Description

Technical Field

[0002] A stamping machine is a device that applies pressure to plastically deform a material to achieve the desired shape and precision. Its design principle is to convert circular motion into linear motion. Usually, the main motor drives the flywheel, which drives the gears, crankshaft (or eccentric gear), connecting rod, etc. through the clutch to achieve the linear motion of the slider.

[0003] After checking the announcement number: CN204294811U, a stamping machine tool is disclosed. This technology discloses "including a frame, a horizontal workbench installed on the frame, a lower mold placed on the workbench, an upper mold sliding up and down along the frame above the lower mold, and a transmission device driving the upper mold, the lower mold is provided with a piston cavity from the top to the bottom, and a piston that is slidably matched with it and hydraulically sealed is provided in the piston cavity. A piston rod that is integral with it and extends out of the piston cavity is provided on one side above the piston, and an end cover that is sleeved on the outside of the piston rod and hydraulically sealed with it is provided on the top of the piston cavity. A rodless cavity channel and a rod cavity channel that are connected to the piston cavity are respectively provided on both sides of the corresponding piston on the lower mold, and a support plate that can lift up the stamped part is connected to the top of the piston rod. The technical scheme has the function of injecting hydraulic oil into the rodless cavity channel to lift up the piston, the piston rod and the support plate, so that the forming plate that has not separated from the raw material plate is subjected to an upward external force and is separated from the raw material plate. At the same time, since the piston and the piston rod are located in the piston cavity of the lower mold, the height space is saved, and the equipment is more compact.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the existing stamping machine tools are not convenient for positioning and supporting the workpiece to be stamped. Usually, the fixing effect of the workpiece before stamping is limited, so the positioning may not be accurate enough, which will affect the quality of stamping, and most stamping structures and positioning structures are not easy to replace. Therefore, the types of stamping processing that can be performed are relatively limited, and the range of stamping is not wide. Therefore, a stamping machine tool with efficient positioning is needed to solve the above problems. Utility Model Content

Through the stability of the stamping process, a connecting plate 17 is welded on the output end of the cylinder 13, and the connecting plate 17 is connected to the lifting plate 14 through six bolts. The connecting plate 17 makes it convenient to connect the output end of the cylinder 13 with the lifting plate 14, and the connection is relatively firm, which is convenient for maintenance and repair. A stamping plate 15 is provided at the lower end of the lifting plate 14, and a stamping part 16 is welded on one side of the lower end of the stamping plate 15. Two movable plates 34 are provided at the upper end, and the upper ends of the two movable plates 34 are jointly provided with a support plate 2, three connecting rods 21 are welded at the upper end of the support plate 2, four support rods 22 are welded at the upper end of the connecting rod 21, and four limit members 23 are welded at the upper end of the support plate 2. The bottom plate 1 serves as a supporting structure, and the cylinder 13 on the upper plate 12 is started to make the lifting plate 14 move downward on the pillar 11, and the stamping process is performed by the stamping member 16 at the lower end of the stamping plate 15. The workpiece to be stamped is placed on the support plates 2 on the two movable plates 34, and the workpiece is supported by the support rod 22 on the connecting rod 21, and the workpiece is positioned by the four limit members 23.

The stamping plate 15 is installed by the bolts on the connecting blocks 18. Different stamping plates 15 are provided with stamping parts 16 of different shapes and sizes. This easy-to-replace stamping structure can complete most stamping processes.

[0035] The implementation principle of the embodiment of the present application is: the base plate 1 serves as a supporting structure, and the cylinder 13 on the upper plate 12 is started to make the lifting plate 14 move downward on the pillar 11, and the stamping part 16 at the lower end of the stamping plate 15 is used for stamping processing, and the workpiece to be stamped is placed on the support plate 2 on the two movable plates 34, and the workpiece is supported by the support rod 22 on the connecting rod 21, and the workpiece is positioned by four limit members 23.
