Description

Technical Field

[0001] This utility model relates to an extrusion press, specifically a high-efficiency metal processing extrusion press. Background Technology

[0002] In the field of metal processing, extrusion presses are the core equipment for forming metal profiles, pipes, and other products, and are widely used in the processing and production of metal materials such as aluminum, copper, magnesium, and their alloys. Their working principle mainly involves using the thrust of the extrusion shaft to force a heated metal billet to a plastic state into a die with specific orifices. This causes the metal billet to undergo plastic deformation under the constraint of the die, ultimately extruding it into a metal product conforming to a preset cross-sectional shape.

[0003] However, the level of automation in the billet feeding stage of existing metal processing extrusion presses is still relatively low. Even if some equipment is equipped with basic conveying mechanisms, a lot of manual intervention is still required, which seriously restricts the improvement of production efficiency and processing stability.

The drive assembly includes a mounting plate 72, a lead screw 73, a screw sleeve 74, and a motor 75. There are two mounting plates 72, which are fixedly connected to the two ends of the base 71 along its length. The lead screw 73 is rotatably connected between the two mounting plates 72. One end of the lead screw 73 is fixedly connected to the output end of the motor 75. The motor 75 is fixedly connected to the mounting plate 72. A screw sleeve 74 (not shown in the figure) is threaded onto the lead screw 73. The bottom surface of the screw sleeve 74 is slidably connected to the base 71. The feeding assembly is fixedly connected to the top surface of the screw sleeve 74.

[0026] The feeding assembly includes a moving frame 76, a first cylinder 77, a base plate 78, a side plate 79, and rollers 710. The moving frame 76 is fixedly connected to the threaded sleeve 74. The first cylinder 77 is vertically installed on the side of the moving frame 76 near the base frame. The output end of the first cylinder 77 is fixedly connected to the base plate 78. The two sides of the base plate 78 are fixedly connected to the side plates 79 respectively. Multiple rollers 710 are rotatably connected to the surfaces of the base plate 78 and the side plates 79. The rollers 710 facilitate the movement of the billet.

[0027] Two sets of guide rails 711 are provided on opposite sides of the lead screw 73. The guide rails 711 are fixedly connected to the base 71. The bottom surface of the movable frame 76, which is opposite to the two sets of guide rails 711, is provided with a sliding groove 712. The guide rails 711 and the sliding groove 712 are slidably connected.

[0028] Guide rods 713 are provided at both ends of the bottom surface of the base plate 78. The lower end of the guide rods 713 passes through the movable frame 76 and is slidably connected to it.

[0029] The extrusion rod mechanism 6 includes a connecting plate 61, a limiting plate 62, a connecting block 63, an extrusion rod body 64, and a second hydraulic cylinder 65. The connecting plate 61 is slidably connected to the support column 3. Two limiting plates 62 are provided on the side of the connecting plate 61 near the extrusion cylinder mechanism 5. The two limiting plates 62 are vertically fixedly connected to the connecting plate 61 with each other. The connecting block 63 is disposed between the two limiting plates 62, and its upper and lower surfaces are slidably connected to the two limiting plates 62. The extrusion rod body 64 is fixedly connected to the side of the connecting block 63 near the extrusion cylinder mechanism 5. The second hydraulic cylinder 65 is mounted on the second mounting base 2, and the output end of the second hydraulic cylinder 65 is fixedly connected to the connecting plate 61.

[0030] The obstacle avoidance mechanism 8 includes a fixed plate 81 and a second cylinder 82. The fixed plate 81 is located on the side of the connecting block 63 near the feeding mechanism 7.

[0031] The pushing mechanism 9 is a first hydraulic cylinder 91 located on the side of the connecting block 63 near the feeding mechanism 7. When the second cylinder 82 of the avoidance mechanism 8 pushes the connecting block 63 and the extrusion rod body 64 to make way for the billet of the feeding mechanism 7, the axis of the first hydraulic cylinder 91 on the connecting block 63 is opposite to the feed port axis of the extrusion cylinder mechanism 5. That is, the pushing distance of the second cylinder 82 is equal to the vertical distance between the axis of the first hydraulic cylinder 91 and the axis of the extrusion cylinder mechanism 5.

[0032] The extrusion cylinder mechanism 5 is used to place the billet and includes an extrusion cylinder body 51 and a third hydraulic cylinder 52.

The output end of the third hydraulic cylinder 52 is fixedly connected to the extrusion cylinder body 51.

[0033] The working principle of this utility model is as follows: In the initial state, the feeding mechanism 7 is in the initial position, and the extrusion rod body 64 of the extrusion rod mechanism 6 is coaxially aligned with the extrusion cylinder body 51 of the extrusion cylinder mechanism 5. During processing, the preheated billet is conveyed to the base plate 78 of the feeding assembly via the conveying mechanism, and the side plates 79 on both sides limit the billet. Subsequently, the motor 75 of the drive assembly starts, driving the lead screw 73 to rotate, causing the screw sleeve 74 to slide along the base 71. At the same time, the moving frame 76 moves synchronously along the guide rail 711 through the slide groove 712, conveying the billet to the feeding position between the extrusion cylinder mechanism 5 and the extrusion rod mechanism 6. Simultaneously, the second cylinder 82 of the avoidance mechanism 8 starts, pushing the connecting block 63 to slide along the two limit plates 62, causing the extrusion rod body 64 to deviate from the axis of the extrusion cylinder body 51, making way for the billet, until the axis of the first hydraulic cylinder 91 on the connecting block 63 is aligned with the feed port axis of the extrusion cylinder body 51. Subsequently, the first hydraulic cylinder 91 of the pushing mechanism 9 is activated, pushing the billet along the roller 710 into the extrusion cylinder body 51. Next, the first cylinder 77 of the feeding assembly retracts, guiding the bottom plate 78 downwards via the guide rod 713, preventing interference between the feeding assembly and the first hydraulic cylinder 91 during resetting. Afterwards, the first hydraulic cylinder 91 resets, and the feeding mechanism 7 returns to its initial position driven by the motor 75. Simultaneously, the second cylinder 82 resets, and the connecting block 63 drives the extrusion rod body 64 back to a position coaxial with the extrusion cylinder body 51. Finally, the second hydraulic cylinder 65 pushes the connecting plate 61 to slide along the support column 3, advancing the extrusion rod body 64 into the extrusion cylinder body 51. This, combined with the movement of the extrusion cylinder body 51 towards the mold assembly 4 driven by the third hydraulic cylinder 52, completes the billet extrusion molding operation.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
