Description

Technical Field

[0001] This utility model relates to the field of flat tube technology for plate radiators, specifically a forming device for flat tubes of plate radiators. Background Technology

[0002] Flat-tube radiators offer a highly efficient heat dissipation solution. They utilize 52mm × 11mm × 1.5mm flat tubes as the basic modular unit for water passage. These tubes are stacked and welded together, with headers at both ends (35mm x 40mm) to form a single-panel flat-tube radiator. Flat-tube radiators come in four structural forms: single-panel, double-panel, single-panel with convection fins, and double-panel with convection fins. This design results in a smaller footprint and lighter weight, while also facilitating installation and maintenance. They possess excellent pressure resistance and are widely applicable to hot water heating systems in various buildings, such as hotels, office buildings, schools, and residences. Furthermore, their decorative properties make them suitable for locations where aesthetics and practicality are both important.

[0003] Existing flat tube forming devices for finned radiators do not position the workpiece during flattening, which can easily cause the workpiece to become skewed during flattening, thus affecting the forming quality. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a forming device for flat tubes of plate-type radiators.

[0005] The technical solution of this utility model is implemented as follows: A forming device for flat tubes of a plate radiator includes a base, a first sliding groove at one end of the base, a positioning mechanism on the base, a first movable seat slidably connected inside the first sliding groove on the base, the first movable seat being hinged to a first support plate, a positive and negative lead screw rotatably connected inside the base, a ring handle fixedly connected to one end of the positive and negative lead screw, the first support plate being hinged to a second support plate, the second support plate being hinged to a second movable seat, a spring fixedly connected to one end of the first movable seat, and a movable block fixedly connected to one end of the second movable seat.

[0006] Preferably, the second movable seat is slidably connected to the first sliding groove on the base, and the second movable seat is fixedly connected to the spring.

[0007] Preferably, the first support plate and the second support plate are inverted "V" shape.

[0008] Preferably, the width of the first groove on the base is equal to the sum of the widths of the first support plate and the second support plate.

[0009] Preferably, a round rod is fixedly connected inside the first groove on the base, and a second groove is provided at the bottom of the first groove on the base.

[0010] Preferably, the first and second movable seats are slidably connected to the round rod, the movable block is slidably connected to the second sliding groove on the base, and the positive and negative lead screws are rotatably connected to the movable block.

[0011] Preferably, a support frame is fixedly connected to one end of the base, a hydraulic cylinder is fixedly connected inside the support frame, and a pressure block is fixedly connected to one end of the hydraulic cylinder.

[0012] This utility model has the following beneficial effects:

[0013] 1. The forming device for the flat tube of this plate-type radiator involves placing the workpiece between two support plates. A hydraulic cylinder extends a downward pressing block to squeeze the workpiece, gradually flattening it and increasing its width. This pushes the second support plate, which in turn pushes the first support plate. The first support plate then pushes the first moving seat, gradually stretching the spring. The spring provides a counterforce, keeping the workpiece in the center of the base. This ensures the workpiece remains positioned during flattening, preventing it from tilting and thus maintaining the forming quality.

[0014] 2. The forming device for flat tubes of this plate radiator drives the positive and negative lead screws to rotate through the ring handle. The positive and negative lead screws drive the moving block and the second moving seat to move. The second moving seat pushes the first moving seat to move together through the spring. The second moving seat and the first moving seat drive the second support plate and the first support plate to move together. This makes it suitable for processing parts with different outer diameters, thereby improving the practicality of the forming device for flat tubes of this plate radiator.

[0022] like Figure 1-4 As shown, the forming device for flat tubes of plate radiators provided in this embodiment includes a base 1, a first sliding groove 2 at one end of the base 1, a positioning mechanism 3 on the base 1, a first movable seat 301 slidably connected inside the first sliding groove 2 on the base 1, the first movable seat 301 being hinged to a first support plate 302, a positive and negative lead screw 304 rotatably connected inside the base 1, a ring handle 303 fixedly connected to one end of the positive and negative lead screw 304, the first support plate 302 being hinged to a second support plate 306, the second support plate 306 being hinged to a second movable seat 305, a spring 307 fixedly connected to one end of the first movable seat 301, and a movable block 308 fixedly connected to one end of the second movable seat 305.

