Description

Technical Field

[0001] This invention relates to the field of fixing device technology, and in particular to a fixing device and method for multi-batch polishing of aluminum profile extrusion die cores. Background Technology

[0002] The aluminum profile extrusion die core is a component of the extrusion die. It can be selectively installed according to the shape of the aluminum profile. Its main function is to guide the hot-melt aluminum profile and improve the smoothness of the aluminum profile flow in the die. After the die core of the aluminum profile extrusion die is formed by electrical discharge machining, it needs further grinding and polishing to achieve the surface flatness required for assembly. Due to the irregular shape of the die core end, the grinding and polishing operation is usually carried out manually by the operator. During the grinding and polishing process, the die core needs to be clamped and fixed by a fixing device, which is generally a threaded clamp. In actual use, the operator found the following problems with this type of fixing device: Problem 1: Mold cores of the same type cannot be fixed and polished together; Question 2: During grinding, the setting angle of the mold core cannot be adjusted. When grinding at certain angles, the operator needs to adjust their own angle to adapt to the setting angle of the mold core. Problem 3: Existing fixing devices generally use a single threaded clamping method, which makes it difficult to control the pressure applied to the mold core, and can easily lead to excessive deformation or insecure clamping. To address the above issues, we propose a multi-batch polishing fixing device for aluminum profile extrusion die cores and its usage method. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a multi-batch polishing fixing device and method for aluminum profile extrusion die cores, which solves the problems existing in the existing fixing equipment.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a multi-batch polishing and fixing device for aluminum profile extrusion die cores, comprising a fixed base and two sets of side support members fixed to both ends of the surface of the fixed base by bolts. A rotating shaft is installed between the two sets of side support members. An aluminum profile extrusion die core placement platform is sleeved on the outside of the rotating shaft. The aluminum profile extrusion die core placement platform is located between the two sets of side support members and abuts against the two sets of side support members. A sliding groove is opened inside the aluminum profile extrusion die core placement platform. An aluminum profile extrusion die core fixing component that can slide along the sliding groove is arranged inside the sliding groove. The aluminum profile extrusion die core fixing component and the aluminum profile extrusion die core placement platform cooperate to form a space for placing the aluminum profile extrusion die core. The aluminum profile extrusion die core fixing component cooperates with the aluminum profile extrusion die core placement platform to fix the aluminum profile extrusion die core.

[0005] Preferably, the slide is L-shaped, with its two ends penetrating the side and top surfaces of the aluminum profile extrusion die core placement platform, respectively, and the outer wall surface of the aluminum profile extrusion die core fixing assembly closely fitting the inner wall surface of the slide.

[0006] Preferably, the surface of the aluminum profile extrusion die core placement platform is provided with a rectangular protrusion at the end of the slide groove. The rectangular protrusion, together with the aluminum profile extrusion die core fixing assembly, forms a space for placing the aluminum profile extrusion die core.

[0007] Preferably, the aluminum profile extrusion die core fixing assembly includes a core fixing clamping block, a clamping block limiting bolt, a guide rod, and a spring. Two sets of core fixing clamping blocks are provided, and the two sets of core fixing clamping blocks are arranged side by side in the slide groove. The clamping block limiting bolt passes through the slide groove and is threaded to the bottom end of the core fixing clamping block. The guide rod is provided on the side of one set of core fixing clamping blocks and passes through the other set of core fixing clamping blocks. The spring is sleeved on the outside of the guide rod, and the two ends of the spring are respectively connected to the outer wall surface of the two sets of core fixing clamping blocks.

[0008] Preferably, the mold core fixing clamping block has a through hole in the middle, and a slide groove shielding plate is sleeved inside the through hole. The width of the slide groove shielding plate is wider than the width of the top opening of the slide groove, and the slide groove shielding plate covers the top of the slide groove to close the top of the slide groove.

[0009] Preferably, the two ends of the slide shield plate protrude downwards, and the two ends of the slide groove are provided with grooves that match the downward protrusion of the slide shield plate. The slide shield plate forms a nested and fixed structure with the downward protrusion and the groove of the slide groove.

