Abstract
Description
Technical Field
[0001] This application relates to the field of steel cutting tools, specifically to a high-strength steel longitudinal shear serrated edge control device. Background Technology
[0002] Slitting of steel coils is a common slitting process in factories. The most common method for slitting steel coils is to place the steel coil on one side of the cutter, so that one end of the steel coil passes through the horizontally placed cutter and is wound onto a horizontally placed drum on the other side. During slitting, the steel coil, drum and cutter are controlled to move synchronously, so as to continuously cut and collect the steel coil.
[0003] When slitting steel coils, the shearing and tearing forces generated between the upper and lower blades are mainly used to achieve the slitting process. Since metal materials have a certain degree of plasticity and ductility, if there is an unsuitable axial angle between the equipment for recycling and winding the slitting waste edges and the steel coil to be sheared, serrated edges are easily generated at the slitting cut of the steel coil during the shearing process, which will have an adverse effect on product quality. Summary of the Invention
[0004] This application provides a high-strength steel slitting sawtooth edge control device, which solves the current problems of steel coil slitting waste recycling occupying a lot of layout space and the sawtooth edge phenomenon during slitting seriously affecting product quality. It realizes the technical effect of effectively recycling slitting waste in a small space, while effectively mitigating or even controlling the generation of slitting sawtooth edges.
[0005] According to one aspect of the embodiments of this application, a high-strength steel longitudinal shearing sawtooth edge control device is provided, comprising:
[0006] A lower cutter shaft and an upper cutter shaft are arranged parallel to each other. Each end of the upper cutter shaft is fitted with an annular upper cutter, and each end of the lower cutter shaft is fitted with an annular lower cutter. The lower cutter is located outside the upper cutter on the same side. The outer diameter of the upper cutter is larger than the diameter of the upper cutter shaft, and the outer diameter of the lower cutter is larger than the diameter of the lower cutter shaft.
[0007] Spacers, two spacers are respectively fitted on both ends of the upper cutter shaft and are both located on the outside of the upper cutter on the same side. The outer diameter of the spacers is smaller than the outer diameter of the upper cutter and larger than the diameter of the upper cutter shaft.
[0008] Waste edge roll is disposed around the upper cutter shaft and perpendicular to the upper cutter shaft.
[0009] In one possible implementation,
[0010] The outer edge of the upper blade has a shortest straight-line distance with the outer edge of the spacer on the same side, and the angle between the direction vector of the shortest straight-line distance and the length direction of the upper blade axis is not greater than 15°.
[0011] In one possible implementation,
[0012] The lower cutting axis is located above the upper cutting axis.
[0013] In one possible implementation,
[0014] The waste edge roll is disposed around the outside of the spacer and close to the spacer.
[0015] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0016] The high-strength steel slitting sawtooth edge control device provided in this application uses a waste edge roll drum perpendicular to the lower and upper cutter shafts to collect the waste edges generated during the slitting process of the steel coil. This fully utilizes vertical space in actual production, saving considerable floor space while ensuring effective collection of slitting waste edges. Because the angle between the axial direction of the waste edge roll drum and the axial directions of the lower and upper cutter shafts is unsuitable, when waste edges that have not yet separated from the steel coil are collected by the waste edge roll drum during slitting, sawtooth edges will be generated at the slitting cut edge of the steel coil. Therefore, this embodiment further provides spacers on the outer sides of both upper cutters. The diameter of these spacers is slightly smaller than that of the upper cutter, so as not to affect the normal shearing of the lower cutter. When waste edges are generated during slitting and are rolled by the waste edge roll drum, the spacers can reduce the slope of the angle between the waste edges and the remaining steel coil after slitting, thereby effectively controlling the generation of sawtooth edges and improving product quality.

[0022] This embodiment discloses a high-strength steel longitudinal shearing sawtooth edge control device, which includes:
[0023] The upper and lower cutting shafts 1 and 2 are arranged parallel to each other. At least one annular upper cutting blade 101 is fitted at each end of the upper cutting shaft 1, and at least one annular lower cutting blade 201 is fitted at each end of the lower cutting shaft 2. The lower cutting blade 201 is located outside the upper cutting blade 101 on the same side. The outer diameter of the upper cutting blade 101 is larger than the diameter of the upper cutting shaft 1, and the outer diameter of the lower cutting blade 201 is larger than the diameter of the lower cutting shaft 2. By setting multiple upper and lower cutting blades, multiple steel strips can be cut simultaneously.
[0024] Spacer 102, two spacer 102 are respectively sleeved on both ends of the upper cutter shaft 1 and are both located on the outside of the upper cutter 101 on the same side. The outer diameter of the spacer 102 is smaller than the outer diameter of the upper cutter 101 and larger than the diameter of the upper cutter shaft 1.
[0025] Waste edge roll 3 is disposed around the upper cutter shaft 1 and perpendicular to the upper cutter shaft 1.
[0026] Specifically, such as Figure 1As shown, the high-strength steel slitting sawtooth edge control device provided in this embodiment uses a waste edge drum 3 perpendicular to the lower cutter shaft 2 and the upper cutter shaft 1 to wind and collect the waste edge 401 generated during the slitting process of the steel coil 4. In actual production, this device makes full use of vertical space, effectively collecting the waste edge 401 generated during slitting while saving considerable floor space. However, due to the unsuitable angle between the axial direction of the waste edge drum 3 and the axial directions of the lower cutter shaft 2 and the upper cutter shaft 1, the waste edge is not yet separated from the steel coil 4 during the slitting process. When the waste edge 401 is wound and collected by the waste edge roll 3, it will cause a serrated edge at the slitting cut of the steel coil 4. Therefore, in this embodiment, a spacer 102 is further provided on the outer side of the upper blade 101 on both sides. The diameter of the spacer 102 is slightly smaller than the diameter of the upper blade 101, so it will not affect the normal cutting of the lower blade 201. When the waste edge 401 is generated during slitting and is wound by the waste edge roll 3, the spacer 102 can reduce the slope of the angle between the waste edge 401 and the remaining steel coil 4 after slitting, thereby effectively controlling the generation of serrated edges and improving product quality.
[0027] In a preferred embodiment,
[0028] The outer edge of the upper blade 101 has a shortest straight-line distance with the outer edge of the spacer 102 on the same side, and the angle between the direction vector of the shortest straight-line distance and the length direction of the upper blade shaft 1 is not greater than 15°.
[0029] In a preferred embodiment,
[0030] The lower cutting shaft 2 is located above the upper cutting shaft 1.
[0031] In a preferred embodiment,
[0032] The waste edge roll 3 is disposed around the outside of the spacer 102 and close to the spacer 102.
[0033] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, please refer to each other. Each embodiment focuses on describing the differences from other embodiments.
