Description

Technical Field

[0001] The invention relates to a cutting method and a saw blade slitting machine. Background Art

[0002] Composite materials are new materials created by optimizing the combination of components with different properties using advanced material preparation technologies. Generally, composite materials must meet the following criteria. Composite matrix materials are categorized as metals and non-metals. Non-metallic matrices primarily include synthetic resins, rubber, ceramics, graphite, and carbon. Reinforcement materials primarily include glass fiber, carbon fiber, boron fiber, aramid fiber, silicon carbide fiber, asbestos fiber, whiskers, and metals.

[0003] For traditional board materials, the utility model patent with authorization announcement number "CN 206286640U" achieves cutting through a lifting and rotating saw blade; however, for composite materials, due to their superior performance, the amount of cutting at one time is too large, which can easily lead to problems with cutting accuracy. Summary of the Invention

[0004] The object of the present invention is to provide a cutting method for cutting composite materials with high structural strength.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a cutting method comprising the following steps:

[0006] Step 1: The cutting platform is provided with a plurality of cutting grooves along the feeding direction of the plate, wherein each of the cutting grooves is located on the same straight line and each of the cutting grooves gradually becomes longer along the feeding direction;

[0007] Step 2: A retractable rotary saw blade is provided at the bottom of each cutting groove, wherein the size of the rotary saw blade corresponds to the length of the cutting groove;

[0008] Step 3: The plate is fed, and the rotary saw blade rises and rotates;

[0009] Step 4: A lifting roller is provided between adjacent cutting grooves, and the plate is pressed onto the cutting platform by the rotating roller;

[0010] Step 5: When the plate is conveyed and the cutting is completed, the saw blade stops rotating, lowers the saw blade below the cutting platform, and rotates the roller to lift it.

[0011] By adopting the above technical solution, when cutting composite materials with high structural strength and excellent performance, the cutting is not done in one go. Instead, the cutting amount is converted into multiple cuts, reducing the cutting amount each time. That is, the negative factors such as the reaction force and vibration generated by each cut are reduced, thereby improving the cutting accuracy. At the same time, it also solves the problems of safety and support strength.

[0012] Preferably, the number of the cutting grooves is two.

[0013] By adopting the above technical solution, a more general cutting method can increase the number of cutting grooves when the cutting difficulty increases.

[0014] Preferably, the rotary saw blade can be moved in the width direction via a guide rail.

[0015] By adopting the above technical solution, the cutting position can be adjusted.

[0016] Another object of the present invention is to provide a saw blade slitting machine using this method.

[0017] Another technical purpose of the present invention is achieved through the following technical solutions: A saw blade longitudinal cutting machine, comprising a cutting platform, wherein the upper surface of the cutting platform is provided with a first cutting groove and a second cutting groove, the first cutting groove and the second cutting groove are arranged through the cutting platform, the first cutting groove and the second cutting groove are in the same straight line, the length of the first cutting groove is greater than the length of the second cutting groove, saw blades are respectively provided at the bottom of the first cutting groove and the second cutting groove, a cutting part is provided at the bottom of the cutting platform, the cutting part corresponds one-to-one to the saw blade, and the cutting part includes a first driving part for driving the saw blade to move toward the first cutting groove or the second cutting groove and a second driving part for driving the saw blade to rotate.

[0018] By adopting the above technical solution, when further cutting is required, the second driving unit drives the saw blade to rotate, and then, driven by the first driving unit, the two saw blades move toward the first cutting groove and the second cutting groove respectively, and protrude from the surface of the cutting platform. When the plate passes, the shorter saw blade in the first cutting groove first cuts a certain thickness, and then the longer saw blade in the second cutting groove cuts a greater thickness. Multiple cuttings are performed during the movement of the plate, thereby improving the cutting accuracy.

[0019] Preferably, a movable frame is provided at the bottom of the cutting platform, the cutting part includes a rotating seat, the rotating seat is hinged to the movable frame, the first driving part is a cylinder, the bottom of the cylinder is hinged to the movable frame, the piston rod of the cylinder is hinged to the rotating seat, a rotating shaft is provided above the rotating seat, the second driving part is a second motor provided below the rotating seat, one end of the rotating shaft and the shaft of the second motor are provided with synchronous pulleys, and the other end of the rotating shaft is provided for the saw blade to be set.

[0020] By adopting the above technical solution, the cylinder causes the rotating seat to rotate on the movable frame during the extension and retraction process, thereby causing the saw blade to protrude from the surface of the cutting platform or be located below the cutting platform. At the same time, the second motor rotates, and the saw blade is driven by the synchronous pulley and the synchronous belt to rotate to cut the plate.

[0021] Preferably, the hinge point of the piston rod of the cylinder and the rotation axis are respectively located on both sides of the rotating seat, and the hinge point of the rotating seat and the movable frame is located between the cylinder and the rotation axis.

[0022] By adopting the above technical solution, the piston rod can control the large rotation of the rotating seat through a shorter stroke.

[0023] Preferably, the cutting portion at the bottom of the first cutting groove and the cutting portion at the bottom of the second cutting groove are mirror-imaged with the movable frame as the center.

[0024] By adopting the above technical solution, the structure is simplified and the space occupied by the cutting part is reduced.

[0025] Preferably, the movable frame is provided with a vertical plate located between the two cutting parts, and the vertical plate is provided with a bolt with adjustable length, and one end of the bolt is located within the rotation range of the rotating seat.

[0026] By adopting the above technical solution, the maximum rotation range of the saw blade is limited, thereby preventing the rotating saw blade from damaging the cutting groove during the cutting process.

[0027] Preferably, the rotating seat includes a first rotating seat and a second rotating seat, one end of the first rotating seat, one end of the second rotating seat and the fixed seat are hinged on the same axis, the other end of the first rotating seat and the other end of the second rotating seat are provided with an adjustment device, the rotating shaft is rotatably connected to the top of the first rotating seat, and the second motor is arranged at the bottom of the second rotating seat.

[0028] By adopting the above technical solution, the adjustment device plays a role in adjusting the distance between the second motor and the rotating shaft, thereby controlling the tension of the synchronous belt, and at the same time fixing the first rotating seat and the second rotating seat into one.

[0029] Preferably, the adjustment device includes a threaded rod hinged on the first rotating seat, and the second rotating seat is provided with a through hole that cooperates with the threaded rod, and fixing nuts are provided on both sides of the through hole.

[0030] In summary, the present invention has the following beneficial effects: when cutting composite materials with high structural strength and excellent performance, it is not formed by one cutting, but the cutting amount of one time is converted into the amount of multiple cuttings, reducing the cutting amount each time, that is, reducing the reaction force, vibration and other negative factors generated by each cutting, and improving the cutting accuracy; at the same time, it also solves the safety problems and support strength problems.
