Description
Technical field
The utility model is related to cold shears equipment technical fields, are specially a kind of direct press type cold shears press-roller device.
Background technology
Cold shears is widely used in metallurgy bar, section bar, compound steel rolling production-line, plays the mesh of material cutting to length
, be production line key equipment.Since cold shears shearing is last procedure of commodity scale, so being sheared through cold shears
The deflection of rear material section precision, flatness and material head directly affects rolled products presentation quality, so as to influence to sell.
As shown in Fig. 2, it is in the prior art Baroclinic rolling device for the cold shears of bar material cutting, cold shears is being sheared
During the bar of different size, backing roll and pressure roller can with the increase of stress and there is a situation where double roller off-centring, and with
The continuous increase of diameter of rod, pressure roller can be protruded more compared with the offset of backing roll.When to bar material cutting, backing roll is not
Dynamic, pressure roller is to both vertically as well as horizontally moving, until material is compressed.But since backing roll does not move, cold shears is being sheared
During the material of different size, the stress point of pressure roller and backing roll is subjected to displacement to horizontal direction, is caused after cold shears is sheared
There are certain flexural deformations in bar section.
The content of the invention
The utility model in order to solve in the prior art be used for rod length fixing Baroclinic pressure roller cold shears, in shear history
The middle double roller off-centring that can occur causes the bar section after shearing to there are problems that flexural deformation, and it is cold to provide a kind of direct press type
Shearing machine press-roller device.
The utility model is achieved by the following technical solution：A kind of direct press type cold shears press-roller device, including cylinder
And stop collar, the fixing end of cylinder are connected with cold shears main body, the expansion end of cylinder is hinged with L-shaped connecting rod, connecting rod
The other end is connected with the upper end of movable roll shaft, and connecting rod is hinged with fixed frame in its corner position, and fixed frame is fixed on cold shears owner
On body, stop collar is provided in the middle part of movable roll shaft, the lower part of movable roll shaft is provided with pipe spreader, and movable roll shaft extends vertically through limit
The lower end of position set and pipe spreader and movable roll shaft is connected with pressure roller, the supporting being provided in cold shears main body immediately below pressure roller
Roller.
Axle sleeve tube outer surface is being connected with the auxiliary pressing plate of L-shaped setting towards the direction on the inside of pressure roller, aids in pressing plate bag
Horizontal segment and vertical section are included, vertical section is fixed in cold shears main body.Wherein, position can be adjusted up and down by aiding in the vertical section of pressing plate
It puts.In use, determine auxiliary vertical range of the pressing plate horizontal segment away from backing roll, i.e. horizontal segment bottom surface first according to the diameter of bar
Add 1~2mm to backing roll upper end vertical range for the diameter of bar.
The bottom surface absolute altitude of pressing plate horizontal segment is aided in more than pressure roller bottom surface absolute altitude and the two difference is between 1~2 mm.
During bar material cutting, due to pressure roller less than auxiliary pressing plate, pressure roller prior to auxiliary pressing plate contacted with bar, with pressure roller continue to
During lower vertical extruding, auxiliary pressing plate is contacted with bar, to one support force effect of bar of shearing, prevents from shearing
Stress tilting phenomenon occurs for bar in journey.
The utility model is simple in structure, design is reasonable, by the way that cold shears structure is optimized, is driven using cylinder
The mode promotion activity roll shaft of connecting rod moves up and down, while adds vertically disposed stop collar and pipe spreader, by movable roll shaft
Motion mode be defined to move vertically, ensure pressure roller and backing roll in shear history without offset so that bar was being sheared
It will not cause bar stock bent because of shear force in journey, further, in device add auxiliary pressing plate, can effectively prevent
The tilting of material head, substantially increases the section impression quality after the work efficiency and bar material cutting of cold shears when pressure roller works.
