Quality requirements for stamping parts in stamping parts factory

  The quality requirements of metal stamping parts are very strict in the stamping parts factory. So we must strictly control the shape and size of stamping parts: first of all, the requirements of bending parts: the shape of bending parts should be as symmetrical as possible, bending radius can not be less than the allowable small bending radius of materials. The curved edge is too short to form, so the flat part H>2 delta of the bent edge should be made. If H is required to be very short, an appropriate allowance should be set aside to increase H, and the additional metal should be removed after bending. When the hole is bent, the deformation of the hole is avoided. The shape of the metal stamping parts should be simple and symmetrical, and the depth should not be too large. So that the drawing times are few and easy to form. The fillet radius of metal stampings does not increase the technological procedure. Otherwise, it will increase the frequency of drawing, increase the number of moulds, and produce waste products and increase costs.

  Is the heat treatment intensity of Dalian stampings lower than that before heat treatment? The answer to this question is not necessarily because the key depends on the heat treatment process, mainly the heat treatment temperature. Generally speaking, the brittleness of metals will increase after cold stamping. Therefore, heat treatment or blackening is used to improve the plasticity of stamping parts. If it is a low temperature process, then its strength is reduced, but if it is annealed at high temperature, it will not have a great impact.

  How should the quantity of stamping process be determined? Generally speaking, the number of stamping processes refers to the same nature of the process, the number of repeated. Therefore, on the premise of guaranteeing the quality of stamping parts, the number of working procedures should be reduced as far as possible, so as to improve the production efficiency of the workpiece and improve its economic benefits. Moreover, this requirement should be strictly enforced and should not be slackened to ensure the above effect.
