Abstract
The invention discloses a device and a method for manufacturing a CH hole of an automobile panel, the manufacturing device comprises a drawing convex mould and a drawing concave mould, a bottom hole is arranged on the drawing convex mould, and a CH hole punching concave mould is arranged in the bottom hole; a space is opened on the corresponding position of the drawing concave mould, and a CH hole punching convex mould mechanism is arranged in the space, wherein the CH hole punching convex mould mechanism comprises a CH hole punching convex mould, a spring and a cylinder component; the CH hole punching convex mould and the drawing concave mould are slidingly matched and guided, the CH hole punching convex mould is supported by the spring so as to guarantee that the CH hole punching convex mould cannot expose out from a concave mould forming profile during working; the CH hole punching convex mould is driven by the cylinder component during punching. By adopting the invention, the device cannot be deformed during punching; and the secondary location problem of a drawing component caused by adopting a conventional method does not exist, and the manufactured CH hole has excellent position consistency.
Description
Technical field
The invention belongs to the technical field of manufacturing technology equipment, especially relate to the preparation method and the device thereof in a kind of automobile panel CH hole.
Background technology
The CH hole is meant that grinding mould uses fabrication hole, adopts the CH hole to carry out the product location when grinding mould, can guarantee the uniformity of preface location, diel front and back, thereby reach the purpose that guarantees part accuracy.Functional hole on the non-final products in CH hole, after die debugging was stable, the CH hole need be blocked up, in case on part, leave a trace, influences the surface quality of vehicle exterior cladding element.
The conventional preparation method in the CH hole of diel producer employing at present is:
When mould is made, the piercing punch installation site is set drawing on the die, punching concave die is set drawing on the punch;
During towards the CH hole, go out drawn component earlier, load onto piercing punch on the die drawing then, the drawn component that will go out again is reentered into and goes out the CH hole in the drawing die.
Though this preparation method can be gone out the CH hole comparatively accurately, has following problem:
During towards the CH hole, CH hole periphery material fails to compress, and there is distortion in the CH hole that causes going out;
Owing to be to go out drawn component earlier, treat that piercing punch is loaded onto after, drawn component drops into drawing die again and goes out the CH hole, this will have product because the inconsistent bad problems of each product CH hole site uniformity that causes of situation such as location during input and product bounce-backs.
Summary of the invention
The present invention is exactly the problem that exists to above conventional CH hole preparation method, provide a kind of in the stamping die of automotive covering part debug process high-precision CH hole producing device and preparation method.
To achieve these goals, the invention discloses the producing device in a kind of automobile panel CH hole, comprise and draw punch and draw die, offer bottom outlet on the punch drawing, CH hole punching concave die wherein is installed; Correspondence position offers the space on the die drawing, and CH hole piercing punch mechanism wherein is installed.
Wherein, Said CH hole piercing punch mechanism comprises CH hole piercing punch, spring and cylinder assembly; CH hole piercing punch and draw between die the sliding guiding of joining; CH hole piercing punch is supported by spring, and CH hole piercing punch does not expose die shaping profile when guaranteeing not work, and CH hole piercing punch is driven by cylinder assembly during punching.
Further, cylinder assembly drives through the press source of the gas.
The invention also discloses and adopt above-mentioned producing device to make the method in automobile panel CH hole, comprise the steps:
1) towards drawn component, the press stroke is the not backhaul of back press top shoe on earth, draws punch and draw die to be kept closed;
2) drive the cylinder assembly in the piercing punch mechanism of CH hole through the source of the gas on the press, the CH hole piercing punch that cylinder assembly promotes in the piercing punch mechanism of CH hole is accomplished the making work of CH hole.
3) cylinder assembly backhaul, the piercing punch backhaul of CH hole, drawn component is taken out in last press top shoe backhaul.
Compare with conventional CH hole production method, the preparation method and the device thereof in this automobile panel CH hole have the following advantages:
During CH hole punching, draw the punch-die profile and still be in impaction state, the hole can not produce distortion during punching;
The drawn component second positioning problem that does not have conventional method, product CH hole location high conformity.
Description of drawings
View when Fig. 1 does not work for CH provided by the invention hole producing device;
View when Fig. 2 is the producing device work of CH provided by the invention hole.
Be labeled as among the figure:
1, draws die; 2, draw punch; 3, CH hole punching concave die; 4, CH hole piercing punch; 5, spring; 6, cylinder assembly; 7, drawn component.
The specific embodiment
Contrast accompanying drawing below; Through description to embodiment; Effect and operation principle, the manufacturing process of mutual alignment between the shape of specific embodiments of the invention such as related each member, structure, the each several part and annexation, each several part and manipulate method etc.; Do further detailed explanation, inventive concept of the present invention, technical scheme are had more complete, accurate and deep understanding to help those skilled in the art.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective; The high accuracy that is implemented in CH hole in the diel debug process is made; Thereby guarantee the goal of the invention of part accuracy, the technical scheme that the present invention takes comprises the steps:
As shown in Figure 1, offer bottom outlet on the punch 2 CH hole punching concave die 3 (also can directly on punch, offer bottom outlet as CH hole punching concave die) are installed drawing; Draw on the die 1 correspondence position and offer space mounting CH hole piercing punch mechanism.CH hole piercing punch mechanism comprises CH hole piercing punch 4, spring 5, cylinder assembly 6.CH hole piercing punch 4 and draw 1 cunning of die and join guiding, CH hole piercing punch 4 is being supported by spring 5 when not working, and guarantees that piercing punch 4 does not expose die shaping profile.CH hole piercing punch 4 is driven by cylinder assembly 6 and accomplishes punch work during punching, and cylinder assembly 6 drives through the press source of the gas.
As shown in Figure 2, after drawn component 7 draws completion, not backhaul of press slide, mould is kept closed, and this moment, the external source of the gas through press drove cylinder assembly 6, and cylinder assembly 6 promotes CH hole piercing punch 4 and moves downward, and accomplishes punch work; Backhaul is accomplished in cylinder assembly 6 exhausts; Piercing punch 4 backhauls of CH hole; The press slide backhaul; Take out drawn component 7.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
