Description

Technical Field

[0001] This invention mainly relates to the field of casting production, and specifically to a spray drying device for precision castings. Background Technology

[0002] Precision casting refers to the general term for the process of obtaining castings with precise dimensions. It is a metal shaped object obtained by various casting methods. Compared with the traditional sand casting process, precision casting produces castings with more accurate dimensions and better surface finish. It mainly includes: investment casting, ceramic mold casting, metal mold casting, pressure casting, and lost foam casting.

[0003] In the invention patent application CN202110896875.4, published on November 1, 2022, entitled "A Spraying and Drying Device for Precision Castings", the device includes a base with a housing at its upper end. A fixing rod is mounted on the top of the housing, and a cylinder is sleeved on the fixing rod. A spraying mechanism and a drying mechanism are mounted on the cylinder. The spraying mechanism is used to spray the precision castings, and the drying mechanism is used to dry the sprayed precision castings. A fixing plate is horizontally positioned in the middle of the housing, and a fixing sleeve is mounted on the fixing plate, penetrating the fixing plate. A rotating rod is mounted inside the fixing sleeve, and a lifting plate is mounted on the upper end of the rotating rod for placing the precision castings. This device does not dry and harden the atomizing nozzles on the drying mechanism, and the nozzles will not be blocked. The spraying and drying mechanisms do not interfere with each other and can work sequentially within the same housing without the need for separate drying treatment. The operation is simple, convenient, and highly efficient.

[0004] However, the above-mentioned processing equipment has the following drawbacks in actual use: the precision castings need to be sprayed and dried separately, which results in a large overall weight of the equipment and cannot adjust the shape of the precision castings during the spraying and drying process, resulting in poor spraying and drying effects. Summary of the Invention

[0005] 1. The technical problem that the invention aims to solve: The present invention provides a spray drying apparatus for precision castings to solve the technical problems existing in the background art.

[0006] 2.

[0007] Furthermore, the suspension adjustment frame forms a sliding structure on the surface of the drying spray box via a rotating motor, and the suspension adjustment frame forms a swinging structure inside the drying spray box.

[0008] Furthermore, the drying spray box includes an outer box, a slot is provided at the top of the outer box, pulley tracks are provided on both sides of the slot, a spraying chamber is provided on one side of the inner wall of the outer box, and a drying chamber is provided on one side of the spraying chamber.

[0009] Furthermore, both the spraying chamber and the drying chamber are located inside the outer casing, and the surface of the spraying chamber is equipped with spray nozzles.

[0010] Furthermore, the suspension adjustment frame includes a rotating lead screw, a sliding platform is provided on the surface of the rotating lead screw, a swing arm is movably connected to the upper surface of the sliding platform, a swing support plate is provided on the surface of the sliding platform, a hydraulic cylinder base is provided on the upper surface of the sliding platform, a telescopic hydraulic cylinder is provided between the hydraulic cylinder base and the swing arm, and a sliding wheel is provided at the lower end of the sliding platform.

[0011] Furthermore, the rotating lead screw and the rotating motor constitute a transmission structure, the sliding platform forms a sliding structure on the pulley track surface through the rotation of the rotating lead screw, the swing arm forms a swing structure through the telescopic hydraulic cylinder, and one end of the swing support plate is movably connected to the surface of the swing mounting frame.

[0012] Furthermore, the swing mounting bracket includes an outer swing shell, an embedded sliding groove is provided on the inner wall surface of the outer swing shell, a telescopic toothed handle is slidably connected to the surface of the embedded sliding groove, a return spring is provided on the rear end surface of the telescopic toothed handle, and a half-tooth gear is provided on one side surface of the telescopic toothed handle.

[0013] Furthermore, a motor output end is connected to the upper part of the half gear, and two telescopic toothed handles are provided, respectively located on the two sides of the half gear. The telescopic toothed handles form a reciprocating telescopic structure through the half gear on the inner sliding groove surface. The front part of the telescopic toothed handle is provided with a slot for installing a precision casting. The two telescopic toothed handles reciprocate to drive the precision casting to swing on the inner surface of the drying spray box.

[0014] 3. Beneficial effects: This invention is rationally designed. During installation, the precision casting is mounted on one side of the swing arm of the suspension adjustment frame. Simultaneously, the telescopic cylinder in the suspension adjustment frame is activated, causing the telescopic cylinder to swing the swing arm downwards. This swing arm then lowers the mounting frame and the precision casting into the spray chamber inside the drying spray box. Spraying is then performed through the nozzle inside the spray chamber. During this process, the half-tooth gear in the swing mounting frame rotates, causing the two telescopic toothed handles to reciprocate, thereby causing the precision casting at its front end to swing left and right, resulting in a better spraying effect. After the spraying operation is completed, the rotating motor is started to drive the rotating screw at the lower end of the sliding platform to rotate. At the same time, the sliding platform slides on the surface of the pulley track, moving the suspension adjustment frame and the swing mounting frame from the spraying chamber in the drying spray box to the drying chamber, thereby achieving the purpose of reducing the equipment footprint and usable area.

