Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum extruders, in particular to an extruder for aluminum production. Background Art

[0002] Aluminum products are made of aluminum and other alloy elements. They are usually first processed into castings, forgings, foils, plates, strips, tubes, rods, profiles, etc., and then made through processes such as cold bending, sawing, drilling, assembly, and coloring. The main metal element is aluminum, and some alloy elements are added to improve the performance of aluminum. An extruder is needed when shaping aluminum.

Rotatably connected to the inner side of the upper end of the chassis 1 is a rotating disc 8. Inserted into the upper end of the rotating disc 8 is an extrusion die 9. An inserting hole 14 is opened inside the extrusion die 9. A clamping groove 15 is opened inside the inserting hole 14. Fixedly installed at the upper end of the rotating disc 8 is a fixing mechanism 10. The rotating disc 8 is clamped with the clamping groove 15 through the fixing mechanism 10. The upper end of the extrusion die 9 is equally angularly provided with forming cavities 91; Inside the extrusion die 9 is also provided a spring ejector pin. The ejecting part of the spring ejector pin is arranged in the forming cavity 91. Its basic principle and usage are the same as those of the demolding ejector pin in the FPC reinforcing sheet precision stamping die disclosed in the patent publication number CN217666001U. Its main purpose is to facilitate the demolding of products in a timely manner. It is a relatively mature existing technology; The center part of the rotating disc 8 is connected to the output end of the motor installed inside the chassis 1, which can realize the rotation of the rotating disc 8. And the motor is controlled by a control module outside the chassis 1.

[0024] The fixing mechanism 10 includes a mounting block 103. The mounting block 103 is fixedly installed at the upper end of the rotating disk 8. A circular groove 105 is opened at the lower end of the mounting block 103. The inner side of the upper end of the mounting block 103 is rotatably connected to a rotating rod 102. A second rotating handle 101 is fixedly installed at the upper end of the rotating rod 102. The lower end of the rotating rod 102 extends into the inner side of the circular groove 105 and is fixedly installed with a first bevel gear 106. The mounting block 103 and the jack 14 are in an insertion connection. The outer side of the mounting block 103 is equiangularly provided with moving grooves 108. The inner side of the moving groove 108 is rotatably connected to a second screw rod 109. One end of the second screw rod 109 extends into the inner side of the circular groove 105 and is fixedly installed with a second bevel gear 107. The first bevel gear 106 and the second bevel gear 107 are in a meshing connection. One end of the second screw rod 109 away from the second bevel gear 107 is threadedly connected to a clamping block 104. One end of the clamping block 104 is slidably connected to the inner side of the moving groove 108. The clamping end of the clamping block 104 is clamped with the clamping groove 15 of the extrusion die 9. The extrusion die 9 and the mounting block 103 are inserted. At the same time, the lower end of the extrusion die 9 is inserted into the upper end of the rotating disk 8. After the insertion, the position of the clamping block 104 corresponds to the position of the clamping groove 15 at this time. Then operate the second rotating handle 101 to make the second rotating handle 101 rotate the rotating rod 102.

Due to the rotation of the second screw rod 109, the clamping block 104 threadedly connected to the outside can slide and expand in the moving groove 108. When the clamping end of the clamping block 104 extends out of the moving groove 108, it can be clamped into the corresponding clamping groove 15 to complete the fixation of the extrusion die 9. On the contrary, when the second rotating handle 101 is operated in the reverse direction to indirectly separate the clamping block 104 from the clamping groove 15 of the extrusion die 9, the extrusion die 9 can be conveniently removed from the rotating disk 8 for replacement. Thus, it is convenient to produce and process aluminum materials with different specifications of extrusion dies 9 according to production requirements, and there is no need to replace the entire machine. Therefore, to a certain extent, it also greatly reduces the operating cost of the enterprise;

[0025] The adjusting mechanism 6 includes a mounting frame 601 which is fixedly installed at the lower end of the moving plate 3. A first screw rod 602 is rotatably connected to the inner side of the mounting frame 601.

A regulating seat 604 is slidably connected to the inner side of the lower end of the mounting frame 601. The regulating seat 604 is threadedly connected to the outer side of the first screw rod 602. The extrusion head 7 is threadedly connected to the lower end of the regulating seat 604. When using different extrusion dies 9, the extrusion head 7 is connected to the regulating seat 604 in a threaded form, which can facilitate the replacement of the extrusion head 7 according to different extrusion dies 9. Secondly, during the use process, the first screw rod 602 is rotated by the first rotating handle 603 to rotate on the mounting frame 601, so that the regulating seat 604 threadedly connected to the outer side of the second screw rod 109 slides on the mounting frame 601. At this time, it is convenient to adjust the extrusion head 7 according to the position of the forming cavity 91 on the extrusion die 9. Through this adjusting mechanism 6, the center of the matching extrusion head 7 can be adjusted to correspond to the center position of the forming cavity 91 on the corresponding extrusion die 9 during extrusion, which can facilitate the extrusion of aluminum by the extrusion head 7.

