Description

Technical Field

[0001] This utility model relates to the field of impact testing technology, and in particular to a pendulum impact testing machine for plastic testing. Background Technology

[0002] The pendulum impact tester is used to test the impact resistance of metallic and non-metallic materials under dynamic loads, in order to determine the properties of the material under dynamic loads. The pendulum impact tester's punch impacts and passes through the specimen at a certain speed, and the energy consumed by the punch is measured to evaluate the pendulum impact resistance. Currently, plastics need to be tested for impact resistance using a pendulum impact tester during production. During use, the specimen is clamped on a support platform near the bottom of the support, and the pendulum swings down from a height to impact the specimen, breaking it, and obtaining a series of measurement parameters at the time of impact.

[0003] When struck by a pendulum, the broken specimen is prone to flying out at high speed along the pendulum's swing trajectory, which is detrimental to the safety of nearby operators. Protective nets are usually placed, but when the specimen breaks and flies out during the test, the plastic parts are prone to rebound, reducing the protective performance of the nets and resulting in low safety performance. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] To address the issue that plastic parts break and fly out during specimen fracture tests, easily rebounding and reducing the protective performance of the safety net, resulting in lower safety performance.

[0006] (2) Technical solution

[0007] The technical solution of this utility model is as follows: a pendulum impact testing machine for plastic testing, comprising a device body, including a base, a pendulum impact testing machine body, a protective collection assembly, a clamping and fixing assembly, and a control panel. The pendulum impact testing machine body is located in the middle of the device body. A base is fixed below the pendulum impact testing machine body. A protective collection assembly is provided on one side of the base surface of the pendulum impact testing machine body. A clamping and fixing assembly is installed on the surface of the pendulum impact testing machine body. A control panel is installed on the surface of the pendulum impact testing machine body via a mounting base. A fixed frame and a protective frame are sequentially installed on one side of the pendulum impact testing machine body, and a baffle is provided on the other side of the fixed frame. The broken specimen flies out and impacts the protective net installed on the baffle, which effectively reduces the impact force of the broken specimen and prevents it from rebounding, thus improving operational safety. When the broken specimen is resisted by the protective net, it falls into the groove inside the baffle for collection and unified processing. When cleaning is required, the baffle is pulled to remove the slider from the mounting block, thereby achieving the purpose of cleaning the broken specimen. The structure is simple, the protective effect is good, and the operational safety is improved. With the help of the clamping and fixing components, when in use, the handle on the turntable is rotated to drive the moving blocks at both ends of the two-way lead screw to move, which in turn drives the clamping blocks installed on the moving blocks to clamp the plastic parts. The structure is simple, the operation is convenient, and it can provide a good clamping effect, improving the accuracy of testing plastic parts.

[0008] Furthermore, the protective collection assembly includes a fixed frame, a protective frame, a baffle, a protective net, mounting blocks, sliders, and grooves. A fixed frame is mounted on one side of the base, adjacent to the main body of the pendulum impact testing machine. A baffle is positioned below the fixed frame, with a concave structure below it. Soft protective nets are installed in the through grooves on the baffle surface. Two sliders with a convex structure are symmetrically mounted on the inner surface of the baffle. Two mounting blocks are mounted on the surface of the fixed frame at positions corresponding to the sliders. Grooves adapted to the sliders are formed on the surface of the mounting blocks. The baffle slides on the surface of the fixed frame via the sliders and grooves. A protective frame is fixedly mounted on the side of the fixed frame closest to the main body of the pendulum impact testing machine. The protective frame has through grooves on its surface that fit the swing arm of the pendulum impact testing machine. By setting up a protective collection component, a fixed frame and a protective frame are installed sequentially on one side of the pendulum impact testing machine, and a baffle is set on the other side of the fixed frame. When the broken specimen flies out and hits the protective net installed on the baffle, the impact force of the broken specimen can be effectively reduced, preventing the broken specimen from rebounding and improving operational safety. When the broken specimen is resisted by the protective net, it falls into the groove inside the baffle for collection and unified processing. When cleaning is required, the slider is pulled out from the mounting block by pulling the baffle, thereby achieving the purpose of cleaning the broken specimen. The structure is simple, the protective effect is good, and the operational safety is improved.

[0009] Furthermore, a strong magnetic block is installed in the groove at one end of the slider. The strong magnetic block is magnetically attracted to the inner wall of the mounting block. By installing the strong magnetic block at one end of the slider, the baffle can be fixed to the surface of the fixed frame, making it easy to use and clean.

[0010] Furthermore, the surface of the base is provided with a fixing block in the shape of a triangular block below the protective frame. The fixing block in the shape of a triangular block can play a good guiding role during the flight of the broken specimen.

[0011] Furthermore, a ribbon is fixedly installed on the upper inner wall of the fixed frame. By installing the ribbon inside the fixed frame, when the plastic part is subjected to a pendulum impact test, the broken specimen flies out and hits the ribbon, which can effectively reduce the impact force of the broken specimen, effectively buffer the specimen, prevent the specimen from rebounding, and further improve the safety of the device.

[0012] Furthermore, the clamping and fixing assembly includes a fixed base, a groove, a bidirectional lead screw, a moving block, a clamping block, a turntable, and a handle. A fixed base is installed at the lower center of the pendulum impact testing machine body. A groove is formed on the surface of the fixed base, within which a bidirectional lead screw rotates. Moving blocks are screwed to both ends of the bidirectional lead screw. A clamping block is installed above the moving blocks, and its surface is coated with an anti-slip granular layer. A turntable is installed at one end of the bidirectional lead screw that passes through the fixed base. A handle is installed on the surface of the turntable. By setting up the clamping and fixing assembly, during use, rotating the handle on the turntable moves the moving blocks at both ends of the bidirectional lead screw, thereby causing the clamping blocks installed on the moving blocks to clamp the plastic parts. The structure is simple, the operation is convenient, and it provides excellent clamping effect, improving the accuracy of testing plastic parts.

[0013] Furthermore, the movable block is designed with a convex shape, and the groove on the surface of the fixed base is adapted to the movable block. The convex shape of the movable block can improve the clamping stability of the clamping block on the plastic part and prevent loosening.

When the broken specimen flies out and hits the protective net installed on the baffle, it can effectively reduce the impact force of the broken specimen, avoid the broken specimen from rebounding, and improve the safety of operation.

[0017] 2. When the broken parts are resisted by the protective net, they fall into the groove inside the baffle for collection and unified processing. When cleaning is required, the baffle is pulled to remove the slider from the mounting block, thereby achieving the purpose of cleaning the broken parts.
