Description

Technical Field

[0001] The utility model belongs to the technical field of billboard processing, and in particular relates to a positioning punching device for billboard processing. Background Art

[0002] Billboards refer to all outdoor media that convey advertising information. The size of the media depends on the actual environment. When processing billboards, punching devices are often used to punch holes in the billboards to provide installation holes for the billboards to be installed later.

[0003] For example, the Chinese patent with the publication number CN218191977U discloses a billboard side panel punching device, which relates to the technical field of billboard processing equipment, including a desktop, a support frame, a No. 1 motor and a support leg, wherein the support frame is fixedly connected to the middle of both sides of the upper end of the desktop, and the support leg is fixedly connected to the four corners of the lower end of the desktop, and the middle of the two support frames are provided with movable grooves. In the utility model, the operator only needs to place the small billboard to be punched between the clamps driven by the motor, and the fixed rod on the clamp drives the extrusion plate to squeeze downward, and fix the billboard between the extrusion plate and the lower end of the clamp, and the rubber pad under the extrusion plate can protect the squeezed side of the billboard squeezed by the extrusion plate, and can also increase the friction force to prevent slipping when turning over. After fixing, the extrusion plate is driven by the motor to rotate to achieve the effect of turning over. Because it is clamped by the machine, the error after turning over is extremely small, and the re-positioning step can be avoided, thereby improving work efficiency.

[0004] This patent has some shortcomings when in use, such as: in this patent, by setting a clamping mechanism on both sides of the billboard, the clamping mechanism is used to make the billboard suspended, and then punching it. In this process, due to the lack of corresponding support force on the inner side of the lower surface of the billboard, when punching, the billboard is easily deformed under the action of the punching head, that is, the billboard is sunken inward, and the punching fails. In addition, when punching the billboard, the punching device in this patent only directly contacts the billboard through the punching head, and uses the impact force of the punching head to complete the punching of the billboard. In this process, the waste generated by the billboard may rebound and cannot enter the collection box below, thereby affecting the subsequent punching work of the punching head. In view of this, we propose a positioning punching device for billboard processing. Utility Model Content

[0018] In the technical solution, by setting a fixing component, the threaded knob is used to drive the threaded block to move up and down in the inner cavity of the slide slot 1, thereby driving the upper clamping plate to move up and down, thereby fixing and loosening the billboard.

[0026] 2. The positioning punching device for billboard processing has a groove on the upper surface of the L-shaped block. The pressure generated by the punching head when punching the billboard allows the lower clamping plate to fall into the groove and keep the lower surface of the billboard in contact with the upper surface of the mold block.

[0043] See also Figure 1 - Figure 7 As shown, this embodiment provides a positioning punching device for billboard processing, comprising:

[0044] A processing table 1, a stamping wall 2 with a C-shaped structure is fixed to the rear side of the processing table 1, a connecting block 3 is slidably connected inside the stamping wall 2, a hydraulic cylinder 4 is fixed to the upper surface of the stamping wall 2, and the telescopic rod end of the hydraulic cylinder 4 passes through the upper surface of the stamping wall 2 and extends to the bottom to be fixed to the connecting block 3;

[0045] A stamping frame 5, which is fixedly mounted on the front side wall of the connecting block 3, and a pressure-bearing push plate 6 is slidably connected to the inner cavity of the stamping frame 5, and a plurality of evenly distributed stabilizing rods 7 are fixed to the upper surface of the pressure-bearing push plate 6, and a spring 8 is sleeved on the outer side of the stabilizing rod 7, and the two ends of the spring 8 are respectively fixed to the upper surface of the pressure-bearing push plate 6 and the inner cavity top surface of the stamping frame 5, and a stamping support rod 9 is fixed at the center of the lower surface of the pressure-bearing push plate 6, and the bottom end of the stamping support rod 9 passes through the inner cavity bottom surface of the stamping frame 5 and extends to the outside and is fixedly connected to a stamping head 10;

[0046] Two L-shaped blocks 12, which are symmetrically arranged and fixedly mounted on the left and right sides of the upper surface of the processing table 1, respectively, a mold block 13 slides in the convex groove formed by the two L-shaped blocks 12, and a baffle 24 is fixed to the rear side walls of the two L-shaped blocks 12;

