Invention effect and effect
According to cold extrusion device of the present invention, owing to present invention employs a point face unit, therefore can effectively make the head of nut base upward, afterbody, saves manpower down, improves efficiency.
Owing to present invention employs the transmission road of two arcs, namely second transmit road and the 3rd and transmit road, make nut base all can with head upward, afterbody direction down enters cold-stamped step, improves efficiency.Simultaneously owing to have employed two transmission roads and two air-legs, the setting of its relative position effectively can reduce the vibration being caused the position supplying nut base to manipulator by point vibration of face unit, make the supply of nut base more stable, manipulator gripping nut base is more stable.In addition, air-leg and transmit road be arranged so that the speed of supplying nut base can according to the gripping rate adaptation of manipulator.
Detailed description of the invention
The detailed description of the invention of cold extrusion device of the present invention is described below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram of the embodiment of cold extrusion device of the present invention.As shown in Figure 1, cold extrusion device 10 comprises: point face unit 2, first transmits road 3, second and transmits road 4, the 3rd transmission road 5, first air-leg 6, second air-leg 7, receiving slit 9 and manipulator 8.
Point face unit 2 comprises main cylinder 21, spiral slide 23 and vibrating motor 24.Spiral slide rises along the spiral inner wall of main cylinder 21, and the bottom that vibrating motor is positioned at main cylinder vibrates for making whole point of face unit 2.
Fig. 2 is the partial enlarged drawing of the embodiment split unit of cold extrusion device of the present invention, and Fig. 3 is the side view of the embodiment split unit of cold extrusion device of the present invention.As shown in Figure 1, 2, 3, when vibrating motor 24 drives whole point of face unit 2 to vibrate, nut base 22 moves upward along spiral slide 23 owing to being subject to the effect of centrifugal force.There is between the end of spiral slide 23 and the sidewall of main cylinder one section of strip crevice, the width in this gap is greater than the diameter of the afterbody 222 of nut base 22, be less than the diameter of the head 221 of nut base 22, therefore when nut base 22 moves upward to strip crevice 25 place along spiral slide 23, some nut bases 22 are fallen in strip crevice 25 due to afterbody, thus formed head upper afterbody under arrangement.And because whole point of face unit is all in vibration, the afterbody 222 therefore facilitating nut base 22 is fallen in gap.And those afterbodys nut embryo base 22 could not fallen in strip crevice 25 can continue to run forward along spiral slide 23, finally again fall in main cylinder and enter next round screening.As shown in Figure 3, first transmits road 3 also has upper cover 31, prevents from making nut base 22 drop due to vibration.
The end and first of strip crevice 25 transmits road 3 and is connected, first cross section of transmitting road 3 is rectangle, and the first bottom surface of transmitting road 3 has the gap consistent with the width of strip crevice, nut base 22 behind undue face unit 2 points of faces is run to by strip crevice 25 on first transmission road 3, because the first transmission road 3 has gap equally, therefore nut base 22 still keeps head 221 upper, afterbody 222 under state.First transmission road 3 is downward-sloping, and therefore nut base 22 can move downward along the first transmission road because the effect of gravity is easier.
First end transmitting road 3 has the first downward outlet 31 transmitting outlet 31, the first transmission road in road and is connected with the be positioned at the second transmission road 4 second entrance 41 transmitting road.When nut base 22 moves to outlet 31 place in the first transmission road, the outlet 31 that can transmit road by first enters the second transmission road through the entrance 41 that second transmits road.Second transmission road is reclinate arc, move downward because the effect of gravity transmits road 4 along second the outlet 42 that second transmits road after nut base 22 enters the second transmission road 4, and enter in receiving slit 9 by the second outlet 42 transmitting road, now, the head 221 of nut base 22 transmits the outlet 42 in road facing to second.The first air-leg 6 being now positioned at receiving slit 9 side can be pushed to before the second air-leg 7 by parallel for nut base 22 by the side of nut base 22, now the head 221 of nut base 22 transmits the entrance 51 in road facing to the 3rd, afterbody 222 is facing to the second air-leg 7, and nut base 22 pushes in the 3rd transmission road 5 by the second air-leg 7 afterwards.3rd distal opening transmitting road 5 is the 3rd outlet 52 transmitting road, when being full of nut base 22 in the 3rd transmission road 5, the entrance 51 that second air-leg 7 often transmits road by the 3rd pushes a nut base 22, all have a nut base 22 to be sent by the outlet 52 that the 3rd transmits road, the 3rd length transmitting road 5 just keeps allowing the head of a nut base 22 expose but the outlet 52 that can not transmit road from the 3rd is dropped.
When nut base 22 head 221 by the 3rd transmit the outlet 52 in road expose time, manipulator 8 can from here by nut base 22 gripping, and be positioned over carry out in cold rolling hole cold rolling.
3rd shape transmitting road 5 is the last period is parallel to the ground, the passage of one section of arc below, distal opening and horizontal plane, the effect of this shape is when being full of nut base 22 in passage, due to the effect of frictional force, make nut embryo can not return back to the entrance 51 in the 3rd transmission road due to Action of Gravity Field.
The driving velocity of the first air-leg 6 and the second air-leg 7 and the speed of manipulator 8 gripping nut base 22 are consistent.
Fig. 4 is the schematic diagram of cold extrusion unit in the embodiment of cold extrusion device of the present invention.As shown in Figure 4, cold extrusion unit 11 has cold-extruded splenium 12 and manipulator 8, after nut base 22 is transmitted outlet 52 gripping in road by the 3rd by manipulator 8, manipulator 8 can move to up and down between two parts of the cold-extruded splenium 12 of cold extrusion unit 11, the top of cold-extruded splenium has pressure column, bottom has mould, and the head 221 of nut base 22 is squeezed into disc by cold-extruded splenium.
Embodiment effect and effect
According to embodiments of the invention, road and the 3rd transmission road is transmitted on the one hand because the present embodiment have employed the first transmission road, second, and the second transmission road and the 3rd transmits road and is arc, and two arcs be arranged in parallel, therefore can ensure that nut base finally upwards transmits the outlet in road from the 3rd with head 221 and expose.On the other hand, because point face device is in continuous vibration, the mode therefore adopting multistage to transmit road transport can reduce the vibration at final outlet place, makes the supply of nut base more steady.
In addition, owing to have employed two air-legs, therefore better can control the supply rate of nut base, make it better match with the grasp speed of manipulator.
In addition, because the 3rd height of opening transmitting road matches with the height of manipulator, therefore manipulator only need move horizontally and the gripping of nut base can be processed in cold extrusion unit, has therefore simplified the action of manipulator, has improve efficiency.
