Abstract
An elastic positioning structure of a large-radian forming part comprises a lower die base, a lower convex die, a first outer tube position and a second outer tube position, wherein the lower convex die is arranged on the lower die base, four first outer tube positions which are opposite in pairs and fixed on the lower die base are arranged on two sides of the lower convex die, and two second outer tube positions which are opposite in pairs and fixed on the lower die base are arranged on the other two sides of the lower convex die; the first outer pipe position is provided with a through hole with a right-angled trapezoid cross section, the lower bottom of the through hole is positioned on the inner side of the outer pipe position, and the right-angled waist of the right-angled trapezoid is positioned on the upper part; the wall of the right trapezoid through hole is close to the upper bottom of the right trapezoid, a support rod is rotatably mounted at the upper bottom of the right trapezoid, and the free end of the support rod extends out of the right trapezoid through hole and is provided with a tension spring between the outer pipe positions above the right trapezoid through hole. The utility model discloses an effect of bracing piece for the flat material can steadily be placed before the shaping, can not incline, and the product yield is high.
Description
Technical Field
The utility model belongs to the technical field of the stamping die technique and specifically relates to a large radian formed part elastic positioning structure.
Background
In the prior art, when a large-scale product is molded in a large radian, the inclined plane is large due to high height; the flat material can not be placed stably before molding, and six outer pipe positions for positioning the product can not well support the flat material, so that the flat material can incline before molding, and the yield of finished products is low.
Thus, the prior art is subject to improvements and improvements.
SUMMERY OF THE UTILITY MODEL
To the weak point among the prior art, the utility model aims at providing an improve big radian formed part elastic positioning structure of finished product yield.
In order to achieve the above purpose, the utility model adopts the technical proposal that:
an elastic positioning structure of a large-radian forming part comprises a lower die base, a lower convex die, a first outer tube position and a second outer tube position, wherein the lower convex die is arranged on the lower die base, four first outer tube positions which are opposite in pairs and fixed on the lower die base are arranged on two sides of the lower convex die, and two second outer tube positions which are opposite in pairs and fixed on the lower die base are arranged on the other two sides of the lower convex die; the first outer pipe position is provided with a through hole with a right-angled trapezoid cross section, the lower bottom of the through hole is positioned on the inner side of the outer pipe position, and the right-angled waist of the right-angled trapezoid is positioned on the upper part; the wall of the right trapezoid through hole is close to the upper bottom of the right trapezoid, a support rod is rotatably mounted at the upper bottom of the right trapezoid, and the free end of the support rod extends out of the right trapezoid through hole and is provided with a tension spring between the outer pipe positions above the right trapezoid through hole.
Compared with the prior art, the beneficial effects of the utility model are that:
due to the adoption of the structural design, namely, the effect of the supporting rod is achieved, the flat plate can be stably placed before forming, inclination is avoided, and the product yield is high.
Drawings
FIG. 1 is a schematic structural diagram of the initial state of the present invention;
FIG. 2 is a schematic structural view of the present invention during molding;
fig. 3 is a top view of the present invention.
The reference numbers in the figures are respectively: 1. the lower die holder, 2, lower punch, 3, first outer tube position, 4, second outer tube position, 5, right trapezoid through-hole, 6, bracing piece, 7, extension spring.
Detailed Description
The invention will be described in further detail with reference to the accompanying drawings:
referring to fig. 1-3, the elastic positioning structure for large-arc-shaped parts of the present invention comprises a lower die holder 1, a lower punch 2, a first outer tube position 3 and a second outer tube position 4, wherein the lower punch 2 is disposed on the lower die holder 1, four first outer tube positions 3 fixed on the lower die holder are disposed on two sides of the lower punch 2 in a pairwise opposite manner, and two second outer tube positions 4 fixed on the lower die holder are disposed on the other two sides in a pairwise opposite manner; the first outer pipe position 3 is provided with a through hole 5 with a right-angled trapezoid cross section, the lower bottom of the through hole is positioned at the inner side of the outer pipe position, and the right-angled waist of the right-angled trapezoid is positioned at the upper part; a support rod 6 is rotatably mounted on the wall of the right trapezoid through hole, close to the upper bottom of the right trapezoid, a free end of the support rod 6 extends out of the right trapezoid through hole, and a tension spring 7 is arranged between the free end of the support rod 6 and the outer pipe position above the right trapezoid through hole; during the shaping, the flat material is followed last shaping and is descended, and the flat material exerts force in the bracing piece for the bracing piece is rotatory, and the extension spring is tensile, and after the shaping, the bracing piece resets under the effect of extension spring, carries out the next material operation of holding in the palm.
The utility model discloses utilize the bracing piece to come to provide the supporting role for the plate material can steadily be placed, and can cooperate the plate material to accomplish the shaping action, guarantees the product finished product yield.
To sum up, the utility model discloses an foretell technical means solves the weak point that exists among the prior art, has reasonable in design, thinks about ingeniously, characteristics such as product yield height.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any person skilled in the art may use the above technical contents to change or modify the above embodiments into equivalent embodiments with equivalent changes.
