Description

Technical Field

[0001] The present invention relates to the technical field of forging, and more specifically, to a forging device for a railway bridge bearing plate. Background Art

[0002] The bridge bearing plate is an important component of the bridge structure, used to connect the superstructure and substructure of the bridge. It is located between the bridge and the pad stone, and can reliably transfer the load and deformation borne by the bridge superstructure to the bridge substructure. It is an important force transmission device of the bridge. Bridge bearing plates come in many forms, including asphalt felt or flat plate bearings, plate rubber bearings, spherical bearings, steel bearings and special bearings. Among them, plate rubber bearings are a common form. They are made of several layers of thin rubber sheets and thin steel plates inlaid, bonded and pressed. They have sufficient vertical stiffness to withstand vertical loads, and can adapt to the rotation of the beam end and meet the horizontal displacement of the superstructure.

[0003] In the related art, when using forging equipment to bend and press a flat support plate, the plate is generally first conveyed to the heating furnace position by a conveyor belt, and then lifted to the heating position by a lifting mechanism, and then two heating furnaces are used to heat both ends of the plate at the same time, and then the plate is sent to the pressing mechanism for pressing and bending.

[0004] However, the lifting mechanism provided in the existing forging equipment generally provides stable support for the plate by making surface contact with the plate. When the bottom of the plate is uneven, the surface contact may cause the plate to tilt to a certain extent on the lifting mechanism, making it unstable. At the same time, when the two ends of the plate are heated, the plate will deform to a certain extent. At this time, the tilt of the plate may become larger, and the stability of the plate may further deteriorate. The heated area at both ends of the unstable plate is prone to change during the heating process, which leads to differences in the heating effect at both ends of the plate. Under the action of internal stress, it is easy to cause the plate to deform to a large extent after heating, which is not conducive to subsequent further bending and pressing.

DETAILED DESCRIPTION

[0031] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0032] Please refer to Figure 1 and Figure 2A railway bridge bearing plate forging equipment comprises: a conveyor belt 1, a lifting mechanism 2 and a pressing mechanism 3. The lifting mechanism 2 is installed below the end of the conveyor belt 1, and is used to lift the plate moved to the end position of the conveyor belt 1 to a heating position. The pressing mechanism 3 is located on one side of the end of the conveyor belt 1. A heating furnace 4, a clamping mechanism 5 and a feeding mechanism 6 are respectively arranged between the end of the conveyor belt 1 and the pressing mechanism 3. The heating furnace 4 is two symmetrically distributed movable electric heating furnaces 4. The heating furnace 4 is used to heat the two ends of the plate at the heating position. The clamping mechanism 5 is used to transfer the heated plate to the feeding mechanism 6. The clamping mechanism 5 can be a mobile trolley with a hydraulic clamping arm. The feeding mechanism 6 is used to transport the plate to the pressing mechanism 3. On the top, the feeding mechanism 6 can be a mobile feeding trolley, the pressing mechanism 3 is used to press the plate, the lifting mechanism 2 includes a telescopic driving member 21 and a supporting member 22, the supporting member 22 is connected to the telescopic end of the telescopic driving member 21, the supporting member 22 includes a lifting plate 221, an adjusting member and a plurality of telescopic members, the plurality of telescopic members are distributed on the upper surface of the lifting plate 221 according to a preset arrangement, the adjusting member is connected to the plurality of telescopic members, and is used to adjust the telescopic ability of the telescopic member so that the telescopic member has a variety of usage states, and a plurality of telescopic members jointly provide point-contact support for the bottom of the plate; in the process of heating the plate, telescopic members with different telescopic abilities are used to match the plate in the corresponding state to maintain the stable state of the plate.

