Description

Technical Field

[0001] This utility model relates to the field of extrusion molding machines, specifically a high beryllium aluminum alloy extrusion molding machine. Background Technology

[0002] An aluminum profile extrusion press is a crucial piece of equipment in the production of aluminum and its alloy profiles. It mainly consists of mechanical, hydraulic, and electrical components. The mechanical components include a base, guide columns, crossbeams, insulation seats, scissor seats, and die seats. The hydraulic system comprises a main cylinder, auxiliary cylinder, locking cylinder, die seat cylinder, piston pump, and vane pump. The electrical components include a power supply cabinet, operating console, and PLC programmable controller. Existing aluminum profile extrusion presses can only perform straight extrusion, requiring the extruded inner wall to be straight. This type of aluminum profile has poor lateral stress resistance, especially in cases where column-type aluminum profiles require specific lateral stress resistance, necessitating the use of steel plate columns, thus limiting the application of this type of aluminum profile.

[0003] To address the aforementioned issues, a search revealed Chinese Patent CN222902189U, which discloses an aluminum profile extrusion press. The press includes a hydraulic extrusion mechanism, an extrusion head, an aluminum column positioning mechanism, an extrusion module, a cutting device, and a base. The hydraulic extrusion mechanism and the extrusion module are mounted on the base. The extrusion head and the aluminum column positioning mechanism are connected to the hydraulic extrusion mechanism, and the cutting device is connected to the extrusion module. The extrusion module includes an adjusting slide, a fixed base, adjusting cylinders, a rotating die, and a fixed die. Four adjusting cylinders are mounted on the fixed base, with piston rods passing through the fixed base and connecting to the adjusting slide. The adjusting slide and the fixed base each have an extrusion hole and a discharge hole. The fixed base has a fixed die groove for mounting the fixed die, and a positioning post for fixing the fixed die is provided within the fixed die groove. The adjusting slide has a rotating groove, within which a rotating die device is installed, and the rotating die is mounted on the rotating die device. Preferably, the rotating die device includes an adjusting motor, a worm gear, a rotating ring, a bearing, and a rotating ring positioning post.

[0004] While the aforementioned device can rotate the die via a rotating die mechanism to create a spiral shape on the inner wall of the aluminum profile, thereby increasing the lateral strength of the aluminum profile, in actual use, the die core inside the extrusion die cannot be replaced, and the extruder can only produce profiles of a single specification. Furthermore, different aluminum profiles (such as door and window profiles, industrial profiles, etc.) require die cores of different shapes and sizes, which cannot meet the market demand for diverse, small-batch products, thus limiting the company's order fulfillment capacity. Utility Model Content

[0005] The purpose of this invention is to provide a high beryllium aluminum alloy extrusion molding machine to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, a high beryllium aluminum alloy extrusion molding machine is provided, comprising an extrusion molding machine body, an extrusion head mounted on the extrusion molding machine body, an extrusion module disposed on one side of the extrusion head, the extrusion module including an extrusion die mounted on the end of the extrusion molding machine body, an installation hole provided on the extrusion die, a receiving space provided in the middle of the extrusion die, an extrusion molding die core installed inside the receiving space, an extrusion die cavity provided inside the extrusion molding die core, a blank cutting edge provided on one side of the extrusion die cavity, and a high beryllium aluminum alloy profile being extruded and molded inside the extrusion die cavity.

[0007] Preferably, the accommodating space is circular, and four sets of positioning grooves are evenly formed on the inner circumference of the accommodating space, with screw holes formed at the bottom of each of the four sets of positioning grooves.

[0008] Preferably, the extrusion molding die core includes a hollow cutting edge, an extrusion cavity, a positioning seat, and a countersunk hole. The extrusion molding die core is circular, and four sets of positioning seats are evenly installed on the outer circumference of the extrusion molding die core.

[0009] Preferably, the dimensions of the positioning seat and the positioning groove are matched, the positioning seat is inserted into the inside of the positioning groove, and the depth of the positioning groove is equal to the thickness of the positioning seat.

[0010] Preferably, each of the four positioning seats has a countersunk hole inside, and a fixing bolt is inserted inside the countersunk hole. The fixing bolt passes through the countersunk hole and is screwed into the screw hole. The cross-section of the positioning seat and the positioning groove is dovetail shaped.

[0011] Preferably, the extrusion molding die core is positioned and installed inside the extrusion die by four sets of positioning grooves, and the extrusion molding die core is fixed inside the extrusion die by eight sets of fixing bolts.

[0012] Preferably, the axial cross-section of the extrusion die and the extrusion molding die core is a concentric circle structure, and the thickness of the extrusion molding die core is equal to the depth of the accommodating space.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model allows for the prefabrication of extrusion cavities of various shapes using different die cores, facilitating the replacement of extrusion molding die cores with different shaped cavities. This adapts to products of different shapes, meeting market demands for diverse and small-batch products, improving order fulfillment capabilities, and enhancing market competitiveness. The extrusion molding die core and the extrusion mold adopt a separate structure. When different shapes of profiles need to be produced, only the fixing bolts need to be removed and the die core replaced, without the need to replace the entire mold. This reduces mold costs, simplifies core replacement operations, reduces labor costs and equipment downtime, and is particularly suitable for diverse and small-batch production scenarios.

