Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] In this example, four hammerheads 3 are used, and the four hammerheads 3 are arrayed at equal intervals along the axis of the workpiece in space.

[0029] A method for radially forging a lead screw, comprising the steps of:

[0030] Step 1, clamping the workpiece 2, one end of the workpiece 2 is clamped by the first manipulator 1;

[0031] Step 2, workpiece 2 is fed axially, refer to figure 1 , the first manipulator 1 clamps the workpiece 2 and feeds it in the direction of the radial forging hammer head 3, refer to figure 2 , the hammerhead 3 has a thread shape section a, and the end of the forming screw section on the workpiece 2 close to the hammerhead 3 is aligned with the thread shape section a on the hammerhead 3 near the workpiece 2;

[0032] Step 3, the workpiece 2 is rotated and fed;

[0033] refer to image 3 , the rotation angle...

Abstract

Disclosed is a method for forming a lead screw through radial forging. The method comprises the steps that a workpiece is clamped firstly, the workpiece is fed axially, the workpiece rotates and is fed, hammer beating forging is performed to enable a threaded shape to be formed on the two third part to the third fourth part of a formed lead screw section on the workpiece; a second mechanical arm is used for clamping the other end of the workpiece, a first mechanical arm releases and retreats, the workpiece rotates continuously and is fed, hammer beating and lifting are performed continuously to enable a threaded shape to be formed on the unformed part of the lead screw section on the workpeice, the workpiece is clamped by the second mechanical arm to be fed axially quickly, and discharging is performed. By means of the method for forming the lead screw through radial forging, the material utilization rate is improved, the production period is shortened, the strength of the surface of the lead screw is enhanced, the forming precision is high, the surface quality is good and high-performance and large-diameter lead screws can be machined.

Description

technical field [0001] The invention belongs to the technical field of advanced material forming, and in particular relates to a method for radially forging a forming screw. Background technique [0002] Rolling functional parts are not only the basic functional parts of machine tools, but also widely used in aviation, aerospace, vehicles, medical equipment and other fields. They are important general basic components in the machinery industry, and screw is an important part of rolling functional parts. With the rapid development of aviation, aerospace, weapons industry and equipment manufacturing industry, there is an increasing need for high-thrust, high-speed, high-precision, low-noise, high-performance, long-life functional components. There is an urgent need for high-speed, heavy-duty, high-performance and large-diameter lead screws. [0003] At present, the production of lead screw mainly adopts equipment such as thread grinder, and the cutting processing method is th...
