Description

Technical Field

[0001] This utility model relates to a roll forging machine, specifically a direct-drive integrated roll forging machine, belonging to the field of roll forging technology. Background Technology

[0002] Roll forging is a plastic forming process of rotary forging. It uses a pair of counter-rotating fan-shaped dies to continuously and locally compress the material, causing it to stretch and deform along its length. It belongs to the rotary compression forming technology.

[0003] Patent No. CN201020591055.1 discloses a roll forging machine, the structure of which includes an integral base, a roll forging machine part and a robot arm part arranged on the integral base. The robot arm part includes a transverse movement mechanism, a longitudinal clamping and compensation mechanism, a clamp rotation mechanism and an external hydraulic control system. The robot arm part is connected to the roll forging machine part through a swing arm.

[0004] The roll forging machine disclosed in the aforementioned patent, as well as other roll forging machines in the prior art, generally suffer from the following technical problems: 1. The robotic arm is mounted on a separate housing, which is connected to the forging machine via a linkage structure. The linkage structure has a wear ring and a long power transmission path, making it prone to asynchronous and inaccurate feeding movements between the robotic arm and the machine, affecting forging quality and die life.

[0005] 2. The housing is equipped with three large swing arms, a large shaft, and a guide rail. The swinging motion of the swing arms is used to simulate the action of a robotic arm for feeding, or an electronic cam is used to simulate the action of a robotic arm for feeding. The action mechanism is complex, and problems such as loosening and loss of parallelism are prone to occur during long-term use, affecting the accuracy of the robotic arm's movement and even causing accidents. In addition, the large size of the housing results in a large footprint.

[0006] 3. The feeding stroke of the robotic arm is not easy to adjust flexibly as needed. Adjustment often requires cumbersome mechanical disassembly and assembly or modification of complex program parameters, making it difficult to quickly adapt to different processes or multi-variety production.

[0007] In summary, the existing technology obviously has inconveniences and defects in practical use. Therefore, it is necessary to propose a new type of direct-drive integrated roll forging machine to solve the bottlenecks in the existing technology. Utility Model Content

[0008] This utility model addresses the shortcomings of the prior art by providing a direct-connection integrated roll forging machine. The main unit is directly connected to the robot arm, ensuring the synchronization and precision of the feeding action with the main unit's action, improving the reliability of the feeding mechanism, and solving the problems of complex adjustment, insufficient flexibility, and large footprint.

[0009] To solve the above technical problems, the present invention adopts the following technical solution: The direct-drive integrated roll forging machine includes a main unit and a feeding mechanism. The main unit is directly connected to the robot arm to ensure precise transmission. It replaces the traditional roll forging machine robot arm that uses a multi-bar mechanism or electronic cam to simulate its movements, saving three large swing arms, one large shaft, one bar rail and connecting rod. The feeding mechanism includes a longitudinal trolley and a transverse trolley arranged vertically in the direction of movement; the longitudinal trolley is slidably mounted on the support base and is directly connected to the swing arm of the main unit, which drives the longitudinal trolley to move back and forth; the transverse trolley is slidably mounted above the longitudinal trolley, and a feeding shaft is installed inside the transverse trolley, with a robotic arm installed on the end of the feeding shaft near the main unit.

[0010] Furthermore, the main unit is fixed above the common base, and the feeding mechanism is fixed above the common base via its bottom support.

[0011] Furthermore, the main unit includes two rollers arranged in parallel and rotating synchronously, with a turntable installed on one end of the upper roller, and the turntable connected to the swing arm.

[0012] Furthermore, a roller is installed inside the lower end of the swing arm, and the swing arm directly drives the robot arm to move.

[0013] Furthermore, the longitudinal transfer vehicle has an overall L-shaped structure, and the bottom of the longitudinal transfer vehicle is mounted on the longitudinal transfer guide rail via a slider. The longitudinal transfer guide rail is fixed to the upper surface of the support base.

[0014] Furthermore, the longitudinal transfer car is connected to the lower end of the swing arm via an upper transmission seat and a lower transmission seat. The lower transmission seat is fixed to the surface of the longitudinal transfer car, and the upper transmission seat has a receiving groove inside for the lower end of the swing arm and the roller to enter.

[0015] Furthermore, the upper and lower transmission seats are tightly engaged by rectangular teeth and fixedly connected by bolts; the lower transmission seat has rows of screw holes, and the relative position between the upper and lower transmission seats can be adjusted.

[0016] Furthermore, two parallel transverse guide rails are fixedly installed at the bottom of the transverse moving vehicle. The transverse guide rails are slidably mounted on the slider, and the slider is fixed to the upper surface of the longitudinal moving vehicle.

[0017] Furthermore, a lead screw is installed between the two transverse guide rails and is arranged parallel to them. The lead screw is rotatably mounted on the longitudinal traverse carriage, and a lead screw nut is installed on the lead screw. The lead screw nut is fixed to the bottom of the transverse traverse carriage, and the end of the lead screw is connected to a servo motor.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: The main unit is directly connected to the robot arm to ensure precise transmission, replacing the traditional robot arm of the rolling mill that uses a multi-bar mechanism or electronic cam to simulate its movements. This eliminates the need for three large swing arms, a large shaft, a bar rail, and connecting rods. The structure is simple and reasonable, saving materials and reducing the floor space. It also ensures stability and reliability during long-term use, making the coordination between the moving robot arm and the roll accurate and timely, and the movement error-free.

