Background technique
The important link produced and processed as coloured and ferrous metal is stretched, the mechanical property for improving metal is played
Vital effect.Tension force stretching machine equipment is mainly used for the stretching of coloured or ferrous metal Strip, pipe rod type material etc., leads to
Crossing makes metal generate certain elongation, not only plays the role of certain aligning and leveling to material, it is often more important that change
It has been apt to the stress distribution of metal inside, has improved the mechanical property of material.Head of the stretching-machine for garter extension has several masters
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.
Summary of the invention
The purpose of the present invention is to provide a kind of load-carrying surface combination beam, the present invention solves large-tonnage, Wide and Thick Slab, heavy drawing
The technical problem of short material can not be stretched by stretching machine.The beneficial effects of the invention are as follows reduce heavy duty drawframe head parts of Casting and add
The defeated difficulty of labour movement realizes the stretching of large-tonnage, Wide and Thick Slab, heavy duty drawframe to short material.
The technical scheme adopted by the invention is that upper beam and lower beam are attached by several big pulling force columns, to hold
The component that tension stretch generates along the vertical direction carries out short transverse positioning to it with supporting block, by applying to big pulling force column
Prestressing force is to reduce the shedding deformation of upper beam and lower beam；The inside of upper beam and lower beam forms the cavity with inclined-plane, on
Guide groove is mounted on the inclined-plane inside upper beam, and upper jaw driving device connects upper jaw, the lower pincers of lower jaw driving device connection
Mouthful, upper jaw driving device drives several upper jaws to be slided along upper guide groove；Lower guide channel is mounted on the inclined-plane inside lower beam
On, 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 to realize machine
Clamping and release of the head to stretched part；Upper button beam and lower button beam are attached by small pulling force column, and upper inclined wedge connects upper beam
With 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, lower beam
Positioning and the compression that draw direction is carried out with lower button beam, so as to form upper and lower two load-carrying surfaces to bear drawing force.

Specific embodiment
The present invention is described in detail With reference to embodiment.
The present invention is as shown in Figure 1 to Figure 3, and upper beam 1 and lower beam 4 are attached by several big pulling force columns 5, to hold
The component that tension stretch generates along the vertical direction carries out short transverse positioning to it with supporting block 7, by applying to big pulling force column 5
Prestressing is to reduce the shedding deformation of upper beam 1 and lower beam 4.
The inside of upper beam 1 and lower beam 4 forms the cavity with inclined-plane, and upper guide groove 8 is mounted on the inclined-plane inside upper beam 1
On, upper jaw driving device 11 connects upper jaw 9, and lower jaw driving device 12 connects lower jaw 14, upper jaw driving device 11
Several upper jaws 9 are driven to be slided along upper guide groove 8；Lower guide channel 15 is mounted on the inclined-plane inside lower beam 4, lower jaw driving
Device 12 drives several lower jaws 14 to be slided along lower guide channel 15；Upper and lower two groups of jaws simultaneously operation is to realize head to stretching
The clamping and release of workpiece 16.
Upper button beam 2 and lower button beam 3 are attached by small pulling force column 6, and upper inclined wedge 10 connects upper beam 1 and upper button beam 2, under
Inclined wedge 13 connects lower beam 4 and lower button beam 3, respectively with inclined wedge 10 and lower inclined wedge 13 to upper beam 1 and upper button beam 2, lower beam 4
Positioning and the compression that draw direction is carried out with lower button beam 3, so as to form upper and lower two load-carrying surfaces 17 to bear drawing force.
Upper and lower button beam is mainly used for bearing by stretching the moment of flexure generated, and upper and lower crossbeam is mainly used for bearing drawing force and drawing force institute
The vertical direction component of generation.
Several crossbeams, holding in upper beam 1 and lower beam 4 can be increased at the load-carrying surface 17 of upper button beam 2 and lower button beam 3
Repairing type is carried out at power face 17, to improve its stress distribution, reduces stress concentration phenomenon.
It is also an advantage of the present invention that:
1. the present invention is for large-tonnage, the heavy duty drawframe of Wide and Thick Slab.The head of stretching-machine uses the crossbeam of upper and lower subdivision
And button beam, solve heavy duty drawframe integrated head it is overweight, it is excessive caused by casting, transport etc. difficulties, while can guarantee compared with
High machining accuracy.
2. using the load-carrying surface combination beam type structure of draw direction.Respectively by holding between upper and lower crossbeam and upper and lower button beam
The connection of power face, so that main stretching cylinder acting surface be made to move back, the most short spacing of two heads becomes smaller, and realizes the stretching to short material.
3. optimizing the structure of major part to improve crossbeam and detain the force-bearing situation of beam, stress concentration phenomenon is reduced: (1)
Increase several crossbeams in button Liang Chenglimianchu above and below；(2) correction of the flank shape is carried out to upper, lower horizontal beam load-carrying surface.
The above is only not to make limit in any form to the present invention to better embodiment of the invention
System, any simple modification that embodiment of above is made according to the technical essence of the invention, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
