Description

Technical Field

[0001] This invention relates to a die surface fine grinding device, and more particularly to a die surface fine grinding device for aluminum profile extrusion, belonging to the field of aluminum profile extrusion technology. Background Technology

[0002] Currently, aluminum extrusion is increasingly used in various industries. Aluminum extrusion molding, or aluminum extrusion forming, is a plastic processing method that applies strong pressure to aluminum billets placed in a die cavity or extrusion cylinder, forcing the aluminum billets to undergo directional plastic deformation and be extruded from the die orifice of the extrusion die, thereby obtaining parts or semi-finished products with the required cross-sectional shape, size, and certain mechanical properties. Aluminum profile extrusion requires the use of extrusion dies, which are generally thick circular steel discs containing one or more openings to form the desired profile. They are usually made of H-13 die steel and heat-treated to withstand the pressure and heat of hot aluminum passing through the die.

[0003] After the extrusion die is formed by milling, it still needs to be finely ground before it can be used. In the current technology, people usually use hand-held grinding equipment to finely grind the inner surface of the die to make the die usable. This fine grinding method requires a lot of time and labor. When workers use hand-held grinding equipment for a long time, they will experience work fatigue, which will reduce work efficiency and greatly reduce the efficiency of die fine grinding. Moreover, the inner surface of the die has different shapes, so the quality of die grinding cannot be controlled and may result in unqualified fine grinding quality.

[0004] Therefore, it is urgent to improve the surface grinding device for aluminum profile extrusion dies to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a surface grinding device for aluminum profile extrusion dies. An arc-shaped clamping plate holds the extrusion die and rotates it. A spring makes the inner surface of the die fit against a grinding rod driven by a motor, which can grind the dead corners inside the die, thereby greatly improving the quality of die grinding. Machine grinding is faster than manual grinding, reducing the labor intensity of workers and greatly reducing the time spent on die grinding, thus greatly improving the efficiency of die grinding.

[0008] A grinding chamber is fixedly installed on one side of the upper end of the grinding table. A mold clamping chamber is rotatably arranged inside the grinding chamber. Several evenly distributed springs are fixedly installed on the inner wall of the mold clamping chamber.

The output end of the stepper motor is rotatably connected to a rotating rod. The rotating rod passes through the outer wall of the grinding chamber and extends to the inner side of the grinding chamber. Gear 1 and Gear 2 are fixedly mounted on the rotating rod. A rotating rod fixing block is fixedly mounted on the inner bottom side of the grinding chamber. The rotating rod is rotatably disposed inside the rotating rod fixing block, and the rotating rod fixing block is disposed between Gear 1 and Gear 2.

[0013] Preferably, the outer wall of the mold clamping chamber is fixedly provided with a protrusion, a first female toothed rack, and a second female toothed rack. The protrusion is disposed between the first female toothed rack and the second female toothed rack, and the height of the protrusion is greater than the height of the first female toothed rack and the second female toothed rack.

[0014] Preferably, the lower end of the protrusion abuts against the rotating rod fixing block, the upper end of the protrusion abuts against the inner wall of the fine grinding chamber, the first female rack meshes with the first gear, and the second female rack meshes with the second gear.

[0015] Preferably, the transparent baffle has a guide groove for the pressure gauge at the position of the pressure gauge, the pressure gauge passes through the guide groove and extends into the interior of the fine grinding chamber, and the pressure gauge is slidably disposed between the extrusion mold and the inner wall of the fine grinding chamber.

[0017] A method for using a surface grinding device for aluminum profile extrusion dies includes the following steps;

[0018] Step 1: Start the horizontal travel motor to move the sliding mounting seat away from the fine grinding chamber, place the extrusion die between several arc-shaped clamps, and fix the extrusion die by the elastic force of the spring.

[0019] Step 2: Hold the sliding pressure ruler and extend it above the extrusion mold. Start the vertical lifting motor to control the vertical plate to descend.

[0022] Step 5: During the rotation of the extrusion die, its inner surface comes into contact with the grinding rod through the action of the spring force, and the grinding rod circulates to grind the inner surface of the extrusion die.

[0023] Step Six: After fine grinding is completed, start the horizontal walking motor to make the fine grinding rod slide out of the extrusion mold, and then remove the extrusion mold from the middle of the arc-shaped clamping plate for cleaning.

Machine precision grinding is faster than manual grinding, reducing the labor intensity of workers and significantly reducing the time spent on mold precision grinding, thus greatly improving the efficiency of mold precision grinding.