[0033] During the forging process of the plate, the plate is moved to its end position through the conveyor belt 1 and aligned with the lifting mechanism 2 below. The plate is lifted up by the lifting mechanism 2 to separate it from the conveyor belt 1. During the lifting process, the top ends of several telescopic parts are in point contact with the bottom of the plate at the same time. If the bottom of the plate is not flat enough, the compression telescopic parts will shrink accordingly. The adaptive expansion and contraction of the telescopic parts can keep the plate in a horizontal state, thereby ensuring the stability of the plate. When the plate reaches the set heating position, the two electric heating furnaces 4 move closer, so that the two ends of the plate extend into the heating chamber of the electric heating furnace 4 respectively. Since the default expansion and contraction capacity of the telescopic parts in the initial state is relatively small, that is, the compressive resistance is relatively strong, at this time, since the deformation amount of the plate each time is small, in order to further The step is to adapt to the deformation of the plate during the heating process. By controlling the activity of the adjusting part, the telescopic ability of the telescopic part is adjusted to increase its telescopic ability, that is, the compressive resistance is weakened. When the plate is heated, it is deformed, and the deformation position can continue to compress the telescopic part. Through the further adaptation of the telescopic part, the plate can continue to remain stable. After the heating is completed, the heated plate is clamped by the clamping mechanism 5 and transferred to the feeding mechanism 6, and then transported to the pressing mechanism 3 by the feeding mechanism 6. Finally, the plate is pressed and formed by the pressing mechanism 3. When the plate is separated from the top of the telescopic part, the telescopic part is automatically reset with the help of its own elasticity. At the same time, the adjusting part is controlled to adjust the telescopic part to restore it to the initial telescopic ability state, and continue to operate on the next plate.

[0034] In the lifting mechanism 2 provided in the present invention, a plurality of telescopic parts are provided to make point contact with the bottom of the plate as a support. When the bottom of the plate is not flat enough, the uneven position can directly squeeze the corresponding telescopic part to adapt to the contraction, thereby avoiding rigid contact between the plate and the telescopic part, so that the plate can maintain a horizontal state, which is beneficial to improving the problem of tilting when the plate is placed; and by providing an adjusting part to adjust the telescopic ability of the telescopic part, when the plate is heated, the telescopic ability of the telescopic part is increased so that it can adapt well to the slight deformation of the plate, further maintaining the balance of the plate, improving the stability of the plate during heating, and making the heated areas at both ends of the plate basically consistent, so as to improve the problem of large deformation of the plate; in addition, when the mass of the plate changes, the telescopic ability of the telescopic part can also be adjusted by the adjusting part, so that the telescopic part can match the mass of the plate well, avoiding the telescopic part from losing its adaptive support function.

[0035] Please refer to Figure 2 As an embodiment of the present invention, the telescopic driving member 21 is a hydraulic cylinder, the bottom of the hydraulic cylinder is fixedly connected to the bottom of the conveyor belt 1, and the telescopic end of the hydraulic cylinder is fixedly connected to the center position of the bottom of the lifting plate 221.

[0036] Please refer to Figure 3As an embodiment of the present invention, the telescopic member includes a limit rod 222 and a contact push rod 223. The limit rod 222 is fixedly installed in the lifting plate 221, and the contact push rod 223 is slidably sleeved on the top end of the limit rod 222. The top end of the contact push rod 223 slides upward from the inside of the lifting plate 221 and passes through the top of the lifting plate 221. Two symmetrical limit grooves are provided on the outer side of the limit rod 222. The inner side of the contact push rod 223 is slidably connected to the limit groove through two protrusions, which can prevent the contact push rod 223 from rotating relative to each other; the outer annular surface of the top end of the contact push rod 223 is arc-shaped, which is used to reduce the contact area with the plate; the outer side of the limit rod 222 is sleeved with a support spring 224, and the top end of the support spring 224 is connected to the bottom end of the contact push rod 223. The elastic coefficient of the support spring 224 and the number of contact push rods 223 , needs to be set according to actual usage conditions, and the condition that needs to be met is that after the plate is placed, the displacement of the support spring 224 does not exceed one half; the adjusting member includes a cylinder 225 and a movable plate 226, the cylinder 225 is fixedly installed in the lifting plate 221, the bottom of the movable plate 226 is fixedly connected to the telescopic end of the cylinder 225, the outer side of the movable plate 226 is slidably connected to the inside of the lifting plate 221, and a plurality of through holes 227 corresponding to the limit rod 222 are opened on the top of the movable plate 226, the bottom end of the limit rod 222 extends to the bottom of the movable plate 226 through the through hole 227, and a plurality of bottom support ring bodies 228 corresponding to the through holes 227 are fixedly installed on the top of the movable plate 226, the support ring body 228 is movably sleeved on the outer side of the limit rod 222, and the top of the support ring body 228 is connected to the bottom end of the support spring 224.

