Description

Technical Field

[0001] This utility model relates to the field of forging production, and in particular to a forging copper valve loading and unloading device. Background Technology

[0002] In the copper valve forging production process, the traditional manual loading and unloading method has many drawbacks: operators need to frequently come into contact with high-temperature copper bars and forging dies, posing serious safety hazards; manual operation is inefficient and labor-intensive, making it difficult to meet the high-efficiency requirements of modern production. Existing automated loading and unloading equipment generally suffers from complex structures and insufficient positioning accuracy, especially lacking effective integration in the gripping, precise placement, and receiving of forged products after high-temperature copper bars. Most equipment can only achieve simple material transfer functions and cannot simultaneously complete the combined operations of loading and unloading. In addition, the motion mechanisms of existing equipment mostly use a single drive method, which makes it difficult to meet the dual requirements of high-speed motion and precise positioning, and the reliability of long-term operation in high-temperature environments needs to be improved. These problems seriously restrict the automation level of copper valve forging production and the improvement of product quality. Utility Model Content

[0011] According to some embodiments of the present invention, the receiving unit further includes a weighing force sensor, which is connected to the control system and is used to detect the weight of the receiving tray, thereby determining whether the forged copper valve product has fallen into the receiving tray.

[0012] The benefits are that the addition of the weighing force sensor can monitor in real time whether the product falls accurately into the receiving tray, effectively avoiding missed or incorrect connections and improving the reliability of product quality control.

[0013] According to some embodiments of the present invention, the X-axis drive unit includes a first fixed plate, a first slide rail disposed on the first fixed plate, a first slide plate mounted on the first slide rail, and a first servo motor mounted on the first slide plate.

[0038] The following is for reference. Figures 1-4 A forged copper valve loading and unloading device is described in detail with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0039] like Figure 1As shown, this forging copper valve loading and unloading device mainly consists of two parts: a loading and unloading mechanism and a motion mechanism. Through modular design, it achieves a complete process flow of automatic material handling, precise positioning, and unloading during copper valve forging. The loading and unloading mechanism includes two functional modules: a clamping unit and a receiving unit. The clamping unit adopts a structure design where a propulsion cylinder 110 drives the workpiece gripper 100. The surface of the workpiece gripper 100 is coated with a high-temperature resistant ceramic coating, ensuring sufficient gripping force and effectively resisting high-temperature oxidation, thus improving the durability and reliability of the clamping unit. This clamping unit can stably and reliably grip high-temperature copper bars and accurately place them into the lower die of the forging mold, completely avoiding the safety hazards of manual operation. Figure 4 As shown, the receiving unit uses a rotary cylinder 130 to rotate a rectangular stainless steel receiving tray 120. The receiving tray 120 has a retaining edge 260 on its outer periphery and a discharge notch 270 in the rotating direction. This special design ensures sufficient receiving area while effectively preventing product slippage and ensuring smooth sliding into the discharge chute, achieving automatic receiving and efficient unloading of forged products. The receiving unit also integrates a weighing force sensor 140, which monitors in real time whether the product accurately falls into the receiving tray 120, effectively avoiding missed or incorrect reception and greatly improving the reliability of product quality control.

[0040] It should be noted that, as Figure 1 and Figure 2 As shown, the motion mechanism employs a combination of X-axis and Y-axis dual drive units. By leveraging the complementary advantages of two different transmission methods, it perfectly balances the dual requirements of high-speed motion and precise positioning. The X-axis drive unit includes components such as a first fixed plate 150, a first slide rail 160, a first sliding plate 170, and a first servo motor 180. It utilizes a gear 200 and rack 190 transmission structure, featuring high transmission efficiency, good positioning accuracy, and strong load-bearing capacity, meeting the needs of long-term continuous operation. Position detection sensors 210 are installed at both ends of the first fixed plate 150, ensuring the motion mechanism accurately reaches the target position, greatly improving the device's positioning accuracy and repeatability. The Y-axis drive unit includes a second slide rail 220 and a second servo motor 230 mounted on the first sliding plate 170. It employs a lead screw 250 transmission method, offering advantages such as good self-locking, smooth transmission, and high precision, making it particularly suitable for precise vertical positioning. This dual-axis drive method achieves precise positioning of the loading and unloading mechanism in three-dimensional space, meeting the operational needs of different workstations.

