Stamping and riveting mechanism

Abstract

The disclosure provides a stamping and riveting mechanism for riveting a first object and a second object. That is, integrating a first object in a riveting mechanism into a stamping die is to let the first object and the second object be riveted together during a stamping process. This reduces the need for transferring semi-finished products, decreases personnel and equipment requirements, so as to lower production costs. The stamping and riveting mechanism comprising a first stamping assembly and a second stamping assembly that are arranged up and down and parallel to a first direction. The first stamping assembly is disposed above the second stamping assembly, and the first stamping assembly is parallel to the first direction and moves corresponding to the second stamping assembly. The first stamping assembly provides a first object, and the second stamping assembly provides a second object.

What is claimed is: 
     
         1 . A stamping and riveting mechanism, comprising a first stamping assembly and a second stamping assembly that are arranged up and down and parallel to a first direction, the first stamping assembly being disposed above the second stamping assembly, the first stamping assembly being parallel to the first direction and moving corresponding to the second stamping assembly, the first stamping assembly providing a first object, the second stamping assembly providing a second object,
 the first stamping assembly comprising:
 a first stamping base; 
 a punch, having a first top end and a first bottom end that are corresponding to each other, the first top end being disposed at the first stamping base, the first bottom end, toward the second stamping assembly, being parallel to the first direction; 
 an unloading plate, disposed beneath the first stamping base; 
 a movable part, having a second top end and a second bottom end that are corresponding to each other, the movable part being movably disposed through the first stamping base and parallel to the first direction, the second bottom end being connected with the unloading plate, therefore the first stamping base being parallel to the first direction and moving corresponding to the unloading plate; 
 a plurality of guide pillars, each of the guide pillars having a third top end and a third bottom end, the third top end being disposed at the first stamping base, the third bottom end being toward the second stamping assembly, the guide pillars being movably disposed through the unloading plate and parallel to the first direction; 
 a loading device, comprising:
 a base, disposed at the unloading plate, having a first penetrating portion that is parallel to the first direction and through the base, the first bottom end of the punch being parallel to the first direction and extending into the first penetrating portion for moving in the first penetrating portion along the first direction; 
 a plurality of swing members, each of the swing members being disposed at the base via a pivot axis, the swing member symmetrically having two swing arms, a first swing arm and a second swing arm, based on the pivot axis, wherein the first swing arm is above the second swing arm; 
 a plurality of elastic members, an elastic direction of each of the elastic members being parallel to a second direction, two ends of the elastic member along the elastic direction being against the first swing arm and the base respectively, wherein the second direction is perpendicular to the first direction; 
 a plurality of positioning members, two ends of each of the positioning members along the second direction being a first end and a second end that are corresponding to each other, the first end being inserted into or withdrawn from the first penetrating portion, the second end being connected with the second swing arm; 
 a plurality of steel balls, each of the steel balls being disposed in the base and between the pivot axis and the positioning member, the steel ball moving between a release position and a push position, the partial steel ball being inserted into the first penetrating portion while the steel ball is at the release position, the steel ball being withdrawn from the first penetrating portion while the steel ball is at the push position; 
 a feed base, disposed on a bottom portion of the base, having a second penetrating portion, which is penetrated through the feed base along the first direction, the first penetrating portion and the second penetrating portion being allowed the first object to go through; and 
 the elastic member pushing the first swing arm outwardly while the steel ball is at the release position, the second swing arm driving the first end of the positioning member to insert into the first penetrating portion, the first end of the positioning member supporting the first object for keeping it in a suspended state; the steel ball being pushed outwardly while the punch passes through the steel ball, continuously, the steel ball pushing the second swing arm, so as to let the first end of the positioning member be withdrawn from the first penetrating portion, hence the first swing arm compressing the elastic member, the first object falling into the second penetrating portion from the first penetrating portion, finally to a top portion of the second object; and 
 
   the second stamping assembly comprising:
 a second stamping base, comprising a third penetrating portion and a plurality of guide holes, the third penetrating portion being through the second stamping base along the first direction, an axial direction of each of the guide holes being parallel to the first direction, each of the guide pillars being inserted into or withdrawn from the corresponding guide hole while the guide pillar moves along the first direction, the guide pillar being able to move in the guide hole along the first direction, the second stamping base being provided with a protrusion platform on each of its opposite sides, which are parallel to the second direction, and a recess being between the two protrusion platforms; and 
 a rivet base, disposed within the recess of the second stamping base, comprising a fourth penetrating portion, which is parallel to the first direction and through the rivet base, the third penetrating portion and the fourth penetrating portion allowing a sheared material to pass through, wherein the sheared material is the product after the first object and the second object are stamped and riveted. 
   
     
     
         2 . The stamping and riveting mechanism according to  claim 1 , wherein each of the swing members is assembled with the elastic member as one set, and each of the positioning members is assembled with the steel ball as another set, both sets being symmetrically disposed around peripheral of the first penetrating portion. 
     
     
         3 . The stamping and riveting mechanism according to  claim 1 , wherein a projection range of the first penetrating portion of the base falls within a projection range of the second penetrating portion of the feed base. 
     
     
         4 . The stamping and riveting mechanism according to  claim 1 , wherein the loading device comprises:
 a first detection element, disposed in the second penetrating portion, in order to detect whether the first object is in the second penetrating portion or not; and   a second detection element, disposed in the first penetrating portion, in order to detect whether the first object is in the first penetrating portion or not.   
     
     
         5 . The stamping and riveting mechanism according to  claim 1 , wherein a projection range of the third penetrating portion falls within a projection range of the fourth penetrating portion, the projection range of the fourth penetrating portion being equal to or greater than the projection range of the third penetrating portion. 
     
     
         6 . The stamping and riveting mechanism according to  claim 1 , wherein projection ranges of the first penetrating portion and the second penetrating portion cover a projection range of the third penetrating portion, projection ranges of the first penetrating portion and the second penetrating portion being greater than a projection range of the third penetrating portion.
