Description

Technical Field

[0001] This utility model belongs to the technical field of light pole processing equipment, specifically relating to a light pole cutting device. Background Technology

[0002] Streetlights are an important part of municipal engineering projects. Most common streetlights use round poles that taper from bottom to top. Because the pole has a certain taper, there are no seamless steel pipes that can be used directly. They need to be made by rolling isosceles trapezoidal steel plates into cylinders and then welding them together.

[0003] Before making isosceles trapezoidal steel plates, the entire roll of steel plate needs to be flattened in a roller press before being cut. In order to avoid steel waste, two adjacent isosceles trapezoidal steel plates share a single isosceles side, resulting in the upper base positions of the two adjacent isosceles trapezoidal steel plates being opposite.

[0004] However, before bending, the actual bending points of the upper and lower bottom of the steel plate need to be marked. The bending point positions of the upper bottom and the lower bottom are not the same, which increases the complexity of the bending point marking work. Utility Model Content

[0060] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0061] Please refer to the following: Figures 1 to 6This invention describes a lamp post cutting device. A lamp post cutting device includes a shifting unit 10, a feeding unit 20, and a cutting unit. The shifting unit 10 includes a worktable 101, two clamping assemblies respectively disposed on both sides of the worktable 101 along a first direction, and a driving assembly. The two clamping assemblies are staggered along a second direction. Each clamping assembly includes a fixed plate 102 rotatably connected to the worktable 101, a clamping plate 103 slidably connected to the fixed plate 102, and a first telescopic member 104 fixed between the fixed plate 102 and the clamping plate 103. 103 slides along the direction perpendicular to the surface of the fixed plate 102. The extension direction of the first telescopic member 104 is perpendicular to the first direction. The first telescopic member 104 is a telescopic oil cylinder or hydraulic cylinder. The drive assembly is connected to the fixed plate 102 for driving the fixed plate 102 to rotate around the second direction as the rotation axis. The unloading unit 20 is located between the clamping plate 103 and the fixed plate 102 for disengaging the flipped steel plate from the clamping assembly. The cutting unit is located above the workbench 101 for cutting the steel plate into isosceles trapezoids.

[0062] Specifically, the lamp post cutting device also includes a transfer device corresponding to the clamping assembly. The transfer device is a belt conveyor or a chain conveyor, and the two transfer devices are respectively located on both sides of the workbench 101 along the first direction.

[0063] It should be noted that the number of isosceles trapezoidal steel plates that can be cut can be determined based on the length of the flattened steel coil. If the number of isosceles trapezoidal steel plates cut is even, the cutting unit cuts two isosceles trapezoidal steel plates each time. If the number of isosceles trapezoidal steel plates cut is odd, the cutting unit cuts only one isosceles trapezoidal steel plate in the last cut.

[0064] The lamp post cutting device provided in this embodiment feeds a flattened steel coil between a fixed plate 102 and a clamping plate 103. The first telescopic component 104 is activated, causing the clamping plate 103 to move closer to the fixed plate 102, thereby fixing the steel plate to be cut on the workbench 101. Then, the flattened steel plate is divided into two isosceles trapezoidal steel plates by the cutting unit. After cutting, the fixed plate 102 is flipped by the driving component, thereby flipping the two isosceles trapezoidal steel plates above the corresponding transfer equipment. Then, the first telescopic component 104 is activated, causing the clamping plate 103 to move away from the fixed plate 102, releasing the fixation of the isosceles trapezoidal steel plates. At the same time, the unloading unit 20 transports the isosceles trapezoidal steel plates from between the fixed plate 102 and the clamping plate 103 to the transfer equipment. The transfer equipment then transports the sorted isosceles trapezoidal steel plates to the bending process.

[0065] Compared with the prior art, during cutting, the fixing plate 102 and clamping plate 103 fix the flattened steel plate, so that the steel plate to be cut is fixed on the worktable 101, which improves the cutting accuracy. After cutting, the fixing plate 102 is driven by the drive assembly to flip, so that the two cut isosceles trapezoidal steel plates are flipped to the two sides of the worktable 101 respectively. Thus, the upper and lower bases of the isosceles trapezoidal steel plates on the same side of the worktable 101 are in the same direction. Therefore, the isosceles trapezoidal steel plates in the corresponding bending process are transported by the transfer equipment with the upper and lower bases in the same direction, thereby reducing the complexity of the bending point marking work.

