Description

Technical Field

[0001] This utility model relates to the field of shearing machines, specifically a cleaning structure for shearing machines. Background Technology

[0002] A cleaning structure for shearing machines is a device specifically designed for cleaning the blades of shearing machines. Its main function is to remove various impurities that adhere to the blade surface during the shearing process, such as metal shavings, lubricating oil residue, and dirt on the sheet metal surface. By cleaning the blades, the good performance of the blades can be maintained, the service life of the blades can be extended, and the accuracy and quality of the shearing operation of the shearing machine can be ensured.

[0003] The announcement number is CN220698332U, which specifically discloses a sheet metal shearing machine for mechanical processing. The shearing machine includes a shearing machine body, with a cleaning mechanism installed on the outer wall of the shearing machine body. A power plug is fixedly connected to the left side of the shearing machine body, and a control panel is fixedly connected to the right side of the shearing machine body. The cleaning mechanism includes a cleaning frame fixedly connected to the outer wall of the shearing machine body. In the cleaning structure design of the shearing machine, the choice to pull the blade out from the inside of the scraper for cleaning is based on considerations of operational convenience and safety. This method can, to some extent, avoid violent direct collisions between the blade and the scraper, while utilizing the edge of the scraper to remove impurities from the blade surface. However, due to limitations in manufacturing processes and actual installation, minute gaps inevitably exist between the blade and the scraper. From a manufacturing perspective, it's difficult to guarantee absolute dimensional accuracy for either the blade or the scraper during production. For example, the thickness of the blade and the internal dimensions of the scraper may deviate slightly due to factors such as the precision errors of the processing equipment and the thermal expansion and contraction of materials. Even if a suitable gap is reserved during the design phase, the gap may not perfectly match the ideal state after the actual parts are assembled. In terms of installation, the skill level of the installer and the installation environment also affect the gap. If the installation environment is not clean enough, and tiny impurities get between the blade and the scraper, the gap may become larger or irregular. Moreover, if the relative positions of the blade and the scraper are not precisely adjusted during installation, the gap may not meet requirements. These minute gaps can become a hidden danger of incomplete cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning structure for a shearing machine. Using this device solves the problem of insufficiently clean installation environments, where tiny impurities can get between the blade and scraper, potentially causing the gap to widen or become irregular. Furthermore, if the relative positions of the blade and scraper are not precisely adjusted during installation, the gap may not meet requirements, and these tiny gaps can become a hidden danger of incomplete cleaning.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5The present invention provides a technical solution: a cleaning structure for a shearing machine, comprising a base 1, a first support plate 2 fixedly connected above the base 1, a hydraulic cylinder 3 fixedly connected to the upper end of the first support plate 2, a hydraulic rod 4 fixedly connected to the output end of the hydraulic cylinder 3, a blade 5 fixedly connected to the lower end of the hydraulic rod 4, a vacuum cleaner 8 connected to the outside of the base 1, a pushing mechanism 6 provided on the outside of the hydraulic rod 4, and an elastic mechanism 7 provided inside the hydraulic rod 4;

