In order to illustrate the technical effect of the present invention, a general working manner of the welding apparatus for radial cold connection of a multi-strand wire body according to the present invention is described:
in the working process, as shown in fig. 3, a first region 3 of a plurality of strand bodies 2 to be welded together is placed in a groove formed by an ultrasonic welding head 1, a limiting block 4 and a first extrusion block 5, and a first horizontal power 6 is started to enable the first extrusion block 5 to move towards the limiting block 4, so that the strand bodies 2 which are originally relatively loose are properly gathered between the limiting block 4 and the first extrusion block 5, and at the moment, a loose gap still exists between the strand bodies 2.
After the above process is completed, as shown in fig. 4, the second horizontal power 8 is started, so that the second extrusion block 7 moves toward the first extrusion block 5 until abutting against the first extrusion block 5, and a closed annular space is formed among the ultrasonic welding head 1, the first extrusion block 5, the second extrusion block 7 and the limiting block 4, and is used for performing closed extrusion from the periphery of the strand bodies 2.

In summary, in the above process, the first transverse pressing causes the transverse gap between the strand bodies 2 to be pressed and adjusted, and the longitudinal pressing causes the longitudinal gap between the strand bodies 2 to be pressed and adjusted, so that the transverse gap and the longitudinal gap between the strand bodies 2 are adjusted, respectively, to obtain a relatively regular state, and finally the connection is completed by ultrasonic welding.
As a preference of the above embodiment, as shown in fig. 6, the first horizontal power 6, the second horizontal power 8 and the vertical power 9 are respectively a first cylinder, a second cylinder and a vertical cylinder including a rod chamber and a rodless chamber; wherein, the rodless cavity of the second cylinder is communicated with the rod cavity of the vertical cylinder through an external pipeline 10. The rodless cavities referred to in the present invention are all connected to the oil inlet pipeline, and the rod cavities are all connected to the oil return pipeline, which will not be described further below.
The cylinder is adopted as a power structure, so that automatic control is convenient to realize, in the preferred scheme, the second cylinder and the vertical cylinder can be linked through the external pipeline 10, so that the control difficulty is reduced, the specific control mode comprises various modes, a working process capable of realizing a better effect can be explained through a subsequent optimized implementation mode, and the operation cost of equipment is reduced on the basis of improving the welding effect.
As the optimization of the above embodiment, the bottom of the limiting block 4 is provided with the supporting spring 11, and the supporting spring 11 elastically supports the limiting block 4, so that the use of components is reduced, on one hand, the cost of the equipment is reduced, on the other hand, the number of control ends is reduced, and the control difficulty of the equipment is reduced.
As an installation mode of the vertical cylinder, a cylinder body of the vertical cylinder is fixedly arranged, and the end part of a piston rod of the vertical cylinder is in a free state; the cylinder body of the second cylinder is connected with the longitudinal guide structure, and the second extrusion block 7 is always attached to the top of the limiting block 4 before and after horizontal movement. In the above structural form, as shown in fig. 4, the limiting block 4 can always support the second extrusion block 7, the second horizontal power 8 follows up and down the second extrusion block 7 under the guidance of the longitudinal guide structure, and when the second extrusion block 7 needs to be longitudinally extruded, the vertical cylinder is started, and the end of the freely arranged piston rod directly extrudes the second extrusion block 7; the above structure forms the extrusion position of the vertical cylinder to be convenient to adjust, thereby enhancing the integral rigidity of the device.
Or, as another mode, the end part of the piston rod of the vertical cylinder is fixedly connected with the cylinder body of the second cylinder, and the top of the limiting block is always attached to the second extrusion block before and after the second extrusion block moves horizontally.
As a preference of the above embodiment, as shown in fig. 7 and 8, the first compression block 5 includes: the connecting plate 51 is fixedly connected with the first horizontal power 6; a pressing plate 52 arranged horizontally in parallel with the connecting plate 51 with a longitudinal gap formed therebetween; a first elastic body 53 provided in the gap and elastically supporting the pressing plate 52 with respect to the connection plate 51; a guide rod 54 fixedly connected to the pressing plate 52 and attached to a through hole formed in the connection plate 51; and a return spring 55 which is fitted to the end of the guide rod 54 on the side of the link plate 51 in a pressed state and applies a force to the guide rod 54 to pull the pressing plate 52 toward the link plate 51.
In the present invention, a first extrusion block 5 structure capable of further promoting the efficiency of the arrangement of the multi-strand wire bodies 2 is provided. Specifically, in the implementation process, a telescopic elastic gap is formed between the connecting plate 51 and the pressing plate 52 through the arrangement of the gap and the first elastic body 53, when the first extrusion block 5 presses the multi-strand wire body 2, the multi-strand wire body 2 can obtain a tendency of gathering more towards the limiting block 4 due to the existence of the gap, and the tendency can enable the multi-strand wire body 2 to be arranged relatively higher; when the second extrusion block 7 applies pressure to the first elastic body 53 to deform the first elastic body, the stacked wire bodies 2 are extruded to reduce the gap, so that the multi-strand wire bodies 2 sink to a greater extent, the compactness of the wire bodies 2 is further improved, and the welding effect is ensured. Here, the first elastic body 53 may be a disc spring, so that a more stable supporting state may be obtained, and when it is disposed, a plurality of disc springs may be disposed, particularly, as shown in fig. 7 and 8, in which two disc springs are disposed in parallel.
