Description

Technical Field

[0001] This utility model relates to the field of circular tube stamping technology, and in particular to a circular tube stamping die. Background Technology

[0002] Round tubes are widely used in automobiles, construction, home appliances and other fields. Their manufacturing process has an important impact on product quality and production efficiency. Traditional stamping dies have problems such as low efficiency and complicated operation in terms of die replacement and waste disposal, which makes it difficult to meet the needs of modern industry for efficient and environmentally friendly production. Therefore, a stamping die for round tubes is designed.

[0003] The replacement of stamping dies for round tube fittings usually requires machine downtime, which is time-consuming. At the same time, the collection of cutting waste relies mainly on manual labor or simple mechanical devices, which has problems such as low efficiency and great safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a circular tube stamping die, which allows the lower plate that fits with it to be separated, so as to achieve quick disassembly and replacement of the die. The lower die interior and the lower end cutting port fit together so that the waste material falls from the cutting port for easy collection.

[0005] To achieve the above objectives, a circular tube stamping die is provided, comprising an upper plate, a fixed ring fixedly connected inside the upper plate, a hydraulic press fixedly connected inside the fixed ring, a fixed plate fixedly connected to the output end of the hydraulic press, a movable column fixedly connected to the lower end of the fixed plate, an upper die fixedly connected to the lower end of the movable column, a support column fixedly connected below the upper plate, a lower plate fixedly connected to the lower end of the support column, a disassembly plate provided inside the lower plate, a lower die fixedly connected to the upper end of the disassembly plate, a movable plate movably fitted inside the lower die, four grooves provided at the four corners of the disassembly plate, movable rods provided inside the grooves of the disassembly plate, limit caps fixedly connected to the upper ends of the movable rods, a No. 1 spring fixedly installed outside the movable rods, the disassembly plate communicating with the lower plate, a limit rod fixedly connected between the disassembly plate and the lower plate, and a limit plate fixedly connected outside the limit rod.

[0006] According to the circular tube stamping die, the support columns are evenly and symmetrically distributed at the four corners of the upper plate.

[0007] According to the circular tube stamping die, a circular cutter and an arc-shaped cutter are fixedly connected in the middle of the fixed plate.

[0008] According to the circular tube stamping die, the lower die has a slot in the middle and a fixed shaft is fixedly connected to it. The fixed shaft is fixedly connected to a movable plate. A second spring is provided at the lower end of one side of the movable plate and is connected to the lower die.

[0009] According to the circular tube stamping die, a No. 1 spring is provided between the disassembly plate and the limiting plate.

[0010] According to the circular tube stamping die, the limiting rod and the limiting plate are fixedly connected by a spring.

[0011] According to the circular tube stamping die, the movable columns are evenly and symmetrically distributed at the four corners of the fixed plate.

[0012] According to the aforementioned circular tube stamping die, the upper die and the lower die are provided with a circular cut and an arc cut inside, and the circular cut and the arc cut are connected to the lower cutting port.

[0013] According to the circular tube stamping die, the lower plate has a placement groove inside, and the disassembly plate is installed inside the placement groove of the lower plate.

[0014] Beneficial effects:

[0015] 1. The unloading plate has four grooves at its four corners, and a movable rod is installed inside the groove. The upper end of the movable rod is fixedly connected to the limiting cover, and a No. 1 spring is fixedly installed on the outside of the movable rod. The unloading plate and the lower plate are connected through the limiting rod. When the limiting cover is opened and closed, a lever movement will occur. When the limiting cover is opened upward, the movable rod will be stretched upward. When the movable rod is stretched upward, one of the limiting rods will move laterally against the bottom slope of the movable rod, so that the lower plate that it is fitted with will be separated, thus achieving quick disassembly and replacement of the mold.

[0016] 2. The lower mold has a slot in the middle and a fixed shaft is fixedly connected to the movable plate. A second spring is set at the lower end of one side of the movable plate and is connected to the lower mold. When the upper mold presses down, it provides downward pressure to the higher side of the movable plate, making the movable plate level. When the curved cutter cuts, the curved waste falls onto the movable plate. When the curved cutter rises, the downward pressure on one side of the movable plate disappears, and the second spring at the lower end of the movable plate supports the movable plate, making it perform a lever movement. The movable plate tilts, and the curved waste falls out of the movable plate for easy collection later. The interior of the lower mold and the lower cutting port fit together so that the waste falls from the cutting port for easy collection.
