Description

Technical Field

[0001] The invention belongs to the technical field of industrial production, and in particular relates to a special movable workbench for an isothermal forging hydraulic press. Background Art

[0002] With the development of aerospace industry, the size specifications of high-temperature isothermal forging parts of aluminum alloy, titanium alloy and other products are getting larger and larger, the corresponding isothermal forging heating furnace and mold size and height are also getting larger and larger, the required temperature for workpiece forming is also getting higher and higher, and because of the requirements for thermal insulation, the height of the mobile table of the supporting hydraulic press needs to be reduced as much as possible to meet the best operating requirements of ergonomics. Sufficient space is reserved in front of, behind, left and right of the workbench for the installation of thermal insulation devices, and the fire hazard caused by the use of hydraulic oil in the hydraulic cylinder drive is avoided. The mobile table drive modes of conventional hydraulic presses include self-moving, traction and cylinder drive.

[0003] The self-moving mobile workbench usually installs the reducer under the mobile table panel. Due to the installation space requirements of the reducer, the height of the workbench needs to be relatively high. The height of the workbench superimposed on the height of the heating furnace and the mold is inconvenient for the operator to operate and does not meet the ergonomic requirements. It is necessary to add a shoulder step in front of the workbench to facilitate the operator's operation;

[0004] The traction type mobile workbench is to install the reducer on the ground in front of the workbench. The reducer is fixed and the workbench is driven to move by sprockets, chains and traction hooks. The traction hook is installed on the front side of the mobile platform. There will be interference between the installation of the traction hook and the heat insulation device, and the sprocket box installation position must be grooved at the corresponding position on the ground, which affects the appearance of the ground and the convenience of people walking;

[0005] The overall footprint of the hydraulic cylinder driven mobile platform is relatively large. The hydraulic cylinder is installed on the ground at the front or rear side of the mobile platform, which is inconvenient for personnel to operate and walk. In addition, in a high temperature working environment, it is easy to cause fire due to aging and oil leakage of pipe joints and seals.

[0006] In summary, the currently known technologies mentioned above all have their more significant disadvantages, and it is urgent to invent a special mobile workbench structure to meet the requirements of the development trend of modern isothermal forging hydraulic presses.

[0047] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0048] like Figures 1 to 10 As shown, a mobile workbench dedicated to an isothermal forging hydraulic press includes a base 1 and hydraulic equipment columns 22 arranged at the four corners of the upper surface of the base 1:

[0049] Two side plates 2 are symmetrically arranged on the front and rear sides of the base 1, and a bidirectional output reducer 3 is fixedly connected to the surface of the front side plate 2, and both ends of the bidirectional output reducer 3 are drivingly connected to a power transmission component 4, and a rack 15 is meshed at the top of the power transmission component 4;

[0050] A workbench 16 is provided on the upper surface of the base 1 for horizontal movement, and two racks 15 are symmetrically fixedly connected to both sides of the workbench 16;

[0051] The surface of the power transmission component 4 is meshed with a locking component 5, the surface of the locking component 5 is penetrated by a rotating locking responder 7 for controlling the locking component, and the surface of the locking responder 7 is penetrated by a sliding locking component 6 for further controlling the locking component 5;

[0052] The inner wall of the base 1 is fixedly connected with a calibration guide rail 12 and a load-bearing guide rail 13. Two calibration guide wheels 10 and load-bearing guide wheels 11 are symmetrically fixed at the four corners of the lower surface of the workbench 16. The calibration guide wheel 10 is arranged to roll with the surface of the calibration guide rail 12, and the load-bearing guide wheel 11 is arranged to roll on the surface of the load-bearing guide rail 13.

[0053] The lower surface of the bidirectional output reducer 3 is fixedly connected with a servo motor 8 for driving the same;

[0054] Four clamping plates 21 are fixedly connected to the lower surface of the workbench 16, and the clamping plates 21 are symmetrically arranged on both sides of the calibration guide wheel 10 and the load-bearing guide wheel 11 in pairs;

[0055] Hydraulic clamping device 20;

[0056] The hydraulic clamping device 20 includes a hydraulic cylinder 201 fixedly connected to the inner wall of the base 1, a telescopic end 202 is arranged above the hydraulic rod, and a clamping claw 203 is fixedly connected to the top of the telescopic end 202, and a guide pad 204 is slidably arranged on the surface of the clamping claw 203, and the guide pad 204 is fixedly connected to the upper surface of the base 1, and the clamping claw 203 and the guide pad 204 are arranged flush with the upper surfaces of the calibration guide rail 12 and the load-bearing guide rail 13.

