Description

Technical Field

[0001] This utility model relates to the field of compressive strength testing technology, specifically to a compressive strength testing device for sheet metal. Background Technology

[0002] PC sheet, or polycarbonate sheet, is a high-performance plastic sheet widely used in construction, automotive, and electronics industries. The production process of PC sheet is complex and precise, involving multiple stages such as raw material preparation, extrusion molding, stretching, cooling and shaping, post-processing, and quality inspection. Each step requires strict quality control and process parameter management to ensure the high performance and high quality of the final product. One quality inspection test is the compressive strength test, which measures the compressive strength of the sample by applying pressure to its center point.

[0003] Chinese Patent Publication No. CN118654989A discloses an integrated testing device for cement flexural and compressive strength, relating to the field of cement quality testing. The device includes a testing frame, a compression table, and an extrusion disc. A flexural strength testing component is slidably connected to the compression table, and a support plate is also slidably connected to the compression table to support the cement. A first driving component on the testing frame drives the compression table to move up and down, while a second driving component on the compression table drives the flexural strength testing component to move up and down. When a cement sample is placed on the support table, the first driving component raises the compression table, causing the support plate and extrusion disc to compress the cement for compressive strength testing. When the cement sample is placed in the flexural strength testing component, the second driving component moves the flexural strength testing component up and down, causing the extrusion disc to press against the support table, which in turn applies pressure to the flexural strength testing component for flexural strength testing. This device can test both cement compressive and flexural strength, improving functionality and testing efficiency.

[0004] However, the above-disclosed technical solution has the following shortcomings: when the sample breaks during the compressive strength test, it will produce debris, which will be scattered everywhere and require manual cleaning, which increases the workload and reduces the testing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art where sample fragments are scattered in various places and require manual cleaning, and to propose a plate compressive strength testing device.

[0006] The technical solution of this utility model is: a plate compressive strength testing device, comprising a plate, and further comprising:

[0009] The lifting device is vertically installed on the inner wall of the top of the gantry frame, and the telescopic end of the lifting device is connected to a pressure testing mechanism.

[0010] The upper pressure box is slidably mounted on the top of the gantry in a vertical direction. The pressure testing mechanism and the lifting device are located inside the upper pressure box. A test port is set at the bottom of the upper pressure box. A fixing plate is set on the inner wall of the upper pressure box. A support plate is set on the telescopic end of the lifting device.

[0014] Preferably, it also includes a bracket with two support rollers placed on it. The two support rollers are located on the front and rear sides of the gantry frame, respectively, and the bottom of the plate is in contact with the two support rollers.

[0015] Preferably, it also includes a vertical plate that is slidably mounted on the gantry frame in the horizontal direction. Two push rods are provided on the end face of the vertical plate facing the plate. When the vertical plate slides to the left, the push rods push the plate to the left, so that the plate is disengaged from the lower support box.

A motor is installed on the gantry frame, and the output shaft of the motor is horizontally connected to a screw. A threaded hole that mates with the screw is provided on the vertical plate.

[0017] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: the upper pressure box first presses on the plate, and the plate is fixed in position by the upper pressure box and the lower support box. The telescopic end of the lifting device continues to descend, the spring is compressed, and the pressure plate passes through the detection port and presses on the plate. As the pressure increases, the plate breaks, and the debris passes through the slag receiving port and slides into the slag receiving box through the guide plate. The debris does not need to be cleaned manually, which is convenient to use. Moreover, due to the presence of the lower support box and the upper pressure box, the debris will not splash, and the pressure resistance test is safer. Attached Figure Description

[0031] Example 2

[0032] like Figures 3-4 As shown, this utility model proposes a plate compression testing device. Compared with Embodiment 1, this embodiment details the structure of the compression testing mechanism.

[0033] The pressure testing mechanism includes a lifting block 17 located at the bottom of the lifting device 10, a pressure testing device 16 located at the bottom of the lifting block 17, and a pressure plate 14 slidably mounted on the lifting block 17 in a vertical direction.
