Description

Technical Field

[0001] The utility model relates to the technical field of fin forming equipment, in particular to an electric heating fin plate compound die stamping forming device. Background Art

[0002] Finned heater is a common heating device that uses finned tubes as heating elements. Finned tubes are actually a layer of metal fins laid on the surface of the tube. The number and shape of the fins are different and can be designed according to the specific application scenario. Finned tubes heat air or liquid to a set temperature through electric heating or gas heating.

[0003] The working principle of the finned heater is similar to that of a traditional radiator. A heating coil is set inside the finned tube. When the current passes through the coil, the fins on the surface of the finned tube will emit heat. Through the fins on the surface of the finned tube, the heater can transfer heat to the surrounding air or liquid, thereby achieving the purpose of heating.

[0004] However, most of the existing fin forming equipment uses a movable die and a fixed punch to cooperate with each other to punch and cut the plate. After the punching and cutting are completed, the formed fins and waste are taken out manually. Although multiple fins can be punched and cut at one time, the demolding uses a manually assisted stop device, and then the formed fins and waste in the equipment are manually taken out. This method not only greatly reduces work efficiency, but also increases the risk of operation. Utility Model Content

[0038] See also Figures 1 to 6 In the embodiment of the utility model, a composite die stamping and forming device for an electric heating fin plate comprises an operating table 1 and a material placing box 2 arranged on the operating table 1, a lower die 3 is arranged inside the material placing box 2, and an upper die 4 is connected to the upper part of the lower die 3 through a stamping mechanism;

[0039] The operating table 1 is provided with a driving mechanism, which is connected to the punching mechanism. When the driving mechanism is running, the punching mechanism can drive the upper die 4 to move vertically back and forth, thereby cooperating with the lower die 3 to cut the plate;

[0040] A discharging assembly is also provided between the operating table 1 and the material box 2, and the discharging assembly is connected to the driving mechanism. After the upper mold 4 is separated from the lower mold 3, the discharging assembly will push out the cut sheet in the material box 2 under the action of the driving mechanism.

[0041] In the present solution, the driving mechanism is set up to alternately drive the stamping mechanism and the discharge assembly to operate. When the stamping mechanism cooperates with the driving mechanism, the upper mold 4 can move back and forth vertically, thereby cooperating with the lower mold 3 to cut the plate placed in the material box 2. During this process, the discharge assembly remains stationary. When the driving mechanism drives the discharge assembly to operate, the fins and waste materials punched and cut in the material box 2 can be pushed out together, making it easy for people to take them out, avoiding the risk of being cut by the upper mold 4 when reaching into the material box 2 to take it, thereby improving both processing efficiency and safety.

[0042] As a further solution of the utility model, the driving mechanism includes a first bracket 6 arranged on the operating table 1 and a rotating shaft 7 rotatably arranged on the first bracket 6;

[0043] The operating table 1 is provided with a motor 5 , one end of the rotating shaft 7 is connected to the output end of the motor 5 , and the outer wall of the rotating shaft 7 is further provided with a driving pulley 8 .

[0044] In this embodiment, since the rotating shaft 7 is rotatably arranged on the first bracket 6 and one end is connected to the output end of the motor 5, when the motor 5 is started, the output end of the motor 5 will drive the rotating shaft 7 to rotate, and at the same time, the driving pulley 8 will also rotate with the rotating shaft 7.

[0045] As a further solution of the utility model, the punching mechanism includes an L-shaped plate 9 arranged on the operating table 1 and a Y-shaped frame 10 arranged on the L-shaped plate 9, and a rotating rod 11 is rotatably arranged on the Y-shaped frame 10;

[0046] A driven pulley 12 is disposed at one end of the rotating rod 11 , and the driven pulley 12 is connected to the driving pulley 8 via a belt 13 .

[0047] In this embodiment, during the rotation of the driving pulley 8, the driving pulley 8 will drive the driven pulley 12 to rotate through the belt 13, and the rotating rod 11 will rotate following the driven pulley 12;

[0048] The L-shaped plate 9 is used for fixedly supporting the Y-shaped frame 10 and slidably supporting the lifting rod 16 , and the Y-shaped frame 10 is used for rotationally supporting the rotating rod 11 .

[0049] As a further solution of the utility model, a rotating disk 14 is provided at the other end of the rotating rod 11, and an eccentric column 15 is eccentrically provided on one side of the rotating disk 14;

[0050] A lifting rod 16 is vertically slidably provided on the L-shaped plate 9 , one end of the lifting rod 16 is connected to the top of the upper mold 4 , and the other end of the lifting rod 16 is movably connected to the eccentric column 15 through a connecting rod 17 .

