Description

TECHNICAL FIELD

[0001] The embodiment of the present disclosure relates to the technical field of automatic production, in particular to a multi-zone coordinated special-shaped rail forging and pressing automatic production device and method. BACKGROUND

[0002] In the past decade, domestic switch manufacturers have developed their own special-shaped rail automatic production lines. Generally, they use automatic feeding mechanisms to displace the rails and use different mold forms of automatic mold forging and pressing designs to improve the efficiency of rail forging and pressing. However, for many years, there has been no good solution to the rail feeding method. After the rail is hoisted by the manual crane, the existing feeding method uses a single feeding method of the feeding rack. The difference lies in that some use a feeding trolley to feed the first step for heating, and then the trolley takes the material; some use a feeding mechanism in front of the furnace to directly take the material and then heat it in the furnace for forging and pressing production.

[0003] The above two methods do not refine the operation process and work steps for the feeding process, resulting in that in actual operation, the rail crane hoisting, placing and pushing process cannot be coordinated due to the interference of human operation and equipment operation, and on the other hand, the entire feeding process is unreasonable and unscientific, without any rail displacement precision and state control design, and without any flexible rail pushing buffer reaction force scheme, which leads to the fact that the actual rail position state cannot be stabilized to meet the position precision and rhythm of the feeding trolley equipment. In actual application, the feeding efficiency of the automatic production line is very low. There are long-term problems in rail stacking, horizontal displacement asynchronization, difficulty in ensuring equal distance between rails, unreliable rail pushing operation, poor continuous production connection, slow continuous production rhythm of multiple rails, frequent pushing chain breakage and other long-term feeding operation problems.

[0004] Therefore, it is necessary to improve one or more problems in the related technical solutions.

DETAILED DESCRIPTION

[0053] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations can, however, be implemented in many different forms and should not be construed as limited to the examples set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the scope of example implementations to those skilled in the art. The described features, structures, or characteristics can be combined in one or more implementations.

[0054] In addition, the drawings are only schematic illustrations of embodiments of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus repeated descriptions thereof will be omitted. Some of the block diagrams shown in the drawings are functional entities, which do not necessarily have to correspond to physically or logically independent entities.

[0055] In the present example embodiment, a multi-zone coordinated irregular rail forging and pressing automatic production device is first provided. Referring to Figure 1 illustrated in FIG. 1,

[0056] A plurality of storage racks 100 are arranged parallel to each other on one side of the heating furnace 600 along the conveying direction of the rail pieces to be processed and are connected by a through shaft 130. The area between the plurality of storage racks 100 forms a storage area and a feeding area. The storage area is used to store the rail pieces to be processed, and the feeding area is used for feeding the rail pieces to be processed in the storage area.

[0057] A plurality of material placing racks 200 are arranged in the same direction as the storage racks 100 and are arranged at intervals between the plurality of storage racks 100. The area between the plurality of material placing racks 200 forms a material placing area for placing a plurality of rail pieces to be processed.

[0058] The material placing rack 200 and the storage rack 100 are respectively provided with a material pushing mechanism 300. The material pushing mechanism 300 on the material placing rack 200 is arranged on the material placing rack 200 by a material pushing driving mechanism 700 and is used to place a plurality of rail pieces to be processed in the material placing area at equal intervals during reciprocating movement along the conveying direction of the rail pieces to be processed.

[0059] The material pushing mechanism 300 on the storage rack 100 is arranged on the material placing rack 200 by a material pushing driving mechanism 700 and is used to push a plurality of rail pieces to be processed placed in the material placing area one by one to a material preparation area during reciprocating movement along the conveying direction of the rail pieces to be processed. The rail pieces to be processed in the material preparation area are horizontally positioned by a horizontal positioning mechanism 150. The material preparation area and the material placing area constitute the storage area.

[0060] A feeding mechanism 500 is arranged between the two storage racks 100 close to the heating furnace 600. The feeding mechanism 500 is used to longitudinally position the rail pieces to be processed in the feeding area and to perform feeding and discharging operations of the rail pieces to be processed in the heating furnace 600.

[0061] The heating furnace 600 is used to heat the end of the rail pieces to be processed entering the heating furnace 600.

