Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to the attached drawings 1-2, a workpiece fixing mechanism for a punch press comprises a workbench 1 and is characterized in that symmetrical clamping units are arranged on the workbench 1, a die 2 is arranged between the symmetrical clamping units, the clamping units comprise a driving motor 3, the driving motor 3 is fixedly arranged below the workbench 1, a first gear 4 is fixedly arranged at the output end of the driving motor 3, the first gear 4 is in meshed connection with a second gear 5, the second gear 5 is connected with a rotating shaft 6, the rotating shaft 6 penetrates through the workbench 1 to the upper part and is rotatably connected with the workbench 1, a transverse through hole 7 is arranged on the rotating shaft 6, a pressing rod 8 is inserted into the transverse through hole 7, a longitudinal through hole 9 is arranged on the rotating shaft 6 above the transverse through hole 7, and a fastening screw 10 is connected with the inner thread of the longitudinal through hole 9, the tail end of the fastening screw 10 is connected with the pressure lever 8 in an abutting mode.

Further, the first gear 4 and the second gear 5 are externally provided with a protective cover 11 to prevent scraps from entering the interior and affecting the working efficiency.

Further, a rubber pad 12 is bonded below the pressure lever 8 to prevent the surface of the stamping plate from being polished.

Further, the pressure rod 8 is provided with a graduated scale, so that the position can be conveniently adjusted.

Further, a controller is arranged and electrically connected with the driving motor 3.

Firstly, a workbench 1 is arranged right below a lower stamping die, the distance between two pressing rods 8 is adjusted according to the size of a stainless steel sheet, the pressing rods 8 move leftwards and rightwards in a transverse through hole 7 and are fixed through fastening bolts, the stainless steel sheet is placed on the die 2, a controller is operated, a driving motor 3 rotates to drive a gear I4, the gear I4 drives a gear II 5, a rotating shaft 6 rotates to drive the pressing rods 8 to rotate to the upper side of the stainless steel sheet and press the stainless steel sheet, the two pressing rods 8 are symmetrical, namely, both sides of the stainless steel are fixed, stamping can be carried out, after stamping is finished, waste materials are under the pressing rods 8 and cannot splash to the outside, manual treatment is needed, and the pressing rods 8 rotate back and are taken down.

It is to be understood that the foregoing examples merely represent preferred embodiments of the present invention, and that the description thereof is more specific and detailed, but not intended to limit the scope of the invention; it should be noted that, for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention; therefore, all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
