[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when punching holes in a steel strip, the steel strip is placed on the top surface of a processing table, and the punching portion of the steel strip is located below a punching frame. At this time, the driving motor drives the driving disc to rotate, and the driving disc drives the transmission disc to rotate through a belt. The rotation of the transmission disc drives the transmission rod to rotate the transmission gear, and the transmission gear drives the rotating gear to rotate, so that the rotating gear can drive two cams to rotate. The punching frame is driven by two pressure springs to keep the set pulley in contact with the cam. When the raised end of the cam contacts the pulley, it drives the punching frame to move toward the steel strip below, thereby punching holes on the surface of the steel strip.

[0013] In the present invention, when the punching frame moves and presses toward the direction of the processing table under the drive of the cam, the fixed rack on the outer wall of the punching frame will move downward synchronously, and at this time the fixed rack will drive the first limiting gear to rotate, and the rotation of the first limiting gear drives the first unidirectional shaft to rotate, and the first unidirectional shaft causes the second limiting gear to rotate, so that the second limiting gear can drive the transmission rack to move, and then driven by the transmission rack, the transmission frame moves toward the top of the supporting frame until the punching frame punches the steel strip, and the wedge block on the transmission frame is clamped into the clamping groove on the retaining frame, and the transmission frame is limited by the wedge block, so that the transmission frame is in a force storage state under the action of the tension spring, thereby facilitating the subsequent further processing of the steel strip.

[0014] In the present invention, when the punching frame is pressed down to punch the steel strip on the processing table, the transmission frame will move up while the punching frame is pressed down. The upward movement of the transmission frame will drive the moving rod to slide in the inner wall of the rotating column. At this time, the clamping rod arranged on the moving rod will contact the arc groove on the inner wall of the rotating column, and then the rotating column will be deflected toward the direction of the steel strip under the restriction of the arc groove. At this time, the positioning frame arranged on the rotating column will limit the upper end surface of the steel strip, so that the steel strip can be stably processed during the punching operation.

[0015] In the present invention, after the punching frame punches holes on the surface of the steel belt, the concave surface of the cam gradually contacts the pulley, which drives the punching frame to move and reset on the carrier frame. At this time, when the punching frame is reset, the fixed rack drives the first limit gear to rotate, but the first one-way shaft will not rotate under the restriction of the first one-way shaft. After the punching frame is reset, the fixed rack on the punching frame will contact the inclined end of the resistance frame, so that the resistance frame moves toward the direction of the wedge block. The wedge block is separated from the clamping groove under the contact of the resistance frame, and the transmission frame is quickly reset under the drive of the tension spring. The reset transmission frame drives the driving tooth plate to rotate the driving gear, and the driving gear drives the second one-way shaft The rotation causes the eccentric frame to rotate, and the eccentric frame drives the pushing frame to move back and forth continuously. The pushing frame drives the connecting rod to make the moving frame slide back and forth in the placement cavity, and the sliding of the moving frame drives the clamping roller to move. The steel strip is located between the two clamping rollers. Then, when the moving frame moves toward the direction of the punching frame, the clamping roller drives the clamped steel strip to move toward the punching frame through the end face of the clamping roller under the restriction of the third unidirectional axis. When the moving frame is reset, the clamping roller slides on the processing table under the influence of the third unidirectional axis, thereby realizing the continuous movement of the steel strip, and the remaining parts of the steel strip that need to be punched can be moved to the bottom of the lower pressing frame to realize the continuous punching operation of the steel strip.

[0016] In the present invention, the operator can move the adjustment frame in the limit groove on the limit clamping plate. Since the limit groove is arranged in an arc shape, the moving distance of the pushing frame and the connecting rod can be changed when the adjustment frame is moved. Then, when the pushing frame is moved driven by the eccentric frame, the reciprocating distance of the moving frame can be adjusted to realize the punching operation of the steel strip with different equal spacings.

At this time, the driving motor 21 drives the driving disc 22 to rotate, and the driving disc 22 drives the transmission disc 25 to rotate through the belt 26. The rotation of the transmission disc 25 drives the transmission rod 23 to rotate the transmission gear 24, and the transmission gear 24 drives the rotating gear 28 to rotate, so that the rotating gear 28 can drive the two cams 29 to rotate. The punching frame 210 is driven by two pressure springs 212 to make the set pulley 213 always contact with the cam 29. When the raised end of the cam 29 contacts the pulley 213, it will drive the punching frame 210 to move toward the steel strip below, and then punch holes on the surface of the steel strip. When the punching frame 210 is driven by the cam 29 to move and press in the direction of the processing table 1, the fixed rack 31 on the outer wall of the punching frame 210 will move downward synchronously.

The upward movement of the driving frame 37 will drive the moving rod 53 to slide in the inner wall of the rotating column 51. At this time, the clamping rod 54 provided on the moving rod 53 will contact the arc groove 52 on the inner wall of the rotating column 51, and then the rotating column 51 will deflect toward the direction of the steel strip under the restriction of the arc groove 52. At this time, the positioning frame 55 provided on the rotating column 51 will limit the upper end surface of the steel strip, so that the steel strip can be stably processed during the punching operation; After the punching frame 210 punches the surface of the steel belt, the concave surface of the cam 29 gradually contacts the pulley 213, which will drive the punching frame 210 to move and reset on the carrier 11. At this time, when the punching frame 210 is reset, the fixed rack 31 will drive the first limit gear 34 to rotate, but under the restriction of the first one-way shaft 33, the first one-way shaft 33 will not rotate. After the punching frame 210 is reset, the fixed rack 31 on the punching frame 210 will contact the inclined end of the contact frame 43, so that the contact frame 43 moves toward the direction of the wedge block 41. The wedge block 41 is separated from the clamping groove 42 under the contact of the contact frame 43, and the transmission frame 37 is quickly reset under the drive of the tension spring 38.
