Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of guardrail production apparatus technology, and more specifically, to a shearing machine for guardrail processing. Background Technology
[0002] Shearing machines are a type of forging and pressing machinery, primarily used in the metal processing industry. Their products are widely applicable to industries such as aviation, light industry, metallurgy, chemical engineering, construction, shipbuilding, automotive, power, electrical appliances, and decoration, providing specialized machinery and complete sets of equipment.
[0003] Currently, operators frequently use shearing machines when processing guardrail panels. While existing shearing machines can perform basic shearing operations on guardrail panels, they often warp during the shearing process because the top right side of the guardrail panel is not subjected to downward pressure. This results in uneven cuts, affecting subsequent processing and yield. Therefore, improvements are needed. Utility Model Content

[0009] As a preferred embodiment of this utility model, a long rod is fixedly sleeved at the bottom end of the outer surface of the rotating shaft, and movable rods are hinged at both ends of the long rod.
[0010] As a preferred embodiment of this utility model, the other end of the movable rod is hinged to a movable block located inside the connecting plate, and the outer surface of the movable block is movably connected to the interior of the connecting plate.
[0011] As a preferred embodiment of this utility model, a guide plate is fixedly connected to the bottom end of the movable block, and the bottom and top ends of the guide plate are movably connected to the top end of the workbench and the bottom end of the connecting plate, respectively.
[0012] As a preferred technical solution of this utility model, a moving block is movably connected to the left side of the top of the workbench, and a second pneumatic cylinder is fixedly installed on the top of the moving block. The bottom end of the second pneumatic cylinder passes through the moving block and extends to the outside of the top of the inner surface of the moving block and is fixedly connected to a long plate. The left side of the long plate is movably connected to the inner surface of the moving block.
[0013] As a preferred technical solution of this utility model, a third motor is fixedly installed at the top left side of the workbench, and a lead screw is fixedly sleeved at the other end of the output shaft of the third motor. The right end of the lead screw passes through the workbench and extends into the interior of the workbench and is movably connected to the interior of the workbench.
[0014] As a preferred technical solution of this utility model, a slider is threadedly sleeved on the left side of the outer surface of the lead screw, the outer surface of the slider is movably connected to the interior of the worktable, the top end of the slider is fixedly connected to the bottom end of the moving block, and the top right end of the slider is fixedly connected to a pad located inside the worktable, and its outer surface is movably connected to the interior of the worktable.
[0015] The beneficial effects of the embodiments disclosed herein are as follows:
[0016] 1. In this disclosure, by setting up a first motor, a rotating shaft, a rotating block, a short shaft, and a pressure plate, the operator starts the first motor, which causes the rotating shaft and the rotating block to rotate. This causes the outer surface of the rotating block to squeeze and push the outer surface of the short shaft, which in turn causes the short shaft to drive the pressure plate to move downward. Ultimately, the bottom end of the pressure plate can exert downward pressure on the right side of the top of the guardrail, preventing the guardrail from warping during the shearing process and thus improving the yield of the guardrail.
[0017] 2. In this disclosure, by setting up a second motor, a rotating shaft, a long rod, a movable rod, and guide plates, the operator starts the second motor, which causes the rotating shaft and the long rod to rotate. This causes the long rod to drive the two movable blocks to move the two guide plates in opposite directions through the two movable rods. This reduces the distance between the two guide plates, thereby enabling the guiding operation of guardrail panels of different specifications. This avoids the guardrail panels from shifting during subsequent shearing operations, which would render the guardrail panels unusable. Attached Figure Description

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0028] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0029] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.
[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0032] like Figures 1-6As shown, a shearing machine for processing guardrail panels according to an embodiment of the present disclosure is illustrated, including a workbench 1. A connecting frame 2 is fixedly connected to the right side of the top of the workbench 1. A rectangular plate 3 is fixedly installed at the top right side of the connecting frame 2. A first motor 4 is fixedly installed on the right side of the rectangular plate 3. A rotating shaft 5 is fixedly sleeved at the other end of the output shaft of the first motor 4. A rotating block 6 is fixedly sleeved on the outer surface of the rotating shaft 5. A short shaft 7 is movably connected inside the rotating block 6. A pressure plate 8 is fixedly connected to the left side of the short shaft 7. The bottom end of the pressure plate 8 passes through the rectangular plate 3 and extends to the outside of the bottom end of the rectangular plate 3, and its outer surface is movably connected to the inside of the rectangular plate 3.
[0033] Because the pressure plate 8 is located inside the rectangular plate 3, it is more stable when it moves downward. The design of the pressure plate 8 also prevents the guardrail from warping and causing uneven cuts during subsequent shearing operations.
[0034] In some examples, a first pneumatic cylinder 9 is fixedly connected to the top of the connecting frame 2. The bottom end of the first pneumatic cylinder 9 passes through the connecting frame 2 and extends to the outside of the top of the inner surface of the connecting frame 2, and is fixedly connected to a shearing blade 10. Both the front and rear ends of the shearing blade 10 are movably connected to the inner surface of the connecting frame 2.
