Description

Technical Field

[0001] This utility model relates to the field of blanking technology for laser cutting machines, and more specifically, to a blanking guide structure for laser cutting machines. Background Technology

[0002] Thick plates have a relatively wide range of applications, are easy and reliable to process and weld, and can save a lot of material and processing costs. Therefore, the equipment issues in the thick plate cutting process have attracted much attention. Existing thick plate laser cutting equipment mainly consists of laser cutting components, cutting platform, bed and unloading guide structure. Due to the large weight of thick plates, hoisting equipment is needed to place the thick plates on the cutting platform. The thick plates are then cut by the laser cutting components. Smaller materials or waste generated during cutting will fall from the gaps in the cutting platform for collection or discharge.

[0003] However, currently, the material guide structure is installed on the support structure of the bed by a number of screws. The installation position is low and the distance from the initial material dropping height is high, which can easily cause structural damage and is not easy to replace, making the installation difficult. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a blanking guide structure for a laser cutting machine, which solves the problem that the blanking guide structure is currently installed on the support structure of the machine bed by a number of screws, and the installation position is low, the distance from the initial blanking height is high, which easily causes structural damage, is not easy to replace, and has a high installation difficulty.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a material guide structure for a laser cutting machine, including a bed connecting pipe, a bed table support fixedly installed on the bed connecting pipe, and a material guide component fitted onto the bed connecting pipe through the bed table support;

[0006] The material unloading guide assembly includes a base plate with a slot at its bottom. The base plate can be fitted onto the bed connecting pipe through the slot. The base plate has a first support through hole, which allows it to be fitted onto the bed table support. Side support plates are welded to both the front and rear sides of the base plate. A material unloading guide plate is provided at the top of the side support plates. The material unloading guide plate has a second support through hole, which allows it to be fitted onto the bed table support.

[0007] Preferably, the bed surface support, the first support hole, and the second support hole are configured as corresponding rectangular structures.

[0008] Preferably, the bottom support plate and the side support vertical plate are welded together to form an H-shaped structure, and the material drop guide plate is formed to form a pointed structure.

[0009] Preferably, a side support inclined plate is provided at the top of the side support vertical plate, and a number of supporting ribs are uniformly welded at the angle between the side support vertical plate and the side support inclined plate. The two side support inclined plates are parallel to the front and rear sides of the material drop guide plate, respectively.

[0010] Preferably, there are two material guide components, which are stacked sequentially in the vertical direction supported by the bed table.

[0011] Preferably, the lower material guide component has a larger structural dimension than the upper material guide component.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model allows the bottom support plate and the material drop guide plate to be fitted onto the bed table support from top to bottom through the first support through hole and the second support through hole, thus completing the installation. This structure can be stably placed on the bed without the need for screws, achieving the functions of material drop guidance and bed protection.

[0014] This utility model uses a bed table support, a first support through hole, and a second support through hole to form a corresponding rectangular structure, which can restrict the rotational movement of the bottom support plate and the unloading guide plate around the bed table support, ensuring that the preset angle and orientation are always maintained after assembly, enhancing the overall rigidity. At the same time, it can quickly perform pre-positioning and improve assembly efficiency.

[0015] This utility model, through the setting of side bracing inclined plates and supporting stiffeners, utilizes the geometric stability of triangles and the force transmission advantages of surface contact to enhance the connection rigidity of side bracing vertical plates and side bracing inclined plates, resisting the pressure deformation caused by the falling of thick plate materials or waste materials.

