Description

Technical Field

[0001] The invention relates to the field of steel structure processing, and in particular to an intelligent heat treatment device for processing steel structure parts. Background Art

[0002] Quenching is the most widely used process method in the heat treatment of steel structural parts, and steel structural parts include many types, such as steel pipes. Due to special construction requirements, the inner wall of the steel pipe needs to be quenched to improve the strength and wear resistance of the inner wall of the steel pipe. For example, the Chinese patent with publication number: CN116356124A discloses a vertical quenching device for the inner wall of a steel pipe. By setting a compensation component, the device can ensure that the heating temperature of each part of the inner wall of the steel pipe is always consistent when heating the steel pipe, so that the quenching effect of the entire inner wall of the steel pipe is consistent, further improving the quenching effect of the device on the steel pipe and improving the accuracy of the device.

[0003] However, when quenching the inner wall of the steel pipe, since the steel pipe usually has a certain wall thickness, there is a difference in heat transfer efficiency between the inside and outside of the steel pipe during the process of the heating coil heating the inner wall of the steel pipe, which makes the temperature inside the steel pipe greater than the temperature outside the steel pipe, resulting in a large temperature difference between the inside and outside of the steel pipe, causing uneven temperature inside and outside the steel pipe and poor quenching effect. Summary of the invention

[0004] In order to overcome the disadvantage that during the process of heating the inner wall of the steel pipe by the heating coil, the temperature inside the steel pipe will be higher than the temperature outside the steel pipe, resulting in uneven temperature inside and outside the steel pipe and poor quenching effect, the present invention provides an intelligent heat treatment equipment for processing steel structural parts.

Since the scraper ring is made of rubber, the scraper ring can pass over the protrusions on the outer wall of the steel pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The fixing assembly includes a placement seat 1016, a clamping piece, a moving block 1019 and a pressure plate 1020; the fixing seat 1 is fixedly connected to the placement seat 1016; the mounting frame 2 is provided with two slide grooves 21; each slide groove 21 is slidably connected to a moving block 1019; the two moving blocks 1019 are commonly fixedly connected to a pressure plate 1020, and the pressure plate 1020 is slidably connected to the rope 1012, and a number of protrusions are provided on the pressure plate 1020; the placement seat 1016 is connected to a clamping piece for clamping the steel pipe 3, and the pressure plate 1020 is also connected to a clamping piece; the clamping piece is composed of a spring rod 1017 and a clamping ring 1018; the placement seat 1016 is fixedly connected to two annularly distributed spring rods 1017; the telescopic ends of all spring rods 1017 are commonly fixedly connected to a clamping ring 1018.

[0024] An inclined surface 1001 is provided on the inner side of the placement seat 1016 to guide the cooling water sprayed from the cooling ring 106 to the inner side of the steel pipe 3 for cooling to the drain pipe 11 to prevent impurities from accumulating on the inner side of the placement seat 1016 .