[0062] The forging mechanism is arranged on the side away from the heating furnace 600, and is used for forging the heated part of the rail to be processed.

[0063] Through the above device, on the one hand, the four areas are reasonably divided during the feeding process: the storage area and the feeding area formed between the storage racks 100, the placing area formed between the placing racks 200, and the standby area in the storage area except the placing area. On the other hand, through the connection work between the storage racks 100, the placing racks 200, the feeding mechanism 500, the heating furnace 600, the forging mechanism and the like, the actual operation range of each area is flexibly overlapped and crossed, so that the continuous production of the complete operation of storage, placing, standby, feeding and forging is realized through the complementary connection of the functions in different areas. The problems of low feeding efficiency, mutual stacking of long rails, asynchronous horizontal movement, difficulty in ensuring equal distance between the rails to be processed, and the like are effectively overcome. Through the replacement of the horizontal positioning cylinder with the pushing mechanism, the pushing mechanism is directly horizontally positioned, the frequency of breaking of the pushing chain 710 of the rails to be processed is reduced, and the failure of the trolley to take the rails to be processed caused by unreliable pushing operation and the like is eliminated.

[0064] In the following, the above-mentioned multi-zone coordinated special-shaped rail forging automation production device in the example embodiment will be described in more detail. Figures 1 to 13 The above-mentioned multi-zone coordinated special-shaped rail forging automation production device in the example embodiment will be described in more detail.

[0065] In one embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the multi-zone coordinated special-shaped rail forging automation production device includes a plurality of storage racks 100, a plurality of placing racks 200, a feeding mechanism 500, a heating furnace 600 and a forging mechanism. The plurality of storage racks 100 are arranged in parallel along the conveying direction of the rails to be processed on one side of the heating furnace 600, and all the storage racks 100 are connected together through a through shaft 130. The surfaces of the plurality of storage racks 100 jointly form a storage area and a feeding area. The length of the storage rack 100 is greater than the length of the placing rack 200, the conveying direction of the rails to be processed is consistent with the length direction of the storage rack 100, the storage area is used for storing the rails to be processed, and the feeding area is used for feeding the rails to be processed. The plurality of placing racks 200 are arranged between the plurality of storage racks 100, and the arrangement direction of the placing rack 200 is consistent with that of the storage rack 100. The surfaces of the plurality of placing racks 200 jointly form a placing area.

[0066] In one embodiment, as shown in Figure 1 , Figure 2 and Figure 4As shown, in the material placing area, the material placing rack 200 is provided with a stroke box, the stroke box is provided with a pushing driving mechanism 700, the pushing driving mechanism 700 of the material placing rack 200 is provided with a pushing mechanism 300, the pushing driving mechanism 700 of the material placing rack 200 can drive the pushing mechanism 300 to reciprocate along the conveying direction of the to-be-processed rail piece, and further, during the reciprocating process, a plurality of to-be-processed rail pieces in the material placing area are placed at equal intervals according to the preset equal interval, so that the plurality of to-be-processed rail pieces are placed at equal intervals. The storage rack 100 is also provided with a stroke box, the stroke box is provided with a pushing driving mechanism 700, the pushing driving mechanism 700 of the storage rack 100 is provided with a pushing mechanism 300, the pushing driving mechanism 700 of the storage rack 100 can drive the pushing mechanism 300 to reciprocate along the conveying direction of the to-be-processed rail piece, and further, since the material preparation area can only accommodate one to-be-processed rail piece, during the reciprocating process, the plurality of to-be-processed rail pieces placed are pushed one by one to the material preparation area, and after being pushed to the material preparation position, the to-be-processed rail pieces are transversely positioned by the transverse positioning mechanism 150. Among them, the material preparation area and the material placing area constitute a storage area.

