Summary of the invention

The purpose of the utility model is to overcome the prior art shortcoming; The cutting tool of a kind of processing inclined end face (or " V " shape end face) rubber-plastic sealing ring is provided; A cutting tool can process the rubber ring product that Double End all has the various sizes of given bevel angle or " V " face; The product size precision that processes is very high, and surface quality is fine, meets the product technology requirement fully.

For realizing above purpose, the technical scheme of the utility model is: a kind of cutting tool of processing the inclined end face rubber-plastic sealing ring, cutter are fixedly on the knife bar; Knife bar is fixed on the tool rest, and tool rest is fixed on the cutter tower of lathe, it is characterized in that; The cutter front end is wedgelike, and point of a knife is provided with circular arc, and the cutter tail end is a column; Insert in the knife bar hole and fix, be provided with and at least onely be fixed on the knife bar 30 ° to 60 ° of the angles of cutter and rotation cutter is oblique through screw.

The both sides that smatterer's tool is symmetricly set in rotation can be set; Said cutter tail end is coarser than blade, is cylinder or multiaspect scapus.

Advantage of the utility model and beneficial effect: installing one, can to process two end faces to cutter be the rubber ring on inclined-plane all, and the cutting tool that has two cutters can process the rubber ring that two end faces all are " V " shape face.When a cutter is fixed on the cutter tower of equipment such as lathe or machining center through tool rest; Rubber and plastic spare raw material workpiece is as managing material or the bar main axis rotation with equipment such as lathe or machining centers; Cutter touches the external diameter of workpiece under the program that edits; Move to workpiece diameter or center of circle direction along the tool axis direction, cut the end face and final cut-out of an inclination, so can process two end faces all is the rubber ring on inclined-plane; Two cutters are installed are processed the rubber ring of end face for " V " shape; Add man-hour, rubber and plastic spare workpiece is like the pipe material main axis rotation with equipment such as lathe or machining centers, cutter from workpiece diameter the axis direction along self progressively a certain end face of turner lean on the inclined-plane of inner radius; After this inclined-plane completion of processing; Another cutter processes the inclined-plane that leans on outer radius of this end face from the axis direction motion of workpiece outer radius by self, and two inclined-planes are combined into one " v " end face.Right latter two cutter is two inclined-planes of processing work other end respectively; During the inclined-plane completion of processing of this end face, workpiece is cut off by final, need not clamping again again and cuts off workpiece down and continue to process; Therefore avoided the softer rubber ring of quality under the clamping cut-out, so there is not the phenomenon of machining deformation.Whole working angles is the cutting edge cutting that utilizes the cutter front end, and along with deepening of cutting depth, expansion is pushed to the opening of the rubber and plastic spare that cut in the non-blade port position of cutter, carries out cutwork to make things convenient for blade further to go deep into workpiece.The efficient of this cutting tool converted products is higher, and the product end surface dimensional accuracy is high, and surface quality is good, and surface roughness can be lower than RA1.6 μ m; Utilize a cutting tool just can process the rubber ring product of the various diameter in equipment tactical diameter scopes such as lathe or machining center of identical end face structure, so processing cost is also lower, the scope of application is very wide.
