Abstract

The utility model relates to a cold-shearing upper blade of a cold-shearing machine, which comprises a cold-shearing upper blade (1). The cold-shearing upper blade is characterized in that the pass heights of the cold-shearing upper blade (1) are arranged on the same oblique line, the obliquity is 1 degree, the height difference between the bottoms of pass grooves at the head and tail ends of the cold-shearing upper blade (1) is 43.21 mm, and the pass aperture width of the cold-shearing upper blade (1) is 30 degrees. Since the pass heights of the cold-shearing upper blade are arranged in the same oblique line, the inclined blade performs shearing from one side of a rolled piece to the other side of the rolled piece during the shearing process, i.e., at one moment of the shearing process, the length of the fractured surface of the rolled piece cut off by the cutting edge is only one part of the fractured surface of the rolled piece, therefore, the shearing force of the cold-shearing machine is greatly reduced, the pass quality of the blade is fully utilized, and the production efficiency is greatly improved. In addition, the pass aperture width of the cold-shearing upper blade is 30 degrees, the transformation of the rolled piece is obviously reduced during the shearing process, and the ovality of the sheared cross section of the rolled piece becomes small.

Description

The cold shears cutter of cold shears

(1) technical field

The utility model relates to a kind of cold shears, is specifically related to a kind of cold shears cutter of cold shears.Belong to the steelmaking equipment technical field.

(2) background technology

Before the utility model was made, the cold shears cutter pass height of cold shears cutter was on the same level straight line, as shown in Figure 1 in the past.The cold shears shearing force is big, and the cold shears load is big, and blade pass quantity can not make full use of.In addition, cold shears cutter pass opening degree in the past is 60 degree, and deformation of rolled wire is big during shearing, and rolled piece shearing section ovality is big.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides the cold shears shearing force cold shears cutter little, the cold shears that deformation of rolled wire is little, rolled piece shearing section ovality is little when shearing.

The purpose of this utility model is achieved in that a kind of cold shears cutter of cold shears, comprise the cold shears cutter, the pass height that it is characterized in that described cold shears cutter is arranged on the same oblique line, gradient is 1 degree, cold shears cutter head and the tail two ends pass bottom land difference in height 43.21mm, the pass opening degree of described cold shears cutter are 30 degree.

The utility model is arranged on the same oblique line by the pass height with the cold shears cutter, tiltedly blade is that one side from rolled piece is to another side shear history gradually in shear history, promptly in shear history in a flash, it only is the part of rolled piece section that cutting edge is cut off rolled piece section length, thereby the cold shears shearing force significantly reduces, blade pass quantity makes full use of, and production efficiency increases substantially.In addition, the utility model cold shears cutter pass opening degree is 30 degree, and deformation of rolled wire obviously reduces during shearing, and rolled piece shearing section ovality diminishes.

(4) description of drawings

Fig. 1 is the Facad structure schematic diagram of cold shears cutter in the past.

Fig. 2 is the Facad structure schematic diagram of the cold shears cutter of the utility model cold shears.

Among the figure: cold shears cutter 1.

(5) specific embodiment

Referring to Fig. 2, the cold shears cutter of the cold shears that the utility model relates to, comprise cold shears cutter 1, the pass height of described cold shears cutter 1 is arranged on the same oblique line, gradient is 1 degree, cold shears cutter 1 head and the tail two ends pass bottom land difference in height 43.21mm, the pass opening degree of cold shears cutter 1 is 30 degree.

Claims (1)

1, a kind of cold shears cutter of cold shears, comprise cold shears cutter (1), the pass height that it is characterized in that described cold shears cutter (1) is arranged on the same oblique line, gradient is 1 degree, cold shears cutter (1) head and the tail two ends pass bottom land difference in height 43.21mm, the pass opening degree of described cold shears cutter (1) are 30 degree.
