The core print device has simple structure, easy manufacture and processing, good technical stability, high efficiency and high quality of bent tubes, is especially applicable to the forming processing of various bent tubes and continuous and large-scale production, and is mainly applied to the forming of cold bending of thin-wall round tubes.
Description
[technical field]
The utility model relates to metal tube brake forming field, especially relates to the core print device technique field of cold conditions bend pipe moulding.
[background technology]
In the bend pipe molding procedure of air-condition heat exchanger manufacturing, need to use bending machine to realize, the existing bending machine that bends the heat exchanger light-wall pipe is employing activity core print generally, to adapt to the needs of different tube diameters, different radius bend, as shown in Figure 1, it comprises core bar 20 and rotary bulb 10, but movable core print has following shortcoming: complex structure, manufacture difficulty is big, service life is short, and ball head divides and come off easily, has the risk that causes air-conditioning system to stop up.Therefore, some external heat exchanger manufacturers below wall thickness 0.4mm the pipe of (d5-9.52mm) adopt whole rigid core print, to overcome these shortcomings of movable core print.Shown in Fig. 2,3, Fig. 2 is that head 30 is hemispheric bulb, structure is comparatively simple, the main thin-wall circular tube of using little caliber, big radius bend bends, but, the contact area of this class bulb and tube wall is too little, when bending the little pipe of big caliber, radius bend, occurs problems such as curved disconnected or cockle easily.The bulb 40 of second kind of rigid core print shown in Figure 3 is an asymmetric design, its external appearance characteristic more complicated, though but range of application is wider in theory, but generally its camber line place curved surface needs technological experiment repeatedly obtains, design difficulty is bigger, the historical facts or anecdotes border is used extensive not as first kind of core print on the contrary, except the big shortcoming of design difficulty manufacture difficulty, such core print also has following problem: 1, it or not the circumference symmetrical structure, relatively stricter to setting angle, the direction of camber line bending must be consistent with wrap direction, and this difficulty when bending elongated pipe is bigger, and technology stability is bad; 2, head dimensions is big, gets stuck easily when bending the serious pipe of reducing, is not suitable for large-scale continuous production.
Therefore, provide a kind of and save manufacturing cost, technology is simple, service life of equipment is long, core print device simple in structure, that be widely used in various bend pipe processing and forming is real in necessary.
[summary of the invention]
The purpose of this utility model be to provide a kind of simple in structure, make handling ease, technology stability is good, the bend pipe formation highly effective the is high-quality core print device that is used for bending machine, it is applicable to various bend pipe processing and forming, be applicable to continuous, large-scale production, it is mainly used in the moulding of thin-wall circular tube cold conditions bend pipe.
For realizing the utility model purpose, provide following technical scheme:
The utility model provides a kind of core print device that is used for bending machine, it comprises fixedly connected core bar and bulb, this bulb forward outer surface is a sphere, the sphere of bulb is connected with the arc transition face with core bar, and the sphere of bulb and arc transition face connect into ellipsoid or near the ellipsoid structure on the whole structure.The design of this arc transition face has guide effect in the bend pipe moulding, particularly more suitable at the serious soft attitude metal of reducing, and this arc transition face helps to increase the contact area of bulb and tube wall, plays shaping operation, makes the bent pipe forming technology better effects if.Have this core print device and be axially symmetric structure, lower to installation requirement, go for bending elongated light-wall pipe, be applicable to bending of elongated tubular.
Be provided with jet at bulb and core bar junction, two of operated by rotary motion arrive a plurality of jets, be provided with the cavity that communicates with jet in this core bar, oil is sprayed by jet then from the cavity input, make that each face all lubricates evenly between core print device and the tube wall, can reduce the loss of processing oil to a certain extent.
Be connected with bending machine during for use, the cavity of this core bar afterbody is provided with the installation screw thread.And easy for installation for operation, this core bar is provided with auxiliary installed surface, and this auxiliary installed surface is the rectangular recess that is arranged on the core bar both sides.This bulb and core bar junction are provided with escape.Directed convenient during for installation, can also be provided with spigot surface at the core bar afterbody.
The contrast prior art the utlity model has following advantage:
The utility model core print apparatus structure is simple, make handling ease, technology stability is good, the bend pipe formation highly effective is high-quality, significant prolongation the service life of equipment and spare part, saved manufacturing cost, avoided the problem of using soft core print to get stuck easily, it is applicable to various bend pipe processing and forming, be applicable to continuous, large-scale production, it is mainly used in the moulding of thin-wall circular tube cold conditions bend pipe.
