Description

Technical Field

[0001] This utility model belongs to the field of die casting processing technology, specifically a hook guide device for heat treatment of die castings. Background Technology

[0002] Aluminum alloy die castings are widely used in many fields such as automotive, aerospace, and electronics due to their advantages of light weight, high strength, and good casting performance. However, the internal microstructure of die-cast aluminum alloy parts is often inhomogeneous, and their mechanical properties, corrosion resistance, and dimensional stability often fail to meet the requirements of high-end applications. Therefore, heat treatment, such as solution treatment and aging treatment, is usually required to improve their overall performance by altering the internal microstructure of the alloy.

[0003] Meanwhile, the patent specification with application number CN222165670U discloses an automatic material-changing heat treatment device for die casting parts, "including a baffle plate, a melting furnace fixedly installed at the bottom of the protective cover, several storage tanks arranged above the baffle plate, a discharge component arranged at the bottom of the several storage tanks, and a sealing component installed inside the protective cover. In this utility model, the several storage tanks can be used to change and convey die casting raw materials of different materials. When one die casting raw material needs to be conveyed, the solenoid valve at the bottom of one of the storage tanks is activated, and the die casting raw material particles in the storage tank fall onto the conveyor belt 2 by gravity. Then, the weight of the die casting raw material particles is sensed by a weight sensor. When the weight reaches a preset value, the solenoid valve is closed by the controller, and then the drive motor 2 is started to drive the die casting raw material particles to be conveyed and fall onto the conveyor belt 1, thereby quantitatively controlling the amount of die casting raw material particles added."

[0004] In most cases, existing hook guiding devices for heat treatment of die-cast parts require manual connection between the hook and the hanging ring. This manual connection not only increases the difficulty of operation but may also affect the production efficiency and safety of heat treatment. Furthermore, existing hook guiding devices for heat treatment of die-cast parts are difficult to adapt to the placement of workpieces of different heights, resulting in low work efficiency and limited practicality.

[0005] Therefore, a hook guide device for heat treatment of die-cast parts is proposed to address the above problems. Utility Model Content

[0010] Preferably, one end of each of the four reset springs is fixedly connected to one end of each of the four movable plates, and the other end of each of the four reset springs is fixedly connected to one side of the inner wall of the receiving groove.

[0011] Preferably, dovetail blocks are fixedly connected to both ends of the four movable plates, and dovetail grooves are provided on both sides of the inner walls of the four receiving slots to cooperate with the dovetail blocks.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 5As shown, this utility model provides a hook guiding device for heat treatment of die-cast parts, including a heating furnace body 1. Four vertical rods 7 are installed at the bottom of the heating furnace body 1, arranged in a rectangular array. One end of each of the four vertical rods 7 is provided with a support platform 3. Four cylinders 2 are fixedly connected to the top of the support platform 3. The output ends of the four cylinders 2 all penetrate the top of the heating furnace body 1 and are fixedly connected to connecting rods 21. The bottom ends of the four connecting rods 21 are all fixedly connected to hook bodies 29. A workpiece rack 4 is slidably provided at the top of the support platform 3, and four receiving slots 27 are opened at the top of the workpiece rack 4. Each of the four receiving slots 27 has a crossbar 26 fixedly connected to its inner surface. Each of the four crossbars 26 has a return spring 25 wrapped around its outer surface. Each of the four crossbars 26 has a movable plate 23 slidably sleeved on its outer surface. Each of the four movable plates 23 has a lifting ring 24 fixedly connected to its top end to cooperate with the hook body 29. When the cylinder 2 pushes the hook body 29 down, the hook body 29 squeezes the lifting ring 24. Under the action of the return spring 25, the movable plate 23 drives the lifting ring 24 to flexibly adjust its position and accurately engage with the hook body 29. This eliminates the need for manual fine alignment and reduces operation time and labor costs.

[0029] Specifically, a ramp 6 is fixedly connected to one end of the support platform 3. The ramp 6 facilitates the entry and exit of the workpiece rack 4. Operators can easily push the workpiece rack 4 containing the die-cast parts onto the support platform 3 via the ramp 6.

