Description

Technical Field

[0001] The utility model relates to the technical field of processing lower connecting plate precision forgings, in particular to a lower connecting plate precision forging flash cutting device with edge extension positioning. Background Art

[0002] Motorcycle lower connecting plate precision forging refers to the connecting plate at the bottom of the motorcycle, which is made by precision forging technology. The lower connecting plate is located at the bottom of the motorcycle, connecting the motorcycle frame and the drive system, playing the role of supporting and transmitting power.

[0003] The lower connecting plate is usually made of high-strength alloy steel and processed by precision forging technology. Compared with traditional castings, precision forgings have higher material density and tensile strength, and can provide better structural strength and durability.

[0004] In the production process of precision forgings, the material usually produces uneven edges such as edge extension and burrs after forging. These irregular edges may affect the quality and processing accuracy of the precision forgings, so they need to be cut off and trimmed.

[0005] The existing flash cutting device is not convenient for accurate feeding and positioning of precision forgings, and cannot stably and accurately position the lower connecting plate precision forgings, which affects the accuracy and stability of equipment processing.

[0006] Therefore, we propose a flash cutting device for lower connecting plate precision forgings with edge positioning to solve the problems in the above background. Utility Model Content

[0007] The utility model aims to provide a flash cutting device for a lower connecting plate precision forging with edge positioning, so as to solve the problems raised in the above-mentioned background technology.

[0008] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0009] A flash cutting device for a lower connecting plate precision forging with edge positioning includes a positioning component and a cutting component, wherein the positioning component includes a positioning column, wherein the positioning column is internally sleeved with the shock-absorbing mounting hole of the lower connecting plate, wherein the outer diameter of the positioning column is matched with the inner diameter of the lower connecting plate, a support platform is provided at the bottom of the positioning column, an electric lifting column is installed at the bottom of the support platform, a pressure plate is provided above the electric lifting column, and the upper part of the pressure plate is fixedly connected to a spring.

[0010] Preferably, the cutting assembly comprises a ring cutter, the cross-sectional shape of which is adapted to the outer edge of the lower connecting plate precision forging.

[0011] Preferably, the outer side of the lower end of the circular cutting knife is sharpened, and the circular cutting knife is arranged above the positioning column.

[0012] Preferably, a cylinder is installed on the upper end of the circular cutting knife, and a support frame is fixedly connected to the upper end of the cylinder.

[0013] Preferably, the pressure plate is installed on the inner side of the circular cutting knife, and the spring is installed inside the lower end of the circular cutting knife.

[0014] Preferably, the pressure plate is fixedly connected to a positioning slide rod, and the upper end of the slide rod is slidably connected to the inside of the circular cutting knife.

[0015] Preferably, the support platform is matched with the bottom surface of the lower connecting plate precision forging, and a debris collection trough is provided below the support platform.

[0016] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0017] First, the utility model is connected to the outside of the positioning column through the shock-absorbing mounting hole of the lower connecting plate, and the positioning column keeps the lower connecting plate stable in the horizontal direction. Then the electric lifting column pushes the support platform up, and the support platform drives the positioning column and the lower connecting plate to move upward. The upper connecting plate of the lower connecting plate fits the bottom surface of the pressure plate, and the elastic force of the spring is used to clamp the pressure plate and the upper part of the lower connecting plate, so that the lower connecting plate is kept stable in the longitudinal direction, thereby realizing the edge positioning of the lower connecting plate, and then the circular cutting knife is pushed downward by the cylinder to perform an overall one-time removal of the flash extending from the edge of the lower connecting plate. As the circular cutting knife pushes downward, it drives the spring to compress, so that the pressure plate clamps the lower connecting plate more stably, so that the edge removal of the lower connecting plate is fast, stable and accurate.

[0018] Secondly, the utility model matches the cross-sectional shape of the circular cutter with the outer edge of the precision forging of the lower connecting plate, and presses down the circular cutter to quickly cut the edge of the lower connecting plate at one time. The outer side of the lower end of the circular cutter is sharpened to make the cut flash debris fall to the outside, and the cylinder is fixedly supported by the support frame so that it can work to push the circular cutter to cut stably. The positioning slide bar slides up and down inside the circular cutter to make the pressure plate rise and fall longitudinally, which is beneficial to positioning and locking the lower connecting plate. At the same time, it cooperates with the positioning column for horizontal positioning to prevent it from sliding, thereby achieving stable and accurate edge cutting. The cut flash debris falls from the outside of the support platform into the debris collection tank for convenient recycling. BRIEF DESCRIPTION OF THE DRAWINGS
