Description
Technical Field
[0001] This utility model relates to the field of steel strip processing equipment, and in particular to a steel strip cutting device. Background Technology
[0002] Currently, most steel strip cutting devices consist of a frame, a lower cutter, an upper cutter, and a lifting drive mechanism. The lower cutter and the lifting drive mechanism are fixedly mounted on the frame. The upper cutter is mounted on the lifting drive end of the lifting drive mechanism, which drives the upper cutter to reciprocate towards and away from the lower cutter. When the upper cutter approaches the lower cutter, it cuts the steel strip. During the cutting process, the upper cutter inserts into the cut end of the steel strip, and the two cut ends scrape against the two sidewalls of the upper cutter. Because the cut ends are often very sharp, this not only easily causes significant scratches and wear on the sidewalls of the upper cutter but also generates sharp noise, resulting in a short service life for the upper cutter and a noisy working environment for the cutting workers. This leads to increased operating costs and worker fatigue and irritability, significantly impacting the workers' physical and mental health. Therefore, it is essential to design a steel strip cutting device to solve the aforementioned technical problems. Utility Model Content
[0003] The purpose of this utility model is to solve the above-mentioned problems and shortcomings and provide a steel strip cutting device. This steel strip cutting device can effectively prevent the cut steel strip from scraping the side wall of the upper cutter. This not only greatly reduces the probability of large scratches and wear on the side wall of the upper cutter, but also effectively reduces the generation of sharp noise, thereby extending the service life of the upper cutter and effectively reducing the noise of the cutting operation environment. This reduces the cost of use and the probability of fatigue and irritability among cutting workers, thus ensuring the physical and mental health of workers.
[0004] The technical solution of this utility model is implemented as follows:
[0005] A steel strip cutting device is characterized by including a lifting drive mechanism, an upper cutter, and two elastic push arms. The upper cutter is mounted on the lifting end of the lifting drive mechanism, and the two elastic push arms are arranged in a V-shape, with the upper ends of the two elastic push arms connected to the lifting end of the lifting drive mechanism. The two elastic push arms are also arranged symmetrically about the blade of the upper cutter, and the bottom surface of the lower end of the elastic push arms is lower than the bottom surface of the upper cutter.
[0006] Preferably, a soft friction pad is provided on the bottom surface of the lower end of the elastic pusher arm.
[0007] Preferably, the lower end of the elastic pusher arm is an arc-shaped piece with a downward arc-shaped depression in the middle, and the soft friction piece is attached to the bottom surface of the arc-shaped piece.
[0008] Preferably, the two ends of the soft friction pad that curve upwards along with the arc-shaped plate are respectively locked to the arc-shaped plate by the first screw.
[0009] Preferably, the elastic pusher arm further includes a vertical plate and an inclined plate, the lower end of the vertical plate is connected to the upper end of the inclined plate, one side of the arc-shaped plate is connected to the lower end of the inclined plate, and the vertical plate is connected to the lifting end of the lifting drive mechanism.
[0010] Preferably, the arc-shaped piece, the inclined piece, and the vertical piece are an integral elastic steel sheet structure, with an arc-shaped transition connection between the arc-shaped piece and the inclined piece, and a circular arc transition connection between the inclined piece and the vertical piece.
[0011] Preferably, the lifting drive mechanism includes a positioning frame, a drive cylinder, and a positioning block. The drive cylinder is vertically mounted on the positioning frame with its extension end facing downwards. The positioning block is mounted on the extension end of the drive cylinder. The upper cutter is embedded in the bottom surface of the positioning block. The vertical piece is attached to the side wall of the positioning block and is fixed to the side wall of the positioning block by at least one second screw.
[0012] Preferably, the soft friction pad is a soft rubber sheet.
[0013] Preferably, the steel strip cutting device further includes a support base, the top surface of which is a horizontal support surface, a relief groove is formed in the middle of the horizontal support surface, a positioning groove is formed on the edge of the relief groove, a lower cutter is embedded in the positioning groove, the upper cutter is located directly above the relief groove, and two elastic push arms are respectively located directly above the horizontal support surface on both sides of the relief groove opening.
