Abstract

The utility model provides a work piece conveying device for a large hydraulic straightener, which is characterized in that two guide rails are arranged oppositely at both sides of a bench of a large straightener. Three carriages which are provided with rollers and can move along the guide rails are arranged on each guide rail, and the carriages can automatically move by a motor speed reducer. The upper end of each carriage is provided with an elevator frame which is provided with a driving roller and a driven roller. The driving roller and driven roller are mutually parallel and are used for turning work pieces. The elevator frame is also provided with the motor speed reducer to drive the driving roller, and the inner sides of the two guide rails are also provided with fixing frames with guide holes. The fixing frame is provided with an elevator frame which is provided with a guide rod and matched with the guide hole, an oil cylinder driving the elevator frame to move up and down and a ground power device. The elevator frame is provided with a V-shaped holding wheel to support the work pieces, and a shaft. The utility model solves the problem that rod materials can move automatically and horizontally and turn in the processing process of the large hydraulic straightener, and the work efficiency is greatly improved; in addition, the utility model also has the advantages of simple structure and easy fabrication.

Description

Large hydraulic straightener Work transfer device

Technical field

The utility model relates to a kind of hydraulic straightening machine that is used for the alignment bar, especially a kind of large hydraulic straightener Work transfer device.

Background technology

Bar alignment before machining is very important, and it not only can reduce cutting output and save steel, increases work efficiency but also can reduce work hours.Metallurgical in recent years and forging industry has certain demand to this kind special plane equipment, but does not domesticly still have a straightener that the manufacturer production manufacturing is specifically designed to the thick school of bar.Traditional straightening technology mainly is to utilize common hydraulic press to carry out the work of alignment bar at present, this just needs great amount of manpower and the action of aid fluid,matching press just can finish, especially the translation of the bar that diameter is bigger when alignment is operated and upset are particularly difficult, therefore efficient is very low, is unfavorable for producing in enormous quantities.

Summary of the invention

The utility model provides a kind of time saving and energy saving, large hydraulic straightener Work transfer device that automaticity is higher for solving the technical problem that exists in the known technology.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

Large hydraulic straightener Work transfer device, by two guide rails that are fixed on straightener workbench both sides and workbench coaxial line, can be along three dollies of each guide rail translation and the motor reducer of roller and driving rolls thereof, be installed in the crane on each dolly and drive the drive unit that crane moves up and down by guide pillars and bushes, packing ring and rubber cushion on each guide pin bushing are installed, being installed in the motor reducer that be used on the crane to overturn workpiece and the active roller that is parallel to each other and return idler and driving active roller thereof rotate forms, it is characterized in that: the drive unit of described each crane is vertical oil cylinder and the pump group that has lifting piston of installing on the dolly in the middle of two guide pillars, and the piston end of oil cylinder is installed in the bottom face of crane; Described each guide rail inboard also is equipped with the fixed mount that both sides have pilot hole, the fixed mount central vertical is installed the oil cylinder that has lifting piston by the ground hydraulic system drive, the piston end of oil cylinder is equipped with both sides and has the crane that mates guide rod with fixed mount two pilot holes, the V-type support roller and the axle thereof of supporting workpiece installed in crane upper end, be equipped with also between crane lower surface and the fixed mount upper surface that two dampings use cushion block and rubber cushion.

The utility model can also adopt following technical measures:

The two bottom sides of described dolly also is equipped with the block that prevents the dolly getaway.

Advantage and the good effect that the utlity model has are: since in the straightener both sides mounting guide rail and three dolly and each drive motors reductors that have upset workpiece roller on guide rail, moving respectively, make workpiece with dolly translation automatically, upset, not only save time but also laborsaving, improved operating efficiency greatly; Because dolly adopts hydraulic lift, can cushion workpiece to a certain extent brings to such an extent that impact when decompression sticks up, because auxiliary V-type support roller at each guide rail installed inside fixed mount and lowering or hoisting gear, the stub material that can make 8m is smoothly by straightener compacting operation interval, be passed on the dolly of outlet aspect, enlarge the alignment range of work of bar; The utility model also has advantage simple in structure, that be easy to make in addition.