[0041] Specifically, such as Figure 3As shown, the clamping unit includes a mounting bracket 280 for mounting the push cylinder 110. The front end of the mounting bracket 280 has a boss 290 for mounting the workpiece gripper 100. The boss 290 has a mounting opening 300. The workpiece gripper 100 is mounted on a rocker arm 310 above the mounting opening 300, a pull rod 320 passing through the mounting opening 300, a bracket 330 below the mounting opening 300, and swing arms 340 swinging on both sides of the bracket 330. The inner side of the swing arms 340 has a slot 350. The push cylinder 110 drives the pull rod 320 up and down via the rocker arm 310, thereby causing the swing arms 340 to open and close. This clamping unit uses a linkage mechanism of rocker arm 310-pull rod 320-swing arm 340, which is compact and has efficient transmission. The push cylinder 110 drives the pull rod 320 up and down via the rocker arm 310, enabling the swing arms 340 to open and close precisely, ensuring stable and reliable clamping of the copper rod. The slot 350 design enhances clamping friction, preventing the high-temperature copper rod from slipping out, and is suitable for high-intensity operations during forging. The bracket 330 has a fixing block 360 located between the two swing arms 340, each swing arm 340 capable of clamping a copper rod. The fixing block 360 allows the clamping unit to stably clamp two copper rods simultaneously, improving efficiency per operation. The symmetrical swing arm 340 structure, driven by a single cylinder, achieves coordinated operation of both swing arms 340, resulting in uniform clamping force distribution, preventing copper rod displacement, and is suitable for batch forging production, reducing the frequency of manual intervention and improving automation.

[0042] The working process of this forging copper valve loading and unloading device is as follows: First, the X-axis drive unit drives the clamping unit to move above the heating furnace (not shown in the figure), and the Y-axis drive unit drives the clamping unit to descend. The push cylinder 110 drives the workpiece clamping jaw 100 with a high-temperature ceramic coating to clamp the high-temperature copper rod. Then, the Y-axis drive clamping unit rises, and the X-axis drive unit accurately transports the copper rod between the upper and lower dies of the forging mold. The Y-axis drive unit drives the clamping unit to descend and put the high-temperature copper rod into the lower die. At the same time, the push rod of the upper die pushes the product out and falls into the receiving tray 120. The weighing force sensor 140 monitors the receiving status in real time. After confirming that the copper valve product has been received, the X-axis drive unit drives the clamping unit to move above the discharge chute (not shown in the figure). The rotary cylinder 130 drives the stainless steel receiving tray 120 to flip and unload the copper valve product into the discharge chute and then return to the center. The above cycle is repeated. Throughout the process, the control system precisely coordinates the timing of the actions of each mechanism, and the X-axis and Y-axis drive units work together to achieve rapid and accurate positioning in three-dimensional space, completing the fully automated operation from material picking, feeding, receiving to unloading, which significantly improves production efficiency and operational safety.

[0043] This device is equipped with an intelligent control system that precisely coordinates the timing of the loading / unloading mechanisms and motion mechanisms, making the entire device's operation more precise and orderly, and greatly improving the automation and stability of the production process. The control system forms a closed-loop control system with various sensors and actuators, ensuring that each action is completed accurately. The entire device adopts a modular design, with a compact and reasonable structure, stable and reliable operation, and is particularly suitable for high-temperature, high-strength forging production environments. All key components undergo special processing, such as the stainless steel receiving tray 120, which has excellent high-temperature resistance and mechanical strength, and the workpiece grippers 100 with a high-temperature ceramic coating, ensuring long-term reliable operation of the equipment under harsh conditions. The implementation of this device significantly improves the automation level of copper valve forging, significantly increases production efficiency, reliably guarantees product quality, and completely eliminates the safety hazards of manual operation.
