Technical Field

[0001] The utility model relates to the field of steel ball rolling mills, in particular to a novel rolling mill for rolling balls and segments. Background Art

[0002] A steel ball mill is a machine specifically designed for producing steel balls. Its working principle relies on two intersecting rollers, which rotate and advance the workpiece through the friction between the rollers and the workpiece. This rolling process is also known as spiral rolling. The materials rolled are usually medium carbon steel, low-grade steel, and medium alloy steel.

[0003] The rolling mills in the prior art can only roll steel balls of fixed sizes. When there are demands for various sizes, only new production lines can be added, which greatly increases the cost. The present invention solves the above problem. Utility Model Content

[0004] In order to solve the technical problem that the rolling mill in the prior art can only roll steel balls of fixed sizes, and when there are requirements for multiple sizes, only new production lines can be added, which greatly increases the cost, the utility model provides a new rolling mill for rolling balls and segments.

[0005] A new rolling mill for rolling balls and sections includes: a rolling box with an electric heating element installed inside, two groups of spiral roller groups of different sizes rotatably connected to the inner wall of the rolling box, a steel bar hole of corresponding size is opened on the side wall of the rolling box in the middle of the spiral roller group, baffles are provided on both sides of the spiral roller group, each roller shaft end of the spiral roller group is connected to a gear 1, the upper or lower two gears 1 of adjacent spiral roller groups are meshed and connected by a gear 2, the gear 2 is detachable, and the power is connected to the spiral roller group through two universal joint transmission shafts.

[0006] Furthermore, the adjacent spiral roller groups share the same baffle, and both sides of the baffle are concave, and the concave diameter is equal to and coincides with the center of the steel ball.

[0007] Furthermore, a ball outlet hole is opened at the lower part of the side wall opposite to the steel bar hole on the rolling box. The ball outlet hole is located at the lowest point of the curved surface on the guide plate. The guide plate is arranged at the lower part of the extrusion end of the spiral rolling roller group, and the guide plate is connected to the inner wall of the rolling box.

[0008] Furthermore, the gear 1 and the gear 2 are both located outside the rolling box.

[0009] Beneficial effects of the utility model:

[0010] Two sets of spiral rollers of different sizes are added in the rolling box. The adjacent spiral rollers are connected by three gears to ensure that the rollers rotate, roll and convey in the same direction.

[0011] When a single spiral roller group is required to work, remove gear 2 and connect the two universal joint drive shafts to the other spiral roller group to complete the switch. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is achieved by performing activities on connecting parts such as hinges, pins and short shafts.

[0018] The present invention will be described in detail below with reference to the accompanying drawings. Example

[0019] The following is combined with Figure 1-3 This embodiment describes a novel rolling mill for rolling balls and segments, comprising: a rolling box 1, wherein an electric heating element is provided in the rolling box 1, wherein two groups of spiral roller groups 2 of different sizes are rotatably connected to the inner wall of the rolling box 1, wherein a steel bar hole 3 of corresponding size is opened on the side wall of the rolling box 1 in the middle of the spiral roller group 2, and baffles 4 are provided on both sides of the spiral roller group 2, wherein each roller shaft end of the spiral roller group 2 is connected to a gear 1 5, and the upper or lower two gears 1 5 of adjacent spiral roller groups 2 are meshed and connected via a gear 2 6, and the gear 2 6 is detachable. The power is connected to the spiral roller group 2 via two universal joint transmission shafts;

[0020] Insert the red-hot steel bars of corresponding sizes into the corresponding steel bar holes 3, and the power drives a set of spiral roller groups 2 to rotate through two universal joint transmission shafts to roll the steel bars into balls. The roller shaft ends of the spiral roller group 2 are engaged through two gears 1 5 and one gear 2 6 to drive the adjacent spiral roller groups 2 to rotate in the same direction to roll steel bars of another size into balls, thereby realizing the production of steel balls of different sizes by the same equipment. When only the other set of spiral roller group 2 is working, remove gear 2 6, remove the two universal joint transmission shafts and connect them to the shaft ends of the other set of spiral roller group 2.

[0021] Adjacent spiral roller groups 2 share the same baffle 4, with both sides of the baffle 4 being concave, with the concave diameter and the center of the circle being equal to and coinciding with the steel ball;

[0022] While guiding the steel bars, shape the steel balls.

[0023] A ball outlet hole 7 is provided at the lower portion of the side wall opposite to the steel bar hole 3 on the rolling box 1. The ball outlet hole 7 is located at the lowest point of the upper curved surface of the guide plate 8. The guide plate 8 is provided at the lower portion of the extrusion end of the spiral roller group 2 and is connected to the inner wall of the rolling box 1.

[0024] The steel balls squeezed out by the two spiral roller groups 2 fall onto the guide plate 8 and slide along the curved surface of the guide plate 8 to the ball outlet hole 7 for discharge.

[0025] Gear 1 5 and gear 2 6 are both located outside the rolling box 1;

[0026] Prevent continuous high temperature from affecting the quality of gear 1 5 and gear 2 6.
