Description

Technical Field

[0001] The present application relates to the technical field of steel plate production, and specifically discloses a cutting device for steel plate production. Background Art

[0002] Steel plate cutting machine is a tool for cutting steel plates. Its main function is cutting. It is commonly used for thick and thin steel plate surfaces.

[0003] However, the currently disclosed steel plate cutting machines are double gantry flame plasma cutters and single arm flame plasma cutters, which are recognized by steel plate processing plants and are very convenient equipment for cutting and processing metal workpieces;

[0004] This cutting machine has mature technology, is stable and reliable, but it also has some problems. Due to the fixation of the cutting blade or cutter, the cutting line must be a straight line, but for steel plate cutting, not all steel plate cutting is a straight line cutting. Therefore, the normal operation of the above-mentioned cutting machine is to stop the machine, then change the direction of the entire device, and then start the machine to achieve cutting. This method is very troublesome and is not conducive to the long-term use of the driver. Therefore, in view of the problem that the cutting blade cannot change the angle in a small range, the inventor proposes a cutting device for steel plate production. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the cutting blade in the traditional steel plate cutting machine cannot change the angle in a small range.

[0006] In order to achieve the above object, the present invention provides the following basic scheme:

[0007] A cutting device for steel plate production, comprising

[0008] The outer frame structure includes a bottom plate, a moving wheel arranged on the same side of the bottom plate, a connecting frame and a handle;

[0009] A cutting structure is arranged on the bottom plate, the cutting structure comprising a motor mounting block arranged on the bottom plate, a motor rotatably connected to the motor mounting block, and a cutting blade coaxially connected to the motor;

[0010] A moving assembly for moving the cutting structure up and down, and an angle-changing assembly for cooperating with the moving assembly to change the angle of the cutting structure, wherein the moving assembly and the angle-changing assembly act on the motor mounting block and the motor respectively;

[0011] A tilting component is used to cooperate with the moving component and the variable angle component to make the outer frame structure tilt towards the cutting blade.

[0012] The principles and effects of this basic solution are:

[0013] 1. Compared with the prior art, this device has a simple structure and ingenious design. First, this device has the functions of a traditional mobile steel plate cutting machine, can achieve smooth movement, and can also be hand-pushed, and also has good portability. Secondly, compared with traditional steel plate cutting machines, this device has a simpler structure and has certain advantages in production or mass production.

[0014] 2. Compared with the prior art, the present device can change the angle of the steel plate cutting machine without changing the direction of the device itself, so as to better cut irregular steel plates. The present device is provided with an angle-changing component, which changes the position of the motor in a small range through the angle-changing component, so that the angle of the motor changes, thereby changing the position of the cutting blade.

[0015] 3. Compared with the prior art, the present device is not only provided with a variable angle component, but also with a moving component. The height of the cutting blade is changed by the moving component, so that the cutting depth of the cutting blade can be determined artificially, and the range of action is wider. In order to enhance the variable angle and moving functions of the present device, the moving component and the variable angle component in the present device can cooperate with each other and adopt the same switching component to act, and realize the functional embodiment of the moving component and the variable angle component by switching the switching component in different modes. It is more ingenious in principle, simpler in structure, and easier to use in operation. By changing the angle of the motor, the problem that the cutting blade in the traditional steel plate cutting machine cannot change the angle in a small range is solved.

[0016] 4. Compared with the prior art, in order to enhance the angle variation, the device creatively designs a tilting component. The core of the tilting component lies in the neglected wheel. By improving the wheel, the wheel can be tilted on the same side, so that the cutting blade can cut better and complete arc cutting.

[0017] 5. Compared with the prior art, the moving component, the variable angle component and the tilting component in the device cooperate with each other and act on the cutting blade, so that the cutting blade has the function of cutting at different depths, irregular cutting and arc or quasi-arc cutting without changing the posture of the entire device, making the function of the cutting blade more obvious and the effect better.

