Description

Technical Field

[0001] The present application relates to the technical field of light metal forming manufacturing equipment and methods, and in particular to a complete set of equipment for deformation extrusion forming of light metals. Background Art

[0002] Light metal generally refers to a density less than 4.5g / cm 3 Metals include aluminum (Al), magnesium (Mg), calcium (Ca), potassium (K), sodium (Na), strontium (Sr), barium (Ba), etc. In industry, the most widely used light metals are aluminum and magnesium. These light metals and their alloys have the characteristics of low density, high specific strength, good thermal conductivity and electrical conductivity, and have important applications in many fields such as aerospace, automobiles, and electronics. Among them, magnesium is a key light metal, and its magnesium alloy materials are also widely used in various industrial fields.

[0003] The extrusion deformation process of magnesium alloy mainly includes the following steps: (1) Billet cutting: Cut the magnesium alloy ingot into billets of suitable size. The length and diameter (for round billets) of the billets need to be determined according to the specifications of the extruder and the size of the required extruded product; (2) Billet heating: The magnesium alloy billet needs to be heated to a suitable temperature range before extrusion. Common heating methods include resistance furnace heating, induction heating, etc.; (3) Extrusion molding: Put the heated and lubricated billet into the extrusion barrel. The extrusion barrel usually has high strength and hardness to withstand the high pressure during the extrusion process. The billet is pressed by the extrusion rod to cause the billet to undergo plastic deformation in the extrusion barrel. The billet passes through the die hole of the die under pressure to obtain the desired shape and size; (4) Post-processing: The extruded magnesium alloy product needs to be cooled. Moreover, the cooled product may be bent or twisted to a certain extent and needs to be straightened to meet the dimensional accuracy requirements. At present, the device used for extrusion deformation of magnesium alloy usually presses the material downward through the extrusion cylinder and completes the forming process under the limitation of the mold. However, after the extrusion process is completed, the existing extrusion processing device needs to take out the profile or replace other molds. It usually sets a motor or a driving component to drive the fixed plate to rotate to a suitable position to complete the above work.

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

In the steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided in the embodiment of the present application.

[0029] refer to Figure 1-6As shown, the present application provides a complete set of deformation extrusion forming equipment for light metal, including: a base plate 11, a support plate 12, a guide rod 13, a hydraulic cylinder 21, an extrusion plate 22, a fixed plate 31, a support plate 32, a cylinder 41, and a turntable 42.

[0030] The guide rod 13 is fixedly arranged on the base plate 11 in the vertical direction, the top of the guide rod 13 is fixedly connected to the support plate 12, the hydraulic cylinder 21 is fixedly arranged on the support plate 12, the output end of the hydraulic cylinder 21 is arranged in the vertical direction, the output end of the hydraulic cylinder 21 is connected to the extrusion plate 22, the extrusion plate 22 is provided with a through hole matching the guide rod 13, the output end of the hydraulic cylinder 21 is telescopically moved to drive the pressure plate to move in the vertical direction along the guide rod 13, wherein the guide rods 13 are respectively arranged at the corner ends of the base plate 11, and the movement stability of the extrusion plate 22 in the vertical direction is jointly realized by a plurality of vertically arranged guide rods 13.

[0031] A limiting sleeve 14 is provided on the guide rod 13 . The limiting sleeve 14 is provided in the vertical direction and is located below the extrusion plate 22 . The limiting sleeve 14 can limit the extrusion plate 22 when it moves downward, thereby preventing the extrusion plate 22 from being damaged due to excessive downward pressure.

[0032] The fixed plate 31 is fixedly connected to the bottom of the base plate 11, the rotating plate 42 is connected to the support plate 32, the support plate 32 is located below the extrusion plate 22, and the support plate 32 is used to support the mold. Specifically, a mounting seat 43 is fixedly arranged at the bottom of the rotating plate 42, the mounting seat 43 is fixedly connected to the support plate 32, and the mounting seat 43 and the support plate 32 are connected by a connecting member. Optionally, the connecting member is a component that can be fixedly connected to the mounting seat 43 and the support plate 32 respectively by fasteners, and then the rotating plate 42 is rotated to drive the fixed plate 31 and the support plate 32 to rotate together, so as to meet the needs of moving the mold or extruded processing materials carried on the support plate 32.

