Description

Technical Field

[0001] This utility model relates to the field of steel structure production technology, specifically a shearing machine for steel structure production. Background Technology

[0002] Steel structures are structures made of steel materials. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components or parts are usually connected by welds, bolts or rivets. In the production process of steel structures, shearing machines are required to shear the steel plates.

[0003] Chinese Utility Model Patent Application No. 202421621289.4 discloses a thick plate shearing and fixing device. The utility model describes the following: "This utility model provides a thick plate shearing and fixing device. In use, a medium-thick plate is placed on a worktable and pushed forward to a designated position. The motor is started, driving a transmission rod to rotate. The transmission rod drives a first helical gear to rotate, which in turn drives a second and third helical gear to rotate. The second and third helical gears respectively drive a first and a second lead screw to rotate. The rotation of the first and second lead screws causes the clamping member to move downwards, thereby clamping the medium-thick plate. Part of the medium-thick plate also overlaps on a shearing bracket. After the medium-thick plate is clamped, a hydraulic press is started, driving a cutter downwards to shear the medium-thick plate. This thick plate shearing and fixing device provides a good fixing effect for the medium-thick plate, resulting in a better quality shear cut."

[0004] In this thick plate shearing and fixing device, the operator first places the steel plate on the top of the workbench and then pushes the steel plate to the designated position. Although the pulley rotates under force, reducing some friction, when the protrusion positions the top of the steel plate, one side of the steel plate will tilt along the pulley. Furthermore, the steel plate is not limited during movement and may be in a tilted state, which may cause the shearing point of the steel plate to tilt, reducing the shearing effect. Improvement is needed. Therefore, a shearing machine for steel structure production is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a shearing machine for steel structure production, which has advantages such as good shearing effect and solves the problem that the steel plate may tilt at the shearing point, reducing the shearing effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shearing machine for steel structure production, comprising a worktable, a shearing mechanism and a horizontal plate connected to the worktable, an adjustment mechanism connected to the horizontal plate, a limit mechanism provided on the adjustment mechanism, and a positioning mechanism connected to the limit mechanism.

[0007] Furthermore, the shearing mechanism includes a frame, which is fixedly connected to the top of the workbench. A hydraulic cylinder is fixedly installed on the top of the frame, and the output end of the hydraulic cylinder passes through the frame and is fixedly installed with a lifting plate. A blade is fixedly installed at the bottom of the lifting plate.

[0008] Furthermore, a lifting block extending into the frame body is fixedly installed on the side wall of the lifting plate, and a lifting groove matching the lifting block is opened on the inner side wall of the frame body.

[0009] Furthermore, multiple diagonal braces are fixedly installed between the bottom of the horizontal plate and the side wall of the workbench. The multiple diagonal braces are divided into two groups, and the diagonal braces in each group are evenly and equidistantly distributed.

[0010] Furthermore, the adjustment mechanism includes a first chamber, which is fixedly connected to the bottom of the horizontal plate. A first motor is fixedly installed on the outer wall of the first chamber. The output end of the first motor passes through the first chamber and is fixedly installed with a first threaded rod. The side of the first threaded rod away from the output end of the first motor is rotatably connected to the inner wall of the first chamber through a first bearing. A first threaded sleeve is installed on the external thread of the first threaded rod. Two first moving rods that pass through the first chamber and the horizontal plate and extend to the top of the horizontal plate are symmetrically fixedly installed on the surface of the first threaded sleeve. The tops of the two first moving rods are fixedly connected to the bottom of the second chamber.

[0011] Furthermore, the limiting mechanism includes a second compartment, which is slidably connected to the top of the horizontal plate. A second motor is fixedly installed on the outer wall of the second compartment. The output end of the second motor passes through the second compartment and is fixedly installed with a second threaded rod. The side of the second threaded rod away from the output end of the second motor is rotatably connected to the inner wall of the second compartment through a second bearing. The outer side of the second threaded rod has two sections of threads with opposite directions and equal lengths. A second threaded sleeve is threadedly installed on the outer side of both sections of the second threaded rod. A second moving rod that passes through and extends to the outside of the second compartment is fixedly installed on the surface of each of the two second threaded sleeves. A clamping plate is fixedly installed on the side wall of each of the two second moving rods.

[0012] Furthermore, a movable block extending into the interior of a horizontal plate is fixedly installed at the bottom of the second compartment, and a movable groove matching the movable block is provided at the top of the horizontal plate.

An electric push rod is fixedly installed on the top of the connecting plate, and the output end of the electric push rod passes through the connecting plate and is fixedly installed with the positioning plate.

[0014] Furthermore, a slider extending into the second compartment is fixedly installed on the side wall of the positioning plate, and a groove matching the slider is provided on the outer side wall of the second compartment.

