Description

Technical Field

[0001] This invention belongs to the field of edge trimming machine technology, and particularly relates to a floating slide edge trimming machine. Background Technology

[0002] The trimming process, a crucial step in the die-casting production chain of "die casting → trimming → shot blasting → machining," plays an indispensable role, especially in the manufacturing of automotive aluminum alloy parts. It is a vital post-processing step. Essentially, it involves precisely and controllably removing and cleaning excess material inevitably formed on the casting due to the forming process requirements. This includes runners left by the gating system, overflow channels generated by molten metal flow, and burrs and flash formed in the mold gaps. This effectively separates the finished product from the design specifications. The quality and precision of this process directly determine the final dimensional accuracy, surface finish, and subsequent assembly and matching performance of the automotive aluminum alloy parts within the vehicle system. If the edge trimming operation is not handled properly, such as by selecting the wrong tool, setting unreasonable process parameters, or having a deviation in the positioning reference, it is very likely to cause local deformation of the product, accidental damage to the internal matrix structure, and even have to increase the correction time and cost in subsequent processing stages, which will have a significant negative impact on the efficiency and economy of the entire production process.

[0003] Traditional burr removal processes have long relied on manual labor by operators using files and various power tools, relying on their individual skills and accumulated experience to manually grind and remove burrs. In this process, due to individual differences and instability in manual operation, product consistency and final quality are difficult to guarantee, while overall production efficiency remains low, and the difficulty and cost of manual management remain high. With the market's increasing demands for the precision and appearance of die-cast parts, coupled with the continuous rise in labor costs, this traditional and highly manual deburring method is facing inevitable elimination. In contrast, adopting a rationally designed and optimized edge-trimming die process can ensure a high degree of consistency in every product produced, thereby effectively improving production efficiency and significantly reducing reliance on on-site operators, achieving a key transformation towards cost reduction, efficiency improvement, and production automation.

[0004] Currently, the edge-cutting equipment used in the industry generally adopts a combination of upper and lower edge-cutting dies to process the edges of various structural components. However, this conventional approach often reveals a series of obvious defects and shortcomings in actual production applications, mainly including the following aspects: First, the common operating mode is to fix the upper and lower edge-cutting dies before starting the edge-cutting operation. However, under long-term, high-frequency use, the fixed lower edge-cutting die often exhibits the disadvantage of insufficient operational flexibility and convenience. For example, adjusting its position, changing the die, or performing routine maintenance are all cumbersome, which directly restricts and affects the efficiency of the overall processing flow to varying degrees. Second, in actual operation, the lower edge-cutting die usually lacks an effective buffer or shock absorption mechanism. This makes the die prone to accelerated wear, deformation, or other forms of mechanical fatigue under continuous impact and pressure. Over time, this will seriously damage the structural integrity and performance stability of the die, thereby significantly shortening its effective service life and potentially leading to additional maintenance costs and production interruption risks.

The upper buffer cover is fixedly connected to the lower buffer cover. The spring is located inside the lower buffer cover and connected to the buffer block located inside the upper buffer cover. The contact plane of the buffer block is higher than the contact plane of the upper buffer cover. The buffer block is connected to the transfer template to buffer the transfer template.

[0012] In a preferred embodiment of the present invention, a side positioning part is provided on the frame. The side positioning part includes a positioning cylinder and a positioning block.

[0013] In a preferred embodiment of the present invention, an L-shaped recessed space is formed on the support arm, a continuous guide rail is provided in the recessed space, the platform is connected to the guide rail by a slider, and a limit block is provided at the end of the guide rail.

