DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-4The multi-purpose fully automatic high-strength aluminum alloy forging high-pressure surface treatment device shown is specially used for the surface treatment of demolding forgings. The forgings are subjected to physical reaction treatment and mechanical cleaning in sequence to remove the demolding agent. The chemical treatment is generally carried out by immersing the forgings in a physical property treatment box 4 filled with a reaction liquid, and the active agent in the reaction liquid strips off the demolding agent such as emulsified graphite to achieve preliminary cleaning. The mechanical cleaning generally uses high-pressure water to flush the demolding agent and the reaction liquid on the surface of the forging. Correspondingly, the surface treatment device includes a transfer system 5 and a conveyor line, a physical property treatment box 4 and a spray box 8 arranged in sequence. The bottom of the spray box 8 is equipped with N first positioning seats 7 for placing forgings, and the two side walls of the spray box 8 are provided with a surface cleaning system 6 and a rotating mechanism for driving the first positioning seat 7 to rotate. The surface treatment device can simultaneously perform surface treatment on N forgings in each production cycle, N ≥ 2, and the surface cleaning system 6 includes 2N groups of cleaning nozzle groups, which are fixed on the two box walls of the spray box 8, that is, the two sides of each first positioning seat 7. A cleaning nozzle group is correspondingly arranged on the upper side of the forging, and high-pressure water is sprayed from the upper side of the forging to flush the upper and side surfaces of the forging. The cleaning nozzle group includes a high-pressure nozzle 61 for flushing and cleaning the surface of the forging, a large-flow nozzle 62 for cleaning and removing residues, and an air blowing nozzle 63 for drying the forging. The high-pressure nozzle 61 uses high-pressure water of about 1.2 MPa, and the large-flow nozzle 62 uses low-pressure circulating water with a water pressure of about 0.35-0.5 MPa. The water flow is large, and the water flow is easy to extend to cover the entire For each forging surface, the main control system of the surface treatment device presets the alkali washing time, high-pressure spray washing time, large-flow flushing time and blast drying time. After the forging is alkaline washed, the forging transfer spray box 8 first uses a high-pressure jet to remove the surface release agent and reaction liquid, and then rinses it with a large flow of warm water to take away the release agent and reaction liquid on the forging surface and the spray blind area. Finally, the surface is blown dry by the blowing nozzle 63 connected to the blower. At the same time, the negative pressure fan in the spray box 8 is used to absorb and remove the odor of the surface reaction of the physical properties.

[0025] In order to reduce the blind spot of high-pressure spraying, the forging is rotated during the high-pressure spraying process. The rotating mechanism is arranged directly below the spray box 8, including a rotating cleaning motor 12, a sealing seat, a driving shaft 14, N groups of bevel gear pairs 15 and N transmission shafts 13. N connecting holes are opened at the bottom of the spray box 8. The transmission shaft 13 passes through the connecting holes and is rotatably arranged at the bottom of the spray box 8 through a plane bearing. The two ends of the plane bearing are sealed with a sealing seat and a sealing gasket. The driving shaft 14 is placed horizontally below the bottom of the spray box 8 and is driven by the rotating cleaning motor 12. The driving shaft 14 is equipped with an active bevel gear of N groups of bevel gear pairs 15. The upper end of the transmission shaft 13 is inserted into the connecting groove 73 at the lower end of the first positioning seat 7 and is fixedly connected thereto. The lower end of the transmission shaft 13 is equipped with a driven bevel gear of the bevel gear pair 15. The rotation of the driving shaft 14 drives the N transmission shafts 13 to rotate synchronously at the same time.

