Description

The inversion mechanism of forcing press double-moving worktable

Technical field

The present invention relates to a kind of forcing press, particularly a kind of inversion mechanism of forcing press double-moving worktable.

Background technology

Double-moving worktable possesses the feature of quick die change, and when travelling table A shifts out from press base, the travelling table B with new die can stop after fast movement to the top of base and fix with press base.In the process, mould replacing time is very short, and production efficiency is high, is therefore subject to the extensive favor of client, becomes the configuration combination that forcing press is commonly used the most.

Existing forcing press generally adopts movable formula or left-right movable type with the rail of double-moving worktable, although this kind of track structure and operation are simply, but above rail does not focus on the side of forcing press, cause occupying very large space, build to user's factory building and propose more requirement.In addition, because travelling table has certain movement velocity, how on rail, location is obtained accurately also very important.

Summary of the invention

The object of the invention is to, overcome problems of the prior art, provide a kind of inversion mechanism of forcing press double-moving worktable, take up space little, transposition is convenient.

For solving above technical problem, the inversion mechanism of a kind of forcing press double-moving worktable of the present invention, the bottom of travelling table is respectively equipped with can along X to four the X way rollers rolled and four Y directional rolling bodies that can roll along Y-direction, and the lower edge of described Y directional rolling body is higher than described X way roller; The left side of forcing press working region or right side are provided with overall rail, described overall rail is the rectangular frame be connected as a single entity by front rail, rear rail, left rail and right rail, the left and right sides of described front rail and rear rail is respectively to being connected to the short rail of lifting, the short rail of four joint liftings is corresponding with four X way rollers of travelling table respectively, and the below of the short rail of each described lifting is respectively equipped with the outer elevating ram of machine; Four Y directional rolling bodies of travelling table are corresponding with the bight of described left rail and right rail respectively; The short rail of lifting near forcing press working region saves short circuit rail respectively by head and is connected with forcing press working region, the front end of described left rail and right rail is connected to the front side rail forwards extended, and the rear end of described left rail and right rail is connected to the rear side rail rearward extended.

Relative to prior art, the present invention achieves following beneficial effect: normal operating conditions, and travelling table A is positioned at forcing press working region, and travelling table B is positioned on rear side rail, while travelling table A works, mould is installed on travelling table B by operating personnel.When two travelling tables replace, the X way roller of travelling table A saves short circuit rail along head, is elevated short rail, front rail and rear rail transverse shifting, until four X way rollers are all positioned on the short rail of corresponding lifting, because the lower edge of Y directional rolling body is higher than X way roller, so travelling table A is in transverse shifting process, the unsettled and overall rail of Y directional rolling body does not contact; Then the outer elevating ram of machine makes the short rail of lifting decline, until on four of travelling table A Y directional rolling bodies left rail of dropping on overall rail and right rail, then the Y directional rolling body rolls forward of travelling table A makes travelling table A longitudinally move on the rail of front side, and in this process, four X way rollers of travelling table A are positioned at front side rail and the outside of overall rail and unsettled.Then the Y directional rolling body rolls forward of travelling table B makes travelling table B longitudinally move on overall rail, then that the short rail of lifting is risen to is equal with overall rail for machine outer elevating ram, four X way rollers of travelling table B drop on the short rail of corresponding lifting, four Y directional rolling bodies of travelling table B depart from the left rail of overall rail and right rail simultaneously, travelling table B is laterally moved to forcing press working region along first joint short circuit rail by the X way roller of last travelling table B, so completes the transposition of two travelling tables.Rail is positioned at the same side outside working region, T-shaped structure, takes up space as the half of traditional rail, and can realize two travelling table mold exchanges and work non-interference.
