Description
Technical field
Mould design and manufacture technical field is the utility model is related to, more particularly to a kind of precision stamping of deep hole class product
Mould.
Background technology
Stamping die, is one kind by metal or process for un-metal material into part or semi-finished product in Cold Press Working
Special process is equipped, and is known as cold punching die, is commonly called as cold-punching mould.Punching press, is at room temperature, to utilize rushing on forcing press
Compression mould applies pressure to material, it is produced separation or plastic deformation, so that a kind of pressure processing side of part needed for obtaining
Method.
Compared to more typical punching or bending process, the punching press of product is often more complicated, it is necessary to carry out progressively in deep hole
Decompose, the deflection of control single stretching, prevents product from pulling damage.Thus, require it is not stringent in the case of, on product
Deep hole can be attached setting by the way of welding, however, the stress intensity of its deep hole is not high.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided a kind of precise punching mould of deep hole class product
Tool, improves intensity of the deep hole in product entirety, while improves stamping procedure, the product quality of lifting workpieces.
In order to achieve the above object, the technical solution adopted in the utility model is：A kind of precision stamping of deep hole class product
Mould, includes upper mold seat, upper padding plate, upper clamp plate, baffle plate, stripper plate, lower template, lower bolster and the die holder of order installation,
Punching pin and punch-pin are installed, punching pin group includes punching punching pin, stretching punching pin group and shaping punching pin group, stretching punching on the upper clamp plate
The head section of subgroup is semicircle, and the head rectangular cross-section of shaping punching pin group, punch-pin includes overlap punch-pin, the overlap punch-pin
On be machined with the protrusion of limiting displacement, plate is placed between stripper plate and lower template.
Further, the shape of overlap punch-pin as described above is concave arc.
Further, the head of stretching punching pin group is cambered surface transition as described above, and the quantity of stretching punching pin group is at least
Three.
Further, first punching pin head is rounding angular shape in shaping punching pin group as described above.
Further, the quantity of shaping punching pin group as described above is at least three.
Compared with prior art, the beneficial effects of the utility model are：The present apparatus is set by the concave arc of overlap punch-pin
Meter so that the deep hole stretcher strain amount on plate is easily controllable, while using stretching punching pin group and shaping punching pin group, gradually realizes
Deep blind hole processing in workpiece, process is simple, and compared to blind hole is welded to connect, the intensity higher of blind hole, the Quality advance of workpiece, gives birth to
Production efficiency also improves.

Embodiment
Be described in detail referring to the drawings with reference to embodiment, so as to the technical characteristics of the utility model and advantage into
Row deeper into annotation.
As shown in figures 1-8, the precise punching die of a kind of deep hole class product of the utility model, including order installation are upper
Die holder, upper padding plate, upper clamp plate, baffle plate, stripper plate, lower template, lower bolster and die holder, install punching pin on the upper clamp plate
And punch-pin, punching pin group include punching punching pin 2, stretching punching pin group 7 and shaping punching pin group 9, the head section of stretching punching pin group 7 is half
Circle, adapts to the deep hole of workpiece 4, the head rectangular cross-section of shaping punching pin group 9, and punch-pin includes overlap punch-pin 3, overlap punch-pin 3
Shape be concave arc so that the deep hole stretcher strain amount on plate 1 is easily controllable, is processed on the overlap punch-pin 3 restricted
The protrusion 8 of displacement, places plate 1 between stripper plate and lower template；The head of the stretching punching pin group 7 is cambered surface transition,
Stretch the transition of punching pin group 7 and shaping punching pin group 9, the quantity of stretching punching pin group 7 is at least three, the in shaping punching pin group 9
One punching pin head is rounding angular shape, and the quantity of shaping punching pin group 9 is at least three.
The workpiece 4 of present apparatus processing is as shown in figure 4, there is 6 two holes of the first cavity 5 and the second cavity on workpiece 4, wherein the
One cavity, 5 depth is small, and common punching press can be achieved, the depth of the second cavity 6 be then more than its diameter, it is necessary to carry out repeatedly load-unload and
Shaping, is a kind of embodiment if Fig. 2-4, is divided into five drawing and five shapings, and each deep-drawing deformation amount then controls
Within 4 material single Limit Drawing deflection of workpiece, in order to avoid plate 1 is pulled open, 4 mass of workpiece is influenced.The welding that compares connects
Deep hole is connect to workpiece 4, welding sequence it is complicated, batch quality is difficult to control, and the intensity of product is low, and the present apparatus is then plate
1 continuous punch forming of material, after the completion of debugging production, production efficiency is high, batch stable quality, and product quality intensity is high.
Clear, complete description carries out the utility model by the technical solution in above example, it is clear that described
Embodiment be the utility model part embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, those of ordinary skill in the art's all other embodiments obtained without making creative work, belongs to
The scope of the utility model protection.
