Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of hot forging machines, in particular to an anti-impact device for a hot forging machine. BACKGROUND

[0002] A hot forging machine is a device that uses impact force or pressure to plastically deform heated metal blanks, thereby obtaining forged parts with specific geometric shapes and sizes. It is usually composed of a machine body, a working mechanism (such as a hammer head or a pressure head), a power system, and a control system. By heating the blank to reduce its deformation resistance, the blank is then subjected to extrusion, impact, or stretching, etc. processing using powerful force, and finally shaped into the desired forged part. Hot forging machines are widely used in the automotive, aerospace, and mechanical industries to manufacture various high-strength, high-performance metal parts.

[0003] A hot forging machine anti-impact device is disclosed in the utility model patent with publication number CN221695149U, which includes a fixed shell. The outer side of the fixed shell is slidably connected with a resistance shell at the upper end. The bottom wall of the fixed shell is fixedly connected with a conical seat through evenly distributed dampers. The upper side of the conical seat is provided with evenly distributed transmission rods. The upper side of the transmission rods is in contact with the top wall of the resistance shell. The side wall of the fixed shell is fixedly connected with inclined seats through evenly distributed dampers two. The inclined surfaces of the conical seat are in contact with the inclined surfaces of the adjacent inclined seats. This hot forging machine anti-impact device uses spring force and hydraulic damping to resist the horizontal and vertical flexible impact of the hot forging machine, effectively improving the service life of the device and making it easy to use.

[0004] However, in actual use, it was found that the resistance shell relies on dampers and springs to achieve buffering, thereby improving the anti-impact effect.

[0005] However, when the hammer head of the forging machine continuously moves up and down to knock and forge the workpiece on the resistance shell, the resistance shell is buffered under the action of the dampers and springs. However, the continuous knocking of the hammer head will cause the resistance shell to move downward again before it is fully reset, thereby causing the workpiece to exceed the range of the hammer head, affecting the forging precision and effect. Therefore, an anti-impact device for a hot forging machine is provided. UTILITY MODEL CONTENTS
