Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for cross wedge rolling mills, in particular to a rolling feeding mechanism for a cross wedge rolling mill. Background Art

[0002] A cross wedge rolling mill is a device for metal plastic processing, mainly used for producing stepped shaft products or blanks with variable cross-sections. By using two wedge-shaped dies installed on co-rotating rolling mills, the blank is subjected to continuous local deformation and finally rolled into various stepped shafts with wedge-shaped profiles.

[0003] Currently, in the production and processing of camshafts, the cross wedge rolling mill is an important processing device. When the existing cross rolling mill feeds materials, it is usually manual feeding. Workers need to take the camshaft from the equipment of one processing procedure on the cross rolling mill to the feeding port of the cross rolling mill. The efficiency of manual transfer of blanks is low, often causing accumulation, which affects the working efficiency of cross wedge rolling production. Summary of the Utility Model

[0004] In order to solve the technical problem of low efficiency of the existing manual transfer of blanks, the utility model provides a rolling feeding mechanism for a cross wedge rolling mill.

[0005] The technical solution of the utility model is realized through the following scheme: A rolling feeding mechanism for a cross wedge rolling mill includes a loading table, a feeding assembly, a buffer receiving table, a driving roller table and a feeding device. The loading table is installed with a feeding assembly, a buffer receiving table and a feeding device. The buffer receiving table is connected to the feeding device through the driving roller table. The feeding assembly is located above the buffer receiving table. A pushing electric cylinder is provided on one side of the buffer receiving table away from the driving roller table.

[0006] Through the above technical scheme, through the cooperation of the driving roller table and the feeding device, the blank can smoothly and continuously enter the rolling area, avoiding the possible pauses and accumulations during manual feeding. The continuous feeding method ensures the smoothness of the production line, thereby improving the overall production efficiency. The buffer receiving table can form a buffer zone between the feeding assembly and the feeding device, effectively alleviating the problem of material accumulation caused by the mismatch between the feeding speed and the production speed. At the same time, the pushing electric cylinder ensures that the blank can enter the next process orderly and accurately.

[0007] Preferably, the feeding assembly includes an external housing, a servo motor, a material blocking roller and a feeding port. The material blocking roller is installed inside the external housing. The material blocking roller is externally connected to the servo motor. The external housing is provided with a feeding port. The feeding port is located on the side wall of the external housing above the material blocking roller. The external housing is installed on the loading table through support legs. The bottom of the external housing is provided with a discharge port.

[0008] Through the above technical solutions, the servo motor drives the material blocking roller to rotate, pushing the blank to the discharge port one by one, reducing production interruptions caused by unsmooth feeding. The close cooperation between the feeding assembly, the buffer receiving table, and the transmission roller path realizes the seamless connection of the blank from feeding to entering the rolling process.

[0009] Preferably, the buffer receiving table includes a bearing plate, a first buffer spring, and a receiving box. The bearing plate is movably installed in the bearing box through the first buffer spring. One side of the bearing box is connected to the transmission roller path, and a pushing electric cylinder is movably installed on the other side of the bearing box.

[0010] Through the above technical solutions, the first buffer spring can absorb and disperse the impact force, reduce the direct impact of the blank on the bearing plate and the entire system, extend its service life, and reduce the noise and vibration generated by the impact, enabling the blank to smoothly transition from the feeding assembly to the transmission roller path. The pushing electric cylinder ensures that the blank can enter the rolling process at a predetermined speed and sequence, improving the continuity and efficiency of the production line.

[0011] Preferably, the feeding device includes a support shell, a speed reduction adjustment assembly, a conveyor chain, and a driving motor. The transmission roller path is lapped on one side of the support shell. A speed reduction adjustment assembly is movably installed on the other side of the support shell. The conveyor chain is installed at the bottom of the support shell, and the conveyor chain is externally connected to the driving motor.

[0012] Preferably, the speed reduction adjustment assembly is inclined.

[0013] Preferably, the speed reduction adjustment assembly includes a speed reduction plate, a second buffer spring, and a damper. The speed reduction plate is inclined and installed on the support shell, and both the second buffer spring and the damper are located between the speed reduction plate and the support shell.

[0014] Preferably, the transmission roller path is lapped on the feeding device through a lapping plate.

[0015] Through the above technical solutions, the inclined setting of the speed reduction adjustment assembly and the buffering effect of the internal structure enable the blank to remain stable when transitioning from the feeding device to the conveyor chain, reducing the offset or dropping of the blank caused by sudden speed changes or direction changes, and ensuring the continuity and stability of the production line.

