Description

Technical Field

[0001] The invention relates to the technical field of tube expanders, and in particular to a feeding device and a vertical tube expander. Background Art

[0002] Vertical tube expanders are generally used to expand and flare heat exchangers. To facilitate loading, vertical tube expanders are usually provided with a loading device for flipping the heat exchanger from a horizontal state to a vertical state. The loading device includes a support frame hinged to the frame of the vertical tube expander and a motor for driving the support frame to rotate. The support frame is equipped with a plurality of support plates for fixing the heat exchanger. When the support frame rotates to a horizontal position, loading can be performed, the heat exchanger is horizontally fixed to the support plate, and then the support frame is rotated to a vertical position, and the heat exchanger is driven to rotate to a vertical state at the same time, so that the heat exchanger is located between the support plate and the frame. At this time, the heat exchanger can be fixed to the clamping mechanism of the frame to process the heat exchanger.

[0003] However, for a thicker heat exchanger, when the support frame drives the heat exchanger to rotate to a vertical position, the front surface of the heat exchanger is easily squeezed between the rack; for a thinner heat exchanger, when the support frame drives the heat exchanger to rotate to a vertical position, the distance between the front surface of the heat exchanger and the clamping mechanism of the rack will become larger, resulting in the inability of the clamping mechanism of the rack to firmly clamp the heat exchanger.

[0004] To this end, some manufacturers will set a screw nut mechanism between the support plate and the support frame to adjust the distance between the two. For heat exchangers of different thicknesses, the screw nut mechanism can be adjusted to adjust the distance between the support plate and the support frame, so that when the heat exchanger is moved to a vertical position, the distance between the heat exchanger and the clamping mechanism of the rack is moderate. However, this method requires the screw nut mechanism of each support plate to be adjusted separately during operation, which is inconvenient to operate and has low efficiency. Summary of the invention

To this end, the present invention provides a feeding device for a vertical tube expander, which can facilitate the feeding of a heat exchanger and improve the processing efficiency of the heat exchanger.

[0040] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0041] Reference Figures 1 to 4One embodiment of the present invention provides a feeding device, which is applied to a vertical tube expander. The feeding device includes a base 100, a rotating seat 110, a support frame 120, a first driving mechanism, and a second driving mechanism. The rotating seat 110 is rotatably mounted on the base 100. The support frame 120 is movably mounted on the rotating seat 110, and the support frame 120 is installed with at least two groups of first clamping assemblies. The first driving mechanism is mounted on the base 100 and is transmission-connected to the rotating seat 110. The first driving mechanism can drive the rotating seat 110 to rotate relative to the base 100. The second driving mechanism is mounted on the rotating seat 110 and is transmission-connected to the support frame 120. Among them, the rotating seat 110 can drive the support frame 120 to rotate relative to the base 100 and make the support frame 120 in a horizontal position or a vertical position. When the support frame 120 is in a vertical position, the second driving mechanism can drive the support frame 120 to reciprocate in the front-rear direction relative to the rotating seat 110.

[0042] In the above structure, the first driving mechanism can drive the rotating seat 110 to rotate relative to the base 100, and the rotating seat 110 can drive the support frame 120 to rotate relative to the base 100, and make the support frame 120 be located in a horizontal position or a vertical position. When the support frame 120 is located in a vertical position, the second driving mechanism can drive the support frame 120 to move relative to the rotating seat 110. When the feeding device is applied to a vertical tube expander, the feeding device is arranged on one side of the frame 200 of the vertical tube expander. When loading materials, first drive the support frame 120 to rotate through the rotating seat 110 and make the support frame 120 in a horizontal position. At this time, loading can be carried out, and the heat exchanger 300 to be processed is placed horizontally on the support frame 120, and the heat exchanger 300 is fixed by the first clamping assembly on the support frame 120; then drive the support frame 120 to rotate through the rotating seat 110 and make the support frame 120 in a vertical position, so that the heat exchanger 300 is in a vertical state. At this time, the support frame 120 can move relative to the rotating seat 110, and the second driving mechanism drives the support frame 120 to move relative to the rotating seat 110 in the front and rear direction close to or away from the frame 200, so that the heat exchanger 300 can be flexibly transported to the frame 200 of the vertical tube expanding machine.

[0043] In the process of conveying the heat exchanger 300 to the rack 200 of the vertical tube expander, in order to make the distance between the heat exchanger 300 and the rack 100 moderate, it is not necessary to individually adjust the distance between each group of first clamping components and the support frame 120. It is only necessary to drive the support frame 120 to move in the front-to-back direction relative to the rotating seat 110, so that all the first clamping components can be driven to move synchronously, thereby making the distance between the heat exchanger 300 and the rack 100 moderate, which is convenient for further processing of the heat exchanger 300. The whole process is simple and quick to operate, thereby improving the processing efficiency of the heat exchanger 300.

