Detailed Implementation

[0022] This utility model provides a receiving structure. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0023] Please see Figure 3 This utility model provides a material receiving structure, including a base 1, a movable plate 2 movably mounted on the base 1, a lifting drive 3 for driving the movable plate 2 to rise or fall, a receiving plate 4 with one end face rotatably connected to the upper part of the movable plate 2, and a receiving drive 5 fixed to the movable plate 2 for driving the receiving plate 4 to tilt horizontally or downward; it also includes a lower protective cover 6 and an upper protective plate 7; please refer to [link to relevant documentation]. Figure 1 and Figure 2 The lower protective cover 6 is located below the receiving plate 4 and is used to cover the movable plate 2, the lifting drive component 3 and the receiving drive component 5 inside it; the upper protective plate 7 is fixedly connected to the movable plate 2 and is located above the base 1.

[0024] In practical applications, multiple receiving structures are set in the receiving area of ​​the laser tube cutting machine. Multiple receiving structures are used to support different positions of the tube to meet the receiving or support requirements of tubes of different lengths.

[0025] In actual use, the lifting drive 3 drives the movable plate 2 to move up and down with the pipe, thereby changing the height of the receiving plate 4 relative to the pipe (especially for non-circular pipes). When the pipe needs to be supported, the receiving drive 5 drives the receiving plate 4 to be in a horizontal state, and then the movable plate 2 and the receiving plate 4 move up and down accordingly. When the pipe needs to be unloaded, the receiving drive 5 drives the receiving plate 4 to be in an inclined state, thereby guiding the pipe placed on the receiving plate 4 to the receiving rack for easy unloading and conveying.

[0026] The aforementioned receiving structure, through the lifting drive component 3, enables the movable plate 2 and the receiving plate 4 to move up and down accordingly, thus providing follow-up support; the receiving drive component 5 enables the receiving plate 4 to support the pipe when horizontal and to unload the pipe when tilted downwards; the lower protective cover 6 and the upper protective plate 7, in conjunction with the receiving plate 4, can isolate the laser to the greatest extent possible, thereby protecting the receiving structure from laser damage during the pipe cutting machine's cutting operation.

[0027] Please see Figure 1 and Figure 2 In some embodiments, the width of the lower protective cover 6 is smaller than the width of the receiving plate 4, and the length of the lower protective cover 6 is smaller than the length of the receiving plate 4. That is, the overall size of the lower protective cover 6 is smaller than the size of the receiving plate 4, so that the receiving plate 4 can completely cover the upper part of the lower protective cover 6, thereby ensuring that the movable plate 2, lifting drive 3, receiving drive 5 and other components inside the lower protective cover 6 are not affected by the laser.

[0028] Please see Figure 1 In some embodiments, the lower protective cover 6 includes two side plates 61 symmetrically arranged on the left and right, and a surrounding plate 62 for connecting the front ends of the two side plates 61; the upper part of both side plates 61 is configured as a forward-sloping surface, which is used to provide clearance for the tilting of the receiving plate 4. Specifically, the lower protective cover 6 can be made by bending sheet metal parts, so that the bending point can be seamlessly connected, the manufacturing process is simple, and the manufacturing cost is low. In addition, since the front end of the receiving plate 4 needs to be tilted downward, the upper part of the side plate 61 is designed as a slope accordingly, so as to adapt to the movement trajectory of the receiving plate 4.

[0029] Please see Figure 1In some embodiments, the lower surfaces of both side plates 61 and the surrounding plate 62 are bent to form mounting plates 63, which are used to fix the lower protective cover 6 to the ground. The mounting plates 63 increase the contact area between the lower protective cover 6 and the ground, and facilitate the insertion of expansion bolts into the mounting plates 63 to fix the lower protective cover 6 to the ground. Furthermore, the rear of the lower protective cover 6 has an open structure, facilitating the installation of the receiving structure after the bed is installed. The lower protective cover 6 is inserted from front to back under the receiving plate 4, and then fixed to the ground. Installation is convenient, and the lower protective cover 6 can be removed when maintenance of the receiving structure is required.

[0030] Please see Figure 1 In some embodiments, a side protective plate 8 is provided on the side wall of the receiving plate 4 near the laser cutting assembly, and the side protective plate 8 is located on the outer side of the side plate 61 near the side protective plate 61. As described above, in order to provide downward tilting clearance space for the receiving plate 4, so that there is a gap between the side plate 61 and the receiving plate 4, the side protective plate 8 is provided to further block the laser generated from the laser cutting assembly, thereby further improving the protection effect.

[0031] Please see Figure 1 In some embodiments, the rear side of the side protective plate 8 is provided with an outwardly bent clearance plate 81, which is used to avoid the side wall of the upper protective plate 7 located behind it. As described above, the receiving plate 4 can tilt downward, so when the receiving plate 4 tilts downward, it will simultaneously cause the side protective plate 8 to tilt. Therefore, in order to avoid the side protective plate 8 from touching the outer side wall of the upper protective plate 7, the outwardly bent clearance plate 81 is provided.