[0057] This solution provides a precisely controlled power source through a servo motor 8 (with a built-in rotary encoder), and in combination with a bidirectional output reducer 3, effectively improves the control accuracy and traction torque, thereby realizing precise control of the mobile workbench 16 of the isothermal forging hydraulic press. The two power components respectively engage the two racks 15 to realize the movement of the workbench 16, while minimizing the height of the workbench 16, meeting the best ergonomic operation requirements, eliminating the reliance on traditional traction hooks and hydraulic cylinder drives, and conforming to the development trend of modern isothermal forging hydraulic presses. The bidirectional output reducer 3 is driven by a servo motor 8, which can accurately control the moving speed and positioning accuracy.

[0058] After the workbench 16 moves to the designated position, the metal block 73 is adsorbed by starting the electromagnet 72, and the hexagonal shaft 52 is stuck in the polygonal groove 46, so that the input gear 42 and the synchronous gear 51 are coaxially driven through the hexagonal shaft 52, and the gear system is in a locked state, thereby achieving temporary stable and safe positioning, preventing position deviation, and ensuring safety and accuracy. The telescopic cylinder 62 is provided with high-pressure air by the air pump, so that it is in a continuous extension state, and the grinding block 69 fits the lower surface of the transfer gear 43. When displacement occurs, the rack 15 moves in the opposite direction to drive the output gear 45 to rotate, so that the transfer gear 43 drives the deflection frame 71 to deflect through the grinding block 69, and realizes anti-displacement safety protection in two directions. After each stop, the system automatically replenishes gas for the telescopic cylinder 62, even if the staff does not energize the electromagnet 72, it can ensure safety, and at the same time facilitate the staff to make small displacement adjustments, and lock the hexagonal shaft 52 after adjustment, further improving the safety of use and preventing the workbench 16 from sliding in any direction. In addition, when the synchronous gear 51 is not in meshing state, the deflection frame 71 can still meet the demand for small displacement adjustment and has a flexible use effect.

[0059] Specifically, Figure 2 As shown: the arc-shaped side wall of the calibration guide wheel 10 is convex, and the surface of the calibration guide rail 12 matched with the calibration guide wheel 10 is concave, and the contact surfaces of the load-bearing guide wheel 11 and the load-bearing guide rail 13 are both planes.

[0060] The side wall of the calibration guide wheel 10 is arranged in a convex shape so that it can fit in the shape of the surface of the calibration guide rail 12 so that it will not deviate, thereby ensuring a stable moving state. At the same time, the load-bearing guide rail 13 has a larger fitting surface with the load-bearing guide wheel 11, and has a better supporting effect.

[0061] Specifically, Figure 4As shown: the power transmission assembly 4 includes an input shaft 41 that is in transmission cooperation with one end of the bidirectional output reducer 3, one end of the input shaft 41 is fixedly connected to an input gear 42, the surface of the input gear 42 is meshed with a transfer gear 43, the upper surface of the transfer gear 43 is fixedly connected to an output shaft 44, the top end of the output shaft 44 is fixedly connected to an output gear 45, and the output gear 45 is meshed with the rack 15 for transmission;

[0062] A polygonal groove 46 that cooperates with the locking assembly 5 is formed on one side of the input gear 42 .

[0063] The input shaft 41 meshes with the transfer gear 43 through the input gear 42 , and rotates with the output gear 45 through the output shaft 44 , so that the output gear 45 can move with the rack 15 .

[0064] Specifically, Figure 1 As shown, the lower surfaces of the calibration guide rail 12 and the load-bearing guide rail 13 are fixed with pillars 18 for supporting them, and the surface of the side plate 2 is provided with through holes 17 for matching the installation of the calibration guide rail 12 and the load-bearing guide rail 13.

[0065] By setting the pillar 18, the load-bearing guide rail 13 and the calibration guide rail 12 can be supported in coordination. At the same time, the perforations 17 on the surface of the side panel 2 can be used to fix the calibration guide rail 12 and the load-bearing guide rail 13, and can also be used to slide through the calibration guide wheel 10 and the load-bearing guide wheel 11.

