Description

Technical Field

[0001] This invention relates to the field of roll forging, and in particular to a flexible logistics mechanism for a large roll forging machine. Background Technology

[0002] The robotic arm structure for small and medium-sized roll forging mills mainly consists of a clamping carriage and a transverse conveying mechanism. The clamping carriage is equipped with clamps to hold the roll forgings; it is mounted on the transverse conveying mechanism via a clamping carriage frame and can move along the rolling direction. The clamping carriage and the transverse conveying mechanism move laterally together under the drive of hydraulic cylinders, thereby transferring the rolled roll forgings from one station to the next. The clamping carriage frame is supported on the guide rails of the transverse conveying mechanism by rollers and rolling bearings that roll along the rolling direction. Buffers are fixed at both ends of the clamping carriage to reduce the strong impact when the carriage reaches the end.

[0003] The main body of the lateral conveying mechanism is a closed box-shaped welded structure lateral movement and traversing mechanism base. Two guide rails for the clamping carriage are fixed to the sides of the base, and the clamping carriage is suspended on these two guide rails. Lateral movement is driven by a hydraulic cylinder hinged between the front end of the lateral movement sleeve of the lateral movement and traversing mechanism base and the rear support of the guide tube. The lateral movement and traversing mechanism base's lateral movement sleeve moves along the guide tube installed between the two supports. Two sets of support rollers are located at the lower ends of both ends of the lateral conveying mechanism; these rollers roll along the guide rails during lateral movement.

[0004] The existing robotic gripper cart has two guide rails fixed to the sides of the lateral movement mechanism base, which is welded from a closed box body, and the gripper cart is suspended on these two guide rails. Due to its suspended design, the structure has inherent defects in strength and rigidity, making it difficult to meet the requirements of large roll forgings on current large roll forging machines.

[0005] The logistics and transfer of large roll forgings place higher demands on robotic arms, as the robotic arm solutions for small and medium-sized roll forging machines are no longer sufficient for the requirements of large roll forging machines. For large roll forging machines, the forged parts are heavy and long; furthermore, the forming force and torque required during the forming process are significant. Therefore, the robotic arm must possess greater strength and a stronger structure. For example, using the same clamping and suspension design method as for small and medium-sized roll forging machine robotic arms, the robotic arm would need to be much larger to meet the needs of large roll forging machine robotic arms. While theoretically meeting the mechanical performance requirements with a larger robotic arm, besides significantly increasing manufacturing costs, it also contradicts the energy-saving goals of new processes. The biggest problem is that due to the excessive size of the robotic arm, firstly, the space for roll forging transfer and manufacturing is compressed, and secondly, the existing transfer and manufacturing space is simply insufficient to accommodate the operation of such a large robotic arm. Summary of the Invention

[0006] The purpose of this invention is to overcome the defects in the existing technology and provide a flexible logistics mechanism for large roll forging machines. The mechanism adopts a structure in which double guide rails are placed horizontally on the base of the transverse mechanism, and the clamping carriage is located above the base of the transverse mechanism. The structure has good stability and high strength, and is suitable for clamping large roll forgings. This solves the technical problem that the existing clamping carriage is designed with guide rail suspension, which has low strength and poor stability and is not suitable for clamping, transferring and flipping large roll forgings.

[0007] The technical solution adopted to achieve the purpose of this invention is: A flexible logistics mechanism for a large roll forging mill includes a clamping carriage, a traversing mechanism, and a tilting platform. The clamping carriage is arranged on the base of the traversing mechanism and can move linearly along the length of the traversing mechanism base. The linear movement direction of the clamping carriage is perpendicular to the lateral movement direction of the traversing mechanism base. The tilting platform and the traversing mechanism are located on opposite sides of the roller mechanism of the roll forging mill in the radial direction. A lifting device is provided on the traversing mechanism base near the tilting platform for rolling support of the roll forging during rolling and conveying to the tilting platform. The tilting platform is used to cooperate with the clamping carriage to tilt the roll forging.

