Abstract
The invention discloses a cutter for processing O-shaped grooves of rubber and plastic sealing rings. The cutter comprises a cutter holder, a cutter bar and a cutter blade arranged on the cutter bar, the right end of the cutter bar is fixedly connected with the cutter holder, the left end of the cutter bar is provided with a bayonet, the right end of the bayonet is an oblong limit section, the middle of the bayonet is a tapered extension section, the left end of the bayonet is used for fixing a threaded port of the cutter blade, the cutter blade comprises a blade body, connecting rods and O-shaped groove cutting edges, the connecting rods and the O-shaped groove cutting edges are symmetrically arranged on two sides of the blade body, the O-shaped groove cutting edges are arranged at outer ends of the connecting rods and are arc-shaped, a threaded hole matched with the threaded port of the cutter bar is arranged at the center of the blade body, and the diameter of the O-shaped groove cutting edges corresponds to the width of the oblong limit section at the right end of the bayonet. The cutter for processing the O-shaped grooves of the rubber and plastic sealing rings is high in processing precision and processing efficiency and smooth and flat in processed surface.
Description
Technical field
The present invention relates to the machining tool field, particularly relate to a kind of cutter for the processing O-shaped groove of rubber-plastic seal ring.
Background technology
In the prior art, the method for producing rubber-plastic sealing ring generally is to finish by thermoplastic processes, and is first that the raw material such as polypropylene or rubber are molten for liquid, then, sets certain temperature and pressure again and carry out repeatedly hot pressing in mould, is shaped to sealing ring.The defective of this technique is before production, needs to hold mould successfully according to the shape of sealing ring first.Because the cost of mold is higher, and the cycle is long, and the product size that traditional mold pressing is produced is unstable, and sealing ring material is selected also dumb, so obviously be uneconomic for the rubber-plastic sealing ring production of multi-varieties and small-batch.Therefore, the technique of producing rubber-plastic sealing ring without mould has been arranged.This process is to produce first the sealing tubbing of polyester material or elastomeric material with thermoplastic processes, then adopt cutter that the sealing tubbing is carried out machining according to requirements such as the material of sealing ring product, shape, sizes at Digit Control Machine Tool, produce needed sealing ring.Therefore, need to adopt different cutting tools to finish for difform sealing ring.Still do not have in the prior art thisly to process needed cutter without the mould sealing ring, particularly process the cutter of O shape groove.
Summary of the invention
Purpose of the present invention is providing a kind of cutter for the processing O-shaped groove of rubber-plastic seal ring.
The technical scheme that can realize goal of the invention of the present invention is as follows:
A kind of cutter for the processing O-shaped groove of rubber-plastic seal ring, it comprises tool rest, knife bar and be arranged at bite on the knife bar, described knife bar right-hand member is fixedly connected with tool rest, the knife bar left end is provided with bayonet socket, the bayonet socket right-hand member is oblong spacing section, the middle part is the taper extension, left end is for being used for the fixedly screw thread mouth of bite, described bite comprises cutter hub, symmetry is horizontally placed on connecting rod and the O shape groove cutting sword of the taper of cutter hub both sides, O shape groove cutting sword is arranged at the connecting rod outboard end, the cutter hub center is provided with the screwed hole that cooperates with the screw thread mouth of knife bar, described O shape groove cutting sword be shaped as circular arc, the oblong spacing section width of the diameter of O shape groove cutting sword and described bayonet socket right-hand member is corresponding.
Beneficial effect of the present invention is provided with bayonet socket for the knife bar left end because of a kind of cutter for processing O-shaped groove of rubber-plastic seal ring of the present invention, during the assembling bite, one end O shape groove cutting sword of bite is imported in the bayonet socket of knife bar, contact with the right flank of spacing section of oblong, then by bolt, the screwed hole of cutter hub center setting and the cooperation of the screw thread mouth on the bayonet socket O shape groove cutting sword is fixed on the knife bar.Because the O shape groove cutting sword of bite both sides is symmetrical arranged, therefore, spacing section of the bayonet socket by knife bar spacing, can guarantee the level of the O shape groove cutting sword of bite, the O shape groove precision of the sealing ring of processing is improved, and improve the efficient of processing, make machined surface smooth smooth.
Description of drawings
Fig. 1 is schematic diagram of the present invention.
Among the figure, 1 is tool rest, and 2 is knife bar, and 3 is bayonet socket, and 4 is spacing section, and 5 are the taper extension, and 6 is screw thread mouth, and 7 is cutter hub, and 8 is connecting rod, and 9 is O shape groove cutting sword, and 10 is screwed hole.
The specific embodiment
With reference to a kind of cutter for the processing O-shaped groove of rubber-plastic seal ring shown in Figure 1, it comprises tool rest 1, knife bar 2 and be arranged at bite on the knife bar 2, described knife bar 2 right-hand members are fixedly connected with tool rest 1, knife bar 2 left ends are provided with bayonet socket 3, bayonet socket 3 right-hand members are oblong spacing section 4, the middle part is taper extension 5, left end is for being used for the fixedly screw thread mouth 6 of bite, described bite comprises cutter hub 7, symmetry is horizontally placed on connecting rod 8 and the O shape groove cutting sword 9 of the taper of cutter hub 7 both sides, O shape groove cutting sword 9 is arranged at connecting rod 8 outboard end, cutter hub 7 centers are provided with the screwed hole 10 that cooperates with the screw thread mouth 6 of knife bar, described O shape groove cutting sword 9 be shaped as circular arc, oblong spacing section 4 width of the diameter of O shape groove cutting sword 9 and described bayonet socket 3 right-hand members is corresponding.Because knife bar 2 left ends are provided with bayonet socket 3, during the assembling bite, one end O shape groove cutting sword 9 of bite is imported in the bayonet socket 3 of knife bar 2, contact with the right flank of spacing section 4 of oblong, the screwed hole 10 that then arranges by bolt, cutter hub 7 centers and the cooperation of the screw thread mouth 6 on the bayonet socket 3 are fixed in O shape groove cutting sword 9 on the linking arm 2.Because the O shape groove cutting sword 9 of bite both sides is symmetrical arranged, therefore, spacing section 4 of the bayonet socket 3 by knife bar 2 spacing can guarantee the O shape groove precision of the sealing ring of processing to be improved the level of the O shape groove cutting sword 9 of bite, and improve the efficient of processing.
