Description

TECHNICAL FIELD

[0001] The utility model belongs to the main shaft machining technical field, specifically relates to a press for machining main shaft. BACKGROUND

[0002] In the modern mechanical manufacturing field, the main shaft as the key parts of various mechanical equipment, its processing quality and efficiency directly affect the performance and production benefit of the whole equipment. In the machining process of the main shaft, the application of the press is very important.

[0003] The traditional press for machining main shaft has many deficiencies in practical application. First, from the structure design aspect, most are relatively simple, and the function is single. When the main shaft forge piece is processed, the platform bearing the forge piece is usually a simple flat plate, lacks targeted design and optimization, and is difficult to meet the complex processing demand.

[0004] In the processing technology aspect, when the traditional press is used to press forge the main shaft forge piece, it can only operate face by face. When one face forging is completed, the forge piece needs to be manually turned over, and then the forging of the next face is carried out. This manual turning over method not only has extremely low efficiency, but also has great labor intensity. Due to the uncertainty of manual operation, the turning over is also prone to inaccuracy, which affects the subsequent machining precision.

[0005] In the impurity treatment aspect, due to the lack of effective impurity removal mechanism, the oxidation layer, debris and other impurities generated on the surface of the forge piece due to the great pressure and friction force in the forging process will scatter everywhere. These impurities not only pollute the working environment, increase the difficulty and cost of cleaning work, but also may mix into the forge piece being processed, causing quality problems such as surface damage and size deviation of the forge piece, which seriously affects the machining quality and service life of the main shaft.

[0006] Therefore, we propose a press for machining main shaft, which can automatically complete the turning over of the forge piece, improve the working efficiency, and timely remove the impurities to ensure the machining quality. CONTENT OF THE UTILITY MODEL

[0007] The utility model aims at providing a press for machining main shaft, which can automatically complete the turning over of the forge piece, improve the working efficiency, and timely remove the impurities to ensure the machining quality.

[0018] The utility model achieves the following technical effects:

[0019] Before the machining process of the main shaft starts, the forging needs to be treated by heating to reach a suitable temperature and material performance for forging, the forging heated to a high temperature and appearing in a red state is taken out from the heating equipment and accurately placed on the bearing plate of the press machine, preparing for the subsequent press forging, starting the hydraulic assembly on the support plate, which generates strong pressure on the forging, causing plastic deformation of the forging and achieving the purpose of forging. During the press process, the surface of the forging will fall off the oxidation layer, debris and other impurities due to the huge pressure and friction, and since the surface of the bearing plate and the surface of the bearing plate are closely attached, the falling impurities cannot scatter everywhere, but follow the guide of the impurity removal plate and fall on one side of the bearing plate. When one side of the forging completes the press forging, the hydraulic assembly stops applying pressure and retracts to the initial position, and the rotating assembly is used to move the two rotating assemblies close to each other to clamp the forging from opposite directions, fixing the forging for subsequent operation, and the telescopic assembly is used to adjust the height position of the rotating assembly and the clamped forging. Then, the rotating assembly starts to rotate to change the orientation of the forging and adjust the un-forged side to a suitable position for press forging, preparing for the next press forging. When the rotating assembly moves relative to the rotating assembly, the first wedge block is pushed. The movement of the first wedge block will squeeze the second wedge block attached to it, and then the impurity removal plate will move under the drive of the second wedge block and the cooperation of the elastic assembly, removing the impurities accumulated on one side to keep the working area clean and avoid interference with subsequent processing. The device can automatically complete the turning of the forging, improve the work efficiency, and timely remove the impurities to ensure the processing quality. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0026] In order to make the purpose and advantages of the present utility more clear and explicit, the following will specifically describe the present utility with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the present utility, and does not strictly limit the scope of protection specifically requested by the present utility.

[0027] As Figures 1-4 shown, the technical scheme adopted by the present utility is as follows: a press machine for machining main shaft, comprising a bottom plate 1, the top of the bottom plate 1 is provided with four stand columns 2 and a bearing plate 3 for bearing the main shaft forging, the top of the four stand columns 2 is provided with a support plate 4, and the support plate 4 is provided with a hydraulic assembly;

[0028] The upper surface of the bottom plate 1 is provided with two first sliding grooves 5 and two second sliding grooves 6, the inside of the two first sliding grooves 5 is provided with a rotating assembly, the rotating assembly is provided with a first wedge 7, the top of the first wedge 7 is provided with an extension assembly, the top of the extension assembly is provided with a first connecting plate 8, and the first connecting plate 8 is provided with a rotating assembly;

[0029] The inside of each second sliding groove 6 is provided with an elastic moving assembly, the elastic moving assembly is provided with an impurity removal plate 9 which is attached to the surface of the bearing plate 3, the two ends of the impurity removal plate 9 are provided with a second wedge 10 which is attached to the first wedge 7, and the two impurity removal plates 9 and the four second wedges 10 form a frame which is attached to the four surfaces of the bearing plate 3.

