Plastic water supply pipe production line flaring machine chuck

Abstract

The invention discloses a plastic water supply pipe production line flaring machine chuck, which comprises a connecting rod (1), a movable seat (2), and a fixed seat (5). The connecting rod (1) is welded on the movable seat (2). The chuck is characterized in that: a trapezoidal rubber block (3) is mounted on the movable seat (2), a trapezoidal plastic block (4) is installed on the fixed seat (5), the trapezoidal rubber block (3) is provided with a trapezoidal groove I (31) and a bulge I (32), the trapezoidal plastic block (4) is provided with a trapezoidal groove II (41) and a bulge II (42), the movable seat (2) is equipped with a groove having a shape and size matching with the bulge I (32), and the fixed seat (5) is provided with a groove having a shape and size matching with the bulge II (42). The chuck provided by the invention has the advantages of simple structure, convenient assembly and disassembly, reliable clamping, low cost, and long service life.

Description

technical field [0001] The invention relates to production equipment for plastic water supply pipes, in particular to a chuck of a flaring machine for a production line of plastic water supply pipes. Background technique [0002] When the flaring machine in the existing plastic water supply pipe production line expands the plastic water supply pipe, it needs to use the chuck to compress the plastic water supply pipe first, and then expand the port of the plastic water supply pipe through the expansion die. The diameter of the plastic water supply pipe is different, and it is necessary to make multiple sets of chucks according to the diameter of the plastic water supply pipe. The chuck is composed of a steel upper chuck and a lower chuck. Then, according to the diameter of the plastic water supply pipe produced Replacement of the chuck, using such a structure, there are the following problems: 1. Due to the error in the production of the plastic water supply pipe, it is easy ...

AI Technical Summary

Problems solved by technology

[0002] When the flaring machine in the existing plastic water supply pipe production line expands the plastic water supply pipe, it needs to use the chuck to compress the plastic water supply pipe first, and then expand the port of the plastic water supply pipe through the expansion die. The diameter of the plastic water supply pipe is different, and it is necessary to make multiple sets of chucks according to the diameter of the plastic water supply pipe. The chuck is composed of a steel upper chuck and a lower chuck. Then, according to the diameter of the plastic water supply pipe produced Replacement of the chuck, using such a structure, there are the following problems: 1. Due to the error in the production of the plastic water supply pipe, it is easy to cause the chuck to not press the plastic water supply pipe tightly due to the small diameter of the plastic water supply pipe or the diameter of the plastic water supply pipe is too small. If the chuck is too large, the plastic water supply pipe may be crushed by the chuck; 2. Multiple sets of chucks need to be produced, which is costly; 3. When replacing the chuck, it is labor-intensive and time-consuming, which affects production efficiency
