Description

Technical Field

[0001] The utility model relates to the field of cutting machine equipment, in particular to a high-precision cutting machine. Background Art

[0002] In the furniture industry, cutting machines are used to accurately and efficiently cut various materials such as metal, wood, stone, glass, etc. to meet the various shapes and sizes required in the furniture manufacturing process.

[0003] The cutting machine has a cutting platform with a cutting groove. The material to be cut is placed on the cutting platform. The saw blade passes through the cutting groove to cut the material to be cut placed on the cutting platform. During the cutting process, the edge of the cutting groove will be touched and worn by the saw blade. After long-term use, the wear becomes more serious. The material to be cut contacts the worn edge of the cutting groove, which will affect the processing accuracy. For this reason, the cutting platform can be replaced, but the cost-effectiveness of replacing the cutting platform is low because of the high cost and short service life after replacement. Therefore, the industry generally does not replace the cutting platform, but only fixes a pad on the cutting platform. The pad has a through groove, which is aligned with the cutting groove of the cutting platform, and the edge of the through groove is aligned with the edge of the cutting groove of the cutting platform. When the material to be cut is placed on the pad, it will not contact the worn edge of the cutting groove. During the cutting process, the edge of the through groove of the pad will be touched and worn by the saw blade. When the wear becomes more serious, only the pad needs to be replaced, without replacing the high-cost cutting platform. Despite this, since the saw blade will still wear to the edge of the cutting groove of the cutting platform, it will still damage the life of the cutting platform. Summary of the invention

[0004] The utility model aims to provide a high-precision cutting machine, the edges of the cutting grooves of the cutting platform are not easily worn, and the cutting platform has a long service life.

[0005] To achieve the above purpose, the utility model provides a high-precision cutting machine, including a cutting platform, a cutting groove is formed on the cutting platform, a pad is laid on the cutting platform, the pad blocks one side of the cutting groove and covers a part of the notch of the cutting groove.

[0006] Preferably, a cutting blade is included, and the cutting blade passes through the cutting groove to cut the object to be cut placed on the backing plate.

[0008] Preferably, the ends of the two cutting grooves are connected to form a V shape.

[0009] Preferably, there are two cutting blades, each of which passes through the two cutting grooves.

[0021] The present invention is further described in detail below in conjunction with specific implementation methods.

[0022] Cutting machine Figure 1 As shown, it includes a long strip cutting platform 3, and two cutting grooves 4 are opened on the cutting platform 3; Figure 2 As shown, the two cutting grooves 4 are perpendicular to each other, the ends 42 are connected, and the beginnings 41 are respectively opened to the edge of the beginning side 31 of the cutting platform 3. The two cutting grooves 4 divide the cutting platform 3 into three areas A, B, and C. The end side 32 of the cutting platform 3 extends upwardly from the limiting wall 9 (see Figure 2 , Figure 5 ), the orthographic projection of the limiting wall 9 on the cutting platform 3 to the end of the cutting groove 4. Figure 1 As shown, two pads 5 are laid on the two end areas A and C of the cutting platform 3, respectively. Each pad 5 blocks the groove edge 33 of the cutting groove 4 adjacent to the laid area, and blocks a part of the notch of the cutting groove 4. The end side of the pad 5 abuts against the limiting wall 9, and the cutting machine is provided with a tightening device 1 to tighten the pad 5 against the limiting wall 9. Figure 4 As shown, a pad 8 made of polytetrafluoroethylene is fixed to the second area B of the cutting platform 3 between the two cutting grooves 4 by screws (omitted in the figure). The pad surface of the pad 8 is at the same height as the pad 5, supporting the part of the object to be cut located in this area. Figure 3 As shown, the cutting machine is provided with two cutting blades 2, which are specifically saw blades (or blades), and a pressure beam 6, which is against the cutting blades 2 to press and fix the object to be cut. In this embodiment, the object to be cut is a plate, which is placed on the backing plate 5, and the cutting end side of the plate is against the limiting wall 9. Then the cutting machine is started, and the two cutting blades 2 pass through the two cutting grooves 4 respectively, and cut along the cutting grooves 4 from the beginning to the end, and cut the plate into three pieces corresponding to areas A, B, and C. During the cutting process, since the backing plate 5 blocks the groove edge 33 of the cutting groove 4 adjacent to the paved area, the groove edge 33 of the cutting platform 3 is not easily worn.

[0023] The tightening device 1 is specifically as follows Figure 5As shown: the clamping device 1 includes a fixing seat 10 fixed to the back of the limiting wall 9 by screws 7, the bottom of the fixing seat 10 is located below the cutting platform 3, and an axially movable connecting rod 13 extends toward the starting side 31 of the cutting platform 3, the tail of the connecting rod 13 extends to cross the starting side 31 of the cutting platform 3 and is fixed with a force block 11 extending upward to the height of the pad 5; the starting side 51 of the pad 5 does not reach the starting side 31 of the cutting platform 3, and the force block 11 protrudes toward the pad 5 with a force applying portion 12, which is placed on the cutting platform 3. The root of the connecting rod 13 passes through the bottom of the fixing seat 10, and the root of the connecting rod 13 is provided with a thread 15 and a corresponding nut 14 as a fastener; tighten the nut 14, and the connecting rod 13 moves along the cutting direction ( Figure 5 The axial movement (in the direction indicated by the arrow) drives the force-applying part 12 to press the pad 5 against the limiting wall 9. Figure 1 As shown, since the pad 5 blocks the groove edge 33 of the cutting groove 4 adjacent to the paved area, after the cutting machine is used for a period of time, the side of the pad 5 that blocks the groove edge 33 will be touched and worn by the cutting blade 2. For this reason, the user needs to loosen the nut 14, so that the connecting rod 13 moves axially against the cutting direction to drive the force-applying part 12 away from the pad 5, so that the pad 5 is not pressed against the limiting wall 9, and then the user operates the pad 5 to move toward the cutting blade 2, so that the pad 5 enters the cutting range, and then operates the cutting machine to cut off the worn sawing path of the pad 5, and continue to let the pad 5 move horizontally until the pad 5 blocks the groove edge 33 of the cutting groove 4 again for protection, covering a part of the notch of the cutting groove 4, so that the groove edge of the cutting groove 4 of the cutting platform 3 can be kept from being worn. Then the user tightens the nut 14 of the tightening device 1, and the tightening device 1 tightens the pad 5 against the limiting wall 9 again.

[0024] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