[0044] It is understandable that when the support frame 120 is just rotated to the vertical position, the support frame 120 can be located at the end of the rotating seat 110 away from the frame 200, thereby preventing the front surface of the heat exchanger 300 from being squeezed with the frame 200 of the tube expander when the support frame 120 drives the heat exchanger 300 to rotate to the vertical position. Then, the second driving mechanism drives the support frame 120 to move closer to the frame 200, so that the heat exchanger 300 can be flexibly transported to the frame 200 of the vertical tube expander, so that the heat exchanger 300 is located at a suitable position, which is convenient for the processing of the heat exchanger 300, improves the feeding efficiency of the heat exchanger, and thus can improve the processing efficiency of the heat exchanger 300.

[0045] It can be understood that the front surface of the heat exchanger 300 specifically refers to a side surface of the heat exchanger 300 that is away from the support frame 120 when the heat exchanger 300 is in a vertical state.

[0046] Reference Figures 1 to 9 In some embodiments, the second driving mechanism includes a second rotation driving device 114, a second screw rod 112, and a second nut 113. The second rotation driving device 114 is mounted on the rotating seat 110. The second screw rod 112 is mounted on the rotating seat 110 and is in driving connection with the second rotation driving device 114. The second nut 113 is threadedly connected to the second screw rod 112, and the support frame 120 is mounted on the second nut 113 and can follow the second nut 113 and move along the second screw rod 112.

[0047] In the above structure, the support frame 120 is mounted on the second nut 113. When the support frame 120 is in a vertical position, the second rotary drive device 114 can drive the second screw rod 112 to rotate relative to the rotating seat 110, so that the second nut 113 can drive the support frame 120 to move along the second screw rod 112. When the feeding device is applied to a vertical tube expander, the rotating seat 110 drives the support frame 120 to rotate and moves the support frame 120 from a horizontal position to a vertical position, thereby making the heat exchanger 300 on the support frame 120 in a vertical state. At this time, the second rotary drive device 114 drives the second screw rod 112 to rotate relative to the rotating seat 110, so that the second nut 113 can drive the support frame 120 to move closer to or away from the frame 200 along the second screw rod 112, and the support frame 120 can drive all the first clamping components to move synchronously, thereby making the distance between the heat exchanger 300 and the frame 100 moderate, which is convenient for further processing of the heat exchanger 300. The whole process is simple and quick to operate, thereby improving the processing efficiency of the heat exchanger 300.

[0048] It is understandable that the second rotation driving device 114 may specifically be a motor, a rotary cylinder or a rotary hydraulic cylinder, etc., and the present invention does not make any specific limitation on this.

[0049] It is understandable that the second driving mechanism can be a screw-nut mechanism including the second rotary driving device 114, the second screw 112 and the second nut 113. The second driving mechanism can also be an electric push rod, which is arranged on the rotating seat 110, and the output end of the electric push rod is connected to the support frame 120. When the support frame 120 is in a vertical position, the electric push rod can directly push the support frame 120 to move relative to the rotating seat 110. In addition, the second driving mechanism can also be a cylinder or a hydraulic cylinder, which is not specifically limited in the present invention.

[0050] It is understandable that, referring to Figures 1 to 9 In order to make the support frame 120 move more smoothly relative to the rotating seat 110, the rotating seat 110 is provided with a second slide rail 115, and the support frame 120 is movably mounted on the second slide rail 115 and can move along the second slide rail 115, so that the second driving mechanism can drive the support frame 120 to move along the second slide rail 115, so that the movement of the support frame 120 is smoother and more stable. Specifically, the support frame 120 can be movably mounted on the second slide rail 115 through a second slide seat 116.

[0051] Reference Figures 5 to 7 In some embodiments, the first driving mechanism includes a pushing part and a linkage rod 101. The pushing part is disposed on the base 100. The linkage rod 101 has a first end and a second end. The first end of the linkage rod 101 is rotatably connected to the rotating seat 110 and is located on one side of the rotating shaft 111 of the rotating seat 110. The second end of the linkage rod 101 is rotatably connected to the output end of the pushing part. The pushing part can drive the second end to move relative to the base 100 and make the first end drive the rotating seat 110 to rotate relative to the base 100.