[0010] Preferably, a gap is maintained between the bottom of the aluminum profile extrusion die core placement platform and the fixed base, and the aluminum profile extrusion die core placement platform forms a positive and negative rotation adjustment space with the rotation axis as the axis.

[0011] Preferably, a threaded hole is provided on one side of the fixed base, and a mold core placement platform clamping assembly is provided in the threaded hole. The end of the mold core placement platform clamping assembly abuts against the side of the aluminum profile extrusion mold core placement platform.

[0012] Preferably, the mold core placement platform clamping assembly includes a screw and a rubber clamping plate. The screw is threadedly connected to a threaded hole on one side of the fixed base, and the rubber clamping plate is rotatably connected to the end of the screw.

[0013] A method for using a multi-batch polishing fixing device for aluminum profile extrusion die cores includes the following steps. A. Prepare the mold core that needs to be polished; A1. Place the prepared mold core on the surface of the aluminum profile extrusion mold core placement table; A2, manually arrange each set of mold cores side by side and align the bottoms of each set of mold cores; B, restricting the mold core; B1, push the mold core fixing clamping block on the outer side of the mold core so that the mold core fixing clamping block slides along the slide groove toward the mold core; B2, the outer mold core fixing clamping block pushes the spring during movement. After the spring deforms to a certain extent, it pushes the inner mold core fixing clamping block to move laterally along the slide groove. B3, the inner mold core fixing clamping block abuts against the mold core of the aluminum profile extrusion die, and continues to push the outer mold core fixing clamping block. The outer mold core fixing clamping block continues to push the spring to deform the spring. When the outer mold core fixing clamping block cannot be pushed, the clamping block limiting bolt set on the outer mold core fixing clamping block is rotated to make the clamping block limiting bolt initially fix the position of the outer mold core fixing clamping block. B4. Continue to rotate the clamping block limiting bolt on the inner mold core fixing clamping block to further fix the inner mold core fixing clamping block. After the position of the inner mold core fixing clamping block is fixed, it will work with the outer mold core fixing clamping block to form a double fixation. C. Adjust the tilt angle of the mold core; C1, push the aluminum profile extrusion die core placement platform to rotate to the required tilt angle; C2, rotate the screw, and the screw will push the rubber clamping plate to move laterally through the threaded connection with the threaded hole on the side of the fixed base; C3, the rubber clamping plate abuts against the side wall of the aluminum profile extrusion die core placement platform during the lateral movement. The rubber clamping plate keeps the aluminum profile extrusion die core placement platform at the angle after rotation through the friction between itself and the aluminum profile extrusion die core placement platform. C4. When adjusting the aluminum profile extrusion die core placement table for the second time, repeat steps C1-C3 in reverse.

[0014] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. In this invention, the interior of the aluminum profile extrusion die core placement platform is provided with a sliding groove, and the interior of the sliding groove is provided with an aluminum profile extrusion die core fixing component. The aluminum profile extrusion die core fixing component and the aluminum profile extrusion die core placement platform cooperate to form a space for placing the aluminum profile extrusion die core. Multiple sets of aluminum profile extrusion die cores can be placed side by side without the need for individual clamping and fixing of each set of aluminum profile extrusion die cores.

[0015] 2. In this invention, a slide groove shielding plate is added to seal the top of the slide groove, so that the grinding debris will not fall into the slide groove and avoid the debris affecting the sliding of the aluminum profile extrusion die core fixing assembly in the slide groove. 3. In this invention, an aluminum profile extrusion die core fixing assembly is provided to reduce rigid extrusion of the die core. After the clamping block limit bolts are initially fixed, the inner die core fixing clamping block can stably provide extrusion fixing capability of the die core under the elastic force of the guide rod. The double fixing is further improved by the pressure restriction of the spring. 4. In this invention, the aluminum profile extrusion die core placement platform can rotate around the rotation axis in positive and negative angles. After rotating to the correct position, the aluminum profile extrusion die core placement platform can keep the aluminum profile extrusion die core at the same tilt angle and be fixed by the core placement platform clamping assembly, so as to better adjust different grinding angles.

