Description

Technical Field

[0001] The present invention relates to a cutting tool, and more particularly to a cutting saw blade and a cutting device. Background Art

[0002] At present, the saw blades used for cutting solid wood and aluminum alloy are very different in blade angle design. For different materials to be cut, the selected blade heads are often inconsistent. The use of a positive and negative blade head arrangement can effectively solve the problem of different blade shapes and angles, so that different blade heads can work normally in their respective working rotation directions; for different blade head designs, their sizes and cutting angles are inconsistent, and there may be problems with empty cutting at the cutting point of the blade head. Smaller blade heads either need to be designed with a higher mounting part, or it is difficult to ensure the cutting effect. In addition, the forward and reverse blade head cutting method is to raise the angle of the top of the blade head and cut with the protruding part of the front end of the blade head, while the front end is designed to be a straight structure, which is more unfavorable for cutting and has greater cutting resistance.

[0003] For example, the Chinese patent announcement number is CN115488427A, the announcement date is December 20, 2022, and the invention name is a forward and reverse circular saw blade, comprising: a disc-shaped base with a center hole, multiple groups of forward and reverse cutter heads joined on the outer circumference of the base; a chip groove is formed between two adjacent groups of forward and reverse cutter heads; wherein, mutually connected silencer grooves and silencer holes are opened at the bottom of some chip grooves; and multiple groups of heat dissipation holes are arranged on the base; the heat dissipation holes and silencer holes are respectively staggered in the circumferential and radial directions of the base. This forward and reverse dual-purpose circular saw blade can realize the forward and reverse processing of the circular saw blade, a silencer groove is arranged at the bottom of the chip groove, a silencer hole is opened at the bottom of the silencer groove, and a heat dissipation hole is arranged on the base, so as to realize the silencing and heat dissipation functions of the circular saw blade during operation. In the design of this scheme, the top height designs of the two forward and reverse rotating cutter heads are not consistent. One of them has a larger inclination angle, while the other cutter head has a smaller inclination angle. This can easily lead to empty cutting when the smaller cutter head is working. In addition, the front end face is basically in a vertical state, which increases the contact area with the cut material, increases the cutting resistance, and causes poor cutting effect. Summary of the invention

[0004] The present invention overcomes the problem of poor cutting effect of existing cutting tools and provides a cutting saw blade. The present invention ensures the cutting effect of the cutting saw blade and avoids empty cutting by reasonably arranging and designing the forward and reverse blade angles and sizes on the tool. Another object of the present invention is to provide a cutting device, which can realize continuous cutting of different plates and achieve the effect of different alternating stacking of different plates.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a cutting saw blade, comprising a saw blade body, a cutter head assembly is arranged at the outer diameter of the saw blade body, the cutter head assembly comprises a first cutter head and a second cutter head, the radial outer end points of the first cutter head and the second cutter head are located on the same circle, the first cutter head and the second cutter head comprise a first cutting surface and a second cutting surface, the first cutting surface and the radius where the outer end point of the first cutter head is located form a first cutting angle, the second cutting surface and the tangent where the outer end point of the first cutter head is located form a second cutting angle, and the angle range of the first cutting angle and the second cutting angle is 10° to 15°. In this solution, the radial outer end points of the first cutter head and the second cutter head are arranged on the same circle, so that when the saw blade rotates, the first cutter head and the second cutter head are on the same cutting radius, thereby ensuring that the corresponding cutter heads in the working direction cut normally and avoiding the phenomenon of empty cutting. In addition, the first cutting angle is the front side angle of the first cutter head and the second cutter head in the working rotation direction, and the second cutting angle is the rear side angle of the first cutter head and the second cutter head in the working shaking direction, and the cutting effect of the first cutter head and the second cutter head is improved by designing the first cutting angle and the second cutting angle to be inclined.

