Description

Technical Field

[0001] This utility model relates to the technical field of seamless steel pipe processing equipment, specifically a seamless steel pipe hot spinning temperature control device. Background Technology

[0002] Fire manifolds are pipelines that connect all parts of the fire extinguishing agent storage cylinder to the selector valve. They are mainly used to collect the fire extinguishing agents released from each fire extinguishing agent storage cylinder and transport them to the designated protected area. To ensure strength and aesthetics, existing fire manifolds are usually made of national standard thickened high-pressure seamless steel pipes. Seamless steel pipes are made by piercing a whole round steel bar and have no weld seams on the surface.

[0003] In the current seamless steel pipe processing, in order to enhance the strength and toughness of the seamless steel pipe and ensure its safety and stability in harsh environments, hot spinning is performed on the seamless steel pipe. During the hot spinning process, in order to ensure the plasticity and deformation of the material, control the oxidation and decarburization, and ensure the accuracy and stability of the spinning, thereby improving the quality and performance of the seamless steel pipe, it is necessary to control the heating temperature of the seamless steel pipe.

[0004] In existing seamless steel pipe processing, seamless steel pipes are usually heated and their temperature controlled using an induction heating furnace. However, during processing, due to the different sizes of seamless steel pipes produced according to actual needs, it is difficult to center the pipes when the pushing equipment pushes them into the induction heating furnace for heating, resulting in uneven heating. In order to achieve centered heating of seamless steel pipes of different sizes, a seamless steel pipe hot spinning temperature control device is now provided, which can eliminate the drawbacks of existing devices.

[0038] 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.

[0039] In one embodiment, such as Figures 1-3 As shown, a seamless steel pipe hot spinning temperature control device includes an induction heating furnace 1. One end of the induction heating furnace 1 is provided with a heating port 4, which extends to the outside of the other end of the induction heating furnace 1. An induction coil 3 is installed inside the heating port 4 in the induction heating furnace 1. The induction coil 3 is electrically connected to an external controller through a wire. The induction heating furnace 1 is provided with a clamping mechanism for clamping and rotating the seamless steel pipe.

[0040] The clamping mechanism includes two clamping plates 204 symmetrically arranged at one end of the induction heating furnace 1. The two clamping plates 204 are located at the upper and lower ends of the heating port 4, respectively. The two clamping plates 204 are provided with guide grooves 2011 at their close ends. Two sets of balls 205 are provided on each of the two clamping plates 204. The two sets of balls 205 are symmetrically arranged on the end face of the guide grooves 2011. The inner wall of the guide grooves 2011 is a symmetrical inclined plane.

[0041] In this embodiment, during use, the end of the seamless steel pipe to be hot-spun is moved to the port of the heating port 4 by the pushing device. Then, the port of the seamless steel pipe is inserted into the interior of the heating port 4. Then, the clamping mechanism allows the two clamping plates 204 to clamp the seamless steel pipes of different sizes. This allows for automatic clamping and centering of seamless steel pipes of different sizes, thereby enabling stable heating of seamless steel pipes of different sizes and avoiding uneven heating of the seamless steel pipes due to positional shift during the heating process.

[0042] Then, the induction coil 3 is activated by an external controller to heat the seamless steel pipe. At this time, the clamping mechanism can drive the seamless steel pipe to rotate through friction. The two sets of balls 205 can effectively reduce the friction between the seamless steel pipe and the guide groove 2011. After the seamless steel pipe is heated, it is pushed by a pushing device to move. At this time, the end of the seamless steel pipe can be moved to the outside of the other end of the induction heating furnace 1 through the heating port 4. Then, the seamless steel pipe can be hot-spinned by a corresponding hot spinning device. During this process, the temperature on the seamless steel pipe can be effectively maintained by the control of the induction coil 3 by the external controller, which can further improve the stability and processing efficiency of the seamless steel pipe.

[0043] In one embodiment, such as Figures 1-2 As shown, the clamping mechanism also includes a limiting component disposed on the induction heating furnace 1;

[0044] The limiting assembly includes: two limiting plates 202 symmetrically fixedly connected to one end of the induction heating furnace 1, the two limiting plates 202 being located on both sides of one end of the heating port 4, and two clamping plates 204 being slidably sleeved on the outer walls of the two limiting plates 202. The limiting assembly is used to limit the movement of the two clamping plates 204.

[0045] A lifting assembly is provided on a clamping plate 204;

[0046] In one embodiment, such as Figures 1-3 As shown, the lifting assembly includes: two limiting rods 2015 symmetrically fixedly connected inside a clamping plate 204; a lifting sleeve plate 2014 is slidably sleeved on the outer wall of each of the two limiting rods 2015; the lifting sleeve plate 2014 extends through to the outside of the end of the clamping plate 204 away from the induction heating furnace 1; the lifting sleeve plate 2014 and the clamping plate 204 are slidably connected up and down; a lifting seat 2016 is provided at the end of the clamping plate 204 away from the induction heating furnace 1; the lifting seat 2016 is fixedly connected to the lifting sleeve plate 2014.

