Description

Technical Field

[0001] This utility model relates to the technical field of forging processing equipment, specifically a device for automatically rotating and flipping large forgings between heat treatment or machining processes, and more particularly to a forging rotation and flipping device with precise positioning and 180° flipping functions. Background Technology

[0002] In the forging process, forgings need to be flipped multiple times to ensure uniform processing. Existing flipping equipment has the following drawbacks:

[0003] 1. Insufficient positioning accuracy: Traditional roller conveyor equipment lacks an effective correction mechanism, and forgings are prone to deviation during transport, resulting in misalignment of the flipping axis. This requires repeated manual adjustment of the position, affecting processing accuracy and efficiency.

[0004] 2. Poor flipping stability: When using simple grippers or robotic arms for flipping, heavy forgings are prone to swaying or even falling off due to inertia. Especially for irregularly shaped forgings, existing pneumatic clamping mechanisms cannot provide multi-directional limits, posing a safety hazard.

[0005] 3. Low level of automation: Most equipment requires segmented operation - first positioning, then flipping and then outputting. The process relies on manual intervention or independent equipment connection, which cannot realize a continuous automated process of conveying → positioning → flipping → output. In addition, the 180° flipping angle requires manual monitoring, and consistency is difficult to guarantee.

[0006] The aforementioned defects result in low forging processing efficiency and large quality fluctuations, severely restricting the large-scale production of large forgings (such as wind turbine main shafts and pressure vessel heads). This invention aims to solve these problems. Utility Model Content

[0007] In order to overcome the problems of large positioning deviation, instability during the flipping process, and insufficient automation of the process in the existing technology, this utility model provides a forging rotation and flipping device. Through the technical solution of guide bar block positioning, pneumatic limiter clamping, and chain drive support plate, it achieves the technical effects of millimeter-level positioning of forgings, 180° stable flipping, and fully automated continuous operation.

[0008] The technical solution adopted by this utility model to solve its technical problem is as follows: a forging rotating and flipping device, including a platform and supporting legs below it; roller conveyor frames symmetrically arranged on both sides of the platform, the roller conveyor frames including multiple interconnected rollers and a drive unit for driving the rollers to rotate; a support assembly set on the upper part of the platform, including: two vertically symmetrically arranged support plates, the surface of which is perpendicular to the forging conveying direction; support seats symmetrically fixed to the platform, each support seat having a support wheel set on its top via a bearing, the upper part of the support wheel having a groove and abutting against the support plate; a first drive mechanism for driving the support plates to rotate, the output end of which meshes with a ring power element arranged circumferentially on the support plate via a transmission component; a plate seat symmetrically arranged between the two support plates, each plate seat having multiple support rollers and a second drive mechanism for driving the support rollers to rotate; a forging conveying and positioning mechanism set on one of the plate seats; a pneumatic limiter set on the other plate seat, the actuating end of which can extend and abut against the surface of the forging; an angle limiting part set on the outside of the support plate and a corresponding limiting mating part set on the platform.

[0009] In the aforementioned forging rotating and flipping device, the rollers of the roller conveyor frame are linked by a chain, and the drive unit drives at least one roller through a chain transmission mechanism.

[0010] The forging rotation and flipping device described above includes a forging conveying and positioning mechanism comprising a guide bar and an end stop block arranged along the conveying direction, wherein the guide bar is fixed to the plate base by a vertical support rod.

[0011] In the aforementioned forging rotating and flipping device, the two support plates rotate synchronously through circumferentially distributed rigid connecting rods.

[0012] In the aforementioned forging rotating and flipping device, the second drive mechanism transmits power to the support rollers through a sprocket and chain assembly.

[0013] In the aforementioned forging rotation and flipping device, the pneumatic limiter is a double-acting cylinder, and the bottom of its cylinder body is fixed to the plate base by bolts.

[0014] The forging rotating and flipping device described above has a transversely extending transition support bar on the side of the support plate, and symmetrically arranged supporting rollers on the upper part of the transition support bar.

[0015] In the forging rotating and flipping device described above, the groove depth at the top of the support wheel is greater than the thickness of the support plate, forming an axial constraint structure.

[0016] The beneficial effects of this utility model are:

[0017] 1. Improved Turning Stability: Through the contact constraint between the support wheel groove and the support plate, combined with the multi-directional clamping of the cylinder, the inertial sway and axial movement of the forging during turning are effectively suppressed, especially ensuring the turning safety of heavy / irregular forgings.

[0018] 2. Optimized positioning accuracy: By using the forced correction of guide bars embedded in the groove of the forging, the travel limit of the stop block, and the telescopic positioning of the cylinder, the millimeter-level positioning accuracy of the forging in the conveying and flipping station is achieved, eliminating the manual adjustment process.

[0019] 3. Full-process automation: Based on the PLC controller's response to the angle limit signal, the first drive mechanism starts and stops, the cylinder extends and retracts, and the second drive mechanism turns, realizing continuous automated operation of "conveying → positioning → 180° flipping → output", with a flipping angle consistency of over 99%.