[0033] The cylinder 41 is disposed below the bottom plate 11 , and the output end of the cylinder 41 is connected to the adapter block 44 , which is rotatably connected to the turntable 42 . A connecting portion 45 is disposed on the outer edge of the turntable 42 , and the connecting portion 45 is rotatably connected to the adapter block 44 .

[0034] The turntable 42 is connected to the fixed plate 31, and the output end of the cylinder 41 is telescopically moved to drive the turntable 42 and the support plate 32 to rotate. The output end of the cylinder 41 is arranged in the horizontal direction, and the turntable 42 is driven to rotate by the telescopic movement of the output end of the cylinder 41.

[0035] The telescopic movement of the output end of the hydraulic cylinder 21 drives the pressure plate to move along the guide rod 13, and the pressure plate squeezes the material supported on the support plate 32. When the material or mold on the support plate 32 needs to be replaced, the output end of the driving cylinder 41 is controlled to move to drive the turntable 42 and the tray to rotate to the operating station and complete the above-mentioned working steps.

[0036] A slider 46 is provided at the bottom of the fixed disk 31, and a plurality of sliders 46 are spaced apart along the circumferential direction of the fixed disk 31. A first slide groove 421 and a second slide groove 422 are respectively provided on the turntable 42, and the first slide groove 421 and the second slide groove 422 are respectively spaced apart along the circumferential direction of the turntable 42. The sliders 46 are respectively connected to the first slide groove 421 and the second slide groove 422, and the cooperation between the slider 46 and the first slide groove 421 and the second slide groove 422 realizes the guiding effect of the turntable 42 during the rotation process, wherein the slider 46 is connected to the bottom of the fixed disk 31 through a fixing member.

[0037] The first slide groove 421 includes a straight segment 4213, a connecting end 4214, a first arc segment 4211, and a second arc segment 4212. The first slide groove 421 is formed by the straight segment 4213, the connecting end 4214, the first arc segment 4211, and the second arc segment 4212, wherein both ends of the straight segment 4213 are respectively connected to the connecting end 4214, the first arc segment 4211 is connected to the second arc segment 4212 and is located on the opposite side of the straight segment 4213, and the straight segment 4213 is parallel to the telescopic movement direction of the output end of the cylinder 41, thereby being able to stably cooperate with the movement direction of the output end of the cylinder 41 for guidance.

[0038] The first arc segment 4211 and the second arc segment 4212 are arranged closer to the center of the turntable 42 than the straight line segment 4213, and the end of the first arc segment 4211 and the end of the second arc segment 4212 are respectively connected to the connecting end 4214, and the first arc segment 4211 and the second arc segment 4212 form a protruding end 4215 at the connecting portion, and the protruding end 4215 is arranged toward the center of the turntable 42.

[0039] The curvature of the first arc segment 4211 is smaller than that of the second arc segment 4212, and the opening formed by the raised end 4215 faces the straight line segment 4213, so that when the side edge or wall surface of the slider 46 moves relatively along the first arc segment 4211 first, it moves along the first arc segment 4211 which is relatively gentle or has a smaller curvature, and when the side edge or wall surface of the slider 46 contacts the first arc segment 4211, it prevents the slider 46 and the first slide groove 421 from being worn out in the early stage of relative movement, thereby achieving smooth guidance. After the slider 46 moves relatively along the first slide groove 421 and passes through the raised end 4215, it can be guided by the second arc segment 4212 with a larger curvature, thereby ensuring that the slider 46 can be effectively guided at the end of the second arc segment 4212 and prevented from sliding.

