An automatic loading mechanism is provided on the left side of the worktable, and an automatic unloading mechanism is provided on the front side of the worktable.

[0024] The automatic feeding mechanism comprises a non-powered roller conveyor 7 for placing the raw material 27 to be punched, and support frames 8 symmetrically installed on the front and back of the non-powered roller conveyor frame, a rotating roller shaft 9 rotatably arranged between the top of the two support frames, a transmission swing rod 10 and a feeding rod 11 fixed at a 90° angle on the right side and the lower side of the rotating roller shaft, the right end of the transmission swing rod being rotatably connected with the punch head, the up-down movement of the punch head can drive the rotating roller shaft to rotate, the lower end of the feeding rod is provided with a friction rubber pad 12, the friction rubber pad is made of rubber material, the lower surface thereof is inclined and arc-shaped with the left side being lower than the right side, and the lower surface is further provided with knurling for increasing friction, the friction between the friction rubber pad and the upper surface of the raw material to be punched can drive the raw material to be punched to move to the right for feeding, in order to ensure the strength of the friction propulsion, even allowing the friction rubber pad to be deformed to a certain extent.

[0025] The automatic feeding mechanism comprises a non-powered roller conveyor 7 for placing the raw material 27 to be punched, and support frames 8 symmetrically installed on the front and back of the non-powered roller conveyor frame, a rotating roller shaft 9 rotatably arranged between the top of the two support frames, a transmission swing rod 10 and a feeding rod 11 fixed at a 90° angle on the right side and the lower side of the rotating roller shaft, the right end of the transmission swing rod being rotatably connected with the punch head, the up-down movement of the punch head can drive the rotating roller shaft to rotate, the lower end of the feeding rod is provided with a friction rubber pad 12, the friction rubber pad is made of rubber material, the lower surface thereof is inclined and arc-shaped with the left side being lower than the right side, and the lower surface is further provided with knurling for increasing friction, the friction between the friction rubber pad and the upper surface of the raw material to be punched can drive the raw material to be punched to move to the right for feeding, in order to ensure the strength of the friction propulsion, even allowing the friction rubber pad to be deformed to a certain extent.

[0026] The shear telescopic arm comprises two driving arms 13 cross-connected in an "X" shape and two telescopic arms 14 in a parallelogram shape and connected at the front ends of the two driving arms, wherein the driving end of one driving arm is hingedly connected with the right side of the front side wall of the workbench through a fixed hinge seat 15, and the driving end of the other driving arm is hingedly connected with the front part of the right side wall of the punch head through a follow-up hinge seat 16; the front end of the two telescopic arms is further connected with a telescopic slide rod 17, the rear end of the telescopic slide rod is riveted with a receiving disc 18, and the middle part of the telescopic slide rod is provided with a guide long hole 19 in the front-rear direction, and the inner end of the pin shaft 20 of the two driving arms is slidably arranged in the guide long hole for guiding and limiting the sliding of the telescopic slide rod in the front-rear direction.

[0027] The workbench of the punch machine is provided with a finished product box 21 in front for receiving the formed workpieces 25 after punching, and is provided with a waste box 22 on the right side for receiving the leftover materials 26 after punching, which will be automatically pushed out and fall down from the right side of the workbench into the waste box with the automatic feeding of the raw material to be punched.

[0028] When the punch head rises, the shear telescopic arm contracts, drives the telescopic slide rod to slide backward, drives the receiving disc to move backward and be inserted below the upper punch die to receive the formed workpiece falling from the upper punch die.

[0029] When the punch head is pressed down, the telescopic arm front end of the scissor telescopic arm will be synchronously extended forward, and the telescopic slide rod will slide forward, thereby carrying the material receiving disc and the formed workpiece received thereby to move forward, to withdraw and gradually move away from directly below the upper punch, and since the material receiving disc is a slide-like structure with a front low and rear high configuration, when the material receiving disc moves forward to above the finished product box, the formed workpiece will automatically slide into the finished product box due to inertia and gravity.

[0030] The rear end left side of the telescopic slide rod is fixedly connected with a material receiving disc, and the material receiving disc is a slide-like structure with a front low and rear high configuration, and the material receiving disc can follow the telescopic slide rod to extend into and out of the upper punch and the lower punch, thereby automatically receiving the punched formed workpiece falling from the upper punch.

[0031] The right end of the transmission swing rod is hingedly connected with a pin connection seat 23, which is fixedly connected with the punch head. With the telescopic movement of the punch head up and down, the right end of the transmission swing rod swings up and down, thereby driving the feeding lever to swing left and right in an arc through the rotating roller shaft; when the punch head is pressed down, the feeding lever drives the friction rubber pad at the lower end thereof to tilt up leftward, away from the upper surface of the material to be punched, so that the material to be punched is not pushed at this time; when the punch head is lifted up, the feeding lever drives the friction rubber pad to swing rightward and downward, and gradually abuts against the upper surface of the material to be punched, and then the friction rubber pad continues to swing rightward and downward, thereby pushing the material to be punched to move a certain distance rightward, thereby completing automatic feeding. However, when the punch head is pressed down and the friction rubber pad swings upward again, since the left side of the lower surface of the friction rubber pad is low and the right side is high, the friction rubber pad will as quickly as possible get away from the upper surface of the material to be punched, so as to avoid the phenomenon of the material to be punched being pushed backward.

[0032] The upper punch is provided with a material removing spring 24 in the middle, for removing the formed workpiece remaining in the upper punch after being punched. When the upper punch punches the workpiece downward, the material removing spring will be compressed into the middle cavity of the upper punch, and when the upper punch is lifted up after being punched, the material removing spring will automatically rebound to remove the formed workpiece stuck in the middle cavity of the upper punch. At the same time, the scissor telescopic arm drives the material receiving disc to extend into directly below the upper punch to receive the formed workpiece falling from the upper punch, and then with the upper punch being pressed down again, the scissor telescopic arm moves forward to gradually withdraw away from the upper punch, and the material receiving disc carries the formed workpiece to above the finished product box and drops the formed workpiece into the finished product box, thereby completing automatic feeding.

[0033] The technical scheme of the utility model is not limited by the above specific embodiments, and many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments, and any technical modification made within the spirit and principle of the utility model falls within the protection scope of the utility model.
