Description

Technical Field

[0001] This invention relates to the field of wood formwork cutting, specifically to a cutting device and method for multi-layer building formwork. Background Technology

[0002] Construction formwork is a temporary support used in concrete structure construction. Its core function is to fix the shape, size and position of the uncured concrete during the concrete pouring process, bear the self-weight of the concrete, construction loads and other external forces, until the concrete hardens and is removed and reused. Common materials include wood, steel, plastic and composite materials, and different materials are suitable for different construction scenarios.

[0003] With the increasing demand for building formwork and prefabricated structure processing, in order to improve production efficiency and reduce the processing cost per unit product, the formwork processing process generally adopts a multi-layer stacking and simultaneous cutting method. Multiple formwork pieces can be cut synchronously in one cut, and multiple workpieces can be processed in the same work cycle, thereby significantly improving cutting efficiency.

[0004] In practical applications, while multi-layer template stacking and cutting improves processing efficiency, it also brings new problems. The inventors found that in the existing multi-layer template cutting process, the saw blade starts cutting into the template from one end and gradually advances towards the other end along the length. When the saw blade cuts to near the end, only weak, uncut connecting parts, i.e., residual ribs, remain between the template layers. Under the combined effects of saw blade cutting force, template weight, and mechanical vibration, this uncut area is very prone to premature breakage. Breakage often occurs at the end of the template, and the fracture surface is uneven, easily forming notches, burrs, or tears at the corners of the template, affecting the cutting quality and finished product precision. Especially when the width of the part to be cut is narrow, due to the limited support area of ​​the cut area, it is difficult to achieve sufficient fixation. The template is prone to shaking or shifting during the cutting process, further leading to uneven stress. At this time, the saw blade cutting force and the template weight work together to cause the uncut connecting parts to break prematurely, producing irregular chipping or burrs. To solve the above problems, we propose a cutting device and method for multi-layer building templates. Summary of the Invention

The inner side of the U-shaped frame is vertically slidably connected to a guide post, which is fixedly connected to both ends of the saw blade. One end of the guide post is slidably connected to the bottom of the movable plate.

[0009] Furthermore: the vertical cutting mechanism includes a cylinder, which is fixedly installed on the upper side of the machine tool.

[0016] Compared with the prior art, the beneficial effects of the present invention are: In this invention, two sets of side-cutting mechanisms are used to laterally cut multi-layer building templates until the residual ribs are formed, avoiding tearing when the saw teeth encounter a fracture section at an unsupported edge. The vertical cutting mechanism finishes the cut with a clean cut, allowing for better edge quality control of rotation speed and feed. This significantly improves the cutting effect when cutting brittle or easily chipped coated plywood, oriented strand board, and other building templates. The cleaning mechanism, through a U-shaped frame, follows the saw blade's cutting process. The guide column, in conjunction with the toothed plate, causes the brush roller to rotate and clean residual wood chips from the cut surface. The brush roller, through a one-way gear combination, ensures that the brush bristles always align with the cutting direction during the saw blade's back-and-forth movement. This avoids the problem of tearing caused by burrs against the grain during cutting, and the brush bristles aligned with the wood grain reduce the risk of fiber breakage and prevent burrs from embedding deeper. Furthermore, it straightens and flattens burrs, reducing the risk of workers being scratched or injured by burrs at the edges during subsequent manual handling. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-11The figure shows a preferred embodiment of the present invention, a cutting device and method for multi-layer building templates, including a machine tool 1. The top of the machine tool 1 is provided with a positioning component 2, a cutting component 3 and a cleaning mechanism 4. The positioning component 2 is used to press the multi-layer building template 43 and press it along the cutting direction of the multi-layer building template 43 so that the cutting part is close and stable. There are two sets of cutting components 3, each set including a side cutting mechanism 5 and a vertical cutting mechanism 6. The side cutting mechanism 5 is used to cut from both sides of the multi-layer building template 43 towards the middle, and the vertical cutting mechanism 6 is used to cut off the uncut residual ribs. The cleaning mechanism 4 is located on one side of the cutting component 3 and rotates along the cutting direction of the cutting component 3 to remove residual wood chips on the cutting surface of the multi-layer building template 43.

