Description

Technical Field

[0001] This utility model belongs to the field of sheet metal forming, and specifically relates to an extrusion forming device for magnesium alloy sheets. Background Technology

[0002] Currently, magnesium alloys are alloys composed of magnesium as a base and other elements added. Their characteristics include: low density, high strength, high elastic modulus, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloys, and good resistance to corrosion from organic matter and alkalis. However, magnesium alloy sheets require appropriate forming equipment when processing into different shapes.

[0003] However, when magnesium alloy sheets are formed, they need to be extruded by an extrusion device. But because long sheets tend to curl up on both sides during stamping, the curled sheets need to be manually flattened before subsequent stamping can be completed, which reduces stamping efficiency.

[0004] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a magnesium alloy sheet extrusion molding device to solve the problem that when existing magnesium alloy sheets are being formed, they need to rely on an extrusion device to extrude the sheets. However, because longer sheets tend to curl upwards on both sides during stamping, the curled sheets need to be manually flattened before subsequent stamping can be completed, which leads to a decrease in stamping efficiency. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-7 As shown, the magnesium alloy sheet extrusion forming device includes: a support mechanism 1, which has assembly holes 101 that are bidirectionally connected to the upper and lower sides at the four corners of the inside of the support mechanism 1, and a guide rail mechanism 2 is fixedly connected to the top of the support mechanism 1.

[0027] The guide rail mechanism 2 houses a moving component 202. A longitudinally arranged guide component 203 is fixedly connected to the front end of the moving component 202. A servo push rod 3 is fixedly connected to the bottom surface of the guide component 203. The main body of the servo push rod 3 is longitudinally arranged. A connecting component 301 is fixedly connected to the bottom surface of the servo push rod 3. Four side plate components 3012 are fixedly connected to the outer side of the connecting component 301 in opposite directions. A support component 302 is slidably connected to the inner side of the side plate components 3012. A U-shaped bracket component 3021 is fixedly connected to the side of the support component 302 furthest from the side plate components 3012. The inner side of component 3021 is rotatably connected to pressure roller assembly 3022. Pressure roller assembly 3022 is a solid structure and is normally inclined to the outside. The outer side of connecting component 301 is fixedly connected to guide block assembly 3011 with protruding structure. There are two guide block assemblies 3011, which are arranged opposite to each other. The bottom end face of guide component 203 is fixedly connected to extrusion assembly 2031. Extrusion assembly 2031 matches the forming groove 1021 opened in forming component 102. There are two slider assemblies 2021, which are arranged opposite to each other.

[0028] Among them, a forming component 102 is fixedly connected to the top surface of the support mechanism 1. The top surface of the forming component 102 is provided with a groove, which is a forming groove 1021. A guide groove 1022 is provided on the top surface of the forming component 102. A workpiece 1023 is installed at the top of the guide groove 1022. An extrusion groove 1024 is provided inside the workpiece 1023.

[0029] The guide rail mechanism 2 is internally fixedly connected to a longitudinally arranged hydraulic push rod 201, the bottom end of which is connected to the top end of the moving component 202, and the moving component 202 is fixedly connected to a slider assembly 2021 on the outside.

[0030] When in use, before starting the magnesium alloy sheet extrusion molding operation, first place the magnesium alloy sheet (i.e., workpiece 1023) on the forming component 102 at the top of the support mechanism 1, and ensure that the sheet is accurately placed in the guide groove 1022 opened at the top of the forming component 102. At this time, all components of the entire device are in the initial state, ready for the subsequent extrusion molding operation.

[0031] The hydraulic push rod 201 installed inside the guide rail mechanism 2 is activated. The hydraulic push rod 201 is arranged longitudinally, and its bottom end is connected to the top end of the moving component 202. When the hydraulic push rod 201 is working, it pushes the moving component 202 to move downward along the guide rail mechanism 2. Since the front end of the moving component 202 is fixedly connected to the longitudinally arranged guide component 203, and the bottom end surface of the guide component 203 is fixedly connected to the pressing component 2031, when the moving component 202 moves downward, it will simultaneously drive the guide component 203 and the pressing component 2031 to move downward together.

[0032] At this time, the guide component 203 guides the extrusion component 2031 to move accurately toward the magnesium alloy sheet along the direction of the guide groove 1022. When the extrusion component 2031 contacts the sheet, it applies pressure to the sheet as it continues to move downward. Because the extrusion component 2031 matches the forming groove 1021 opened in the forming component 102, the sheet is gradually extruded into the forming groove 1021 under pressure, thereby realizing automated extrusion forming operation and making the sheet initially form the required shape.

[0033] After extrusion molding, the magnesium alloy sheet is long and its two sides often curl upwards. At this time, the servo push rod 3 installed on the bottom surface of the guide component 203 is activated. The servo push rod 3 is set vertically and its bottom end is connected to the connecting component 301. When the servo push rod 3 is working, it pushes the connecting component 301 to move downwards.

[0034] Four side plate assemblies 3012 are fixedly connected to the outer side of the connecting assembly 301 in opposite directions. The support assembly 302 is slidably connected to the inner side of the side plate assemblies 3012. Therefore, when the connecting assembly 301 moves downward, it drives the support assembly 302 to move downward. A U-shaped bracket assembly 3021 is fixedly connected to the side of the support assembly 302 away from the side plate assemblies 3012. The pressure roller assembly 3022 is rotatably connected to the inner side of the bracket assembly 3021. As the support assembly 302 moves downward, the two pressure roller assemblies 3022 are unfolded outward through the bracket assembly 3021. The pressure roller assembly 3022 is normally tilted outward and is a solid structure. After unfolding, the pressure roller assembly 3022 contacts the upturned edge of the board. During the process of the pressure roller assembly 3022 contacting and rolling with the board, the pressure of the pressure roller and the rolling friction are used to gradually flatten the upturned edge of the board, realizing an automated flattening operation to facilitate further processing that may be performed later.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