[0025] When in use, first connect the external water pump to the round pipe 102, then manually pass the steel pipe 3 to be quenched vertically through the two clamping rings 1018 through the external clamping device and place it on the placement seat 1016. The two clamping rings 1018 clamp and fix the bottom of the steel pipe 3. In the initial state, Figure 7As shown, then, the control motor 1010 is started, and the output shaft of the motor 1010 drives the shaft 1013 and the worm 1014 to rotate, and the worm 1014 drives the gear 1015 and the shaft 1013 to rotate, and then the shaft 1013 unwinds the rope 1012, so that the corresponding rope 1012 drives the connecting tube 101 and the connecting block 107 to move downward respectively, and after the heating coil 104 and the heating ring 108 penetrate into the steel pipe 3, the moving block 1019 is controlled to move the pressing plate 1020 downward until the clamping ring 1018 penetrates into the top of the steel pipe 3, and the protrusion on the pressing plate 1020 presses against the top of the steel pipe 3, so that the clamping ring 1018 clamps and fixes the top of the steel pipe 3. , the connecting tube 101 drives the parts thereon to move downward along the inner side of the steel pipe 3 under the action of its own gravity, and the connecting block 107 drives the heating ring 108 to move downward along the outer side of the steel pipe 3, until the heating coil 104 and the heating ring 108 are located at the bottom of the steel pipe 3, the cooling ring 106 and the heating ring 108 press the clamping ring 1018 downward, and the spring rod 1017 is compressed, so that the two clamping rings 1018 on the placement seat 1016 are temporarily separated from the fixation to the bottom of the steel pipe 3. At this time, since the top of the steel pipe 3 is fixed by the two clamping rings 1018 on the pressing plate 1020, the steel pipe 3 is in a stable state, so that the heating coil 104 and the heating ring 108 can heat the bottom of the steel pipe 3; Next, the heating coil 104 is energized to heat the inner wall of the steel pipe 3, and the heating ring 108 is energized to make the heating ring 108 perform compensatory heating on the outer side of the steel pipe 3, so that the temperature of the inner and outer sides of the steel pipe 3 are consistent, the temperature difference between the inner and outer sides of the steel pipe 3 is reduced, the temperature uniformity of the steel pipe 3 is improved, and the quenching effect is improved. At the same time, the output shaft of the control motor 1010 drives the rotating shaft 1013 and the worm 1014 to reverse, so that the rotating shaft 1013 reels the rope 1012. The corresponding ropes 1012 are used to respectively drive the connecting tube 101 and the connecting block 107 to move upwards. The connecting tube 101 drives the parts thereon to move upwards along the inner side of the steel pipe 3, while the connecting block 107 drives the heating ring 108 to move upwards along the outer side of the steel pipe 3. At the same time, the external water pump is controlled to start, and the cooling water is transported to the hollow connecting tube 101 through the circular tube 102. The cooling water in the connecting tube 101 is sprayed from the cooling ring 106 to the inner wall of the heated steel pipe 3 after passing through the connecting pipe 105, thereby quenching the inner wall of the steel pipe 3. After the cooling ring 106 and the heating ring 108 move up and detach from the clamping ring 1018 on the placement seat 1016, the clamping ring 1018 moves up under the elastic force of the spring rod 1017 to continue to clamp and fix the bottom of the steel pipe 3. The cooling water flowing down along the inner wall of the steel pipe 3 flows through the placement seat 1016 to the drain pipe 11 for collection. When the heating coil 104 and the heating ring 108 move to the top of the steel pipe 3, the cooling ring 106 and the heating ring 108 squeeze the clamping ring 1018 on the pressure plate 1020 upward, and the spring rod 1017 is compressed, so that the two clamping rings 1018 on the pressure plate 1020 are temporarily separated from the fixation on the top of the steel pipe 3. Since the bottom of the steel pipe 3 is fixed by the two clamping rings 1018 on the placement seat 1016 at this time, the steel pipe 3 is still in a stable state, so that the heating coil 104 and the heating ring 108 can heat the top of the steel pipe 3.

[0026] Example 2 On the basis of Example 1, Figure 5-6 As shown, a protective ring 201 is also included; all the connecting blocks 107 are fixedly connected with the protective ring 201 made of heat insulating material, and the protective ring 201 is fixedly connected to the heating ring 108. When the heating ring 108 heats the outside of the steel pipe 3, the heating ring 108 is protected and shielded by the protective ring 201 made of heat insulating material, thereby reducing the heat loss of the heating ring 108 and improving the heating efficiency.

[0027] It also includes a nozzle 2010; the two connecting blocks 107 are fixedly connected to a nozzle 2010.

[0028] It also includes a scraper ring 209; the two connecting blocks 107 are fixedly connected with the scraper ring 209, and a filter is arranged on the scraper ring 209, and the part where the scraper ring 209 contacts the steel pipe 3 is made of rubber material, and the scraper ring 209 is located below the nozzle 2010.

[0029] It also includes a suction ring 205 and a suction pipe 206 ; the connecting tube 101 is fixedly connected with a hollow suction ring 205 , and the suction ring 205 is fixedly connected to the connecting ring 103 ; the suction ring 205 is provided with a plurality of suction holes; and the suction ring 205 is connected with the suction pipe 206 .

