Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile precision assembly forging and pressing technology, and particularly relates to a precision assembly hot forming forging and pressing device for automobile tooling. BACKGROUND

[0002] Hot forming and forging and pressing are core processes for realizing precision forming of high-strength and lightweight automobile parts. The technology based on hot forming (also known as hot stamping or hot plate hardening) has been widely applied to the manufacturing of lightweight automobile parts. It can perform plastic forming on high-strength steel plates in a high-temperature state and obtain excellent mechanical properties. The hot forging and pressing of precision components for automobile tooling is usually performed by a hot forging machine.

[0003] The existing hot forging and pressing machine (publication number: CN118417479A) has at least the following disadvantages: the device sets a retractable coaming on the pressing die. When the pressing die moves down for hot forging and pressing, the coaming can protect the forging and pressing part to prevent sparks from splashing. However, since the coaming cannot move autonomously on the pressing die, the pressing die needs to be raised by a large distance after hot forging and pressing of the workpiece to ensure that there is enough gap space between the bottom end of the coaming and the die seat for personnel to operate the forged workpiece. For example, without the coaming, the pressing die only needs to be raised by 20 cm to leave sufficient operating space. With the coaming, the pressing die needs to be moved by the height of the coaming in addition to the 20 cm to leave sufficient operating space. This increases the lifting distance of the pressing die during forging and pressing, which not only reduces the hot forging and pressing efficiency of the workpiece but also increases the energy consumption of the hydraulic system of the hot forging machine. Therefore, the present utility model is proposed. UTILITY MODEL CONTENTS

[0004] The utility model aims to solve the shortcomings in the prior art and provides a precision component hot forming forging and pressing device for automobile tooling.