Detailed Implementation

[0025] This embodiment describes in detail a forging rotating and flipping device, such as... Figure 1 As shown, the forging rotating and flipping device mainly consists of a base 1, legs, a support assembly 2, and a roller conveyor frame 3. The base 1 serves as the basic support structure of the entire device, with legs evenly arranged around its perimeter to stably support the base 1 on the ground, ensuring the stability of the device during operation. Roller conveyor frames 3 are symmetrically arranged on both sides of the base 1 for linearly conveying the forging. Multiple rollers are evenly and spaced inside the roller conveyor frame 3. These rollers are interconnected by chains to form an integrated conveying system. One of the rollers is connected to an additionally arranged motor via a chain and sprocket. When the motor starts, the roller is driven to rotate through the chain and sprocket, which in turn drives the other rollers to rotate synchronously, realizing the conveying and driving operation of the rollers on the forging. The forging is placed on the roller and moves along the conveying direction as the roller rotates.

[0026] The support assembly 2 is the core part of this device for realizing the rotation and flipping of the forging. There are two support plates 201, which are arranged vertically and symmetrically on the upper part of the platform 1. The surface of the support plate 201 is perpendicular to the direction of conveying the forging on the platform 1. Multiple connecting rods 202 are evenly and spaced along the circumferential direction between the two support plates 201. The connecting rods 202 are connected to the support plates 201 by bolts, so that the two support plates 201 keep moving synchronously. Support seats 203 are symmetrically arranged at the lower part of the support plate 201. The support seats 203 are connected to the platform 1 by bolts to ensure the stability of the support seats 203. A rotatable support wheel 204 is horizontally placed on the top of the support seat 203 through a bearing. The upper part of the support wheel 204 has a groove to accommodate the support plate 201. The support wheel 204 abuts against the support plate 201. When the support wheel 204 rotates, the friction force drives the support plate 201 to rotate. At the same time, the groove design can prevent the support plate 201 from axially misaligning.

[0027] A chain is arranged along the circumferential direction on one side of the support plate 201. The two ends of the chain are locked and fixed by chain buckles. A first motor 205 is arranged on the upper part of the platform 1. The output end of the first motor 205 is connected to a sprocket by a key. The sprocket cooperates with the chain on the support plate 201. When the first motor 205 is started, it drives the sprocket to rotate. The sprocket drives the support plate 201 to rotate circumferentially under the support of the support wheel 204 through the chain, thereby realizing the rotation of the forging.

[0028] Along the direction of forging conveying, support plates 201 are symmetrically arranged at their upper and lower ends, with plate seats 206 connected to the support plates 201 by bolts. Multiple support rollers 207 are spaced apart on the upper part of the plate seats 206 along the direction of forging conveying, and the support rollers 207 are connected to the plate seats 206 via bearing seats. A second motor 208 is also arranged on the upper part of the plate seats 206. The output end of the second motor 208 is keyed to one end of each support roller 207 with a sprocket. A chain is fitted onto the upper part of the sprocket, enabling the conveying of... Power transmission enables the second motor 208 to drive the support roller 207 to rotate. One of the plate seats 206 is provided with a guide bar 209 on its upper part. Support rods 210 are vertically arranged at both ends of the guide bar 209 and are connected to the plate seat 206. The upper part of the forging has a groove that matches the guide bar 209. When the forging is conveyed on the support roller 207, the guide bar 209 is embedded in the groove of the forging, which corrects and positions the conveying direction of the forging, ensuring that the forging can move accurately along the predetermined direction.

[0029] Another plate base 206 has cylinders 211 symmetrically arranged at both ends on its upper part. The cylinder base of the cylinder 211 is connected to the plate base 206 by bolts. During the forging process, the front end of the cylinder rod of the cylinder 211 extends out and abuts against the surface of the forging, which plays a role in limiting and positioning the forging and preventing the forging from shifting or shaking during the flipping process. One end of the guide bar 209 is also provided with a stop block 212. The stop block 212 is symmetrically arranged on the upper part of the plate base 206 and is connected to it by bolts. The stop block 212 plays a role in limiting the movement of the forging. When the forging moves to contact the stop block 212, it stops moving and ensures that the forging is in the appropriate position for the flipping operation.

[0030] A support bar 213 is also horizontally placed on one side of the support plate 201. The support bar 213 is connected to the support plate 201 by bolts. Support rollers 214 are symmetrically arranged on the upper part of the support bar 213. When the forging is transferred from the roller conveyor 3 to the inside of the support assembly 2, the support rollers 214 support the forging, so that the forging can be smoothly transferred from the roller conveyor 3 to the support assembly 2.

[0031] To ensure that the support plate 201 can only rotate within a 180° range, a limit block 215 is arranged on the outside of the support plate 201. The limit block 215 is connected to the support plate 201 by bolts. A limit seat 216 adapted to the support plate 201 is arranged on the upper part of the platform 1. When the support plate 201 rotates to 180°, the limit block 215 abuts against the limit seat 216, which triggers a stop signal. This signal is transmitted to the PLC control system. The PLC control system controls the first motor 205 to stop running. Then the cylinder 211 begins to retract. After the top of the forging loses the support of the cylinder 211, it falls onto the upper part of the support roller 207. Then, driven by the second motor 208, it leaves the support base 203 assembly along the surface of the support roller 207, completing the entire rotation, flipping and conveying process.