[0051] In this embodiment, during the rotation of the rotating rod 11, the turntable 14 will follow the rotating rod 11 and drive the eccentric column 15 to rotate synchronously. Since one end of the lifting rod 16 is connected to the upper mold 4 and the other end is movably connected to the eccentric column 15 through the connecting rod 17, the rotating eccentric column 15 will cooperate with the connecting rod 17 and the lifting rod 16 to realize the vertical reciprocating movement of the upper mold 4. When the upper mold 4 moves downward, it will cooperate with the lower mold 3 to cut the plate.

[0052] As a further solution of the utility model, the discharging assembly includes a disc 18 and a limiting ring 19 and a sector plate 20 respectively arranged on one side wall of the disc 18, and the other side of the disc 18 is connected to the other end of the rotating shaft 7;

[0053] The outer wall of the sector plate 20 is composed of a curved surface 2001 and two straight surfaces 2002 .

[0054] In this embodiment, during the rotation of the shaft 7, the disc 18 will drive the limiting ring 19 and the sector plate 20 to rotate synchronously with the shaft 7, and the limiting ring 19 is used to limit the sliding column 24;

[0055] Since the outer wall of the sector plate 20 is respectively composed of a segment of arc surface 2001 and two segments of straight surfaces 2002, the switching between the horizontal reciprocating movement and the static state of the moving rod 22 can be realized.

[0056] As a further solution of the utility model, the operating table 1 is provided with a second bracket 21, a moving rod 22 is horizontally slidably provided on the second bracket 21, a connecting head 23 is provided at one end of the moving rod 22, and a sliding column 24 is rotatably provided on the connecting head 23;

[0057] One end of the sliding column 24 fits with one side of the disc 18, and the outer wall of the sliding column 24 fits with the inner wall of the limit ring 19 and the outer wall of the fan-shaped plate 20 respectively. The outer wall of the moving rod 22 is provided with a spring 25, and the two ends of the spring 25 are respectively against the second bracket 21 and the connecting head 23.

[0058] In this embodiment, if Figure 3 As shown, due to the existence of the spring 25 and the maintained compressed state, the moving rod 22, the connecting head 23 and the sliding column 24 always have a tendency to move to the right;

[0059] When the upper die 4 moves downward to cooperate with the lower die 3 to cut the plate, the slide post 24 will be in a state of being fitted and sliding with the arc surface 2001 of the sector plate 20. Due to the constant radius of the arc surface 2001 and the effect of the limit ring 19, the slide post 24 can only rotate but cannot move horizontally.

[0060] When the upper mold 4 starts to move upward, as the fan-shaped plate 20 rotates, one of the two straight surfaces 2002 fits against the slide post 24. During the fitting of one of the straight surfaces 2002 and the slide post 24, the slide post 24 will move to the right along one of the straight surfaces 2002 under the action of the spring 25; when the slide post 24 fits against the other straight surface 2002, the slide post 24 will be pushed horizontally to the left for reset movement until the slide post 24 fits against the curved surface 2001 and stops moving.

[0061] As a further solution of the utility model, a third bracket 26 is provided on the material box 2, and a push rod 27 is horizontally slidably matched on the third bracket 26, and a push plate 28 is provided at one end of the push rod 27, and an L-shaped rod 29 is provided at the other end of the push rod 27, and one end of the L-shaped rod 29 is connected to the other end of the moving rod 22;

[0062] The push plate 28 is located inside the material box 2 , and a avoidance groove 2801 adapted to the lower mold 3 is provided at the bottom end of the push plate 28 .

[0063] In this embodiment, during the horizontal rightward movement of the sliding column 24, the connecting head 23 and the moving rod 22 will move horizontally to the right together. Moreover, because the push rod 27 is slidably disposed on the third bracket 26 and one end is connected to the moving rod 22 through the L-shaped rod 29, the push rod 27 will move horizontally to the right following the moving rod 22.

[0064] When the push rod 27 moves horizontally to the right, it will drive the push plate 28 to push out the cut fins and waste materials in the material box 2 for a while, so as to facilitate people to take them out. The avoidance groove 2801 is used to adapt to the lower mold 3 so that the push plate 28 can push out the fins on the top of the lower mold 3.

[0065] When the slide column 24 moves horizontally to the left, the push plate 28 will be reset accordingly.
