Abstract
The utility model belongs to a wire drawing die for flat steel bars. The wire drawing die for flat steel bars is composed of a die frame, a cover plate, a guide block which is fixed on the lateral plate of a transverse frame, and pressure rollers which are arranged in the die frame. The wire drawing die for flat steel bars is characterized in that the pressure rollers are two pressure rollers which are arranged in parallel; both ends of the roller shaft of each pressure roller are separately sheathed with bearings; the bearings are embedded in bearing sleeves which are matched with the bearings; the bearing sleeves are positioned in the die frame and the cover plate; a gasket is positioned between the bearing sleeves at the lower ends of the two pressure rollers. The utility model is fixed on a wire drawing machine, the dynamic force of the wire drawing machine is used as tractive force, steel bars are pulled, and the pressure rollers are driven to rotate to flatten the steel bars. The distance between the pressure rollers of the utility model is adjusted by the gasket. The distance between the pressure rollers can be easily adjusted. The utility model has the advantages of simple structure and high productive efficiency.
Description
The utility model relates to the wire drawing die, particularly cold-drawn band steel muscle wire drawing die that metal wire drawing forms.
Prior art such as Chinese patent 912132191 described " slave mode steel wire milling train ".The roll stacks that this milling train is made up of three rolls of the Y-shaped layout of nominal angle 120 degree, adjustment piece, three-jaw slide cartridge, hollow shaft, base and the micro-adjusting mechanism of device roll are formed.This milling train can be installed on the wire drawing machine, makes tractive force with existing drawing machine, draws disc, abnormity and non-constant section alternation steel wire.This milling train is as the horizontal bar band steel muscle wire drawing complex structure of band steel wire drawing, particularly bi-steel for building, and the gap of adjusting between the roll is difficult, makes production efficiency not high.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, designs a kind of and wire drawing machine and is used, and is simple in structure, between the pressure roller gap adjustment easy, the cold-drawn band steel muscle wire drawing die that production efficiency is high.
Solution of the present utility model is: cold-drawn band steel muscle wire drawing die is by the mould bases that can be installed on the wire drawing machine, the cover plate of mould bases upper end, the guide pad that is fixed on the mould bases side plate by fixed head constitutes with the pressure roller that is fixed in the mould bases, be characterized in that pressure roller is to be axially perpendicular to two pressure rollers that cover plate is arranged in parallel, the roll shaft two ends of each pressure roller are with a bearing respectively, bearing imbeds in the bearing holder (housing, cover) that cooperates with it, bearing holder (housing, cover) is placed in mould bases and the cover plate, is provided with a pad between the bearing holder (housing, cover) of two pressure roller lower ends.Its course of work is: wire drawing die is fixed on the drawing machine by mould framing plate.To need the steel bar end hammer of wire drawing flat in advance, and pass from the pilot hole of guide pad, steel bar end carries out wire drawing from passing between two pressure rollers to be clamped by the wire drawing machine chuck; During wire drawing machine pulling reinforcing bar, reinforcing bar and pressure roller friction drive two pressure rollers and rotate in the opposite direction, thereby the distortion of extruding reinforcing bar forms band steel.When need drawing the band steel muscle of different sizes, can and between the diaxon bearing sleeve of bottom, increase or the thickness that reduces pad is finished by the bearing holder (housing, cover) of the different sizes of conversion.
In the solution of the present utility model with the perpendicular side plate of fixed head on be provided with the adjusting bolt of pushing down bearing holder (housing, cover) by the side plate precession, the band steel that draws different sizes only need increase or reduce the thickness of pad, bolt is regulated in precession then, and the compression axis bearing sleeve can be finished.The convenient band steel muscle of dialling different size that draws is saved the wire drawing die cost.
The utility model advantage compared with prior art: the utility model is provided with two pressure rollers in mould bases, wire drawing machine pulling reinforcing bar drives the rotation of two pressure rollers reinforcing bar is flattened, between the bearing holder (housing, cover) of two pressure roller lower ends, be provided with pad, the thickness of adjusting pad can be adjusted the gap between the pressure roller, therefore the utility model is simple in structure, the gap adjustment is easy between pressure roller, production efficiency height, band steel muscle that can cold group of different size.
The utility model can further specify in conjunction with the accompanying drawings.
Fig. 1 is the utility model embodiment half sectional view Figure of abstract of holding concurrently;
Fig. 2 is the A-A face cutaway view of Fig. 1.
The utility model embodiment such as Fig. 1, shown in Figure 2, comprise the mould bases 1 that can be fixed on the wire drawing machine, be fixed on the cover plate 2 at mould bases 1 top, be fixed on fixed head 3 on mould bases 1 side plate by bolt 11, the guide pad 4 in tape guide hole 13 is fixed in the middle of the fixed head 3, two axially parallel with fixed head 3 pressure rollers 5 are arranged in mould bases 1 and the cover plate 2, roll shaft 6 two ends of each pressure roller 5 are with bearing 7 respectively, bearing 7 imbeds in the bearing holder (housing, cover) 8 that cooperates with it, bottom end bearing cover 8 contacts with cover plate 2 with the base plate of mould bases 1 respectively with upper shaft bearing sleeve 8, between lower end diaxon bearing sleeve 8, be provided with pad 9, with another side plate of the perpendicular mould bases 1 of fixed head 3 on have one to regulate bolt 10, regulate bolt 10 and can push down bearing holder (housing, cover) 8 from the side plate precession of mould bases 1.Wherein: the screw 12 on the fixed head 3 is a strip, when the axially parallel of its length direction and pressure roller 5, bolt 11 are fixed on mould bases 1 side plate, can regulate the upper and lower position of the relative side plate of fixed head as required.When need changing cold-drawn band steel size in the present embodiment, can unclamp and regulate bolt 10, the thickness of pad 9 is increased or reduce, tighten then and regulate bolt 10, make its lifting axe bearing sleeve 8.For making full use of each roll surface of pressure roller 5, reduce pressure roller 5 wearing and tearing scrappages, can unclamp bolt 11, fixed head 3 is moved relative to the side plate of mould bases 1 is upper and lower, set bolt 11, thereby make the pilot hole 13 of guide pad 4 relative to upper and lower the moving of pressure roller 5 roll surfaces, pass pilot hole 13 reinforcing bar can with each roll surface friction extruding of pressure roller 4.