[0066] In some embodiments, see Figure 1 The drive assembly and clamping assembly correspond one-to-one. The drive assembly includes a limiting rod 105, a drive gear 106, a first rotating component, a drive rod 107, a driven gear 108, and an internal gear ring 109. The limiting rod 105 is connected to the fixed plate 102, and the axial direction of the limiting rod 105 is parallel to the second direction. The limiting rod 105 is rotatably connected to the worktable 101, and the limiting rod 105 rotates around its own central axis. The drive gear 106 is fixed to the outer circumference of the limiting rod 105. The first rotating component is drivenly connected to the limiting rod 105 and is used for... The drive limit rod 105 rotates, and the first rotating component is a motor; the drive rod 107 passes through the fixed plate 102 and the two are fixedly connected, and the axial direction of the drive rod 107 is parallel to the axial direction of the limit rod 105; the driven gear 108 is located on the outer periphery of the drive rod 107, and the driven gear 108 is rotatably connected to the drive rod 107. The driven gear 108 rotates about the axial direction of the drive rod 107 as the rotation axis, and the driven gear 108 also meshes with the drive gear 106; the internal gear ring 109 is fixedly connected to the worktable 101, and the internal gear ring 109 also meshes with the driven gear 108.

[0067] The first rotating component starts and drives the limit rod 105 to rotate. The rotation of the limit rod 105 drives the drive gear 106 to rotate. The rotation of the drive gear 106 drives the driven gear 108 to rotate, causing the driven gear 108 to revolve around the internal gear ring 109. As a result, the driven gear 108 drives the drive rod 107 to revolve, which in turn drives the fixed plate 102 to revolve, thereby flipping the isosceles trapezoidal steel plate.

[0068] In some embodiments, see Figure 2 and Figure 3The limiting rod 105 passes through the fixed plate 102 and the two are slidably adapted to each other. The outer wall of the limiting rod 105 is provided with a plurality of limiting grooves 1051 spaced apart along the second direction. The limiting grooves 1051 extend radially along the limiting rod 105. The switching unit 10 also includes a fixing component that is correspondingly provided in the limiting groove 1051. The fixing component includes a snap-fit ​​block 110 and a second telescopic member 111. The snap-fit ​​block 110 is slidably connected to the limiting rod 105. The snap-fit ​​block 110 moves along the extension direction of the limiting groove 1051. After the snap-fit ​​block 110 extends out of the limiting groove 1051, it abuts against the side wall of the fixed plate 102. The second telescopic member 111 is fixed between the limiting rod 105 and the snap-fit ​​block 110. The second telescopic member 111 extends and retracts radially along the limiting rod 105. The second telescopic member 111 is a telescopic oil cylinder or a hydraulic cylinder.

[0069] It should be noted that the snap-fit ​​block 110 is provided with balls on both sides along the axial direction of the limiting rod 105, so that the snap-fit ​​block 110 and the fixing plate 102 are in rolling friction. The balls are used to reduce the friction generated by the fixing plate 102 during rotation.

[0070] The position of the clamping assembly can be changed by adjusting the position of the fixing plate 102 on the limiting rod 105, thereby adapting to the cutting of isosceles trapezoidal steel plates of different specifications. The different specifications of the isosceles trapezoidal steel plates refer to the different widths of the upper and lower bases of the isosceles trapezoid. After the worker moves the fixing plate 102 to the preset position, the second telescopic members 111 located on both sides of the fixing plate 102 are activated, causing the snap-fit ​​block 110 to extend out of the limiting groove 1051 and abut against the side wall of the fixing plate 102, thereby fixing the fixing plate 102 on the limiting rod 105. When it is necessary to adjust the position of the fixing plate 102, the snap-fit ​​block 110 is retracted into the limiting groove 1051 by the retraction of the second telescopic member 111, thereby adjusting the position of the fixing plate 102.

