Description

Technical Field

[0001] The present invention relates to the technical field of shaping machines, and in particular to a shaping machine with feeding deviation correction. Background Art

[0002] In the fields of hardware stamping, plastic molding, electronic component processing, etc., shaping machines are widely used as key processing equipment. The stability of their feeding systems directly affects production efficiency. Traditional shaping machines generally adopt manual feeding methods, relying on operators to manually place workpieces. However, with the popularization of vibratory bowl feeding technology, more and more factories are now using vibratory bowls to convey workpieces.

[0003] However, the following problems still exist in the actual use of existing automatic conveying shaping machines: For example, currently, vibratory bowls often achieve workpiece orientation through track vibration. However, when discharging, due to inertia, workpieces often output in a tight queue. Traditional shaping machines usually use fixed dial rods and other methods to separate workpieces. However, this separation method, on the one hand, cannot automatically adjust the misalignment amplitude according to the workpiece size, and on the other hand, when the workpiece position deviates, it often requires manual deviation correction of the workpiece after stopping the machine, thereby affecting work efficiency. In addition, as the core power component of the shaping machine, the stability of its hydraulic drive system determines the processing accuracy. Currently, the hydraulic drive systems of shaping machines usually directly adopt direct drive methods such as springs for resetting. When the liquid pump suddenly fails or encounters power outages and other situations, the hydraulic drive system is prone to cause severe hydraulic shocks during the reset process, resulting in problems such as noise pollution and component damage, thereby affecting subsequent processing. Summary of the Invention

[0004] The purpose of the present invention is to provide a shaping machine with feeding deviation correction to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solution: A shaping machine with feeding and deviation correction. The shaping machine includes a machine body and a vibrating bowl. A workbench is provided on the machine body. A shaping die is provided at the middle position above the workbench. A clamping mechanism is provided above the shaping die. The clamping mechanism is connected to the workbench through a handling module. The vibrating bowl is arranged outside the machine body to achieve the purpose of automatic feeding. An oil press is also provided on the machine body. A shaping die head is provided at the working end of the oil press. Compared with the current shaping machine, the present invention is provided with a misalignment mechanism. The misalignment mechanism is arranged on one side of the shaping die close to the vibrating bowl. The vibrating bowl is connected to the misalignment mechanism through a conveying rack. When the vibrating bowl sequentially conveys the workpieces to the vicinity of the misalignment mechanism, the misalignment mechanism causes the workpieces to have a lateral or longitudinal position offset during discharging, so as to destroy the tightly arranged state, ensure the orderly separation of individual workpieces, avoid blocking the discharge port or affecting the subsequent processes, and facilitate the handling module and the clamping mechanism to move the separated individual workpieces onto the shaping die. In addition, the misalignment mechanism in the present invention can correct the deviation and position of workpieces with different sizes. On the one hand, it avoids the need to replace a new misalignment mechanism every time processing workpieces with different sizes, and on the other hand, it ensures that the clamping mechanism can accurately clamp the workpiece, preventing the clamping mechanism from clamping skew, thereby causing damage to the workpiece or the workpiece falling off during the movement process. Finally, after the workpiece is placed on the shaping die, the oil press drives the shaping die head to descend, and the workpiece is shaped under the dual action of the shaping die head and the shaping die.

[0006] Further, a screening mechanism is provided at one end of the vibrating bowl close to the conveying rack. The screening mechanism screens the workpieces that do not meet the requirements to avoid unqualified products or workpieces with incorrect postures from flowing into the subsequent production line, thereby improving production efficiency. A mold-in monitor is provided at the side end of the misalignment mechanism. On the one hand, the mold-in monitor real-time monitors the operating state, workpiece arrangement quality and abnormal conditions of the misalignment mechanism to ensure the stability of the shaping machine and subsequent processes and the product quality. On the other hand, the mold-in monitor monitors the workpiece shaping scenario to prevent the workpiece from not being demolded in time or foreign objects from entering the mold cavity, avoiding mold damage and workpiece defects caused by abnormal reasons.

