Description

Technical Field

[0001] This utility model relates to the technical field of steel ball forging and rolling equipment, specifically a double-helix steel ball waiting-to-heat conveying device. Background Technology

[0002] In the current steel ball forging and rolling industry, to obtain better uniformity and consistency in surface hardness and core hardness of the forged and rolled steel balls, the steel balls need to be cooled to a range suitable for the quenching process of the steel ball material after forging / rolling before quenching. However, in the current actual production process, a single spiral and roller pair are used for the warming and conveying of steel balls. Due to the large production volume of steel balls, the steel balls are pushed forward by the single-sided spiral and the roller pair during the warming and conveying process, which causes severe wear on the roller pair.

[0003] For the reasons mentioned above, severe wear of the roller assembly caused the steel balls to stop and jam during the upward conveying process. Under the continuous conveying action of the screw conveyor, the lower steel balls overlapped with the stopped and jammed ones, causing them to fall out of the conveyor. Since the steel balls are processed at around 1000 degrees Celsius, there are serious safety hazards for employees handling the fallen balls, as they are prone to burns and scalds. Furthermore, the steel balls that fall to the ground are often not noticed by employees in time, resulting in a temperature drop below the required process range. This necessitates secondary heating and quenching, wasting electricity, manpower, and natural gas, thus causing an invisible economic waste for the company.

[0004] Furthermore, because the steel ball conveyor relies on a specific angle formed between the single-sided spiral and the roller pair during the steel ball transport process, and due to the high production capacity of the shift, with approximately 16,000 large-diameter steel balls produced daily, the roller pair suffers severe wear due to the frictional transport of a large number of steel balls. The steel balls may become stuck on the conveyor, and when the wear is severe, the gap between the conveying spiral and the roller pair increases, causing the steel balls to fall directly off the conveyor. This necessitates production shutdowns for conveyor maintenance and roller pair replacement, disrupting normal production and causing various energy indicators to exceed the normal process cost quota, which is detrimental to the long-term development of the enterprise.

Holes are drilled in the lower part of both warming conveyor helices to cool the tube body, extending the service life of the helical conveyor shafts and reducing spare parts replacement costs for enterprises.

A first gear 8 and a second gear 9 are respectively installed at the top of the channel steel support 2 and at the top of the right-handed spiral 10 and the left-handed spiral 14. The first gear 8 and the second gear 9 are installed at right angles and mesh with each other. A V-belt 12 is wound around the surface of the first gear 8 and the second gear 9, and a pulley 11 is wound around the first gear 8 and the second gear 9 through the V-belt 12.

[0022] Furthermore, a motor speed reducer 13 is fixedly connected to the outer surface of the pulley 11, and the position of the motor speed reducer 13 is located on the outer side of the top surface of the channel steel bracket 2, which maximizes the control capability of the overall device and ensures the practicality of the overall device.

[0023] Furthermore, a bearing box 1 is installed on the lower surface of the channel steel bracket 2, and a wound round steel 3 is installed on the surface of the channel steel bracket 2 above the bearing box 1, which effectively enhances the stability of each component and strengthens the support of the overall device.

[0024] Furthermore, an oil drill pipe 4 is installed on the surface of the channel steel support 2 and on the outside of the right-hand spiral 10, and the top of the oil drill pipe 4 is provided with a ball outlet 5 on the surface of the channel steel support 2, which better protects the use of the overall device from being affected and enhances the practicality of operating the overall device.

[0025] Furthermore, the upper surface of the channel steel support 2 is provided with an inlet 15 and an outlet 5 at the upper and lower ends, respectively, and the inlet 15 and outlet 5 are arranged at a relative angle, which better enhances the balance of the overall device and effectively enhances the flexibility of the overall device.

[0026] Furthermore, heat dissipation holes 16 are provided on the outer surface of the bearing housing 1, which further enhances the operability of the overall device and ensures its robustness and stability during use.

[0027] Furthermore, a fixed bearing box 7 is installed on the top surface of the channel steel bracket 2 on the side opposite to the motor speed reduction belt 13, and a steel ball 6 is detachably connected inside the fixed bearing box 7, which maximizes the operator's control over the overall device, improves the user experience of the overall device, and reduces the difficulty of operation for the operator.

[0028] The usage method of this embodiment is as follows: When using it, please refer to... Figure 1-3 First, the conveying pitch is designed based on the diameter of the conveying steel ball 6. Then, using a template, the left-hand pitch of the left-hand helix 14 and the right-hand pitch of the right-hand helix 10 are laid out on the oil drill pipe 4. Next, along the lower ends of the left-hand helix 14 and right-hand helix 10, uniformly and symmetrically drill 3.2 mm diameter heat dissipation holes 16 on the oil drill pipe 4 using a bench drill or radial drill. These holes are used for ventilation and heat dissipation when the oil drill pipe 4 is conveying the high-temperature steel ball 6, preventing bending and deformation due to excessive heating. Thirty mm diameter wound round steel 3 is used during heating... In the current state, the conveying spiral is welded along the template line drawn on the oil drill pipe 4. Simultaneously, the bottom shaft of the oil drill pipe 4 is machined and welded using a lathe. During the upper shaft machining, one end of the spiral guide rod needs to be pre-diameterized and connected with a thin shaft for the ball ejection of the steel ball 6. The channel steel support 2 is welded according to the actual conveying height on site. The right-hand spiral 10 is installed on the left side of the channel steel support 2, and the left-hand spiral 14 is installed on the right side of the channel steel support 2, ensuring that the rotational leads of the right-hand spiral 10 and the left-hand spiral 14 correspond. The lower part is then fixed using the bearing box 1. The upper part... Based on the conveying distance between the two screw conveyors, the first gear 8 and the second gear 9 are selected and manufactured to ensure they have the same diameter and number of teeth, guaranteeing consistent rotational speed. During installation, the effective meshing distance of the first gear 8 and the second gear 9 is ensured for effective transmission. A fixed bearing housing 7 is used for installation and fixation. Finally, the pulley 11, V-belt 12, and reducer motor 13 are assembled and installed on the left-hand spiral 14. During production, the steel balls 6 to be processed enter the conveying angle between the two conveying screws through the ball track and inlet 15. 13 drives the left-hand spiral 14 to rotate to the right via the pulley 11, while the right-hand spiral 10 is driven to rotate to the left via the gear on the left-hand spiral 14. The conveying spiral also pushes the steel ball 6 forward, so that the two conveying spirals have different spiral directions and rotation directions, and at the same time, they have a forward pushing force on the steel ball 6 being conveyed, so that the steel ball 6 will not get stuck or stop on the conveying auger. When the steel ball 6 reaches the ball outlet 5 under the conveying action of the two spirals, the steel ball falls into the ball channel connected below, and the lower process of the steel ball 6 is performed.
