Embodiment 1
[0015] like figure 1 In the joint installation mold shown, two sets of molds are installed on the lower backing plate 1, one set of molds is a drawing forming mold 2, and the other is a trimming and turning mold 3; wherein the drawing forming mold 2 is If an air cushion is required, the press air cushion 8 transmits the power to the auxiliary mold through the air cushion ejector pin 4, that is, the blank holder 5, which provides the blank holder force during the forming process, so that the die 22, the punch 23 and The blank holder ring 5 is used for drawing and blanking. On the other side, the punching and turning mold 3 does not need an air cushion, but in this case, the air cushion 8 of the press is more eccentric, and long-term production will cause greater damage to the air cushion, which will lead to poor press precision and lower product quality. Instability and other quality risks.

The invention provide a method for balancing loads during mold production, which aims to solve the problem that jointly-mounted mold air cushions are influenced by unilateral loads so as to protect the air cushions of pressing machines and improve the effective using pressure of the pressing machines and the quality stability of workpieces. The method for balancing the loads during mold production comprises the following steps that: a drawing formation mold and a repairing, punching, turning and reshaping mold are arranged on the same operating platform; a binder ring of the drawing formationmold is pressed against an air cushion push rod which passes through the drawing formation mold from bottom to top; in the key point, a balancing rod is arranged between an upper die and a lower die of the repairing, punching, turning and reshaping mold; the bottom of the balancing rod is pressed against a balancing push rod which passes through the lower die of the repairing, punching, turning and reshaping mold from bottom to top; and the air cushion push rod and the balancing push rod have the same travel and are moved synchronously. By the method for balancing the loads during mold production, the problem of unbalanced loading of the air cushions of the pressing machines is effectively solved by using the balancing rod; and the method is extremely high in practicability.
Description
technical field [0001] The invention belongs to the technical field of molds, in particular to a method for balancing loads in mold production. Background technique [0002] In the stamping process design process, due to the complex shape of the stamped parts and the many irregular shaped parts, the eccentric structure of the air cushion is often used. In addition, since various companies have begun to use large-table presses to produce large-scale parts, or to improve production efficiency through joint installation (joint installation means installing two or more sets of molds on one press at the same time), At this time, the phenomenon of eccentricity in mold installation is more common. The above situation will bring the following three bad hidden dangers: 1. The air cushion of the press is easily damaged due to the unilateral load on the press equipment; 2. The effective use pressure of the press is reduced; 3. The quality of the workpiece is unstable. Contents of t...
