Description

Technical Field

[0001] The invention relates to the technical field of hydraulic presses, in particular to a high-efficiency hydraulic press. Background Art

[0002] A high-efficiency hydraulic press is a machine that uses liquid static pressure to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing and forming processes. Existing high-efficiency hydraulic presses are divided into four-column, horizontal, vertical frame and multi-layer steel belt winding frame according to their structural forms.

[0003] Existing high-efficiency hydraulic presses usually move the upper pressure plate through a hydraulic cylinder. However, hydraulic oil leakage may occur in the hydraulic cylinder after long-term use, especially when the sealing ring of the hydraulic cylinder is damaged or the oil pipe or joint leaks. The hydraulic oil may leak from the high-pressure side to the low-pressure side, thereby reducing the effective working area of ​​the hydraulic cylinder and making it unable to provide sufficient pressure to support the upper pressure plate. When the pressure of the hydraulic cylinder drops to a certain level, the upper pressure plate will suddenly fall due to gravity, causing a safety hazard.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing high-efficiency hydraulic presses on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

[0041] A groove 2110 is provided on the top of the upper pressing plate 13. There are four grooves 2110. The inner cavity of the groove 2110 is rotatably connected to two transmission shafts 2111.

When the rotating rod 2105 rotates rapidly, it will drive the concave block 2106 to move in a circular shape. Through the effect of inertia, the block 2107 will rotate at a certain angle, so that the first elastic sheet 2108 is deformed by force, so that the block 2107 is stuck in the slot. 2109, thereby locking the upper pressure plate 13, and when the rotating rod 2105 is rotated, the ratchet 2115 will be driven to rotate.

[0045] See also Figure 1-14 The present invention provides a technical solution: a high-efficiency hydraulic press. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The safety mechanism 2 also includes a support unit 22, which is arranged on one side of the upper pressure plate 13, and the support unit 22 is used to support the upper pressure plate 13.

[0046] As a further limitation of the safety mechanism 2 of the present invention, the support unit 22 includes a mounting shell 2201 fixedly connected to one side of the upper pressure plate 13, the inner cavity of the mounting shell 2201 is provided with a first airbag 2202, one side of the first airbag 2202 is fixedly connected to a support block 2203, the surface of the support block 2203 is slidably connected to the inner cavity of the mounting shell 2201, the other side of the first airbag 2202 is fixedly connected to the inner wall of the mounting shell 2201, the inner wall of the mounting shell 2201 is fixedly connected to a first telescopic rod 2204, and the telescopic end of the first telescopic rod 2204 is fixedly connected to the connecting plate 22 05, a first spring 2206 is movably sleeved on the surface of the first telescopic rod 2204, one end of the first spring 2206 is fixedly connected to the connecting plate 2205, the other end of the first spring 2206 is fixedly connected to the inner cavity of the mounting shell 2201, one side of the connecting plate 2205 is fixedly connected to the second airbag 2207, one side of the second airbag 2207 is fixedly connected to the inner cavity of the mounting shell 2201, one side of the second airbag 2207 is fixedly connected to a connecting pipe 2208, one end of the connecting pipe 2208 is fixedly connected to the first airbag 2202, and a movable sleeve is provided on the top of the connecting plate 2205.

The top of the mounting shell 2201 is provided with a limit hole 2211 used in conjunction with the limit block 2210. By setting the support unit 22, when the hydraulic cylinder 15 leaks, the limit block 2210 will be separated from the limit hole 2211. Since the first spring 2206 is in a compressed state at this time, the first spring 2206 squeezes the second airbag 2207, so that the first airbag 2202 expands, thereby pushing the support block 2203 out of the inner cavity of the mounting shell 2201. When the pressure plate 13 moves downward, the upper pressure plate 13 is supported by the support block 2203, so that there is a gap between the upper pressure plate 13 and the lower pressure plate 11, so as to avoid crushing the operator and increase safety. Among them, when the limit block 2210 is located in the limit hole 2211, the second airbag 2207 is in a stretched state and filled with gas, while the first airbag 2202 is in a compressed state, and a friction pad is fixed on the surface of the support block 2203, and the friction pad is in close contact with the inner wall of the mounting shell 2201, so as to avoid vibration of the mounting shell 2201 and cause the support block 2203 to detach from the inner cavity of the mounting shell 2201.

[0047] The inner cavity of the mounting shell 2201 is fixedly connected with a guide rod 2212, and the surface of the guide rod 2212 is slidably connected with the inner cavity of the support block 2203. There are two guide rods 2212, and the support block 2203 is made of steel.