[0026] Among them, the transfer system 5 can transfer forgings between multiple workstations according to the sequence of processing procedures, that is, the forgings are automatically transferred between the conveyor line, the physical property treatment box 4 and the spray cleaning box 8. The transfer system 5 can transfer N forgings at a time, which includes a synchronous frame 53, a set of clamping jaws that can hold and carry N forgings at the same time, a clamping jaw driving mechanism 54 that drives the clamping jaws to move relative to each other horizontally to achieve centering, tightening or loosening, a lifting drive device 55 that drives the clamping jaws to lift and lower, and a transfer track 11. The lifting drive device 55 is preferably a lifting cylinder, which is used to lift and lower the forgings into or out of the physical property treatment box 4. The transfer track 11 is arranged across the conveyor line, the physical property treatment box 4 and the spray cleaning box 8 according to the formation needs. The upper end of the synchronous frame 53 is provided with a travel motor 17 that drives it to reciprocate along the transfer track 11. The transfer track 11 can be a double track, one of which is a light rod guide rod and the other is a toothed track or a screw rod. Correspondingly, the travel motor 17 drives the gear connected to the track to move back and forth. The wheel or the screw nut rotates, thereby driving the synchronous frame 53 to move. The synchronous frame 53 includes two cross bars at the upper end, two vertical bars arranged at the two ends of each cross bar, and a mounting frame arranged at the lower end of the vertical bar. The two cross bars are vertically arranged across the double rails and can slide along them. The walking motor 17 is arranged on one of the cross bars, and the lower ends of the four vertical bars are connected to the mounting frame. The clamping jaw pair includes a first clamping jaw 51 and a second clamping jaw 52 of the same structure and symmetrically arranged. Two clamping jaw driving mechanisms 54 are symmetrically arranged between the first clamping jaw 51 and the second clamping jaw 52. The two ends of the clamping jaw driving mechanism 54 are respectively connected to the first clamping jaw 51 and the second clamping jaw 52, ​​which are installed on the mounting frame. The clamping jaw driving mechanism 54 adopts the existing double-sided clamping air jaw structure double-headed cylinder and corresponding air path. The first clamping jaw 51 and the second clamping jaw 52 are respectively fixedly connected to the two piston heads of the double-headed cylinder, wherein the first clamping jaw 51 and the second clamping jaw 52 are two metal plates, and N clamping grooves are linearly and evenly opened on the opposite side end surfaces, such as Figure 1 As shown, the clamping groove can be an arc groove or a V-shaped groove. The clamping jaw driving mechanism 54 drives the two opposite clamping grooves to move toward the center, and clamps the circumferential side surfaces of the forging from both sides toward the center.

[0027] As a further technical solution, the conveyor line includes a loading roller belt line 3 and a unloading roller belt line 1, both of which are arranged at the front end of the physical property processing box 4, and the loading roller belt line 3 is located between the unloading roller belt line 1 and the physical property processing box 4, the loading roller belt line 3 and the unloading roller belt line 1 both include a closed-loop synchronous belt whose surface can convey forgings, and the following description of the synchronous belt, unless otherwise specified, refers to the synchronous belt of the loading roller belt line 3, and the surface of the synchronous belt has a loading area with a length of L and a unloading area with a length of L, L is equal to half of the circumference of the synchronous belt, that is, the synchronous belt is divided into two halves, one half is used for loading and the other half is used for unloading, wherein a plurality of horizontal strips are evenly arranged on the synchronous belt in the loading area for fixedly installing a third positioning seat 10, N third positioning seats 10 are located in the middle of the synchronous belt and are linearly and evenly arranged along the conveying direction, which can be used for the manipulator to place the positionable forgings for easy clamping of the clamping claws, and a clearance gap 2 is provided between the loading roller belt line 3 and the unloading roller belt line 1 to make way for the third positioning seat 10 vertically standing on the surface of the synchronous belt. The synchronous belt of the loading roller belt line 3 is driven by the loading motor 16. When one side of the loading area is located at the upper part, the loading roller belt line 3 is used as the loading line. The forgings can be loaded on the loading roller belt line 3 by a manipulator or manually and positioned on the third positioning seat 10. When one side of the unloading area is located at the upper part, the loading roller belt line 3 is used as the unloading line. The loading motor 16 drives the synchronous belt to drive the forgings to move toward the unloading roller belt line 1, and the forgings are automatically transferred to the unloading roller belt line 1 for centralized unloading. The loading roller belt line 3 and the unloading roller belt line 1 are simultaneously arranged on the same side of the surface treatment process, and the on-site layout and production line planning are highly flexible. Since the forgings require a certain surface treatment time, the operating frequency and utilization rate of the loading roller belt line 3 are low. Therefore, the synchronous belts on both sides are used to realize the dual functions of loading and unloading, which can improve its utilization rate, and the unloading roller belt line 1 can concentrate the forgings after surface treatment, so that the operator can unload at a regular time to reduce the operator's work intensity and time occupancy.

[0028] In order to facilitate the transportation and positioning of forgings, a second positioning seat 9 is also provided at the bottom of the physical property treatment box 4. When the production line is arranged, the forgings of the conveyor line and the cleaning station are located at the same height, and the forgings of the alkali cleaning station are located at the bottom of the physical property treatment box 4, which is lower than the conveyor line. However, the conveyor line, the alkali cleaning station and the cleaning station are all located in the clampable area of ​​the clamping jaw pair, that is, the first positioning seat 7, the second positioning seat 9 and the third positioning seat 10 are located on the same longitudinal plane, that is, the vertical centering clamping surface of the clamping jaw pair, wherein the first positioning seat 7, the second positioning seat 9 and the third positioning seat 10 all include The conical platform 71 and the positioning column 72 on the lower surface of the supporting forging, the positioning column 72 is located on the upper end surface of the conical platform 71, and its axis is colinear with the central axis of the conical platform 71, the positioning column 72 is used to penetrate the central axis hole of the forging, the upper end surface of the conical platform 71 is supported and connected with the edge of the axis hole of the lower end surface of the forging, the first positioning seat 7 is provided with a chassis body 74 to maintain its stability and balance, the second positioning seat 9 is also provided with a chassis body 74, which is used as a flange connected to the bottom of the physical property processing box 4, and the conical platform 71 of the third positioning seat 10 is provided with a bolt countersunk hole 101 to facilitate its connection and fixation with the cross bar.