[0007] Further, the clamping mechanism includes a support frame, a first cylinder, clamping jaws and a lifting module. The support frame is connected to the handling module, and the handling module drives the support frame to move horizontally. The lifting module is arranged below the support frame. The first cylinder is arranged at the side end of the lifting module. The clamping jaws are arranged at the side end of the first cylinder. The lifting module drives the first cylinder and the clamping jaws to move up and down, and the first cylinder drives the clamping jaws to approach or move away from each other so as to clamp the workpiece.

[0008] Furthermore, the dislocation mechanism includes a first mounting frame and a second mounting frame, the second mounting frame is arranged at one end of the first mounting frame close to the conveying frame, the second mounting frame is provided with a first storage slot, the first mounting frame is provided with a second cylinder and a dislocation frame, the dislocation frame is provided with a second storage slot at one end close to the second mounting frame, the second storage slot is adapted to the first storage slot, the conveying frame in the present invention is aligned with the first storage slot, and when the vibrating plate and the conveying frame convey the workpiece into the first storage slot, the dislocation frame is driven by the second cylinder to move on the first mounting frame, and when the second storage slot When the slot is aligned with the first storage slot, the workpiece can be moved smoothly from the first storage slot to the second storage slot. Subsequently, the second cylinder continues to move, driving the offset frame to move horizontally along the first mounting frame, so that the second storage slot is staggered with the first storage slot by a certain distance, thereby realizing the staggered arrangement of the workpieces. Through the above technical solution, it is ensured that individual workpieces can be separated in an orderly manner, which facilitates the subsequent clamping mechanism to accurately clamp the workpiece. After the clamping mechanism clamps the workpiece in the second storage slot away, the second cylinder can continue to move to align the second storage slot with the first storage slot, so that the new workpiece enters the second storage slot.

[0009] Furthermore, the width of the first storage slot and the second storage slot is greater than the width of the conveying rack, and a group of positioning airbags are provided on the left and right side walls of the second storage slot, and the positioning airbags are connected to an external air pump. When the workpiece in the first storage slot moves into the second storage slot, the two groups of positioning airbags in the second storage slot are in a contracted state, so as to facilitate the smooth movement of the workpiece into the second storage slot. When the workpiece completely enters the second storage slot, the same amount of compressed gas is delivered to the two groups of positioning airbags in the second storage slot through the external air pump. At this time, the two groups of positioning airbags will expand to the same extent. Under the action of the two groups of positioning airbags, the workpiece will be clamped in the center position of the second storage slot to facilitate the subsequent clamping mechanism to clamp the workpiece. Finally, when there is a slight offset in the workpiece, the symmetrical pressure generated by the positioning airbags on both sides will push the workpiece to automatically return to its position, completing the correction action, and ensuring that its axis is completely aligned with the processing reference of the subsequent process.

[0010] Further, the hydraulic press includes a movable seat, a fixed seat and a lift. The fixed seat is fixedly installed at the top of the fuselage through a guide rod. The movable seat is arranged between the fixed seat and the workbench. The shaping die head is arranged at the lower end of the movable seat. The lift is arranged at the middle position of the fixed seat. A lift cavity and a lift rod are arranged inside the lift. The lift rod is arranged in the lift cavity and is connected to the movable seat. A control box and a liquid pump are arranged at the upper side end of the fixed seat. The liquid pump is connected to the top end of the lift cavity through a first channel. A reset mechanism is arranged on one side of the control box close to the lift. The reset mechanism is connected to the bottom end of the lift cavity through a second channel. In the present invention, hydraulic oil is added to the lift cavity. Under the dual action of the liquid pump and the reset mechanism, the lift rod and the movable seat are driven to make a lifting motion above the workbench, so as to realize the subsequent workpiece shaping operation.

