Description

Technical Field

[0001] The utility model relates to the technical field of high-frequency heating, in particular to a continuous high-frequency heating device for a pipe body. Background Art

[0002] Conventional continuous high-frequency heating devices for pipes usually use high-frequency generators and induction heating coils to heat the pipes. However, due to the assembly line operation, the heating time for each pipe is long, resulting in low overall heating efficiency. Utility Model Content

[0003] The utility model aims at the technical problems existing in the prior art and provides a continuous high-frequency heating device for a tube body to solve the problem that the high-frequency heating time of each tube body is long due to assembly line operation, resulting in low overall heating efficiency.

[0004] The utility model solves the above technical problems with the following technical solutions: A continuous high-frequency heating device for a pipe, comprising:

[0005] Machine;

[0006] A high-frequency heater, which is arranged on one side of the machine and includes a high-frequency coil;

[0007] A preheating mechanism, the preheating mechanism comprising a heating block 1 having a heat generating function, wherein the heating block 1 is arranged on the axis of the high-frequency coil and fixed on the machine platform, a limiting groove is provided in the heating block 1, and the limiting groove is arc-shaped and coaxial with the high-frequency coil;

[0008] A tube body feeder, the tube body feeder comprises a feeder and a feeder box with a feeder opening near one side of the feeder, the feeder box is inclined to the top plane of the machine platform and is arranged on one side of the heating block 1, the feeder is arranged between the feeder box and the heating block 1, and is used to feed the tube body in the feeder box to the heating block 1 for preheating treatment;

[0009] The pusher assembly is arranged on one side of the heating block and is driven to move along the axis of the high-frequency coil.

[0010] The beneficial effects of the utility model are:

[0011] 1) When the feeder sends the tube in the feed box to the limiting groove of the heating block of the preheating mechanism, the tube can be heated in advance through the heat conversion effect of the heating block, so that the temperature of the tube is increased before it enters the high-frequency coil, so that in the subsequent heating process of the tube, the high-frequency coil only needs to consume a shorter time to heat the tube to the required temperature, thereby reducing the heating time of the high-frequency coil on the tube, greatly shortening the overall heating time.

[0012] 2) In summary, the device preheats the tube body in advance during the waiting time of the tube body, which can not only make full use of the waiting time, but also shorten the heating time of the tube body by the high-frequency coil by heating in advance, thereby improving the overall heating efficiency of the tube body.

[0013] On the basis of the above technical solution, the present invention can also be improved as follows.

[0014] Furthermore, the preheating mechanism also includes a heating block 2, a vertical rod, a fixed plate, and a cylinder 1. The vertical rod is fixed on the top plane of the machine, the fixed plate is fixed on the top of the vertical rod, the cylinder 1 is arranged on the fixed plate, and the driving end of the cylinder 1 passes through the bottom of the fixed plate along the radial direction of the limiting groove, and the heating block 2 is fixed on the penetrating driving end.

[0015] The beneficial effect of adopting the above further scheme is that the heating block 2 is driven by the cylinder 1 to move along the radial direction of the limit groove, so that the heating block 2 is suspended directly above the heating block 1, and then the position of the heating block 2 is further adjusted by controlling the cylinder 1 so that it contacts the top of the tube body placed in the limit groove, so that the heating block 2 can preheat the top of the tube body placed in the limit groove. Through the structure of this preheating mechanism, the top and bottom of the tube body can be fully preheated, thereby ensuring that the tube body has been evenly and fully preheated before entering the subsequent processing process, thereby improving the efficiency of heating the tube body.

[0016] Furthermore, the feeder includes a second cylinder, an opening, a baffle, a slide rail, a slider, and a building block. The opening is located between the first heating block and the discharge box and is opened on the top plane of the machine. The baffle is fixed on the side wall of the opening. The slide rail is fixed on one side of the baffle. The slider is slidably connected to the outer side of the slide rail. The building block is fixed on the top of the slider. The second cylinder is arranged on the machine, and the driving end of the second cylinder is connected to the slider.

[0017] Furthermore, a slope inclined toward a direction of the heating block is provided on the top of the building block.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that, through the design of the opening, baffle, slide rail, slider and building block, the smooth feeding of the tube body during the preheating process is achieved. Due to the inclined design of the discharge box, the tube body can slide freely into the opening, but is blocked by the baffle and can only stay on the building block. The slider is driven upward by cylinder 2. As the building block emerges from the opening, the tube body falls again into the limit groove of the heating block 1 due to the slope on the building block. At this moment, the heat of the heating block 1 can be fully transferred to the tube body, and the bottom of the tube body can be preheated, achieving a more comprehensive preheating effect.

[0019] Furthermore, the pushing assembly includes a cylinder three, a support, and a pushing plate. The support is located on one side of the heating block one and is fixed on the top plane of the machine. The cylinder three is fixed on the support. The pushing plate is coaxial with the limiting groove and fixed on the driving end of the cylinder.

