Description

Technical Field

[0002] In the processing and production of plastic pipes, tensile properties are one of the key indicators for measuring product quality, directly affecting the reliability and safety of the plastic pipes in subsequent use. Therefore, it is essential to conduct rigorous tensile testing on the processed plastic pipes to ensure they meet relevant standards and requirements. Existing tensile testing devices for plastic pipe processing have at least the following drawbacks: 1. Traditional tensile testing devices for plastic pipe processing have poor fixing effects on the plastic pipes. During tensile testing, the plastic pipes are prone to slippage, which not only affects the accuracy of the test data but may also cause safety hazards due to the plastic pipes falling off; 2. When testing plastic pipes of different lengths, existing tensile testing devices for plastic pipe processing often require changing the corresponding clamps or adjusting the device structure, which is cumbersome and reduces testing efficiency. Therefore, we have introduced a new tensile testing device for plastic pipe processing. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Please see Figure 1-4 This utility model provides a technical solution: A tensile testing device for processing plastic pipes includes a support base plate 1, a support ring 2 fixedly connected to the upper left part of the support base plate 1, a fixed frame 3 fixedly connected to the upper left part of the support base plate 1, a fixed block 4 fixedly connected to the upper right part of the fixed frame 3, a telescopic cylinder 6 fixedly connected to the lower end of the fixed block 4, a first card frame 7 fixedly connected to the output end of the telescopic cylinder 6, a first support plate 5 fixedly connected to the lower right part of the fixed frame 3, and the first support plate 5 fixedly connected to the support base plate 1, and a slide structure 9 fixedly connected to the upper end of the support base plate 1, with a tensile component 8 sleeved on the outer surface of the slide structure 9; In this embodiment, the slide structure 9 includes a first slide 91, and there are two first slides 91. The outer surfaces of the two first slides 91 are fitted with a slide frame 92. The lower front end of the slide frame 92 is fixedly connected to a second positioning block 95. The upper end of the slide frame 92 is fixedly connected to a U-shaped frame 93. The lower front end and the lower rear end of the U-shaped frame 93 are both fixedly connected to a first positioning block 94. Both first slides 91 are fixedly connected to the support base plate 1. The lower inner frame wall of the U-shaped frame 93 is flush with the lower inner groove wall of the lower slot 825.

[0019] The above scheme provides support for the movement of the sliding frame 92 via two sliding tables 91, and also supports the use of the tensioning component 8. The U-shaped frame 93 supports the plastic pipe, improving stability.

[0020] In this embodiment, the stretching assembly 8 includes an electric push rod 81, the output end of which is fixedly connected to a support plate 82. A cylinder 84 is fixedly connected to the left end of the support plate 82, and a horizontal plate 83 is fixedly connected to the upper part of the left end of the support plate 82. An adjusting screw 85 is inserted through the middle of the upper end of the horizontal plate 83. The electric push rod 81 is fixedly connected to the support base plate 1. The support plate 82 includes a slide plate 821, and a second slide table 823 is fixedly connected to the front and rear of the left end of the slide plate 821. A second retaining frame 824 is sleeved on the outer surface of the two second slide tables 823. A second support plate 822 is fixedly connected to the lower part of the left end of the slide plate 821. A retaining groove 825 is opened at the upper end of the second support plate 822 and the lower end of the second retaining frame 824. The slide plate 821 is fixedly connected to the electric push rod 81. The adjusting screw 85 passes through the horizontal plate 83 and contacts the upper end of the second retaining frame 824. The slide plate 821 is sleeved on both first slide tables 91.

[0021] The above solution involves fixing anti-slip rubber layers to the inner walls of the two slots 825, the inner frame wall of the first support plate 5, and the inner frame wall of the first card frame 7. These anti-slip rubber layers are tightly attached to the surface of the plastic tube, which can strengthen the connection between the tensile component 8 and the plastic tube, and at the same time strengthen the connection between the first support plate 5 and the first card frame 7, thus facilitating subsequent tensile testing.

[0022] It should be noted that this utility model is a tensile testing device for processing plastic pipes. When using this tensile testing device, the plastic pipe to be tested is first passed sequentially through the fixed frame 3 and the first support plate 5. The fixed frame 3 serves as a preliminary positioning and guide, allowing the plastic pipe to enter the testing device along a predetermined path. The first support plate 5 provides a stable support base for subsequent clamping operations, ensuring that the plastic pipe remains horizontal or in a predetermined position during installation. Next, the plastic pipe is inserted and connected to the U-shaped frame 93, and then the plastic pipe is fitted onto the cylinder 84. The combined design of the U-shaped frame 93 and the cylinder 84 further fixes the position of the plastic pipe, preventing it from shifting during subsequent... During the tensile testing process, any shaking or shifting occurs, preparing for the subsequent secure connection between the tensile assembly 8 and the plastic tube. By rotating the adjusting screw 85, utilizing the threaded transmission principle, the horizontal plate 83 slides along a specific direction on the two secondary slide tables 823. The secondary slide tables 823 provide precise guidance and support for the sliding of the horizontal plate 83, ensuring that the horizontal plate 83 can move smoothly and accurately. As the horizontal plate 83 slides, the slots 825 on the secondary clamping frame 824 gradually approach and eventually fit tightly against the surface of the plastic tube. The anti-slip rubber layer set inside the slots 825 increases the friction with the surface of the plastic tube, preventing relative sliding between the plastic tube and the secondary clamping frame 824 during the tensile process. To enhance the stability of the connection between the tensile component 8 and the plastic tube and ensure the accuracy of the tensile test, the telescopic cylinder 6 is activated. The piston rod of the telescopic cylinder 6 extends, generating a pushing force on the first clamping frame 7. This causes the first support plate 5 and the first clamping frame 7 to move closer to and clamp the plastic tube. The inner frames of the first support plate 5 and the first clamping frame 7 are also equipped with anti-slip rubber layers, which firmly fix the plastic tube when in contact with its surface, ensuring that the plastic tube will not slip off the clamping point during the tensile test. This provides reliable clamping protection for subsequent tensile tests. After clamping the plastic tube, the electric push rod 81 applies tension to the support plate 82. The support plate 82 is connected to the tensile component 8. The pulling action of the push rod 81 causes the tensioning assembly 8 to cause the plastic tube to undergo tensile deformation. During this process, the tensile condition of the plastic tube, such as tensile force and deformation, can be monitored in real time by an external sensor detection device, thereby completing the tensile test of the plastic tube. The pipe hole set on the fixed frame 3 provides an installation channel for pipes of different lengths. When performing tensile testing, the plastic tube can be flexibly installed and fixed by passing it through the pipe hole according to its actual length. This design enables the tensile testing device to adapt to the testing needs of plastic tubes of various lengths, improving the flexibility and versatility of the device and reducing the trouble of changing testing equipment due to different pipe lengths.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
