Description
Technical field
The application is related to a kind of core knife retaining mechanism, belongs to substantially without cutting, is added by the metal machinery of line manufacture spring
Work is processed or processing unit technical field.
Background technology
Core knife, cutting knife, pitch knife are the essential parts of spring coiling machine, and first of steel wire holds when core knife is wind spring
Hold a little；Pitch knife is used to control spring pitch；Cutting knife is when spring wind is completed, and coordinates core hilt finished product spring from raw steel
Sheared off on silk, facilitate access for the Winding Cycle of next spring.The core knife of traditional spring coiling machine is often fixed on wallboard center, core
The position of knife and two push rods determines the winding diameter of spring, and to adjust core knife as normal method.In core knife move mode
In, because core knife is to fix locking by screw or helical screw, in operation, with reference to Fig. 1, core knife 2a is consolidated by screw 3a
It is scheduled on support 1a, screw 3a unclamps, and core knife 2a unclamps from support 1a, or helical screw dragging support 1a drives core up and down
Above and below knife 2a；In above process, the moment of steel wire is being cut, cutting knife is very big to support 1a impulsive force, and screw mandrel is easy to damage
Bad, under this percussion, easily there is the phenomenon that pitches in core knife 2a, and causes control not smart；Core pulling can not lock, and locking can not
Core pulling.
Based on this, the application is made.

Cushion block three is relative, and locking small end junction loosens, tighten for the arc-shape synchronous level in the center of circle.
Described oil cylinder output end sets push rod, push rod and locking connecting rod axis connection.Oil cylinder as power take-off unit, its
Mobile motive power source is provided for locking connecting rod, can moving horizontally push rod directly by the axis connection of push rod and locking connecting rod
The swing of locking connecting rod is converted into, facilitates the arrangement of each workpiece space position, is also beneficial to the efficient progress of transmission.
Connecting shaft one is installed between described locking connecting rod and locking gag, installed between synchronising (connecting) rod and locking gag
There is connecting shaft two.Lock connecting rod, synchronising (connecting) rod and lock axis connection mode between gag, both facilitate the stabilization of transmission process
Property, avoid transmission caused by rigid connection from stagnating, be improved the flexibility of transmission process.
Described rotating shaft one, rotating shaft two are connected through support with cushion block.Core knife, support and cushion block are set gradually, locking
Gag be arranged in parallel with cushion block, rotating shaft one, the setting of rotating shaft two, both provides rotating fulcrum for locking connecting rod and synchronising (connecting) rod,
Cushion block is realized again with locking the cooperation of gag, it is ensured that is synchronized with the movement.
The application is applied in the assembling of core knife, oil cylinder by the stretching of push rod, contract, promote locking connecting rod to swing, by
With synchronising (connecting) rod upper end with locking gag axis connection in the middle part of locking connecting rod（That is connecting shaft one, connecting shaft two）, lock connecting rod
Lower end and synchronising (connecting) rod lower end with support, cushion block axis connection（That is rotating shaft one, rotating shaft two）, this structure, both ensure that locking
Connecting rod and the uniformity and synchronism of the linkage of synchronising (connecting) rod two-stage, locking connecting rod do parallel pendulum with synchronising (connecting) rod around respective axle
Dynamic, under the cooperation by locking gag and cushion block, support, locking gag, core knife and cushion block are with push rod and locking connecting rod axis connection
Locate to loosen, tighten for the arc-shape synchronous level in the center of circle, fix that existing " core pulling can not be locked, locked so as to avoid conventional screw
It is unable to core pulling " phenomenon；Meanwhile cushion block and locking gag separation core knife both sides, the setting of gag ramp is locked, can be in stress mistake
Realize and compress in journey, so as to improve the stability of installation.
