The utility model relates to a kind of perforating press that the washing machine bottom is punched.
At present the washing machine bottom is carried out punching and mainly adopt two kinds of methods, a kind of is manually to use power drill boring, and another is to use the punch press punching, because it is many that bottom need punch, not only efficient is low so adopt said method, and can't guarantee the precision of punching to occur the part of doing over again easily.
The utility model content
The purpose of this utility model provides a kind of perforating press, solves how efficient, that accurately bottom is punched at present technical problem.
The technical scheme that its technical problem that solves the utility model adopts is:
Perforating press comprises bottom jig, hold-down mechanism, punch mechanism, hydraulic system; Have on the bottom jig and the corresponding projection of washing machine bottom groove, hold-down mechanism and punch mechanism link to each other with hydraulic system, hold-down mechanism shows triangle and is arranged on around the bottom jig, being arranged between two hold-down mechanisms of each punch mechanism correspondence, the punch mechanism termination has punch.
The beneficial effects of the utility model are, owing to adopt HYDRAULIC CONTROL SYSTEM hold-down mechanism and punch mechanism, and fully automatic working like this, one-shot can be finished punch work.

The specific embodiment
Please refer to Fig. 1 and Fig. 2, the perforating press of present embodiment includes the hold-down mechanism 2 of the bottom jig 1 that makes washing machine bottom 4 location, fixed bottom cover, the perforating mechanism 3 that bottom is punched, the hydraulic system 5 that drives the said mechanism motion.
Washing machine bottom 4 has three road grooves, and what 120 degree at interval between these grooves, bottom jig 1 adopted the cnc profiling correspondence also is processed with three projectioies, and positioning bottom cap 4 like this.Three hold-down mechanisms 2 are carried out interlock by hydraulic system 5 and are compressed bottom 4, and just as similar lathe clamping work pieces, three punch mechanism 3 terminations have the punch of punching, and this punch mechanism 3 also is subjected to the control of hydraulic system 5 to do back and forth movement.
The job order of bottom 4 punchings is as follows: at first bottom 4 is placed on the bottom jig 1, hydraulic system 5 drives hold-down mechanism 2 workpiece pressings then, and at this moment 6 pairs of bottoms 4 of the punch of punch mechanism 3 punch.
