Description

Technical Field

[0001] This utility model relates to the field of upper shearing technology, specifically an upper shearing blade for a fixed-length shearing machine in a wire rod production line. Background Technology

[0002] The upper shear blade locking device is widely used in the fixed-length shearing machine of the wire rod production line in the metallurgical industry. It usually acts on the locking part of the shear blade of the shearing device, so that the upper shear blade can be locked easily and quickly. The fixed-length shearing machine is a key piece of equipment in the bar production line. Its function is to cut bars according to a fixed length. The characteristic of this type of shearing machine is that the lower shear blade is stationary, while the upper shear blade moves up and down to complete the shearing action. During the shearing process, the locking mechanism of the upper shear blade plays a crucial role. If the shear blade locking mechanism fails to lock the shear blade, causing the shear blade to loosen, a safety accident will occur. If the locking force of the upper shear blade locking mechanism is insufficient during the shearing process, the side clearance between the upper and lower shear blades will change, resulting in unqualified product quality.

[0003] In response, Chinese patent application number CN201921403794.0 discloses a shear blade locking device on a fixed-length shearing machine for wire rod production lines. The device includes a locking cylinder, a plunger, a piston rod, and a locking wedge. The locking cylinder is installed on the fixed-length shearing machine, and an oil inlet is provided on the upper part of its side wall. The plunger is installed in the locking cylinder, and a sealing ring is installed on the upper part of the plunger. A locking spring is installed on the plunger between the sealing ring and the cylinder head. The lower end of the plunger is fixedly connected to the upper end of the piston rod, and the lower end of the piston rod is fixedly connected to a cotter pin. The locking wedge is installed on the piston rod. This utility model uses a combination of a locking nut and a cotter pin for locking, making the locking device more secure after locking and less prone to nut loosening. This makes the operation of the upper shear blade locking device more convenient and faster, reducing the manpower required for operation and saving a significant amount of time, thus improving work efficiency.

[0004] The device uses a locking wedge to engage with the inclined surface of the upper shear blade assembly to lock the shear blade assembly in place. However, the upper shear blade assembly is installed facing upwards, and the locking wedge is in a movable state before engaging with the upper shear blade assembly. This means that the upper shear blade assembly is not limited before installation, has poor stability, and is prone to falling off, making the installation of the upper shear blade assembly quite inconvenient.

[0005] Therefore, in order to solve the above problems, a shear blade on a fixed-length shearing machine for wire rod production line is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide an upper shear blade for a fixed-length shearing machine in a wire rod production line, in order to solve the problem mentioned in the background art where the prior art device can lock the shear blade assembly by setting a locking wedge to fit against the inclined surface of the upper shear blade assembly. However, the upper shear blade assembly is installed upwards, and the locking wedge is in a movable state before fitting against the upper shear blade assembly. This means that the upper shear blade assembly has no limit before installation, has poor stability, and is prone to falling off, resulting in the inconvenience of installing the upper shear blade assembly.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an upper shear blade for a fixed-length shearing machine in a wire rod production line, comprising: a shear arm, a mounting groove being provided on the bottom surface of the shear arm, a mounting seat being installed on the inner side of the mounting groove, and an upper shear blade body being installed on the bottom surface of the mounting seat by screws; A movable groove is provided on the right side wall of the mounting groove, and a wedge-shaped block is integrally formed on the inner wall of the movable groove. The scissor arm is equipped with a fixed structure, which includes a movable block. The movable block is movably installed inside the movable slot. A wedge-shaped surface is provided on the left side wall of the movable block, and a fastening bolt is inserted into the bottom surface of the movable block.

[0008] Preferably, the left and right side walls of the mounting base are inclined surfaces, and the left side wall of the wedge block fits against the right side wall of the mounting base.

[0009] Preferably, the movable block and the wedge block are staggered.

[0010] Preferably, the wedge-shaped surface abuts against the right side wall of the mounting base.

[0011] Preferably, the fastening bolt passes through the movable block, and its upper end is threadedly connected to the inner wall of the movable groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by opening a movable groove inside the mounting groove and reserving a wedge block inside the movable groove, when the mounting seat is inserted into the mounting groove, the wedge block cooperates with the mounting groove to limit the upper end of the mounting seat, which can effectively solve the problem of poor installation stability of the upper shear blade body before fixing, save time and improve work efficiency.

[0013] This utility model features a fixed structure that bolts the upper shear blade body to the mounting base. The mounting base is positioned in front of the shear arm, aligning its upper end with the mounting groove. Moving the mounting base backward inserts it into the groove. The left end of the mounting base abuts against the left side wall of the groove, and the right end abuts against the left side wall of the wedge block. The mounting groove, in conjunction with the wedge block, limits the upper end of the mounting base, effectively preventing it from falling downward. The movable block is then inserted upward into the movable groove, and the upper end of the fastening bolt is inserted into the movable block. Rotating the fastening bolt allows it to penetrate the movable block, with its upper end threaded into the inner wall of the movable groove. Tightening the bolt causes the movable block to move upward within the groove. During this movement, the movable block abuts against the right side wall of the mounting base via its wedge-shaped surface, securing the mounting base stably. This design is convenient, saves time, and improves work efficiency. Attached Figure Description