[0021] The side-cutting mechanism 5 includes a turntable 7, with a connecting rod 8 fixedly installed at the center of the turntable 7. One end of the connecting rod 8 is rotatably connected to a second connecting rod 9, and the other end of the second connecting rod 9 is rotatably connected to the upper end of a movable plate 10. Two saw blades 11 are slidably connected to the bottom of the movable plate 10. The side-cutting mechanism 5 also includes a screw 12, with reverse threads at both ends of the screw 12 and each connected to a mounting block 13. The mounting blocks 13 are slidably connected to the upper side of the machine tool 1, and one end of each mounting block 13 is fixedly connected to a U-shaped frame 14. A guide post 15 is vertically slidably connected to the inner side of the U-shaped frame 14. The guide post 15 is fixedly connected to both ends of the saw blades 11. One end is slidably connected to the bottom of the movable plate 10; the vertical cutting mechanism 6 includes a cylinder 16, which is fixedly installed on the upper side of the machine tool 1. A cutting support 17 is fixedly installed on the movable end of the cylinder 16. A saw blade 18 is rotatably connected to one end of the cutting support 17. A pusher mechanism 19 is provided on one side of the saw blade 18. The pusher mechanism 19 includes a support rod 30, which is fixedly installed at the lower end of the cutting support 17. A push roller 31 parallel to the cutting surface of the multi-layer building template 43 is rotatably connected to the inner side of the support rod 30. A movable ring 32 is meshed in the middle of the push roller 31 in the form of a helical gear. The movable ring 32 is fixedly installed at the center of the saw blade 18.

[0022] It can be seen that the core of the present invention lies in the use of two sets of side cutting mechanisms 5 to cut the multi-layer building template 43 laterally until the residual ribs are formed, so as to avoid the saw teeth from tearing when they encounter the fracture section at the unsupported edge. The vertical cutting mechanism 6 finishes the cut with a clean cut, which can control the rotation speed and feed to obtain better edge quality. The effect is significantly improved when cutting building templates 43 such as brittle or easily chipped coated plywood and oriented strand board.

[0023] The cleaning mechanism 4 includes a tail box 20, which is fixedly connected to the outside of the U-shaped frame 14. A connecting rod 21 is fixedly connected to one end of the tail box 20, and the connecting rod 21 is slidably connected to one end of the saw blade 11. A brush roller 22 is rotatably connected to the side of the tail box 20 near the cutting surface of the multi-layer building template 43. Two one-way combination gears 23 are meshed at the bottom of the brush roller 22. A drive gear 24 is meshed at one end of the one-way combination gear 23. A toothed plate 25 with the size matching the one-way combination gear 23 and the drive gear 24 is fixedly installed inside the machine tool 1. The one-way combination gear 23 includes a lower wheel body 26 and an upper wheel body 27. One end of the lower wheel body 26 meshes with the drive gear 24 or the toothed plate 25. A pawl 28 is provided at the axis of the lower wheel body 26. A ratchet 29 matching the size and direction of the pawl 28 is provided on the inner wall of the upper wheel body 27. The outer wall of the upper wheel body 27 meshes with the outer wall of the brush roller 22.

[0024] like Figure 6 The end of the tail box 20 away from the saw blade 11 and the cutting surface has a slightly outwardly extended arc, so as to push the cut part of the multi-layer building template 43 outward slightly during cutting, so as to facilitate the movement of the saw blade 11. Regarding the cleaning mechanism 4, the cleaning mechanism 4 can follow the cutting process of the saw blade 11 through the U-shaped frame 14 and clean the residual wood chips on the cut surface after the guide post 15. The brush roller 22, through the one-way combination gear 23, makes the brush bristles always follow the cutting direction when the saw blade 11 moves back and forth. In this way, when cleaning the residual wood chips on the cut surface, firstly, it avoids the problem of burrs generated by cutting being easy to tear against the grain. The brush bristles with the grain can reduce the risk of fiber breakage and prevent burrs from embedding deeper. Secondly, it can straighten the burrs and reduce the risk of burrs at the edges and corners scratching or pricking workers during subsequent manual handling.

[0025] The positioning component 2 includes a pressing cylinder 33, the movable end of which pushes a pusher plate 34 in the horizontal direction, a second pressing cylinder 35 is fixedly installed on the top of the pusher plate 34, and a pressing plate 36 is fixedly installed on the movable end of the second pressing cylinder 35; a pusher cylinder 37 is fixedly installed on one end of the U-shaped frame 14, and the movable end of the pusher cylinder 37 is slidably connected to the top of the second pressing plate 38.

[0026] The pressing cylinder 33 pushes the pusher plate 34 to push the cutting surface of the multi-layer building template 43 to the position aligned with the saw blade 11. Then, the second pressing cylinder 35 pushes the pressing plate 36 to press one end of the template. The pusher cylinder 37 pushes the second pressing plate 38 to press the template tightly against the cutting surface of the multi-layer building template 43, preventing the cutting edge from lifting, tearing or producing burrs due to vibration or uneven force during the cutting process.

[0027] The upper surface of the machine tool 1 is rotatably connected with several rotating rollers 39. The surface of the rotating rollers 39 is also provided with a material discharge groove 40, an opening 41 and a positioning groove 42. The rotating rollers 39 facilitate the movement of the multi-layer building template 43 on the machine tool 1. The multi-layer building template 43 can be forked onto the machine tool 1 by a forklift. The material discharge groove 40 is used to clean out the wood strips cut from the multi-layer building template 43. The opening 41 allows the saw blade 11 and the U-shaped frame 14 to move on the machine tool 1. The positioning groove 42 is used to allow the mounting block 13 to move back and forth stably on the surface of the screw 12.