[0019] The floating slide trimming machine of this invention employs a transfer unit in conjunction with a transfer template. A driver propels the platform precisely along the length of the support arm, enabling stable and efficient reciprocating movement of the trimming die. Compared to traditional fixed trimming dies, this dynamic adjustment mechanism allows for rapid adjustment of the working position during production based on the processing requirements of different workpiece specifications. Replacement of the trimming die eliminates the need for complex disassembly and recalibration. Routine maintenance can be performed solely through the translation of the platform, significantly reducing operational difficulty and time costs, and drastically decreasing the proportion of non-processing time. This effectively improves the continuity and production efficiency of the overall processing flow. Meanwhile, a flexible buffer connection between the transfer template and the platform is achieved through a buffer component. The synergistic effect of the internal springs and buffer blocks forms a multi-level shock absorption system. During the mold closing operation of the upper and lower cutting molds, it can effectively absorb the impact force and high-frequency vibration generated at the moment of mold closing. This buffer mechanism not only reduces the direct damage of the impact force to the cutting edge and cavity of the lower cutting mold, but also delays the wear, deformation and other fatigue phenomena caused by long-term stress on the mold, which greatly extends the average service life of the mold, significantly reduces the mold replacement frequency and maintenance cost, fundamentally reduces the risk of production interruption caused by mold failure, and ensures the stable operation of the production line.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0032] This embodiment provides a floating slide trimming machine. The floating slide trimming machine uses a transfer unit 10 in conjunction with a transfer template 20. A driver 12 drives a platform 13 to move precisely along the length of the support arm 11, stably and efficiently reciprocating the trimming die 2000. Compared to a traditional fixed trimming die 2000, this dynamic adjustment mechanism can quickly adjust the working position according to the processing requirements of different workpiece specifications. Replacing the trimming die 2000 does not require complex disassembly and recalibration. Routine maintenance involves inspecting key components by moving the platform 13 horizontally, reducing operational difficulty and time costs, minimizing non-processing time, and improving the continuity and efficiency of the overall processing flow. Simultaneously, a buffer component 30 provides a flexible buffer connection between the transfer template 20 and the platform 13. Internal springs 33 and buffer blocks 34 work together to form a multi-stage shock absorption system, absorbing impact and high-frequency vibrations during mold closing, reducing direct damage to the cutting edge and cavity of the trimming die 2000, delaying mold fatigue, extending the average mold lifespan, reducing mold replacement frequency and maintenance costs, minimizing production interruption risks, and ensuring stable production line operation.

[0033] Combination Figures 1 to 9As shown, the floating slide trimming machine of this embodiment includes an upper trimming die 1000, a lower trimming die 2000, a transfer unit 10, and a transfer platen 20. The upper trimming die 1000 and the lower trimming die 2000 cooperate with each other; when they complete the mold closing action, they can efficiently perform precision trimming operations on metal structural parts. The transfer unit 10 undertakes the movement and support functions of the entire device, and specifically consists of support arms 11, a driver 12, and a platform 13. Two support arms 11 are provided, arranged parallel to each other in a spatial layout, thus providing a stable and reliable track foundation for movement. The driver 12 is installed on the outer side of one of the support arms 11, and it can continuously output smooth and controllable power to drive the platform 13 to perform precise linear reciprocating motion strictly along the length direction of the support arm 11. The two platforms 13 are positioned one-to-one with the two support arms 11. This symmetrical design ensures that the force on each part of the device remains uniform and balanced throughout the entire transfer and positioning process, effectively avoiding problems such as uneven loading or vibration caused by uneven force. The transfer template 20 is flexibly connected to the two platforms 13 through a buffer 30 with buffering and adjustment functions, while the trimming die 2000 is directly and firmly fixed on the transfer template 20. Therefore, during operation, the trimming die 2000 can completely follow the transfer template 20 in a synchronous and stable translational movement, thereby ensuring the continuity and processing accuracy of the trimming process.

[0034] In this embodiment, the buffer 30 is specifically composed of four core components: a lower buffer cover 31, an upper buffer cover 32, a spring 33, and a buffer block 34. During actual installation, the lower buffer cover 31 is pre-fixed to the upper surface of the platform 13, serving as the basic support for the entire buffer structure. Subsequently, the upper buffer cover 32 is precisely aligned with the lower buffer cover 31 using several high-strength bolts and securely locked, forming a stable containment space for the spring 33. The spring 33 is placed in a specific cavity inside the lower buffer cover 31, with one end of the spring 33 stably abutting against the bottom wall of the inner cavity of the lower buffer cover 31, and the other end extending upwards to connect with the bottom end of the buffer block 34, which extends into the cavity of the upper buffer cover 32. After all assembly is complete, the top surface of the buffer block 34 must be higher than the contact surface of the top of the upper buffer cover 32, allowing the top of the buffer block 34 to directly and tightly fit against the bottom surface of the transfer template 20. During the mold closing process of mechanical operation, when an impact force is generated, the impact is transmitted to the buffer block 34, which compresses the spring 33. Through the controllable elastic deformation of the spring 33, the impact energy is effectively absorbed and dispersed, thereby achieving structural buffering and safety protection for the entire moving mold plate 20 and the cutting edge lower mold 2000.

