Description

Shearing body structure for preventing steel clamping

Technical Field

The utility model relates to the technical field of bar rolling, in particular to a shear body structure for preventing steel from being clamped.

Background

When the rotary flying shear head and tail is used for rolling steel bars at present, the shears are arranged at the two ends of the shear body, the shear body needs to stop immediately after rapidly rotating and shearing in the shearing process, otherwise, the shears at the other end can rotate to the rolled piece to clamp the rolled piece. If one end of the scissors is removed, when steel stacking occurs, the length of the sheared rolling mill is too long to fall from the hole patterns of the scissors body and the guide groove, and the scissors body is blocked on the scissors body, so that the scissors body is damaged. Therefore, we propose a shear body structure for preventing steel from being clamped.

Detailed Description

The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.

Referring to fig. 1-3, the utility model provides a shear body structure for preventing steel from being blocked, which comprises a pipeline 1, wherein a shear body 2 is arranged outside the pipeline 1, a shear 3 is arranged on the upper side of the shear body 2 in a sliding manner, a first cutting edge 4 is arranged at the top of the left side of the shear 3, a small shear 7 is arranged on the lower side of the shear body 2 in a sliding manner, a second cutting edge 8 is arranged at the bottom of the right side of the small shear 7, a plurality of fastening bolts 10 are sleeved on the right side of the shear body 2 in a threaded manner, the shear 3 is used for cutting the head and the tail during normal rolling, the small shear 7 is staggered with a rolled piece, and cannot touch the rolled piece during rotation, so that steel blocking caused by the rolled piece blocking is avoided.

As shown in fig. 2, a first guiding hole is formed in the scissor body 2, a first guiding strip 5 is movably sleeved in the first guiding hole, the first guiding strip 5 is fixedly connected with the scissor 3, and the scissor 3 can move in the first guiding hole through the first guiding strip 5, so that the scissor 3 can be pulled out for replacement and maintenance.

As shown in fig. 2, a second guiding hole is formed in the lower portion of the pipe 1 and is arranged in the scissor body 2, a second guiding strip 9 is movably sleeved in the second guiding hole, the second guiding strip 9 is fixedly connected with the small scissors 7, and the small scissors 7 can move in the second guiding hole through the second guiding strip 9, so that the small scissors 7 can be pulled out for replacement and maintenance.

As shown in fig. 3, the top parts of two sides of the scissor body 2 are fixedly connected with supporting blocks 6, a convex plate is arranged between the two supporting blocks 6 at the top part of the scissor body 2, and the supporting blocks 6 and the convex plate are used for laterally supporting the scissors 3.

As shown in fig. 1, a plurality of bolt holes are formed in the scissor body 2, and a fastening bolt 10 is sleeved in the bolt holes in a threaded manner, an inner hexagon bolt hole is formed in the fastening bolt 10, and the fastening bolt 10 can tightly support and fix the scissors 2 and the small scissors 7.

As shown in fig. 1, the length of the scissors 3 is greater than the length of the scissors 7.

Detailed working principle: during normal shearing, the shear 3 at one end of the rotary flying shear is used, and the small shear 7 at the other end can avoid the rolled piece. When the rotary flying shears shear shears the rolled piece head and tail, the rolled piece cannot be clamped by the rotation inertia. Meanwhile, when the scrap is needed to be sheared under abnormal conditions such as steel stacking and the like, the scrap shearing interlocking device can push out the switcher for 10cm, so that rolled pieces enter the simultaneous working area of the large scissors and the small scissors, and continuous scrap shearing is realized. After the cutting waste is started, the cylinder pushes the guide groove out by 10cm, and the two scissors on the shear body 2 begin to cut waste simultaneously, so that the other end of the scissors can be prevented from clamping the rolled piece due to inertia during normal rolling, and steel piling is caused.

Although the embodiments of the present utility model have been described with reference to the accompanying drawings, the patentees may make various modifications or alterations within the scope of the appended claims, and are intended to be within the scope of the utility model as described in the claims.
