Description
Technical field
The utility model relates to a kind of metallurgical equipment, relates in particular to a kind of cold shears.
Background technology
The cooled bar of cold bed carries out shearing manipulation according to the manufacturing technique requirent needs, like crop, back-end crop and cutting to length.The cold shears of open top roll housing in order to guarantee enough rigidity, must cause whole installation weight to strengthen because cutting edge is a cantilever design, and its rigidity is relatively poor, and shearing area is little in the past, and manufacturing cost shows and increases like this.
The utility model content
To the problems referred to above, the purpose of the utility model is to provide a kind of cold shears, has solved opening degree and has caused whole device excessive when big, and efficient reduces; And shear big section with shearing force when big, steel are to the impact of cutting edge system, cause the problem of hanging down in service life of cutting edge.
For achieving the above object; The said a kind of cold shears of the utility model; Comprise housing of the closed top, motor, reduction box, connecting rod, change cutting edge oil cylinder, upper scissor blade device and lower scissor blade device, wherein, said reduction box is fixed on the said frame; Be connected with clutch, flywheel and brake on the high speed gear shaft in the said reduction box, said motor connects the high speed gear shaft of said reduction box through belt; The low-speed gear axle of said reduction box is a bent axle, and an end of said connecting rod connects bent axle, and the other end is connected with the upper scissor blade device, and said lower scissor blade device is fixed on the frame and is in the below of said upper scissor blade device; Said upper scissor blade device is connected respectively and each self-corresponding cutting edge oil cylinder that changes with the lower scissor blade device, and the said cutting edge oil cylinder that changes is fixed on the said frame.
Preferably, said upper scissor blade device and lower scissor blade device are all inner at said housing of the closed top.
Preferably, said upper scissor blade device comprises upper scissor blade slide, upper scissor blade bearing and upper scissor blade, and wherein, said upper scissor blade slide is connected with an end of said connecting rod, and said upper scissor blade bearing is fixed on the upper scissor blade slide, and said upper scissor blade is fixed on the upper scissor blade bearing; Said lower scissor blade device comprises lower scissor blade bearing and lower scissor blade, and wherein, said lower scissor blade bearing is fixed on the frame, and said lower scissor blade is fixed on the lower scissor blade bearing.
Preferably, said clutch and said brake all adopt pneumatic mode.
The beneficial effect of the utility model is:
Through the switching of clutch realize upper scissor blade decline, shear and action such as rising, the impact that cutting system receives is less, has prolonged the service life of cutting edge, cutting system like this; Shearing area is good; Easily be automated, improved work efficiency, reduced cost.In addition, social benefit of the utility model and economic benefit are also more obvious.
Description of drawings
Fig. 1 is the front view of the described cold shears of the utility model;
Fig. 2 is the side view of K direction among Fig. 1;
Fig. 3 is the cutaway view of A-A among Fig. 2.
The specific embodiment
Below in conjunction with Figure of description the utility model is done further description.
Shown in Fig. 1-3; The said a kind of cold shears of the utility model embodiment; Comprise housing of the closed top 3, motor 1, reduction box 7, connecting rod 8, change cutting edge oil cylinder 2, upper scissor blade device and lower scissor blade device, wherein, said reduction box 7 is fixed on the said frame 3; Be connected with clutch 4, flywheel 5 and brake 13 on the high speed gear shaft in the said reduction box 7, said motor 1 connects the high speed gear shaft of said reduction box 7 through belt; The low-speed gear axle of said reduction box 7 is a bent axle, and an end of said connecting rod 8 connects bent axle, and the other end is connected with the upper scissor blade device, and said lower scissor blade device is fixed on the frame 3 and is in the below of said upper scissor blade device; Said upper scissor blade device is connected respectively and each self-corresponding cutting edge oil cylinder 2 that changes with the lower scissor blade device, and the said cutting edge oil cylinder 2 that changes is fixed on the said frame 3.
As the further embodiment of the utility model, said upper scissor blade device and lower scissor blade device be all in said housing of the closed top 3 inside, adopts housing of the closed top, makes the cold shears good rigidly, and opening degree is bigger, and shearing area is big, and shearing quality is good.
Said upper scissor blade device comprises upper scissor blade slide 6, upper scissor blade bearing 9 and upper scissor blade 10; Wherein, Said upper scissor blade slide 6 is connected with an end of said connecting rod 8, and said upper scissor blade bearing 9 is fixed on the upper scissor blade slide 6, and said upper scissor blade 10 is fixed on the upper scissor blade bearing 9; Said lower scissor blade device comprises lower scissor blade bearing 12 and lower scissor blade 11, and wherein, said lower scissor blade bearing 12 is fixed on the frame 3, and said lower scissor blade 11 is fixed on the lower scissor blade bearing 12.
In addition, said clutch 4 all adopts pneumatic mode with said brake 13, saves manpower, embodies the automation theory.
The operation principle of the utility model is:
After bar arrival in a row was waited to cut the position, clutch closed, and through the slow-speed shaft (bent axle) of reduction box, drivening rod descends thereby drive the upper scissor blade slide and the upper scissor blade that are in the extreme higher position, cuts off bar; Upper scissor blade drops to extreme lower position, and at this moment clutch is opened, and leans on the accurate off-position of brake to peak position promptly to be cut, and shear history finishes.The bar of shearing is sent to subsequent processing by roller-way, and in a row the shear history of bar finishes.When coming next row again, repeat above operation and get final product, can realize the automatic continuous operation.
More than; Be merely the preferred embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claim was defined.
