Description

Technical Field

[0001] This utility model relates to the field of casting production equipment technology, and in particular to a pusher mechanism for removing material from high-temperature castings. Background Technology

[0002] In the production of high-temperature castings (such as certain cylindrical workpieces), the inner top of the workpiece often has a casting head, which needs to be removed by punching at high temperature. This is to avoid difficulties in removing the casting head due to the increased material strength after the workpiece cools. Currently, the typical workflow for this process is as follows: the high-temperature casting is conveyed to the preparation station by a roller conveyor, and then the workpiece is pushed step by step into the punching station of the punching machine by a pushing mechanism set above the roller conveyor. Specifically, after the punching machine completes the punching of one workpiece, the pushing mechanism pushes in the next workpiece to be processed, while pushing the punched workpiece away from the station to the unloading conveyor line.

[0003] In existing technologies, the aforementioned pushing mechanisms generally include a lifting mechanism and a reciprocating linear movement mechanism. Their working logic is as follows: the pushing plate is first driven by the lifting mechanism to descend to a pushing position below the workpiece height, and then the horizontal movement mechanism performs the pushing action. After completing a single push, the pushing plate must rise again to avoid the workpiece behind it, return to the starting position, and then descend again to prepare for the next push. This cyclical rhythm of "horizontal movement, descent, pushing, rising, and returning" requires the inclusion of Z-axis lifting and avoidance actions, resulting in numerous steps throughout the entire work cycle and hindering the improvement of production efficiency.

[0004] Furthermore, due to the inherent height of the workpiece, the lifting mechanism must have a sufficiently large stroke. This results in a large space requirement for its vertical (Z-axis) structural layout, making the overall equipment less compact. Particularly concerning is that the pushing mechanism is constantly exposed to workpieces at temperatures of 500-600℃, creating a very harsh thermal radiation environment. Current technologies often use cylinders as the lifting drive element. However, under continuous high-temperature baking, the cylinder seals are prone to aging and failure, leading to frequent cylinder damage, significantly reducing equipment reliability and lifespan, and resulting in high maintenance costs. Utility Model Content

[0005] In view of this, this utility model proposes a pusher mechanism for removing material from high-temperature castings, aiming to solve the problems of large equipment space occupation, easy damage of core components in high-temperature environment, and low efficiency caused by the use of Z-axis lifting mechanism in the existing pusher mechanism.

[0006] The technical solution of this utility model is implemented as follows: This utility model provides a pusher mechanism for removing material from high-temperature castings, comprising: The transmission unit includes a frame and a conveyor roller conveyor mounted on the frame, the conveyor roller conveyor being used to transmit high-temperature workpieces; A drive unit, located on one side of the frame, includes a linear drive mechanism and a tilting drive mechanism; A pusher assembly is connected to the drive unit; wherein the linear drive mechanism is configured to drive the pusher assembly to reciprocate linearly along the conveying direction of the conveying roller to complete the pushing of the workpiece; the flipping drive mechanism is configured to drive the pusher assembly to rotate around a horizontal axis, so that it switches between a horizontal pushing station and a lifting and avoiding station.

[0007] Based on the above technical solution, preferably, the conveying roller conveyor includes a powered roller conveyor and a non-powered roller conveyor, and the powered roller conveyor and the non-powered roller conveyor are sequentially arranged on the frame along the conveying direction of the high-temperature workpiece.

[0008] Based on the above technical solution, preferably, the push rod assembly includes a rotating shaft and a plurality of push rods. The rotating shaft is horizontally arranged on one side of the frame along the length direction of the frame and is connected to the output end of the flipping drive mechanism. The plurality of push rods are fixedly arranged at intervals along the length direction of the rotating shaft.

[0009] Based on the above technical solution, preferably, the push rod includes a fixed base and a rod body, one end of the rod body is vertically fixed to the rotating shaft through the fixed base, and the side of the rod body used to push the workpiece is provided with a V-groove.

