Problems solved by technology

When the diameter of the workpiece is small, the volume of the crank linkage mechanism can be tolerated, but when the diameter of the workpiece is large, the volume of the crank linkage mechanism is also increased accordingly. In most cases, due to the excessive volume of the crank linkage mechanism , the volume of the entire thread rolling machine is also very large, and the manufacturing cost is too high. Therefore, in the past, bolts with larger diameters were generally rolled. However, because the rolling efficiency is much lower than that of thread rolling, large diameter bolts The processing cost has also increased significantly

Embodiment 1

[0023] This embodiment is a method of thread rolling, which is as follows: using the principle of leverage to increase the running distance of the linear reciprocating power movement, and driving the thread rolling plate to reciprocate the thread rolling movement.

[0024] The basic idea of ​​this embodiment is: the shorter moving distance of the linear power source is amplified to a longer moving distance through the lever, that is, the length of the resistance arm of the lever is greater than the length of the power arm of the lever.

[0025] The effect of this embodiment is: the slow linear power source, such as: after the movement of the hydraulic cylinder is amplified by the lever, it can form a thread rolling action with a long movement distance and fast movement. This form of thread rolling motion is very useful for thread rolling of large bolts.

[0026] The lever scaling mechanism may be a crank rocker mechanism, or a scaling mechanism formed by meshing large and smal...

Embodiment 2

[0029] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment regarding linear reciprocating power motion. The linear reciprocating power movement described in this embodiment is one of hydraulic, pneumatic or electric linear drive.

[0030] Linear reciprocating power motion can have many forms, the key is to provide power. In practice, there are not many ways to provide linear power, such as electricity, gas and hydraulic. These three linear reciprocating motions with power have their own characteristics. Generally speaking, hydraulic pressure is more suitable for the power of thread rolling.

Embodiment 3

[0032] This embodiment is a thread rolling machine, comprising: a fixed thread rolling board 1 and a sliding thread rolling board 2 installed on the bed, the sliding thread rolling board is connected with a motion zoom mechanism 3, and the motion zoom mechanism is connected with Linear reciprocating power mechanism 4 connections, such as figure 1 shown.

[0033] The fixed thread rubbing board and the sliding thread rubbing board that clamp the workpiece 5 and perform rubbing processing need to have linear motions parallel to each other to realize rubbing processing. In this embodiment, the linear driving force of the linear reciprocating power mechanism is amplified by a lever mechanism to produce a thread-rolling motion with fast movement and a relatively large movement distance.

[0034] The effect of using the motion scaling mechanism is to amplify the short-distance motion of the linear reciprocating power mechanism into a longer-distance motion while increasing the motio...

Abstract

The invention relates to a thread rolling method and a thread rolling machine. The thread rolling machine comprises a fixed thread rolling plate and a gliding thread rolling plate mounted on a bed body; the gliding thread rolling plate is connected with a movement zooming mechanism, and the movement zooming mechanism is connected with a liner reciprocating power mechanism. By lever principle, the zooming of a movement distance is formed; meanwhile, zooming of movement speed is generated, slow action of hydraulic movement is changed so as to adapt to the rapid movement of thread rolling. The method can be well applied to the thread rolling of a large bolt, thereby changing the situation of applying a very big crank rocker mechanism to the thread rolling of a big bolt, shortening an overall structure of the thread rolling machine, and reducing the cost.

Description

technical field [0001] The invention relates to a thread rolling method and a thread rolling machine, which are a method and mechanical equipment applied to mechanical processing, and are a method and a machine tool specially used for thread processing. Background technique [0002] The thread rolling machine uses two thread rolling plates to clamp the workpiece in the middle, and the two thread rolling plates move toward each other quickly to produce threads on the workpiece. Traditional thread rolling machines use a motor to drive the crank connecting rod mechanism to produce reciprocating motion. , to drive the thread rubbing board to reciprocate and rub the thread. This transmission method has been used for nearly a hundred years and has almost become the fixed pattern of thread rolling machines without any change. The transmission form of this crank-link mechanism has the advantages of good transmission rigidity and simple structure, but the volume is relatively large....