[0030] like Figures 1 to 5 As shown, both the top of the support platform 3 and the ramp 6 have two tracks 31, and the bottom of the workpiece rack 4 is equipped with four rollers 22. The lower inner wall of the two tracks 31 at the top of the support platform 3 is provided with two positioning grooves 32 for use with the rollers 22. The cooperation between the tracks 31 and the rollers 22 makes the movement of the workpiece rack 4 more stable and smooth. The positioning grooves 32 ensure that the workpiece rack 4 can be accurately positioned on the support platform 3, avoiding displacement of the workpiece rack 4 during the lifting process of the hook body 29, ensuring the stability of the docking between the hook body 29 and the lifting ring 24, and thus improving the reliability of the entire heat treatment process.

[0031] Furthermore, one end of each of the four return springs 25 is fixedly connected to one end of each of the four movable plates 23, and the other end of each of the four return springs 25 is fixedly connected to one side of the inner wall of the receiving groove 27. The connection method of the return springs 25 can provide elastic buffering and automatic reset function when the hook body 29 is docked with the lifting ring 24.

[0032] like Figures 1 to 5As shown, dovetail blocks 281 are fixedly connected to both ends of the four movable plates 23. Dovetail grooves 28 are provided on the inner walls of both sides of the four receiving slots 27 to cooperate with the dovetail blocks 281. The cooperation between the dovetail blocks 281 and the dovetail grooves 28 restricts the movement direction of the movable plates 23, so that they can only slide along the direction of the crossbar 26. This prevents the movable plates 23 from shaking or deviating during movement, ensuring the accuracy and stability of the docking between the lifting ring 24 and the hook body 29, and improving the precision of the entire lifting system.

[0033] It is worth noting that one end of each of the four vertical rods 7 is equipped with an electric slide rail 5. The four electric slide rails 5 are slidably connected to the support platform 3, which enables the device to adapt to workpiece racks 4 of different heights, thus expanding the applicability of the device. Whether the workpiece rack 4 is high or low, the height of the support platform 3 can be adjusted by the electric slide rails 5 to achieve precise docking between the hook body 29 and the lifting ring 24, thereby improving the versatility of the device in different working scenarios.

[0034] like Figures 1 to 5 As shown, the upper and lower ends of the four electric slide rails 5 are fixedly connected to limit plates 51. The two limit plates 51 on the same vertical side are fixedly connected to the corresponding vertical rods 7. The limit plates 51 can prevent the support platform 3 from sliding beyond the safe range on the electric slide rails 5, avoid accidents, ensure the safety and stability of the device during operation, and ensure that the entire heat treatment operation is carried out in a safe and controllable environment.

[0035] Working principle and process: First, the workpiece rack 4 containing the die-cast part is pushed onto the support platform 3 via the guide ramp 6 using rollers 22 along the track 31. The rollers 22 fall into the positioning groove 32 for precise positioning. Next, the cylinder 2 is activated, and the output end of the cylinder 2 pushes the connecting rod 21, causing the hook body 29 to descend. During the descent of the hook body 29, the lifting ring 24 is squeezed, which drives the moving plate 23 to compress the return spring 25. Under the elastic action of the return spring 25, the moving plate 23 drives the lifting ring 24 to move flexibly, and finally the lifting ring 24 is precisely engaged with the hook body 29. At this time, the cylinder 2 retracts, causing the workpiece rack 4 connected to the hook body 29 and the lifting ring 24 to rise, and the workpiece is sent into the heating furnace body 1 for heat treatment. If the workpiece rack 4 is too low, the electric slide rail 5 can be activated to adjust the height of the support platform 3 to a suitable position. After the heat treatment is completed, the cylinder 2 is activated again to lower the hook body 29, and the lifting ring 24 disengages from the hook body 29. Under the action of the return spring 25, the moving plate 23 returns to its original position. Finally, the workpiece holder 4 can be pushed out of the support platform 3 via the ramp 6.
