Abstract
Description
Technical Field
[0001] This utility model relates to the field of Bondi tube expander technology, and in particular to a fin pressing device for a Bondi tube expander. Background Technology
[0002] Current Bondi tube expanders use a single cylinder for fin clamping, which results in unstable fin clamping and affects the accuracy of tube insertion. This invention provides a double-cylinder clamping structure, which can improve fin clamping stability and thus improve product quality. Utility Model Content
[0003] The main objective of this invention is to provide a fin clamping device for a Bondi tube expander, so as to effectively solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a fin clamping device for a Bondi tube expander, comprising a platform, a flipping mechanism, a hook-head pressing plate mechanism, and a fin clamp; the fin clamp includes fin clamp A and fin clamp B, both of which are arranged parallel to each other on the platform, and two pressing blocks are respectively arranged on the upper side of fin clamp A and B, the pressing blocks being fixed to the lower side of a movable pressing plate, a flipping mechanism being arranged on the left side of the movable pressing plate, and a hook-head pressing plate mechanism being arranged on the right side.
[0005] Preferably, the flipping mechanism includes two auxiliary plates fixed on both sides of the movable pressure plate. The two auxiliary plates are rotatably fixed on a vertical plate by a fixed rotating shaft B. The vertical plate is fixed on the platform, and the lower end of the vertical plate passes through the platform. A left cylinder is fixed at the lower end of the vertical plate, and the head of the left cylinder push rod is rotatably fixed to the left end of the movable pressure plate by a pin.
[0006] Preferably, the hook pressure plate mechanism includes a fixed plate vertically fixed on the platform, and a "Z"-shaped hook pressure plate is rotatably fixed on the fixed plate by a fixed rotating shaft A. The rotating shaft A is located at the lower left corner of the "Z". The lower right end of the "Z"-shaped hook pressure plate is connected to the right cylinder push rod by a movable rotating shaft. The lower end of the right cylinder is rotatably fixed to the lower end of the fixed plate. The hook on the left side of the "Z"-shaped hook pressure plate presses against the right end of the movable pressure plate.
[0007] The beneficial effects of this utility model are: the "Z"-shaped hook pressure plate on the right side makes the fins more stable and facilitates the perforation of the copper tube. At the same time, the movable pressure plate can be opened to facilitate demolding. Attached Figure Description
[0008] Appendix Figure 1 This is a schematic diagram of the structure of the present invention when the fins are pressed together.
[0009] Appendix Figure 2 This is a schematic diagram of the structure of the movable pressure plate of this utility model when it is opened.
[0010] AppendixFigure 1 、 2 The right cylinder 1, the fixed plate 2, the platform 3, the moving pivot 4, the fixed pivot A 5, the hook head pressing plate 6, the movable pressing plate 7, the fin clamp A 8, the pressing block 9, the fixed pivot B 10, the auxiliary plate 11, the pin 12, the cylinder push rod 13, the left cylinder 14, the fin clamp B 15, the fin 16, and the vertical plate 17.
