Description

Technical Field

[0001] The invention relates to an automatic casing expansion and punching machine, belonging to the technical field of casing production equipment, in particular to a semi-automatic device capable of completing the stripping of a steel wire rope from an internal casing and automatically punching the casing. Background Art

[0002] The push-pull cable is a key component commonly used in automobiles. As a mechanism that transmits force and displacement to achieve the unlocking function, its service life affects the car-using experience. Therefore, adding patterns to the push-pull cable and increasing the pull-off force after injection molding are important guarantees for extending its service life.

[0003] At present, when the push-pull cable is punched, the internal tube and the wire rope are peeled off manually, and then the force is stretched forward. After the proximity switch is sensed, the workpiece is punched. However, due to too many uncertain factors in manual operation, the force can be large or small. When it is too small, it cannot be stretched open, and when it is too large, the wire rope will be peeled off too much, resulting in too large a pattern, affecting the appearance of the injection molding, and failing to meet customer requirements.

[0042] Working principle:

[0043] I. First, the casing needs to be placed on the No. 6 bracket 25 manually through the guide groove 30, and the proximity switch 26 on the No. 6 bracket 25 senses whether the casing is placed in the No. 6 bracket 25. At this time, the casing is gently pushed forward manually, aligned with the core rod 20 and inserted into it, so as to locate the inner hole on the casing;

[0044] II. After the sleeve is inserted into the core rod 20, the sleeve is gently pushed. Under the action of the No. 1 spring 14, the core rod 20 and the stripping guide sleeve 21 are pushed until they are pushed to the limit position (that is, the stripping guide sleeve 21 is compressed to be close to but not in contact with one end of the stopper 34 under the action of the No. 2 spring 31), and the proximity switch 26 is sensed. After the proximity switch 26 senses, the clamping cylinder 22 extends to drive the clamping block 23 to clamp the sleeve. At this time, this action needs to be maintained until the clamping cylinder 22 completes the clamping action;

[0045] III. After the compression cylinder 22 is in place, the stripping propulsion cylinder 13 will strip the steel wire rope attached to the memory tube (specifically, the stripping propulsion cylinder 13 stretches, driving the No. 1 spring 14 to stretch, thereby moving the bottom positioning block 6, and then driving the movement of the connecting rod 7, thereby realizing the movement of the core rod 20). During the stripping process, the motor 15 drives the connecting rod 7 to be in a central rotation state (specifically, the motor 15 is started, the output end of the motor 15 starts to rotate, and then drives the rotation of the main pulley 16, and then under the connection of the belt 19, Drive the rotation of the pulley 16, and then drive the rotation of the connecting rod 7, and then drive the rotation of the core rod 20); until the peeling is completed, the entire peeling process is sensed by the positioning switch 29, and after sensing the completion of the peeling action, the patterning cylinder 5 will act (that is, after the output end of the patterning cylinder 5 starts to act, it drives the movement of the connecting sleeve 12, thereby driving the movable plate 3 to move with the assistance of the slider 11 sliding on the guide rail 10); the entire pattern is expanded; after sensing that the pattern expansion is completed, all actions are reset to complete the entire action cycle.
