Description

Stress relief aging furnace for martensitic stainless steel castings Technical Field The utility model relates to the technical field of stress relief of stainless steel castings, in particular to a stress relief aging furnace for martensitic stainless steel castings. Background In the production and processing process of martensitic stainless steel castings, stress relief is needed to be carried out on the castings by using an ageing furnace so as to ensure that the quality of the produced stainless steel castings can meet the production requirements. When the prior art works, partial oxidation can occur on the surface of the stainless steel casting at high temperature, dust accumulation in a hearth can be caused by long-term operation of the aging furnace, if accumulated dust flies on the stainless steel casting, the follow-up stress relief work can be influenced, workers are required to spend time to clean the stainless steel casting in the later period, residual heat still exists on the inner wall of the furnace and the casting when the casting subjected to stress relief is discharged, and the workers stretch into the hearth, so that the situation of scalding can occur. Disclosure of utility model Aiming at the defects of the prior art, the application provides a stress relief aging furnace for martensitic stainless steel castings. According to the stress relief aging furnace for martensitic stainless steel castings, through the structural design of the ash removal component, the effect of removing ash on the inner wall surface of the enclosure cavity is achieved while the castings are pushed to be separated from the enclosure cavity, and the castings with residual heat are cooled again under the cooperation of the auxiliary component, so that the residual heat of the castings is prevented from scalding workers, and the accumulated ash is automatically extracted and cleaned. The technical scheme of the application is as follows: The utility model provides a martensite stainless steel foundry goods stress relief ageing furnace, includes the structure case, install sealed door plant on the casing of structure case, the structure case encloses with sealed door plant and closes the chamber, enclose and close chamber internally mounted and have the deashing subassembly, install auxiliary assembly on the structure case, including the slide rail in the deashing subassembly, enclose the inner wall bottom terminal surface symmetry position rigid coupling of closing the chamber and have the slide rail, two the removal chamber has all been seted up to the inside of slide rail, two the removal hole has all been seted up to the equal altitude position on the vertical structural plane that the slide rail kept away from each other, every the screw rod is all installed in the inside of removal chamber in the rotation, and the movable block is all installed to the inside of every removal chamber, the screw rod cross-section outside at corresponding position is established through the thread bush to the movable block, enclose and be provided with vertical scraper blade on closing chamber inner wall bottom terminal surface, the top rigid coupling of scraper blade has the scraping the movable frame, the tip of movable block passes the removal hole and connects on the board of scraper blade, the inside of keeping away from sealed door plant's the inside of structure case shell is kept away from each other and is installed the screw rod symmetry position and is connected with the inside of drive motor of the corresponding position. Compared with the prior art, through the combined operation of deashing subassembly and auxiliary assembly, the dust deposit that produces when accomplishing stress relief is scraped and is moved the clearance, accomplishes simultaneously to push out spacing slide fastener and layer board along the slide rail, breaks away from the in-process that encloses the chamber at the foundry goods, realizes cooling once more and clear up the effect of dust deposit, when guaranteeing staff's safety, can also accomplish to enclose and close the chamber inner wall face and carry out self-cleaning. In the stress relief aging furnace for martensitic stainless steel castings, the bottom end face of the scraping plate is attached to the bottom end face of the enclosing cavity, the edge of the structural hole formed in the bottom of the scraping plate is attached to the outer surface of the sliding rail, and the edge of the frame body of the scraping frame is attached to the inner wall face of the enclosing cavity. By adopting the structure, the dust deposit attached to the inner wall surface of the enclosing cavity and the outer surface of the sliding rail can be effectively scraped off, and the cleanliness of the inner wall surface of the enclosing cavity and the outer surface of the sliding rail can be ensured. In the stress relief aging furnace for martensitic stainless steel castings, the limiting grooves are
