Description

Technical Field

[0001] The invention relates to the technical field of hydraulic equipment, in particular to a highly efficient and fully automatic internal high-pressure hydraulic forming production equipment. Background Art

[0002] In the Chinese patent with the patent publication number CN104338818B, an internal high pressure forming device is disclosed, including a clamping press, an internal high pressure mold, a first lateral hydraulic cylinder and a second lateral hydraulic cylinder, wherein a third lateral hydraulic cylinder is arranged inside the first lateral hydraulic cylinder, and a third pusher is arranged at the output end of the third lateral hydraulic cylinder; a liquid filling through hole is longitudinally arranged at the front end of the third pusher, wherein the liquid outlet of the liquid filling through hole is arranged on the end face of the free end of the third pusher, and the liquid inlet of the liquid filling through hole is arranged on the side wall of the third pusher and can be connected with the first liquid filling hole. The present invention can make the inside of the tube blank obtain a higher internal pressure (greater than 400MPa) during the forming process, so as to form some complex workpieces with large deformation and some hollow components with large volume and thick tube wall, and at the same time, use the higher internal pressure for hydraulic punching, and the higher internal pressure directly pushes out the blank after punching, which reduces the subsequent cleaning work and improves the production efficiency.

[0003] However, the above patent still has the following defects when used specifically:

[0004] 1. The stamping method of the mold mentioned in the above patent is relatively single, and only one mold can be used for stamping at a time. This means that during the production process, it is necessary to wait for the stamping component of the previous mold to be completely stamped and disassembled and cleaned before the next component can be stamped. This single and linear production method will directly lead to the stagnation of the production line once the mold is damaged, which will have a serious impact on the continued production. Specifically, the damage of the mold not only means that the component currently being processed cannot be completed, but it is also likely to cause the entire production line to stagnate, because the subsequent components cannot be stamped without the mold. This stagnation will not only reduce production efficiency, but may also lead to waste of resources and increased costs due to production interruptions.

[0005] 2. Although the above patent can utilize a relatively high internal pressure for hydraulic punching, and although the hydraulic punching technology is adopted, the blanking material after punching is successfully pushed out directly by utilizing a relatively high internal pressure, thereby reducing the subsequent cleaning work and significantly improving the production efficiency, however, during the frequent use of the internal pressure mold, the degree of damage to the mold will be aggravated due to the continuous stamping wear between the molds, and since these molds are firmly fixed on the hydraulic table, once the mold needs to be replaced or repaired, it will become quite cumbersome, which not only increases the difficulty of equipment maintenance, but also makes the disassembly of the stamping components extremely difficult. These problems will undoubtedly have a certain negative impact on production efficiency, and also increase maintenance costs.

[0006] Therefore, an efficient and fully automatic internal high-pressure hydraulic forming production equipment is proposed to solve the above problems. Summary of the invention

The upper surface of the L-shaped slide is slidably connected to the quick switching table, and slideways and arc-shaped extrusion grooves are symmetrically provided on both sides of the upper surface of the quick switching table. The L-shaped slide passes through the slideway away from the end of the transmission belt.

[0013] As an improvement, the quick switching mechanism also includes a slide, the bottom of the slide is slidably connected to the upper surface of the quick switching table, one side of the bottom of the slide is fixedly connected to the L-shaped slide, the upper surface of the slide is slidably connected to a support, the bottom of one end of the support is fixedly connected to an extrusion rod, the upper surface of the other end of the support is fixedly connected to the internal pressure mold, and the end of the extrusion rod away from the support is slidably connected in the arc extrusion groove.

[0014] As an improvement, a cleaning strip is installed at the bottom of one end of the internal pressure mold away from the slide table.

[0015] As an improvement, the automatic positioning anti-deviation mechanism includes a push plate, a side of the push plate away from the internal pressure mold is fixedly connected to a multifunctional double-sided sliding tooth plate, the bottom of the multifunctional double-sided sliding tooth plate is slidably connected to the hydraulic operating table, and a sealing chamber is provided at one end of the multifunctional double-sided sliding tooth plate away from the push plate, and the bottom of the sealing chamber is fixedly connected to the hydraulic operating table.

