[0003] The turbine housing is part of the turbocharger, typically located on the exhaust side, and functions similarly to a snail-shaped heat shield. It needs to operate continuously under high temperature and pressure conditions; therefore, the manufacturing precision of the turbine housing is relatively important, especially the surface material, where the processing details significantly impact its lifespan.
[0004] In existing automotive turbine housing production lines, billets typically undergo multiple processing steps, such as slurry application, spraying, and sanding, before being rapidly transferred to the drying area. Especially during the concentrated drying of large quantities of billets, production line layout issues can negatively impact drying efficiency or result in excessively large drying areas.

[0039] Please see Figure 1-4 This embodiment describes a shell-making and drying line, which includes:
[0040] Material feeding area 1;
[0041] Top drying line 2, the starting end of which is connected to the discharge area via a lifting ramp 21;
[0042] The intermediate drying line 3 is located below the top drying line 2, and the starting end of the intermediate drying line 3 is connected to the ending end of the top drying line 2 through the first transfer ramp 31.
[0043] Bottom drying line 4 is located below the middle drying line 3, and the starting end of the bottom drying line 4 is connected to the ending end of the middle drying line 3 through the second transfer ramp 41.
[0044] The unloading area 5 is connected to the end of the bottom drying line 4 via the third transfer ramp 51.
[0045] Dryer 6 is located on one side of the top drying line 2, the middle drying line 3, and the bottom drying line 4.
[0046] With the help of the above-mentioned device, in actual use, the operator first places the preset number of blanks one by one in the feeding area 1. With the help of the corresponding robotic arm and other mechanisms, the blanks are suspended from the feeding area 1 on the lifting ramp 21 and the shell drying line is started.
[0047] Then, the lifting ramp 21 lifts the billet and transports it to the beginning of the top drying line 2. The top drying line 2 drives the billet forward, so that the position of the top drying line 2 is filled with billet one by one. During the filling process, the billet on the top drying line 2 is heated by the dryer 6 on one side.
[0048] Next, the billet located at the end of the lifting ramp 21 moves from the first transfer ramp 31 to the intermediate drying line 3. Specifically, the first transfer ramp 31 drops the billet and transports it to the beginning of the intermediate drying line 3. The intermediate drying line 3 drives the billet forward, so that the position of the intermediate drying line 3 is filled with billet one by one. During the filling process, the billet located on the intermediate drying line 3 is heat-dried by the dryer 6 on one side.
[0049] Next, the billet at the end of the middle drying line 3 moves from the second transfer ramp 41 to the bottom drying line 4. Specifically, the second transfer ramp 41 drops the billet and transports it to the beginning of the bottom drying line 4. The bottom drying line 4 drives the billet forward, so that the position of the bottom drying line 4 is filled with billet one by one. During the filling process, the billet on the bottom drying line 4 is heat-dried by the dryer 6 on one side.
[0050] Finally, the billet at the end of the bottom drying line 4 moves from the third transfer ramp 51 to the unloading area 5. Specifically, the third transfer ramp 51 drops the billet and transports it to the unloading area 5. The corresponding robotic arm on one side of the unloading area 5 picks up and transfers the billet at the very end to avoid billet accumulation.
[0051] With the above structure, the drying line layout method of multi-layer arrangement and step-down layering can reduce the floor space occupied by the drying line, improve drying efficiency, and increase the density of billet placement. Specifically, in this utility model, the billet is concentrated and lifted to the top drying line 2 in one go by the lifting ramp 21, and the top drying line 2 is filled with billet. After it is filled, the middle layer drying line 3 below the top drying line 2 is filled step by step until the bottom drying line 4 is finally filled. The dried billet at the end of the bottom drying line 4 is collected and taken out from the unloading area 5, realizing a multi-level arrangement with good space utilization.
[0052] This invention is particularly suitable for drying turbine housings with low vertical height. Therefore, it can make full use of the vertical height and expand the drying capacity of the production line as much as possible without increasing the floor space.
[0053] Furthermore, the lifting ramp 21 gradually rises from the material discharge area 1 towards the starting end of the top drying line 2. In fact, in this embodiment, the lifting ramp 21 is configured as a large, sloping ramp that spans all levels.
[0054] Furthermore, the feeding area 1 and the unloading area 5 are located at opposite ends on the same side of the shell-making and drying line. That is... Figure 2-3 The lower side is an area where operators can move freely, thus facilitating the movement of the robotic arm and enabling operators to perform quick maintenance operations on the feeding area 1 and the unloading area 5.
[0055] In this embodiment, the middle sections of the top drying line 2, the middle drying line 3, and the bottom drying line 4 are serpentine in the horizontal direction. Simultaneously, the turning points of the serpentine winding of the top drying line 2, the middle drying line 3, and the bottom drying line 4 are located on the side where the material discharge area 1 and the unloading area 5 are located, or on the side away from the material discharge area 1 and the unloading area 5. For example... Figure 2-4 As shown, its serpentine curve design places the longest middle section vertically along the vertical direction of the drawing, and turns 180 degrees at both the top and bottom ends of the drawing, forming an arc-shaped curve, which facilitates the arrangement of the track.
[0056] Specifically, the top drying line 2, the middle drying line 3, and the bottom drying line 4 are arranged to overlap each other along the horizontal direction, thus minimizing the floor space occupied by the shell-making drying line in this utility model.
[0057] Furthermore, the vertical gap height between the top drying line 2, the middle drying line 3, and the bottom drying line 4 is equal. The aforementioned height refers to the vertical gap height between two layers, which allows the billet to obtain uniform heat dissipation space and minimizes the overall structure height while avoiding collisions.
[0058] In another embodiment, the intermediate drying lines 3 are arranged in multiple layers, with each layer of intermediate drying lines 3 spaced vertically between the top drying line 2 and the bottom drying line 4. For example, when there are two intermediate drying lines 3, the total number of drying lines in this embodiment is four, which allows for a longer drying path and helps meet the needs of longer drying scenarios.
