Abstract
Description
Technical Field
[0001] This utility model relates to the field of strip steel processing technology, and in particular to a thin strip steel edge-cutting disc shear that facilitates the switching of cutting blades. Background Technology
[0002] The edge-trimming disc shear is used to shear the burrs and cracks on the sides of hot-rolled steel strip after it has been pressed and rolled. The sheared steel strip is then coiled to form a steel coil. The two blades of this shearing machine are made into discs for longitudinally shearing the edges of steel plates and strips or longitudinally shearing steel plates and strips into narrow strips.
[0003] In thin strip steel trimming disc shears, a modular cutter design offers several advantages: The modular design allows for independent design, manufacture, and replacement of each part of the cutter. This modular design makes maintenance or upgrades easier, requiring only the replacement or repair of damaged parts without replacing the entire cutter system. The modular design also allows for greater flexibility in cutter adjustments.
[0004] Traditional thin strip steel cutting disc shears with a split-type blade design have shortcomings in use. Their split blades cannot be quickly disassembled and switched according to the material and specifications of the thin strip steel to be cut, thus limiting their use. Therefore, their structure needs to be optimized and improved. Summary of the Invention
[0005] The purpose of this invention is to overcome the aforementioned problems in traditional technology and provide a thin strip steel edge-cutting disc shear that facilitates blade switching.
[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A thin strip steel trimming disc shear for easy blade switching includes an upper cutting blade assembly and a lower cutting blade assembly. The upper cutting blade assembly includes an upper support base, which movably supports an upper combined cutting blade via an upper blade shaft. The lower cutting blade assembly includes a lower support base, which movably supports a lower combined cutting blade via a lower blade shaft. The upper and lower combined cutting blades have identical structures. The upper combined cutting blade includes a mounting plate, an axial positioning post, a convex box, a turntable, a radial locking plate, a drive motor, a drive gear, and a split-type blade block. The split-type blade block consists of a fan-shaped annular blade section and an arc-shaped plate located at its inner end. The component comprises a fan-shaped annular blade with an axial positioning hole and an arc-shaped plate with a radial locking groove. Multiple sets of axial positioning pins that mate with the axial positioning holes are circumferentially mounted on the outer side of the mounting plate near its periphery. A convex box and a drive motor are mounted at the center of the outer side of the mounting plate. A turntable is internally restricted within the convex box. A drive gear for rotating the turntable is mounted at the output end of the drive motor. Multiple oblique push grooves are circumferentially provided on the turntable. Multiple radial sliding grooves are circumferentially provided on the outer side plate of the convex box. A radial locking plate is jointly restricted in the oblique push grooves and the corresponding radial sliding grooves.
[0007] Furthermore, in the aforementioned thin strip steel edge-cutting disc shear that facilitates blade switching, the fan-shaped annular blade sections of each of the separate blade blocks can be spliced together to form a ring-cutting blade, and the arc-shaped plate sections of each of the separate blade blocks can be spliced together to form a tube section.
[0008] Furthermore, in the aforementioned thin strip steel edge-cutting disc shear that facilitates blade switching, the radial locking groove is an open groove or a closed groove.
[0009] Furthermore, in the aforementioned thin strip steel edge-cutting disc shear that facilitates blade switching, the inside of the turntable is provided with a circular hole, and the inner edge of the circular hole is provided with an incomplete tooth groove that engages with the drive gear.
[0010] Furthermore, in the aforementioned thin strip steel edge-cutting disc shear that facilitates blade switching, the number of each of the oblique push groove and radial slide groove is equal to the number of the split blade blocks.
[0011] Furthermore, in the aforementioned thin strip steel edge-cutting disc shear that facilitates blade switching, the radial locking plate is composed of a mounting block, an anti-detachment head, and a locking plate portion. The mounting block is slidably restricted in a corresponding radial groove, and an anti-detachment head that is slidably restricted in an inclined push groove is installed on the inner side of the mounting block. The mounting block extends radially along the mounting plate to form a locking plate portion that can be engaged in the corresponding radial locking groove.
[0012] The beneficial effects of this utility model are: The thin strip steel trimming disc shear provided by this utility model has two combined cutting blade structures, specifically including a mounting plate, axial positioning column, convex box, turntable, radial locking plate, drive motor, drive gear, and split-type blade blocks. When it is necessary to switch the split-type blade blocks according to the material and specifications of the thin strip steel to be trimmed, simply use the drive motor to drive the drive gear to rotate, the drive gear will then drive the turntable to rotate, and the turntable will then drive the radial locking plate to move radially, releasing the lock on the split-type blade blocks. At this time, the switching operation can be performed. After the switching is completed, the drive motor will drive the drive gear to rotate in the opposite direction, so that the radial locking plate can lock the split-type blade blocks again. The overall switching operation is quite convenient.
[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

The turntable 34, the radial locking plate 35, the drive motor 36, and the drive gear 37 together constitute a locking mechanism for locking the split-type cutter block 38.
[0019] The split-type cutter block 38 consists of a fan-shaped annular cutter portion 381 and an arc-shaped plate portion 382 located at its inner end. The fan-shaped annular cutter portion 381 has an axial positioning hole 383, and the arc-shaped plate portion 382 has a radial locking groove 384. Multiple sets of axial positioning pins 32 that mate with the axial positioning holes 383 are circumferentially mounted on the outer side of the mounting plate 31 near its periphery. A convex box 33 and a drive motor 36 are mounted at the center of the outer side of the mounting plate 31. The convex box 33 internally restricts the movement of a turntable 34. A drive gear 37 for driving the turntable 34 to rotate is mounted on the output end of the drive motor 36. The turntable 34 has multiple oblique push grooves 341 circumferentially, and the outer plate of the convex box 33 has multiple radial sliding grooves 331 circumferentially.
