Description

Technical Field

[0001] The present application relates to the technical field of industrial production equipment, and in particular to a continuous forging production line for producing hoes. Background Art

[0002] In the current hoe manufacturing process, the raw materials used are mostly rail steel, rail profiles and discarded rails. The specific production method is to divide the raw materials, heat them, and then shape them, and finally weld them together with the connecting sleeve or directly make holes on the finished product.

[0003] The above process involves many manual steps. The main reasons include the need for frequent heating during forging, the lack of supporting forming dies, and the difficulty in picking up high-temperature forgings. Among them, the difficulty in picking up high-temperature forgings is a major factor affecting production automation.

[0004] This is because the high-temperature forgings are small in size, and the bottom surface is basically completely in contact with the forging table. It is difficult to grab them directly with a robot, and there is a risk of them falling. There have been methods of using magnets for adsorption and grabbing, but magnets have the problem of failure at high temperatures. This problem is unavoidable and has a certain degree of unpredictability, and cannot be applied to automated production processes. Summary of the invention

DETAILED DESCRIPTION

[0049] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0050] This application discloses a continuous forging production line for producing hoes, see Figure 1 The continuous forging production line for producing hoes disclosed in the present application includes a forging table 1, a shaping sleeve 2, a sliding adjustment member 3, a sliding channel 4, a driving module 5 and a heating module 6.

[0051] See also Figure 1 and Figure 2 The forging table 1 includes a forging platform 11 and a plurality of forging stands 12. The plurality of forging stands 12 are sequentially arranged on the forging platform 11. There are gaps between adjacent forging stands 12. Each forging stand 12 is responsible for a forging process.

[0052] exist Figure 2 It can be seen that in the moving direction of the forging, the working area of ​​the forging stand 12 gradually increases. This is because during the continuous forging process, the forging begins to gradually take shape, and the working area of ​​the forging stand 12 needs to increase with the forging process so that the forging is finally formed.

[0053] The working area refers to the contact area between the forging stand 12 and the forging.

[0054] See also Figure 3 and Figure 4 The shaping sleeve 2 is slidably connected to the forging stand 12, and is responsible for cooperating with the working surface (top surface) of the forging stand 12 to produce a forging cavity on the forging stand 12. The forging cavity has a shaping effect on the forging. Under the hammering of the forging equipment, the forging will deform and fill the forging cavity.

[0055] The reason for using the shaping sheath 2 is that the forging needs to be moved sequentially through each forging stand 12, so it is necessary for the forging cavity to appear when the forging is forged, but disappear when the forging moves.

[0056] The movement process of the shaping sheath 2 is realized by the sliding adjustment member 3 , which is installed on the forging table 1 . The working surface of the sliding adjustment member 3 has an arc-shaped protrusion, which is used to drive the corresponding shaping sheath 2 to slide.

[0057] In some examples, the sliding adjustment member 3 includes a wedge-shaped driving body 31 and a telescopic driver 32 , and the arc-shaped protrusion is located on the working surface (top surface) of the wedge-shaped driving body 31 . The wedge-shaped driving body 31 is slidably connected to the forging table 1 and is respectively located on both sides of the forging stand 12 .

[0058] The telescopic driver 32 is fixedly mounted on the forging platform 11 and connected to the wedge-shaped driver 31 . The function of the telescopic driver 32 is to drive the wedge-shaped driver 31 to move in the horizontal direction.

[0059] In some possible implementations, there are at least three sliding adjustment members 3 below a shaping sheath 2, including two sliding adjustment members on the left or front side and one sliding adjustment member on the right or rear side.

[0060] In some possible implementations, the telescopic drive 32 uses a hydraulic cylinder.

[0061] See also Figure 5 In some possible implementations, the wedge-shaped driving body 31 includes a base body 311 and a wedge-shaped body 312 ( Figure 5 The dotted line in the figure indicates the wedge-shaped body 312), a detachable and fixedly connected wedge-shaped body 312 is used here in order to adjust the movement amount of the shaping sheath 2 in the vertical direction.

[0062] The change in the movement of the shaping sleeve 2 can change the height of the forging cavity, so that it can be used to produce products of different thicknesses. When the size of the product changes, the forging stand 12 and the matching shaping sleeve 2 need to be replaced.

[0063] The sliding channel 4 is located between two adjacent shaping sleeves 2, and both ends of the sliding channel 4 are connected to the adjacent shaping sleeves 2. The forging cavities mentioned in the above content can be connected together in sequence through the sliding channel 4, so that the forgings can pass through each forging cavity (forging stand 12) in sequence.

[0064] The forging parts are sequentially passed through each forging cavity (forging stand 12) by the drive module 5, see Figure 6The driving module 5 includes a longitudinal lifting driving frame 51, a transverse slide 52 and a toggle arm 53. The longitudinal lifting driving frame 51 is arranged parallel to the forging platform 11 and can be installed on the forging table 1 or directly on the ground. The transverse slide 52 is arranged on the longitudinal lifting driving frame 51 and is slidably connected to the longitudinal lifting driving frame 51.

[0065] Specifically, the longitudinal lifting drive frame 51 is composed of a base, a longitudinal telescopic arm (an electric cylinder in the longitudinal telescopic arm, Figure 6 The two ends of the longitudinal telescopic arm are respectively connected to the base and the crossbeam, so that the crossbeam can reciprocate (raise and lower) in the longitudinal direction. The transverse slide 52 is composed of a slide slidably connected to the crossbeam and a transverse telescopic arm installed on the crossbeam. The transverse telescopic arm is also connected to the slide, so that the slide can reciprocate (move left and right) in the horizontal direction.

