Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutting, and particularly relates to a short pipe receiving rack. Background Art

[0002] After a pipe cutting machine finishes cutting a pipe, generally a receiving rack is used to receive and unload the cut pipe sections to prevent the pipe sections from falling from a high altitude and colliding rigidly to deform. When developing a pipe cutting machine dedicated to cutting short pipe sections, a corresponding receiving rack for specifically receiving short pipe sections needs to be configured. However, the structure of the receiving racks on the market is too large and the manufacturing cost is high. When the receiving rack is set at the unloading position of the pipe cutting machine, the overall length will be too long, which is not suitable for a pipe cutting machine dedicated to cutting short pipe sections.

[0003] It can be seen that the existing technology still needs to be improved. Summary of the Utility Model

[0004] In view of the deficiencies of the above-mentioned existing technology, the purpose of the utility model is to provide a short pipe receiving rack with a compact structure and low manufacturing cost.

Specific implementation manners

[0020] The present utility model provides a short-material receiving rack. To make the purpose, technical solution and effects of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 4 , the present utility model provides a short-material receiving rack, including a first material receiving plate 11, a second material receiving plate 12 hinged to the first material receiving plate 11, a lifting vertical plate 2 fixedly connected to the bottom of the first material receiving plate 11, a rack 67 and a guide rail 31 vertically arranged on the lifting vertical plate 2, and a cylinder 41 arranged on the lifting vertical plate 2. The end of the piston rod of the cylinder 41 is hinged to the second material receiving plate 12 through a joint. A T-shaped support 5 is arranged below the first material receiving plate 11. A slide block 32 slidably connected to the guide rail 31 is arranged on the T-shaped support 5. A lifting drive 6 is arranged on the T-shaped support 5. A gear 66 meshing with the rack 67 is arranged on the output end of the lifting drive 6.

[0022] In practical applications, the T-shaped support 5 is fixed on the side wall of the bottom frame of the pipe cutting machine, so the slider 32 is stationary, and the lifting driver 6 drives the gear 66 to rotate, thereby driving the rack 67 and the lifting vertical plate 2 and the guide rail 31 to move up and down as a whole. Under the limit guidance of the guide rail 31 and the slider 32, it is ensured that the lifting vertical plate 2 maintains a vertical movement direction, thereby driving the first material receiving plate 11 and the second material receiving plate 12 on the lifting vertical plate 2 to move up and down. When the first material receiving plate 11 and the second material receiving plate 12 are in the material receiving state, the first material receiving plate 11 and the second material receiving plate 12 are spliced ​​to form a plane parallel to the horizontal plane. The material receiving plane is arranged in a row. The lifting height of the material receiving plane can be dynamically lifted and lowered according to the data of the pipe or fixed at a suitable height. The optimal material receiving height is that the material receiving plane just supports the bottom of the pipe. The short pipe section cut by the pipe cutting machine falls directly on the second material receiving plate 12 to reduce the collision and impact between the short pipe section and the material receiving frame. Then the cylinder 41 drives the second material receiving plate 12 to flip downward to form an angle with the horizontal plane, so that under the action of gravity, the short pipe section on the second material receiving plate 12 slides downward along the second material receiving plate 12 to the material discharge container, thereby realizing the discharge of the short pipe section.

[0023] Compared with the prior art, the short material connecting rack provided by the utility model is specially used for receiving the short pipe sections. It not only reduces the length of the first material connecting plate 11 and the second material connecting plate 12 to less than 1000 mm, thus reducing the occupied space, but also can be directly fixed on the side wall of the pipe cutting machine through the T-shaped support 5, compactly cooperates with the pipe cutting machine, minimizes the number of parts and components, and saves manufacturing costs.

[0024] In one embodiment, see Figure 3 As shown, the lifting driver 6 includes a reducer 61 and a driving motor 62, the output end of the driving motor 62 is drivingly connected to the input end of the reducer 61, and the gear 66 is arranged on the output end of the reducer 61. By using the driving motor 62 as the driving source, the driving motor 62 automatically controls the components on the lifting vertical plate 2 to move up and down under the control of the control system, and dynamically adjusts the distance between the second receiving plate 12 and the pipe, so that the second receiving plate 12 can avoid the rotation of the short pipe section, and the second receiving plate 12 can also abut against the bottom surface of the short pipe section to receive the pipe after the pipe is cut.

[0025] In another embodiment, see Figure 4As shown, the lifting drive 6 includes a speed reducer 61 and a handwheel 63 connected to the input end of the speed reducer. The gear 66 is disposed on the output end of the speed reducer 61. Compared with using a drive motor 62 as the drive source, it is more energy-efficient and has a lower manufacturing cost. Before production, the staff rotates the handwheel 63 to drive the gear 66 to rotate, thereby driving the components on the lifting vertical plate 2 to move up and down. After adjusting the height of the second receiving plate 12, the handwheel 63 is locked so that the second receiving plate 12 always maintains an appropriate height during pipe cutting (a height that can receive short pipe segments and does not interfere with the rotation of the pipe).

[0026] To prevent the handwheel 63 from rotating on its own, a C-shaped clamp 64 is provided on the lifting vertical plate 2. The transmission shaft of the handwheel 63 passes through the clamping opening of the C-shaped clamp 64, and the C-shaped clamp 64 is controlled by a clamping handle 65 to clamp or release the transmission shaft of the handwheel 63. The clamping and locking operation is simple and convenient.