[0021] See attached document Figure 1-6 The device includes a drying spray box 1, with a placement platform 2 on some surfaces of the drying spray box 1. A rotating motor 3 is installed on one side surface of the drying spray box 1. A suspension adjustment frame 4 is movably connected to the upper surface of the drying spray box 1. A swing mounting frame 5 is movably connected to one end surface of the suspension adjustment frame 4. A side-opening door 6 is installed on one side surface of the drying spray box 1. A support leg 7 is installed below the drying spray box 1. The suspension adjustment frame 4 forms a sliding structure on the surface of the drying spray box 1 through the rotating motor 3. The suspension adjustment frame 4 forms a swing structure inside the drying spray box 1. This device realizes the movement and on-table adjustment of precision castings through the suspension adjustment frame 4.

[0022] The drying spray box 1 includes an outer casing 101. A slot 102 is provided at the top of the outer casing 101, and pulley tracks 103 are provided on both sides of the slot 102. A spraying chamber 104 is provided on one side of the inner wall of the outer casing 101, and a drying chamber 105 is provided on one side of the spraying chamber 104. Both the spraying chamber 104 and the drying chamber 105 are located inside the outer casing 101. A spray nozzle is provided on the surface of the spraying chamber 104. The suspension adjustment frame 4 includes a rotating screw 401, and a sliding platform 402 is provided on the surface of the rotating screw 401. A swing arm 403 is movably connected to the upper surface of the sliding platform 402. The sliding platform 402 has a swing support plate 404 on its surface, a cylinder base 405 on its upper surface, a telescopic cylinder 406 between the cylinder base 405 and the swing arm 403, a sliding wheel 407 at its lower end, a rotating screw 401 and a rotating motor 3 forming a transmission structure, the sliding platform 402 forming a sliding structure on the surface of the pulley track 103 through the rotation of the rotating screw 401, the swing arm 403 forming a swing structure through the telescopic cylinder 406, and one end of the swing support plate 404 being movably connected to the surface of the swing mounting frame 5.

[0023] In this embodiment, during installation, the precision casting is installed on one side of the swing arm 403 of the suspension adjustment frame 4. At the same time, the telescopic cylinder 406 in the suspension adjustment frame 4 is activated, causing the telescopic cylinder 406 to drive the swing arm 403 to swing downwards. The swing arm 403 then drives the mounting frame 5 and the precision casting to fall into the spray chamber 104 inside the drying spray box 1. Spraying is then performed through the nozzle inside the spray chamber 104. During this process, the half-tooth gear 505 in the swing mounting frame 5 rotates, causing the two telescopic toothed handles 503 to reciprocate, thereby causing the precision casting at its front end to swing left and right, resulting in a better spraying effect.

[0024] The swing mounting bracket 5 includes an outer swing shell 501. The inner wall surface of the outer swing shell 501 is provided with an embedded sliding groove 502. A telescopic toothed handle 503 is slidably connected to the surface of the embedded sliding groove 502. A return spring 504 is provided on the rear end surface of the telescopic toothed handle 503. A half-tooth gear 505 is provided on one side surface of the telescopic toothed handle 503. A motor output end is connected to the upper part of the half-tooth gear 505. There are two telescopic toothed handles 503, which are respectively provided on the two sides of the half-tooth gear 505. The telescopic toothed handles 503 form a reciprocating telescopic structure on the surface of the embedded sliding groove 502 through the half-tooth gear 505. The front end of the telescopic toothed handle 503 is provided with a slot for installing a precision casting. The reciprocating telescopic structure of the two telescopic toothed handles 503 drives the precision casting to swing on the inner surface of the drying spray box 1.

[0025] In this embodiment, after the spraying operation is completed, the rotating motor 3 is started to drive the rotating screw 401 at the lower end of the sliding platform 402 to rotate, and at the same time, the sliding platform 402 slides on the surface of the pulley track 103, moving the suspension adjustment frame 4 and the swing mounting frame 5 from the spraying chamber 104 in the drying spray box 1 to the inside of the drying chamber 105, thereby achieving the purpose of reducing the equipment footprint and usable area.
