Abstract
The utility model discloses automatic core fixing mould in a kind of pipe, comprise core rod body and be located at the matrix on core rod body, the front and back end of described core rod body is respectively equipped with the pilot hole that both sides communicate, balancing spring is provided with in described pilot hole, housing, Compress Spring and head part is arranged with successively at the two ends of balancing spring, described Compress Spring and head part are placed in housing, and head part one is exposed to outside housing; By arranging balancing spring in the pilot hole of core rod body front and back end, and being symmetrical arranged housing, Compress Spring and head part at balancing spring two ends, realizing the effect of core rod body in tubing in automatic core fixing tune.
Description
Technical field
The utility model relates to punching pipes technical field, especially relates to automatic core fixing mould in a kind of pipe.
Background technology
At present, in tubular product punching die technical field, existing tubular product punching die comprises one and inserts the core rod of tubing inside, is to be coordinated with the minim gap of pipe material inner wall by core rod to realize in the tune of core rod in tubing.But if when the matched in clearance amount between them is too small, there is too tight problem by being difficult to insert in tubing or entering in core rod, causes tubing mobile difficulty on core rod afterwards; If matched in clearance amount is excessive, core rod, at tubing Nei Taisong, in causing core rod effectively not adjust in tubing, causes offset raw with upper punch hair, very easily mold damage, thus directly affects product quality and production efficiency.
Utility model content
In order to overcome the defect that traditional core rod exists, the utility model provides automatic core fixing mould in a kind of pipe, can make the core rod in insertion tubing realize automatic core fixing adjust in effect.
The utility model solves the technical scheme that its technical problem adopts: automatic core fixing mould in a kind of pipe, comprise core rod body and be located at the matrix on core rod body, the front and back end of described core rod body is respectively equipped with the pilot hole that both sides communicate, balancing spring is provided with in described pilot hole, housing, Compress Spring and head part is arranged with successively at the two ends of balancing spring, described Compress Spring and head part are placed in housing, and head part one is exposed to outside housing.
As preferably, described housing is cylindric, and housing mouth rim forms stopper to side extension.
Preferably, described head part is steel ball.
The beneficial effects of the utility model are: by arranging balancing spring in the pilot hole of core rod body front and back end, and be symmetrical arranged housing at balancing spring two ends, Compress Spring and head part, when core rod body inserts tubing inside, steel ball on core rod body moves inward, compress Compress Spring simultaneously, under external force, Compress Spring and balancing spring compress simultaneously, under the effect of balancing spring and Compress Spring, the steel ball of core rod body two ends symmetry is stressed identical, due to the balance of two ends power, thus realize the effect of core rod body in tubing in automatic core fixing tune.

Detailed description of the invention
The technical problem solved to make the utility model, technical scheme and beneficial effect are clearly understood, below in conjunction with accompanying drawing and embodiment, are further described the utility model.Should be appreciated that embodiment described herein only for explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1-2, automatic core fixing mould in the utility model one pipe, the matrix 1 comprising core rod body 2 and be located on core rod body 2, the front and back end of core rod body 2 is respectively equipped with the pilot hole 7 that both sides communicate, balancing spring 6 is provided with in pilot hole 7, housing 3, Compress Spring 5 and steel ball 4 is arranged with successively at the two ends of balancing spring 6, Compress Spring 5 and steel ball 4 are placed in housing 3, steel ball 4 one is exposed to outside housing 3, its middle shell 3 is cylindric, and housing 3 mouth rim forms stopper 8 to side extension.
When core rod body 2 inserts tubing inside, steel ball 4 on core rod body 2 moves inward, compress Compress Spring 5 simultaneously, under external force, Compress Spring 5 and balancing spring 6 compress simultaneously, and under the effect of balancing spring 6 and Compress Spring 5, the steel ball 4 of core rod body 2 two ends symmetry is stressed identical, due to the balance of two ends power, thus realize the effect of core rod body 2 in tubing in automatic core fixing tune.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any amendment, on an equal basis replacement and improvement etc. done within spirit of the present utility model and principle, all should drop within protection domain of the present utility model.