[0011] Further, the reset mechanism includes a liquid storage tank. A slide rod is arranged inside the liquid storage tank. A movable plug and a first compression spring are arranged on the slide rod. An activity groove is arranged at the lower end inside the liquid storage tank. A protection component is arranged in the activity groove. A first through hole is arranged on one side of the activity groove close to the movable plug. A sealing end cover is arranged on the side of the activity groove away from the movable plug. A third through hole is arranged on the sealing end cover. The third through hole is aligned with the first through hole. The third through hole is connected to the bottom end of the lift cavity through an infusion tube and a second channel. When it is necessary to lower the lift rod and the movable seat, the liquid pump will convey hydraulic oil to the upper end of the lift cavity. Under the action of the hydraulic pressure, the lift rod and the movable seat will descend. At the same time, the hydraulic oil at the lower end of the lift cavity will enter the liquid storage tank. When it is necessary to raise the lift rod and the movable seat, the liquid pump will pump out the hydraulic oil at the upper end of the lift cavity. Under the action of the movable plug and the first compression spring in the liquid storage tank, the stored hydraulic oil in the liquid storage tank will enter the lower end of the lift cavity. At this time, the lift rod and the movable seat will rise. Compared with the hydraulic drive system used in the current shaping machine, the present invention is provided with a protection component. When the liquid pump fails or power is cut off, etc., the lift rod and the movable seat can be reset to be away from the workbench through the protection component, avoiding the problem that the workpiece stays in the shaping die and the shaping die head due to equipment failure. Moreover, since the shaping die head and the shaping die are separated in time, it can also effectively avoid the wear and deformation of the die caused by long-term extrusion.

[0012] Further, the protection component includes an electromagnet and a current-limiting block. The current-limiting block is movably installed in the activity groove through a second compression spring. A second through hole is arranged on the current-limiting block. A magnetic block is embedded at one end of the current-limiting block close to the electromagnet.

[0013] Further, a pressure relief groove is also arranged inside the lift. The pressure relief groove is connected to the lift cavity through an electromagnetic valve.

[0014] In the present invention, both the electromagnet and the solenoid valve are connected to the liquid pump. During normal operation, both the electromagnet and the solenoid valve are in the open state. The electromagnet magnetically attracts the current-limiting block so that the second through-hole on the current-limiting block is completely aligned with the third through-hole and the first through-hole. The solenoid valve makes the pressure relief groove and the lifting cavity in a non-connected state. When the liquid pump fails or power is cut off, both the electromagnet and the solenoid valve are in the closed state. At this time, under the action of the second compression spring, the current-limiting block moves away from the electromagnet so that the second through-hole on the current-limiting block is partially aligned with the third through-hole and the first through-hole, and the pressure relief groove is in communication with the lifting cavity. Under the action of the movable plug and the first compression spring in the liquid storage tank, the hydraulic oil stored in the liquid storage tank slowly enters the lower end of the lifting cavity. Under the action of the hydraulic pressure, the lifting rod and the movable seat rise, and the hydraulic oil at the upper end of the lifting cavity enters the pressure relief groove. Through the above technical solution, the lifting rod and the movable seat are reset to move away from the workbench. Compared with the current reset method of the hydraulic drive system, the present invention realizes the "controllable slow flow" of the hydraulic oil by controlling the overlapping area of the second through-hole, the third through-hole and the first through-hole on the current-limiting block, effectively avoiding the problem of pressure mutation caused by too fast flow rate in the traditional reset method, preventing the hydraulic components from vibrating, making noise and wearing due to the instantaneous impact force when the hydraulic oil in the liquid storage tank flows back to the lifting cavity, and significantly prolonging the service life of the internal hydraulic components of the hydraulic press.

[0015] Furthermore, a magnetic filter cartridge is arranged inside the second through-hole. The magnetic filter cartridge is connected to the second through-hole by a thread. A threaded hole is arranged on the side of the third through-hole away from the electromagnet, and a threaded plug is arranged in the threaded hole. When the present invention is working, the hydraulic oil will circulate through the magnetic filter cartridge, and the magnetic filter cartridge adsorbs ferromagnetic impurities in the oil to reduce the wear of the internal hydraulic components of the hydraulic press during operation. When the present invention is in a non-working state, the staff can generate a magnetic field that repels the current-limiting block through the electromagnet so that the second through-hole on the current-limiting block is aligned with the threaded hole on the sealing end cover. Then the staff can take out the threaded plug from the threaded hole. At this time, by rotating the magnetic filter cartridge, the staff can take out the magnetic filter cartridge from the second through-hole to replace it with a new magnetic filter cartridge. Through the above technical solution, the present invention realizes the rapid replacement and maintenance of the magnetic filter cartridge, significantly improving the convenience of maintaining the hydraulic system.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. Compared with the current shaping machine, the present invention is provided with a dislocation mechanism. After the workpiece exits the conveying rack, the dislocation mechanism causes the workpiece to have a lateral position offset to disrupt the closely arranged state, ensuring the orderly separation of individual workpieces, facilitating the handling module and the clamping mechanism to move the separated individual workpieces to the shaping die. In addition, on the one hand, the dislocation mechanism in the present invention can complete the rapid switching of workpieces of different models without replacing hardware, avoiding the need to replace a new dislocation mechanism every time workpieces of different models are processed. On the other hand, when the workpiece is offset, the dislocation mechanism can correct the deviation and position the workpiece to ensure that its axis is completely aligned with the processing reference of the subsequent process, facilitating the clamping mechanism to accurately clamp the workpiece;

