Apparatus for separating micro-joint processed products and die used therefor

Apparatus for separating a product from a skeleton portion of a workpiece at a micro-joint which joins the product to the skeleton portion of the workpiece and which is located directly adjacent to the product, comprising:

• a punch provided with a projecting portion at an end thereof and movable up and down;
• a die arranged with said punch and provided with an elastic substance;
• aligning means for moving the workpiece in two directions in a plane of the workpiece until said die is aligned with said punch and said elastic substance is positioned opposite to said projecting portion of said punch;
• and
• means for moving said projecting portion so that said projecting portion pushes said skeleton portion at a point adjacent to said micro-joint without contacting said micro-joint or said product, said punch and die being positioned relative to said skeleton portion by said aligning means such that said product is separated from said skeleton portion by pushing said skeleton portion adjacent to said micro-joint without contacting said micro-joint or said product.

Apparatus for separating a skeleton portion of a workpiece from a product at a micro-joint which joins the product to the skeleton portion of the workpiece, and which is located directly adjacent to the product, said apparatus comprising:

• punch means including a projecting portion for moving toward and impacting the skeleton portion of the workpiece;
• a die disposed under said punch means, said punch means and said die defining a work position therebetween;
• aligning means for moving the workpiece in two directions in a plane of the workpiece until said die is aligned with said punch and a specific part of the skeleton portion of the workpiece in close vicinity of the micro-joint is located just over the die and just under the projecting portion of the punch;
• and
• moving means for moving said punch means toward said die;
• wherein said projecting portion pushes said specific part of said skeleton portion without contacting said micro-joint or said project, thereby causing said product to be separated from said skeleton portion of said micro-joint.

Apparatus for separating a product connected to a skeleton portion of a workpiece at a micro joint which is located directly adjacent to said product, comprising:

• a punch provided with a projecting portion at an end thereof and movable up and down;
• a die arranged under said punch and formed of an elastic substance;
• aligning means comprising work clamps for clamping the workpiece so as to move the workpiece in two directions in a plane of the workpiece until a specific part of the skeleton portion in close vicinity of the micro joint is located just over the die and just under the projecting portion of the punch;
• and
• means for moving said projecting portion so that said projecting portion pushes said skeleton portion at a point adjacent to said micro-joint without contacting said micro-joint or said product, said punch and die being positioned relative to said skeleton portion by said aligning means such that said product is separated from said skeleton portion by pushing said skeleton portion adjacent to said micro-joint without contacting said micro-joint or said product.