[0018] Furthermore, a compression spring is provided at the bottom of the motor mounting block, and the compression spring is connected to the bottom plate. A rotating rod for rotating the motor is provided at the connection between the motor mounting block and the motor.

[0021] Furthermore, the angle-variable assembly includes a second gear meshing with the driving gear and a sliding rack meshing with the second gear, and the sliding rack is used for deflection of the motor.

[0022] Furthermore, the traction assembly includes an annular groove opened on the connecting frame, a sliding block arranged in the annular groove and slidably connected to the annular groove, and a traction rod arranged on the driving gear, the free end of the traction rod is detachably connected to the sliding block, the driving gear is engaged with the first gear to realize the lifting and lowering of the cutting blade, and the driving gear is engaged with the second gear to realize the changing angle of the cutting blade.

[0023] Furthermore, the tilting assembly includes an inflatable wheel symmetrically arranged with the moving wheel and a support frame for supporting the inflatable wheel. The support frame and the outer wheel of the inflatable wheel are wrapped with air bags.

[0035] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0036] The figure marks in the drawings of the specification include: dustproof component 1, water tank 101, protection box 102, sliding rack 1021, hinged frame 1022, rack surface 1023, mounting rod 1024, moving wheel 3, inflatable wheel 4, bottom plate 5, connecting frame 6, grasping block 7, handle member 8, rotating handle 9, wheel hub 10, first gear 11, threaded rod 12, connecting plate 13, motor 14, splashproof shell 15, circular saw blade 16, motor mounting block 17, water outlet 18, airbag 19, support frame 20, main rod 21, driving gear 22, first limit plate 23, second limit plate 24, auxiliary rod 25, second gear 26, opening switch 27, traction rod 28, annular groove 29, sliding block 30, snap-on teeth 31, hinge point 32, snap-on point 33, rotating rod 34.

[0037] Implementation example Figure 1-Figure 7 As shown:

[0038] A cutting device for steel plate production, comprising

[0039] The outer frame structure includes a bottom plate 5, a moving wheel 3 arranged on the same side of the bottom plate 5, a connecting frame 6 and a handle member 8. The handle member 8 includes a gripping handle and a gripping block 7 for connecting the gripping handle.

[0040] Specific: such as Figure 1As shown, the connecting frame 6 is fixedly connected to the bottom plate 5, and the inner side of the connecting frame 6 is hollowed out for installation of subsequent components. The handle 8 adopts a horizontal push rod design to facilitate force. Figure 1 As shown, the moving wheel 3 is arranged on the right side of the base plate 5, which is different from the left side of the base plate 5. Since the cutting blade is arranged on the left side, the moving wheel 3 needs to be arranged on the right side, so that the base plate 5 can be tilted toward the cutting blade in a small range in the future.

[0041] A cutting structure is arranged on the bottom plate 5, the cutting structure comprising a motor mounting block 17 arranged on the bottom plate 5, a motor 14 rotatably connected to the motor mounting block 17, and a cutting blade coaxially connected to the motor 14;

[0042] Regarding the cutting structure, a moving component is required to be used to move the cutting structure up and down: a compression spring is provided at the bottom of the motor mounting block 17, and the compression spring is connected to the bottom plate 5. A rotating rod 34 for rotating the motor 14 is provided at the connection between the motor mounting block 17 and the motor 14.

[0043] Specific: such as Figure 1 , Figure 2 and Figure 6 As shown, the cutting blade includes a cutting blade coaxially connected to the motor 14, including a splashproof shell 15 and a circular saw blade 16 located inside the splashproof shell 15, and the moving component includes a rotatable threaded rod 12 arranged on the connecting frame 6, a first gear 11 sleeved on the threaded rod 12 and a connecting plate 13 threadedly connected to the threaded rod 12, and the free end of the connecting plate 13 is fixed to the motor mounting block 17 to achieve compression and resetting of the compression spring and thus change the height of the cutting blade. In this process, since the connecting plate 13 is directly connected to the motor mounting block 17, there may be an unstable rise of the motor 14. Therefore, a telescopic rod for assisting the connecting plate 13 to move up and down is provided at the bottom of the connecting plate 13, and the bottom of the telescopic rod is fixed to the base plate 5.