[0067] It should be noted that, as Figure 1 As shown, a plurality of storage racks 100 are connected in series through the through shaft 130 and are controlled by the same storage motor, that is, the storage motor is connected to the driving mechanism on all the storage racks 100, so that the same storage motor can control the pushing operation of the pushing mechanism 300. Unlike the storage rack 100, a plurality of material placing racks 200 are controlled by different separate material placing motors, that is, each material placing motor is connected to the driving mechanism on the corresponding material placing rack 200, so that each material placing motor can control the pushing mechanism 300 on the material placing rack 200 to perform the pushing operation according to the situation. Further, all the material placing motors can be synchronously operated or individually operated, that is, the pushing mechanisms 300 on all the material placing racks 200 can be operated together or individually, and the specific operation can be selected according to the actual situation, which is not limited in the embodiment. The number of the plurality of storage racks 100 is 7, and the number of the plurality of material placing racks 200 is 4. The storage racks 100 are numbered as 1-7 from the side close to the heating furnace 600, which facilitates subsequent operation.

[0068] In one embodiment, after the transverse positioning of the to-be-processed rail, the transversely positioned to-be-processed rail enters the feeding area, and the to-be-processed rail in the feeding area is longitudinally positioned by the feeding mechanism 500, so that the end of the to-be-processed rail can smoothly enter the heating furnace 600. After longitudinal positioning, it is sent into the heating furnace 600 by the feeding mechanism 500, and after heating, it is discharged from the furnace again by the feeding mechanism 500. The to-be-processed rail after discharge is conveyed to the forging mechanism by the feeding trolley 800 for forging to form the finished product of the to-be-processed rail. As shown in Figure 3 , since the storage rack 100 is in the shape of a knife and includes a knife body rack 110 and a knife handle rack 120, the knife body rack 110 is connected with the knife handle rack 120, and the lower part of the knife handle rack 120 serves as a position for taking the to-be-processed rail, avoiding interference between the feeding trolley 800 and the storage rack 100. The feeding trolley 800 is also a reciprocating mechanism, and the feeding trolley 800 can be understood with reference to the prior art, and the present embodiment does not limit this.

[0069] It should be noted that the multi-zone coordinated special-shaped rail forging automation production device of the present disclosure can be used in the industry for the automatic operation of to-be-processed rails of two length specifications, i.e., 4860mm-25000mm and 25000mm-50000mm. In addition, in the multi-zone coordinated special-shaped rail forging automation production device of the present disclosure, the operation of feeding the to-be-processed rail in the standby area into the furnace by the feeding mechanism 500 can also be realized by the feeding trolley 800.

[0070] In one embodiment, as shown in Figure 7 , Figure 8 , Figure 9As shown, the pushing mechanism 300 includes a pushing body 310 and a pushing claw 320, the pushing claw 320 is arranged in the pushing body 310 through a rotating horizontal shaft 330, and a torsional spring is sleeved on the rotating horizontal shaft 330, two legs of the torsional spring are connected with the pushing body 310 and the pushing claw respectively, when the pushing mechanism 300 moves forward, the pushing claw 320 extends out of the storage rack 100 or the material swinging rack 200, when the pushing mechanism 300 retreats, the pushing claw 320 is retracted into the storage rack 100 or the material swinging rack 200 under the action of external force. Specifically, the pushing mechanism 300 includes a pushing body 310 and a pushing claw 320, the pushing claw 320 is arranged in the pushing body 310 through a rotating horizontal shaft 330, and a torsional spring is sleeved on the rotating horizontal shaft 330, two legs of the torsional spring are connected with the pushing body 310 and the pushing claw respectively, when the pushing mechanism 300 retreats during the reciprocating movement driven by the pushing driving mechanism 700 on the material swinging rack 200, and when the pushing claw 320 is subjected to the force of the bottom of the to-be-processed rail on the pushing claw 320, the torsional spring is in a compressed state at this time, so that the pushing claw 320 is in a retracted state at this time; when the pushing claw 320 continues to retreat to the bottom of the to-be-processed rail and the force of the to-be-processed rail on the pushing claw 320 disappears, the torsional spring is in an elongated state at this time, so that the pushing claw 320 is in an extended state, when the pushing claw 320 starts to be in an extended state, the pushing mechanism 300 moves forward, because the pushing claw 320 is in an extended state of the material swinging rack 200, the pushing claw 320 pushes the to-be-processed rail in front of the pushing claw 320 forward. Wherein, the pushing claw 320 is a reverse triangular pushing claw.

