Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal surface processing, in particular to a surface permeation treatment shot peening sorting and recycling device and a sorting method thereof. BACKGROUND

[0002] Surface permeation treatment is a new surface strengthening treatment process, which is to spray the shot peening of the phase layer wrapped with B, N and C elements to the surface of the part through the spraying process, so that the wrapping layer on the surface of the shot peening is embedded into the surface of the part, forming a phase layer containing B, N and C elements on the surface of the part, thereby improving the performance and service life of the workpiece. The high-speed bombardment at low temperature avoids the problems of grain growth and workpiece deformation that may occur in the conventional high-temperature carburizing treatment process. At the same time, the shot peening on the surface of the workpiece has the effect of polishing, which refines the grains on the surface of the part and effectively improves the hardness and yield strength of the workpiece surface.

[0003] However, when using shot peening to strengthen the permeation treatment of the workpiece surface, the surface phase layer of the shot peening will be damaged. For example, after the surface phase layer of the shot peening is embedded into the part, the thickness of the surface phase layer will be reduced, or the surface phase layer of the shot peening is prone to cracking and falling off after strong impact. These situations will cause defects in the surface phase layer of the shot peening. When the ratio of the defect amount of the surface phase layer of the shot peening to the surface area of the shot peening reaches a certain value, the shot peening can no longer be used for surface permeation treatment of the part. Moreover, the shot peening is prone to deformation during impact permeation treatment. When the deformation amount of the shot peening is too large, the shot peening is likely to cause damage to the part. Therefore, shot peenings with a large proportion of surface phase layer defects and shot peenings with a large deformation amount need to be removed. However, the diameter of the shot peening is generally between 1mm and 2mm, and it is difficult to sort manually. In order to prevent unqualified surface permeation treatment, enterprises generally use a batch of shot peenings for several times and then replace the whole batch for remelting. This will cause waste as the good shot peenings are also replaced for remelting.

[0004] The shot peening sorting device on the market generally sorts the deformed shot peenings. For example, a shot peening quality division system according to the shot peening specification disclosed in CN110813758A, by adjusting the relative angle of the two guide sliding rods, the distance between the guide sliding rods of each section is continuously increased from top to bottom, thereby realizing the falling process of the shot peening from small to large, realizing the shot peening quality selection work, and changing the size of the selection range by changing the angle of the guide sliding rod, realizing the multiple fine sorting of the shot peening, and the mechanical integrated sorting and storage structure does not need manual selection, solving the problem of millimeter level shot peening that cannot be easily measured and detected and low efficiency selection. It is unable to sort the shot peening according to the proportion of surface phase layer defects. SUMMARY

[0030] The surface penetration treatment shot sorting and recycling device and the sorting method thereof are as follows:

[0031] S1, input the standard image information of the shot into the central control device 2, and set the surface phase layer defect proportion and the deformation amount when the shot meets the minimum use requirement in the central control device 2, the shot high-speed impacts on the part surface of the part rack 11 for surface penetration treatment, the falling shot falls into the penetration treatment box 1, the blanking electromagnetic valve 13 is opened, part of the shot falls into the screening bin 12, when the number of the shot in the screening bin 12 reaches a certain number, the blanking electromagnetic valve 13 is closed, the vibrating screen 121 screens the shot in the screening bin 12, the initially screened qualified shot falls into the plastic pipe body 14 of the throttling discharge pipe, at this time, the upper distribution electromagnetic valve 141 of the plastic pipe body 14 is opened, the lower distribution electromagnetic valve 141 is closed, the shot falls from the upper distribution electromagnetic valve 141 to the lower distribution electromagnetic valve 141, then the upper distribution electromagnetic valve 141 is closed, at the same time, the rotary telescopic mechanism 38 of the first step-by-step rotary object table 31 at the side wall scanning station 4 drives the electromagnet 39 to move upward until it is attached to the plastic pipe body 14, then the lower distribution electromagnetic valve 141 is opened, the shot in the plastic pipe body 14 falls into the electromagnet 39 at the side wall scanning station 4, the electromagnet 39 generates magnetic force after being electrified, the bottom of the shot is adsorbed on the electromagnet 39, and the top of the shot is exposed outside, then the rotary telescopic mechanism 38 drives the electromagnet 39 and the shot to reset downward to a position horizontally aligned with the first visual detector 41;

