Description

Moulding face different coefficients of friction and controllable forming method
Technical field
The invention belongs to stamping drawdown parts forming field, it is related to a kind of moulding face different coefficients of friction and controllable side Method, can be applied in institute's stamping drawdown forming process in need, to improve or reach molding effect.
Background technology
In sheet metal component forming field, shaping of extending is a widely used mode, and the difficult point for shaping of extending is material Various corrugations that unstability into space curved surface flow process is caused and rupture, particularly aluminium sheet and high-strength plate into V-neck V Domain, and improve controllable in material flow process of the emphasis of flow unstable and stably, coefficient of friction is used as material flow process In an important factor, have impact on final part result.And common moulding face is a coefficient of friction, it is impossible to adjust. Easily cause manufacture difficulty or shaping failure.
The content of the invention
The invention aims to solve the technical problem of above-mentioned prior art, this method is to provide different friction systems Count to control the flow direction property and speed of material, to reach the expected purpose of shaping.Have a good application prospect.
The present invention concrete technical scheme be:
A kind of moulding face different coefficients of friction and controllable forming method, include mold body, lower mold, pressure rings, rub Wipe coefficient block and controllable pressure source or fixed adjust pad;The corresponding required portion on moulding face pressure material ring or mold body Position sets different coefficient of friction blocks respectively;In required flowing fast position, low-friction coefficient block is set, slow in required flowing Position sets great friction coefficient block.
Further, the low-friction coefficient block is mirror finish block.
Further, the coefficient of friction block or fixed adjust pad are to adjust pressure according to controllable pressure source, and then The coefficient of friction changed, realizes that each position obtains different suitable coefficient of friction, so as to distinguish the flowing of control material Stable and controllability, improves or solves difficult locally-shaped destabilization problems.
This method is not limited to stamping drawdown mould applications, can be extended to have product or part in production and manufacture and wants In other moulds asked.
Brief description of the drawings
Fig. 1 is the structural representation of coefficient of friction block in a mold.
Fig. 2 is the coefficient of friction block of mirror finish block structure.
Fig. 3 is a kind of coefficient of friction block pattern.
Fig. 4 is another coefficient of friction block pattern.

In figure:1. mold body;2. lower mold;3. pressure rings;4. the first coefficient of friction block;5. fixed adjust Whole pad;6. the second coefficient of friction block;7. controllable pressure source.
Embodiment
The principle that the invention will now be described in detail with reference to the accompanying drawings, for clearly illustrating technical scheme.
Exemplified by Fig. 1, this forming method includes mold body 1, lower mold 2, pressure rings 3, the first coefficient of friction block 4, the second coefficient of friction block 6 and controllable pressure source 7 or fixed adjust pad 5;On moulding face pressure material ring or mold body Corresponding required position sets different coefficient of friction blocks respectively;In required flowing fast position, low-friction coefficient block or mirror are set Mirror polish block, as shown in Figure 2;Great friction coefficient block is set in required flowing slow position, as shown in Figure 3 and Figure 4.
The coefficient of friction block or fixed adjust pad are foundation controllable pressure source adjustment pressure, and then changed Coefficient of friction, realizes that each position obtains different suitable coefficient of friction, so that the flowing for distinguishing control material is stable and controllable Property, improve or solve difficult locally-shaped destabilization problems.
As shown in figure 1, needing material comparatively fast to flow at A, material is needed at B compared with slow flow.Then it is corresponding in binder ring or Set on mold body at A and great friction coefficient block is set at low-friction coefficient block, B.Each position of difference control, which is realized, to be needed Coefficient of friction, as shown in figure 5, Schema Theory software conclusion is derived from Autofrm R3.1, before the inventive method, material stream Dynamic 19.65mm;After applying the present inventive method, material flowing 11.34mm, reaches ideal effect.
