Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold processing technology, and in particular to a quick change device for punch forming molds. Background Technology
[0002] As a key piece of equipment in the metal processing field, punch presses are widely used in numerous industries such as automobile manufacturing, electronic equipment production, and hardware processing. They apply pressure to sheet metal using molds, causing plastic deformation or separation to produce parts of various shapes. In automobile manufacturing, a large number of parts, such as body panels and structural components, are formed by punch presses; in electronic equipment production, mobile phone casings, computer cases, and other components also rely heavily on punch press processing. The high efficiency and processing precision of punch presses play a vital supporting role in the development of the manufacturing industry.
[0003] The traditional process of changing punch press dies is very complicated. First, the operator needs to use tools to loosen the bolts, nuts and other connecting parts that fix the die. Then, the old die is carefully lifted out of the punch press working area by a crane or other lifting equipment. The new die is then lifted in and initially positioned. This process is quite troublesome and wastes a lot of time. At the same time, it is inconvenient for a forklift to place the die on the punch press during the die placement process.

[0014] (III) Beneficial Effects
[0015] This utility model provides a quick-change device for punch press forming dies, which has the following beneficial effects:
[0016] 1. This quick-change die changing device for punch presses, through the arrangement of a push assembly, a die-shifting assembly, and a support assembly, activates a lifting hydraulic rod during use. The lifting hydraulic rod moves a lifting plate, aligning the second pulley with the first pulley, placing the die on the support plate. The die is then pushed onto the lifting plate, and the lifting hydraulic rod descends to place it on a placement plate for stamping. After stamping is complete, the push hydraulic rod is activated again, moving a push plate, which in turn moves the die. This allows for rapid removal and insertion of the die from the punch press worktable, reducing waiting time during die changes and improving production efficiency.
[0017] 2. This quick-change die changing device for punch presses, through the setting of positioning components and electromagnetic plates, activates the servo motor when the die is pushed to the bottom of the punch press body. The rotation of the servo motor drives the threaded rod to rotate, and the rotation of the threaded rod causes the push plate to move on the threaded rod. The push plate positions and clamps the workpiece. After positioning and clamping, the electromagnetic plate is activated, and the electromagnetic plate generates a suction force to fix the die, thereby making the device more stable during use.
