Description

Technical Field

[0001] This utility model relates to the field of materials testing technology, and in particular to a constant temperature heating furnace for a high temperature tensile creep testing machine. Background Technology

[0002] A high-temperature tensile creep testing machine is a specialized device used to test the slow plastic deformation properties of materials under high-temperature environments and constant tensile loads over time. It can evaluate the mechanical stability and endurance strength of materials under high-temperature conditions by measuring parameters such as creep strain and fracture time. The use of a constant-temperature heating furnace is necessary because the creep behavior of materials is extremely sensitive to temperature; temperature fluctuations significantly affect the accuracy of test results. The core function of the constant-temperature heating furnace is to provide a stable high-temperature environment that meets the testing requirements. By precisely controlling and maintaining a constant temperature within the furnace, the creep test is ensured under constant thermal load conditions, thus making the obtained material performance data more reliable and valuable.

[0003] The constant-temperature heating furnace for high-temperature tensile creep testing mainly consists of a furnace body structure, heating components, a temperature control device, a sample placement and clamping mechanism, and safety protection components. The furnace body structure includes an insulation layer to reduce heat loss. Heating components, such as resistance heating elements, generate heat. The temperature control device uses sensors and controllers to achieve real-time temperature monitoring and precise adjustment. The sample placement and clamping mechanism ensures the sample is fixed and subjected to tensile stress within the furnace. Safety protection components, such as over-temperature protection and insulation layer protection, ensure safe operation of the equipment. All these components work together to provide a stable and controllable high-temperature environment for material creep testing.

[0004] In existing technologies, some high-temperature tensile creep testing machines use a constant-temperature heating furnace to directly fix the mold on the equipment, which leads to difficulties and time-consuming mold replacement, and cannot quickly adapt to the testing needs of different materials and sizes, thus reducing testing efficiency. Therefore, a constant-temperature heating furnace for a high-temperature tensile creep testing machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a constant temperature heating furnace for a high-temperature tensile creep testing machine, which aims to improve the problem that the existing technology of directly fixing the mold to the equipment leads to difficulties and time-consuming mold replacement, and cannot quickly adapt to the testing needs of different materials and sizes, thus reducing the testing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A constant temperature heating furnace for a high-temperature tensile creep testing machine includes a base cover, a rubber pad fixedly connected to the top of the base cover, a protective shell fixedly connected to the top of the rubber pad, a base plate fixedly connected to the inner wall of the protective shell, a fixed shell fixedly connected to the top of the base plate, a middle crossbeam slidably connected to the front side of the fixed shell, a clamp seat fixedly connected to the front side of the middle crossbeam, a force-applying rod slidably connected to the top of the clamp seat, a force-applying block fixedly connected to the bottom of the force-applying rod, two rotating plates rotatably connected to the bottom of the force-applying block, a limit plate rotatably connected to the adjacent side of each of the two rotating plates, and a limit block slidably connected to the bottom of the clamp seat.

[0008] As a further description of the above technical solution:

[0009] The two sides of the limiting plate are slidably connected to the left and right sides of the limiting block, and the bottom of the limiting block is fixedly connected to a mold.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the clamp seat is fixedly connected to two guide plates, and the left and right sides of the force-applying block are slidably connected to the adjacent side of the two guide plates.

[0012] As a further description of the above technical solution:

[0013] A fixing post is fixedly connected to the top of the clamp seat, and a force-applying ring is fixedly connected to the outside of the force-applying rod;

[0014] As a further description of the above technical solution:

[0015] A spring is fixedly connected to the bottom of the force-applying ring, and the outside of the force-applying ring is slidably connected to the inside of the fixed column;

[0016] As a further description of the above technical solution:

