Specific embodiment
Present invention will be further explained below with reference to the attached drawings and specific embodiments.
The present invention provides one kind three and interlocks cold rolling head molding machine, its working principle is that, firstly, as shown in Figure 1, charge bar 8
It is laterally put into three feed hoppers 5, successively falls into respective channel 3 in mould bases 1 by respective buffer channel 17 and feed inlet 4 and keep right
In position, the first cylinder 10 driving movable block 9 is moved to the left and charge bar 8 is driven to be moved to the left, as shown in Fig. 2, in the present embodiment,
First elastic component 7, the second elastic component 11 and the first cylinder 10 correspond respectively, during movable block 9 moves to left, due to the first bullet
Property part 7 be uniformly distributed along 8 stick body direction of charge bar, the first cylinder 10 and the second elastic component 11 complete the push to charge bar 8 jointly,
Until the curved surface of movable block 9 and the curved surface of 3 left side of channel just wrap the entire periphery wall of the charge bar 8, three lead at this time
The second elastic component 11 on the first elastic component 7 and movable block 9 of the respective left end in road 3 is respectively held against the 8 stick body two sides of charge bar and is in
Compressive state, and planar section shelters from 4 lower section of feed inlet respectively on movable block 9, to prevent the charge bar 8 in buffer channel 17
It is stuck in the reciprocating movement that movable block 9 is interfered in the channel 3 of plane on movable block 9；Secondly, the second cylinder 13 in punching mechanism 2
Driving formed punch 12 is moved along 8 axis direction of charge bar towards charge bar 8, and 8 one end of charge bar contacted with formed punch 12 is squeezed deformation, charge bar
In gap in 8 fillings to formed punch 12 between hollow cylinder 14 and solid regular hexagonal prism 15, after molding, the driving of the second cylinder 13
Formed punch 12 exits, to complete the head molding of charge bar 8, in the present embodiment, can mold hexagonal using solid regular hexagonal prism 15
Head；Finally, the first cylinder 10 driving movable block 9 moves right, the first elastic component 7 and the second elastic component 11 stretch in opposite directions, first
Elastic component 7 stretch generate elastic force pushes and pass through air inlet 16 air blowing keep head molded charge bar 8 fall into discharge port 6, when
Molded 8 bullet of charge bar in head is not fallen into discharge port smoothly to 9 curved end of movable block due to elastic force is excessive by the first elastic component 7
When 6, the second elastic component 11 for being now placed in 9 curved end of movable block can then generate elastic force charge bar that head is molded respectively
8 again bullet and then fall into discharge port 6 to each 3 left end of channel, so far complete the entire head shaping work of charge bar 8.
Preferred embodiments of the present invention are described above, but are not to be construed as limiting the scope of the invention.This hair
Bright to be not only limited to above embodiments, specific structure is allowed to vary, such as the end face and buffer channel in movable block 9 and channel 3
17 correspondingly change according to the shape of charge bar 8；According to the replaceable formed punch 12 of different shapes of 8 head forming shape of charge bar；
Tiltable certain angle under the premise of not influencing blanking of buffer channel 17；Movable block 9 may be provided in 3 other side of channel, correspondingly, into
Material mouth 4 and discharge port 6 can also carry out the exchange of left-right position, all made various in the protection scope of demand for independence of the present invention
Variation is within the scope of the invention.
