When the induction head of the mechanical valve 6 is extruded by external force, the mechanical valve 6 is closed, and the space between the feeding mechanism 2 and an external power source is cut off, so that the feeding mechanism 2 stops feeding, and the feeding mechanism 2 automatically resets after stopping feeding. When the induction head of the mechanical valve 6 is not extruded by external force, the mechanical valve 6 is communicated with the feeding mechanism 2 and an external power source, so that the feeding mechanism 2 feeds materials.
The crank arm 7 is movably inserted on the frame 1, the free end of the crank arm extends to the outer side surface of the frame 1, the free end is provided with a first connecting rod 71 and a second connecting rod 72 which are arranged in parallel, and the first connecting rod 71 is positioned below the induction head of the mechanical valve 6. The start end of the crank arm 7 extends towards the tool holder 42 of the stamping mechanism 4, and the end of the start end has a crank portion 7a, and the crank arm 7 body, the crank portion 7a and the first connecting rod 71 are orthogonal in pairs. The die holder 42 is provided with a striking block 421 arranged along the punching direction, and the lower end of the striking block 421 is arranged opposite to the crank portion 7 a.
When the punching mechanism 4 punches along the punching direction, the striking block 421 strikes the crank portion 7a of the crank arm 7, so that the crank arm 7 rotates along the axis thereof, and the first connecting rod 71 is driven to apply pressure to the mechanical valve 6, so that the mechanical valve 6 cuts off the connection between the feeding mechanism 2 and an external power source.
The striking block 421 has a certain length, and the crank arm 7 will keep the state of pressing the mechanical valve 6 under the interference of the striking block 421 during the punching process, so as to ensure that the feeding mechanism 2 will not feed during the punching process. And when punching press mechanism 4 resets, until hitting piece 421 along with punching press mechanism 4 and separating with the crank portion 7a of crank arm 7 completely, crank arm 7 can just freely swing, can just carry out the pay-off after guaranteeing that punching press mechanism 4 vacates the feed block 3 discharge gate completely from this, avoids punching press mechanism 4 not vacating the feed block 3 discharge gate, and feed mechanism 2 just begins the pay-off and makes copper strips 9 support and press on cutter 43, and then leads to the crooked condition that can not normally pay-off of copper strips 9.
The locking block 8 is arranged on the frame 1 in a sliding manner along the feeding direction, a first spring 81 is arranged between the first end of the locking block and the side plate 11 at the feeding side of the frame 1, the second end of the locking block extends towards the second connecting rod 72, and the first end of the locking block 8 is also provided with a hook part 8a extending towards the feeding mechanism 2.
When the feeding mechanism 2 is cut off, the automatic reset is started, and the second end of the locking block 8 is simultaneously driven to be drawn out from the lower part of the second connecting rod 72, so that a space is provided for the crank arm 7 to swing.
If the feeding mechanism 2 fails to complete the reset after the punching reset of the punching mechanism 4, the lock 8 is engaged under the second link 72 by the first spring 81, so that the first link 71 maintains the state of pressing the mechanical valve 6, and the reset operation is continued until the lock 8 is pulled out from under the second link 72. Thus, feeding can be ensured when the feeding mechanism 2 is completely reset, and the consistency of the feeding length is ensured.
By the copper strip 9 forming compression mould, the problem that the copper strip 9 cannot be normally fed due to bending of the copper strip 9 caused by pressing the copper strip 9 against the cutter 43 because the feeding mechanism 2 starts feeding when the stamping mechanism 4 does not reset is effectively avoided; meanwhile, the problem that punching consistency is affected due to inconsistent feeding length caused by feeding when the feeding mechanism 2 is not completely reset is avoided. From this, guarantee that stamping mechanism 4 and feeding mechanism 2 all accomplish just pay-off under the circumstances that resets, effectively adapt to the production rhythm of punching press at a high speed, improve stamping efficiency, and guarantee the stability of the operation of copper strips 9 shaping crimping mould.

Thus, when the feed cylinder 21 pushes the clamp assembly to move toward the press mechanism 4, feeding can be performed. When the feeding cylinder 21 is cut off from the power source by the mechanical valve 6, the feeding cylinder 21 drives the clamping assembly to automatically reset.
With continued reference to fig. 7, hook portion 8a of lock block 8 extends toward connection head 211, and its side near side plate 11 is opposite to connection head 211. When the feeding cylinder 21 drives the clamping assembly to automatically reset, the connector 211 contacts with the hook portion 8a of the locking block 8, and drives the second end of the locking block 8 to be drawn out from the lower portion of the second connecting rod 72.
With continuing reference to fig. 1-2 and fig. 3-4, in this embodiment, the clamping assembly includes a first retaining device 22 and a second retaining device 23 sequentially disposed along the feeding direction, the first retaining device 22 is slidably disposed on the frame 1 and connected to the connecting joint 211; the second retaining device 23 is fixedly arranged on the frame 1.
During feeding, the feeding cylinder 21 drives the first stopping device 22 to move along the feeding direction, and the copper strip 9 and the first stopping device generate a friction force opposite to the feeding direction, so that the first stopping device 22 clamps the copper strip 9 and drives the copper strip 9 to feed.
