Technical Field

[0001] The utility model relates to the technical field of pipeline heat treatment, and particularly relates to a heat treatment device for seamless carbon steel nominal pipes for high temperature use. Background Technique

[0002] At present, there are mainly two common cold processing methods for seamless carbon steel nominal pipes: one is the cold drawing process, and the other is the cold rolling process. The cold rolling process has relatively low production efficiency, but can greatly improve the density of the material, has good surface quality and high dimensional accuracy, and has been widely used in the processing of various high-precision and high-requirement seamless pipes. At the same time, the seamless carbon steel nominal pipe also needs to be heat treated after forming to make the seamless carbon steel nominal pipe reach the required hardness.

[0003] However, the existing heat treatment device for seamless carbon steel nominal pipes for high temperature use cannot adapt to seamless carbon steel nominal pipes of different lengths during use, and has poor practicability. Moreover, during heat treatment, the heating plate is in contact with air more, resulting in more heat loss and slower heating efficiency, which affects the processing efficiency.

[0004] Therefore, it is very necessary to invent a heat treatment device for seamless carbon steel nominal pipes for high temperature use to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a heat treatment device for seamless carbon steel nominal pipes for high temperature use to solve the problems put forward in the above background technique.

[0012] Preferably, a clamping groove is formed on one side of the mounting block close to the sliding block, and an inner support block is fixedly arranged in the middle of the bottom of the clamping groove, and one end of the inner support block extends to the outside of the clamping groove.

[0013] Preferably, locking knobs are installed on the front and back of the mounting block, extension rods adapted to the straight grooves are fixedly arranged at the top and bottom of one side of the base close to the sliding block, and limiting grooves adapted to the limiting blocks are formed on the front and back of the extension rods.

[0014] Preferably, a plurality of damping strips are fixedly arranged at the bottom of the base, and the plurality of damping strips are distributed at equal intervals.

[0015] The technical effects and advantages of the present utility model:

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides a heat treatment device for a seamless carbon steel nominal pipe for high temperature use as shown in Figures 1-5 Figure 8, which includes a heat treatment assembly 1, and clamping assemblies 2 are movably arranged on both sides of the heat treatment assembly 1.

[0025] Furthermore, the heat treatment assembly 1 includes a sliding block 101, and a fixing ring 102 is fixedly arranged at the top end of the sliding block 101. Ring-shaped flanges 103 are integrally formed at the openings on both sides of the fixing ring 102. Heat insulation layers 106 are adhesively arranged on the inner walls of the fixing ring 102 and the ring-shaped flanges 103. The heat insulation layer 106 is a heat insulation material. A connecting ring 104 is fixedly arranged in the middle of the inner side wall of the fixing ring 102, and a ring-shaped heating plate 105 is fixedly arranged on the inner side wall of the connecting ring 104. During heat treatment, due to the setting of the ring-shaped flange 103, the ring-shaped heating plate 105 is located inside the fixing ring 102, so that the ring-shaped heating plate 105 is not in contact with the outside air. At the same time, the setting of the heat insulation layer 106 further reduces heat dissipation, greatly improves the heating effect, improves the processing efficiency. A straight plate 107 is movably penetrated through the middle of one side of the sliding block 101. Straight grooves 108 are opened at the top and bottom ends on both sides of the straight plate 107. Limit blocks 109 are fixedly arranged at the ends of the front and back inner walls of the straight grooves 108 far from the sliding block 101.

[0026] The clamping assembly 2 includes a base 201, and a mounting block 202 is integrally formed at the top end of the base 201. A clamping groove 203 is opened on the side of the mounting block 202 close to the sliding block 101. An inner support block 204 is fixedly arranged in the middle of the bottom of the clamping groove 203, and one end of the inner support block 204 extends to the outside of the clamping groove 203. One end of the inner support block 204 is arranged in a frustum shape, which can facilitate the insertion of one end of the seamless carbon steel nominal pipe. Locking knobs 205 are installed on the front and back of the mounting block 202. Extension rods 206 adapted to the straight grooves 108 are fixedly arranged at the top and bottom ends on the side of the base 201 close to the sliding block 101. Through the movable arrangement between the two clamping assemblies 2 and the heat treatment assembly 1, the extension rods 206 can slide inside the straight grooves 108, so as to adjust the distance between the two clamping assemblies 2, and thus can fix seamless carbon steel nominal pipes of different lengths, with a wide application range and strong practicability.

[0027] Secondly, a plurality of damping strips 208 are fixedly arranged at the bottom end of the base 201, and the plurality of damping strips 208 are evenly spaced. The plurality of damping strips 208 can increase the friction between the base 201 and the ground and improve the stability of the clamping assembly 2. Limiting grooves 207 adapted to the limiting blocks 109 are formed in the front and back surfaces of the extension rod 206. Through the arrangement of the limiting blocks 109 and the limiting grooves 207, the extension rod 206 is prevented from sliding out of the inside of the straight groove 108.

[0028] Working principle of the present utility model:

[0029] During use, adjust the distance between the two clamping assemblies 2, move the clamping assemblies 2, and the extension rod 206 can slide inside the straight groove 108 until the distance between the two clamping assemblies 2 is greater than the length of the seamless carbon steel nominal pipe. Then, pass the seamless carbon steel nominal pipe through the fixing ring 102, with both ends exposed. Insert the two ends of the seamless carbon steel nominal pipe into the inside of the corresponding clamping slots 203 on the clamping assemblies 2 respectively. Then, tighten the seamless carbon steel nominal pipe through the locking knob 205. During the heat treatment, the sliding block 101 and the fixing ring 102 can slide on the straight plate 107 to process each position of the seamless carbon steel nominal pipe. During heating, due to the arrangement of the annular folded edge 103, the annular heating plate 105 is located inside the fixing ring 102, so that the annular heating plate 105 is not in contact with the outside air. At the same time, the arrangement of the heat insulation layer 106 further reduces the heat dissipation.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