[0032] Operating Instructions: With the device in its initial state, the first motor 205 and the second motor 208 are stopped. The cylinder rod of cylinder 211 is in the retracted position and not in contact with the forging. The motor of the roller conveyor 3 is in standby or low-speed operation. Confirm that the PLC control system is ready and that all sensors (such as the contact sensor between limit block 215 and limit seat 216) are functioning normally. The forging to be flipped is placed on the roller conveyor 3 on one side of the device by external equipment or manually. Start the motor of the roller conveyor 3. The motor drives all rollers to rotate synchronously via chains and sprockets, causing the forging to move linearly along the conveying direction (i.e., towards the support assembly 2). The forging moves forward with the rollers, gradually transitioning from the roller conveyor 3 to the support assembly 2 area. During this transition, one end or bottom of the forging first contacts the support roller 214 on one side of the support plate 201. The support roller 214 supports the forging and... The guiding function ensures that the forging is transferred smoothly from the roller conveyor 3 to the support roller 207 of the support assembly 2. The forging is fully inserted between the two support plates 201 of the support assembly 2 and falls on the symmetrically arranged support rollers 207. The second motor 208 on the support assembly 2 is started. The second motor 208 drives the connected support rollers 207 to rotate through the sprocket and chain at its output end. Then, through chain transmission, all support rollers 207 are driven to rotate synchronously. The rotation direction is set to push the forging to move on the support rollers 207 along the predetermined conveying direction (i.e., from the inlet side to the outlet side). During the conveying process, the pre-set groove on the upper part of the forging engages with the guide bar 209 installed on one of the plate seats 206. The guide bar 209 is embedded in the groove, which forcibly corrects and guides the movement path of the forging, effectively preventing the forging from shifting laterally during the conveying process and ensuring that it travels accurately in a straight line.

[0033] Driven by the support roller 207, the forging continues to move until its end (or designated part) contacts the stop 212 mounted on the plate holder 206. The stop 212 prevents the forging from moving forward, stopping it precisely at the preset flipping position within the support assembly 2. At this point, the forging is located between the two support plates 201, and its center of gravity or flipping axis is substantially aligned with the rotation center of the support plate 201. The signal that the forging has reached the predetermined position (contacting the stop 212) (which can be detected by a position sensor or limit switch, or calculated by the PLC based on time / speed) triggers the following movement. Operation: The cylinder rods of two cylinders 211 arranged on another plate seat 206 extend simultaneously, and their front ends press against a specific surface (usually the side or end face) of the forging. The pressure provided by the cylinders 211 reliably clamps, limits, and axially positions the forging, preventing it from shaking or shifting during subsequent flipping. The first motor 205 starts and drives the sprocket at its output end to rotate. The sprocket drives the chain surrounding the support plate 201 to move. The movement of the chain drives the support plate 201 to rotate through friction. The lower part of the support plate 201 is connected by support wheels 2. 04 (mounted on support 203) provides support. Support wheel 204 rotates under the drive of support plate 201. At the same time, the groove on the top of support wheel 204 constrains support plate 201 to prevent axial movement. The two support plates 201 rotate synchronously through connecting rod 202, thereby driving the forging located between them to rotate (flip over) around the horizontal axis. Support plate 201 (together with forging) continues to rotate. When the rotation angle reaches 180° (i.e., the forging has finished flipping over): the limiting block 215 fixed on the outside of support plate 201 rotates with support plate 201 to the position fixed on the base 1. The limit seat 216 abuts against the limit block 215, and the contact between the limit block 215 and the limit seat 216 generates a stop signal (such as triggering a limit switch). This stop signal is transmitted to the PLC control system. After receiving the 180° rotation completion signal, the PLC control system performs the following actions: immediately controls the first motor 205 to stop running, the support plate 201 stops at the 180° position, controls the cylinder 211 to move, causing its cylinder rod to retract, releasing the clamping limit on the forging, and starts the second motor 208 (the direction is set to the output direction), and the support roller 207 rotates again.

[0034] The forging, now freed from the limit of cylinder 211, falls back onto the surface of support roller 207 under gravity. Driven by support roller 207, the forging, now flipped, moves along the conveying direction (towards the roller conveyor 3 on the other side). The forging moves out of the support assembly 2 area and into the roller conveyor 3 on the other side of the device. The roller conveyor 3 starts, conveying the flipped forging away from the device. Cylinder 211 remains in the retracted state, and support plate 201 remains at the 180° position (or, according to the preset program, PLC controls the first motor 205 to reverse, driving support plate 201 back to the 0° initial position to prepare for the next forging flip). The device returns to a state where it can receive the next forging to be flipped.

[0035] The forging rotation and flipping device in this embodiment achieves automatic feeding, rotation and flipping, and positioning of forgings through the coordinated work of the above-mentioned components, thereby improving production efficiency and ensuring the quality and stability of forging processing.
