Description
Technical field
The present invention relates to a kind of metallurgical equipment, relate in particular to a kind of 1200t cold shears.
Background technology
The cooled bar of cold bed carries out shearing manipulation according to the manufacturing technique requirent needs, such as 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 cantilever design, and its rigidity is relatively poor, and shearing area is little in the past, and manufacturing cost shows and increases like this.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of 1200t cold shears, solved opening degree and caused whole device excessive when larger, Efficiency Decreasing; And shear larger section and shearing force when larger, steel cause the low problem in service life of cutting edge to the impact of cutting edge system.
For achieving the above object, a kind of cold shears of the present invention, at least 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, the high speed gear shaft in the described reduction box is connected with combined clutch-brake, flywheel successively; Described motor is connected with flywheel by belt; The interior bent axle of low-speed gear axle in the described reduction box and housing of the closed top is connected by shaft coupling; One end of described connecting rod connects bent axle, and the other end is connected with the upper scissor blade device, and described lower scissor blade device is fixed on the frame and is in the below of described upper scissor blade device; Described upper scissor blade device and lower scissor blade device connect and each self-corresponding cutting edge oil cylinder that changes respectively, and the described cutting edge oil cylinder that changes is fixed on the described frame.
Preferably, described bent axle places on the crankshaft bearing seat of dissection type.
Preferably, described upper scissor blade device comprises upper scissor blade slide, upper scissor blade bearing and upper scissor blade, and wherein, described upper scissor blade slide is connected with an end of described connecting rod, and described upper scissor blade bearing is fixed on the upper scissor blade slide, and described upper scissor blade is fixed on the upper scissor blade bearing; Described lower scissor blade device comprises lower scissor blade bearing and lower scissor blade, and wherein, described lower scissor blade bearing is fixed on the frame, and described lower scissor blade is fixed on the lower scissor blade bearing.
Preferably, described combined clutch-brake all adopts hydraulic way.
Beneficial effect of the present invention is:
The present invention realizes the actions such as decline, shearing and rising of upper scissor blade by the switching of clutch, the impact that cutting system is subject to is less, and, the crank axle bearing is dissection type, and is easy to maintenance, prolonged like this service life of cutting edge, cutting system, shearing area is good, easily be automated, improved work efficiency, reduced cost.In addition, Social benefit and economic benefit of the present invention is also more obvious.
Description of drawings
Fig. 1 is the front view of cold shears of the present invention;
Fig. 2 is the top view of cold shears of the present invention.
The specific embodiment
The present invention will be further described below in conjunction with Figure of description.
As depicted in figs. 1 and 2, the described a kind of cold shears of the embodiment of the invention, at least comprise housing of the closed top 6, motor 1, reduction box 4, connecting rod 7, change cutting edge oil cylinder, upper scissor blade device and lower scissor blade device, the high speed gear shaft in the described reduction box is connected with combined clutch-brake 3, flywheel 2 successively; Described motor is connected with flywheel by belt; The interior bent axle 8 of low-speed gear axle in the described reduction box and housing of the closed top is connected by shaft coupling 5, and described bent axle places on the crankshaft bearing seat of dissection type; One end of described connecting rod connects bent axle, and the other end is connected with the upper scissor blade device, and described lower scissor blade device is fixed on the frame and is in the below of described upper scissor blade device; Described upper scissor blade device and lower scissor blade device connect and each self-corresponding cutting edge oil cylinder 14 that changes respectively, and the described cutting edge oil cylinder that changes is fixed on the described frame.
Wherein, described upper scissor blade device and lower scissor blade device are all inner at described housing of the closed top, adopt housing of the closed top, so that the cold shears good rigidly, opening degree is larger, and shearing area is large, and shearing quality is good.Described upper scissor blade device comprises upper scissor blade slide 9, upper scissor blade bearing 10 and upper scissor blade 11, and wherein, described upper scissor blade slide is connected with an end of described connecting rod, and described upper scissor blade bearing is fixed on the upper scissor blade slide, and described upper scissor blade is fixed on the upper scissor blade bearing; Described lower scissor blade device comprises lower scissor blade bearing 13 and lower scissor blade 12, and wherein, described lower scissor blade bearing is fixed on the frame, and described lower scissor blade is fixed on the lower scissor blade bearing.
In addition, described combined clutch-brake all adopts hydraulic way, saves maintenance cost, reduces noise, embodies the automation theory.And described crank axle bearing is dissection type, is convenient to safeguard, reduces cost.
Operation principle of the present invention is:
When bar in a row arrives after cutting the position, clutch closes, and by 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 to peak position namely to be cut, shear history finishes by the accurate off-position of brake.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 continued operation of automation.
Realize the actions such as decline, shearing and rising of upper scissor blade by the switching of clutch, the impact that cutting system is subject to is less, and, the crank axle bearing is dissection type, and is easy to maintenance, prolonged like this service life of cutting edge, cutting system, shearing area is good, easily be automated, improved work efficiency, reduced cost.In addition, Social benefit and economic benefit of the present invention is also more obvious.
More than; be preferred embodiment of the present invention only, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