[0016] As an improvement, a pneumatic plate is slidably connected in the sealing chamber, the non-tooth surface of the outer surface of the multifunctional double-sided sliding gear plate is slidably connected in the sealing chamber, and the pneumatic plate in the sealing chamber is fixedly connected to the end of the multifunctional double-sided sliding gear plate away from the push plate.

[0017] As an improvement, the automatic positioning anti-deviation mechanism also includes an air pressure hose, and an exhaust hole is opened at one end of the sealed chamber away from the multifunctional double-sided sliding gear plate. The air pressure hose is fixedly connected to the exhaust hole of the sealed chamber, the outer surface of one end of the air pressure hose is fixedly connected to the sealed chamber, and the outer surface of the other end of the air pressure hose is fixedly connected to the push plate.

[0018] As an improvement, a return spring is arranged above the multifunctional double-sided sliding gear plate, one end of the return spring is fixedly connected to the push plate, and the other end of the return spring is fixedly connected to the sealing chamber, arc surface positioning clamps are symmetrically arranged on both sides of the multifunctional double-sided sliding gear plate, the arc surface positioning clamps are rotatably connected to the hydraulic operating table at the middle part of one end away from the internal pressure mold, and sliding teeth are arranged on the circumference of the outer surface of the arc surface positioning clamps close to one end of the multifunctional double-sided sliding gear plate, and the tooth surface of the multifunctional double-sided sliding gear plate is meshed on the sliding teeth arranged on the arc surface positioning clamps.

[0019] Compared with the prior art, the present invention provides a highly efficient fully automatic internal high pressure hydraulic forming production equipment, which has the following beneficial effects:

[0020] Through the setting of the support platform and the slide, the sliding of the slide can drive the support platform to drive the internal pressure mold, thereby realizing the rapid switching of the internal pressure mold. This design makes the replacement of the internal pressure mold extremely efficient, and through the unique arc setting of the arc extrusion groove and the mutual extrusion effect with the extrusion rod, it is ensured that the supports on both sides can achieve automatic avoidance when the internal pressure mold is switched, avoiding the collision problem during the switching of the support platforms. Since the present invention installs high-precision sensor devices at both ends of the slide, and these sensor devices can accurately control the rotation of the motor through the controller, the internal pressure mold switching design can be used to prepare or replace one mold while stamping another internal pressure mold, thereby realizing a continuous and uninterrupted production process. In contrast, the traditional fixed mold method requires stopping the machine to replace the internal pressure mold after each stamping, resulting in low production efficiency. Compared with the single mold fixing method adopted in the prior art, the dual-station design of the device design of the present invention reduces the waiting time of the internal pressure mold during the stamping process, avoids the overheating and aggravated wear of the internal pressure mold caused by long-term continuous work, and in addition, the operator can realize the rapid replacement of the mold after the internal pressure mold is switched, without complicated disassembly and cleaning process, which not only reduces the difficulty of operation, but also reduces the equipment damage and downtime caused by improper operation, thereby reducing the risk of damage caused by improper mold replacement. When the internal pressure mold is positioned on the surface of the hydraulic operating table, the automatic fixation of both sides of the internal pressure mold by the arc surface positioning clamp can not only reduce the production interruption and failure caused by uneven force when stamping asymmetric bent parts, but also reduce the downtime and cost loss caused by equipment failure, and also reduce the need for operators to manually adjust and position the mold, thereby simplifying the operation process, which not only improves work efficiency, but also reduces the labor intensity of operators. Through the design of automatic positioning and anti-deviation mechanism, when the internal pressure mold is positioned on the hydraulic operating table, the push plate can be pushed by the internal pressure mold to move. Through the movement of the push plate, the automatic positioning and anti-deviation mechanism begins to position and fix the two sides of the internal pressure mold. At the same time, the residue generated by high-temperature pressing at the bottom of the internal pressure mold can be effectively removed by the internal gas of the sealed chamber under the transportation of the air pressure hose, thereby avoiding the damage that these residues may cause to the internal pressure mold itself during the stamping process of the internal pressure mold. This not only improves the production efficiency, but also ensures the long-term service life of the internal pressure mold and the high-quality output of the product.