[0052] In the above structure, by setting a pushing part and a connecting rod 101, the first end of the connecting rod 101 is rotatably connected to the rotating seat 110 and is located on one side of the rotating shaft 111 of the rotating seat 110, and the second end of the connecting rod 101 is rotatably connected to the pushing part. Therefore, the second end of the connecting rod 101 can drive the first end to push the rotating seat 110 to rotate around the rotating shaft 111 under the pushing action of the pushing part, so that the rotating seat 110 can drive the support frame 120 to rotate to a horizontal position or a vertical position.

[0053] It is understandable that, in addition to the structure in which the push part and the linkage rod 101 are connected, the first driving mechanism can also directly use a driving device such as a motor, a rotary cylinder or a rotary hydraulic cylinder to directly drive the rotating shaft 111 of the rotating seat 110 to rotate, and the present invention does not specifically limit this. It should be noted that if the first driving mechanism is connected to the rotating shaft 111 of the rotating seat 110 by transmission, and the rotating shaft 111 of the rotating seat 110 is directly driven to rotate, a large torque may be generated, and thus a high driving force output by the first driving mechanism is required. By setting the first driving mechanism as a structure in which the push part is connected to the linkage rod 101, it is possible to more conveniently drive the rotating seat 110 to rotate around the rotating shaft 111.

[0054] Reference Figures 5 to 7 In some embodiments, the pushing portion includes a first rotation driving device 104, a first screw rod 102, and a first nut 103. The first rotation driving device 104 is mounted on the base 100. The first screw rod 102 is mounted on the base 100 and is transmission-connected to the first rotation driving device 104. The first nut 103 is threadedly connected to the first screw rod 102, the first end is rotationally connected to the first nut 103, and the first end can follow the first nut 103 to move along the first screw rod 102.

[0055] In the above structure, the second end of the connecting rod 101 is rotatably connected to the second nut 113, and the first rotation drive device 104 can drive the first screw rod 102 to rotate relative to the base 100, so that the second nut 113 can drive the second end of the connecting rod 101 to move, and then drive the first end to push the rotating seat 110 to rotate around the rotating axis.

[0056] It is understandable that the first rotation driving device 104 may specifically be a motor, a rotary cylinder or a rotary hydraulic cylinder, etc., and the present invention does not make any specific limitation on this.

[0057] It is understandable that, referring to Figures 5 to 7 In order to protect the first rotation drive device 104, a protective cover can be provided on the outer periphery of the first rotation drive device 104, thereby preventing the support frame 120 from colliding with the second rotation drive device 114 when the support frame 120 is in a horizontal position, thereby protecting the first rotation drive device 104.

[0058] It is understandable that, in addition to the above structure, the push part can also directly adopt an electric push rod, which is arranged on the base 100, and the output end of the electric push rod is rotatably connected to the second end of the linkage rod 101. The electric push rod can directly push the second end of the linkage rod 101 to move and then push the first end to drive the rotating seat 110 to rotate relative to the base 100. In addition, the push part can also adopt a cylinder or a hydraulic cylinder, etc., which is not specifically limited by the present invention.

[0059] Reference Figures 5 to 7 In some embodiments, the base 100 is provided with a first slide rail 105 , the first nut 103 is connected to a first slide seat 106 movably mounted on the first slide rail 105 , and the second end is rotatably connected to the first slide seat 106 .

[0060] In the above structure, the second end of the linkage rod 101 is rotatably connected to the first slide 106, that is, the first slide 106 is rotatably connected to the first nut 103, and the first slide 106 can drive the second end of the linkage rod 101 to move following the first nut 103. The arrangement of the first slide rail 105 and the first slide 106 can make the movement of the second end of the linkage rod 101 smoother and more stable.

[0061] Reference Figures 1 to 9 In some embodiments, the base 100 is provided with two first buffer members 107 , and the rotating seat 110 can rotate relative to the base 100 and abut against the first buffer members 107 .

[0062] In the above structure, the rotating seat 110 can abut against the first buffer 107 during the rotation process relative to the base 100 , thereby preventing the rotating seat 110 from directly colliding with the base 100 , thereby protecting the rotating seat 110 and the base 100 .

[0063] It is understandable that the first buffer member 107 can be specifically configured as a flexible member, such as a silicone member, a rubber member, a polyurethane member, etc., and the present invention does not make any specific limitation on this.

[0064] It is understandable that the base 100 is provided with two first buffer members 107, which is only for Figures 1 to 9 The number of the first buffer members 107 may be two, one, three or more, which is not specifically limited in the present invention.

[0065] Reference Figures 1 to 9 In some embodiments, the rotating base 110 is provided with two second buffer members 117 , and the support frame 120 can move relative to the rotating base 110 and abut against the second buffer members 117 .

