Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and specifically relates to a stamping die. Background Technology

[0002] Stamping dies are important process equipment used in industrial production for stamping processing. They are mainly used for the separation, forming, bending, stretching and other processing of metal or non-metal sheets. In the stamping process of metal sheets, the sheet is usually placed on the die and the punch is driven by the stamping machine to perform the processing. The performance of stamping dies directly affects production efficiency and product quality.

[0003] Traditional stamping dies typically involve the sheet metal directly contacting the die surface. During the stamping process, the high frictional resistance can easily lead to scratches and uneven deformation on the sheet metal surface, and even affect stamping accuracy. In high-intensity continuous stamping operations, the repeated friction between the die and the sheet metal will accelerate die wear, reduce service life, and increase maintenance costs. To solve the above problems, we provide a stamping die. Utility Model Content

[0004] The purpose of this utility model is to provide a stamping die to solve the problems mentioned in the background art. Traditional stamping dies usually have the sheet metal in direct contact with the die surface. During the stamping process, due to the large frictional resistance, the sheet metal surface is easily scratched, deformed unevenly, and even the stamping accuracy is affected. In high-intensity continuous stamping operations, the repeated friction between the die and the sheet metal will accelerate the wear of the die, reduce its service life, and increase maintenance costs.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stamping die, including a base plate, wherein two die mechanisms are provided on the top of the base plate;

[0006] The mold mechanism includes a module, an end plate on the front of the module, a rotating roller rotatably connected between the module and the end plate, an oil tank inside the module, a fixing block on the top of the module, an oiling plate fixedly sleeved inside the fixing block, and one end of the oiling plate abutting against the rotating roller.

[0007] Preferably, the bottom of the module is bolted to the base plate, the top of the module has a groove, a mounting plate is provided on one side of the module, a soft scraper is bolted to one side of the mounting plate, a guide groove is provided on the top of the soft scraper, the top of the soft scraper abuts against the rotating roller, and a filter hole is provided at the bottom of the groove.

[0008] Preferably, the contact surfaces of the module and the end plate are provided with mounting grooves, and a sealing strip is placed inside the mounting grooves. A first bolt is fitted inside the end plate, and one end of the first bolt is threaded to the module. Two second bolts are fitted inside the mounting plate, and one end of the two second bolts is threaded to the module and the end plate, respectively. Two third bolts are fitted inside the fixing block, and one end of the two third bolts is threaded to the module and the end plate, respectively.

[0009] Preferably, the bottom plate has a top plate at its top, a punch is bolted to the bottom of the top plate, and positioning rods are bolted to both sides of the bottom of the top plate. A pressure plate is slidably sleeved on the surface of the positioning rod. A positioning sleeve adapted to the positioning rod is bolted to the top of the bottom plate. The interior of the positioning sleeve is slidably inserted into the positioning rod. A spring is sleeved on the surface of the positioning rod. The top of the spring is bolted to the top plate, and the bottom of the spring is bolted to the pressure plate. A through hole adapted to the punch is opened inside the pressure plate. Bolt grooves are opened on both sides of the bottom plate and the top plate.

[0010] This utility model has the following beneficial effects:

[0011] This device places the sheet metal on top of two mold mechanisms and is stamped by a punch driven by a press. During the stamping deformation process, the sheet metal drives the rotating rollers to rotate synchronously, achieving smoothness and continuity in the stamping process and significantly improving processing efficiency. The collaborative design of the rotating rollers and the oiling plate constitutes a self-lubricating system. The oiling plate continuously absorbs lubricating oil from the oil tank and automatically and evenly applies it to its surface when the rotating rollers rotate. This not only effectively reduces the coefficient of friction between the sheet metal and the rotating rollers and avoids scratches on the sheet metal surface, but also greatly extends the service life of the rotating rollers and the molds as a whole, while reducing the frequency of manual oiling maintenance. It is especially suitable for high-intensity continuous stamping operations. Attached Figure Description
