Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a track turnout forging device which is easy to demould. Background Art

[0002] Railway turnouts are an important part of railway lines. They are a line connection device that allows locomotives and vehicles to transfer from one track to another. They are also one of the weak links of the track. They are usually laid in large quantities at stations and marshaling yards. With turnouts, the line's capacity can be fully utilized. Even for single-track railways, laying turnouts and building a fork line that is longer than the length of the train can allow trains to run in opposite directions.

[0003] The manufacture of turnouts, i.e. rails, generally adopts the hot forging method, i.e., the hot working die integral cavity die forging. First, the automatic feeding device of the forging production line grabs the rails and sends them to the induction heating furnace for heating. After the heating is completed, the automatic feeding device sends the rails to the die. During the process of feeding the rails into the die, the automatic feeding device flips the rails to the appropriate angle to cooperate with the die for pressing; the slider moves downward for pressing and then returns; after the slider presses, the automatic feeding device moves the forged rails out of the press and then moves them to the unloading area on the other side of the press.

[0004] For rails that are large parts, demoulding is mostly done mechanically. Demolding involves the use of a release agent, which is usually done by manual periodic brushing. In the actual forging process, due to the high temperature of the mold cavity, in order to avoid scalding the operator, it is generally necessary to wait for complete cooling before proceeding. This is inconvenient and has safety hazards. At the same time, the release agent is affected by various factors, and its replenishment cycle is uncertain.

[0021] Supplementary explanation based on the above structure is as follows: the release agent storage box 41 contains release agent, and the pump body 42 is used to extract the release agent in the release agent storage box 41 and input it into the spray barrel 44 through each input hole 431, and spray it to the outside through each spray hole 441.

[0022] Further, such as Figure 5 As shown, a reflux cylinder 443 is provided in the spray cylinder 44, the upper side of the reflux cylinder 443 is open, and a reflux hole 444 is provided on the lower side of the reflux cylinder 443, and an output hole 432 is provided in the fixed plate 43 in coordination with the reflux cylinder 443, and the output hole 432 is connected to a pump body 45, and the output end of the pump body 45 is connected to the release agent storage box 41.

[0023] In one embodiment, a plurality of hoses 445 are connected to the lower side of the reflux tube 443 .

[0024] In actual operation, pump body 1 42 is used to extract the release agent and spray it into the mold of the forging device through the spray barrel 44, and pump body 2 45 is used to recover the excess release agent in the mold through the reflux hole 444 on the lower side of the reflux barrel 443 and the hose 445, among which the reflux hole 444 serves as the main reflux inlet of the release agent, and each hose 445 can cooperate with the irregular internal structure of the mold as an auxiliary reflux inlet that can explore the complex structure, so as to realize comprehensive recovery.

[0025] like Figures 10-11 As shown, a partition plate 1 411 and a partition plate 2 412 are fixed in the release agent storage box 41, a solenoid valve 413 is connected between the partition plate 1 411 and the partition plate 2 412, the lower side of the partition plate 1 411 is set as a storage chamber 414, the storage chamber 414 is connected to the pump body 1 42, and the upper side of the partition plate 2 412 is set as a filter chamber 415, and the filter chamber 415 is connected to the pump body 2 45.

[0026] Furthermore, a filter screen 4151 is provided in the filter chamber 415, a pressure sensing module is provided at the fixed end of the filter screen 4151, a partition box 416 is provided on the upper side of the filter screen 4151, two screw rods 4152 are rotatably provided on the partition box 416, the bottom surfaces of the partition boxes 416 located on both sides of the filter screen 4151 are lower than the plane where the filter screen 4151 is located, and the corresponding space is set as a partition chamber 4161, and a filter plate 4162 is provided on the contact side of the partition chamber 4161 and the filter chamber 415, one end of the screw rod 4152 extending out of the partition box 416 is connected to a motor 4153, a brush plate 4154 is passed through the screw rod 4152 and is threadedly matched therewith, and the brush surface of the brush plate 4154 fits the surface of the filter screen 4151.

