Chip-free rotating and cutting machine

Abstract

The invention discloses a chip-free rotating and cutting machine, which comprises a frame, a cutting device and a clamping device, wherein the cutting device and the clamping device are both arrangedon the frame; the cutting device comprises a transmission sleeve, an adjusting sleeve, an installation panel and a plurality of cutting mechanisms; the adjusting sleeve can drive a plurality of cutting mechanisms to synchronously move along the diameter direction of the installation panel. The device is used for cutting pipe fittings. The cutting device uses a taper extrusion mode to achieve synchronous feeding, and the synchronous feeding of the plurality of cutting mechanisms can be controlled through the driving of the adjusting sleeve, so that the stress of the cutting mechanisms is uniform, the service life of the cutting mechanisms is prolonged, and the cutting mechanisms are not easy to damage; the clamping device uses a taper extrusion mode to achieve clamping, the concentricity ofthe pipe fitting can be ensured in the cutting process, and the cutting surface is flat and does not incline.

Description

technical field [0001] The invention relates to the field of hardware processing equipment, in particular to a chipless rotary cutting machine. Background technique [0002] In the past, metal pipes were cut with grinding wheels or circular saws. However, due to the high hardness of metal pipes, the grinding wheels or circular saws are easy to wear and have to be replaced frequently. A lot of sparks and debris will be generated during cutting, which is not environmentally friendly. In addition, the cut pipe has burrs and barbs, so it needs to be polished and polished twice to increase labor. [0003] At present, there is also a pipe cutting machine on the market that uses centrifugal force to feed the knife and cut it. Since the cutter is in the shape of a toothless disc, no chips are generated during the entire cutting process, so it is called chipless cutting. Chip cutting is not only lower in technical accuracy than chip-free cutting, but also prone to dust, especially ...

AI Technical Summary

Problems solved by technology

[0004] However, the feeding method of the existing chipless cutting machine is to use centrifugal force to feed the knife, the speed of the knife is difficult to control, the operation is quite difficult to adjust, and the incision is prone to deformation

Moreover, it is difficult to realize the synchronous feeding of multiple blades with this kind of feeding method, which makes the force of the blades uneven, and the blade is prone to chipping due to uneven force, which affects the life of the blades.
