Description

Technical Field

[0001] The invention belongs to the technical field of stamping devices, and in particular relates to a door panel stamping device. Background Art

[0002] Stamping is a forming process that uses a press and a die to apply external force to plates, strips, tubes, and profiles, causing them to plastically deform or separate, thereby obtaining a workpiece (stamping part) of the desired shape and size. During the stamping process of door panels, it is often necessary to manually move the door panel between the upper and lower dies of the stamping device, and the stamping process is completed through the relative movement of the upper and lower dies.

[0003] During the stamping process, the workpiece punched out of the door panel needs to be removed, otherwise it will affect the subsequent stamping of the door panel. Currently, most of the materials are taken out manually by the staff. However, during processing, the upper and lower molds are constantly separated and combined, so the staff are easily injured in the process of taking the materials, which in turn causes major safety accidents.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a door panel punching device. Summary of the Invention

[0005] The object of the present invention is to provide a door panel punching device to solve the problem of inconvenience in material removal during the above-mentioned existing door panel punching process.

[0006] In order to achieve the above-mentioned purpose, the technical solution provided by one embodiment of the present invention is as follows:

[0007] A door panel punching device, comprising: an operating table, a punching assembly and a discharge mechanism;

[0008] A lower punching die is provided on the operating table;

[0009] The stamping assembly is arranged above the operating table, and the stamping assembly includes an upper stamping die, and the upper stamping die is arranged directly above the lower stamping die, and a traction rope is connected to the upper stamping die;

[0010] The discharge mechanism is arranged between the lower stamping die and the upper stamping die, and the discharge mechanism includes a pair of support push rods, one end of the support push rod is connected to the discharge push plate, and the end of the traction rope away from the upper stamping die is fixedly connected to the discharge push plate.

[0011] Furthermore, a discharge chute is carved on the operating table to assist in unloading the workpiece. The workpiece is pushed into the discharge chute by the unloading push plate, and then the workpiece slides down, so that the staff no longer need to reach between the lower stamping die and the upper stamping die to take the material, thereby reducing the probability of injury to the staff.

[0012] Furthermore, a support frame is installed on the operating table to support a pair of stamping cylinders, so that the stamping cylinders are not easy to shake, thereby increasing the stability of the upper stamping die lifting and lowering, thereby ensuring the stability of the stamping door panel, and providing support force for a pair of rotating support columns;

[0013] Several stamping cylinders are installed on the support frame to control the extension and retraction of the piston push rod, thereby providing power for the stamping door panel. The stamping cylinder is provided with a piston push rod to support the upper stamping die and drive the upper stamping die to move up and down. The other end of the piston push rod is fixedly connected to the upper stamping die.

[0014] Furthermore, a pair of rotating support columns are installed on the support frame for supporting a pair of winding wheels so that the winding wheels are not easy to fall off. The rotating support columns are provided with winding wheels for winding the traction rope and guiding the direction of the traction rope, so that when the upper stamping die descends, the blanking push plate can be pulled closer to the shrinking frame, and the traction rope is wound around the pair of winding wheels;

[0015] A fixed bearing is connected between the rotating support column and the winding wheel for fixing the winding wheel so that the winding wheel is not easily moved and the free rotation of the winding wheel is facilitated so that the rotation of the winding wheel is not easily affected by the rotating support column, thereby making the sliding of the traction rope less easily affected.

[0016] Furthermore, the operating table is provided with a retraction frame, in which a pair of retraction grooves are cut to provide space for retracting the support push rod, thereby facilitating the movement of the blanking push plate. A limiting slide is provided in the retraction groove, which is used to limit the support push rod so that the support push rod is not easy to fall off and has the function of pushing the support push rod to move. One end of the support push rod away from the blanking push plate is fixedly connected to the limiting slide.

[0017] A pushing spring is connected between the limiting slide and the supporting push rod, which is used to push the limiting slide so that the unloading push plate is no longer subjected to the tension of the traction rope. The pushing spring can push the limiting slide to move, thereby pushing the supporting push rod and the unloading push plate through the limiting slide, and then the unloading push plate pushes the punched workpiece into the discharge chute, realizing the function of automatic unloading.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] By setting up the corresponding mechanism of the door panel stamping device, the present invention no longer requires workers to manually take out materials, so that the upper and lower molds can automatically unload materials during the stamping process, thereby reducing the probability of workers being injured, and can effectively improve the stamping efficiency of the door panel, reducing unnecessary trouble for users.

[0028] The present invention will be described in detail below with reference to the various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0029] The present invention discloses a door panel punching device, referring to Figures 1-6 As shown, it includes: an operating table 1, a stamping component 2 and a discharge mechanism 3.

[0030] refer to Figure 1As shown, a lower stamping die 101 is provided on the operating table 1 for cooperating with the upper stamping die 201 to stamp the door panel. A discharge chute 102 is opened on the operating table 1 for assisting in unloading the workpiece. The workpiece is pushed into the discharge chute 102 by the unloading push plate 302, and then the workpiece is made to slide, so that the staff no longer needs to reach between the lower stamping die 101 and the upper stamping die 201 to take the material, thereby reducing the probability of injury to the staff.