[0037] When the lifting mechanism 2 is in use, the plate reaches its upper position and the hydraulic cylinder is extended to drive the lifting plate 221, the telescopic member and the adjusting member to move upward synchronously. When the top of the contact push rod 223 contacts the bottom of the plate, the bottom of the plate generates downward pressure on the telescopic member, causing the contact push rod 223 to begin to slide downward along the outer side of the limit rod 222 and squeeze the support spring 224. Since each contact rod contacts different points on the bottom of the plate, the corresponding contact rod can be squeezed to adapt to the uneven position. In this way, the plate can remain horizontal on the plane formed by multiple contact push rods 223. After that, the plate follows the lifting mechanism 2 to move upward and separates from the conveyor belt 1. After reaching the heating position, the hydraulic cylinder stops extending. , start to adjust the telescopic capacity of the telescopic part, so that the elastic coefficient of the support spring 224 becomes smaller, and the cylinder 225 contracts, which can drive the movable plate 226 to move downward synchronously, and then the support ring body 228 moves downward. At this time, since the mass of the plate has not changed, the pressure on the support spring 224 has not changed. When the support ring body 228 moves downward, the bottom end of the support spring 224 synchronously follows the extension, so that the support spring 224 extends downward for a distance, while the position of the plate remains unchanged. During the heating process of the plate, if the plate undergoes a slight deformation, the contact top rod 223 at the deformation position adapts to the contraction, which can further adapt to the deformation process of the plate, so that the plate can still maintain its original horizontal and stable state.

[0038] The present invention sets a telescopic member and an adjusting member for use in conjunction, so that the telescopic member has a state adjustment function. According to different processing states of the plate, the telescopic member can be synchronously and adaptively adjusted, which is beneficial to maintaining the effective supporting effect of the telescopic member. At the same time, the adjusting member can adjust multiple telescopic members at the same time, which is beneficial to maintaining the consistency of the adjustment amount of the telescopic member, thereby maintaining the supporting effect of the plate unchanged and making the adjustment operation more convenient.

[0039] Please refer to Figure 4 and Figure 5As an implementation mode of the present invention, in order to further improve the adaptability of the telescopic member and better match the processing of the plate, the present invention continues to optimize the telescopic member, specifically: two connecting protrusions 229 staggered up and down are fixedly installed at both ends of the inner wall of the through hole 227, and the lower end of the outer side of the limiting rod 222 is provided with a track groove 2210 adapted to the connecting protrusion 229, and the bottom end of the limiting rod 222 is rotatably connected with the inside of the lifting plate 221. When the two connecting protrusions 229 slide in cooperation with the track groove 2210, the limiting rod 222 rotates with the contact top rod 223, and the top of the lifting plate 221 is embedded with a plurality of contact top rods. The cleaning brush 2211 corresponds to the rod 223; the track groove 2210 includes a spiral groove and two vertical grooves, the spiral groove is located below the vertical groove, the two vertical grooves are symmetrically distributed on both sides of the limiting rod 222, the bottom end of the vertical groove is connected to the upper end of the spiral groove, and the two connecting protrusions 229 are slidably connected to the two vertical grooves accordingly. The vertical groove is set as a path for the connecting protrusion 229 to move downward synchronously along the outer side of the limiting rod 222, and can limit the rotatable limiting rod 222 so that it will not rotate relative to each other, and the contact top rod 223 will not rotate during the process of adjusting the telescopic capacity.