[0030] It also includes a connecting plate 207 and a shielding ring 208; the connecting ring 103 is fixedly connected to a plurality of connecting plates 207; all the connecting plates 207 are commonly fixedly connected to the shielding ring 208, and the shielding ring 208 is a magnetic shielding material, and the shielding ring 208 is located above the heating coil 104, and the shielding ring 208 is in contact with the inner wall of the steel pipe 3. In order to avoid the excessive eddy current generated when the heating coil 104 performs induction heating on the inner wall of the steel pipe 3, causing heat to be concentrated on the surface of the steel pipe 3, causing local overheating and uneven heating of the steel pipe 3, therefore, part of the alternating magnetic field generated by the heating coil 104 is blocked by the shielding ring 208 from entering the steel pipe 3, thereby reducing the eddy current on the surface of the steel pipe 3.

[0031] The external air pump is connected to the suction pipe 206, and the external water pump is connected to the nozzle 2010. When the connecting tube 101 drives the heating coil 104 to move upward to heat the inner wall of the steel pipe 3, the inner wall of the steel pipe 3 will drop oxide scale under the action of high temperature. After the oxide scale falls on the heating coil 104, it affects the heating efficiency of the heating coil 104. Therefore, when the connecting tube 101 drives the heating coil 104 to move upward to heat the inner wall of the steel pipe 3, the cooling ring 106 moves upward along the inner wall of the steel pipe 3, and the high-pressure cooling water sprayed by the cooling ring 106 impacts the inner wall of the steel pipe 3, generating an impact force when cooling the inner wall of the steel pipe 3, so that the cleaning rod can flush the fallen oxide scale on the inner wall of the steel pipe 3 downward during the rising process, and the flushed oxide scale debris falls into the placement seat 1016 for collection.

[0032] At the same time, the external water pump is controlled to start and deliver cooling water to the nozzle 2010, and then the nozzle 2010 sprays cooling water to the outer wall of the steel pipe 3, so that the outer wall and the inner wall of the steel pipe 3 are evenly cooled, and when the rope 1012 drives the connecting block 107 and the parts thereon to move upward, the connecting block 107 drives the scraper ring 209 to move upward along the outer wall of the steel pipe 3, so that the scraper ring 209 scrapes off the oxide scale on the outer wall of the steel pipe 3, and the scraped oxide scale debris falls on the scraper ring 209 for temporary storage. Since the scraper ring 209 is made of rubber, the scraper ring 209 can pass over the protrusions on the outer wall of the steel pipe 3, and the nozzle 2010 first cools the outer wall of the steel pipe 3, and the scraper ring 209 scrapes the steel pipe 3. Therefore, the scraper ring 209 will not be affected by the high temperature of the steel pipe 3, and the cooling water sprayed by the nozzle 2010 to the outer wall of the steel pipe 3 flows through the filter on the scraper ring 209 to the placement seat 1016 for collection.

[0033] After the heating coil 104 heats the inner wall of the steel pipe 3, when the cooling ring 106 sprays cooling water onto the heated inner wall of the steel pipe 3, a large amount of gas will be generated. The gas gathers on the inner side of the steel pipe 3 and is not easy to disperse. Therefore, during the quenching process, the external air pump is controlled to start, and the suction ring 205 is sucked through the suction pipe 206, and then the gas inside the steel pipe 3 is sucked away through the suction hole on the suction ring 205.

[0034] Example 3 On the basis of Example 2, Figure 6 As shown, it also includes support balls 301 ; the placement seat 1016 is fixed with at least six annularly distributed support balls 301 , and the support balls 301 are located between the clamping rings 1018 .

[0035] When the steel pipe 3 is vertically placed between the two clamping rings 1018, the bottom of the steel pipe 3 contacts the support ball 301, and the bottom of the steel pipe 3 is supported by the support ball 301, thereby reducing the covering area of ​​the bottom of the steel pipe 3, improving the cooling and heat dissipation effect of the bottom of the steel pipe 3, and avoiding heat accumulation at the bottom of the steel pipe 3.

[0036] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above-mentioned embodiments, but should be determined not only by the appended claims, but also by the equivalents of the appended claims.
