Description

Technical Field

[0001] This application relates to the field of air duct processing equipment technology, and in particular to a feeding device for a shearing machine used in air ducts. Background Technology

[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. With the help of a moving upper blade and a fixed lower blade, and by using a reasonable blade gap, shearing force is applied to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions. In the production process of bus ventilation ducts, shearing machines are often used to shear the duct sheets.

[0003] In the existing technology, when shearing sheet metal, workers need to draw positioning lines on the surface of the sheet metal according to the position to be processed. Then, the workers manually push the sheet metal into the shearing machine. When the blade is aligned with the drawn positioning line, the shearing machine is started to perform the shearing operation. After one sheet metal is processed, the workers need to measure and mark the positioning line position of the next sheet metal and repeat the above pushing and shearing steps.

[0004] Therefore, in the conventional process of cutting air duct plates, workers need to frequently mark lines on each plate, which prolongs the overall cutting time of the air duct plates and reduces the cutting efficiency, resulting in significant shortcomings. Utility Model Content

[0005] To improve the shearing efficiency of sheet metal, this application provides a feeding device for a shearing machine used in air ducts.

[0006] The shearing machine feeding device for air ducts provided in this application adopts the following technical solution: A feeding device for a shearing machine in an air duct includes a worktable, a frame on the worktable, a shearing device on the frame, a support frame on the side of the worktable near the outlet of the shearing device, a receiving shell inside the support frame, a spacer plate and a driving assembly inside the receiving shell, the driving assembly driving the spacer plate to slide vertically inside the receiving shell, and when the spacer plate abuts against the inner wall of the receiving shell near the worktable, the spacer plate abuts against the surface of the worktable.

[0007] By adopting the above technical solution, the sheet material is first placed on the worktable. Then, the drive component drives the spacer plate to move downwards along the receiving shell until the spacer plate abuts against the worktable. Subsequently, the worker pushes the sheet material to slide along the working length direction. When the end of the sheet material abuts against the spacer plate, the position of the sheet material to be processed is located below the shearing device. The worker starts the shearing device to process it. After processing, the drive component drives the spacer plate to move upwards along the receiving shell and retract into the receiving shell. At this time, the worker puts the sheared sheet material from the exit of the worktable and puts in the next sheet material to repeat the above actions. By driving the spacer plate to limit the movement of the sheet material, the spacer plate is sheared at a fixed distance. There is no need for the worker to draw lines before shearing each sheet material, which shortens the overall shearing time and improves the shearing efficiency.

[0008] Optionally, the inner sidewalls of the receiving shell are provided with multiple guide grooves, which are distributed along the length of the receiving shell, and guide blocks that slide with the guide grooves are provided on opposite sides of the spacer plate.

[0009] By adopting the above technical solution, the sliding cooperation of the guide groove and the guide block restricts the sliding direction of the spacer plate, reduces the possibility of changes in the spacer length due to the tilt of the spacer plate, and thus ensures the accuracy of the plate shearing position.

[0010] Optionally, the drive assembly includes a take-up shaft rotatably connected to the top of the housing, with connecting ropes wound on the take-up shaft corresponding to each of the guide blocks. The free ends of the connecting ropes are disposed on the spacer plate. Each guide groove is provided with a retaining spring. The elastic force of the retaining spring drives the spacer plate to abut against the worktable. The housing is provided with a drive motor that drives the take-up shaft to rotate.

[0011] By adopting the above technical solution, during shearing, the drive motor is started to rotate the take-up shaft in the opposite direction, and the take-up shaft unwinds the connecting rope to make it loose. Under the action of the elastic force of the clamping spring and the gravity of the spacer plate, the spacer plate moves downward and abuts against the surface of the worktable. After shearing is completed, the drive motor rotates the take-up shaft in the forward direction, and the take-up shaft winds up the connecting rope. The connecting rope lifts the spacer plate upward until it is stored in the receiving shell. This avoids the spacer plate from obstructing the movement of the sheet material.

[0012] Optionally, the support frame has a sliding groove along the length of the workbench, an adjusting screw is rotatably connected inside the sliding groove, a sliding block is provided on the outer surface of the receiving shell that is threadedly engaged with the adjusting screw, the sliding block is slidably disposed inside the sliding groove, and a handwheel is coaxially provided at the end of the adjusting screw extending out of the support frame.

