Description

Technical Field

[0001] The utility model relates to the field of roll forging machines, in particular to a roll forging machine with adjustable forging roll inclination angle for manufacturing tie rods. Background Art

[0002] Roll forging machines are mainly used for pre-forging of forgings and can also be used for final forging. The essence of roll forging deformation is the rolling extension of the billet. The cross-section of the billet becomes smaller and the amplitude of the surface increases. When the cross-section deformation is large, it needs to be completed through multiple rolling. The process design is mainly to reasonably determine the amount of reduction, widening and extension deformation of each step of roll forging. They depend on the size of the roller diameter, the shape and size of the hole, the temperature of the blank, and the deformation conditions such as cooling and lubrication. One end of the billet is clamped with a clamp and deformed (initial forming) and exited under the rolling of the first hole of the fan-shaped die. Then it is fed into the dieless space of the next hole, deformed again by rolling (pre-forming) and exit. According to the needs of deformation, it is gradually formed through multiple rolling to obtain the required formed workpiece (final forming). Roll forging machines are also required for processing in the manufacturing process of tie rods.

[0003] According to the patent CN215033259U, a roll forging machine with adjustable forging roller inclination includes a base, a right-angle frame is provided on the top of the base, a driving mechanism is provided on the left side of the right-angle frame and extends to the inside thereof, a forging roller assembly is provided on the right side of the driving mechanism, and the top of the base and the bottom of the inner wall of the right-angle frame are both provided with an adjustment mechanism movably connected to the forging roller assembly, and the driving mechanism includes a motor, which is fixedly mounted on the top of the right-angle frame. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved: by setting an adjustment mechanism, the motor can be turned on and off. The dynamic servo motor drives the cam to rotate, causing the balance plate to tilt under the support of the spring and the second support rod, driving the two pull rods on the left to move opposite to each other, and driving the right side of the U-shaped frame to shift. Under the support of the first support rod and the support shaft, the U-shaped frame is more stable, thereby adjusting the inclination angle of the two forging rollers, and achieving the purpose of adjustable forging roller inclination. During use, the traditional method is simply to adjust the angle of the forging roller, and cannot accurately control the adjustment of the forging roller inclination, thereby affecting the quality of the pull rod manufacturing, causing great inconvenience in actual use, and causing serious waste of resources. For this reason, it is necessary to design a new technical solution to solve this problem. Utility Model Content
