Description

Technical Field

[0001] This utility model relates to the field of steel casting processing technology, specifically to an annealing device for steel castings. Background Technology

[0002] Cast steel parts are parts made of cast steel. They have similar properties to cast iron, but are stronger. Cast steel parts are prone to defects such as porosity and inaccurate angular positioning during the casting process. Over long-term use, this can lead to housing breakage. Cast steel parts are one of the most widely used profiles in the field of machinery manufacturing.

[0003] After the steel plate casting is heated to a suitable temperature, it needs to be annealed. In the traditional technology, the steel plate casting is pushed into the annealing furnace for static cooling. However, the annealing time for the steel plate casting is relatively long and it is not convenient to anneal the steel plate casting evenly, resulting in poor flexibility.

[0004] Therefore, it is particularly important to improve existing annealing equipment for cast steel parts, design a new type of annealing equipment for cast steel parts to solve the above-mentioned technical defects, and improve the practicality of annealing equipment for overall cast steel parts. Utility Model Content

Through the overall design, the clamps are controlled to hold the cast steel parts, and then the fixed plate is driven to rotate, which facilitates uniform cooling and annealing, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An annealing device for cast steel parts includes a cabinet with a door hinged to the outside. A cooling fan is fixedly connected to the top of the cabinet.

[0008] As a preferred embodiment of this utility model, a track is fixedly connected between the collar and the fixed plate, and a baffle is fixedly connected to the outer side wall of the collar, the baffle having a semi-arc structure design.

[0010] As a preferred embodiment of this utility model, an arc-shaped plate is fixedly connected to the end of the swing rod away from the positioning column, and the arc-shaped plate is adapted to be used with the baffle.

[0011] As a preferred embodiment of this utility model, the gripper is provided in two sets, and a toothed gear is fixedly connected to one end of each set of grippers that is close to each other. The two sets of toothed gears are connected in an meshing manner, and a fixing plate is rotatably connected to the outer side of the toothed gear.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-5 This utility model provides a technical solution:

[0024] An annealing apparatus for cast steel parts includes a cabinet 1, with a cabinet door 2 hinged to the outside of the cabinet 1. A cooling fan 3 is fixedly connected to the top of the cabinet 1. Ventilation holes 4 are symmetrically provided on the outer side of the cabinet 1. A shaft 5 is rotatably connected to the left end of the inner side of the cabinet 1. A drive gear 6 is fixedly connected to the outside of the shaft 5. A driven gear 7 is meshed with the outside of the drive gear 6. A fixed plate 8 is rotatably connected to the end of the shaft 5 away from the drive gear 6. A collar 9 is fixedly connected to the outside of the fixed plate 8. A... The clamp 10 is used to place the cabinet 1 in a designated position and open the cabinet door 2. Then, the square plate-shaped cast steel part is placed inside the clamp 10. The cooling fan 3 is then driven to generate cold air inside the cabinet 1. The cold air is then blown onto the square plate-shaped cast steel part to cool it down. The heat dissipation holes 4 enable convection between the cabinet 1 and the outside environment, which facilitates annealing. Then, the collar 9 is rotated, which in turn causes the clamp 10 to rotate, so that each surface of the cast steel part can be cooled and annealed evenly.

[0025] Furthermore, in this embodiment, a track 11 is fixedly connected between the collar 9 and the fixed disk 8. A baffle 12 is fixedly connected to the outer wall of the collar 9. The baffle 12 has a semi-arc structure design. A fixed shaft 13 is fixedly connected inside the driven gear 7. A swing rod 14 is fixedly connected to the outside of the fixed shaft 13. A positioning post 15 is fixedly connected to one end of the swing rod 14. The positioning post 15 extends into the interior of the track 11 and is connected to the insertion shaft 5 through the output end of the motor. Then, the insertion shaft 5 rotates, causing the drive gear 6 to rotate and mesh with the driven gear 7, so that the driven gear 7 rotates. Then, the fixed shaft 13 rotates synchronously. Then, the rotational force is transmitted to the swing rod 14 to rotate. Then, the positioning post 15 will insert into the interior of the track 11 and squeeze the inner wall of the track 11, so that the collar 9 rotates a quarter turn. When the operation is repeated, the collar 9 will rotate a full turn. At the same time, the speed of the motor is controlled to realize the intermittent rotation of the collar 9, so that each surface of the cast steel part can be uniformly cooled and annealed.

