Abstract
Disclosed is an ejection mechanism for cold forming machine stamping die, which is composed of a main connecting rod, a main slider, a connecting rod link pin, a small connecting rod, a connecting rod link pin, a pin , a stamping die swing frame, a protection cover, an insurance gas cover, a safety bolt, a lock nut, a regulating screw barrel, a stamping die injection cam, a roller, a regulating bolt, a lock nut, a swing-bar shaft, a mandril, a small shaft, a swing bar, a rolling wheel shaft and a main connecting rod shaft, the main connecting rod shaft is used as the circle center fulcrum of the main connecting rod which is connected with the main connecting rod shaft, the main connecting rod is connected with the small connecting rod which is connected with the stamping die swing frame, and the stamping die swing frame is connected with the pin used as the circle center fulcrum of the stamping die swing frame, the stamping die injection cam and the roller are both disposed on the stamping die swing frame which is connected with the swing bar disposed on the swing bar shaft, the swing bar is connected with the mandril. The ejection length and ejection time of a plurality of working positions can be respectively and freely adjusted by using the main connecting rod and the small connecting rod to drive the stamping swing frame, a plurality of parts with comparatively complicated shape structures can be processed, and the ejection safety device of every working position is respectively independent.
Description
Technical field
The utility model relates to mechanical field, relates in particular to metal cold working equipment, particularly a kind of cold shaping machine punch die ejecting mechanism.
Background technology
In the prior art, in the punch die ejecting mechanism of cold shaping machine, several operating positions eject length and ejection cycle free adjustment separately, part that therefore can not machining shape structure more complicated, and several operating positions eject shared safeties, have potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of cold shaping machine punch die ejecting mechanism, and what described this cold shaping machine punch die ejecting mechanism will solve in the prior art several operating positions in the cold shaping machine punch die ejecting mechanism ejects length and the ejection cycle technical problem of free adjustment, shared safeties separately.
This cold shaping machine punch die ejecting mechanism of the present utility model is by master connecting-rod, master slider, pitman pin, small rod, pitman pin, bearing pin, the punch die rocker, protective cover, insurance gas lid, safety bolt, locking nut, Adjusting bolt Adjusting screw, punch die ejects cam, roller, regulate bolt, locking nut, the fork axle, push rod, little axle, fork, roller shaft and master connecting-rod axle constitute, wherein, described master connecting-rod is center of circle fulcrum with the master connecting-rod axle and is connected with it, master connecting-rod is connected with small rod, small rod is connected with the punch die rocker, the punch die rocker is connected with bearing pin and is center of circle fulcrum with the bearing pin, described punch die ejects cam and roller all is arranged on the punch die rocker, the punch die rocker is connected with described fork, fork is arranged on the fork axle, and fork is connected with described push rod.
Operation principle of the present utility model is: master connecting-rod is to be delivered to the punch die rocker through the traction small rod after center of circle fulcrum swings up and down with the master connecting-rod axle, the punch die rocker is swung for center of circle fulcrum with the bearing pin, eject the transmission of power of cam and roller by being contained in punch die on the punch die rocker, making fork make center of circle fulcrum with the fork axle swings, the swing of fork axle, convert horizontal power to by push rod, this power can eject from punch die being produced workpiece in process of production, finishes the action that whole punch die ejects.
The utility model and prior art compare, and its effect is actively with tangible.Punch die is ejected cam to the utility model and roller is arranged on the punch die rocker, utilize master connecting-rod, small rod to drive the punch die rocker, several operating positions eject length and ejection cycle free adjustment separately, part that can machining shape structure more complicated, and each operating position to eject safeties independent separately.Eliminate safe hidden trouble.
