Integrated forming and processing system for coiled shell body and processing method thereof

Abstract

The invention discloses an integrated forming and processing system for a coiled shell body. The integrated forming and processing system comprises a machine frame, a feeding device, a blanking device, a bending device, a rounding device, a discharging device and a conveying belt, wherein the feeding device, the blanking device, the bending device, the rounding device, the discharging device and the conveying belt are mounted on the machine frame; the feeding device is used for conducting steel belt positioning adjustment and flattening feeding, a steel belt is conveyed to the blanking devicethrough the conveying belt to be cut and punched to form a sheet-type plate, and then the sheet-type plate is conveyed to the bending device through the conveying belt; and a six-azimuth punch is adopted to be matched with a core rod to bend the sheet-type plate to form a circular semi-finished product, and then the circular semi-finished product is sent to the rounding device to synchronously extrude and round through rounding blocks in four directions, so that a circular rolling shell body is formed, and the round winding shell is discharged through the discharging device. According to the integrated forming and processing system, the automatic machining equipment is adopted to be matched with the three-time machining process to realize the machining of a high-precision rolling bushing.

Description

technical field [0001] The invention relates to the field of rolled shells, in particular to an integrated forming processing system and a processing method for rolled shells. Background technique [0002] In the production and assembly of auto parts, the solenoid valve is one of the most important parts, and the housing products are one of the most important parts of the solenoid valve. [0003] There are mainly three types of existing coil shell processing techniques, including metal cutting, stretch stamping and coil stamping. Among them, the main raw material for metal cutting is seamless steel pipe, and the process is relatively complicated, involving the machining process of turning shape, boring inner hole, milling notch, grinding end face and cutting. The complex length process leads to low overall production efficiency, and the whole production The process involves more equipment, so the production cost is relatively high. For the stretch stamping process, multi-pa...

Among them, the main raw material for metal cutting is seamless steel pipe, and the process is relatively complicated, involving the machining process of turning shape, boring inner hole, milling notch, grinding end face and cutting. The complex length process leads to low overall production efficiency, and the whole production The process involves more equipment, so the production cost is relatively high. For the stretch stamping process, multi-pass stretching is performed through a multi-station progressive die or transfer die, and then the notch stamping operation is performed. The entire process There are many steps, the cost of mold development is high, and the precision (roundness) of the stretching operation is difficult to control, which cannot meet the requirements of high precision. Roll stamping is to stamp the curled plate through a stamping machine to form an approximately round shape. The rough product, and then insert a cylindrical rod inside the rough product, and the processor manually beats the outside of the bush to make it round, and the inner diameter value is close to the processing requirements, and finally the two ends of the bush are turned by a lathe to make the bush height approximate to the processing Value, this method is traditional manual processing, not to mention its very low processing efficiency, the precision of the bushing processed by this processing method is very low, its inner and outer diameter values, roundness, roughness, verticality of the cut surface and levelness of the cut surface It is difficult to control accurately, and it can only be suitable for customers who do not require high machining accuracy, but for customers with high machining accuracy requirements, this method cannot satisfy the requirements at all.
