Description

Technical Field

[0001] The utility model relates to the technical field of cold rolling mills, and in particular to a plate surface spraying device for a cold rolling mill with good cooling effect. Background Art

[0002] The cold rolling mill is a new type of steel bar cold rolling processing equipment, which is mainly used to process hot-rolled wire rods or hot-rolled coils into finished cold-rolled ribbed steel bars with a diameter of 5 mm to 12 mm. The cold rolling mill has been widely used in the steel industry and can produce high-strength, high-quality steel plates for use in construction, automobiles, ships and other fields.

[0003] The prior art has a patent number of CN220195950U for a cooling spray structure for a cold rolling mill. The patent relates to a cooling spray structure for a cold rolling mill, which includes a base, a cold rolling device body, a support frame and a spray mechanism. The spray mechanism is mounted on the support frame through a fixed frame and is equipped with a threaded rod and a movable block driven by a driving motor. The spray mechanism transports coolant to the water outlet pipe through a water inlet pipe, and the coolant is sprayed evenly by a nozzle to cool the steel pipe efficiently and evenly. The driving motor drives the water outlet pipe to swing back and forth to increase the water spraying area and improve the cooling effect. The overall design is practical and enhances the cooling efficiency and uniformity.

[0004] However, this patent uses a motor to drive the spray equipment, repeatedly rotating forward and reverse to achieve the swing of the spray plate. Although this method can achieve the desired effect, the motor needs to consume a lot of electrical energy to switch between forward and reverse rotation, which not only increases power consumption, but may also cause the equipment to generate additional heat during operation, requiring regular maintenance, which also increases the cost of use.

A plurality of circumferentially uniformly distributed fan blades 6 are fixedly sleeved on the outer circumference of the driving shaft 5. Through the arrangement of structures such as the driving gear 14 and the fan blades 6, the water flow drives the fan blades 6 to rotate, thereby realizing the rotation of the driving shaft 5, and then through the reciprocating swing of the sector tooth plate 15, the driving gear 14 is reciprocated to rotate, thereby realizing the reciprocating rotation of the spray shaft 8 and the swing. There is no need to use a separate power system for driving, which saves costs. The swing of the spray plate 9 realizes the comprehensive spraying of the spray head 10, making the spraying efficiency higher.