[0016] In summary, the utility model has the following beneficial effects:

[0017] 1. Through the cooperation of the driving roller path and the feeding device, the blank can enter the rolling area smoothly and continuously, avoiding the pauses and accumulations that may occur during manual feeding. The continuous feeding method ensures the smoothness of the production line, thereby improving the overall production efficiency. The buffer receiving table can form a buffer zone between the feeding assembly and the feeding device, effectively alleviating the problem of material accumulation caused by the mismatch between the feeding speed and the production speed. At the same time, the pusher electric cylinder ensures that the blank can enter the next process orderly and accurately.

[0018] 2. By driving the material blocking roller to rotate through the servo motor, the blanks are pushed to the discharge port one by one, reducing the production interruption caused by poor feeding. The close cooperation among the feeding assembly, the buffer receiving table and the driving roller path realizes the seamless connection of the blank from feeding to entering the rolling process.

[0019] 3. The first buffer spring can absorb and disperse the impact force, reduce the direct impact of the blank on the bearing plate and the entire system, extend its service life, and reduce the noise and vibration generated by the impact, enabling the blank to smoothly transition from the feeding assembly to the driving roller path. The pusher electric cylinder ensures that the blank can enter the rolling process at a predetermined speed and in a predetermined order, improving the continuity and efficiency of the production line.

[0020] 4. The inclined setting of the slow-speed adjustment assembly and the buffering effect of its internal structure enable the blank to remain stable when transitioning from the feeding device to the conveyor chain, reducing the offset or dropping of the blank caused by sudden speed changes or direction changes, and ensuring the continuity and stability of the production line.

[0027] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments.

[0028] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the limitations of the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the drawings.

[0029] A rolling feeding mechanism of a cross wedge rolling mill, as Figures 1-5 shown, includes a bearing table 5, a loading component 1, a buffer receiving table 2, a driving roller path 3 and a feeding device 4. The loading component 1, the buffer receiving table 2 and the feeding device 4 are installed on the bearing table 5. The buffer receiving table 2 is connected to the feeding device 4 through the driving roller path 3. The loading component 1 is located above the buffer receiving table 2. A pushing cylinder is provided on one side of the buffer receiving table 2 away from the driving roller path 3. The body of the pushing cylinder is located on the side of the buffer receiving table 2 where the driving roller path 3 is not installed and is supported by a support on the bearing table 5. The pushing end passes through the side wall of the buffer receiving table 2 to push materials inside the buffer receiving table 2. One end of the driving roller path 3 is fixedly installed on the buffer receiving table 2. The driving roller path 3 is driven by a roller path motor to roll. The driving roller path 3 is lapped on the feeding device 4 through a lapping plate 6. One end of the driving roller path 3 is installed on the buffer receiving table 2 and the other end is supported by a leg on the bearing table 5, showing an inclined setting. The buffer receiving table 2, the driving roller path 3 and the feeding device 4 are arranged from high to low in sequence and are connected to the feeding device 4 through the lapping plate 6, enabling the camshaft blank to perfectly roll into the feeding device 4. The buffer receiving table 2 effectively alleviates the possible material impact during the loading process, making the materials more stable during the transmission process. At the same time, the inclined setting of the driving roller path 3 combined with the drive of the roller path motor can ensure that the materials move along the established path at a stable speed and posture. By controlling the pushing action of the pushing cylinder, it can ensure that the materials are pushed onto the driving roller path 3 at the appropriate time point, further ensuring the continuity and stability of the material transmission.

[0030] The feeding component 1 includes an outer housing 11, a servo motor 12, a material blocking roller 13 and a feeding port 14. The material blocking roller 13 is installed inside the outer housing 11. The material blocking roller 13 is externally connected to the servo motor 12. The outer housing 11 is provided with a feeding port 14. The feeding port 14 is located on the side wall of the outer housing 11 above the material blocking roller 13. The outer housing 11 is installed on the bearing table 5 through support legs. The bottom of the outer housing 11 is provided with a discharge port. The support legs are preferably six, symmetrically arranged in groups of three, which improves the feeding stability. The feeding port 14 is externally connected to a processing section of the blank of the camshaft. The feeding port 14 is located above the material blocking roller 13 and is opened at the short side of the outer housing 11. The short side of the outer housing 11 faces the conveying roller path, ensuring that the blank of the camshaft is in a vertical state when feeding, which is beneficial to the smooth entry of the blank into the V-shaped gap of the material blocking roller 13, and also reduces problems such as material jamming and dropping caused by incorrect postures, improving the feeding efficiency and reliability. The material blocking roller 13 is driven to rotate by the servo motor 12. The outer surface of the material blocking roller 13 is circularly arrayed with baffles. After the blank of the camshaft is fed, it falls into the V-shaped gap of the baffles on the surface of the material blocking roller 13 for single-rotation feeding, avoiding the accumulation and collision between blanks, and ensuring that each blank can enter the next processing section in sequence and individually, greatly improving the production efficiency.