[0013] By adopting the above technical solution, when cutting boards of different lengths, the worker turns the handwheel to drive the adjusting screw to rotate. Under the limit of the sliding groove and the sliding block, the adjusting screw drives the sliding block to move along the sliding groove. The sliding block drives the receiving shell to move, thereby realizing the change of the limiting position of the fixed plate to adapt to the cutting of boards of different lengths.

[0014] Optionally, the support frame is provided with scale markings along its length.

[0015] By adopting the above technical solution, during the adjustment of the distance plate position, the scale markings help workers observe the position of the distance plate, thus facilitating precise adjustment by the workers.

[0016] Optionally, the workbench is provided with limiting plates on both opposite sides along the width direction, and the limiting plates abut against the opposite outer end faces of the plate.

[0017] By adopting the above technical solution, during the conveying process of the sheet metal, the limiting plates on both sides restrict the conveying direction of the sheet metal, reducing the possibility of shearing deviation caused by the overall skewing of the sheet metal, thereby improving the shearing accuracy of the shearing machine.

[0018] Optionally, the end of the worktable away from the support frame is provided with an electric push rod corresponding to each of the two limiting plates. The output shaft of the electric push rod is set on the corresponding limiting plate. The frame is provided with guide columns along the width direction of the worktable, and both limiting plates are slidably connected to the guide columns.

[0019] By adopting the above technical solution, when cutting plates of different widths, the worker simultaneously starts two electric push rods. Under the guidance of the guide column, the electric push rods drive the two limiting plates to move away from or closer to each other, so that the distance between the two limiting plates is adapted to the width of the plate, ensuring the limiting effect of the limiting plates on the plate during transmission.

[0020] Optionally, the two limiting plates have grooves on their opposite end faces. Multiple conveying rollers are rotatably connected to the grooves along their length. The multiple conveying rollers abut against the outer surface of the plate. A conveying assembly is provided on the limiting plate. The conveying assembly includes synchronous pulleys coaxially connected to the conveying rollers. Multiple synchronous pulleys are rotatably connected to the outer surface of the limiting plate. A synchronous belt is fitted onto the outer surface of two adjacent synchronous pulleys. A conveying motor that drives one of the synchronous pulleys to rotate is provided on the limiting plate.

[0021] By adopting the above technical solution, after the worker places the board on the workbench, the electric push rod pushes the conveyor roller on the limit plate to abut against the outer end face of the board. Then, the conveyor motor starts and drives one of the conveyor rollers to rotate. Under the transmission action of the synchronous pulley and synchronous belt, multiple conveyor rollers rotate synchronously. When the conveyor rollers rotate, they drive the board towards the shearing device, thus realizing automatic feeding of the board without the need for manual pushing of the board, which further improves the shearing efficiency of the shearing machine.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This application, by setting up a drive assembly and a spacer plate, first places the sheet material on the worktable, then the drive assembly drives the spacer plate to move downwards along the receiving shell until the spacer plate abuts against the worktable. Then, the worker pushes the sheet material to slide along the working length direction. When the end of the sheet material abuts against the spacer plate, the position of the sheet material to be processed is located below the shearing device. The worker starts the shearing device to process it. After processing, the drive assembly drives the spacer plate to move upwards along the receiving shell and retract into the receiving shell. At this time, the worker puts the sheared sheet material from the exit of the worktable and puts in the next sheet material to repeat the above actions. By driving the spacer plate to limit the movement of the sheet material through the drive assembly, the spacer plate is sheared at a fixed distance. There is no need for the worker to draw lines before shearing each sheet material, which shortens the overall shearing time and improves the shearing efficiency. 2. This application improves the shearing accuracy of the shearing machine by setting a limiting plate, which restricts the conveying direction of the sheet material and reduces the possibility of shearing deviation caused by the overall skewing of the sheet material. 3. This application sets up a conveying component. The conveying motor starts and drives one of the conveying rollers to rotate. Under the transmission action of the synchronous pulley and synchronous belt, multiple conveying rollers rotate synchronously. When the conveying rollers rotate, they drive the plate to move towards the shearing device, thus realizing automatic feeding of the plate without the need for manual pushing of the plate, which further improves the shearing efficiency of the shearing machine.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a feeding device for a shearing machine used in air ducts.