[0006] Preferably, the first cutting surface is arranged along the radial direction of the saw blade body, the second cutting surface is arranged along the circumferential direction of the saw blade body, and the first cutting surface and the second cutting surface are arranged at an acute angle. The first cutting surface and the second cutting surface are arranged at an acute angle, which ensures the cutting effect of the cutter head. The front end surface of the cutter head can reduce the contact area between the cutter head and the cut material, thereby improving the cutting force, while the rear end surface of the cutter head can reduce the contact connection between the cutter head and the cutting position, reduce cutting friction, and thus improve the cutting effect of the tool.

[0007] Preferably, the cutter head assembly further comprises a plurality of cutter head mounting parts distributed circumferentially, and the first cutter head and the second cutter head are respectively arranged on both sides of the cutter head mounting part. The first cutter head and the second cutter head are respectively installed on both sides of the cutter head mounting part, and are respectively used for forward and reverse cutting, so as to realize cutting of various materials.

[0008] Preferably, the cutter head mounting parts are spaced apart and form notches on the saw blade body, which can remove debris generated by the cutter cutting, reduce friction during the cutter cutting process, and improve the cutting effect.

[0009] Preferably, the bottom of the notch is connected to the bottom of the cutter head mounting portion by an arc transition, and the bottom of the notch and the bottom of the cutter head mounting portion form an inner concave portion that gradually increases radially inward. The arc design of the bottom of the notch and the bottom of the cutter head mounting portion can reduce the stress at the notch, and the inner concave portion at the bottom of the notch increases the space at the bottom of the notch, which can improve the chip removal effect on the one hand, and reduce the friction between the two side end surfaces of the saw blade body and the cut material on the other hand, reduce the heat generated by friction, and also have a noise reduction effect.

[0010] Preferably, a plurality of the notches are provided with a muffler line, and the muffler line extends radially from the notch toward the center of the saw blade body to form a curled shape. The muffler line is directly connected to the bottom of the notch, and a plurality of mufflers are arranged, and are arranged on both sides of the saw blade body, so that the noise generated by the tool when working can be reduced, and a good muffler effect can be achieved.

[0011] Preferably, the second cutting surface on the first cutter head and the second cutting surface of the second cutter head are connected to the cutter head mounting portion by arc surfaces. The second cutting surfaces of the first cutter head and the second cutter head are in a non-working state when rotating in opposite directions, so that the second cutting surfaces of the first cutter head and the second cutter head and the cut material are likely to generate a large reverse friction or resistance, which is likely to cause the cutter head to fall off. The design of the arc surface can reduce the reverse force on the first cutter head and the second cutter head, thereby protecting the cutter heads.

[0012] A cutting device includes the above-mentioned cutting saw blade, and also includes a cutting tool and a control component. The cutting saw blade and the control component are arranged on both sides of the cutting tool. The cutting tool is provided with a cutting track, and the cutting saw blade reciprocates along the cutting track. The cutting tool is used to install the cutting saw blade, and the control component can control the cutting saw blade to move on the cutting track on the cutting tool to achieve the effect of reciprocating cutting. The reciprocating motion of the cutting saw blade corresponds to its two cutting modes of forward rotation and reverse rotation, respectively, so that two types of plates can be continuously and alternately cut.

[0013] Preferably, the control assembly includes a first rod group and a second rod group, the first rod group and the second rod group are arranged vertically and slidably connected relative to each other, and the cutting saw blade is arranged on the first rod group and the second rod group. The first rod group and the second rod group respectively control the lateral movement and longitudinal movement of the cutting saw blade to ensure the movement trajectory and positioning effect of the cutting saw blade.