[0015] 2. This utility model, through the design of four sets of positioning grooves and positioning seats, can quickly position and install the extrusion molding die core inside the extrusion die. The cooperation of the positioning grooves and positioning seats provides initial positioning rigidity, while the fixing bolts achieve secondary tightening, ensuring that the die core does not shift or deviate when subjected to high pressure during the extrusion process, thus guaranteeing the dimensional accuracy and surface quality of the profile.

Detailed Implementation

[0023] Please see Figure 1-6 This utility model provides a high beryllium aluminum alloy extrusion molding machine, including an extrusion molding machine body 300, an extrusion head 200 installed on the extrusion molding machine body 300, an extrusion module 100 provided on one side of the extrusion head 200, the extrusion module 100 including an extrusion die 1 installed at the end of the extrusion molding machine body 300, an installation hole 2 opened on the extrusion die 1, an accommodating space 3 opened in the middle of the extrusion die 1, an extrusion molding die core 5 installed inside the accommodating space 3, an extrusion die cavity 52 opened inside the extrusion molding die core 5, an empty cutting edge 51 provided on one side of the extrusion die cavity 52, and a high beryllium aluminum alloy profile 7 is extruded and formed inside the extrusion die cavity 52.

[0024] Working principle: The heated high beryllium aluminum alloy ingot is fed into the extrusion cylinder of the extrusion molding machine body 300. Its rear end is pushed by the extrusion head 200. The extrusion head 200 generates hundreds to thousands of tons of pressure through the hydraulic system, which extrudes the high beryllium aluminum alloy ingot towards the extrusion die 100. Under high pressure, the high beryllium aluminum alloy ingot is forced through the extrusion cavity 52 on the extrusion die 1, undergoes plastic flow, and finally forms a continuous profile with the same die hole shape, namely the high beryllium aluminum alloy profile 7.

[0025] The extrusion die 1 has a receiving space 3. The extrusion molding core 5 can be positioned and installed using the receiving space 3 and four sets of positioning grooves 4 on its outer circumference. After positioning, the fixing bolts 6 pass through the countersunk holes 54 and are screwed into the bolt holes 41, completing the fixed installation between the extrusion molding core 5 and the extrusion die 1. The design of the four sets of positioning grooves 4 and positioning seats 53 allows for quick positioning and installation of the extrusion molding core 5 inside the extrusion die 1. It also facilitates the replacement of extrusion molding cores 5 with different shaped extrusion cavities 52, thus adapting to different shaped products, meeting market demands for multi-variety, small-batch products, and improving the company's order fulfillment capacity. The extrusion molding core 5 and the extrusion die 1 adopt a separate structure. When producing profiles of different shapes, only the fixing bolts 6 need to be removed and the core replaced, without replacing the entire die, reducing die costs, especially for multi-variety products. Small-batch production scenarios; four positioning structures: positioning groove 4 and positioning seat 53, providing stable guidance, enabling the replaced die core to be quickly reset, reducing debugging time, and adapting to the production needs of frequent model changes; different die cores can be prefabricated with various shapes of extrusion cavities 52, and through quick core replacement, there is no need to customize a complete set of molds for each product, saving mold development costs; core replacement operation is simple, reducing labor costs and equipment downtime, especially suitable for small and medium-sized enterprises or new product trial production scenarios; traditional mold replacement is costly and time-consuming, making it difficult to economically produce small-batch products; this structure makes the production of small-batch orders possible through quick core replacement, avoiding the waste of resources of "large mold, small order"; the cooperation of positioning groove 4 and positioning seat 53 provides initial positioning rigidity, and fixing bolt 6 achieves secondary tightening, ensuring that the die core does not shift or deviate when subjected to high pressure during extrusion, ensuring the dimensional accuracy and surface quality of the profile.

The extrusion molding die core 5 is circular, and four sets of positioning seats 53 are evenly installed on the outer circumference of the extrusion molding die core 5.

[0028] In a preferred embodiment, the dimensions of the positioning seat 53 and the positioning groove 4 are matched, the positioning seat 53 is inserted into the interior of the positioning groove 4, and the depth of the positioning groove 4 is equal to the thickness of the positioning seat 53.

The fixing bolt 6 passes through the countersunk hole 54 and is screwed into the screw hole 41. The cross-section of the positioning seat 53 and the positioning groove 4 are both dovetail shaped.

[0030] In a preferred embodiment, the extrusion molding core 5 is positioned and installed inside the extrusion mold 1 by four sets of positioning grooves 4 and the extrusion molding core 5 is fixed inside the extrusion mold 1 by eight sets of fixing bolts 6.

[0031] In a preferred embodiment, the axial cross-section of the extrusion die 1 and the extrusion molding core 5 is a concentric circle structure, and the thickness of the extrusion molding core 5 is equal to the depth of the accommodating space 3.