[0026] Reference Figure 4 , symmetrically fixed connections of limiting blocks 16 are arranged on the outer side of the clamping block 104. Limiting grooves 17 are arranged on the inner side of the moving groove 108. The limiting blocks 16 are slidably connected to the inner side of the limiting grooves 17. By sliding the limiting blocks 16 on the clamping block 104 in the limiting grooves 17 of the moving groove 108, it is possible to prevent the clamping block 104 from disengaging from the moving groove 108 during the adjustment and use processes.

[0027] Reference Figure 4 , a screw sleeve 18 is fixedly installed on the inner side of one end of the clamping block 104. One end of the clamping block 104 is threadedly connected to the second screw rod 109 through the screw sleeve 18. By using the screw sleeve 18 at one end of the clamping block 104, the clamping block 104 can be threadedly connected to the second screw rod 109.

[0028] Reference Figure 3 , inserting posts 92 are fixedly connected to the lower end of the extrusion die 9 at equal angles. The extrusion die 9 is inserted into the upper end of the rotating disk 8 through the inserting posts. By using the inserting posts 92 at the lower end of the extrusion die 9, it is convenient to insert and connect the lower end of the extrusion die 9 to the upper end of the rotating disk 8.

[0029] Reference Figure 2, a guiding mark 12 is fixedly installed on the front surface of the adjusting seat 604, and a scale sticker 13 is adhered to the outer side of the mounting bracket 601. By matching the guiding mark 12 on the adjusting seat 604 with the scale sticker 13, it is convenient for users to quickly complete the adjustment of the extrusion head 7 and the forming cavity 91 of the corresponding extrusion die 9; the position on the scale sticker 13 can be set and made in advance before leaving the factory. In this way, after the product leaves the factory, users can directly complete the adjustment of the extrusion head 7 by matching the guiding mark 12 on the adjusting seat 604 with the scale sticker 13 at the corresponding indicating position according to the replacement of the forming cavity 91 of different types of extrusion dies 9; the position of the guiding mark 12 corresponds to the position of the center of the extrusion head 7.

[0030] Reference Figure 2 , sliding columns 11 are symmetrically and fixedly installed on the inner side of the mounting bracket 601. The adjusting seat 604 is slidably connected to the outer side of the sliding columns 11. The upper end of the adjusting seat 604 and the inner side of the lower end of the mounting bracket 601 are slidably connected. By using the sliding columns 11 on the mounting bracket 601, the adjusting seat 604 can slide on the mounting bracket 601, and the upper end of the adjusting seat 604 slides on the inner side of the lower end of the mounting bracket 601, which can ensure the bearing effect of the adjusting seat 604. At the same time, it also ensures the force application effect and stability of the adjusting seat 604 on the extrusion head 7 when the output end of the air cylinder 5 pushes.

[0031] Principle and advantages of use: During the process of processing aluminum materials with different specifications of extrusion dies 9 according to production requirements, first, the extrusion die 9 needs to be replaced. By operating the second rotating handle 101 in the reverse direction, indirectly separating the clamping block 104 from the clamping groove 15 of the extrusion die 9, it is convenient to remove the extrusion die 9 from the rotating disk 8 for replacement. Then, the extrusion die 9 and the mounting block 103 are inserted, and at the same time, the lower end of the extrusion die 9 is inserted into the upper end of the rotating disk 8. After insertion, the position of the clamping block 104 corresponds to the position of the clamping groove 15 at this time. Then, operate the second rotating handle 101 to make the second rotating handle 101 rotate the rotating rod 102. At the same time, the first bevel gear 106 at the lower end of the rotating rod 102 meshes and drives the four second bevel gears 107 to rotate. The second screw rod 109 connected to the second bevel gear 107 can rotate inside the moving groove 108. Due to the rotation of the second screw rod 109, the clamping block 104 threadedly connected to the outside can slide and expand inside the moving groove 108. When the clamping end of the clamping block 104 extends out of the moving groove 108, it can be clamped into the corresponding clamping groove 15 to complete the fixation of the extrusion die 9;

[0032] When using different extrusion dies 9, the extrusion head 7 is connected to the adjusting seat 604 in a threaded form, which facilitates the replacement of the extrusion head 7 according to different extrusion dies 9. Secondly, during the use process, the first screw 602 is rotated on the mounting bracket 601 by turning the first handle 603, so that the adjusting seat 604 threadedly connected to the outer side of the second screw 109 slides on the mounting bracket 601. At this time, in combination with the guide mark 12 on the adjusting seat 604 cooperating with the scale sticker 13, it is convenient to adjust the extrusion head 7 according to the position of the forming cavity 91 of the extrusion die 9.