[0019] By directly converting the rotation of the rolls into the linear reciprocating motion of the longitudinal transfer carriage through the swing arm, a purely mechanical rigid drive is achieved, ensuring absolute synchronization between the feeding action and the rotation of the rolls. This allows the workpiece to be accurately and timely fed into the optimal position of the die slot, significantly improving the dimensional consistency and surface quality of the forgings.

[0020] The feeding stroke and lateral position can be easily adjusted, enabling a single machine to adapt more quickly to complex roll forging processes with multiple varieties and multiple passes, and shortening the changeover adjustment time. The upper and lower transmission seats are connected by rectangular teeth and are equipped with rows of screw holes, allowing for quick adjustment of their relative positions and easy adjustment of the longitudinal feeding stroke. The lateral position is achieved by a servo motor driving a lead screw.

[0021] The overall structure is compact and reasonable, saving space.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0026] like Figures 3-8 As shown in the figure, this utility model provides a direct-connection integrated roll forging machine, including a main unit 3 and a feeding mechanism. The main unit 3 is fixedly connected to the common base 1, and the feeding mechanism is fixedly connected to the common base 1 through the support seat 2 at its bottom.

[0027] The feeding mechanism includes a longitudinal trolley 4 and a transverse trolley 5, which are arranged vertically in the direction of movement. The longitudinal trolley 4 is slidably mounted on the support base 2 and is directly connected to the swing arm 34 of the main unit 3. The swing arm 34 drives the longitudinal trolley 4 to move back and forth. The transverse trolley 5 is slidably mounted above the longitudinal trolley 4. The transverse trolley 5 is equipped with a feeding shaft 6 that can be adjusted up, down, left, and right. A robotic arm 7 is mounted on the end of the feeding shaft 6 near the main unit 3.

[0028] The main unit 3 includes two rollers 31 arranged in parallel and rotating synchronously. One end of each roller 31 is located inside a reduction gearbox 32, and a motor is installed on the reduction gearbox 32 to provide power for the rotation of the rollers 31.

[0029] A turntable 33 is installed on the end of the upper roller 31 away from the gearbox 32. The turntable 33 is connected to the swing arm 34, which is installed on the end of the rotating shaft 35. The continuous rotational motion of the roller 31 can be converted into the reciprocating swing motion of the swing arm 34 by the turntable 33.

[0030] A roller 36 is installed inside the lower end of the swing arm 34. The roller 36 can change sliding friction into rolling friction, making the reciprocating swing process smoother and the operation more stable.

[0031] The longitudinal moving car 4 has an overall L-shaped structure. The bottom of the longitudinal moving car 4 is mounted on the longitudinal moving guide rail 43 by a slider. The longitudinal moving guide rail 43 is fixed to the upper surface of the support base 2. Preferably, there are three longitudinal moving guide rails 43, which are arranged in parallel.

[0032] The longitudinal transfer carriage 4 is connected to the lower end of the swing arm 34 via the upper transmission seat 41 and the lower transmission seat 42. The lower transmission seat 42 is fixed to the surface of the longitudinal transfer carriage 4. The upper transmission seat 41 has a receiving groove inside for the lower end of the swing arm 34 and the roller 36 to enter.

[0033] The upper transmission seat 41 and the lower transmission seat 42 are tightly engaged by rectangular teeth and fixedly connected by bolts. The lower transmission seat 42 has rows of screw holes, and the relative position between the upper transmission seat 41 and the lower transmission seat 42 can be flexibly adjusted, thereby adjusting the travel of the longitudinal traverse vehicle 4.

[0034] The bottom of the transverse moving vehicle 5 is fixedly equipped with two parallel transverse moving guide rails 51, which are slidably mounted on the slider, and the slider is fixed to the upper surface of the longitudinal moving vehicle 4.

[0035] A lead screw 52 is installed between the two transverse guide rails 51 and is arranged parallel to them. The lead screw 52 is rotatably mounted on the longitudinal carriage 4. A lead screw nut is installed on the lead screw 52 and is fixed to the bottom of the transverse carriage 5. The end of the lead screw 52 is connected to the servo motor 53. The servo motor 53 provides power for the movement of the transverse carriage 5 along the transverse guide rails 51 by driving the lead screw 52 to rotate.

[0036] The specific working principle of this utility model is as follows: First, the robotic arm 7 clamps the heated billet in the initial position, and the transverse carriage 5 adjusts its lateral position according to the process requirements. The motor of the main unit 3 starts, the roll 31 rotates, and the swing arm 34 swings. The swing arm 34 pulls the longitudinal carriage 4, thereby driving the entire transverse carriage 5, the feeding shaft 6, and the robotic arm 7 to clamp the workpiece and feed it precisely and synchronously into the groove of the roll 31. The workpiece enters between the rotating rolls 31, is bitten in under the action of friction, and completes one round of plastic deformation. After the swing arm 34 swings to the limit position, it begins to swing back, directly pushing the longitudinal carriage 4 and the robotic arm 7 to exit to the starting position. During or after the return, the servo motor 53 drives the transverse carriage 5 to move laterally to the position corresponding to the next groove. Then the next round of feeding and rolling is carried out until all forging passes are completed.

The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
