Description

Technical Field

[0001] This utility model belongs to the field of engineering plastics testing technology, specifically relating to an engineering plastics toughness testing device. Background Technology

[0002] The background technology, development history, and application scenarios of plastics are very rich and diverse. The development of the plastics industry began in the late 19th century and has a history of more than 120 years. Initially, the development of plastics focused on the modification and processing of natural polymers. For example, in 1869, American J.W. Hyatt invented celluloid, a plastic material made of nitrocellulose, camphor, and a small amount of alcohol. This invention marked the birth of the plastics industry and promoted the development of compression molding technology.

[0003] Application No. 202320188995.3 discloses a special engineering plastic performance testing device, which relates to the field of plastic testing technology, and particularly to a special engineering plastic performance testing device. It mainly addresses the current problem that strength and hardness testing of sheet-like special engineering plastics after production is mostly done manually, and the device requires pre-positioning during testing, which easily reduces the testing speed. The proposed technical solution includes a base, with support legs mounted on the top of the base, and a top plate connected to the top of the support legs. A support mechanism for holding the sheet-like special engineering plastics is provided on the top of the base. This utility model achieves fixed positioning of sheet-like special engineering plastics of different sizes, and can simultaneously test the hardness of sheet-like special engineering plastics of different sizes without manual positioning, avoiding the slowdown caused by manual positioning.

[0004] While the aforementioned document details the strength and hardness test results of engineering plastics, it unfortunately does not include a function to test the toughness of plastics. Toughness is an important indicator for measuring the impact resistance and fracture resistance of plastics. Its absence may lead to an incomplete assessment of material properties in practical applications, thereby affecting the accuracy of engineering design and the safety of material selection. Therefore, an engineering plastic toughness testing device has emerged. Utility Model Content

[0014] As a preferred embodiment of the present invention, the locking assembly further includes a second pin slidably connected to the inner cavity of the locking block, and a locking post fixedly installed on the inner surface of the locking frame.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: through the cooperation of the clamping component, the moving component, and the locking component, efficient and stable clamping and precise force control of engineering plastics are achieved.

[0025] Example

[0026] Reference Figures 1-4 This is an embodiment of the present invention, which provides an engineering plastic toughness testing device, comprising,

[0027] The mounting housing 101, the support rod 102 fixedly mounted on the inner wall of the mounting housing 101, the mounting groove 103 formed on the inner wall of the mounting housing 101, the clamping assembly 104 disposed in the inner cavity of the mounting housing 101, the moving assembly 105 disposed on the inner surface of the mounting housing 101 and used in conjunction with the clamping assembly 104, and the engaging assembly 106 disposed on the surface of the mounting housing 101 and used in conjunction with the moving assembly 105.

[0028] The clamping assembly 104 includes a fixing block 104a fixedly installed on the inner wall of the mounting housing 101, a limiting rod 104b fixedly installed on the side wall of the fixing block 104a, a clamping block 104c slidably connected to the outer surface of the limiting rod 104b, and a lead screw 104d that penetrates the inner cavity of the fixing block 104a. The clamping assembly 104 also includes a connecting block 104e connected to the end of the lead screw 104d by a bearing, and a first pin 104f slidably installed in the inner cavity of the connecting block 104e.

[0029] Specifically, there are two clamping blocks 104c and two limiting rods 104b. The limiting rods 104b are symmetrically arranged at both ends of the fixed block 104a, and the clamping blocks 104c are symmetrically arranged at both ends of the limiting rods 104b. When the lead screw 104d rotates, the clamping blocks 104c rotate in the opposite direction.

[0030] The movable assembly 105 includes a bearing seat 105a fixedly installed on the inner wall of the mounting groove 103, a synchronizing rod 105b fixedly installed on the outer surface of the bearing seat 105a, and a movable frame 105c sleeved on the outer surface of the synchronizing rod 105b. The movable assembly 105 also includes an insert block 105d fixedly installed on the inner wall of the movable frame 105c, an insertion hole 105e provided on the outer surface of the insert block 105d, and a movable groove 105f opened on the side wall of the insert block 105d.

[0031] Furthermore, the insert 105d can be used in conjunction with the second pin 106d, and can also be used in conjunction with the first pin 104f to achieve the maximum value of testing the toughness of engineering plastics.

[0032] The locking assembly 106 includes a slider 106a slidably connected to the inner wall of the movable groove 105f, a locking frame 106b fixedly connected to the side wall of the slider 106a, and a locking block 106c fixedly installed on the side wall of the locking frame 106b. The locking assembly 106 also includes a second pin 106d slidably connected to the inner cavity of the locking block 106c, and a locking post 106e fixedly installed on the inner surface of the locking frame 106b.

[0033] Preferably, there are three clamping posts 106e, with two intervals between them. The strength tested varies depending on the interval between the insertions.

[0034] In use, move the engaging assembly 106 to move the locking post 106e above the locking block 106c. Insert the engineering plastic to be tested into the gap between the locking posts 106e. The plastic is locked in the gap between the locking posts 106e. Place the other end of the plastic between the locking blocks 106c. Move the lead screw 104d. The lead screw 104d rotates, causing the locking block 106c to slide on the outer surface of the limit rod 104b, fixing the plastic in place. Move the moving frame 105c. The moving frame 105c rotates around the bearing seat 105a as the axis. The insertion block 105d on the moving frame 105c and the locking block 106e... When c is parallel, insert the second pin 106d into the insert block 105d and observe whether cracks appear on the plastic surface over time. To enhance the test strength, remove the second pin 106d, move the moving frame 105c, and the slider 106a moves forward in conjunction with the movable groove 105f, driving the moving frame 105c forward. The slider 106a is set with rounded corners and rotates in the movable groove 105f. When the locking block 106c on the moving frame 105c is parallel to the connecting block 104e, insert the first pin 104f into the locking hole in the locking block 106c and continue to penetrate the plastic surface to see if cracks appear.

[0035] In summary, accurate testing of the toughness of engineering plastics was achieved. The ingenious design of the locking assembly 106 and the synergistic effect of components such as the lead screw 104d, the moving frame 105c, and the insert block 105d ensured the stability of the plastic during fixing and stress application. This structural design not only effectively observes whether cracks appear in the plastic during stress application but also allows for flexible enhancement of the test intensity by adjusting the position of the insert pin, thus comprehensively evaluating the toughness of the plastic. The rounded corner design and rotational motion of the slider 106a reduce friction and damage, improving the accuracy and repeatability of the test and providing reliable data support for the application of engineering plastics.
