Spraying processing equipment for processing punching sheet of cold-formed section steel

Abstract

The invention discloses spraying processing equipment for processing a punching sheet of cold-formed section steel. The equipment comprises a material sheet groove box, a material sheet arranging mechanism, an atomizing and spraying mechanism and an output conveying belt, wherein the material sheet arranging mechanism comprises a conveying frame plate, a material sheet arranging mechanism, an electromagnetic heating mechanism and a progressive ascending sheet arranging mechanism, and a plurality of sheet arranging delivery plates are distributed on the inner side of the conveying frame plate in parallel; the atomizing and spraying mechanism comprises a spraying box, an ultrasonic atomizing nozzle and a liquid conveying pipe, wherein one end of the liquid conveying pipe is fixedly connected with a coating liquid pumping mechanism. According to the device, the progressive ascending sheet arranging mechanism is used for conveying, sheet arranging delivery plates are used for arranging punched material sheets one by one, the material sheets are conveyed into a spraying limiting hole in a rising mode and directly face an output nozzle of an atomizing and spraying mechanism, an ultrasonic oscillator drives a vibration resonance curved sheet to conduct ultrasonic oscillation to perform acoustic oscillation cavitation on the coating liquid, so that the coating liquid is vibrated and burst to form fine atomized particles to be sprayed to the surface of a punching sheet, and therefore, the surface of the material sheet is coated more uniformly, and the coating efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of coating, in particular to cold-formed steel punching and spraying processing equipment. Background technique [0002] Stainless steel stamping sheet is a forming processing method that applies external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation, thereby obtaining workpieces (stamping parts) of required shape and size, stamping and Forging belongs to plastic processing (or pressure processing), which is collectively called forging. The blanks of stamping sheets are mainly hot-rolled and cold-rolled steel plates and steel strips. The spray coating processing technology is developed on the basis of traditional processes. The new process of coating treatment can form an anti-oxidation and anti-rust protective coating on the surface of the stamping sheet. The protective effect is numbered. It forms a coating layer on the metal surface through a s...

Problems solved by technology

[0003] However, the existing surface coating equipment for stamping sheets can still only coat one side of the stamping sheets one by one, and manually arrange the sheets to place each stamping sheet on the surface of the transmission mechanism in sequence, and transport the stamping sheets to the interior of the coating spray cabin , using the atomizing nozzle to spray the coating solution on the surface of the punched sheet. "Heating method, according to this method, the spraying solution is not heated in the circulation box, but is heated in the process of being supplied to the workpiece, and the amount of heated spraying solution is only necessary for one spraying process of

However, when such in-line heating is employed, the control of the temperature of the spraying solution is generally difficult, and in addition, a rather large heating device such as a heater is required to heat the spraying solution, which results in an increase in size of the device.

When a small heating device such as a heater is used to reduce the size of the device, a large temperature difference between the surface of the heating source and the spraying solution is made, which will result in the formation of products on the surface of the heating source, and at the same time Excessive heating of the spraying solution near the heating source will lead to the decomposition of the spraying solution, resulting in a decrease in the spraying effect of the product, and there are certain defects
