Description

Technical Field

[0001] The invention belongs to the technical field of bearing processing, and in particular relates to a high-speed press bimetallic bearing and a manufacturing device thereof. Background Art

[0002] High-speed press bimetallic bearings are a key component specifically designed for use in high-speed presses. Their key feature is their bimetallic construction, typically composed of two layers of different metals: an inner and outer layer of a highly wear-resistant and compressive alloy, and an outer layer of a softer metal. Through the optimal combination of these metals, bimetallic bearings achieve a balanced balance of strength and wear resistance under high-speed, high-pressure, and heavy-load conditions, enhancing their overall performance.

[0003] In practice, bimetallic bearings in high-speed presses are subject to long-term high-speed rotation and heavy loads, making them susceptible to surface wear, structural fatigue, and delamination of the bonded layer. During the bearing manufacturing process, issues such as a weak bond between the alloy layer and the base metal, residual impurities, or oxide scale on the surface can affect the bearing's overall performance and service life. Furthermore, traditional processes struggle to effectively strengthen and thoroughly clean the bearing surface, making it prone to failure during subsequent use and difficult to ensure reliability and stability.

[0004] In addition, existing preparation equipment is difficult to achieve efficient, uniform and thorough surface grinding and impurity removal for key components such as steel back sleeves, resulting in unstable product quality and affecting the reliability and production efficiency of bearings.

[0005] In summary, the existing high-speed press bimetallic bearings and their preparation devices have problems that need to be improved in terms of structural performance, surface treatment, etc. There is an urgent need for a new technical solution that can achieve efficient cleaning, surface strengthening and effective separation of impurities to improve the overall performance and production efficiency of the bearings. Summary of the Invention

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a bimetallic bearing for a high-speed press, comprising a bearing base, and further comprising a coupling ring rotatably connected to the inner wall of the bearing base.

[0007] A manufacturing device for a high-speed press bimetallic bearing, comprising: S1. Raw material selection: generally high-strength steel or cast iron is used as the base material of the bearing; S2. Base metal treatment: treating the surface of the base metal to remove the oxide layer and impurities, ensuring that the metal surface is smooth and clean for bonding with the alloy layer; S3, melt casting, heating the copper-based alloy to the melting point, and then pouring it on the surface of the base metal; S4, hot extrusion, the base metal coated with the alloy layer is subjected to a hot extrusion process to form a closer bond between the alloy layer and the base metal; S5. Machining: remove burrs and impurities generated during the machining process to ensure the structural integrity of the bearing and improve its reliability.

[0008] A manufacturing device for a high-speed press bimetallic bearing includes a fixed box, a grinding mechanism, the grinding mechanism being arranged in the fixed box, the grinding mechanism including a plurality of connecting blocks arranged on the fixed box, the grinding mechanism being used to continuously grind the steel back sleeve in all directions so that impurities on the steel back sleeve are fully removed, and a separation mechanism, the separation mechanism being arranged in the fixed box, the separation mechanism including an annular groove arranged on the fixed box, the separation mechanism being used to separate the impurities ground off the steel back sleeve from the shot blasting, thereby achieving continuous grinding. When performing surface grinding on the steel back sleeve, the steel back sleeve to be ground is first placed inside a circular cylinder, then the drive motor is started, and an appropriate amount of shot blasting material is poured into the funnel plate. The shot blasting material enters the feed barrel through the funnel plate in turn, and is evenly distributed into the circular box through the arc groove under the limiting guidance of the conical block, thereby achieving stability and uniformity of the initial distribution.

[0009] Preferably, the polishing mechanism includes several connecting blocks fixedly mounted on the inner wall of the fixed box, the tops of several connecting blocks are fixedly mounted with connecting boxes, the inner wall of the connecting box is fixedly mounted with a circular cylinder, and the bottom of the fixed box is fixedly mounted with a driving motor.

[0010] Preferably, a rotating shaft is fixedly installed on the output end of the driving motor, a circular plate is fixedly installed on the top of the fixed box, a circular box is fixedly installed on the top of the circular plate, and the top end of the rotating shaft extends into the circular box and is rotatably connected to the circular box.

