Description
Technical field
The utility model is related to mechanical technical field of forging, and in particular to a kind of automobile intake and exhaust flange.
Background technology
Every union piece closed simultaneously using bolt connection in two planar perimeters, typically referred to as " flange ", often
What is seen is the connection between pipeline and pipeline, connection between equipment and equipment etc., and flange has great practicality.Have on flange
Eyelet, perforation could be completed to install, and thin-wall flange can be realized by drilling, punching press.And thick wall flange, especially punching are thick
Degree is far longer than punching hole diameter, and low using drilling machine drilling efficiency, centre-to-centre spacing often changes, and precision cannot ensure；Use punch press
Punching, drift is often broken, and efficiency is low, wastes huge.So how to ensure that punching precision is indeformable, punch center is away from constant
High efficiency is realized just being particularly important in the case of change.
Automobile intake and exhaust flange is realized by this mode of cold punching more as the representative of shaped piece product.Because
Automobile intake and exhaust flange shape is irregular, and mesopore is big, and waste material wastes serious, and stock utilization is low, causes cold drawing production cost one
It can be in any more directly, and the product plane of disruption is irregular, unsightly, lacks industry competition.
The product in many fields is imperative to realize using this mode is forged, and more than 80% product can be with holding in industry
Formula mould this mode realizes that open die is that raw material are put into die cavity, extrudes slitter edge, is then sliced out slitter edge, obtains desired
Shape, such stock utilization is improved not substantially, and product edge density is unstable, and working environment is very poor, is not perfect forging
Make the mode of production.
Utility model content
The purpose of this utility model is to provide a kind of automobile intake and exhaust flange, the length of mounting hole and the aperture ratio of mounting hole
It is 1.3-1.5:1, the flange is thick flange, and the intensity of flange is effectively ensured.
To achieve the above object, the technical scheme that the utility model is used is：The flange includes body, is set on body
There is mesopore, mesopore is provided with mounting hole, and the length of mounting hole is 1.3-1.5 with the aperture ratio of mounting hole:1.
Preferably, the quantity of the mounting hole is two, and mounting hole is respectively positioned at the both sides of mesopore.
Preferably, the flange is formed by closed mould forging.
Preferably, the mounting hole is stamped to form by hydraulic press.
Preferably, the hydraulic press is provided with buffer unit, and the operating pressure of the hydraulic press is 180-220T, described slow
The cushion effect of flushing device is 8-12T, and the drift on hydraulic press is 140-160mm/s to the drawing velocity of mounting hole.
After adopting the above technical scheme, the utility model has the positive effect that：
(1) flange in the utility model is thick flange, and the intensity of flange has been effectively ensured, and automobile is forged using closed mould
Easily there is slitter edge, lacks material, cracking, intensity shakiness in solving the forging of automobile intake and exhaust flange in the preparation technology of intake and exhaust flange
The problems such as determining, the forging method of traditional open die has very big to the ambient intensity of finished product flange periphery slitter edge, cracking and flange
Influence, easily produces cracking phenomena；The present invention uses process of the round bar shape material by closed mould, directly in forming cavity
Punching press is obtained, and for the forging of flange especially thick flange, is greatly improved the utilization rate problem of product quality and raw material,
The utilization rate of material is reached more than 80%, improve product quality, beautified product appearance, save production cost, make product
Product are more competitive；
(2) closed mould forging compared with open-die forging flange, cuts off the operation of slitter edge together less in the utility model, from
And operating efficiency is greatly improved, class's yield is up to 5500, and open-die forging automobile intake and exhaust flange at most can only achieve
3000, class's yield improves 83.3%, improves operating efficiency；
(3) present invention carries out the punching of thick wall flange mounting hole using hydraulic press, straight much larger than punching for punching thickness
The situation in footpath, it is ensured that punching precision is indeformable, punch center, while ensureing that drift is not easy to break, uses biography away from not changing
The drilling machine or punch press efficiency of system are low, waste big, and the present invention is 1.3-1.5 with the aperture ratio of mounting hole for the length of mounting hole:1
Thick wall flange, can accurately go out mounting hole, solve use drilling machine drill or punch press punched-tape come defect.
