Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a tube cutting machine protection mechanism and a laser tube cutting machine using the same. Background Art

[0002] Laser tube cutting machine is a high-speed, high-efficiency and high-precision cutting equipment, which is widely used in the field of tube cutting. Since the length of the cut tube can be customized, most of the bed is the conveying area of ​​the tube. In order to adapt to tubes of different diameters, several support wheels are provided in the conveying area. When working, the operator needs to stand on the outside of the bed, adjust the height of these support wheels along the length direction of the bed and install the tube.

[0003] In order to facilitate the operators to perform the above operations, the laser tube cutting machine usually adopts an open design, and there must be no obstructions in the areas on both sides above the working plane of the entire bed. However, this design will inevitably injure operators or pedestrians when it is working. Although a protective cover can be directly installed on the bed, it is not convenient for the operator to operate. Therefore, it is necessary to ensure the safety of the operator while taking into account the convenience of the operator's operation. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a tube cutting machine protection mechanism and a laser tube cutting machine using the same.

[0005] The technical solution of this utility model is as follows:

[0006] A pipe cutting machine protection mechanism comprises an upper guard plate arranged vertically, a telescopic mechanism capable of driving the upper guard plate to be lifted and lowered in a vertical direction is provided on one side of the upper guard plate, and a guiding mechanism capable of providing a guiding effect for its lifting and lowering, the telescopic mechanism comprises a telescopic cylinder arranged vertically, an upper end of which is connected to the upper guard plate, and a first mounting seat capable of being connected to a bed of a pipe cutting machine body is provided at the lower end, and it can be understood that the upper end of the telescopic cylinder can also be connected to the upper guard plate through a mounting seat to ensure stability and adjustability. In summary, when the protection mechanism is applied to the cutting machine equipment, the upper guard plate is first connected to the side of the bed of the pipe cutting machine body that needs to be safely protected through the first mounting seat, and then the piston is extended by driving the telescopic cylinder. The rod makes the upper guard plate rise vertically to above the working plane on the side of the pipe cutting machine main body that needs safe protection, and during the lifting and lowering process of the upper guard plate, it can be guided by the guide mechanism to ensure the smooth movement of the upper guard plate, thereby realizing the protection of the area that needs to be protected above the working plane of the cutting machine equipment; when the operator needs to debug the cutting machine equipment and other operations, the telescopic cylinder is driven to retract the piston rod to make the upper guard plate drop vertically to expose the protection area around the cutting machine equipment, thereby facilitating the operator to debug the cutting machine equipment and other operations. In summary, through the above-mentioned structural design, this protection mechanism can not only ensure the safety of the operator, but also will not interfere with the operator's operation.

[0007] As the core technical concept of the present utility model, the guide mechanism includes a vertically arranged guide rod and a guide block slidably arranged thereon, wherein the guide rod is gapped with and connected to the upper guard plate, and the guide block is provided with a second mounting seat that can be connected to the main body of the pipe cutting machine. When the present protection mechanism is used on the cutting machine equipment, a guide block is slidably arranged on the guide rod, and the guide block is connected to the second mounting seat, which is in turn connected to the main body of the pipe cutting machine, thereby forming a stable guide structure. Compared with only the first mounting seat being connected to the main body of the pipe cutting machine, the guide mechanism and the upper guard plate and the second mounting seat are connected to the main body of the pipe cutting machine. The connection area between the bed bodies improves the stability of the upper guard plate during the lifting process, and the guide block can be set at any height of the second mounting seat according to actual needs. At the same time, since the guide rod is connected to the upper guard plate, the vertical height dimension of the guide rod can be designed according to the vertical height dimension of the upper guard plate. Therefore, after the guide rod is connected to the upper guard plate, the connection area between the guide rod and the upper guard plate can be increased by designing a sufficiently long guide rod, thereby increasing the strength of the upper guard plate. Such a design makes the upper guard plate more stable during the lifting process, thereby improving the guiding effect of the upper guard plate and increasing its safety.

