Description

Technical Field

[0001] The present application relates to the field of industrial production technology, and in particular to a hoe production line and production process. Background Art

[0002] Hoes are a commonly used agricultural tool, widely used in small-scale agriculture and overseas markets. Current production processes often use rail steel, which is manganese steel and has advantages in hardness and wear resistance.

[0003] The general processing process consists of three stages: cutting (shortening the rail steel to the appropriate length), forging and shaping. In this processing process, one advantage of rail steel is that it has a certain thickness, which can be used to process the connection hole at the tail.

[0004] However, with the rise in labor costs and environmental protection requirements, the above processing process can no longer meet production requirements. On the one hand, this is because forging requires multiple heatings, which consumes a lot of electricity; on the other hand, due to the increase in labor costs, the product price does not have sufficient advantages.

DETAILED DESCRIPTION

[0063] In order to more clearly understand the technical solution of this application, first compare the redesigned hoe structure with the existing hoe structure. Figure 1The existing hoe structure is an integral forging molding. The hoe structure redesigned in this application adopts a structure in which the panel and the ring are processed separately and then welded together. Figure 2 shown.

[0064] The advantage of separate processing followed by welding is that both the panel and the collar can be processed automatically.

[0065] The technical solution in this application is further described in detail below with reference to the accompanying drawings.

[0066] The present application discloses a hoe production line. In some examples, the hoe production line disclosed in the present application includes a transport platform 11, a transport belt 12, a jig 13, a lifting platform 14, a forging and cutting die set 21, a grabbing robot 22, a forging and pressing die set 23 and a welding die set 24.

[0067] The transport platform 11, transport belt 12, jig 13 and forging die set 21 are responsible for making the base material;

[0068] The lifting platform 14, the grabbing manipulator 22 and the forging die set 23 are responsible for shaping the substrate;

[0069] The welding module 24 is responsible for welding the base material and the ferrule together.

[0070] See also Figure 3 A conveyor belt 12 is provided on the transport platform 11. The function of the conveyor belt 12 is to drive the fixture 13 to move on the transport platform 11. Figure 3 The arrow in the figure indicates the moving direction of the jig. Specifically, there are two conveyor belts 12 installed on the inner side of the transport platform 11 , and the jig 13 is placed on the conveyor belts 12 .

[0071] Both sides of the jig 13 are pressed on the conveyor belt 12. When the conveyor belt 12 rotates, the jig 13 moves forward and stops moving when the jig 13 moves above the lifting platform 14.

[0072] There are multiple lifting platforms 14, all of which are located below the transport platform 11 and spaced apart along the transport platform 11. The function of the lifting platforms 14 is to separate the jig 13 from the conveyor belt 12 because the pressure generated during the forging process is greater than the load limit of the transport platform 11 and the conveyor belt 12.

[0073] The pressure generated during the forging process is borne by the lifting platform 14.

[0074] The forging and cutting die set 21 is located on one side of the transport platform 11. The function of the forging and cutting die set 21 is to perform circular edge forging on the plate placed on the jig 13. At this time, a base material and waste are obtained. The obtained base material falls onto the lifting platform 14, and the obtained waste is located on the jig 13.

[0075] Regarding the above, let's first introduce the plate. The plate is made of rail steel. The process is to directly forge the rail steel into sections. The thickness of the plate is greater than the thickness of the finished product. This is partly due to oxidation loss and partly to reserve processing capacity for subsequent processing.

[0076] Of course, during the forging process here, the shape of the plate can also be constrained by a mold. At this time, the staff only needs to observe the process, place the heated material in the mold, and then take the forged plate out of the mold.

[0077] When a certain degree of automation is required, the process can be replaced by a robot.

[0078] The plate is placed on the fixture 13. The specific structure of the fixture 13 is as follows. Figure 4 The fixture 13 includes a fixture body 131, a placement bin 132 and a step 133. The placement bin 132 is located on the fixture body 131. The top and bottom surfaces of the placement bin 132 are both open ends.

[0079] Specifically, the placement bin 13 is connected to the top surface of the treatment body 131 and the bottom surface of the treatment body 131 , and a step 133 is further provided on the inner wall of the placement bin 132 .