[0044] The above process requires the use of a switching assembly, which includes a rotating handle 9, a main rod 21 coaxially connected to the rotating handle 9, a driving gear 22 slidably connected to the main rod 21, and a traction assembly for moving the driving gear 22 up and down; the main rod 21 is located on the upper and lower sides of the driving gear 22 and is provided with a first limit plate 23 and a second limit plate 24, the first limit plate 23 and the second limit plate 24 are used to quickly position the driving gear 22 to engage the first gear 11 and the second gear 26, and the second gear 26 is provided with a sub-rod 25, and the upper part of the sub-rod 25 is connected to the connecting frame 6.

[0045] Specifically: after the handle 9 is rotated, the driving gear 22 is rotated. Due to the driving gear 22 and the first gear 11, the threaded rod 12 is rotated, so that the connecting plate 13 moves upward or downward, and then the motor mounting block 17 moves upward or downward, thereby changing the position of the motor 14. When the position of the motor 14 changes, for the cutting blade, similarly, the position of the cutting blade is also changing. Through this operation, the action depth of the cutting blade can be artificially controlled.

[0046] A variable angle component is used in conjunction with the moving component to change the angle of the cutting structure. The moving component and the variable angle component act on the motor mounting block 17 and the motor 14 respectively. A switching component for switching between the variable angle component and the moving component is provided between the variable angle component and the moving component.

[0047] Specific: such as Figure 2 , Figure 3 and Figure 4 As shown:

[0048] A tilting component is used to cooperate with the moving component and the angle-changing component to make the outer frame structure tilt toward the cutting blade.

[0049] The angle-changing assembly includes a second gear 26 that can be meshed with the driving gear 22 and a sliding rack 1021 that is meshed with the second gear 26. The sliding rack 1021 is used for the deflection of the motor 14. The traction assembly includes an annular groove 29 opened on the connecting frame 6, a sliding block 30 arranged in the annular groove 29 and slidably connected to the annular groove 29, and a traction rod 28 arranged on the driving gear 22. The free end of the traction rod 28 is detachably connected to the sliding block 30. The driving gear 22 is meshed with the first gear 11 to realize the lifting and lowering of the cutting blade, and the driving gear 22 is meshed with the second gear 26 to realize the angle change of the cutting blade.

[0050] Specifically: manually pull the traction rod 28 upward to make the active gear 22 mesh with the first gear 11 to achieve the lifting of the cutting blade. Similarly, no human action is applied to the traction rod 28, so that the traction rod 28 moves downward, and then the active gear moves downward to mesh with the second gear 26. At this time, there may be a problem that the active gear 22 and the first gear 11 and the second gear 26 are not aligned. Therefore, it is necessary to manually slightly rotate the main rod 21 so that the active gear 22 can align the teeth of the first gear 11 and the second gear 26 to achieve gear meshing.

[0051] When the driving gear 22 is meshed with the first gear 11, the traction rod 28 moves upward, and a latching tooth 31 is provided inside the sliding block 30. A hinge point 32 is formed between the latching tooth 31 and the annular groove 29, which is used to change the angle of the latching tooth 31. Then, as shown in FIG. Figure 4As shown, a clamping point 33 is provided on the traction rod 28, and the clamping tooth 31 is clamped in the clamping point 33, thereby fixing the traction rod 28. When the main rod 21 rotates, due to the design of the annular groove 29, the traction rod 28 will not affect the rotation of the driving gear 22.