[0010] Based on the above technical solution, preferably, positioning protrusions are fixedly provided on both sides of the V-groove in the horizontal direction.

[0011] Based on the above technical solution, preferably, the linear drive mechanism includes a mounting base, a reduction motor, a gear, and a guide rack. The mounting base is slidably disposed on the side wall of the frame, and its sliding direction is consistent with the length direction of the frame. The guide rack is horizontally fixedly disposed on the side wall of the frame. The reduction motor is fixedly disposed on the mounting base, and the output shaft of the reduction motor is connected to the rack through gear meshing. The tilting drive mechanism is disposed on the mounting base.

[0012] Based on the above technical solution, preferably, the flipping drive mechanism includes a drive motor and a gear set driven by the drive motor. The drive motor is fixedly mounted on the top of the mounting base, the gear set is connected to the rotating shaft, and the mounting base is provided with rotating bearings at intervals. The rotating shaft is rotatably supported in the rotating bearings.

[0013] Based on the above technical solution, preferably, a guide rail assembly is provided between the mounting base and the side wall of the frame; the guide rail assembly includes a slide rail fixedly installed on the side wall of the frame and multiple sets of rollers rotatably installed on the mounting base; the rollers simultaneously make rolling contact with the bottom surface of the slide rail and the top surface of the guide rail rack.

[0014] Based on the above technical solution, preferably, the starting point and ending point of the linear drive mechanism are both provided with limiting members that are fixedly connected to the side wall of the frame.

[0015] Based on the above technical solution, preferably, a safety guard is provided on the frame corresponding to the area above the conveyor roller and the moving area of ​​the pusher rod assembly.

[0016] The present invention has the following advantages over the prior art: By placing the drive unit on one side of the frame, the core transmission components are effectively isolated from the high-temperature workpiece radiation area, solving the problem of easy heat damage to the transmission mechanism under high-temperature environments. By setting a motion scheme for the push rod assembly that uses rotation around a horizontal axis instead of vertical lifting, the originally complex spatial motion is simplified into planar motion, achieving the technical effect of significantly compact equipment structure and significantly improved space utilization. Through the coordinated cooperation of the transmission unit, drive unit, and push rod assembly, the pushing action logic is simplified from the traditional multi-step cycle to a highly efficient composite motion, achieving the technical effect of significantly shortening the single pushing cycle and significantly improving production efficiency.

[0017] By incorporating powered and unpowered roller conveyors on the frame, the problem of seamless transition between continuous conveying and intermittent pushing is resolved. The powered roller conveyor handles the dynamic transfer and initial positioning of the workpiece, while the unpowered roller conveyor serves as a static positioning and buffer platform, ensuring the workpiece is in a stable and precise position before pushing. This eliminates the need for the pusher assembly to handle moving workpieces; it only needs to perform an efficient "flip-push-reset" action after the workpiece has come to a stop on the unpowered roller conveyor. This design simplifies complex synchronous control into sequential control, significantly reducing system control complexity and improving the reliability and rhythm of the entire pushing process.

[0018] By arranging several push rods at fixed intervals along the length of the rotating shaft, when the linear drive mechanism pushes the push rod assembly forward, multiple push rods can act synchronously on multiple workpieces, causing them to advance together by one material position. During the return stroke, the push rod assembly only needs to retreat one material position to start the next round of pushing. This mechanism of "synchronous pushing of multiple workpieces and minimum stroke retraction" transforms the traditional single-piece, long-stroke pushing mode into a production line-style stepping mode, greatly shortening the idle stroke time and thus significantly improving the efficiency of reciprocating motion.

[0019] By utilizing a guide rack as a second guide rail, a dual-track support system composed of the slide rail and the top surface of the guide rack is constructed, allowing the roller to roll in contact with both simultaneously, thereby simplifying the motion mechanism and comprehensively improving its performance. This design not only eliminates the need for a separate linear guide pair, reducing manufacturing costs and assembly complexity, but also effectively resists the overturning torque and lateral force during the material pushing process by enhancing motion constraints, ensuring the smoothness and accuracy of the mounting base's movement. At the same time, its low friction and low inertia characteristics provide a mechanical basis for high-speed reciprocating motion, achieving overall synergistic optimization of equipment rigidity, stability, and operating efficiency.

