Description

Technical Field

[0001] This invention relates to the field of presses, and more particularly to a press with an anti-eccentricity component. Background Technology

[0002] A press (including punch presses and hydraulic presses) is a sophisticated and versatile press. It is characterized by its wide range of applications and high production efficiency, and can be widely used in processes such as cutting, punching, blanking, bending, riveting, and forming.

[0003] Off-center loading refers to the situation where the same load is placed at different positions on the weighing instrument's load-bearing structure, and the indicated value does not exceed the maximum permissible error specified for that load.

[0004] Existing hydraulic presses include a machine body and a slider that can move up and down along a guide rail. Two hydraulic cylinders are symmetrically arranged on both sides of the slider's center line above the slider. The cylinder bodies of the two hydraulic cylinders are fixed to the machine body. The lower part of the piston rods of the two hydraulic cylinders is provided with connecting seats. Screw holes are evenly distributed on the outer periphery of the connecting seats. Screws pass through the screw holes to connect the connecting seats to the top of the slider. When the slider moves to the bottom dead center and is pressurized, the force is entirely borne by the screws. Since the screws and slider are rigidly connected, when there is an off-center load, it will cause certain hidden damage to the screws. If the off-center load of the machine tool is serious and the off-center load force is too large, it will cause irreversible damage to the connecting screws. In severe cases, the screws will break, causing the slider to detach from the hydraulic cylinders. Summary of the Invention

[0005] The purpose of this invention is to provide a press with an anti-eccentric loading component to solve the above-mentioned technical problems.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A press with an anti-eccentric load component includes a first overload protection cylinder and a second overload protection cylinder arranged on the left and right sides of the slide block. The first overload protection cylinder is equipped with a first mold height adjustment device, and the second overload protection cylinder is equipped with a second mold height adjustment device. The first overload protection cylinder is connected to a first unloading valve through a connecting pipe, and the second overload protection cylinder is connected to a second unloading valve through a connecting pipe. The first mold height adjustment device and the second mold height adjustment device are worm gear transmission type. The worm of the first mold height adjustment device is connected to a first geared motor, and the worm of the second mold height adjustment device is connected to a second geared motor.

[0008] Preferably, the bottom of the first mold height adjustment device is fixedly connected to an oil spraying mechanism, and the oil spraying mechanism is fixedly connected to fixing parts on both the left and right sides;

[0009] The oil spraying mechanism is used to lubricate the worm gear transmissions on the first mold height adjustment device and the second mold height adjustment device.

[0010] Preferably, the first geared motor and the second geared motor are connected to the heat dissipation mechanism via a connecting mechanism. The heat dissipation mechanism includes a mounting ring, a plurality of connecting seats are fixedly connected to the top of the mounting ring, a plurality of connecting blocks are inserted into the connecting seats, a rotating ring is fixedly connected between the plurality of connecting blocks, and a heat dissipation component is rotatably connected inside the rotating ring.

[0011] Preferably, the heat dissipation assembly includes a connecting frame, which is rotatably connected to a rotating ring. Two fixed rings are provided below the connecting frame, and the two fixed rings are connected by multiple baffles. The fixed rings are fixedly connected to the connecting frame. A reversing component is connected to the bottom of the connecting frame, and a fan blade is connected to the bottom of the reversing component. The bottom of the fan blade is connected to the power shaft of the first reduction motor through the connecting component.

[0012] The beneficial effects of this invention are:

[0013] 1. Based on the rigidity of the machine body and the action of the guiding mechanism, the present invention has already eliminated a certain degree of mold tilting deviation. According to the actual deviation of the mold, the slider is adjusted by controlling the first reduction motor and the second reduction motor, so that the slider is pre-tilted in the opposite direction by a certain deviation, thereby completely eliminating the deviation caused by eccentric load, improving the quality of parts, and extending the service life of the mold.

[0014] 2. By extending the power shafts of the first and second geared motors, the first and second geared motors will drive the fan blades to rotate forward while the mounting ring and baffle rotate in reverse. This allows the mounting ring and baffle to provide auxiliary airflow in the lateral direction. With the help of the mounting ring and baffle, the airflow of the fan blades is multi-directional or expanding, providing better heat dissipation or cooling effect, thereby improving heat dissipation efficiency and the practical function of the fan.

