Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profile processing, and particularly relates to an aluminum profile die extrusion synchronous chemical polishing device and its process. Background Art

[0002] Aluminum alloy extrusion molding means putting an aluminum alloy blank heated to a soft state into the hopper of an extruder. Through the pressure of the extruder and the action of the die, the aluminum alloy blank is extruded and formed through the gap of the die under certain temperature and deformation conditions, so as to obtain the aluminum alloy material of the required shape. After the aluminum profile is formed, chemical polishing is required. Chemical polishing is to utilize the principles of chemical corrosion and surface passivation to form an extremely thin oxide film on the surface of the aluminum material and then remove the oxide film to make the surface of the aluminum material reach a mirror or satin finish. When extruding and polishing the aluminum profile, an aluminum profile die extrusion synchronous chemical polishing device is needed. For the common aluminum profile die extrusion synchronous chemical polishing devices on the market, during the process of placing the aluminum alloy blank, whether it is manual placement or machine placement, it will cause impact and vibration to the aluminum alloy blank. In the long run, it is easy to cause deformation and aging of the contact components, affecting the use. Moreover, the formed die is supported by long-term force application, and it is easy to have slight displacement and virtual position at the installation position, affecting the forming effect, and it is relatively laborious to replace the die, affecting the processing efficiency. When chemically polishing the aluminum profile, the polishing efficiency is limited, and there will be undissolved particles precipitating at the bottom, affecting the chemical polishing effect. Summary of the Invention

[0005] In at least some embodiments, a linkage component is inserted through the inside of the telescopic column, both ends of the linkage component are embedded inside the top of the side piece, pins are inserted inside both ends of the linkage component, the bottom end of the pin is inserted inside the side piece, and the top pieces are fixedly welded together through a round rod; the right side of the side piece is fixedly welded to a triangular pushing component and drives the pushing component to move left and right together, a support piece is fixed at the bottom end inside the extrusion molding main body, the support piece is inserted inside the two side pieces and supports the side pieces to slide left and right, the inside of the force receiving component is an arc-shaped structure, and the telescopic column is inserted inside the force receiving component.

[0006] In at least some embodiments, a T-shaped slot is provided on each side of the fixing component, four cylindrical positioning components are fixed on the left side of the fixing component, the positioning components penetrate through the mold and are inserted inside the molding component; the left side of the mold is fitted and installed with the molding component, and a plug plate component is inserted inside each slot; the left side of the plug plate component is fixedly welded to a control piece, the bottom of the control piece is connected to a guide rod through a connecting plate, and the guide rod penetrates and is pulled inside the extrusion molding main body.

[0007] In at least some embodiments, inner rods are symmetrically welded to both inner ends of the polishing structure, and a pushing structure is slidably installed at the inner bottom end of the polishing structure; auxiliary plates arranged in a uniformly staggered manner are provided at the top end of the pushing structure, the auxiliary plates are inclined, and a driving structure is welded and fixed to each of the two sides of the pushing structure. A guide groove with a wavy structure is provided inside the driving structure, and an insertion structure is inserted into the guide groove and slides freely inside; a moving member is slidably installed outside the inner rods on the same side of both sides. The top end of the moving member is an inclined structure. The moving member on the left is welded and fixed to a stress rod. The bottom end of the outer end of the stress rod is an arc-shaped structure, and the bottom end of the outer end of the stress rod is in sliding contact with the upper part of the pushing assembly.

[0008] In at least some embodiments, the following steps are included:

[0009] 01. Select an appropriate amount of sodium hydroxide and sodium nitrate, then add 2 / 3 of tap water to the inside of the polishing structure. Control the addition of sodium hydroxide to dissolve inside the polishing structure. After the sodium hydroxide is dissolved, add sodium nitrate to dissolve, then add an additive, and then add tap water for dilution to form a polishing solution. Turn on the heating controller and set the temperature to 110 °C, so that the heating tube heats the polishing solution to 110 °C.

