Embodiment 1

[0038] The structure of the spinning machine in this embodiment, the top view of the wheel flexible spinning equipment is as follows figure 1 As shown, the main components are: bed 1, outer rotation wheel assembly A2, inner rotation wheel assembly A3, spindle motor 4, gear box 5, main shaft 6, process axis 7, workpiece 8, outer rotation wheel assembly B9, inner rotation Wheel assembly B10, tail top 11 and inner rotation wheel 33;

[0039] The main shaft motor 4 of the equipment is connected with the gear box 5 through a coupling, and the interior of the gear box 5 is transferred to the main shaft 6 through gears to make the main shaft rotate. The main shaft 6 can be installed to extend the process shaft 7, and the spinning workpiece 8 is installed on the process shaft 7 and then connected to the main shaft 6. The main shaft and the process shaft are processed with a tapered surface for quick installation and disassembly. The outer rotary wheel assembly A2 and the outer rotary...

Embodiment 2

[0042] In this embodiment, the horizontal double pair of wheel multifunctional and variable-size composite flexible spinning equipment can be formed by one-time spinning, and the wheel seat of the wheel assembly is equipped with a normal wheel 24, an angle wheel 25, and a flanged fixed wheel 28 and cutter 32, such as Figure 8 As shown, the angled rotary wheel is used in the first pass of the initial spinning. Due to the limited space between the workpiece and the spindle, the normal rotary wheel 24 cannot be close to the root. Therefore, the normal spinning process is used first. Initial angle, then select the angle wheel 25, and use the angle wheel 25 to spin to the root, such as Figure 10 shown;

[0043] Then use the normal spinning wheel 24 to carry out the wheel spinning after the spinning space is opened, and use the normal spinning wheel 24 and the internal turning wheel 33 to form the wheel spinning, as figure 1 As shown, due to the small rounded corners at the inne...

Embodiment 3

[0047] In this embodiment, the horizontal double paired wheel multi-functional and variable-size composite flexible spinning equipment can expand the processing capacity. The inner wheel assembly platform of the opposite wheel flexible spinning equipment is a detachable structure, and the inner wheel assembly platform is arranged below. The lead screw guide rail, after being removed, the stroke of the equipment is enlarged, and the form of a single pair of wheels and a mandrel 27 is adopted, which can spin multi-angle, special-shaped, and large-sized workpieces 26 to realize a multifunctional machine, such as Figure 9 shown.

[0048] Therefore, the equipment has spinning, trimming, edge trimming, and can also have a multifunctional machine for mold spinning.

Abstract

The invention provides horizontal type double-pair-wheel multifunctional variable-size composite flexible spinning equipment, and belongs to the technical field of flexible spinning equipment. According to the horizontal type double-pair-wheel multifunctional variable-size composite flexible spinning equipment provided by the invention, an outer spinning roller assembly A and an outer spinning roller assembly B are installed on a Y-axis platform, an X-axis platform is arranged below the Y-axis platform, an inner spinning roller assembly A and an inner spinning roller assembly B are installed on a V-axis platform, a U-axis platform is arranged below the V-axis platform, and the X-axis platform and the Y-axis platform are controlled to move in cooperation with the V-axis platform and the U-axis platform through a servo motor and a screw rod; and normal spinning rollers, angle spinning rollers, flanging fixed rollers and cutters are arranged on the two sides of a spinning roller base. According to the horizontal type double-pair-wheel multifunctional variable-size composite flexible spinning equipment provided by the invention, a spindle rotates to drive a spinning workpiece to rotate, and the angles of inner spinning rollers and outer spinning rollers are adjusted through rotating devices at the bottoms of the assemblies, so that the spinning rollers are perpendicular to the surface of the workpiece in the spinning process; the two-axis motion platforms are arranged below the inner spinning roller sets and the outer spinning roller sets and controlled by the servo motor, so that multi-shape machining of a workpiece can be achieved; and two pairs of inner spinning roller sets and two pairs of outer spinning roller sets are arranged to form a double-pair-wheel mode, so thatstress on machining large-size workpieces is balanced, and the spinning effect is good.

Description

technical field [0001] The invention relates to a horizontal double-wheel multi-functional and variable-size composite flexible spinning equipment, which belongs to the technical field of flexible spinning equipment. Background technique [0002] As an important branch of plastic processing, the spinning process has the advantages of good flexibility and low cost. It is suitable for processing a variety of metal materials. It is an economical and rapid method for forming thin-walled rotating parts. The field of metal rice processing technology occupies an important position, and it has also been widely used in the fields of chemical industry, machinery manufacturing, electronics and light industry. [0003] The spinning forming process has unique advantages in the forming of thin-walled bottom cover structures compared with welding and deep drawing due to its advantages of simple mold, flexible process, and wide adaptability. It is currently widely used in conical covers, sp...