[0011] Preferably, a plurality of fan blades are fixedly mounted on the outer wall of the rotating shaft, and the driving motor drives the rotating shaft to rotate. A plurality of fan blades are mounted on the rotating shaft. When the fan blades rotate at high speed and contact the shot blasting, the shot blasting will be thrown out of the shot blasting trough at high speed under the action of strong centrifugal force. The high-speed moving shot blasting hits the surface of the steel back sleeve, effectively removing impurities, oxide scale and other pollutants attached to its surface, thereby achieving efficient cleaning and surface strengthening treatment. A plurality of shot blasting troughs are provided on the outer wall of the circular box, a plurality of arc-shaped grooves are provided on the top of the circular box, a feeding barrel is fixedly mounted on the top of the circular box, a conical block is fixedly mounted on the top of the circular box, and a funnel is slidably mounted in the feeding barrel. Plate, the outer wall of the funnel plate is in contact with the inner wall of the circular cylinder, and the rotation of the rotating shaft also drives the circular rotating plate connected thereto to rotate synchronously, and the circular rotating plate drives the circular rotating plate to rotate through the connecting rod, and the circular rotating plate further drives multiple steel back sleeves to rotate synchronously. This rotation design enables the steel back sleeve to continuously change its position during the grinding process, ensuring that each surface can be fully covered by shot blasting, thereby improving the uniformity and integrity of the grinding. More importantly, under the action of the centrifugal force generated during the rotation of the circular rotating plate, the steel back sleeve will rotate close to the inner wall of the circular cylinder, maintaining a stable grinding distance, thereby effectively controlling the grinding quality and avoiding problems such as uneven striking or damage to the workpiece caused by position offset.

[0012] Preferably, the separation mechanism includes an annular groove provided on the circular cylinder, an annular limit box is fixedly installed on the outer wall of the circular cylinder, and an arc-shaped limit box is fixedly installed on the outer wall of the annular limit box, and the circular cylinder is communicated with the annular limit box and the arc-shaped limit box. The shot blasting after grinding and the detached impurities will fall into the fixed box below from the inclined groove at the bottom of the circular cylinder. By utilizing the differences in shape, mass and movement characteristics between the shot blasting and the impurities, the system can realize the recycling and reuse of the shot blasting and the automatic discharge of impurities through the centrifugal separation structure, preventing impurities from participating in the grinding process again, thereby further ensuring the stability and consistency of the grinding effect. In summary, the present invention realizes multiple functions such as automatic feeding, uniform distribution, high-speed shot blasting, all-round rotation grinding and centrifugal limiting of the steel back sleeve through a mechanical linkage structure, which not only improves the grinding efficiency and consistency, but also significantly improves the grinding quality and the automation level of the equipment, and has good application prospects and promotion value.

[0013] Preferably, a circular rotating plate is rotatably installed in the circular cylinder, a plurality of inclined grooves are opened on the circular rotating plate, a circular rotating plate is fixedly installed on the rotating shaft, the circular rotating plate rotates and passes through the fixed box, and a plurality of pushing plates are fixedly installed on the top of the circular rotating plate. During the grinding process of the steel back sleeve, the high-speed shot blasting will knock off the impurities attached to the surface of the workpiece after hitting the surface of the workpiece, and then the used shot blasting and the fallen impurities will fall from the inclined groove at the bottom of the circular cylinder into the fixed box below. The shot blasting and impurities falling into the fixed box will contact the circular rotating plate linked to it, and as the circular rotating plate continues to rotate , and several pushing plates arranged on it also rotate accordingly, and under the action of centrifugal force, the shot and impurities are thrown to the inner wall of the fixed box together. Since the shot is regular spherical and has a large mass, while the impurities are mostly irregular in shape and light in mass, the two show different behavioral characteristics during the movement. Under the guidance of centrifugal force and the inclined surface inside the fixed box, the shot rolls along the arc path into the arc limit box and finally enters the circular rotating plate area. Subsequently, the shot re-enters the circulation system through the funnel plate and continues to grind the steel back sleeve, realizing efficient recycling and reuse, thereby reducing material loss and improving grinding efficiency.

