[0050] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.

[0051] A processing method for producing snap buttons using a cutting device, the processing method comprising the following steps:

[0052] S1: feeding and stamping: placing a metal strip under a stamping device to punch out a snap-on model, punching out a plurality of snap-on models at a time, and the connecting direction of the plurality of snap-on models is inclined to the length direction of the metal strip.

[0053] The metal strip is placed under a stamping setting, and the stamping setting cooperates with the mold to punch out snaps on the metal strip; during stamping, a row of snaps of a corresponding number are formed by a plurality of punches at one time, and the connecting line of the plurality of snaps formed at one time is inclined to the length direction of the metal strip. Therefore, compared with snaps arranged in an ordinary matrix, the snaps of such a stamping setting can punch out more snaps when using the same length of metal strip, thereby increasing the number of snaps, reducing the material loss of the metal strip, and reducing the production cost.

[0054] S2: Cooling down the stamped metal strip.

[0055] The stamped metal strip is immersed in the coolant and covered with the coolant, thereby improving the temperature rise of the metal strip caused by stamping and preventing the metal strip from being too hot when entering the punching device 3, thereby preventing the punched metal snaps from being thermally deformed.

[0056] S3: feeding and cutting: the stamped metal strip is loaded into the positioning device 2, the positioning device 2 is used to drive the metal strip to be positioned, the pushing device 4 is used to drive the metal strip to move forward intermittently, and when the positioning device 2 is used to drive the metal strip to be positioned, the punching device 3 punches the metal strip during the reciprocating motion.

[0057] During the feeding and cutting process, since the punching device 3 has only one processing head for punching, in order to ensure that the snaps on the metal strip can be punched out, a positioning device 2 is required to position the metal strip so that the punching head on the punching device 3 can be aligned with each snap on the metal strip; intermittent pushing of the material by the pushing device 4 can meet the requirement of intermittent advancement of the metal strip; while the positioning device 2 drives the metal strip to move back and forth, the punching device 3 performs punching, thereby speeding up the production of the snaps.

[0058] S4: Grind and curl the edges of the punched buttons.

[0059] After the snap buttons are punched out, the edges of the snap buttons need to be grinded and curled to reduce the sharpness of the punched snap button edges.

[0060] S5: Inspection and sorting: The punched snaps are visually inspected and defective snaps are sorted out based on the inspection results.

[0061] The visual inspection of the press buttons after punching can detect unqualified press buttons, so that the press buttons can be sorted out to increase the qualified rate of the finished press button products.

[0062] S6: Finished product collection: collect the finished snap buttons.

[0063] Collect the finished snaps for centralized processing.

The driving motor 51 is connected to the driving shaft 52, so that the driving motor 51 can drive the driving shaft 52 to rotate; the driving shaft 52 is connected to the positioning device 2, the punching device 3 and the pushing device 4, and then can drive the positioning device 2, the punching device 3 and the pushing device 4 to perform corresponding work, and at the same time can realize the linkage of the positioning device 2, the punching device 3 and the pushing device 4, so as to realize the continuity of production and ensure the production rhythm.

[0066] Reference Figure 1 A cooling device 7 is provided on one side of the workbench 1. The cooling device 7 includes a cooling pool 71. The cooling pool 71 is vertically upward and filled with coolant. Therefore, the cooling pool 71 can cool the metal strip. A material guide roller 72 is horizontally installed in the cooling pool 71. The material guide roller 72 is cylindrical, and its two ends are fixed on the opposite side walls of the cooling pool 71. The material guide roller 72 can rotate circumferentially. The vertical bottom of the material guide roller 72 is in contact with the coolant in the cooling pool 71. Therefore, the material guide roller 72 can press the metal strip into the coolant to cool the metal strip and ensure that the metal strip is covered with the coolant. At the same time, the material guide roller 72 can rotate on its own, which can ensure that the feeding of the metal strip will not be affected.

[0067] Reference Figure 2 and Figure 3The positioning device 2 includes a linkage mechanism 21, which includes a first cam 211 and a pawl 212. The first cam 211 is installed on the driving shaft 52, and the driving shaft 52 can drive the first cam 211 to rotate; one side of the pawl 212 is roller-shaped, and this side is in conflict with the outer peripheral side of the first cam 211, so the first cam 211 can drive the pawl 212 to move; a first elastic element 215 is arranged at the bottom of the pawl 212, which is a spring. The spring is arranged along the movement direction of the pawl 212 and is interconnected with the pawl 212. Therefore, the pawl 212 can be reset after the first cam 211 drives the pawl 212 to move, so that the pawl 212 is always in conflict with the outer peripheral side of the first cam 211, thereby realizing the reciprocating motion of the pawl 212.

[0068] Reference Figure 2 and Figure 3 The linkage mechanism 21 also includes a ratchet 213 and a second cam 214. One side of the pawl 212 abuts against the circumference of the ratchet 213, so that the reciprocating motion of the pawl 212 can drive the ratchet 213 to rotate; the second cam 214 is arranged above the ratchet 213 in the vertical direction, and the ratchet 213 and the second cam 214 are coaxially connected in the vertical direction, so when the ratchet 213 rotates, it can drive the second cam 214 to rotate synchronously.

When the metal strip is placed in the fixed groove 223 along the opening direction of the fixed groove 223, the moving direction of the sliding component 221 is the same as the inclination direction of the snaps obliquely arranged on the metal strip. Therefore, the sliding component 221 can drive the metal strip to move along the inclination direction of the snaps obliquely arranged on the metal strip, and then, under the premise that the position of the blanking device 3 is fixed and the blanking device 3 has only one blanking head, the blanking of the snaps at all positions on the metal strip can still be completed.

[0070] Reference Figure 2 and Figure 3An anti-curling pressure plate 224 is arranged on the fixing component 222. The side of the fixing groove 223 close to the cooling pool 71 is the entrance, and the other side is the exit. The anti-curling pressure plate 224 passes through the top of the fixing groove 223 and is arranged at the exit position of the fixing groove 223. Therefore, it can prevent the metal strip from curling at the exit position and making it impossible to perform punching.

[0071] Reference Figure 2 and Figure 3 A push rod 24 extends outward from the sliding part 221 in the direction of the guide rail 23, and the end of the push rod 24 is roller-shaped.