[0071] In one embodiment, as shown in the drawings, Figure 10 As shown, the pushing body 310 is provided with a concave clamping groove 340 on both sides, and the storage rack 100 and the material swinging rack 200 are respectively provided with a rail 900 for clamping the clamping groove; wherein the concave clamping groove 340 is used for moving along the rail 900. Specifically, the concave clamping groove 340 provided on both sides of the pushing body 310 facilitates the movement of the pushing body 310 along the rail 900 in the storage rack 100 or the material swinging rack 200. Such arrangement makes the movement of the pushing body 310 more stable.

[0072] In one embodiment, as shown in the drawings, Figure 13 As shown, the storage rack 100 away from the heating furnace 600 is provided with a retreat guide plate 140, and the retreat guide plate 140 is used for guiding the discharge of the to-be-processed rail from the heating furnace 600. Specifically, the storage rack 100 away from the heating furnace 600 is provided with a retreat guide plate 140, and the storage rack 100 close to the heating furnace 600 is not provided with a pushing guide plate, which facilitates the guidance of the to-be-processed rail when it is discharged from the heating furnace 600, so that the to-be-processed rail can better perform the retreat operation from the heating furnace 600.

[0073] In one embodiment, the device further comprises:

[0074] A plurality of positioning switches 210 are arranged on each of the material placing racks 200 at preset equal intervals, and the plurality of positioning switches 210 are electrically connected with the material pushing driving mechanism 700 on each of the material placing racks 200, for controlling the material pushing driving mechanism 700 on the material placing rack 200 to drive the material pushing mechanism 300 to place the plurality of to-be-processed rails in the material placing area at equal intervals. Specifically, as shown in Figure 4 each of the material placing racks 200 is provided with a plurality of positioning switches 210 arranged at preset equal intervals, and the plurality of positioning switches 210 on each of the material placing racks 200 are electrically connected with the material pushing driving mechanism 700 on the material placing rack 200, for controlling the material pushing driving mechanism 700 on the material placing rack 200 to drive the material pushing mechanism 300 to place the plurality of to-be-processed rails in the material placing area at equal intervals. In this way, the plurality of positioning switches 210 on each of the material placing racks 200 are used for placing the plurality of to-be-processed rails in the material placing area at equal intervals.

[0075] In one embodiment, the material placing rack 200 is provided with a position detection switch 220, for controlling the forward movement or backward movement of the material pushing mechanism 300 on the material placing rack 200. Specifically, as shown in Figure 4 the position detection switch 220 on each of the material placing racks 200 is used for detecting whether the pushing and grabbing member 320 on the material placing rack 200 has passed through the bottom of the to-be-processed rail, and if the position detection switch 220 detects that the pushing and grabbing member 320 on the material placing rack 200 has passed through the bottom of the to-be-processed rail, the pushing and grabbing member 320 extends out of the material placing rack 200 and pushes the to-be-processed rail forward.

[0076] In one embodiment, the feeding mechanism 500 comprises a feeding rack 510, a material clamping assembly 520 and a feeding driving assembly 530.

[0077] The feeding rack 510 is provided with a transmission shaft 540, one guide rail is arranged on each side of the transmission shaft 540, the feeding driving assembly 530 is connected with the transmission shaft 540, the material clamping assembly 520 is arranged on the transmission shaft 540, and the material clamping assembly 520 reciprocates on the transmission shaft 540. Specifically, as shown in Figure 5 , Figure 6 the feeding driving assembly 530 can be a feeding driving motor, the feeding driving motor is connected with the transmission shaft 540, the feeding driving motor drives the transmission shaft 540 to rotate, and the reciprocating movement of the material clamping assembly 520 is realized by the forward and reverse rotation of the feeding driving motor. Therefore, the process of clamping and reciprocating the to-be-processed rail by the material clamping assembly 520 realizes the forward and backward movement of the to-be-processed rail, that is, the feeding and discharging of the to-be-processed rail into the furnace.