[0047] Two limit assemblies, which are symmetrically arranged and both located on the processing table 1, and are used to constrain and limit the mold block 13;

[0048] Two clamping mechanisms, the two clamping mechanisms are respectively located on the two L-shaped blocks 12, the clamping mechanisms include a fixed block 16, an upper clamping plate 17 and a lower clamping plate 18, the fixed block 16 is plugged and matched with the L-shaped block 12, the inner side of the fixed block 16 is provided with an upper clamping plate 17 and a lower clamping plate 18 from top to bottom, wherein the lower clamping plate 18 is fixed to the side wall of the fixed block 16, the upper surface of the L-shaped block 12 is provided with a groove 23 that can accommodate the lower clamping plate 18 to be completely embedded, and the upper surface of the mold block 13 is flush with the upper surface of the L-shaped block 12;

[0049] Two fixing components, the two fixing components are respectively located on the two fixing blocks 16, and are used to control the upper clamping plate 17 to clamp and fix the billboard;

[0050] A collecting tank is provided in the processing table 1, and a collecting box 11 is slidably inserted in the collecting tank;

[0051] The L-shaped block 12 is provided with a second slide groove 14 for accommodating the sliding of the fixed block 16. The fixed block 16 is slidably matched with the second slide groove 14. A second spring 15 is provided in the second slide groove 14 and directly below the fixed block 16. The two ends of the second spring 15 are respectively fixed to the inner wall of the L-shaped block 12 and the fixed block 16.

[0052] A punching hole is provided on the mold block 13, and a feed trough is provided on the lower surface of the mold block 13 and directly below the punching hole. The aperture of the feed trough is larger than the aperture of the punching hole. A through hole connected to the feed trough is provided on the upper surface of the processing table 1, and the collecting trough is connected to the feed trough through the through hole.

[0053] Among them, when using this device, the operator places the billboard in the clamping groove formed by the two upper clamping plates 17 and the lower clamping plate 18, and then starts the fixing component, which drives the corresponding upper clamping plate 17 to move downward, and the upper clamping plate 17 squeezes the billboard and makes the lower surface of the billboard fit with the upper surface of the lower clamping plate 18 until the billboard is completely fixed. At this time, the hydraulic cylinder 4 is started, and the telescopic rod of the hydraulic cylinder 4 moves downward, and pushes the stamping frame 5 to move downward through the connecting block 3. When the punching head 10 contacts the billboard, the punching support rod 9 is subjected to an upward reaction and pushes the pressure-bearing push plate 6 to slide upward in the inner cavity of the punching frame 5. At this time, the plurality of The springs 8 are gradually compressed and tensed, and the top of the stabilizing rod 7 extends out from the through hole on the upper surface of the punching frame 5 to the outside. When the punching head 10 drives the billboard to contact the upper surface of the mold block 13, the punching head 10 punches and punches the billboard at the position of the punching hole of the mold block 13 under the action of the punching hole on the mold block 13; at this time, the waste material is pushed into the lower part of the punching hole of the mold block 13 under the action of the punching head 10. At the moment of completing the punching, the multiple springs 8 generate a reaction force due to the elastic effect, and the elastic potential energy is converted into dynamic potential energy, and the pressure-bearing push plate 6, the punching support rod 9 and the punch are pushed. The punch head 10 moves downward, and at this time the punch head 10 has a strong downward acceleration. Under the action of the punch head 10, the waste material is quickly bounced into the bottom of the punching hole of the mold block 13 and enters the material trough, and then passes through the through hole on the upper surface of the processing table 1 into the collection box 11 in the collection trough, so as to be collected; as the hydraulic cylinder 4 moves in the opposite direction, the punch head 10 moves upward, and at this time the billboard is also moved upward under the action of the spring 2 15 located under the fixed block 16 in the two clamping mechanisms, so as to achieve rapid separation from the mold block 13, and then the operator releases the fixing assembly and punches the next billboard. It is worth adding that in During the above process, when the billboard is displaced downward by the punching head 10, the lower clamping plate 18 falls into the groove 23, and the lower surface of the billboard fits with the upper surface of the mold block 13. Only the position of the billboard located at the punching hole of the mold block 13 is in a suspended state. Due to the support of the upper surface of the mold block 13, the part of the billboard located around the punching hole will not bend or deform under the action of the punching head 10. In addition, when the mold block 13 needs to be replaced and maintained, the operator only needs to press the two limit assemblies downward and slide the mold block 13 forward to slide the mold block 13 out of the convex groove formed by the two L-shaped blocks 12.

