Abstract
The invention discloses a lifting mechanism, which consists of a cam, a transition swing frame, a lifting swing frame, a return spring and an ejector rod, wherein the cam, the transition swing frame and the lifting swing frame are arranged in a rack through a rotating shaft respectively; the lifting swing frame is formed by connecting a first right-angled arm and a second right-angled arm; the transition swing frame is arranged on the lower side of the first right-angled arm; the cam is arranged on the lower side of one end of the transition swing frame; the first right-angled arm is provided with a slide block and a screw, the screw is connected with the first right-angled arm and the slide block through threads, and the lower end of the slide block is contacted with the upper side of the transition swing frame; the return spring is arranged between the second right-angled arm and the rack; and the ejector rod is arranged in a hole on the rack, and one end of the ejector rod is contacted with the outer side of the upper end of the second right-angled arm. The rotation of the cam is converted into linear motion of the ejector rod through the lifting swing frame so as to realize lifting of the ejector rod; the mechanism is simple and efficient to adjust, has large adjustable range, stable operation and low noise; and the maximum stroke length of the ejector rod can be 270 millimeters.
Description
Technical field:
The present invention relates to mechanical field, relate in particular to cold-formed machine, particularly a kind of material jacking mechanism.
Background technology:
At cold-formed machine,,, need automatic feed mechanism usually in order to improve automation degree of equipment such as processing component of rod category on the cold headers.In the material jacking mechanism of prior art, bigger gap is arranged between the movement parts, tend in the course of work produce bigger noise, and the material jacking mechanism stroke is less, be not suitable for the big component of rod category of processing length.
Summary of the invention:
The object of the present invention is to provide a kind of material jacking mechanism, described this material jacking mechanism will solve the technical problem that noise was big, stroke is little when material jacking mechanism was worked in the prior art.
This material jacking mechanism of the present invention, by cam, the transition rocker, the liftout rocker, back-moving spring and push rod constitute, described cam, transition rocker and liftout rocker are arranged in the frame by rotating shaft separately, wherein, described liftout rocker is connected and composed by one first right angle arm and one second right angle arm, described transition rocker is arranged on the downside of described first right angle arm, described cam is arranged on the downside of transition rocker one end, first right angle arm is provided with a slide block and a screw rod, described screw rod is connected with described slide block with first right angle arm by screw thread, the last side contacts of the lower end of slide block and transition rocker, described back-moving spring is arranged between described second right angle arm and the frame, described push rod is arranged in the hole on the frame, side contacts outside an end of push rod and the upper end of second right angle arm.
Further, described push rod is arranged in the slip cap, and described slip cap is arranged in the hole on the frame.
Further, the lower end of described slide block is provided with a roller.
Further, first right angle arm is provided with chute, and described slide block is arranged in the described chute.
Further, described back-moving spring is an air spring.
Further, the upper side of described transition rocker and downside are provided with the engineering plastics plate.
Operation principle of the present invention is: cam is rotated counterclockwise, and drives the transition rocker and is rotated counterclockwise equally.The transition rocker then promotes the liftout rocker by jacking block and turns clockwise, thereby promotes the push rod moving linearly.When resetting, cam and transition rocker turn clockwise, and the liftout rocker can reset under the effect of air spring.During adjustment, only need unclamp the pressing plate on the jacking block, rotary screw is adjusted the jacking block position, just can regulate the movement travel of push rod.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention is provided with cam mechanism in material jacking mechanism, the rotation of cam is converted to the rectilinear motion of push rod by the liftout rocker, realize the push rod liftout, this institutional adjustment is simple efficiently, adjustable extent is big, stable, noise is little, the maximum length of stroke of push rod can improve the value of cold working equipment greatly to 270mm.
Description of drawings:
Fig. 1 is the structural representation of material jacking mechanism of the present invention.

Further, described push rod 5 is arranged in the slip cap 51, and described slip cap 51 is arranged in the hole on the frame.
Further, the lower end of described slide block 6 is provided with a roller 61.
Further, first right angle arm is provided with chute, and described slide block 6 is arranged in the described chute.The upper end of described slide block 6 is provided with pressing plate 62 by screw.
Further, described back-moving spring 4 is air springs.
Further, the upper side of described transition rocker 2 and downside are provided with the engineering plastics plate.