[0032] Please see Figure 2 In some embodiments, the base 1 includes multiple vertically arranged square tubes 11, multiple horizontally arranged square tubes 12, and a base plate 13; the multiple horizontal square tubes 12 are used to connect the multiple vertical square tubes 11, and the back of the base plate 13 is fixedly connected to the front of the vertical square tubes 11 and the horizontal square tubes 12. The frame structure composed of the vertical square tubes 11 and the horizontal square tubes 12 can ensure the stability of the base 1, and the base 1 can be made by welding multiple square tubes, which is convenient in terms of material availability, low in manufacturing difficulty, and lightweight.

[0033] Please see Figure 2In some embodiments, multiple sets of vertical square tubes 11 are arranged front and rear. A through hole 111 is provided on the side wall of the rearmost vertical square tube 11, and a waist-shaped mounting hole 112 extending along its height is provided on the back of the rearmost vertical square tube 11. The waist-shaped mounting hole 112 is used to fix the base 1 to the machine bed. The multiple sets of vertical square tubes 11 can change the width of the base 1 in the front-rear direction, making the receiving structure more adaptable to laser processing scenarios. The through hole 111 facilitates the insertion of tools into the square tube and the insertion of screws / bolts into the corresponding waist-shaped mounting hole 112, thus enabling the receiving structure to be installed on the machine bed. The waist-shaped mounting hole 112 allows for fine-tuning of the height position of the receiving structure relative to the machine bed, facilitating installation.

[0034] Please see Figure 2 In some embodiments, the lifting drive component 3 includes a lifting drive motor 31, a transmission gear 32 connected to the output end of the lifting drive motor 31, and a transmission rack 33 disposed on the front side of the base plate 13; the output end of the lifting drive motor 31 passes through the front and rear side walls of the movable plate 2; the transmission rack 33 extends vertically and is disposed on the base plate 13; the transmission gear 32 meshes with the transmission rack 33. In use, when the lifting drive motor 31 rotates in the forward direction, it drives the transmission gear 32 to rotate in the forward direction, and under the guidance of the transmission rack 33, the movable plate 2 and the receiving plate 4 rise synchronously. Conversely, when the lifting drive motor 31 rotates in the reverse direction, it drives the transmission gear 32 to rotate in the reverse direction, and the movable plate 2 and the receiving plate 4 descend synchronously. The above structure has high transmission efficiency and high transmission accuracy.

[0035] Specifically, the lifting drive motor 31 is a servo motor with a brake function, which can prevent the pipe from falling and causing safety hazards when the lifting drive motor 31 suddenly loses power during pipe cutting, support, or material receiving.

[0036] More specifically, in order to improve the stability of the movable plate 2 when it rises or falls, a slider and a slide rail are also provided between the movable plate 2 and the base plate 13.

[0037] Please see Figure 3 In some embodiments, a bracket 9 is fixedly connected to the upper part of the movable plate 2, and a rotating seat 91 is provided on the upper part of the bracket 9. The rotating seat 91 is used for rotatable connection with the end face of the receiving plate 4. The lower surface of the upper protective plate 7 is fixedly connected to the upper surface of the bracket 9. The length of the upper protective plate 7 is greater than the length of the bracket 9. By limiting the lengths of the upper protective plate 7 and the bracket 9, the upper protective plate 7 can cooperate with the receiving plate 4 to cover the entire receiving structure in the protective cavity. The bracket 9 can be used to change the setting position of the rotating seat 91, so that the length of the movable plate 2 can be reduced, achieving weight reduction.

[0038] Please see Figure 3 In some embodiments, the receiving drive 5 is an inclined receiving cylinder. The cylinder body of the receiving cylinder is hinged to the lower part of the movable plate 2 via a first hinge seat 51, and the piston part of the receiving cylinder is hinged to the free end of the lower surface of the receiving plate 4 via a second hinge seat 52. The receiving cylinder rises and falls with the movable plate 2. When the output end is in a fully extended state, the receiving plate 4 is in a horizontal state, used to support the cutting of the pipe or assist in the unloading of the pipe; when the output end is in a fully retracted state, the receiving plate 4 is tilted downwards, used to guide the pipe as it falls into the unloading rack.

[0039] Please see Figure 1 In some embodiments, the receiving plate 4 is provided with a clearance hole extending along its width direction. A bearing seat 41 is provided at each end of the clearance hole, and a heavy-duty roller 42 is rotatably mounted between the two bearing seats 41. The upper part of the heavy-duty roller 42 protrudes from the clearance hole. The clearance hole is used to install the bearing seat 41 and the heavy-duty roller 42. By limiting the height of the heavy-duty roller 42, it supports the pipe cutting process and reduces friction during the axial / lateral movement of large, heavy pipes.

[0040] In summary, this utility model, through the lifting drive component 3, enables the movable plate 2 and the receiving plate 4 to move up and down accordingly, thus achieving follow-up support; the receiving drive component 5 enables the receiving plate 4 to support the pipe when horizontal and to unload the pipe when tilted downward; the lower protective cover 6 and the upper protective plate 7, in conjunction with the receiving plate 4, can isolate the laser to the greatest extent, thereby protecting the receiving structure from laser damage during the pipe cutting machine's cutting operation.
