Abstract

The invention discloses a mechanical disc shearing machine used for shearing a thick steel plate, and belongs to the field of metal plate shearing machines. An upper cutter rest and a lower cutter rest of an existing mechanical disc shearing machine in the prior art are changed to a left and right supporting type from a cantilever type. The mechanical disc shearing machine used for shearing the thick steel plate comprises a disc shearing machine body, a left and right interval adjustment device, an upper cutter rest bearing, a lower cutter rest bearing, an upper cutter rest, a lower cutter rest, an upper cutter rest shaft, a lower cutter rest shaft, an upper supporting frame plate, a lower supporting frame plate, an upper bearing seat, a lower bearing seat, an upper tapered roller bearing and a lower tapered roller bearing. The mechanical disc shearing machine used for shearing the thick steel plate is characterized in that the upper supporting frame plate and the lower supporting frame plate with central shaft holes are connected to the right surface of the machine body through bolts; the upper and lower bearing seats provided with the upper and lower tapered roller bearings are installed in the central shaft holes of the upper and lower supporting frame plates respectively; the right ends of the upper and lower cutter rest shafts are installed in the upper and lower tapered roller bearings respectively, and the left ends of the upper and lower cutter rest shafts are installed in the upper and lower cutter rest bearings respectively. The mechanical disc shearing machine used for shearing the thick steel plate has the advantages of being capable of shearing the steel plate 30-40 mm thick at a time, and improving production efficiency.

Description

A kind of mechanical disk-type cutter for shearing steel plate

Technical field

The invention belongs to metal sheet shearing machine tool technical field, being specifically related to a kind of mechanical disk-type cutter for shearing steel plate.

Background technology

Circle shears is widely used in, in metallurgy industry sheet material finishing, being usually arranged on finishing line, because blade is the disk rotated, and thus can the moving steel plate of longitudinal shear continuously.

The circle shears used both at home and abroad at present mainly contains two types, what the cutterhead of the circle shears of the first type adopted is cantilever structure, as shown in Figure 1, circle shears discontinuity when shearing steel plate of the type, balance is bad, especially shear comparatively steel plate time cutter shaft can there is deflection deformation, the section of steel plate of shearing is caused to there will be inclined plane shape defect, cause the increase of percent defective, therefore the circle shears of the type is mainly applicable to the steel plate that longitudinal shear thickness is less than 20-30 millimeter at present.

What the circle shears of the second type adopted is the mode that two circle shearses are connected mutually sheared steel plate, mainly be applicable to the steel plate that shearing thickness is 30-40 millimeter, its shearing mechanism is the 5%-10% of First circle shears incision steel plate thickness, and then steel plate all cuts off by second circle shears, although this cutting method can shear the steel plate of 30-40 mm of thickness, but equipment investment is large, shear efficiency is low, and because the factors such as the vibration of cutter may cause twice shearing not overlap in actual production, thus cause the raising of percent defective.

Summary of the invention

It is the mechanical disk-type cutter of 30-40 millimeters thick steel plate for shearing thickness that the object of the invention is to provide a kind of, can overcome the shortcoming existed in existing circle shears shearing technique, thus enhance productivity.

The present invention is achieved in that and it is characterized in that the tool axis up and down by old for prior art mechanical disk-type cutter is improved to left and right brace type by cantilevered, and as shown in Figure 2, it includes new body 1 ^,, clearance adjustment apparatus 2,2 between left and right ^,, upper and lower knife rest bearing 3,3 ^,, upper lower slide 4,4 ^,, new tool axis 10,10 up and down ^,, carrier parts plate 6,6 ^,, metal (upper seat 7,7 ^,, upper and lower conical surface taper roll bearing 8,8 ^,and upper and lower labyrinth bush 9,9 ^,, be shaped with upper and lower central shaft hole 11,11 ^,carrier parts plate 6,6 ^,be bolted at new body 1 ^,right flank on, upper and lower conical surface taper roll bearing 8,8 is housed respectively ^,metal (upper seat 7,7 ^,be arranged on carrier parts plate 6,6 respectively ^,central shaft hole 11,11 ^,in; It is provided with lower slide 4,4 ^,tool axis up and down 5,5 ^,right-hand member be arranged on upper and lower conical surface taper roll bearing 8,8 respectively ^,in, its left end is arranged on upper and lower knife rest bearing 3,3 respectively ^,in; Upper and lower conical surface taper roll bearing 8,8 ^,medial surface be separately installed with upper and lower labyrinth bush 9,9 ^,.

Good effect of the present invention is:

1. circle shear of the present invention left end that is upper and lower, lower slide is fixedly mounted on circle shears body respectively by bearing, right-hand member is fixedly mounted on carrier parts respectively by conical surface taper roll bearing, such structure not only can avoid the phenomenon of traditional circle shears cutter shaft generation flexure in shear history because one end supports in shear history, and the structure that two ends support can bear very large shearing force, thus once can shear the steel plate of 30-40 millimeter.

2. the present invention's upper and lower knife rest right-hand member adopts conical surface taper roll bearing to be connected with upper and lower support respectively, for convenience detach, can reduce labor strength, enhance productivity.

3. the front end of the present invention's upper and lower knife rest right-hand member conical surface taper roll bearing adopts the form of labyrinth bush sealing, has sealing reliable, the advantage that structure is simple and easy to use.
