Want structure type: first is that whole forge piece, its main feature is that rigid good but processing difficulties, are usually used in compact tensile machine；Second is that C-shaped
Board-like mono-tank, its main feature is that easy to process and machining accuracy is high, but due to heat using the fabricated structure of C-shaped plate and beam
The thickness and width for rolling thick steel plate product (for being processed into C-shaped plate) are restricted, so this structure is usually used in medium-sized stretching
Machine；Third is that being used for the combination beam type head of heavy duty drawframe, its main feature is that head uses the combining form of beam, solves monomer and set
The problems such as standby casting, processing transport；But since heavy duty drawframe carrying causes the stress of beam huge greatly, therefore the combination shape of its beam
Formula is vertical overlaying structure, and resulting greatest problem is can not to stretch to short material.For limiting (refining because of working condition
Steel stove, ingot casting etc.) it is not available stretching-machine and carries out for the production line of multiple length production, can not stretch short material is that its fatal is lacked
Point has seriously affected the operation of whole production line.The maximum problem of large-tonnage, Wide and Thick Slab, heavy duty drawframe is that nothing at present
Method stretches short material, it is either internal and international on all not yet solve this problem.
Utility model content
The purpose of this utility model is to provide a kind of load-carrying surface combination beam, the utility model solves large-tonnage, generous
Plate, heavy duty drawframe can not stretch the technical problem of short material.The utility model has the beneficial effects that reducing heavy duty drawframe machine
Head parts of Casting and the difficulty of processing transport, realize the stretching of large-tonnage, Wide and Thick Slab, heavy duty drawframe to short material.
Technical solution used by the utility model is that upper beam and lower beam are attached by several big pulling force columns, is used
To bear the component that drawing force generates along the vertical direction, short transverse positioning is carried out to it with supporting block, by big pulling force column
Apply prestressing force to reduce the shedding deformation of upper beam and lower beam；The inside of upper beam and lower beam forms the sky with inclined-plane
Chamber, upper guide groove are mounted on the inclined-plane inside upper beam, and upper jaw driving device connects upper jaw, the connection of lower jaw driving device
Lower jaw, upper jaw driving device drive several upper jaws to be slided along upper guide groove；Lower guide channel is mounted on inside lower beam
On inclined-plane, lower jaw driving device drives several lower jaws to be slided along lower guide channel, and upper and lower two groups of jaws simultaneously operation is with reality
Existing clamping and release of the head to stretched part；Upper button beam and lower button beam are attached by small pulling force column, in upper inclined wedge connection
Crossbeam and upper button beam, lower inclined wedge connection lower beam and lower button beam, respectively with inclined wedge and lower inclined wedge to upper beam and upper button beam, under
Crossbeam and lower button beam carry out positioning and the compression of draw direction, so as to form upper and lower two load-carrying surfaces to bear drawing force.
