Description
Technical field
The present invention relates to the processing technology of wheel tyre bending die.
Background technology
In the production process of wheel-tyre, cold stamping has become a kind of advanced person's processing method, and bending die also uses thereupon in a large number.The present process of bending die is: the cylinder blank is after processing endoporus, curve on general car, and chamfering bit goes out the hole on mould.This processing method has the shortcoming of the following aspects: the one, and allowance is large, and the processing on endoporus, circular arc inclined-plane need to slattern many materials; The 2nd, crudy is difficult to guarantee, during with general Vehicle Processing circular arc inclined-plane, needs manually to use continually model to proofread check, adjusts the process of processing, can not guarantee exactly crudy; The 3rd, working (machining) efficiency is low, and the operations such as general car, artificial check and correction check adjustment processing, chamfering bit make process time longer, and speed is slower.
Summary of the invention
Problem to be solved by this invention is to provide a kind of processing technology of wheel tyre bending die, and it both can guarantee the crudy of bending die, can raise the efficiency again.Simultaneously, this technique can also reduce the loss of material.
The processing technology of wheel tyre bending die of the present invention, concrete steps are:
1) mold pressing: will justify the base forging and put into the blank mould, will justify the base oil pressure and become mould base shape on hydraulic press, the monolateral surplus 5mm of putting;
2) numerical control lathe: clamping d1 arc end is proofreaied and correct, facing H1, cylindrical d2, endoporus D1, and cylindrical d2 is put surplus 6mm, and endoporus D1 is put surplus 6mm;
3) numerical control lathe: transfer face clamping d2 to proofread and correct, facing H2, cylindrical d1, cylindrical d1 is put surplus 6mm, car R1 circular arc inclined-plane, the monolateral surplus 3mm of putting, total height L1 is put surplus 6mm;
4) heat treatment: HRC38-42
5) numerical control lathe: clamping d1 arc end is proofreaied and correct, facing H1 and chamfering, and turning d2, endoporus D1 are to size;
6) numerical control lathe: transfer face clamping d2 to proofread and correct, facing H2 and chamfering, turning d1, R1 circular arc inclined-plane guarantees size L1, L2 to size;
7) bore: process uniform D2 hole;
8) shaping: to each corner angle burr of workpiece repair, oiling;
9) check.
The advantage of processing technology of the present invention is: one, with numerical control replacement artificial circular arc inclined-plane: by employing lathe in machining circular arc inclined-plane, guaranteed the quality of processing, improved operating efficiency; Two, replace artificial line boring with mould; By drill jig, the hole is processed, guaranteed the quality of processing, improved operating efficiency; Three, changing the cylinder blank is the pressing mold blank; The pressing mold blank is compared with last finished product, the monolateral surplus of only having 5mm, and original endoporus, circular arc inclined-plane is all solid, need to process, so the allowance of blank reduces greatly.In a word, processing technology of the present invention has alleviated mechanical loss, shortens process time, has guaranteed crudy, has improved operating efficiency, greatly reduces production cost.

Fig. 1 is the schematic diagram of bending die.
The specific embodiment
The processing technology of wheel tyre bending die of the present invention, concrete steps are:
1) mold pressing: will justify the base forging and put into the blank mould, will justify the base oil pressure and become mould base shape on hydraulic press, the monolateral surplus 5mm of putting;
2) numerical control lathe: clamping d1 arc end is proofreaied and correct, facing H1, cylindrical d2, endoporus D1, and cylindrical d2 is put surplus 6mm, and endoporus D1 is put surplus 6mm;
3) numerical control lathe: transfer face clamping d2 to proofread and correct, facing H2, cylindrical d1, cylindrical d1 is put surplus 6mm, car R1 circular arc inclined-plane, the monolateral surplus 3mm of putting, total height L1 is put surplus 6mm;
4) heat treatment: HRC38-42
5) numerical control lathe: clamping d1 arc end is proofreaied and correct, facing H1 and chamfering, and turning d2, endoporus D1 are to size;
6) numerical control lathe: transfer face clamping d2 to proofread and correct, facing H2 and chamfering, turning d1, R1 circular arc inclined-plane guarantees size L1, L2 to size;
7) bore: process uniform D2 hole;
8) shaping: to each corner angle burr of workpiece repair, oiling;
9) check.
The advantage of processing technology of the present invention is: one, with numerical control replacement artificial circular arc inclined-plane: by employing lathe in machining circular arc inclined-plane, guaranteed the quality of processing, improved operating efficiency; Two, replace artificial line boring with mould; By drill jig, the hole is processed, guaranteed the quality of processing, improved operating efficiency; Three, changing the cylinder blank is the pressing mold blank; The pressing mold blank is compared with last finished product, the monolateral surplus of only having 5mm, and original endoporus, circular arc inclined-plane is all solid, need to process, so the allowance of blank reduces greatly.In a word, processing technology of the present invention has alleviated mechanical loss, shortens process time, has guaranteed crudy, has improved operating efficiency, greatly reduces production cost.
