Description

Technical Field

[0001] The utility model relates to the field of pipe processing equipment, and particularly relates to a post-saw roller table. Background Art

[0002] The post-saw roller table is located behind the mainframe flying saw. Its main function is to catch the pipes sent by the mainframe. After the flying saw cuts the pipes, the cut fixed-length pipes can quickly separate from the saw blade. Such quick separation has two functions: one is to protect the cutting saw blade from damage, and the other is to ensure that the next pipe will not butt against the first pipe.

[0003] Existing post-saw roller tables can be divided into two categories: center positioning and bottom line positioning according to the mainframe positioning method. The bottom line positioning roller table technology is relatively mature. For the center positioning forming method, according to the pipe diameter range produced by the unit, usually the bottom line height will change to varying degrees. This requires the post-saw roller table to be adjustable in height to solve the problem of different bottom line heights for steel pipes with different diameters produced by the unit. Usually, a section of passively rotatable roller table that can be lifted and lowered independently is selected. After catching the cut fixed-length pipe, it descends to place the fixed-length pipe on the power roller table and quickly send it out, and the passively rotatable roller table rises to catch the next pipe. The lifting and lowering of the roller table usually uses a structure with an oil cylinder or a cylinder driving a hinge, and the problem of different bottom line heights is solved by adjusting the length of the connecting thread between the piston rod of the oil cylinder or the cylinder and the connecting rod. This method has a small adjustment range, can only meet the situation where the pipe diameters are not very different, and the adjustment is relatively troublesome, with high requirements for workers. Content of the Utility Model

[0021] Referring to Figures 1-3 , this embodiment provides a post-saw lifting roller table, including a first frame 11, a second frame 12, and a third frame 13. The first frame 11 is used to install the driving roller 21, and the second frame 12 and the third frame 13 are respectively used to install the first driven roller 22 and the second driven roller 23. It should be noted that in this embodiment, the first frame 11, the second frame 12, and the third frame 13 are on the same straight line.

[0022] It should be noted that although this embodiment adopts the method of one driving roller driving two driven rollers, the protection scope of this embodiment is not limited thereto. Other numbers of driving rollers or driven rollers are also within the protection scope of the present utility model. For example, one driving roller drives three driven rollers or four driven rollers, or two driving rollers drive one driven roller respectively, and these are all within the protection scope of the present utility model.

[0023] In this embodiment, a driving roller 21 is installed on the first frame 11. The driving roller 21 is connected to one end of the first rotating arm 3. The other end of the first rotating arm 3 is rotatably connected to one end of the first connecting rod 4. The other end of the first connecting rod 4 is connected to one end of the second rotating arm 5. The other end of the second rotating arm 5 is connected to the first driven roller 21. The first driven roller 21 is installed on the second frame 12. One end of the first rotating arm 3 connected to the driving wheel 21 is installed on the first frame 11. One end of the first rotating arm 3 connected to the first connecting rod 4 is connected to the piston rod 63 of the oil cylinder 62 through the earring 61.

[0024] In some embodiments, the diameter of the end of the first rotating arm 3 connected to the driving roller 21 is larger than the diameter of the end of the first rotating arm 3 connected to the first connecting rod 4, which is convenient for controlling the center of gravity of the whole device and improving stability.

[0025] During operation, when the driving roller 21 rotates, it drives the first connecting rod 4 to move through the first rotating arm 3, thereby driving the subsequent first driven roller 22 and second driven roller 23 to rotate. The oil cylinder 62 drives the piston rod 63 to move back and forth. The piston rod 63 drives the first rotating arm 3 and the first connecting rod 4 to move through the earring 61. The oil cylinder 62 is fixed on the slider 7. The slider 7 is connected to a slide rail (not shown in the figure). The slider 7 is connected with a driving mechanism. In this embodiment, the driving mechanism includes a motor 81. The output end of the motor 81 is connected to one end of the lead screw 82. The other end of the lead screw 82 is connected to the slider 7 through a flange 83.

[0026] In this embodiment, the extending direction of the slide rail is perpendicular to the axis of the driving roller 21, which can maximize the guarantee of uniform force and improve stability.

[0027] By driving the oil cylinder 61 to slide back and forth through the driving mechanism, the distance between the piston rod 61 and the driven roller is changed, thereby driving the height of the connecting rod relative to the ground, and thus adjusting the height of the driven roller relative to the ground.

[0028] The saw-back lifting roller table provided in this embodiment omits the threaded connecting piece between the piston rod of the oil cylinder and the connecting rod in the past, adds a lift and a slide seat, and adjusts the fixed position of the oil cylinder by adjusting the extending length of the lift lead screw, so as to achieve the purpose of adjusting the height of the driven roller. The operation is simple and easy to adjust, and it can meet the adjustment of the bottom line height when the pipe diameters vary greatly, and achieve a better connection effect with the subsequent roller table.

[0029] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