[0020] The beneficial effect of adopting the above further scheme is that, due to the coaxial relationship between the push plate and the limit groove, cylinder three causes the push plate to displace along the axis of the limit groove. As the push plate moves, the push plate contacts the tube body on the limit groove and continues to push the tube body to move along the axis of the high-frequency coil until the tube body that has completed the preheating treatment enters the interior of the high-frequency coil for high-frequency heating treatment.

[0021] Furthermore, the outer diameter of the push plate is consistent with the inner diameter of the limiting groove.

[0022] The beneficial effect of adopting the above further scheme is that by having the push plate and the limiting groove have the same outer diameter size, it can be ensured that the push plate can completely fit the inner surface of the limiting groove, so that the push plate fits on the side of the tube body, and can effectively transmit thrust to the tube body, thereby pushing the tube body to move along the axial direction of the high-frequency coil.

[0023] Furthermore, an infrared temperature sensor is fixedly connected to the top of the push plate, and the infrared temperature sensor is fixed to the top of the push plate, and the axis of light emitted by the infrared temperature sensor passes through the axis of the limiting groove.

[0024] The beneficial effect of adopting the above further scheme is that by monitoring the temperature of the preheated tube body through the infrared temperature sensor, the preheating situation and effect of the tube body can be observed in real time. The infrared temperature sensor can measure the heat radiation on the surface of the tube body and provide the temperature data of the tube body by converting it into a temperature value. By observing the temperature data in real time, the operator can make adjustments as needed to ensure that the tube body is properly preheated, which helps to improve the processing quality and efficiency of the tube body.

DETAILED DESCRIPTION

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] Traditional continuous high-frequency heating devices for pipes usually use high-frequency generators and induction heating coils to heat the pipes. However, due to the assembly line operation, the heating time of each pipe is long, resulting in low overall heating efficiency. The utility model proposes a continuous high-frequency heating device for pipes to solve the above problem.

[0032] The utility model provides the following preferred embodiments

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, a continuous high-frequency heating device for a pipe body comprises:

[0034] Machine 100;

[0035] A high frequency heater, which is disposed on one side of the machine 100 and includes a high frequency coil 600;

[0036] The preheating mechanism 200 includes a heating block 210 for generating heat, wherein the heating block 210 is disposed on the axis of the high-frequency coil 600 and fixed on the machine 100, and a limiting groove 211 is provided in the heating block 210, and the limiting groove 211 is arc-shaped and coaxial with the high-frequency coil 600;

[0037] The tube feeder 300 includes a feeder 310 and a feeder box 320 with a feeder opening near one side of the feeder 310. The feeder box 320 is inclined to the top plane of the machine 100 and is arranged on one side of the heating block 210. The feeder 310 is arranged between the feeder box 320 and the heating block 210 to feed the tubes in the feeder box 320 to the heating block 210 for preheating.

[0038] The pusher assembly 400 is disposed on one side of the heating block and is driven to move along the axis of the high-frequency coil 600;

[0039] When the feeder 310 delivers the tube in the unloading box 320 to the limiting groove 211 of the heating block 210 of the preheating mechanism 200, the tube can be heated in advance through the heat conversion effect of the heating block 210, so that the temperature of the tube is increased before entering the high-frequency coil 600, so that in the subsequent heating process of the tube, the high-frequency coil 600 only needs to consume a shorter time to heat the tube to the required temperature, thereby reducing the heating time of the high-frequency coil 600 on the tube, greatly shortening the overall heating time;

[0040] In summary, the device preheats the tube body in advance during the waiting time of the tube body, which not only makes full use of the waiting time, but also shortens the heating time of the high-frequency coil 600 on the tube body by preheating, thereby improving the overall heating efficiency of the tube body.

[0041] The preheating mechanism 200 further includes a heating block 220, a vertical rod 230, a fixing plate 240, and a cylinder 1 250. The vertical rod 230 is fixed on the top plane of the machine platform 100, the fixing plate 240 is fixed on the top of the vertical rod 230, the cylinder 1 250 is arranged on the fixing plate 240, and the driving end of the cylinder 1 250 penetrates the bottom of the fixing plate 240 along the radial direction of the limiting groove 211, and the heating block 220 is fixed on the penetrating driving end;

[0042] The cylinder 1 250 drives the heating block 220 to move in the radial direction of the limiting groove 211, so that the heating block 220 is suspended above the heating block 1 210, and then the cylinder 1 250 is controlled to continue to adjust the position of the heating block 220 so that it contacts the top of the tube body placed in the limiting groove 211, so that the heating block 220 can preheat the top of the tube body placed in the limiting groove 211. Through the structure of the preheating mechanism 200, the top and bottom of the tube body can be fully preheated, thereby ensuring that the tube body has been evenly and fully preheated before entering the subsequent processing process, thereby improving the efficiency of heating the tube body.

