[0002] In construction, in order to make some building materials such as plates, steel bars or columnar profiles meet the actual on-site processing requirements, cutting equipment is often needed to further cut and process the building materials.

[0003] For example, Chinese invention CN118455622A discloses a building material cutting device. The workpiece is clamped and fixed by an arc-shaped clamping plate. During cutting, the rotating ring drives the workpiece to rotate relative to the fixed frame, and the hydraulic telescopic rod drives the electric saw to move downward in the protective shell, so that the workpiece can be cut by the electric saw.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0034] See also Figures 1 to 4 As shown, the present invention is a building material cutting device, including a vertically arranged frame plate 1, the frame plate 1 is provided with a through hole 101, and a ring plate 2 arranged concentrically with the through hole 101 is rotatably connected through a guide rail slider assembly, and the building material passes through the through hole 101 during cutting.

[0035] The frame plate 1 is connected to a driving device for driving the annular plate 2 to rotate in a circle. For example, the driving device includes a driving motor 102 connected to the frame plate 1, and a worm 103 drivingly connected to the output shaft of the driving motor 102. The annular plate 2 is fixedly connected to a worm gear ring 203 meshing with the worm 103, so that the worm 103 is driven to rotate by the driving motor 102, and the annular plate 2 is driven to perform a rotational motion by utilizing the meshing transmission of the worm 103 and the worm gear ring 203.

[0036] like Figures 5 to 8 As shown, the annular plate 2 is fixedly connected to the mounting plate 201 via a connecting block, the mounting plate 201 is slidably connected to the sliding seat 202 , and the sliding direction of the sliding seat 202 coincides with the diameter direction of the annular plate 2 .

[0037] The sliding seat 202 is connected with a saw component and is drivingly connected with a feeding mechanism, which is used to drive the sliding seat 202 to move through the feeding mechanism and drive the saw component to rotate circumferentially through the annular plate 2, so as to realize circumferential cutting around the building material.

[0038] Specifically, the saw component includes a stepped shaft 3 rotatably connected to the sliding seat 202. The stepped shaft 3 is connected with a saw blade 301. For example, if the stepped shaft 3 has a threaded section, after the saw blade 301 is inserted through the stepped shaft 3, it is locked by cooperating with a nut through the threaded section to realize the installation of the saw blade 301.

[0039] The sliding seat 202 is fixedly connected with a motor 302 through a motor bracket, and the output shaft of the motor 302 is connected with the stepped shaft 3 through a coupling. Thus, the saw blade 301 is driven to rotate by the motor 302. When the saw blade 301 needs to be disassembled, only the coupling needs to be disassembled and then the nut can be disassembled.

[0040] Meanwhile, the feeding mechanism includes a feeding lead screw 204 rotatably connected to the mounting plate 201 through a bearing block and a feeding drive component drivingly connected with the feeding lead screw 204. The sliding seat 202 is fixedly connected with a nut cooperating with the feeding lead screw 204. The feeding lead screw 204 is driven to rotate by the feeding drive component to realize the movement of the position of the sliding seat 202.

[0041] Among them, the feeding lead screw 204 is rotatably connected to one side of the mounting plate 201 close to the sliding seat 202, and the feeding drive component can be a stepping motor. Every time the annular plate 2 rotates one circle, the stepping motor drives the feeding lead screw 204 to rotate a certain number of circles, so that the sliding seat 202 moves a certain distance to realize the cutting feed of the saw blade 301.

[0042] As another implementation manner, as Figure 7 and 8 shown, the drive component includes a transmission shaft 205 rotatably connected to the mounting plate 201. The transmission shaft 205 is rotatably connected to the mounting plate 201 on the side far from the sliding seat 202 through a bearing block. One end of the transmission shaft 205 is drivingly connected with the feeding lead screw 204, and the other end is fixedly connected with a traveling wheel 206. The transmission between the transmission shaft 205 and the feeding lead screw 204 can be carried out through a synchronous belt and a synchronous belt pulley, or by using a sprocket and a chain for transmission.

