[0038] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.
[0039] like Figure 1-10 As shown, the extrusion machine includes a base 1; it also includes: an extrusion mechanism 5, which is disposed above the base 1 and has an adjustable diameter extrusion cone at its bottom; a transfer mechanism 6, which is mounted on the base 1 and is located below the extrusion cone, and a gripping mechanism 4 is mounted above the transfer mechanism 6; the gripping mechanism 4 has multiple clamping parts; and a lifting mechanism 7, which is disposed inside the base 1 and is located below the extrusion mechanism 5.
[0040] The gripping mechanism 4 includes two carriers 401; the bottom of the two carriers 401 is connected to the top of the conveyor belts 605 of the two sets of conveying parts, and an electric cylinder 404 is fixedly installed on each of the two carriers 401. A movable frame 402 is fixedly connected to the output end of each of the two electric cylinders 404, and multiple sets of clamping parts are arranged between the two movable frames 402.
[0041] The clamping part consists of four wheels 403, and the four wheels 403 are arranged in pairs. The two pairs of wheels 403 are elastically installed to the inside of the two movable frames 402 respectively.
[0042] In specific implementation, a bearing surface is provided on the top surface of the machine base 1, which is used to place the workpiece 9. In order to make the top of the machine base 1 have a sufficient bearing surface for placing the workpiece 9 along the conveying direction of the transfer mechanism 6, additional plates are provided at the front and rear positions of the machine table, and the top surface of the plates is flush with the top surface of the bearing surface.
[0043] Initially, the workpiece 9 is clamped by the gripping mechanism 4. The electric cylinder 404 is initially in the retracted state, and the distance between the two movable frames 402 is at its maximum value. Multiple workpieces 9 to be processed are placed in multiple clamping parts, and the bearing surface supports the bottom of the workpiece 9. As the electric cylinder 404 extends, the two movable frames 402 move closer, and the two sets of wheels 403 press against the two side walls of the workpiece 9 to achieve clamping.
[0044] The transfer mechanism 6 includes a first motor 607, a first rotating shaft 601, and a second rotating shaft 602. The first rotating shaft 601 and the second rotating shaft 602 are both rotatably mounted in the base 1. Two sets of conveying parts are mounted on the first rotating shaft 601 and the second rotating shaft 602. A third pulley 606 is fixedly sleeved on the first rotating shaft 601. The first motor 607 is fixedly mounted in the base 1. A fourth pulley 608 is fixedly sleeved on the output shaft of the first motor 607. A transmission belt 609 is wound between the third pulley 606 and the fourth pulley 608.
[0045] The conveying unit includes a first pulley 603 and a second pulley 604. The first pulley 603 and the second pulley 604 are respectively fixedly sleeved on the first rotating shaft 601 and the second rotating shaft 602, and a conveyor belt 605 is wound between the first pulley 603 and the second pulley 604.
[0046] A guide rail 8 is mounted on the top of the base 1, and the guide rail 8 is slidably connected to the guide groove provided on the carrier 401.
[0047] After the workpiece 9 is clamped, the first motor 607 drives the fourth pulley 608 to rotate. Through the transmission belt 609, the third pulley 606, the first rotating shaft 601 and the first pulley 603 rotate together. In conjunction with the second rotating shaft 602 and the second pulley 604 on the second rotating shaft 602, the conveyor belt 605 moves. The conveyor belt 605 drives the carrier 401 of the gripping mechanism 4 to move, so that a workpiece 9 moves to below the expanding mechanism 5 and is located below the lifting mechanism 7.
[0048] When the lifting mechanism 7 is not lifting, the top surface of the tray 701 of the lifting mechanism 7 is part of the top bearing surface of the base 1, on which the supporting workpiece 9 can be placed.
[0049] The expansion mechanism 5 includes an outer cylinder 501 fixedly connected to the top plate 3; a connecting column 502 is fixedly installed at the axial position inside the outer cylinder 501, and the bottom end of the connecting column 502 is connected to the expansion cone.
[0050] The bottom of the expansion cone is an inverted frustum shape; the expansion cone includes expansion blocks 503, which are arranged in a ring array to the bottom of the connecting column 502, and a hydraulic cylinder 504 is installed between the inner side of the expansion blocks 503 and the connecting column 502.
[0051] The diameter of the expanding cone is adjusted according to the diameter of the workpiece 9. The expansion block 503 is moved by the extension and retraction of the hydraulic cylinder 504 to achieve the adjustment of the diameter of the expanding cone.
[0052] The lifting mechanism 7 includes a guide seat 703 and a second motor 706; both the guide seat 703 and the second motor 706 are fixedly installed inside the base 1; a sliding groove is provided on one side of the guide seat 703, and a vertically arranged slide bar 702 is slidably connected to the sliding groove; a rack 704 is provided on one side of the slide bar 702, and a gear 705 is meshed with the rack 704; the gear 705 is connected to the output shaft of the second motor 706; a tray 701 is fixedly installed on the top of the rack 704.
[0053] Before lifting the workpiece 9, the electric cylinder 404 retracts to cancel the clamping. Then, the second motor 706 drives the gear 705 to rotate. Through the meshing of the gear 705 and the rack 704, and with the guidance of the slide groove and the slide bar 702, the pallet 701 pushes the workpiece 9 above it to move upward. The expansion cone passes through the inside of the workpiece 9 to complete the rounding.
[0054] After the workpiece is rounded, the hydraulic cylinder 504 contracts, the diameter of the expansion cone decreases, becoming smaller than the inner diameter of the workpiece 9 after rounding. Then, the pallet 701 is driven to move downward until the pallet 701 is flush with the bearing surface of the top of the machine base 1. Then, the gripping mechanism 4 re-clamps all the workpieces 9.
[0055] Repeat the above operation to move the next workpiece 9 to be processed onto the lifting mechanism 7, cancel the clamping of workpiece 9, then adjust the diameter of the expanding cone, the lifting mechanism 7 lifts the workpiece 9, and completes the rounding through the expanding cone. The expanding cone is adjusted to be smaller than the inner diameter of the workpiece 9, and the lifting mechanism 7 drives the workpiece 9 back to the bearing surface at the top of the machine base 1. By repeating the above operation, the processing of all workpieces 9 is completed, and finally all workpieces 9 are removed.
[0056] Support columns 2 are fixedly installed around the base 1, and a top plate 3 is fixedly connected to the top of the support columns 2; the expansion mechanism 5 is installed on the top plate 3.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
