Description

Technical Field

[0001] This utility model belongs to the field of metal matrix composite material manufacturing, and specifically relates to a metal composite plate casting device. Background Technology

[0002] Metal composite plates are made by combining two or more metal plates with different properties through special processing methods. By integrating the advantages of different metal components, the performance limitations of single materials can be overcome, resulting in superior physical and chemical properties and significantly improved overall performance. Common methods for preparing metal composite plates include explosive welding, rolling, explosive welding + rolling, liquid-solid phase composite, spray deposition, and vacuum hot pressing. Among these, explosive welding + rolling is a commonly used process for producing high-performance dissimilar metal layered composite thin plates due to its ability to achieve high interfacial bonding strength and good reprocessing performance.

[0003] However, the cost of using explosive welding to prepare blanks is very high, which limits the large-scale production of metal composite plates. In order to reduce the manufacturing cost of metal composite plates, it is urgent to develop a metal composite plate casting device. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and thus provide a metal composite plate casting device.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A metal composite plate casting apparatus includes a crucible, a sealing cap, a riser pipe, an air inlet pipe, and a mold. The crucible is fitted with a sealing cap and contains molten metal. An air inlet pipe is located on one side of the upper part of the crucible. The sealing cap is fitted with a riser pipe, one end of which is inserted into the crucible, and the other end is connected to the mold cavity. The mold includes an upper mold and a lower mold. Fixing blocks are respectively provided on the inner bottom middle two sides and the inner upper two side walls of the lower mold. The fixing blocks are provided with embedding grooves, and the width of the embedding grooves is consistent with the sum of the thicknesses of the two substrates.

[0006] Furthermore, the upper and lower molds are detachably connected by bolts.

[0007] Furthermore, one side of the substrate is flat, and the other side is corrugated.

[0008] The beneficial effects of this utility model are: This invention, through the integrated design of the crucible and mold, combined with the precise positioning structure of the fixed block embedding groove, enables the simultaneous molding of two metal composite plates in one operation, significantly improving production efficiency and reducing unit costs. The corrugated metal plate welding structure with the corrugated surface facing outwards, combined with a talc powder isolation layer, provides an optimized interface for subsequent rolling. The compressed air pressurized riser system ensures uniform coating of the molten metal within the mold cavity, forming a four-layer symmetrical composite structure. The fixed block and embedding groove within the lower mold fit tightly with the metal plate, ensuring the vertical stability and lateral fixation of the substrate during casting, guaranteeing the molding accuracy of the composite plate. Simultaneously, the embedding groove structure provides a pre-set welding area for missing material during casting, ensuring the integrity of the composite plate blank and providing efficient and stable hardware support for the large-scale production of metal composite plates.

Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be emphasized that the following description is exemplary and not intended to limit the scope and application of the present invention.

[0011] Example: Figure 1 and Figure 2As shown, the system includes a crucible 6, a sealing cap 5, a liquid riser 7, an air inlet pipe 9, and a mold. The crucible 6 is fitted with the sealing cap 5 and contains molten metal. An air inlet pipe 9 is located on one side of the upper part of the crucible 6. The sealing cap 5 has a liquid riser 7, one end of which is inserted into the crucible 6, and the other end communicates with the mold cavity. The mold consists of an upper mold 1 and a lower mold 3, which are detachably connected by bolts 2. Fixing blocks 4 are provided on the inner bottom center sides and the inner upper side walls of the lower mold 3. The fixing blocks 4 have embedding grooves 41, the width of which is equal to the sum of the thicknesses of the two substrates 8. In this invention, the fixing blocks 4 on the inner bottom center sides of the lower mold 3 support and position the lower edges of the two substrates 8, ensuring the vertical stability of the substrates in the mold cavity; the fixing blocks 4 on the side walls clamp and fix the sides of the two substrates 8, preventing displacement of the substrates during molten metal filling. Four fixing blocks 4, through the tight fit of the embedded grooves 41 with the substrate 8, together form an all-round fixation of the two substrates 8, so that they maintain the preset position during the casting process and ensure the molding accuracy of the composite plate. Under the action of compressed air, the molten metal enters the crucible 6 through the air inlet pipe 9 and is pressed into the casting cavity through the liquid riser pipe 7, so as to realize the one-time molding of two metal composite plates.

[0012] In this embodiment, one side of the substrate 8 is a flat surface, and the other side is a corrugated surface.

[0013] Taking the processing of two titanium-aluminum composite plates at one time as an example, the substrate 8 is made of TA1 pure titanium plate, and the molten metal is made of 2A12 aluminum alloy. The processing procedure of this utility model is as follows: 1. Material preparation: Tightly bond two TA1 pure titanium plates of the same size (apply a layer of talcum powder between the two pure titanium plates to prevent them from sticking together during subsequent large deformation rolling), weld the four edges of the TA1 pure titanium plates together (with the corrugated side facing outwards). 2. Surface cleaning: Remove surface impurities after welding; 3. Secure the cleaned sheet material inside the mold; 4. Low-pressure cladding casting: Compressed air is injected into crucible 6. Under the action of air pressure, the molten 2A12 aluminum alloy in crucible 6 is sent into the casting cavity through riser pipe 7 for low-pressure cladding casting to obtain a composite slab of 2A12 aluminum alloy layer-pure titanium layer-pure titanium layer-2A12 aluminum alloy layer. The relevant process parameters are: low-pressure casting temperature 720℃, pressure increase rate 5 kPa / s, holding pressure 0.07MPa (relative pressure), and holding time 300s. 5. Repair welding: After the low-pressure cladding casting is completed, the four small missing material areas on the composite slab corresponding to the embedded groove positions are repaired by welding with 2A12 aluminum alloy welding rods. 6. After welding, the composite slab is subjected to diffusion heat treatment and large deformation symmetrical hot stacking. Then, the edges of this set of rolled plates are trimmed, and finally, they are separated to obtain two titanium-aluminum composite plates.
