[0029] Example

[0030] As mentioned in the background technology, when a house is built, the size of the tube / rod-shaped member 14 usually cannot meet the use requirements and needs to be cut according to the actual size before use. However, the existing cutting device has certain defects. It shakes greatly during cutting, which can not guarantee the cutting quality and poses a threat to the working environment of the staff. Therefore, the inventor has made improvements based on the existing cutting device and designed a new cutting device, which is described in detail below with reference to the drawings.

[0031] This embodiment provides a building material cutting device. Figure 1, including a frame 1, the frame 1 is horizontally extended, a cutting platform 2 is installed on the frame 1, a mounting frame 3 is hinged on the cutting platform 2, and a cutting saw blade 5 is connected to the mounting frame 3 through a driving device 4, the mounting frame 3 is consistent with the design of the cutting machine in the prior art, that is, it can drive the driving device 4 and the cutting saw blade 5 to move toward the cutting platform 2, and after the cutting is completed, the mounting frame 3 can drive the driving device 4 and the cutting saw blade 5 to reset, and a cutting groove is opened at the corresponding position of the cutting saw blade 5 on the cutting platform 2 to facilitate accommodating the cutting saw blade 5 during cutting.

[0032] As one of the main technical points of this solution, Figure 2 , it is possible to fix the pipe / rod-shaped member 14 near the cutting position to improve stability. A mounting seat 6 is provided on the cutting platform 2 on one side of the cutting saw blade 5, and a mounting groove 7 is provided in the mounting seat 6. The mounting groove 7 is long and its direction is perpendicular to the extension direction of the rotating shaft of the cutting saw blade 5. A threaded rod 8 is rotatably connected in the mounting groove 7, and the extension direction of the threaded rod 8 is perpendicular to the extension direction of the rotating shaft of the cutting saw blade 5, that is, perpendicular to the extension direction of the pipe / rod-shaped member 14 when cutting, and one end of the threaded rod 8 extends to the outside of the mounting seat 6 and is connected to a knob 9. Through the knob 9 It can drive the threaded rod 8 to rotate. The threaded rod 8 is threadedly connected to a sleeve 10. The bottom of the sleeve 10 is slidingly connected to the bottom of the mounting groove 7, and the upper end of the sleeve 10 is connected to a movable clamping seat 11. The movable clamping seat 11 extends beyond the upper end of the mounting seat 6. A fixed clamping seat 12 is provided on one side of the upper end of the mounting seat 6. The threaded rod 8 is driven to rotate by the knob 9, which can drive the sleeve 10 to move along the threaded rod 8, and then drive the movable clamping seat 11 to move in a direction toward or away from the fixed clamping seat 12, thereby realizing the clamping and releasing of the tube / rod-shaped member 14.

[0033] Moreover, the side of the movable clamping seat 11 close to the fixed clamping seat 12 is set to an arc shape, so that it can adapt to the outer edge surface of the tube / rod-shaped member 14 when clamping, and the fixed clamping seat 12 is provided with a groove 15 on the side close to the movable clamping seat 11. The groove 15 is opened vertically downward, and a contact wheel 16 is installed in the groove 15. In this embodiment, two contact wheels 16 are arranged in the groove 15 from top to bottom, and the side of the contact wheel 16 close to the movable clamping seat 11 extends beyond the fixed clamping seat 12, so that when the tube / rod-shaped member 14 is clamped, the contact wheel 16 can first contact the tube / rod-shaped member 14, thereby reducing the wear between the fixed clamping seat 12 and the tube / rod-shaped member 14 to be cut, and protecting the outer edge surface of the fixed position of the tube / rod-shaped member 14.

[0034] And on the basis of the above structure, the distance between the vertical middle surface of the movable clamping seat 11 and the vertical plane where the cutting saw blade 5 is located does not exceed 15 cm, so that the fixed position of the tube / rod-shaped member 14 during cutting does not exceed 15 cm from the cutting position, preventing the fixing effect from being unclear due to the distance being too far, and improving the stability of the fixation.

[0035] In this embodiment, a limit assembly 13 is provided on the frame 1 on one side of the cutting platform 2. Figure 3 and Figure 5 , can support the pipe / rod-shaped member 14 to be cut, and can also guide the pipe / rod-shaped member 14 to move to the bottom of the cutting saw blade 5, wherein the limiting assembly 13 includes a limiting cylinder 131 installed on the frame 1, and the length of the limiting cylinder 131 should be not less than 10 cm to ensure the effect of supporting and guiding the pipe / rod-shaped member 14, and the axis of the limiting cylinder 131 is parallel to the extension direction of the rotation axis of the cutting saw blade 5, and the side wall of the mounting cylinder is connected to a screw 132 that penetrates into the mounting cylinder through a threaded connection. In this embodiment, the screw 132 is provided with four, and is arranged in an array relative to the axis of the limiting cylinder 131, that is, in the side view direction, the screw 132 is located at the upper, lower, left and right positions of the limiting cylinder 131, which can improve the supporting effect, and the screw 13 The end portion located outside the mounting cylinder is connected to a handwheel 133, and the other end is connected to a limiting plate 134 via a bearing seat. A plurality of limiting wheels 135 are installed on the side of the limiting plate 134 away from the screw rod 132, and the rotation axis extension direction of the limiting wheels 135 is perpendicular to the extension direction of the axis of the limiting cylinder 131. That is, the rotation direction of the limiting wheels 135 is consistent with the movement direction of the tube / rod-shaped member 14, which can support and guide it. First, the positions of the four screw rods 132 are adjusted according to the diameter of the tube / rod-shaped member 14. Then, through the connection of the bearing seat, the limiting plate 134 can be pushed or pulled to the appropriate position. Then, the tube / rod-shaped member 14 is inserted into the limiting cylinder 131, and the tube / rod-shaped member 14 moves toward the mounting seat 6 along the four sets of limiting wheels 135.

[0036] In addition, an L-shaped plate 17 is installed on the cutting platform 2. Figure 6 , and is located between the mounting seat 6 and the limiting assembly 13, the L-shaped plate 17 is fixed to the cutting platform 2, and a support wheel 18 is installed at the vertical end of the L-shaped plate 17, and the extension direction of the rotating shaft of the support wheel 18 is parallel to the threaded rod 8. After the tube / rod-shaped member 14 passes through the limiting cylinder 131, it can be placed on the support wheel 18, and the support wheel 18 can guide the tube / rod-shaped member 14 and support the tube / rod-shaped member 14 to ensure that it can stably enter between the movable clamping seat 11 and the fixed clamping seat 12.

[0037] It should be noted that, combined with Figure 4In this solution, a pressure handle 19 is set above the mounting frame 3. The pressure handle 19 can drive the driving device 4 and the cutting saw blade 5 to move toward the cutting pipe / rod-shaped member 14 to complete the cutting action. In order to realize automatic cutting, a vertical frame 20 is installed on the rear side of the frame 1. The top of the vertical frame 20 is hinged with a hydraulic cylinder 21. The hydraulic cylinder 21 is tilted downward and the output end is hinged to the mounting frame 3. The driving device 4 and the cutting saw blade 5 can be driven downward by the drive of the hydraulic cylinder 21, and the retraction of the output end of the hydraulic cylinder 21 can drive the overall reset.
