Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware pipe limiting clamps technology, specifically a limiting clamp for hardware pipe processing. Background Technology
[0002] Hardware can generally be understood as "metal products," including various metal tools, metal fittings, and other metal items. Pipes, on the other hand, are hollow tubular materials, such as square, round, or other cross-sectional shapes. Hardware pipes are mainly classified into two categories based on their material: metal pipes and non-metal pipes. During processing, hardware pipes require clamps to hold and fix them in place, and then are shaped through cutting or punching processes.
[0003] Existing hardware pipe limiting clamps typically clamp both ends of the pipe. However, during pipe cutting or punching, the inner wall of some pipes is relatively thin, making them susceptible to deformation due to compression. This reduces the quality of the finished product and consequently lowers the overall performance of the device. Utility Model Content

A sliding block 56 is connected to the bottom of the hollow tube 51, and the sliding block 56 is slidably connected to the track groove 2. A limiting block 55 is connected to the left side of the hollow tube 51 via a bearing with a seat.
[0026] Please see Figure 3 and Figure 4 Hollow tube 51 can guide push plate 52. Push plate 52 can drive limit plate 54 to move through connecting rod 57. Limit plate 54 can support and fix the inner wall of tube. Guide arm 59 can guide limit plate 54 to make it move linearly.