[0018] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified. Example

[0019] like Figures 1-6 As shown, the present invention provides a multi-batch polishing and fixing device for aluminum profile extrusion die cores, including a fixed base 1 and two sets of side support members 2 fixed to both ends of the surface of the fixed base 1 by bolts. A rotating shaft 3 is installed between the two sets of side support members 2. An aluminum profile extrusion die core placement platform 4 is sleeved on the outside of the rotating shaft 3. The aluminum profile extrusion die core placement platform 4 is located between the two sets of side support members 2 and abuts against the two sets of side support members 2. A sliding groove 5 is opened inside the aluminum profile extrusion die core placement platform 4. An aluminum profile extrusion die core fixing component 6 that can slide along the sliding groove 5 is arranged inside the sliding groove 5. The aluminum profile extrusion die core fixing component 6 and the aluminum profile extrusion die core placement platform 4 cooperate to form a space for placing the aluminum profile extrusion die core. The aluminum profile extrusion die core fixing component 6 cooperates with the aluminum profile extrusion die core placement platform 4 to fix the aluminum profile extrusion die core.

[0020] The slide 5 is L-shaped, with its two ends penetrating the side and top surfaces of the aluminum profile extrusion die core placement platform 4, respectively. The outer wall of the aluminum profile extrusion die core fixing component 6 is tightly fitted to the inner wall of the slide 5. A rectangular protrusion is provided on the surface of the aluminum profile extrusion die core placement platform 4 at the end of the slide 5. The rectangular protrusion, together with the aluminum profile extrusion die core fixing component 6, forms a space for placing the aluminum profile extrusion die core. Multiple sets of aluminum profile extrusion die cores are arranged on the surface of the aluminum profile extrusion die core placement platform 4 manually, and the ends of the aluminum profile extrusion die cores are aligned. At this time, the die cores are combined, placed, and arranged.

[0021] The aluminum profile extrusion die core fixing assembly 6 includes a core fixing clamping block 61, a clamping block limiting bolt 62, a guide rod 63, and a spring 64. Two sets of core fixing clamping blocks 61 are arranged side-by-side in a slide groove 5. The clamping block limiting bolt 62 passes through the slide groove 5 and is threaded to the bottom end of the core fixing clamping block 61. The guide rod 63 is located on the side of one set of core fixing clamping blocks 61 and simultaneously passes through the other set of core fixing clamping blocks 61. The spring 64 is sleeved on the outside of the guide rod 63, and the spring 64... Both ends are connected to the outer walls of two sets of mold core fixing clamping blocks 61 respectively. After multiple sets of aluminum profile extrusion mold cores are arranged and placed between the aluminum profile extrusion mold core placement platform 4 and the aluminum profile extrusion mold core fixing assembly 6, the mold core fixing clamping block 61 on the outer side relative to the mold core is pushed so that the mold core fixing clamping block 61 slides along the slide groove 5 toward the mold core. During the movement, the outer mold core fixing clamping block 61 first pushes the spring 64. After the spring 64 deforms to a certain extent, the inner mold core fixing clamping block 61 is pushed by the spring 64, which no longer deforms. Moving laterally along the slide 5, after the inner mold core fixing clamping block 61 contacts the mold core of the aluminum profile extrusion die, the outer mold core fixing clamping block 61 continues to be pushed. At this time, the outer mold core fixing clamping block 61 will continue to push the spring 64 to deform the spring 64. When the outer mold core fixing clamping block 61 can no longer be pushed, the clamping block limiting bolt 62 set on the outer mold core fixing clamping block 61 is rotated to initially fix the outer mold core fixing clamping block 61 in position. After the initial position fixation of the outer mold core fixing clamping block 61 is completed, the rotation continues. By moving the clamping block limiting bolt 62 on the inner mold core fixing clamping block 61, the inner mold core fixing clamping block 61 can be further fixed. Compared with the current direct screw compression method, this fixing method can reduce the rigid compression of the mold core through the deformation of the spring 64. At the same time, after the clamping block limiting bolt 62 is initially fixed in position, the inner mold core fixing clamping block 61 can stably provide the compression fixing ability of the mold core under the elastic force of the spring 64. The double fixing and the pressure restriction by the spring 64 further improve the fixing ability.

