Technical Field

[0001] The utility model belongs to the technical field of metal stamping jigs, in particular to a punching jig with automatic flashing. Background Art

[0002] In precision and high-precision stamping products, there are holes of various shapes and sizes. In our usual process of stamping large and small holes, the upper die punch contacts the lower mold cavity and moves downward to separate the waste from the substrate to form a hole on the substrate. The punch is easily affected by the negative pressure of the lower die during the return stroke. When the punch leaves the upper surface of the product, iron wire (chips) are often brought out and it is difficult to avoid. Sometimes, due to customer requirements, the iron wire (chips) need to be removed manually, which seriously affects production efficiency. Utility Model Content

[0044] There are two handles 8 , which are arranged diagonally on the lower clamping plate 3 .

[0045] There are two sensor fixing blocks 9 , and the two sensor fixing blocks 9 are located on both sides of the guide rail.

[0046] Working principle: During the automatic brushing process, when the fixture is in the starting state, the cylinder 5 clamping rod is in a parallel state with the upper clamping plate 1 assembly (i.e., open state). The operator takes 1 PCS of products with each hand and puts them into the positioning cavity composed of the product shape tube position 12 and the upper and lower groove edges. There are 2 PCS of products on each side, a total of 4 PCS of products. Press the control button of the electric control box, and the cylinder 5 clamping rod rotates 90 degrees (i.e., closed state) to press the product downward, and then the upper clamping plate 1 assembly slides to the left along the guide rail to brush the leftmost end a , b, c, d, a total of 10PCS of residual flashing at the orifice. When the sensor on the left senses the left surface of the upper clamping plate, the relay of the electric control box controls the clamping plate 1 assembly to slide to the right along the guide rail to brush the residual flashing of a, b, c, d, a total of 10PCS of orifice. When the sensor on the right senses the right surface of the upper clamping plate, the work is finished. The cylinder 5 clamps the pressure rod and rotates 90 degrees upward (that is, the state is open) to release the product. The operator takes out 1PCS of products with his left and right hands, and 2PCS on the upper and lower sides, a total of 4PCS of products. Complete the entire flashing process to avoid residual iron wire (shavings) at the product orifice. This structure is compact, does not occupy additional space, is easy to use, and effectively saves labor costs.
