Description

Technical Field

[0001] The utility model relates to the technical field of pipe reels, and in particular to a pipe reel device for drilling tool processing. Background Art

[0002] Tube reels mainly include metal tube reels and paper tube reels. The main working principles and structural settings of the two are roughly the same. The specific pressure, rotation and other parameters are set through the CNC system, and the tube reeling operation is achieved by using pressure rollers. Drilling tools refer to tools used for drilling holes and other related purposes, mainly including drilling (well drilling) tools and metallurgical furnace drill tools. When processing drill tools, a tube reel is needed to bend the steel used to make the drill tools into parts with a circular cross-section, and then weld the gaps.

[0003] In the prior art, the utility model with the authorization announcement number CN213613478U is named as a pipe rolling device. The patent is provided with a slide groove, a movable plate, a magnetic pole A, and a magnetic pole B. When the pipe is rolled and unloading is required, the pole A and the magnetic pole B are closed by the switch, and the movable plate is moved by the handle to move the movable plate to the inner side of the strip groove, so that the strip block is stuck in the inner side of the limit groove. At this time, the switch of the motor A can be turned on, so that the motor A rotates in the same direction, driving the threaded rod to rotate, and the threaded block moves backward on the surface of the threaded rod. The movement of the threaded block drives the connecting rod to move, and the movement of the connecting rod drives the push ring to move backward on the outer surface of the upper pressure roller to push the rolled plate outward. The utility model can realize horizontal unloading, improve efficiency, and reduce the fastening of the rolled plate to prevent the rolled plate from deforming.

[0004] In the prior art, the utility model with the authorization announcement number CN214516930U is named: a pipe winding device that is easy to disassemble and assemble. In order to facilitate the disassembly and assembly of the upper and lower pressure rollers, the patent fixes the driving member to the upper and lower pressure rollers through the clamping member. When the upper and lower pressure rollers are damaged, it is only necessary to rotate the adjusting screw to adjust the distance between the two clamping plates, thereby releasing the connection between the driving member and the upper and lower pressure rollers. The operation is simple, time-saving and labor-saving, and it is more convenient for maintenance personnel to disassemble and assemble the upper and lower pressure rollers.

[0005] Although the tube rolling device mentioned in the above patent can bend the plate into a tubular workpiece with a circular cross-section, since the three pressure rollers of the above tube rolling device are fixed, the plate can only be rolled into a tubular workpiece with a fixed diameter. When a tubular workpiece with other diameters is to be made, the remaining tube rolling devices need to be replaced, which is inconvenient to use. For this reason, we propose a tube rolling device for drilling tool processing. Utility Model Content

Each reinforcing block 8 is fixedly connected to the base plate 1, and the reinforcing blocks 8 are respectively connected to the base plate 1 and the support plates 201, which can play a role of auxiliary support for the support plates 201, thereby achieving the purpose of enhancing the structural strength of the support plates 201.

[0028] A servo electric cylinder 202 is installed on the upper surface of the two support plates 201, and the output shafts of the two servo electric cylinders 202 penetrate the support plates 201 and are slidably connected to the support plates 201. The output shafts of the two servo electric cylinders 202 are fixedly connected to the fixed plates 203, and the bottom surfaces of the two fixed plates 203 are fixedly connected to the fixed blocks 204, and the two fixed blocks 204 are fixedly connected to the upper pressure roller 205.

[0029] The support plate 201 supports the servo electric cylinder 202 . After the servo electric cylinder 202 is started, its output end is extended and retracted, and can drive the fixed plate 203 to move up and down. The fixed plate 203 drives the upper pressure roller 205 to move up and down through the fixed block 204 .

[0030] The inner walls of the two support plates 201 are rotatably connected to two threaded rods 206 , and the outer surface of each threaded rod 206 is threadedly connected to a slider 207 slidably connected to the support plate 201 , and the slider 207 is rotatably connected to the lower pressure roller 208 .

[0031] Rotating the support plate 201 can drive the slider 207 to slide along the inner wall of the support plate 201 , and the slider 207 drives the lower pressing roller 208 to move, thereby changing the distance between the two lower pressing rollers 208 .

[0034] Example 2

[0035] like Figure 1~Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that the upper surfaces of the two fixed plates 203 are fixedly connected to two symmetrical guide rods 3, the guide rods 3 are slidingly connected to the support plate 201, and the upper surface of each guide rod 3 is fixedly connected to a limiting block 4.

It is also possible to simultaneously rotate the two threaded rods 206 located on the same horizontal line, drive the slider 207 to slide along the inner wall of the support plate 201, and drive the lower pressure roller 208 to move through the slider 207 to change the spacing between the two lower pressure rollers 208, thereby changing the bending degree of the plate workpiece, and finally changing the diameter size of the cross section of the tubular workpiece. The above two methods cooperate with each other, which can make the tube reel device more convenient for bending the plate used to make drilling tools.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
