detailed description

In order to describe the utility model more clearly, the utility model will be further described below in conjunction with the accompanying drawings.

A simple punching die for a beam tube, which includes a pressure source 1, a die and a workbench 13, and is characterized in that the die includes a handle assembly 2, a punch assembly 3, a punch guiding die positioning block 4 and a die 5. The pressure source 1 is the slider of the stamping equipment. There is a mold handle fixing hole at the lower end of the slider. The mold handle assembly 2 is fixedly connected with the pressure source 1 through this fixing hole; the lower surface of the mold handle assembly 2 is provided with two The vertical plate passing through the shaft hole, the vertical plate protruding from the upper surface of the punch assembly 3 is sandwiched between the two vertical plates of the mold handle assembly 2 and is slidably connected by a pin shaft;

The punch guide die positioning block 4 is provided with a guide hole that the punch on the punch assembly 3 can be inserted into. Each side is provided with a groove, and the two grooves are respectively fixedly connected with the workbench 13 through the pressing plate;

The front side of the convex mold guiding concave mold fixing block 4 is vertically fixedly connected with the positioning pallet 8, and several positioning plates 9 are installed on the pallet seat of the positioning pallet 8, and each positioning plate 9 is provided with a through hole for positioning, and a workpiece clip 7 is the fixing assembly of the positioning sleeve and the positioning plate. The positioning sleeve of the workpiece clip 7 is provided with a clamping bolt for clamping the workpiece 6. The positioning plate of the workpiece clip 7 is provided with a through hole for positioning. The positioning of the through hole and the workpiece clamp 7 is connected with the positioning pin through the through hole, and the positioning sleeve socket of the workpiece clamp 7 is horizontally corresponding to the positioning hole of the punch guiding die positioning block 4;

The rear side of the convex mold guiding concave mold fixing block 4 is vertically fixedly connected with the die connecting plate supporting plate 11. The die connecting plate supporting plate 11 is provided with a tail support plate 12, and the die 5 is fixed on the tail through the die connecting plate 10 On the backing plate 12 to fix the position of the die 5.
