The device first fixes the plate to be processed on the stamping die, controls the hydraulic cylinder to act through hydraulic pressure, the hydraulic cylinder pushes the fixed plate downward through the piston rod, the fixed plate pushes the stamping head downward through the buffer plate for impact, and through the cooperation of the stamping head and the stamping groove, the stamping and bending of the plate are completed. During the impact process of the stamping head, the generated impact force is offset through the action of the damping seat, so as to effectively enhance the anti-vibration effect of the device and make the stamping process run more smoothly.

[0004] However, in the actual use process, during the process of buffering the impact force, the device only buffers the impact force through the spring inside its damping seat. Therefore, under the influence of the impact force, the spring can only buffer through its own properties and cannot guarantee the damping effect on the upper stamping die. For this reason, an automobile interior decoration processing die with a bending function is proposed to solve the above problems. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides an automobile interior decoration processing die with a bending function, aiming to improve the problem that the spring assembly inside the damping seat alone in the prior art cannot meet the vibration generated by the stamping die when being impacted.

[0023] 1. In the present utility model, through the elastic telescopic rod, support rod, piston rod, damping chamber, connecting rod, and magnetic block provided, when the overall stamping die is impacted, the elastic deformation ability of the elastic telescopic rod itself can buffer the impact force.

[0031] 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 of 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.

[0032] Reference Figures 1 - 3 As an embodiment provided by the present utility model: An automobile interior processing mold with a bending function includes a housing 1, a protection device 3 is arranged on the front surface of the housing 1, a hydraulic cylinder 7 is fixedly connected to the upper surface of the housing 1, a base 4 is fixedly connected to the lower end of the housing 1, a buffer device 2 is arranged inside the base 4, a stamping mold 5 is arranged at the lower end inside the housing 1, and a stamping head 6 is fixedly connected to the output shaft of the hydraulic cylinder 7;

[0033] The buffer device 2 includes an elastic telescopic rod 201, a support rod 202 is fixedly connected to the outer arc surface of the elastic telescopic rod 201, a piston rod 203 is piston-connected to the outer arc surface of the support rod 202, a connecting rod 205 is hinged to the upper end of the outer arc surface of the piston rod 203, a piston rod 203 is piston-connected to the outer arc surface of a damping chamber 204, and the damping chamber 204 is filled with damping liquid, so that the movement of the piston rod 203 and the magnet block 206 can be hindered during their movement. A magnet block 206 is fixedly connected to one end of the piston rod 203 close to the damping chamber 204.

[0034] A through hole is opened at the upper end of the inner surface of the housing 1, so that the hydraulic cylinder 7 can drive the stamping head 6 below to move downward through the movement of its output shaft to complete stamping. A rectangular groove is opened on the front surface of the housing 1, so that each processing component inside the housing 1 can be accommodated. A rectangular groove is opened at the center of the inner surface of the base 4, so that the buffer device 2 can be accommodated inside it. The upper end of the elastic telescopic rod 201 is fixedly connected to the stamping mold 5, and the lower end of the elastic telescopic rod 201 is fixedly connected to the base 4. A through hole is opened at the center of the inner surface of the piston rod 203, so that the piston rod 203 can slide on the outer arc surface of the support rod 202. The upper end of the connecting rod 205 is hinged to the stamping mold 5, so that when the stamping mold 5 is impacted, the whole connecting rod 205 can be synchronously pushed to rotate, and the whole piston rod 203 can be pushed to move into the damping chamber 204. Through holes are opened at both the left and right ends of the damping chamber 204, so that the piston rod 203 can be accommodated to move piston inside it. The outer arc surface of the magnet block 206 is piston-connected to the damping chamber 204. Two groups of such magnet blocks 206 are provided, and the polarities of the adjacent surfaces of the two groups of magnet blocks 206 are the same, so that a repulsive force can be generated when the two magnet blocks 206 approach each other. A plurality of through holes are opened on the inner surface of the magnet block 206, so that the magnet block 206 will not be completely blocked by the damping liquid during its movement inside the damping chamber 204, but will only be hindered by the damping liquid in its movement.

[0035] Reference Figure 1 And Figure 4, the protective device 3 includes a protective plate 303. A magnetic strip 304 is fixedly connected to the inner side of the protective plate 303. The upper end of the housing 1 is made of magnetic metal material. Therefore, when the magnetic strip 304 approaches the top of the housing 1, it can drive the protective plate 303 to be adsorbed to the upper end of the housing 1 through its own magnetism, so that people have enough space to feed and take out automotive interior workpieces inside the housing 1. One end of the protective plate 303 close to the magnetic strip 304 is hinged with a telescopic rod 302, and the lower end of the telescopic rod 302 contacts a limit block 301.

[0036] The outer surface of the protective plate 303 is slidably connected to the housing 1, so its movement trajectory can be limited, and at the same time, it can be ensured that when it falls to the base 4, it can fully block the front end of the housing 1. The telescopic rod 302 is integrally arranged in an inclined shape. One end of the telescopic rod 302 away from the protective plate 303 is hinged to the punching head 6, and the upper end of the limit block 301 is fixedly connected to the punching head 6. One end of the limit block 301 away from the punching head 6 is provided with an inclined surface. Therefore, the maximum inclination angle of the telescopic rod 302 can be limited by the inclined angle of its inclined surface, so as to ensure that the protective plate 303 can descend synchronously with the punching head 6.

[0037] Working principle: When this device is in use, the automotive interior workpiece to be processed needs to be placed on the upper surface of the punching die 5, and the hydraulic cylinder 7 is started to drive the punching head 6 to move downward as a whole to punch the automotive interior workpiece. At this time, during the downward movement of the punching head 6, the protective plate 303 will be driven to move downward as a whole. At the same time, since the telescopic rod 302 is integrally arranged in an inclined shape, the protective plate 303 will preferentially contact the lower base 4 to shield the front surface of the housing 1, so as to prevent metal scraps from splashing and hurting the operator during the punching process. At the same time, after the processing is completed, the punching head 6 will rise accordingly to drive the protective plate 303 to move upward as a whole, thus releasing the shielding of the housing 1. At the same time, the magnetic strip 304 on the back of the protective plate 303 will also drive the protective plate 303 to move upward as a whole and fully release the shielding of the housing 1 due to the mutual attraction between it and the upper end of the housing 1.

[0038] Meanwhile, during the stamping process, the stamping head 6 will come into contact with the lower stamping die 7. At this time, the impact force received at the stamping die will be transmitted to the lower elastic telescopic rod 201. The elastic telescopic rod 201 will buffer the impact force through its own elastic deformation ability. At the same time, during the overall downward movement of the stamping die 7, the connecting rod 205 will also be pushed to cause its overall rotation. At this time, the connecting rod 205 will synchronously drive the piston rod 203 to move into the damping chamber 204 as a whole, and drive the magnetic block 206 to squeeze the damping liquid stored inside the damping chamber 204 as a whole, and form the movement damping when the piston rod 203 moves through the damping liquid 204, so as to effectively reduce and buffer the upper impact force through the ways of buffering and damping. In addition, when the impact force is large, the magnetic blocks 206 on both sides will also approach each other. At this time, since the polarities of the adjacent surfaces of the magnetic blocks 206 on both sides are the same, the repulsive force of the magnetic blocks 206 can further perform secondary buffering on the larger impact force.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
