Description

Continuous bridge-spanning long-section aluminum profile die

Technical Field

The utility model relates to an aluminium alloy mould especially relates to a bridge long section aluminium alloy mould strides in succession.

Background

Generally, an aluminum profile is obtained by extruding an aluminum alloy material through an aluminum profile die on an extruder. The existing aluminum profile die comprises an upper die and a lower die, wherein the upper die is provided with a feeding port, and the lower die is provided with a discharging port. As shown in figure 1, the aluminum profile with the long section span has a long cross section, and a suspended wall with a long span and a high height is required to be arranged on a lower die for forming, and the suspended wall is easy to deform under the impact of a metal material, so that the size of a discharge port of the lower die is unstable, the thickness of a rib 1A at the middle part is uneven, and the yield of a product is low.

Disclosure of Invention

An object of the utility model is to provide an accurate long section aluminium alloy mould of striding bridge in succession of size.

In order to achieve the above object, the technical solution of the present invention is:

the utility model relates to a continuous bridge-spanning long-section aluminum profile die, which comprises a guide plate, an upper die and a lower die; the guide plate, the upper die and the lower die are sequentially overlapped together; the top surface of the blocking rib of the upper die is opposite to the middle part of the discharge port of the guide plate guide groove, and the bottom surface of the blocking rib of the upper die is opposite to the middle part of the feed port of the lower die discharge groove.

The guide plate is provided with four guide grooves which are arranged in a matrix; the upper die is provided with six feeding grooves which are arranged in a matrix manner, three feeding grooves are arranged in a longitudinal row, two feeding grooves are arranged in a transverse row, and two blocking ribs are formed between two adjacent feeding grooves in the three feeding grooves in the longitudinal row; the middle part of the lower die is provided with a discharge chute, and a feed inlet of the discharge chute is provided with two suspension walls; the top surfaces of the two blocking ribs on the adjacent feeding grooves of the upper die are opposite to the middle parts of the discharge holes of the two guide grooves on the guide plate respectively, and the bottom surfaces of the two blocking ribs on the adjacent feeding grooves of the upper die are opposite to the middle parts of the two cantilever walls at the discharge holes of the discharge groove on the lower die respectively.

The aperture of the four diversion trenches of the diversion plate is gradually enlarged from the feeding port to the discharging port, and the four feeding trenches on two sides of the width direction in the upper die are gradually enlarged from the feeding port to the discharging port.

After the scheme is adopted, because the utility model comprises the guide plate, the upper die and the lower die, the top surface of the blocking rib of the upper die is opposite to the middle part of the discharge port of the guide plate guide groove, the bottom surface of the blocking rib of the upper die is opposite to the middle part of the feed port of the lower die discharge groove, and during extrusion, the blocking rib of the upper die well slows down the impact of a metal material on the overhanging wall of the feed port of the lower die discharge groove, thereby ensuring the stable size of the discharge port of the lower die and the accurate and consistent wall thickness of the produced aluminum profile; in addition, owing to be equipped with the guide plate, the baffle box on the guide plate and the inclination of last feed chute of mould are gentler for metal material more easily with abundant flow direction both sides on the width of lower mould, more be favorable to producing long sectional aluminium alloy.

The invention will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description

As shown in fig. 2-6, the utility model relates to a long section aluminium alloy mould strides bridge in succession, including guide plate 1, last mould 2, lower mould 3.

The guide plate 1, the upper die 2 and the lower die 3 are sequentially overlapped together; the top surface of the blocking rib 21 of the upper die 2 is opposite to the middle part of the discharge hole of the guide groove 11 of the guide plate 1, and the bottom surface of the blocking rib 21 of the upper die 2 is opposite to the middle part of the feed hole of the discharge groove 31 of the lower die 3.

In this embodiment, the guide plate 1 is provided with four guide grooves 11, and the four guide grooves 11 are arranged in a matrix; the upper die 2 is provided with six feeding grooves 22, the six feeding grooves 22 are arranged in a matrix manner, three feeding grooves 22 in a longitudinal row and two feeding grooves 22 in a transverse row form two blocking ribs 21 between two adjacent feeding grooves in the three feeding grooves 22 in the longitudinal row, and what needs to be described is that: the blocking ribs 21 on the three feed chutes 22 arranged in one side column are not required. The middle part of the lower die 3 is provided with a discharge chute 31, and a feed inlet of the discharge chute 31 is provided with two suspension walls 32; the top surfaces of the two blocking ribs 21 on the adjacent feeding grooves 22 of the upper die 2 are opposite to the middle parts of the discharge holes of the two guide grooves 11 on the guide plate 1 respectively, and the bottom surfaces of the two blocking ribs 21 on the adjacent feeding grooves 22 of the upper die 2 are opposite to the middle parts of the two hanging walls 32 at the discharge hole 31 on the lower die 3 respectively.

The aperture of four guiding gutters 11 of guide plate 1 enlarges gradually from the pan feeding mouth toward discharge gate direction Y, goes up four feed chute 22 of width direction both sides and enlarges gradually from the pan feeding mouth toward discharge gate Y direction in mould 2, through setting up guide plate 1 and last mould 2, increases the thickness of pan feeding direction to the inclination that makes the flaring is gentler, in order to do benefit to the both sides supply of metal material on to the width X of lower mould 3, more is favorable to producing long sectional aluminium alloy.

The utility model discloses a theory of operation:

two blocking ribs 21 on the adjacent feeding grooves 22 of the upper die 2 well slow down the impact of metal materials on the suspended wall 32 at the feeding hole of the discharging groove 31 of the lower die 3, and the stability of the size of the discharging hole of the lower die is ensured.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
