Description

Technical Field

[0001] The present application relates to the field of industrial production automation technology, and in particular to an automatic feeding and cutting production line and production process for hoes. Background Art

[0002] The production process of a hoe can be roughly divided into several processes, such as cutting, forging, shaping and sharpening. Due to its simple process and low added value, the current semi-automatic production method adopts manual labor and equipment. At the same time, the source of raw materials is also relatively wide. Old rails, old plates, spring steel and other materials can be used for processing.

[0003] However, for large-scale production, these materials are no longer used because they require manual sorting, making it difficult to meet the production requirements of the assembly line. Currently, to achieve standardized production, the raw materials used in assembly lines are mostly customized plates (strip steel) directly from steel mills. The quality and dimensions of customized plates are guaranteed, which helps to reduce the difficulty of process adjustments and improve product consistency.

[0004] In terms of process automation, the current focus is on automating the connection between processes. This is because the current connection between processes mainly relies on manual handling, which adds unnecessary movements and requires workers to perform additional placement and picking actions. It is also not conducive to the subsequent use of robots in production.

[0005] There have been explorations into using jigs in conjunction with automated production, but each specification of product requires custom jigs, removal of old jigs, and installation of new jigs, which adds additional production costs. Summary of the Invention

DETAILED DESCRIPTION

[0027] The technical solution in this application is further described in detail below with reference to the accompanying drawings.

[0028] This application discloses a hoe automatic feeding and cutting production line. In some examples, please refer to Figure 1 and Figure 2 (The arrows in the figure indicate the movement path of the material), the hoe automatic loading and cutting production line disclosed in this application includes a wheeled transport unit 1, a heating and cutting module 2, a clamping transporter 3, a clamping and shifting turntable 4 and a clamping transporter 5.

[0029] The wheeled transport unit 1 is set along the moving direction of the strip material. Its function is to ensure that the strip material moves along the set direction. The function of the heating and cutting module 2 is to cut the strip material. Of course, in this process, it is also necessary to select whether heating is required based on parameters such as the material, thickness and width of the strip material.

[0030] It should be understood that manganese steel has a high hardness, but if it is directly cut by cold cutting, it will cause defects such as cracks at the cut. These defects will directly affect the quality of the final product, such as localized lack of strength leading to breakage during use. When the material is thick or wide, the above problems are also prone to occur. Therefore, it is necessary for the staff to determine whether to heat the strip material based on parameters such as material, thickness and width.

[0031] The number of wheeled transport units 1 is one or more. When the number of wheeled transport units 1 is one, the heating and cutting module 2 is located inside the wheeled transport unit 1; when the number of wheeled transport units 1 is more than one, the heating and cutting module 2 is located between two adjacent wheeled transport units 1.

[0032] The number of heating and cutting modules 2 can be one or more. Multiple heating and cutting modules 2 can realize multiple heating and cutting of strip materials, with the aim of avoiding local defects as much as possible. This method is mostly used in processing thicker plates.

[0033] See also Figure 4 The heating and cutting module 2 includes an open induction heating unit 21 and a cutter 22. In the moving direction of the material, the open induction heating unit 21 is located in front of the cutter 22. The function of the open induction heating unit 21 is to locally heat the strip material, and the function of the cutter 22 is to cut the strip material.

[0034] exist Figure 4 As can be seen in the figure, the coil in the open induction heating unit 21 is arranged vertically so that strip materials of different widths can be heated when passing through the coil. The coil extends from the top of the bracket and is connected to a power source (not shown).

[0035] In some possible implementations, the cutter 22 includes a linear unit driven by a hydraulic cylinder and a cutter, the cutter including a fixed knife and a movable knife, and the linear unit driven by the hydraulic cylinder is responsible for driving the movable knife to move horizontally to cut the strip material from both sides.

[0036] In some other possible implementations, the number of linear units driven by hydraulic cylinders is increased to two, and the two cutters are respectively mounted on the corresponding linear units driven by hydraulic cylinders, such as Figure 5 shown.

[0037] The first end of the clamping conveyor 3 is located at the output end of the last wheeled transport unit 1, and the second end is a free end. The function of the clamping conveyor 3 is to transport strip materials of standard length and intermediate materials produced in various processing steps.

[0038] The clamping and shifting turntable 4 is located between the clamping conveyor 3 and the output end of the last wheeled transport unit 1 , and its function is to transfer the strip materials of standard length to the clamping conveyor 3 .

