Description

Technical Field

[0001] This utility model relates to the field of strip steel processing technology, specifically a rolling shear for strip steel processing. Background Technology

[0002] As a core shearing tool in the strip steel processing field, the technical performance of shearing tools directly affects the quality and production efficiency of steel products. These tools mainly consist of one or more pairs of rotating disc blades, which dynamically cut (slitting or trimming) continuously moving strip steel through their meshing motion. The core technology lies in using precisely controlled gaps and overlaps to generate shearing force. Compared to traditional stamping or guillotine shearing, the rolling shear process offers advantages such as continuous processing, high efficiency, and zero waste generation, making it particularly suitable for the continuous production line requirements of modern steel industry.

[0003] When fixing the blade on the cutter shaft, the blade is fitted onto the cutter shaft and then wrapped by a locking sleeve and tightened by a locking nut. The locking sleeve itself is fixed in the screw hole of the cutter shaft by screws. During installation, it is necessary to remove or install the screws one by one, which increases the cumbersomeness of fixing the blade. To address this, we designed a hobbing shear for strip processing, which enables the blade to be installed quickly. Utility Model Content

[0004] The purpose of this invention is to provide a rolling shear for strip processing to solve the problems mentioned in the background art.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Preferably, the spring telescopic rod includes a base column, a movable groove is provided in the base column, a strong spring is fixedly connected to the bottom wall of the movable groove, a disc is fixedly connected to the top of the strong spring, a movable rod is fixedly connected to the disc, and a circular hole is provided on the base column that moves perpendicularly to the movable rod. By setting the spring telescopic rod, it is easy to support the movable plate and retract when compressed, thereby driving the movable plate to move vertically.

[0008] Preferably, the bottom column is fixedly connected to the bottom wall of the first convex groove inside the cutter shaft, and the top end of the movable rod is fixedly connected to the lower surface of the movable plate. By setting the bottom column and the movable rod, it is convenient to make the bottom end of the movable rod rise and fall vertically on the bottom column.

[0009] Preferably, the inner circumference of the blade is provided with three grooves that are adapted to the clamping plate at equal intervals, and multiple blades are sleeved on the cutter shaft. By setting the clamping plate, the cutter shaft can drive the blade to rotate stably through the clamping plate, and the blade can cut the strip steel.

[0010] Preferably, ten spring telescopic rods are provided under the movable plate, with five spring telescopic rods forming a group. The two groups of spring telescopic rods are equally spaced on both sides of the lower surface of the movable plate. By evenly distributing the spring telescopic rods at the bottom of the movable plate, it is easier to increase the smoothness of the bottom of the movable plate when it is raised and lowered.

[0011] Preferably, the bottom end of the locking rod passes through the movable plate and extends between the two spring telescopic rods, and the top end of the locking rod passes through the first protrusion of the cutter shaft and extends to the surface of the cutter shaft. Several second protrusions are longitudinally provided on the movable plate. By setting the locking rod, it is easy to make the locking rod descend under force and rise under no force to lock the blade and limit the two sides of the blade.

[0012] Preferably, the positioning ring and the return spring are both located in the second protrusion inside the movable plate, and the bottom end of the return spring is fixedly connected to the inner bottom wall of the second protrusion. By setting the positioning ring and the return spring inside the movable plate, it is convenient to limit the lifting height of the lever.

[0013] Preferably, the movable plate is provided with control rods on both the front and back sides. The end of the control rod passes through the first protrusion of the cutter shaft and extends to the outside of the cutter shaft. The front and back sides of the cutter shaft are provided with limiting grooves to facilitate the vertical movement of the control rods. By providing control rods, it is convenient to control the lifting and lowering of the movable plate. When the force is pressed down, it is convenient for the blade to separate from the cutter shaft. When the force is released, the movable plate drives the locking rod to rise, so that the locking rod locks the blade on the cutter shaft.

[0014] Beneficial effects Compared with the prior art, the technical solution of this application has the following beneficial technical effects: This invention utilizes a retaining plate to limit the movement of the blade on the cutter shaft. A first groove inside the cutter shaft allows for the use of a spring-loaded telescopic rod to support the movable plate. Furthermore, a vertically movable retaining rod on the movable plate facilitates the positioning of the blade on the cutter shaft, reducing the cumbersome process of fixing the blade with bolts and other fasteners. This allows the hobbing shear for strip processing to quickly install and secure the blade. Attached Figure Description