[0030] Reference Figure 1 and Figure 2 A shearing machine feeding device for air ducts includes a workbench 1. A frame 2 and a support frame 3 are installed sequentially along the length of the workbench 1. Both the frame 2 and the support frame 3 are gantry-shaped and erected in the width direction of the workbench 1. A shearing device 01 is installed on the frame 2. The specific composition and principle of the shearing device 01 of the shearing machine are all existing technologies and will not be described in detail in this embodiment. When the sheet metal moves to the shearing device 01, the shearing device 01 performs shearing processing on the sheet metal.

[0031] Reference Figure 1 and Figure 2 Two electric push rods 4 are installed on the end face of the worktable 1 near the inlet of the shearing device 01. The two electric push rods 4 are respectively set on opposite sides of the worktable 1 along the width direction. The output end of each electric push rod 4 is fixedly connected to a limit plate 41. The limit plate 41 is parallel to the length direction of the worktable 1 and slides along the width direction of the worktable 1. A guide column 21 is fixedly installed on the frame 2. The end of the limit plate 41 away from the electric push rod 4 is slidably sleeved on the outer surface of the guide column 21.

[0032] Reference Figure 1 and Figure 2The two limiting plates 41 each have a groove 411 on their opposite end faces. The groove 411 is parallel to the length direction of the worktable 1. Multiple conveying rollers 412 are rotatably connected in each groove 411 along the length direction. After the board is placed on the worktable 1, the worker simultaneously starts two electric push rods 4. Under the guidance of the guide column 21, the electric push rods 4 drive the two limiting plates 41 to move closer to each other. When multiple conveying rollers 412 are all in contact with the outer surface of the board, the electric push rods 4 are turned off. At this time, the two limiting plates 41 and the conveying rollers 412 form a limit on the conveying direction of the board, reducing the possibility of the board being skewed in the width direction of the worktable 1 during the feeding process, thereby ensuring the cutting accuracy of the shearing machine.

[0033] Reference Figure 1 and Figure 2 The limiting plate 41 is provided with a conveying component 5, which includes a synchronous wheel 51 coaxially connected to the conveying roller 412. Multiple synchronous wheels 51 are rotatably connected to the upper surface of the limiting plate 41 away from the worktable 1. The outer surfaces of two adjacent synchronous wheels 51 are jointly fitted with a synchronous belt 52. A conveying motor 53 is fixedly installed on the limiting plate 41, and the output shaft of the conveying motor 53 is coaxially fixedly connected to one of the synchronous wheels 51.

[0034] After the electric push rod 4 drives the conveyor roller 412 to abut against the end face of the plate, the worker starts the conveyor motor 53. The conveyor motor 53 drives one of the conveyor rollers 412 to rotate. Under the transmission action of the synchronous pulley 51 and the synchronous belt 52, multiple conveyor rollers 412 rotate synchronously. When the conveyor roller 412 rotates, it drives the plate to move towards the shearing device 01. In this way, the automatic feeding of the plate is realized, and there is no need for manual pushing of the plate, thereby improving the shearing efficiency of the shearing machine.

[0035] Reference Figure 3 and Figure 4 The support frame 3 has a housing 6 embedded inside. The housing 6 is square in shape, and multiple guide grooves 61 are opened along the length direction on the opposite inner sidewalls. Each guide groove 61 is vertically arranged and a guide block 71 is slidably connected inside. A spacer plate 7 is connected between the multiple guide blocks 71. A drive assembly 8 is provided inside the housing 6 to drive the spacer plate 7 to move inside the housing 6. When the drive assembly 8 drives the spacer plate 7 to abut against the surface of the worktable 1, the spacer plate 7 restricts the movement of the plate in the length direction of the worktable 1.

[0036] Reference Figure 3 and Figure 4Specifically, the drive assembly 8 includes a take-up shaft 81 rotatably connected to the top of the housing 6. A drive motor 82 is fixedly mounted on the top of the housing 6. The output shaft of the drive motor 82 is coaxially fixedly connected to the take-up shaft 81. The top of the support frame 3 has a clearance groove 31 along the width direction of the worktable 1 to avoid the take-up shaft 81 and the drive motor 82. A connecting rope 83 corresponding to a plurality of guide blocks 71 is wound on the take-up shaft 81. The free end of the connecting rope 83 extends into the housing 6 and is bolted to the upper surface of the spacer plate 7. Each guide groove 61 is provided with a retaining spring 84. One end of the retaining spring 84 is fixedly connected to the inner side wall of the guide groove 61 near the take-up shaft 81, and the other end is fixedly connected to the guide block 71. The direction of the elastic force of the retaining spring 84 on the spacer plate 7 is the same as the direction of gravity.

