Oil nozzle structure with oil coating

Abstract

The invention relates to a nozzle structure for daubing a material strap with oil. The nozzle structure comprises a nozzle body; the nozzle body is arranged above the material strap; the nozzle body is of a shell structure of which the upper end is large and the lower end is small; an oil pipe communicated with an oil tank is arranged at the outer side of the upper end of the nozzle body; the inner wall of nozzle body is obliquely and fixedly connected with an oil guide plate; the high end of the oil guide plate is provided with an arc-shaped oil guide area and located below the oil inlet of the oil pipe; a plurality of oil leak holes are evenly distributed in the oil guide plate; the lower end of the nozzle body is provided with an oil guide part bent to the conveying direction of the material strap; the oil guide part is provided with a falling oil groove. According to the nozzle structure disclosed by the invention, oil flow is evenly guided to drop to the oil guide part by the oil guide plate; the material strap is evenly daubed with oil drops by the oil guide part through the falling oil groove; the daubing evenness of the nozzle structure is high; the falling oil width is limited by the width of the falling oil groove, and therefore the condition that the oil drops drop out of the material strap to cause pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of stamping machinery and equipment, in particular to an oiling device for stamping strips. Background technique [0002] At present, when producing stamped products, it is necessary to spray stamping oil on the strip to facilitate stamping. In the prior art, the commonly used oil spraying methods basically include dripping, oiling, and spraying. The advantage of dripping operation is that its pollution is small, and the oil droplets will not drip to the outside of the material belt. Uneven application; during oiling operation, oil the upper and lower sides of the material belt after dipping a felt roller in oil. The material belt sprays the oil mist directly, which has the advantage of relatively uniform application, but the disadvantage is that the distance between the nozzle and the material belt is relatively large, and the oil mist spreads greatly during spraying, and the oil mist is not easy to adhere...
