  • Patent number: 8371150
    Abstract: Provided is a forming die, including a movable supporting member, a movable die, a fixed supporting member and a fixed die. The movable supporting member disposes an oblique sliding groove. The movable die disposes an oblique guiding surface engaged with the oblique sliding groove. The movable die disposes a forming portion, which includes a forming base and a protruding portion extending downward from the forming base. The movable die can tilted move along the oblique sliding groove. The fixed die disposes a flange having a high point. The forming die of the present invention employs the movable die tilted moving along the oblique sliding groove to make the protruding portion extend into the back space of the high point, so that no gap exists between a bending portion of a terminal and the flange for obtaining the bending portion having a large bending degree and having a stable size.

  • Publication number: 20120324977
    Abstract: A stamping tool for stamping a product having a base plate and a contact arm includes an assistant block, a supporting element assembled in the assistant block, a molding floater slidably mounted to one side of the assistant block and a pressing element driving the molding floater to slide downward to secure the base plate therebetween. A plurality of resisting sections are formed on a top of the supporting element and stretched beyond a top of the assistant block. A top of the molding floater extends to form a bending board suspended over the resisting sections. A molding punch is movably inserted in the pressing element with a bottom end thereof projected out of the pressing element for making the contact arm pass through two corresponding resisting sections to be bent towards a bottom of the bending board, wherein the resisting sections resist against the bottom of the bending board.

  • Publication number: 20120312068
    Abstract: A stamping tool for stamping a product having an extending portion includes an upper mold having an inserting punch of which a bottom end defines an inclined pressing surface exposed under the upper mold, and a lower mold including an adjusting element, a sliding block, a returning block, a returning bolt and an elastic element. The returning bolt is inserted in the elastic element, and then screwed in the sliding block through the returning block. The sliding block is slidable between the returning block and the adjusting element and has one corner provided with an inclined abutting surface. The inclined pressing surface presses the abutting surface to push the sliding block and the returning bolt to slide towards the adjusting element so as to make the extending portion clipped between the sliding block and the adjusting element for modulating the product.