[0010] 02. Control the aluminum alloy blank to be placed in a heating furnace for heating. The heating time is 30 min. After the heating is completed, control the aluminum alloy blank to be placed inside the stress assembly;

[0011] 03. The stress assembly is stressed, compressing the spring and the contact block. Control the hydraulic cylinder to operate so that the telescopic column pushes the aluminum alloy blank into the forming assembly, and then apply pressure to extrude the aluminum alloy blank through the mold to form it;

[0012] 04. After the aluminum profile is formed, it falls into the polishing structure. While the telescopic column resets, it drives the linkage assembly, the side member, and the pushing assembly to move reciprocally. The upper part of the pushing assembly passes through the stress rod, and the moving member and the guide plate are controlled to move up and down through the stress rod. While the guide plate moves up and down, the diversion holes squeeze the polishing solution to flow upward, and then through the diversion of the triangular plate, the polishing solution impacts the aluminum profile to improve the polishing efficiency;

[0013] 05. While the moving member and the guide plate move up and down, drive the insertion structure to move together. The outer end of the insertion structure is inserted into the guide groove and moves up and down inside. Since the guide groove is a curved wavy structure, the driving structure drives the auxiliary plate and the pushing structure to move reciprocally, so that the auxiliary plate pushes the sediment and the chemical particles that are not completely melted to rise, making the particles uniformly contact the aluminum profile. Thus, the use of the device and its process are completed.

[0014] The present invention provides an aluminum profile mold extrusion synchronous chemical polishing device and its process, which has the following beneficial effects:

[0015] The bottom of the force-bearing component contacts the contact block and the spring. When the aluminum alloy blank is placed inside the force-bearing component for extrusion preparation, the force-bearing component eliminates the impact force by means of the elasticity of the contact block and the spring. At the same time, the upper part of the outer end of the force-bearing component contacts the lower part of the middle position of the limit component, restricting the force-bearing component to be used in the standard position and avoiding deformation of the force-bearing component after continuous force application.

[0016] After the mold is installed, the positioning head and the auxiliary component are inserted into the fixed component in a fitting manner. The positioning component of the fixed component penetrates the mold to initially position the mold. The positioning head and the auxiliary component are installed in a fitting manner with the fixed component by virtue of their own shapes. Through the fitting installation of multiple shapes, the occurrence of voids is avoided, and the service life of the mold is improved.

[0017] After the fixed component is installed, it is limited and fixed by inserting the plugboard component into the slot, enabling the fixed component to be quickly limited and fixed, improving the fixing speed and convenience of the mold, and avoiding the long mold replacement time from affecting the processing efficiency.

[0018] The guide plate moves up and down inside the polishing structure. The bottom of the diversion hole of the guide plate extrudes the polishing liquid, causing the polishing liquid to flow inward through the diversion hole. Then, the triangular plate controls the upward flow of the polishing liquid, enabling the polishing liquid to impact the aluminum profile and improving the polishing efficiency.

[0019] While the guide plate moves up and down, it drives the insertion structure to move up and down together. The outer end of the insertion structure slides inside the guide groove. Since the guide groove is a curved wavy structure, it drives the driving structure, the auxiliary plate, and the pushing structure to move reciprocally together, enabling the auxiliary plate to push the sediment and undissolved chemical particles to mix and surge at the bottom end inside the polishing structure, making them evenly contact the outside of the aluminum profile and avoiding excessive precipitation.

[0020] During extrusion, the telescopic column drives the linkage component, the side component, and the pushing component to move reciprocally. The top of the pushing component contacts the force-bearing rod, controlling the up and down movement of the force-bearing rod, and further driving the moving part and the guide plate to move up and down. After the aluminum profile is extruded and formed through the mold, by means of the telescopic power of the telescopic column, the movement of the aluminum profile is synchronously controlled for chemical polishing.

The guide rod 208 is pulled inside the extrusion molding body 1 to drive the control member 207 to displace up and down in a guided manner.