[0018] 2. The present invention is provided with a reset mechanism and a protection component, effectively improving the reliability of the shaping machine. When the liquid pump fails or power is cut off, through the cooperation of the reset mechanism and the protection component, "controlled slow flow" of the hydraulic oil is achieved, effectively avoiding the pressure mutation problem caused by too fast flow rate in the traditional reset method, preventing the hydraulic components from vibrating, generating noise and wearing due to the instantaneous impact force during the process of the hydraulic oil in the liquid storage tank flowing back to the lifting cavity, significantly extending the service life of the hydraulic components inside the hydraulic press. At the same time, a magnetic filter cartridge is provided at one end of the liquid storage tank close to the protection component. The magnetic filter cartridge adsorbs ferromagnetic impurities in the oil in real time, significantly reducing the wear of the hydraulic components inside the hydraulic press. The magnetic filter cartridge adopts threaded connection and magnetic control alignment technology. In the non-working state, the replacement channel is aligned by the repulsive force of the electromagnet, significantly improving the maintenance convenience of the hydraulic system;

[0019] 3. The present invention is also provided with a screening mechanism and an in-mold monitor. The screening mechanism screens workpieces that do not meet the requirements to avoid unqualified products or workpieces with incorrect postures from flowing into the subsequent production line, thereby improving production efficiency. Through the in-mold monitor, on the one hand, it monitors the operating state of the dislocation mechanism, the arrangement quality of workpieces and abnormal situations in real time to ensure the stability of the shaping machine and subsequent processes and product quality. On the other hand, it monitors the workpiece shaping scenario through the in-mold monitor to prevent the workpiece from not being demolded in time or foreign objects from entering the mold cavity, avoiding mold damage and workpiece defects caused by abnormal reasons.

Specific embodiments

[0032] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment: As Figures 1-11As shown in the figure, the present invention provides a technical solution, a shaping machine with feeding and deviation rectification. The shaping machine includes a machine body 1 and a vibrating bowl 2. A workbench 11 is arranged on the machine body 1. A shaping die 12 is arranged at the middle position above the workbench 11. A clamping mechanism 13 is arranged above the shaping die 12. The clamping mechanism 13 is connected to the workbench 11 through a handling module 14. The vibrating bowl 2 is arranged outside the machine body 1 to achieve the purpose of automatic feeding. An oil press is also arranged on the machine body 1. A shaping die head 31 is arranged at the working end of the oil press. Compared with the current shaping machine, the present invention is provided with a dislocation mechanism 21. The dislocation mechanism 21 is arranged on one side of the shaping die 12 close to the vibrating bowl 2. The vibrating bowl 2 is connected to the dislocation mechanism 21 through a conveying frame 23. When the vibrating bowl 2 sequentially conveys the workpieces to the vicinity of the dislocation mechanism 21, the dislocation mechanism 21 causes the workpieces to have a lateral or longitudinal position offset during discharging to destroy the closely arranged state, ensure the orderly separation of individual workpieces, avoid blocking the discharge port or affecting subsequent processes, and facilitate the handling module 14 and the clamping mechanism 13 to move the separated individual workpieces to the shaping die 12. In addition, the dislocation mechanism 21 in the present invention can rectify and position workpieces of different sizes. On the one hand, it avoids the need to replace a new dislocation mechanism 21 every time processing workpieces of different sizes. On the other hand, it ensures that the clamping mechanism 13 can accurately clamp the workpieces, prevent the clamping mechanism 13 from clamping obliquely, and further prevent the workpieces from being damaged or falling off during the moving process. Finally, after the workpiece is placed on the shaping die 12 in the present invention, the oil press drives the shaping die head 31 to descend, and the workpiece is shaped under the dual action of the shaping die head 31 and the shaping die 12.

