Description
Technical field
A kind of double internal lock moulds for thin plate impressing connection are the utility model is related to, belong to mold design technical field.
Background technology
With aviation and the continuous development of auto manufacturing, the application of lightweight structure and new lightweight material is increasingly extensive.
It is at most the sheet materials such as Al alloys andMg alloys to be applied in aviation and automobile manufacturing field, and existing sheet material connection method includes welding, spiral shell
Tether and connect and rivet, but because the chemically or physically performance of these sheet materials causes welding performance bad or can not weld, bolt
Connection and riveting etc. need to punch in advance, complex process, poor sealing performance, also need using additional tie members such as bolt and rivet etc..
And it is a new technology for being applied to sheet material connection to imprint connection.It is real to sheet material under external force by imprinting connecting mold
Cold-pressing deformation is applied, forces connected combination of materials generating material at tie point to flow, phase is formed by metal plastic deformation
The tie point mutually inlayed realize material connect.But current impressing connection is all single internal lock tie point, after sheet material connection often
Bonding strength deficiency or bad some problems of grade of shaping are had, and in the case of some sheet material bonding strength demands are larger,
Need repeatedly to connect sheet material using single internal lock impressing tie point, not only process is cumbersome, and efficiency is low.Therefore, need
Develop a kind of double internal lock impressing moulds for thin plate impressing connection.
The content of the invention
For the above-mentioned problems of the prior art and deficiency, the utility model provides a kind of thin plate that is used for and imprints connection
Double internal lock moulds.This pair of internal lock mould bonding strength is bigger, more reliable, simple to operate, environmental protection and economy, is readily formed and has been easy to
Mould.The utility model is achieved through the following technical solutions.
A kind of double internal lock moulds for thin plate impressing connection, including drift and the lower mould with drift cooperation, the lower mould
Including circular bosses from the inside to the outside, inner circle annulated column and cylindrical annulated column, the ram bottom is provided with cylindrical hole, circular bosses and interior annular
Inner groovy is formed between post, external groove is formed between inner circle annulated column and cylindrical annulated column.
The circular bosses carry 0.5 °~2 ° pattern drafts.
Operation principle of the present utility model is：As shown in figure 3, two boards are placed on lower mould, when drift is with cylindrical hole
When beginning to decline, less elastic-plastic deformation takes place in upper and lower two plate, when drift goes downwards to certain distance, due to upper
The extruding lower plate of plate continues deformation downwards, and as drift continues to decline, sheet material starts to fill lower mould space and mould inner ring is recessed downwards
Groove and the interior flowing of outer ring groove, and the mechanical interlocked structure with certain amount of inlaying is formed, and then formation has Internal and external cycle
Double internal locks impressing attachment structure of two layers of internal lock.
The beneficial effects of the utility model are：
1st, the utility model imprints attachment structure using double internal locks, and the impressing compared to existing single internal lock connects, double internal locks
Intensity height, the connection for imprinting tie point are reliable.
2nd, the drift designed by the utility model and lower mould are designed with necessary excessive fillet, and lower mould central boss is pulled out
Mould gradient, reduce the abrasion of mould and be easily attached the molding of rear sheet material.
3rd, the lower mould designed by the utility model has Internal and external cycle groove, and the effect of groove increases internal modification space, had
Beneficial to sheet material forming.
4th, the connection that the utility model can be used between metal, nonmetallic, unlike material sheet metal etc..
