fixed guide pin bushing includes the guide pin bushing main part, the inside of guide pin bushing main part is equipped with the toroidal cavity, is equipped with a plurality of steel ball in the toroidal cavity in proper order, the guide pin bushing main part can be stretched out to the head of steel ball, and the afterbody butt of steel ball links to each other through the arc sleeve pipe on a plurality of arc that is the annular distribution between two adjacent arcs.
Furthermore, the clamping device comprises three chucks in an annular array, the heads of the chucks are arc-shaped, and the tails of the chucks are connected with the rack of the extruder through pneumatic telescopic rods.
Furthermore, three positioning holes in an annular array are formed in the end portion of the machine head, positioning columns are arranged in the positioning holes, and the outer ends of the positioning columns abut against the outer wall of the replaceable guide sleeve.
Furthermore, the diameter of the positioning column is gradually reduced from the head part to the tail part.
Furthermore, the number of the steel balls is six.
Further, the replaceable guide sleeve is made of stainless steel.
Has the advantages that:
this device can be used for producing not unidimensional bar with the extruder through changing interchangeable formula guide pin bushing, compares with current whole change mode, and its governing speed is faster, and it is higher to adjust efficiency.

Detailed Description
For the purpose of enhancing the understanding of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.
The PEEK bar forming equipment with the adjustable diameter comprises a machine head 1, wherein a diameter adjusting device is arranged inside the machine head 1; the diameter adjusting device comprises a replaceable guide sleeve 2, a fixed guide sleeve 3 and a clamping device 4;
the fixed guide sleeve 3 and the outer wall of the clamping device are both fixed on a main body frame of the extruder, a center hole matched with a PEEK bar to be formed is formed in the center of the replaceable guide sleeve 2, and a first diameter section and a second diameter section are arranged on the outer ring of the replaceable guide sleeve 2; the outer diameter of the first diameter section is matched with the inner diameter of the fixed guide sleeve 3, and the outer diameter of the second diameter section is smaller than the inner diameter of the machine head;
fixed guide pin bushing 3 includes guide pin bushing main part 31, the inside of guide pin bushing main part is equipped with the toroidal cavity, is equipped with a plurality of steel ball 35 in the toroidal cavity in proper order, the guide pin bushing main part can be stretched out to the head of steel ball 35, and the 35 afterbody butt of steel ball links to each other through arc sleeve 34 on a plurality of is the arc 33 of annular distribution between two adjacent arcs 33.