[0035] In this embodiment, the bottom end of the buffer block 34 is always located inside the cavity of the lower buffer cover 31 under normal operating conditions, and a stroke gap is pre-set between its bottom end and the inner wall of the upper buffer cover 32. To precisely control and adjust the buffering performance, a replaceable shim 130 is specially fitted onto the outer circumference of the buffer block 34 at this stroke gap. This shim 130 adopts a modular design, allowing for flexible adjustment of the maximum buffering stroke distance that the buffer block 34 can achieve during movement by replacing shims 130 with different thicknesses. This adjustable design enables the entire buffer structure to effectively adapt to mold-closing impact forces of different sizes and intensities, significantly enhancing its application adaptability and working condition matching capability. Furthermore, a bushing 140 is tightly fitted between the outer surface of the buffer block 34 and the inner wall of the upper buffer cover 32. The main function of this bushing 140 is to act as a lubrication and isolation component between the moving parts, effectively reducing friction and wear between the buffer block 34 and the inner wall of the upper cover when the buffer block 34 reciprocates up and down. This not only ensures that the buffer block 34 moves more smoothly and steadily throughout the entire process, reducing the risk of jamming, but also significantly improves the long-term operational reliability and overall service life of the entire buffer structure by reducing the wear and tear on key moving parts.

[0036] The floating slide trimming machine of this embodiment also includes a frame 40. The trimming upper die 1000 is hoisted and installed above the frame 40 via a support structure 50. A hydraulic cylinder 41 is installed on the top of the frame 40. The extended end of the hydraulic cylinder 41 is fixedly connected to the trimming upper die 1000, which can smoothly and accurately drive the trimming upper die 1000 to move vertically, thereby efficiently completing a series of automated actions such as die closing and trimming, and die opening and unloading, greatly improving work efficiency and operational safety. In the middle platform area of ​​the frame 40, a receiving plate 42 is installed. The receiving plate 42 is designed to be located directly below the trimming upper die 1000 to receive the trimming lower die 2000. The trimming lower die 2000 is installed on a movable platform 13. Driven by the drive system, it can perform precise reciprocating linear motion along a preset path between the initial preparation position of the support arm 11 and the working position below the receiving plate 42. The specific workflow is as follows: During the loading stage, the lower cutting die 2000 moves horizontally to one side of the support arm 11. This provides a spacious position, facilitating safe and convenient material unloading for the operator. After the unloading process is completed, the lower cutting die 2000 automatically moves to the corresponding position below the receiving platform 42, precisely aligned with the upper cutting die 1000, preparing for subsequent cutting operations. After the cutting process is completed, the lower die moves back to the outer position, allowing operators to unload or inspect the material. This reciprocating motion design makes the entire operation process seamless, smoother, and more efficient, reducing manual intervention and material transfer time. The support arm 11, used to support moving parts, is securely mounted on the sturdy platform of the frame 40 via multiple vertically arranged and evenly distributed fixing brackets 60 at its bottom. This multi-point fixing method greatly ensures the overall rigidity and stability of the support arm 11, effectively preventing any shaking or positional shift during high-speed operation or load changes, thus guaranteeing processing accuracy.

[0037] In addition, the frame 40 is equipped with a side positioning part 70 for auxiliary positioning of the transfer template 20. The side positioning part 70 includes a positioning cylinder 71 and a positioning block 72 that cooperates with it. During actual operation, after receiving a signal, the positioning cylinder 71 pushes the positioning block 72 outward according to a predetermined stroke, so that it accurately and reliably enters the preset slot 202 on the side of the transfer template 20, thereby achieving clamping and fixing of the transfer template 20 and ensuring that it remains stable and does not deviate in subsequent operations.

[0038] In this embodiment, the support arm 11 is machined to form a recessed space 111 with an L-shaped cross-section. The recessed space 111 is designed with an internal guide rail 80. The lower surface of the platform 13 is securely fixed to a matching slider 90 via pre-positioned mounting holes and high-strength bolts. The slider 90 and the guide rail 80 form a high-precision sliding pair, enabling smooth linear movement of the platform 13 along the guide rail 80. Furthermore, a limiting block is installed at the extended end of the guide rail 80. This design effectively limits the maximum sliding stroke of the slider 90, preventing it from accidentally detaching from the guide rail 80 during movement and ensuring the safety of the mechanism's operation.