[0030] Its working principle is as follows: Before the machining process of the spindle begins, the forging needs to be heated to achieve a suitable temperature and material properties for forging. The forging, heated to a high temperature and red-hot, is taken out of the heating equipment and accurately placed on the bearing plate 3 of the press, preparing for subsequent pressure forging. The hydraulic components on the support plate 4 are activated, generating strong pressure that acts on the forging, causing plastic deformation and achieving the forging purpose. During the pressurization process, due to the enormous pressure and friction on the forging, the oxide layer, debris, and other impurities on its surface will fall off. Because the impurity removal plate 9 is in close contact with the surface of the bearing plate 3, the fallen impurities cannot scatter everywhere, but are guided by the impurity removal plate 9 and fall to one side of the bearing plate 3. When one side of the forging has been pressurized, the hydraulic components stop applying pressure and retract to the initial position. Using the movement of the rotating components, the two rotating components move closer to each other, clamping the forging from opposite directions to fix the forging for subsequent operations. The telescopic components extend and retract to adjust the height position of the rotating components and the clamped forging. Next, the rotating assembly begins to rotate, changing the orientation of the forging and adjusting the unforged surface to a suitable position for pressure application, preparing for the next pressure forging. As the rotating assembly moves relative to the other component, it simultaneously pushes the first wedge block 7. The movement of the first wedge block 7 compresses the second wedge block 10, which in turn causes the impurity removal plate 9 to move under the influence of the second wedge block 10 and the elastic assembly, removing impurities accumulated on one side to maintain a clean working area and prevent impurities from interfering with subsequent processing. This device can automatically flip the forging, improving work efficiency and ensuring processing quality by promptly removing impurities.

[0031] The hydraulic assembly includes a hydraulic cylinder 11 mounted on a support plate 4. A hydraulic rod is mounted on the telescopic end of the hydraulic cylinder 11, and the bottom of the hydraulic rod passes through the support plate 4 and is fitted with a hydraulic head 12.

[0032] The hydraulic cylinder 11 drives the hydraulic rod to extend and retract, thereby driving the hydraulic head 12 to pressurize and forge the main shaft forging.

[0033] Meanwhile, the rotating assembly includes a first motor 13 mounted on the base plate 1. A rotating rod 14 is mounted on the output end of the first motor 13. The end of the rotating rod 14 away from the first motor 13 passes through the base plate 1 and is located inside the first slide groove 5. The rotating rod 14 is provided with opposite threads, and a threaded sleeve 15 is fitted on the opposite threads. The top of the threaded sleeve 15 is connected to the first wedge block 7.

[0034] The first motor 13 drives the rotating rod 14 to rotate, and the rotating rod 14 drives the two threaded sleeves 15 to move in opposite or opposite directions.

[0035] Further, two opposite threads are respectively arranged in the two first sliding grooves 5, so that the threaded sleeve 15 is driven to move in the first sliding grooves 5 under the action of the threads.

[0036] The telescopic assembly comprises an electric telescopic rod 16 arranged on the top of the first wedge-shaped block 7, and the top of the electric telescopic rod 16 is connected with the first connecting plate 8. The height of the rotating assembly is adjusted by the first electric telescopic rod 16, so that the subsequent rotation of the forging is facilitated.

[0037] The rotating assembly comprises a second motor 17 arranged on the first connecting plate 8, and a rotating shaft is arranged on the output end of the second motor 17. The end of the rotating shaft away from the second motor 17 penetrates through the first connecting plate 8 and is provided with a fixed disc 18.

[0038] When the rotating shaft is driven by the second motor 17, the fixed disc 18 drives the main shaft to rotate and turn over the forging.

[0039] Further, the fixed disc 18 is made of high-temperature-resistant metal, so that it has the effect of resisting high temperature, and is provided with an anti-skid surface. The anti-skid surface can prevent sliding when the forging is fixed.

[0040] The elastic moving assembly comprises a fixed shaft 19 arranged in the second sliding groove 6, a sliding block 20 and a spring 21 are arranged on the fixed shaft 19, one side of the sliding block 20 is connected with the spring 21, and a connecting rod is arranged on the top of the sliding block 20. One side of the connecting rod is connected with the impurity removal plate 9.

[0041] When the impurity removal plate 9 moves, the connecting rod drives the sliding block 20 to move on the fixed shaft 19 and press the spring 21, so as to achieve the effect of moving and removing impurities.

[0042] In order to enable the impurities to quickly fall on one side of the impurity removal plate 9, an inclined sliding surface 22 is arranged on the impurity removal plate 9. The inclined sliding surface 22 can enable the impurities to quickly flow to one side of the impurity removal plate 9.

[0043] A first sealing plate is arranged on one side of the first wedge-shaped block 7, and a second sealing plate is arranged on one side of the connecting rod. The first sealing plate can seal the first sliding groove 5, and the second sealing plate can seal the second sliding groove 6. In this way, the impurities can be prevented from entering the first sliding groove 5 and the second sliding groove 6.

During the pressurizing process, the surface of the forging will fall off the oxidation layer, debris and other impurities due to the huge pressure and friction, and since the impurity removal plate 9 is closely attached to the surface of the bearing plate 3, the falling impurities cannot scatter everywhere but follow the guide of the impurity removal plate 9 and fall on one side of the bearing plate 3, when one side of the forging completes the press forging, the hydraulic assembly stops applying pressure and retracts to the initial position, the two rotating assemblies are brought close to each other by the action of the rotating assembly to clamp the forging from opposite directions to fix the forging for subsequent operation, the telescopic assembly performs the telescopic action to adjust the height position of the rotating assembly and the clamped forging. Then, the rotating assembly starts to rotate to change the orientation of the forging, adjust the side that has not been forged to a suitable position for pressurizing to prepare for the next press forging, when the rotating assembly drives the rotating assembly to move relatively, the first wedge 7 will be pushed at the same time. The movement of the first wedge 7 will squeeze the second wedge 10 attached thereto, and then make the impurity removal plate 9 move under the drive of the second wedge 10 and the cooperation of the elastic assembly to remove the impurities accumulated on one side to keep the working area clean and avoid interference of the impurities to subsequent processing. The device can automatically complete the turning of the forging, improve the work efficiency, and at the same time, can remove the impurities in time to ensure the processing quality.
