Description

Technical Field

[0001] The invention relates to the technical field of wire mesh cutting, in particular to a pedal cutting device for scaffolding processing. Background Art

[0002] The scaffolding includes vertical poles, horizontal poles, diagonal poles, herringbone supports, support platforms, pedals, etc., wherein the pedals are welded by a wire mesh and a frame. Before the wire mesh is welded to the frame, the wire mesh needs to be cut into a specified size. However, when the wire mesh is cut using an existing cutting device, the position of the cutting knife cannot be adjusted, and the cutting device cannot actively adjust the position of the wire mesh, resulting in the cutting position of the cutting knife being unable to align with the connection of the wire mesh, causing the edges of the cut wire mesh to be messy after cutting, causing the edges of two adjacent layers of wire mesh to be entangled with each other during the stacking process, affecting subsequent use; in order to reduce the occurrence of the above problems, the position of the wire mesh is usually adjusted by the operator, which will lead to low efficiency in mass production, and there will also be errors in manual adjustment, and it is impossible to ensure that the cutting position is always aligned with the connection of the wire mesh, which will affect the subsequent use of the cut wire mesh.

DETAILED DESCRIPTION

[0020] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Through research, it is found that the existing wire mesh cutting device cannot ensure that the cutting knife is aligned with the connection of the wire mesh when cutting the wire mesh. In order to ensure the flatness of the wire mesh after cutting, the operator will adjust the position of the wire mesh. In this process, the rolled wire mesh will first be cut into wire mesh preforms of fixed length (to reduce the impact of wire mesh bending when cutting the rolls). Then, by adjusting the position of the preform, the edges are cut and trimmed to ensure that the edges of the wire mesh are flat. Then, the preform is cut to a fixed length. In this process, the operator is also required to subjectively judge the position of the wire mesh to ensure that the cutting knife is always aligned with the connection of the wire mesh, which will lead to low cutting efficiency.

[0022] Example 1: A pedal cutting device for scaffolding processing, Figure 1-Figure 4As shown, it includes a support frame 1; a telescopic module 2, which is installed on the support frame 1, and the telescopic end of the telescopic module 2 is fixedly connected to the mounting plate 3; a transition plate 4, which is arranged on the mounting plate 3; a cutting knife 5, which is slidably connected to the transition plate 4; a cutting table 6, which is arranged on the support frame 1, and the mounting plate 3 is installed with a displacement sensor 311, and the displacement sensor 311 is used to detect the distance between the mounting plate 3 and the cutting table 6; a mounting frame 7, which has a plurality of spaced apart mounting frames, which are all fixedly connected to the transition plate 4 and are slidably connected to the cutting table 6, and the cutting table 6 is slidably connected to the sliding plates 8 of the same number as the mounting frames 7, and the sliding plates 8 are slidably connected to adjacent mounting frames 7; a stabilizing mechanism, which has two, which are both arranged on the mounting plate 3, and are used to flatten the wire mesh; a detection and positioning mechanism, whose number is consistent with the number of sliding plates 8, which are respectively arranged on adjacent sliding plates 8, and are used to detect the position of the wire mesh and adjust the position of the cutting knife 5.

[0023] In the above scheme, the purpose is to fine-tune the position of the cutting knife 5 according to the position of the wire mesh, so that the blade of the cutting knife 5 is always aligned with the connection of the wire mesh; the support frame 1 can be provided with an electric slide rail and an electric slider, and the telescopic module 2 is fixedly connected to the electric slider, so that it is convenient to adjust the position of the telescopic module 2, and it is convenient to adjust the position of the cutting knife 5, so that the present device can be applied to any type of wire mesh; the telescopic module 2 has the same function as the existing electric push rod, and is used to drive the cutting knife 5 to move downward; the mounting frame 7 has two front and rear symmetrically distributed, and in this embodiment, the mounting frame 7 slides in the vertical direction along the cutting table 6; in this embodiment, the upper side of the cutting table 6 is fixedly connected to a limiting block, so that the wire mesh is limited.

