Tailing feeding device for multi-station progressive mould and working method for tailing feeding device

Abstract

The invention provides a tailing feeding device for a multi-station progressive mould. The tailing feeding device comprises an upper mould part, an unloading part and a lower mould part. The tailing feeding device is characterized in that the upper mould structure comprises an upper mould base (1), a limiting post (3), an upper gasket (4), a first guide post (5), a convex mould (8) and an inner force transmission assembly (10); the unloading part comprises an unloading plate base (6), an aligning pin (7), a small unloading plate (9), an inner guide post (11) and an outer force transmission assembly (12); and the lower mould part comprises a concave molding board (13), a lower mould base (14), an inner guide post sleeve (15), an inverted aligning pin hole (16), and an outer guide post sleeve (17). The tailing feeding device can realize transmitting and processing utilization of residual tailings, ensures reliability and stability of a mould working process on the basis of guaranteeing strip stamping precision, and can be widely applied to follow-up processing utilization of residual tailings of various multi-station progressive moulds.

Description

technical field [0001] The invention relates to a mold technology, in particular to a tail material feeding device of a multi-station progressive mold and a working method thereof. Background technique [0002] In recent years, the pressure of energy demand has continued to grow. The development of nuclear power has become an important direction for the adjustment of energy structure in countries around the world. The construction of nuclear power plants in my country is also developing rapidly. It is imperative to master the construction of independent nuclear power plants. In order to achieve independent nuclear power, it is necessary to design It belongs to my country's own nuclear fuel assembly. As an important part of the nuclear fuel assembly, the ribbon has great engineering application value in designing the structure of the mold for punching the ribbon. my country has designed a high-precision progressive blanking die for the punching of nuclear fuel assembly strips...

Problems solved by technology

However, after a lot of tests and production and processing practices, it is known that when a turn of strip material (zirconium alloy and other materials) is processed to the last section, the tail end of the strip material is separated from the feeder, and the feeding mechanism at the front end of the mold will not be able to continue to convey this section of tail material. At this time, a whole tail material (about 1m in length) between the feeder and the mold will become waste because it cannot be conveyed forward, resulting in waste of material
