Description

Technical Field

[0001] The utility model relates to the technical field of pressing machines, in particular to a multi-station pressing machine for malleable cast iron castings. Background Art

[0002] Malleable cast iron is commonly known as malleable iron. The production process of malleable iron is: first, it is cast into white cast iron parts, then it is subjected to forgeable annealing (forgeable annealing decomposes cementite into flocculent graphite) to obtain forgeable cast iron parts, and then it is pressed into shape through a pressing process. A pressing machine is required to press malleable cast iron castings.

[0003] Among them, in order to improve the pressing efficiency, a multi-station pressing machine is often used to press malleable cast iron castings in actual use. For example, the utility model patent with publication number CN218340766U discloses a malleable cast iron casting pressing machine, which includes a bottom plate and a U-shaped bracket fixed on the top surface of the bottom plate, two cylinders are symmetrically fixed on both sides of the top bottom surface of the U-shaped bracket, and the output ends of the two cylinders are fixedly connected to a cross plate, and a plurality of equidistantly distributed lower pressing blocks are fixed on the bottom surface of the cross plate, and a fixed block is provided between two adjacent lower pressing blocks; The utility model provides a locking mechanism in the lower pressing block. When the workpiece to be processed is placed in the die cavity, the fixed block above the die cavity can be locked accordingly, so that when the cross plate is driven by the cylinder to move downward, only the locked lower pressing block can drive the fixed block to move downward, that is, the fixed block drives the bottom punching plate to punch downward, and then the cylinder drives the cross plate to move up, while other workpieces can continue to be punched in other die cavities for the next time, which is convenient for workers to take out the workpiece that has just been punched from the die cavity, and can complete the pressing and taking out of multiple workpieces at the same time, thereby improving the processing efficiency.

When one of the pressing heads is damaged, the multiple pressing heads need to be replaced at the same time, which increases the processing cost. Utility Model Content