[0015] 3. Since the press is prone to uneven load after working for a period of time, the first and second geared motors will also cause the piston plate to squeeze the lubricating oil when adjusting the uneven load. The sprayed lubricating oil can lubricate the worm gear on the body of the first mold height adjustment device, which is convenient to use. Attached Figure Description

[0026] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0027] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0028] Example 1:

[0029] like Figure 1 As shown, a press with an anti-eccentric load component includes a first overload protection cylinder 1 and a second overload protection cylinder 5 arranged on the left and right sides of the slider. The press is characterized in that: a first mold height adjustment device 2 is installed on the first overload protection cylinder 1, and a second mold height adjustment device 6 is installed on the second overload protection cylinder 5; the first overload protection cylinder 1 is connected to a first unloading valve 4 via a connecting pipe, and the second overload protection cylinder 5 is connected to a second unloading valve 8 via a connecting pipe; the first mold height adjustment device 2 and the second mold height adjustment device 6 are worm gear transmission type; the worm of the first mold height adjustment device 2 is connected to a first reduction motor 3, and the worm of the second mold height adjustment device 6 is connected to a second reduction motor 7.

[0030] The worm gear is rotated by the first reduction motor 3 and the second reduction motor 7, which in turn drives the worm wheel to rotate. This allows control of the first mold height adjustment device 2 and the second mold height adjustment device 6, so that the slider is pre-tilted in the opposite direction by a certain deviation, thereby completely eliminating the deviation caused by eccentric load, improving the quality of parts, and extending the service life of the mold.

[0031] Example 2:

[0032] like Figure 2-9 As shown, while other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that: the bottom of the first mold height adjustment device 2 is fixedly connected to an oil spraying mechanism, and the left and right sides of the oil spraying mechanism are fixedly connected to fixing parts 39.

[0033] The oil spraying mechanism is used to lubricate the worm gear transmissions on the first mold height adjustment device 2 and the second mold height adjustment device 6;

[0034] The first geared motor 3 and the second geared motor 7 are connected to the heat dissipation mechanism through a connecting mechanism. The heat dissipation mechanism includes a mounting ring 11. Multiple connecting seats 13 are fixedly connected to the top of the mounting ring 11. Multiple connecting blocks 23 are inserted into the connecting seats 13. A rotating ring 22 is fixedly connected between the multiple connecting blocks 23. A heat dissipation component is rotatably connected inside the rotating ring 22.

[0035] The heat dissipation assembly includes a connecting frame 24, which is rotatably connected to a rotating ring 22. Two fixed rings 21 are provided below the connecting frame 24. The two fixed rings 21 are connected to each other through multiple baffles 20. The fixed rings 21 are fixedly connected to the connecting frame 24. A reversing component is connected to the bottom of the connecting frame 24. A fan blade 16 is connected to the bottom of the reversing component. The bottom of the fan blade 16 is connected to the power shaft of the first reduction motor 3 through a connecting component.

[0036] The reverse assembly includes a mounting frame 19, inside which are four bevel gears 43 meshing. A third drive shaft 44 is fixedly connected to each bevel gear 43. The third drive shaft 44 passes through the mounting frame 19 and is rotatably connected to the mounting frame 19. The third drive shaft 44 is fixedly connected to a connecting frame 24. A mounting frame 17 is fixedly connected to the mounting frame 19 and is fixedly connected to the first reduction motor 3.

[0037] The connecting assembly includes a transmission box 14, a second transmission shaft 27 is fixedly connected to the bottom of the transmission box 14, the second transmission shaft 27 is connected to the power shaft of the first reduction motor 3, a transmission block 15 is inserted into the transmission box 14, a first transmission shaft 18 is fixedly connected to the top of the transmission block 15, and the first transmission shaft 18 is fixedly connected to the fan blade 16.

[0038] The connecting block 23 is connected to the connecting seat 13 via the pin 12;

[0039] The connecting mechanism includes a connecting sleeve 10, with multiple connecting boxes 9 fixedly connected inside the connecting sleeve 10. A second locking strip 29 is slidably connected inside the connecting box 9. The second locking strip 29 is connected to the connecting box 9 by multiple springs 26. A pull rod 25 is provided through the connecting box 9. The pull rod 25 is fixedly connected to the second locking strip 29 and slidably connected to the connecting box 9. A first locking strip 28 is locked onto the second locking strip 29. The first locking strip 28 is fixedly connected to the first reduction motor 3.