[0024] Comparison Figure 1-Figure 3 As shown, the stabilizing mechanism includes: two swing members 21 , both of which are rotatably connected to the mounting plate 3 , and a first elastic member is arranged between the swing member 21 and the mounting plate 3 ; and a flattening roller 22 , which is rotatably connected between the two swing members 21 .

[0025] In the above scheme, a method for flattening the wire mesh is provided. The swing member 21 is composed of two swing rods and a square plate, the swing rods are rotatably connected to the square plate, the two swing rods are parallel, and the two swing rods, the square plate and the mounting plate 3 together form a parallelogram structure. When the flattening roller 22 is squeezed, the swing member 21 will deflect; the first elastic member on the swing member 21 is a torsion spring (between the swing rod and the mounting plate 3). In the initial state, there is an angle between the swing member 21 and the vertical plane, which facilitates its deflection after being squeezed.

[0026] Comparison Figure 3-Figure 7As shown, the detection and positioning mechanism includes: a driving push rod 31, which is installed on the sliding plate 8; a first rod 32, which is slidably connected to the sliding plate 8 and fixed to the telescopic end of the driving push rod 31, the first rod 32 is slidably connected to the second rod 33, the second rod 33 is slidably connected to the sliding plate 8, and the second rod 33 is provided with a positioning member 34; a driving component, which is arranged on the sliding plate 8 and is used to adjust the position of the cutting knife 5.

[0027] In the above scheme, a method for detecting the position of the wire mesh is proposed, so as to determine the position of the connection on the wire mesh, so as to facilitate the adjustment of the position of the cutting knife 5; the displacement sensor 311 is an existing device, and its internal structure is not described here. When the displacement sensor 311 detects that the mounting plate 3 reaches the specified position (both the two flattening rollers 22 are in contact with the wire mesh, and the cutting knife 5 is not in contact with the wire mesh), the telescopic end of the driving push rod 31 is controlled to extend; the driving push rod 31 is an existing active telescopic device, on which an external sensor and a feedback control system are arranged to ensure that during the extension of the telescopic end of the driving push rod 31, when the resistance of the telescopic end reaches a specified value (i.e., it contacts the connection of the wire mesh), the telescopic end stops extending.

[0028] Comparison Figure 7 As shown, the positioning member 34 includes a mounting rod 341, two sliding rods 342 and two extrusion rods 343. The two sliding rods 342 are respectively slidably connected to the two sides of the mounting rod 341, and the two extrusion rods 343 are respectively slidably connected to the adjacent sliding rods 342. The mounting rod 341 is fixedly connected to the second rod 33.

[0029] In the above scheme, the purpose is to further limit the composition of the positioning member 34; the two sliding rods 342 can move left and right, thereby adjusting the positions of the two squeezing rods 343, so that the positioning member 34 can be suitable for wire meshes of different sizes; the distance between the two squeezing rods 343 away from the adjacent mounting rods 341 is an integer multiple of the length of the short diagonal on a single diamond grid of the wire mesh; the position of the squeezing rod 343 away from the mounting rod 341 is set as a triangular block; two threaded rods are threadedly connected to the mounting rod 341, and the threaded rods are used to squeeze the adjacent sliding rods 342 so that the sliding rods 342 cannot move; a threaded rod is also threadedly connected to the sliding rod 342, and the threaded rod is used to squeeze and limit the adjacent squeezing rod 343, so that the squeezing rod 343 cannot move.

[0030] Comparison Figure 3-Figure 6 As shown, the driving assembly includes: an elastic telescopic rod 35, which is installed on the sliding plate 8, and its telescopic end is slidably connected to the second rod 33; a first telescopic rod 36, which is fixed to the transition plate 4, and its telescopic end is fixed to the cutting knife 5, and a first conduit 37 is connected between the fixed part of the first telescopic rod 36 and the fixed part of the elastic telescopic rod 35.

[0031] In the above solution, a method of driving the cutting knife 5 to move is proposed; the fixed portion of the elastic telescopic rod 35, the fixed portion of the first telescopic rod 36 and the first conduit 37 are all filled with hydraulic oil.