[0043] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the feeder 310 includes a cylinder 2 311, an opening 312, a baffle 313, a slide rail 314, a slider 316, and a building block 315. The opening 312 is located between the heating block 210 and the unloading box 320 and is opened on the top plane of the machine 100. The baffle 313 is fixed on the side wall of the opening 312, the slide rail 314 is fixed on one side of the baffle 313, the slider 316 is slidably connected to the outer side of the slide rail 314, and the building block 315 is fixed on the top of the slider 316. The cylinder 2 311 is set on the machine 100, and the driving end of the cylinder 2 311 is connected to the slider 316. The top of the building block 315 is provided with a slope inclined toward the heating block 210.

[0044] Through the design of the opening 312, the baffle 313, the slide rail 314, the slider 316 and the building block 315, the smooth feeding of the tube body during the preheating process is achieved. Due to the inclined design of the discharge box 320, the tube body can slide freely into the opening 312, but is blocked by the baffle 313 and can only stay on the building block 315. The slider 316 is driven to slide upward by the cylinder 2 311. As the building block 315 is exposed from the opening 312, the tube body falls again into the limiting groove 211 of the heating block 1 210 due to the slope on the building block 315. At this moment, the heat of the heating block 1 210 can be fully transferred to the tube body, and the bottom of the tube body can be preheated, achieving a more comprehensive preheating effect.

[0045] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the push assembly 400 includes a cylinder 3 410, a support 420, and a push plate 430. The support 420 is located on one side of the heating block 1 210 and fixed on the top plane of the machine table 100. The cylinder 3 410 is fixed on the support 420. The push plate 430 is coaxial with the limiting groove 211 and fixed on the driving end of the cylinder.

[0046] Since the push plate 430 is coaxial with the limiting groove 211, the cylinder three 410 causes the push plate 430 to move along the axis of the limiting groove 211. As the push plate 430 moves, the push plate 430 contacts the tube body on the limiting groove 211 and continues to push the tube body to move along the axis direction of the high-frequency coil 600 until the tube body that has completed the preheating treatment enters the interior of the high-frequency coil 600 for high-frequency heating treatment.

[0047] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the outer diameter of the push plate 430 is consistent with the inner diameter of the limiting groove 211; by having the push plate 430 and the limiting groove 211 have the same outer diameter, it can be ensured that the push plate 430 can completely fit the inner surface of the limiting groove 211, so that the push plate 430 fits on the side of the tube body, and can effectively transmit thrust to the tube body, thereby pushing the tube body to move along the axial direction of the high-frequency coil 600.

[0048] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the top of the push plate 430 is fixedly connected with an infrared temperature sensor 500, and the infrared temperature sensor 500 is fixed on the top of the push plate 430, and the optical axis emitted by the infrared temperature sensor 500 passes through the axis of the limiting groove 211;

[0049] By monitoring the temperature of the preheated tube body through the infrared temperature sensor 500, the preheating situation and effect of the tube body can be observed in real time. The infrared temperature sensor 500 can measure the heat radiation on the surface of the tube body and provide the temperature data of the tube body by converting it into a temperature value. By observing the temperature data in real time, the operator can make adjustments as needed to ensure that the tube body is properly preheated, which helps to improve the processing quality and efficiency of the tube body.

[0050] The specific working process of the utility model is as follows:

[0051] (1) Cutting tube body

[0052] First, due to the inclined design of the discharge box 320, the tube body can slide freely into the opening 312, but is blocked by the baffle 313 and can only stay on the building block 315. The cylinder 2 311 is used to drive the slider 316 to slide upward. As the building block 315 is exposed from the opening 312, the tube body falls again into the limiting groove 211 of the heating block 1 210 due to the slope on the building block 315.

[0053] (2) Preheating the bottom of the tube

[0054] At this moment, the heat of the heating block 210 can be fully transferred to the tube body, and the bottom of the tube body can be preheated.

[0055] (3) Preheating the top of the tube

[0056] The cylinder 1 250 drives the heating block 220 to move in the radial direction of the limiting groove 211, so that the heating block 220 is suspended above the heating block 1 210. The cylinder 1 250 is then controlled to continue to adjust the position of the heating block 220 so that it contacts the top of the tube body placed in the limiting groove 211, so that the heating block 220 can preheat the top of the tube body placed in the limiting groove 211.

[0057] (4) High frequency heating

[0058] Since the push plate 430 is coaxial with the limiting groove 211, the cylinder three 410 causes the push plate 430 to move along the axis of the limiting groove 211. As the push plate 430 moves, the push plate 430 contacts the tube body on the limiting groove 211 and continues to push the tube body to move along the axis direction of the high-frequency coil 600 until the tube body that has completed the preheating treatment enters the interior of the high-frequency coil 600 for high-frequency heating treatment.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