[0008] The lifting device includes a support roller and a support roller lifting drive mechanism for controlling the lifting and lowering of the support roller. The axial direction of the support roller is parallel to the lateral movement direction of the base of the lateral movement mechanism.

[0009] The bottom of the clamping vehicle engages with two guide rails on the upper end of the base of the transverse mechanism, and moves linearly along the guide rails; there are two guide rails, which are arranged separately along the width of the guide rails.

[0010] The clamping vehicle has four rollers installed at the bottom of the vehicle, and the circumferential surfaces of the four rollers roll in cooperation with the side surface of the guide rail.

[0011] A buffer is fixed at the rear end of the clamping vehicle to the base of the lateral movement mechanism to absorb the impact energy when the clamping vehicle reaches the end.

[0012] The flipping platform includes a frame and a horizontally arranged and liftable receiving plate arranged on the frame. The receiving plate is driven to move horizontally and vertically, and the horizontal movement direction of the receiving plate is perpendicular to the lateral movement direction of the base of the transverse mechanism.

[0013] The flipping platform includes a lifting seat arranged inside the frame. The lifting seat is located close to the clamping vehicle. The receiving plate is arranged on the lifting seat and moves horizontally at the upper end of the lifting seat and rises and falls with the lifting seat.

[0014] The upper end of the frame is provided with a rotating seat above the receiving plate and away from the clamping car, and a positioning groove is formed on one side of the rotating seat to match the shape of the end of the roll forging.

[0015] The bottom of the lifting seat is connected to a lifting drive mechanism, and the rear end of the receiving plate is connected to a receiving plate moving drive mechanism.

[0016] The roll forging limiting mechanism located at the upper end of the frame includes two limiting plates with adjustable relative distance, spaced apart along the width of the frame.

[0017] This invention arranges two tracks for the clamping car on the top surface of a transverse movement mechanism base welded into a closed box shape, making the clamping car's operation a non-suspended structure. It is supported by the transverse movement mechanism base and can move laterally to switch work positions, driving the roll forging to move for rolling. It is also equipped with a flipping platform for the roll forging to flip and cooperate, which is suitable for large roll forgings and economic requirements. It is beneficial to significantly improve the weight and quality of roll forgings and reduce costs.

[0018] The present invention provides a lifting device at the front end of the base of the transverse mechanism and a flipping platform for flipping the roll forging. The two work together to transfer and flip the roll forging, which greatly reduces the length of the clamp holding the roll forging, reduces the blanking weight, increases the material utilization rate by 5% to 10%, and also reduces the required heating energy.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0023] like Figures 1 to 4As shown, the flexible logistics mechanism for a large roll forging machine according to an embodiment of the present invention includes a clamping carriage 3, a transverse movement mechanism, and a tilting platform 400. The clamping carriage 3 is arranged on the transverse movement mechanism base 200 and can move linearly along the length direction of the transverse movement mechanism base 200. Figure 1 (Moves left and right in the middle), the linear movement direction of the clamping vehicle 3 and the lateral movement direction of the transverse mechanism base 200 (Moves left and right in the middle), Figure 1 The tilting platform 400 and the transverse mechanism are located on opposite sides of the roller mechanism 110 of the roll forging mill 100 in the radial direction (moving vertically). The transverse mechanism base 200 is positioned near the tilting platform 400 on one side. Figure 1 A lifting device 4 is provided on the right side of the roll forging 500, which is used to roll and support the roll forging 500 during rolling and conveying to the tilting platform 400. The tilting platform 400 is used to cooperate with the clamping carriage 3 to tilt the roll forging so that the roll forging 500 can be rolled in the second station. For example, when the roll mechanism 110 of the roll forging mill 100 rolls the roll forging 500 in the first station, the clamping carriage 3 is moved backward by the rolling force. Figure 1 (Moving to the left), the lifting device 4 lifts the rolling support roll forging. After the rolling at the first station is completed, the clamping car moves laterally to support the roll forging. When the roll forging 500 is sent to the flipping platform 400 laterally, the roll forging 500 rolls and supports the roll forging during the process of being transported to the flipping platform 400. The flipping platform 400 is used to cooperate with the clamping car 3 to flip the roll forging when the clamping car rotates the roll forging, so that the roll forging machine can roll the roll forging at the second station.

