Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel strip production technology, specifically a novel steel strip shearing device. Background Technology
[0002] Steel strip is a long, thin material made of steel, commonly used in various industrial and construction projects. Its main function is to strengthen, support, or enhance the strength of structures. Steel strip can be divided into several types, such as cold-rolled steel strip, hot-rolled steel strip, and galvanized steel strip, and is widely used in manufacturing, the automotive industry, and construction engineering. Cutting steel strip requires specialized tools to ensure accuracy and avoid damage to the material. As an important engineering material, steel strip has a wide range of applications. Choosing the right tools is crucial when cutting steel strip; different cutting tools can be selected based on specific needs and the thickness of the steel strip to ensure accuracy and efficiency.
[0003] When steel strips are coiled or used, they need to be cut at the ends. The conventional cutting method is to cut manually with scissors or a cutting saw. This can easily lead to uneven cutting, large errors in the cutting position, and reduced stability. Therefore, a new type of steel strip cutting device is designed to limit the position of the steel strip and maintain the flatness of the cut to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a novel steel strip shearing device that has the advantages of limiting the position of the steel strip and maintaining the flatness of the cut. It solves the problem that the conventional method of shearing steel strips is to manually cut it with scissors or a cutting saw, which can easily lead to uneven cutting, large errors in the cutting position, and reduced stability.
[0006] (II) Technical Solution
[0007] To achieve the aforementioned objectives of limiting the position of the steel strip and maintaining the flatness of the shearing, this utility model provides the following technical solution: A novel steel strip shearing device includes a base plate and support legs installed on the underside of the base plate. A placement plate is installed on the upper side of the base plate, and a limiting plate is installed inside the placement plate. A support frame is fixedly installed on the upper side of the placement plate, and the lower end of the support frame is located at both ends of the placement plate. A lower pressure plate is installed on the inner wall of the support frame, and an installation groove is installed on the lower side of the lower pressure plate. The two ends of the installation groove are slidably connected to the inner wall of the support frame. A buffer mechanism is provided inside the installation groove, and a steel blade is provided on the lower side of the buffer mechanism. The steel blade is located above the limiting plate. One end of the steel strip passes through the upper side of the placement plate and is positioned between two limiting plates. The distance between the limiting plates is adjusted according to the size of the steel strip to keep the steel strip stable as it passes through, preventing it from shifting during cutting. The lower pressure plate moves vertically, driving the mounting groove, its lower buffer mechanism, and the steel blade to move vertically to shear the steel strip. The buffer mechanism increases the contact force between the steel blade and the steel strip, keeping it stable before the actual cutting and improving the shearing accuracy.
[0008] Preferably, the placement plate has an elongated groove inside, and an electric slider is installed inside the groove. The limiting plate is fixedly installed on the upper side of the electric slider, and the lower side of the limiting plate is located at the upper end of the elongated groove. The electric slider is installed inside the elongated groove, and two electric sliders form a group, driving the same limiting plate to move. The limiting plate has an opening in the middle, which can fully accommodate the steel knife. The two limiting plates move towards each other to clamp the two sides of the steel strip.
[0009] Preferably, the inner wall of the elongated groove is provided with a limiting rod, and both ends of the limiting rod are fixedly connected to the inner wall of the elongated groove. The limiting rod passes through the interior of the electric slider, and the electric slider is slidably connected to the outer side of the limiting rod. The electric slider and the limiting rod are used in conjunction, and the limiting rod is used to restrict the position of the electric slider so that it can move stably and drive the limiting plate to move horizontally.
[0010] Preferably, a pneumatic cylinder is fixedly installed at the upper end of the support frame, and the output end of the pneumatic cylinder is located inside the support frame. The upper side of the mounting groove is fixedly connected to the output end of the pneumatic cylinder. The pneumatic cylinder is fixed inside the support frame, and its output end is located inside the support frame and fixedly connected to the upper side of the lower pressure plate. The pneumatic cylinder drives the lower pressure plate to move vertically on the inner wall of the support frame, indirectly causing the steel blade to cut the steel strip.
[0011] Preferably, the buffer mechanism includes a mounting groove and a sliding plate, with the sliding plate mounted on the inner wall of the mounting groove. Both ends of the sliding plate are slidably connected to the inner wall of the mounting groove, and a steel blade is fixedly mounted on the lower side of the sliding plate. The sliding plate moves vertically along the inner wall of the mounting groove, and the steel blade is positioned on the lower side of the sliding plate. The dimensions of the inner wall of the mounting groove correspond to the outer dimensions of the sliding plate, preventing it from deviating from its track.
[0012] Preferably, a buffer spring is installed inside the mounting groove, with its lower end fixedly connected to the upper side of the sliding plate and its upper end fixedly connected to the inner wall of the mounting groove. A mounting component is fixedly installed on the lower side of the sliding plate, and a steel blade is fixedly installed at the lower end of the mounting component. When the steel blade contacts the steel strip, the sliding plate pushes against the buffer spring and moves into the mounting groove. The elastic force generated by the buffer spring applies a preload to the steel blade, keeping the steel strip stable. The buffer spring also has a damper inside, which can protect the buffer spring. The steel blade is fixedly installed at the lower end of the mounting component by bolts. At least three mounting components are installed, and the steel blade can be easily removed from the bottom of the mounting component.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a novel steel strip shearing device with the following advantages: This novel steel strip shearing device passes one end of the steel strip through the upper side of the placement plate, which is set between two limiting plates. The distance between the limiting plates is adjusted according to the size of the steel strip to keep the steel strip stable when passing through, so that it will not deviate during cutting. Then, the vertical movement of the lower pressure plate drives the mounting groove and the buffer mechanism and steel blade below it to move vertically to shear the steel strip. The buffer mechanism increases the contact force between the steel blade and the steel strip, so that it can remain stable before the actual cutting, resulting in better shearing accuracy. This achieves the effect of limiting the position of the steel strip and maintaining the flatness of the shearing. Attached Figure Description

[0027] The electric slider 13 is used in conjunction with the limiting rod 14. The limiting rod 14 is used to limit the position of the electric slider 13 so that it can move stably and drive the limiting plate 9 to move horizontally.