[0054] By setting a punching frame 5 and arranging multiple groups of springs 8 in the punching frame 5, the potential energy converted from the huge mechanical energy generated by the multiple groups of springs 8 when restoring the deformation is utilized to push the waste generated when punching the plate into the bottom of the punching hole on the die block 13, and then drop it into the collection box 11, so that the purpose of preventing the waste from rebounding when punching the billboard is achieved, and the problem of the waste being easily ejected along with the punching head 10 during punching and punching in the traditional device is changed, thereby affecting the punching work and efficiency; in addition, by opening a groove 23 on the upper surface of the L-shaped block 12, the punching head 10 is used to punch the billboard The pressure generated during punching allows the lower clamping plate 18 to fall into the groove 23 and keep the lower surface of the billboard in contact with the upper surface of the mold block 13. Due to the support of the upper surface of the mold block 13, the portion of the billboard located around the punching hole will not bend or deform under the action of the punching head 10, which changes the shortcoming of the traditional punching device that when clamping the billboard, the billboard is easily deformed due to the suspended clamping. By setting a limit assembly, the mold block 13 can be stably fixed on the upper surface of the processing table 1, ensuring the accuracy of the billboard during punching.

[0055] Embodiment 2:

[0056] This embodiment provides a positioning punching device for billboard processing, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the fixing component includes:

[0057] A slide groove 19 is provided on the fixed block 16, a bearing seat 20 is fixed in the slide groove 19, a threaded knob 21 is provided on the upper surface of the fixed block 16, and the bottom end of the threaded knob 21 passes through the upper surface of the fixed block 16 and extends to the inner cavity of the slide groove 19 and is coaxially connected to the bearing seat 20, a threaded block 22 slidably connected to the slide groove 19 is threadedly connected to the threaded knob 21, and the threaded block 22 is fixed to the upper clamping plate 17.

[0058] When the fixing assembly is working, the operator turns the threaded knob 21 by hand or with a tool, and the threaded knob 21 rotates. Under the action of the threaded force, the threaded block 22 can move in the vertical direction along the slide groove 19, and at the same time drive the upper clamping plate 17 to move synchronously. When the upper clamping plate 17 moves downward, the billboard can be fixed.

[0059] By setting a fixing component, the threaded knob 21 is used to drive the threaded block 22 to move up and down in the slide groove 19, thereby driving the upper clamping plate 17 to move up and down, thereby fixing and loosening the billboard.

[0060] Embodiment 3:

[0061] This embodiment provides a positioning punching device for billboard processing, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the limiting component includes:

[0062] Two slide grooves 25, the two slide grooves 25 are symmetrically arranged on the upper surface of the processing table 1, the slide grooves 25 are slidably connected to the limit block 26, and the springs 27 are symmetrically arranged in the slide grooves 25 and directly below the limit block 26, and the two ends of the springs 27 are respectively fixed to the limit block 26 and the inner bottom surface of the slide grooves 25;

[0063] The edge of the top of the limiting block 26 facing the front side is in a smooth arc shape.

[0064] Among them, when installing the mold block 13, it is only necessary to place the mold block 13 flat on the upper surface of the processing table 1, and then push the mold block 13 inward. Since the upper edge of the front side of the limit block 26 is in a smooth arc shape, the mold block 13 can squeeze the two limit blocks 26, so that the two limit blocks 26 are retracted into the slide groove three 25. When the mold block 13 completely slides into the convex groove formed by the two clamping mechanisms, under the action of multiple springs three 27, the two limit blocks 26 are ejected from the slide groove three 25 again, and the mold block 13 is limited. It is worth adding that when the mold block 13 falls completely into the convex groove, the inner side wall of the limit block 26 is tightly attached to the front side wall of the mold block 13.

[0065] By setting the limit assembly, it is convenient to install and disassemble the mold block 13, and at the same time, the mold block 13 can be stably constrained in the convex groove formed by the two clamping mechanisms, thereby ensuring the accuracy of the device when punching billboards.

Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
