Abstract

A hydraulic press with micromotion of lower hammer is composed of energy-accumulating working cylinder, upper hammer connected to lowr end of piston rod for said working cylinder, U-shaped lower hammer for recepting said upper hammer in its U recess, and drive unit consisting of air cushion at both sides of lower hammer, communicated cylinders under lower hammer, and valves. Its advantages are convenient connection and high beat speed and precision.

Description

1. Technical field: [0001] The invention relates to a micro-movement hydraulic hammer with a lower hammer head, which belongs to a die forging hydraulic hammer. 2. Background technology: [0002] Among the existing die forging equipment in our country, the steam-empty die forging hammer is one of the main equipment. Compared with other die forging equipment such as mechanical presses and friction presses, the steam-empty die forging hammer has a simple structure, low price, fast striking speed, many strokes, good forming technology, and does not require billet making equipment, so it is widely used , especially suitable for small and medium batch production plants. [0003] However, with the development of production, the problems exposed by the steam-air hammer have become more and more prominent. These problems are mainly manifested in: ① high energy consumption, extremely low thermal efficiency, and its effective energy utilization rate is less than 2%; ② high vibration...