[0027] In actual operation, when the pump body 45 inputs the release agent into the filter chamber 415, the release agent is filtered out by the filter screen 4151 to remove the impurities entrained therein and then deposited at the bottom of the filter chamber 415, and the solenoid valve 413 is opened to transport the filtered release agent back to the storage chamber 414; during the filtration period, the pressure sensing module of the filter screen 4151 detects the pressure state to determine the filtering state of the release agent; when the motor 4153 is working, the screw 4152 will drive the brush plate 4154 to move back and forth on the surface of the filter screen 4151, thereby dredging the mesh of the filter screen 4151, and the partition chamber 4161 is used to store the impurities brushed off from the filter screen 4151, and the filter plate 4162 is used to separate the residual release agent in the partition chamber 4161.

[0028] In one embodiment, preferably, Figures 6 to 9 As shown, an airflow hood 5 is arranged on the outside of the spray barrel 44, and an airflow inlet 51 and an airflow outlet 52 are opened on the airflow hood 5. A plurality of booster plates 446 are obliquely arranged on the surface of the spray barrel 44 located inside the airflow hood 5, and the airflow inlet 51 is connected to the air pump 6.

[0029] Furthermore, a plurality of airflow outlets 53 are provided on the lower side of the airflow hood 5, a gear sleeve 54 is provided on the rotating sleeve at the bottom of the airflow hood 5, the outer periphery of the gear sleeve 54 is provided with a side tooth structure, a connecting port 541 is provided on the lower side of the gear sleeve 54 to cooperate with the airflow outlet 53, a blocking block 542 is provided on the upper side of the gear sleeve 54 to cooperate with the airflow outlet 1 52, the gear sleeve 54 is transmission-connected with a driving tooth 71, and the driving tooth 71 is connected to a motor 2 72.

[0030] Supplementary explanations based on the above structure are as follows: in one mode, the connecting port 541 of the gear sleeve 54 does not correspond to each airflow outlet port 2 53. At this time, the lower side of the airflow hood 5 is in a closed state, and the blocking block 542 is separated from the airflow outlet port 1 52, and the airflow outlet port 1 52 is connected to the outside. When the air pump 6 inputs gas into the airflow hood 5, the airflow pushes the booster plate 446 to drive the spray tube 44 to rotate, and the gas in the airflow hood 5 is output from the airflow outlet port 1 52; in another mode, the motor 2 72 drives the gear sleeve 54 to rotate through the driving tooth 71, so that the connecting port 541 corresponds to each airflow outlet port 2 53, and the blocking block 542 blocks the airflow outlet port 1 52. At this time, the gas input into the airflow hood 5 will be output from the airflow outlet port 2 53, thereby realizing the change of the airflow output direction.

[0031] like Figure 2 As shown, the drive module 2 includes a longitudinal slide rail 21, a motor three 22, a screw two 23, a fixed block 24, a screw drive module 25 and a movable frame 26, wherein the fixed block 24 is mounted on the bogie 3, the screw two 23 is threadedly matched with the fixed block 24 and both ends are rotatably set on the slide rail 21, the motor three 22 is fixed on the slide rail 21 and the driving end is connected to the screw two 23, the screw drive module 25 is fixed on the lower side of the slide rail 21, the movable frame 26 is fixed on the driving end of the screw drive module 25, and the fixed plate 43 is mounted on one end of the movable frame 26.

[0032] In actual operation, the motor three 22 drives the screw two 23 to rotate, so that the slide rail 21 as a whole can move up and down relative to the fixed block 24, thereby realizing longitudinal movement; the screw drive module 25 is used to drive the mobile frame 26 to move horizontally, and the drive module 2 can realize the adjustment of the fixed plate 43 in two directions.