[0024] In the above embodiments, the lateral movement mechanism further includes a lateral movement drive mechanism 210 for controlling the lateral movement of the lateral movement mechanism base 200. The lateral movement drive mechanism 210 can be driven by a hydraulic cylinder to control the movement of the lateral movement mechanism base 200 and the clamping carriage 3 on it.

[0025] In the above embodiment, the clamping car 3 is provided with a clamping flipping mechanism on the side and a flippable clamp 2 is provided at the front end. The clamping flipping mechanism controls the clamp 2 to flip, which can realize the flipping of the clamp 2 and the roll forging 500 it holds together, so that the roll forging 500 rolled in the first station can be flipped so that the roller mechanism 110 of the roll forging machine 100 can roll the roll forging 500 in the second station.

[0026] The clamp flipping mechanism includes a bracket 11 and a flipping drive mechanism 10 hinged between the bracket 11 and the clamping vehicle 3. The flipping drive mechanism 10 is a hydraulic cylinder or a pneumatic cylinder.

[0027] In one embodiment, the lifting device 4 includes a support roller 41 and a support roller lifting drive mechanism for controlling the lifting and lowering of the support roller. The axial direction of the support roller is parallel to the lateral movement direction of the transverse mechanism base. The support roller lifting drive mechanism can be a hydraulic cylinder or a pneumatic cylinder, etc., and is mounted on the side of the transverse mechanism base 200 via a bracket. Figure 2 The left side of the middle.

[0028] In one embodiment, the bottom of the clamping carriage 3 engages with two guide rails 1 at the upper end of the base of the lateral movement mechanism, and moves linearly along the guide rails 1; the guide rails 1 are two rails, arranged separately along the width direction of the guide rails, please refer to [link to relevant documentation]. Figure 2 , 3 As shown.

[0029] In one embodiment, the bottom of the clamping cart 3 is located on the frame 32. Four rollers 31 are installed at the bottom of the frame. The circumferential surfaces of the four rollers 31 roll in contact with the outer surface of the guide rail. When the clamping cart is driven or subjected to external force, it can move linearly along the guide rail 1. The guide rail can be a U-shaped guide rail with the open sides facing each other. The rollers 31 cooperate with the outer side of the guide rail. An inner roller is also provided in the U-shaped groove on the inner side. Its axis is perpendicular to the axis of the rollers 31. The wheel surface cooperates with the upper and lower ends of the U-shaped groove.

[0030] In one embodiment, a buffer 5 is fixed at the rear end of the clamping vehicle on the base of the lateral movement mechanism. The buffer can be a rubber block, a spring, or other buffer mechanism. There are two buffers, which are arranged opposite each other in the space inside the guide rail and fixed to the inner side of the guide rail by a bracket. They are used to absorb the impact energy when the clamping vehicle moves to the end.

[0031] In one embodiment, the flipping platform 400 includes a frame 6 and a horizontally arranged receiving plate 7 arranged on the frame. The receiving plate is driven to move horizontally and vertically in a linear fashion. The horizontal movement direction of the receiving plate is perpendicular to the lateral movement direction of the transverse mechanism base 200. It is used to receive the roll forging 500 when the clamping machine needs to flip the roll forging 500 and attach the roll forging 500 to the flipping platform.

[0032] In a preferred embodiment, the flipping platform includes a lifting seat 9 arranged inside the frame 6. The lifting seat is located below the receiving plate 7 and close to the clamping car 3. It is used to lift up when the receiving plate extends to receive material to support the lifting of the receiving plate, and to lower down when the receiving plate returns to its initial position after receiving material. The receiving plate 7 is arranged on the lifting seat 9, moves horizontally at the upper end of the lifting seat, and rises and falls with the lifting seat 9.

