When the type of the steel wire ring is changed, only the die seat 5.26 needs to be rotated, and a complex adjusting process is avoided.
The working process of the forming unit 5 is that the forming motor 6.2 is started to synchronously drive the forming shaft 6.6, the cutting shaft 6.4 and the cam shaft 6.5 to provide driving force, and each eccentric shaft sleeve (namely, the eccentric shaft sleeve I5.1, the eccentric shaft sleeve II 5.15 and the eccentric shaft sleeve III 5.25) respectively drives the corresponding tool apron (namely, the tool apron I5.5, the tool apron II 5.17 and the tool apron III 5.20) to reciprocate through the respective internal thread connecting rod (namely, the internal thread connecting rod I5.3, the internal thread connecting rod II 5.13 and the internal thread connecting rod III 5.23); the left top knife 5.7, the cutting knife 5.10 and the right top knife 5.19 reciprocate along the respective linear slide rails (i.e. the linear slide rail two 5.4, the linear slide rail three 5.16 and the linear slide rail four 5.22) along with the respective knife seats. The punching direction of the punching needle is opposite to the bending direction of the flat wire during forming, and the windowing burrs are arranged outside the steel wire ring after forming, so that the burrs are conveniently removed at the later stage.
Referring to fig. 9, the material returning unit has a structure that the material returning unit includes a material returning thimble 7.1 sleeved with a material returning guide 5.9.1, the material returning thimble 7.1 is fixed at the front end of a thimble mounting seat 7.3 by a screw 7.2, the rear end of the thimble mounting seat 7.3 is fixedly connected with the front end of a material returning rod 7.4, the rear end of the material returning rod 7.4 is inserted into a connecting sleeve 7.7, and the connecting sleeve 7.7 is fixed and positioned with the material returning rod 7.4 by two sets of set screws 7.8; a return spring 7.6 is sleeved on the material returning rod 7.4, and two ends of the return spring 7.6 are respectively connected with the connecting sleeve 7.7 and the linear bearing 7.5 in a propping manner; one side of the connecting sleeve 7.7 is fixedly connected with the lower part of the material returning rocking plate 7.9, the middle part of the material returning rocking plate 7.9 is hinged on a fulcrum bearing 7.10, the upper part of the material returning rocking plate 7.9 is provided with a cam follower 7.11, the circumferential surface of the cam follower 7.11 is contacted with the concave-convex surface of a cam 7.12, the cam 7.12 is sleeved at the end part of a cam shaft 6.5, and the cam shaft 6.5 is in driving connection with a forming motor 6.2.
When the cam 7.12 rotates along with the cam shaft 6.5, under the action of the return spring 7.6 and the fulcrum bearing 7.10, the cam follower 7.11 moves along with the outer contour of the cam 7.12, the material returning rocking plate 7.9 swings around the fulcrum bearing 7.10, the material returning rod 7.4 is driven to reciprocate along the linear bearing 7.5, the material returning thimble 7.1 is driven to reciprocate along the outer contour of the core die 5.9, and the formed steel wire ring is pushed out of the processing position on the core die 5.9. Therefore, when the material returning unit works, the core mould 5.9 is fixed, and the steel wire ring which is withdrawn from the core mould 5.9 falls down at a fixed point under the action of the material returning guide 5.9.1, so that the material returning unit is convenient to collect. In addition, the material returning thimble 7.1 similar to the ring shape of the steel wire ring is adopted for returning the material, so that the work is more reliable. The material returning thimble 7.1 is in a semi-ring shape similar to a bead ring, the size of only an inner ring of a series of material returning thimbles 7.1 changes according to the size of a core mold, and the sizes of other matrixes are consistent.
In summary, the device of the present invention adopts a multi-input and multi-output transmission mode, and the power transmission uses a synchronous belt. In order to improve the automation degree of the equipment, a modularized control system is also used in the design. In the scheme, the three motors respectively complete the driving of the corresponding units, and the control system sends commands to the frequency converter and the servo driver through programs to control the three motors.