[0066] Specifically, Figure 5 As shown: the locking assembly 5 includes a synchronous gear 51 meshing with the intermediate gear 43, a hexagonal hole 53 is penetrated on one side of the synchronous gear 51, a hexagonal shaft 52 slides through the inner wall of the hexagonal hole 53, the hexagonal shaft 52 is matched with the inner wall diameter of the polygonal groove 46, and one end of the hexagonal shaft 52 is fixedly connected to a tail block 54.

[0067] By matching the hexagonal shaft 52 with the polygonal groove 46 , the synchronous gear 51 and the input gear 42 are in a coaxial rotation state, and the same-direction rotation is engaged with the transfer gear 43 , so that it cannot rotate, and the whole is locked.

[0068] Specifically, Figure 2 As shown: the surface of the side plate 2 is provided with a notch 19 for cooperating with the locking responder 7 to rotate, and a protective shell 14 is fixedly connected to one side of the notch 19 .

[0069] By providing the notch 19 , when the deflection frame 71 rotates by ninety degrees, the groove can cooperate to avoid movement interference, and the protective shell 14 fixed on the surface can protect the power transmission component 4 , the locking component 5 and the locking component 6 .

[0070] Specifically, Figure 5 As shown: the locking responder 7 includes a deflection frame 71 that penetrates and rotates on the surface of the hexagonal shaft 52, and also includes a rotating seat 74 that is rotatably connected to the surface of the tail block 54, and a plurality of horizontal guide rods 75 are fixedly connected to one side of the rotating seat 74. The surface of the deflection frame 71 is provided with limiting holes 76 for cooperating with the sliding of the horizontal guide rods 75. The surface of the deflection frame 71 is fixedly connected with an electromagnet 72, and the surface of the rotating seat 74 is fixedly connected with a metal block 73 that cooperates with the electromagnet 72.

[0071] By adopting the rotating seat 74, the tail block 54 can rotate on the inner wall of the rotating seat 74. The rotating seat 74 is acted upon by the electromagnet 72 through the metal block 73, so that it can move lightly during the adsorption process, so that the hexagonal shaft 52 can move axially. The hexagonal shaft 52 rotates and slides axially on the inner wall of the deflection frame 71, and can rotate on the inner wall of the deflection frame 71. At the same time, as the rotating seat 74 pushes it, the hexagonal shaft 52 can be inserted into the polygonal groove 46 as it moves.

[0072] Specifically, Figure 2 As shown: the surfaces of the input shaft 41 and the output shaft 44 are fixed to the surface of the side plate 2 through bearing seats, the input shaft 41 and one side of the bidirectional output reducer 3 are matched through a coupling transmission, and the lower surface of the transfer gear 43 is provided with a concave-convex texture of a matching module.

[0073] The bearing seat stably fixes the input shaft 41 and the output shaft 44, wherein the concavo-convex texture on the lower surface of the rotating gear 43 can cooperate with the grinding block 69, so that the grinding block 69 has sufficient fitting force.

[0074] Specifically, Figure 4 As shown: the locking assembly 6 comprises a mounting frame 61 fixedly connected to the surface of the side plate 2, a telescopic cylinder 62 is fixedly connected to the surface of the mounting frame 61, a lower pressing plate 63 is fixedly connected to the top of the telescopic cylinder 62, an elastic torsion member 64 is installed on the upper surface of the lower pressing plate 63, an upper pressing plate 65 is installed on the upper surface of the elastic torsion member 64, and a spline shaft 67 is fixedly connected to the upper surface of the upper pressing plate 65;

[0075] The top of the spline shaft 67 is fixedly connected with a sliding sleeve 68, and the upper surface of the sliding sleeve 68 is fixedly connected with a grinding block 69. The four corners of the upper pressure plate 65 are fixed with vertical guide rods 60, and the vertical guide rods 60 penetrate and slide on the surface of the deflection frame 71.

[0076] The locking assembly 6 further includes a spline sleeve 66 penetrating and fixed on the surface of the deflection frame 71 , and the spline sleeve 66 is spline-fitted on the surface of the spline shaft 67 .

[0077] The mounting frame 61 can provide fixed support for the telescopic cylinder 62. At the same time, an elastic torsion member 64 is provided between the lower pressure plate 63 and the upper pressure plate 65. The elastic torsion member 64 is a rotating pin shaft surface provided with a torsion spring, which can ensure that the lower pressure plate 63 does not move when the upper pressure plate 65 rotates and the torsion spring twists, thereby providing a reset force for the upper pressure plate 65.

