Description

Technical Field

[0001] The present invention relates to the technical field of punching, and particularly to a continuous punching device for door and window plates. Background Art

[0002] Door and window plates refer to various materials used for producing parts such as door and window frames, panels, and window sashes. These materials have different physical and chemical properties to meet various requirements such as building structures, decorative styles, and climate adaptability. Door and window plates not only need to have sufficient strength and durability but also certain aesthetics and functions. During the processing of door and window plates, operations such as punching and grooving may be required, and punching equipment may be needed.

[0003] For example, a punching machine for plates used in office furniture disclosed in the patent with the publication number CN213674357U can punch plates, but it not only does not have the function of continuous punching but also does not have the function of scratching the punched parts. As a result, when the punch contacts the plate for punching, the internal stress of the plate during punching cannot be eliminated, reducing the punching effect. Therefore, there is an urgent need to design a continuous punching device for door and window plates. Summary of the Invention

Specific embodiments

[0032] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to the attached Figure 1 - attached Figure 8 , a continuous punching device for door and window plates, including a bottom plate 1, and further including: a U-shaped frame 2, a support plate 3, a connecting block 7, a moving assembly and a scratching assembly. The U-shaped frame 2 is fixedly installed above the bottom plate 1. There are two support plates 3, and the two support plates 3 are respectively fixedly installed at both ends of the top of the bottom plate 1. An elastic clamping plate 13 is horizontally fixedly installed at the end of one of the support plates 3 close to the U-shaped frame 2. The connecting block 7 is arranged below the horizontal side of the U-shaped frame 2. A punch 8 is vertically fixedly installed at the bottom of the connecting block 7, and a hydraulic rod 4 connected to the top of the connecting block 7 is installed at the top of the horizontal side of the U-shaped frame 2. The moving assembly is arranged on the bottom plate 1 and the connecting block 7, and the moving assembly is used to move the door and window plates. The scratching assembly is arranged on the U-shaped frame 2 and the connecting block 7, and the scratching assembly is used to scratch the door and window plates to facilitate subsequent punching;

[0035] The above-mentioned device can first punch two holes in the plate and then perform continuous equidistant hole punching without manual measurement, which makes the efficiency of continuous equidistant hole punching of the plate high. Moreover, before the punch 8 punches the hole, it can also scratch the part of the plate that needs to be punched, ensuring the convenience of subsequent punching by the punch 8.

[0036] Please refer to the attached Figure 2 - attached Figure 8 In a preferred embodiment, the moving component includes: a limit block 14, which is slidably arranged on the top of the bottom plate 1. One end of the top of the limit block 14 is provided with a first slope 15. A second spring rod 10 is horizontally and fixedly installed on the side surface of the connecting block 7.

An electric telescopic rod is fixedly installed inside the corresponding vertical side of the U-shaped frame 2, and the output end of the electric telescopic rod is fixedly installed on the side surface of the limit block 14.

[0037] Furthermore, the electric telescopic rod drives the limit block 14 to move, so that the limit block 14 and the moving column 9 are located in the same vertical plane. Due to the setting of the first slope 15, when the moving column 9 contacts the first slope 15, it will cause the moving column 9 to move to the left and generate a pulling force on the second spring rod 10. The leftward movement of the moving column 9 will drive the plate to move to the left, and the setting of the elastic clamping plate 13 cooperates with the punched holes to ensure that the plate can only move to the left.

[0038] Please refer to the attached Figure 1 - attached Figure 4 In a preferred embodiment, a blanking block is fixedly installed on the top of the bottom plate 1, and a through second blanking groove 16 is opened on the top of the blanking block.

