MUP
It achieves high-precision upset forging without parting line (burr) by preventing the grip die from opening at heading process.
Our upsetter has a hydraulic cylinder and a servo-driven grip mechanism, which solves the problems of existing machines. Achieves high precision upset forging without burrs.
Feature
Strong eccentric load properties
In the upset method allowing multi process forging, great eccentric load is applied to the heading slide of the machine by change of load, depending on processes. Model MUP, featuring remarkable durability, enables absorption of all eccentric load, thanks to the double crank shafts, serving as a driving source of the heading slide, provided on the both sides of the body.
Powerful grip mechanism
Even though the heading slide has enough resistance to eccentric load, the upsetter cannot work successfully if its grip mechanism does not have enough resistance to eccentric load. Model MUP incorporates a unique mechanism, a lever pivoted by a strong king pin, fully withstanding a large eccentric reaction force generated in the grip die.
Simple and rational mechanism
Model MUP features a simple and unique mechanism without any joint system, a bottleneck of conventional upsetters, in which links are connected with pins. It allows MUP to enjoy a good reputation as a superior model, virtually free from maintenance cost, with less noise and vibration, as well as excellent durability to wear.
