Abstract
The utility model discloses a square broach. A handle part (1), a neck part (2), a transition tapered part (3), a front guide part (4), a cutting part (5) and a rear guide part (6) are arranged on the square broach from front to back in sequence, wherein the cutting part comprises cutting teeth (51) and finishing teeth (52) from front to back in sequence; the cross section of each of the front guide part (4), the cutting part (5) and the rear guide part (6) is rectangular or square; the cutting teeth have an alternate cutting type structure; the finishing teeth have a layered structure; the rise per tooth of the cutting teeth is 0.09-0.13 mm; the rise per tooth of the finishing teeth is 0.006-0.010 mm; and tooth pitches of chip pockets of both the cutting teeth and the finishing teeth are lengthened. By the square broach, rough machining and finish machining of a square hole can be finished at a time, so that the production efficiency is extremely high, the accuracy of the milled square hole is high, and the cost can be effectively reduced.
Description
Technical field
The utility model relates to a kind of broaching tool, especially a kind of square broach be used to processing cubic hole.
Background technology
Original cubic hole forming method is boring-bore hole-fraising-grinding out, complex procedures and unstable product quality.
So, need a kind of new cubic hole processing device to address the above problem.
The utility model content
Goal of the invention: the purpose of this utility model is for cubic hole manufacturing procedure complexity in the prior art and the unsettled deficiency of quality, and a kind of precision height, efficient square broach high and with low cost are provided.
Technical scheme: for achieving the above object, square broach of the present utility model can adopt following technical scheme:
A kind of square broach, described square broach sets gradually pelmatozoa from front to back, neck, the transition tapering, front pilot, cutting portion and rear pilot, described cutting portion is followed successively by cutting teeth and finishing teeth from front to back, described front pilot, the cross section of described cutting portion and described rear pilot is rectangle or square, described cutting teeth is wheel cut structure, described finishing teeth is hierachical structure, the rise per tooth of described cutting teeth is 0.09-0.13mm, the rise per tooth of described finishing teeth section is 0.006-0.010mm, and cutting teeth chip pocket and finishing teeth chip pocket are the tooth pitch type that lengthens.
Beneficial effect: compare with background technology, process cubic hole with square broach of the present utility model and can disposablely finish the processing of thick, smart hole, have very high production efficiency, the cubic hole precision of processing is higher, and can effectively reduce cost.
Description of drawings
Fig. 1 is the front view of the utility model square broach;
Fig. 2 be the utility model square broach A-A place cutaway view;
Fig. 3 be the utility model square broach B-B place cutaway view.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
See also Fig. 1, Fig. 2, shown in Figure 3, a kind of square broach of the present utility model, square broach sets gradually pelmatozoa 1, neck 2, transition tapering 3, front pilot 4, cutting portion 5 and rear pilot 6 from front to back, and cutting portion 5 is followed successively by cutting teeth 51 and finishing teeth 52 from front to back.The cross section of front pilot 4, cutting portion 5 and rear pilot 6 is rectangle or square, cutting teeth is wheel cut structure, finishing teeth is hierachical structure, the rise per tooth of cutting teeth is 0.09-0.13mm, the rise per tooth of finishing teeth section is 0.006-0.010mm, and cutting teeth chip pocket and finishing teeth chip pocket are the tooth pitch type that lengthens.Wherein shank 1, in order to clamping broaching tool and transferring power; Neck 2 plays connection function; Workpiece is introduced with broaching tool front pilot 4 in transition tapering 3; Front pilot 4 plays guiding function, prevents that broaching tool is crooked; Cutting portion 5 is finished cutting, smoothing and calibration operation; Rear pilot 6 is used for holding workpieces, prevents that cutter tooth from cutting off front finished surface and the cutter tooth of damaging because workpiece is sagging.Process cubic hole with square broach of the present utility model and can disposablely finish the processing of thick, smart hole, have very high production efficiency.Front pilot 4 and cutting portion 5 are provided with guiding gutter, and the import of guiding gutter is arranged between front guide part 2 and the transition tapering 3, and the outlet of guiding gutter is separately positioned on cutting teeth section 51 and the finishing teeth section 52 of cutting portion 5.Cutting portion 5 has four cutting faces, all has cutting edge on the cutting face, and wherein the cutting edge of each center line both sides, cutting face becomes " V " shape to arrange.The two ends of square broach are provided with centre bore, conveniently grip.
As mentioned above, square broach of the present utility model is compared with prior art processed cubic hole with cubic hole of the present utility model broaching tool and can disposablely be finished the processing of thick, smart hole, has very high production efficiency, the cubic hole precision of processing is higher, and can effectively reduce cost.
