Embodiment 3
The present embodiment provides heating systems and loading system feeding distance that a kind of dynamic point heats progressive molding device
Determine method, as illustrated in figures 4-5：
The feed motion of heating system and loading system is divided into the horizontal feed of the vertical feed campaign and X-axis or Y-axis of Z axis
Movement.The vertical feed campaign of Z axis provides loading force for the deformation of workpiece 9, and Z axis vertical feed distance determines that workpiece 9 is loading
Deflection size under the effect of 10 single-impact of tool, Z axis vertical feed distance is bigger, the load for needing loading tool 10 to provide
Power is bigger, and 11 power of linear servo electric jar is also bigger；The movement of the horizontal feed of X-axis or Y-axis provides heating system and load
System is moved relative to workpiece 9 under required power, X-axis or Y-axis horizontal feed distance and 10 single load of loading tool act on
Workpiece 9 effective deformation area size it is related, X-axis or the more big then forming efficiency of Y-axis horizontal feed distance are higher, X-axis or Y-axis water
The smaller then forming quality of flat feeding distance is better, thus X-axis or Y-axis horizontal feed distance should consider forming efficiency and at
A compromise optimal value is chosen in the case of form quality amount.
As illustrated in figures 4-5, A, B, C, D are four adjacent points to be formed, i.e. 10 Impulsive load point of loading tool, are also height
The intersection point of energy particle emission pipe 19 axis and 10 axis of loading tool.When the head of loading tool 10 is semiglobe, then have
The shaped region of effect is circle.Assuming that the radius in valid shaping region is R, it is four phases by four circles in the center of circle of A, B, C, D
Adjacent valid shaping region, the factors such as the size of radius R and the vertical feed of Z axis distance, material properties and heating temperature are related,
Only when the X-axis or Y-axis horizontal feed distance of heating system and loading system are less than or equal to AB, BC, CD or AD, just it can guarantee
9 surface each point of workpiece uniformly shapes.Therefore the X-axis or Y-axis horizontal feed of heating system and loading system are apart from the upper limit
It should be noted that the concrete structure design on 10 head of loading tool in the present invention is not with the present embodiment
Limit, as long as the load in workpiece face to be processed can be realized, when 10 head of loading tool is other knots such as cone or square taper
When structure, heating system has similar computational methods with the X-axis of loading system or Y-axis horizontal feed apart from the upper limit.
