Detailed Description
Referring to fig. 1-3, the fixing mechanism for plastic pipe connection drawing test provided by the utility model comprises a mounting plate 2, two fixing blocks 3 and a driving unit 4, wherein the driving unit 4 is fixed on the mounting plate 2, the driving unit 4 is in driving connection with the fixing blocks 3 to drive the two fixing blocks 3 to be mutually close or far away in the horizontal direction, when the two fixing blocks 3 are mutually close, the plastic pipe 1 is clamped between the two fixing blocks 3, and the front ends of the fixing blocks 3 are provided with tip parts 31.
In the above embodiment, the driving unit 4 drives the fixing blocks 3 to approach the plastic tube 1 between the two fixing blocks 3, when the tip end portion 31 abuts against the plastic tube 1, the plastic tube 1 is clamped and fixed between the two fixing blocks 3, and the friction force between the fixing blocks 3 and the plastic tube 1 can be increased due to the arrangement of the tip end portion 31.
However, when the drawing force during the drawing test is greater than the friction force between the plastic pipe fitting 1 and the fixed block 3, the plastic pipe fitting 1 will be separated from the fixed block 3, so as to affect the drawing test, and in order to solve the above problem, the heating wire 311 is installed in the tip end portion 31, and the tip end portion 31 is made of metal heat conducting material.
The number of the fixing mechanisms in the drawing test is two, and one group of the fixing mechanisms is connected with an external hydraulic lifting mechanism so as to drive the two groups of the fixing mechanisms to be close to or far away from each other, and the two groups of the fixing mechanisms are respectively used for fixing two plastic pipe fittings 1 which are connected together;
the drawing test process is specifically as follows: firstly, the plastic pipe fitting 1 with two ends connected together is placed between two fixing blocks 3 in two groups of fixing mechanisms, a driving unit 4 drives the fixing blocks 3 to approach the plastic pipe fitting 1 along the horizontal direction, a heating wire 311 is started, a tip end portion 31 is heated, when the tip end portion 31 on the fixing block 3 is in contact with the outer wall of the plastic pipe fitting 1, the outer wall of the plastic pipe fitting 1 is heated and melted, a groove is formed on the outer wall of the plastic pipe fitting 1 along with the horizontal pushing of the fixing block 3, the heating wire 311 is closed, after the tip end portion 31 and the plastic pipe fitting 1 are cooled, the fixing block 3 is clamped in the groove formed by hot melting of the plastic pipe fitting 1 in the horizontal direction, at the moment, the fixing block 3 is horizontally inserted into the inner wall of the plastic pipe fitting 1, and accordingly the plastic pipe fitting 1 and the fixing block 3 are relatively fixed in the length direction of the plastic pipe fitting 1, and the plastic pipe fitting 1 are prevented from being separated in a drawing test.
It should be further noted that the depth of the fixing block 3 protruding into the plastic tube 1 is smaller than the wall thickness of the plastic tube 1.
The provision of the tip portion 31 also increases the heated area of the plastic pipe member 1, while the tip portion 31 also reduces the forward resistance of the fixing block 3 like a blade.
The drive unit 4 includes, but is not limited to, an electric slider.
If the fixing block 3 is directly connected to the output end of the driving unit 4, the generated heat may be conducted to the driving unit 4 through the fixing block 3 when the heating wire 311 heats, and the driving unit 4 may be damaged when heated, and in order to solve the above-mentioned problem, the rear end of the fixing block 3 has a heat insulation part 32 for isolating the driving unit 4 from the tip part 31.
In addition, when the drawing test is performed on the two plastic pipe fittings 1, the inclined surface on the tip part 31 can decompose the external force born by the fixed block 3, so that the drawing force of the fixed block 3 in the vertical direction is reduced, and the fixed block 3 is better protected.
The fixed block 3 is arc-shaped, and the insertion area of the fixed block 3 and the plastic pipe fitting 1 is increased.