[0029] like Figure 1 As shown, combined with Figure 2-6 This utility model discloses a pusher mechanism for removing material from a high-temperature casting head. Its core technical solution lies in the structural design of replacing the lifting and lowering by placing the drive unit 2 on the side and flipping the pusher rod 32 assembly 3, which fundamentally solves the technical defects of the traditional solution. The specific implementation method is as follows.

[0030] The high-temperature casting part removal head pusher mechanism disclosed in this embodiment includes a transmission unit 1, a drive unit 2, and a pusher rod assembly 3.

[0031] The transmission unit 1 includes a frame 11 and a conveyor roller 12 mounted on the frame 11. The conveyor roller 12 is used to transport high-temperature workpieces S. In actual use, the two ends of the frame 11 in the transmission direction are connected to a feeding conveyor line and a stamping machine, respectively. The high-temperature castings transported by the feeding conveyor line are transferred to the conveyor roller 12 on the frame 11. The conveyor roller 12 provides a continuous and stable conveying path for the high-temperature workpieces S and provides a reference for the pushing action.

[0032] In this embodiment, the frame 11 adopts a welded steel structure and undergoes rust-proof and heat-resistant treatment to ensure structural stability in high-temperature environments. The conveyor roller conveyor 12 is composed of parallel high-temperature resistant metal rollers, and the roller surface can be sprayed with a heat-resistant coating to extend its service life.

[0033] The drive unit 2 is mounted on one side of the frame 11 and includes a linear drive mechanism 21 and a tilting drive mechanism 22. This side-mounted layout of the two drive mechanisms completely avoids the direct heat radiation zone of the high-temperature workpiece S, preventing damage to the transmission components. The linear drive mechanism 21 drives the pusher rod assembly 3 to move horizontally, while the tilting drive mechanism 22 enables the pusher rod assembly 3 to actively tilt. The two drive mechanisms work together to control the horizontal movement and angle change of the pusher rod 32, replacing the complex lifting and lowering actions of traditional solutions.

[0034] The push rod assembly 3 is connected to the drive unit 2; wherein, the linear drive mechanism 21 is configured to drive the push rod assembly 3 to reciprocate linearly along the conveying direction of the conveying roller 12 to complete the pushing of the workpiece; the flipping drive mechanism 22 is configured to drive the push rod assembly 3 to rotate around a horizontal axis, so that it switches between a horizontal pushing station and a lifting and avoiding station.

[0035] Specifically, the pusher assembly 3 establishes a transmission connection with the drive unit 2, and its movement process follows a simplified logic of "flip-push-lift-reset". When the workpiece reaches the predetermined station, the flip drive mechanism 22 first rotates the pusher 32 to the horizontal pushing station; then the linear drive mechanism 21 pushes the pusher 32 forward, accurately pushing the workpiece into the press table; after pushing, the pusher assembly 3 immediately flips to the lifting and clearance station, while the linear drive mechanism 21 drives the pusher assembly 3 to retract and reset. This movement method replaces the traditional Z-axis lifting and lowering spatial movement with planar motion rotating around the horizontal axis, which not only reduces the height of the equipment, but also simplifies the action cycle from the traditional three steps of "downward-push-upward" to two steps of "flip-push", significantly improving work efficiency.

[0036] By placing the drive unit 2 on one side of the frame 11, the core transmission components are effectively isolated from the radiation area of ​​the high-temperature workpiece S, solving the problem of easy heat damage to the transmission mechanism under high-temperature conditions. By setting a motion scheme of the push rod assembly 3 that uses rotation around a horizontal axis instead of vertical lifting, the originally complex spatial motion is simplified into planar motion, achieving the technical effect of significantly compact equipment structure and significantly improved space utilization. Through the coordinated cooperation of the transmission unit 1, drive unit 2 and push rod assembly 3, the pushing action logic is simplified from the traditional multi-step cycle to a highly efficient composite motion, achieving the technical effect of significantly shortening the single pushing cycle and significantly improving production efficiency.