[0032] In this step, when all the shot meeting the initial screening regulations on the vibrating screen 121 fall below the vibrating screen 121, the vibrating screen 121 stops vibrating, the shot with large distortion is left on the vibrating screen 121, the discharge electromagnetic valve 122 on the screening bin 12 is opened, the pushing cylinder 123 pushes the shot left on the vibrating screen 121 to the direction of the discharge electromagnetic valve 122, the shot with large distortion falls from the discharge electromagnetic valve 122 into the inclined conveying pipe 124, and then rolls into the waste bin 813 by gravity, after the pushing is completed, the pushing cylinder 123 is reset, the discharge electromagnetic valve 122 is closed, and the discharge electromagnetic valve 13 is opened to re-discharge;

[0033] S2, the rotary telescopic mechanism 38 at the side wall scanning station 4 drives the electromagnet 39 and the shot to rotate horizontally, the first visual detector 41 scans the shot once every 95° of horizontal rotation, and the first visual detector 41 completes the scanning of the side wall of the shot after the shot rotates four times, and then saves the side wall image information of the shot into the central control device 2, and the reason why scanning is performed once every 95° of rotation is to check and correct the side wall image information of the shot according to the overlapping part when processing the side wall image information of the shot, so as to improve the accuracy of scanning;

[0034] S3, the first step rotary loading platform 31 transfers the shot to the top scanning station 5, at this time, the top of the shot faces downward, the second visual detector 51 at the top scanning station 5 scans the top of the shot upward, and then saves the top image information of the shot into the central control device 2, and the second visual detector 5 scans the part of the side wall image close to the top when scanning the top of the shot;

[0035] S4, the first step motorized rotary stage 31 moves the shot to the transfer station 6, the rotary telescopic mechanism 38 on the second step motorized rotary stage 32 at the transfer station 6 drives the corresponding electromagnet 39 to extend and abut against the top of the shot at the transfer station 6, the electromagnet 39 at the transfer station 6 on the second step motorized rotary stage 32 is powered to generate magnetic force to adsorb the shot at the station, the magnetic poles of the electromagnet 39 on the first step motorized rotary stage 31 and the magnetic poles of the electromagnet 39 on the second step motorized rotary stage 32 are opposite, so that the two electromagnets 39 do not repel each other, the electromagnet 39 at the transfer station 6 on the first step motorized rotary stage 31 is de-energized and loses magnetism, the electromagnet 39 at the transfer station 6 on the second step motorized rotary stage 32 is retracted under the action of the rotary telescopic mechanism 38, at this time, the top of the shot is in contact with the electromagnet 39 on the second step motorized rotary stage 32, so that the shot is adsorbed by the electromagnet 39 on the second step motorized rotary stage 32, the bottom of the shot is exposed, the second step motorized rotary stage 32 moves the shot to the bottom scanning station 7, the third visual detector 71 at the bottom scanning station 7 scans the bottom of the shot upward, then saves the bottom image information of the shot to the central control device 2, the third visual detector 71 scans part of the side wall image near the bottom when scanning the bottom of the shot;

[0036] S5, the central control device 2 splices the side wall image information, the top image information and the bottom image information, when splicing, the top image information and the bottom image information both have part of the side wall image information overlapping, then the top image information, the side wall image information and the bottom image information are corrected according to the overlapping part, so as to obtain accurate variable image information, the central control device 2 calculates the surface phase defect proportion of the shot through the variable image information, then compares the variable image information with the standard image information of the shot through image superposition, then calculates the coincidence degree of the outer side edges between the variable image information and the standard image information;

[0037] In this step, since the shot with large distortion variable is removed in step S1, but some shots with variable elliptical shape will still fall from the vibrating screen 121, so it is necessary to use the image superposition comparison method to sort out these shots with variable elliptical shape;

[0038] S6, the second step of the rotation stage 32 is transferred to the shot to the drop site 8, if the shot surface phase layer defect ratio is less than the set value, and the degree of coincidence between the standard image information is not less than 85%, indicating that the shot can be directly recycled, it is sent to the material warehouse 812, if the shot surface phase layer defect ratio is less than the set value, and the degree of coincidence between the standard image information is less than 85%, indicating that the shot deformation is larger, not suitable for reuse, it needs to be sent to the waste warehouse 813 for remelting; if the shot surface phase layer defect ratio is greater than the set value, and the degree of coincidence between the standard image information is not less than 85%, indicating that the shot needs to be reset after the shot is used, it needs to be sent to the reset warehouse 811, if the shot surface phase layer defect ratio is greater than the set value, and the degree of coincidence between the standard image information is less than 85%, indicating that the shot deformation is larger, not suitable for reuse, it needs to be sent to the waste warehouse 813 for remelting.
