Description
Technical field
The present invention relates to a kind of suspension hook processing technology, especially relate to a kind of suspension hook porous processing technique for hoisting machinery.
Background technology
At present, in production hoisting machinery lift hook porous processing process, the bore process generally adopted first on drilling machine, bores one of them hole, and then with boring through lathe, after hole bores, locate with this hole, drilling machine gets out another hole, use boring through lathe again, need two lathes, two cover frocks, and need No. four clampings.This technique has obvious shortcoming, is summarized as follows:
A, two lathes: this technique needs to take two lathes, this is a kind of invisible waste.The lathe saved can be used in the processing of other products, increases the processing and manufacturing ability of production line.The operator's operation of original needs, become now two people, such company needs how to pay wage to workman, increases enterprise operation cost.
B, two cover frock, No. four clampings: workpiece No. four clampings have several shortcoming:
One, machining accuracy will certainly be caused like this to reduce, when bore hole, the center in hole can partially, cause axiality bad;
Two: cutter needs polygamy, so also increase the wearing and tearing of cutter, cause processing cost to increase;
No. three: four times clamping equally also increases machining time, and production efficiency declines.
Summary of the invention
Object of the present invention be exactly provide that a kind of production efficiency is high to overcome defect that above-mentioned prior art exists, technique is simply for the suspension hook porous processing technique of hoisting machinery.
Object of the present invention can be achieved through the following technical solutions:
For a suspension hook porous processing technique for hoisting machinery, a machining center is processed, and frock only needs a set of, and concrete technology is as follows:
(1) by clamping workpiece on lathe, drill bit is fixed on machine tool chief axis, then starts lathe, machine spindle speed 600-800r/min, move with the speed of 5-8mm/s, by drill bit near workpiece, with F=0.1-0.2 millimeter/turn feed speed start to bore bottom outlet;
(2), after bottom outlet bores, drill bit is return with the speed of 5-8mm/s;
(3) den bohrkopf abbauen, clamping hole boring cutter, is transferred to 800-1000r/min by machine spindle speed, opens cutting fluid, opens lathe button, and lathe runs automatically with the feed speed of F=0.1-0.2 millimeter/turn, processing bore hole.
Treat program finishes execution, workpiece only need take off by operator, do not need with two lathes dismantle back and forth, clamping, which reduces clamping times, improve operating efficiency.
Carbide alloy knife bar selected by the knife bar of described hole boring cutter, and such arbor stiffness is good, can ensure the quality of product.
Described cutting fluid adopts model to be the cutting fluid of SPH-39.
As preferably, when boring bottom outlet in step (1), machine spindle speed is 700r/min, moves with the speed of 6mm/s, by drill bit near workpiece, starts to bore bottom outlet with the feed speed of F=0.15 millimeter/turn.
As preferably, in step (2), after bottom outlet bores, drill bit is return with the speed of 6mm/s.
As preferably, in step (3), machine spindle speed is transferred to 900r/min, opens cutting fluid, open lathe button, lathe runs automatically with the feed speed of F=0.2 millimeter/turn, processing bore hole.
Compared with prior art, the present invention has the following advantages:
1, technique is simple, and only need an operation card, operator also easily identifies;
2, processing cost is low, and original needs two lathes, are first only needing one, save cutting fluid, the electricity charge etc.;
3, become work rate high, clamped one time can wrap the machining accuracy of positive workpiece;
4, librarian use is few, and original needs two operators, only need a people now:
5, working (machining) efficiency is high, does not need repeated clamping, dismounting, saves a large amount of time;
6, production efficiency is high, is suitable for various batch production;
7, NC postprocessing degree is high, alleviates the labour intensity of operator.