[0047] A reset component is provided on the limit rod 2015;

[0048] The reset assembly is a spring 2017 sleeved on the outer wall of the limit rod 2015. One end of the spring 2017 contacts the outer wall of the lifting sleeve 2014, and the other end of the spring 2017 contacts the inner wall of a clamping plate 204.

[0049] The lifting platform 2016 is equipped with a rotating component;

[0050] The rotating assembly includes: a drive motor 2013 installed on the end of the lifting seat 2016 away from a clamping plate 204; a transmission rubber wheel 2012 is fixedly connected to the output end of the drive motor 2013; the transmission rubber wheel 2012 is rotatably connected to the lifting seat 2016 via a rotating shaft; through the cooperation of the lifting assembly, the reset assembly and the rotating assembly, seamless steel pipes of different sizes can be driven to rotate.

[0051] An adjustment component is provided on the induction heating furnace 1;

[0052] In one embodiment, such as Figures 1-2 As shown, the adjustment assembly includes: two bidirectional lead screws 2010 symmetrically arranged on the outside of the induction heating furnace 1; two lifting push plates 203 are symmetrically sleeved on the outer walls of the two bidirectional lead screws 2010; the two lifting push plates 203 are threadedly connected to the bidirectional lead screws 2010; the two lifting push plates 203 are respectively fixedly connected to two clamping plates 204; the upper and lower ends of the two bidirectional lead screws 201 are rotatably connected to support plates 201 through rotating shafts; the support plates 201 are fixedly connected to the induction heating furnace 1.

[0053] The induction heating furnace 1 is equipped with a drive assembly;

[0054] The drive assembly includes: a dual-axis motor 206 mounted on the top of the induction heating furnace 1 via a fixed base, and two transmission rods 207 symmetrically arranged on the outer side of the dual-axis motor 206, with the two transmission rods 207 respectively fixedly connected to the two output ends of the dual-axis motor 206;

[0055] A transmission assembly is provided on the transmission rod 207;

[0056] The transmission assembly includes: a first bevel gear 208 fixedly connected to the transmission rod 207 on the side away from the dual-axis motor 206; a second bevel gear 209 meshing with the outer wall of the first bevel gear 208; the second bevel gear 209 being located above the bidirectional lead screw 2010; and the second bevel gear 209 being fixedly connected to the bidirectional lead screw 2010 via a connecting shaft. Through the cooperation of the adjustment assembly, the drive assembly, and the transmission assembly, seamless steel pipes of different sizes can be clamped and centered using two clamping plates 204.

[0057] The above embodiments disclose a seamless steel pipe hot spinning temperature control device. It should be noted that the transmission rubber wheel 2012 is made of elastic material. Therefore, when the two clamping plates 204 clamp the seamless steel pipe, it will not have an adverse effect on the centering and locking of the seamless steel pipe.

[0058] In use, the end of the seamless steel pipe that needs to be hot-spun is moved to the port of heating port 4 by the pushing device, and then the port of the seamless steel pipe is inserted into the interior of heating port 4.

[0059] Then, the dual-axis motor 206 is started to drive the two transmission rods 207 to rotate synchronously. At this time, the first bevel gear 208, driven by the transmission rod 207, drives the second bevel gear 209 to rotate through meshing. At the same time, the bidirectional lead screw 2010, through the connecting shaft, drives the second bevel gear 209 to drive the lifting push plate 203 on the two clamping plates 204 to move closer to each other through the thread. At this time, the two clamping plates 204 slide along the outer wall of the limiting plate 202 under the drive of the lifting push plate 203. In this way, seamless steel pipes of different sizes can be clamped through the two clamping plates 204.

[0060] When the two clamping plates 204 come into contact with the outer wall of the seamless steel pipe through the ball bearings 205, during this process, the transmission rubber wheel 2012, blocked by the outer wall of the seamless steel pipe, pushes the two lifting sleeves 2014 to slide along the outer wall of the limit rod 2015 through the lifting seat 2016. At this time, the lifting sleeves 2014 are contracted by the displacement compression spring 2017. At the same time, the seamless steel pipe is clamped by the two clamping plates 204, which can automatically clamp and center seamless steel pipes of different sizes. This allows for stable heating of seamless steel pipes of different sizes and avoids uneven heating of the seamless steel pipe due to positional shift during the heating process.

[0061] Then, the induction coil 3 is activated by an external controller to heat the seamless steel pipe. At this time, the drive motor 2013 is started to drive the transmission rubber wheel 2012 to rotate. Simultaneously, the seamless steel pipe rotates under the friction of the transmission rubber wheel 2012. At the same time, the friction between the seamless steel pipe and the guide groove 2011 is effectively reduced by two sets of ball bearings 205. After the seamless steel pipe is heated, it is pushed by a pushing device to move. At this time, the end of the seamless steel pipe can be moved to the other end of the induction heating furnace 1 through the heating port 4. Then, the seamless steel pipe can be hot-spinned by a corresponding hot spinning device. During this process, the temperature on the seamless steel pipe can be effectively maintained by the control of the induction coil 3 by the external controller, thereby further improving the stability and processing efficiency of the seamless steel pipe.

[0062] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