[0039] Furthermore, a side guide block 100 is fixedly installed on the inner wall of the sunken space 111. The lateral surface of the side guide block 100 is integrally molded to form a strip-shaped protrusion 101 extending longitudinally along the sliding direction. On the corresponding side surface of the transfer template 20, a precisely shaped guide groove 201 is precisely formed. A linear sliding plate 110 is embedded and fixed inside the guide groove 201. When the transfer template 20 is assembled in place, the protrusion 101 on the side guide block 100 will precisely engage with the guide groove 201 of the transfer template 20 and form a sliding engagement with the linear sliding plate 110 embedded therein. This guiding mechanism can precisely guide and constrain the movement trajectory of the transfer template 20 from the side throughout the entire process of the transfer template 20 moving synchronously with the platform 13. It not only ensures the directional accuracy and stability of the transfer template 20 during the movement process, but also significantly enhances its ability to resist lateral loads or disturbances, thereby comprehensively improving the lateral structural stability and overall operational reliability of the transfer template 20 in the working state.

[0040] Specifically, in this embodiment, the output end of the driver 12 is provided with a transmission structure 120. The transmission structure 120 specifically adopts a gear and rack transmission pair design, wherein the transmission gear 121 is coaxially fixed on the output shaft of the driver 12, and the corresponding transmission rack 122 is firmly installed on the bottom of the platform 13 along the length direction of the support arm 11. Through this arrangement, a stable and continuous meshing relationship is formed between the transmission gear 121 and the transmission rack 122. When the driver 12 starts to rotate and output torque, the meshing transmission is activated, thereby accurately converting the rotational motion of the driver 12 into the linear displacement of the platform 13 along the length direction of the support arm 11. This transmission method ensures that the platform 13 runs smoothly and accurately throughout the entire movement process, with almost no shaking or deviation, thus achieving excellent transmission accuracy and positioning accuracy. Therefore, this design can continuously and stably meet the high-precision requirements for position control during workstation switching, improving the reliability and repeatability of the entire system.

[0041] In actual production, the operator of the floating slide trimming machine of this embodiment first needs to fix the structural component to be processed onto the lower trimming die 2000. After confirming that the structural component is installed correctly, the operator starts the equipment operation command. At this time, the driver 12 starts working, driving the platform 13, which carries the moving template 20 and the lower trimming die 2000, to move smoothly and at a constant speed along the high-precision linear guide rail 80 through the transmission mechanism. The platform 13 continues to move inward until the lower trimming die 2000 accurately reaches the preset working position directly below the upper trimming die 1000. The positioning pin configured on the side of the equipment will extend to accurately lock and position the moving template 20. This mechanism ensures that the lower trimming die 2000 and the upper trimming die 1000 are highly aligned in three-dimensional space, laying a solid foundation for subsequent high-quality trimming operations.

[0042] Subsequently, the system controls the hydraulic cylinder 41 to begin operation, driving the upper cutting die 1000 to descend smoothly in the vertical direction, achieving closure with the lower cutting die 2000, thereby performing the die-cutting operation. At the moment of contact and pressure application during die closing, a certain amount of mechanical impact force is inevitably generated. This impact force is mainly transmitted and channeled through the moving platen 20. The moving platen 20 is connected to the platform 13 via the buffer 30. The buffer block 34 of the buffer 30, as the first-level force-bearing component, first receives the impact and presses downward, thereby compressing the spring 33 mounted below or inside it. The spring 33, through its own elastic deformation, efficiently absorbs and stores most of the impact energy. Simultaneously, the buffer block 34 itself is made of a special composite material with high damping characteristics, which can further consume and attenuate the remaining vibration and fluctuations through molecular friction and viscoelastic deformation within the material, thus achieving multi-level composite buffering and shock absorption from mechanical to material perspectives. This system significantly reduces the peak stress and vibration transmitted to the lower die 2000, effectively protecting the precision cutting edges and the structural integrity of the forming cavity on the lower die 2000, and greatly extending the service life of the die.

[0043] After the trimming process is completed, the hydraulic cylinder 41 moves in the reverse direction as instructed, driving the upper trimming die 1000 to move smoothly upwards and complete the die opening. Immediately afterwards, the driver 12 starts again, driving the platform 13, carrying the trimmed workpiece, to move in the reverse direction along the guide rail 80, returning to the ready position outside the equipment. At this point, the operator can easily and quickly remove the finished workpiece from the lower die and prepare for the clamping of the next batch of workpieces. Thus, a complete, efficient, and well-protected automated trimming process is successfully completed.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