[0014] The beneficial effects of this invention are as follows: The steel strip cutting device has two elastic push arms, positioned in a V-shape on the lifting end of the lifting drive mechanism. The bottom surface of each elastic push arm is lower than the bottom surface of the upper cutter. During the cutting process, the two elastic push arms first press against the steel strip and then exert a force that pulls the two sections of steel strip away from each other. This ensures that the cut sections move away from the upper cutter, preventing the ends of the cut sections from scraping against the sides of the cutter. Therefore, this steel strip cutting device effectively prevents the cut steel strip from scraping against the sidewalls of the upper cutter. This significantly reduces the likelihood of large scratches and wear on the sidewalls of the upper cutter, effectively reduces sharp noise, extends the service life of the upper cutter, and reduces the noise of the cutting environment, thereby lowering operating costs and reducing worker fatigue and irritability, thus ensuring the physical and mental health of the workers. The two elastic pusher arms are symmetrically arranged about the blade of the upper cutter, which ensures that the cut point on the steel strip is accurately acted upon by the upper cutter, thus guaranteeing a very high cutting quality for the steel strip.

[0019] like Figure 1 As shown, the steel strip cutting device of this utility model includes a lifting drive mechanism 1, an upper cutter 2, and two elastic pusher arms 3. The upper cutter 2 is disposed on the lifting end of the lifting drive mechanism 1. The two elastic pusher arms 3 are arranged in a V-shape, with the upper ends of the two elastic pusher arms 3 connected to the lifting end of the lifting drive mechanism 1. The two elastic pusher arms 3 are symmetrically arranged about the blade 21 of the upper cutter 2, and the bottom surface of the lower end of the elastic pusher arms 3 is lower than the bottom surface of the upper cutter 2.
[0020] The steel strip cutting device has two elastic push arms 3, which are positioned in a V-shape on the lifting end of the lifting drive mechanism 1. The bottom surface of each elastic push arm 3 is lower than the bottom surface of the upper cutter 2. During the cutting process, the two elastic push arms 3 first press against the steel strip and then exert a force that pulls the two sections of steel strip away from each other. This prevents the ends of the cut sections from scraping against the sides of the upper cutter 2. Therefore, this steel strip cutting device effectively prevents the cut steel strip from scraping against the sidewalls of the upper cutter. This significantly reduces the likelihood of large scratches and wear on the sidewalls of the upper cutter, and also effectively reduces the generation of sharp noise, thus extending the service life of the upper cutter. It also effectively reduces the noise of the cutting environment, thereby lowering operating costs and reducing worker fatigue and irritability, ultimately ensuring the physical and mental health of the workers.
[0021] The two elastic pusher arms 3 are arranged symmetrically about the blade 21 of the upper cutter 2, which allows the upper cutter 2 to accurately act on the part of the steel strip to be cut, thus ensuring that the cutting quality of the steel strip is very high.
[0022] like Figure 1 and Figure 2 As shown, a soft friction plate 4 is provided on the bottom surface of the lower end of the elastic pusher arm 3. This enables the elastic pusher arm 3 to effectively and stably push the steel strip, thereby helping to further improve the reliability and applicability of the steel strip cutting device.
[0023] like Figure 2 As shown, the lower end of the elastic pusher arm 3 is an arc-shaped piece 31 with a downward-curving central section, and the soft friction plate 4 is attached to the bottom surface of the arc-shaped piece 31. The arc-shaped piece 31 not only facilitates the placement of the soft friction plate 4, but also makes the pushing and pressing of the soft friction plate 4 onto the steel strip more accurate and stable, thereby helping to further improve the reliability and applicability of the steel strip cutting device.
[0024] like Figure 2 As shown, the two ends of the flexible friction plate 4 that curve upwards along with the arc-shaped plate 31 are respectively locked to the arc-shaped plate 31 by the first screw 10. This stably confines the flexible friction plate 4 to the bottom surface of the arc-shaped plate 31, preventing the flexible friction plate 4 from detaching from the arc-shaped plate 31 when pushing the steel strip. This also meets the need for replacing the flexible friction plate 4, thereby helping to further improve the reliability and applicability of the steel strip cutting device.
[0025] The soft friction pad 4 can be locked by the first screw 10 and can also be glued to the arc-shaped piece 31, which can further improve the stability and reliability of the installation and positioning of the arc-shaped piece 31.
[0026] like Figure 1 and Figure 2 As shown, the elastic pusher arm 3 also includes a vertical plate 32 and an inclined plate 33. The lower end of the vertical plate 32 is connected to the upper end of the inclined plate 33, and one side of the arc-shaped plate 31 is connected to the lower end of the inclined plate 33. The vertical plate 32 is connected to the lifting end of the lifting drive mechanism 1. This elastic pusher arm 3 is very simple and reliable, which not only facilitates manufacturing and installation but also enables the elastic pusher arm 3 to exert a good elastic pushing effect, thereby helping to further improve the applicability of the steel strip cutting device.