[0081] The feeding mechanism 500 is provided with a confirmation switch 560 for controlling the pushing mechanism 300 on the storage rack 100 to push the to-be-processed rail in the material swinging area to the standby material area, and detecting whether the standby material area has the to-be-processed rail. Specifically, as shown in the figure, Figure 6 ​As shown, the heating furnace 600 is externally provided with a photoelectric switch 550 for longitudinally positioning the rail piece to be processed before being sent to the heating furnace 600, so that the rail piece to be processed can smoothly enter the heating furnace 600. The feeding mechanism 500 is provided with a confirmation switch 560 for detecting whether there is a rail piece to be processed in the standby area, and the confirmation switch 560 is electrically connected with the pushing driving mechanism 700 on the storage rack 100. The confirmation switch 560 is used to control whether the pushing mechanism 300 on the storage rack 100 works. If it is detected that there is no rail piece to be processed in the standby area, the confirmation switch 560 sends a working signal to the pushing driving mechanism 700 on the storage rack 100, and then the pushing driving mechanism 700 on the storage rack 100 drives the pushing mechanism 300 on the storage rack 100 to work, so as to push the rail piece to be processed placed in the standby area to the standby area. If the confirmation switch 560 detects that there is a rail piece to be processed in the standby area, since the standby area can only accommodate one rail piece to be processed at a time, the pushing driving mechanism 700 on the storage rack 100 is controlled to stop working, that is, to stop pushing the rail piece to be processed to the standby area.

[0082] It should be noted that the device further comprises a controller electrically connected with the positioning switch 210, the position detection switch 220, the photoelectric switch 550 and the confirmation switch 560, respectively, and the controller is used to control the opening or closing of the positioning switch 210, the position detection switch 220, the photoelectric switch 550 and the confirmation switch 560.

[0083] In an embodiment, the pushing driving mechanism 700 comprises a chain 710 and a sprocket 720, the chain 710 is sleeved on the sprocket 720, so that the sprocket 720 drives the chain 710 to move, and the pushing mechanism 300 is arranged on the chain 710 and moves with the chain 710. Specifically, as shown in the drawings, Figure 2As shown, the pushing mechanism 700 includes a chain 710 and sprockets 720, and the sprockets 720 are two in number. In addition, the pushing mechanism 700 further includes a rotating shaft 730, and a stroke box is arranged in the storage rack 100.

The pushing mechanism 300 on the placing rack 200 is arranged on the chain 710 and can move with the chain 710, so as to place the several workpieces in the separated state at equal intervals. It should be noted that the stroke box is also provided with a chain 710 limit switch for protecting the limit position of the chain 710.

[0084] The example embodiment also provides a multi-zone coordinated irregular steel rail forging and pressing automatic production method. As shown in Figure 14

[0085] In the step S101, several workpieces to be processed are fed to the placing area formed between the placing racks 200.

[0086] In the step S102, the pushing mechanism 300 on the placing rack 200 is used to place the several workpieces in the separated state at equal intervals in the placing area according to the preset equal intervals, so that the several workpieces after being placed are in the equal interval state.

[0087] In the step S103, the pushing mechanism 300 on the storage rack 100 is used to push the several workpieces after being placed in the placing area one by one to the standby area and perform horizontal positioning, so as to complete the standby work. The standby area can only accommodate one workpiece at a time. When the number of workpieces remaining in the placing area is insufficient, the feeding work is continued.

[0088] In the step S104, the feeding mechanism 500 is used to perform longitudinal positioning on the workpiece after being horizontally positioned in the feeding area, and push the workpiece after being longitudinally positioned into the heating furnace 600 to perform end heating of the workpiece, so as to complete the heating work. After the workpiece in the standby area enters the heating furnace 600, the remaining workpieces in the placing area are pushed one by one to the standby area.

[0089] ​Step S105: After the heating operation, the rail piece to be processed enters the forging mechanism for forging operation to obtain the finished product of the rail piece to be processed.

[0090] Step S106: After the completion of the above-mentioned one-time heating operation, repeat the material preparation operation, heating operation, and continue the forging operation process to form a cycle operation mode.

[0091] In the following, the various parts of the above-mentioned multi-zone coordinated special-shaped steel rail forging automation production method in the present example embodiment will be described in more detail. Figures 1 to 14 In the following, the various parts of the above-mentioned multi-zone coordinated special-shaped steel rail forging automation production method in the present example embodiment will be described in more detail.