As another embodiment, as shown in fig. 9, the first compression block 5 includes: the connecting plate 51 is fixedly connected with the first horizontal power 6; and the top of the pressing plate 52 is elastically and rotatably connected with the top of the connecting plate 51, and is arranged at a set included angle with the connecting plate 51 in a natural state. The technical effect similar to the gap setting mode can be achieved through the mode, and the elastic rotating connection can be achieved through the matching of the torsion spring and the rotating shaft structure.
As shown in fig. 10, a control method of a welding apparatus for radial cold joining of a multi-strand wire body as described above comprises the following steps:
s1: cutting off the external pipeline 10; so that the second cylinder and the vertical cylinder can ensure relative independence;
s2: controlling a first piston rod of a first cylinder to extend to a limit position to horizontally extrude the wire body 2, and cutting off an air return pipeline and an air inlet pipeline of the first cylinder to maintain the air pressure in a rod cavity and a rodless cavity of the first cylinder; referring to fig. 3, in this state, when the force applied to the first piston rod is not changed, the first cylinder is in a stable state, and the position can be controlled more accurately by extending the first cylinder to the extreme position;
s3: controlling a second piston rod of a second cylinder to extend to a limit position to realize the extrusion of a second extrusion block 7 on a first extrusion block 5, and cutting off an air return pipeline and an air inlet pipeline of the second cylinder to maintain the air pressure in a rod cavity and a rodless cavity of the second cylinder, wherein at the moment, the extrusion force of the first extrusion block 5 from the second extrusion block 7 is greater than that from the first piston rod, so that the first piston rod retracts for a set distance; in the process, referring to fig. 4, the difficulty of position control can be reduced by extending the second piston rod to the limit position, and the first piston rod can be properly retracted by controlling the extrusion force, so that the multiple strands of wire bodies 2 are instantaneously shaken in the process of instantaneous retraction, and the mutual compaction degree is effectively improved by the shaking, so that the wire bodies 2 are arranged more orderly;
s4: and starting the vertical power 9, so that the third piston rod of the vertical cylinder extends out to the limit position to extrude the limit block 4 and the line body 2. Referring to fig. 5, the press-fixing of the wire body 2 after shaking can be thereby achieved.
As a preferable example of the above embodiment, as shown in fig. 11, after the third piston rod of the vertical cylinder extends to the limit position to squeeze the limit block 4 and the line body 2, the method further includes the following steps:
s5: cutting off an air inlet pipeline communicated with a rodless cavity of the vertical cylinder, controlling the pressure of a rod cavity of the vertical cylinder to be atmospheric pressure, and closing an air return pipeline communicated with the rod cavity; the atmospheric pressure here can be achieved as a result of a separate pressure relief step, or directly during the power take-off performed by the vertical cylinder; of course, if the independent pressure relief step is implemented, the upward thrust applied to the piston of the vertical cylinder during the pressure relief process is reduced, so that the second pressing block 7 may have a proper downward moving tendency, which is advantageous for the present invention because the multi-strand wire body 2 can be impacted and arranged more closely;
s6: communicating the external pipeline 10 to ensure that the pressure of the rod cavity of the vertical cylinder is equal to the pressure of the rodless cavity of the second cylinder; in the process, because the pressure of the rod cavity of the vertical cylinder is atmospheric pressure, and the rodless cavity of the second cylinder is relatively high pressure, the rodless cavity of the second cylinder can generate a proper pressure relief process to reduce the pressure, so that the second extrusion block 7 can be properly retracted, and the first extrusion block 5 can be properly displaced towards the extrusion direction; in the process, the upward thrust applied to the piston of the vertical cylinder in the pressurization process is increased, so that the second squeezing block 7 tends to move upwards, and in the process, the arrangement height of the wire bodies 2 is increased, and the width is narrowed, so that the arrangement is obtained again; in the process, the air return pipeline and the air inlet pipeline of each air cylinder are cut off, and the rearrangement of the stranded wire bodies 2 at the moment of communicating the external pipeline 10 is instantaneous and relatively soft, so that the method is very favorable for the compactness and regular arrangement of the gaps among the stranded wire bodies 2;
s7: and pressurizing the rodless cavity of the vertical cylinder again until the piston rods of the vertical cylinder and the second cylinder extend out to the limit positions. The two cylinders reach the limit positions through pressure control at the position of the rodless cavity of the vertical cylinder, the requirement of the limit positions enables the requirement of the pressure control precision of the rodless cavity to be reduced, in the process of instantaneous pressurization, the second extrusion block 7 can generate displacement instantly horizontally and vertically to extrude the multi-strand wire body 2 again, so that the optimal arrangement state is obtained, and then a power supply can be started to execute the ultrasonic welding process.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
