Abstract
The utility model relates to a transmitting mechanism for powder formation press. A transmission mechanism is provided with a speed reducer and an electronic clutch, so the transmitting mechanism for powder formation press can be released automatically under emergency and the operation is safer. No worm gear and worm transmission is need, and difficult normal engagement can not occurs, so the transmitting mechanism for powder formation press can guarantee normal transmission. A spindle only need to drive a cam to rotate in order to realize the processing technology of feeding, pressing, molding and stripping, so the requirement of the material and the accuracy of the spindle is low. The transmitting mechanism for powder formation press comprises a motor and a spindle. The transmitting mechanism for powder formation press is characterized in that the motor is connected with the speed reducer through the clutch; the speed reducer is connected with the spindle through a coupling joint. The spindle is orderly sleeved with an eccentric wheel, a feeding cam, a stripping cam and a molding cam.
Description
(1) technical field
The utility model relates to machinery, is specially the driving mechanism of powder forming press.
(2) background technique
Existing powder forming press mainly adopts the worm and gear transmission, its structure as shown in Figure 1, driving big flywheel 5 by motor 6 by belt pulley rotates, big flywheel 5 drives worm screw 4, worm gear 3, worm gear 3 connects eccentric shaft 2, drive bottom end rail 1 knee-action when eccentric shaft 2 do actions, the other end of eccentric shaft 2 drives feeding cam 7,8 actions of demoulding cam, makes powder through feeding, compression moulding, the demoulding.This driving mechanism has three shortcomings: one is exactly that motor does not have speed reducer, has only the semidiameter by belt pulley and big flywheel to come control rate, can not stop immediately when breaking down, dangerous; Another shortcoming is exactly that big flywheel directly drives worm screw, so the moment of flexure that worm screw is born is bigger, makes the normal engaged of worm and worm wheel be difficult to guarantee, has influence on normal transmission; The 3rd shortcoming is exactly that eccentric shaft is connected with worm gear and drives the bottom end rail action again, and be therefore bigger to the moment of torsion of eccentric shaft, higher to the material and the required precision of eccentric shaft like this.
(3) summary of the invention
At the driving mechanism of existing powder forming press, it does not have speed reducer, and urgency main shaft and motor can not be thrown off immediately; The moment of flexure that worm screw is born is bigger, makes the normal engaged of worm and worm wheel be difficult to guarantee, thereby has influence on normal transmission; Eccentric shaft is connected with worm gear and drives bottom end rail action again, the moment of torsion that eccentric shaft bore is bigger, material and the higher shortcoming of required precision to eccentric shaft, the utility model provides the driving mechanism of another powder forming press, running into urgency can throw off automatically, safer, and can guarantee normal transmission, general to the material and the required precision of eccentric shaft.
The technical solution of the utility model is such: it comprises motor, main shaft, it is characterized in that described motor connects speed reducer by clutch, described speed reducer connects main shaft by coupling, is set with eccentric wheel, feeding cam, demoulding cam and shaping cam on the described main shaft successively.
It is further characterized in that the longitudinal section of described feeding cam is fan-shaped, and described fan-shaped bottom is a rippled edge, and the centre of described rippled edge is a trough, and the crest of described trough both sides is connected with circular arc with the semicircle on described fan-shaped top; The two ends of the profile line of described demoulding cam, its longitudinal section of shaping cam are respectively circular arc, and described two circular arc radius corresponding do not wait, and the connecting line between two circular arcs is a straight line.
The utility model is applied to the powder forming press, motor drives clutch by vee-pulley, and clutch drives speed reducer by sprocket wheel, and speed reducer connects main shaft by coupling, drive camming movement when main shaft rotates, thereby realize the processing technology of feeding, compression moulding, the demoulding.This driving mechanism can be thrown off so run into urgency automatically owing to be furnished with speed reducer and electric clutch, and is safer; Owing to need use the turbine and worm transmission, there is not the situation that is difficult to normal engaged, so normal transmission can guarantee, and main shaft only need drive cam rotation and just can realize above-mentioned processing technology, so also do not need too high to the material and the required precision of main shaft.
(4) description of drawings
Fig. 1 is the schematic representation of the driving mechanism of existing powder forming press;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the plan view of feeding cam of the present utility model;
Fig. 4 is the plan view of demoulding cam of the present utility model.
(5) embodiment
See Fig. 2, the utility model comprises motor 9, main shaft 5, and motor 9 connects speed reducer 7 by clutch 8, and speed reducer 7 connects main shaft 5 by coupling 6, is set with eccentric wheel 4, feeding cam 3, demoulding cam 2 and shaping cam 1 on the main shaft 5 successively.See Fig. 3, the longitudinal section of feeding cam 3 is fan-shaped, and fan-shaped bottom is a rippled edge, and the centre of rippled edge is a trough, and the crest of trough both sides is connected with circular arc with the semicircle on fan-shaped top.The two ends of the profile line of the longitudinal section of demoulding cam 2, shaping cam 1 are respectively circular arc, two circular arc radius corresponding do not wait, connecting line between two circular arcs is a straight line, and the appearance similar of demoulding cam 2, shaping cam 1 has only been expressed the plan view of demoulding cam 2 among Fig. 4.Eccentric wheel 4, feeding cam 3, demoulding cam 2 and shaping cam 1 are decided according to concrete operative workpiece with the mounting point relation of main shaft 5.
Claims (3)