[0023] Furthermore, the second movable seat 305 is slidably connected to the first sliding groove 2 on the base 1, and the second movable seat 305 is fixedly connected to the spring 307.

[0024] By adopting the above technical solution, the first movable seat 301 can be pushed by the second movable seat 305 and the spring 307 to move together in the first sliding groove 2 on the base 1.

[0025] Furthermore, the first support plate 302 and the second support plate 306 are in an inverted "V" shape.

[0026] By adopting the above technical solution, the first support plate 302 and the second support plate 306 are in an inverted "V" shape, which can adapt to the processing of parts with different outer diameters.

[0027] Furthermore, the width of the first groove 2 on the base 1 is equal to the sum of the widths of the first support plate 302 and the second support plate 306.

[0028] By adopting the above technical solution, the first support plate 302 and the second support plate 306 can be fully inserted into the first groove 2 on the base 1 without hindering the forming of the workpiece.

[0029] Furthermore, a round rod 4 is fixedly connected inside the first groove 2 on the base 1, and a second groove 5 is provided at the bottom of the first groove 2 on the base 1.

[0030] Furthermore, the first movable seat 301 and the second movable seat 305 are slidably connected to the round rod 4, the movable block 308 is slidably connected to the second sliding groove 5 on the base 1, and the positive and negative lead screws 304 are rotatably connected to the movable block 308.

[0031] By adopting the above technical solution, the movement paths of the first movable seat 301 and the second movable seat 305 are restricted by the round rod 4 and the second sliding groove 5 on the base 1.

[0032] Furthermore, a support frame 6 is fixedly connected to one end of the base 1, a hydraulic cylinder 7 is fixedly connected inside the support frame 6, and a pressure block 8 is fixedly connected to one end of the hydraulic cylinder 7.

[0033] By adopting the above technical solution, the workpiece is flattened by driving the pressure block 8 through the hydraulic cylinder 7.

[0034] Working principle: Rotating the annular handle 303 will cause the lead screw 304 inside the base 1 to rotate. The lead screw 304 will cause the moving block 308 to slide in the second groove 5 on the base 1. The moving block 308 will cause the second moving seat 305 to slide in the first groove 2 on the base 1. The second moving seat 305 will push the first moving seat 301 to move together through the spring 307. At the same time, the second moving seat 305 and the first moving seat 301 slide on the round rod 4. At this time, the second moving seat 305... The seat 305 and the first movable seat 301 drive the second support plate 306 and the first support plate 302 to move together. Then, after the second support plate 306 moves to the appropriate position, stop rotating the annular handle 303. Place the workpiece between the second support plates 306. The workpiece will push the two second support plates 306, causing the second support plates 306 to rotate around the hinge point of the second movable seat 305 and the second support plate 306. The second support plate 306 will then push the first support plate 302. The support plate 302 pushes the first movable seat 301 to slide on the round rod 4. Simultaneously, the first movable seat 301 pulls open the spring 307. The reaction force of the spring 307 causes the first movable seat 301 and the first support plate 302 to support the second support plate 306. Thus, the workpiece is positioned on the base 1 by the positioning mechanism 3, placing it in the middle position of the base 1. Then, the hydraulic cylinder 7 on the support frame 6 is activated. The hydraulic cylinder 7 extends the pressure block 8 downwards, which presses the workpiece, completing the processing. As the workpiece is gradually flattened by the pressure block 8, the width of the workpiece will gradually increase, which will push the second support plate 306. The second support plate 306 will push the first support plate 302. The first support plate 302 will push the first moving seat 301 to gradually stretch the spring 307. The spring 307 will provide a reverse force so that the second support plate 306 keeps the workpiece in the middle position of the base 1. In this way, the positioning mechanism 3 still positions the workpiece during the flattening process, so that the workpiece remains in the middle position of the base 1.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
