Description

Technical Field

[0001] This utility model relates to the field of edge punching equipment technology, and in particular to a placemat rounded corner punching mold. Background Technology

[0002] In the shaping process of placemats, molds or special tools are used to separate the placemat material along the edges through pressure, resulting in a regular shape. Edge cutting is generally used, mainly for common placemat materials such as silicone, PVC, and felt. Currently, the shaping and cutting of placemats is mostly done manually. Cutting lines are drawn on the placemat beforehand, and a ruler is used to press the material firmly while cutting. A utility knife, scissors, or manual rotary cutter is used to cut along the drawn lines. Thicker materials require more force. At the same time, in order to avoid the appearance of rough edges, a small-step cutting method is also required. Therefore, a single placemat requires multiple processes from measurement and drawing to cutting and polishing, which cannot achieve fast processing and makes it impossible to further improve the efficiency of shaping and cutting the edges of placemats. Utility Model Content

[0003] The purpose of this invention is to provide a placemat rounded corner punching die, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A placemat rounded corner punching die includes a pad plate and a pressure plate. The pad plate is fixedly connected to an external workbench. The pressure plate has several first adjusting slides. A second adjusting slide is formed in the pressure plate between two first adjusting slides. Several rounded corner blades are fixedly connected to the lower end of the pressure plate. A connecting blade is fixedly connected between two adjacent rounded corner blades. A connecting seat is fixedly connected to the pressure plate. A connecting flange is fixedly connected to the connecting seat. The connecting flange is fixedly connected to one end of the piston rod of an external hydraulic device.

[0005] As a further preferred embodiment of this utility model, the rounded blade is L-shaped, and a first abutting block is fixedly connected to one of the included angles of the rounded blade. A first slider is fixedly connected to the first abutting block. The upper surface of the first abutting block located on both sides of the first slider abuts against the lower end of the pressure plate. The first slider is inserted into the corresponding first adjusting slide, so that the rounded blade can be guided to move along the first adjusting slide through the cooperation of the first abutting block and the first slider.

[0006] As a further preferred embodiment of this utility model, the rounded blades located on both sides of the first contact block are fixedly connected to limit blocks. The limit blocks are T-shaped and are used to connect one side of the rounded blade to the corresponding side of the connecting blade, so that when the rounded blade or the connecting blade is adjusted, the rounded blade drives the connecting blade or the connecting blade drives the rounded blade to move synchronously.

[0007] As a further preferred embodiment of this utility model, the lower end of the connecting blade is provided with a bent portion, and the lower end surface of the bent portion is in contact with the lower end surface of the rounded blade, which can realize the length adjustment between the rounded blade and the connecting blade, and the cut surfaces of the rounded blade and the connecting blade are consistent with those of the placemat.

[0008] As a further preferred embodiment of this utility model, a second abutment block is fixedly connected to one side of the connecting blade, and a second slider is fixedly connected to the second abutment block. The upper surface of the second abutment block located on both sides of the second slider abuts against the lower end of the pressure plate, and the second slider is slidably connected in the corresponding second adjusting slide, thereby providing conditions for guiding and fixing the bending part.

[0009] As a further preferred embodiment of this utility model, a stud is fixedly connected to the center of the upper end of the first slider, and a stud is also fixedly connected to the center of the upper end of the second slider. A washer is inserted through the stud, and a nut is threadedly connected to the stud located above the washer. Thus, after the first slider and the first abutment block drive the rounded blade and the second abutment block and the second slider drive the bending part to adjust, the first slider and the second slider can be fixed by the stud and the washer, thereby fixing the rounded blade and the connecting blade.

[0010] As a further preferred embodiment of this utility model, the connecting blades located on both sides of the second contact block are provided with sliding grooves. The sliding grooves are slidably connected to the corresponding limiting blocks to realize the linkage between the rounded blades and the connecting blades. When two of the rounded blades or the connecting blades are adjusted, the remaining rounded blades and the connecting blades can be adjusted synchronously, ultimately achieving the encircling cutting size of several rounded blades and the connecting blades.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the enclosed cutting contour formed by several rounded blades and connecting blades can be synchronously adjusted by the cooperation of the first slider, the second slider, the first slide rail, and the second slide rail. This adapts to the production needs of placemats of different sizes. Relying on hydraulic drive, batch synchronous cutting is achieved, eliminating tedious steps such as manual measurement and drawing. Multiple products can be processed in a short time, reducing reliance on manual labor, balancing production efficiency and product quality, and meeting the actual needs of mass production.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figures 1-4 As shown, the present invention provides a placemat rounded corner punching die, including a pad plate 1 and a pressure plate 2. The pad plate 1 is fixedly connected to an external workbench. The pressure plate 2 has several first adjusting slides 3. The pressure plate 2 between two first adjusting slides 3 has a second adjusting slide 4. Several rounded corner blades 5 are fixedly connected to the lower end of the pressure plate 2. A connecting blade 7 is fixedly connected between two adjacent rounded corner blades 5. A connecting seat 8 is fixedly connected to the pressure plate 2. A connecting flange 9 is fixedly connected to the connecting seat 8. The connecting flange 9 is fixedly connected to one end of the piston rod of an external hydraulic device.

