Description
Technical field
The present invention relates to the processing method of auto parts and components, relate to the processing method of the buting iron on the automobile starter switch or rather.
Background technology
Existing buting iron all adopts the machining moulding, and its concrete steps are: step 1., round bar is cut off blanking through punch press, the length of blanking and end face diameter must be greater than the length and the end face diameters of the buting iron behind the finished product during blanking; Step 2., with blanking through the instrument lathe flat head chamfering; Step 3., become base substrate with the blanking after the flat head chamfering through the numerically controlled lathe machining; Step 4., with base substrate fine finishining, hole, reaming, turning, plane, chamfering, punching, turning, plane, chamfering once more, behind the jet-bedding, the buting iron final molding.Adopt this kind mode to process and have following defective: the length of blanking and end face diameter must be greater than the length and the end face diameters of the buting iron behind the finished product during blanking, when the processing base substrate, by numerically controlled lathe blanking is carried out the material that it is unnecessary that machining is pruned, waste to material is just bigger like this, and machining is consuming time many, influence production efficiency, also just increased production cost undoubtedly, reduced economic benefit.
Summary of the invention
The technical problem to be solved in the present invention is, providing a kind of can save material, and processes consuming time fewly, can improve production efficient, reduces production costs the processing method of the buting iron of increasing economic efficiency.
Technical solution of the present invention is, a kind of processing method of buting iron is provided, and it comprises following operation:
1., adopt the punch press blanking, the weight that the weight of blank equals cold extrusion shaped back base substrate behind the blanking adds the 2. weight of the allowance of step;
2., with the flat head chamfering on measuring truck of the blank behind the blanking;
3., the blank after the flat head chamfering is pressed into the product base substrate through the punch press cold-extruded;
4., the product base substrate that cold extrusion is formed is through NC instrument lathe boring, reaming;
5., the product base substrate after 4. step is handled is through numerically controlled lathe turning, plane, chamfering;
6., the product base substrate after 5. step is handled is through the punch press ball sizing;
7., the product blank after 6. step is handled is again through numerically controlled lathe turning, plane, chamfering;
8., the product blank after 7. step is handled is through punch press jet-bedding mouth, buting iron final molding.
The processing method of buting iron of the present invention compared with prior art has the following advantages:
Because blank is pressed into the product base substrate through the punch press cold-extruded, the weight that the weight of blank equals cold extrusion shaped back base substrate behind the blanking adds the 2. weight of the allowance of step so, the product base substrate need how much expect punch press with regard to the weight of the product base substrate that falls add 2. the weight of the allowance of step just can, length and end face diameter unlike machining blank when the blanking must be greater than the length and the end face diameters of product base substrate, a lot of unnecessary clouts of then will pruning again, save raw material by contrast greatly, thereby just reduced cost; The product base substrate is cold extrusion shaped, consuming time few by punch press, thereby has improved production efficiency of products, has also reduced production cost; The product base substrate has increased density metal, thereby has increased the intensity and the hardness of metal by the moulding of punch press cold-stamped mode, has also improved the quality of product.

The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
See also Fig. 1 to shown in Figure 9, the processing method of buting iron of the present invention comprises following operation:
1., adopt punch press that round bar is cut off blanking.Described punch press is the above punch press of 100T and 100T, and the weight that the weight of described blank equals cold extrusion shaped back product base substrate adds the 2. weight of the allowance of step, is converted into the volume of blank again according to the weight of blank behind the blanking.The diameter of described blanking is
Length is 37.3 ± 0.25mm.
2., with the flat head chamfering on measuring truck of the blank behind the blanking.Round bar is after punch press cuts off blanking, and the blank head can be jagged, can make blank can not put into mould, after the measuring truck flat head chamfering, can pare off the burr of blank head, makes blank successfully put into mould, and at this moment, the diameter of described blank becomes