[0080] When the plate is placed inside the placement bin 132 , its edge is pressed against the step 133 , and at this time, the top surface and the bottom surface of the plate are in direct contact.

[0081] When the plate stops moving, it is located just above the lifting platform 14. The function of the lifting platform 14 is to lift the plate, and then cooperate with the forging and cutting die set 21 to forge and cut the plate. Forging and cutting is to cut the plate into a suitable shape. At this time, a certain amount of waste will be generated, and the waste can be recycled to make new raw materials.

[0082] See also Figure 3 and Figure 5 The lifting platform 14 includes a base 141, a guide channel 142, a lifting body 143 and a sliding body 144. The guide channel 142 is set on the base 141. The lifting body 143 is slidably connected to the guide channel 142 and can perform linear reciprocating motion along the guide channel 142.

[0083] Sliding body 144 is slidably connected to base 141 and can extend into guide channel 142, pushing elevating body 143 to slide along guide channel 142. Specifically, the bottom surface of elevating body 143 is an inclined surface, and the top surface of sliding body 144 is also an inclined surface. When sliding body 144 moves horizontally, it can push elevating body 143 to move vertically.

[0084] See also Figure 6The forging die set 21 mainly consists of a main body 211, a hydraulic cylinder 212, and a forging cutter 213. The hydraulic cylinder 212 is mounted on the main body 211, and the forging cutter 213 is mounted on the hydraulic cylinder 212. The hydraulic cylinder 212 drives the forging cutter 213 to move in the vertical direction, forging and cutting the plate into a circular edge to obtain base material and scrap.

[0085] At the same time, in order to ensure the forging effect, a step can be set on the working surface of the lifting body 143 to ensure that the connection between the base material and the waste material can be cut off. Figure 7 shown.

[0086] The grabbing robot 22 transfers the substrate to the forging die 23, and the forging die 23 shapes the substrate. The shaping here is divided into two parts: one is to adjust the thickness of the substrate to make the head thin and the tail thick, and the other is to adjust the edge of the substrate to remove the sharp corners of the edge of the substrate.

[0087] The structure of the forging die set 23 is the same as that of the forging die set 21 , except that the forging die set 23 requires a die, which reshapes the substrate during repeated contact with the substrate.

[0088] The function of the welding module 24 is to weld the shaped base material and the sleeve together. The sleeve can be directly processed by pipe cutting. During welding, the shaped base material is placed on the workbench of the welding module 24, and then the sleeve is placed in the positioning area on the welding module 24.

[0089] Welding module 24 then drives the collar or substrate to rotate at high speed and compresses the collar and substrate. This process generates a large amount of heat, welding the substrate and collar together. In other words, in this application, welding module 24 utilizes friction welding. This section is prior art and will not be further elaborated here.

[0090] See also Figure 9 The welding module 24 consists of three parts: a rotating table 241, a workbench 242 and a presser 243. The substrate is placed in the slot on the rotating table 241, and the ring is placed in the groove 244 on the presser 243. The presser 243 pushes the ring to press on the substrate, and the rotating table 241 drives the substrate to rotate at high speed to weld the ring and the substrate together.

[0091] From the above introduction, it can be seen that on the moving path of the substrate, the transport platform 11, the forging die 23 and the welding die 24 are arranged in sequence. The plate passes through the forging die 23 to obtain the substrate, and the substrate passes through the welding module 24 to obtain the finished product.

[0092] The substrate can be transferred to and removed from the welding module 24 manually or by a robot.

[0093] In the above process, the manual steps involved are only the placement and removal of materials. The manual operation steps are few and the difficulty is low, and can even be replaced by automated equipment.

[0094] For some examples, see Figure 11 The grabbing robot 22 includes a robot arm 221, a grabbing plate 222, a grabbing bin 223, a telescopic member 224 and a wedge-shaped member 225, and the grabbing plate 222 is installed on the robot arm 221. A grabbing bin 223 is provided on the grabbing plate 222, and the function of the grabbing bin 223 is to cover the substrate.

