Description

Technical Field

[0001] This utility model relates to the field of double-sided shear accessories, and in particular to a rolling-cutting double-sided shear blade locking device. Background Technology

[0002] Roll-cutting double-sided shears are typically used on finishing lines of medium and heavy plate rolling mills to shear straightened and cooled steel plates longitudinally along both sides into finished specifications, achieving accurate control of plate width. The rolling-cutting double-sided shear blades use a rolling shearing method, resulting in minimal blade scratches and wear. The overlap between the upper and lower blades is consistent along the blade length, ensuring the straightness of the steel plate. Because the rolling-cutting double-sided shear operates continuously with high output, the blades wear quickly, requiring frequent blade replacement.

[0003] Traditional double-sided scissor blades are usually fixed to the blade holder and the blade post by a locking cylinder. The locking cylinder is a hydraulic locking structure, which requires oil circuits to be arranged on the blade post, which is relatively complicated. Moreover, the connection structure between the locking cylinder and the blade holder is also troublesome to connect, inconvenient to operate, and time-consuming. Therefore, this application proposes a rolling-cutting double-sided scissor blade locking device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rolling-cutting double-sided shear blade locking device, which solves the problems of inconvenient installation, troublesome and time-consuming blade replacement of traditional locking devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rolling-cutting double-sided shear blade locking device, comprising a blade holder, a blade base, and a shear blade body. The blade base is connected to both ends of the blade holder, and the shear blade body is fixed to the blade base by bolts. Locking device mounting slots are provided inside both ends of the blade holder, and locking devices are provided inside the locking device mounting slots. The blade base is fixed to the blade holder by locking devices.

[0006] The tool holder includes a tool holder body, which is configured as a concave plate with the opening facing downward, and the bottom front end is longer than the bottom rear end. Sliding grooves are provided on both top sides of the tool holder body, and a limiting slide rail that cooperates with the sliding groove is fixedly provided on the bottom front end of the tool holder.

[0007] The locking device includes a main housing, a pull rod, and a cover. The cover is fixed to one end of the main housing. The pull rod is disposed inside the main housing. The front end of the pull rod passes through the main housing and the tool holder and is fixedly connected to a locking block. The rear end of the pull rod passes through the cover. A limit plate is fixedly disposed on the body of the pull rod. A spring is disposed between the limit plate and the front end of the main housing. The locking device uses the force of the spring to drive the pull rod and the locking block to lock the rear side of the tool holder onto the tool holder.

[0008] With the above technical solution, the blade holder can be quickly aligned and installed on the blade holder through the cooperation of the limiting slide rail and the slide groove, and then locked and fixed by the locking device. The locking process of the locking device is very simple. By pushing the pull rod forward and then rotating it, the locking block can be flipped from facing down to facing up, so that the double-sided shear blade can be quickly fixed.

[0009] Furthermore, a V-shaped groove is provided on the main body of the tool holder corresponding to the position of the locking block, and the shape of the locking block is set to a triangle corresponding to the V-shaped groove;

[0010] With the above technical solution, during the process of installing the tool holder body into the tool post, the locking block can pass through the V-groove into the inner end of the tool holder body and lock the tool holder body after rotation.

[0011] Furthermore, two positioning holes are provided on the main body of the tool holder directly above the V-groove, and the locking block is provided with positioning rods corresponding to the two positioning holes;

[0012] Through the above technical solution, the cooperation between the positioning rod and the positioning hole enables the locking block to stably fasten the tool holder body and prevent it from falling off.

[0013] Furthermore, the cover is fixedly connected to the main housing by screws, and the cover is also fixed to the tool holder by bolts;

[0014] Furthermore, the cover is provided with a movable groove, and a limit rod is provided on the rod body of the pull rod, the limit rod moving inside the movable groove;

[0015] Furthermore, the opening path of the movable groove is set in a "U" shape, and one end penetrates through the top of the cover. When the limiting rod moves from one end of the movable groove to the other end, the pull rod rotates 180 degrees.

[0016] With the above technical solution, the pull rod can be rotated to a specified position during rotation, which can ensure that the tool holder is fixed in one go during installation.

[0017] Furthermore, a wheel is provided at the rear end of the pull rod, allowing manual control of the pull rod's rotation;

[0018] With the above technical solution, the locking device can be manually operated to control the locking and unlocking.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the tool holder can be fixed on the tool post by the locking device. After the tool holder is placed on the tool post, push the pull rod forward to drive the locking block into the tool holder. Then rotate the pull rod to make the locking block rotate 180 degrees. Then release the pull rod. Under the action of the spring, the pull rod moves backward, driving the locking block to move backward and locking the rear plate of the tool holder, thus locking the tool holder. It is very convenient and does not require the installation of oil circuits.

[0021] 2. In this utility model, the blade holder can be quickly aligned and installed on the blade holder through the cooperation of the limiting slide rail and the slide groove, making it more convenient and less labor-intensive to replace the shear blade. The rotation of the pull rod can be rotated to a fixed angle through the cooperation of the limiting rod and the movable groove, making the operation simple. Attached Figure Description