[0022] The pushing mechanism 6 includes a first connecting rod 601 disposed outside the hydraulic rod 4. A second support plate 602 is fixedly connected to the lower end of one side of the first connecting rod 601. A cylinder 603 is fixedly connected to the upper side of one side of the first support plate 602. A pneumatic rod 604 is fixedly connected to the output end of the cylinder 603. A first hole 605 is provided inside the pneumatic rod 604. The inner side of the first hole 605 fits against the outer side of the second connecting rod 606. The second connecting rod 606 has a cuboid shape, so that the second connecting rod 606 will not shake or rotate when moving inside the first hole 605. A second connecting rod 606 is installed inside the first hole 605. A third support plate 607 is fixedly connected to the lower middle of the first connecting rod 601. A first guide groove 608 is provided on one side of the third support plate 607. Point a is provided on the outer side of the upper end of the first guide groove 608, point b is provided on the inner side of the upper end of the first guide groove 608, point c is provided on the outer side of the lower end of the first guide groove 608, and point d is provided on the inner side of the lower end of the first guide groove 608. A first guide rod 609 is provided on the inner side of the first guide groove 608. A scraper 6 is slidably connected to the end of the second connecting rod 606 near the hydraulic rod 4. 10. A second guide groove 611 is provided on the side of the third support plate 607 near the hydraulic rod 4. A second guide rod 612, which is fixedly connected to the scraper 610, is provided inside the second guide groove 611. Point a of the first guide groove 608 is closer to the hydraulic rod 4 than point b of the first guide groove 608, and point c of the first guide groove 608 is farther away from the hydraulic rod 4 than point d of the first guide groove 608. This allows the first guide rod 609 to move to the side of the first guide groove 608 near the hydraulic rod 4 when it moves downward to the position of point a of the first guide groove 608. When the guide rod 609 moves to point c of the first guide groove and moves upward, the first guide rod 609 can move to the side of the first guide groove 608 away from the hydraulic rod 4. The appearance structure of the second guide groove 611 is wavy, and the second guide groove 611 and the second guide rod 612 are fitted with a clearance fit, so that the second guide rod 612 will swing when it moves inside the second guide groove 611. The length of the second guide rod 612 is greater than the distance between the two inner sides of the first guide groove 608, so that the second guide rod 612 will not move out of the inner side of the first guide groove 608.

[0023] The elastic mechanism 7 includes a slider 701 fixedly connected to the end of the first connecting rod 601 near the central axis of the hydraulic rod 4. The hydraulic rod 4 has a groove 702 inside, and the slider 701 is nested inside the groove 702. A spring 703 is fixedly connected to the upper end of the slider 701. The upper end of the spring 703 is fixedly connected to the hydraulic rod 4. The width of the end of the slider 701 near the hydraulic rod 4 is greater than the width of the end of the slider 701 away from the hydraulic rod 4, and the central axis of the slider 701 is perpendicular to the upper surface of the first support plate 2, so that the slider 701 will not move out of the inner side of the groove 702 when it moves inside the groove 702.

[0024] When the shearing machine's blade 5 finishes cutting and needs cleaning, the cylinder 603 is activated, causing the air rod 604, the first hole 605, and the second connecting rod 606 to move downwards. This causes the first guide rod 609 to move downwards. Because point a of the first guide groove 608 is closer to the hydraulic rod 4 than point b, and point c of the first guide groove 608 is farther from the hydraulic rod 4 than point d, the first guide rod 609 moves downwards towards the hydraulic rod 4. This causes the second connecting rod 606 and the scraper 610 to move towards one side of the blade 5 and to clean the surface of the blade 5. At this time, the second guide rod 612 moves downwards. Because the second guide groove 611 has a wavy shape, the second guide rod 612 and the scraper 610 swing back and forth, increasing the cleaning area and improving the cleaning effect. At this time, the debris that falls from the vacuum cleaner 8 can be sucked away.

[0025] When the first guide rod 609 moves to position c, it moves upward to the side of the first guide groove 608 away from the hydraulic rod 4. The scraper 610 will leave the outside of the tool 5. At this time, the scraper 610 swings back and forth, causing the debris adhering to the outside of the scraper 610 to fall off under the action of inertia, so that the scraper 610 will have a better cleaning effect in the next cleaning.

[0026] When the blade 5 cuts the sheet metal, the second support plate 602 is blocked by the sheet metal. As the hydraulic rod 4 continues to move downwards, it exerts pressure on the spring 703, causing the second support plate 602 to elastically press against the sheet metal. During shearing operation, when the material being sheared has uneven thickness or hardness, a large impact force can easily be generated. For example, when shearing metal sheets with welds, the hardness of the weld area is usually higher than other parts of the sheet metal. Using elastic pressing, the elastic device can act as a buffer, absorbing these impact forces and preventing damage to the blade 5 and other components of the shearing machine from sudden, large impacts.