[0039] The gripping transporters 5 are arranged at intervals along the gripping conveyor 3 , and the gripping transporters 5 are used to transfer materials at the gripping conveyor 3 to a processing location and transfer materials at the processing location back to the gripping conveyor 3 .

[0040] The materials at the clamping conveyor 3 include strip materials of standard length and intermediate materials produced in various processing steps. The materials at the processing position refer to the intermediate materials produced in various processing steps.

[0041] A group (two) of clamping transporters 5 are placed at each transfer position of the clamping transporter 3, one is responsible for transferring the material at the clamping transporter 3 to the processing position, and the other is responsible for transferring the material at the processing position back to the clamping transporter 3.

[0042] Considering a single processing step, the staff is located at the processing equipment and takes the standard length of strip material or intermediate material from the clamping transporter 5 on one side. After the processing at this step is completed, it is placed on the clamping transporter 5 on the other side, or on another clamping transporter 5 on the same side.

[0043] For the staff, there is no need to carry out material handling. Each picking and placing is done at a fixed workstation. If automatic robotic arms are used to replace manual labor in the future, the automatic robotic arms can pick up and place at a fixed position and can be directly replaced.

[0044] For some examples, see Figure 3 The wheeled transport unit 1 includes an outer shell 11, two sets of clamping rollers 12 and two sets of pressing rollers 13. The clamping rollers 12 and the pressing rollers 13 are both rotatably connected to the outer shell 11. There is a material channel in the outer shell 11. The two sets of clamping rollers 12 and the two sets of pressing rollers 13 are symmetrically arranged on both sides of the material channel in the outer shell 11.

[0045] Generally speaking, the pressure roller 13 is driven by a motor (not shown) mounted on the housing 11 , and the clamping roller 12 is generally driven by the motor.

[0046] The material channel is used to feed the strip material. The clamping roller 12 contacts the strip material, mainly playing a positioning role, and the pressure roller 13 also contacts the strip material, mainly playing a pushing role. When the number of clamping rollers 12 and pressure rollers 13 is large, the strip material can also be straightened to a certain extent, which helps to accurately discharge the strip material.

[0047] See also Figure 1 and Figure 6The clamping conveyor 3 includes a conveying platform 31, a first conveying belt 32, a second conveying belt 33, a third conveying belt 34 and a width adjuster 35. The first conveying belt 32, the second conveying belt 33 and the third conveying belt 34 are all fixedly installed on the conveying platform 31. The first conveying belt 32 is installed horizontally, and the second conveying belt 33 and the third conveying belt 34 are installed vertically.

[0048] The second conveyor belt 33 and the third conveyor belt 34 are perpendicular to the first conveyor belt 32 and there is a gap between the second conveyor belt 33 and the third conveyor belt 34. The gap is used for strip materials of standard length and intermediate materials produced in various processing steps.

[0049] Specifically, the materials (strip materials of standard length and intermediate materials produced in various processing steps) are first transferred to the gap, and then the first conveyor belt 32, the second conveyor belt 33, and the third conveyor belt 34 are started at the same time to drive the materials to move. The first conveyor belt 32 is responsible for providing forward power during movement, and the second conveyor belt 33 and the third conveyor belt 34 fix the materials in a moving state so that the posture of the materials in a moving state can remain unchanged.

[0050] The function of the width adjuster 35 is to adjust the gap width. It should be understood that the thickness of the material will change after undergoing different processing steps. At this time, gaps of different widths are required for clamping. The solution used in this application is to use a width adjuster 35 to adjust the gap width between the second conveyor belt 33 and the third conveyor belt 34.

[0051] There are multiple width adjusters 35 and they are arranged at intervals along the gap between the second conveyor belt 33 and the third conveyor belt 34, so that the gap at different positions can be adjusted separately, that is, the gap between the second conveyor belt 33 and the third conveyor belt 34 can be divided into multiple sections, and the width of each section of the gap is different.

[0052] In some possible implementations, the width adjuster 35 is combined with the support roller of the conveyor belt, such as Figure 6 As shown, the support roller is installed on a telescopic body (telescopic cylinder) with a length adjustment function, and a second conveyor belt 33 and a third conveyor belt 34 use two sets of width adjusters 35, which can ensure that the conveyor belts are in a taut state while adjusting the gap width.

