Description

Technical Field

[0001] This utility model belongs to the technical field of heating tube processing equipment, and in particular relates to a heating tube bending device. Background Technology

[0002] Heating tubes are made by inserting heating wires into a steel tube, filling the gaps with magnesium oxide powder (which has good thermal conductivity and insulation), and then shrinking the tube. They are then processed into various shapes required by the user. They are characterized by simple structure, high thermal efficiency, and good mechanical strength, and have good adaptability to harsh environments. They can be used for heating various liquids, acids, alkalis, and salts, and are also suitable for melting low-melting-point metals. They have advantages such as small size and high power.

[0003] Bending the heating tube is a crucial step in the production process. The bending operation requires fixing the heating tube, which necessitates opening and securing it with a clamp. After processing, the heating tube must be removed using the clamp again. These clamping procedures slow down the overall processing progress and affect the efficiency of the heating tube manufacturing process. Utility Model Content

[0036] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] like Figure 1-9 As shown, a heating tube bending device includes a processing table 101, a clamping device, a support member 102, a hydraulic cylinder 103, and a push block 105. A push plate 104 is provided on the piston rod of the hydraulic cylinder 103, and the push block 105 is connected to the push plate 104. The support member 102 is located on one side of the hydraulic cylinder 103, and the clamping device is located on one side of the support member 102. Specifically, the clamping device includes a clamping block 106 and a fixing block 107. The clamping block 106 is provided with a fixing groove 1061, and two sets of fixing blocks 107 are provided, respectively located on both sides of the fixing groove 1061. A second inclined groove is provided on the top of the fixing block 107, and the fixing block 107 is slidably connected to the fixing groove 1061. When the heating tube is placed in the fixing groove 1061, it pushes the fixing block 107 to move. After the heating tube is placed in the fixing groove 1061, the fixing block 107 is fixed.

[0038] More specifically, the clamping device also includes a first spring 111, a base plate 108 and a second spring. The fixing block 107 is connected to the inner wall of the fixing groove 1061 through the first spring 111, and the base plate 108 is connected to the bottom surface of the fixing groove 1061 through the second spring. When the base plate 108 moves to the bottom of the fixing groove 1061, the fixing block 107 is fixed.

[0039] Furthermore, the fixed block 107 is provided with an extension plate 119, and the extension plate 119 is provided with multiple movable plates 112. The movable plates 112 are slidably connected to the extension plate 119. The side wall of the fixed groove 1061 is provided with a through groove corresponding to the extension plate 119. A support plate 114 is slidably connected to the inner wall of the fixed groove 1061. When the support plate 114 moves towards the movable plate 112, it pushes the movable plate 112 to move. By setting multiple movable plates 112, the fixed block 107 can be supported by the support plate 114 no matter how far it moves. The fixed block 107 is fixed by the support plate 114, which can adapt to the processing of heating tubes of various diameters.

[0040] The movable plate 112 is provided with a first slider 120, and the extension plate 119 is provided with a plurality of first grooves for the first slider 120 to move. The inner wall of the first groove is provided with a protrusion 121, which is an arc-shaped structure and made of elastic material. The first slider 120 is provided with a groove 1201 corresponding to the protrusion 121, and the side wall of the groove 1201 is provided with a first inclined groove 1202. The protrusion 121 provides support for the movable plate 112, so that the movable plate 112 can only move when pushed by the support plate 114.

[0041] The extension plate 119 is provided with a first baffle 113, which is located at one end of the movable plate 112. The first baffle 113 is provided with a connecting rod 122, and the connecting rod 122 is provided with a second slider 123. The extension plate 119 is provided with a second sliding groove for the second slider 123 to move, and the second slider 123 is provided with a third spring 124. The groove 1201 and the first inclined groove 1202 make it easier for the movable plate 112 to return to its original position when the first baffle 113 pushes the movable plate 112 to move.

[0042] The support plate 114 is provided with a third slider 115, the inner wall of the fixing groove 1061 is provided with a third sliding groove for the third slider 115 to move, the third slider 115 is provided with a fourth spring 116, the third slider 115 is provided with a push rod 117, and the push rod 117 extends out from the third sliding groove.

[0043] The third slide groove has a movable groove on its side wall, and a stop bar 118 is provided in the movable groove. The stop bar 118 is connected to the base plate 108. The movable groove is located on one side of the third slider 115.

[0044] When fixing the heating tube, the heating tube is placed into the fixing groove 1061. Guided by the second inclined groove, the heating tube moves towards the bottom of the fixing groove 1061. The heating tube pushes the fixing block 107 to move to both sides of the fixing groove 1061. The fixing block 107 abuts against the side wall of the heating tube to fix it. When the heating tube moves to the bottom plate 108, it pushes the push plate 104 to move. The bottom plate 108 drives the stop rod 118 to move together, so that the stop rod 118 enters the movable groove. The fourth spring 116 pushes the third slider 115 to move in the third sliding groove. The support plate 114 moves towards the movable plate 112, pushing the movable plate 11 against the support plate 114. 2. The support plate 114 is moved so that it abuts against the movable plate 112, which is not moved, to provide support for the fixing block 107 and fix the fixing block 107, maintaining the fixing effect of the fixing block 107 on the heating tube, so that the heating tube can be bent. After the heating tube is processed, the push rod 117 is pushed to move, and the push rod 117 drives the support plate 114 to move back, so that the support plate 114 is reset. The third spring 124 pushes the second slider 123 to move, so that the first baffle 113 pushes the movable plate 112 to reset. The fixing block 107 is in a movable state, and the heating tube can be directly removed from the fixing groove 1061, so as to quickly complete the removal and placement of the heating tube.

[0045] Furthermore, the clamping block 106 has a fourth slider 126 at its bottom, and the processing table 101 has a fourth slide groove 125 for the fourth slider 126 to move. One end of the fourth slide groove 125 has a second baffle 109, and the second baffle 109 has a cover plate 110. The support member 102 has an annular groove 1021 to position the heating tube.

[0046] There is a distance between the clamping block 106 and the support member 102. That is, when the push block 105 pushes the heating tube to move, the heating tube drives the clamping block 106 to move towards the support member 102 until the heating tube enters the annular groove 1021. At this time, the clamping block 106 moves to the side of the second baffle 109, and the cover plate 110 covers the top of the fixing groove 1061. The push block 105 pushes the heating tube to perform the bending operation. The cover plate 110 is used to close the fixing groove 1061 to prevent the heating tube from coming out of the fixing groove 1061 in case of an accident, thereby improving the safety of heating tube processing.

[0047] The processing table 101 is also equipped with a heater to heat the heating tube so that the heating tube can be bent. This is a general configuration of bending equipment and will not be described in detail here.

[0048] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
