If the moving track of the pressure head 53 needs to be adjusted according to the specification of the reducing spring, the adjusting bolt 9 is driven to rotate when the adjusting bolt 9 is rotated, the extension rod 7 is driven to slide along the second sliding groove when the adjusting bolt 9 rotates, so that the height along the bottom end of the long rod is moved downwards, the effective length of the incomplete rack 541 is adjusted by rotating the adjusting bolt 9, and the running time of the driving assembly 54 is adjusted, so that the moving track of the pressure head 53 is adjusted;
When a conventional spring is processed, the way of changing the track of the pressure head 53 through the driving assembly 54 is not applicable any more, at this time, the incomplete rack 541 is pushed upwards firstly, at this time, the guide screw 547 and the adjusting nut 548 on the guide screw 547 move upwards along with the incomplete rack 541, then the adjusting nut 548 is rotated until the adjusting nut 548 is clung to the guide sleeve seat 58, at this time, the adjusting nut 548 limits the guide screw 547, the incomplete rack 541 cannot move downwards to reset, then when the mounting seat 52 drives the pressure head 53 to move downwards, the bottom end of the incomplete rack 541 does not contact with a horizontal reference surface on the base block 6, the moving track of the pressure head 53 is not affected, at this time, if the position of the pressure head 53 needs to be adjusted, the gear 544 can be manually rotated, the driving screw 542 is driven to rotate when the gear 544 is rotated, and then the position of the pressure head 53 is adjusted, and the conventional spring with different specifications can be applicable;
Through setting the shutdown mechanism 5 as cutter 51, mount pad 52, pressure head 53 and drive assembly 54, when needs cut off the reducing spring after the shaping, utilize mount pad 52 and drive assembly 54 control pressure head 53's removal orbit, avoid reducing spring tail end second circle steel wire when making pressure head 53 move down earlier, avoid contacting the second circle steel wire in advance and cause reducing spring distortion, make pressure head 53 extend to reducing spring tail end and reducing spring tail end in the clearance between the second circle, guarantee that pressure head 53 can cover the steel wire of reducing spring tail end completely, avoid pressure head 53 wearing and tearing reducing spring through this kind of mode, also avoid leading to the problem of spring distortion or decentration because of the extrusion reducing spring, effectively improved the processingquality of reducing spring, still reduced the unnecessary wearing and tearing of pressure head 53 simultaneously, improved pressure head 53's life.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