[0035] Since the outer surface of the No. 1 pneumatic cylinder 9 and the interior of the top of the connecting frame 2 are both smooth, the friction between the outer surface of the No. 1 pneumatic cylinder 9 and the interior of the connecting frame 2 can be reduced, thereby improving the service life of the No. 1 pneumatic cylinder 9.
[0036] In some examples, the front and rear ends of the shearing blade 10 are fixedly connected to limiting blocks 11 located inside the front, rear and rear of the connecting frame 2, and the outer surface of the limiting blocks 11 is movably connected to the interior of the connecting frame 2.
[0037] The design of the two limit blocks 11 improves the stability of the shear blade 10's movement.
[0038] In some examples, a connecting plate 12 is fixedly connected to the top left side of the connecting frame 2, and a second motor 13 is fixedly installed on the right side of the top of the connecting plate 12. A rotating shaft 14 is fixedly sleeved on the other end of the output shaft of the second motor 13.
[0039] Because the second motor 13 has a self-locking function, it can prevent accidental movement when power is subsequently cut off.
[0040] In some examples, a long rod 15 is fixedly sleeved at the bottom of the outer surface of the rotating shaft 14, and movable rods 16 are hinged at both ends of the long rod 15.
[0041] Since the connection between the rotating shaft 14 and the long rod 15 is fixed, when the rotating shaft 14 rotates, the long rod 15 will also rotate along with it.
[0042] In some examples, the other end of the movable rod 16 is hinged to a movable block 17 located inside the connecting plate 12, and the outer surface of the movable block 17 is movably connected to the interior of the connecting plate 12.
[0043] Since both movable blocks 17 are designed inside the connecting plate 12, they can limit the movement of the two movable blocks 17.
[0044] In some examples, the bottom end of the movable block 17 is fixedly connected to a guide plate 18, and the bottom and top ends of the guide plate 18 are movably connected to the top end of the workbench 1 and the bottom end of the connecting plate 12, respectively.
[0045] The design of the two guide plates 18 enables subsequent guiding operations on the guardrail.
[0046] In some examples, a moving block 19 is movably connected to the left side of the top of the workbench 1. A second pneumatic cylinder 20 is fixedly installed at the top of the moving block 19. The bottom end of the second pneumatic cylinder 20 passes through the moving block 19 and extends to the outside of the top of the inner surface of the moving block 19 and is fixedly connected to a long plate 21. The left side of the long plate 21 is movably connected to the inner surface of the moving block 19.
[0047] Due to the design of the long plate 21, the guardrail can be fixed in the subsequent work, thus making it stable when it is cut.
[0048] In some examples, a third motor 22 is fixedly installed at the top left side of the workbench 1. A lead screw 23 is fixedly sleeved at the other end of the output shaft of the third motor 22. The right end of the lead screw 23 passes through the workbench 1 and extends into the interior of the workbench 1 and is movably connected to the interior of the workbench 1.
[0049] Since both the outer surface of the lead screw 23 and the interior of the worktable 1 are smooth, the frictional loss between the outer surface of the lead screw 23 and the interior of the worktable 1 during rotation can be greatly reduced.
[0050] In some examples, a slider 24 is threaded onto the left side of the outer surface of the lead screw 23. The outer surface of the slider 24 is movably connected to the interior of the worktable 1. The top end of the slider 24 is fixedly connected to the bottom end of the moving block 19. The top right end of the slider 24 is fixedly connected to a pad 25 located inside the worktable 1, and its outer surface is movably connected to the interior of the worktable 1.
[0051] Due to the design of the pad 25, the moving block 19 can still move to the right after the long plate 21 clamps and fixes the guardrail.
[0052] Working principle and usage process of this utility model:
[0053] First, the operator adjusts the distance between the two guide plates 18 according to the specifications of the guardrail. At this time, the second motor 13 should be started, so that the rotating shaft 14 and the long rod 15 rotate, so that the two movable rods 16 move the two guide plates 18 towards each other through the two movable blocks 17, so that the two guide plates 18 can move to the distance required by the operator. Then, the operator pushes the guardrail from the right end of the work platform 1 to the bottom of the long plate 21, so that the left side of the guardrail contacts the left side of the inner surface of the moving block 19. At this time, the operator operates the second pneumatic cylinder 20, so that the long plate 21 moves downward, so that the long plate 21 can press and fix the left side of the top of the guardrail.
[0054] Finally, the operator starts the first motor 4, the first pneumatic cylinder 9, and the third motor 22. The operation of the first motor 4 causes the rotating shaft 5 and the rotating block 6 to rotate, which causes the inner surface of the rotating block 6 to squeeze and push the outer surface of the short shaft 7. This causes the short shaft 7 to drive the pressure plate 8 to move downward, so that the bottom end of the pressure plate 8 will exert downward pressure on the right side of the top of the guardrail. This prevents the guardrail from warping during the subsequent shearing process by the shearing blade 10. The operation of the first pneumatic cylinder 9 causes the shearing blade 10 to move downward, enabling it to shear the guardrail. The operation of the third motor 22 causes the lead screw 23 to rotate, which causes the slider 24 to drive the pad 25 and the moving block 19 to move to the right as a whole, enabling automatic feeding in the subsequent process.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