[0034] As Figures 1-4 shown, a screening mechanism 22 is arranged at one end of the vibrating bowl 2 close to the conveying frame 23. The screening mechanism 22 screens the workpieces that do not meet the requirements to avoid unqualified products or workpieces with incorrect postures from flowing into the subsequent production line, thereby improving production efficiency. An in-mold monitor is arranged at the side end of the dislocation mechanism 21. On the one hand, the in-mold monitor monitors the operating state, workpiece arrangement quality and abnormal conditions of the dislocation mechanism 21 in real time to ensure the stability of the shaping machine and subsequent processes and the product quality. On the other hand, the in-mold monitor monitors the workpiece shaping scenario to prevent the workpieces from not being demolded in time or foreign objects from entering the mold cavity, and avoid mold damage and workpiece defects caused by abnormal reasons.

[0035] As Figure 2 、 Figure 6As shown, the clamping mechanism 13 includes a support frame 131, a first cylinder 132, a clamping jaw 133 and a lifting module 134. The support frame 131 is connected to the transport module 14, and the transport module 14 drives the support frame 131 to move horizontally. The lifting module 134 is arranged below the support frame 131, the first cylinder 132 is arranged at the side end of the lifting module 134, and the clamping jaw 133 is arranged at the side end of the first cylinder 132. The first cylinder 132 and the clamping jaw 133 are driven to move up and down by the lifting module 134, and the clamping jaws 133 are driven to move closer to or away from each other by the first cylinder 132, so that the clamping jaws 133 clamp the workpiece.

[0036] like Figure 2 、 Figure 5 、 Figure 7 As shown, the dislocation mechanism 21 includes a first mounting frame 211 and a second mounting frame 212, the second mounting frame 212 is arranged at one end of the first mounting frame 211 close to the conveying frame 23, the second mounting frame 212 is provided with a first storage groove 213, the first mounting frame 211 is provided with a second cylinder 214 and a dislocation frame 215, the dislocation frame 215 is provided with a second storage groove 2151 at one end close to the second mounting frame 212, the second storage groove 2151 is adapted to the first storage groove 213, the conveying frame 23 in the present invention is aligned with the first storage groove 213, and when the vibrating plate 2 and the conveying frame 23 convey the workpiece to the first storage groove 213, the dislocation frame 215 is driven by the second cylinder 214 to move on the first mounting frame 211, and when the second storage groove 215 is driven When the slot 2151 is aligned with the first storage slot 213, the workpiece can be smoothly moved from the first storage slot 213 to the second storage slot 2151. Subsequently, the second cylinder 214 continues to move, driving the offset frame 215 to move horizontally along the first mounting frame 211, so that the second storage slot 2151 is staggered with the first storage slot 213 by a certain distance, thereby realizing the staggered arrangement of the workpieces. Through the above technical solution, it is ensured that individual workpieces can be separated in an orderly manner, which facilitates the subsequent clamping mechanism 13 to accurately clamp the workpiece. After the clamping mechanism 13 clamps the workpiece in the second storage slot 2151, the second cylinder 214 can continue to move, so that the second storage slot 2151 is aligned with the first storage slot 213, so that the new workpiece enters the second storage slot 2151.

[0037] like Figure 7As shown, the width of the first storage slot 213 and the second storage slot 2151 is greater than the width of the conveying rack 23. A set of positioning airbags 2152 are provided on the left and right side walls of the second storage slot 2151. The positioning airbags 2152 are connected to an external air pump. When the workpiece in the first storage slot 213 moves into the second storage slot 2151, the two groups of positioning airbags 2152 in the second storage slot 2151 are in a contracted state, so as to facilitate the workpiece to smoothly move into the second storage slot 2151. When the workpiece completely enters the second storage slot 2151, the external air pump conveys the same amount of compressed gas to the two groups of positioning airbags 2152 in the second storage slot 2151. At this time, the two groups of positioning airbags 2152 will expand by the same amplitude. Under the action of the two groups of positioning airbags 2152, the workpiece will be clamped at the central position of the second storage slot 2151 to facilitate the subsequent clamping mechanism 13 to clamp the workpiece. Finally, when the workpiece has a slight deviation, the symmetrical pressure generated by the two side positioning airbags 2152 will push the workpiece to automatically return to its position, completing the deviation correction action and ensuring that its axis is completely aligned with the processing reference of the subsequent process.