[0014] Preferably, the cutting track is U-shaped. The cutting track is designed in a U-shape, so that after the cutter is finished cutting, a lifting operation can be performed, so that the next plate can enter the cutting area of ​​the cutting tool to achieve continuous cutting.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) This solution ensures the cutting effect of the cutting saw blade and avoids empty cutting by reasonably arranging and designing the forward and reverse blade angles and sizes on the tool; (2) It can realize continuous cutting of different plates and achieve the effect of alternating stacking of different plates, thereby improving the cutting efficiency of the plates; (3) The structure is further simplified, the noise reduction effect is further reduced, and the friction and heat generated during the cutting process are reduced.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0024] Example 1: Figures 1 to 4A cutting saw blade shown includes a saw blade body 1, which is circular in shape as a whole. A plurality of cutter head mounting parts 10 are arranged outside the saw blade body 1. The cutter head mounting parts 10 are in a convex state on the outer diameter of the saw blade body 1. Specifically, there are 24 groups of cutter head mounting parts 10, which are evenly, spaced and annularly distributed at the outer edge of the saw blade body 1, so that the interval angle between each group of cutter head mounting parts 10 is 15°. The cutter head mounting part 10 is an integral structure with the saw blade body 1. A first step part 10.1 and a second step part 10.2 are arranged on the cutter head mounting part 10. The first step part 10.1 and the second step part 10.2 are symmetrically arranged at the middle parts of the two sides of the cutter head mounting part 10, respectively. A cutter head assembly 2 is installed on the first step 10.1 and the second step 10.2. Specifically, a first cutter head 3 and a second cutter head 4 are installed on the first step part 10.1 and the second step part 10.2, respectively. The first blade head 3 and the second blade head 4 are fixed to the first step 10.1 and the second step 10.2 respectively by welding.

[0025] Since there are multiple cutter head mounting parts 10, the first step part 10.1 is a structure on the same side of all cutter head mounting parts 10, and the second step part 10.2 is a structure on the other side of all cutter head mounting parts 10, so that after the first cutter heads 3 and the second cutter heads 4 are installed, all the first cutter heads 3 will work at the same time, all the second cutter heads 4 will work at the same time, and the working movements of the first cutter heads 3 and the second cutter heads 4 are separated. That is to say, when the saw blade body 1 rotates in the counterclockwise direction, all the first cutter heads 3 enter the working state, and when the saw blade body 1 rotates in the clockwise direction, all the second cutter heads 4 enter the working state, such as Figure 2 , Figure 3 and Figure 4 In the orientation shown, the cutter head on the left side of the cutter head mounting portion 10 is the first cutter head 3, and the cutter head on the right side of the cutter head mounting portion 10 is the second cutter head 4. The first cutter head 3 and the second cutter head 4 both include a first cutting surface 6 and a second cutting surface 7. The first cutting surface 6 is the front end surface of the first cutter head 3 and the second cutter head 4 along their respective working rotation directions, and the second cutting surface 7 is the rear end surface of the first cutter head 3 and the second cutter head 4 along their respective working rotation directions. When the saw blade body 1 rotates, the first cutting surface 6 is extruded along the circumferential direction of the saw blade body 1 with the plate being cut, so as to achieve the purpose of cutting. The second cutting surface 7 is extruded along the radial direction of the saw blade body 1 with the plate being cut. In the cutting process of the tool, the first cutting surface 6 plays a major role in material cutting, and the second cutting surface 7 mainly achieves the effect of reducing friction.

