During the manufacturing process of the mobile phone middle frame, it is necessary to perform multiple processes such as heating, forging, bending, and trimming on it to form the final product. Before the material is forged, it needs to be heated first to make the material reach the predetermined forging temperature. Therefore, it is necessary to design a pre-forging heating device to heat the material before hot forging.

[0003] After the middle frame plate is hot forged, after the required external shape is formed by physical forging, in order to restore the material crystal image (internal microstructure), it is necessary to perform a solution heat treatment process on the hot-forged middle frame plate. After the temperature of the middle frame plate is raised above 460°C, it is maintained for a certain period of time and then quickly cooled, with rapid temperature drop; therefore, based on the solution heat treatment process requirements for the hot-forged aluminum alloy middle frame plate, designing a solution heat treatment production line for the hot-forged aluminum alloy middle frame plate helps to improve the solution heat treatment production efficiency and ensure the consistency of the solution heat treatment quality.

[0015] The beneficial effects of the present utility model are as follows:

[0016] In view of the defects and deficiencies existing in the prior art, the present utility model independently researches, designs and develops a solution line for solution treatment after hot forging of an aluminum alloy middle frame plate, which realizes automatic pushing and feeding, multi-layer and multi-channel contact heating, automatic material receiving, material blocking and material guiding, and synchronous transmission and cooling. While the middle frame plate is linearly pushed, its rapid heating is completed, and the contact heating effectively ensures the uniformity of surface heating. The multi-layer and multi-channel heating effectively increases the number of middle frame plates heated in a single transmission, improves the heating production capacity, and realizes the synchronization of the transmission and cooling of the middle frame plate, achieving rapid and efficient cooling and temperature reduction.

[0017] The utility model is applied to the field of automatic solution heat treatment after hot forging of aluminum alloy middle frame plates, aiming to provide a device that can automatically and rapidly heat up and cool the materials after hot forging to restore the crystal image of the internal materials of the middle frame plates after hot forging. Specifically, the utility model integrally includes a feeding part, a heating part, and a cooling part arranged successively along the X direction under pressure. At the feeding part, the middle frame plates after hot forging are fed, and an automatic pushing action is completed to make the middle frame plates enter the heating part. While the middle frame plates are advancing forward in the heating part, the heating part rapidly heats and raises their temperature. After reaching the preset temperature and heating time, the middle frame plates are led out from the heating part to the cooling part through a blanking mechanism, and rapid cooling is completed by the cooling part during the process of continuing to move along the X direction in the cooling part. Through the above structure, the automatic forward transmission of the middle frame plates is realized, and at the same time, the solution heat treatment process of heating first and then cooling is completed. Specifically, the heating part of the utility model uses a heating box with a rectangular box structure as the heating main body. Feed inlets and discharge outlets are respectively arranged at both ends of the heating box. A heating component is arranged inside the heating box. For aluminum alloy parts with a plate-like structure, the utility model uses a plate-like heating plate as the heating carrier. Multiple heating tubes are inserted inside the heating plate. After the heating tubes are energized to generate heat, the heat is conducted to the heating plate. The heating plate includes multiple pieces arranged at intervals up and down. A heating layer is formed between adjacent two heating plates. Partition bars are arranged in the heating layer, and the heating layer is divided into multiple heating channels by the partition bars. This multi-layer and multi-channel direct contact heating method can multiply the heating efficiency. When the middle frame plates are linearly moving in the heating channels, their upper and lower surfaces are respectively attached to the upper and lower heating plates to achieve contact heating, effectively increasing the heating area and heating uniformity. The heating temperature is RT - 1000°C, and it can simultaneously heat materials such as aluminum alloy and titanium alloy.Based on the curing design of the structural position of the multi-layer heating layer in the heating box, the feeding mechanism set in the feeding part of the present utility model simultaneously has a linear drive along the X direction and a drive along the vertical direction. The power output by the drive motor drives the screw rod to rotate, and the threaded connection (helical tooth connection) between the screw rod and the drive shaft drives the drive shaft to move up and down along the vertical direction to adjust the height, so as to facilitate aligning the heating layers at different heights during the feeding process, so that the push rod can push the middle frame plate on the material seat into the heating channels of the heating layers at different heights. At the same time, the number of material grooves opened on the material seat is the same as the number of heating channels in the heating layer; in addition, to facilitate connecting and exporting the heated middle frame plate, the present utility model is provided with a blanking mechanism outside the discharge port of the heating mechanism. The blanking mechanism uses an inclined support with a rectangular frame structure arranged obliquely downward as the conduction structure. One end of the inclined support extends into the discharge port of the heating mechanism, and the other end extends obliquely downward outward. A plurality of support rods are arranged in parallel and spaced inside it. The support rods are sleeved with freely rotatable rollers. The middle frame plates in the heating channels are arranged one by one along the X direction and are gradually linearly moved under the action of the push rod of the feeding mechanism to complete heating, and then are discharged through the discharge port. After being picked up by the inclined support, they are led downward along the inclined support to the conveying mechanism in the subsequent cooling part. Based on the heating mechanism including multiple heating layers at different height positions, in order to accurately pick up the middle frame plate, the whole inclined support is driven by the lifting cylinder below to adjust the height position in the vertical direction. At the same time, a feeding cylinder and a material blocking plate are also arranged below the inclined support. The feeding cylinder drives the material blocking plate to move up and down, so as to pass through the gap space between two adjacent support rods on the inclined support and block or open the discharge port, so as to automatically control the blanking time of the middle frame plate; the middle frame plate imported onto the conveying mechanism continues to be transported backward along the X direction by the material belt of the conveying mechanism and passes successively through the air knife air cooling assembly, the eddy current cooling assembly and the axial flow fan assembly erected on the conveying mechanism, and is rapidly cooled during the automatic transportation process. On the premise of ensuring rapid cooling and temperature reduction, the cooling efficiency is effectively improved. Description of the Drawings

