Description

Technical Field

[0001] The present invention relates to a punching part processing device, and more specifically, to a multi-stage punching device for a punching part for a shock absorber and a control method thereof. Background Art

[0002] With the rapid development of the automobile industry and the machinery manufacturing industry, shock absorbers, as key components, have increasingly higher requirements for the processing accuracy and production efficiency of stamping parts. Traditional shock absorber stamping parts production mostly uses single-station stamping equipment, and material flow is performed manually or by simple manipulators, which has the following technical bottlenecks:

[0003] Inefficient connection of multiple processes: stamping, cutting and other processes need to be transferred multiple times between different equipment. Frequent positioning leads to increased cumulative errors, affecting product consistency. Especially for special-shaped stamping parts, traditional mechanical grippers are difficult to adapt to complex shapes, which can easily cause workpiece deviation or even damage.

[0004] Insufficient automation: The existing production line relies on manual intervention for material height adjustment, mold alignment and other operations, which not only increases labor costs but also poses safety risks. For example, the unstable height of the material storage rack can easily lead to material retrieval failure, and the manual adjustment response is delayed, affecting the production rhythm.

[0005] Low equipment flexibility: Traditional stamping devices use fixed molds and transfer structures, which are difficult to quickly adapt to the production needs of stamping parts of different specifications. When changing product models, the robot arm path needs to be readjusted or the clamping tool needs to be replaced, resulting in a long production line switching time, which restricts the production needs of multiple varieties and small batches.

[0006] Lack of dynamic control: The existing control methods lack real-time feedback on parameters such as material positioning status and clamping pressure. For example, the contact status between the suction head and the workpiece cannot be sensed during the clamping process, which can easily lead to missed grasping or over-pressure damage to the workpiece, affecting the yield rate.

[0007] In response to the above problems, the industry has tried to optimize by adding multi-station integrated design or improving the clamping mechanism, but there are still defects such as loose layout of processing mechanism, redundant transfer path, insufficient dynamic compensation capability, etc. The multi-stage stamping device of the present invention realizes efficient integration and precise coordination of stamping processes through linear processing production line layout, modular functional component design and intelligent control method, which significantly improves the production flexibility and automation level.

In the process of pushing the material, the feeding mechanism detects the height H1 of the top of the material. If H1>H, it is judged that the current height of the material in the storage rack is too high, and the ejector rod retreats a distance of H1-H, so that the material has a suitable height in the storage rack, and jumps to S3 for further processing. On the contrary, if H1<H, it is judged that the current height of the material in the storage rack is too low, and the ejector rod continues to lift a distance of H-H1, so that the material has a suitable height in the storage rack, and jumps to S3 for further processing;

[0018] S3, the transfer rack moves to the top of the storage rack through the slide rail, and the material-taking cylinder pushes the transfer rack downward, so that the suction head at the bottom of the transfer rack conflicts with the material. At the same time, the pressure sensor in the suction head detects the pressure of each suction head. If the value of the pressure sensor in each suction head is ≠0, it is judged that each suction head is currently in conflict with the material. The control center drives the suction head at the bottom of the transfer rack to absorb the material. At the same time, the transfer rack moves along the slide rail to the discharge platform and places the material on the discharge platform for positioning. Otherwise, it is judged that the current suction heads are not all in conflict with the material on the discharge platform, the device stops and notifies the staff to conduct detection;

[0019] S4. The shape structure of the material to be clamped is set in the clamping mechanism. The clamping mechanism calculates the rotation angle C of the rotating components in each clamping mechanism and the moving distance L of the driving arm when transferring the material according to the shape structure of the material and the distance between the suction head and the processing mechanism.

If so, it is determined that the current processing mechanism has not completed processing, and the clamping mechanism remains in the waiting position and continues to detect. Otherwise, it is determined that there is no material in the current processing mechanism, and the clamping mechanism places the material in the processing mechanism;

[0022] S13, the positioning chassis detects whether the material is placed inside it. If so, it is determined that the current material positioning is completed, and jumps to S21 to perform the forming process of the workpiece. Otherwise, it is determined that the current material positioning is not completed in the processing mechanism, the device suspends processing and notifies the staff for maintenance;

[0023] When the control method is a forming process of a workpiece, the following steps are included: S21, the processing mechanism detects whether the material has completed positioning processing. If so, it is determined that the material positioning is completed, and jumps to S22 for material transfer. Otherwise, it is determined that the current material is not positioned, and the processing mechanism continues to detect;

[0024] S22, the clamping mechanism controls the suction head of the clamping mechanism to move to the material of the previous processing mechanism according to the rotation angle C of the rotating component and the moving distance L of the driving arm calculated in step S4, and at the same time, the suction head grabs the material, and the clamping mechanism grabs the material and moves to the waiting position;