[0026] In this embodiment, the first cutting surface 6 is more inclined to the radial direction of the saw blade body 1, and the second cutting surface 7 is more inclined to the circumferential direction of the saw blade body 1. The first cutting surface 6 and the second cutting surface 7 form an acute angle, so that the first cutting surface 6 and the second cutting surface 7 of the cutter head assembly 2 (the first cutter head 3 and the second cutter head 4) are inclined toward the position of the tool mounting portion 10, ensuring that the working part of the cutter head is sharp enough to generate a large cutting force to cut the plate. Specifically, the outermost end points of all the first cutter heads 3 from the saw blade body 1 and the outermost end points of all the second cutter heads 4 from the saw blade body 1 are located on the same circle, such as Figure 2 As shown, the circle is defined here as the outer diameter circle 5, the angle between the radius plane formed between the outermost end point of the first cutter head 3 and the axis of the saw blade body 1 and the first cutting surface 6 is the first cutting angle 8, the angle between the cutting plane where the intersection of the outermost end point of the first cutter head 3 and the outer diameter circle 5 is located and the second cutting surface 7 is the second cutting angle 9, and the range of the first cutting angle 8 and the second cutting angle 9 is between 10° and 15°. In this way, when the first cutter head 3 contacts the material to be cut, only a part of the cutting surface between the first cutting surface 6 and the material to be cut will contact the material to be cut, thereby reducing the contact area between the first cutting surface 6 and the material to be cut and increasing the pressure during cutting, which makes it easier for the first cutter head 3 to cut the material to be cut apart; in addition, between the second cutting surface 7 and the arc-shaped cutting groove formed by cutting, only the intersection of the first cutting surface 6 and the second cutting surface 7 will produce a larger radial pressure along the saw blade body 1, and the extrusion pressure generated on the rest of the second cutting surface 7 is smaller, so that the extrusion friction generated between the second cutting surface 7 and the cut arc-shaped cutting groove is reduced as a whole, which is beneficial to reducing the noise generated by the tool during cutting and reducing the heat generated by the tool. The design of the second cutter head 4 is the same as that of the first cutter head 3. Therefore, the angle range of the first cutting angle 8 and the second cutting angle 9 of the second cutter head 4 is also designed to be between 10° and 15°, that is, the first cutting angle 8 and the second cutting angle 9 do not exceed the interval angle between the cutter head mounting parts 10. If the angles of the first cutting angle 8 and the second cutting angle 9 are too large, the volume of the intersection of the first cutting surface 6 and the second cutting surface 7 will be reduced, resulting in a very sharp structure. Although it can further improve the cutting effect, it is easy to damage the cutter head and the service life is very short. It should be noted that Figure 3 and Figure 4 The dotted lines in the figure are auxiliary lines used to indicate angles or outer diameter circles.

[0027] Since the cutter head mounting parts 10 are arranged at intervals, slots 11 can be formed between the cutter head mounting parts 10. The slots 11 can timely discharge the chips generated by the cutting of the first cutter head 3 and the second cutter head 4, and prevent the chips from staying in the cutter heads and the cut material, thereby reducing the friction generated by the first cutter head 3 and the second cutter head 4 during the cutting process, and also reducing noise and heat. Inner recesses 12 are also provided on both sides of the bottom of the slot 11, that is, the bottom of the slot 11 extends along the direction of the cutter head mounting parts 10 on both sides, so that the slot 11 gradually increases inward along the radial direction of the saw blade body 1, that is, the hollow part of the slot 11 on the side facing the center of the saw blade body 1 is larger, so that on the one hand, the overall volume of the slot 11 is increased, and on the other hand, the slot 11 forms a muffler hole to a certain extent, that is, the muffler hole originally located inside the saw blade body 1 is integrated into the position of the slot 11, which not only reduces the difficulty of the processing technology of the saw blade body 1, but also makes the chip removal effect of the slot 11 better, and the effect of cooling and noise reduction is significantly improved. And because the main working parts of the cutting saw blade are close to the position of the cutter head, this design is closer to the working position of the cutter and the design is more reasonable.

[0028] It should also be noted that the arc design is used for transition between the recessed portions 12 on both sides of the notch 11 and the cutter head mounting portion 10 , which can eliminate stress concentration between the notch 11 and the recessed portions 12 and ensure the strength and service life of the saw blade body 1 .