[0044] For further examples, please refer to Figures 1 to 7 As shown:

[0045] The automatic positioning anti-deviating mechanism 3 is used for dust removal on the surface of the hydraulic operating table 1 and automatic positioning of the internal pressure mold 13 before the internal pressure mold 13 is pressed;

[0046] The automatic positioning anti-deviating mechanism 3 comprises a push plate 31, a side of the push plate 31 away from the internal pressure mold 13 is fixedly connected with a multifunctional double-sided sliding tooth plate 32, the bottom of the multifunctional double-sided sliding tooth plate 32 is slidably connected to the hydraulic operating table 1, and a sealing chamber 35 is provided at one end of the multifunctional double-sided sliding tooth plate 32 away from the push plate 31, and the bottom of the sealing chamber 35 is fixedly connected to the hydraulic operating table 1;

[0047] The air pressure plate is slidably connected in the sealing chamber 35, and the non-tooth surface of the outer surface of the multifunctional double-sided sliding tooth plate 32 is slidably connected in the sealing chamber 35. The air pressure plate in the sealing chamber 35 is fixedly connected to the end of the multifunctional double-sided sliding tooth plate 32 away from the push plate 31;

[0048] The automatic positioning anti-deviation mechanism 3 also includes an air pressure hose 36. An exhaust hole is opened at one end of the sealed chamber 35 away from the multifunctional double-sided sliding tooth plate 32. The air pressure hose 36 is fixedly connected to the exhaust hole of the sealed chamber 35. The outer surface of one end of the air pressure hose 36 is fixedly connected to the sealed chamber 35, and the outer surface of the other end of the air pressure hose 36 is fixedly connected to the push plate 31.

[0049] A return spring 34 is arranged above the multifunctional double-sided sliding tooth plate 32, one end of the return spring 34 is fixedly connected to the push plate 31, and the other end of the return spring 34 is fixedly connected to the sealing chamber 35. Arc surface positioning clamps 33 are symmetrically arranged on both sides of the multifunctional double-sided sliding tooth plate 32. The middle part of the arc surface positioning clamp 33 away from the inner pressure mold 13 is rotatably connected to the hydraulic operating table 1. The outer surface circumference of the arc surface positioning clamp 33 near the end of the multifunctional double-sided sliding tooth plate 32 is provided with sliding teeth, and the tooth surface of the multifunctional double-sided sliding tooth plate 32 is meshed with the sliding teeth arranged on the arc surface positioning clamp 33;

[0050] Among them: a cleaning strip is installed at the bottom of the inner pressure mold 13 close to one side of the inner pressure mold 13, and the air pressure hose 36 is fixedly connected to the push plate 31 at a certain angle with the cleaning strip, which is used to clean impurities on the cleaning strip.

[0051] Compared with the prior art, the implementation of this embodiment not only improves the continuity of production, but also reduces the downtime and cost losses caused by equipment failure, while also reducing the need for operators to manually adjust and position the mold, thereby simplifying the operating process, which not only improves work efficiency but also reduces the labor intensity of operators.

[0052] Everything in the above example works like this:

[0053] In the initial state: the motor is not started and the return spring 34 is not compressed.

[0054] The following is the working process of the quick switching mechanism 2 for quick switching of the internal pressure mold 13 after forming:

[0055] When using, Figure 1 As shown, when the internal components of the internal pressure mold 13 on the hydraulic operating table 1 complete the stamping operation, the system precisely controls the operating state of the sensor, thereby activating the motor electrically connected to the sensor, so that the motor starts smoothly. At this time, the motor starts to rotate counterclockwise under the control of the controller;

