Continuous extrusion method and equipment for lead brass

Abstract

The invention relates to a continuous extrusion method and continuous extrusion equipment for lead brass. The continuous extrusion method for the lead brass comprises the following steps of: discharging the rod material of the lead brass from a material discharging disk, straightening by using a straightening and feeding device, feeding into a heating furnace for heating so as to soften the rod material, feeding the rod material into the extrusion wheel groove of a continuous extrusion main machine, entering a cavity, extruding a product by using a mould, passing through an anti-oxidization protective pipe, entering a cooling and oxidization preventing device for cooling, and drying by using a blowing device to obtain a finished product. The equipment used in the method comprises the material discharging disk, the straightening and feeding device, the heating furnace, the continuous extrusion main machine, the cooling and oxidization preventing device, the blowing device and a main electric cabinet which are arranged in sequence. The processing temperature range of the lead brass, which is suitable for plastic processing, is provided by the extrusion method, processing fragility is avoided, and plasticity is improved. In the equipment used in the method, the feeding speed of the feeding device and the heating frequency of the heating furnace can be automatically controlled to be synchronized with the operating speed of the continuous extrusion main machine, so that the rod material is prevented from being broken in the extruding process.

Description

technical field [0001] The present invention relates to extrusion methods, especially continuous extrusion methods, and also to continuous extrusion equipment. Background technique [0002] The traditional production method of lead brass wire is: horizontal continuous casting-multi-mode drawing method. The main production process is as follows: horizontal continuous casting→slitting→heating→rolling→pickling→stretching→bright annealing→finishing stretching→inspection, packaging, storage. This process has many disadvantages, such as: many production processes, long production cycle, high cost, and the size of raw materials needs to be selected according to the finished product specifications. It is generally large, multi-variety, and multi-standard, which brings many difficulties to mass production. ; At the same time, two-phase brass is easy to work harden, and with the increase of the second phase, the plasticity drops sharply. [0003] Due to the high strength and hardnes...