[0015] Furthermore, multiple grooves are provided on the top of the workbench and the top of the horizontal plate.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects: This shearing machine for steel structure production consists of a worktable, shearing mechanism, horizontal plate, adjusting mechanism, limiting mechanism, positioning mechanism, and circular rollers. The operator first places the steel plate on top of the worktable. Then, the limiting mechanism aligns the steel plate with its sides, and the positioning mechanism positions the top of the steel plate. The adjusting mechanism then moves the limiting mechanism, positioning mechanism, and steel plate linearly, bringing the shearing section of the steel plate directly below the shearing mechanism. The circular rollers rotate under pressure, reducing friction. Finally, the shearing mechanism shears the steel plate. This design ensures the steel plate is horizontal during positioning and is limited during movement, preventing tilting and improving the shearing efficiency. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] Example 1 Please see Figure 1 In this embodiment, a shearing machine for steel structure production includes a workbench 1, a shearing mechanism 2 and a horizontal plate 3 connected to the workbench 1, an adjustment mechanism 4 connected to the horizontal plate 3, a limit mechanism 5 provided on the adjustment mechanism 4, and a positioning mechanism 6 connected to the limit mechanism 5.

[0021] Specifically, the worker first places the steel plate on top of the workbench 1, then uses the limiting mechanism 5 to fit against both sides of the steel plate, and uses the positioning mechanism 6 to position the top of the steel plate. Then, the adjusting mechanism 4 drives the limiting mechanism 5, the positioning mechanism 6, and the steel plate to move linearly, so that the part of the steel plate to be sheared is moved directly below the shearing mechanism 2. The roller 7 rotates under force, reducing some of the friction. Finally, the shearing mechanism 2 is used to shear the steel plate. Not only is the steel plate in a horizontal state when the top of the steel plate is positioned, but the steel plate is also limited during the movement, making it less likely to tilt. The part of the steel plate to be sheared is less likely to tilt, thus improving the shearing effect.

[0022] Please see Figure 2 In this embodiment, the shearing mechanism 2 includes a frame 21, which is fixedly connected to the top of the workbench 1. A hydraulic cylinder 22 is fixedly installed on the top of the frame 21. The output end of the hydraulic cylinder 22 passes through the frame 21 and is fixedly installed with a lifting plate 23. Two lifting blocks extending into the frame 21 are symmetrically fixedly installed on the side wall of the lifting plate 23. A lifting groove matching the lifting block is opened on the inner side wall of the frame 21. A blade 24 is fixedly installed at the bottom of the lifting plate 23. A through hole matching the blade 24 is opened on the top of the workbench 1.

[0023] Specifically, by activating the hydraulic cylinder 22, the hydraulic cylinder 22 drives the lifting plate 23 and the blade 24 to move downwards, and the blade 24 cooperates with the through hole to shear the steel plate.

[0024] Please see Figure 2 In this embodiment, six diagonal rods are fixedly installed between the bottom of the horizontal plate 3 and the side wall of the workbench 1. The angle between the six diagonal rods and the horizontal plate 3 is 30°. The six diagonal rods are divided into two groups, and each group of diagonal rods is evenly and equidistantly distributed.

[0025] Specifically, six diagonal braces support the horizontal plate 3, enhancing the stability of the connection between the workbench 1 and the horizontal plate 3.

[0026] Please see Figure 3 In this embodiment, the adjustment mechanism 4 includes a first chamber 41, which is fixedly connected to the bottom of the horizontal plate 3. A first motor 42 is fixedly installed on the outer wall of the first chamber 41. The output end of the first motor 42 passes through the first chamber 41 and is fixedly installed with a first threaded rod 43. The side of the first threaded rod 43 away from the output end of the first motor 42 is rotatably connected to the inner wall of the first chamber 41 through a first bearing. A first threaded sleeve 44 is installed on the outer thread of the first threaded rod 43. Two first moving rods 45 are symmetrically fixedly installed on the surface of the first threaded sleeve 44, which pass through the first chamber 41 and the horizontal plate 3 and extend to the top of the horizontal plate 3. The side wall of the first chamber 41 and the top of the horizontal plate 3 are both provided with first moving holes that match the first moving rods 45.

[0027] Specifically, by turning on the first motor 42, the first motor 42 drives the first threaded rod 43 to rotate, the first threaded rod 43 drives the first threaded sleeve 44 to rotate, and the first threaded sleeve 44 drives the two first moving rods 45 to move linearly.

