[0025] The fixing seat 6 is provided with a second adjustment channel 10 , and the detachable connecting member 3 passes through the second adjustment channel 10 to connect the fixing seat 6 to the base 1 . The detachable connecting member 3 can move vertically in the second adjustment channel 10 .
[0026] The limiting portion 15 is used to limit the position of the guide groove height adjustment nut 9. The guide groove height adjustment nut 9 is always located above the limiting portion 15 and in contact with the limiting portion 15. By rotating the guide groove height adjustment nut 9, the guide groove height adjustment bolt 8 can be driven to move up and down to realize the lifting and lowering of the guide groove 2, that is, the installation height of the guide groove 2 can be adjusted steplessly by rotating the guide groove height adjustment nut 9.
[0027] The detachable connector 3 can be vertically moved in the second adjustment channel 10, so that the connection between the guide slot 2 and the base 1 can be coordinated with the installation height adjustment of the guide slot 2. In this embodiment, the detachable connector 3 includes a guide slot fixing bolt 11 and a guide slot fixing nut 12.
[0028] The guide groove height adjustment seat 4 also includes an indicating portion 14, which is welded to the base 1 and is vertically arranged to the limiting portion 15. A scale 16 is provided on the indicating portion 14, and the position can be adjusted according to the indicated position of the connection between the guide groove height adjustment bolt 8 and the fixing seat 6.
[0029] The ruler 16 is used to accurately indicate the height adjustment distance of the guide groove 2, so as to accurately adjust the height of the guide groove 2 and better control the coincidence of the incoming material center line and the shearing center line. The actual elevation of the guide groove 2 can be marked on the ruler 16 for bar products of different specifications, so as to accurately adjust the elevation of the guide groove 2, improve the multiple scale accuracy and the yield rate, and avoid equipment failure to a certain extent.
[0030] A lateral distance adjusting member 13 is provided on the guide groove fixing bolt 11 between the base 1 and the fixing seat 6, and the guide groove height adjusting bolt 8 can move in the first adjusting channel 5, and the moving direction of the guide groove height adjusting bolt 8 in the first adjusting channel 5 is parallel to the length direction of the guide groove fixing bolt 12. In this embodiment, the lateral distance adjusting member 13 is a gasket, and the thickness of the lateral distance adjusting member 13 can be adjusted by adding or removing gaskets.
[0031] By adjusting the thickness of the lateral distance adjusting piece 13, the lateral position of the guide groove 2 can be adjusted to ensure that after the guide groove device is installed on the multiple-size flying shear equipment, the groove body 7 can be adjusted to be within the width range of the flying shear blade to ensure that the finished product can be sheared through the guidance of the guide groove 2 and the flying shear blade.

[0033] The front end of the trough body 7 is provided with a discharge port, and the side wall of the trough body at the discharge port extends forward to form an extension portion 19. The upper and lower sides of the extension portion 19 are respectively detachably connected with an upper guard plate 17 and a lower guard plate 18. In this embodiment, the upper guard plate 17 and the lower guard plate 18 are detachably connected by bolts.
[0034] Since the finished product is rolled out at a high temperature and high speed, the outlet of the guide groove is prone to wear. By providing an upper guard plate 17 and a lower guard plate 18, only the upper and lower guard plates can be replaced after wear, saving costs.
[0035] The working principle of the guide groove device of this embodiment is as follows:
[0036] When adjusting the height of the guide groove 2, loosen the guide groove fixing nut 12, rotate the guide groove height adjustment nut 9, and drive the guide groove 2 to rise or fall by the guide groove height adjustment bolt 8. Observe the lifting and lowering position of the guide groove 2 according to the indication of the ruler 16. When the guide groove 2 rises or falls to the specified position, tighten the guide groove fixing nut 12 to adjust the height of the guide groove 2.
[0037] When adjusting the lateral distance of the guide groove 2, loosen the guide groove fixing nut 12, add or reduce the lateral distance adjustment piece 13 to the guide groove fixing bolt 11 between the base 1 and the fixing seat 6, and when the lateral distance of the guide groove 2 is adjusted, tighten the guide groove fixing nut 12 to adjust the lateral distance of the guide groove 2.
[0038] Example 2
[0039] This embodiment discloses a multiple-length flying shear, such as Figure 3 , Figure 4 As shown, it includes a flying shear body 20, two sets of flying shear swing arms 21 symmetrically arranged on the same side of the flying shear body 20, and a guide groove device for multiple-size flying shears. The structure of the guide groove device for multiple-size flying shears is the same as that of Example 1, and will not be repeated here. The base 1 is welded to the flying shear body 20 to achieve a stable connection between the guide groove device and the flying shear body 20. The front ends of the two sets of flying shear swing arms 21 are provided with flying shear blades 22 that cooperate with each other. The guide groove 2 is located on the side of the flying shear swing arm 21 of the flying shear body 20, and the discharge port is connected to the flying shear body 20.
[0040] Before the multiple-size flying shear works, the height and lateral distance of the guide groove are adjusted according to the specifications of the product to be sheared, so that the incoming center line of the guide groove 2 coincides with the shearing center line of the flying shear body 20. During operation, the product to be sheared passes through the guide groove device and is cut into a preset size by the flying shear blade 22.