[0032] Working process: When the device is used to cut the wire mesh (the wire mesh to be cut is a pre-processed wire mesh, that is, the edges of the wire mesh are all in a flush state), firstly, the distance between the two sliding rods 342 on the same mounting rod 341 is adjusted according to the model of the wire mesh (that is, the adjacent threaded rods are loosened, and then the two adjacent sliding rods 342 are moved relative to each other, and the sliding rods 342 drive the extrusion rods 343 to move until the distance between the two extrusion rods 343 away from the adjacent mounting rods 341 is the whole length of the short diagonal line on a single diamond grid of the wire mesh). When the distance between the sliding rod 342 and the extruding rod 343 is several times greater, tighten the threaded rod, and at the same time, adjust the distance between the sliding rod 342 and the extruding rod 343 according to the same principle), then adjust the position of the telescopic module 2 according to the required cutting length, so that the horizontal distance between the telescopic module 2 and the upper limit block of the cutting table 6 is consistent with the required length, and the side of the wire mesh contacts the upper limit block of the cutting table 6, and then the telescopic module 2 is opened, and the telescopic module 2 drives the cutting knife 5 to move downward through the mounting plate 3 and the transition plate 4, and at the same time, the mounting plate 3 drives the left and right flattening rollers 22 to move downward through all the swinging parts 21.

[0033] When the flattening roller 22 contacts the wire mesh during the downward movement of the flattening roller 22, the flattening roller 22 stops moving downward, and as the mounting plate 3 continues to move downward, the mounting plate 3 presses all the swinging members 21, and the swinging members 21 on the left and right sides swing in opposite directions (the first elastic member on the swinging member 21 twists and stores force), and the swinging members 21 drive the adjacent flattening rollers 22 to move, and the two flattening rollers 22 move in opposite directions, thereby squeezing and flattening the wire mesh, and the two flattening rollers 22 move from the middle of the wire mesh to both sides respectively to flatten the wire mesh, thereby ensuring the flatness of the wire mesh, and at the same time using the two flattening rollers 22 to fix the wire mesh, thereby ensuring the stability of the wire mesh during cutting, and reducing the deviation of the wire mesh when being cut, which affects the cutting accuracy.

[0034] During the downward movement of the mounting plate 3 (the parts on the rear sliding plate 8 are used as an example in this paragraph), the displacement sensor 311 is always in working condition and constantly detects the distance between the mounting plate 3 and the cutting table 6. When the flattening roller 22 contacts the wire mesh and the cutting knife 5 does not contact the wire mesh, the driving push rod 31 is opened, and its telescopic end drives the second rod 33 to move forward through the first rod 32 (the second rod 33 slides relative to the telescopic end of the elastic telescopic rod 35), and the second rod 33 drives the positioning member 34 to move forward. When the positioning member 34 contacts the edge of the wire mesh, the positioning member 34 slides along the edge of the wire mesh, and the edge of the wire mesh squeezes the positioning member 34, causing the positioning member 34 to move laterally (with the positioning member 34 moving laterally). Figure 5 As shown in the figure, taking the part moving to the right as an example), the positioning member 34 drives the second rod 33 to move to the right (the second rod 33 slides along the first rod 32), the second rod 33 drives the telescopic end of the elastic telescopic rod 35 to move, the telescopic end of the elastic telescopic rod 35 moves to the right and squeezes the hydraulic oil in the elastic telescopic rod 35, the hydraulic oil in the elastic telescopic rod 35 enters the fixed part of the first telescopic rod 36 through the first conduit 37, the telescopic end of the first telescopic rod 36 is retracted and drives the cutting knife 5 to move.

[0035] As the positioning member 34 moves forward and to the right, when the front side of the positioning member 34 moves to contact with the connection of the wire mesh, the positioning member 34 stops moving laterally, and the telescopic end of the first telescopic rod 36 stops moving. At this time, the position adjustment of the cutting knife 5 is completed, and the lower side of the cutting knife 5 is aligned with the connection of the wire mesh. When the positioning member 34 stops moving laterally, the telescopic end of the driving push rod 31 stops extending, and the positioning member 34 stops moving forward.