[0066] In the above structure, the support frame 120 can abut against the second buffer member 117 during the movement relative to the rotating base 110 , thereby preventing the support frame 120 from being separated from the rotating base 110 during the movement and protecting the support frame 120 .

[0067] It is understandable that the second buffer member 117 can be specifically configured as a silicone member, a rubber member, a polyurethane member, etc., and the present invention does not make any specific limitation on this.

[0068] It is understandable that the rotating seat 110 is provided with two second buffer members 117, which is only for Figures 1 to 9 The number of the second buffer members 117 may be two, one, three or more, which is not specifically limited in the present invention.

[0069] It should be noted that, refer to Figures 1 to 9 The base 100 is provided with a first buffer 107, and the rotating seat 110 is provided with a second buffer 117, thereby simultaneously protecting the rotating seat 110 and the support frame 120. Of course, the first buffer 107 may be provided only on the base 100, or the second buffer 117 may be provided only on the rotating seat 110, and the present invention does not specifically limit this.

[0070] In some embodiments, the feeding device further includes a detection device and a control system. The detection device is disposed on the rotating seat 110, and the detection device can detect the position of the support frame 120 on the rotating seat 110. The control system is electrically connected to the detection device and the second driving mechanism, and the control system can control whether the second driving mechanism works or not according to the information fed back by the detection device.

[0071] When the second driving mechanism drives the support frame 120 to move relative to the rotating seat 110, the detection device can detect the position of the support frame 120 on the rotating seat 110, and send the detected information to the control system. The control system analyzes the information fed back by the detection device. If it is determined that the support frame 120 moves to the preset position, the second driving mechanism is controlled to stop working, so that the moving seat stops moving. By setting up the detection device and the control system, when the feeding device is applied to the vertical tube expander, the control system can accurately control the stroke of the support frame 120 according to the information fed back by the detection device, and then can quickly and accurately transport the heat exchanger 300 to the appropriate position, so that the distance between the heat exchanger 300 and the frame 200 is moderate, and the entire operation is convenient and fast, thereby improving the processing efficiency of the heat exchanger 300.

[0072] It is understandable that the above detection device can be a distance sensor, such as an infrared distance sensor, an ultrasonic distance sensor, etc. In addition, the detection device can also be a proximity switch or other devices capable of detecting the position of the support frame 120 on the rotating base 110. The present invention does not specifically limit the specific type of the detection device.

[0073] Reference Figures 1 to 9 In some embodiments, each set of first clamping assemblies includes a support plate 121, a first clamping portion 122 and a second clamping portion 123, the support plate 121 is mounted on the support frame 120, the first clamping portion 122 and the second clamping portion 123 are mounted on the support plate 121 and can move closer or farther relative to each other.

[0074] In the above structure, at least two groups of first clamping assemblies are arranged on the support frame 120, and each group of first clamping assemblies includes a support plate 121, a first clamping portion 122 and a second clamping portion 123. When loading, the support plate 121 is driven to rotate by the rotating seat 110 and the support plate 121 is located in a horizontal position, the heat exchanger 300 is placed horizontally on the support plate 121, and the heat exchanger 300 is located between the first clamping portion 122 and the second clamping portion 123, the first clamping portion 122 and the second clamping portion 123 can move relatively close to or away from each other, and then the first clamping portion 122 and the second clamping portion 123 can cooperate to clamp the heat exchanger 300, so that the movement of the heat exchanger 300 is more stable.

[0075] It can be understood that the first clamping portion 122 and the second clamping portion 123 can move closer to or away from each other. Specifically, the support plate 121 may be provided with a fourth driving mechanism 124 that is transmission-connected to the first clamping portion 122, and the support plate 121 may also be provided with a fifth driving mechanism that is transmission-connected to the second clamping portion 123. The fourth driving mechanism 124 can drive the first clamping portion 122 to move closer to or away from the second clamping portion 123 relative to the support plate 121, and the fifth driving mechanism can drive the second clamping portion 123 to move closer to or away from the first clamping portion 122 relative to the support plate 121. Alternatively, the support plate 121 may be provided with a fourth driving mechanism 124 that is transmission-connected to the first clamping portion 122, and the second clamping portion 123 may be fixedly mounted on the support plate 121. The fourth driving mechanism 124 can drive the first clamping portion 122 to move closer to or away from the second clamping portion 123 relative to the support plate 121, so that the first clamping portion 122 and the second clamping portion 123 can cooperate to clamp the heat exchanger 300. In addition, the support plate 121 may be provided with a fifth driving mechanism that is transmission-connected to the second clamping portion 123, and the first clamping portion 122 may be fixedly mounted on the support plate 121. The fifth driving mechanism may drive the second clamping portion 123 to move relative to the support plate 121 closer to or away from the first clamping portion 122, thereby enabling the first clamping portion 122 and the second clamping portion 123 to cooperate in clamping the heat exchanger 300.

