When the punch arm 105 moves downward, the clamp 203 does not rotate, and the metal plate is fixed to complete punching. The automatic continuous punching action of the metal plate can be realized by repeating the actions. Greatly improving the working efficiency and reducing the production cost.

Example 3

Referring to fig. 1 to 10, there is shown a third embodiment of the present invention, which is based on the first two embodiments.

Specifically, the intermittent motion member 201 includes a connecting rod 201a disposed at the other end of the slider 104d, an incomplete gear 201b disposed at the bottom of the connecting rod 201a, and a first gear 201c disposed at one side of the incomplete gear 201b, the number of teeth of the incomplete gear 201b is less than half of the number of teeth of the complete gear of the same specification, and two ends of the connecting rod 201a are rotatably connected to the slider 104d and one end of the incomplete gear 201b having teeth through pin shafts, respectively. When the slider 104d is at the highest position, the toothed end of the incomplete gear 201b is also at the highest position, and when the slider 104d moves downwards, the incomplete gear 201b rotates clockwise according to the front view in the figure, and at the moment, the incomplete gear is not meshed with the first gear 201c, and the first gear 201c does not rotate. When the slider 104d is raised from the lowest position, the toothed end of the incomplete gear 201b is also rotated clockwise from the lowest position in the front view, and gradually starts to mesh with the first gear 201c, and the first gear 201c starts to rotate. Repeating the above-mentioned action can realize that the slider 104d reciprocates up and down to drive the first gear 201c to rotate intermittently. The reason why the number of teeth of the incomplete gear 201b is less than half of the number of teeth of a complete gear of the same specification is to prevent the first gear 201c from rotating to cause a motion conflict when the punching die at the bottom of the punching arm 105 is not yet completely withdrawn. The specific tooth number can be set according to the actual conditions such as the thickness of the metal plate, the requirement of the punching gap and the like.

Preferably, the intermittent motion member 201 further comprises a limit spring 201d disposed on the side surface of the bottom of the connecting rod 201a, the limit spring 201d is an extension spring, and the limit spring 201d is disposed to prevent the connecting rod 201a from moving in a specified required direction, so as to avoid a wrong moving direction.

Preferably, the rotating member 202 includes a first bevel gear 202a coaxially rotating with the first gear 201c, a second bevel gear 202b coaxially rotating with the first bevel gear 202a, a third gear 202c coaxially rotating with the second bevel gear 202b, and a fourth gear 202d coaxially rotating with the third gear 202c, wherein the number of the fourth gears 202d is set to six.

Further, it is characterized in that: the clamping member 203 further comprises a guide clamp plate 203b arranged on the top of the bracket 106, and the guide clamp plate 203b can adjust the clamping tightness along the moving groove thereof according to actual conditions.

In use, as sheet metal is transported from the conveyor to the station above the carriage 106, it is held in place by the clamp 203 and the desired punch die is mounted on the underside of the punch arm 105. The servomotor 102 is actuated to rotate the rotary disk 104a, and when the pulley at the bottom of the drive rod 104b rotates to the maximum radius of the spiral groove 104a-1, the drive rod 104b is pushed to the highest position, and when the pulley rotates to the minimum radius, the drive rod 104b also falls to the lowest position. The continuous rotation of the rotary plate 104a repeats the above-described operation to reciprocate the drive rod 104b up and down. The inside of the inside spout 104c of support column 103 still is provided with buffer spring 104e, avoids slider 104d to cause the impact to the device at the in-process of whereabouts, plays certain cushioning effect. When the punching arm 105, that is, the slider 104d, is at the highest position, the toothed end of the incomplete gear 201b is also at the highest position through the connection of the link 201a, and when the punching arm 105 moves downwards to start punching, the incomplete gear 201b rotates clockwise in the front view of the drawing, and at this time, the incomplete gear 201b is not meshed with the first gear 201c, and the first gear 201c does not rotate. When the punching die at the bottom of the punching arm 105 is separated from the metal plate and rises from the lowest position, the toothed end of the incomplete gear 201b also rotates clockwise from the lowest position according to the front view of the figure and gradually engages with the first gear 201c, the first gear 201c starts to rotate, the coaxial first bevel gear 202a drives the second bevel gear 202b to rotate, and the third gear 202c also starts to rotate and drives the fourth gear 202d to rotate. The driving wheels 203a, which are coaxially connected to the four fourth gears 202d, respectively, start to rotate and drive the metal plate to move forward a small distance. Wherein the guide clamp 203b can adjust the clamping tightness along the moving groove thereof according to actual conditions. The automatic continuous punching action of the metal plate can be realized by repeating the actions. Greatly improving the working efficiency and reducing the production cost.
