Abstract
The utility model discloses a forming mould for a U-shaped workpiece, which is mainly composed of a concave mould (3) and a convex mould (2), wherein the concave mould (3) is connected to a fixing soleplate (4) by fixing holes (6), the convex mould (2) is connected with a mould shank (1) by fixing holes (7), and the convex mould (2) is matched with a concave mould slot (8) of the concave mould. According to the angle beta and the bending radius R of the U-shaped workpiece, the angle alpha of the convex mould and the radius R1 of the concave mould are computed to manufacture the convex mould and the concave mould, and the concave mould and the convex mould are used for manufacturing the U-shaped workpiece. The utility model has simple structure and convenient use, enables pressure and closing height which are needed by a product during processing and forming in a minor space to be best matched with each other, and solves the problem that an ordinary mould can not process and form the U-shaped workpiece of which the included angle is smaller than 90 DEG and larger than 80 DEG because of the factors of strength and the closing height of a forcing press.
Description
Affiliated technical field
The utility model relates to processing mold, is specifically related to U type workpiece mould.
Background technology
At present, the punch forming angle adopts composite die processing usually less than 90 ° U type workpiece, and the composite die expense is higher, the restriction of the nominal pressure of the machine that is stressed simultaneously, shut height and processing space, and the energy wastes greatly.
Summary of the invention
The purpose of this utility model is: a kind of U type workpiece mould is provided, avoids the low load with strong power energy of composite die to waste problem, reduce die cost.
Technical solution of the present utility model is: this mould mainly is combined into by punch and die; Die is connected on the die fixed base plate, connects die shank on the punch, and punch cooperates with the die groove of die.
According to the ∠ β and the radius of curvature R of U type workpiece, calculate the ∠ α of punch and the radius R of die
1, process punch and die, use this concavo-convex mould promptly can process the moulding angle less than 90 ° of U type workpiece greater than 80 °.
The utility model is simple in structure, with low cost, easy to use, required pressure and shut height best fit in the time of in less space, making product machine-shaping, solved general mould because of intensity and shut height of press machine factor cause can not the machine-shaping angle less than 90 ° of problems greater than 80 ° of U type workpieces.
Description of drawings
Fig. 1 is the utility model die assembly figure I
Fig. 2 is the utility model die assembly figure II
Fig. 3 is U type workpiece moulding figure
Among the figure: 1 die shank, 2 punch, 3 dies, 4 fixed base plates, 5 supports, 6,7 fixing holes, 8 die grooves
The specific embodiment
As shown in Figure 1, this mould mainly is made up of punch 2 and die 3, and die 3 is connected on the fixed base plate 4 through fixing hole 6, and punch 2 connects die shank 1 through fixing hole 7, and punch 2 cooperates with the die groove 8 of die.
As shown in Figure 2, die 3 is connected on the fixed base plate 4 through support 5.
According to the ∠ β and the radius of curvature R of U type workpiece, calculate the ∠ α of punch and the radius R of die
1, process punch and die, use this concavo-convex mould processing U type workpiece.
As: process a U type workpiece ∠ β=80 °, during R=70mm, the punch ∠ α of design processing is chosen between 86 °～87 °, die R1=2～3mm, when demoulding difficulty then during less than converted products below 85 °, influence working (machining) efficiency, die R with punch ∠ α design
1Also same problem will appear greater than 4mm when above, R1 during less than 1mm then product be difficult to moulding.
Claims (3)
1.U type workpiece mould, it is characterized in that: this mould mainly is made up of die (3) and punch (2), die (3) is connected on the fixed base plate (4) through fixing hole (6), and punch (2) connects die shank (1) through fixing hole (7), and punch (2) cooperates with the die groove (8) of die (3).
2. U type workpiece mould according to claim 1, it is characterized in that: die (3) is connected on the fixed base plate (4) through support (5).
3. U type workpiece mould according to claim 1 is characterized in that: according to the ∠ β and the radius of curvature R of U type workpiece, and the ∠ α of calculating punch and 1, the 85 °＜α of radius R of die＜90 °, 0.5mm＜R
1＜5mm.
