Abstract
A stretching unbender chain transmission lifting pin mechanism with guide comprises a hanging bracket, a plug pin cylinder, a compression column, a cross head, a lifting pin, a roller chain, a fixed chain wheel, movable chain wheels, a chain wheel guide rail, a copper sliding plate and a hanging bracket guide rail. The fixed chain wheel is fixed on two sides of the cross head, the two movable chain wheels are mounted on the hanging bracket above the fixed chain wheel through a shaft, one end of the roller chain is fixed on the fixed chain wheel, and the other end of the roller chain bypasses the movable chain wheels and is connected to the lifting pin. The chain wheel guide rail is fixed on the outer side of a fixed pulley, the hanging bracket guide rail is arranged on a stand column of the hanging bracket, the copper sliding plate is arranged on the surface of the hanging bracket guide rail which abuts against the copper sliding plate on the surface of the hanging bracket guide rail. The stretching unbender chain transmission lifting pin mechanism with guide has the advantages that elastic sliding and slipping do not exist in chain transmission, average transmission is stable and accurate, synchronism and work efficiency of lifting pin motion can be improved, deflexion of a piston rod is avoided, service life of a hydraulic cylinder is prolonged, the chain transmission is small in tensile force, and pressure acting on chain wheels is also small.
Description
Technical field
The utility model belongs to technical field of forging and pressing equipment, relates in particular to seven-roll Abramsen machine and carries pin mechanism.
Background technology
Traditional seven-roll Abramsen machine is carried pin mechanism and adopted without cable for transferring power and the motion of leading, and traditional deficiency of carrying pin mechanism is: efficient is very low, skidding easily occurs, and is dangerous large; The proposing pin motion and can not guarantee to be synchronized with the movement of latch cylinder both sides causes in lifting process the both sides hoisting depth different, often promotes very highly on one side, and another side is carried pin and also do not deviate to compress post, makes the adjustment of fixed chuck very inconvenient; Pulley motion is guiding not, in case unbalance stress occurs in carrying the pin motion process, piston rod in hydraulic cylinder can occur slightly to rotate under the effect of fixed pulley, this sealing damage to hydraulic cylinder is larger, in the situation that the serious piston rod that can cause is crooked, affect greatly the service life of hydraulic cylinder.Therefore to carry pin mechanism be this area technical issues that need to address to seven-roll Abramsen machine, to satisfying suitability for industrialized production, improves the operating efficiency of seven-roll Abramsen machine, and tool is of great significance.
Summary of the invention
The purpose of this utility model is to provide a kind of tension straingtening chain transmission of tape guide and carries pin mechanism, to overcome the deficiency of conventional art.
the technical solution of the utility model is: pin mechanism is carried in the tension straingtening chain transmission of tape guide, comprise suspension bracket, the latch cylinder, the compression post, crosshead, carry pin and transmission mechanism, the latch cylinder is fixed on the compression post, crosshead is connected on the latch cylinder, transmission mechanism is connected to crosshead and carries between pin, it is characterized in that described transmission mechanism is chain-drive mechanism, described chain-drive mechanism comprises roller chain, decide sprocket wheel and movable sprocket, decide the both sides that sprocket wheel is fixedly mounted on crosshead for two, fixed pulley is inboard to be connected with crosshead, decide sprocket wheel for two and lay respectively at latch cylinder both sides, two movable sprockets are arranged on the suspension bracket of deciding the sprocket wheel top by axle, roller chain one end is fixed on to be decided on sprocket wheel, the other end is walked around movable sprocket and is connected to and carries on pin, described chain-drive mechanism also comprises guiding mechanism, described guiding mechanism comprises chain wheel track, copper shoe and suspension bracket guide rail, described chain wheel track is fixed on outside fixed pulley, the column of described suspension bracket is provided with the suspension bracket guide rail, the surface of suspension bracket guide rail is provided with copper shoe, chain wheel track and suspension bracket guide rail surface copper shoe against.
Operation principle of the present utility model is: the latch cylinder drives crosshead and decide sprocket wheel and move up and down under power drive, and chain wheel track is moved up and down on suspension bracket guide rail surface copper shoe with deciding sprocket wheel, proposes the pin lifting by chain transmission control.Chain wheel track and suspension bracket guide rail play guide effect.
The tension straingtening chain transmission of tape guide is carried pin mechanism and is mainly used in the motion of tension straingtening machine grip holder and fixes.
The beneficial effects of the utility model are:
1, compare with original wire rope gearing form, the chain transmission does not have Elastic Sliding and skids, and can guarantee average ratios accurately, can effectively improve the operating efficiency of pin mechanism.
2, the tensile force of chain transmission needs is little, thereby the pressure that acts on sprocket shaft is also less.
3, transmission is more accurate, can effectively reduce both sides and put forward the nonsynchronous situation of pin motion, guarantees that carrying pin can in time deviate to compress post.
4, adopt guide frame to make the motion of carrying pin more steady, effectively avoided the deflection of piston rod, effectively improved the service life of hydraulic cylinder.
