Description

Die-cut mould of self-lubricating can realize

Technical Field

The utility model relates to a die-cut mould, specifically say so, relate to a die-cut mould that can realize self-lubricating.

Background

The punching die is generally used for punching and processing metal or alloy plates with specific shapes and holes, and comprises an upper die base, a lower die base, a cutter, a punch, a stripper plate and a lower die block, wherein the cutter and the punch are fixedly connected with the upper die base, the lower die block is fixedly connected with the lower die base, the cutter is provided with a cutting hole which is consistent with the shape of the outer edge of a product to be punched and formed, the stripper plate is matched with the shape of the cutting hole and can move up and down in the cutting hole, the top surface of the lower die block is matched with the bottom surface of the stripper plate, the stripper plate is penetrated out from the bottom of the punch, and the upper die base is connected with a punching driving mechanism. During specific processing, a plate to be punched is clamped between the stripper plate and the lower die block, and the upper die base is driven to move downwards through the punching driving mechanism so as to apply pressure to the cutter and the punch, so that a blank with a prefabricated shape (the shape is consistent with that of a cut hole) can be punched and a hole can be punched on the blank.

In the continuous punching process of the die, the punching heat is high, and the contact between the cutter and the plate is frequent, so that the plate is easily adhered to the cutter to be hardened, and finally the edge of the die is damaged. The traditional solution is that the die is stopped intermittently in the processing process, and the edge circumference of the cutter and the plate are coated with oil and lubricated manually, and the manual lubrication operation has the disadvantages that the lubrication process cannot be effectively controlled, so that the lubricating oil is volatilized in advance in practical application, and the lubrication is insufficient; or excessive lubricating oil is adhered to the punch, so that waste materials are adhered to the punch, the waste materials are not beneficial to normal use of a punching die and are more beneficial to normal use of a high-speed punching die, and if insufficient lubrication occurs in the high-speed running process of the die, a large amount of heat is generated in a short time, so that the working environment of the die is deteriorated, the wear is accelerated, and the service life of the die is influenced; if the phenomenon of adhesion of waste materials occurs, the product or the die can be damaged, and the processing efficiency and the product percent of pass are seriously influenced.

In order to solve the problems of many defects of the artificial lubrication, the application number is as follows: 029202419194 discloses a die-cut mould of self-lubricating in the chinese utility model patent, this patent through set up the batch oil tank and through the oil pump of tube coupling batch oil tank, with the mouth of pipe of the play oil pipe that the export of oil pump is connected is located the top of pressing the flitch to on press and seted up a plurality of oil drip holes on the flitch, and then set up the oil gallery around pressing the flitch down on the lower mould, oil return passage and batch oil tank intercommunication in the oil gallery is located the lower mould. Oil liquid flows onto the plate from an oil dripping hole on the upper pressure plate and then flows onto the circumferential edge of the cutter through the plate so as to continuously lubricate the plate and the circumferential edge of the cutter. The oil flowing down from the cutter further flows to the lower material pressing plate, then drips from the periphery of the lower material pressing plate and converges into the oil return groove, and finally flows back to the oil storage tank through the oil return channel. Although this patent need not to stop the mould and carry out manual oiling operation, because the lubrication mode of this patent is through setting up the oil drip hole on last pressure flitch, makes lubricating oil drip to the panel of waiting to process to the lubrication of realization to panel and the lubrication of the cutter bottom surface that contacts with the panel surface, consequently this kind of lubrication mode has following defect: 1) the working surface at the side part of the cutting knife cannot be lubricated; 2) a lot of lubricating oil is left on the machined workpiece, and cleaning and post-treatment are needed, so that the sewage problem, extra working hours and cost are generated; 3) in order to simultaneously realize the lubrication of the cutter edge, enough lubricating oil must be dripped on the plate, although the plate can be recycled through the arranged oil return groove, the oil return cannot avoid containing scraps in processing, and when the plate and the cutter edge are repeatedly reused, the plate and the cutter edge are easily polluted, and the product percent of pass is influenced.
