Description

Technical Field

[0001] The utility model relates to the technical field of thin wire rolling, in particular to a roller gap adjusting and locking device for a thin wire rolling mill. Background Art

[0002] Fine wire rolling is to heat and roll Φ6.5-12mm wire rod into Φ2-4mm fine steel wire. The rolling mill adopts 6-10 horizontal and vertical staggered layout and centralized transmission. The spacing between the frames of the fine wire rolling mill is small, and loopers cannot be set. After each rolling mill is adjusted, the roll gap cannot drift, otherwise steel accumulation accidents will occur. Utility Model Content

[0003] Purpose of the utility model: The purpose of the utility model is to provide a roller gap adjustment and locking device for a filament rolling mill that can lock the adjusting screw rod of the rolling mill to prevent the roller gap from drifting during the rolling process.

[0004] Technical solution: The utility model discloses a roller gap adjustment and locking device for a filament rolling mill, comprising a fixed disk, a locking disk and a locking pin, wherein the fixed disk is mounted on an adjusting screw and fixed on the outside of a rolling mill housing, the fixed disk has a circle of first circular holes, and the angle between adjacent first circular holes is β; the locking disk is mounted on the adjusting screw and has a circle of second circular holes, and the angle between adjacent second circular holes is α; the locking pin is used to be inserted into the circular holes directly facing the fixed disk and the locking disk after the roller gap of the rolling mill is adjusted, so as to prevent the adjusting screw from rotating.

[0005] Furthermore, the angles α and β are not equal.

[0006] Furthermore, according to the roller gap adjustment size requirement, it is set to β-α=0.2~1°.

[0007] Furthermore, β is set to 12-18°.

[0008] Furthermore, α is set to 13-19°.

[0009] Furthermore, the outer end of the adjusting screw is square, the center hole of the locking disk is an adapted square hole, and the locking disk is sleeved on the adjusting screw.

[0010] Furthermore, the fixing plate is fixed to the outside of the rolling mill box by bolts.

[0011] Furthermore, the fixing plate is fixed to the rolling mill housing by four sets of bolts.

[0012] Beneficial effects: Compared with the prior art, the utility model has the following advantages:

[0013] (1) After the roll gap of the rolling mill is adjusted, the locking pin is inserted into the circular hole opposite the fixed plate and the locking plate to prevent the rotation of the adjusting screw, thereby avoiding the drift of the roll gap caused by impact and vibration during the rolling process and preventing the occurrence of steel piling accidents.

[0014] (2) The roller gap adjustment and locking device of the fine wire rolling mill is installed on the outside of the rolling mill box. It has a simple structure, is easy to use and has reliable performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a structural schematic diagram of a roll gap adjustment and locking device of a filament rolling mill;

[0016] Figure 2 It is a schematic diagram of the structure of the fixed disk;

[0017] Figure 3 It is a structural diagram of the locking disk. DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] Attached Figures 1 to 3 The reference numerals in the figures are as follows:

[0020] 1. Fixed plate; 2. Locking plate; 3. Locking pin; 4. Adjusting screw rod; 5. Rolling mill housing.

[0021] like Figure 1 As shown, a roller gap adjustment and locking device for a filament rolling mill comprises a fixed plate 1, a locking plate 2 and a locking pin 3.

[0022] Combination Figure 2 The fixed plate 1 is sleeved on the adjusting screw rod 4 and fixed to the outside of the rolling mill box 5 by four sets of bolts. The fixed plate 1 has a circle of first circular holes, and the angle between adjacent first circular holes is β, which is set to 12-18°.