[0031] The buffer receiving table 2 includes a bearing plate 21, a first buffer spring 22 and a receiving box 23. The bearing plate 21 is movably installed in the bearing box through the first buffer spring 22. One side of the bearing box is connected to the transmission roller path 3. The other side of the bearing box is movably installed with a pushing electric cylinder. A plurality of first buffer springs 22 are installed between the bearing plate 21 and the bearing box. When the material enters the bearing plate 21, the plurality of first buffer springs 22 can effectively absorb and disperse the impact force, reducing the direct impact of the material on the bearing plate 21 and the entire system, and improving the overall service life. One side of the receiving box 23 is provided with a through hole communicating with the transmission roller path 3. The height of the bearing plate 21 supported by the plurality of first buffer springs 22 is higher than the through hole. After being pressed down by the feeding force, it is convenient for the pushing electric cylinder to push it out. The buffer receiving table 2 serves as a transition area between the feeding component 1 and the transmission roller path 3. Through its buffering and shock-absorbing effects, the blank can be smoothly transitioned from the feeding component 1 to the transmission roller path 3, ensuring that the blank maintains the correct posture and speed before entering the rolling process.

[0032] The feeding device 4 includes a support shell 41, a speed reduction adjustment assembly 42, a conveyor chain 43 and a drive motor 44. The transmission roller path 3 is lapped on one side of the support shell 41. The speed reduction adjustment assembly 42 is movably installed on the other side of the support shell 41. The conveyor chain 43 is installed at the bottom of the support shell 41. The conveyor chain 43 is externally connected to the drive motor 44. The speed reduction adjustment assembly 42 is inclined. The speed reduction adjustment assembly 42 inclines towards the bottom of the support shell 41. The speed reduction adjustment assembly 42 includes a speed reduction plate 421, a second buffer spring 422 and a damper 423. The speed reduction plate 421 is inclined and installed on the support shell 41. Both the second buffer spring 422 and the damper 423 are located between the speed reduction plate 421 and the support shell 41. A plurality of second buffer springs 422 and a plurality of dampers 423 are installed between the speed reduction plate 421 and the support shell 41. When the camshaft is conveyed by the transmission roller path 3 to the feeding device 4, it first contacts the speed reduction adjustment assembly 42. The force on its speed reduction plate 421 is dispersed and impacted, significantly reducing the possible damage or deformation of the camshaft caused by direct impact, and adjusting it horizontally to the conveyor chain 43 smoothly, reducing the subsequent processing problems that may be caused by the incorrect posture of the camshaft. The camshaft has been well buffered and its posture adjusted before entering the conveyor chain 43. Therefore, the subsequent processing process can proceed more smoothly, reducing the downtime and manual intervention caused by camshaft problems, thereby improving the overall production efficiency. The connection end of the speed reduction plate 421 and the support shell 41 is connected by a pin and the angle can be adjusted. By adjusting the angle of the speed reduction plate 421, the stiffness of the second buffer spring 422 and the damping coefficient of the damper 423, the precise control of the speed of the blank entering the conveyor chain 43 can be achieved, reducing the impact and vibration generated during the conveying process of the blank on the transmission roller path 3.

[0033] Working principle: The camshaft comes out from the outlet of the processing equipment of the previous program, vertically enters the outer housing 11 from the feeding port 14, and is driven by the baffle roller 13 for single blanking. The camshaft drops to the bearing plate 21 and is shock-absorbed and buffered by the first buffer spring 22, and then pushes the electric cylinder to operate and push it into the transmission roller path 3. The camshaft moves along with the transmission roller path 3 until it reaches the feeding device 4. Due to the existence of the overlapping plate 6, it is guided to the speed reduction adjustment assembly 42, changing the vertical drop of the camshaft to a horizontal orientation, and is fed by the drive of the conveyor chain.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