[0043] Moreover, the frame plate 1 is welded or connected with a fixed support plate 104 through screws, and the fixed support plate 104 is fixedly connected with an arc-shaped rack 105 concentrically arranged with the annular plate 2, and the arc-shaped rack 105 corresponds to the moving track of the traveling wheel 206. When the annular plate 2 rotates, when the traveling wheel 206 meshes with the arc-shaped rack 105, as the annular plate 2 rotates, the traveling wheel 206 rolls along the arc-shaped rack 105 and drives the feeding lead screw 204 to rotate through the transmission shaft 205, so as to realize the feeding movement of the sliding seat 202.

[0044] At the same time, by replacing the arc-shaped racks 105 of different lengths, the number of revolutions that the transmission shaft 205 drives the feed screw 204 to rotate each time can be adjusted, so that the cutting feed amount of the saw blade 301 can be flexibly adjusted according to different building materials.

[0045] like Figure 9 As shown, the fixed support plate 104 is welded or screwed to fix the mounting block 106, the mounting block 106 is provided with an arc-shaped channel 107 adapted to the arc-shaped rack 105, and the side wall of the arc-shaped channel 107 is evenly provided with threaded through holes 108, screws are connected through the threaded through holes 108, and the arc-shaped rack 105 is squeezed and fixed by the end of the screw by screwing the screw. The arc-shaped channel 107 facilitates accurate positioning of the installation position of the arc-shaped rack 105, and the arc-shaped rack 105 can be disassembled by screwing the screw, which is conducive to improving the convenience of replacing the arc-shaped rack 105.

[0046] As another preferred embodiment, the rack plate 1 is fixedly connected to a base plate 109, which is vertically arranged between the base plate 109 and the rack plate 1, and is supported and fixed by the base plate 109. The base plate 109 is connected to two support platforms 4, which are respectively located on both sides of the rack plate 1.

[0047] Specifically, the support platform 4 is a scissor-type screw lifting platform, which is convenient for adjusting the support height of the support platform 4 for the building materials, so that the height can be flexibly adjusted according to the different sizes of building materials, so that the building materials remain located at the center of the through-port 101, so that during the rotation of the annular plate 2, the cutting amount of the saw blade 301 rotating around the circumference of the building material will not produce a large difference, which is beneficial to improving the stability and reliability of the cutting.

[0048] In addition, the supporting platform 4 includes a screw rod 401, and the screw rods 401 of the two supporting platforms 4 are connected by a connecting shaft transmission, so that the two screw rods 401 can rotate synchronously, and are used to synchronously adjust the supporting heights of the two supporting platforms 4, so that the supporting heights of the two supporting platforms 4 can be kept consistent, avoiding the height difference between the two supporting platforms 4, which may cause large impact and vibration after the building materials are cut.

[0049] At the same time, the lower surface of the support platform of the support platform 4 is rotatably connected with a screw rod 402, and the guide rail slider assembly is slidably connected with two sliding plates 403, and the sliding plates 403 are fixedly connected with a threaded sleeve of the screw rod 402. The screw rod 402 can be provided with threads in opposite directions at both ends, and the two sliding plates 403 are driven to move toward each other by rotating the screw rod 402, or the two sliding plates 403 are driven to move in opposite directions by rotating in the opposite direction. Handles or hand wheels can be installed at both ends of the screw rod 402 to facilitate manual rotation of the screw rod 402, and the screw rod 402 can also be driven to rotate by a motor to realize automatic control.

[0050] Both sliding plates 403 are connected with clamping plates 405 through connecting rods 404. The two clamping plates 405 are opposite in position and are located on the upper surface of the support platform 4. They are used to drive the two sliding plates 403 to move towards each other through the screw 402, and use the two clamping plates 405 to clamp and fix the building materials, so as to improve the convenience of clamping and fixing the building materials and ensure the stability of the building materials during cutting.