[0040] Align the connecting box 9 inside the connecting sleeve 10 with the first locking strip 28 and insert it directly, so that the first locking strip 28 presses against the second locking strip 29, and the second locking strip 29 will engage with the first locking strip 28 under the action of the spring 26, thus achieving the limiting function;

[0041] When disassembly is required, the lever 25 can be pulled to move the second locking strip 29 away from the first locking strip 28. The second locking strip 28 and the second locking strip 29 are not interlocked, allowing for easy disassembly.

[0042] When the first geared motor 3 and the second geared motor 7 are needed, the transmission shaft at the tail of the first geared motor 3 and the second geared motor 7 will drive the second transmission shaft 27 to rotate. The second transmission shaft 27 will drive the transmission box 14 to rotate. The transmission box 14 will drive the first transmission shaft 18 to rotate through the transmission block 15. The first transmission shaft 18 will drive the fan blade 16 to rotate. The fan blade 16 will drive the heat inside the first geared motor 3 and the second geared motor 7 to be discharged, which will achieve the effect of heat dissipation and cooling.

[0043] Furthermore, the rotation of the fan blade 16 will also drive the third drive shaft 44 to rotate, which in turn will drive the bevel gear 43. Multiple bevel gears 43 mesh, eventually causing the third drive shaft 44 at the top of the mounting frame 19 to rotate in the opposite direction. The reverse rotation of the third drive shaft 44 will drive the connecting frame 24 to rotate, which in turn drives the rotating ring 22 and the baffle 20 to rotate. Since the rotation of the rotating ring 22 and the baffle 20 is opposite to that of the fan blade 16, the heat generated by the fan blade 16 can be dissipated from different directions, thus achieving a better heat dissipation effect.

[0044] Since the rotating ring 22 is connected to the connecting seat 13 via the connecting block 23, and the connecting block 23 and the connecting seat 13 are connected by the pin 12, it is also convenient to disassemble when necessary.

[0045] Example 3:

[0046] like Figure 2-9 As shown, while all other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that: the fuel injection mechanism includes an oil reservoir 31, a fixing member 39 is fixedly connected to the oil reservoir 31, a reciprocating screw 36 is rotatably connected inside the oil reservoir 31, a gear 35 is fixedly connected to the reciprocating screw 36, a piston plate 37 is threadedly connected to the reciprocating screw 36, the piston plate 37 is slidably connected to the oil reservoir 31, and a first rotating rod 38 is provided below the reciprocating screw 36, the first rotating rod 38 passes through the oil reservoir 31 and rotates with the oil reservoir 31. A rotating disk 32 is fixedly connected to the first rotating rod 38. Multiple locking teeth 34 are inserted into the rotating disk 32. The locking teeth 34 are connected to the rotating disk 32 by bolts 33. The locking teeth 34 on the rotating disk 32 are meshed with gears 35. The worm gear on the first mold height adjustment device 2 is fixedly connected to the second rotating rod 42. Both the second rotating rod 42 and the first rotating rod 38 are fixedly connected to pulleys 41. Two adjacent pulleys 41 are connected by a connecting belt 40. An oil injection pipe 30 is installed on the oil tank 31. The oil injection pipe 30 is aligned with the worm gear.

[0047] When the first geared motor 3 and the second geared motor 7 drive the worm to rotate, the worm will drive the second rotating rod 42 to rotate. The second rotating rod 42 will drive the first rotating rod 38 to rotate through the pulley 41 and the connecting belt 40. The first rotating rod 38 will drive the rotating disk 32 to rotate. Since the rotating disk 32 is equipped with a retaining tooth 34, the retaining tooth 34 can make the gear 35 rotate. The gear 35 drives the reciprocating screw 36 to rotate. The reciprocating screw 36 makes the piston plate 37 move. The movement of the piston plate 37 can squeeze the lubricating oil inside the oil storage tank 31, so that the lubricating oil is sprayed from the oil injection pipe 30 to the worm gear, thereby lubricating the worm gear.

[0048] Since the retaining teeth 34 on the rotating disk 32 are detachable, the more retaining teeth 34 there are, the greater the rotation angle of the gear 35 and the greater the rotation angle of the reciprocating screw 36, thus the greater the moving distance of the piston plate 37. Therefore, by controlling the number of retaining teeth 34, the amount of lubricating oil injected each time can be controlled.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
