Description

Technical Field

[0001] This utility model relates to the field of metal material processing technology, specifically to a cooling mechanism and equipment for the production of aluminum alloy parts. Background Technology

[0002] In the production of aluminum alloy bolts, the cooling process is one of the key factors affecting product quality. Currently, the conventional cooling method mainly uses water cooling, which involves directly immersing the high-temperature aluminum alloy material in water or spraying it with cooling water for rapid cooling. However, this water cooling method, with its excessively rapid cooling rate, can cause significant thermal stress within the aluminum alloy material, leading to defects such as deformation and cracking, severely impacting the dimensional accuracy and mechanical properties of the bolts. Furthermore, rapid water cooling can also result in an uneven oxide layer on the material surface, increasing the difficulty and cost of subsequent processing. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cooling mechanism and equipment for the production of aluminum alloy parts, so as to solve the problem of aluminum alloy deformation caused by excessive cooling rate mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cooling mechanism for the production of aluminum alloy parts, comprising a carrier for supporting the parts to be cooled, the carrier including a receiving chamber for supporting the parts to be cooled and a conveyor belt connected to the receiving chamber, the bottom of the receiving chamber forming an angle with the conveyor belt, and the bottom of the receiving chamber being used to guide the parts to be cooled to move on the conveyor belt; the conveyor belt being used for upward transport and for turning the parts to be cooled for cooling; the conveyor belt also being used for downward transport to transport the parts to be cooled into the receiving chamber.

[0005] As a further improvement of this utility model, the cooling mechanism for the production of aluminum alloy parts described above is characterized in that an air-cooling mechanism is further provided above the receiving chamber and / or the conveyor belt, and the parts to be cooled are air-cooled by the air-cooling mechanism.

[0006] As a further improvement of this utility model, the cooling mechanism for the production of aluminum alloy parts described above is characterized in that the air-cooling mechanism has a ventilation pipe and a blower assembly, wherein the ventilation pipe is L-shaped and one end extends to the ground; the blower assembly is connected to one end of the ventilation pipe corresponding to the ground, and the other end extends to the position above the corresponding receiving chamber and / or conveyor belt.

[0007] As a further improvement of this utility model, the cooling mechanism for the production of aluminum alloy parts described above is characterized in that the bottom of the receiving chamber is a metal mesh structure.

[0008] As a further improvement of this utility model, according to the above-mentioned cooling mechanism for the production of aluminum alloy parts, the metal mesh structure is characterized in that a flipping drive assembly is connected to it, the flipping drive assembly including a hinge connection part and a linear drive device, for driving the metal mesh structure to flip downward around a horizontal axis to open the bottom of the receiving compartment.

[0009] As a further improvement of this utility model, according to the above-mentioned cooling mechanism for the production of aluminum alloy parts, the characteristic is that a transfer box is provided below the receiving chamber at the opening position of the metal mesh structure, and the opening size of the transfer box is larger than the projected area of ​​the metal mesh structure.

[0010] As a further improvement of this utility model, an equipment for the production of aluminum alloy parts is characterized by including a cooling mechanism for the production of aluminum alloy parts as described in any one of the above.

[0011] The beneficial effects of this invention are as follows: By cooperating with the conveyor belt and the receiving chamber of the carrier component, the angle between the bottom of the receiving chamber and the conveyor belt guides the parts to be cooled towards the conveyor belt. Simultaneously, the upward transport capability of the conveyor belt enables the parts to be cooled to be tumbled and cooled, avoiding the problem of excessively rapid cooling in traditional water cooling methods. This reduces the thermal stress generated inside the aluminum alloy material due to rapid cooling, effectively preventing material deformation and cracking, and ensuring the dimensional accuracy and mechanical properties of aluminum alloy products used for bolts. Furthermore, the conveyor belt can also be used to transport parts to be cooled by switching the transport direction; for example, parts from the previous process can be sent to the receiving chamber and then transported in the opposite direction, creating a tumbling effect on the conveyor belt.

Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0014] Reference Figure 1-2As shown in the figure, a cooling mechanism for aluminum alloy component production in this embodiment includes a carrier for carrying the component to be cooled. The carrier includes a receiving chamber 1 for carrying the component to be cooled and a conveyor belt 2 connected to the receiving chamber 1. The bottom of the receiving chamber 1 and the conveyor belt 2 form an angle, and the bottom of the receiving chamber 1 is used to guide the component to be cooled to move to the conveyor belt 2. The conveyor belt 2 is used for upward transport and for turning the component to be cooled for cooling. The conveyor belt 2 is also used for downward transport to transport the component to be cooled into the receiving chamber 1.

[0015] The side wall of the receiving bin 1 is fixedly connected to the frame of the conveyor belt 2 by bolts to ensure the relative position stability between the receiving bin 1 and the conveyor belt 2; the included angle between the bottom of the receiving bin 1 and the conveyor belt 2 can be set to 30°-60° (preferably 45°), and this included angle is fixed by the welded limiting block between the bottom of the receiving bin 1 and the frame of the conveyor belt 2 to prevent the included angle from changing due to the weight of the components; the conveyor belt 2 adopts a chain conveyor belt 2 or a mesh belt conveyor belt 2, and its two ends are respectively provided with a drive roller and a driven roller. The drive roller is connected to the servo motor through a coupling. The servo motor can be reversed by the controller, thereby controlling the conveyor belt 2 to transmit upward or downward.

