Abstract
The utility model relates to a tubing head end reducing apparatus which is characterized by including a machine body, an upper die arranged on the machine body and being capable of sliding along guide rails of the machine body up and down, and a lower die fixed on the machine body, a clamp for clamping a tubing is arranged on the lower die, and a notch having a diameter equal to the pipe equal to the pipe diameter of the tubing head end after being reduced is arranged in the upper die body. The tubing head end reducing apparatus is simple in structure and reasonable in design, and facilitates the one-step forming of the reducing of the tubing head end.
Description
technical field:
The utility model relates to a kind of machining equipment, particularly a kind of tubing head end undergauge equipment.
background technology:
Tubing, in order to be connected with other parts location, need to carry out undergauge processing at tubing head end, and existing tubing head end undergauge equipment exists that procedure of processing is loaded down with trivial details, production efficiency is low, undergauge is of poor quality wait not enough.
summary of the invention:
The purpose of this utility model is to provide a kind of tubing head end undergauge equipment, and this tubing head end undergauge device structure is simple, reasonable in design, is conducive to convenient processing, improves working (machining) efficiency.
The utility model tubing head end undergauge equipment, it is characterized in that: comprise body, be located at the patrix that can slide up and down along body guide rail on body and be fixedly located at the counterdie on body, on described counterdie, there is the fixture that clamps tubing, in described upper die body, have with undergauge after the suitable notch of tubing head end caliber.
Above-mentioned notch is conical rebate.
Above-mentioned fixture is Self-Centering Clamp.
Above-mentioned fixture is one to have and wear the cylindrical body of through hole for tubing, cylindrical body top is provided with several seam roads that radially cut along it, described patrix bottom is provided with the slotted eye that is inserted in cylindrical body periphery while pressing down in order to patrix, this slotted eye can clamp tubing after hold-down column body when patrix presses down, and described notch is located at the top of slotted eye.
Above-mentioned cylindrical body top has rounded surface.
During the work of the utility model tubing head end undergauge equipment, tubing stretches into fixture from counterdie below, and after clamping, patrix presses down, and under the compacting of notch, the undergauge of tubing head end forms.
The utility model tubing head end undergauge device structure is simple, reasonable in design, is conducive to the undergauge of disposable formation tubing head end.
accompanying drawing explanation:
Fig. 1 is the profile of the utility model tubing head end undergauge equipment;
Fig. 2 is the top view of counterdie in Fig. 1.
the specific embodiment:
The utility model tubing head end undergauge equipment, comprise body 1, be located at the patrix 2 that can slide up and down along body guide rail on body and be fixedly located at the counterdie 3 on body, on described counterdie 3, there is the fixture 4 that clamps tubing, in described patrix 2 bodies, have with undergauge after the suitable notch 5 of tubing head end caliber.
Smooth and easy for undergauge, above-mentioned notch is conical rebate.
In order to facilitate the clamping of tubing, above-mentioned fixture is Self-Centering Clamp.
For reasonable in design, when can make patrix press down, both can realize clamp tubing, can carry out the action of undergauge again, above-mentioned fixture 4 is one to have and wear the cylindrical body 7 of through hole 6 for tubing, cylindrical body top is provided with several seam roads 8 that radially cut along it, described patrix bottom is provided with the slotted eye 9 that is inserted in cylindrical body periphery while pressing down in order to patrix, and this slotted eye can clamp tubing after hold-down column body when patrix presses down, and described notch 5 is located at the top of slotted eye.When patrix presses down, slotted eye 9 is enclosed within cylindrical body 7 peripheries, and slotted eye 9 compresses cylindrical body simultaneously, makes tubing clamped, and notch 5 is suppressed tubing termination portions simultaneously, and tubing termination portion forms undergauge.
Wherein cylindrical body 7 releasable connections are on body 1 counterdie 3.
Above-mentioned cylindrical body top has rounded surface 10, and the interior end of patrix 2 is provided with the circular arc matching with rounded surface 10.
During the work of the utility model tubing head end undergauge equipment, tubing 11 stretches into fixture from counterdie below, and after clamping, patrix presses down, and under the compacting of notch, the undergauge of tubing head end forms.
The utility model tubing head end undergauge device structure is simple, reasonable in design, is conducive to the undergauge of disposable formation tubing head end.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
