Description

Technical Field

[0001] This utility model relates to the field of cutting machines, and in particular to a precision four-column cutting machine. Background Technology

[0002] In traditional cutting and processing of non-metallic materials such as foam, cardboard, textiles, plastics, leather, rubber, packaging materials, flooring materials, carpets, fiberglass, and cork, most of the cutting is done manually with shears. Cutting machines are machines that use the force of machine movement to press on a die to punch non-metallic materials.

[0003] Existing cutting machines require the material to be cut to be placed on the processing plane during use, but they lack a fixing structure. In the actual cutting process, if the material shifts, the quality of the corresponding processed product will also be defective. In view of this, we propose a precision four-column cutting machine. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a precision four-column cutting machine, which can effectively solve the problem that the existing cutting machine requires the material to be cut to be placed on the processing plane, but lacks a fixing structure. In the actual cutting process, if the material is deviated, the quality of the corresponding processed product will also be defective.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precision four-column cutting machine includes a worktable and movable plates that are symmetrically connected to both sides of the worktable.

[0007] In addition, the frame erected on the upper side of the workbench has a first inclined surface at both ends, and overlapping blocks are fixedly installed at both ends of the movable plate. A second inclined surface is provided on the upper side of the overlapping blocks, and the first inclined surface and the second inclined surface slide together.

[0008] It also includes a clamping plate fixedly installed at the inner end of the movable plate. When the first inclined plane and the second inclined plane slide relative to each other, the corresponding clamping plate will clamp the material.

[0009] Preferably, the clamping plate is elastically connected to the mounting plate on the top surface of the worktable by a spring, and the moving plate slides in a groove on the top surface of the worktable.

[0010] Preferably, the device includes a capsule disposed within a chute, the capsule being filled with an inert gas, which is compressed by the moving plate when it slides within the chute; and two cavities located inside the worktable, the capsule being connected to the cavities via connecting grooves, and a rubber strip disposed on the upper side of the cavities and located on the top surface of the worktable.

[0011] Preferably, the rubber strip has multiple air vents spaced linearly at equal intervals, and a valve is provided inside each air vent.

[0012] Preferably, a cutting blade is fixedly installed at the lower end of the frame. In the horizontal direction, the cutting blade is located between the middle of two rubber strips. The frame slides in cooperation with the limiting plate fixedly installed on the top surface of the workbench. It also includes symmetrical clearance grooves opened on the top surface of the frame and contact plates fixedly installed on the frame. The inner wall of the clearance groove slides in cooperation with the outer wall of the overlapping block.

[0013] Preferably, it also includes an arc-shaped frame movably connected to the frame body, the arc-shaped frame slidingly engaging with a drive shaft fixedly mounted on the frame body, and the lower end of the arc-shaped frame being at the same level as the bottom surface of the cutting blade.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model, through a frame movably connected to the upper part of the workbench and clamping plates slidably connected to both sides of the workbench, can adaptively fix the material in the lateral direction during cutting. Furthermore, the connection between the bladder and the cavity allows for automatic clamping of the material in the longitudinal direction during cutting, ensuring the accuracy of the cutting.

The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

Therefore, the above terms should not be construed as limitations on this invention.

[0029] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0030] See attached document Figure 1-4As shown, a precision four-column cutting machine includes a worktable 100 and movable plates 200 slidably connected to both sides of the worktable 100 in a symmetrical structure; and a frame 300 mounted on the upper side of the worktable 100. A cutting blade 310 is fixedly installed at the lower end of the frame 300. Specifically, in this application, the cutting blade 310 is fixedly installed at the lower side of the frame 300, and a drive shaft 330 is fixedly installed at the upper end of the frame 300. The drive shaft 330 is used to adjust the vertical distance between the frame 300 and the worktable 100. When the cutting blade 310 fixedly installed at the lower side of the frame 300 cuts the material on the top surface of the worktable 100, the corresponding drive shaft 330 will move upward. The above describes the cutting method of the cutting machine in this application.