[0040] When the plate being processed is too heavy and exceeds the maximum load-bearing capacity of the telescopic member, the telescopic member can no longer be used and needs to be adjusted to a retracted state. The lifting plate 221 provides support for the plate. When adjusted to the retracted state, the cylinder 225 contracts, driving the movable plate 226 and the support ring body 228 to move downward together, and the bottom end of the support spring 224 first follows the support ring body 228 to extend synchronously. After the support spring 224 returns to its natural state, the support spring 224 and the contact push rod 223 move downward together, and the connecting protrusion 229 slides downward along the vertical groove, and moves past the contact push rod 223. During the cleaning process, its lower end first contacts with the cleaning brush 2211, and after the connecting protrusion 229 enters into the spiral groove, the two connecting protrusions 229 and the spiral groove cooperate to drive the limiting rod 222 and the contact top rod 223 to rotate. Through the rotation of the contact top rod 223, the cleaning brush 2211 can comprehensively clean its surface. Since the cleaning brush 2211 has a certain elasticity, it can also clean the top of the contact top rod 223 until the contact top rod 223 is completely retracted into the lifting plate 221, the cylinder 225 stops retracting, and the contact top rod 223 and the limiting rod 222 no longer rotate.

[0041] The present invention sets a cleaning brush 2211, a connecting protrusion 229 and a track groove 2210 for use together. When the contact top rod 223 is folded up, the outer side and the top of the contact top rod 223 can be cleaned simultaneously, and the adsorbed impurities and dust can be removed, so that the contact top rod 223 maintains a certain degree of cleanliness without manual cleaning. When it is used next time, it can directly contact the plate to avoid dust and impurities affecting the contact effect of the temperature of the two. Therefore, the lifting component set in the present invention can not only realize point contact support with the plate, but also can synchronously adapt and adjust according to the processing state of the plate. It can also be completely folded up when not in use, which will not affect the use of the lifting plate 221. It is very flexible to use and can well match the processing process of the plate.

[0042] Please refer to Figure 6 As an embodiment of the present invention, since the plate may be offset during placement or transportation, and the offset plate will cause the two ends of the plate to extend into the electric heating furnace 4 in an inconsistent state, resulting in different heating areas at both ends of the plate, the present invention continues to optimize the above scheme, specifically: the lifting mechanism 2 also includes a correction component 23, the correction component 23 is arranged on the outside of the hydraulic cylinder, the correction component 23 includes a connecting plate 231, a driving member and two correction members, the connecting plate 231 is fixedly sleeved on the outside of the telescopic end of the hydraulic cylinder, the two correction members are respectively arranged at both ends of the connecting plate 231, and are used to perform extrusion-type position correction on the plate at the end of the conveyor belt 1, the top of the correction member is higher than the top of the telescopic member, the driving member is connected to the two correction members, and is used to drive the two correction members to move closer to or away from each other; the correction member includes a contact plate 232 and a sliding plate 233, the sliding plate 233 is slidably installed on the top of the connecting plate 231, the contact plate 232 is installed at one end of the sliding plate 233, and the top of the contact plate 232 is provided with a correction inclined surface. The driving component includes a driving motor 234, which is fixedly mounted on one end of the connecting plate 231. The rotating end of the driving motor 234 is fixedly connected to a screw rod 235. One end of the screw rod 235 is rotatably connected to the other end of the connecting plate 231. The two ends of the outer side of the screw rod 235 are provided with thread grooves with opposite thread directions. The tops of the two sliding plates 233 are respectively threadedly connected to the two ends of the outer side of the screw rod 235.

[0043] When the correction component 23 is in use, during the extension of the hydraulic cylinder, the connecting plate 231 and the correction member can move up with the hydraulic cylinder. When the correction inclined surface at the top of the contact plate 232 contacts both sides of the plate, if the plate is offset, the inclined surfaces on the two contact plates 232 respectively contact the two ends of the plate, and the plate can be squeezed to move toward the middle. When the two ends of the plate can contact the inclined surfaces of the correction member at the same time, the plate can restore the standard posture. After that, by driving the motor 234 to rotate, the screw rod 235 can drive the two sliding plates 233 to move away synchronously, and the two contact plates 232 also move away synchronously. At this time, the plate gradually moves downward along the inclined surface at the top of the contact plate 232 until the contact plate 232 is completely separated from the plate, and the bottom of the plate just contacts the top of the telescopic member, and the telescopic member provides support for the plate.

[0044] The present invention provides a correction component 23, which is mainly used to adjust the posture of the plate by contacting the correction component with the end of the plate before lifting the plate, thereby realizing the position correction function of the plate, so that the plate is always in a standard posture before being lifted, which is beneficial to avoid the problem of uneven heating at both ends of the plate due to non-standard placement of the plate.