[0066] Furthermore, the utility model designs a solid solution production line for aluminum alloy middle frame plates after hot forging, which realizes automatic feeding and material conveying, multi-layer and multi-channel contact heating, automatic material receiving, material blocking and guiding, and synchronous transmission and cooling. While the middle frame plate is linearly pushed, its rapid heating is completed, and the contact heating effectively ensures the uniformity of surface heating. The multi-layer and multi-channel heating effectively increases the number of middle frame plates heated in a single transmission, provides heating productivity, and realizes the synchronization of the transmission and cooling of the middle frame plate, achieving rapid and efficient cooling. The utility model is applied to the automatic solid solution field of aluminum alloy middle frame plates after hot forging, aiming to provide a device for realizing the automatic and rapid heating and cooling of materials after hot forging to restore the crystal image of the internal material of the middle frame plate after hot forging. Specifically, the utility model integrally has a feeding part, a heating part, and a cooling part sequentially arranged along the X direction under pressure. At the feeding part, the middle frame plate after hot forging is fed, and the automatic feeding action is completed, enabling the middle frame plate to enter the heating part. While the middle frame plate is moving forward by pushing in the heating part, the heating part realizes rapid heating and temperature rise for it. After reaching the preset temperature and heating time, the middle frame plate is led out from the heating part to the cooling part through the blanking mechanism, and during the process of continuing to move along the X direction in the cooling part, rapid cooling is completed through the cooling part. Through the above structure, the solid solution process of first heating and then cooling is completed while the middle frame plate is automatically transmitted forward. Specifically, the heating part of the utility model uses a heating box with a rectangular box structure as the heating main body. Feed inlets and discharge outlets are respectively arranged at both ends of the heating box. A heating component is arranged inside the heating box. For aluminum alloy parts with a plate structure, the utility model uses a heating plate with a plate structure as the heating carrier. Multiple heating tubes are inserted inside the heating plate. After the heating tubes are energized to generate heat, the heat is conducted to the heating plate. The heating plate includes multiple pieces arranged at intervals up and down. A heating layer is formed between adjacent two heating plates. Partition bars are arranged in the heating layer, and the heating layer is divided into multiple heating channels by the partition bars. This multi-layer and multi-channel direct contact heating method can multiply the heating efficiency. When the middle frame plate moves linearly in the heating channel, its upper and lower surfaces are respectively attached to the upper and lower heating plates to realize contact heating, effectively increasing the heating area and heating uniformity. The heating temperature is RT - 1000 °C, and it can simultaneously realize the heating of materials such as aluminum alloy and titanium alloy.Based on the curing design of the structural positions of multiple heating layers in the heating box, the feeding mechanism provided in the feeding part of the present utility model simultaneously has a linear drive along the X direction and a drive in the vertical direction. The power output by the drive motor drives the screw rod to rotate, and the screw rod is threadedly connected (helical gear connection) to the drive shaft to drive the drive shaft to move up and down in the vertical direction, so as to adjust the height and facilitate aligning the heating layers at different heights during the feeding process, so that the push rod can push the middle frame plate on the material seat into the heating channels of the heating layers at different heights. At the same time, the number of material grooves opened on the material seat is the same as the number of heating channels in the heating layer; in addition, to facilitate connecting and exporting the heated middle frame plate, the present utility model is provided with a blanking mechanism outside the discharge port of the heating mechanism. The blanking mechanism uses an inclined support with a rectangular frame structure arranged obliquely downward as the conduction structure. One end of the inclined support extends into the discharge port of the heating mechanism, and the other end extends obliquely downward outward. A plurality of support rods are arranged in parallel and spaced inside it. Rotatable rollers are sleeved on the support rods. The middle frame plates in the heating channels are arranged one by one along the X direction and are gradually linearly moved under the action of the push rod of the feeding mechanism to complete heating, and then are discharged through the discharge port. After being picked up by the inclined support, they are led downward along the inclined support to the conveying mechanism in the subsequent cooling part. Based on the fact that the heating mechanism includes multiple heating layers at different height positions, in order to accurately pick up the middle frame plate, the whole inclined support is driven by the lifting cylinder below to adjust the height position in the vertical direction. At the same time, a discharging cylinder and a material blocking plate are also provided below the inclined support. The discharging cylinder drives the material blocking plate to move up and down, so as to pass through the gap space between two adjacent support rods on the inclined support and block or open the discharge port, so as to automatically control the blanking time of the middle frame plate; the middle frame plate imported onto the conveying mechanism continues to be transmitted backward along the X direction by the material belt of the conveying mechanism and successively passes through the air knife air cooling assembly, the eddy current cooling assembly and the axial flow fan assembly erected on the conveying mechanism, and is rapidly cooled during the automatic transmission process. On the premise of ensuring rapid cooling, the cooling efficiency is effectively improved.

Those skilled in the art can make certain modifications under the inspiration of this embodiment. Therefore, all equivalent changes or modifications made in accordance with the scope of the present utility model patent are within the scope of the claims of the present utility model patent.
