Phosphor copper ball cold header

Abstract

The invention discloses a phosphor copper ball cold header, and belongs to the field of phosphor copper machining. The phosphor copper ball cold header comprises a base; a conveying mechanism, a guiding mechanism and a rolling mechanism are sequentially arranged at the top of the base from right to left; the conveying mechanism comprises an N-shaped plate and a first driving motor, two conveying rollers are rotationally connected in the N-shaped plate, one end of one conveying roller is fixedly connected with a first driven belt wheel, and the output end of the first driving motor is fixedly connected with a first driving belt wheel; the material guiding mechanism comprises a barrel body and a sliding plate, three pairs of straightening rollers are rotatably connected into the barrel body,two sliding grooves are formed in the top of the base, the two sliding grooves are slidably connected with the sliding plate, and the front side of the top of the sliding plate is fixedly connected with a second driving motor; and the rolling mechanism comprises a rolling box and a water storage tank, two rolling rollers are rotatably connected in the rolling box, two third driving motors are fixedly connected to the left end of the rolling box, and the third driving motors are fixedly connected with the rolling rollers. The cold header is high in machining precision and high in stability, and a phosphor copper bar does not need to be preheated in advance.

Description

technical field [0001] The invention belongs to the field of phosphor bronze processing, in particular to a phosphor bronze ball cold heading machine. Background technique [0002] Phosphor copper is composed of bronze with added degassing agent, phosphorus content 0.03-0.35%, tin content 5-8%, and other trace elements such as iron, zinc, etc. It has good ductility and fatigue resistance. It can be used for electrical and mechanical materials, and its reliability is higher than For general copper alloy products, phosphor bronze is widely used as an intermediate alloy in copper casting, solder and other fields, and plays an important role in the development of the national economy. The forming of phosphor bronze balls requires processing of phosphor bronze rods. [0003] The existing processing methods of phosphor bronze balls are mainly through manual grinding and preheating processing. Manual grinding precision is low and labor intensity is high. Preheating processing needs...

Problems solved by technology

[0003] The existing processing methods of phosphor bronze balls are mainly through manual grinding and preheating processing. Manual grinding precision is low and labor intensity is high. Preheating processing needs to heat the phosphor bronze to above 800 degrees before processing. This method not only consumes high energy , which greatly increases the production cost