[0038] As Figure 1 、 Figures 8-10 shown, the hydraulic press includes a movable seat �, a fixed seat 4, and a lifter 5. The fixed seat 4 is fixedly installed at the top of the fuselage 1 through a guide rod. The movable seat 3 is arranged between the fixed seat 4 and the workbench 11. The shaping die head 31 is arranged at the lower end of the movable seat 3. The lifter 5 is arranged at the middle position of the fixed seat 4. An elevating cavity and an elevating rod 54 are arranged inside the lifter 5. The elevating rod 54 is arranged in the elevating cavity and is connected to the movable seat 3. A control box and a liquid pump 41 are arranged at the upper side end of the fixed seat 4. The liquid pump 41 is connected to the top end of the elevating cavity through a first channel 52. A reset mechanism is arranged on one side of the control box close to the lifter 5. The reset mechanism is connected to the bottom end of the elevating cavity through a second channel 53. In the present invention, hydraulic oil is added to the elevating cavity. Through the dual action of the liquid pump 41 and the reset mechanism, the elevating rod 54 and the movable seat 3 are driven to perform lifting movements above the workbench 11, thereby realizing the subsequent workpiece shaping operation.

[0039] As Figures 9-11As shown, the reset mechanism includes a liquid storage tank 42. A slide bar 421 is arranged inside the liquid storage tank 42. An active plug 422 and a first compression spring are arranged on the slide bar 421. An active slot 429 is arranged at the lower end inside the liquid storage tank 42. A protection component is arranged inside the active slot 429. A first through hole 424 is arranged on one side of the active slot 429 close to the active plug 422. A sealing end cover 428 is arranged on the side of the active slot 429 far from the active plug 422. A third through hole 426 is arranged on the sealing end cover 428. The third through hole 426 is aligned with the first through hole 424. The third through hole 426 is connected to the bottom end of the lifting cavity through a liquid delivery pipe and a second channel 53. When it is necessary to lower the lifting rod 54 and the active seat 3, the liquid pump 41 will deliver hydraulic oil to the upper end of the lifting cavity. Under the action of the hydraulic pressure, the lifting rod 54 and the active seat 3 will descend. At the same time, the hydraulic oil at the lower end of the lifting cavity will enter the liquid storage tank 42. When it is necessary to raise the lifting rod 54 and the active seat 3, the liquid pump 41 will pump out the hydraulic oil at the upper end of the lifting cavity. Under the action of the active plug 422 and the first compression spring in the liquid storage tank 42, the hydraulic oil stored in the liquid storage tank 42 will enter the lower end of the lifting cavity. At this time, the lifting rod 54 and the active seat 3 will rise. Compared with the hydraulic drive system used in the current shaping machine, the present invention is provided with a protection component. When the liquid pump 41 fails or a power failure occurs, etc., the lifting rod 54 and the active seat 3 can be reset to move away from the workbench 11 through the protection component, avoiding the problem that the workpiece stays in the shaping die 12 and the shaping die head 31 due to equipment failure. Moreover, since the shaping die head 31 and the shaping die 12 are separated in time, it can also effectively avoid the wear and deformation of the die caused by long-term extrusion.

[0040] As Figures 10-11 shown, the protection component includes an electromagnet 423 and a current-limiting block 425. The current-limiting block 425 is movably installed in the active slot 429 through a second compression spring. A second through hole 4251 is arranged on the current-limiting block 425. A magnetic block is embedded at one end of the current-limiting block 425 close to the electromagnet 423.

[0041] As Figure 9 shown, a pressure relief slot 51 is further arranged inside the elevator 5. The pressure relief slot 51 is connected to the lifting cavity through an electromagnetic valve.

