Description
Technical field
The present invention relates to a kind of refrigeration pipeline part processing mold more particularly to a kind of refrigeration pipeline part flaring dies.
Background technique
In refrigeration pipeline part welding field, often need to be flared refrigeration pipeline part port, the operation of necking or flat mouth,
To meet the needs of two root canal group grafting assembly, in enlarging apparatus field, processing method in the prior art is to directly adopt expansion
Mouthful formed punch line up carries out the molding that swells, directly adopt formed punch processing method easily lead to it is bad as follows:
(1) outer diameter can not guarantee after being flared, and weld if it is being plugged into the pipe group of thick bore after flaring, assemble
The bad control in gap, it may occur that leakage；
(2) the flared section depth of parallelism can not guarantee, formed punch, which is directly flared, will cause metal tube extrusion deformation.
Summary of the invention
Present invention aims to overcome that the problems of the above-mentioned prior art and provide one kind can guarantee flaring after outer diameter
The refrigeration pipeline part flaring die of size.
In order to solve the above technical problems, the present invention adopts the following technical scheme that:
A kind of refrigeration pipeline part flaring die, including flaring die and formed punch, the flaring die are made of upper die and lower die,
The upper mold is equipped with the first holding tank, and the first flaring slot runs through first holding tank, is equipped with the second clamping in the lower die
Slot, the second flaring slot run through second holding tank, and first holding tank is identical as second holding tank, and described first expands
Mouth slot is identical as the second flaring slot, the holding tank diameter and system that first holding tank is formed after merging with the second holding tank
Cold pipeline fitting outer diameter is identical, the flaring slot diameter and refrigerator pipes that the first flaring slot is formed after merging with the second flaring slot
Road part flaring size is consistent, and the outer diameter of the formed punch is the wall thickness that refrigeration pipeline part is flared that diameter subtracts refrigeration pipeline part.
Preferably, the length of the first flaring slot and the second flaring slot is consistent with refrigeration pipeline part flaring length.
Compared with prior art, the invention has the benefit that
A kind of refrigeration pipeline part flaring die of the present invention, uses flaring die and punch structure, is wherein arranged on flaring die
Perforative holding tank and flaring slot, be flared slot diameter be flared with refrigeration pipeline part after diameter it is consistent, in formed punch punching course
In, refrigeration pipeline part ensures outer dimension and straightness after flaring under the limit of flaring slot, effectively raises refrigeration
The precision of the fitted position of pipe fitting.

Specific embodiment
Referring to shown in attached drawing 1-4, a kind of refrigeration pipeline part flaring die, including flaring die and formed punch 1: the flaring die
It is made of upper mold 2 and lower die 3, the first holding tank 2-1, the first flaring slot 2-2 is equipped in the upper mold 2 through first folder
Slot 2-1 is held, is equipped with the second holding tank 3-1 in the lower die 3, the second flaring slot 3-2 runs through the second holding tank 3-1, described
First holding tank 2-1 is identical as the second holding tank 3-1, the first flaring slot 2-2 and the second flaring slot 3-2 phase
Together, the holding tank diameter and refrigeration pipeline part outer diameter phase that the first holding tank 2-1 is formed after merging with the second holding tank 3-1
Together, the flaring slot diameter and refrigeration pipeline part that the first flaring slot 2-2 is formed after merging with the second flaring slot 3-2 are flared
Size is consistent, and the outer diameter of the formed punch 1 is the wall thickness that refrigeration pipeline part is flared that diameter subtracts refrigeration pipeline part.
Preferably, the length and refrigeration pipeline part of the first flaring slot 2-2 and the second flaring slot 3-2 are flared length one
It causes.
In use, being first depending on refrigeration pipeline part specification to be processed designs the first holding tank 2-1, the first flaring slot
The diameter and length dimension of 2-2, the second holding tank 3-1, the second flaring slot 3-2 and formed punch 1, the present invention are to ensure refrigeration pipeline part
First flaring slot 2-2 and the second flaring slot 3-2 are designed as and outer diameter after flaring by the outer dimension and straightness of flared end
Unanimously, and the outer diameter of formed punch 1 is that refrigeration pipeline part is flared the diameter of size and subtracts the wall thickness of refrigeration pipeline part, will be of the invention
It is installed on press machine or on stamping equipment, upper mold 2 is specifically connected to cylinder or hydraulic press, lower die 3 is fixed on press machine
Or on the erecting bed of stamping equipment, in installation is coincided with the upper and lower, formed punch 1 is connected to cylinder or hydraulic cylinder and installs for upper mold 2 and lower die 3
In the side of upper mold 2 and lower die 3, when processing, refrigeration pipeline part is placed into the flaring of the second holding tank 3-1 and second of lower die 3
Slot 3-2, upper mold 2 is pushed and is overlapped with lower die 3 under the driving of cylinder or hydraulic press, at this time due to the first holding tank 2-1 and the
Formation holding tank diameter is identical as refrigeration pipeline part outer diameter after two holding tank 3-1 merge, so the refrigerator pipes that can be clamped
Road part, formed punch 1, which advances, at this time is inserted into refrigeration pipeline part in the diameter ruler of the first flaring slot 2-2 and the second flaring slot 3-2
Under very little limit, diameter dimension and straightness are protected after flaring, effectively raise the essence of the fitted position of refrigerating pipe
Degree.
The above description is only the preferred embodiments of the present invention, is not intended to limit the present invention in any other form,
Any person skilled in the art is changed or is modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment.But without departing from the concept of the present invention, above embodiments are done according to the technical essence of the invention
Any simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
