Description

Technical Field

[0001] The invention relates to the technical field of section steel cutting, in particular to a cutting device for producing T-section steel. Background Art

[0002] Embedded T-steel is mainly used in railway bridges, building structures and other fields. T-shaped steel is needed to prepare embedded T-steel. T-shaped steel is named because its cross section is the same as the English letter "T". In the production of T-shaped steel, H-shaped steel is often directly cut into T-shaped steel.

[0003] In the prior art, the production of T-shaped steel by splitting H-shaped steel is usually carried out by thermal cutting, such as flame cutting, plasma cutting, etc. The temperature at the cutting point of thermal cutting is high and the heat is concentrated. Thermal deformation and cutting slag are prone to occur at the cutting point. Thermal deformation affects subsequent processing and use. The cutting slag requires secondary grinding, which adds additional processes and costs, affecting the production efficiency and product quality of T-shaped steel.

[0004] The H-beam splitting method can also be used to produce T-beam by cold cutting, using a sawing machine to cut and split the H-beam. Although the cold cutting method can avoid thermal deformation and cutting slag, the cold cutting method requires the H-beam to be cut by a vertical cutting sawing machine to obtain an H-beam billet that matches the length of the T-beam, and then the H-beam billet is transferred to another horizontal cutting sawing machine, and cut along the center line of the web of the H-beam billet to obtain the T-beam. The transfer of the H-beam billet and the positioning of the two cuts are time-consuming and labor-intensive, and there is a problem of low production efficiency. Summary of the invention

The transverse bracket 41 is fixedly mounted on both sides of the frame 1. The horizontal linear drive device 42 is fixedly mounted on one of the transverse brackets 41. The band saw assembly 43 includes a band saw housing 431, a band saw driving pulley 432, a band saw driven pulley 433, a band saw driving mechanism 434, and a saw band 435. The band saw driving pulley 432 and the band saw driven pulley 433 can be rotatably arranged in the band saw housing 431. The saw band 435 is mounted on the band saw driving pulley 432 and the band saw driven pulley 433. The saw band 435 passes through the transverse cutting opening 12. The band saw driving mechanism 434 drives the band saw driving pulley 432 to rotate. The output end of the horizontal linear drive device 42 is connected to the band saw housing 431, and is used to drive the saw belt 435 to move linearly in the transverse cutting opening 12, so that the saw belt 435 can perform transverse cutting on the H-shaped steel 6; the horizontal linear drive device 42 uses an electric slide, which can drive the band saw assembly 43 to move horizontally accurately, so that the saw belt 435 can accurately and stably cut the H-shaped steel 6; the wheel surfaces of the band saw driving pulley 432 and the band saw driven pulley 433 are both provided with an annular groove adapted to the saw belt 435, and the saw belt 435 can be stuck in the annular groove to avoid separation; the band saw driving pulley 432 is driven to rotate by the band saw driving mechanism 434, and the band saw driving pulley 432 drives the band saw driven pulley 433 to rotate through the saw belt 435; The transverse cutting mechanism 4 is provided with a secondary cutting point 15, a starting cutting point 13 and a terminal cutting point 14 arranged in sequence. When the head end of the H-beam 6 is at the starting cutting point 13, the vertical cutting mechanism 3 performs vertical cutting on the H-beam 6 at the vertical cutting notch 11, and at the same time, the saw belt 435 performs the initial transverse cutting on the H-beam 6 at the starting cutting point 13, and completes the initial transverse cutting on the H-beam 6 at the terminal cutting point 14; wherein the terminal cutting point 14 is located between the starting cutting point 13 and the transverse cutting opening 12; after the vertical cutting mechanism 3 completes the vertical cutting of the H-beam 6, and the saw belt 435 completes the initial transverse cutting of the H-beam 6 , the H-beam 6 is cut into semi-finished H-beam 64 and tail H-beam 65; when the head end of the tail H-beam 65 moves to the starting cutting point 13, the vertical cutting mechanism 3 vertically cuts the tail H-beam 65 at the vertical cutting notch 11, and at the same time, the saw belt 435 performs secondary transverse cutting on the semi-finished H-beam 64 at the secondary cutting point 15, and completes the secondary transverse cutting of the semi-finished H-beam 64 at the starting cutting point 13 to obtain the finished T-beam, and completes the initial transverse cutting of the tail H-beam 65 at the end cutting point 14; wherein, the secondary cutting point 15 is located on the side of the starting cutting point 13 facing away from the end cutting point 14.

[0019] In order to facilitate the automatic cutting of the H-beam 6, a fiber optic sensor 7 is installed on the frame 1, and the fiber optic sensor 7 is located at the starting cutting point 13. This embodiment is also provided with a controller, which is electrically connected to the fiber optic sensor 7, and is electrically connected to each electrical component in the conveying mechanism 2, the vertical cutting mechanism 3, and the horizontal cutting mechanism 4. When the head end of the H-beam 6 or the tail end of the semi-finished H-beam 64 or the head end of the tail H-beam 65 passes through the starting cutting point 13, the fiber optic sensor 7 can detect a signal. When the head end of the H-beam 6 moves to the starting cutting point 13, when the fiber optic sensor 7 detects the head end of the H-beam 6, the horizontal cutting mechanism 4 and the vertical cutting mechanism 3 work to cut the H-beam 6.