[0052] Regarding the meshing of the driving gear 22 and the second gear 26, the driving gear 22 is moved downward by the pulling rod 28 to mesh with the second gear 26, and then drives the second gear 26 to rotate. Figure 7 As shown, after driving the sliding rack 1021 to move, the sliding rack 1021 is used for the deflection of the motor 14;

[0053] Specifically: a sliding rack 1021 is provided with a fully free articulated frame 1022 on one side thereof for fixing, a smooth surface and a rack surface 1023 are provided on the side of the sliding rack 1021 away from the articulated frame 1022, a mounting rod 1024 is provided on the smooth surface, the mounting rod 1024 is connected to the bottom of the motor 14, the rack surface 1023 is meshed with the second gear 26 to realize the sliding of the sliding rack 1021, when the sliding rack 1021 moves back and forth, the mounting rod 1024 moves back and forth, since the motor mounting block 17 and the motor 14 are rotatably connected, a rotating rod 34 is provided at the connection between the motor mounting block 17 and the motor 14, then the mounting rod 1024 acts on the motor 14, which can cause deflection, and when the motor 14 occurs, a deflection angle can occur for the cutting blade, thereby allowing the cutting blade to complete irregular cutting.

[0054] like Figure 1 As shown, a dustproof component 1 is provided on the base plate 5, and the dustproof component 1 includes a water tank 101 and a protection box 102. The protection box 102 is used to protect the sliding rack 1021 in the variable angle component and for the installation of the articulated frame 1022. A water outlet 18 is provided on the outer side of the water tank 101 near the cutting blade.

[0055] Regarding the up and down movement of the motor mounting block 17 and the forward and backward deflection of the motor 14, the interference problem of the two movements is caused by the following Figure 7 As shown, the sliding rack 1021 is used to fix a side with a full-freedom articulated frame 1022. When the motor mounting block 17 moves up and down, it will act on the articulated frame 1022 without affecting the mounting rod 1024. Similarly, when the motor 14 deflects, causing the motor 14 to deflect, it will not affect the motor mounting block 17. A rotating rod with rotational freedom is provided between the motor mounting block 17 and the motor 14.

[0056] In order to enhance the angle change, the device creatively designs a tilting component, such as Figure 4 and Figure 5As shown, the tilting assembly includes an inflatable wheel 4 symmetrically arranged with the moving wheel 3 and a support frame 20 for supporting the inflatable wheel 4. The support frame 20 and the outer wheel of the inflatable wheel 4 are wrapped with air bags 19. An air pump and an air pump are provided under the bottom plate 5 to realize the inflation and deflation of the air bags 19.

[0057] Specifically: the vacuum pump and the air pump are both automatic standard parts, and the opening switch 27 is set at Figure 2 The vacuum pump and the air pump are turned on and off by using the opening switch 27. The outer tube of the inflatable wheel 4 is an air bag 19, and the inner tube is a metal hub 10. The surface of the metal hub 10 is provided with an anti-friction layer. When the air bag 19 is deflated, the entire device tilts toward the cutting blade, thereby making it easier for the cutting blade to contact the ground. Then, when the device is pushed by hand, the trajectory of the cutting blade is an arc. This arc, combined with the variable angle component, can solve the problem that the cutting blade in the traditional steel plate cutting machine cannot change the angle in a small range.

[0058] There is no need to worry about the wear of the pneumatic wheel 4 , because the surface of the metal hub 10 is provided with an anti-friction layer, temporarily grounding the hub 10 of the pneumatic wheel 4 does not affect the subsequent use of the pneumatic wheel 4 .

[0059] Specific implementation process:

[0060] When the cutting disc in the device is not in use, the cutting disc will not affect the device. If the cutting disc is needed, if it is a straight line cutting, the moving component alone can be used. If irregular cutting or arc or quasi-arc cutting is required, the variable angle component and the tilting component are required at the same time. If the angle is changed in a small range for cutting, the variable angle component can be started alone for cutting. The moving component, the variable angle component and the tilting component in the device cooperate with each other and act on the cutting disc, so that the cutting disc has the function of cutting at different depths on the steel plate, and the irregular cutting and arc or quasi-arc cutting without changing the posture of the entire device makes the effect of the cutting disc more obvious and the effect is better.

[0061] The device solves the problem that the cutting blade in the traditional steel plate cutting machine cannot change the angle within a small range.

[0062] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
