Description
Technical field
It the utility model is related to thin-walled parts stamping technology field, and in particular to a kind of stamping drawdown with heat insulation function
Mould positioning component.
Background technology
When carrying out punch process for the thin-walled parts of titanium alloy class, the Sheet Metal Forming Technology that uses is processed to extend, and is struck out
Product diameter after type is big and the depth of cavity is small, and the wall thickness of product is less than two millimeters；Processed using cold forming Sheet Metal Forming Technology
Product oral area gradient it is big with ovality, do not meet product requirement, and product size and form tolerance are not easy to ensure,
Therefore difficulty of processing is very big.Needed if using hot forming Sheet Metal Forming Technology by spread material be heated to needed for temperature place into it is convex
In the mould location-plate of extending of mould, temperature can vary over during spread material shifts, and mould positioning of extending
The larger temperature difference between plate and spread material be present, it is difficult to temperature during to punching press realizes control, cause product after punch forming
Yield rate is very low.
Utility model content
In view of this, the utility model provides a kind of stamping drawdown mould positioning component with heat insulation function, by right
Mould location-plate of extending be heated to the temperature of technological requirement, then carries out punch process to spread material, it is ensured that spread material adds
The yield rate of work shaping.
A kind of stamping drawdown mould positioning component with heat insulation function, the positioning component include lower template, punch-pin, positioning
Plate, heater strip, heat-insulation layer and backplate；
The bottom of the punch-pin is fixedly connected in lower template, and punch-pin upper end is the forming surface of arc；The location-plate is
Cirque structure, location-plate are fixedly connected in lower template, and the upper surface of location-plate is machined with the locating slot of holding and expanding material, fixed
Annular groove is machined with the outer circumference surface of position plate, and the bottom coiling heater strip of annular groove, heater strip outer wrap heat-insulation layer is described
Heat-insulation layer and heater strip are fixed in annular groove by backplate.
Further, the location-plate is sleeved on the outer circumference surface of punch-pin and is fixedly connected by screw rod with lower template,
The cooperation of location-plate and punch-pin can ensure the concentricity of location-plate and punch-pin, while ensure that the positioning precision of spread material.
Further, the backplate is fixedly connected on location-plate by screw.
Further, the heater strip uses nichrome heating wire.
Further, the heat-insulation layer uses asbestos material.
Beneficial effect：
Positioning component of the present utility model is incubated using heater strip and heat-insulation layer to the location-plate after heating, spread material
Punching press can be completed under the conditions of suitable technological temperature, formation of parts oral area obtains without tilt phenomenon, size and ovality
Further improve.Location-plate by heat-insulation layer auxiliary heating after can preferably play insulation effect, ensure that spread material heat into
The yield rate of shape.

Embodiment
With reference to the accompanying drawings and examples, the utility model is described in detail.
As shown in Figure 1, the utility model provides a kind of stamping drawdown mould positioning component with heat insulation function, and this is fixed
Hyte part includes lower template 10, punch-pin 9, location-plate 5, heater strip 1, heat-insulation layer 2, screw 4 and backplate 3；
The bottom of punch-pin 9 is fixedly connected on 10 in lower template, and the upper end of punch-pin 9 is the forming surface of arc；Location-plate 5 is annulus
Shape structure, location-plate 5 are sleeved on the outer circumference surface of punch-pin 9 and are fixedly connected by screw rod with lower template 10, location-plate 5 it is upper
Surface Machining has the locating slot of holding and expanding material, and annular groove is machined with the outer circumference surface of location-plate 5, as shown in Figure 2, annular
The bottom coiling heater strip 1 of groove, the outer wrap heat-insulation layer 2 of heater strip 1, backplate 3 are wrapped in the outside of heat-insulation layer 2 and by heat-insulation layers
2 and heater strip 1 be fixed in annular groove, backplate 3 is fixedly connected by screw with location-plate 5.
The present embodiment carries out punch process to the titanium alloy spread material that thickness is 1.2mm, will be fixed first with firing equipment
Position plate 5 is heated to the temperature of technological requirement, and spread material 8 is placed in the locating slot of location-plate 5 rapidly, recessed in top plate 6
Mould 7 moves downward matched moulds solid, and top plate 6 is by the inner chamber of part pushing piece cavity plate 7 after die sinking, with regard to this whole punch process mistake of completion
Journey.
In summary, preferred embodiment of the present utility model is these are only, is not intended to limit of the present utility model
Protection domain.All any modification, equivalent substitution and improvements within the spirit and principles of the utility model, made etc., all should be wrapped
It is contained within the scope of protection of the utility model.
