Description

Aluminum product extrusion device

Technical Field

The invention relates to the technical field of nonferrous metal processing, in particular to an aluminum material extrusion device.

Background

A special nitrogen blocking tool is not arranged at a discharge port of the press, and a product is extruded out and is in direct contact with air, so that the product is particularly easy to react and oxidize with the air, and the quality of the product is influenced by generation of rough particles on the surface of the section. The produced hair particles are not easy to drop, and the surfaces of the products are easy to scratch in the processes of carrying, packaging and transporting the products, so that the use of customers for the products is influenced. The contact of the product with air is reduced, and the reaction time with the air is prolonged, therefore, an aluminum material extruding device is provided to solve the problems.

Disclosure of Invention

The invention aims to provide an aluminum material extruding device, which aims to solve the problems that a special nitrogen blocking tool is not arranged at a discharge port of a press in the background technology, a product is directly contacted with air after being extruded out, the product is particularly easy to react and oxidize with the air, and the quality of the product is influenced by the generation of rough particles on the surface of a section. The produced hair particles are not easy to fall off.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides an aluminum product extrusion device, includes die cavity, extrusion section bar and mould, the standing groove has been seted up to one side of die cavity, install the mould in the standing groove, the die cavity hole has been seted up to the inside of die cavity, and the output of mould is connected with the extrusion section bar, and the extrusion section bar extends to in the die cavity hole.

Preferably, one side of the die cavity, which is far away from the die, is provided with a nitrogen blocking tool, one side of the nitrogen blocking tool, which is attached to the die cavity, is provided with a through groove, and the extruded section bar passes through the through groove.

Preferably, a cattle rib plate is arranged on one surface of the nitrogen blocking tool, which is in contact with the wallboard, and the thickness of the cattle rib plate is 2-3 mm.

Preferably, the placing groove is provided with irregular anti-skid lines.

Compared with the prior art, the invention has the beneficial effects that: according to the invention, a closed space can be formed between the discharging port and the die, then the nitrogen pipe is inserted into the closed space, and the whole space is filled with nitrogen to form a nitrogen cavity, so that the contact time of the section bar and air is delayed, the surface quality is improved, the tool is convenient to install and use, the production efficiency can be improved by the nitrogen blocking tool, and the production quality of the surface of a product can be ensured.

FIG. 1 is a first perspective view of the present invention;

FIG. 2 is a second perspective view of the present invention;

fig. 3 is an exploded view of the structure of the present invention.

In the figure: 1. a mold cavity; 2. extruding the profile; 3. a mold; 4. a nitrogen blocking tool; 5. a cavity bore; 6. a through groove; 7. and (6) placing the groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, an embodiment of the present invention is shown:

the utility model provides an aluminum product extrusion device, includes die cavity 1, extrusion section bar 2 and mould 3, and standing groove 7 has been seted up to one side of die cavity 1, installs mould 3 in the standing groove 7, is provided with the anti-skidding line of irregular form on the standing groove 7, and the anti-skidding line that sets up on the standing groove 7 can avoid mould 3 to rock, has further promoted the practicality of device.

Die cavity hole 5 has been seted up to die cavity 1's inside, and the output of mould 3 is connected with extrusion section bar 2, and extrusion section bar 2 extends to in the die cavity hole 5, die cavity 1 is kept away from one side of mould 3 and is installed stifled nitrogen gas frock 4, one side of stifled nitrogen gas frock 4 laminating each other all sets up and leads to groove 6, extrusion section bar 2 passes logical groove 6, the one side of stifled nitrogen gas frock 4 and wallboard contact is provided with the ox gusset, and the thickness of ox gusset is 2-3mm, the one side of stifled nitrogen gas frock 4 and wallboard contact has the thick ox gusset of 2-3mm, can let form an inclosed space between discharge gate 5 and the mould like this, then inject the nitrogen gas pipe in the airtight space, let be full of nitrogen gas formation nitrogen gas chamber in the whole space, thereby delay the time improvement surface quality of section bar and air contact.

The working principle is as follows: according to the shape of the discharge port 5 of the press and the shape of the extruded section bar 2, the nitrogen blocking tool 4 is made of a steel plate or an aluminum plate, namely two baffles are arranged one above the other, the baffles can be manufactured according to the shape of a product, and handles can be welded on the baffles, so that the baffles are convenient to install and disassemble. According to the shape of stifled nitrogen gas frock 4 punching the tapping in advance on 1 wallboard of die cavity, during the installation, earlier pass through the screw tightening with lower baffle and install in discharge gate 5 below, the discharge gate 5 is pull out to the aluminium alloy, then passes through the screw tightening installation with last baffle again and fixes. One side of the nitrogen blocking tool 4, which is in contact with the wall plate, is provided with a tendon plate with the thickness of 2-3mm, so that a closed space can be formed between the discharge port 5 and the die 3, then a nitrogen pipe is inserted into the closed space, and the whole space is filled with nitrogen to form a nitrogen cavity, so that the contact time of the section bar and air is delayed, and the surface quality is improved.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
