The plunge tooling technique of the present invention avoids slotting tool profile angle and workpiece in backhaul and violent friction occurs and damages, and profile manufacture is accurate, and the type hole inserted out reaches requirement, and this technique can be generalized to the plunge tooling technique in different shaped hole.
Description
Technical field
The invention belongs to field of machining, it is specifically related to the complete processing of a kind of slotting tool.
Background technology
Plunge tooling is the machining utilizing in the vertical direction opposite piece to do repeatedly translational motion processing groove and type hole. The mode of operation of slotting is similar with planing, but slotting tool clamping is on the knife bar of slotting machine ram bottom, it is possible to the Kong Zhongzuo stretching into workpiece erects to to-and-fro movement, is downwards working stroke, is upwards backhaul. The feeding movement of interval done by the workpiece being arranged on slotting machine worktable after each backhaul of slotting tool, difficulty of processing for slotting tool is bigger, but, in actual production, some the type holes often needed can only be processed by slotting machine, being applicable to single-piece or small size production processing, inner hole key slot or spline hole, also can process square hole and polygonal hole. For the inner hole key slot of not through hole or shoulder, slotting is almost unique method, and therefore, the complete processing of research slotting tool is very necessary and urgent.
The sword portion angle of slotting tool is made up of jointly anterior angle, relief angle and profile angle, form compound angle, if the sword portion anterior angle of slotting tool is greater than 3 ��, sword grinding process adopt angle plane before being perpendicular to process, the processing of profile angle can be caused defective, cause changing with the type hole of this plunge tooling.
Summary of the invention
It is an object of the invention to provide the complete processing of a kind of slotting tool, this technique solves slotting blade part anterior angle when being greater than 5 ��, and relief angle processes defective problem.
For achieving the above object, the technical solution used in the present invention is:
A complete processing for slotting tool, comprises sword grinder sequence, it is characterised in that: the complete processing of described sword grinder sequence is as follows:
1) set up the geometric model of slotting tool, according to slotting blade part anterior angle and profile angle, calculate slotting blade part compound angle;
2) according to slotting blade part compound angle grinding profile, 0.2mm surplus is stayed.
The complete processing of above-mentioned a kind of slotting tool, it is characterised in that: the method for calculation of described compound angle are: set anterior angle as ��, and relief angle is ��, and compound angle is ��, then ��=2arg [tg(��/2) �� tg ��/sin ��].
The complete processing of above-mentioned a kind of slotting tool, concrete technique is as follows:
1), expect: forging blanking;
2), plane: stay mill 0.4 ~ 0.5mm by figure plane four sides, keep parallel vertical;
3), milling: planar end surface is to total length;
4), clamp: draw head visible line and neck visible line by figure;
5), turning: look for positive car neck to size by figure and line, not headstock portion;
6), milling: by figure and line milling head profile, sword is wide stays 0.5 ~ 0.6mm, and before and after milling, angle keeps the cutter head amount of stretching out to add 1mm;
7), clamping: deburring, head profile repaiied by afterbody chamfering and file;
8), thermal treatment: tempering of quenching, sword HRC63 ~ 66, handle HRC33 ~ 48;
9), blow: blow sand;
10), flat mill: sharpening bar four sides is to size;
11), sword mill: according to slotting blade part compound angle grinding profile, stay 0.2mm surplus;
12), optics grinding machine: mill profile, to size, grinds relief angle.
The useful effect of the present invention: the plunge tooling technique of the present invention avoids slotting tool profile angle and workpiece in backhaul and violent friction occurs and damages, and profile manufacture is accurate, and the type hole inserted out reaches requirement, and this technique can be generalized to the plunge tooling technique in different shaped hole.
Accompanying drawing explanation
Fig. 1 is the front view of six side's slotting tools.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structural representation of the geometric model set up.
Embodiment
As depicted in figs. 1 and 2, the profile angle that design provides is 66 �� 22 ' (being 66.37 ��), the plane that this profile angle is perpendicular to center cutter line provides, but in reality is processed, due to the existence of anterior angle 5 ��, when grinding profile, the plane being perpendicular to 5 �� of anterior angles carries out ground finish, so profile angle 66 �� 22 ' (being 66.37 ��) will change, it is considered that if anterior angle is less than 3 �� of impacts of the grinding on profile not quite, it is possible to do not revise.
Six side's slotting tools as depicted in figs. 1 and 2, complete processing is as follows:
1), expect: forging blanking;
2), plane: stay mill 0.4 ~ 0.5mm by figure plane four sides, keep parallel vertical;
3), milling: planar end surface is to total length;
4), clamp: draw head visible line and neck visible line by figure;
5), turning: look for positive car neck to size by figure and line, not headstock portion;
6), milling: by figure and line milling head profile, sword is wide stays 0.5 ~ 0.6mm, and before and after milling, angle keeps the cutter head amount of stretching out to add 1mm;
7), clamping: deburring, head profile repaiied by afterbody chamfering and file;
8), thermal treatment: tempering of quenching, sword HRC63 ~ 66, handle HRC33 ~ 48;
9), blow: blow sand;
10), flat mill: sharpening bar four sides is to size;
11), sword mill grinding: according to slotting blade part compound angle grinding profile, stay 0.2mm surplus.
The technique of described sword grinder sequence is as follows:
Processing is set profile angle as ��, �� be compound angle, �� is anterior angle, two profiles are respectively plane A and plane B, if the friendship line of plane A and plane B, namely anterior angle line is MN, it is perpendicular to the plane C of MN, the friendship line gained angle of Calculation Plane C and plane A and plane B is ��, sets up geometric model, as shown in Figure 3, if AB=a, BD=1, OB=c, BE=b; Then:
A=1/tg(��/2)
Tg(��/2)=1/c, sin ��=c/b draws c=sin ��/[tg(��/2) tg ��]
Tg ��=a/b, draws b=1/ [tg(��/2) �� tg ��]
��=2arg [tg(��/2) �� tg ��/sin ��]
In the present embodiment, �� is 5 ��, and �� is 66.37 ��, is 66.53 �� through calculating compound angle ��, when grinding profile, it is necessary to carry out profile grinding by 66.53 ��.
12), optics grinding: mill profile, to size, grinds relief angle.
