Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be embodied in many other forms different from the embodiments described herein and similar modifications may be made by those skilled in the art without departing from the spirit and scope of the invention, and it is therefore not to be limited to the specific embodiments disclosed below.

The utility model provides a be provided with general cutter body of milling of old and useless turning tool piece is provided with general handle of a knife main part 1, it has old and useless blade 5 to inlay on the general handle of a knife main part 1, through adjusting general handle of a knife main part 1 and old and useless blade 5 mill the parameter, when guaranteeing processingquality, reduce cost consumes.

As shown in fig. 1 and fig. 2, the universal milling cutter body provided with the waste turning blades provided by the utility model comprises a universal cutter handle main body 1, a square shoulder milling cutter head 3 is arranged on the universal cutter handle main body 1, a cutter containing groove 2 is made at the front end of the square shoulder milling cutter head 3 according to the clamping requirements of blades, and a waste blade 5 is fixedly arranged in the cutter containing groove 2 through a screw 4; the rear end of the general knife handle main body 1 is connected with the general knife body clamp and the general knife handle, and therefore the general knife body clamp and the general knife handle are connected to a machine tool spindle to complete part processing.

When the square shoulder milling cutter head 3 works normally, the force applied is radial force, so the universal cutter handle main body 1 is required to have higher yield strength, otherwise, the universal cutter handle main body 1 is easy to form cutter back-off when working normally. The hardness of the screw 4 of the pressing blade is HRC38-40, the hardness difference between the screw 4 and the universal knife handle main body 1 cannot be too large, and otherwise, the thread of the knife body is easily damaged. Therefore, the material of the universal knife handle main body 1 is 42CrMo which is commonly used by a numerical control tool and belongs to ultrahigh strength steel, after heat treatment, the hardness is controlled to be HRC40-43, and the universal knife handle main body has higher yield strength; the general handle of a knife main part 1 preparation combines the anterior angle and the relief angle of old and useless blade 5 to design: the front angle and the back angle are 12 degrees, the inclination angle of the blade is 5 degrees, the protective arc of the cutting edge of the waste blade 5 is R0.08 degrees, the thickness from the cutting edge of the waste blade 5 to the bottom surface of the waste blade 5 is 4.78 +/-0.02 mm, so that the depth of the tool accommodating groove 2 manufactured by the universal tool handle main body 1 is 4.73mm below the diameter, the purpose is to enable the cutting edge to be 0.05 +/-0.02 mm higher than the top end of the tool groove, the waste blade 5 is not easy to generate the abrasion of a front tool face when cutting a workpiece, and the surface quality of the processed workpiece is improved; when the universal knife handle main body 1 is manufactured, the 35-degree sharp corner part is considered in the universal knife handle main body 1, the knife containing groove 2 of the universal knife handle main body 1 is slightly smaller than 35 degrees, the back angle of the waste blade 5 is 5 degrees, two surfaces for fixing the waste blade 5 in the knife containing groove 2 are made into corresponding 5 degrees, and therefore the waste blade 5 is in full contact with the contact surface in the knife containing groove 2 as far as possible.

The general knife handle main body 1 requires that the radial back-biting amount generally does not exceed 30% of the diameter of the knife body of the general knife handle main body, and the diameter of the general knife handle main body 1 is enlarged as much as possible on the premise of permission of a processing environment so as to ensure the production efficiency and the processing stability. Meanwhile, considering that the gap of the clamp used at present is 38mm-40mm, in order to ensure that the universal knife handle main body 1 does not interfere with the clamp, the universal knife handle main body 1 with the standard diameter of phi 32 is selected. In order to improve the processing efficiency and the service life of the cutter, the number of teeth is made into the three teeth with the maximum diameter range, and in order to avoid the resonance of the cutter, the tooth spacing angles are made into unequal arrangement of 110 degrees, 120 degrees and 130 degrees, thereby ensuring the processing quality. The machining is finished by using a VDL-600E vertical machining center, batch machining of 12 workpieces at a time is realized by matching with a special workpiece clamp, a forward milling mode is adopted, rough milling is carried out firstly, then finish milling is carried out, rough and finish machining separation is carried out on different axial positions of a cutter, full cutting edge utilization is realized by using layers layer by layer, and continuous machining of products is finished.

Learn according to the statistical result of in service behavior, use the utility model provides a be provided with general cutter body of milling of old and useless turning insert can the great degree save purchasing cost, the use cost of cutter is owing to adopt old and useless blade 5, consequently falls to 0.38 yuan/piece from 1.85 yuan/piece, and the cost accounts for and falls to 2% by 8%, is superior to the industry average level, and per 10000 work pieces of processing can save cost 14341.11 yuan.

In the aspect of machining efficiency, owing to adopt the utility model provides a be provided with general cutter body of milling of old and useless turning insert, the single reduces 180s when processing 12 uses in batches, reduces 15s when the stick is average to be processed, saves 180s when the single tool changing, and comprehensive machining efficiency improves.

The utility model provides a be provided with the general cutter body of milling of old and useless turning tool piece can promote and be used for machining center equipment to process about the thin wall outline.

The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be covered by the scope of the present invention.