[0027] Specifically, see Figure 1 and Figure 3 As shown, the T-shaped support 5 includes a mounting plate 51 and a fixing plate 52 that are perpendicular to each other. The mounting plate 51 and the fixing plate 52 are connected by welding. The fixing plate 52 is provided with fixing holes 55, and fixing screws pass through the fixing holes 55 to fix the fixing plate 52 on the side perimeter of the chassis of the pipe cutting machine.

[0028] Since the smoothness of the meshing between the gear 66 and the rack 67 affects the stability of the lifting, the position of the speed reducer is designed to be adjustable. An adjustment plate 73 is provided on the end face of the mounting plate 51 facing the lifting vertical plate 2. The speed reducer 61 is provided with a plurality of first mounting holes. The adjustment plate 73 is provided with connection holes 731 that are the same in number as and correspond one-to-one with the first mounting holes. The mounting plate 51 is provided with first waist-shaped holes that are the same in number as and correspond one-to-one with the connection holes 731. First locking screws sequentially pass through the connection holes 731 and the first waist-shaped holes and are threadedly connected to the first mounting holes. By loosening the first locking screws, the front and rear positions of the adjustment plate 73 can be adjusted. After the adjustment is completed, the first locking screws are locked again.

[0029] For more precise adjustment, two first tightening screws 71 that press against the side of the position adjustment plate 73 are threadedly connected to the fixed plate 52. A first tightening screw 72 that passes through the fixed plate 52 and is threadedly connected to the side of the position adjustment plate 73 is located between the two first tightening screws 71. In the normal state, when the first tightening screws 71 are in the tightened state, the head of the first tightening screw 72 closely abuts against the back surface of the fixed plate 52. First, loosen the first locking screw, and then loosen the first tightening screws 71. Increase or decrease the screwing-in amount of the first tightening screw 72. The first tightening screw 72 plays a guiding role in the movement of the position adjustment plate 73, thereby controlling the distance between the position adjustment plate 73 and the fixed plate 52, and further controlling the meshing degree between the gear 66 and the rack 67. Then, tighten the first tightening screws 71 again so that the first tightening screws 71 can press against the position adjustment plate 73, and the head of the first tightening screw 72 closely abuts against the back surface of the fixed plate 52 again, effectively preventing the first tightening screw 72 from loosening, thereby positioning the position adjustment plate 73. Finally, lock the first locking screw to complete the adjustment of the position adjustment plate 73. The adjustment operation is simple and precise.

[0030] See Figure 1 As shown, a vertical adjustment plate 42 is fixedly provided on the lifting vertical plate 2. The cylinder body part of the cylinder 41 is connected to the adjustment plate 42 through a hinge plate 43. An adjustment block 48 is provided on the adjustment plate 42 above the hinge plate 43. The adjustment block 48 extends in the left-right direction. A second tightening screw 44 for pressing against the top surface of the hinge plate 43 is threadedly connected to the middle of the adjustment block 48. Two second tightening screws 45 that pass through the adjustment block 48 and are threadedly connected to the top surface of the hinge plate 43 are located between the two second tightening screws 44. A plurality of vertically extending second waist-shaped holes 47 are provided on the adjustment plate 42. The hinge plate 43 is provided with second mounting holes 46 that are the same in number as and correspond one-to-one to the second waist-shaped holes 47. The second locking screw passes through the second waist-shaped hole 47 and is threadedly connected to the second mounting hole 46.

[0031] Under normal conditions, when the second tightening screw 44 is in a tightened state, the head of the second tightening screw 45 closely adheres to the top surface of the adjusting block 48. When adjusting the position of the hinge plate 43 on the adjusting plate 42, first loosen the second locking screw, and then loosen the second tightening screw 44. Decrease / increase the screwing-in amount of the second tightening screw 45. The second tightening screw 45 plays a guiding role in the movement of the hinge plate 43, thereby controlling the height of the hinge plate 43, and further adjusting the height of the cylinder 41. Then tighten the second tightening screw 44 again so that the second tightening screw 44 can hold against the hinge plate 43, and the head of the second tightening screw 45 closely adheres to the top surface of the adjusting block 48 again, effectively preventing the second tightening screw 45 from loosening and positioning the position of the cylinder 41. Finally, lock the second locking screw again to complete the adjustment of the position of the cylinder 41 on the hinge plate 43. The adjustment operation is simple and accurate.

[0032] Preferably, a plurality of auxiliary moving rollers arranged along the length direction of the second receiving plate 12 are provided on the second receiving plate 12. The auxiliary moving rollers can significantly reduce the frictional resistance when the short pipe section slides on the second receiving plate 12, enabling the short pipe section to move more smoothly, reducing wear. Using the auxiliary moving rollers can prevent the short pipe section from directly contacting the second receiving plate 12, reducing the risk of the surface of the short pipe section being scratched or damaged, and maintaining the appearance quality of the product.

[0033] Preferably, the T-shaped support 5 further includes an angle plate 53 connecting the reinforcing mounting plate 51 and the fixing plate 52. The addition of the angle plate 53 can significantly improve the structural strength and stability of the T-shaped support 5. Especially when bearing heavy loads or being subjected to vibrations, it can effectively prevent relative displacement or fracture between the mounting plate 51 and the fixing plate 52, ensuring the safety and reliability of the entire short material receiving rack during the working process. Weight-reducing holes 54 are provided on the angle plate 53 and the fixing plate 52. The design of the weight-reducing holes 54 reduces the material usage amount, enabling the total weight of the T-shaped support 5 to be reduced, which has a positive impact on improving the portability of the overall equipment and reducing the transportation cost. The lightweight design also helps to reduce the energy consumption of the equipment during operation.
