Abstract
The utility model discloses a kind of pinch roll apparatus, its objective is to improve performance, reducing production cost.This pinch roll apparatus is made up of clamp system and transmission mechanism two part, and wherein clamp system comprises cylinder, hinge, lever, V-arrangement running roller, promotes two hinges move by cylinder, drives lever respectively around A, B spot wobble, by V-arrangement running roller clamping pipe; Transmission mechanism comprises motor, worm gear, worm screw, large and small gear, adopts motor to drive worm screw, worm gear wheel, drives two to identical gear wheel and pinion rotation, and a pair V-arrangement running roller is rotated, thus pipe is clamped sends forward.The features such as clamping force is large owing to having for pinch roll apparatus, compact conformation, easy for installation, low cost of manufacture are the renewal products of existing pinch mechanism on cold pilger mill.
Description
Technical field
The utility model relates to the pay-off on a kind of cold pilger mill, particularly relates to the pinch roll apparatus on a kind of cold pilger mill.
Background technology
Pinch roll apparatus on existing cold pilger mill is as shown in Figure 1: it be by two identical gears 3 respectively with lever 2, fork 6 is fastening, promote lever 2 by oil cylinder 1 to swing, drive fork 6 synchronous hunting by gear 3 simultaneously, pipe 7 is clamped by running roller 4, a pair V-arrangement running roller 4 is promoted by two cycloidal-pin wheel reducing motors respectively, pipe 7 is clamped and sends forward, in order to realize cold pilger mill continuous rolling then necessary feeding in continuous material (or claiming feeding), the pinch roll apparatus quantity be so arranged on the lathe bed centre position of cold pilger mill determines according to the length of pipe, general need fill six pinch roll apparatus and just can satisfy the demands.This device is owing to directly promoting by oil cylinder, and clamping force is little, and needs two motors to drive two pinch roll apparatus, then a cold pilger mill needs 12 motors to drive.Cause number of motors many, high in cost of production defect, must Curve guide impeller be carried out, to reduce production cost, improve performance.
Summary of the invention
The purpose of this utility model to provide a kind of novel pinch roll apparatus, to improve performance, reduces production cost.
The utility model pinch roll apparatus is made up of clamp system and transmission mechanism, wherein clamp system comprises cylinder, hinge, lever, V-arrangement running roller, here hinge one end links with cylinder, and the hinge other end links with lever, and the other end of lever links with V-arrangement running roller; Transmission mechanism comprises motor, worm gear, worm screw, gear wheel, pinion, here motor is linked with worm gear and worm screw by bearing and axle, two pairs of identical gear wheels and pinion engages each other and by a gear wheel and worm gear fixed-link, pinion links with running roller.All the other parts of pinch roll apparatus and interconnected relationship same as the prior art or similar.
Compared with prior art, its major advantage is the pinch roll apparatus designed and produced according to technique scheme:
1, have employed force-increasing mechanism, clamping force is large, and cylinder instead of oil cylinder;
2, changing vertical is horizontal installation, and centering is good, easy for installation, good looking appearance;
3, adjust the rotating speed of oil motor, just can carry out stepless speed regulation to the speed of pinching;
4, eliminate 12 cycloidal-pin wheel reducing motors, save cost;
5, the hydraulic system of this equipment taken from by the pressure oil of oil motor, separately need not add power, save the energy.
Accompanying drawing explanation
Fig. 1 is pinch roll mechanism schematic diagram in prior art.
Fig. 2 is the transmission mechanism schematic diagram of the utility model pinch roll apparatus.
Fig. 3 is the top view of Fig. 2.
Detailed description of the invention
Below in conjunction with drawings and Examples, pinch roll apparatus of the present utility model is further described.
As shown in Figure 2 and Figure 3, pinch roll apparatus is made up of clamp system and transmission mechanism two part, wherein clamp system comprises cylinder 27, hinge 28, lever 29, V-arrangement running roller 26, here hinge one end links with cylinder, the other end of hinge links with lever, and the other end of lever links with V-arrangement running roller; Transmission mechanism comprises motor 21, worm screw 22, worm gear 23, gear wheel 24, pinion 25, wherein motor 21 is linked with worm gear and worm screw by bearing and axle, two pairs of identical gear wheels and pinion engages each other and by a gear wheel 24 and worm gear 23 fixed-link, pinion 25 links with running roller 26.When working by the pinch roll apparatus of said structure composition, cylinder 27 promotes two hinges 28 and moves, and drives two levers 29 respectively around A, B spot wobble, clamps pipe by V-arrangement running roller 26.Transmission mechanism comprises oil motor 21, worm screw 22 and worm gear 23 and rotates, and drives two to rotate (wherein gear wheel 24 and worm gear fixed-link) identical gear wheel 24 and pinion 25, a pair V-arrangement running roller 26 is rotated, thus pipe 7 is clamped sends forward.Because pipe is longer during enforcement, generally need six pinch roll apparatus to work simultaneously, adopt five connecting axles 20 that the worm shaft of six pinch roll apparatus is concatenated for this reason, need only the V-arrangement running roller of all clamping and conveying devices just can be driven to rotate by an oil motor like this.The utility model pinch roll apparatus has that clamping force is large, compact conformation, easy for installation, low cost and other advantages, is the renewal product of existing clamping and conveying device on cold pilger mill.
