Utility model content
In view of this, the purpose of this utility model is to provide a kind of nylon tube reducing flare formation frock, existing to alleviate
Have difficult to the assembling of reducing nylon pipe assembly in technology, need hand assembled, the not good problem of the product quality of assembling.
To achieve these goals, this utility model is employed the following technical solutions：
This utility model provides a kind of nylon tube reducing flare formation frock, including base plate, sizing die cavity and enlarging dress
Put；Multiple sizing die cavities are provided with the base plate, the sizing die cavity is used to place body to be processed；The enlarging dress
It is placed in body to be processed, for expanding internal diameter of tube body to be processed.
Body to be processed is nylon tube.
During use, first body to be processed is put in a sizing die cavity, then the expanding device is inserted
Appropriate location in body to be processed, to reach the purpose for expanding internal diameter of tube body to be processed.
By using this utility model nylon tube reducing flare formation frock, can according to actual needs to Buddhist nun to be processed
Imperial pipe carries out enlarging sizing, facilitates nylon tube to be assembled with joint.
Further, the nylon tube reducing flare formation frock also includes：Support bar；The support bar is two, two
The support bar level and it is parallel be fixed on the base plate, location hole, the sizing die cavity bottom are distributed with the support bar
Portion is provided with locating dowel, and the locating dowel is used to insert in the location hole.
The technical scheme has technical effect that：Support bar is provided with location hole, and sizing cavity bottom is provided with locating dowel, fixed
The fixation of sizing die cavity is realized in the post insertion location hole of position, such conveniently fast disassembling can need to change different rule according to different
The sizing die cavity of lattice.
Further, the nylon tube reducing flare formation frock also includes：Spring；The spring is placed in body to be processed
It is interior.
The technical scheme has technical effect that：First spring is inserted in body to be processed during use, then will be with spring
Body to be processed be put in sizing die cavity, body to be processed is strutted using spring, when preventing from shaping, tubular body subsides.
Preferably, the expanding device is enlarging post；
The enlarging post includes cylinder and head；The head is located at the cylinder front end, and the head is tapered, makes institute
Enlarging post is stated in pencil-shaped.
In this utility model, expanding device can be rustless steel cylinder, or spring.
The technical scheme has technical effect that：By enlarging column production into pencil shape, head is taper, convenient to insert
In body to be processed.
Enlarging post is the enlarging post of different size diameter, can be changed according to actual needs, will be processed with reaching
Expand required internal diameter in body two ends.
Further, the cylinder afterbody of the enlarging post is provided with through hole, is inserted with screw in the through hole.
The technical scheme has technical effect that：The insertion of enlarging post inserts screw, head of screw in afterbody after being processed body
Portion's contact base plate, prevents enlarging post from inserting enlarging post resilience in processed pipe body by increasing friction.Can also be by base plate
Upper setting bumping post, blocks screw and reaches the purpose for preventing enlarging post resilience.
Further, the sizing die cavity is set to bent groove structure, described fixed for processed body is processed into
The structure of type die cavity.
Preferably, shape die cavity groove internal diameter 1mm～3mm bigger than the external diameter of body to be processed, make body to be processed with
The groove of sizing die cavity coincide and arranges.
Preferably, the depth of groove of sizing die cavity is not less than 2/3rds of pipe diameter to be processed.
The technical scheme has technical effect that：As the nylon tube for automotive fluid pipeline is frequently not straight type,
Generally need to be fixed to bending in being actually needed, sizing die cavity is made into the bending groove structure with knuckle, can be by
, into required form, sizing die cavity is equivalent to mould, thus it is possible to vary its bending degree and angle, to obtain not for processed pipe body-shaping
The nylon tube of similar shape demand.
Further, the column diameter of the enlarging post is more than internal diameter of tube body to be processed.
The technical scheme has technical effect that：Enlarging post column diameter is expanded with reaching enlarging more than internal diameter of tube body to be processed
The purpose of large diameter, enlarging post column diameter can be set according to actual needs.
Preferably, the enlarging post is set to bent structure.
Straight type enlarging post is suitable for insertion into body one or both ends, to enlarging is carried out at body both ends open, but it is actual
In can need to carry out body bending part enlarging, straight type enlarging post does not often reach this requirement.
In order to solve this problem, enlarging post is set to into bent structure, this bent structure is with body in sizing
Bending structure matching in die cavity so that enlarging post is inserted into body bending part, then according to enlarging needs, is needing to expand
The position of mouth increases enlarging column diameter, to reach in the expanding purpose of body bending place or body other positions.
The technical scheme has technical effect that：Enlarging post is set to into bending structure, it is possible to achieve to body bending part
It is expanding.
Further, the nylon tube reducing flare formation frock also includes：Give as security clamp device；The signature clamp device is for by institute
State enlarging post to push in processed pipe body.
Wherein, it is toggle to give as security clamp device；Toggle includes：Connecting rod, depression bar and contiguous block；It is described
