Device for synchronously blanking scraps and removing burrs for progressive die

Abstract

The invention discloses a device for synchronously blanking scraps and removing burrs for a progressive die. An insert assembly capable of sliding leftwards and rightwards is arranged at a notch at the final blanking position of the progressive die. The insert assembly comprises a female die sliding block, a sliding block cushion, an up-and-down floating sliding block and an inclined wedge, wherein the female die sliding block can move transversely and longitudinally in a female die plate; the sliding block cushion is embedded in a lower base plate; the up-and-down floating sliding block can slide along the sliding block cushion; the inclined wedge can vertically move; the upper end face of the sliding block cushion and the lower end face of the up-and-down floating sliding block are inclined planes which are in sliding fit; the female die sliding block is provided with a blanking working hole; the upper end of the blanking working hole is provided with a burr step protruding towards the inside of the hole; and the edge of the burr step is provided with a chamfer angle. Due to the adoption of the device, the problem that the scraps and connected materials of the progressive die cannot be removed so that the burrs are finally left is completely solved, the scrap blanking and the burr removal on a blanked workpiece can be completed only by once positioning, the cost of manually removing the burrs or removing the burrs by a single engineering die is saved, and the production efficiency and the product quality are greatly improved.

Description

【Technical field】 [0001] The invention relates to a device for removing laps and burrs in the field of hardware processing, in particular to a device for synchronously punching laps and removing burrs with a continuous die. 【Background technique】 [0002] The continuous die in the existing metal mold usually refers to the linear feeding direction of the punched raw material on the die, which has at least two or more stations, and is completed at different stations in one stroke of the press. Multiple stamping operations. With the development of the hardware manufacturing industry, the requirements for hardware parts are becoming more and more sophisticated, especially for the safety performance of hardware products. However, in the stamping process of the metal mold, sharp burrs often appear on the truncated surface after punching, which makes it inevitable that the operator will come into contact with the sharp burrs when the hardware parts are assembled into a product, wh...

Problems solved by technology

However, in the stamping process of the metal mold, sharp burrs often appear on the truncated surface after punching, which makes it inevitable that the operator will come into contact with the sharp burrs when the hardware parts are assembled into a product, which is very easy to cause damage to the operation Personnel injury, safety accidents, in addition, some hardware parts are to be assembled in electronic appliances, the burrs on the hardware parts may fall on the electronic components, greatly increasing the possibility of circuit failure, so now product designers It is required that the hardware parts should not have burrs

Although the existing metal continuous mold can easily remove the burr, but it is very difficult to remove the burr at the edge joint of the connected product, because the edge is always connected to the workpiece until the final process before punching, and generally cannot be done in this mold after punching. Deburring in the next process usually requires additional processing to remove the burrs, or additional stamping to remove the burrs, which increases the manufacturing cost

Moreover, the process of adding stamping to remove burrs is a single stamping, which must be manually operated to pick and place the workpiece, which is inefficient and has no guarantee of safety.