By setting the rubber tube 2213, the oil storage box 2214 and the sealing plug 2215 for coordinated use, One end of the rubber tube 2213 is fixedly connected to the outer shell of the hydraulic cylinder 15, so that the hydraulic oil in the hydraulic cylinder 15 enters the rubber tube 2213, and the sealing plug 2215 is moved by the pressure of the hydraulic oil, so that the positioning pin 2216 is stuck in the positioning hole 2219, and at this time the tension spring 2218 will be deformed by force. When the hydraulic cylinder 15 leaks, the hydraulic oil in the rubber tube 2213 will cancel the pressure on the sealing plug 2215, so that the tension spring 2218 drives the sealing plug 2215 to move, thereby causing the positioning pin 2216 to disengage from the positioning hole 2219, thereby causing the limit block 2210 to disengage from the inner cavity of the limit hole 2211, wherein a return spring is arranged inside the connecting plate 2205 to drive the limit block 2210 to move downward.

[0049] The specific implementation of this embodiment is as follows: when the hydraulic cylinder 15 leaks, the hydraulic oil in the rubber tube 2213 will cancel the pressure on the sealing plug 2215, so that the tension spring 2218 drives the sealing plug 2215 to move, so that the positioning pin 2216 disengages from the positioning hole 2219, thereby causing the limit block 2210 to disengage from the inner cavity of the limit hole 2211, and the limit block 2210 will disengage from the limit hole 2211. Since the first spring 2206 is in a compressed state at this time, the first spring 2206 squeezes the second airbag 2207, thereby causing the first airbag 2202 to expand, thereby pushing the support block 2203 out of the inner cavity of the mounting shell 2201. When the upper pressure plate 13 moves downward, the upper pressure plate 13 is supported by the support block 2203, so that there is a gap between the upper pressure plate 13 and the lower pressure plate 11, thereby avoiding crushing injuries to the operator and increasing safety.

One end of the belt 32 moves downward, and the other end of the toothed belt 32 moves upward, thereby driving the first gear 33 to rotate, so that the second gear 35 rotates in the inner cavity of the tooth groove 36, thereby achieving the effect of driving the movable plate 16 to move, so that the movable plate 16 moves to the bottom of the upper pressure plate 13, and when the lower pressure plate 11 moves upward, one end of the toothed belt 32 moves upward, and the other end of the toothed belt 32 moves downward, thereby achieving the effect of driving the movable plate 16 to move in the opposite direction. When the movable plate 16 moves to the outermost end, the smooth part of the toothed belt 32 will contact the first gear 33 to avoid jamming.

An air cavity 38 is opened on the top of the adjusting rod 31, and a piston 39 is slidably connected to the inner cavity of the air cavity 38. A U-shaped rod 310 is fixedly connected to the top of the piston 39. One end of the U-shaped rod 310 is fixedly connected to the top of the sliding block 37. One side of one of the adjusting rods 31 is fixedly connected to an air pipe 314, and one end of the air pipe 314 is fixedly connected to one side of the other adjusting rod 31. By setting the sliding block 37, the air cavity 38, the piston 39 and the U-shaped rod 310 for coordinated use, when one of the sliding blocks 37 moves, it will drive the U-shaped rod 310 to move downward, so that the piston 39 moves in the cavity, so that pressure is generated in the cavity, so that the gas is squeezed into the other cavity, so that the other piston 39 is squeezed and moved upward, thereby achieving the effect of one sliding block 37 moving upward and the other sliding block 37 moving downward.

[0055] The specific implementation of this embodiment is as follows: when the upper pressure plate 13 moves downward, it will drive one of the sliders 37 to move downward, thereby driving the U-shaped rod 310 to move downward, causing the piston 39 to move in the cavity, generating pressure in the cavity, causing the gas to be squeezed into another cavity, causing the other piston 39 to be squeezed and moved upward, thereby driving the first gear 33 to rotate, causing the second gear 35 to rotate in the inner cavity of the tooth groove 36, thereby achieving the effect of driving the movable plate 16 to move, so that the movable plate 16 moves to the bottom of the upper pressure plate 13, and when the lower pressure plate 11 moves upward, it will drive one of the sliders 37 to move upward, causing one end of the toothed belt 32 to move upward, and the other end of the toothed belt 32 to move downward, causing the second gear 35 to rotate in the opposite direction, thereby achieving the effect of driving the movable plate 16 to move in the opposite direction, and when the movable plate 16 moves to the outermost end, the smooth part of the toothed belt 32 will contact the first gear 33 to avoid jamming.
