Abstract
The invention relates to a pipe expanding mold for round pipes and belongs to the technical field of pipe expanding molds. The pipe expanding mold for the round pipes comprises a pipe expanding mold body, two guide columns, a base plate and a mold plate. The mold plate is located over the base plate. Positioning sleeves are fixed to the left side and the right side of the top of the base plate. Guiding sleeves corresponding to the positioning sleeves are fixed to the bottom of the mold plate. One end of each guide column penetrates into the corresponding positioning sleeve, and the other end of each guide column penetrates into the corresponding guiding sleeve. An expanding mold sleeve is vertically fixed to the bottom of the mold plate. The upper end of the pipe expanding mold body penetrates into the expanding mold sleeve and is fixed to the expanding mold sleeve through a second screw. A discharging mechanism is arranged in the position corresponding to the lower end of the pipe expanding mold body. The parts, between the guiding sleeves and the positioning sleeves, of the guide columns are sleeved with springs. In this way, the pipe expanding mold for the round pipes is simple in structure and can be opened effortlessly, easily and conveniently; the requirement for the lifting capacity of a press is reasonably controlled, and the cost is reduced.
Description
Technical field
The present invention relates to a kind of pipe class expand tube mould, belong to expand tube technical field of mold.
Background technology
At present, when expand tube process is carried out to pipe class pipe fitting, usually adopt and first pipe fitting is fixed on press bench, then by forcing press compression leg head, expand tube is carried out to one end of pipe fitting.Adopt in this way, inconvenient during operation, the center line that sometimes also there will be expand tube end and non-expand tube end not on the same line, causes the pipe fitting decentraction after expand tube.
Inventor has devised a kind of pipe class expand tube mould for this reason, comprise expand tube mould, two guide pillars, base plate and templates, template is positioned at directly over base plate, it is characterized in that: about base plate top, be fixed with positioning sleeve, corresponding positioning sleeve is fixed with guide pin bushing bottom template, guide pillar one end is through in positioning sleeve, the other end is through in guide pin bushing, swollen die sleeve is vertically fixed with bottom template, expand tube mould upper end is through in swollen die sleeve, and fixed by the second screw and swollen die sleeve, corresponding expand tube mould lower end is provided with unloading mechanism.
Find that die sinking is not very convenient in use, require higher to the lifting force of press.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of pipe class expand tube mould, and its structure is simple, and die sinking is light, simple, convenient, reasonably controls the lifting force requirement to press, reduces cost.
Pipe class expand tube mould of the present invention, comprise expand tube mould, two guide pillars, base plate and template, template is positioned at directly over base plate, it is characterized in that: about base plate top, be fixed with positioning sleeve, corresponding positioning sleeve is fixed with guide pin bushing bottom template, guide pillar one end is through in positioning sleeve, the other end is through in guide pin bushing, swollen die sleeve is vertically fixed with bottom template, expand tube mould upper end is through in swollen die sleeve, and fixed by the second screw and swollen die sleeve, corresponding expand tube mould lower end is provided with unloading mechanism, guide pillar between guide pin bushing and positioning sleeve is set with spring, spring one end withstands on guide pin bushing, the other end withstands on positioning sleeve.
Wherein, preferred described unloading mechanism comprises stripper, and corresponding expand tube mould moving direction offers the second through hole on stripper, and stripper is fixed by material returned support plate and base plate.
Conveniently the present invention and forcing press with the use of, described die head is connected with backing plate by the first screw, and backing plate offers the first through hole passed for guide pillar.
The present invention, in order to guarantee the concentricity after pipe fitting expand tube further, described base plate is vertically fixed with plug, and the vertical direction center line of plug and the vertical direction center line of expand tube mould are on the same line.During use, the non-expand tube end of pipe fitting is enclosed within plug, when expand tube die worker does, prevents non-expand tube end because of the punching press generation distortion of expand tube mould further.
The beneficial effect that the present invention has is:
By the present invention, its structure is simple, and die sinking is light, simple, convenient, reasonably controls the lifting force requirement to press, reduces cost.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present invention;
In figure: 1, the first screw 2, template 3, swollen die sleeve 4, backing plate 5, first through hole 6, second screw 7, guide pin bushing 8, expand tube mould 9, guide pillar 10, stripper 11, positioning sleeve 12, material returned support plate 13, base plate 14, plug 15, pipe fitting 16, spring.
Detailed description of the invention
Below by way of specific embodiment, the invention will be further described, but not in order to limit the present invention, all within the present invention's spirit and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
As shown in Figure 1, pipe class expand tube mould, comprise expand tube mould 8, two guide pillars 9, base plate 13 and template 2, template 2 is positioned at directly over base plate 13, template 2 top is connected with backing plate 4 by the first screw 1, backing plate 4 offers the first through hole 5 passed for guide pillar 9, positioning sleeve 11 is fixed with about base plate 13 top, corresponding positioning sleeve 11 is fixed with guide pin bushing 7 bottom template 2, guide pillar 9 one end is through in positioning sleeve 11, the other end is through in guide pin bushing 7, swollen die sleeve 3 is vertically fixed with bottom template 2, expand tube mould 8 upper end is through in swollen die sleeve 3, and fixed by the second screw 6 and swollen die sleeve 3, base plate 13 is vertically fixed with plug 14, the vertical direction center line of plug 14 and the vertical direction center line of expand tube mould 8 are on the same line, corresponding expand tube mould 8 lower end is provided with unloading mechanism, guide pillar 9 between guide pin bushing 7 and positioning sleeve 11 is set with spring 16, spring 16 one end withstands on guide pin bushing 7, the other end withstands on positioning sleeve 11.
In the present embodiment, described unloading mechanism comprises stripper 10, corresponding expand tube mould 8 moving direction offers the second through hole on stripper 10, and stripper 10 is fixed by material returned support plate 12 and base plate 13, material returned support plate 12 and fixing respectively by bolt between base plate 13 and stripper 10.
During use, first backing plate 4 is arranged on the compression leg head of forcing press, base plate 13 is arranged on press bench by corresponding expand tube mould 8 again, then compression leg head is passed through by backing plate 4 pull-up, thus band moving platen 2, swollen die sleeve 3, expand tube mould 8 and guide pin bushing 7 move upward along guide pillar 9, then pipe fitting 15 is vertically enclosed within plug 14, after treating, by compression leg head by backing plate 4 punching press downwards, thus band moving platen 2, swollen die sleeve 3, expand tube mould 8 and guide pin bushing 7 move downward, under expand tube mould 8 acts on, expand tube work is carried out in pipe fitting 15 upper end, after to be done, pass through compression leg head again by backing plate 4 pull-up, now drive pipe fitting 15 moves upward by expand tube mould 8 together, under the effect of stripper 10, pipe fitting 15 is stoped to continue to move upward, thus expand tube mould 8 is separated automatically with pipe fitting 15, play the effect of automatic material returning.
