The connecting rod thrust unit
Technical field
The present invention relates to ring rolling spare production technical field, be meant especially a kind of in ring rolling spare base process employed connecting rod thrust unit.
Background technology
The application at home and abroad of ring rolling spare is very extensive, and market demand is very big, is mainly used in emerging fields such as wind-powered electricity generation, nuclear power, machinery, automobile, shipbuilding, chemical industry, military, foreign trade and space flight and aviation.
But in traditional ring rolling production technology, the process of blank being served Ring Rolling Machine is to be accomplished by manually-operated reclaimer always.So on the one hand the operator is required to be unfavorable for the automation of ring rolling process on the other hand than higher.On the production line that has used automatic conveyer; Common also is to utilize the upper punch swing of forging press and artificial assisting to push blank to conveyer from following chopping block; This just makes transport process have unstability, even can influence the service life and the precision of upper punch mould.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of ability stability and high efficiency ground the ring rolling blank to be pushed to the connecting rod thrust unit of automatic conveyer from following chopping block.
For addressing the above problem, the technical scheme that the present invention adopts is: the connecting rod thrust unit comprises: rear column, hydraulic cylinder, front column and cursor; Said cursor is included as the master arm and the slave arm of integrative-structure; The brachium of master arm is less than the brachium of slave arm, and the end of slave arm is provided with distance rod, and the junction of master arm and slave arm is movably arranged on the top of front column; The cylinder body and the rear column of said hydraulic cylinder are hinged, and the piston rod of hydraulic cylinder and the end of master arm are hinged.
The end of said slave arm is provided with several slave arm pin-and-holes, and said distance rod is provided with a distance rod pin-and-hole, is provided with pin in the distance rod pin-and-hole.
The junction of said master arm and slave arm is provided with through hole, and the top of said front column is provided with sleeve column, and sleeve column is located in the through hole and the top of sleeve column is provided with threaded column, and threaded column is provided with nut.
The top of said rear column is provided with the back draw-in groove, is provided with the back steady pin in the back draw-in groove, and the rear end of the cylinder block of hydraulic cylinder is arranged in the draw-in groove of back and through the back steady pin and connects.
The end of said master arm is provided with front bayonet slot, is provided with preceding steady pin in the front bayonet slot, and the piston rod front end of hydraulic cylinder is arranged in the front bayonet slot and through preceding steady pin and connects.
The invention has the beneficial effects as follows: above-mentioned connecting rod thrust unit, it is simple in structure, with low cost, easy to use.It can stability and high efficiency push blank to conveyer from chopping block down, not only help the lifting of automaticity, and avoided using plunger chip die to promote mould damage and the manually-operated unstability of being brought.

The specific embodiment
Through specific embodiment connecting rod thrust unit of the present invention is done further to describe in detail below.
As shown in Figure 1, the connecting rod thrust unit comprises: rear column 1, hydraulic cylinder 2, front column 3 and cursor 4; Said cursor 4 is included as the master arm 41 and slave arm 42 of integrative-structure, and the brachium of master arm 41 is less than the brachium of slave arm 42, and can have certain angle between master arm 41 and the slave arm 42; The end of slave arm 42 is provided with distance rod 5; Like Fig. 6, shown in Figure 7, the end of slave arm 42 is provided with several slave arm pin-and-holes 421, is three slave arm pin-and-holes 421 in the present embodiment; Said distance rod 5 is provided with a distance rod pin-and-hole 51; Be provided with pin 6 in the distance rod pin-and-hole 51, thereby can adjust the length of distance rod 5 through slave arm pin-and-hole 421 and cooperating of distance rod pin-and-hole 51, the junction of master arm 41 and slave arm 42 is movably arranged on the top of front column 3; The cylinder body of said hydraulic cylinder 2 and rear column 1 are hinged, and the end of the piston rod of hydraulic cylinder 2 and master arm 41 is hinged.
As preferred version; As shown in Figure 5; Said master arm 41 is provided with through hole 43 with the junction of slave arm 42, and as shown in Figure 4, the top of said front column 3 is provided with sleeve column 31; Sleeve column 31 is located in the through hole 43 and the top of sleeve column 31 is provided with threaded column 32, and threaded column 32 is provided with nut 33.
As preferred version, as shown in Figure 3, the top of said rear column 1 is provided with back draw-in groove 11, is provided with back steady pin 12 in the back draw-in groove 11, and the rear end of the cylinder block of hydraulic cylinder 2 is arranged in the draw-in groove 11 of back and through back steady pin 12 and connects.
As preferred version, like Fig. 5, shown in Figure 6, the end of said master arm 41 is provided with front bayonet slot 411, and steady pin 412 before being provided with in the front bayonet slot 411, the piston rod front end of hydraulic cylinder 2 are arranged in the front bayonet slot 411 and through preceding steady pin 412 and connect.
Operation principle of the present invention is: above-mentioned connecting rod thrust unit needs choose reasonable and relates to the stroke of hydraulic cylinder 2 before use, and the relative position of cursor 4 geomeries and front column 3 and rear column 1 adapts the layout on itself and the production line.As shown in Figure 2, during use, the piston rod of hydraulic cylinder 2 stretches out, and promotion master arm 41 and slave arm 42 are the center rotation with the top of front column 3, thereby make distance rod 5 move, and realize the promotion to the ring rolling blank.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