[0026] Furthermore, in this embodiment, an arc-shaped plate 16 is fixedly connected to the end of the swing rod 14 away from the positioning post 15. The arc-shaped plate 16 is adapted to the baffle 12. When the swing rod 14 rotates, the arc-shaped plate 16 will move in contact with the baffle 12.

[0027] Furthermore, in this embodiment, the gripper 10 is provided in two sets. A toothed gear 17 is fixedly connected to the end of each set of grippers 10 that is close to each other, and the two sets of toothed gears 17 are connected in a meshing manner. A fixing plate 18 is rotatably connected to the outer side of the toothed gear 17. A synchronization plate 19 is fixedly connected to the top and bottom ends of the gripper 10. A synchronization rod 20 is fixedly connected to the middle of the gripper 10. An auxiliary gripper 21 is fixedly connected to the outside of the synchronization rod 20. A groove 22 is formed on the outside of the gripper 10 and the auxiliary gripper 21. The groove 22 has a wave-shaped structure design. A turntable 23, a fixing plate 18, and grippers 10 are rotatably connected to the left side inside the cabinet 1. The components are provided in two sets. The other set of fixed plates 18 and grippers 10 are fixedly connected to the turntable 23. By connecting the output end of the motor to one set of toothed gears 17, the two sets of toothed gears 17 mesh with each other, thereby making the upper and lower sets of grippers 10 move closer to each other and continuously reduce the distance between them to adapt to cast steel parts of different thicknesses. At the same time, when the grippers 10 move closer to each other, the auxiliary gripper 21 moves synchronously through the synchronous plate 19 and the synchronous rod 20 to increase the contact area with the cast steel parts. Meanwhile, the design of the groove 22 will increase the contact point with the cast steel parts, effectively preventing the grippers 10 from falling off when clamping the cast steel parts.

[0028] In this embodiment, the specific implementation scenario is as follows: The cabinet 1 is placed in a designated position, and the cabinet door 2 is opened. Then, a square-plate cast steel part is placed inside the gripper 10. The output end of the motor is connected to one set of toothed gears 17, causing the two sets of toothed gears 17 to mesh. This causes the upper and lower grippers 10 to move closer together, continuously reducing the distance between them to accommodate cast steel parts of different thicknesses. Simultaneously, as the grippers 10 move closer together, the auxiliary gripper 21 moves synchronously via the synchronization plate 19 and synchronization rod 20, increasing the contact area with the cast steel part. The design of the groove 22 further increases the contact point with the cast steel part, effectively preventing the grippers 10 from falling off during clamping. The motor output end is connected to the insertion shaft 5. Then, the insert shaft 5 rotates, causing the drive gear 6 to rotate and mesh with the driven gear 7, thus rotating the driven gear 7. This causes the fixed shaft 13 to rotate synchronously, and then the rotational force is transmitted to the swing rod 14 to rotate. Subsequently, the positioning pin 15 is inserted into the interior of the track 11 and squeezes the inner wall of the track 11, causing the collar 9 to rotate a quarter turn. Repeated operation will cause the collar 9 to rotate a full turn. At the same time, the speed of the motor is controlled to achieve intermittent rotation of the collar 9, which then drives the cooling fan 3 to generate cold air inside the cabinet 1. The cold air is then blown onto the square plate-shaped cast steel parts to cool them down. Through the heat dissipation holes 4, convection is formed between the cabinet 1 and the outside, so that each surface of the cast steel parts can be cooled and annealed evenly.

[0029] 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.