[0031] refer to Figure 1-Figure 5 As shown, the stamping assembly 2 is arranged above the operating table 1, and the stamping assembly 2 includes an upper stamping die 201. The upper stamping die 201 is arranged directly above the lower stamping die 101, so that the upper stamping die 201 can cooperate with the lower stamping die 101 to stamp the door panel. A traction rope 202 is connected to the upper stamping die 201, which is used to pull the blanking push plate 302 to move, so that the upper stamping die 201 can move the blanking push plate 302 out from above the lower stamping die 101 when pressing down, so as to not easily affect the stamping door panel.

[0032] refer to Figure 1-Figure 5 As shown, a support frame 203 is installed on the operating table 1 to support a pair of stamping cylinders 204, so that the stamping cylinders 204 are not easy to shake, thereby increasing the stability of the lifting and lowering of the upper stamping die 201, thereby ensuring the stability of the stamping door panel, and providing support force for a pair of rotating support columns 206.

[0033] refer to Figure 1-Figure 4 As shown, a number of stamping cylinders 204 are installed on the support frame 203, which are used to control the extension and retraction of the piston push rod 205, thereby providing power for stamping the door panel. The stamping cylinder 204 is provided with a piston push rod 205, which is used to support the upper stamping die 201 and drive the upper stamping die 201 to move up and down. The other end of the piston push rod 205 is fixedly connected to the upper stamping die 201.

[0034] refer to Figure 1-Figure 5 As shown, a pair of rotating support columns 206 are installed on the support frame 203 for supporting a pair of winding wheels 207 so that the winding wheels 207 are not easy to fall off. The rotating support columns 206 are provided with winding wheels 207 for winding the traction rope 202 and guiding the direction of the traction rope 202, so that when the upper stamping die 201 descends, it can pull the blanking push plate 302 closer to the shrinking frame 303, and the traction rope 202 is wound around the pair of winding wheels 207.

[0035] Among them, a fixed bearing 208 is connected between the rotating support column 206 and the winding wheel 207, which is used to fix the winding wheel 207, so that the winding wheel 207 is not easy to move, and facilitates the free rotation of the winding wheel 207, so that the rotation of the winding wheel 207 is not easily affected by the rotating support column 206, thereby making the sliding of the traction rope 202 less likely to be affected.

[0036] refer to Figures 1-6 As shown, the discharge mechanism 3 is arranged between the lower stamping die 101 and the upper stamping die 201. The discharge mechanism 3 includes a pair of supporting push rods 301, which are used to support the discharge push plate 302 and drive the discharge push plate 302 to move. One end of the supporting push rod 301 is connected to the discharge push plate 302, which is used to push the workpiece after stamping to discharge. The end of the traction rope 202 away from the upper stamping die 201 is fixedly connected to the discharge push plate 302, so that the traction rope 202 can pull the discharge push plate 302.

[0037] refer to Figures 1-6 As shown, a retraction frame 303 is provided on the operating table 1, and a pair of retraction grooves are opened in the retraction frame 303 to provide space for retracting the support push rod 301, thereby facilitating the movement of the blanking push plate 302. A limiting slide 304 is provided in the retraction groove to limit the support push rod 301 so that the support push rod 301 is not easy to fall off, and has the function of pushing the support push rod 301 to move. The end of the support push rod 301 away from the blanking push plate 302 is fixedly connected to the limiting slide 304.

[0038] refer to Figure 6 As shown, a pushing spring 305 is connected between the limiting slide 304 and the supporting push rod 301, which is used to push the limiting slide 304 so that the unloading push plate 302 is no longer subjected to the tension of the traction rope 202. The pushing spring 305 can push the limiting slide 304 to move, thereby pushing the supporting push rod 301 and the unloading push plate 302 through the limiting slide 304, and then the unloading push plate 302 pushes the punched workpiece into the discharge chute 102, realizing the function of automatic unloading.

[0039] When in use, the staff first starts the stamping cylinder 204, so that the stamping cylinder 204 controls the piston push rod 205 to extend, and the piston push rod 205 pushes the upper stamping die 201 to descend a short distance. When the upper stamping die 201 descends, it pulls the traction rope 202, thereby pulling the blanking push plate 302 back through the traction rope 202, so that the blanking push plate 302 moves out from above the lower stamping die 101. Then the staff places the door panel on the lower stamping die 101 and starts the stamping cylinder 204 again.

[0040] The stamping cylinder 204 controls the piston push rod 205 to extend, so that the piston push rod 205 can push the upper stamping die 201 down, and then stamp on the door panel to achieve the stamping operation. When the stamping is completed, the piston push rod 205 drives the upper stamping die 201 to rise. After the upper stamping die 201 rises, it will no longer pull the traction rope 202, so that the traction rope 202 no longer has a pulling force on the blanking push plate 302.

[0041] At this time, the push spring 305 will push the limiting slide 304 to move, and the limiting slide 304 will push the supporting push rod 301 and the blanking push plate 302 to move, so that the blanking push plate 302 can move to the top of the lower stamping die 101, and then push the workpiece to the discharge chute 102, which is convenient for the staff to take out. The staff no longer needs to reach between the lower stamping die 101 and the upper stamping die 201 to take the material, thereby reducing the probability of injury to the staff.

[0042] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0043] By setting up the corresponding mechanism of the door panel stamping device, the present invention no longer requires workers to manually take out materials, so that the upper and lower molds can automatically unload materials during the stamping process, thereby reducing the probability of workers being injured, and can effectively improve the stamping efficiency of the door panel, reducing unnecessary trouble for users.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