[0071] In some embodiments, see Figure 2 and Figure 4The fixing plate 102 has a first transmission groove 1021 on the side facing the clamping plate 103, and the clamping plate 103 has a second transmission groove 1031 on the side facing the fixing plate 102. The unloading unit 20 includes a first roller 201, a first driving member 202, a second roller 203, and a second driving member 204. The first roller 201 is disposed in the first transmission groove 1021. The first roller 201 is rotatably connected to the fixing plate 102. The rotation axis of the first roller 201 is parallel to a first direction, and the highest point of the first roller 201 is flush with the surface of the fixing plate 102. The moving part 202 is connected to the first roller 201 through a transmission. The first driving part 202 is used to drive the first roller 201 to rotate. The first driving part 202 is a motor. The second roller 203 is disposed in the second transmission groove 1031. The second roller 203 is rotatably connected to the clamping plate 103. The rotation axis of the second roller 203 is parallel to the first direction. The highest point of the second roller 203 is flush with the plate surface of the clamping plate 103. The second driving part 204 is connected to the second roller 203 through a transmission. The second driving part 204 is used to drive the second roller 203 to rotate. The second driving part 204 is a motor.

[0072] When the steel plate to be cut is conveyed between the fixed plate 102 and the clamping plate 103, the first driving component 202 is activated, driving the first roller 201 to rotate, thereby assisting the steel plate to be cut into the space between the fixed plate 102 and the clamping plate 103. After the fixed plate 102 completes its rotation, the first driving component 202 and the second driving component 204 are activated simultaneously, driving the first roller 201 and the second roller 203 to rotate synchronously, so that the isosceles trapezoidal steel plate is conveyed out from between the fixed plate 102 and the clamping plate 103.

[0073] In some embodiments, see Figure 2 , Figure 4 and Figure 5 The fixing plate 102 has a first pressing groove 1022 recessed on the side facing the clamping plate 103, and the clamping plate 103 has a second pressing groove 1032 recessed on the side facing the fixing plate 102. The lamp post cutting device also includes a pressing unit 30. The pressing unit 30 includes a first pressing airbag 301, a first pneumatic component 302, a second pressing airbag 303, and a second pneumatic component 304. The first pressing airbag 301 is disposed in the first pressing groove 1022. The first pneumatic component 302 is connected to the first pressing airbag 301 and is used to blow or inhale air onto the first pressing airbag 301. The first pneumatic component 302 is an air pump. The second pressing airbag 303 is disposed in the second pressing groove 1032. The second pneumatic component 304 is connected to the second pressing airbag 303 and is used to blow or inhale air onto the second pressing airbag 303. The second pneumatic component 304 is an air pump.

[0074] After the fixing plate 102 and clamping plate 103 fix the steel plate to be cut, the first pneumatic component 302 and the second pneumatic component 304 are activated simultaneously. Compressed air is injected into both the first pressing airbag 301 and the second pressing airbag 303, causing both the first pressing airbag 301 and the second pressing airbag 303 to expand. After the first pressing airbag 301 and the second pressing airbag 303 expand, they press against the steel plate, thereby increasing the friction between the steel plate and the fixing plate 102 and clamping plate 103, making it less likely for the position of the steel plate to shift.

[0075] In some embodiments, see Figure 5 The fixing plate 102 has a first adsorption cavity 1023 on the side facing the clamping plate 103, and the first pneumatic component 302 connects the first pressing airbag 301 and the first adsorption cavity 1023; the clamping plate 103 has a second adsorption cavity 1033 on the side facing the fixing plate 102, and the second pneumatic component 304 connects the second pressing airbag 303 and the second adsorption cavity 1033.

