Hardware stamping processing manufacturers, the method of lifting and positioning stamping blanks [hardware]
Metal stamping manufacturers, in stamping production, will encounter inaccurate positioning when bending the blank. Generally it is because of the problem of blank sliding. Xiaoshuo will share with you how to improve positioning: 1. The ejector is composed of air cushion, rubber, spring, etc., through the top plate, the blank is reversed before the blank enters the bending Pressing force. In this way, the frictional force of the blank is increased and the possible movement of the blank is prevented. It is also possible to make tooth patterns, pits, top cones, etc. on the top surface of the pressing rod, the pressing plate or the working surface of the punch to increase the reliability of positioning. 2. Choosing a reliable positioning method There are mainly two types of positioning in the form of positioning and positioning in the inner hole. The shape positioning operation is convenient, but the reliability is poor. The inner hole positioning operation is not convenient enough, the use range is narrow, but the positioning is reliable. If the inner hole is used for positioning and the material pressing device is used, the positioning will have a better effect. 3. Asymmetry of the unqualified shape caused by the asymmetry of the blank will cause the blank to move due to the uneven force during bending. In order to make the blank bear uniform force during bending, asymmetrical workpieces can be combined into symmetrical workpieces, which can be bent once.
