Description
Technical field
The utility model relates to a kind of mold component, more particularly to a kind of novel pick core print.
Background technique
Currently, needing to pick core print when manufacturing bend pipe tools as shown in Fig. 3；Carry out to the pipe fitting after heating into
Row shaping needs shaping in existing pick after core head mould shapes, and the product after forming need to carry out the Shape correction of ovality, produce
The surplus of irregular, the interior outer arc of the port angular of product is more, and utilization rate of raw materials is low, increases work to later process retaining wall on slope
It measures；Workload increasing is caused, production efficiency is low；Meanwhile it having no idea so that the scrappage of bend pipe tools is promoted.
Utility model content
The purpose of this utility model is according in place of above-mentioned the deficiencies in the prior art, and the utility model aim is realized a kind of new
Type picks core print, which is characterized in that including the first circular cylinder in horizontally arranged length for L1, in the first circular cylinder
Upper surface rear side setting length be L2 the second circular cylinder, the lower end surface of the first circular cylinder rear side be arranged length
For L3, radian is the arcuation circular cylinder of r1, is set as the first fan that radius of central line is r2 in the lower end of the second circular cylinder
The angle of shape circular arc, the first fan-shaped circular arc is a1；The the second fan-shaped circular arc for being a2 in the lower section setting angle of the first fan-shaped circular arc
With third sector circular arc, the radius r3 of the second fan-shaped circular arc is using the lower end surface of the first fan-shaped circular arc as starting point, third sector circle
The radius r4 of arc is using the upper surface of the first fan-shaped circular arc as starting point；The center of circle of described r1, r2, r3, r4 are O point.
Further, the length of the L1 is 100mm-300mm；The length of the L2 and L3 are 25mm-26mm；Institute
The angle of the a1 stated is 60 °；The angle of the a2 is 15 °.
Further, the numerical value of the r1 is 156.5mm-157.0mm；The numerical value of the r2 is 170mm-171mm；Institute
The numerical value of the r3 stated is 126.5mm-127mm；The numerical value of the r4 is 213.5mm-214mm.
Further, the novel core print that picks is mould steel.
The utility model has technical effect that, to redesign for picking core print, changes such as r1 parameter
After, resistance is flowed to when changing pushing after steel pipe heats, the circularity size of core print is changed, increases mold and product is added
The influence of deformation cooling again, makes product keep the size of standard after cooling and shaping after heat.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the main view direction of the utility model.
Fig. 2 is the view of the left view direction of the utility model.
Fig. 3 is the product schematic diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, it is clear that described embodiment is only the utility model a part of the embodiment, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
In conjunction with shown in attached drawing 1, attached drawing 2, provided in the present embodiment it is a kind of it is novel pick core print, it is a kind of novel to pick core
Head, including in the first circular cylinder 1 that horizontally arranged length is L1, the rear side in the upper surface of the first circular cylinder is arranged
Length is the second circular cylinder 2 of L2, and the rear side setting length in the lower end surface of the first circular cylinder is L3；Radian is the arc of r1
Shape circular cylinder 3；The first fan-shaped circular arc 4 that radius of central line is r2 is set as in the lower end of the second circular cylinder；First is fan-shaped
The angle of circular arc is a1；The the second fan-shaped circular arc 5 and third sector circular arc for being a2 in the lower section setting angle of the first fan-shaped circular arc
6；The radius r3 of second fan-shaped circular arc 5 is using the lower end surface of the first fan-shaped circular arc as starting point；The radius r4 of third sector circular arc 6 with
The upper surface of first fan-shaped circular arc is starting point；The center of circle of r1, r2, r3, r4 are O point.
Above-mentioned technical characteristic, after straight tube heating, through A point to B point thermal expansion, bending radius is equal to A value, raw material bore d
Expand to bore D；B point to C point is plastic section, and increase E point and F point flows to resistance, and the metal of inner arc is made to flow to outer arc, guarantees to produce
The uniform wall thickness and bore and port sizes of product meet finished size requirement.Product after solving forming need to carry out ovality
The surplus of Shape correction, irregular, the interior outer arc of the port angular of product is more, and utilization rate of raw materials is low, gives later process groove
