Description
Technical Field
The utility model relates to a transmission, in particular to press transmission.
Background
In the prior art, parts with processing requirements of complex precision parts such as coining, lettering and the like are produced on a plurality of oil presses, and the oil presses are limited by a plurality of factors such as low efficiency, easy oil leakage, large occupied use area and the like. The production efficiency of the common press is higher than that of an oil press, but the upper and lower grinding tools must be dead against each other during cold extrusion and coining, so that the crankshaft is easy to break.
SUMMERY OF THE UTILITY MODEL
In order to solve the defects of the prior art, the utility model aims to provide a press transmission device which can improve the forming time of metal to the maximum extent.
In order to achieve the above object, the utility model provides a press transmission includes gear wheel, connecting rod, rocker, bent axle, key, connecting rod, goes up the toggle link, lower toggle link, bulb screw rod and the slider body, the gear wheel respectively with connecting rod and rocker pass through round pin axle fixed connection, the rocker passes through the key with bent axle fixed connection, the bent axle with connecting rod fixed connection, go up toggle link fixed connection on the fuselage, connecting rod and last toggle link fixed connection, toggle link and bulb screw rod fixed connection down, bulb screw rod fixed connection be in on the slider body.
Preferably, the crankshaft and the connecting rod are fixedly connected through screws.
Preferably, the connecting rod and the upper toggle link are fixedly connected by a pin.
Preferably, the lower toggle link and the ball screw are fixedly connected by a screw.
The utility model has the advantages that the slide block can stay at about 50 degrees at the bottom dead center through the unique operating curve of the multi-point toggle rod mechanism; meanwhile, the transmission mechanism integrated with the quick return mechanism has the characteristics that the speed of the sliding block is low when the sliding block moves downwards, and the speed is high when the sliding block returns, so that the forming time of metal is prolonged to the maximum extent, the plastic deformation of the metal is facilitated, the product quality and efficiency can be improved, and the material is saved.
Drawings
Fig. 1 is a front view of the present invention;
fig. 2 is a left side view of the present invention.
Wherein,
1. a bull gear; 2. a connecting rod; 3. a rocker; 4. a crankshaft; 5. a key; 6. a connecting rod; 7. an upper toggle link; 8. a lower toggle link; 9. a ball head screw; 10. a slider body.
Detailed Description
As shown in fig. 1 and 2, the utility model provides a press transmission includes gear wheel 1, connecting rod 2, rocker 3, bent axle 4, key 5, connecting rod 6, goes up toggle link 7, lower toggle link 8, bulb screw rod 9 and the slider body 10, gear wheel 1 respectively with connecting rod 2 and rocker 3 are through round pin axle fixed connection, rocker 3 passes through key 5 with bent axle 4 fixed connection, bent axle 4 with connecting rod 6 fixed connection, go up toggle link 7 fixed connection on the fuselage, connecting rod 6 and last toggle link 7 fixed connection, lower toggle link 8 and bulb screw rod 9 fixed connection, bulb screw rod 9 fixed connection be in on the slider body 10.
Preferably, the crankshaft 4 and the connecting rod 6 are fixedly connected by screws.
Preferably, the connecting rod 6 and the upper toggle link 7 are fixedly connected by a pin.
Preferably, the lower toggle link 8 and the ball screw 9 are fixedly connected by screws.
The working principle of the utility model is as follows: the power source drives a big gear 1 through gear movement to enable the big gear to rotate, the big gear 1 drives a connecting rod 2 and a rocker 3 to rotate through a pin, the rocker 3 drives a crankshaft 4 to rotate through a key 5, the crankshaft 4 drives a connecting rod 6 to rotate up and down back and forth through screw linkage, an upper toggle rod 7 is fixed on a machine body through a pin shaft to enable the upper toggle rod 7 to swing up and down, the connecting rod 6 and the upper toggle rod 7 are connected in series through a pin shaft to drive a lower toggle rod 8 to move, the lower toggle rod 8 is connected with a ball screw 9 through a screw to enable the ball screw 9 to swing up and down back, and the ball screw 9 is fixed on a sliding block body 10 through other parts to enable the sliding block to move up and down. When the slide block runs to the position before the bottom dead center, the crankshaft continues to rotate, and the slide block basically stays at the bottom dead center, so that the function of staying at the bottom dead center for 50 degrees is realized. When the crankshaft continues to rotate, the slide block starts to return, and the speed of the return is faster than that of the downward movement.
The utility model has the advantages as follows: the slide block can stay at about 50 degrees at the bottom dead center through the unique operating curve of the multi-point toggle rod mechanism; meanwhile, the transmission mechanism integrated with the quick return mechanism has the characteristics that the speed of the sliding block is low when the sliding block moves downwards, and the speed is high when the sliding block returns, so that the forming time of metal is prolonged to the maximum extent, the plastic deformation of the metal is facilitated, the product quality and efficiency can be improved, and the material is saved.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and changes will readily occur to those skilled in the art based upon the teachings of the present invention. Therefore, the technical solutions that can be obtained by logic analysis, reasoning or limited experiments based on the prior art according to the design concept of the present invention should be within the scope of the present invention and/or the protection scope defined by the claims.