[0041] In the embodiment of the present disclosure, as Figure 7 With Figure 8As shown, inner rods 301 are symmetrically welded to both inner ends of the polishing structure 3 to control the up-and-down displacement of the moving member 305. A pushing structure 302 is slidably installed at the inner bottom end of the polishing structure 3 to drive the auxiliary plate 303 to push and melt the unmelted chemical particles at the inner bottom end of the polishing structure 3. At the top of the pushing structure 302, there are auxiliary plates 303 arranged in a uniformly staggered manner. The auxiliary plates 303 are inclined. On both sides of the pushing structure 302, a driving structure 304 is respectively welded and fixed. Inside the driving structure 304, there is a guide groove with a wavy structure.

The bottom end of the outer end of the force-receiving rod 308 is in sliding contact with the upper part of the pushing assembly 103. While the pushing assembly 103 moves reciprocally, the force-receiving rod 308 is controlled to drive the moving member 305, the guide plate 306, and the aluminum profile to move up and down, so that the aluminum profile moves up and down in the polishing liquid, improving the chemical polishing effect.

[0042] In at least some embodiments, the following steps are included:

[0043] 01. Select an appropriate amount of sodium hydroxide and sodium nitrate, then add 2 / 3 of tap water to the inside of the polishing structure 3. Control the sodium hydroxide to be added to the inside of the polishing structure 3 for dissolution. After the sodium hydroxide is dissolved, add sodium nitrate for dissolution, then add additives, and then add tap water for dilution to form a polishing liquid. Turn on the heating controller and set the temperature to 110 degrees Celsius, so that the heating tube heats the polishing liquid to 110 degrees Celsius.

[0044] 02. Control the aluminum alloy blank to be placed in the heating furnace for heating. The heating time is 30 min. After the heating is completed, control the aluminum alloy blank to be placed inside the force-receiving assembly 108;

[0045] 03. The force-receiving assembly 108 is stressed, compressing the spring and the contact block 107. Control the hydraulic cylinder to operate, so that the telescopic column pushes the aluminum alloy blank into the forming assembly, and then apply pressure to extrude the aluminum alloy blank through the mold 203;

[0046] 04. After the aluminum profile is formed, it falls into the interior of the polishing structure 3. While the telescopic column resets, it drives the linkage assembly 101, the side member 102, and the pushing assembly 103 to reciprocate. The upper part of the pushing assembly 103 passes through the force-bearing rod 308, and the force-bearing rod 308 controls the up and down movement of the moving part 305 and the guide plate 306. While the guide plate 306 moves up and down, the diversion holes squeeze the polishing liquid to flow upward, and then through the diversion of the triangular plate, the polishing liquid impacts the aluminum profile, improving the polishing efficiency;

[0047] 05. While the moving part 305 and the guide plate 306 move up and down, they drive the insertion structure 307 to move together. The outer end of the insertion structure 307 is inserted into the interior of the guide groove and moves up and down. Since the guide groove is a curved wavy structure, the driving structure 304 drives the auxiliary plate 303 and the pushing structure 302 to reciprocate, so that the auxiliary plate 303 pushes the sediment and the chemical particles that are not completely melted to rise, making the particles evenly contact the aluminum profile. Thus, the use of this device and its process are completed.