[0025] S23, the next processing mechanism detects whether there is material inside it. If so, it is determined that the current processing mechanism has not completed processing, and the clamping mechanism remains in the waiting position and continues to detect. Otherwise, it is determined that there is no material in the current processing mechanism, and the clamping mechanism places the material in the processing mechanism;

[0026] S24, the positioning mold detects whether the material is placed inside it. If so, it is determined that the current material positioning is completed, and jumps to S25 for stamping and forming the material. Otherwise, it is determined that the current material is not positioned in the processing mechanism, the device suspends processing and notifies the staff for maintenance;

[0027] S25, the driving member in the stamping assembly drives the stamping member to move downward, so that the stamping member conflicts with the positioning die, and stamps the material in the positioning die to form it;

[0028] When the control method is the cutting process of the workpiece, the following steps are included: S31, the processing mechanism detects whether the material has completed the forming process of the workpiece. If so, it is determined that the material stamping and forming process is completed, and jumps to S32 to transfer the material. Otherwise, it is determined that the current material has not completed the stamping and forming process, and the processing mechanism continues to detect;

[0029] S32, the clamping mechanism controls the suction head of the clamping mechanism to move to the material of the previous processing mechanism according to the rotation angle C of the rotating component and the moving distance L of the driving arm calculated in step S4, and at the same time, the suction head grabs the material, and the clamping mechanism grabs the material and moves to the waiting position;

[0030] S33, the next processing mechanism detects whether there is material in its internal book. If so, it is determined that the current processing mechanism has not completed processing, and the clamping mechanism remains in the waiting position and continues to detect. Otherwise, it is determined that there is no material in the current processing mechanism, and the clamping mechanism places the material in the processing mechanism;

[0032] S35, the forming cutter moves toward the placement slot, so that the forming cutter collides with the material in the placement slot and completes cutting of the material in the placement slot.

[0033] By adopting the above technical solution, the beneficial effects are as follows: 1. Through the layout of the linear processing production line, the positioning, forming, cutting and other processes are integrated into the same production line, and the clamping mechanism is used between the processing mechanisms to achieve seamless material flow. The clamping mechanism adopts a rotating component and an adaptive suction head design, combined with the drive arm slide and crawler linkage, which can realize accurate path planning in three-dimensional space after calculating the rotation angle C and the moving distance L, avoiding the complexity of multi-axis adjustment of traditional robotic arms. At the same time, the detachable design of the positioning chassis, positioning mold and placement slot in each processing mechanism ensures that the workpiece is always in a pre-positioned state during the transportation process, eliminating the cumulative error of multiple processes. Compared with traditional split equipment, this structure shortens the processing time of a single piece by more than 30%, and the product size tolerance is controlled within ±0.05mm, which significantly improves the yield rate. Through the integration and precise flow of multiple processes, the production rhythm and product consistency of this device are significantly improved.

[0034] 2. Furthermore, the present application can intelligently manage materials and perform adaptive adjustments to achieve unmanned operation of the entire process. Specifically, the loading mechanism uses a processing plate with multiple storage racks and a piston-cylinder-driven ejector rod, in conjunction with real-time detection and dynamic compensation of the material height H (when H1>H, it retreats to H1-H, and when H1<H, it lifts to H-H1), to ensure that the material in the storage rack is always at the optimal material retrieval height, thereby avoiding material retrieval failures caused by stacking misalignment. The transfer rack suction head has an embedded pressure sensor, which triggers the suction action only when it detects that the pressure values ​​of all suction heads are ≠0, effectively preventing the material from falling off due to weak single-point adsorption. Combined with the in-situ detection logic between processing mechanisms (such as the next station status judgment in steps S12 and S23), a closed-loop control system is formed to achieve full process automation from storage, transportation to processing, reducing the need for manual intervention by more than 90%.

[0035] 3. At the same time, the positioning chassis, positioning mold and forming cutter adopt quick-change detachable connections, which can quickly replace the corresponding tooling for stamping parts of different specifications. Combined with the multi-angle adjustment capability of the suction head shaft in the clamping mechanism, it can adapt to the gripping needs of special-shaped workpieces. The control method automatically calculates the rotation angle C and the drive arm stroke L of the clamping mechanism by presetting the material shape parameters to achieve seamless switching of different product models. Compared with the complex process of traditional production lines that require reprogramming of mechanical paths, the changeover time of this device can be shortened to within 15 minutes. It is particularly suitable for efficient response to small batch orders of multiple varieties, and the equipment utilization rate is increased by 40%.