[0016] like Figures 2-4As shown, the rounded blade 5 is L-shaped. A first contact block 10 is fixedly connected to one of the included angles of the rounded blade 5. A first slider 11 is fixedly connected to the first contact block 10. The upper surfaces of the first contact blocks 10 located on both sides of the first slider 11 abut against the lower end of the pressure plate 2. The first slider 11 is inserted into the corresponding first adjusting slide 3, allowing the rounded blade 5 to move along the first adjusting slide 3 through the cooperation of the first contact block 10 and the first slider 11. The rounded blades 5 located on both sides of the first contact block 10 are fixedly connected to limit blocks 6. The limit blocks 6 are T-shaped and are used to realize the movement of the rounded blade 5. One side of the blade is connected to the corresponding connecting blade 7, which facilitates the adjustment of the rounded blade 5 or the connecting blade 7, allowing the rounded blade 5 to drive the connecting blade 7 or the connecting blade 7 to drive the rounded blade 5 to move synchronously. The lower end of the connecting blade 7 is provided with a bending part 12, and the lower end face of the bending part 12 is in contact with the lower end face of the rounded blade 5, which can realize the length adjustment between the rounded blade 5 and the connecting blade 7. The cut surfaces of the rounded blade 5 and the connecting blade 7 on the placemat are consistent. A second abutment block 13 is fixedly connected to one side of the connecting blade 7, and a second slider 14 is fixedly connected to the second abutment block 13. The upper surfaces of the second contact blocks 13 on both sides of the slider 14 abut against the lower end of the pressure plate 2. The second slider 14 is slidably connected in the corresponding second adjusting slide 4, thus providing conditions for guiding and fixing the bending part 12. A stud 15 is fixedly connected to the center of the upper end of the first slider 11, and a stud 15 is also fixedly connected to the center of the upper end of the second slider 14. A washer 16 is inserted through the stud 15, and a nut is threadedly connected to the stud 15 located above the washer 16. Thus, the first slider 11 and the first contact block 10 drive the rounded blade 5, as well as the second contact block 13 and the second slider 14. After the movable bending part 12 is adjusted, the first slider 11 and the second slider 14 can be fixed by the stud 15 and the washer 16, thereby fixing the rounded corner blade 5 and the connecting blade 7. The connecting blade 7 located on both sides of the second abutment block 13 is provided with a sliding groove 17. The sliding groove 17 is slidably connected to the corresponding limit block 6 to realize the linkage of adjustment between the rounded corner blade 5 and the connecting blade 7. When two of the rounded corner blades 5 or the connecting blade 7 are adjusted, the remaining rounded corner blades 5 and the connecting blade 7 can be adjusted synchronously, and finally the encircling cutting size of several rounded corner blades 5 and connecting blades 7 can be achieved.

[0017] It should be noted that this utility model is a placemat rounded corner punching mold. The pad plate 1 is fixed on the external worktable as the bearing reference surface for placemat punching. Then, the placemat to be processed, such as silicone, PVC or felt, is laid flat on the surface of the pad plate 1. Then, the hydraulic drive system is started. The piston rod of the external hydraulic equipment drives the pressure plate 2 to move downward through the connecting flange 9 and the connecting seat 8. At this time, the rounded corner blade 5 and the connecting blade 7 at the lower end of the pressure plate 2 approach the placemat on the pad plate 1 at the same time. The L-shaped rounded corner blade 5 is responsible for punching the rounded corners of the four corners of the placemat, and the connecting blade 7 completes the cutting of the straight edge of the placemat. The bent part 12 of the connecting blade 7 is in contact with the lower end face of the rounded corner blade 5, which can ensure that the entire cutting surface is flat and consistent, and the punching action is completed. The hydraulic equipment drives the pressure plate 2 to return to the starting position, and the punched placemat can be removed. When size adjustment is required to adapt to different specifications, first loosen the nuts on the studs 15 of several first sliders 11 and second sliders 14, so that the nuts on the studs 15 no longer apply pressure to the washers 16. Thus, the washers 16, located on the pressure plate 2, cooperate with the studs 15 to restrict the first sliders 11 and second sliders 14 from falling out of the first adjustment slide 3 and the second adjustment slide 4, while ensuring that the first sliders 11 slide in the first adjustment slide 3 and the second sliders 14 slide in the second adjustment slide 4. Then, simply push the studs 15 on two of the first sliders 11 or the studs 15 on two of the second sliders 14. Since the sliding groove 17 of the connecting blade 7 is in sliding engagement with the limiting block 6 of the rounded blade 5, when any rounded blade 5 or connecting blade 7 is adjusted, the other parts will move in tandem, thereby adjusting the encircling cutting contour. After adjustment, tighten the nuts on the studs 15, and lock the first sliders 11 and second sliders 14 through the washers 16 to fix the position of the rounded blades 5 and the connecting blades 7.