[0042] In the present invention, the electromagnet 423 and the solenoid valve are both connected to the liquid pump 41. During normal operation, both the electromagnet 423 and the solenoid valve are in the open state. The electromagnet 423 magnetically attracts the current-limiting block 425, so that the second through-hole 4251 on the current-limiting block 425 is completely aligned with the third through-hole 426 and the first through-hole 424. The solenoid valve makes the pressure relief groove 51 not communicate with the lifting cavity. When the liquid pump 41 fails or power is cut off, etc., both the electromagnet 423 and the solenoid valve are in the closed state. At this time, under the action of the second compression spring, the current-limiting block 425 moves away from the electromagnet 423, so that the second through-hole 4251 on the current-limiting block 425 is partially aligned with the third through-hole 426 and the first through-hole 424, and the pressure relief groove 51 communicates with the lifting cavity. Under the action of the movable plug 422 and the first compression spring in the liquid storage tank 42, the hydraulic oil stored in the liquid storage tank 42 slowly enters the lower end of the lifting cavity. Under the action of the hydraulic pressure, the lifting rod 54 and the movable seat 3 rise, and the hydraulic oil at the upper end of the lifting cavity enters the pressure relief groove 51. Through the above technical solution, the lifting rod 54 and the movable seat 3 are reset to move away from the workbench 11. Compared with the current reset method of the hydraulic drive system, the present invention realizes the "controllable slow flow" of the hydraulic oil by controlling the overlapping area of the second through-hole 4251 on the current-limiting block 425 with the third through-hole 426 and the first through-hole 424, effectively avoiding the problem of pressure mutation caused by too fast flow rate in the traditional reset method, preventing the hydraulic components from vibrating, making noise and wearing due to the instantaneous impact force when the hydraulic oil in the liquid storage tank 42 flows back to the lifting cavity, and significantly prolonging the service life of the internal hydraulic components of the hydraulic press.

[0043] As Figures 10-11 shown, a magnetic filter cartridge is provided inside the second through-hole 4251. The magnetic filter cartridge is threadedly connected to the second through-hole 4251. A threaded hole is provided on the side of the third through-hole 426 away from the electromagnet 423, and a threaded plug 427 is provided in the threaded hole. When the present invention is working, the hydraulic oil will circulate through the magnetic filter cartridge, and the magnetic filter cartridge adsorbs ferromagnetic impurities in the oil to reduce the wear of the internal hydraulic components of the hydraulic press during operation. When the present invention is in a non-working state, the staff can generate a magnetic field that repels the current-limiting block 425 through the electromagnet 423, so that the second through-hole 4251 on the current-limiting block 425 is aligned with the threaded hole on the sealing end cover 428. Then the staff can take out the threaded plug 427 from the threaded hole. At this time, by rotating the magnetic filter cartridge, the staff can take the magnetic filter cartridge out of the second through-hole 4251 to replace it with a new magnetic filter cartridge. Through the above technical solution, the present invention realizes the rapid replacement and maintenance of the magnetic filter cartridge, and significantly improves the convenience of maintaining the hydraulic system.

[0044] Working principle of the present invention: During operation, the vibrating disk 2 conveys the workpieces to the first storage groove 213 in sequence. The second cylinder 214 drives the dislocation frame 215 to move on the first mounting frame 211. When the second storage groove 2151 is aligned with the first storage groove 213, the workpiece can smoothly move from the first storage groove 213 to the second storage groove 2151. Subsequently, the same amount of compressed gas is conveyed to the two positioning air bags 2152 in the second storage groove 2151 by an external air pump, so that the workpiece is clamped at the central position of the second storage groove 2151. Then, the second cylinder 214 continues to act, driving the dislocation frame 215 to move horizontally along the first mounting frame 211 to stagger the second storage groove 2151 from the first storage groove 213 by a certain distance. After the workpieces are dislocated, the handling module 14 and the clamping mechanism 13 move the separated individual workpieces to the shaping die 12. The shaping die head 31 is driven to descend by the hydraulic press, and the workpiece is shaped under the dual action of the shaping die head 31 and the shaping die 12. During the shaping process, if the liquid pump 41 fails or there is a power outage, etc., under the action of the second compression spring, the current-limiting block 425 will move away from the electromagnet 423, and the pressure relief groove 51 will be in communication with the lifting cavity. At this time, the hydraulic oil stored in the liquid storage tank 42 will slowly enter the lower end of the lifting cavity, and under the action of the hydraulic pressure, the lifting rod 54 and the movable seat 3 will rise, and the shaping die head 31 and the shaping die 12 will be separated in time to facilitate the staff to take out the workpiece and repair the equipment.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