[0014] Preferably, two connecting rods are fixedly installed on the top of the circular rotating plate, and the top ends of the two connecting rods are in contact with the circular rotating plate. Several discharge troughs are provided at the bottom of the fixed box. Due to their irregular shape and light weight, impurities cannot enter the circulation path smoothly like shot blasting. Under the guidance of the internal limiting structure of the fixed box, they slide along the set downward channel and are finally discharged uniformly through the discharge trough, completing effective separation from the shot blasting. This design not only realizes the automatic recovery and recycling of shot blasting materials, but also effectively prevents impurities from flowing back to the grinding area, avoiding secondary pollution or scratches on the surface of the steel back sleeve, thereby further improving the stability, cleanliness and sustainability of the entire shot blasting grinding system.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) When grinding the steel back sleeve, first put the steel back sleeve into the circular cylinder, then start the drive motor and pour an appropriate amount of shot into the funnel plate. The shot will enter the feed cylinder from the funnel plate and be evenly dispersed into the circular box through the arc groove under the limiting action of the conical block. The drive motor will drive the rotating shaft to rotate, and the rotating shaft will drive several fan blades to rotate. When the fan blades come into contact with the shot, they will throw the shot out of the throwing groove at high speed under the strong centrifugal force. The thrown shot will come into contact with the steel back sleeve and knock off the impurities on the steel back sleeve. When the rotating shaft rotates, it will drive the circular rotating plate to rotate. The circular rotating plate will drive the circular rotating plate to rotate under the action of the connecting rod. The circular rotating plate will drive several steel back sleeves to rotate synchronously. Under the action of rotation, the different adjustment positions of the steel back sleeve are convenient for comprehensive grinding of shot blasting. At the same time, the centrifugal force generated when the circular rotating plate rotates will keep the steel back sleeve rotating along the inner wall of the circular cylinder, maintaining the grinding distance and controlling the grinding quality.

[0016] (2) During the grinding process, after the shot blasting contacts the steel back sleeve, the shot blasting will enter the fixed box from the inclined slot together with the impurities falling from the steel back sleeve. The falling shot blasting and impurities will contact the circular rotating plate. During the rotation of the circular rotating plate, it will drive several push plates to rotate. Under the action of centrifugal force, the push plates drive the shot blasting and impurities to be thrown onto the inner wall of the fixed box. Since the shot blasting is spherical and the impurities are irregular and light in weight, the corresponding shot blasting will roll into the arc limit box and the circular rotating plate under the action of the inclined surface of the fixed box and the centrifugal force, and then enter the funnel plate from the circular rotating plate to continue grinding the steel back sleeve, playing the role of cyclic grinding. The corresponding impurities will slide down under the limiting action of the fixed box until they are discharged from the discharge chute to complete separation, thereby ensuring that the impurities will not enter the circular cylinder again and affect the grinding effect.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 6 As shown, the present invention provides a high-speed press bimetallic bearing, comprising a bearing base 41, and further comprising; The inner wall of the bearing base 41 is rotatably connected to a coupling ring 42 .

[0021] A device for manufacturing a bimetallic bearing for a high-speed press includes a fixing box 1 and: The grinding mechanism is arranged in the fixed box 1. The grinding mechanism includes a plurality of connecting blocks 101 arranged on the fixed box 1. The grinding mechanism is used to continuously grind the steel back sleeve in all directions so that impurities on the steel back sleeve are fully removed. The separation mechanism is arranged in the fixed box 1. The separation mechanism includes an annular groove 2 arranged on the fixed box 1. The separation mechanism is used to separate the impurities ground off the steel back sleeve from the shot blasting to achieve continuous grinding.

[0022] The grinding mechanism includes several connecting blocks 101 fixedly mounted on the inner wall of the fixed box 1, a connecting box 102 is fixedly mounted on the top of the several connecting blocks 101, a circular cylinder 103 is fixedly mounted on the inner wall of the connecting box 102, and the steel back sleeve and shot blasting are placed and closed in the circular cylinder 103. A driving motor 104 is fixedly mounted on the bottom of the fixed box 1 to continuously adjust the position of the steel back sleeve to achieve comprehensive grinding of the steel back sleeve.

[0023] Adopt the above scheme: when grinding the steel back sleeve, first place the steel back sleeve into the circular cylinder 103, then start the drive motor 104 and pour an appropriate amount of shot into the funnel plate 113, and the shot will enter the feed cylinder 111 from the funnel plate 113.