[0066] The number of the toggle arms 53 is the same as the number of the forging platforms 11 . Each forging platform 11 is equipped with a toggle arm 53 . The toggle arms 53 are arranged at intervals on the transverse slide 52 .

[0067] The working path of the toggle arm 53 (taking the forging moving from left to right as an example) is: descending to contact with the left side of the forging - moving right to push the forging to move to the next forging platform 11 - moving up to contact with the left side of the forging - resetting.

[0068] For some examples, see Figure 7 The toggle arm 53 includes a first toggle arm 531 and a second toggle arm 532 connected to the first toggle arm 531. The first toggle arm 531 and the second toggle arm 532 are vertically arranged. The reason for using two toggle arms (the first toggle arm 531 and the second toggle arm 532) is that the forging needs to be heated by the heating module 6, and the toggle arm 53 cannot come into contact with the induction coil 62.

[0069] This requires the toggle arm 53 to provide a sufficient pushing distance. In the present application, the pushing distance is achieved by a first toggle arm 531 and a second toggle arm 532 that are vertically arranged.

[0070] For some possible implementations, see Figure 8 The second toggle arm 532 includes a driver 5321 disposed on the first toggle arm 531 and a slide rod 5322 slidably connected to the first toggle arm 531 , and the telescopic end of the driver 5321 is connected to the slide rod 5322 .

[0071] The use of the driver 5321 here can shorten the distance of the second toggle arm 532, and thus shorten the distance between the two forging platforms 11, which can shorten the moving distance of the forging and reduce the temperature loss of the forging and the power consumption of the heating module 6 to a certain extent.

[0072] The heating module 6 is arranged on the sliding channel 4 to heat the forging. It should be understood that the forging needs to maintain a certain temperature during the forging process, but the temperature of the forging will drop during the process of sequentially passing through each forging platform 11 and being forged at each forging platform 11.

[0073] Therefore, it is necessary to heat the forged parts before each forging. In the previous production method of manual forging, the staff used tools to place the forged parts back into the furnace for heating. However, in the automated production method provided by this application, this placement and heating method is no longer applicable because the moving path of the forged parts is fixed and cannot be changed.

[0074] In order to solve this problem, the present application uses a heating module 6 to heat the forging part. The heating module 6 includes an induction coil driver 61 and an induction coil 62 electrically connected to the induction coil driver 61. The induction coil 62 is mounted on the corresponding sliding channel 4 and is suspended and fixed using a bracket.

[0075] At this time, the material of the sliding channel 4 needs to be a non-magnetic material, such as stainless steel or some alloy materials, and the induction coil driver 61 is directly placed on the ground on one side of the sliding channel 4 or on the equipment placement table.

[0076] For some examples, see Fig.10 The shaping sleeve 2 includes a shaping section 21 and a guide section 22, and the specific size requirements are as follows: in the direction away from the forging platform 11, the size of the inner hole on the shaping section 21 remains unchanged, and in the direction away from the forging platform 11, the size of the inner hole on the guide section 22 tends to increase.

[0077] The shaping section 21 is used to participate in forming the forging cavity, and the guide section 22 is used to guide the forging piece to ensure that the forging piece can enter the forging cavity.

[0078] In some examples, the sliding channel 4 is connected to the inner hole of the shaping sleeve 2, so as to guide the moving path of the forging with the help of the inner hole wall of the shaping sleeve 2 to prevent the forging from sliding in a direction perpendicular to the moving path.

[0079] For some examples, see Figure 7There is also a blower 54 on the transverse slide 52, and the blower 54 is used to remove metal debris on the forging platform 11, and there is a blower 54 behind each toggle arm 53 in the working direction of the toggle arm 53.

[0080] It should be understood that during the forging process, oxides will fall off the surface of the forged part. If these oxides fall on the forging platform 11, they may adhere to the next forged part, causing the surface of the forged part to be uneven. Therefore, they need to be blown away by the blower 54.

[0081] In some possible implementations, the blower 54 includes a base, a universal tube and a nozzle. The base is fixed on the transverse slide 52. Both ends of the universal tube are respectively connected to the base and the nozzle. There is a channel on the base, and the channel is connected to the compressed air source.

[0082] In some other possible implementations, the purge device 54 is composed of two parts: a pipeline and a purge pipe, and both ends of the pipeline are connected to the purge pipe and the compressed air source respectively.

[0083] For some examples, see Fig. 9 A temperature sensor 63 is installed on the sliding channel 4. The temperature sensor 63 is electrically connected to the induction coil driver 61. Its function is to feed back the temperature of the forging to the induction coil driver 61, so that the heating power of the induction coil driver 61 can be adjusted according to the temperature of the forging.

[0084] For example, the temperature of the forging entering the sliding channel 4 is T1, and the temperature of the forging when it moves to the next forging platform 11 is T2, T1 is a variable, T2 is a constant, and the heating power of the induction coil driver 61 needs to be determined based on the temperature difference (T2-T1), and the temperature difference is a variable.

[0085] The temperature sensor 63 is used to detect T1.

[0086] In some possible implementations, each induction coil driver 61 is electrically connected to an independent temperature sensor 63 .

[0087] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