[0020] like Figure 1 As shown, since the saw belt 435 cannot get close to the vertical cutting notch 11, when the vertical cutting mechanism 3 and the horizontal cutting mechanism 4 complete the cutting of the H-beam 6, the semi-finished H-beam 64 is not completely transversely split, so it is necessary to perform a secondary transverse cutting on the semi-finished H-beam 64; when the horizontal linear drive device drives the saw belt 435 to move to the end cutting point 14, it will no longer move forward, but will automatically move in the reverse direction to reset and move to the secondary cutting point 15; then the semi-finished H-beam 64 and the tail H-beam 65 are synchronously moved by the conveying mechanism 2, and when the head end of the tail H-beam 65 moves to the starting cutting point 13, as shown in FIG. Figure 2 As shown, the optical fiber sensor 7 detects a signal, and then the transverse cutting mechanism 4 and the vertical cutting mechanism 3 work again, as shown in FIG. Figure 3 As shown, the vertical cutting mechanism 3 performs vertical cutting on the tailing H-shaped steel 65, and the horizontal cutting mechanism 4 performs secondary cutting on the semi-finished H-shaped steel 64, and after completing the cutting of the semi-finished H-shaped steel 64, continues to perform horizontal cutting on the tailing H-shaped steel 65, thereby improving the processing efficiency; The H-beam 6 is cut horizontally by the horizontal cutting mechanism 4, and is cut vertically by the vertical cutting mechanism 3. The horizontal cutting mechanism 4 and the vertical cutting mechanism 3 cut the H-beam 6 at the same time, and there is no need to transfer the H-beam 6, which saves time and effort and can improve the cutting efficiency of the H-beam 6.

[0021] In a preferred embodiment, to ensure cutting stability, Figures 1 to 7As shown, the present embodiment is further provided with two limiting mechanisms 5, which are respectively located on both sides of the starting cutting point 13; the limiting mechanism 5 includes a downward pressure linear drive device 51, an upper pressure block 52, a side pressure linear drive device 53, and a side pressure block 54. The downward pressure linear drive device 51 is fixedly installed on the top of the frame 1, and the upper pressure block 52 is installed at the output end of the downward pressure linear drive device 51. The upper pressure block 52 is used to abut and cooperate with the upper end surface of the upper flange plate 62 of the H-shaped steel 6. The side pressure linear drive device 53 is symmetrically arranged on both sides of the frame 1, and the side pressure linear drive device 53 is fixedly connected to the frame 1. The side pressure block 54 is installed at the output end of the side pressure linear drive device 53. The side pressure block 54 is used to abut and cooperate with the web 63 of the H-shaped steel 6. The downward pressure linear drive device 51 and the side pressure linear drive device 53 are both hydraulic cylinders, and the downward pressure linear drive device and the side pressure linear drive device 53 are both controlled and operated by a controller. In other embodiments, the downward pressure linear drive device 51 and the side pressure linear drive device 53 can also be pneumatic cylinders or electric cylinders.

[0022] When the H-shaped steel 6 is cut, the limiting mechanism 5 on the side of the starting cutting point 13 toward the end cutting point 14 works, such as Figure 1 As shown, the downward pressure linear drive device 51 drives the downward pressure block to press the upper flange plate 62 of the H-beam 6; the two side pressure linear drive devices 53 work synchronously to drive the side pressure blocks 54 to move together, so that the side pressure blocks 54 cooperate to clamp the web 63 of the H-beam 6, thereby achieving the positioning of the H-beam 6 and preventing the H-beam 6 from being moved by force during cutting. When the saw belt 435 performs a secondary transverse cutting on the semi-finished H-beam 64, as shown in FIG. Figure 2 and Figure 3 As shown, the limiting mechanism 5 on the side of the starting cutting point 13 facing away from the ending cutting point 14 works in the same principle as above to achieve the clamping and positioning of the semi-finished H-shaped steel 64 .

[0023] In a preferred embodiment, in order to facilitate driving the upper supporting wheel 21 and the lower conveying roller 22 to move synchronously, as shown in FIG.

[0024] By dividing the upper supporting wheels 21 of the upper supporting wheel group into a front upper supporting wheel group and a rear upper supporting wheel group at the vertical cutting notch 11, no chain transmission connection is set between the upper supporting wheels 21 on both sides of the vertical cutting notch 11. Figure 7 As shown, interference with the saw disc 333 can be avoided when the saw disc 333 descends, ensuring that the saw disc 333 descends smoothly to the lower dead point.

[0025] The first chain transmission assembly 23, the second chain transmission assembly 24, the third chain transmission assembly 25, the fourth chain transmission assembly 26, the fifth chain transmission assembly 27, and the sixth chain transmission assembly 29 are all composed of two sprockets and a chain connecting the two sprockets, which can realize the synchronous movement of the upper supporting wheel 21 and the lower conveying roller 22.

[0026] In a preferred embodiment, in order to enable the lifting linear drive device 32 to drive the circular saw cover 331 to lift smoothly, the vertical cutting mechanism 3 further includes a vertical guide rail 34, which is vertically arranged, fixedly connected to the vertical bracket 31, and a slider of the vertical guide rail 34 is fixedly connected to the circular saw cover 331.