[0026] 2. This invention is applicable to the surface fine grinding of various extrusion dies, improves the forming effect of aluminum profile extrusion dies, greatly enhances the practicality of the fine grinding device, and can meet the fine grinding requirements of different dies by changing the specifications of the fine grinding rod, greatly expanding the applicability of the fine grinding device and making it suitable for large-scale promotion.

[0027] 3. The transparent baffle installed on the sliding mounting base of the present invention can prevent dust and iron filings from flying out during the fine grinding process, avoiding safety accidents caused by dust flying into the eyes of the wiping personnel. Therefore, it greatly improves the safety of the device, and at the same time, it is convenient to collect the iron filings after grinding, which is clean and environmentally friendly.

Detailed Implementation

[0036] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0037] like Figures 1-6 As shown, the surface grinding device for aluminum profile extrusion mold provided in this embodiment includes a grinding table 1. Two I-shaped slide rails 101 are fixedly arranged horizontally on the grinding table 1. A sliding mounting seat 2 is slidably arranged on the I-shaped slide rails 101. A grinding motor 3 is fixedly installed on the side of the sliding mounting seat 2. The output end of the grinding motor 3 is connected to a grinding rod 301 by a thread. A transparent baffle 201 is fixedly installed on the sliding mounting seat 2 at the position corresponding to the grinding rod 301. The grinding rod 301 is rotatably arranged inside the transparent baffle 201. A vertical plate 4 is slidably arranged on the sliding mounting seat 2. The vertical plate 4 is arranged between the transparent baffle 201 and the grinding motor 3. A pressure gauge 401 is slidably arranged on the upper end of the vertical plate 4. The pressure gauge 401 passes through the transparent baffle 201 and extends to the outside of the transparent baffle 201.

[0038] A grinding chamber 5 is fixedly installed on one side of the upper end of the grinding table 1. A mold clamping chamber 6 is rotatably arranged inside the grinding chamber 5. Several evenly distributed springs 601 are fixedly installed on the inner wall of the mold clamping chamber 6. One end of every two horizontally distributed springs 601 is fixedly connected to an arc-shaped clamping plate 602. An extrusion mold 7 is clamped between several arc-shaped clamping plates 602. The outer wall of the extrusion mold 7 abuts against the inner wall of the arc-shaped clamping plate 602, and the lowest point of the rotation of the inner surface of the extrusion mold 7 is greater than the height of the grinding rod 301. The arc-shaped clamping plate 602 clamps the extrusion mold 7 and rotates it. The springs 601 make the inner surface of the mold fit against the grinding rod 301 driven by the motor. This can grind the dead corners inside the mold, thereby greatly improving the quality of mold grinding. Machine grinding is faster than manual grinding, reduces the labor intensity of workers, and also greatly reduces the time spent on mold grinding, thus greatly improving the efficiency of mold grinding.

[0039] Furthermore, such as Figure 1 and Figure 5 As shown, a horizontal travel motor 202 is fixedly installed on one side of the sliding mounting base 2. A horizontal travel gear 203 is rotatably connected to the output end of the horizontal travel motor 202. The horizontal travel gear 203 is rotatably disposed inside the sliding mounting base 2. A horizontal rack 102 is provided on the I-shaped slide rail 101 corresponding to the position of the horizontal travel gear 203. The horizontal travel gear 203 is rotatably disposed on the lower side of the horizontal rack 102, which facilitates the left and right sliding control of the sliding mounting base 2 and greatly improves the flexibility of the device.

[0040] In addition, such as Figure 1 , Figure 2 and Figure 5 As shown, the sliding mounting base 2 has a vertical plate guide groove 204 at the position corresponding to the vertical plate 4. A motor fixing plate 205 is fixedly installed on the upper side of the sliding mounting base 2. A vertical lifting motor 206 is fixedly installed on one side of the motor fixing plate 205. A vertical sliding gear 207 is rotatably connected to the output end of the vertical lifting motor 206. The vertical sliding gear 207 is set on the other side of the motor fixing plate 205, which effectively adjusts the pressure gauge 401 up and down, thereby pressing it down on the extrusion mold 7, so as to facilitate the feeding of the fine grinding rod 301 into the extrusion mold 7.

[0041] The vertical plate 4 slides vertically inside the vertical plate guide groove 204. A vertical rack 402 is provided on the side of the vertical plate 4 near the vertical sliding gear 207. The vertical sliding gear 207 meshes with the vertical rack 402, which greatly improves the stability of the device.

