Description

Technical Field

[0001] The utility model belongs to the technical field of rolling mill assembly, in particular to a special tool for facilitating the adjustment of a rolling mill guide base. Background Art

[0002] The high-speed wire rod production line is a professional production line for producing wire rod coils. The billet is rolled into a wire rod product of specified specifications through alternating horizontal and vertical rough rolling, intermediate rolling, pre-finishing rolling and finishing rolling mills. After the finishing mill is cooled by water tank, it enters the wire laying machine to lay wire rod coils. The intermediate rolling area is composed of a two-roll short stress rolling mill. After rough rolling, the billet passes through the steel guide groove and is guided by the guide device into the two-roll short stress rolling mill to continue the subsequent rolling.

[0003] The guide device is composed of a guide base 2 and a guide. The guide base 2 is installed on the cross beam 3 at the inlet and outlet 6 of the short stress rolling mill 1. Figure 1 The main function of the guide device is to guide the rolled material to smoothly enter the hole groove 8 of the rolling mill roll 7 so as to complete continuous rolling. Figure 2 When the first hole slot 8 is used up, it is switched to the second hole slot 8, and so on until all the hole slots 8 are used up. When replacing the hole slot 8, turn the adjustment bolts 9 on both sides of the screw 4, see Figure 3 , the guide base 2 is driven by the lead screw 4 to move left and right, ensuring that the guide device and the hole slot 8 are in the same rolling line, ensuring the smooth production of wire rods. After the offline rolling mill assembles the new roller 7 in the mill assembly area, it is necessary to adjust the guide base 2 from the original seventh hole slot 8 to the first hole slot 8. Because the screw 4 adjustment bolt 9 is limited by the surrounding space, it is laborious to adjust it with an ordinary wrench. Utility Model Content

[0004] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a special tool for facilitating the adjustment of the guide base of the rolling mill.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0006] A special tool for facilitating adjustment of a rolling mill guide base comprises a lead screw, both ends of which are arranged on a mounting seat, the lead screw is threadedly connected to a guide base, both ends of the lead screw extend out of the mounting seat, both ends of the lead screw extending out of the mounting seat are provided with adjustment bolts, and also comprises a sleeve and a bracket, the sleeve is clamped with the adjustment bolt, the end of the sleeve facing away from the adjustment bolt is connected to a hand crank via a rotating shaft, and the rotating shaft is rotatably connected to the bracket.

[0007] Optionally, a bearing seat is provided on the bracket, and the bearing seat is rotatably connected to the rotating shaft via a bearing.

[0008] Optionally, the sleeve is a telescopic sleeve, which includes an inner sleeve and an outer sleeve, the outer sleeve is slidably connected to the inner sleeve, the inner sleeve is connected to the rotating shaft, the outer sleeve is clamped with an adjusting bolt, and a positioning piece is provided on the inner sleeve, and the positioning piece is used to limit the outer sleeve.

[0009] Optionally, the positioning piece includes an elastic card block, a sliding hole is opened on the inner sleeve, and a sliding block is slidably connected in the sliding hole. When the elastic card block is at its original length, the end of the elastic card block extends out of the sliding hole. When the guide base does not need to be adjusted, the elastic card block limits the outer sleeve to a side of the elastic card block close to the rotating shaft; when the guide base needs to be adjusted, the elastic card block limits the outer sleeve to a side of the elastic card block close to the adjusting bolt.

[0010] Optionally, the adjusting bolt is a hexagonal bolt, and the inner cavity of the outer sleeve is in the shape of a hexagonal column matching the hexagonal bolt.

[0011] Optionally, a rotating outer cylinder is provided on the hand-held portion of the hand crank.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model clamps the sleeve on the adjustment bolt. When the hand crank is turned, the rotating shaft rotates to drive the sleeve and the adjustment bolt to rotate, so that the guide base can be easily adjusted, which improves work efficiency. The design of the bracket and the bearing seat improves the stability of the device. In addition, the outer sleeve and the inner sleeve are connected by sliding. After the special tool is placed in the appropriate position, it does not need to be moved. After the outer sleeve is aligned with the adjustment bolt, it can be slid to the outside of the adjustment bolt, and the elastic block can position the outer sleeve. A rotating outer cylinder is set on the outer side wall of the hand-held part of the hand crank. During the rotation process, the rotating outer cylinder can rotate relative to the hand crank, avoiding the adjustment of the angle of the human hand, and the operation is more convenient.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with specific embodiments.

[0021] Example 1

[0022] like Figure 4 As shown,

[0023] A special tool for facilitating adjustment of a rolling mill guide base comprises a lead screw 4 and a mounting base 10, wherein both ends of the lead screw 4 are arranged on the mounting base 10, a guide base 2 is threadedly connected to the lead screw 4, both ends of the lead screw 4 extend out of the mounting base 10, and both ends of the lead screw 4 extending out of the mounting base 10 are provided with adjustment bolts 9. The special tool also comprises a sleeve 11 and a bracket 12, wherein the sleeve 11 is clamped with the adjustment bolt 9, and one end of the sleeve 11 away from the adjustment bolt 9 is connected to a hand crank 13 via a rotating shaft 14, the rotating shaft 14 is rotatably connected to the bracket 12, and a bearing 16 seat 15 is provided on the bracket 12, and the bearing 16 seat 15 is rotatably connected to the rotating shaft 14 via the bearing 16. The adjusting bolt 9 is a hexagonal bolt, and the inner cavity of the sleeve 11 is a hexagonal column that matches the hexagonal bolt. When the hand crank 13 is turned, the rotating shaft 14 drives the sleeve 11 to rotate. The adjusting bolt 9 can be easily driven to rotate by clamping the sleeve 11 with the adjusting bolt 9, thereby realizing the adjustment of the guide base 2. The stability of the device is guaranteed by the support of the bracket 12.

[0024] A rotating outer cylinder 18 is provided on the hand-holding portion of the hand crank 13. When the hand crank 13 is rotated, the rotating outer cylinder 18 can rotate relative to the hand crank 13, thereby avoiding the need to adjust the angle of the hand and making the operation more convenient.

[0025] Example 2

[0026] like Figure 5As shown, the difference between this embodiment and the embodiment 1 is that the sleeve 11 is a telescopic sleeve 11, the telescopic sleeve 11 includes an inner sleeve 112 and an outer sleeve 111, the outer sleeve 111 is slidably connected with the inner sleeve 112, the inner sleeve 112 is connected to the rotating shaft 14, the outer sleeve 111 is clamped with the adjusting bolt 9, and a positioning member is provided on the inner sleeve 112. The positioning member includes an elastic clamping block 17, a sliding hole is provided on the inner sleeve 112, a sliding block is slidably connected in the sliding hole, and the end of the elastic clamping block 17 extends out of the sliding hole when the elastic clamping block 17 is at its original length. When the guide base 2 does not need to be adjusted, the elastic clamping block 17 limits the outer sleeve 111 on the side of the elastic clamping block 17 close to the rotating shaft 14 to prevent the outer sleeve 111 from falling; when the guide base 2 needs to be adjusted, the elastic clamping block 17 limits the outer sleeve 111 on the side of the elastic clamping block 17 close to the adjusting bolt 9 to ensure the clamping of the outer sleeve 111 with the elastic bolt during the rotation process.