[0037] Before the conveying assembly 5 is started, the drive motor 82 is started to rotate the take-up shaft 81 in the reverse direction. The take-up shaft 81 unwinds the connecting rope 83, making it slack. Under the elastic force of the retaining spring 84 and the gravity of the spacer plate 7, the spacer plate 7 moves downward along the guide groove 61 and finally abuts against the surface of the worktable 1. When the conveying assembly 5 conveys the board to the position where it abuts against the spacer plate 7, the position of the board to be processed is located below the shearing device 01. The worker starts the shearing device 01 to process it. After processing is completed, the drive motor 82 rotates the take-up shaft 81 in the forward direction. The take-up shaft 81 winds up the connecting rope 83. The tension spring 84 pulls the spacer plate 7 upward until it is housed inside the receiving shell 6. At this point, the spacer plate 7 stops blocking the material. The conveying assembly 5 continues to convey the material until it leaves the shearing device 01. The worker places the sheared material from the exit of the workbench 1 and repeats the above actions. The drive assembly 8 drives the spacer plate 7 to limit the movement of the material, thus achieving fixed-distance shearing of the material. There is no need for the worker to draw lines before shearing each material, which shortens the overall shearing time and improves the shearing efficiency.

[0038] Reference Figure 3 and Figure 4 The inner sidewall of the support frame 3 is provided with a sliding groove 32 along the length of the workbench 1. The top surface of the support frame 3 is provided with a scale mark 10 that matches the length of the sliding groove 32. An adjusting screw 9 is rotatably connected inside one of the sliding grooves 32. A sliding block 62 that slides with the sliding groove 32 is fixedly connected to the outer surface of the housing 6. One of the sliding blocks 62 is threaded to the outer surface of the adjusting screw 9. The end of the adjusting screw 9 extends out of the outer surface of the support frame 3 and is coaxially fixedly connected to a handwheel 91.

[0039] When the length of the sheet material to be processed changes, the worker turns the handwheel 91 to drive the adjusting screw 9 to rotate. Under the limit of the sliding groove 32 and the sliding block 62, the adjusting screw 9 drives the sliding block 62 to move along the sliding groove 32. The sliding block 62 drives the receiving shell 6 to move, thereby changing the limiting position of the spacer plate 7 to adapt to the cutting of sheet materials of different lengths. When the worker observes through the scale mark 10 that the receiving shell 6 has reached the specified length, he stops turning the handwheel 91.

[0040] The implementation principle of a shearing machine feeding device for air ducts in this application embodiment is as follows: Before the conveying component 5 is started, the drive motor 82 is started to rotate the take-up shaft 81 in the reverse direction. The take-up shaft 81 unwinds the connecting rope 83 to loosen it. Under the elastic force of the clamping spring 84 and the gravity of the spacer plate 7, the spacer plate 7 moves downward along the guide groove 61 and finally abuts against the surface of the worktable 1. When the conveying component 5 conveys the plate to abut against the spacer plate 7, the position of the plate to be processed is located below the shearing device 01. The worker starts the shearing device 01 to process the plate. After processing is completed, the drive motor 82 rotates the take-up shaft 81 in the forward direction to rewind the plate. Shaft 81 winds up connecting rope 83. The lifting force of connecting rope 83 overcomes the elastic force of the clamping spring 84, pulling the spacer plate 7 upward until it is stored inside the receiving shell 6. At this time, the obstruction effect of the spacer plate 7 on the plate disappears. The conveying component 5 continues to convey the plate until the plate leaves the shearing device 01. The worker puts the sheared plate from the exit of the workbench 1 and puts the next plate into it, repeating the above actions. The drive component 8 drives the spacer plate 7 to limit the movement of the plate, thereby realizing the fixed-distance shearing of the plate. There is no need for the worker to draw lines before shearing each plate, which shortens the overall shearing time and improves the shearing efficiency.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
