Because the guide belongs to a vulnerable part, 3-4 sets of guides must be configured for each hole type, and the cost of spare parts is increased; in addition, the production is stopped when the rolling groove is replaced, and the guide is moved to a new rolling groove, so that the disassembly and the assembly of the guide occupy a large amount of time and workload of a rolling mill, and 3-4 persons are required to specially inspect and maintain the guide after each use.
Disclosure of Invention
The invention aims to provide an adjustable guide for a bar mill, which can directly replace a rolling groove and the guide without stopping production, greatly improve the production efficiency and solve the problems in the background technology.
The technical scheme of the invention is as follows:
an adjustable guide and guard for a bar mill is arranged at the inlet or the outlet of the bar mill and comprises a screw rod, a hydraulic motor, a screw rod bearing, a guide wheel seat, a conical bearing, guide wheels and a guide and guard frame, wherein a plurality of pairs of guide wheels which are vertically arranged are arranged in the guide and guard frame according to the rolling direction of a bar, the outer surfaces of the guide wheels are two symmetrical conical surfaces, the diameter of the middle of each guide wheel is smaller than that of each guide wheel, each guide wheel is provided with a guide wheel shaft, two ends of each guide wheel shaft are respectively installed on the guide wheel seats through the conical bearing, the guide wheel seats at two ends of each guide wheel shaft are respectively connected to the screw rod, the screw rods are arranged in an up-and-down parallel mode, two ends of each screw rod are respectively.
The guide frame is a rectangular frame.
The guide frame is formed by connecting an upper part and a lower part through connecting bolts.
And a cooling water system of the guide wheel is arranged on the guide frame.
And a grease lubrication oil hole leading to the conical bearing is formed in the guide wheel seat.
By adopting the invention, the distance between the two guide wheels is adjusted according to the rolling specification, and when the rolling groove needs to be replaced in the steel rolling process, the screw rod is driven to rotate by the hydraulic motor, so that the two guide wheels are moved to the position opposite to the new rolling groove.
The invention has the beneficial effects that: the rolling groove and the guide can be directly replaced without stopping production, the production efficiency is greatly improved, the spare part cost and the number of personnel are reduced, the production cost is reduced, and the method is suitable for production of bars with multiple specifications.
Drawings
FIG. 1 is a cross-sectional view of the present invention;
FIG. 2 is a front view of the present invention;
FIG. 3 is a top view of the present invention;
in the figure: the guide wheel structure comprises a screw rod 1, a hydraulic motor 2, a connecting bolt 3, a screw rod bearing 4, a guide wheel seat 5, a conical bearing 6, a guide wheel 7, a cooling water system 8, a dry oil lubrication oil injection hole 9, a hole type guide plate 10, a wear-resisting plate 11, a handle 12, steel 13 and a guide frame 14.
Detailed Description
The invention is further illustrated by way of example in the following with reference to the accompanying drawings.
Referring to the attached drawings 1, 2 and 3, an adjustable guide and guard for a bar mill is arranged at an inlet or an outlet of the bar mill and comprises a screw rod 1, a hydraulic motor 2, a screw rod bearing 4, a guide wheel seat 5, a conical bearing 6, a guide wheel 7 and a guide and guard frame 14, wherein a plurality of pairs of guide wheels 7 which are vertically arranged are arranged in the guide and guard frame 14 according to the rolling direction of the bar, the outer surfaces of the guide wheels 7 are two symmetrical conical surfaces, the diameter of the middle of each guide wheel 7 is smaller than that of each end, each guide wheel 7 is provided with a guide wheel shaft, two ends of each guide wheel shaft are respectively installed on the guide wheel seats 5 through the conical bearings 6, the guide wheel seats 5 at two ends of each guide wheel shaft are respectively connected to the screw rod 1, the screw rods 1 are arranged in an up-down parallel manner, two ends of the screw rod 1 are respectively rotatably connected to the guide and guard.
In this embodiment, referring to fig. 2 and 3, an arrow P indicates a rolling direction, two pairs of guide wheels 7 are arranged in the guide frame 14 in front and at the back according to the rolling direction, each pair of guide wheels 7 are respectively arranged on two vertically arranged lead screws 1, and when the hydraulic motor 2 drives the lead screws 1 to rotate, two guide wheel seats 5 on the lead screws 1 simultaneously move in opposite directions, so that the guide wheels 7 are always consistent with a rolling center line.
The outer surface of the guide wheel 7 is two symmetrical conical surfaces, and the diameter in the middle of the guide wheel 7 is smaller than the diameters of the two ends so as to adapt to bars with different specifications.