[0048] Working principle of this embodiment: First, control the polishing liquid to be used to be formulated and mixed inside the polishing structure 3. Then, pull the control member 207 upward to control the mold 203 to be embedded on the right side of the forming assembly, and control the fixing member 2 to move leftward to reset, so that the positioning member 202 penetrates through the mold 203 and inserts into the inside of the forming assembly. Then, control the control member 207 to move downward, so that the plug plate member 206 inserts into the inside of the slot 201, and the fixing member 2 is quickly fixed, improving the installation efficiency of the mold 203. After the mold 203 is installed, the positioning head 204 and the auxiliary member 205 are fitted and embedded inside the fixing member 2, improving the positioning and fixing effect on the mold 203 and avoiding the occurrence of virtual positions and deformations after the mold 203 is used for a long time. Then, put the heated aluminum alloy blank into the stress component 108. After the stress component 108 is stressed, it compresses the spring and the contact block 107, and eliminates the impact force by means of elasticity, avoiding deformation of the stress component 108 after long-term use. Then, control the hydraulic cylinder to operate by controlling the switch, so that the telescopic column pushes the aluminum alloy blank into the inside of the forming assembly, and then apply pressure to make the aluminum alloy blank extruded and formed through the mold 203. After the aluminum profile is formed, it falls into the inside of the polishing structure 3. While the telescopic column resets, it drives the linkage assembly 101, the side member 102 and the pushing assembly 103 to reciprocate. Above the pushing assembly 103, it passes through the stress rod 308, and controls the moving member 305 and the guide plate 306 to move up and down through the stress rod 308. While the guide plate 306 moves up and down, the diversion hole squeezes the polishing liquid to flow upward, and then through the diversion of the triangular plate, the polishing liquid impacts the aluminum profile, improving the polishing efficiency. While the moving member 305 and the guide plate 306 move up and down, they drive the insertion structure 307 to move together. The outer end of the insertion structure 307 inserts into the inside of the guide groove and moves up and down. Since the guide groove is a curved wavy structure, the driving structure 304 drives the auxiliary plate 303 and the pushing structure 302 to reciprocate, so that the auxiliary plate 303 pushes the sediment and the chemically incompletely dissolved particles upward, making the particles contact the aluminum profile evenly and improving the polishing uniformity.

The auxiliary plates (303) are inclined. On both sides of the pushing structure (302), there is respectively welded and fixed a driving structure (304). Inside the driving structure (304), there is a guide groove with a wavy structure. The insertion structure (307) is inserted into the guide groove for free sliding.

9. The synchronous chemical polishing device for extrusion of aluminum profile dies according to claim 8, wherein, Outside the inner rods (301) on the same side, there is slidably installed a moving member (305). The top of the moving member (305) has an inclined structure. The left moving member (305) is welded and fixed to the force-bearing rod (308). The bottom of the outer end of the force-bearing rod (308) has an arc-shaped structure. The bottom of the outer end of the force-bearing rod (308) is in sliding contact with the upper part of the pushing assembly (103).

10. The process of the synchronous chemical polishing device for extrusion of aluminum profile dies according to claim 9, wherein, It includes the following steps:

01. Select an appropriate amount of sodium hydroxide and sodium nitrate. Then add 2 / 3 of tap water into the polishing structure (3). Control the addition of sodium hydroxide into the polishing structure (3) for dissolution. After the sodium hydroxide is dissolved, add sodium nitrate for dissolution. Then add an additive, and then add tap water for dilution to form a polishing solution. Turn on the heating controller and set the temperature to 110 degrees Celsius to heat the polishing solution to 110 degrees Celsius by the heating tube.

02. Control the aluminum alloy blank to be put into the heating furnace for heating. The heating time is 30 minutes. After heating is completed, control the aluminum alloy blank to be put into the force-bearing assembly (108).

03. The force-bearing assembly (108) is stressed, compressing the spring and the contact block (107). Control the hydraulic cylinder to operate so that the telescopic column pushes the aluminum alloy blank into the interior of the forming assembly. Then apply pressure to extrude and form the aluminum alloy blank through the mold (203).

04. After the aluminum profile is formed, it falls into the interior of the polishing structure (3). While the telescopic column resets, it drives the linkage assembly (101), the side member (102), and the pushing assembly (103) to reciprocate. The upper part of the pushing assembly (103) passes through the force-bearing rod (308), and the force-bearing rod (308) controls the up-and-down movement of the moving part (305) and the guide plate (306). While the guide plate (306) moves up and down, the diversion holes squeeze the polishing liquid to flow upward, and then through the diversion of the triangular plate, the polishing liquid impacts the aluminum profile, improving the polishing efficiency; 05. While the moving part (305) and the guide plate (306) move up and down, they drive the insertion structure (307) to move together. The outer end of the insertion structure (307) is inserted into the guide groove and moves up and down. Since the guide groove is a curved wavy structure, the driving structure (304) drives the auxiliary plate (303) and the pushing structure (302) to reciprocate, so that the auxiliary plate (303) pushes the sediment and the chemical particles that are not completely dissolved to rise, making the particles evenly contact the aluminum profile. Thus, the use of this device and its process are completed.