[0008] As a further implementation:

[0009] The protection mechanism is also provided with a lower guard plate, which is vertically arranged on one side of the upper guard plate, and one side of the lower guard plate is also provided with a support seat that can be connected to the main bed of the pipe cutting machine. When the upper guard plate rises above the working plane on the side of the main bed of the pipe cutting machine that needs to be safely protected, the outer side of the main bed of the pipe cutting machine can be protected by the lower guard plate, thereby providing more comprehensive protection for operators and pedestrians, further improving safety.

[0010] To further improve the overall stability and security of this protection mechanism:

[0011] The support seat includes a support rod arranged on the lower side of the upper guard plate. The upper guard plate is configured to be able to be lowered to abut against the support rod so as to support the upper guard plate when the telescopic cylinder fails under special circumstances to prevent damage to other components.

[0012] A connecting rod connected to one side surface of the lower guard plate is vertically provided at one end of the support rod. The length of the connecting rod is not less than 80% of the vertical height of the lower guard plate to increase the connection area between the connecting rod and the lower guard plate, thereby increasing the strength of the lower guard plate. Such a design makes the connection between the lower guard plate and the cutting machine body more stable, thereby increasing the overall safety of the protection mechanism.

[0013] The length of the guide rod is not less than 90% of the vertical height of the upper guard plate, which increases the connection area between the guide rod and the upper guard plate, thereby increasing the strength of the upper guard plate. This design makes the connection between the lower guard plate and the cutting machine body more stable, thereby increasing the overall safety of the protection mechanism.

[0014] There are several groups of telescopic mechanisms arranged with lateral gaps. Usually, the bed of the pipe cutting machine is relatively long. Designing several groups of telescopic mechanisms can evenly divide the force exerted on the upper guard plate when raising and lowering the upper guard plate, thereby making the movement of the upper guard plate more stable and safer.

[0015] There are several support seats arranged in transverse gaps. Designing several support seats can increase the connection area between the lower guard plate and the main bed of the pipe cutting machine, thereby making the connection of the lower guard plate more stable.

[0016] In order to facilitate the operator to observe the cutting machine equipment, a number of transparent observation windows are provided in the middle of the upper guard plate, so that the operator can observe the cutting machine equipment through the transparent observation windows under the protection of the upper guard plate.

[0017] The utility model also provides a laser tube cutting machine, comprising a tube cutting machine body and the above-mentioned tube cutting machine protection mechanism arranged on the outer side thereof.

[0018] To ensure that the upper guard plate has sufficient travel, lower the height of the second mounting seat:

[0019] The second mounting seat includes a vertically arranged long strip, whose cross-section is U-shaped, and connecting plates are vertically arranged on both sides of the opening, the lower end of the connecting plate is connected to the bed of the pipe cutting machine body, and the guide block is connected to the upper end of the long strip. By optimizing the structural design of the second mounting seat, the overall height of the long strip is reduced while maintaining sufficient connection area between the long strip and the upper guard plate and between the guide block and the cutting machine bed, without exceeding the working plane too much, thereby facilitating the operator to debug the cutting machine equipment.

[0020] Preferably, the horizontal height difference between the upper end of the long board and the working plane of the pipe cutting machine body does not exceed 25 cm. According to ergonomic dimensions, the lowest working plane height that usually requires greater strength is 75 cm, while the highest height for adults to work manually is 100 cm. Therefore, the upper end of the long board is designed to be low enough so that the maximum height difference between it and the working plane of the pipe cutting machine body is kept within 25 cm. Such a design not only meets the working comfort of the operator, but also avoids interference with debugging and other work.

[0021] The beneficial effects of the utility model are:

[0022] 1. The upper guard plate and one side thereof are designed with a telescopic mechanism that can drive it to rise and fall in the vertical direction and a guiding mechanism that can provide a guiding effect for its rise and fall, so that the protection mechanism can protect the area above the working plane of the cutting machine when the upper guard plate rises, and at the same time, it is convenient for the operator to debug the parts on the working plane of the cutting machine when the upper guard plate falls;

[0023] Second, through the special connection method and structural design of the guide rod and the guide block in the guide mechanism, the upper guard plate is more stable during the lifting process, thereby improving the guiding effect of the upper guard plate and making it safer.

