Description

Technical Field

[0001] This utility model belongs to the field of vacuum heat treatment technology, specifically relating to a vacuum heat treatment system for high-purity silicon carbide ceramic components. Background Technology

[0002] Silicon carbide ceramics are advanced ceramic materials containing silicon and carbon, possessing excellent mechanical properties at both room temperature and high temperature. In the process of processing silicon carbide ceramics, in order to improve their performance and structure, it is usually necessary to perform heat treatment on the ceramic parts, which involves the use of a vacuum heat treatment system.

[0003] Currently, after heat treatment of silicon carbide ceramic components, operators usually need to manually remove the placement plate containing the ceramic components from the heat treatment furnace. However, due to the high temperature inside the furnace, the conductive furnace body can easily burn the operator's hands, which is detrimental to the operator's health. Furthermore, it is difficult to quickly remove the silicon carbide ceramic components, reducing the convenience of the vacuum heat treatment system. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum heat treatment system for high-purity silicon carbide ceramic components, in order to solve the problem that existing vacuum heat treatment systems are difficult to remove silicon carbide ceramic components quickly, thus reducing the convenience of the vacuum heat treatment system.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum heat treatment system for high-purity silicon carbide ceramic components, comprising: a furnace body, with support legs connected to the bottom of the furnace body and a furnace door rotatably connected to one side of the furnace body, a quenching motor installed on one side of the furnace door, and a vacuum pump and a safety valve installed on the top of the furnace body; an automatic push-pull assembly, the automatic push-pull assembly being disposed inside the furnace body, the automatic push-pull assembly including connecting blocks, two connecting blocks symmetrically connected to the inner wall of the furnace body, a baffle provided on the inner wall of the furnace body, one side of each of the two connecting blocks being connected to one side of the baffle, and a sliding groove being opened on the top of each of the two connecting blocks, a screw being rotatably connected to one side of the inner wall of one of the sliding grooves via a bearing, one end of the screw penetrating through one side of the baffle, a motor being installed on one side of the baffle, the output ends of the motors being interconnected, sliders being slidably connected inside each of the two sliding grooves, the screw and the slider being threadedly connected, a mating block being connected to the top of each of the two sliders, and a placement plate being connected between the two mating blocks.

[0006] Preferably, a disassembly assembly is provided between the placement plate and the docking block. The disassembly assembly includes a docking block, two docking blocks are respectively connected to both sides of the placement plate, a docking groove matching the docking block is opened on one side of the top of the docking block, an insertion hole is opened on one side of the inner wall of the docking groove, and an insertion rod matching the insertion hole passes through the docking plate.

[0007] Preferably, the top of the placement plate has a groove, and one side of the inner wall of the groove has multiple through holes.

[0008] Preferably, each of the two connecting blocks has a support block connected to one side of its opposite side.

[0009] Preferably, a guide rod is connected between the inner walls of the two sides of one of the grooves, and the guide rod passes through the slider.

[0010] Preferably, a pull ring is connected to the top end of the insertion rod.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] (1) By setting up an automatic push-pull assembly, the motor is turned on, and the motor drives the screw to rotate through the bearing. Since the screw and the slider are connected by threads, the screw drives the placement plate to move on the two connecting blocks through the slider and the docking block, so that the placement plate moves to the outside of the furnace body. There is no need for the operator to manually pull out the placement plate, which avoids burns to the operator's hands and allows for quick removal of silicon carbide ceramic parts, thus improving the convenience of the vacuum heat treatment system.

[0013] (2) By setting up a disassembly and assembly component, when it is necessary to separate the placement plate from the docking block, the insertion rod is pulled upward to move the insertion rod upward and make one end of the insertion rod disengage from the insertion hole, so that the docking plate is released from the limit on the docking groove and the placement plate is pulled outward to separate the placement plate from the docking block. This realizes the rapid separation of the placement plate from the docking block, improves the disassembly and assembly efficiency of the placement plate, facilitates the uniform removal of ceramic parts on the placement plate, and is beneficial to the operator.