[0029] like Figure 5As shown, the surface treatment device works and part of the control process is as follows: wherein, the drive control system is connected to the main controller, the main controller controls the opening and closing time and the spray pulse width of each nozzle of the surface cleaning system 6, the opening and closing of the lifting electromagnetic air circuit valve of the lifting drive device 55, the opening and closing of the clamping electromagnetic air circuit control valve, the waste heat heating flushing water system and the negative pressure deodorization system, etc., the drive control system includes an in-place signal, a first receiver connected to the rotating cleaning motor 12, a second receiver connected to the feeding motor 16 and a third receiver connected to the walking motor 17. The in-place signal adopts a photoelectric switch in-place detector. When the clamping jaws run to the corresponding position, the original level voltage of the photoelectric switch in-place detector changes due to light obstruction, thereby realizing weak current control. The in-place signal includes a cleaning station in-place signal arranged in the spray box 8, a positioning device in-place signal arranged in the physical property processing box 4 and a feeding in-place signal arranged on the feeding roller belt line 3. Among them, the cleaning station in-place signal is connected to the RSA and RSB ports of the third receiver through a time relay, and is connected to the KA25 pin of the first receiver to control the rotation. The first receiver is also connected to the high-flow water circuit through Y01 and Y05, and automatically switches the high-flow nozzle 62 for high-flow water flushing when it stops; the third receiver changes the walking direction of the walking motor 17 after receiving the variable frequency signal delayed by the time relay, and at the same time sends a signal to start the clamping jaw drive mechanism 54 to control the clamping electromagnetic air circuit control valve in the air circuit to control the action of the clamping jaws. The alkali cleaning station arrival signal is connected to the third receiver through a low-level trigger power-off relay. When the alkali cleaning station arrival signal is blocked, a low-level signal is sent to make the alkali cleaning station arrive at the signal. The third receiver cuts off the input circuit of the travel motor 17, and sends a signal to the lifting electromagnetic air circuit valve of the lifting drive device 55 to start the lifting action. When it drops to the stroke position, the lifting electromagnetic air circuit valve feedbacks a signal to start the clamping electromagnetic air circuit control valve to control the action of the clamping jaws. The lifting electromagnetic air circuit valve receives the frequency conversion signal and rises back to its original position. Similarly, the material loading signal is connected to the RSA and RSB ports of the second and third receivers through the time relay, respectively, to drive the travel motor 17 to change direction and drive the loading motor 16 to switch the loading area or the unloading area.

[0030] First is the loading work. The clamping jaws are located in the initial position, that is, just above the physical property processing box 4. The clamping jaws first descend to clamp the forgings therein, and then rise to transport them to the cleaning station, triggering the cleaning station arrival signal to send a signal to the first receiver, starting the rotating cleaning motor 12, and sending a reversing signal to the third receiver. The rotating cleaning motor 12 drives the forgings to rotate, and at the same time, the high-pressure nozzle 61 sprays high-pressure water to clean the surface of the forgings. As the high-pressure cleaning is completed, it automatically switches to low-pressure water flushing, and finally blows the surface dry to complete all surface treatment processes. After completing the transportation of the forgings in the cleaning station, the transfer system 5 moves to just above the loading roller belt line 3 through frequency conversion reversing, clamps the forgings in the loading area, and triggers the loading arrival signal to send a reversing signal to the third receiver. At the same time, a signal is sent to the second receiver, and the loading motor 16 switches to the unloading area according to the feedback signal. The loading motor 16 is started and switched to the unloading area, and the travel motor 17 changes direction and moves to the top of the physical property processing box 4. The travel motor 17 stops to discharge the material at the alkali washing station. After completing all surface treatment processes, the transfer system 5 moves to the top of the spray box 8, clamps the cleaned forgings, and triggers the cleaning station in place signal device to send a signal to the third receiver. The travel motor 17 moves in the opposite direction to the loading roller belt line 3 for unloading. After the unloading is completed, the loading motor 16 is started and the forgings are automatically transported to the unloading roller line. This is a complete working cycle. The surface treatment of the forgings is repeated continuously according to this working cycle. Compared with manual processing, the production efficiency of forgings is significantly improved.