[0095] A telescopic member 224 is further provided on the grabbing plate 222 , and a working end of the telescopic member 224 can extend into the grabbing bin 223 . A wedge member 225 is provided on the working end of the telescopic member 224 , and the wedge member 225 can also extend into the grabbing bin 223 .

[0096] In some possible implementations, the telescopic member 224 uses an electric cylinder.

[0097] See also Figure 12 The wedge 225 can be inserted between the substrate and the lifting platform 14 so that the substrate can move with the grab plate 222 .

[0098] In some possible implementations, two groups of telescopic members 224 are used, one group of telescopic members 22 on each side of the grab plate 222 , and the number of telescopic members 22 in each group is two.

[0099] Furthermore, a temperature sensor 226 is mounted on the gripping plate 222. The detection end of the temperature sensor 226 extends into the gripping chamber 223 to detect the temperature of the substrate. During the aforementioned processing, the temperature of the substrate gradually decreases. If the temperature of the substrate falls below the processing requirement, the substrate needs to be heated.

[0100] See also Figure 13 The heating of the substrate is achieved by the heating chamber 31, the electromagnetic coil 32 and the lifter 33. The electromagnetic coil 32 is wound on the inner wall of the heating chamber 31 and is limited in the axial direction of the heating chamber 31. The length of the electromagnetic coil 32 is less than the length of the heating chamber 31.

[0101] Because the lifter 33 is also located within the heating chamber 31, the electromagnetic coil 32 must be long enough to accommodate the lifter 33. After the gripper 22 places the substrate on the lifter 33, the lifter 33 begins to move up and down within the heating chamber 31, and the electromagnetic coil 32 is simultaneously energized, heating the substrate on the lifter 33. The portion of the lifter 33 that enters the electromagnetic coil 32 must be made of a non-metallic material, such as cermet.

[0102] See also Figure 14Furthermore, the heating chamber 31 is divided into a fixed section and a movable section, and the electromagnetic coil 32 is located inside the movable section. A movable module 34 is also added, connected to the movable section, and configured to place the movable section on the fixed section and remove the movable section from the fixed section.

[0103] The moving module 34 drives the moving section to move horizontally, so that the moving section can move away from the fixed section. The main reason is that the moving section will heat up during operation, and it is necessary to prevent the temperature from being transferred to the fixed section and affecting the normal operation of the lifter 33 inside the fixed section.

[0104] Of course, you can also cancel the fixed segment directly at this time.

[0105] For some examples, see Figure 15 and Figure 16 The lifter 33 includes a first lifting cylinder 331, a placement platform 332, a second lifting cylinder 333 and a positioning ring 334. The first lifting cylinder 331 is located in the fixed section, and the placement platform 332 and the second lifting cylinder 333 are both fixed on the first lifting cylinder 331.

[0106] The positioning ring 334 is fixed on the second lifting cylinder 333 , and the placement platform 332 is located inside the positioning ring 334 .

[0107] When the first lifting cylinder 331 rises, the placement platform 332, the second lifting cylinder 333 and the positioning ring 334 all rise, and the same applies when they fall; when the second lifting cylinder 333 rises, only the positioning ring 334 rises, and the same applies when they fall.

[0108] When the substrate is to be placed on the placement table 332 , the positioning ring 334 will rise a certain distance, so that the working surface of the placement table 332 and the inner side surface of the positioning ring 334 can form a groove structure to temporarily fix the substrate.

[0109] After the heating is completed, the positioning ring 334 returns to the initial position, and the grabbing robot 22 grabs the substrate and puts it back to the forging die 23.

[0110] The cylinders mentioned in the above content are preferably hydraulic cylinders. For some parts that only provide movement, electric cylinders can be used.

[0111] This application also discloses a hoe production process, the specific steps of which are as follows:

[0112] The plate is subjected to annular edge forging to obtain a base material and a waste material;

[0113] Measuring the temperature of the substrate, and heating the substrate when the temperature of the substrate does not meet the requirements;

[0114] Forging and shaping the base material whose temperature meets the requirements;

[0115] The ferrule is placed on the forged and shaped base material and then welded to make the ferrule and the forged and shaped base material become one.

[0116] The above steps have been introduced when describing the hoe production line and will not be repeated here.

[0117] 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.