[0024] A rotating shaft 105 is fixedly installed on the output end of the driving motor 104, a circular plate 106 is fixedly installed on the top of the fixed box 1, a circular box 107 is fixedly installed on the top of the circular plate 106, and the top of the rotating shaft 105 extends into the circular box 107 and is rotatably connected to the circular box 107.

[0025] The above scheme is adopted: the driving motor 104 drives the rotating shaft 105 to rotate, and a plurality of fan blades 108 are installed on the rotating shaft 105. When the fan blades 108 rotate at high speed and contact the shot, the shot is thrown out from the throwing trough 109 at high speed under the action of strong centrifugal force. The high-speed moving shot hits the surface of the steel back sleeve, effectively removing impurities, oxide scale and other pollutants attached to its surface, thereby achieving efficient cleaning and surface strengthening treatment.

[0026] A number of fan blades 108 are fixedly installed on the outer wall of the rotating shaft 105, a number of casting grooves 109 are opened on the outer wall of the circular box 107, a number of arc grooves 110 are opened on the top of the circular box 107, a feed barrel 111 is fixedly installed on the top of the circular box 107, a conical block 112 is fixedly installed on the top of the circular box 107, a funnel plate 113 is slidably installed in the feed barrel 111, and the outer wall of the funnel plate 113 is in contact with the inner wall of the circular barrel 103.

[0027] Using this solution, a suitable amount of shot blasting material is poured into the funnel plate 113. The shot blasting material then passes through the funnel plate 113 and into the feed barrel 111. Guided by the conical block 112, the material is evenly distributed through the arcuate groove 110 into the circular box 107, achieving a stable and uniform initial distribution. Upon contact with the shot blasting material, the blades 108, under the powerful centrifugal force, fling the shot blasting material away from the chute 109 at high speed. The ejected shot blasting material then contacts the steel backing sleeve, knocking off impurities therefrom.

[0028] like Figures 1 to 6 As shown, the separation mechanism includes an annular groove 2 opened on the circular cylinder 103, an annular limit box 201 is fixedly installed on the outer wall of the circular cylinder 103, an arc-shaped limit box 202 is fixedly installed on the outer wall of the annular limit box 201, and the circular cylinder 103 is communicated with the annular limit box 201 and the arc-shaped limit box 202.

[0029] Adopting the above scheme: Since the shot is regular spherical and has a large mass, while the impurities are mostly irregular in shape and light in mass, the two exhibit different behavioral characteristics during the movement. Under the guidance of centrifugal force and the inclined surface inside the fixed box 1, the shot rolls along the arc path into the arc limit box 202 and finally enters the circular rotating plate 203 area.

[0030] A circular rotating plate 203 is rotatably installed in the circular cylinder 103, and a plurality of inclined slots 204 are opened on the circular rotating plate 203. A circular rotating plate 205 is fixedly installed on the rotating shaft 105. The circular rotating plate 205 rotates through the fixed box 1, and a plurality of pushing plates 206 are fixedly installed on the top of the circular rotating plate 205.

[0031] Adopting the above scheme: during the grinding process of the steel back sleeve, the high-speed shot will knock off the impurities attached to it after hitting the surface of the workpiece. Subsequently, the used shot and the fallen impurities fall into the fixed box 1 below from the inclined groove 204 at the bottom of the circular cylinder. The shot and impurities falling into the fixed box 1 will contact the circular rotating plate 205 linked to it. As the circular rotating plate 205 continues to rotate, the several push plates 206 arranged on it also rotate, and under the action of centrifugal force, the shot and impurities are thrown toward the inner wall of the fixed box 1.

[0032] Two connecting rods 207 are fixedly installed on the top of the circular rotating plate 205. The top ends of the two connecting rods 207 are in contact with the circular rotating plate 203. A plurality of discharge slots 208 are provided at the bottom of the fixed box 1.

[0033] Adopting the above scheme: due to the irregular shape and light weight of impurities, they cannot enter the circulation path smoothly like shot blasting. Under the guidance of the internal limiting structure of the fixed box 1, they slide along the set downward channel and are finally discharged uniformly through the discharge trough 208, completing effective separation from the shot blasting. This design not only realizes the automatic recovery and recycling of shot blasting materials, but also effectively prevents impurities from flowing back to the grinding area, avoiding secondary contamination or scratches on the surface of the steel back sleeve, thereby further improving the stability, cleanliness and sustainability of the entire shot blasting grinding system.