[0033] like Figure 1 As shown, the forging device includes a bottom box 81, a lower frame 82 is fixedly installed on the upper surface of the bottom box 81, a lower die 83 is arranged above the lower frame 82, guide columns 84 are fixed through the four right angles of the lower frame 82, the top of the guide column 84 is fixedly connected with an upper box 85, a hydraulic cylinder 86 is arranged on the upper box 85, an upper frame 87 is fixed to the driving end of the hydraulic cylinder 86, and the outer surfaces of the upper box 85 and the hydraulic cylinder 86 are provided with reinforcing rib structures to provide structural strength, the bottom of the upper frame 87 is fixedly connected with an upper die, the output end of the hydraulic cylinder 86 can drive the upper die to move up and down through the upper frame 87, and the lower die 83 and the upper die are closed to realize the forging process of metal steel.

[0034] Before forging, the spray assembly 4 applies a release agent to the lower die 83, and the specific steps are as follows: Step 1: Cleaning. The driving module 2 drives the fixing plate 43 to move into the slot of the lower die 83. First, the blocking block 542 blocks the first air outlet 52. At this time, the second air outlet 53 corresponds to the communication port 541, and the air output direction is adjusted downward. The air pump 6 starts to input air into the air hood 5. The driving module 2 controls the movement of the fixing plate 43 to make the air blow to the inner surface of the lower die 83 to peel off the residual impurities on its surface. Step 2: Spraying. After the lower die 83 is cleaned, control the blocking block 542 to leave the first air outlet 52. At this time, the second air outlet 53 corresponds to the communication port 541, and the air output direction is adjusted horizontally. The air pushes the booster plate 446, causing the spraying cylinder 44 to start rotating. At the same time, the first pump body 42 inputs the release agent into the spraying cylinder 44, and sprays it onto the surface of the lower die 83 through each spraying hole 441. Step 3: Recycling. After spraying a certain amount of release agent, the air pump 6 and the first pump body 42 stop working. The driving module 2 controls the spraying cylinder 44 to move down close to the bottom of the lower die 83, and the second pump body 45 starts. The deposited release agent is pumped back to the release agent storage tank 41 through the output hole 432 and the hose 445 for treatment. Step 4: Die casting. After the release agent is coated, the spraying assembly 4 resets, and the forging device feeds materials and performs the die casting process.

[0035] Specifically, in Step 1, when cleaning the side of the lower die 83, the driving module 2 drives the spraying cylinder 44 to move down so that part of the second air outlet 53 can be aligned with the side of the lower die 83, and then moves along the side wall direction to complete the cleaning process of the side. When cleaning the bottom of the lower die 83, the driving module 2 drives the spraying cylinder 44 to move down to a position close to the bottom, and then moves along the covered range of the bottom to complete the cleaning process of the bottom. The general travel route is set manually. To avoid errors, a visual detection module can be added to the lower side of the fixing plate 43 to assist each process.

[0036] In Step 3, the pressure sensing module of the filter screen 4151 can judge whether the excess release agent accumulated at the bottom of the lower die 83 has been recycled according to the change of the pressure signal. When the release agent is introduced above the filter screen 4151, the pressure sensing module can detect a pressure signal F1 that is significantly greater than the initial pressure F0. And in the state of having the release agent, F1 is within a stable range. After the excess release agent is extracted, because no additional release agent is input to exert pressure on the filter screen 4151, the detected pressure value by the pressure sensing module starts to gradually decrease and stabilizes at the final pressure F2, F0 < F2 < F1. At this time, it is determined that the excess release agent has been extracted. Further, after judging that the release agent has been extracted, compare the final pressure signal F2 with the initial pressure signal F0 to judge whether there is too much filter residue on the surface of the filter screen 4151, and establish a comparison coefficient a, a ≥ 1. When F0 ≤ F2 < a * F0, the impurities accumulated on the filter screen 4151 are appropriate and will not affect the subsequent filtration. When F2 ≥ a * F0, too many impurities are accumulated on the filter screen 4151. To avoid clogging of the mesh holes and reduce the filtration efficiency, the brush plate 4154 is activated to sweep the impurities into the partition chamber 4161.
