High precision punching die

Abstract

The invention discloses a high precision punching die. The high precision punching die comprises an upper die (1) and a lower die (2), wherein the upper die (1) and the lower die (2) are correspondingly arranged; the upper die (1) comprises an upper die seat (3), an upper padding plate (4) and a stripper plate (7) in sequence; the lower die (2) comprises a lower die plate (8), a lower padding plate (9) and a lower die seat (10) in sequence. The high precision punching die is characterized in that a feed trough (12) is formed in the surface of the lower die plate (8) in the length direction, and a plurality of horizontal rollers (14) perpendicular to the moving direction of a material belt are arranged in the feed trough (12) at equal intervals. The high precision punching die is high in punching precision.

Description

technical field [0001] The invention relates to a punching die, in particular to a high-precision punching die. Background technique [0002] At present, the punching die is generally composed of a punch and a die, and can also be composed of multiple punches and multiple dies, but only one punching process can be completed in one stroke of the punching machine. When the shape of the part is complex, it needs to be composed of more than one single-engineering punching die to produce a qualified product. This kind of mold is not only insufficient in stability, but also wastes manpower cost and mechanical cost. [0003] The Chinese patent authorization announcement number is CN203900258U, and the utility model patent with the authorization announcement date on October 29, 2014 discloses a continuous mold for connecting cushion covers, including an upper mold base and a lower mold base, and is arranged on the upper mold base and the lower mold. The first punching die, the sec...

Problems solved by technology

Although the utility model can produce the connection pad cover at a faster production speed, it can be seen that it can effectively reduce labor costs and mechanical costs, reduce the reject rate of the product, and it can be seen that it has high stability, but it has been found in long-term use. During the punching process, because the material belt is constantly advancing, it is easy to jump, which can easily lead to the displacement of the material belt, which is easy to cause punching errors. Therefore, it is very important to prevent the material belt from jumping during the punching process.
