are located on the outer side of the lower mold 5 and do not contact the lower mold 5, so as to ensure that the rotating block 4 is supported. , which will not cause damage to the lower mold 5. When the rotating block 4 rotates to replace the lower mold 5, the double-axis motor 10 is started to drive the rotating plate 11 to rotate, so that the rotating plate 11 rotates to be tilted, and the supporting plate 14 also rotates downward. At this time, the rotating motor 3 drives the rotating block 4 to rotate to replace the lower mold 5 located on the lower side of the punching plate 8. After the rotating block 4 is reversed by 90° to complete the replacement, the previously working lower mold 5 is located on the side of the cleaning plate 31, and the double-axis motor 10 is reversed to drive the rotating plate 11 and the supporting shaft 12 to rotate. The supporting shaft 12 then lifts the supporting plate 14 to contact the rotating block 4, and the lower end of the rotating plate 11 is pressed against the bottom wall of the arc-shaped groove 25 to complete the fixing of the rotating block 4.

[0027] The inner bottom wall of the base 1 is provided with an arc-shaped groove 25 that matches the rotation path of the rotating plate 11. When the rotating plate 11 rotates to vertical, the support shaft 12 pushes the support plate 14 to the horizontal to support the rotating block 4. The rotation path of the lower end is arc-shaped, and the arc-shaped groove 25 is provided for adaptation to ensure the smooth rotation of the rotating plate 11. After the rotating plate 11 rotates to vertical, the impact force received by the lower die 5 on the rotating block 4 during the stamping process can be transmitted to the base 1 through the rotating plate 11, and then transmitted to the ground.

[0028] A limiting structure is connected between the base 1 and each rotating plate 11, and the limiting structure includes a reinforcing plate 22 fixed in the base 1, an inserting plate 21 is slidably inserted on the reinforcing plate 22, a connecting plate 18 is fixedly connected to the lower side wall of the inserting plate 21, a return spring 19 is fixedly connected between the connecting plate 18 and the outer wall of the reinforcing plate 22, a moving rod 20 is fixedly connected to the outer wall of the connecting plate 18, and the end of the moving rod 20 passes through the reinforcing plate 22, a right-angled trapezoidal plate 15 is fixedly connected to the outer wall of the rotating plate 11, and the outer wall of the right-angled trapezoidal plate 15 is provided with an inclined surface 16 and a straight surface 17 in contact with the end of the moving rod 20, and the end of the moving rod 20 close to the right-angled trapezoidal plate 15 is arranged in an arc shape, and four slots 32 matching the inserting plates 21 are opened on the outer walls of the front and rear sides of the rotating block 4. Under normal circumstances, the inserting plates 21 are inserted in the slots 32 to limit the rotating block 4 and prevent the rotating block 4 from rotating. The shaft motor 10 drives the rotating plate 11 to rotate so that the support shaft 12 rotates downward, and at the same time drives the right-angled trapezoidal plate 15 to rotate, so that the position where the moving rod 20 contacts the right-angled trapezoidal plate 15 rotates from the inclined surface 16 to the straight surface 17, and then pushes the moving rod 20 outward, so that the end of the plug plate 21 disengages from the slot 32, and ends the limiting of the rotating block 4. At this time, the rotating block 4 can rotate. After the rotating block 4 rotates to replace the lower mold 5, the dual-axis motor 10 drives the rotating plate 11 to reverse. At this time, the right-angled trapezoidal plate 15 rotates to the inclined surface 16 to contact the moving rod 20. In order to adapt to the changes, the moving rod 20 needs to move to the side of the inclined surface 16 under the elastic force of the reset spring 19 until it contacts the inclined surface 16. At this time, the plug plate 21 is inserted into the slot 32 again. During the stamping process, the impact force exerted on the lower mold 5 is transmitted to the base 1 and the ground through the rotating plate 11 and the reinforcing plate 22.