[0016] This invention shortens the single drop height of materials or waste by setting up a double-layer material guide component, breaking down the original large impact into two small impacts, realizing the step-by-step absorption of energy, reducing the damage to the structure from the source, and ultimately extending the service life of the laser cutting machine.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 3This utility model provides a material guide structure for a laser cutting machine, including a bed connecting pipe 1, a bed table support 2 fixedly mounted on the bed connecting pipe 1, and a material guide assembly 3 fitted onto the bed connecting pipe 1 via the bed table support 2. The material guide assembly 3 includes a bottom support plate 31, with a slot 32 at the bottom of the bottom support plate 31, allowing the bottom support plate 31 to be fitted onto the bed connecting pipe 1 via the slot 32. The bottom support plate 31 also has a first support through hole 33, allowing the bottom support plate 31 to be fitted onto the bed table support 2 via the first support through hole 33. Side support plates 34 are welded to both the front and rear sides of the base plate 31. A material drop guide plate 36 is provided on the top of the side support plates 34. The material drop guide plate 36 has a second support through hole 37. The material drop guide plate 36 can be fitted onto the bed table support 2 through the second support through hole 37. The base plate 31 and the material drop guide plate 36 are fitted onto the bed table support 2 from top to bottom using the first support through hole 33 and the second support through hole 37 to complete the installation. This structure can be stably placed on the bed without the need for screws, realizing material drop guidance and bed protection. The machine tool features a bed connecting pipe 1 and a bed table support 2, which are internal support structures for the laser cutting machine bed, used to support the cutting platform. The unloading guide plate 36 serves as a guide for unloading. The bed table support 2, the first support through hole 33, and the second support through hole 37 are set as corresponding rectangular structures, which can restrict the rotational movement of the bottom support plate 31 and the unloading guide plate 36 around the bed table support 2, ensuring that they always maintain the preset angle and orientation after assembly, enhancing overall rigidity. At the same time, it can quickly perform pre-positioning, improving assembly efficiency. The bottom support plate 31 and the side support vertical plate 34... After welding, it is set in an H-shaped structure. The material guide plate 36 is set in a pointed structure. The top of the side support vertical plate 34 is set with a side support inclined plate 35. Several supporting ribs 38 are evenly welded at the angle between the side support vertical plate 34 and the side support inclined plate 35. By setting the side support inclined plate 35 and the supporting ribs 38, the geometric stability of the triangle and the force transmission advantage of the surface contact can be utilized to enhance the connection rigidity of the side support vertical plate 34 and the side support inclined plate 35, and resist the pressure deformation caused by the falling of thick plate materials or waste materials. The two side support inclined plates 35 are parallel to the front and rear sides of the material guide plate 36, respectively.

[0024] Further embodiments, such as Figure 1 , Figure 2 As shown, there are two material guide components 3. The two material guide components 3 are stacked in sequence in the vertical direction of the bed table support 2. The material guide component 3 located below has a larger structural size than the material guide component 3 located above.

[0025] Specifically, when materials and waste fall from the gap of the cutting platform, their impact force is essentially the instantaneous force generated by the collision of gravitational potential energy into kinetic energy and the material guide component 3. The magnitude of the impact force is directly related to the "falling height" and the "mass of materials and waste". When the height difference between the cutting platform and the ground is large, the kinetic energy of the materials and waste before landing is extremely large. A single impact will cause a violent impact on the material guide component 3. The double-layer material guide component 3 reduces the single falling height, breaking down the original large impact into two small impacts, realizing the step-by-step absorption of energy, reducing the damage to the structure from the source, and ultimately extending the service life of the laser cutting machine. When the two material guide components 3 are stacked, the bottom support plate 31 located below is fitted on the bed connecting pipe 1 and the bed table support 2, and the top bottom support plate 31 is stacked on the material guide plate 36 and the bed table support 2.

[0026] The working principle of this utility model is as follows:

[0027] During laser cutting, small pieces of material or waste will fall from the gaps in the cutting platform. Using the material guide plate 36 to guide the falling material will improve the service life of the cutting machine and concentrate the falling material, making it easier to handle waste. If there is a large height difference between the cutting platform and the ground, a double-layer material guide assembly 3 can be used. Installation can be completed simply by placing smaller material dropping structures on the material dropping structure in sequence, which can greatly reduce the impact force of falling material and thus improve the service life of the structure.