[0030] like Figure 2 As shown, this embodiment provides a protection mechanism for the pipe cutting machine body 1 (protection mechanism), which is usually arranged on the front side panel of the bed of the pipe cutting machine body 1, and can be used to protect the front side of the bed of the pipe cutting machine body 1 when the pipe cutting machine body 1 processes pipes.

[0031] Combination Figure 1 The protection mechanism includes an upper guard plate 2 and a lower guard plate 3 which are sequentially arranged on the front side plate surface of the bed of the pipe cutting machine main body 1. The upper guard plate 2 and the lower guard plate 3 are both vertically arranged, wherein the upper guard plate 2 is used for protecting the area above the front working plane of the bed of the pipe cutting machine main body 1, and the lower guard plate 3 is used for protecting the area directly in front of the bed plate surface of the pipe cutting machine main body 1.

[0032] For the connection structure between the upper guard plate 2 and the pipe cutting machine body 1, Figure 1 and Figure 2 Specifically:

[0033] A plurality of transparent observation windows are provided in the middle of the upper guard plate 2 so that the operator can observe the cutting machine equipment through the transparent observation windows under the protection of the upper guard plate 2 .

[0034] The rear side of the upper guard plate 2 is provided with a telescopic mechanism capable of driving it to rise and fall in the vertical direction, and a guide mechanism 5 capable of providing a guiding function for its rising and falling.

[0035] Combination Figure 1 Specifically, the structures of the telescopic mechanism and the guide mechanism 5 are as follows:

[0036] Several groups of telescopic mechanisms are arranged along the lateral gap of the upper guard plate 2. Since the bed of the pipe cutting machine body 1 is relatively long, several groups of telescopic mechanisms are designed to evenly divide the force exerted on the upper guard plate 2 when it is raised and lowered, thereby making the movement of the upper guard plate 2 smoother and safer.

[0037] The telescopic mechanism includes a vertically arranged telescopic cylinder 4, which adopts a pneumatic cylinder, and its upper end output part and lower end fixed part are respectively connected to a first mounting seat, and are respectively connected to the upper end rear side plate surface of the upper guard plate 2 and the front side plate surface of the bed of the pipe cutting machine body 1 through the first mounting seats, and the two first mounting seats are connected to the corresponding upper guard plate 2 and the bed of the pipe cutting machine body 1 through bolts.

[0038] The guide mechanism 5 includes a vertically arranged guide rod 51 and a guide block 52 slidably arranged thereon. The guide rod 51 is a cylindrical slide rail with rubber limit blocks at both ends. The guide block 52 is provided with a second mounting seat 6 that can be connected to the bed of the pipe cutting machine body 1.

[0039] A gap is set between the cylindrical slide rail and the upper guard plate 2 and the cylindrical slide rail is connected to the upper guard plate 2, and the length of the cylindrical slide rail is not less than 90% of the vertical height of the upper guard plate 2, so as to increase the connection area between the cylindrical slide rail and the upper guard plate 2, thereby increasing the strength of the upper guard plate 2, making the connection between the lower guard plate 3 and the cutting machine bed more stable, thereby increasing the overall safety of the protection mechanism.

[0040] When the present protection mechanism is used on a cutting machine, a guide block 52 is provided on the sliding cylindrical slide rail, and the guide block 52 is connected to the second mounting seat 6, and the second mounting seat 6 is further connected to the bed of the pipe cutting machine body 1. By increasing the connection area between the guide mechanism 5 and the upper guard plate 2 and the bed, the stability of the upper guard plate 2 during the lifting process is improved, so that a stable guide structure is formed, and the guide block 52 can be set at any height of the second mounting seat 6 according to actual needs. At the same time, since the cylindrical slide rail is connected to the upper guard plate 2, the vertical height dimension of the cylindrical slide rail can be designed according to the vertical height dimension of the upper guard plate 2. Therefore, after the cylindrical slide rail is connected to the upper guard plate 2, the connection area between the cylindrical slide rail and the upper guard plate 2 can be increased by designing a sufficiently long cylindrical slide rail, thereby increasing the strength of the upper guard plate 2. Such a design makes the upper guard plate 2 more stable during the lifting process, thereby improving the guiding effect of the upper guard plate 2 and having higher safety.