[0028] Please see Figure 4-5 In this embodiment, the limiting mechanism 5 includes a second chamber 51, which is fixedly connected to the top of two first moving rods 45. Two moving blocks extending into the interior of the horizontal plate 3 are fixedly installed at the bottom of the second chamber 51. The top of the horizontal plate 3 is provided with a moving groove that matches the moving blocks. A second motor 52 is fixedly installed on the outer wall of the second chamber 51. The output end of the second motor 52 passes through the second chamber 51 and is fixedly installed with a second threaded rod 53. The side of the second threaded rod 53 away from the output end of the second motor 52 is rotatably connected to the inner wall of the second chamber 51 through a second bearing. The outer side of the second threaded rod 53 is provided with two threads of opposite directions and equal lengths. The pitch of the threads at both ends is equal. A second threaded sleeve 54 is threadedly installed on the outer side of both threads of the second threaded rod 53. A second moving rod 55 that passes through and extends to the outside of the second chamber 51 is fixedly installed on the surface of both second threaded sleeves 54. A clamping plate 56 is fixedly installed on the side wall of both second moving rods 55.

[0029] Specifically, by turning on the second motor 52, the second motor 52 drives the second threaded rod 53 to rotate, and the second threaded rod 53 drives the two second threaded sleeves 54, the two second moving rods 55 and the two clamping plates 56 to move relative to each other, so that the two clamping plates 56 are in contact with the two sides of the steel plate.

[0030] Please see Figure 4In this embodiment, the positioning mechanism 6 includes a connecting plate 61, which is fixedly connected to the outer side wall of the first compartment 41. An electric push rod 62 is fixedly installed on the top of the connecting plate 61. The output end of the electric push rod 62 passes through the connecting plate 61 and is fixedly installed with a positioning plate 63. Two sliders extending into the interior of the second compartment 51 are fixedly installed on the side wall of the positioning plate 63. The outer side wall of the second compartment 51 is provided with a groove that matches the slider.

[0031] Specifically, by activating the electric push rod 62, the electric push rod 62 drives the positioning plate 63 to move downward, so that the positioning plate 63 positions the top of the steel plate.

[0032] The working principle of the above embodiments is as follows: The worker first places the steel plate on top of workbench 1, then turns on the second motor 52. The second motor 52 drives the second threaded rod 53 to rotate, which in turn drives the two second threaded sleeves 54, the two second moving rods 55, and the two clamping plates 56 to move relative to each other, so that the two clamping plates 56 are in contact with the sides of the steel plate. Then, the electric push rod 62 is turned on, which drives the positioning plate 63 to move downward, positioning the top of the steel plate. Finally, the first motor 42 is turned on, which drives the first threaded rod 43 to rotate, which in turn drives the second threaded sleeve 54, the two second moving rods 55, and the two clamping plates 56 to move relative to each other, so that the two clamping plates 56 are in contact with the sides of the steel plate. A threaded sleeve 44 rotates, driving two first moving rods 45, a second chamber 51, two clamping plates 56, a positioning plate 63, and a steel plate to move linearly, so that the shearing point of the steel plate is moved directly below the blade 24. Finally, the hydraulic cylinder 22 is activated, driving the lifting plate 23 and the blade 24 to move downward. The blade 24, in conjunction with the through hole, shears the steel plate. Not only is the top of the steel plate positioned horizontally, but the steel plate is also limited during movement, making it less prone to tilting. The shearing point of the steel plate is less likely to tilt, thus improving the shearing effect.

[0033] Example 2 The difference between Example 2 and Example 1 is that in this example, multiple grooves are provided on the top of the workbench 1 and the top of the horizontal plate 3. The inner sidewalls of the multiple grooves are rotatably mounted with rollers 7 through a third bearing. The tops of the multiple rollers 7, the top of the workbench 1, and the top of the horizontal plate 3 are all flush.

[0034] Specifically, the steel plate drives the roller 7 to rotate during the movement, which reduces some of the friction.

[0035] The working principle of the above embodiments is as follows: The worker first places the steel plate on top of workbench 1, then turns on the second motor 52. The second motor 52 drives the second threaded rod 53 to rotate, which in turn drives the two second threaded sleeves 54, the two second moving rods 55, and the two clamping plates 56 to move relative to each other, so that the two clamping plates 56 fit against the sides of the steel plate. Then, the electric push rod 62 is turned on, which drives the positioning plate 63 to move downward, positioning the top of the steel plate. Finally, the first motor 42 is turned on, which drives the first threaded rod 43 to rotate, which in turn drives the first threaded sleeve 44 to rotate. The first threaded sleeve 44 drives the two first moving rods 45, the second chamber 51, the two clamping plates 56, the positioning plate 63, and the steel plate to move linearly, so that the shearing part of the steel plate is moved to directly below the blade 24. The roller 7 rotates under force, reducing some of the friction. Finally, the hydraulic cylinder 22 is activated, which drives the lifting plate 23 and the blade 24 to move downward. The blade 24, in conjunction with the through hole, shears the steel plate. Not only is the top of the steel plate positioned horizontally, but the steel plate is also limited during movement, making it less prone to tilting. The shearing part of the steel plate is less likely to tilt, thus improving the shearing effect.
