Abstract
An upper punching device for a crane wheel relates to a thermal molding die and solves the technical problems that a rim is not fully filled or a blank and a die holder are adhered to each other as the thickness of the existing upper punching die of the upper punching device is smaller. The upper punching device for the crane wheel is mainly formed by an upper punching die holder, an upper punching die and a punch. For the thickness of the upper punching die, the thickness is increased under the premise of ensuring that the punch can punch through a thermal state blank. As the thickness of the upper punching die is properly increased, the defects that the upper punching die holder collides with a rim area, or the blank and the die holder are adhered to each other are effectively avoided, and the yield and production efficiency of products are greatly improved.
Description
Technical field
The utility model relates to hot forming tool, relates in particular to a kind of upper hole punched device of driving wheel thermoforming mould.
Background technology
Driving, is called again overhead traveling crane, is a kind of common crane.As shown in Figure 1, the structure of driving wheel is made up of wheel hub 01, disc 02 and wheel rim 03.Have a kind of disc 02 region area of driving wheel less, the width H of wheel rim 03 is larger than the length L of wheel hub 01.
The die forging thermoforming operation of driving wheel is divided into that pier is thick, preformed and punching, and the upper hole punched device playing a major role when punching is made up of upper perforating die seat 1, upper perforating die 2 and drift 3.In production practices process for easy to use, planform and the position of upper perforating die seat 1 and drift 3 are generally fixed, only need to design perforating die 2 (as shown in Figure 2), if the gauge of upper perforating die 2 is too large in design process, when punching, easily cause core material 4-1 to be difficult to be rushed; If the gauge of upper perforating die 2 is too little, when punching, the upper perforating die seat meeting wheel rim region of " damaging ", causes wheel rim face misrun, or blank 4 and die holder 1 " adhesion ", causes demoulding difficulty.Therefore, the thickness of the upper perforating die 2 of correct design is very important.In order to save mold materials and the convenient core material 4-1 that rushes smoothly, manufacturer is the less upper perforating die 2 of used thickness often, like this, in punch process, very easily cause wheel rim to fill discontented, or the shortcoming (as shown in Figure 3) of hot blank 4 and upper perforating die seat 1 " adhesion ".
Utility model content
The purpose of this utility model is intended to overcome the shortcoming of prior art, and a kind of upper hole punched device of driving wheel is provided, and the upper perforating die thickness that solves existing upper hole punched device is less, can cause wheel rim to fill discontented, or makes the technical problem of blank and die holder adhesion.
The utility model is to realize by technical scheme below:
A upper hole punched device for driving wheel, is made up of upper perforating die seat, upper perforating die and drift, it is characterized in that: described upper perforating die, guaranteeing that described drift can rush under the prerequisite of core material of diathermanous state blank, increases its gauge.
The utility model compared with prior art, owing to having strengthened the thickness of upper perforating die, has effectively been avoided the upper perforating die seat wheel rim region of " damaging ", or the disadvantage of blank and die holder " adhesion ", has improved greatly qualification rate and the production efficiency of product.
Accompanying drawing explanation
Fig. 1 is that a kind of rim width is larger than hub length, and the structural representation of the less driving wheel of web area area;
Fig. 2 is the structural representation of upper perforating die;
Fig. 3 is the schematic diagram of hole punched device on existing driving wheel, and in figure, " damaging " and " adhesion " appears in A portion;
Fig. 4 is effect schematic diagram of the present utility model, and in figure, A portion is without " damaging " and " adhesion " phenomenon.
The specific embodiment
The utility model is further described by embodiment below in conjunction with accompanying drawing:
As shown in Figure 2,4, a kind of upper hole punched device of driving wheel, is made up of upper perforating die seat 1, upper perforating die 2 and drift 3, and described upper perforating die 2, guaranteeing that drift 3 rushes under the core material 4-1 prerequisite of diathermanous state blank 4, increases its gauge h.
The utility model is the main disadvantages in hot punch process for existing apparatus: the upper perforating die seat wheel rim region of " damaging ", cause depression or the misrun of the out-of-flatness of wheel rim face and wheel rim outer radius; Hot blank and die holder " adhesion " cause the extremely difficult problem of the demoulding.Strengthen the thickness of upper perforating die, efficiently solved the problem that existing mold causes, improved greatly the qualification rate of product.
Claims (1)
