Problems solved by technology

[0003] The hot extrusion die of aluminum alloy profiles generally includes a punch, a die and a core. Firstly, the core is fixed between the punch and the die with bolts, and then the punch and the die are fixedly connected to complete the process. Assembling the mold, most of the current punches and dies use high-strength bolts to fix the two, but the fastness is average, and it is easy to loosen after a period of use, which affects the processing quality of the profile. In order to solve the above problems, this application proposes a A kind of aluminum alloy hot extrusion die and its assembly method can improve the fastening between concave and convex dies

Embodiment 1

[0035] Such as Figure 1-7 As shown, an aluminum alloy hot extrusion die proposed by the present invention includes a disc-shaped punch 101, a core 201 and a die 301, and also includes two fastening bolts 203 and two hexagonal bolt mechanisms, The fastening bolts 203 are hexagon socket bolts, and the middle part of the punch 101 is fixedly provided with an entrance sinker 102 for entering the heated profile, and several diversion holes 103 are horizontally penetrated on the entrance sinker 102 to facilitate the diversion of the metal flow. The side of the 102 away from the die 301 is fixedly provided with an entrance milling sinker 106, and two fastening screw holes 104 are provided on the side wall of the entrance sinker bridge 102;

[0036] In this embodiment, there are two mounting holes 202 horizontally penetrating through the mold core 201, and the two fastening bolts 203 pass through the mounting holes 202 and are screwed into the fastening screw holes 104 for fixing the...

Embodiment 2

[0041] This embodiment provides a method for assembling an aluminum alloy hot extrusion die, comprising the following steps:

[0042](1) Assembling the mold core: place the punch 101 horizontally with the side with the fastening screw hole 104 facing up, place the mold core 201 in the middle of the horizontal punch 101, and put the two fastening bolts 203 into the mold respectively. In the mounting hole 202 on the core 201, the bottoms of the two fastening bolts 203 all pass through the mounting holes 202 and touch the punch 101 at this time, and when the core 201 is rotated, the bottoms of the fastening bolts 203 are rotated to the fastening screw holes 104 When stop, turn fastening bolt 203 and mold core 201 is fixed on the punch 101;

[0043] (2) Mold closing: erect the punch 101 with the mold core 201 erected, respectively insert two hexagonal bolts 401 through the hexagonal groove 502 and the long groove 501 on the punch 101, at this time the outer hexagonal bolt 401 and ...

Abstract

The invention belongs to the technical field of moulds, and in particular relates to an aluminum alloy hot extrusion die and an assembly method thereof, including a punch, a core and a die, and two fastening bolts and two outer hexagonal bolt mechanisms. The middle part of the punch is fixedly equipped with an entrance sinker bridge, and several flow holes are horizontally penetrated on the entrance sinker bridge, and two fastening screw holes are opened on the side wall of the entrance sinker bridge; two mounting holes, and the two fastening bolts pass through the mounting holes and are threaded into the fastening screw holes; when the die and the punch are matched in the present invention, the first nut and the second nut are used to achieve double Fastening effect, the tightness between the punch and the die is stronger, and the service life of the die is longer; through the cooperation design of the ball, the rolling groove and the limit groove, the punch and the die are aligned when the punch and the die are closed. It is pre-positioned, and the holes are more convenient and accurate when the two are fastened, and the assembly is more labor-saving. The invention has a simple structure, an ingenious design, and is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of dies, in particular to an aluminum alloy hot extrusion die and an assembly method thereof. Background technique [0002] Hot extrusion is to heat the metal material to the hot forging forming temperature for extrusion, that is, to heat the billet to a temperature above the recrystallization temperature of the metal before extrusion. Hot extrusion can not only form non-ferrous metals and their alloys with good plasticity and relatively low strength, low and medium carbon steels, etc., but also form high carbon and high alloy steels with high strength, such as special structural, stainless steel, high-speed Tool steel and heat-resistant steel, etc. Since the billet must be heated to the hot forging temperature for extrusion. In general, after machine parts are hot-extruded, machining such as cutting is used to improve the dimensional accuracy and surface quality of the parts. [0003] The hot extrusion d...
