Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a frame assembly for a steel plate laser cutting equipment. Background Technology

[0002] A steel plate cutting platform refers to the platform on which a laser cutting machine places a steel plate. A laser cutting machine focuses a laser emitted from a laser source into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] Laser cutting of steel plates requires the use of support racks, which serve to support the steel plates. However, during the laser cutting process, the support racks may melt due to the laser. In existing technologies, the support racks are fixed to the frame by bolts or other means, making replacement inconvenient.

[0004] Therefore, it is necessary to improve the frame components of existing steel plate laser cutting equipment. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects in the existing technology and provide a frame assembly for a steel plate laser cutting equipment, which facilitates the replacement of the support rack that cannot provide support after melting.

[0006] To achieve the above technical effects, the technical solution of this utility model is as follows: a frame assembly for a steel plate laser cutting equipment, including a frame body, a plurality of crossbeams fixedly arranged inside the frame body, the plurality of crossbeams being spaced apart along the length direction of the frame body, a mounting plate being fixedly arranged between two adjacent crossbeams, the mounting plate being spaced apart along the extension direction of the crossbeams, the mounting plate being provided with a first insertion groove, and the supporting rack being provided with a second insertion groove that is inserted and engaged with the first insertion groove.

[0007] According to one embodiment of the present invention, a baffle plate is fixedly provided on the side wall of the support tooth above the second insertion slot.

[0008] According to one embodiment of the present invention, a support platform is fixedly provided on the side wall of the crossbeam, and the mounting plate is fixed on the support platform.

[0009] According to one embodiment of the present invention, a connecting plate is fixedly disposed on the support platform, the side wall of the mounting plate abuts against the connecting plate, and the mounting plate and the connecting plate are fixedly connected by bolts and nuts.

[0010] According to one embodiment of the present invention, the mounting plate is fixedly provided with a thickening plate, the thickening plate is disposed above the bolt and nut, and the projection of the bolt and nut on the horizontal plane is located within the projection of the thickening plate.

[0011] According to one embodiment of the present invention, an installation strip is fixedly provided on the inner wall of the frame body, and the crossbeam is provided with a groove that is inserted and matched with the installation strip. The end of the crossbeam is abutted against the inner wall of the frame body.

[0012] According to one embodiment of the present invention, the end of the supporting rack is disposed in contact with the inner wall of the mounting strip or the inner wall of the frame body.

[0013] According to one embodiment of the present invention, a refractory brick mounting bracket is provided above the crossbeam, and the refractory brick mounting bracket is provided with a limiting wall that abuts against the side wall of the crossbeam.

[0014] According to one embodiment of the present invention, the refractory brick mounting bracket is clamped between two adjacent thickened plates.

[0015] The advantages and beneficial effects of this utility model are as follows: The frame component of the steel plate laser cutting equipment of this utility model is reasonably designed. By setting crossbeams in the frame body and setting mounting plates between two adjacent crossbeams, the support rack is inserted and matched with the mounting plate.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0019] like Figure 1-9 As shown, the steel plate laser cutting equipment frame assembly of the embodiment includes a frame body 1. A plurality of crossbeams 2 are fixedly arranged inside the frame body 1. The plurality of crossbeams 2 are spaced apart along the length direction of the frame body 1. A mounting plate 3 is fixedly arranged between two adjacent crossbeams 2. A plurality of mounting plates 3 are spaced apart along the extension direction of the crossbeams 2. The mounting plate 3 is provided with a first insertion groove 31. The supporting rack 4 is provided with a second insertion groove 41 that is inserted and engaged with the first insertion groove 31.

[0020] This design significantly simplifies the replacement process of the support rack and improves efficiency: the support rack uses its own second insertion slot to form an insertion fit with the first insertion slot of the mounting plate, instead of the traditional bolt fixing method. When the support rack melts due to laser cutting and can no longer support the steel plate, there is no need to remove bolts or other fasteners; the support rack can be replaced directly by insertion and removal, avoiding cumbersome disassembly and assembly steps, significantly shortening replacement time, and improving equipment maintenance and continuous operation efficiency.

[0021] Ensuring the stability of the frame components and improving cutting accuracy: Several crossbeams are spaced along the length of the frame body, and multiple mounting plates are fixed at intervals between adjacent crossbeams along the extension direction of the crossbeams, forming a uniform and stable support structure foundation. The mounting plates, as the mounting carriers for the support racks, ensure a more regular installation position for the support racks, thereby making the support racks provide more uniform and stable support for the steel plate, reducing the shaking of the steel plate during laser cutting, and ensuring cutting accuracy.

[0022] According to one embodiment of the present invention, a baffle plate 42 is fixedly provided on the side wall of the support tooth above the second insertion slot 41.

[0023] This design avoids the molten rack from affecting the interlocking structure and ensures smooth replacement of the support rack: During laser cutting, molten metal is generated. The baffle plate 42 is fixed on the side wall of the support tooth above the second interlocking groove 41, which can directly prevent the molten metal from falling into the second interlocking groove 41.

[0024] According to one embodiment of the present invention, a support platform 21 is fixedly provided on the side wall of the crossbeam 2, and the mounting plate 3 is fixed on the support platform 21.

