Abstract
The utility model relates to a hot stamping die positioning and supporting device with the function of heat insulation, which comprises a spring, a positioning pin and ceramic. The positioning pin is in H8/h7 clearance fit with a die, the positioning and supporting device can extend and retract well on the die without falling off under the action of the spring, and the ceramic is fixed to the head of the positioning pin to function in heat insulation, so that local dissipation of a high-temperature sheet is reduced. The head of the positioning pin is provided with limit ribs for positioning installation and slide of the positioning and supporting device. When the die is opened, the head of the positioning pin is positioned on the die, and the high-temperature steel sheet falls off to the ceramic along a bent portion of the head of the positioning pin. When the die is closed, the positioning pin is pressed down along with the steel sheet, and the positioning and supporting device is released from die pressure along with deformation and retraction of the steel sheet, and then is restored to an initial state under the action of the spring.
Description
Technical field
The invention belongs to technical field of hot stamping and forming, relate to a kind of hot stamping die device for positioning and supporting.
Background technology
For the ultra-high strength steel hot stamping forming technology; Core is sheet forming and quenches and carry out simultaneously; Principal character is " two protect " and " two is fast ": " two protect " is suitably to be incubated the plate heating period, the suitable pressurize of shaping stage, and " two is fast " is to move on on the mould fast after the plate insulation; Press fast moving matched moulds, purpose are the complete formation of martensite of abundant austenitizing of plate and drip molding.In high temperature plate transfer process, should shorten the air cooling time, the high temperature plate is put into mould should guarantee as far as possible that the temperature of plate is even as far as possible, guarantees that the temperature drop of high temperature plate is consistent, at the stage fast cooling that quenches.
Because after the high temperature plate was put into mould, its edge directly contacted cooling comparatively fast with mould, causes the phase transformation of plate martensite incomplete easily, the local mechanics poor-performing of drip molding.(application number: a kind of positioner that 200910190878.5) proposes has reduced the contact area of location and high temperature plate to patent " a kind of plate positioner "; Reduced the heat radiation of plate; And for contact portion; Plate is still lowered the temperature very fast, finally can cause the mechanical property of drip molding undesirable, and this positioner more complicated.
Summary of the invention
The present invention proposes a kind of hot stamping die device for positioning and supporting with adiabatic function, problems such as high temperature plate temperature drop is inhomogeneous to solve, device for positioning and supporting complicacy.
Above-mentioned purpose implementation method of the present invention is explained as follows:
The present invention relates to a kind of hot stamping die device for positioning and supporting with adiabatic function, this device for positioning and supporting is made up of spring, alignment pin and pottery.
A kind of hot stamping die device for positioning and supporting with adiabatic function; Form with pottery (1) by spring (4), alignment pin (2); It is characterized in that said alignment pin (2) head is equipped with pottery (1), said spring (4) is installed in alignment pin (2) bottom.
Further, a kind of hot stamping die device for positioning and supporting with adiabatic function is characterized in that said alignment pin (2) head contains spacing muscle (3).
Alignment pin and mould adopt the matched in clearance of H8/h7; Under the effect of spring (4), device for positioning and supporting can stretch preferably on mould (5) and be unlikely to come off, and pottery (3) is fixed on the head of alignment pin (2); Play heat insulating function, reduce the local heat radiation of high temperature plate.Alignment pin (2) head contains spacing muscle (3), and positioning action is played in the installation and the slip of device for positioning and supporting.During the mould openings state; Alignment pin (2) head is positioned on the mould (5), and high temperature steel plate (6) is along with the sweep of alignment pin (2) head comes off on pottery, when mould (5) is closed; Alignment pin (2) is along with high temperature steel plate (6) is depressed; Along with the distortion of high temperature steel plate (6) is shunk, device for positioning and supporting no longer receives the die pressure effect, under the effect of spring, returns to original state.
Description of drawings
Fig. 1 is a kind of hot stamping die device for positioning and supporting sketch map with adiabatic function involved in the present invention;
Fig. 2 is the sketch map of device for positioning and supporting when mold position.
Among the figure: 1, pottery; 2, alignment pin; 3, spacing muscle; 4, spring; 5, hot stamping die; 6, high temperature steel plate.
