Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a punching mold for a walking aid tube component. Background Technology

[0002] The walking aid tube has multiple holes. When punching, a single hole is usually punched multiple times, which requires multiple positioning, resulting in low efficiency and easy accumulation of errors. At the same time, the tube is prone to displacement due to vibration during punching, affecting the accuracy of the hole position. In addition, the tube needs to be manually removed after punching, which is not automated enough. Therefore, a punching mold for walking aid tube is proposed. Utility Model Content

[0005] Preferably, it also includes an actuator disposed behind the limiting block for pushing the punched pipe component out of the lower die to facilitate the unloading of the pipe component.

[0006] Preferably, the bottom of the upper mold is provided with several mold guide sleeves.

[0007] Preferably, the top of the lower mold is provided with a plurality of mold guide pillars that are adapted to the mold guide sleeve.

[0008] Preferably, the arc-shaped template and the lower die are provided with a discharge hole adapted to the punching die core for discharging punching waste.

[0009] Preferably, the limiting block is provided with a through hole that moves with the piston rod inside the actuator, and the diameter of the through hole is smaller than the outer diameter of the tube component.

[0010] Preferably, the actuator includes a pneumatic cylinder, a hydraulic cylinder, or an electric actuator.

[0011] This utility model has the following beneficial effects: By setting the punching die core, multiple punches can process simultaneously, improving production efficiency and reducing processing costs; by setting the semi-circular arc pressure plate, the pipe component is fixed on the lower die, preventing the pipe component from jumping and shifting due to the punching pressure during punching, which would lead to breakage of the punching die core and deviation of the punching hole position, thus improving the punching quality of the pipe component. At the same time, by replacing the semi-circular arc pressure plate, it can be adapted to different pipe diameters, increasing the versatility of the mold; by setting the actuator, after the pipe component is punched, the piston rod on the actuator passes through the through hole on the limit block and pushes the pipe component out of the lower die, which facilitates the unloading of the pipe component, improves the degree of automation, and speeds up the production speed.