[0034] The working principle and use process of the present invention are as follows: when the steel back sleeve is subjected to surface grinding, the steel back sleeve to be ground is first placed inside the circular cylinder 103, and then the driving motor 104 is started, and an appropriate amount of shot blasting material is poured into the funnel plate 113. The shot blasting material enters the feeding cylinder 111 through the funnel plate 113 in turn, and is evenly distributed to the circular box 107 through the arc groove 110 under the limiting guidance of the conical block 112, ensuring the stability of the material distribution process and the uniformity of the shot blasting distribution. The driving motor 104 drives the rotating shaft 105 to rotate, and a number of fan blades 108 are installed on the rotating shaft 105. When the fan blades 108 rotate at high speed and contact the shot blasting, the shot blasting will be thrown out of the throwing groove 109 at high speed under the action of strong centrifugal force. The high-speed moving shot blasting hits the surface of the steel back sleeve, effectively removing impurities, oxide scale and other pollutants attached to the surface, thereby achieving efficient cleaning and surface strengthening treatment. At the same time, the rotation of the rotating shaft 105 also drives the circular rotating plate 205 connected to it to rotate synchronously. The circular rotating plate 205 drives the circular rotating plate 203 to rotate through the connecting rod 207, and the circular rotating plate 203 further drives multiple steel back sleeves to rotate synchronously. This rotation design allows the steel back sleeve to continuously change its position during the grinding process, ensuring that all surfaces can be fully covered by shot blasting, thereby improving the uniformity and integrity of the grinding. More importantly, under the action of the centrifugal force generated during the rotation of the circular rotating plate 203, the steel back sleeve will rotate closely against the inner wall of the circular cylinder 103, maintaining a stable grinding distance, thereby effectively controlling the grinding quality and avoiding the problems of uneven impact or damage to the workpiece caused by position offset. In addition, in order to improve the automation level and environmental protection performance of the equipment, the polished shot and the detached impurities will fall from the chute 204 at the bottom of the circular cylinder into the fixed box 1 below. By utilizing the differences in shape, mass and movement characteristics between the shot and the impurities, the system can realize the recycling and reuse of the shot and the automatic discharge of impurities through the centrifugal separation structure, preventing impurities from participating in the grinding process again, thereby further ensuring the stability and consistency of the grinding effect. During the grinding process of the steel back sleeve, the high-speed shot will knock off the impurities attached to it after hitting the surface of the steel back sleeve. Then, the used shot and the fallen impurities fall into the fixed box 1 below from the inclined groove 204 at the bottom of the circular cylinder. The shot and impurities falling into the fixed box 1 first contact the circular rotating plate 205 linked to it. As the circular rotating plate 205 continues to rotate, the several pushing plates 206 arranged on it also rotate accordingly, and under the action of centrifugal force, the shot and impurities are thrown to the inner wall of the fixed box 1 together. Since the shot is a regular spherical shape and has a large mass, while the impurities are mostly irregular in shape and have a light mass, the two exhibit different behavioral characteristics during the movement. Under the guidance of centrifugal force and the inclined surface inside the fixed box 1, the shot rolls along the arc path into the arc limit box 202, and finally enters the circular rotating plate 203 area. Then, the shot passes through the funnel plate 113 again. New impurities enter the feeding system and continue to grind the steel back sleeve to achieve efficient recycling and reuse, thereby reducing material loss and improving grinding efficiency. At the same time, due to their irregular shape and light weight, impurities cannot enter the circulation path smoothly like shot blasting under the action of centrifugal force. Under the guidance of the internal limiting structure of the fixed box 1, they slide along the set downward channel and are finally discharged uniformly through the discharge trough 208 to complete effective separation from the shot blasting. This design effectively prevents impurities from flowing back into the grinding area, avoiding secondary pollution or scratches on the surface of the steel back sleeve, thereby further improving the stability, cleanliness and sustainability of the entire shot blasting grinding system. In addition, in order to ensure that the shot blasting can smoothly return to the grinding process, the design of the arc limit box 202 not only helps to guide the shot blasting to re-enter the circular rotating plate 203, but also can cushion the impact of the shot blasting to a certain extent, reduce equipment wear and extend service life.