[0029] Example 2: Figures 1 to 4 A cutting saw blade shown includes a saw blade body 1, which is circular in shape as a whole. A plurality of cutter head mounting parts 10 are arranged outside the saw blade body 1. The cutter head mounting parts 10 are in a convex state on the outer diameter of the saw blade body 1. Specifically, there are 24 groups of cutter head mounting parts 10, which are evenly, spaced and annularly distributed at the outer edge of the saw blade body 1, so that the interval angle between each group of cutter head mounting parts 10 is 15°. The cutter head mounting part 10 is an integral structure with the saw blade body 1. A first step part 10.1 and a second step part 10.2 are arranged on the cutter head mounting part 10. The first step part 10.1 and the second step part 10.2 are symmetrically arranged at the middle parts of the two sides of the cutter head mounting part 10, respectively. A cutter head assembly 2 is installed on the first step 10.1 and the second step 10.2. Specifically, a first cutter head 3 and a second cutter head 4 are installed on the first step part 10.1 and the second step part 10.2, respectively. The first blade head 3 and the second blade head 4 are fixed to the first step 10.1 and the second step 10.2 respectively by welding.

[0030] Since there are multiple cutter head mounting parts 10, the first step part 10.1 is a structure on the same side of all cutter head mounting parts 10, and the second step part 10.2 is a structure on the other side of all cutter head mounting parts 10, so that after the first cutter heads 3 and the second cutter heads 4 are installed, all the first cutter heads 3 will work at the same time, all the second cutter heads 4 will work at the same time, and the working movements of the first cutter heads 3 and the second cutter heads 4 are separated. That is to say, when the saw blade body 1 rotates in the counterclockwise direction, all the first cutter heads 3 enter the working state, and when the saw blade body 1 rotates in the clockwise direction, all the second cutter heads 4 enter the working state, such as Figure 2 , Figure 3 and Figure 4 In the orientation shown, the cutter head on the left side of the cutter head mounting portion 10 is the first cutter head 3, and the cutter head on the right side of the cutter head mounting portion 10 is the second cutter head 4. The first cutter head 3 and the second cutter head 4 both include a first cutting surface 6 and a second cutting surface 7. The first cutting surface 6 is the front end surface of the first cutter head 3 and the second cutter head 4 along their respective working rotation directions, and the second cutting surface 7 is the rear end surface of the first cutter head 3 and the second cutter head 4 along their respective working rotation directions. When the saw blade body 1 rotates, the first cutting surface 6 is extruded along the circumferential direction of the saw blade body 1 with the plate being cut, so as to achieve the purpose of cutting. The second cutting surface 7 is extruded along the radial direction of the saw blade body 1 with the plate being cut. In the cutting process of the tool, the first cutting surface 6 plays a major role in material cutting, and the second cutting surface 7 mainly achieves the effect of reducing friction.

[0031] In this embodiment, the first cutting surface 6 is more inclined to the radial direction of the saw blade body 1, and the second cutting surface 7 is more inclined to the circumferential direction of the saw blade body 1. The first cutting surface 6 and the second cutting surface 7 form an acute angle, so that the first cutting surface 6 and the second cutting surface 7 of the cutter head assembly 2 (the first cutter head 3 and the second cutter head 4) are inclined toward the position of the tool mounting portion 10, ensuring that the working part of the cutter head is sharp enough to generate a large cutting force to cut the plate. Specifically, the outermost end points of all the first cutter heads 3 from the saw blade body 1 and the outermost end points of all the second cutter heads 4 from the saw blade body 1 are located on the same circle, such as Figure 2As shown, the circle is defined here as the outer diameter circle 5, the angle between the radius plane formed between the outermost end point of the first cutter head 3 and the axis of the saw blade body 1 and the first cutting surface 6 is the first cutting angle 8, the angle between the cutting plane where the intersection of the outermost end point of the first cutter head 3 and the outer diameter circle 5 is located and the second cutting surface 7 is the second cutting angle 9, and the range of the first cutting angle 8 and the second cutting angle 9 is between 10° and 15°. In this way, when the first cutter head 3 contacts the material to be cut, only a part of the cutting surface between the first cutting surface 6 and the material to be cut will contact the material to be cut, thereby reducing the contact area between the first cutting surface 6 and the material to be cut and increasing the pressure during cutting, which makes it easier for the first cutter head 3 to cut the material to be cut apart; in addition, between the second cutting surface 7 and the arc-shaped cutting groove formed by cutting, only the intersection of the first cutting surface 6 and the second cutting surface 7 will produce a larger radial pressure along the saw blade body 1, and the extrusion pressure generated on the rest of the second cutting surface 7 is smaller, so that the extrusion friction generated between the second cutting surface 7 and the cut arc-shaped cutting groove is reduced as a whole, which is beneficial to reducing the noise generated by the tool during cutting and reducing the heat generated by the tool. The design of the second cutter head 4 is the same as that of the first cutter head 3. Therefore, the angle range of the first cutting angle 8 and the second cutting angle 9 of the second cutter head 4 is also designed to be between 10° and 15°, that is, the first cutting angle 8 and the second cutting angle 9 do not exceed the interval angle between the cutter head mounting parts 10; if the angles of the first cutting angle 8 and the second cutting angle 9 are too large, the volume of the intersection of the first cutting surface 6 and the second cutting surface 7 is reduced, resulting in a very sharp structure. Although it can further improve the cutting effect, it is easy to damage the cutter head and the life is very short.

