Drill rod machining wire cutting machine

Abstract

The utility model provides a drill rod machining wire cutting machine which comprises a tensioning mechanism, and the tensioning mechanism comprises a base, a sliding block and a guide wheel. The base is provided with a sliding groove separated by a partition plate in the axial direction. The sliding blocks are slidably connected with the sliding grooves, and compression springs are arranged between the sliding blocks and the partition plates. The guide wheel is rotationally connected with the sliding block; the compression spring can enable the two sliding blocks to be far away from each other so as to increase the movement trend of the length of a tangent line between the two guide wheels. The elastic thrust of the compression spring enables the two guide wheels to generate a movement trend of being far away from each other, so that the looseness of the tangent line is compensated, and the tension of the tangent line can be kept constant.

[0028] In order to make the purpose, technical solutions and advantages of this application clearer, the application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0029] In related technologies, wire cutting machines are often used in the processing of drill rods. In order to control the tightness of the tangent, the wire cutting machine is equipped with a tensioning mechanism. The traditional weight-type tensioning mechanism controls the tightness of the tangent by adding or subtracting gravity blocks. However, this control method is not convenient for maintaining constant tangent tension.

[0030] An embodiment of the present application provides a wire cutting machine for processing drill rods, the tensioning mechanism of which can maintain constant tangent tension.

[0031] See also Figure 1-Figure 2In this embodiment, a drill rod processing wire cutting machine includes a tensioning mechanism, which includes a base 10, a slider 20 and a guide wheel 30; wherein, the base 10 has a slide groove 11 axially divided by a partition 12; the slider 20 is slidably connected to the slide groove 11, and a compression spring 21 is provided between the slider 20 and the partition 12; the guide wheel 30 is rotatably connected to the slider 20; the compression spring 21 can cause the two sliders 20 to move away from each other to increase the length of the tangent between the two guide wheels 30.

[0032] The tensioning mechanism utilizes the elastic thrust of the compression spring 21 to cause the two guide wheels 30 to move away from each other, thereby compensating for the looseness of the tangent and maintaining a constant tangent tension.

[0033] It should be noted that the base 10 defines a slide groove 11 extending along its length direction. The slide groove 11 is constructed into a circular shape along the cross section. The slide groove 11 forms a notch 16 on the front side surface of the base 10, and the notch 16 extends along the axis of the slide groove 11. The partition 12 is arranged inside the slide groove 11. The partition 12 divides the slide groove 11 into two symmetrical parts along the axial direction. The partition 12 is arranged perpendicular to the axis of the slide groove 11 as a whole. Circular grooves 14 are provided on both sides of the partition 12, and the grooves 14 are coaxially arranged with the slide groove 11. The grooves 14 are symmetrically arranged on both sides of the partition 12. Sealing plates 13 are screwed on both ends of the slide groove 11. A limiting portion 15 extending along its axial direction is also provided on the inner wall of the slide groove 11. The limiting portions 15 are symmetrically arranged on both sides of the partition 12.

[0034] In addition, the slider 20 is constructed as a whole into a cylindrical shape that is adapted to the slide groove 11. The outer wall of the slider 20 fits into the inner wall of the slide groove 11. The slider 20 is coaxially arranged with the slide groove 11. The slider 20 can move along the axial direction of the slide groove 11. A limiting groove (not shown in the figure) that is engaged with the limiting portion 15 is provided on the outer wall of the slider 20. The limiting groove extends along the axial direction of the slider 20. At the same time, a circular receiving cavity (not shown in the figure) is provided on the end face of the slider 20 opposite to the groove 14. The receiving cavity is coaxially arranged with the slider 20. One end of the compression spring 21 extends into and is engaged with the inside of the receiving cavity, and the other end extends into and is engaged with the inside of the groove 14. The cooperation between the groove 14 and the receiving cavity is used to prevent the compression spring 21 from moving out of the inside of the slide groove 11. The blocking plates 13 at both ends of the slide groove 11 are used to prevent the slider 20 from moving out of the inside of the slide groove 11.

[0035] It should be noted that the width of the notch 16 is smaller than the outer diameter of the slider 20 , so as to prevent the slider 20 from moving out of the slide groove 11 at the notch 16 .

[0036] In addition, the guide wheel 30 is rotatably mounted on the slider 20 . The guide wheel 30 is arranged as a whole on the outside of the base 10 and located on the front side of the base 10 . The axis of the guide wheel 30 remains perpendicular to the axis of the slider 20 .

[0037] In use, the base 10 is first installed on a wire cutting machine, and then the cutting wire 40 is wound from below the two guide wheels 30, when the cutting wire 40 is loose, the compression spring 21 pushes the sliding block 20 and the guide wheel 30 to move outward, thereby increasing the length L of the cutting wire between the two guide wheels 30, so as to keep the tension of the cutting wire constant.

[0038] Although the embodiments of the present application have been shown and described above, it should be understood by those skilled in the art that the above embodiments are exemplary and cannot be construed as limiting the present application, and those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present application.