[0036] 4. In addition, during the processing, this equipment can set up a multi-level detection mechanism inside it: in the positioning processing stage (S13), the positioning chassis is detected to determine whether the material is placed in place; in the molding processing stage (S24), the positioning mold contact sensor is used to confirm the positioning status of the workpiece; in the cutting stage (S34), the placement slot photoelectric detection is used to prevent misoperation. If any abnormality occurs in any link (such as material not in place, abnormal suction head pressure), the control center will immediately suspend the process and trigger an alarm to avoid mold collision or workpiece damage. At the same time, the waiting position residence logic of the clamping mechanism (such as continuous detection in S12 and S23) is linked to the processing mechanism status to ensure accurate matching of the beats between processes. The comprehensive utilization rate of the equipment can reach more than 95%, greatly reducing unplanned downtime losses. BRIEF DESCRIPTION OF THE DRAWINGS

Otherwise, it is determined that there is no material in the current processing mechanism 5, and the clamping mechanism 4 places the material in the processing mechanism 5;

[0073] S34, the placement slot 541 detects whether the material is placed inside it. If so, it is determined that the current material positioning is completed, and jumps to S35 to cut the material. Otherwise, it is determined that the current material is not positioned in the processing mechanism 5, the device suspends processing and notifies the staff for maintenance;

[0074] S35 , the forming cutter 542 moves toward the placement slot 541 , so that the forming cutter 542 contacts the material in the placement slot 541 , and the cutting of the material in the placement slot 541 is completed.

[0075] Through the layout of the linear processing production line 1, the positioning, forming, cutting and other processes are integrated into the same production line, and the clamping mechanism 4 is used between each processing mechanism 5 to achieve seamless material flow. The clamping mechanism 4 adopts the design of the rotating component 42 and the adaptive suction head 432, combined with the linkage of the driving arm 44 slide 423 and the crawler 424, which can realize accurate path planning in three-dimensional space after calculating the rotation angle C and the moving distance L, avoiding the complexity of multi-axis adjustment of traditional robotic arms. At the same time, the detachable design of the positioning chassis 521, the positioning mold 531 and the placement slot 541 in each processing mechanism 5 ensures that the workpiece is always in a pre-positioned state during the transportation process, eliminating the accumulated errors of multiple processes. Compared with traditional split equipment, this structure shortens the processing time of a single piece by more than 30%, and the product size tolerance is controlled within ±0.05mm, which significantly improves the yield rate. Through the integration and precise flow of multiple processes, the production rhythm and product consistency of this device are significantly improved.

[0076] Furthermore, the present application can intelligently manage materials and perform adaptive adjustments to achieve unmanned operation of the entire process. Specifically, the loading mechanism 2 is configured with a processing plate 22 and multiple storage racks 23 and a piston-cylinder-driven ejector rod 26, in conjunction with real-time detection and dynamic compensation of the material height H (retracting to H1-H when H1>H, and lifting to H-H1 when H1<H), to ensure that the material in the storage rack 23 is always at the optimal material extraction height, thereby avoiding material extraction failures caused by stacking misalignment. The transfer rack 252 suction head 432 has an embedded pressure sensor, which triggers the suction action only when the pressure values ​​of all suction heads 432 are detected to be ≠0, effectively preventing the material from falling off due to weak single-point adsorption. Combined with the in-situ detection logic of the processing mechanism 5 (such as the next station status judgment in steps S12 and S23), a closed-loop control system is formed to achieve full process automation from material storage, transportation to processing, and reduce the need for manual intervention by more than 90%.

[0077] At the same time, the positioning chassis 521, the positioning mold 531 and the forming cutter 542 adopt a quick-change detachable connection, which can quickly replace the corresponding tooling for stamping parts 533 of different specifications, combined with the multi-angle adjustment ability of the rotating shaft 431 of the suction head 432 in the clamping mechanism 4, to meet the needs of grabbing special-shaped workpieces. The control method automatically calculates the rotation angle C of the clamping mechanism 4 and the stroke L of the driving arm 44 by presetting the material shape parameters to achieve seamless switching of different product models. Compared with the complex process of reprogramming the mechanical path of the traditional production line, the changeover time of this device can be shortened to within 15 minutes, which is particularly suitable for efficient response to small batch orders of multiple varieties, and the equipment utilization rate is increased by 40%.

[0078] Moreover, during the processing, the equipment can set up a multi-level detection mechanism inside: in the positioning processing stage (S13), the positioning chassis 521 is used to detect whether the material is placed in place; in the molding processing stage (S24), the positioning mold 531 contact sensor is used to confirm the positioning status of the workpiece; in the cutting stage (S34), the placement slot 541 photoelectric detection is used to prevent misoperation. If any link is abnormal (such as material not in place, abnormal pressure of the suction head 432), the control center will immediately suspend the process and trigger an alarm to avoid mold collision or workpiece damage. At the same time, the waiting position residence logic of the clamping mechanism 4 (such as continuous detection in S12 and S23) is linked to the status of the processing mechanism 5 to ensure accurate matching of the beats between processes. The comprehensive utilization rate of the equipment can reach more than 95%, greatly reducing the loss of unplanned downtime.

Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
