Description
Technical Field
The utility model relates to a cutter, concretely relates to twolip crescent grooving cutter, the utility model belongs to the technical field of the cutting.
Background
When products with grooves on inner end surfaces and inner grooves are machined, special cutters are needed for cutting, due to the structural particularity of the products, the requirements on angles and shapes of the cutters are strict, and no cutter meeting the conditions can be used so far, so that the cutting effect is poor, the cutting speed is low, and the machining efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve not have special cutter to cut to the product of internal terminal surface trough of belt, interior slot and lead to that the cutting effect is not good and cutting speed is slow, machining efficiency low problem, and then provide a twolip crescent grooving sword.
The utility model discloses a solve the technical scheme that above-mentioned problem was taken and be:
the utility model discloses a cutter body and tool bit, the rear end of tool bit is fixed as an organic whole with the front end of cutter body, the rake face of tool bit is equipped with the crescent moon groove, and the upper surface and the lower surface of crescent moon groove all are equipped with main cutting edge.
Further, the tool bit is provided with a rear tool face.
Further, the tool bit is provided with a secondary flank face.
Further, the auxiliary rear knife face is an arc knife face.
Furthermore, the upper surface of the front end of the cutter head is provided with a rake face chip groove.
Further, an alloy cutter head is arranged on the upper portion of the front cutter face.
The utility model has the advantages that:
1. the utility model can cut the inner end surface groove or the inner groove, reduce cutting force, improve the rigidity of the cutter, and ensure the smooth processing of the deep groove;
2. the chip removal is smooth, and the surface quality of the product is improved;
3. when the utility model is used for cutting, the stress deformation of the workpiece can be effectively controlled;
4. the utility model can increase the cutting speed and improve the processing efficiency;
5. the service life of the cutter is prolonged, and smooth processing of the deep hole groove is guaranteed.

Detailed Description
The first embodiment is as follows: the embodiment is described with reference to fig. 1 to 3, and the double-edged crescent grooving tool according to the embodiment includes a tool body 1 and a tool bit 2, wherein a rear end of the tool bit 2 is fixed to a front end of the tool body 1, a rake surface of the tool bit 2 is provided with a crescent groove 2-1, and an upper surface and a lower surface of the crescent groove 2-1 are both provided with main cutting edges 2-2.
The crescent groove 2-1 is used for reducing cutting force, solving the problem of insufficient rigidity of the cutter and ensuring smooth processing.
The second embodiment is as follows: the present embodiment will be described with reference to fig. 1 to 3, and the cutting insert 2 of the present embodiment is provided with flank surfaces 2-3.
Other components and connections are the same as those in the first embodiment.
The third concrete implementation mode: the present embodiment will be described with reference to fig. 1 to 3, and the cutting insert 2 of the present embodiment is provided with minor flank surfaces 2 to 5.
Other components and connection relationships are the same as those in the first or second embodiment.
The fourth concrete implementation mode: the present embodiment will be described with reference to fig. 1 to 3, and the minor flank surface 2-5 of the present embodiment is an arc-shaped flank surface. The circular arc shape of the minor flank surface 2-5 is to enhance the rigidity of the tool.
Other components and connection relationships are the same as those in the first, second or third embodiment.
The fifth concrete implementation mode: the present embodiment will be described with reference to fig. 1 to 3, and the top surface of the tip of the tool bit 2 according to the present embodiment is provided with rake face flutes 2 to 4.
Other components and connections are the same as those of the first, second, third or fourth embodiments.
The sixth specific implementation mode: the present embodiment will be described with reference to fig. 1 to 3, and alloy tips 2 to 6 are provided on the top of the rake face in the present embodiment.
Other components and connection relationships are the same as those in the first, second, third, fourth or fifth embodiment.
The working principle is as follows:
the main cutting edge is responsible for cutting the work piece, and the supplementary main cutting edge of vice cutting edge assists the cutting of main cutting edge, and the chip breaker of rake face helps the smear metal to discharge, increases the sharpness of main cutting edge, is favorable to the cutting. During machining, transverse layered machining is adopted, cutting force is decomposed, cutter rigidity is improved, and the machining difficulty of the end face groove is limited.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed with the preferred embodiment, it is not limited to the present invention, and any skilled person in the art can make modifications or changes equivalent to the equivalent embodiment without departing from the technical scope of the present invention, but all the modifications, equivalent substitutions, and improvements made to the above embodiments within the spirit and principle of the present invention still belong to the protection scope of the technical solution of the present invention.
