Pressing type heating needle cage

Abstract

The invention discloses a pressing type heating needle cage. The pressing type heating needle cage comprises a needle cage body, and a heating groove is formed in the needle cage body. A plurality ofexpanding holes are formed in the two sides of the heating groove, and a stirring rod is arranged in each expanding rod. An upper limiting block is arranged at one end of each stirring rod and arranged outside the corresponding expanding hole, and a lower limiting block is arranged at the other end of each stirring rod and arranged in the corresponding expanding hole. The upper limiting blocks areconnected with upper reset springs. One end of each lower limiting block penetrates out of one side wall of the heating groove and abuts against the lower limiting block on the other side wall of theheating groove. Lower reset springs are arranged at the other ends of the lower limiting blocks. When the stirring rods are pushed by expanding plates, the stirring rod cannot incline, it is avoidedthat the lower limiting blocks move to be blocked, and the lower limiting blocks on the two sides of the heating groove can be fast and smoothly moved to be separated.

Description

technical field [0001] The invention relates to the field of glasses manufacturing equipment, more specifically, it relates to a pressing type heating needle cage. Background technique [0002] In order to make the spectacle legs of the spectacle frame bend further during use and prolong the service life of the spectacle legs, the spectacle legs are generally composed of spectacle leg plastic parts and spectacle pin pins, and usually a pair of glasses is inserted into the spectacle leg plastic parts Pin pins, when the pins are inserted into the plastic parts of the spectacle feet, the inserts usually need to be heated. After the heating is completed, the pins need to be pushed out of the heating needle cage. The main body of the needle cage is provided with a heating groove; both sides of the heating groove are provided with several opening holes, each opening hole is provided with a toggle rod, and one end of the toggle rod is placed on the support Outside the opening, the...

[0002] In order to make the spectacle legs of the spectacle frame bend further during use and prolong the service life of the spectacle legs, the spectacle legs are generally composed of spectacle leg plastic parts and spectacle pin pins, and usually a pair of glasses is inserted into the spectacle leg plastic parts Pin pins, when the pins are inserted into the plastic parts of the spectacle feet, the inserts usually need to be heated. After the heating is completed, the pins need to be pushed out of the heating needle cage. The main body of the needle cage is provided with a heating groove; both sides of the heating groove are provided with several opening holes, each opening hole is provided with a toggle rod, and one end of the toggle rod is placed on the support Outside the opening, the other end is placed in the opening hole and the end is provided with a limit block; one end of the limit block passes through the limit block on one side wall of the heating tank and the other side wall of the heating tank Contradictory, the other end of the limit block is provided with a return spring; when it is necessary to push the pin out of the cage body, the expansion plate moves forward and is placed between the toggle rods on both sides of the heating tank. At this time, the heating tank The toggle levers on both sides will be forced to move towards the other side of the opening hole respectively, and compress the return spring, thereby driving the limit blocks on both sides of the heating tank to separate, and at this time the limit blocks on both sides of the heating tank are released from the mating The pin is limited so that the pin can be quickly and smoothly pushed out from the heating tank, but only one end of the toggle rod placed in the limit hole is under the elastic force of the return spring, and the other end is not stressed. When this end is pushed by the expansion plate, it is easy As a result, the toggle lever is tilted, causing the limit block to jam, so that the limit blocks on both sides of the heating tank cannot move quickly to achieve separation
