Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for forging production, specifically to a heat treatment device for forging production. Background Technology

[0002] Heat treatment processes for forgings (such as normalizing and quenching) are crucial for improving the mechanical properties of forgings. Precise control of the quenching process plays a decisive role in the material's hardness, toughness, and other indicators. Traditional forging heat treatment processes typically employ a separate equipment layout, with the heat treatment furnace and quenching tank independently set up. Transferring high-temperature forgings requires manual labor or hoisting equipment. This approach has significant drawbacks. First, manual operation in a high-temperature environment poses serious safety hazards, as operators are susceptible to radiant heat injury. Second, the exposure time of forgings during transfer is difficult to control precisely, leading to accelerated surface oxidation and uneven temperature fields, affecting the consistency of quenching quality. Therefore, we propose a heat treatment device for forging production to address these problems. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This heat treatment device for forging production, equipped with a servo motor, threaded rods, connecting rods, hinged rods, and a placement plate, enables the servo motor to start, driving two threaded rods to rotate synchronously via a synchronous pulley and belt. The sliding block moves horizontally to the left under the drive of the threaded rods, pushing the placement plate along the support guide rail towards the quenching tank via the connecting rods and hinged rods. Under the action of gravity and the hinged rods, the placement plate automatically tilts, immersing the forging in the quenching tank for quenching. This avoids the need for operators to work in a high-temperature environment, thus preventing potential injuries.

[0013] 2. This heat treatment device for forging production, equipped with a servo motor, threaded rods, connecting rods, hinged rods, a placement plate, and a quenching tank, enables the servo motor to start. The servo motor drives two threaded rods to rotate synchronously via a synchronous pulley and belt. A sliding block moves horizontally to the left under the influence of the threaded rods. The connecting rods and hinged rods push the placement plate along the support guide rail towards the quenching tank. The servo motor's speed can be controlled, ensuring the placement plate enters the quenching tank within a specified time for quenching. Precise control of the forging exposure time during transfer is possible, improving quenching quality. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 The heat treatment equipment for forging production mainly consists of the following main components:

[0020] Forging heat treatment furnace 1: The furnace body is lined with high-temperature resistant ceramic fiber and equipped with electric heating elements or gas heating system.

[0021] Furnace door 12: Made of high-temperature resistant alloy, its lifting and lowering are controlled by winches on the two side support frames 11. The steel cable 13 is made of stainless steel, which makes the furnace door 12 open and close smoothly.

[0022] Support rail 2: extends from the forging heat treatment furnace 1 to the quenching pool 3. One section of the forging heat treatment furnace 1 is a horizontal rail, and the section of the quenching pool 3 is designed as an inclined rail of about 15°. The surface of the inclined section is coated with an anti-oxidation coating.

[0023] Quenching pool 3: The pool body is welded from stainless steel and filled with water-based or oil-based quenching medium. A liquid level sensor and a temperature controller can also be installed in the pool.

[0024] Placement plate 5: A placement slot is provided at the top, in which forgings can be placed. A baffle 51 is welded on the right side to balance the flow resistance of the quenching medium.

[0025] Servo motor 32: Installed on the right side of quenching tank 3, it drives the threaded rod 35 to rotate through synchronous pulley 34 and synchronous belt 31.

[0026] Threaded rod 35: Two threaded rods 35 are arranged in parallel on the top of the quenching tank 3, and the synchronous rotation of the two screws is achieved by the synchronous pulley 34 and the synchronous belt 31.

[0027] Sliding block 36: The bottom is embedded with a linear guide rail, the internal threaded hole matches the threaded rod 35, and the sliding stroke corresponds to the length of the support guide rail 2.

[0028] Hinged rod 52 and connecting rod 4: The hinged rod 52 and the two sides of the shelf 5 are hinged together. The hinged rod 52 is hinged to the connecting rod 4. The connecting rod 4 and the sliding block 36 are fixedly connected, which can realize the translation and tilting of the shelf 5.

[0029] Working principle: When the device is in use, the operator places the forging in the placement slot of the placement plate 5.

[0030] Start the winch, and the steel cable 13 pulls the furnace door 12 up to the open position. The placement plate 5 is pushed into the forging heat treatment furnace 1 through the support guide rail 2. After the furnace door 12 is closed, heating begins.

[0031] After heating is complete, the servo motor 32 starts and drives the two threaded rods 35 to rotate synchronously through the synchronous pulley 34 and the synchronous belt 31.

[0032] The sliding block 36 moves horizontally to the left under the drive of the threaded rod 35, and pushes the placement plate 5 to slide along the support guide rail 2 toward the quenching pool 3 through the connecting rod 4 and the hinge rod 52.

[0033] When the placement plate 5 enters the inclined section of the quenching pool 3, under the action of gravity and the hinge rod 52, the placement plate 5 automatically tilts and drives the forging into the quenching pool 3 for quenching. The through hole of the baffle 51 reduces the resistance to the flow of the medium and improves the uniformity of quenching.

[0034] After quenching, the servo motor 32 reverses, the sliding block 36 moves to the right, the placement plate 5 returns to the horizontal section inside the forging heat treatment furnace 1 along the inclined support rail 2, and the furnace door 12 opens again, completing one heat treatment cycle.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
