Description

Technical Field

[0001] This utility model belongs to the field of experimental furnace technology, and specifically relates to a high-temperature experimental furnace. Background Technology

[0002] Metallic materials refer to pure metals or alloys used in industrial applications. During the processing and production of metallic materials, they need to be heated and subjected to tensile tests, usually through high-temperature testing furnaces. Existing testing furnaces are equipment used for high-temperature heating of metallic materials during processing and production. After heating, an electric cylinder drives the end plate to move and perform tensile tests on the heated metallic materials. During heating, the properties of the metal are verified in the heating chamber. In existing testing furnaces, after the metal material is placed inside and secured, the end contacts the inner surface of the end plate and is clamped and heated. After heating, the metal material is stretched by driving the heated end plate to move. However, after the metal material is heated, it becomes soft and easily causes the clamping between the metal material and the inner surface of the end plate to become loose, resulting in instability during stretching, or even making it impossible to perform the stretching test. This affects the auxiliary reinforcement and fixation of the end plate during high-temperature heating tests. Therefore, this utility model proposes a high-temperature testing furnace. Utility Model Content

[0003] The purpose of this utility model is to provide a high-temperature testing furnace to solve the problem mentioned in the background art that when the testing furnace is used for heating, the metal material is stretched by driving the heated end plate to move. As a result, the metal material is soft after heating, which easily causes the clamping between the metal material and the inner surface of the end plate to be loose, resulting in loosening and instability during stretching, or even making it impossible to perform the stretching test.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature testing furnace, comprising a main furnace body, the main furnace body including two main furnace bodies and an electrical control box, a connecting shaft provided at one side connection of the two main furnace bodies, end plates mounted on both ends of the interior of each main furnace body via electric cylinders, a fixing plate welded and fixed to the surface of each main furnace body, a handle mounted on the interior of the fixing plate via a rotating shaft, and the main furnace body further comprising: An auxiliary reinforcement mechanism is provided, and the auxiliary reinforcement mechanism includes an auxiliary clamping assembly disposed inside the end plate.

[0006] Preferably, the auxiliary clamping assembly includes a movable groove formed inside the end plate, and an internal tooth clamping plate is provided inside the movable groove, and the internal tooth clamping plate matches the internal structure of the movable groove.

[0007] Preferably, the sliding control component includes a groove formed at the middle position of the upper surface of the end plate, a slider sliding inside the groove, and the bottom end of the slider being fixed to the surface of the internal tooth clamping plate by welding.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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.

[0015] Please see Figures 1 to 5This utility model provides a technical solution: a high-temperature test furnace, including a main furnace body 100, which includes two main furnace bodies 101 and an electrical control box 108. A connecting shaft 102 is provided at one side of the connection between the two main furnace bodies 101.

A handle 104 is installed inside the fixing plate 109 via a rotating shaft. A heating chamber 106 is formed in the middle of the interior of the main furnace body 101. Heating tubes 107 are internally arranged in the heating chamber 106, and the heating tubes 107 are electrically connected to the electrical control box 108 via cables. Locks 105 are fixed to the other side of the two main furnace bodies 101. Metal materials are placed inside the heating chamber 106 and in contact with the inner surface. The ends of the metal materials contact the internal tooth clamping plates 1032 on the inner surface of the end plate 103. The two main furnace bodies 101 are then closed by the connecting shaft 102 and locked in place by the locks 105. The metal materials are heated and subjected to tensile testing by energizing the heating tubes 107. The main body 100 of the high-temperature test furnace is also equipped with: An auxiliary reinforcement mechanism is provided, which includes an auxiliary clamping component disposed inside the end plate 103. A sliding control component is disposed on the upper surface of the auxiliary clamping component, and a screw-in adjustment component is disposed at the connection between the end of the sliding control component and the upper surface of the end plate 103. After the metal material is heated by the main body 100 of the high-temperature test furnace, the auxiliary reinforcement mechanism is used again to reinforce the end of the metal material and the inner surface of the end plate 103, so that it is not easy to loosen during tension and the tensile test is effective.

[0016] In order to facilitate the re-clamping and reinforcement of the heated metal material inside the end plate 103 by means of an auxiliary clamping assembly, in this embodiment, preferably, the auxiliary clamping assembly includes a moving groove 1031 formed inside the end plate 103. An internal tooth clamping plate 1032 is provided inside the moving groove 1031, and the internal tooth clamping plate 1032 matches the internal structure of the moving groove 1031. When the metal material is heated, the internal tooth clamping plate 1032 moves inside the moving groove 1031 to assist in the reinforcement and installation of the metal material, and it is not easy to loosen during stretching.

[0017] In order to facilitate the stable movement and adjustment of the internal tooth clamping plate 1032 by means of the sliding control component, in this embodiment, preferably, the sliding control component includes a groove 1033 opened at the middle position of the upper surface of the end plate 103, a slider 1034 sliding inside the groove 1033, and the bottom end of the slider 1034 is fixed to the surface of the internal tooth clamping plate 1032 by welding. The slider 1034 can slide and adjust inside the groove 1033 to drive the internal tooth clamping plate 1032 to move stably and clamp and fix.