[0032] Since the cutter head mounting parts 10 are arranged at intervals, slots 11 can be formed between the cutter head mounting parts 10. The slots 11 can timely discharge the chips generated by the cutting of the first cutter head 3 and the second cutter head 4, and prevent the chips from staying in the cutter heads and the cut material, thereby reducing the friction generated by the first cutter head 3 and the second cutter head 4 during the cutting process, and also reducing noise and heat. Inner recesses 12 are also provided on both sides of the bottom of the slot 11, that is, the bottom of the slot 11 extends along the direction of the cutter head mounting parts 10 on both sides, so that the slot 11 gradually increases inward along the radial direction of the saw blade body 1, that is, the hollow part of the slot 11 on the side facing the center of the saw blade body 1 is larger, so that on the one hand, the overall volume of the slot 11 is increased, and on the other hand, the slot 11 forms a muffler hole to a certain extent, that is, the muffler hole originally located inside the saw blade body 1 is integrated into the position of the slot 11, which not only reduces the difficulty of the processing technology of the saw blade body 1, but also makes the chip removal effect of the slot 11 better, and the effect of cooling and noise reduction is significantly improved. And because the main working parts of the cutting saw blade are close to the position of the cutter head, this design is closer to the working position of the cutter and the design is more reasonable.

[0033] It should also be noted that the arc design is used for transition between the recessed portions 12 on both sides of the notch 11 and the cutter head mounting portion 10 , which can eliminate stress concentration between the notch 11 and the recessed portions 12 and ensure the strength and service life of the saw blade body 1 .

[0034] At the positions corresponding to some of the notches, silencer lines are also provided. The silencer lines are wire groove structures provided on the saw blade body. The silencer lines can reduce the noise generated by the saw blade body during the cutting process, and at the same time can enhance the surface strength of the saw blade body. The silencer lines extend from the middle of the notch toward the center of the saw blade body and curl to form a spiral ring. This allows the silencer lines to be closer to the location of the tool assembly, and can also increase the length of the silencer lines, improve the silencer effect, and enhance the structural strength of the saw blade body. In addition, the silencer lines are arranged on both sides of the saw blade body, and are evenly arranged along the ring of the saw blade body, such as Figure 1 or Figure 2 As shown, there are four groups of silencer lines on one side of the saw blade body, so there are eight groups of silencer lines on the two sides of the saw blade body.