[0031] Based on the above-mentioned cutting, since the position of the frame 300 relative to the workbench 100 in the vertical direction is fixed, common cutting machines require manual adjustment of the material's posture during cutting to ensure accurate cutting by the cutting blade 310, which is inefficient and prone to errors. In this application, a first inclined surface 302 is provided at both ends of the frame 300, and overlapping blocks 220 are fixedly installed at both ends of the moving plate 200. A second inclined surface 221 is provided on the upper side of the overlapping block 220, and the first inclined surface 302 and the second inclined surface 221 slide together. It also includes a clamping plate 210 fixedly installed at the inner end of the moving plate 200. When the first inclined surface 302 and the second inclined surface 221 slide relative to each other, the corresponding clamping plate 210 will clamp the material.

[0032] Specifically, in this application, when the drive shaft 330 controls the frame 300 to move toward the workbench 100, the corresponding frame 300 will move vertically downward along the limit plate 120. During this process, the second inclined surface 221 located on both sides of the lower end of the frame 300 will slide relative to the first inclined surface 302. During the sliding, the corresponding moving plate 200 and the clamping plate 210 fixedly installed at the inner end of the moving plate 200 will move inward synchronously and clamp the material located on the top surface of the workbench 100 to ensure that the material can be accurately fixed on the top surface of the workbench 100 and ensure the accurate cutting of the cutting blade 310.

[0033] As described above, the clamping plate 210 achieves material clamping in the lateral direction. Correspondingly, the position of the material also needs to be adjusted in the other direction. Therefore, in this application, the clamping plate 210 is elastically connected to the mounting plate on the top surface of the worktable 100 by a spring 211, and the moving plate 200 slides in cooperation with the slide groove 101 opened on the top surface of the worktable 100. It also includes a bladder 230 disposed in the slide groove 101, the bladder 230 being filled with inert gas. When the moving plate 200 slides in the slide groove 101, the moving plate 200 will compress the bladder 230; and two cavities 102 opened inside the worktable 100, the bladder 230 being kept in communication with the cavity 102 by a connecting groove 103, and a rubber strip 110 disposed on the upper side of the cavity 102 and located on the top surface of the worktable 100. Specifically, when the two clamping plates 210 move toward each other, the corresponding capsule 230 is compressed. Combined with the connection between the capsule 230 and the cavity 102 via the connecting groove 103, the gas inside the capsule 230 enters the cavity 102 and causes the rubber strip 110 to expand upward. During this process, the material at the top of the workbench 100 can move toward the center of the workbench 100, which is directly below the cutting blade 310, under the action of the rubber strip 110. It should be noted that during this process, the clamping plates 210 do not compress the material. At this time, the material can be stably adjusted in the longitudinal direction. With the subsequent clamping action of the clamping plates 210, the material can be accurately positioned.

[0034] Furthermore, multiple air vents 111 are linearly and equally spaced on the rubber strip 110, and valves are installed inside the air vents 111. In the horizontal direction, the cutting blade 310 is located between the middle of two rubber strips 110, and the frame 300 slides in cooperation with the limiting plate 120 fixedly installed on the top surface of the workbench 100. Multiple air vents 111 are provided on the corresponding rubber strips 110, and valves are provided on the air vents 111. When the air pressure in the cavity 102 increases to a certain pressure, the gas in the corresponding cavity 102 will overflow from the air vents 111 and be blown toward the position of the material to assist in the adjustment of the material's position and to treat the dust adhering to the outer wall of the material.

[0035] Furthermore, this application also includes symmetrical clearance grooves 301 formed on the top surface of the frame 300, and contact plates 320 fixedly installed on the frame 300. The inner wall of the clearance grooves 301 slides in engagement with the outer wall of the overlapping block 220. It also includes an arc-shaped frame 400 movably connected to the frame 300, which slides in engagement with a drive shaft 330 fixedly installed on the frame 300, and the lower end of the arc-shaped frame 400 is at the same horizontal plane as the bottom surface of the cutting blade 310. After the cutting blade 310 cuts the material, the drive shaft 330 needs to move upward. At this time, the overlapping block 220 will be in the clearance groove 301. After the cutting is completed, the outer wall of the overlapping block 220 will contact the outer wall of the contact plate 320. In this application, the contact plate 320 acts as a trigger switch. On the one hand, it can stop the frame 300, which was originally moving downward, from moving downward. On the other hand, after the cutting blade 310 has finished cutting, the scraps remaining at the edge of the material can be removed by the arc frame 400, which is movably connected to the frame 300, moving downward. This causes the arc frame 400 to slide relative to the frame 300, removing the scraps adhering to the edge of the cutting blade 310.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
