Abstract
The utility model discloses a support material device of a cold header. The support material device of the cold header comprises a flexible base, a transmission shaft, and an ejector pin. A flexible shaft is provided with a support material cam which rotates around the flexible shaft. A roller is arranged on and connected with the flexible base through a shaft, and the roller is matched with the support material cam. Two ends of the flexible base are respectively connected with a connecting rod and a support in a hinged mode. The connecting rod is connected with a rocker in a hinged mode. The ejector pin is fixed on the rocker. The support is hinged with the center portion of the rocker. A spring support is arranged on the support. A return spring is arranged between the spring support and the flexible base. According to the support material device of the cold header, with the rotary motion of the support material cam and the function of the spring, the roller arranged on the flexible base is capable of sticking to a curve surface of the support material cam. The flexible base drives the rocker to swing from left to right through the connecting rod, and therefore the function of support materials is achieved. The support material device of the cold header has the advantages of being simple in integrity structure, convenient to operate, and high in work efficiency.
Description
Technical field
The utility model relates to the Lifting Device of a kind of cold headers, particularly cold headers.
Background technology
Cold headers are at room temperature the equipment of the forging and molding of the top overstriking of bar or wire rod, and cold headers are mainly for the manufacture of parts such as bolt, screws.Method by adopting cold-heading is with bolt, the head upsetting of screw goes out, then can as far as possible fewly cut or not cut, and then be directly formed to the shape and size that people want, not only save lot of materials, and increase substantially production efficiency, significantly improve the mechanical strength that upsetting goes out part, therefore in each step work of cold headers, all be important link, but all occur in the Lifting Device of present cold headers when punching press, when being added to thimble owing to the huge impulse force that conducts, very easily cause the thimble fracture, cause simultaneously die assembly to damage, cause unnecessary loss, so efficient is low, cost is high, and complex structure.
The utility model content
The purpose of this utility model be provide in order to solve above-mentioned the deficiencies in the prior art a kind of simple in structure, easy to operate, cost is low and the Lifting Device of the cold headers of high efficiency.
To achieve these goals, the Lifting Device of the cold headers that the utility model is designed, comprise sliding seat, power transmission shaft and thimble, be provided with the liftout cam that moves around axle at movable axis, on sliding seat, be connected with roller by axle, and roller cooperates with the liftout cam, the sliding seat two ends are hinged with respectively connecting rod and support, be hinged with rocking arm at connecting rod, thimble is fixed on the rocking arm; center and the support of rocking arm are hinged, are provided with spring(-supported) mount at support, are provided with back-moving spring between spring(-supported) mount and the sliding seat.
The Lifting Device of the cold headers that the utility model obtains, be rotated motion by the liftout cam, effect by spring, so that the cam on the sliding seat is close on the curved surface of liftout cam, then sliding seat is vacillated now to the left, now to the right by connecting rod drive rocking arm, thereby realize the effect of liftout, so that overall structure is simple, easy to operate, cost is low and high efficiency.
Description of drawings
Fig. 1 is the structural representation of present embodiment;
Among the figure: sliding seat 1, power transmission shaft 2, thimble 3, liftout cam 4, roller 5, connecting rod 6, support 7, rocking arm 8, spring(-supported) mount 9, back-moving spring 10.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment 1:
As shown in Figure 1, the Lifting Device of the cold headers that the utility model provides, comprise sliding seat 1, power transmission shaft 2 and thimble 3, be provided with the liftout cam 4 that moves around axle at movable axis 2, on sliding seat 1, be connected with roller 5 by axle, and roller 5 cooperates with liftout cam 4, sliding seat 1 two ends are hinged with respectively connecting rod 6 and support 7, be hinged with rocking arm 8 at connecting rod 6, thimble 3 is fixed on the rocking arm 8; center of rocking arm 8 and support 7 are hinged, are provided with spring(-supported) mount 9 at support 7, is provided with back-moving spring 10 between spring(-supported) mount 9 and the sliding seat 1.
State during work: by power transmission shaft 2 runnings, thereby so that liftout cam 4 runnings on the power transmission shaft 2, this moment is because under the effect of back-moving spring 10, so that the roller 5 on the sliding seat 1 is close on the liftout cam 4, this moment is because the running of liftout cam 4, when the convex surface of liftout cam 4 when beginning to touch roller 5, so that give gravity in top of roller 5, so that sliding seat 1 on measure existing inclination, this moment, connecting rod 6 was tilted to the left, drive simultaneously rocking arm 8, so that rocking arm 8 waves, thereby guarantee that thimble 3 withstands item to the right; When the convex surface of liftout cam 4 touches the below of roller 5, so that the below of roller 5 obtains a gravity, so that the inclination of the below of sliding seat 1, thereby drivening rod 6 turns round to the right, drives rocking arms 8 belows by connecting rod 6 and shakes left, so that thimble 3 leaves item.