[0016] In use, the high-temperature bolts, made of aluminum alloy or aluminum alloy bolts to be cooled, are conveyed downwards to the receiving chamber 1 via conveyor belt 2. Due to the preset angle between the bottom of the receiving chamber 1 and the conveyor belt 2, the parts to be cooled slide along the inclined surface of the bottom of the receiving chamber 1 under their own gravity and come into contact with the conveyor belt 2. At this time, the controller starts the servo motor to drive the conveyor belt 2 upwards. During the upward movement of the conveyor belt 2, the parts to be cooled move upwards synchronously. During this process, the parts will be slightly flipped due to the movement of the conveyor belt 2 and their own gravity, so that all surfaces of the parts can fully contact the surrounding air to achieve natural air cooling. The parts to be cooled do not need to contact cooling water. They rely on natural air cooling and the flipping of the conveyor belt 2 to achieve uniform cooling. The cooling rate is more gradual than that of traditional water cooling, effectively reducing the generation of thermal stress inside the aluminum alloy material. This fundamentally avoids material deformation and cracking caused by excessive thermal stress, ensuring the dimensional accuracy and mechanical properties of the bolt products.

[0017] In an optional configuration, an air-cooling mechanism 3 is also provided above the corresponding receiving chamber 1 and / or conveyor belt 2, through which the components to be cooled are air-cooled.

[0018] When the parts to be cooled are tumbled and cooled on the conveyor belt 2, the air cooling mechanism 3 is activated, and the air cooling mechanism 3 delivers airflow at room temperature or slightly below room temperature to the surface of the parts; when the parts are in the receiving chamber 1, the cold air blows directly onto the parts in the receiving chamber 1, accelerating the airflow on the surface of the parts and carrying away the heat from the surface of the parts; when the parts are transported upward and tumbled with the conveyor belt 2, the cold air can act on each tumbling surface of the parts, further improving the heat exchange efficiency.

[0019] Preferably, the air-cooling mechanism 3 has a ventilation pipe 31 and a blower assembly 32. The ventilation pipe 31 is L-shaped and one end extends to the ground. The blower assembly 32 is connected to the end of the ventilation pipe 31 corresponding to the ground and the other end extends to the position above the corresponding receiving chamber 1 and / or conveyor belt 2.

[0020] The blower assembly 32 itself has a certain weight. Placing it on the ground can reduce the connection strength requirements of the ventilation duct 31 and reduce safety hazards.

[0021] As a solution to increase air convection and improve cooling stability, the bottom of the receiving chamber 1 is a metal mesh structure. The metal mesh structure at the bottom of the receiving chamber 1 replaces the traditional solid bottom; when the part to be cooled is placed in the receiving chamber 1, the mesh of the metal mesh allows air to form vertical convection inside the receiving chamber 1, and external air can enter the bottom of the receiving chamber 1 through the mesh, carrying away the heat from the bottom of the part; cold air can penetrate through the mesh of the metal mesh to the bottom of the part, achieving simultaneous cooling of the upper and lower surfaces of the part.

[0022] In addition, as a convenient way to store materials, the metal mesh structure is connected to a flip drive assembly 4, which includes a hinge connection part 41 and a linear drive device 42, for driving the metal mesh structure to flip downward around the horizontal axis to open the bottom of the storage compartment 1.

[0023] The hinge connection 41 adopts a hinge structure. One side of it is fixed to the bottom of the side wall of the receiving chamber 1 by bolts, and the other side is connected to the edge of the metal mesh structure by bolts. The axis of the hinge connection 41 is set horizontally to ensure that the metal mesh structure can be flipped downward around this axis. The linear drive device 42 adopts a cylinder (or electric push rod). The cylinder body end is connected to the outer side wall of the receiving chamber 1 through a hinge seat, and the piston rod end of the cylinder is connected to the lower surface of the metal mesh structure through a hinge joint. When the part to be cooled is cooled in the receiving chamber 1 (or needs to be unloaded urgently), the linear drive device 42 drives the metal mesh structure to flip downward around the horizontal axis of the hinge connection 41. As the mesh structure flips, the bottom of the receiving chamber 1 gradually opens, and the cooled parts in the chamber slide down from the open bottom to the collection device below under their own gravity. After unloading is completed, the linear drive device 42 drives the metal mesh structure to flip upward and reset, and closes the bottom of the receiving chamber 1 again to allow for the cooling operation of the next batch of parts.

[0024] As a preferred solution for facilitating material transfer, a transfer box 5 is preferably provided below the storage bin 1 at the opening position corresponding to the metal mesh structure. The opening size of the transfer box 5 is larger than the projected area of ​​the metal mesh structure.

[0025] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