[0035] In addition, in order to improve the cutting effect of the cutter head assembly, the first cutter head and the second cutter head are higher than the cutter head mounting part on the fixed surface of the first cutter head and the second cutter head with the cutter head mounting part, and the design of the second cutting angle makes the first cutter head and the second cutter head have a better cutting effect. However, on the contrary, when the first cutter head is cutting, the second cutter head cannot cut, and the back of the second cutter head (the fixed surface with the cutter head mounting part) is also subject to the reverse force of the material to be cut, which makes it easy for the back of the second cutter head protruding from the cutter head mounting part to fall off and separate from the cutter head mounting part. Therefore, it is necessary to design the back of the second cutter head (the fixed surface with the cutter head mounting part) and the part protruding from the cutter head mounting part into an arc-shaped structure, which can not only reduce the stress concentration on the back of the cutter head, but also reduce the back pressure on the second cutter head when the first cutter head is working, and prevent the risk of the second cutter head falling off. Similarly, the back of the first cutter head (the fixed surface with the cutter head mounting part) and the part protruding from the cutter head mounting part are designed into an arc-shaped structure.

[0036] Example 3: Figure 5 and Figure 6 Combined with Figures 1 to 4A cutting device is shown, comprising a cutting tool 14 and a control component 15 and a cutting saw blade in Example 1 or Example 2, a cutting table 17 is provided at the bottom of the cutting tool 14 and the control component 15, and the cutting table 17 can be used to place a plate 18 to be cut; a U-shaped cutting track 16 is provided on the cutting tool 14, and the cutting saw blade is slidably set on the cutting track 16 through a driving device (not shown in the figure) and can move back and forth along the U-shaped cutting track 16. When the cutting saw blade is at the top of one end of the U-shaped cutting track 16, the bottom of the cutting saw blade is higher than the height of the cutting table 17. In this way, the plate 18 can be transported onto the cutting table 17 and correspond to the position of the cutting tool 14. Then the driving device is started to make the cutting saw blade rotate forward or reversely. At the same time, the cutting saw blade is controlled by the control component 15 to move along the shape of the cutting track 16. In this way, the cutting saw blade will move downward from the initial position and contact the plate 18 to start cutting. When the cutting saw blade drops to the bottom position, the cutting saw blade can cut through the plate 18, and then move linearly along the bottom of the cutting track 16 to cut the entire plate 18. Finally, it is lifted to the top of the other side of the U-shaped cutting track 16, and the cutting saw blade is separated from the position of the cutting table 17. The cut plate 18 is sent away by the feeding device, and the plate 18 to be cut continues to be conveyed to the cutting table through the feeding device. Then the cutting saw blade is reversed and returns along the cutting track 16 to further cut the plate 18.

[0037] Since the first cutter head 3 and the second cutter head 4 on the cutting saw blade are two cutter heads for cutting different plates 18, this solution can be applicable to the situation where different types of plates 18 are stacked alternately; of course, the first cutter head 3 and the second cutter head 4 can also be designed to be the same cutter head, so that the first cutter head 3 and the second cutter head 4 can actually cut the same plate 18, thereby improving the cutting efficiency of the same type of plate 18 and avoiding wasting cutting time on the return stroke.

[0038] Specifically, the control assembly 15 includes a first rod group 15.1 and a second rod group 15.2, which are slidably arranged on the back of the cutting tool 14, and the first rod group 15.1 and the second rod group 15.2 can also slide horizontally and vertically, so a sliding track is arranged between the first rod group 15.1 and the second rod group 15.2, and the cutting saw blade is slidably arranged on the sliding tracks of the first rod group 15.1 and the second rod group 15.2 using a fixed seat, so that when the first rod group 15.1 and the second rod group 15.2 are displaced horizontally and vertically, they can drive the cutting saw blade to also be displaced horizontally and vertically, so that the cutting saw blade adapts to the track of the cutting track 16 on the cutting tool 14. Among them, the first rod group 15.1 is a rod member arranged horizontally, which can control the cutting saw blade to move in the vertical direction, and the second rod group 15.2 is a rod member arranged vertically, which can control the cutting saw blade to move in the horizontal direction.