[0022] A through hole 65 is provided in the middle of the mold core fixing clamping block 61. A slide groove shielding plate 7 is fitted inside the through hole 65, and the width of the slide groove shielding plate 7 is wider than the width of the top opening of the slide groove 5. The slide groove shielding plate 7 covers the top of the slide groove 5 and closes the top of the slide groove 5. The two ends of the slide groove shielding plate 7 protrude downwards, and the two ends of the slide groove 5 are provided with grooves that match the downward protrusion of the slide groove shielding plate 7. The slide groove shielding plate 7 forms a nested fixing structure with the downward protrusion and the groove of the slide groove 5. The slide groove shielding plate 7 is used to fix the mold core of the aluminum profile extrusion mold. When component 6 is installed into the slide groove 5, the slide groove shielding plate 7 can be nested into the slide groove 5 simultaneously. At the same time, through the formed nested fixing structure, it is stably fixed in the slide groove 5, ensuring that the slide groove shielding plate 7 itself will not fall out as the aluminum profile extrusion die core fixing component 6 slides in the slide groove 5. At this time, the slide groove shielding plate 7 plays a role in sealing the top of the slide groove 5, so that the debris during grinding will not fall into the interior of the slide groove 5, and avoid the debris affecting the sliding of the aluminum profile extrusion die core fixing component 6 in the slide groove 5.

[0023] A gap is maintained between the bottom of the aluminum profile extrusion die core placement platform 4 and the fixed base 1. The aluminum profile extrusion die core placement platform 4 forms a positive and negative rotation adjustment space with the rotation shaft 3 as the axis. When the aluminum profile extrusion die core is stably fixed on the aluminum profile extrusion die core placement platform 4 by the cooperation of the aluminum profile extrusion die core fixing component 6 and the aluminum profile extrusion die core placement platform 4, the aluminum profile extrusion die core placement platform 4 can be pushed to rotate the aluminum profile extrusion die core placement platform 4 with the rotation shaft 3 as the axis in positive and negative angles. After rotating to the position, the aluminum profile extrusion die core placement platform 4 can keep the aluminum profile extrusion die core at the same tilt angle.

[0024] To fix the setting angle of the aluminum profile extrusion die core placement platform 4, a threaded hole is provided on one side of the fixing base 1. A die core placement platform clamping assembly 8 is installed in the threaded hole. The end of the die core placement platform clamping assembly 8 abuts against the side of the aluminum profile extrusion die core placement platform 4. The die core placement platform clamping assembly 8 includes a screw 81 and a rubber clamping plate 82. The screw 81 is threaded into the threaded hole on one side of the fixing base 1, and the rubber clamping plate 82 is rotatably connected to the end of the screw 81. The end of the rubber clamping plate 82 abuts against the side of the aluminum profile extrusion die core placement platform 4. 4. When rotated to the desired tilt angle, rotate screw 81. Screw 81 pushes rubber clamping plate 82 to move laterally through the threaded connection with the threaded hole on the side of the fixed base 1. During the lateral movement, rubber clamping plate 82 abuts against the side wall of aluminum profile extrusion mold core placement platform 4. The friction between rubber clamping plate 82 and aluminum profile extrusion mold core placement platform 4 keeps aluminum profile extrusion mold core placement platform 4 at the angle after rotation, which facilitates the grinding operation of the operator. At the same time, in this way, the angle can be adjusted in real time during use, so as to better adapt to different angles required for grinding.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