[0017] An emergency stop button is fixedly connected to the top of the base cover, and a hand control box is fixedly connected to the right side of the fixed shell.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, the force-applying rod moves, causing the force-applying block to move, which in turn causes the bottom rotating plate to rotate, allowing the limiting plates on both sides of the rotating plate to disengage from the limiting block. This enables rapid mold replacement. Furthermore, it can shorten equipment downtime, improve material testing efficiency, reduce operational losses, and ensure heating uniformity, thereby ensuring accurate and reliable test data.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 2 and Figure 3This utility model provides an embodiment of a constant temperature heating furnace for a high-temperature tensile creep testing machine, comprising a bottom cover 1, which is installed at the bottom and houses transmission components and electrical components. A rubber pad 2 is fixedly connected to the top of the bottom cover 1, which is placed on the bottom cover 1 to prevent clamps and samples from falling and damaging the surface of the equipment. A protective shell 3 is fixedly connected to the top of the rubber pad 2, which protects the internal heating components and stabilizes their internal parts. A base plate 16 is fixedly connected to the inner wall of the protective shell 3, which supports the equipment components and stabilizes them. A fixed shell 4 is fixedly connected to the top of the base plate 16, which protects the optical rod, ball screw pair, etc., from dust. A middle crossbeam 5 is slidably connected to the front side of the fixed shell 4, which is used for applying load to the sample. The moving part, the front side of the middle crossbeam 5 is fixedly connected to a clamp seat 6, which is used to install clamps. The top of the clamp seat 6 is slidably connected to a force rod 7, which receives the pushing force of the operator to move and stabilize it. The bottom of the force rod 7 is fixedly connected to a force block 8, which receives the pushing force of the force rod 7 to move linearly. The bottom of the force block 8 is rotatably connected to two rotating plates 9, which rotate under the action of the force block 8 to stabilize it. The adjacent sides of the two rotating plates 9 are rotatably connected to limit plates, which receive the rotational force of the rotating plates 9 to move and lock into other parts. The bottom of the clamp seat 6 is slidably connected to a limit block 10, which receives external force and slides at the bottom of the clamp seat 6.

[0028] Reference Figure 2 and Figure 4The two sides of the limiting plate are slidably connected to the left and right sides of the limiting block 10. The limiting plate rotates under the action of the rotating plate 9 to make it stable. The bottom of the limiting block 10 is fixedly connected to the mold 11. The mold 11 receives the limiting block 10 and thus locks it in the fixture seat 6. The inner wall of the fixture seat 6 is fixedly connected to two guide plates 12. The left and right sides of the force application block 8 are slidably connected to the adjacent side of the two guide plates 12. The guide plates 12 allow the two force application blocks 8 to move linearly and make them stable. The top of the fixture seat 6 is fixedly connected to a fixing column, which protects the internal spring-loaded component and makes it stable. A force-applying ring 13 is fixedly connected to the outside of the force-applying rod 7. The force-applying ring 13 receives the pushing force of the force-applying rod 7, thereby moving and stabilizing it. A spring 14 is fixedly connected to the bottom of the force-applying ring 13. The spring 14 moves under the action of the force-applying ring 13, thereby stabilizing it. The outside of the force-applying ring 13 is slidably connected to the inside of the fixed column. The force-applying ring 13 receives the pushing force of the force-applying rod 7, thereby moving and stabilizing it, allowing the force-applying ring 13 to move within the fixed column. An emergency stop button 17 is fixedly connected to the top of the bottom cover 1. Pressing the emergency stop button 17 in an emergency will stop the movement of the crossbeam; rotating it clockwise will reset it. A hand control box 15 is fixedly connected to the right side of the fixed shell 4. The hand control box 15 is used to manually operate the movement of the crossbeam 5.

[0029] Working principle: First, the operator presses the force-applying rod 7, causing it to move. This moves the force-applying block 8 at the bottom, which in turn rotates the rotating plate 9 at the bottom. This causes the rotating plate 9 to move, which in turn moves the limiting plate, disengaging it from the limiting block 10 and allowing the mold 11 to detach. When the force-applying rod 7 applies force, the force-applying ring 13 also compresses the spring 14. When released, the spring 14 returns the component to its original position, thus enabling rapid replacement of the mold 11. In addition, this reduces equipment downtime, improves material testing efficiency, reduces operational losses, and ensures heating uniformity, thereby ensuring accurate and reliable test data.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