[0033] To position or limit the roll forging 500 during flipping, a rotating seat 8 is arranged at the upper end of the frame above the receiving plate and away from the clamping car. One side of the rotating seat forms a positioning groove 81 that matches the shape of the end of the roll forging. When the roll forging 500 is flipped, the front end of the roll forging 500 extends into the positioning groove 81. The rear end of the rotating seat is connected to a rotating shaft, which is rotatably mounted above the frame.

[0034] In some specific embodiments, the bottom of the lifting seat is connected to a lifting seat lifting drive mechanism 91, and the rear end of the receiving plate is connected to a receiving plate moving drive mechanism 61. The lifting seat lifting drive mechanism 91 and the receiving plate moving drive mechanism 61 can be linear drive mechanisms such as hydraulic cylinders.

[0035] Furthermore, in order to limit the roll forging 500 when it enters the flipping platform, a roll forging limiting mechanism is arranged at the upper end of the frame. The mechanism includes two limiting plates 12 with adjustable relative distance, which are spaced apart along the width of the frame. The limiting mechanism can be used to guide or limit the roll forging 500 when it enters the flipping platform 400, and to reduce the distance after flipping to limit the roll forging 500 after flipping.

[0036] When the flexible material handling mechanism of the present invention is in operation, the conveyor belt 300 arranged in the workshop delivers the roll forging 500 to a predetermined position. At the same time, the clamping carriage 3 moves along the guide rails 1, which are both located on the base of the transverse mechanism welded to the closed box, to a designated position directly opposite the unloading side of the conveyor belt 300. The clamp 2 clamps the roll forging 500. At this time, the roll forging 500 is located between the two rollers of the roller mechanism 110. The roll forging machine 100 operates to roll the roll forging 500 at the first station. The rolling thrust generated during the rolling process is transmitted to the clamping carriage 3 through the roll forging 500, pushing it to move backward. At the same time, the lifting device 4 located on the base of the transverse mechanism rises and supports the roll forging. The roll forging moves backward with the clamping carriage and rolls on the support roller of the lifting device. After the roll forging 500 is rolled at the first station, one end of the roll forging 500 is clamped by a clamp, and the other end rests on the support roller of the lifting device, realizing the transfer of the large material - the roll forging 500. Finally, the forging and clamping car stop at the set position under the action of the buffer 5.

[0037] Subsequently, under the action of the transverse mechanism, the transverse mechanism base, the clamping carriage located on the transverse mechanism base, and the roll forging 500 move laterally together (moving along the axis of the rollers of the roller mechanism 110) until they are directly opposite the feed port side of the tilting platform; the clamping carriage moves forward in the direction of the tilting platform, clamping the roll forging 500 and rolling it on the support roller of the lifting device. At the same time, the receiving plate 7 on the tilting platform 400 is lifted by the lifting seat 9 and extends in the direction of the clamping carriage, passing between the two rollers 110 arranged vertically on the roll forging machine 100 to receive the roll forging 500.

[0038] When one end of the roll forging 500 rests on the receiving plate 7, the lifting device 4 moves downward to disengage from the roll forging. At the same time, the receiving plate 7 returns with the roll forging 500, and the clamping carriage 3 continues to move synchronously, carrying the roll forging 500 to continue moving towards the rotating seat 8. When the receiving plate 7 reaches the initial position before extension, the clamping carriage 3 continues to move until one end of the roll forging 500 is placed in the positioning groove 81 of the rotating seat 8. At this point, one end of the roll forging 500 is clamped by the clamp 2, and the other end rests in the positioning groove of the rotating seat 8.

[0039] Next, the lifting seat 9 moves downward to the predetermined position, simultaneously lowering the receiving plate 7. The clamping and flipping mechanism 10 on the clamping carriage activates, causing the clamp 2, the roll forging 500, and the rotating seat 8 to rotate simultaneously. The rotation stops after reaching the predetermined position, thus achieving the flipping of the large roll forging. After the roll forging 500 is flipped, the lifting device 4 rises, and the roll forging machine 100 begins operation. The clamp 2 clamps the roll forging 500. During the rolling process, the clamping carriage 3 moves backward along with the roll forging 500 under the rolling thrust generated during rolling, completing the rolling of the roll forging 500 at the second station.