[0025] This design enhances the stability of the mounting plate and prevents the support rack from wobbling: the support platform 21 is a special support structure extending from the side wall of the crossbeam 2. After the mounting plate 3 is fixed on the support platform 21, it is not easy to shift, tilt or loosen due to the pressure of the steel plate borne by the subsequent support rack 4. This ensures that the support rack 4 is always in a stable installation state, and avoids the steel plate being unstable due to the shaking of the mounting plate during the laser cutting process, which would affect the cutting accuracy.

[0026] According to one embodiment of the present invention, a connecting plate 22 is fixedly provided on the support platform 21, and the side wall of the mounting plate 3 abuts against the connecting plate 22. The mounting plate 3 and the connecting plate 22 are fixedly connected by bolts and nuts.

[0027] This design provides double-fixation to prevent displacement and ensure the long-term stability of the mounting plate: the connecting plate 22 provides additional lateral support for the mounting plate 3—the mounting plate 3 is not only fixed to the support platform 21 at the bottom, but its sidewalls also abut tightly against the connecting plate 22. Combined with the tightening action of bolts and nuts, this creates a triple-fixation effect of "bottom support + lateral limiting + bolt locking." This design effectively prevents the mounting plate 3 from shifting or tilting laterally during long-term use due to the pressure of the steel plate supported by the rack 4 or vibrations during laser cutting, ensuring that the mounting plate remains in the preset installation position and providing a prerequisite for the stable assembly of the rack.

[0028] With a clear positioning reference, the assembly efficiency and regularity of the mounting plate are improved: the connecting plate 22 can serve as the "lateral positioning reference" for the mounting plate 3. During installation, the lateral position of the mounting plate can be quickly determined simply by abutting the side wall of the mounting plate 3 against the connecting plate 22, without the need for repeated adjustments and alignment, which greatly improves the assembly efficiency.

[0029] According to one embodiment of the present invention, the mounting plate 3 is fixedly provided with a thickening plate 32, the thickening plate 32 is disposed above the bolt and nut, and the projection of the bolt and nut on the horizontal plane is located within the projection of the thickening plate 32.

[0030] This design isolates the bolts and nuts from laser cutting, ensuring convenient maintenance and preventing any impact on them.

[0031] According to one embodiment of the present invention, an installation strip 11 is fixedly provided on the inner wall of the frame body 1, and a groove 23 is provided on the crossbeam 2 to be inserted and engaged with the installation strip 11. The end of the crossbeam 2 is abutted against the inner wall of the frame body 1.

[0032] This design ensures the stability of the beam connection.

[0033] According to one embodiment of the present invention, the end of the support rack 4 is abutted against the inner wall of the mounting strip 11 or the inner wall of the frame body 1.

[0034] This design enables rapid and precise positioning, ensuring the regularity of the support rack arrangement: the abutment structure provides a clear "end reference" for the installation of the support rack—during installation, simply push the end of the support rack until it fits against the mounting strip or the inner wall of the frame body to quickly determine the lateral installation position of the support rack, eliminating the need for repeated measurements and adjustments. This positioning method ensures that the ends of all support racks in the same area are aligned, avoiding messy arrangement of support racks due to installation position offset, thus ensuring a uniform distribution of support points for the steel plate and reducing slight tilting of the steel plate due to uneven support.

[0035] Limiting end displacement and enhancing the stability of the support rack under stress: During laser cutting, the weight of the steel plate and vibrations during the cutting process exert lateral forces on the support rack. If the ends of the support rack are unrestrained, slight displacements can easily occur over long-term use, leading to support position deviation and uneven support force. The end abutment can limit the support rack laterally, preventing end displacement under stress or vibration, keeping the support rack in the preset support position, ensuring stable and reliable support for the steel plate, and guaranteeing the stable positioning of the steel plate during laser cutting.

[0036] According to one embodiment of the present invention, a refractory brick mounting bracket 5 is provided above the crossbeam 2, and the refractory brick mounting bracket 5 is provided with a limiting wall 51 that abuts against the side wall of the crossbeam 2.

[0037] This design allows for quick and precise positioning of the mounting bracket, improving assembly efficiency and regularity. The contact and fit between the limiting wall 51 and the side wall of the crossbeam 2 provide a clear lateral positioning reference for the refractory brick mounting bracket 5. The refractory bricks inside the mounting bracket also protect the crossbeam.

[0038] Limiting the displacement of the mounting frame ensures the stability of the high-temperature protection function of the refractory bricks. High-temperature radiation is generated during laser cutting, and the refractory bricks need to accurately cover key components such as beams to isolate them from the high temperature and prevent the frame components from being damaged by high temperature.

[0039] According to one embodiment of the present invention, the refractory brick mounting bracket 5 is clamped between two adjacent thickened plates 32.

[0040] With this design, the refractory brick mounting bracket is precisely positioned on the thickened plate 32 and fixed on the mounting plate 3 by using the regular spacing of the thickened plate. The existing structure is reused without additional parts, simplifying the assembly process. The original function of the thickened plate 32 is to protect the bolts and nuts. In this case, it is also used as the limiting structure of the refractory brick mounting bracket. There is no need to design or add special limiting blocks, buckles or other parts for the mounting bracket.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