[0056] like Figure 5 As shown, since the transmission wheel 21 is symmetrically rotatably connected to the bottom of the rapid switching platform 12, and the outer surface of the transmission wheel 21 is transmission-connected to the transmission belt 22, since the motor is installed on the side of the rapid switching platform 12 away from the hydraulic operating platform 1, and the motor driving shaft is fixedly connected to the middle of the transmission wheel 21 away from the side of the hydraulic operating platform 1, when the motor rotates counterclockwise, it will drive the transmission wheel 21 to start driving the transmission belt 22 in the same direction in the counterclockwise direction. Since the two sides of the transmission belt 22 are respectively fixed to the L-shaped slide plate 23, and the upper surface of the L-shaped slide plate 23 is slidingly connected to the rapid switching platform 12, since the slideways 24 and the arc-shaped extrusion grooves 25 are symmetrically opened on both sides of the upper surface of the rapid switching platform 12, and the end of the L-shaped slide plate 23 away from the transmission belt 22 passes through the slideway 24, the counterclockwise transmission through the transmission belt 22 will drive the following Figure 5 The right L-shaped slide plate 23 shown in the figure moves upward, that is, moves toward the side close to the hydraulic operating table 1, and the L-shaped slide plate 23 on the left side of the transmission belt 22 moves downward, that is, moves away from the side of the hydraulic operating table 1. Since the bottom of the slide 26 is slidably connected to the upper surface of the fast switching table 12, one side of the bottom of the slide 26 is fixedly connected to the L-shaped slide plate 23, as shown in FIG. Figure 3 As shown in FIG. 1 , when the L-shaped slide plate 23 on the right side of the fast switching platform 12 slides along the fast switching platform 12 toward the side close to the hydraulic operating platform 1, the L-shaped slide plate 23 on the left side of the upper surface of the fast switching platform 12 slides along the fast switching platform 12 toward the end away from the hydraulic operating platform 1, as shown in FIG. Figure 3As shown, when the supports 27 on both sides of the upper surface of the fast switching platform 12 are close to each other, at this time, because the upper surface of the slide 26 is slidably connected to the support 27, the bottom of one end of the support 27 is fixedly connected to the extrusion rod 28, and the upper surface of the other end of the support 27 is fixedly connected to the internal pressure mold 13, and the end of the extrusion rod 28 away from the support 27 is slidably connected to the arc extrusion groove 25. The mutual extrusion between the arc extrusion groove 25 and the extrusion rod 28 will drive the support 27 on the right side to slide to the right along the slide 26, so that the fast switching The support 27 on the left side of the upper surface of the platform 12 slides to the left along the slide 26. At this time, the support 27 on both sides realizes automatic avoidance under the interaction of the extrusion rod 28 and the arc-shaped extrusion groove 25. When the L-shaped slides 23 on both sides of the transmission belt 22 slide to the two ends of the slide 24, since the two ends of the slide 24 are equipped with sensor devices, when the L-shaped slide 23 slides to the two ends of the slide 24, the sensor device is started, and the sensor device converts the internal electrical signal and sends it to the controller, so that the motor stops rotating under the control of the controller.

[0057] Since the present invention installs high-precision sensor devices at both ends of the slide 24, and since these sensor devices can accurately control the rotation of the motor through the controller, the double-station internal pressure mold 13 switching design can be used to prepare or replace one internal pressure mold 13 while the other internal pressure mold 13 is being stamped, thereby realizing a continuous and uninterrupted production process. In contrast, the traditional method of fixing the internal pressure mold 13 requires stopping the machine to replace the internal pressure mold 13 after each stamping, resulting in low production efficiency.

[0058] Compared with the single internal pressure mold 13 fixing method adopted in the prior art, the internal pressure mold 13 switching design of the device of the present invention not only reduces the waiting time of the internal pressure mold 13 during the stamping process, but also avoids the overheating and increased wear of the internal pressure mold 13 caused by long-term continuous work. In addition, the operator can realize rapid replacement of the mold after the internal pressure mold 13 is switched, without complicated disassembly and cleaning process, which not only reduces the difficulty of operation, but also reduces equipment damage and downtime caused by improper operation, thereby reducing the risk of damage caused by improper replacement of the internal pressure mold 13.

[0059] Please refer to the above working process Figures 1 to 7 .