[0036] After the position of the cutting knife 5 is adjusted, as the mounting plate 3 moves downward, when the cutting knife 5 contacts the wire mesh, the cutting knife 5 starts to cut the wire mesh until the cutting knife 5 cuts the wire mesh. Then, the telescopic end of the telescopic module 2 is retracted and drives the cutting knife 5 to move upward. During this process, the mounting plate 3 drives the swing member 21 to move upward. The swing member 21 gradually rotates in the opposite direction under the action of the first elastic member thereon, and causes the two flattening rollers 22 to move toward each other. During the process of the two flattening rollers 22 moving toward each other, the cutting knife 5 gradually moves upward. When the cutting knife 5 loses contact with the wire mesh (the displacement sensor 311 detects the distance between the mounting plate 3 and the cutting table 6), the telescopic end of the driving push rod 31 is retracted.

[0037] The device actively drives the cutting knife 5 to move horizontally so that the position of the cutting knife 5 corresponds to the position of the connection of the wire mesh, thereby ensuring the accuracy of the wire mesh, making the edge of the cut wire mesh smooth and facilitating subsequent processing of the wire mesh.

[0038] After the position of the cutting knife 5 is adjusted, the distance between the cutting knife 5 and the upper limit block of the cutting table 6 changes. At this time, the moving distance of the cutting knife 5 is always smaller than the minor axis length of the diamond grid on the wire mesh. The resulting length of the wire mesh will change, but the change here does not affect the use.

[0039] During the process of retracting the telescopic end of the driving push rod 31, the positioning member 34 gradually loses contact with the wire mesh, the telescopic end of the elastic telescopic rod 35 is reset, and pushes the second rod 33 to reset, the hydraulic oil in the elastic telescopic rod 35 flows back, the telescopic end of the first telescopic rod 36 is reset, and drives the cutting knife 5 to reset, and when the telescopic end of the driving push rod 31 is fully retracted, all the parts on the sliding plate 8 are reset.

[0040] During the swinging process of the swinging member 21, when the swinging member 21 returns to its initial state, the swinging member 21 drives the flattening roller 22 to move upward, and the flattening roller 22 loses contact with the wire mesh until the telescopic end of the telescopic module 2 is fully retracted. All parts are reset, and the operator removes the cut wire mesh and pushes the side of the subsequent wire mesh until it contacts the upper limit block of the cutting table 6, repeats the above steps, and continues to cut the wire mesh.

[0041] In the above embodiment, the connection relationship between the mounting plate 3 and the transition plate 4 is fixed, while in the following embodiment, the two are slidably connected.

[0042] Since existing wire meshes are rolled up after production, the sides of the wire mesh will bend upward when the wire mesh is cut. The lengths of the projections of the bent wire mesh and the flattened wire mesh in the horizontal direction are different, which will affect the measured size of the wire mesh and the cutting operation. The above-mentioned embodiments are mainly for pre-treated wire mesh, while the following embodiments are for wire mesh with untreated edges. The untreated wire mesh edge is not at the connection, and the distance from the connection is uncertain. There are two uncertain factors affecting the position of the wire mesh, and thus affecting the relative position of the wire mesh connection and the cutting knife.

[0043] Example 2: Based on Example 1, Figure 2 and Figure 8-Figure 10 As shown, it also includes: a detection plate 41, which is slidably connected to the cutting table 6. The upper side of the cutting table 6 is provided with two symmetrically distributed sliding shells. The front and rear sides of the detection plate 41 are respectively located in the sliding shells on the adjacent cutting table 6 and slide. The detection plate 41 in this embodiment is used to replace the limit block of the cutting table 6 in the above embodiment; a mounting block 42, which is fixedly connected to the cutting table 6. The mounting block 42 is fixedly connected to the driving shell 43, and a second elastic member is fixedly connected between the detection plate 41 and the driving shell 43. The driving shell 43 is filled with hydraulic oil. The second elastic member on the detection plate 41 is a spring; the driving shell 43 is sealed and slidably connected to the push rod 44. The push rod 44 is used to push the hydraulic oil in the drive shell 43. The push rod 44 is fixedly connected to the detection plate 41. The drive shell 43 is fixedly connected and connected with a second conduit 45. The mounting plate 3 is fixedly connected with a second telescopic rod 46 connected with the second conduit 45. The second conduit 45 and the fixed part of the second telescopic rod 46 are filled with hydraulic oil. The connecting point between the second conduit 45 and the second telescopic rod 46 is located on the right side of the fixed part of the second telescopic rod 46 (that is, when oil is injected into the fixed part of the second telescopic rod 46, the telescopic end of the second telescopic rod 46 is retracted), the telescopic end of the second telescopic rod 46 is fixedly connected to the transition plate 4, and the transition plate 4 is slidably connected to the mounting plate 3.