[0028] It should be added that, Figure 3 In the diagram, for ease of illustration, some structures of the cutting component 3 and cleaning mechanism 4 are shown. Figure 3 As not shown, the machine tool 1 is equipped with several motors. The turntable 7, screw 12, and saw blade 18 are all rotated by corresponding motors. The motors and cylinders are controlled by control switches. The control methods include electrical signal control or control by infrared signals, which are common and not the focus of this invention. They will not be elaborated on here. In the embodiment, the ratchet mechanism composed of pawl 28 and ratchet 29 has been fully disclosed in the prior art. The most common example is the ratchet mechanism in a bicycle used for unidirectional drive. Its principle will not be elaborated on here.

[0029] In this embodiment, during cutting, specifically, a multi-layer template is placed and aligned on the machine tool 1. The pressure cylinder 33 pushes the pusher plate 34 to push the surface of the multi-layer building template 43 to be cut to the position aligned with the saw blade 11. Then, the second pressure cylinder 35 pushes the pressure plate 36 to press one end of the template, and the pusher cylinder 37 pushes the second pressure plate 38 to press the template tightly against the cut surface of the multi-layer building template 43. The motor controls the turntable 7 to rotate, and drives the second connecting rod 9 to rotate through the connecting rod 8. The second connecting rod 9 then reciprocates to pull the movable plate 10 vertically, pulling the saw blade 11 to cut the template. During the process, the screw 12 is electrically... The machine rotates under the action of the machine, and the U-shaped frame 14 moves laterally controlled by the mounting block 13. Since the U-shaped frame 14 drives the saw blade 11 to move inward to cut the template through the guide column 15, after cutting to the residual rib at the set depth, the cylinder 16 controls the cutting support 17 to continuously descend, and the motor controls the saw blade 18 to rotate to cut the residual rib. The saw blade 18 drives the movable ring 32 to rotate, and the movable ring 32 meshes with the middle of the push roller 31 in the form of a helical gear, driving the push roller 31 to rotate, and cleaning the cut and separated part out of the underside of the saw blade 18, without affecting the cutting of the multi-layer building template 43 by the saw blade 18. Figure 9 As shown, it should be added that the distance between the lower end of the push roller 31 and the saw blade 18 is not less than the thickness of the single-layer building template 43, so that it can be pushed away after the single-layer building template 43 is completely cut. The connection between the support rod 30 and the movable ring 32 and the push roller 31 does not have any protruding parts, so as not to affect the initial contact between the push roller 31 and the building template 43. During the cutting process, such as Figure 3 and Figure 6-8 As shown, during the movement of the U-shaped frame 14 and the saw blade 11, the brush roller 22 also moves along with it. Two one-way gears 23 drive the brush roller 22 to rotate when it approaches the center of the template and when it moves away from the center. The brush roller 22 has hard bristles on its surface, such as... Figure 7 As shown in the figure, the one-way combination gear 23 and drive gear 24 on the left side of the brush roller 22 are used when it is far from the center of the template, while the one-way combination gear 23 on the right side of the brush roller 22 is used when it is close to the center of the template. The arrows indicate the direction in which it drives the brush roller 22 to rotate. Taking the brush roller 22 close to the center of the template as an example, the lower wheel body 26 of the one-way combination gear 23 on the right side meshes with the toothed plate 25. Since the rotation direction of the lower wheel body 26 matches the direction of its internal pawl 28 and ratchet 29, the pawl 28 pushes the upper wheel body 27 to mesh with the brush roller 22 through the ratchet 29, thus driving the brush roller 22 to rotate. At this time, the upper wheel body 27 on the left side of the one-way combination gear 23 does not match the direction of its internal pawl 28 and ratchet 29, so the left side... The upper wheel 27 rotates freely. The left one-way combination gear 23 is relative to the right one-way combination gear 23. Since it is used for the return stroke, a drive gear 24 is added. The drive gear 24 rotates by contacting the toothed plate 25. Similarly, when the left one-way combination gear 23 drives the brush roller 22 to rotate in a fixed direction, the upper wheel 27 on the right one-way combination gear 23 rotates freely. This ensures that the rotation direction of the brush roller 22 is always along the cutting direction during the back-and-forth movement. In this way, when cleaning the residual wood chips on the cut surface, firstly, it avoids the problem of burrs from the cutting process being easy to tear against the grain. The brush bristles along the wood grain can reduce the risk of fiber breakage and prevent burrs from embedding deeper. Secondly, it can straighten and flatten the burrs, reducing the risk of burrs at the edges and corners scratching or pricking workers during subsequent manual handling.
