Problems solved by technology
Because the lower die of the progressive die is an integral module, the stamping surface of the module is provided with different cavities in different places according to the requirements of the product, so the processed steel strip receives uneven force during the stamping process, which is very easy to cause Each step deviation of the steel strip, or when the steel strip deviates during stamping, and an error occurs in the step of one end of the steel strip, it will cause batches of steel strip stamping products to be scrapped, so the stable step of the steel strip is very The essential

Embodiment
[0030] A feeding mechanism for a steel strip progressive die, see attached figure 1 And attached figure 2 , a progressive die is set on the punch press, the lower die of the progressive die is set on the table of the punch press, the upper die is set on the punch 11 of the punch press, and the opening and closing of the progressive die is realized during the up and down movement of the punch 11 Continuous stamping and forming of steel strips in the process. The feeding mechanism mainly includes a support rod 9 arranged on the feed end side of the punch press. On the support rod 9, a height-limiting transmission part, a width-limiting part, a material pulling part and a material pressing part are sequentially arranged, and the continuously conveyed steel belt passes through the The height-limited penetration of the height-limited transmission part, the eccentric transmission of the limited width direction of the width-limited part, and the step-by-step drawing transmission of...

The invention discloses a feeding mechanism of a steel strip progressive die. The feeding mechanism comprises a feeding bracket fixed horizontally on one side of the feeding end of a punching machine.A high limit material conveying portion for restricting the penetration height of a steel strip, a width limiting portion for preventing the steel strip from being deflected left and right in the conveying process, a material pulling portion capable of achieving accurate stepping of the automatic steel strip during the die opening and closing process of the progressive die and a material pressingportion used for preventing the progressive die from off tracking of the steel strip in the conveying direction during punch forming of the steel strip are sequentially arranged on the feeding bracket from the portion away from the punching machine to the feeding end of the punching machine. The feeding mechanism achieves the effect of accurate stepping of the steel strip in the punch forming process.
Description
technical field [0001] The invention relates to the field of moulds, more specifically, to a feeding mechanism for a steel strip progressive die. Background technique [0002] In one stamping stroke of the progressive die, processes such as stamping and blanking of different membrane cavities can be completed in sequence. Because the lower die of the progressive die is an integral module, the stamping surface of the module is provided with different cavities in different places according to the requirements of the product, so the processed steel strip receives uneven force during the stamping process, which is very easy to cause Each step deviation of the steel strip, or when the steel strip deviates during stamping, and an error occurs in the step of one end of the steel strip, it will cause batches of steel strip stamping products to be scrapped, so the stable step of the steel strip is very The essential. Contents of the invention [0003] In view of this, the object ...
