Abstract
The utility model discloses a punching mechanism of a pneumatic quick cold-punching machine. The punching mechanism of the pneumatic quick cold-punching machine comprises an adjusting fixing rod, a first connecting rod, a second connecting rod, a third connecting rod, a movable slider seat, a die-punching device, a punching steam cylinder, a steam cylinder mounting seat and connecting pins, wherein one end of the adjusting fixing rod is movably connected with one end of the first connecting rod through a connecting pin; the other end of the first connecting rod is movably connected with one end of the second connecting rod and one end of the third connecting rod through connecting pins; the other end of the second connecting rod is movably connected with the movable slider seat through a connecting pin; the die-punching device is arranged on the front end surface of the movable slider seat; the other end of the third connecting rod is fixedly connected with a piston rod of the punching steam cylinder through threads; and the punching steam cylinder is arranged on the steam cylinder mounting seat through a screw. By the mode, the punching mechanism is simple and practical in designed structure; the punching forming force is increased through a force-doubling steam cylinder; the retention degree of the punching forming force is increased by using mechanical dead points; a punch die is prevented from moving backwards; and moreover, the punching mechanism is pollution-free.
Description
Technical field
The utility model relates to a kind of lathe and makes the field, particularly relates to a kind of punching mechanism of pneumatic quick cold punching machine.
Background technology
In the manufacturing of automobile, can use a lot of metal tubes, comprising air-conditioning duct and braking automobile pipeline etc.The specific shape that all needs the interface of these pipes satisfies the needs that connect; need the cold punching machine and process these pipes; common production all adopts hydraulic jack as the action energy with the cold punching machine; hold the product that oil leaking pollution environment and part occur aborning, and the hydraulic jack slow motion, production efficiency is low; the clamp die mechanism of machine tool adopts the hydraulic pressure Washdown type; will leak after long-term the use has contaminated environment, hydraulic pressure to fling to be subjected to the impact of hydraulic pressure larger, and drift produces yielding easily.
Summary of the invention
The technical problem that the utility model mainly solves provide a kind of pneumatic quick cold punching machine punching mechanism, its project organization is simple and practical, increases a punch forming power by times power cylinder, the utilization at logical mechanical dead point, increase the conservation degree of punch forming power, prevent that punch die from retreating, and do not pollute.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the punching mechanism that a kind of pneumatic quick cold punching machine is provided, the punching mechanism of this pneumatic quick cold punching machine comprises the adjustment fixed bar, head rod, the second connecting rod, the 3rd connecting rod, the moving slide block seat, die set, stamping cylinder, cylinder mount pad and connecting pin, one end of described adjustment fixed bar and an end of head rod are flexibly connected by connecting pin, the other end of head rod is flexibly connected by an end of connecting pin and the second connecting rod and the 3rd connecting rod, the other end of the second connecting rod is flexibly connected by connecting pin and moving slide block seat, on the front end face of moving slide block seat die set is installed, the other end of the 3rd connecting rod is fixedly connected with the piston rod of stamping cylinder by screw thread, and stamping cylinder is installed on the cylinder mount pad by screw rod.
Preferably, described stamping cylinder is double power output cylinder.
The beneficial effects of the utility model are: the punching mechanism of a kind of pneumatic quick cold punching machine of the utility model, and its project organization is simple and practical, increases punch forming power by times power cylinder, the utilization at logical mechanical dead point, increase the conservation degree of punch forming power, prevent that punch die from retreating, and do not pollute.