[0076] After the first pneumatic component 302 is activated, it compresses the gas in the first adsorption chamber 1023 and pumps it into the first pressing airbag 301, reducing the pressure in the first adsorption chamber 1023. This creates a pressure difference between the first adsorption chamber 1023 and the outside, thus adsorbing the steel plate. After the isosceles trapezoidal steel plate completes its flipping, the first pneumatic component 302 is activated again to draw air from the first pressing airbag 301 into the first adsorption chamber 1023, causing the steel plate to detach from the fixing plate 102. The working principle of the second pneumatic component 304 is the same as that of the first pneumatic component 302, and will not be described again in this application.

[0077] In some embodiments, the clamping unit 30 further includes a first sealing ring and a second sealing ring. The first sealing ring is disposed at the opening of the first adsorption chamber 1023 and is also fixedly connected to the fixing plate 102. The second sealing ring is disposed at the opening of the second adsorption chamber 1033 and is also fixedly connected to the clamping plate 103.

[0078] The sealing effect of the first sealing ring makes the contact between the first adsorption chamber 1023 and the steel plate more compact, thus making it easier to generate a sealing suction force and making the steel plate more stable. The working principle of the second sealing ring is the same as that of the first sealing ring, and will not be described in detail here.

[0079] In some embodiments, see Figure 1 and Figure 6The workbench 101 has multiple transport cavities 1011 arranged in a row along a first direction on its surface. The transport cavities 1011 are arranged in multiple rows along a second direction. The lamp post cutting device also includes a conveying unit 40 that is correspondingly located in each of the transport cavities 1011. The conveying unit 40 includes a rotating frame 401, a third roller 402, and a third driving member 403. The rotating frame 401 is connected to the workbench 101. The third roller 402 is rotatably connected to the rotating frame 401. The rotation axis of the third roller 402 is parallel to the first direction, and the highest point of the third roller 402 is flush with the first roller 201. The third driving member 403 is drivenly connected to the third roller 402 and is used to drive the third roller 402 to rotate. The third driving member 403 is a motor.

[0080] After the steel plate to be cut is conveyed to the workbench 101, the third roller 402 is driven to rotate by the third drive component 403, thereby conveying the steel plate to be cut between the fixed plate 102 and the clamping plate 103. The highest point of the third roller 402 is flush with the highest point of the first roller 201, which can ensure that the steel plate can be accurately fed between the fixed plate 102 and the clamping plate 103 during transportation.

[0081] In some embodiments, see Figure 6 The rotating frame 401 is slidably connected to the worktable 101, and the moving direction of the rotating frame 401 is perpendicular to the table surface of the worktable 101; the conveying unit 40 also includes a third telescopic member 404 fixed between the rotating frame 401 and the worktable 101, the telescopic direction of the third telescopic member 404 is perpendicular to the table surface of the worktable 101, and the third telescopic member 404 is a telescopic oil cylinder or hydraulic cylinder.

[0082] Before adjusting the position of the fixed plate 102, the third telescopic component 404 is activated to retract, and the third roller 402 is drawn into the transport cavity 1011 through the rotating frame 401, so that the third roller 402 will not interfere with the movement of the fixed plate 102; after the position of the fixed plate 102 is adjusted, the third telescopic component 404 is activated to extend, and the third roller 402 is extended through the rotating frame 401 until the third roller 402 is level with the highest point of the first roller 201.

[0083] In some embodiments, see Figure 1 The shifting unit 10 also includes a pressing plate 112 and a second rotating member 113. The pressing plate 112 extends along a first direction, and one end of the pressing plate 112 is rotatably connected to the worktable 101. The rotation axis of the pressing plate 112 is perpendicular to the table surface of the worktable 101. The second rotating member 113 is connected to the pressing plate 112 and is used to drive the pressing plate 112 to rotate. The second rotating member 113 is a motor.

[0084] It should be noted that, Figure 1 The arrow in the image points forward.

[0085] After the first cut, the second rotating component 113 starts to drive the clamping plate 112 to rotate until it comes into contact with the waist of the cut isosceles trapezoidal steel plate and then stops. Then, the conveying unit 40 continues to drive the steel plate to be cut to move forward until the inclined surface of the steel plate to be cut comes into contact with the clamping plate 112 and then stops, so that the cutting unit does not need to be repositioned, thus improving the cutting efficiency.

[0086] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