A movable rod 31 is rotatably installed at the end of the cross block 30, and the end of the movable rod 31 is rotatably installed at the top of the connecting plate 5. A rotating block 21 is rotatably installed at the bottom of the connecting plate 5, and the center of the top of the rotating block 21 is fixedly installed at the center of the bottom of the first bevel gear 32 through a connecting shaft. A sliding rod 22 is slidably sleeved on the rotating block 21, and an L-shaped plate 24 is fixedly installed at the top of the sliding rod 22. A straight spring 23 is sleeved on the surface of the sliding rod 22, and both ends of the straight spring 23 are respectively fixedly installed on the side of the vertical side of the L-shaped plate 24 and the side of the rotating block 21. Two symmetrically arranged first sliding columns 27 are horizontally fixed at the bottom of the connecting plate 5, and sleeve rings 28 are slidably sleeved on the surfaces of the two first sliding columns 27. A second sliding column 29 is fixedly installed between the two sleeve rings 28. A sliding block 25 is slidably sleeved on the surface of the second sliding column 29, and the bottom of the horizontal side of the L-shaped plate 24 is rotatably installed at the center of the top of the sliding block 25. A cutting tool 26 is vertically fixedly installed at the bottom of the sliding block 25;

[0041] Preferably, it can scratch the position to be punched, improve the accuracy, reduce deformation and breakage, reduce the impact force, improve the surface quality and improve the production efficiency.

[0042] The working principle of the present invention: First, place the plate that needs to be continuously punched for doors and windows on the support plate 3, and then drive the punch 8 to move downward through the hydraulic rod 4 to punch a hole in the plate first, and then push the plate to move. This movement needs to make the first hole on the plate directly below the moving column 9;

[0043] Next, start the hydraulic rod 4 to drive the connecting block 7, the punch 8 and the second spring rod 10 to move downward. The downward movement of the second spring rod 10 drives the moving column 9 to move downward and enter the first hole punched by the punch 8. At this time, the moving column 9 will contact the limiting block 14, and then the downward movement of the punch 8 will punch a second hole in the plate.

[0044] Then, drive the limiting block 14 to move through the electric telescopic rod so that the limiting block 14 and the moving column 9 are in the same vertical plane. Then, make the hydraulic rod 4 drive the connecting block 7 and its connecting components to move downward together. Due to the setting of the first slope 15, when the moving column 9 contacts the first slope 15, it will make the moving column 9 move to the left and cause the second spring rod 10 to generate a pulling force. The leftward movement of the moving column 9 will drive the plate to move to the left. When the moving column 9 separates from the first slope 15, the moving column 9 will only move vertically downward. At this time, the plate will no longer move. Further, the downward movement of the punch 8 will punch a third hole in the plate. At the same time, the elastic clamping plate 13 will be located inside the first hole. Then, the vertical side surface of the elastic clamping plate 13 will prevent the plate from moving to the right. When the hydraulic rod 4 drives the connecting block 7 to move upward, it drives all parts to reset. When the second spring rod 10 and the moving column 9 move upward, they will not drive the plate to move to the right.

[0045] In addition, when the connecting block 7 moves downward, it will also drive the rack 17 to move downward and the cross block 30 to move to the right. The rightward movement of the cross block 30 drives the connecting plate 5 to move downward through the movable rod 31. The downward movement of the connecting plate 5 drives the cutting knife 26 to move downward. The downward movement of the rack 17 will contact the first gear 18 and drive the first gear 18 to rotate. The rotation of the first gear 18 drives the rotating rod 19 to rotate. The rotation of the rotating rod 19 drives the second bevel gear 33 to rotate. The rotation of the second bevel gear 33 drives the first bevel gear 32 to rotate. The rotation of the first bevel gear 32 drives the rotating block 21 to rotate. The rotation of the rotating block 21 drives the sliding rod 22 to rotate. Due to the limiting effect of the two first sliding columns 27 on the collar 28 and the second sliding column 29 and the limiting effect of the second sliding column 29 on the slider 25 and the L-shaped plate 24, the slider 25 will drive the cutting knife 26 to draw a trace on the plate that is adapted to the size of the punch 8, ensuring the convenience and punching quality when the punch 8 punches the plate subsequently.

[0046] Finally, start the hydraulic rod 4 to drive the connecting block 7 and other connecting components to move downward together. In summary, after that, the downward movement of the moving column 9 will drive the plate to automatically move to the left by a certain distance, and then automatically make the punch 8 punch the plate. Since the right end of the elastic clamping plate 13 is a slope, the plate will move smoothly to the left and will not move to the right. In summary, by reciprocating in turn, continuous punching of the plate can be carried out, and the punch 8 is convenient and fast, thereby improving the use effect of the equipment.

[0047] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