[0041] For the connection structure between the lower guard plate 3 and the pipe cutting machine body 1, Figure 1 and Figure 3 Specifically:

[0042] The rear side of the lower guard plate 3 is connected to the bed of the pipe cutting machine body 1 through a support seat 7, and a number of support seats 7 are arranged along the lateral gap of the lower guard plate 3. The several support seats 7 can increase the connection area between the lower guard plate 3 and the bed of the pipe cutting machine body 1, thereby making the connection of the lower guard plate 3 more stable.

[0043] Combination Figure 3 The support seat 7 includes a support rod 71 arranged on the lower side of the upper guard plate 2, and a connecting rod 72 vertically arranged at the front end of the support rod 71 and connected to the front side plate surface of the lower guard plate 3. The length of the connecting rod 72 is not less than 80% of the vertical height of the lower guard plate 3, so as to increase the connection area between the connecting rod 72 and the lower guard plate 3, thereby increasing the strength of the lower guard plate 3, making the connection between the lower guard plate 3 and the cutting machine body more stable, so that the overall safety of the protection mechanism is higher.

[0044] In special circumstances when the cylinder fails, the upper guard plate 2 can be lowered to abut against the support rod 71, and the upper guard plate 2 is supported by the support rod 71 to prevent damage to other components, for example, the cylindrical slide rail falls out of the guide block 52, causing the limit block to be damaged by impact.

[0045] When the protection mechanism is in use, the cylinder is first driven to extend the piston rod to make the upper guard plate 2 rise vertically to above the working plane on the front side of the bed of the pipe cutting machine main body 1, and during the lifting and lowering process of the upper guard plate 2, the guide mechanism 5 provides guidance for it to ensure the smooth movement of the upper guard plate 2, thereby realizing the protection of the area above the working plane on the front side of the cutting machine bed. At this time, the lower guard plate 3 protects the area directly in front of the bed plate surface of the pipe cutting machine main body 1, and then through the cooperation of the upper guard plate 2 and the lower guard plate 3, the protection of the front side of the bed of the pipe cutting machine main body 1 is realized; when the operator needs to debug the cutting machine equipment and other operations, the cylinder is driven to retract the piston rod to make the upper guard plate 2 drop vertically to expose the area above the working plane on the front side of the cutting machine, thereby facilitating the operator to debug the cutting machine equipment and other operations. The protection mechanism can ensure the safety of the operator without interfering with the operator's operation.

[0046] The utility model also provides a laser tube cutting machine, comprising a tube cutting machine body 1 and the above-mentioned tube cutting machine protection mechanism on the outer side thereof.

[0047] Combination Figure 1 and Figure 2 The second mounting seat 6 includes a vertically arranged long strip 61, whose cross section is U-shaped, and connecting plates 62 are vertically arranged on both sides of the opening, the lower end of the connecting plate 62 is connected to the bed of the pipe cutting machine body 1, and the guide block 52 is connected to the upper end of the long strip 61. By optimizing the structural design of the second mounting seat 6, the overall height of the long strip 61 is reduced while maintaining a sufficient connection area between the long strip 61 and the upper guard plate 2 and between the guide block 52 and the cutting machine bed, without exceeding the working plane too much, so as to facilitate the operator to debug the cutting machine equipment.

[0048] The horizontal height difference between the upper end of the long board 61 and the working plane of the pipe cutting machine body 1 does not exceed 25 cm. According to ergonomic dimensions, the lowest working plane height that usually requires greater strength is 75 cm, while the highest height for adults to work manually is 100 cm. Therefore, the upper end of the long board 61 is designed to be low enough so that the maximum height difference between it and the working plane of the pipe cutting machine body 1 is kept within 25 cm. This design not only meets the working comfort of the operator, but also avoids interference with debugging and other work.