[0027] like Figure 2 As shown, the arc-shaped plate 31, the inclined plate 33, and the vertical plate 32 are integrally formed as an elastic steel sheet structure. The arc-shaped plate 31 and the inclined plate 33 are connected by an arc-shaped transition, and the inclined plate 33 and the vertical plate 32 are connected by a circular arc transition. This not only further improves the ease of manufacturing the elastic pusher arm 3, but also gives the elastic pusher arm 3 a more stable and reliable structure, thereby helping to further improve the reliability and applicability of the steel strip cutting device.
[0028] like Figure 1 As shown, the lifting drive mechanism 1 includes a positioning frame 11, a drive cylinder 12, and a positioning block 13. The drive cylinder 12 is vertically mounted on the positioning frame 11 with its extension end facing downwards. The positioning block 13 is mounted on the extension end of the drive cylinder 12. The upper cutter 2 is embedded in the bottom surface of the positioning block 13. The vertical piece 32 abuts against the side wall of the positioning block 13 and is fixed to the side wall of the positioning block 13 by at least one second screw 20. This lifting drive mechanism 1 is very simple and reliable, which not only facilitates manufacturing but also achieves a very stable and reliable lifting drive function. Fixing the vertical piece 32 to the positioning block 13 with the second screw 20 facilitates and stably fixes the vertical piece 32 to the positioning block 13, which not only helps to improve the convenience of installing and positioning the elastic pusher arm 3 but also facilitates the replacement and maintenance of the elastic pusher arm 3.
[0029] The soft friction plate 4 is a soft rubber sheet. This not only gives the soft friction plate 4 a good friction effect, but also gives it high wear resistance and strength, which improves performance, extends service life, and reduces maintenance costs, thereby helping to further improve the applicability of the steel strip cutting device.
[0030] like Figure 1As shown, the steel strip cutting device also includes a support base 5, the top surface of which is a horizontal support surface 51. A relief groove 52 is provided in the middle of the horizontal support surface 51, and a positioning groove 53 is provided on the edge of the groove opening of the relief groove 52. A lower cutter 6 is embedded in the positioning groove 53, and an upper cutter 2 is located directly above the relief groove 52. Two elastic pusher arms 3 are located directly above the horizontal support surface 51 on both sides of the groove opening of the relief groove 52. The horizontal support surface 51 can horizontally support the steel strip to be cut, which can ensure the stability of the steel strip placement; the clearance groove 52 can provide clearance space for the upper cutter 2 to cut the steel strip, so as to avoid the upper cutter 2 directly interacting with the support seat 5; the upper cutter 2 can work together with the lower cutter 6 to cut the steel strip under the drive of the lifting drive mechanism 1; the two elastic pusher arms 3 can effectively push the steel strip on the horizontal support surface 51, which can help achieve a stable and reliable cutting effect, and further improve the reliability and applicability of the steel strip cutting device.
[0031] like Figure 3 and Figure 4 As shown, in actual use, the steel strip 100 is first placed on the horizontal support surface 51; then, the lifting drive mechanism 1 drives the two elastic pusher arms 3 and the upper cutter 2 to move downwards. The soft friction plates 4 on the two elastic pusher arms 3 will first press against the two sections of the steel strip 100 to be cut, and give the two sections of the steel strip to be cut a force that moves them away from each other. The two elastic pusher arms 3 can also play a certain role in restricting and pressing the steel strip. Then, the lifting drive mechanism 1 is used to make the upper cutter 2 quickly descend and contact the steel strip 100, which allows the upper cutter to be cut to be cut. The cutter 2 and the lower cutter 6 work together to cut the steel strip 100; and the two cut sections of steel strip can move to both sides of the cut, which can effectively prevent the cut steel strip from scraping the side wall of the upper cutter. This not only greatly reduces the chance of large scratches and wear on the side wall of the upper cutter, but also effectively reduces the generation of sharp noise, thereby extending the service life of the upper cutter and effectively reducing the noise of the cutting operation environment. This can reduce the cost of use and reduce the chance of fatigue and irritability of the cutting workers, which can better ensure the physical and mental health of the workers.