[0037] In some embodiments, the conveyor roller conveyor 12 includes a powered roller conveyor 121 and a non-powered roller conveyor 122, which are sequentially arranged on the frame 11 along the conveying direction of the high-temperature workpiece S.

[0038] The workpiece is conveyed to the powered roller conveyor section, which is driven by a motor and plays a crucial role in transmission and precise positioning. It actively receives the workpiece and smoothly and controllably transports it to the predetermined pushing station. During this process, the workpiece transitions from the powered roller conveyor 121 to the unpowered roller conveyor section. This section of the roller conveyor itself is unpowered, and its main function is to serve as a temporary storage area and buffer zone for the workpiece, ensuring that the workpiece remains stable while waiting to be pushed.

[0039] Once the workpiece is positioned on the unpowered roller conveyor 122, the pusher assembly 3 begins to move. Under the action of the flipping drive mechanism 22, the pusher 32 is leveled to the horizontal pushing position. Then, the linear drive mechanism 21 drives the entire pusher assembly 3 forward, precisely pushing the workpiece away from the unpowered roller conveyor 122 and into the stamping machine worktable for de-materialization.

[0040] In this embodiment, the core purpose of setting up the powered roller conveyor 121 is to provide controllable power for the step-by-step precise conveying of the high-temperature workpiece S, thereby forming an efficient and reliable collaborative operation cycle with the step-by-step pushing operation of the pusher assembly 3. The technical principle is that the powered roller conveyor 121, as the active transmission section, through precise positioning control of drive sources such as servo motors, can transport the continuously entering high-temperature workpiece S from the loading end in a controlled manner, according to a preset rhythm, one by one and accurately to the designated pushing preparation station, i.e., the unpowered roller conveyor section. This combination of "powered roller conveyor conveying + unpowered roller conveyor positioning" solves the problem of action connection between continuous conveying and intermittent pushing. The powered roller conveyor 121 is responsible for the dynamic transfer and initial positioning of the workpiece, while the unpowered roller conveyor 122 serves as a static positioning and buffer platform, ensuring that the workpiece is in a stable and precise position before pushing. This allows the pusher assembly 3 to perform an efficient "flip-push-reset" action only after the workpiece has come to a stop on the unpowered roller conveyor 122, without having to handle the moving workpiece. This design simplifies complex synchronous control into sequential control, greatly reducing the complexity of system control and improving the reliability and rhythm of the entire feeding process.

[0041] In some embodiments, the pusher assembly 3 includes a rotating shaft 31 and a plurality of pusher rods 32. The rotating shaft 31 is horizontally disposed on one side of the frame 11 along its length and is connected to the output end of the flipping drive mechanism 22. The ingenuity of this side-mounted layout lies in moving the rotating shaft 31, which bears the main transmission function, and its drive mechanism away from directly above the high-temperature workpiece S conveying channel, thus avoiding the most direct heat radiation area. This is the structural basis for achieving the high-temperature resistance of the equipment. At the same time, the horizontally disposed rotating shaft 31 defines a clear flipping axis, simplifying the "lifting" and "flattening" actions of the pusher rods 32 into rotation around a single axis, fundamentally replacing the Z-axis lifting motion that requires a complex guiding structure.

[0042] Several push rods 32 are fixedly arranged at intervals along the length of the rotating shaft 31. When the linear drive mechanism 21 pushes the push rod assembly 3 forward, multiple push rods 32 can act simultaneously on multiple workpieces, causing them to advance together by one material position. During the return stroke, the push rod assembly 3 only needs to retreat one material position to start the next round of pushing. This mechanism of "multi-workpiece synchronous pushing and minimum stroke retraction" transforms the traditional single-piece, long-stroke pushing mode into a production line-style stepping mode, greatly shortening the idle stroke time and thus significantly improving the reciprocating motion efficiency.

