However, it will be understood by those skilled in the art that the driving device 3 is not limited to the present invention, and other devices for reciprocating the piston rod or the pulling shaft in a linear motion may be used.
The working principle of the jaw-type aluminum foil edge-pressing sealing device provided by the present invention is described in detail below.
In the initial state, the slider 26 is in the initial position, i.e., the roller 25 is in contact with the lower point of the inclined surface 261 of the slider 26. In this state, the elastic portion 27 is in an initial state, i.e., an unstressed state, so that the upper jaw 11 and the lower jaw 12 of the jaw-type aluminum foil binder sealing device are separated.
The method comprises the steps of placing a plurality of layers of aluminum foil fins to be sealed which are stacked in advance at fixed positions (in a tool), enabling a jaw 1 opened by the clamp type aluminum foil edge pressing sealing device to enter a position where a straight edge 1 to be sealed and a bent edge 2 to be sealed are overlapped, enabling the position where the straight edge 1 and the bent edge 2 of the aluminum foil are overlapped to be located between an upper clamp 11 and a lower clamp 12 of the opened jaw 1, keeping the aluminum foil in a horizontal state, and enabling the entering depth to be limited by a limiting part on the jaw 1.
Then, the manual (magnetic) valve 32 is pressed, and the cylinder rod 34 is extended forward in the X direction by the driving of the cylinder 33, thereby pushing the slider 26 to slide toward the jaw 1. As shown in fig. 8, since the surface of the slider in contact with the roller 25 is the inclined surface 261, the thrust F1 given to the roller 25 by the sliding of the slider 26 is a force perpendicular to the tangent line of the contact point of the inclined surface 261 and the roller 25. The thrust force F1 can be decomposed into a thrust force Fx in the X direction and a thrust force Fz in the Z direction. Therefore, the roller 25 advances in the direction of the jaw 1 under the influence of the X-direction thrust Fx, and climbs to the high point of the inclined surface 261 of the slider 26 under the influence of the Z-direction thrust Fz. Since the slider 26 moves upward (Z direction) along the inclined surface 261, the first sub-drive arm 224 and the second sub-drive arm 225 are also moved upward. However, the driving arm 221 of the movable clamp plate 22 is connected to the wing portion 214 via the first pin 23, so that the movable clamp plate 22 can only rotate around the first pin 23. Therefore, the upper top portion 222 of the movable clamping plate 22 moves downward under the driving of the driving arm 221, and the elastic portion 27 is in a compressed state. The upper top 222 drives the upper jaw 11 to move downwards, so that the upper jaw 11 and the lower jaw 12 are closed, and the aluminum foil placed in the jaw 1 is squeezed, thereby forming the effect of occlusion and edge sealing as shown in fig. 7. And (4) performing edge pressing and sealing on all the layers of aluminum foil fins to obtain the core body of the countercurrent plate type heat exchanger. The aluminum foil fins after edge pressing and sealing are integrated in one plane, and the sealing consistency is good.
After the sealing of the aluminum foil fins is completed, the cylinder piston rod 34 is retracted backward, and the slider 26 is driven to slide backward in the X direction and return to the initial position. At this time, the roller 25 slides down the inclined surface 261, returns to the low point of the inclined surface 261, and carries the first sub-driving arm 224 and the second sub-driving arm 225 downward. Since the movable clamping plate 22 rotates around the first pin 23, the first sub-driving arm 224 and the second sub-driving arm 225 move downward, and drive the upper top portion 222 to move upward, at this time, the elastic portion 27 releases the elastic force and recovers to its original shape, and the upper top portion 222 drives the upper jaw 11 to move upward, so that the upper jaw 11 and the lower jaw 12 open.
To sum up, the utility model provides a jaw type aluminium foil blank pressing sealing device has following technological effect: (1) The upper clamp and the lower clamp extend along the Y direction through design, and the thickness in the Z direction is smaller than the gap between the upper layer and the lower layer of the aluminum foil fin, so that the edge pressing sealing of the aluminum foil fin can be performed in the narrow gap with the edge interval of two adjacent layers of the aluminum foil fins being 2.1mm. (2) The shape after edge pressing and sealing is a 'micro great wall' shape, and the sealing strength is improved. (3) The length of the jaw in the Y direction is larger than or equal to the length of the edge of the aluminum foil fin, so that the edge pressing can be performed at one time, the middle part does not need to be connected, no break point exists, and the sealing effect is good. (4) Simple structure, easy to operate can improve work efficiency, reduces artifical intensity of labour, uses manpower sparingly resources.
The above has described the clamp-type aluminum foil edge-pressing sealing device provided by the present invention in detail. Any obvious modifications thereof, which would be obvious to a person of ordinary skill in the art, without departing from the essential teachings of the invention, would constitute a violation of the patent rights of the invention and would bear corresponding legal obligations.