[0040] The first slide groove 421 and the second slide groove 422 are arranged at intervals along the circumferential direction on the rotating disk 42. The first slide groove 421 includes a straight section 4213, a connecting end 4214, a first arc section 4211 and a second arc section 4212. A protruding end 4215 is formed at the connection between the first arc section 4211 and the second arc section 4212. Therefore, when the slider 46 moves in the first slide groove 421 through the protruding end 4215, the gap between the wall surface of the slider 46 and the inner wall of the first slide groove 421 can be increased to reduce the sliding The wear or jamming between the block 46 and the slide groove, the linear drive brought about by the telescopic movement of the output end of the cylinder 41 by the straight segment 4213, and the first arc segment 4211 and the second arc segment 4212 reasonably arranged on the opposite side of the straight segment 4213 can effectively guide the slider 46 and prevent the wear caused by continuous movement along a straight line in the first slide groove 421, as well as the side of the slider 46 in contact with the slide groove from being severely worn and having a gap, thereby affecting the rotation accuracy and stability of the turntable 42, thereby ensuring the working stability and reliability of the deformation extrusion equipment for light metals.

[0041] Furthermore, the material of the slider 46 arranged in the first slide groove 421 is metal material, optionally, the metal material is aluminum alloy, copper, etc., and the material of the slider 46 arranged in the second slide groove 422 is rubber material, thereby, the slider 46 in the first slide groove 421 can contact the first slide groove 421 with higher hardness and smaller deformation, so that the straight line segment 4213 can stably act on the slider 46 with higher strength and smaller deformation. The slider 46 in the second slide groove 422 is made of rubber material, which can increase the friction between the slider 46 and the inner wall of the second slide groove 422, while ensuring that the second slide groove 422 and the slider 46 are coordinated and guided, and the friction between the slider 46 and the second slide groove 422 is increased to ensure rotation stability.

[0042] The second slide groove 422 is an arc groove. Thus, the first slide groove 421 and the second slide groove 422, which are arranged at intervals, jointly realize the cooperation of the turntable 42 during the rotation process. The main purpose of the first slide groove 421 is to provide a clear motion path for the relative movement between the slider 46 and the first slide groove 421 through the straight line segment 4213, and in the process of driving the turntable 42 to rotate, combined with a suitable control algorithm, the distance of the linear motion can be used to accurately control the rotation angle of the turntable 42. By accurately calculating the relationship between the moving distance of the slider 46 in the linear slide groove and the rotation angle of the turntable 42, high-precision angle positioning can be achieved, which is very important for the process that requires precise angle control.

[0043] In addition, the output force of the cylinder 41 acts directly on the linear slideway through the slider 46, and the force transmission path is short and direct. Compared with some multi-stage transmission methods, the force loss in the transmission process can be reduced and the energy utilization efficiency can be improved. And because the force transmission is direct and the linear slideway can be designed to have sufficient strength, within a reasonable design range, this driving method can withstand a larger load.

[0044] The second slide groove 422 can ensure the stable guidance of the rotating disk 42 during the rotation process and prevent the rotating disk 42 from shaking significantly.

[0045] The controller and the control valve are also included. The controller is connected to the control valve. The controller drives the output end of the cylinder 41 through the control valve to extend the output end of the cylinder 41 at a first rate and then at a second rate. The first rate is less than the second rate. The control valve can control the gas flow rate proportionally according to the input electrical signal. By connecting to a control system, such as a PLC (programmable logic controller), the speed of the cylinder 41 can be dynamically adjusted according to various parameters in the production process.

[0046] Specifically, when the output end of the cylinder 41 extends at a first rate, the slider 46 moves along the first arc segment 4211 in the first slide groove 421, and when the output end of the cylinder 41 extends at a second rate, the slider 46 moves along the second arc segment 4212 in the first slide groove 421. Thus, the slider 46 can move at a lower speed at the front end of the first slide groove 421, thereby ensuring the stability of the movement and moving in coordination with the first arc segment 4211 with a smaller curvature, and after passing the protruding end 4215, the slider 46 moves at a higher second rate to move in coordination with the second arc segment 4212 with a larger curvature to effectively achieve the stability of the cooperation between the slider 46 and the end of the first slide groove 421 and achieve effective guidance.