After feeding is completed, the feeding cylinder 21 drives the first retaining device 22 to reset, the second retaining device 23 clamps the copper strip 9 under the action of the reverse tension of the copper strip 9, and the first retaining device moves in the reverse direction (the reverse direction is the same as the reverse tension of the copper strip 9) relative to the copper strip 9 along the feeding direction, so that the copper strip 9 cannot be clamped, and the first retaining device and the second retaining device reset together with the feeding cylinder 21 to perform feeding next time.
The copper strip 9 can be clamped, fed and stopped by adopting the two stopping devices, and the structure is simple and convenient to popularize and apply.
In the embodiment, the first retaining device 22 and the second retaining device 23 are the same retaining device, so that the complexity of the feeding mechanism 2 is simplified and the manufacturing cost of the feeding mechanism 2 is reduced.
Taking the first anti-backup device 22 as an example, in the present embodiment, the first anti-backup device 22 includes an L-shaped fixed block 221, a swinging block 222, a cover plate 223, a guide post 224 and a second spring 225. The horizontal part of the L-shaped fixing block 221 has a passing groove 221a arranged along the feeding direction, and the copper belt 9 passes through the passing groove 221 a. The swing block 222 is rotatably disposed at a vertical portion of the L-shaped fixing block 221 and is inclined toward one side of the feeding direction. The upper end of the swing block 222 extends into the material passing groove 221a and presses the copper strip 9 into the material passing groove 221 a.
The cover plate 223 covers the L-shaped fixing block 221 and has a protrusion 223a inserted into the material passing groove 221a, and a material passing gap is formed between the upper end surface of the protrusion 223a and the bottom of the material passing groove 221a, so as to limit the vertical deformation range of the copper strip 9 in the material passing groove 221a, so that the copper strip 9 is fed in a straight form, and the situation that the copper strip 9 cannot be normally fed due to bending in the process of pushing the copper strip 9 is avoided.
A first end of the guide post 224 traverses the lower end of the swing block 222 and is fixed to the cover plate 223 by a lock pin. The second end of the guide post 224 extends away from the lower end of the swing block 222, and the second end thereof is provided with an adjustable nut 2241. The second spring 225 is sleeved on the guide post 224, and two ends of the second spring 225 are respectively abutted between the lower end of the swing block 222 and the adjustable nut 2241. Thus, the compression amount of the second spring 225 can be changed by rotating the adjustable nut 2241, so that the acting force exerted on the swinging block 222 by the second spring 225 is adjusted, the pressure exerted on the copper strip 9 by the swinging block 222 is further changed, and the feeding resistance of the copper strip 9 is adjusted.
In addition, a movable region 223b is concavely formed on the surface of the cover plate 223 opposite to the L-shaped fixed block 221, and the swing block 222 is positioned in the movable region 223 b. Therefore, the swinging amplitude of the swinging block 222 is limited, and the situation that the swinging block 222 jumps due to overlarge swinging amplitude and cannot timely clamp the copper belt 9 is avoided.
In the present embodiment, the stamping mechanism 4 includes a housing 41 fixed to the frame 1, a tool holder 42 is slidably disposed in the housing 41 along the stamping direction, and a cutting blade 43 is disposed on the tool holder 42 and faces the forming mechanism 5. During stamping, the cutting knife 43 cuts off the copper strip 9 from the discharge side of the feeding block 3
A clamping groove (not shown) arranged along the stamping direction is arranged at one side of the cutter die holder 42 close to the rack 1, and the collision block 421 is arranged in the clamping groove. When the punching mechanism 4 punches along the punching direction, the striking block 421 strikes the crank portion 7a of the crank arm 7, so that the crank arm 7 rotates along its own axis, and the crank portion 7a is clamped between the side wall of the card slot and the side wall of the striking block 421. Thus, it is possible to avoid the situation where the crank arm 7 is rotated too much and the first link 71 violently hits the mechanical valve 6 when the striking block 421 strikes the crank portion 7a of the crank arm 7 during the high-speed punching.
In this embodiment, a sliding groove 1a is provided on the inner side surface of the frame 1, and the lock block 8 is slidably provided in the sliding groove 1 a. The sliding groove 1a can guide the sliding of the locking piece 8 and keep the stability of the sliding of the locking piece 8.
Correspondingly, an avoiding area communicated with the chute 1a is arranged on the inner side surface of the frame 1, and the second connecting rod 72 is positioned in the avoiding area. Thus, the lock block 8 can be smoothly inserted under the second link 72 and smoothly withdrawn from under the second link 72 in the rapid press process.
In this embodiment, the lock block 8 is provided with a limit block 8b, and the limit block 8b is close to the punching mechanism 4. Thereby, the movement of the locking block 8 is limited.
The above description is only a preferred embodiment of the present invention and should not be construed as limiting the present invention, and any slight modifications, equivalent substitutions and improvements made to the above embodiment in accordance with the technical spirit of the present invention should be included in the scope of the technical solution of the present invention.
