Abstract
Description
Technical Field
[0001] The utility model relates to an idle running slot regulating base for a rolling line vertical rolling mill, belonging to the technical field of metallurgy. Background Art
[0002] The bar rolling mill is arranged horizontally and vertically in a staggered manner. During the rolling process, only part of the rolling mill is used because of the rolling process. At this time, the vacant rolling mill needs to be equipped with a movable empty runner to transport the finished steel billets. Since the vertical rolling mill is a suspended rolling mill, when installing the empty runner, it is necessary to first place the runner on the top of the adjustment base, and then connect the adjustment base with the pin cylinder used by the original rolling mill, and then lift it in the air through the lifting cylinder to align it, and finally lock it with the locking cylinder. The adjustment process of the empty running slot adjustment base is relatively complicated, and the installation is time-consuming and labor-intensive. The control limit of the lifting cylinder is located in a harsh environment and is prone to failure, and frequent manual intervention and control are required; high precision requirements make proofreading difficult, the matching tolerance of the original adjustment base pin hole and the pin cylinder is small, and positioning during the insertion process is difficult; the position and size of the locking block must be precise, and the four locking blocks must be in the same plane and must be perpendicular to the reference horizontal plane to ensure that the running slot does not slip during use; the equipment is frequently damaged and difficult to repair. Since the empty running slot and the adjustment base are suspended, the base is prone to deformation and bending during use, and repair is time-consuming and labor-intensive. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a rolling line vertical rolling mill idle running groove adjustment base, to achieve the idle running groove fast centering, reduce labor intensity, and overcome the shortcomings of the prior art.
[0004] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:
[0005] A rolling line vertical rolling mill idle running groove adjustment base includes a base, an adjusting screw, an upper seat, a clamping block and a positioning hole. The base is composed of a lower plate and an upper plate fixedly connected by a vertical rib plate, a positioning hole is opened on the lower plate of the base, and through holes are opened on the upper plate of the base and the bottom of the upper seat; the adjusting screw passes through the through holes of the upper plate and the upper seat to connect the upper seat and the base together through nuts; the clamping blocks are symmetrically arranged on both sides of the upper seat.
[0006] As a preferred solution, the upper seat and the base are vertically connected via an adjusting screw.
[0007] As a preferred solution, the base is horizontally placed on the roller changing trolley through the positioning holes.
[0008] Beneficial effects: Compared with the prior art, the utility model is used to assist in the centering adjustment of the empty groove of the vertical rolling mill. It can be positioned using the positioning hole and then placed horizontally on the roll changing trolley, and fixed after adjusting the height by adjusting the screw, thereby realizing rapid centering of the empty groove. There is no need to use a lifting cylinder to adjust the height of the vertical empty groove, which effectively reduces the adjustment time of the groove and the deformation and damage of the frame caused by the lifting process. The rolling change time can be compressed from 40 minutes to less than 10 minutes, the adjustment and centering time can be reduced by about 30 minutes, and 2 workers can be saved, the frequency of equipment damage can be reduced, and the equipment repair cost and maintenance cost can be reduced.

DETAILED DESCRIPTION
[0016] Example 1: Figure 1As shown, a rolling line vertical rolling mill idle running groove adjustment base includes a base 1, four adjusting screws 2, an upper seat 3, two clamping blocks 4 and two positioning holes 5. The upper seat 3 is used to fix and place the vertical rolling mill idle running groove. The base 1 is composed of a lower plate 6 and an upper plate 7 fixedly connected by a vertical rib plate 8. Two positioning holes 5 are opened on the lower plate 6 of the base 1, and four through holes 9 are opened on the upper plate 7 of the base 1 and the bottom of the upper seat 3, and the opening positions thereof correspond to each other; the four adjusting screws 2 pass through the upper plate 7 and the four through holes 9 of the upper seat 3 respectively, and then the upper seat 3 is vertically connected to the base 1 through four standard M36 nuts. By adjusting the position of the adjusting bolts 2, the height can be flexibly adjusted. After the adjustment is completed, the clamping blocks 4 on both sides of the upper seat 3 are locked to achieve the ultimate purpose of adjusting the vertical rolling mill idle running groove alignment above the base. The four adjusting screws 2 use 8.8 grade standard screws with a diameter of M36. The two clamping blocks 4 are symmetrically arranged on both sides of the upper seat 3 for locking the base. The base 1 is horizontally placed on the roller changing trolley through two positioning holes 5 for positioning, which is different from the suspended hanging of the original device.
[0017] When in use, first fix the empty running groove above the upper seat 3, then horizontally position the base on the roller changing trolley through the positioning hole 5, adjust the running groove by adjusting the screw 2, and finally lock the clamping block 4 to fix it, so as to realize rapid centering of the running groove.
[0018] The technical concept of the utility model: The technical concept of the utility model is based on the consideration that the original empty running trough base has high requirements on the precision of the clamping blocks and locking holes on both sides, and the installation process is time-consuming and labor-intensive. Moreover, since the running trough is suspended and has no support at the bottom, it is entirely locked by the locking steel. During use, the locking position is easily deformed by force. It is necessary to cancel the lifting mechanism link and keep the base adjustable in the up, down, front and back directions. By changing the support method and using the screw adjustment mechanism, the position of the vertical rolling mill can be quickly installed and adjusted when the rolling line is changed.
[0019] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