[0076] The fourth driving mechanism 124 may be an electric push rod, a pneumatic cylinder, a hydraulic cylinder, etc. Similarly, the fifth driving mechanism may be an electric push rod, a pneumatic cylinder, a hydraulic cylinder, etc., which is not specifically limited in the present invention.

[0077] Reference Fig.10 One embodiment of the present invention further provides a vertical tube expander, which includes a frame 200 and a loading device of any of the above embodiments. The loading device is located at the front side of the frame 200. When the support frame 120 is in a vertical position, the support frame 120 can move relative to the rotating base 110 in the front-to-back direction to approach or move away from the frame 200.

[0078] In the above structure, the loading device is located at the front side of the frame 200. When loading, the support frame 120 is first driven to rotate by the rotating seat 110 and the support frame 120 is placed in a horizontal position. At this time, loading can be carried out, and the heat exchanger 300 to be processed is placed horizontally on the support frame 120, and the heat exchanger is fixed by the first clamping assembly on the support frame 120; then the support frame 120 is driven to rotate by the rotating seat 110 and the support frame 120 is placed in a vertical position, so that the heat exchanger 300 is in a vertical state. At this time, the support frame 120 can move relative to the rotating seat 110, and the second driving mechanism drives the support frame 120 to move relative to the rotating seat 110 in the front and rear direction close to or away from the frame 200. The support frame 120 can drive all the first clamping assemblies to move synchronously, so that the distance between the heat exchanger 300 and the frame 100 is moderate, which is convenient for further processing of the heat exchanger 300. The whole process is simple and quick to operate, thereby improving the processing efficiency of the heat exchanger 300.

[0079] It is understandable that the above-mentioned feeding device is located at the front side of the frame 200, which is only for Fig.10 In order to enable the support frame 120 to move closer to or farther from the frame 200 in the front-to-back direction relative to the rotating seat 110 when the support frame 120 is in the vertical position, the loading device can also be arranged at the rear side of the frame 200. The present invention does not make any specific limitation to this.

[0080] Reference Fig.10 In some embodiments, the vertical tube expander further includes a rotating worktable 210 and a third driving mechanism. The rotating worktable 210 is rotatably mounted on the frame 200. The rotating worktable 210 is provided with four groups of second clamping assemblies 220 arranged at intervals along the circumference of the rotating worktable; the third driving mechanism is arranged on the frame 200 and is transmission-connected to the rotating worktable 210. The frame 200 is also provided with a tube expansion device, a flaring device and a feeding device. The feeding device, the tube expansion device, the flaring device and the feeding device are arranged in sequence around the rotating worktable 210. The third driving mechanism can drive the rotating worktable 210 to rotate relative to the frame 200 and make the four groups of second clamping assemblies 220 correspond one-to-one to the feeding device, the tube expansion device, the flaring device and the feeding device.

[0081] In the above structure, the heat exchanger 300 to be processed is first transported to a position close to the frame 200 through the loading device, and the heat exchanger 300 is clamped and fixed by the second clamping assembly 220 corresponding to the loading device, and the first clamping assembly on the support frame 120 is loosened, so that the heat exchanger 300 is fixed to the rotating worktable 210, and then the rotating worktable 210 is rotated and drives the heat exchanger 300 to rotate to the tube expansion device for tube expansion operation. After the tube expansion of the heat exchanger 300 is completed, the rotating worktable 210 is rotated again and drives the heat exchanger 300 to rotate to the expansion device for expansion operation. After expansion, the rotating worktable 210 is rotated again and drives the heat exchanger 300 to rotate to the unloading device, and the processed heat exchanger 300 is removed from the rotating worktable 210 through the unloading device. By setting up a rotating worktable 210, rotating the rotating worktable 210 can drive the heat exchanger 300 to move from the loading device to the tube expansion device, the flaring device and the unloading device. During this process, the loading device, the tube expansion device, the flaring device and the unloading device can work simultaneously, thereby improving the working efficiency of the tube expander.

[0082] It is understandable that the third driving mechanism may specifically be a motor, a rotary cylinder or a rotary hydraulic cylinder, etc., and the present invention does not make any specific limitation on this.

[0083] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
