Bending machining method for duplex turbine blade locking plate

Abstract

The invention provides a bending machining method for a duplex turbine blade locking plate. The bending machining method comprises the following steps of (1), selecting two stainless steel plates withthe thickness being 1.5 mm; (2), chamfering C0.5 into the upper and lower ports of the joint of the two plates, and then carrying out roll welding; (3), carrying out linear cutting machining in the metal streamline direction to obtain the length and the width of the duplex turbine blade locking plate; (4), pre-bending the head of the turbine blade locking plate through opening machining by a bench worker; and (5), taking the other end as a benchmark, placing the machined pre-bent part in a lower die of a bending die, and carrying out final bending forming machining on the pre-bent part of thehead to obtain a finished product. According to the method, a bending forming die and a bending forming machining process method are adopted, the process method is simple, die positioning is controllable, the product size is good, the appearance quality is high, the surface quality of a bent product is good, machining is stable and reliable, the production cost is greatly saved, the die manufacturing cost period is shortened, and the bending forming die is suitable for large-batch production.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a bending processing method of a double-connected turbine blade locking piece. Background technique [0002] Duplex turbine blade locking plate is a special part, which has a large number, complex shape, high requirements, difficult processing, and frequent failure parts, so its manufacturing and processing has always been the key link of various production and processing enterprises. [0003] The commonly used process for bending the existing double-connected turbine blade lock piece is: use a mold with a guide post for bending, use the mold for processing, and then weld the left and right pieces together. Using the traditional method, the blade head is prone to large scratches and strains, the production cost of the mold is high, and the service life of the mold is short, and the product failure rate is high. Contents of the invention [0004] In view of this, the present...
