The advantage of this cutting method is that the equipment structure is simple, but the disadvantage is that the cutting pressure is not easy to control. If the cutting pressure is too small, the profile will not be cut, or the profile will be bent and deformed at the cutting position, which will af

Abstract

The invention relates to a chip-free cutting apparatus used for a plastic section bar. The apparatus comprises a worktable, a support, a driving cylinder, a cutting knife and a knife rest. The driving cylinder is fixed on the support, and the cutting knife is fixed at the bottom of the knife rest. The knife rest can horizontally and slidably fixed on bottom end of the driving cylinder along a cutting edge direction of the cutting knife. A guide groove is arranged on the support, wherein the guide groove inclines or bends to one side of the cutting knife from top to bottom. A follower cooperated with the guide groove is fixed on one end of the knife rest. According to the invention, simple upper and lower cutting motion is converted into a cutting motion of cutting while sliding, such that cutting resistance is buffered and tipping of the cutting knife is prevented so as to prolong a service life of the cutting knife, and improve safety performance of the equipment.

Description

technical field [0001] The invention relates to a cutting device for processing plastic profiles, in particular to a chipless cutting device for plastic profiles. Background technique [0002] In the currently known chipless cutting devices for plastic profiles, the cutter is usually cut vertically up and down, that is, the driving device drives the cutter to cut the profile vertically downward. The advantage of this cutting method is that the equipment structure is simple, but the disadvantage is that the cutting pressure is not easy to control. If the cutting pressure is too small, the profile will not be cut, or the profile will be bent and deformed at the cutting position, which will affect the appearance quality of the profile; If the impact force of the knife is too large in an instant, the cutting knife is easy to chip, which brings great hidden dangers to production and maintenance, and the utilization rate of equipment is not high, and the production cost increases....
