Abstract

The invention provides a forming machine and a forming method of a metal material, and the manufacturing method of a stopping claw part. The problem that a mandrel is prevented from being locally damaged or degraded locally caused by accumulative strike of a punch when the mandrel is provided with an easy-to-damage part is solved. The forming machine (92) comprises the mandrel (110) and more thanone punch (130), wherein more than one mandrel projection (30) extends in the axial direction; and more than one punch (130) are arranged on the periphery of the mandrel (110), and more than one bending part is formed in the metal material (80). The mandrel (110) comprises a first mandrel part (1) and a second mandrel part (20) which are separated from each other and are arranged in a mode of being in contact with each other. At least one of the first mandrel part (1) and the second mandrel part (20) is provided with the mandrel protrusion.

Description

technical field [0001] The present invention relates to a forming machine, a forming method of a metal material, and a manufacturing method of a stop pawl member. Background technique [0002] Patent Document 1 discloses a molding machine for a stop claw member of a slide fastener slider. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: International Publication No. 2015 / 128996 Contents of the invention [0006] As can be seen from the examples in Patent Document 1, during the continuous molding of a metal material in a molding machine, the mandrel continues to receive impact from the punch. When the mandrel has a portion that is easily broken, there is a problem that the mandrel is partially damaged and / or deteriorated due to the accumulation of impacts from the punch. [0007] One aspect of the present invention relates to a molding machine including: [0008] a mandrel having one or more mandrel protrusions extending axially; and ...