[0078] The vertical guide rod 60 can slide on the surface of the deflection frame 71, so that when the lower pressure plate 63 and the upper pressure plate 65 are moved upward synchronously under the action of the telescopic cylinder 62, the vertical guide rod 60 can play a stabilizing and orienting role. At the same time, when the upper pressure plate 65 is twisted, it can deflect synchronously with the deflection frame 71.

[0079] Specifically, Figure 6 As shown, the hexagonal shaft 52 axially penetrates and slides on the inner wall of the sliding sleeve 68, and the sliding sleeve 68 is in a long strip shape.

[0080] By providing a long strip-shaped sliding sleeve 68, the hexagonal shaft 52 can slide in the sliding sleeve 68 during axial movement, and at the same time, the axial movement of the spline shaft 67 brings about a height change of the grinding block 69, thereby realizing a staggered matching movement without interference.

[0081] This solution provides a precisely controlled power source through the servo motor 8. The servo motor 8 further improves the control accuracy and sufficient traction torque through the cooperation of the bidirectional output reducer 3, so that it drives two power components and engages two racks 15 respectively, so that when the racks 15 move, the workbench 16 moves accordingly;

[0082] When the workbench 16 moves to the specified position, the electromagnet 72 is started to adsorb the metal block 73, and the hexagonal shaft 52 is inserted into the polygonal groove 46. At this time, the input gear 42 and the synchronous gear 51 are in a coaxial transmission state based on the hexagonal shaft 52, and the input gear 42 and the synchronous gear 51 are meshed together on the surface of the transfer gear 43, so that the whole is in a locked state, and can achieve temporary stable and safe positioning at the specified position without displacement, thereby ensuring safety and position accuracy.

[0083] The air pump is started to provide high-pressure air to the telescopic cylinder 62, and the air outlet valve of the telescopic cylinder 62 is closed. At this time, the telescopic cylinder 62 is in a continuous extension state. At this time, the grinding block 69 is in contact with the lower surface of the transfer gear 43. If displacement occurs, the rack 15 moves in the opposite direction to rotate the output gear 45. The transfer gear 43 and the output gear 45 rotate coaxially through the output shaft 44, so that the transfer gear 43 deflects the spline shaft 67 through the grinding block 69, and the spline shaft 67 deflects the deflection frame 71 through the spline sleeve 66 sliding on the surface, so that the synchronous gear 51 moves in an arc track and directly aligns with the input The gear 42 and the transfer gear 43 are meshed synchronously, and the deflection direction of the deflection frame 71 is different when the displacement directions are different, so that anti-displacement safety protection in two directions can be achieved. This solution automatically replenishes gas to the telescopic cylinder 62 each time the workbench 16 stops, which ensures safety when the electromagnet 72 is not energized, and can facilitate small displacement adjustments by the staff. After the adjustment, the hexagonal shaft 52 is locked to prevent it from sliding in any direction, and when the deflection angle of the synchronous gear 51 does not reach the meshing state, it can meet the flexible use requirements of small displacement adjustments under use.

[0084] The gas in the telescopic cylinder 62 is released, and then the spline shaft 67 slides downward in the spline sleeve 66 along with the telescopic cylinder 62 under the action of gravity. The grinding block 69 loses the friction limit of the transfer gear 43, so that the spline shaft 67 is fixed in the upper pressure plate 65 and is subjected to the elastic force of the elastic torsion member 64, so that it is quickly reset.

[0085] When the workbench 16 moves to the specified position, the mold above it needs to be hydraulically clamped by the mold installed above the hydraulic equipment column 22. Therefore, when the two calibration guide wheels 10 and the two load-bearing guide wheels 11 move to the working position, they just move to the top of the hydraulic clamping device 20. At this time, the clamping claw 203 of the hydraulic clamping device 20 is in a horizontal state with the guide pad 204 and the calibration guide rail 12. Driven by the hydraulic cylinder 201, the height of the guide pad 204 remains unchanged, and the clamping claw 203 descends with the telescopic end 202 until the clamping plate 21 contacts the guide pad 204 and is pressed by the clamping claw 203. At this time, the two load-bearing guide wheels 11 and the calibration guide wheel 10 are in a suspended state, and the overall positioning support is realized. The overall support method can adapt to a larger clamping pressure. At the same time, the locking method is relatively stable, which can meet the influence of different mold eccentric forces. In addition, the guide wheels are not subjected to force during the clamping process to avoid damage, thereby improving the stability of the overall operation.

[0086] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