[0018] To facilitate the movement and reinforcement of the slider 1034 and the internal tooth clamping plate 1032 via the screw-in adjustment assembly, in this embodiment, preferably, the screw-in adjustment assembly includes an internally threaded fixing block 1036 welded and fixed at the middle position of the end plate 103. The internally threaded fixing block 1036 is internally threadedly connected to a threaded rod 1035. The end of the threaded rod 1035 is rotatably connected to the inside of the slider 1034 via a rotating ring. The outer surface of the threaded rod 1035 is threadedly connected to a locking nut 1037. The threaded rod 1035 can be rotated inside the internally threaded fixing block 1036 to move and reinforce the slider 1034 and the internal tooth clamping plate 1032. After the installation is tightened and fixed, the locking nut 1037 can be rotated again on the outer surface of the threaded rod 1035 for further reinforcement.

[0019] The heat insulation protection mechanism includes a heat insulation protection component located at the bottom of the fixed plate 109. The heat insulation protection component has fixed installation components at both ends and a heat exhaust component inside. During operation, the heat insulation protection mechanism can provide heat insulation protection for the outer surface of the handle 104 inside the handle 104, making it less likely to cause safety hazards due to contact.

[0020] In order to facilitate heat insulation protection of the outer surface of the handle 104 and ensure safe hand operation through the heat insulation protection component, in this embodiment, preferably, the heat insulation protection component includes a protective plate 1041 welded and fixed to the bottom of the inside of the fixing plate 109. The inside of the protective plate 1041 has a heat insulation groove 1047. After the protective plate 1041 is installed, the handle 104 can be heat-insulated and protected by the protective plate 1041 and the heat insulation groove 1047, so that it is not easy to touch and cause danger when holding it.

[0021] To facilitate the fixed installation and heat insulation protection of the protective plate 1041 using a fixed installation assembly, in this embodiment, preferably, the fixed installation assembly includes an integral plate 1044 integrally disposed at both ends of the inner surface of the protective plate 1041. The integral plate 1044 has an internal threaded hole 1046. The two ends of the fixing plate 109 are threadedly connected with fixing screws 1043 that match the internal threaded hole 1046. After the protective plate 1041 is welded to the inside of the fixing plate 109, the fixing screws 1043 are rotated to penetrate the fixing plate 109 and embed into the internal threaded hole 1046 to reinforce and install the protective plate 1041, thus facilitating the fixed heat insulation protection.

[0022] In order to facilitate the discharge of heat generated inside the protective plate 1041 to the outside during heat insulation protection, in this embodiment, preferably, the heat discharge assembly includes an internal guide plate 1042 fixedly installed inside the heat insulation groove 1047, and heat discharge holes 1045 are equidistantly opened on both sides of the protective plate 1041, and the heat discharge holes 1045 are connected to the inside of the heat insulation groove 1047, so that heat can be drawn from inside the heat insulation groove 1047 to the end through the internal guide plate 1042 and discharged to the outside through the heat discharge holes 1045, which facilitates heat dissipation.

[0023] The working principle and usage process of this utility model are as follows: When using this high-temperature test furnace, the metal material is first placed inside the heating chamber 106 and in contact with the inner surface. The end of the metal material contacts the inner tooth clamping plate 1032 on the inner surface of the end plate 103. Then, the two main furnace bodies 101 are closed by the connecting shaft 102 and locked by the lock 105. At this time, when heating after installation, the heating tube 107 inside the main furnace body 101 is energized by the electrical control box 108. When the heating tube 107 is energized, the metal material is heated. After heating, the electric cylinder drives the end plate 103 to move to the outside, which stretches the metal material, facilitating the test after heating. Then, after the main body 100 of the high-temperature test furnace is heated at high temperature and before stretching, the locking nut 1037 can be rotated open, and the threaded rod 1035 can be rotated again inside the internal threaded fixing block 1036. When the threaded rod 1035 moves forward, it drives the slider 1034 to slide inside the slide groove 1033. When the slider 1034 slides, it drives the internal tooth clamping plate 1032 to move inside the moving groove 1031 until the inner surface of the internal tooth clamping plate 1032 is clamped to the inner surface of the end of the metal material. The locking nut 1037 is rotated again to squeeze and reinforce, and it is convenient to assist in reinforcement and installation after heating. The fixed installation is strengthened until it can no longer deform, so that the metal material is strengthened and fixed. When the end plate 103 moves, it drives the metal material to be reinforced and stretched, which is not easy to cause loosening and falling off. It effectively treats the tensile test and improves the auxiliary reinforcement and fixation of the end plate 103 of the main body 100 of the high-temperature test furnace during the high-temperature heating test. Finally, before the high-temperature test furnace main body 100 is heated, the protective plate 1041 is closed inside the fixed plate 109, and the fixed screw 1043 is rotated to penetrate the fixed plate 109 and embed into the internal threaded hole 1046, thereby fixing the fixed plate 109, the integral plate 1044, and the protective plate 1041. After fixing, the handle 104 is protected by heat insulation through the protective plate 1041. During heat insulation, the heat is drawn to the side through the built-in guide plate 1042 inside the heat insulation groove 1047 and discharged to the outside through the heat exhaust hole 1045. This makes the protective plate 1041 and the heat insulation groove 1047 effectively insulate the outer surface of the main furnace body 101, so that the handle 104 is not easily heated when held after heating. At the same time, it is not easy to accidentally touch the surface and burn when gripping tightly. It is safe to grip and use effectively, and it is not easy to cause danger. This improves the convenience and safety of heat insulation protection of the handle 104 in the high-temperature test furnace main body 100 during high-temperature heating tests.
