Problems solved by technology
from figure 1 It can be seen that when the material belt is long enough, the feeder can push the material belt to move forward during punching, so as to realize the automatic feeding of the material belt during the punching process; when the material belt is punched to the tail part, The feeder cannot continue to provide power for the belt transmission. At this time, the material belt cannot continue to move forward, and the punching action of the mold cannot realize the forward movement of the belt material. At this time, the entire punching process cannot continue, and it will waste of material

The invention discloses a hook-type material-pulling material belt conveying device capable of realizing zero tailing punching. The device comprises a hook-type material-pulling portion, a sensing portion and a cutoff portion, the hook-type material-pulling portion comprises a material pulling hook (7), a wiredrawing spring (8), a cylindrical pin (9), a wedge mechanism (10), a moving slider (11), a guide rail plate (12), a resetting spring (15) and a guide rail groove (16), the sensing portion specifically comprises an electromagnetic valve (1), an upper die base accessory structure (2), a sensor (3), a material-pulling hook press head (4) and a spring (5), and the cutoff portion specifically comprises a cutoff convex die (13) and a cutoff concave die (17) and is used for cutting off a tailing (6). By the device, a tailing portion of a material belt can be utilized fully in the process of die punching, and material waste is avoided while stability and reliability during punching are guaranteed, so that cost is saved in the process of producing parts on a large-scale and in batches.
Description
technical field [0001] The invention relates to a mold technology, in particular to a material belt conveying device capable of realizing punching without tail. Background technique [0002] In recent years, under the pressure of continuous growth in energy demand, the safe development of nuclear power has become an important direction for the adjustment of energy structure in all countries in the world, which has made great progress in the construction of nuclear power plants in my country. Special strips are an important part of nuclear fuel assemblies, and their material costs are expensive. Due to the limitations of the structure of the mold itself and the feeding device, ordinary strip blanking dies will lead to waste of tailings. Therefore, for the strip conveyor The design of tailless punching has great engineering application value, and also meets the needs of my country's further development of the nuclear power industry. [0003] The schematic diagram of a common m...