[0092] In step S101, a plurality of rail pieces to be processed are loaded onto the material placing area formed between the material placing racks 200. Specifically, before feeding, a plurality of rail pieces to be processed are transported to the storage area formed between the storage racks 100 by the manual trolley. After the manual trolley transports a plurality of rail pieces to be processed to the storage area, the stacked and collapsed rail pieces to be processed may appear. At this time, manual assistance is needed to separate and turn over the stacked and collapsed rail pieces to be processed, and the quantity and number information of the rail pieces to be processed is manually inputted.

[0093] In step S102, the separated plurality of rail pieces to be processed are placed at equal intervals on the material placing area by the pushing mechanism 300 on the material placing rack 200 according to the preset equal interval, so that the plurality of rail pieces to be processed after placement are in an equal interval state. Specifically, after the plurality of rail pieces to be processed are transported to the storage area by the manual trolley and manually separated and turned over, the plurality of material placing racks 200 form a material placing area, and the plurality of rail pieces to be processed after separation and turning over are placed at equal intervals on the material placing area by the pushing mechanism 300 on the material placing rack 200, so that the plurality of rail pieces to be processed after placement are in an equal interval state for subsequent operation.

[0094] In step S103, the pushing mechanism 300 on the storage rack 100 pushes the several rails placed in the placing area to the material preparation area one by one, and performs transverse positioning to complete the material preparation work; wherein, the material preparation area can only accommodate one rail at a time, and when the number of rails left in the placing area is insufficient, the feeding work continues. Specifically, after placing several rails at equal intervals, since the material preparation area can only accommodate one rail, the pushing mechanism 300 on the storage rack 100 pushes the several rails placed one by one to the material preparation area, and after being pushed to the material preparation area, transverse positioning is performed by the transverse positioning cylinder. When the previous rail closest to the material preparation area is pushed to the material preparation area, the pushing mechanism 300 on the placing rack 200 continues to push the next rail on the placing area to the direction close to the material preparation area, so that the next rail fills the space left on the placing area, and the subsequent rails are sequentially pushed in the same way. When the rails left in the placing area are not much, the artificial crane is signaled to transport the next batch of rails to the storage area.

[0095] In step S104, the feeding mechanism 500 longitudinally positions the rails positioned transversely in the feeding area, and pushes the rails positioned longitudinally into the heating furnace 600 to heat the ends of the rails to complete the heating work; wherein, after the rails in the material preparation area enter the heating furnace 600, the remaining rails in the placing area are pushed into the material preparation area one by one. Specifically, after pushing a rail to the material preparation area, the feeding mechanism 500 longitudinally positions the rail, and then pushes the rail positioned longitudinally into the heating furnace 600 to heat the ends of the rail. When longitudinally positioning the rail, the rail can be longitudinally positioned by cooperating with the photoelectric switch 550, and the specific understanding can be referred to the prior art, which will not be described here.

[0096] In step S105, the rails after the heating work enter the forging mechanism to perform forging work to obtain finished products of the rails. Specifically, after completing the end heating work of the rails in the heating furnace 600, the feeding mechanism 500 moves the heated rails out of the heating furnace 600, and then pushes the rails moved out of the heating furnace 600 to the forging mechanism by the feeding trolley 800 to perform forging work to obtain finished products of the rails.

[0097] In step S106, when the above-mentioned one heating operation is completed, the material preparation operation, the heating operation, and the forging operation are repeated to form a cycle operation mode. Specifically, when the rail to be processed in the material preparation area is pushed into the heating furnace 600 by the feeding mechanism 500, the material preparation area is empty at this time, and therefore, the rail to be processed placed in the material preparation area can be continuously pushed into the material preparation area by the pushing mechanism 300 on the storage rack 100 to perform the material preparation operation. When the end of the rail to be processed in the heating furnace 600 is heated, and then the rail to be processed is pushed out by the feeding mechanism 500, and then the rail to be processed is transported to the forging mechanism by the feeding trolley 800 to perform the forging operation, the heating furnace 600 is empty at this time, and therefore, the rail to be processed in the material preparation area can be continuously positioned and fed in the longitudinal direction by the feeding mechanism 500 to complete the end heating operation of the subsequent rail to be processed and continue the forging operation, so that the automatic production of the rail forging can be realized.