[0060] The following is a working process of the automatic positioning anti-deviation mechanism 3 for dust removal on the surface of the hydraulic operating table 1 and automatic positioning of the internal pressure mold 13 before pressing the internal pressure mold 13:

[0061] When in use, when the internal pressure mold 13 switches and starts to gradually slide to the surface of the hydraulic operating table 1, the sliding of the internal pressure mold 13 will push the push plate 31 to start as Figure 6 Slide to the right as shown. Figure 7As shown in the figure, when the push plate 31 slides to the right, since the push plate 31 is fixedly connected to the multifunctional double-sided sliding gear plate 32 on one side away from the internal pressure mold 13, and the multifunctional double-sided sliding gear plate 32 is slidably connected to the sealing chamber 35 at one end away from the push plate 31, when the push plate 31 drives the multifunctional double-sided sliding gear plate 32 to slide to the right, at this time, since the arc surface positioning clamping plates 33 are symmetrically arranged on both sides of the multifunctional double-sided sliding gear plate 32, the middle part of the arc surface positioning clamping plate 33 away from the internal pressure mold 13 is rotatably connected to the hydraulic On the operating table 1, the outer surface circumference of the arc surface positioning clamping plate 33 near one end of the multifunctional double-sided sliding gear plate 32 is provided with sliding teeth, and the tooth surface of the multifunctional double-sided sliding gear plate 32 is meshed with the sliding teeth provided on the arc surface positioning clamping plate 33, so the arc surface positioning clamping plate 33 near the left side of the multifunctional double-sided sliding gear plate 32 starts to rotate clockwise when the multifunctional double-sided sliding gear plate 32 slides to the right, and the arc surface positioning clamping plate 33 located on the right side of the multifunctional double-sided sliding gear plate 32 starts to rotate counterclockwise at the same time;

[0062] At this time, when the L-shaped slide plate 23 drives the internal pressure mold 13 to slide to one end of the slideway 24 close to the hydraulic operating table 1, the motor stops rotating through the control of the controller under the transmission of the electrical signal in the sensor device. At this time, the internal pressure mold 13 begins to stop moving on the hydraulic operating table 1, and at the same time, the arc surface positioning clamping plate 33 slides down on the multifunctional double-sided sliding tooth plate 32, and the two sides of the internal pressure mold 13 are fixed on the upper surface of the hydraulic operating table 1. When the internal pressure mold 13 is positioned on the surface of the hydraulic operating table 1, the automatic fixation of the two sides of the internal pressure mold 13 by the arc surface positioning clamping plate 33 can not only reduce the production interruption and failure caused by uneven force when stamping asymmetric bent parts, which can not only improve the continuity of production, but also reduce the downtime and cost loss caused by equipment failure, but also reduce the need for operators to manually adjust and position the mold, thereby simplifying the operation process, which can not only improve work efficiency, but also reduce the labor intensity of operators;

[0063] At this time, the return spring 34 located above the multifunctional double-sided sliding gear plate 32 begins to be compressed, and because the sealing chamber 35 is provided with an exhaust hole at one end away from the multifunctional double-sided sliding gear plate 32, and the air pressure hose 36 is fixedly connected to the exhaust hole of the sealing chamber 35, and the outer surface of one end of the air pressure hose 36 is fixedly connected to the sealing chamber 35, and the outer surface of the other end of the air pressure hose 36 is fixedly connected to the push plate 31, when the multifunctional double-sided sliding gear plate 32 slides to the right side on the inner wall of the sealing chamber 35 away from the push plate 31, due to the good air tightness, the air pressure inside the sealing chamber 35 is compressed and then discharged through the air pressure hose 36, and the gas is discharged through the air pressure hose 36. After pressurization, it is quickly released. At this time, the impurities on the cleaning strip on the internal pressure mold 13 can be cleaned through the air pressure hose 36. The flow of this gas is not limited to the cleaning strip. It can also clean the surface of the hydraulic operating table 1 to a certain extent, and take away the residues stubbornly attached to the bottom of the internal pressure mold 13 due to high-temperature pressing, thereby ensuring the cleanliness of the production environment and the good operation of the equipment, thereby avoiding the damage that these residues may cause to the internal pressure mold 13 itself during the stamping process of the internal pressure mold 13, which not only improves the production efficiency, but also ensures the long-term service life of the internal pressure mold 13 and the high-quality output of the product.
