Adjustable spray head

Abstract

The invention relates to the technical field of spray heads, in particular to an adjustable spray head. The adjustable spray head comprises an inner ring support, an outer ring support, multiple leadscrew assemblies and multiple nozzles, wherein the inner ring support and the outer ring support are arranged concentrically. The multiple lead screw assemblies are arranged between the inner ring support and the outer ring support in a spaced manner in the circumferential direction; each lead screw assembly comprises a lead screw rod and a lead screw nut, wherein each lead screw nut is arranged on the corresponding lead screw rod and performs axial reciprocating motion along the corresponding lead screw rod; the two ends of each lead screw rod are connected with the inner ring support and theouter ring support in a rotary manner correspondingly; and the rotating motion of each lead screw rod is converted into the synchronous axial motion, along the corresponding lead screw rod, of the lead screw nut. The multiple nozzles are arranged on the multiple lead screw nuts correspondingly. The adjustable spray head can adapt to forging molds of different specifications and is suitable for being applied to an aluminum alloy hub forging automated production line so that the production cost can be lowered, the production switch time can be shortened and work efficiency can be improved; andthe adjustable spray head is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of nozzles, in particular to an adjustable nozzle. Background technique [0002] As one of the most important moving parts of a car, the wheel hub has high requirements on its performance, weight and service life. In recent years, aluminum alloy wheels stand out in the automotive industry due to their advantages of light weight, fast heat dissipation, good shock absorption performance, long life and good balance, and are widely used in various new models. Forging is the most advanced method for manufacturing aluminum alloy wheels. Aluminum alloy wheel forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. When the aluminum alloy wheel is forged, the cooling and lubrication of the mold is not only related to the quality of the final product, but also related to t...

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome that a lubricating nozzle in the prior art cannot adapt to forging dies of different specifications, and can only be realized by switching lubricating nozzles of different specifications, so that the production cost is increased, the time for changing production, and the work efficiency are increased. Low technical defects, thus providing a lubricating nozzle that can adapt to forging dies of different specifications, suitable for use in aluminum alloy wheel hub forging automatic production lines, in order to reduce production costs, reduce production change time, improve work efficiency, and has a simple structure and easy operation adjustable nozzle
