Description
Technical Field
The utility model relates to an extrusion die, in particular to suspension bridge formula aluminium alloy extrusion die.
Background
The cantilever aluminum profile product is a profile product forming a semi-closed shape. The die in which the product is processed forms a loaded cantilever during extrusion. Because the die is in a state of high-temperature high-pressure intermittent load in the extrusion process, if the die is improperly designed, the cantilever part of the die is easily deformed or broken, and the service life of the die is directly influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to the above-mentioned defect among the prior art, provide a suspension bridge formula aluminium alloy extrusion die, can avoid the cantilever fracture or sink, improve mould life.
In order to realize the purpose of the utility model, the utility model adopts the following technical scheme: the utility model provides a suspension bridge formula aluminium alloy extrusion die, its includes the water conservancy diversion mould and the section mould of mutually supporting, the water conservancy diversion mould is including reposition of redundant personnel bridge and connection the core head of reposition of redundant personnel bottom of the bridge portion, the section mould includes the cantilever of seam room and shaping section bar cantilever portion, the cantilever is located the core head lower extreme, be equipped with the suspension bridge on the seam room, suspension bridge one end with the seam room is fixed mutually, the other end with the cantilever is connected.
Furthermore, the utility model discloses still provide following subsidiary technical scheme: the shunt bridge is in a straight line shape.
The flow guide die comprises two flow distribution holes which are divided by the flow distribution bridge and communicated with the welding chamber.
The outer contour of the core print is the same as the shape of the cantilever.
Compared with the prior art, the utility model has the advantages of: the extrusion die of the utility model is provided with the core print corresponding to the cantilever on the shunting bridge, and the core print can greatly reduce the stress of the cantilever; in addition, the suspension bridge arranged on the welding chamber can reinforce the cantilever structure, and the cantilever is prevented from being broken or collapsed.

Fig. 3 is a schematic view of the structure of an extruded profile.
Detailed Description
The following non-limiting detailed description of the present invention is provided in connection with the preferred embodiments and accompanying drawings.
As shown in fig. 1 to 3, a suspension bridge type aluminum profile extrusion die corresponding to a preferred embodiment of the present invention includes a guide die 1 and a forming die 2, wherein the guide die 1 and the forming die 2 are stacked front and back and are connected into a whole through a pin.
Further, the guide die 1 comprises a straight-line-shaped diversion bridge 11 and two diversion holes 12 divided by the diversion bridge 11, and the bottom of the diversion bridge 11 is connected with the core head 4.
The section die 2 comprises a welding chamber 21 and a die hole (not shown) located below the welding chamber 21, the die hole is in a semi-closed shape matched with the shape of the section bar 3, a cantilever 22 is arranged in the die hole, the cantilever 22 is used for forming a cantilever part 31 of the section bar 3, the cantilever 22 is located at the lower end of the core head 4, the outline of the core head 4 is the same as the shape of the cantilever 22, the stress of the cantilever 22 can be greatly reduced by the core head 4, the situation that the cantilever 22 is broken is avoided, and the service life of the die is prolonged.
In addition, a suspension bridge 23 is arranged on the welding chamber 21, one end of the suspension bridge 23 is fixed with the welding chamber 21, and the other end is connected with the feeding end of the cantilever 22. By adding the suspension bridge 23 at the feeding end of the cantilever 22, the top end of the cantilever 22 fixes the suspension bridge and the welding chamber 21 together, so that the effect of reinforcing the structure of the cantilever 22 is achieved, and the cantilever 22 is not worried about deformation or collapse; simultaneously, compare and piece together the mouth formula or tear the mould of skin formula and improve cantilever 22 intensity, piece together the mouth formula or tear the skin formula and exist crowded mouthful department or tear the skin and be in the problem that has the burr in the section bar after the extrusion, adopt the design of bridge type design reinforcing cantilever 22 intensity, section bar cantilever department can not have the burr.
The utility model discloses extrusion die is when using, and the aluminium material gets into seam room 21 through the reposition of redundant personnel back of water conservancy diversion mould 1, and the required section bar 3 is become through the nib shaping to the metal flow. The static pressure originally born by the cantilever 22 is transferred to the guide mould 1 in the extrusion process, so that the stress of the cantilever 22 in the mould 2 is reduced, and the situation that the cantilever 22 is broken is avoided; when the guide die 1 bears the metal static pressure, the guide die 1 can sink and deform, so that a working gap is formed between the core print 4 and the cantilever 22, and the cantilever 22 cannot be stressed directly when the guide die 1 sinks and deforms. In addition, the suspension bridge design is adopted at the feeding end of the cantilever 22, so that the strength of the cantilever is enhanced, and deflection, collapse or fracture at the cantilever 22 is avoided.
It should be noted that the above-mentioned preferred embodiments are only for illustrating the technical concepts and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention accordingly, and the protection scope of the present invention cannot be limited thereby. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