[0043] In some embodiments, the push rod 32 includes a fixed base 321 and a rod body 322. One end of the rod body 322 is vertically fixedly connected to the rotating shaft 31 through the fixed base 321. The side of the rod body 322 used for pushing the workpiece is provided with a V-groove 3221.

[0044] Specifically, the push rod 32 is divided into a fixed seat 321 that connects to the rotating shaft 31 and a rod body 322 that directly contacts the workpiece. This split structure facilitates manufacturing, maintenance, and replacement. For example, after the rod body 322 wears out due to prolonged contact with the high-temperature workpiece S, it can be replaced independently without altering the fixed seat 321 and the rotating shaft 31, significantly improving the maintainability and service life of the equipment. A V-groove 3221 is formed on the pushing side of the rod body 322, creating a highly efficient self-centering mechanism. When pushing a cylindrical workpiece, the inclined surface of the V-groove 3221 naturally forms two-point contact with the outer circle of the workpiece, generating a centripetal force during the pushing process. This automatically corrects any minor deviations that may exist in the workpiece, ensuring that it moves accurately along the preset trajectory. This effectively prevents the workpiece from rolling or slipping on the roller conveyor, ensuring that the workpiece ultimately enters the stamping die precisely.

[0045] When a cylindrical workpiece is placed in the V-groove 3221, its main contact surfaces are the two inclined surfaces of the V-groove 3221, which provides stable radial positioning. However, at the opening edge of the V-groove 3221, the workpiece only forms an unstable "line contact" or a very small area of ​​"surface contact" with the groove opening. During high-speed or vibrating pushing processes, this weak constraint can indeed cause the workpiece to experience slight bouncing or rolling, or even slip out of the opening, resulting in radial positioning failure.

[0046] Therefore, in this example, positioning protrusions 3222 are fixedly provided on both sides of the V-groove 3221 in the horizontal direction. The positioning protrusions 3222 extend upward from the edge of the opening of the V-groove 3221, and their inner surfaces form a larger and more reliable contact area with the cylindrical surface of the workpiece. This is equivalent to erecting "guardrails" for the workpiece on both sides of the opening of the V-groove 3221, transforming unstable line contact into stable surface contact, thereby strengthening the radial constraint capability of the V-groove 3221 at the opening. By providing additional and more reliable radial constraint surfaces, it effectively eliminates the positioning uncertainty that may occur at the opening of the V-groove 3221, ensuring that the workpiece has a stable posture and accurate trajectory throughout the entire pushing process.

[0047] In some embodiments, the linear drive mechanism 21 includes a mounting base 211, a reduction motor 212, a gear 213, and a guide rack 214. The mounting base 211 is slidably disposed on the side wall of the frame 11, and its sliding direction is consistent with the length direction of the frame 11. The guide rack 214 is horizontally fixedly disposed on the side wall of the frame 11. The reduction motor 212 is fixedly disposed on the mounting base 211, and the output shaft of the reduction motor 212 is meshed with the guide rack 214 through the gear 213. The flipping drive mechanism 22 is disposed on the mounting base 211.

[0048] This mechanism employs the reaction force principle of "motor drive - gear transmission - rack and pinion fixation": when the geared motor 212 drives the gear 213 to rotate, since the guide rail rack 214 is fixed, the gear 213 will roll along the guide rail rack 214, thereby driving the entire mounting base 211 and its supporting tilting drive mechanism 22 to move along a linear trajectory. This transmission method features high precision and good rigidity, and can meet the stringent positioning accuracy requirements of the push rod assembly 3.

[0049] In some embodiments, the flipping drive mechanism 22 includes a drive motor 221 and a gear set 222 driven by the drive motor 221. The drive motor 221 is fixedly mounted on the top of the mounting base 211. The gear set 222 is connected to the rotating shaft 31 in a transmission manner. Rotary bearings 223 are spaced apart on the mounting base 211. The rotating shaft 31 is rotatably supported in the rotary bearings 223.

