Description

Technical Field

[0001] The present invention belongs to the technical field of automatic cleaning, and particularly relates to an automatic cleaning device for the movable pad of a copper extrusion press. Background Technique

[0002] The extrusion pad is an important tool in extrusion production that directly contacts the billet. In copper extrusion production, due to the easy oxidation of copper alloys at high temperatures, the method of shelling extrusion is usually adopted. Therefore, in each extrusion cycle, it is necessary to clean the metal residues on the surface of the extrusion chamber and the extrusion pad.

[0003] The movable pad to be cleaned usually has a dense metal oxide layer wrapped around its circumferential surface, and its two ends are respectively adhered with the press residue (the remaining material that has not been extruded) and the shelling in a compressed state. The oxide layer is relatively hard and tightly covers the circumferential surface of the movable pad, making it difficult to clean. In the actual production process, manual or semi-manual cleaning is usually adopted. First, a simple device is used to cut off the press residue and shelling at both ends of the pad, and then it is transferred to another place for manual cleaning of the circumferential surface of the movable pad. This cleaning method not only takes a long time, has poor cleaning effect and low production efficiency, but also has a large labor intensity for workers and is somewhat dangerous in the face of high-temperature metal debris. If the movable pad is not cleaned in time, it will affect the production rhythm of the entire press. Summary of the Invention

[0044] Furthermore, in the automatic cleaning device for the movable pad of the copper extrusion press of the present invention, the upper assembly 31 includes a pad end face surplus shearing edge 311, an end face shelling shearing edge 312, a circumferential oxidation layer breaking and shelling shearing edge 313, a shearing edge driving oil cylinder 314, two guiding mechanisms 315, and a movable suspension device 316.

The two guiding mechanisms 315 are symmetrically installed on both sides of the circumferential oxidation layer breaking and shelling shearing edge 313. The guiding mechanism 315 is slidably connected to the upper seat 11. The output end of the shearing edge driving oil cylinder 314 is connected to the circumferential oxidation layer breaking and shelling shearing edge 313.

[0045] Furthermore, in the automatic cleaning device for the movable pad of the copper extrusion press of the present invention, the lower assembly 32 includes a V-shaped workbench 321, a workbench driving oil cylinder 322, and a guiding rod 323. The guiding rod 323 is fixedly installed on the lower seat 12. The V-shaped workbench 321 is installed at the top of the guiding rod 323. The output end of the workbench driving oil cylinder 322 is connected to the end of the guiding rod 323. When the movable pad 600 is placed on the V-shaped workbench 321, the lower assembly 32, the circumferential oxidation layer breaking and shelling shearing edge 313, the shearing edge driving oil cylinder 314, and the guiding mechanism 315 can rise or fall simultaneously, thereby realizing automatic cleaning of the waste materials at both ends of the movable pad 600.

[0046] Furthermore, in the automatic cleaning device for the movable pad of the copper extruder of the present invention, the material turning mechanism 51 includes a turning plate 511, a turning plate rotating shaft 512, a turning driving cylinder 513 and a mounting seat 514. The mounting seat 514 is arranged on one side of the prestressed frame 1 and fixed to the tie rod 13. The turning driving cylinder 513 is installed on the mounting seat 514. The turning plate rotating shaft 512 is fixedly connected to the turning plate 511. One end of the turning plate rotating shaft 512 is rotationally connected to the output shaft of the turning driving cylinder 513, so that the waste materials to be cleaned can be collected in a timely and effective manner.

[0047] Furthermore, in the automatic cleaning device for the movable pad of the copper extruder of the present invention, the distance between the cutting edges of the pad end face surplus shear edge 311 and the end face shelling shear edge 312 is greater than the thickness of the movable pad 600 by about 0.5 - 1 mm, so as to effectively ensure that the movable pad 600 will not be damaged when cutting the waste materials.

[0048] Furthermore, in the automatic cleaning device for the movable pad of the copper extruder of the present invention, the number of receiving troughs 52 is four, and the receiving troughs 52 are arranged in a circumferential pattern around the V-shaped workbench 321, so as to effectively ensure that the waste materials falling from multiple directions can be completely collected into the receiving troughs.

[0049] Specifically, firstly, the movable pad 600 to be cleaned is moved horizontally to the top of the V-shaped workbench 321 through the horizontal clamping and conveying mechanism 2. After the V-shaped workbench 321 is raised to the position to receive the movable pad 600 through the workbench driving cylinder 322, the shelling shearing blade 313 for breaking the circumferential oxide layer is lowered until it contacts the movable pad 600 and a certain pressure is applied to the contact part, thereby completing the first breaking of the oxide layer on the circumferential surface of the movable pad 600. Under the action of the arm driving cylinder 42, the cleaning claw 411 at the front end of the pad circumferential surface cleaning mechanism 4 contacts the circumferential surface of the movable pad 600 and maintains a certain force. The workbench driving cylinder 322 in the lower seat 12 rises, driving the movable pad 600 on the V-shaped workbench 321 to rise, and the end face of the movable pad 600 is sequentially entered into the pad end face shearing mechanism 3 until the waste materials at both ends of the movable pad 600 are removed. In this process, the claws of the pad circumferential surface cleaning mechanism 4 also complete the peeling of the upper part of the circumferential surface of the movable pad 600. After the movable pad 600 reaches the highest position, the pad suspension device is activated and the workbench descends to the lowest position. The pad circumferential surface cleaning mechanism 4 is activated again to complete the peeling of the lower part of the circumferential surface of the movable pad 600. At this point, the movable pad is cleaned. The peeled oxide scale and waste material fall into the receiving trough 52 in the lower seat 12. For the oxide scale remaining on the workbench, the two sets of flip driving cylinders 513 drive the flap 511 to rotate and sweep across the V-shaped workbench 321 to a horizontal position, and the oxide scale in the workbench is transferred to the flap 511. The scraper 53 installed on the first transmission frame 222 in the first horizontal transverse mechanism 22 pushes the oxide scale into the receiving trough 52. The V-shaped workbench 321 rises again and receives the movable pad 600. When the workbench descends to the lower position, the horizontal clamping and conveying mechanism 2 clamps the movable pad 600 and rotates it slowly around its axis. The circumferential surface of the movable pad 600 can be lubricated by cooperating with the lubrication system, and then the movable pad 600 is moved out of the cleaning device.

[0050] In summary, compared with the prior art, the automatic cleaning device for the movable pad of a copper extruder of the present invention has the following advantages and beneficial effects: the automatic cleaning device for the movable pad of a copper extruder is efficient, fast, and of high quality in the cleaning process of metal waste at the two ends and the circumferential surface of the movable pad. The movable pad is clamped by a horizontal clamping and transferring mechanism, which effectively reduces the potential safety hazards during the cleaning process. The oxide layer waste collection mechanism is used to clean and collect the removed waste, thereby achieving complete automation.
