Abstract
The utility model discloses a nitriding-free extrusion die for rare earth alloy aluminum profiles. The nitriding-free extrusion die comprises a female die and a male die which are matched with each other, wherein a welding cavity provided with a material extrusion hole is formed in the female die, the male die is provided with shunt holes and an extrusion head which is connected with the material extrusion hole, a wear-proof sleeve is added on the female die, and a boss is added on the male die, so that the wear resistance of the female die and the male die is strengthened. The wear-proof sleeve and the inner cavity wall of the female die are in key connection, a locating pin inserted in the boss is arranged on the extrusion head, mounting and dismounting are convenient, and the accuracy of products is high. When operators need to change sizes of the profiles slightly, all that is required is to change the inner diameter of the wear-proof sleeve and the outer diameter of the boss respectively instead of replacing the whole extrusion die, so that the working efficiency is greatly improved, and the cost is reduced. According to the extrusion die for the aluminum profiles, the wear-proof sleeve and the boss are added, so that 24-hour continuous work can be realized, and the output of the aluminum profiles is increased greatly.
Description
Technical field
The utility model relates to a kind of rare earth alloy extruding die for aluminum shaped material of exempting from nitriding.
Background technology
Extruding die for aluminum shaped material generally comprises die and punch, and in extrusion process, metal material constantly is pressed through from die and punch, and under the effect of high pressure friction, die surface easily weares and teares, and affects the quality of production of section bar.For this reason, people adopt the method that die surface is carried out to the nitriding carburizing to strengthen the hardness of mould.Although said method can strengthen the wear resistence of mould, need to consume the synthetic material of a large amount of nitrogenous, carbon compositions, also must coordinate special equipment, increased the input of cost.Carburized (case) depth generally only has 0.03mm～0.08mm, and a mold often carries out nitriding processing and needs only continuous operation 1～5 hour, needs dismounting carry out alkaline etching, polishing nitriding processing; Greatly improve the manufacturing cost of grinding tool by inlaying rare earth metal.An extruder is produced 24 hours, can not continuous operation, need to change extrusion die 5～25 covers and just can produce 1～5 ton of section bar, and every cover extrusion die is through after nitrogen treatment repeatedly, the deviate of the tolerance of extrusion die own increases thereupon, affects the quality of production of section bar.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of effective, Product Precision is high and cost is low rare earth alloy extruding die for aluminum shaped material of exempting from nitriding simple in structure, wear-resisting is provided.
Goal of the invention of the present utility model is achieved in that a kind of extruding die for aluminum shaped material, comprise the die and the punch that cooperatively interact, die is provided with the seam chamber with material extrusion hole, punch is provided with tap hole and the extrusion head be connected with material extrusion hole, it is characterized in that: in described material extrusion hole, be embedded with wear-resistant sleeve, described wear-resistant sleeve is that key is connected with the internal chamber wall of die, punch is provided with by clamp nut and is installed on the plush copper on extrusion head, plush copper is inserted the die cavity that forms section bar in wear-resistant sleeve, and described extrusion head is provided with the positioning pin column be inserted in plush copper.
Described wear-resistant sleeve is provided with the grinding set connecting key, and the internal chamber wall of die has the keyway matched with the grinding set connecting key.
The internal chamber wall of described die is provided with the key that is located by connecting, and has the keyway matched with the key that is located by connecting on wear-resistant sleeve.
The internal chamber wall of described die is provided with the spacing block set matched with wear-resistant sleeve.
Described wear-resistant sleeve and plush copper are alloy.
Described wear-resistant sleeve and plush copper are the carbide alloy that hardness is HRC68 ℃～HRC75 ℃.
The utility model is improved the extruding die for aluminum shaped material of prior art, sets up respectively wear-resistant sleeve and plush copper on die and punch, and wear-resistant sleeve and plush copper all adopt alloy material to make, and strengthens the wearability of die and punch.During this time, wear-resistant sleeve is that key is connected with the internal chamber wall of die, and extrusion head is provided with the positioning pin column be inserted in plush copper, has effectively guaranteed the accurate location of wear-resistant sleeve and plush copper, prevents from installing loosening, has greatly improved the accuracy of grinding tool.When operating personnel need to change amplitude when little to profile size, internal diameter and the external diameter that only need change respectively wear-resistant sleeve and plush copper get final product, do not need to change a whole set of extrusion die, have greatly improved operating efficiency and have reduced costs.Extruding die for aluminum shaped material of the present utility model, by increasing wear-resistant sleeve and plush copper, can realize 24 continuous throughout the twenty-four hour24s, greatly improved the output of aluminium section bar.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
Shown in 1 to Fig. 5, extruding die for aluminum shaped material of the present utility model, comprise the die 1 and the punch 2 that cooperatively interact with reference to the accompanying drawings.Die 1 end face is provided with the seam chamber 3 to lower recess, and the seam chamber has material extrusion hole 4 on 3 centers, and this material extrusion hole 4 is for running through the through hole of die; Punch 2 is provided with tap hole 5 and the extrusion head 6 be connected with material extrusion hole 4.Be embedded with wear-resistant sleeve 7 in material extrusion hole 4, this wear-resistant sleeve 7 and material extrusion hole 4 position adaptations, during this time, wear-resistant sleeve 7 is that key connects with the internal chamber wall of die 1, location and installation is on the internal chamber wall of die 1 accurately to make wear-resistant sleeve 7, and specifically, this key connected mode can be two kinds of following versions: (1), wear-resistant sleeve 7 are provided with grinding set connecting key 12, the internal chamber wall of die 1 has the keyway matched with grinding set connecting key 12, as shown in Figure 2; (2), the internal chamber wall of die 1 is provided with the key 13 that is located by connecting, and has the keyway matched with the key 13 that is located by connecting on wear-resistant sleeve 7, as shown in Figure 3.
Simultaneously, punch 2 described in the utility model is provided with plush copper 8, and this plush copper 8 is installed on extrusion head 6 by clamp nut 9, and this clamp nut 9 runs through plush copper 8 and is connected with extrusion head 6, prevents that deviation from appearring in loosening the causing of plush copper 8.Plush copper 8 is inserted in wear-resistant sleeve 7, difference in size between the internal diameter of the external diameter of plush copper 8 and wear-resistant sleeve 7 forms the thickness of section bar, be the die cavity 10 of section bar, size changes according to user's needs, extrusion head 6 is provided with the positioning pin column 11 be inserted in plush copper 8, can make the accurate location and installation of plush copper 8 energy on extrusion head 6, be conducive to improve the accuracy of grinding tool.