[0029] The base 1 is also provided with a cleaning mechanism for the lower mold 5, which includes a sliding plate slidably inserted at the end of the base 1, the end of the sliding plate is integrally provided with a flange 28, a telescopic spring 29 is fixedly connected between the flange 28 and the outer wall of the end of the base 1, one end of the sliding plate located in the through opening 2 is fixedly connected with a vertically arranged guide groove, a right-angle plate 27 is slidably inserted at the upper end of the guide groove, a return spring is fixedly connected between the lower end of the right-angle plate 27 and the inner bottom wall of the guide groove, and a plurality of cleaning plates 3 are fixedly connected to the outer wall of the end of the right-angle plate 27 1, a plurality of cleaning plates 31 are evenly distributed with bristles on one side close to the lower die 5, a push plate 30 whose end is located on the upper side of the end of the right-angle plate 27 is fixedly connected to the outer wall of the driving end of the oil cylinder 7, an inclined plate is fixedly connected to the outer wall of the reinforcing plate 22 located on the front side, the end of the inclined plate is fixedly connected to the support cylinder 24, the end of the support cylinder 24 is rotatably mounted with a rotating shaft, a swing plate 23 and an L-shaped plate 26 are fixedly connected to the outer wall of the rotating shaft, the end of the swing plate 23 is located at the lower end of the support shaft 12, and the end of the L-shaped plate 26 is located at the lower end of the guide groove.

[0030] When the rotating block 4 is rotated, the double-axis motor 10 drives the rotating plate 11 to rotate, and the rotating motor 3 drives the rotating block 4 to rotate, so that the lower mold 5 after work is located on the left side. When the support shaft 12 continues to rotate downward and contacts the swing plate 23, the swing plate 23 is pushed to rotate downward, and the end of the L-shaped plate 26 rotates to the right, pushing the guide groove to move to the right, so that the bristles contact the lower mold 5 after work. At this time, the oil cylinder 7 is started to drive the push plate 30 to move downward, and the right-angle plate 27 and the cleaning plate 31 are pushed downward, so that the bristles clean the inside of the lower mold 5. After cleaning and replacing the lower mold 5, the double-axis motor 10 drives the rotating plate 11 to rotate vertically. At this time, the support shaft 12 no longer squeezes the swing plate 23, and the sliding plate moves back under the reverse elastic force of the telescopic spring 29. At this time, the cleaning plate 31 is set away from the rotating block 4. When the rotating block 4 is rotated subsequently, the problem of contact between the rotating block 4 and the cleaning plate 31 will not occur. That is, the working process is that the dual-axis motor 10 first drives the rotating plate 11 to rotate a certain amplitude, and then the rotating motor 3 drives the rotating block 4 to rotate to switch the lower mold 5. After that, the dual-axis motor 10 continues to drive the rotating plate 11 to rotate a certain amplitude, so that the support shaft 12 contacts with the swing plate 23, and pushes the L-shaped plate 26 to rotate, so that the bristles contact with the lower mold 5, and the subsequent brushing work of the lower mold 5 can be carried out.

[0031] Furthermore, when the telescopic spring 29 is in a normal state, the end of the right-angle plate 27 can be designed so that its end is not on the same plane as the end of the push plate 30, ensuring that during the stamping process, the push plate 30 does not contact the right-angle plate 27 during movement, ensuring the smooth movement of the punching plate 8.

[0032] In summary, the steps of replacing the lower mold 5 include:

[0033] The dual-axis motor 10 is started to drive the rotating plate 11 to rotate, so that the rotating plate 11 rotates to be tilted, and the supporting plate 14 also rotates downward. The rotating plate 11 drives the right-angled trapezoidal plate 15 to rotate, so that the contact position between the moving rod 20 and the right-angled trapezoidal plate 15 rotates from the inclined surface 16 to the straight surface 17, and then the moving rod 20 is pushed outward, so that the end of the plug plate 21 is disengaged from the slot 32, and the limit of the rotating block 4 is ended. At this time, the rotating motor 3 drives the rotating block 4 to rotate, and the lower mold 5 located at the lower side of the punching plate 8 is replaced. The rotating block 4 rotates 90° in the opposite direction to complete the replacement;

[0034] After the replacement is completed, the dual-axis motor 10 reverses, driving the rotating plate 11 and the support shaft 12 to rotate, and the support shaft 12 then lifts the support plate 14 to contact the rotating block 4, and the lower end of the rotating plate 11 is pressed against the bottom wall of the arc-shaped groove 25. At the same time, the right-angle trapezoidal plate 15 rotates to the inclined surface 16 to contact the moving rod 20. In order to adapt to the changes, the moving rod 20 needs to move to the side of the inclined surface 16 under the elastic force of the reset spring 19 until it contacts the inclined surface 16. At this time, the plug plate 21 is inserted into the slot 32 again to complete the fixation of the rotating block 4.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
