The specific embodiment
The specific embodiment of cold extrusion device of the present utility model is described below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram of the embodiment of the utility model cold extrusion device.As shown in Figure 1, cold extrusion device 10 comprises: minute face unit 2, first transmits road 3, second and transmits road 4, the 3rd transmission road 5, the first air-leg 6, the second air-leg 7, receiving slit 9 and manipulator 8.
Fig. 2 is the partial enlarged drawing of the embodiment split unit of the utility model cold extrusion device, and Fig. 3 is the side view of the embodiment split unit of the utility model cold extrusion device.As shown in Figure 1, 2, 3, when vibrating motor 24 drives face unit 2 vibration in whole minute, nut base 22 moves upward along spiral slide 23 owing to being subject to the effect of centrifugal force.Between the sidewall of the end of spiral slide 23 and nut bearing tube 21, there is 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 because afterbody is fallen in strip crevice 25, thus form head upper afterbody under arrangement.And because whole minute face unit is all in vibration, therefore promoted the afterbody 222 of nut base 22 to fall in gap.And those afterbodys could not be fallen into nut base in strip crevice 25 22 and can continue move forward along spiral slide 23, finally again fall into and in nut bearing tube 21, enter next round and screen.As shown in Figure 3, first transmits road 3 also has upper cover 31, prevents from dropping because vibration makes nut base 22.
The end of strip crevice 25 and first transmits road 3 and is connected, the 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 after the 2 minutes faces in undue face unit is run on the first transmission road 3 by strip crevice 25, because the first transmission road 3 has gap equally, therefore nut base 22 still keeps head 221 upper, afterbody 222 under state.The first transmission road 3 is downward-sloping, so nut base 22 can more easily move downward along the first transmission road due to the effect of gravity.
The first end that transmits road 3 has the first downward outlet 31 that transmits outlet 31, the first transmission roads in road and is connected with the second entrance 41 that transmits road that is positioned at the second transmission road 4.When nut base 22 moves to outlet 31 place in the first transmission road, can through the entrance 41 in the second transmission road, enter the second transmission road by the outlet 31 in the first transmission road.The second transmission road is reclinate arc, effect due to gravity after nut base 22 enters the second transmission road 4 moves downward the outlet 42 in the second transmission road along the second transmission road 4, and entered in receiving slit 9 by the outlet 42 in the second transmission road, now, the head 221 of nut base 22 is facing to the second outlet 42 that transmits road.Now be positioned at receiving slit 9 sides the first air-leg 6 can by the side of nut base 22 by nut base 22 parallel be pushed to the second air-leg 7 before, now the head 221 of nut base 22 is facing to the entrance 51 in the 3rd transmission road, afterbody 222 is facing to the second air-leg 7, and the second air-leg 7 pushes nut base 22 in the 3rd transmission road 5 afterwards.The 3rd end openings that transmits road 5 is the outlet 52 in the 3rd transmission road, while being full of nut base 22 in the 3rd transmission road 5, the second air-leg 7 often pushes a nut base 22 by the 3rd entrance 51 that transmits road, all have a nut base 22 and sent by the 3rd outlet 52 that transmits road, the 3rd length that transmits road 5 just keeps allowing the head of a nut base 22 expose but can not drop from the 3rd outlet 52 that transmits road.
When the head 221 of nut base 22 is exposed by the 3rd outlet 52 that transmits road, manipulator 8 can be from here by 22 grippings of nut base, and be positioned in cold rolling hole, carry out cold rolling.
Be the 3rd the last period that is shaped as of transmitting road 5 parallel to the ground, after be the passage of one section of arc, end openings is vertical with horizontal plane, the effect of this shape is while being full of nut base 22 in passage, due to the effect of frictional force, make nut base can not return back to due to Action of Gravity Field the entrance 51 in the 3rd transmission road.
The speed of the driving velocity of the first air-leg 6 and the second air-leg 7 and manipulator 8 gripping nut bases 22 is consistent.
Fig. 4 is the schematic diagram of cold extrusion unit in the embodiment of the utility model cold extrusion device.As shown in Figure 4, cold extrusion unit 11 has cold-extruded splenium 12 and manipulator 8, when manipulator 8 transmits nut base 22 after the outlet 52 places gripping in road by the 3rd, manipulator 8 can move to up and down between two parts of cold-extruded splenium 12 of cold extrusion unit 11, the top of cold-extruded splenium has pressure column, bottom has mould, and cold-extruded splenium is squeezed into disc by the head of nut base 22 221.
Embodiment effect and effect
According to embodiment of the present utility model, on the one hand because the present embodiment has adopted first to transmit road, the second transmission road and the 3rd transmission road, and the second transmission road and the 3rd transmits road and is arc, and two arcs be arranged in parallel, therefore can guarantee that nut base finally upwards exposes with head 221 from the outlet in the 3rd transmission road.On the other hand, because minute face device is in continuous vibration, the mode that therefore adopts multistage to transmit road transportation can reduce the vibration at final outlet place, makes the supply of nut base more steady.
In addition, owing to having adopted two air-legs, therefore can better control the supply rate of nut base, it is better matched with the grasp speed of manipulator.
In addition, because the 3rd height of opening and the height of manipulator that transmits road matches, so manipulator only need move horizontally and the gripping of nut base can be processed in cold extrusion unit, so simplified the action of manipulator, improved efficiency.
