Composite microporous structure magnesium carbon brick strength detection punch

Abstract

This utility model relates to the field of magnesia-carbon brick technology, and more particularly to a composite microporous structure magnesia-carbon brick strength testing punch. The punch includes a cylindrical connector, a disc-shaped central seat fixed to the lower wall of the connector, and a cylindrical fixing seat at the lower end of the central seat. The fixing seat has a threaded opening and an opening. A screw is threaded into the threaded opening, and a connecting post movably connected to the opening is fixed to the lower wall of the screw. A pointed tip for pressing the end wall of the magnesia-carbon brick is fixed to the lower wall of the connecting post. In this utility model, an iron bar or iron post is inserted into the connecting hole at the pointed tip and bent, thereby driving the pointed tip to rotate, causing the screw and connecting post to rotate synchronously. The screw and threaded opening drive each other, facilitating the downward movement of the connecting post and the pointed tip, increasing the depth of penetration into the magnesia-carbon brick during testing, and thus providing greater controllability and adjustability during testing.

Description

Technical Field

[0001] This utility model relates to the field of magnesia-carbon brick technology, and in particular to a strength testing punch for magnesia-carbon bricks with a composite microporous structure. Background Technology

[0002] Magnesia-carbon bricks are made from high-melting-point alkaline oxide magnesium oxide (melting point 2800℃) and high-melting-point carbon materials that are difficult to be wetted by slag, with the addition of various non-oxide additives. When testing magnesia-carbon bricks, a hydraulic press is used to drive a punch to squeeze the end wall of the magnesia-carbon brick to test its strength.

[0003] Magnesia-carbon brick testing punches have a simple structure, consisting of a common cylindrical shape with a sharp end, used to press the end wall of magnesia-carbon bricks. However, when testing magnesia-carbon bricks, which have a certain thickness, the fixed end size of ordinary testing punches prevents them from detecting the deeper layers of the magnesia-carbon bricks. Utility Model Content

[0004] The purpose of this invention is to provide a punch for testing the strength of composite microporous magnesium-carbon bricks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A composite microporous structure magnesia-carbon brick strength testing punch includes a cylindrical connector, a disc-shaped center seat fixed to the lower end wall of the connector, a cylindrical fixing seat at the lower end of the center seat, a threaded opening and an opening inside the fixing seat, a screw threadedly connected to the threaded opening, a connecting post fixed to the lower end wall of the screw and movably connected to the opening, and a pointed tip for pressing the end wall of the magnesia-carbon brick fixed to the lower end wall of the connecting post.

[0007] Preferably, a circular connecting hole is provided through the pointed end wall.

[0008] Preferably, the end wall of the fixing seat has an outer channel in a ring shape, and the top wall of the fixing seat is fixedly connected with a screw head.

[0009] Preferably, a rectangular notch is provided at the bottom end wall of the central seat.

[0010] Preferably, the connector has a rectangular bottom groove that extends into the center seat and communicates with the recess.

[0011] Preferably, a rectangular sponge seat is engaged at the bottom groove of the connector.

[0012] This utility model has at least the following beneficial effects:

[0013] An iron bar or iron column is inserted into the connecting hole at the tip and bent to drive the tip to rotate, causing the screw and connecting column to rotate synchronously. The screw and threaded end drive each other, which facilitates the downward movement of the connecting column and tip, increasing the depth of the magnesia-carbon brick being pressed down during testing. This makes the testing process more controllable and adjustable. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a composite microporous structure magnesia-carbon brick strength testing punch:

[0022] like Figure 1-4As shown, a composite microporous structure magnesia-carbon brick strength testing punch includes a cylindrical connector 1, a disc-shaped center seat 2 fixedly connected to the lower end wall of the connector 1, a cylindrical fixing seat 3 provided at the lower end of the center seat 2, a threaded port 4 and an opening 7 opened inside the fixing seat 3, a screw 5 threadedly connected inside the threaded port 4, a connecting post 6 fixedly connected to the lower end wall of the screw 5 and movably connected to the opening 7, and a pointed tip 8 for pressing the end wall of the magnesia-carbon brick fixedly connected to the lower end wall of the connecting post 6.

[0023] A circular connecting hole 9 runs through the end wall of the pointed tip 8;

[0024] The fixed seat 3 has an outer channel 10 in a ring shape on the end wall, and a screw head 14 is fixed to the top wall of the fixed seat 3. The center seat 2 has a rectangular notch 12 on the bottom wall.

[0025] The connector 1 has a rectangular bottom groove 11 that extends into the center seat 2 and communicates with the recess 12. A rectangular sponge seat 13 is engaged at the bottom groove 11 of the connector 1.

[0026] Working principle:

[0027] When in use, connect connector 1 to the end of the hydraulic cylinder transmission component of the hardness tester. Generally, the hydraulic cylinder of the tester is connected to a transmission rod, and a three-jaw clamp is connected to the transmission rod for connecting cylindrical instruments, i.e., this connector 1.

[0028] After connection, under the transmission of the hydraulic cylinder, the connector 1, center seat 2, fixed seat 3 and tip 8 move down. The tip 8 squeezes the end wall of the magnesia-carbon brick, generating an impact, thereby detecting the hardness of the end wall of the magnesia-carbon brick.

[0029] Among them, an iron bar or iron column is inserted into the connecting hole 9 at the tip 8 and bent, thereby driving the tip 8 to rotate, so that the screw 5 and the connecting column 6 rotate synchronously. The screw 5 and the threaded port 4 drive each other, which facilitates the downward movement of the connecting column 6 and the tip 8, increases the depth of the magnesia-carbon brick being pressed down when the connecting column 6 and the tip 8 are being tested, and thus makes the test more controllable and adjustable.

[0030] An outer channel 10 is provided at the end wall of the fixed seat 3 to facilitate liquid flow when flushing liquid toward the fixed seat 3.

[0031] First, the screw head 14 has a circular opening extending into the fixed seat 3, which is connected to the threaded opening 4. The center seat 2 and the fixed seat 3 are connected together in a disassembly and assembly manner. In use, the center seat 2 and the fixed seat 3 are connected together by the screw head 14 and the recess 12, which facilitates their disassembly and assembly. After disassembly, lubricating fluid is poured into the recess 12, which is absorbed by the sponge seat 13 made of sponge material. Then, the center seat 2 and the fixed seat 3 are assembled. After that, the lubricating fluid flows slowly down along the circular opening to lubricate and maintain the screw 5, the connecting post 6, and the tip 8 in sequence.

[0032] 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 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 claimed utility model.