[0042] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, a stepper motor 510 is fixedly installed on the side of the fine grinding chamber 5 away from the sliding mounting base 2 by screws. The output end of the stepper motor 510 is rotatably connected to a rotating rod 511. The rotating rod 511 passes through the outer wall of the fine grinding chamber 5 and extends to the inner side of the fine grinding chamber 5. Gear 1 512 and gear 2 513 are fixedly installed on the rotating rod 511. A rotating rod fixing block 501 is fixedly installed on the inner bottom side of the fine grinding chamber 5. The rotating rod 511 is rotatably disposed inside the rotating rod fixing block 501, and the rotating rod fixing block 501 is disposed between gear 1 512 and gear 2 513, so that the two gears are fixed to rotate in the same direction.

[0043] Meanwhile, the outer wall of the mold clamping chamber 6 is fixedly provided with a protrusion 611, a first female rack 612, and a second female rack 613. The protrusion 611 is located between the first female rack 612 and the second female rack 613, and the height of the protrusion 611 is greater than the height of the first female rack 612 and the second female rack 613. The lower end of the protrusion 611 abuts against the rotating rod fixing block 501, and the upper end of the protrusion 611 abuts against the inner wall of the fine grinding chamber 5. The first female rack 612 meshes with the first gear 512, and the second female rack 613 meshes with the second gear 513. This plays a role in positioning the mold clamping chamber 6, so that the mold clamping chamber 6 can rotate stably and efficiently inside the fine grinding chamber 5. It can also reduce the wear of the first female rack 612 and the second female rack 613 on the inner wall of the fine grinding chamber 5, and greatly improve the service life of the device.

[0044] Furthermore, such as Figure 1 Figure 2 and Figure 5 As shown, the transparent baffle 201 has a guide groove 211 for the pressure gauge 401 at the position corresponding to the pressure gauge 401. The pressure gauge 401 passes through the guide groove 211 and extends into the interior of the fine grinding chamber 5. The pressure gauge 401 is slidably disposed between the extrusion mold 7 and the inner wall of the fine grinding chamber 5, which facilitates the installation and removal of the pressure gauge 401 and makes the fine grinding preparation work more flexible.

[0045] In addition, such as Figure 1 As shown, the bottom side of the fine grinding table 1 is fixed with several evenly distributed support legs 103, which facilitates transportation and placement and greatly improves the practicality of the fine grinding device.

[0046] like Figures 1-6 As shown, the method of using the aluminum profile extrusion die surface fine grinding device provided in this embodiment includes the following steps;

[0047] Step 1: Start the transverse travel motor 202 to move the sliding mounting seat 2 away from the fine grinding chamber 5, place the extrusion mold 7 between several arc-shaped clamping plates 602, and fix the extrusion mold 7 by the elastic force of the spring 601.

[0048] Step 2: Hold the sliding pressure ruler 401 and extend it above the extrusion mold 7. Start the vertical lifting motor 206 to control the vertical plate 4 to descend. The vertical plate 4 drives the pressure ruler 401 to descend. The pressure ruler 401 presses down on the extrusion mold 7 to the height corresponding to the fine grinding rod 301 inside the extrusion mold 7.

[0049] Step 3: Start the horizontal walking motor 202 to extend the fine grinding rod 301 into the extrusion mold 7. Hold the pressure ruler 401 and follow the fine grinding rod 301 as it is inserted and slowly slide it out of the fine grinding chamber 5 until the transparent baffle 201 abuts against one side of the fine grinding chamber 5.

[0050] Step 4: Start the fine grinding motor 3 to drive the fine grinding rod 301 to rotate and grind the inner surface of the extrusion mold 7. At the same time, start the stepper motor 510 to drive the rotating rod 511 to rotate. The rotating rod 511 drives the mold clamping chamber 6 to rotate through gear meshing. The mold clamping chamber 6 clamps and fixes the extrusion mold 7 through the arc-shaped clamping plate 602 to make the extrusion mold 7 rotate.

[0051] Step 5: During the rotation of the extrusion die 7, its inner surface is in contact with the fine grinding rod 301 through the elastic force of the spring 601, and the fine grinding rod 301 cyclically grinds the inner surface of the extrusion die 7.

[0052] Step 6: After fine grinding is completed, start the transverse walking motor 202 to make the fine grinding rod 301 slide out from the inside of the extrusion mold 7, and then remove the extrusion mold 7 from the middle of the arc-shaped clamping plate 602 for cleaning.