[0053] In addition, when the products produced change, the gap widths at various locations can also be dynamically adjusted. This method does not require targeted fixture production, nor does it involve the disassembly, assembly, and replacement of fixtures, and can meet the production needs of flexible production.

[0054] For some examples, see Figure 7 and Figure 8The clamping and shifting turntable 4 includes an electric turntable 41, a clamping body 42, an adjustment spring 43 and a position adjustment ring 44. A plurality of clamping positions are provided on the side of the electric turntable 41. Two clamping bodies 42 are placed at each clamping position. The clamping bodies 42 are located in the clamping positions and are slidably connected to the electric turntable 41.

[0055] The ends of the adjustment spring 43 respectively abut the electric turntable 41 and the clamping body 42, pushing the clamping body 42 out of the clamping position. One adjustment surface of the clamping body 42 abuts the position adjustment ring 44. When the electric turntable 41 rotates, the position adjustment ring 44 is stationary, and the adjustment surface of the clamping body 42 slides on the adjustment surface of the position adjustment ring 44.

[0056] The adjustment surface of the position adjustment ring 44 is a curved surface, and different positions have different distances from the center position of the position adjustment ring 44. Through the adjustment surface of the position adjustment ring 44, the distance between the clamping body 42 and the center position of the position adjustment ring 44 can be changed, that is, during the rotation of the electric turntable 41, the clamping body 42 in the clamping position slides according to the set requirements.

[0057] Each clamping position contains two clamping bodies 42. The surfaces of the clamping bodies 42 that slide into the inner side of the clamping position are inclined surfaces. Adjacent surfaces of the two clamping bodies 42 within the same clamping position are arranged parallel to each other. When the size of the adjustment surface of the position adjustment ring 44 changes, the width of the gap between the two clamping bodies 42 within the same clamping position also changes, allowing the clamping of strips of varying thicknesses.

[0058] exist Figure 8 It can be seen from the figure that when the clamping body 42 is located at the top and bottom, the width of the gap in the middle increases, and when the clamping body 42 is located at the left side and the right side, the width of the gap in the middle decreases.

[0059] In some possible implementations, the electric turntable 41 is composed of two turntables spliced ​​together. This structure allows a slide groove to be directly processed on the inner side surface of the turntable for use by the clamping body 42.

[0060] In some possible implementations, there is a position adjustment ring 44 on both sides of the electric turntable 41, the purpose of which is to simultaneously apply thrust to both sides of the clamping body 42 to ensure stability during the process of clamping the strip material.

[0061] For some examples, see Figure 9 The clamping transporter 5 includes a linear rail 51, a longitudinal moving platform 52 and a clamper 53. The linear rail 51 is located above the clamping transporter 3 and is generally fixed using a bracket. The working direction of the linear rail 51 is perpendicular to the working direction of the clamping transporter 3 and the linear rail 51 is horizontally arranged.

[0062] The longitudinal movable platform 52 is fixed on the linear rail 51 and is responsible for height adjustment. The clamper 53 is installed on the longitudinal movable platform 52 and is responsible for clamping strip materials of standard length and intermediate materials produced in various processing steps.

[0063] In simple terms, the linear rail 51 is responsible for horizontal movement, the longitudinal moving platform 52 is responsible for vertical movement, and the clamper 53 first descends above the clamping conveyor 3, clamps the standard length of strip materials and the intermediate materials produced by each processing step, then rises and is transferred to the processing position.

[0064] After the processing is completed, another clamping transporter 5 is used to send it back to the clamping transporter 3, and the clamping transporter 3 transports it to the next processing step.

[0065] In some possible implementations, the clamp 53 includes a clamp body 531 and a clamp 532 detachably connected to the clamp body 531. The purpose of using a detachable connection for the clamp 532 is to facilitate replacement. The clamp 532 is composed of two plates. The clamping surfaces of the plates need to be adjusted according to the shape of the material to achieve surface contact and increase the contact pressure at the clamping point.

[0066] The present application also discloses a hoe automatic feeding and cutting production process, comprising the following steps: The wheeled transport unit 1 is used to transport the strip material and the heated cutting module 2 is used to cut the material into standard materials of equal length; Use the clamping and shifting turntable 4 to transfer the standard material to the clamping conveyor 3 and the clamping conveyor 3 transfers the standard material to the processing position; The standard material is transferred to the processing equipment using the gripping transporter 5 for processing, and then transferred back to the gripping transporter 3 and moved to the next processing position, and so on, until all the processing steps are completed.

[0067] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