[0044] Comparison Figure 2 , Figure 3 and Figure 8-Figure 11As shown, it also includes: a fixing ring 51, which is fixedly connected to the upper part of the driving shell 43, and the fixing ring 51 is located between the connecting part of the pushing rod 44 and the driving shell 43 and the second conduit 45; a blocking plate 52, which is slidably connected to the driving shell 43, and the blocking plate 52 is used to block the fixing ring 51, and a third elastic member is provided between the blocking plate 52 and the fixing ring 51, and the third elastic member of the blocking plate 52 is a tension spring, which is used to drive the blocking plate 52 to move downward, and a circular hole is provided on the fixing ring 51, and the third elastic member of the blocking plate 52 is located in the circular hole of the fixing ring 51; initially, the third elastic member of the blocking plate 52 is in a stretched state, that is, the blocking plate 52 does not block the fixing ring 51; the blocking plate 52 and the fixing ring 51 together form a one-way valve structure, that is, when the blocking plate 52 contacts with the fixing ring 51, the hydraulic oil can push the blocking plate 52 into the fixing ring 51. 2 is pushed open and flows from bottom to top, but cannot flow from top to bottom; an elastic pull rope 53 is fixedly connected between the mounting plate 3 and the blocking plate 52. Initially, the elastic pull rope 53 is in a stretched state, and the elastic pull rope 53 passes through the driving shell 43. The elastic pull rope 53 consists of an elastic part and a non-elastic part. The elastic part is located on the upper side of the non-elastic part, and the non-elastic part passes through the driving shell 43. The two are sealed and slidably connected. The mounting block 42 is rotatably connected to a guide wheel 54 through a bracket. The guide wheel 54 contacts the elastic part of the elastic pull rope 53. The guide wheel 54 is used to support and guide the elastic pull rope 53; the elastic coefficient of the elastic pull rope 53 is greater than the elastic coefficient of the third elastic member between the blocking plate 52 and the fixing ring 51, ensuring that the elastic pull rope 53 can pull the blocking plate 52 to move upward, thereby maintaining the state in which the blocking plate 52 does not block the fixing ring 51.

[0045] Workflow: When cutting the bent and unprocessed wire mesh, the operator places the wire mesh on the cutting table 6 so that the side of the wire mesh contacts the detection plate 41 (at this time, the side of the wire mesh is in an upwardly bent state), and then adjusts the position of the telescopic module 2 so that the horizontal distance between the cutting knife 5 and the detection plate 41 is consistent with the required length of the wire mesh, and then starts the cutting operation of the wire mesh (according to the cutting operation of Example 1).

[0046] During the downward movement of the mounting plate 3, the tension on the elastic pull rope 53 decreases, and the length of the elastic pull rope 53 gradually shortens. At the same time, the tension of the elastic pull rope 53 on the blocking plate 52 gradually decreases. After the elastic pull rope 53 no longer stores force, as the mounting plate 3 moves, the blocking plate 52 moves downward under the action of the third elastic member thereon, and the blocking plate 52 blocks the fixing ring 51, and then the elastic pull rope 53 gradually becomes relaxed.