[0045] Please refer to Figure 7 and Figure 8 As an embodiment of the present invention, after the plate is heated, carbides are present on the upper and lower surfaces of the plate. In order to further clean these carbides, the present invention provides a cleaning member, specifically: the correction member 23 also includes a cleaning member, and the cleaning member includes a transmission gear 236, a tooth plate 237 and a scraper plate 238; the transmission gear 236 is fixedly mounted on the bottom of the contact plate 232, the bottom of the transmission gear 236 is rotatably connected to the top of the sliding plate 233, the tooth plate 237 is fixedly mounted on the top of the connecting plate 231, one side of the tooth plate 237 is meshed with the outer side of the transmission gear 236, and the scraper plate 238 is movably mounted. Installed on the top of the contact plate 232, a connecting rod 239 is fixedly installed on the bottom of the scraper plate 238, and a compression spring 2310 is mounted on the outer side of the connecting rod 239. The two ends of the compression spring 2310 are respectively fixedly connected to the inner side of the contact plate 232 and the outer side of the connecting rod 239. A rising block 2311 is slidably installed inside the sliding plate 233, and an inclined panel 2312 is fixedly installed on the bottom of the connecting plate 231. The rising block 2311 is adapted to the inclined surface of the inclined panel 2312. After the contact plate 232 is separated from the plate, the rising block 2311 can be moved to contact the inclined surface of the inclined panel 2312.

[0046] After the plate is heated, the cleaning piece is used to clean the carbide produced on the top and bottom of the plate. The driving motor 234 rotates to continue to drive the two sliding plates 233 away from each other, and the rising block 2311 gradually moves up along the inclined surface of the inclined plate 2312 by sliding contact with the inclined plate 2312, so that the connecting rod 239 drives the scraper plate 238 to move up synchronously, and the compression spring 2310 is compressed synchronously, and the scraper plate 238 begins to separate from the contact plate 232. When the rising block 2311 moves to the horizontal section of the inclined plate 2312, the sliding plate 233 continues to move, and the rising block 2311 no longer moves up, so that the scraper plate 238 no longer moves up. At this time, the gap between the scraper plate 238 and the contact plate 232 is adapted to the thickness of the plate. During the movement of the sliding plate 233, the transmission gear 236 gradually approaches the part with teeth of the tooth plate 237 until the scraper plate 238 stops moving up, and the transmission gear 236 is just meshed with the tooth plate 237. As the gear continues to move, the transmission gear 236 is meshed with the tooth plate 237. The contact plate 232 continues to move, so that the transmission gear 236 rotates along one side of the tooth plate 237, and drives the contact plate 232 and the scraper plate 238 to swing, so that the gap between the contact plate 232 and the scraper plate 238 gradually approaches the heating end of the plate and contacts the top and bottom of the plate respectively. As the contact plate 232 swings, the carbide on the top and bottom of the heating end of the plate can be scraped off. When the scraper plate 238 swings to the other side of the plate, the driving motor 234 stops rotating and then rotates in the opposite direction, so that the scraper plate 238 swings in the opposite direction and scrapes the carbide on the plate again. The scraping times of the scraper plate 238 can be adjusted according to actual use requirements. When cleaning is completed, the contact plate 232 and the sliding plate 233 are moved and reset by the rotation of the driving motor 234, and the tooth plate 237 is separated from the transmission gear 236. Under the elastic force of the compression spring 2310, the scraper plate 238 synchronously follows the downward movement and resets, and finally fits with the top of the contact plate 232.

[0047] The present invention can scrape and clean the carbides on the heated plate by arranging a cleaning piece on the correcting piece. Through the coordinated use of the scraper plate 238, the connecting rod 239, the rising block 2311 and the inclined plate 2312, and utilizing the movement of the sliding plate 233 as a driving force, the scraper plate 238 can be unfolded and swung successively, so that the scraper plate 238 and the contact plate 232 can clean the carbides on the plate. The contact plate 232 is not only used to correct the posture of the plate, but also used in conjunction with the scraper plate 238 to realize the cleaning function of the plate, so that the lifting mechanism 2 has the lifting, position correction and cleaning functions at the same time, and is well suitable for the use requirements of plate heating.

[0048] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
