Abstract
The invention relates to a combined pre-tightening type transverse beam structure of a heavy type press. The combined pre-tightening type transverse beam structure is characterized by comprising a middle beam and side beams which are fixedly connected with the two sides of the middle beam, wherein the middle beam and the two side beams are fixedly connected by pull rods and lock nuts to form a whole body; the connected binding surfaces of the middle beam and the two side beams are fixedly provided with positioning keys which are used for guaranteeing the rigidity coordination of the middle beam and the two side beams under load, and guaranteeing the undertaking capability of the middle beam and the two side beams to a shearing inner force caused by deformation. The combined pre-tightening type transverse beam structure has the advantages that the middle beam and the two side beams adopt a steel plate welding structure and are fixedly connected by the pull rods and the lock nuts to form the whole body; the connected binding surfaces of the middle beam and the two side beams are fixedly provided with the horizontal positioning keys and vertical positioning keys which are used for guaranteeing the rigidity coordination of the middle beam and the two side beams under load, and guaranteeing the undertaking capability of the middle beam and the two side beams to a shearing inner force caused by deformation, so that the compact binding of all the beams can be guaranteed, and furthermore, the overall precision and rigidity of a transverse beam are guaranteed. Compared with a traditional casting transverse beam, the combined pre-tightening type transverse beam structure has light weight and low production cost, and is convenient to transport and mount.
Description
Technical field
The invention belongs to metal forming machinery technical field, particularly relate to a kind of heavy press combination prefastening beam structure.
Background technology
At present, entablature and the Lower Crossbeam Structure of ten thousand tons of heavy press adopt casting structure substantially, and casting structure crossbeam overall weight is heavy and manufacturing cost is relatively high.In order to reduce the manufacturing cost of crossbeam, crossbeam is all adopted welded-steel plate construction by some producers, and its piece weight is up to 500 tons.Simple from welding procedure angle, piece weight is not the barrier manufactured, but owing to being subject to processing the restriction of producer self elevating capacity and transport capacity, the crossbeam that result in welded-steel plate construction makes difficulty, therefore need one to be convenient to manufacture, reduce manufacturing cost, and the piece weight not by transport capacity restriction controls within 200 tons, adopts the beam structure of splicing form.
Summary of the invention
The present invention provides a kind of and alleviates crossbeam weight, is convenient to manufacture, reduces costs and be convenient to the heavy press combination prefastening beam structure that transports for solving in known technology the technical problem that exists.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is:
Heavy press combination prefastening beam structure, comprise intermediate beam and the curb girder affixed with its both sides, described intermediate beam and two curb girders are fastened as a whole by pull bar, locknut, are fixed with for ensureing that intermediate beam and two curb girders rigidity are under load coordinated and can bear the positioning key being out of shape and causing and shear internal force at the binding face place that intermediate beam connects with two curb girders.
The present invention can also adopt following technical scheme:
Described intermediate beam and two curb girders all adopt welded-steel plate construction.
Described positioning key is avoid the located lateral key of intermediate beam and two curb girder binding face horizontal direction displacements and the longitudinal register key of vertical direction displacement.
The advantage that the present invention has and good effect are: because the present invention adopts technique scheme, and namely intermediate beam and two curb girders adopt welded-steel plate construction, and are fastened as a whole by pull bar, locknut.Be fixed with for ensureing that intermediate beam and two curb girders rigidity are under load coordinated and can bear the located lateral key and longitudinal register key that are out of shape and cause and shear internal force at the binding face place that intermediate beam connects with two curb girders, fitting tightly between each beam can be ensured, and then ensure that crossbeam overall precision and rigidity.Compared with traditional casting crossbeam, not only lightweight, low cost of manufacture, and be convenient to transport and install.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1.
In figure: 1, curb girder; 2, intermediate beam; 3, locknut; 4, pull bar; 5, located lateral key; 6, longitudinal register key; 7, binding face.
Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, heavy press combination prefastening beam structure, comprise intermediate beam 2 and the curb girder 1 affixed with its both sides, described intermediate beam and two curb girders are fastened as a whole by pull bar 4, locknut 3.Be fixed with at binding face 7 place that intermediate beam connects with two curb girders for ensureing that intermediate beam and two curb girders rigidity are under load coordinated and can bear the positioning key being out of shape and causing and shear internal force.
In the present embodiment, described intermediate beam and two curb girders all adopt welded-steel plate construction.
In the present embodiment, described positioning key is the longitudinal register key 6 that the located lateral key 5 of avoiding intermediate beam and two curb girder binding face horizontal directions to misplace and vertical direction misplace.
Intermediate beam and two curb girders of this crossbeam adopt located lateral key 5 and longitudinal register key 6 to carry out being connected and locate, and can ensure that intermediate beam and two curb girders rigidity are under load coordinated, bear owing to being out of shape the inconsistent shearing internal force caused; Pull bar is carried out pretension by pre-clamping tool by intermediate beam and two curb girders, ensures fitting tightly between each beam, and then ensures crossbeam integral rigidity.
In process, intermediate beam and each single-piece of curb girder and overall processing precision are the guarantees of combination crossbeam total quality, for intermediate beam and curb girder binding face flatness, relatively all require very strict with the positioning precision of the perpendicularity of datum level and horizontal stroke, longitudinal register key, it is special that what need to control is that horizontal stroke, longitudinal register key are relative to the contour conforming precision of curb girder and intermediate beam mating part.After crossbeam entire combination is good, gap and size detection to be carried out to the binding face of intermediate beam and curb girder, the mating surface of positioning key, the fit dimension between crossbeam and equipment remaining part, ensure that the precision of Whole Equipment is unaffected.