[0047] After the flattening roller 22 contacts the wire mesh, as the mounting plate 3 moves downward, the two flattening rollers 22 move in opposite directions. The uneven portion in the middle of the wire mesh is driven to both sides by the movement of the flattening rollers 22 until the flattening rollers 22 contact the curved portion on the side of the wire mesh. The flattening rollers 22 flatten the curved portions on both sides of the wire mesh. When the curved portions on the side of the wire mesh are flattened, the side of the wire mesh moves downward and squeezes the detection plate 41. The detection plate 41 moves to the left. At this time, the distance between the detection plate 41 and the cutting knife 5 increases.

[0048] During the movement of the detection plate 41, the detection plate 41 drives the push rod 44 to move (the second elastic member on the detection plate 41 is compressed), the push rod 44 drives the hydraulic oil of the drive shell 43, the hydraulic oil in the drive shell 43 drives the blocking plate 52 to move, the blocking plate 52 releases the blocking of the fixing ring 51, the hydraulic oil passes through the blocking plate 52 and the fixing ring 51, and enters the fixing part of the second telescopic rod 46 through the second conduit 45, the telescopic end of the second telescopic rod 46 is retracted, the telescopic end of the second telescopic rod 46 drives the transition plate 4 to move, and the transition plate 4 drives the cutting plate 4 through the first telescopic rod 36 The cutting knife 5 moves synchronously (the telescopic end of the first telescopic rod 36 does not move). During this process, the displacement of the detection plate 41 is consistent with that of the cutting knife 5, so that the distance between the detection plate 41 and the cutting knife 5 in the horizontal direction is consistent with the initial distance, ensuring that it is consistent with the required length of the wire mesh. By flattening the edge of the wire mesh and using the edge of the wire mesh to squeeze the detection plate 41, the wire mesh is in a flat state and the transition plate 4 is moved a corresponding distance, reducing the impact of the wire mesh on its cutting accuracy due to the upward bending of the wire mesh, thereby ensuring the accuracy of the cutting length.

[0049] After the flattening roller 22 flattens the wire mesh, the detection plate 41 stops moving, and the cutting knife 5 stops moving. At this time, the connection between the cutting knife 5 and the wire mesh is not aligned.

[0050] After the flattening roller 22 flattens the wire mesh and the cutting knife 5 is not in contact with the wire mesh, when the displacement sensor 311 detects that the distance between the mounting plate 3 and the cutting table 6 reaches the specified value, the driving push rod 31 starts to work and adjusts the position of the cutting knife 5 according to the operation of Example 1, so that the connection between the cutting knife 5 and the wire mesh corresponds, thereby ensuring the cutting accuracy of the wire mesh.

[0051] After the cutting knife 5 completes cutting, the mounting plate 3 moves upward, and the mounting plate 3 drives the elastic pull rope 53 to move. The mounting plate 3 drives the cutting knife 5 to move upward through the transition plate 4, and the two flattening rollers 22 gradually move toward each other until the two flattening rollers 22 lose contact with the wire mesh, and the operator removes the cut wire mesh.

[0052] After the wire mesh is removed, the mounting plate 3 continues to move upward, and the mounting plate 3 pulls the elastic pull rope 53 to a taut state. After the elastic pull rope 53 is taut, the elastic pull rope 53 drives the blocking plate 52 to move, and the blocking plate 52 moves upward (the third elastic member of the blocking plate 52 is stretched), and the blocking plate 52 releases the blocking of the fixing ring 51. After the blocking plate 52 stops moving, the elastic pull rope 53 gradually accumulates force, and then the detection plate 41 moves to the right under the action of the third elastic member thereon, and the detection plate 41 drives the push rod 44 to move and draws back the hydraulic oil in the fixed part of the second telescopic rod 46, and the telescopic end of the second telescopic rod 46 drives the transition plate 4 to move and reset, and the push rod 44 drives the detection plate 41 to reset.

[0053] By delaying the resetting time of the detection plate 41, it is convenient for the operator to remove the cut wire mesh, and it is prevented that the detection plate 41 is immediately reset, which pushes the cut wire mesh to move and causes the wire mesh to stack.

[0054] After the mounting plate 3 is reset, the transition plate 4, the cutting knife 5 and the detection plate 41 are all reset, and the operator moves the subsequent side of the wire mesh to contact with the detection plate 41 and repeats the above steps to cut the wire mesh.

[0055] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
