Abstract
The invention discloses a method for machining roll shafts of full-automatic melting-free lead ingot granulators. The method includes steps of 1) discharging, 2) forging, 3) rough machining, 4) quenching and tempering, 5) finish machining, 6) heat treatment, 7) drilling, 8) electric pulse machining and 9) linear cutting. The method has the advantages that the roll shafts can be machined conveniently, equipment can run stably, the sizes of extruded lead granules are consistent, the production efficiency can be improved, and the method is applicable to the field of production for lead acid batteries.
Description
Technical field
The present invention relates to the processing of lead-acid battery production equipment, relate in particular to a kind of processing method of automatically exempting to melt lead pig comminutor roll shaft.
Background technology
Automatically exempting to melt lead pig comminutor is lead-acid battery production equipment, is mainly used in, on the automatic assembly line of lead-acid battery, supporting the use with lead-power machine, has replaced the molten lead machine in traditional lead material manufacture process, casting grain machine or pelleter.Automatically exempt to melt lead pig comminutor automaticity high, reduced workman's labour intensity, improved production efficiency, reduced power consumption, realized zero-emission, zero and polluted.Wherein the processing method of roll shaft is to product quality, and runnability, production efficiency have a great impact.
Summary of the invention
The object of this invention is to provide a kind of easy to processly, can improve the quality of products, the processing method of automatically exempting to melt lead pig comminutor roll shaft of runnability, production efficiency.
The present invention is achieved in that the processing method of automatically exempting to melt lead pig comminutor roll shaft, it is characterized in that: comprise the following steps:
1), blanking: choose round bar, meet the material of length from round bar cutting;
2) forge: round bar is heated to 900 ~ 1100 ℃ and uses shaping mould forging forming, final forging temperature is not less than 830 ℃;
3), roughing: press from both sides the cylindrical of middle section with three-jaw on horizontal lathe, cylindrical and the end face of car B end; Tune with three-jaw, press from both sides positive B end cylindrical car interlude cylindrical, the cylindrical of A end and end face and bore endoporus;
4), modifier treatment: hardness is HRc28 ~ 32;
5), fine finishining: the cylindrical boring endoporus that presss from both sides positive B end with three-jaw; The cylindrical of holding with Internal hole positioning mill A end, interlude, B on grinding machine;
6), heat treatment: high-frequency quenching HRC hardness is HRc50 ~ 54;
7), boring: work in-process bores each liftout hole in the heart;
8), electric pulse: process each cavity on electric pulse machine;
9), line cutting: cut anti-slip tank on cutting on line machine.
The present invention is easy to process, and the lead button that make stable equipment operation, squeezes out is in the same size, has improved production efficiency.
Accompanying drawing explanation