[0050] Specifically, the drive motor 221 is securely mounted on top of the mounting base 211. This arrangement makes full use of the upper space of the mounting base 211, keeping the power source away from the transmission plane of the high-temperature workpiece S, while ensuring the compactness and rigidity of the transmission connection between the motor and the gear set 222. As a key transmission medium, the gear set 222 effectively converts the speed and torque output by the motor and accurately transmits them to the rotating shaft 31 of the push rod assembly 3, thereby controlling the push rod 32 to complete a precise flipping action.

[0051] In this embodiment, the gear set 222 includes a drive gear and a transmission gear. The drive gear is fixedly connected to the output shaft of the drive motor 221, and the transmission gear is fixedly connected to the rotating shaft 31. This enables the drive motor 221 to transmit its output torque to the rotating shaft 31 through the gear set 222. As a result, the rotation of the rotating shaft 31 drives multiple push rods 32 to rotate synchronously. In this embodiment, the drive motor 221 is set as a geared motor.

[0052] The rotating bearings 223 spaced apart on the mounting base 211 provide a stable and low-friction rotational support for the rotating shaft 31, ensuring that the rotating shaft 31 can still rotate smoothly and accurately around its axis when bearing the weight of the push rod assembly 3 and the working load.

[0053] In some embodiments, a guide rail assembly 215 is provided between the mounting base 211 and the side wall of the frame 11; the guide rail assembly 215 includes a slide rail 2151 fixedly mounted on the side wall of the frame 11 and a plurality of rollers 2152 rotatably mounted on the mounting base 211; the rollers 2152 simultaneously make rolling contact with the bottom surface of the slide rail 2151 and the top surface of the guide rail rack 214.

[0054] Traditional solutions typically require a separate parallel linear guide pair to ensure motion accuracy. However, this embodiment cleverly utilizes the existing structural component (guide rack 214) as a second guide by having the roller 2152 roll simultaneously on the slide rail 2151 (primarily providing guidance) and the top surface of the guide rack 214 (primarily providing transmission and auxiliary load-bearing functions). This design not only eliminates the need for a separate linear guide pair, simplifying the overall mechanism and reducing manufacturing costs and assembly complexity, but also significantly improves the rigidity and stability of the moving components through dual-track support.

[0055] The dual-track support provides more ideal motion constraints for the mounting base 211. The rolling contact of the rollers 2152 on the two parallel tracks forms a stable, statically determinate support structure, effectively resisting the overturning torque and lateral force generated during the feeding process, preventing the mounting base 211 from jamming or wobbling. This not only ensures the smoothness and accuracy of the linear motion of the push rod assembly 3, but its simplified structure also means smaller moment of inertia and lower frictional resistance, thus providing a mechanical basis for achieving faster and more efficient reciprocating motion.

[0056] In some embodiments, the starting and ending points of the linear drive mechanism 21's travel stroke are both provided with limiting members 216 fixedly connected to the side wall of the frame 11. The limiting member 216 is one or both of a mechanical limit buffer and a limit sensor. Specifically, during high-speed reciprocating motion, if the linear drive mechanism 21 exceeds the preset travel range due to control failure, inertia, or unexpected circumstances, it may cause mechanical collisions, equipment damage, or even safety accidents. The mechanical limit buffer fixed to the side wall of the frame 11 acts as a reliable physical barrier, forming redundant safety protection together with the limit sensor. Even if the limit sensor fails, the mechanical limit buffer can force the movement to stop through mechanical obstruction, minimizing the risk.

[0057] In some embodiments, a safety guard 5 is provided on the frame 11 above the conveyor roller 12 and in the movement area of ​​the pusher rod assembly 3. This safety guard 5 addresses two risks simultaneously: first, it prevents burns caused by personnel coming into contact with high-temperature workpieces S with temperatures as high as 500-600°C; second, it isolates the risk of mechanical injury that may occur during the reciprocating motion of the pusher rod assembly 3.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
