Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fin processing, in particular to a structure for quickly adjusting the cutting deflection of air-conditioning fins. Background Art
[0002] After the air conditioner fins are formed in the progressive die, the material strip needs to be cut horizontally by the cutter assembly. During the cutting process, the local deflection of the material strip will increase, and the convexity or concavity will be serious, which cannot meet the requirement of keeping the material strip straight after cutting. For this reason, a pressing device is set on the progressive die and at the rear end of the cutter assembly. The flatness of the material strip is ensured by controlling the gap through which the material strip passes through the pressing device.
[0003] The existing press device gap adjustment is manually adjusted and observed by technicians based on experience, and then proofing is performed. It takes repeated adjustments to obtain the required flatness, which takes a long time, is inefficient, and cannot achieve high-precision adjustments. In order to save fin production costs and improve equipment utilization efficiency, a set of mold equipment often needs to produce fins with multiple material thicknesses and multiple flange heights. Manual adjustment is time-consuming and has low precision. As the fin thickness decreases below 0.1mm, facing higher precision requirements, the current press device can no longer meet the current production and processing needs. Utility Model Content
[0004] The utility model aims to provide a structure for quickly adjusting the cut-off deflection of air conditioner fins, so as to solve the problems of long time consumption and low precision of the existing deflection adjustment.
[0005] The utility model solves the technical problem by adopting a technical solution: an air conditioner fin cutting deflection quick adjustment structure, comprising an upper knife seat and a lower knife seat, the upper knife seat is connected to be provided with an upper deflection adjustment device, the lower knife seat is connected to be provided with a lower deflection adjustment device;
[0006] The upper deflection adjustment device comprises a pressure block fixing plate, a group of upper pressure blocks arranged side by side on the pressure block fixing plate, an upper pressure plate is fixedly arranged on the pressure block fixing plate, an upper adjusting screw for adjusting the height of the upper pressure plate is threadedly connected to the upper pressure plate, a rotating knob is arranged on the upper adjusting screw, a digital display device for reading the number of rotations is connected to the rotating knob, and the lower end of the upper adjusting screw is pressed on the upper tool seat; a locking device for locking the adjusting bolt is also arranged;
[0007] The lower deflection adjustment device includes a support fixing plate, a group of lower support blocks arranged side by side on the support fixing plate, a lower adjusting screw for adjusting the height of the lower supporting fixing plate is threadedly connected to the lower support fixing plate, the lower adjusting screw is rotatably mounted on the lower tool seat, a rotating handle is installed on the lower adjusting screw, and a digital display device for reading the number of rotations is also connected to the rotating handle.
[0008] Furthermore, the locking device includes a rotating shaft rotatably mounted on the upper knife seat, and a cam arranged on the rotating shaft, wherein the rotating cam acts between the upper knife seat and the upper pressure plate.
[0009] Furthermore, a limiting nut is arranged at the bottom of the upper adjusting screw rod, and a pressing arm which presses on the limiting nut is arranged on the rotating shaft.
[0010] The beneficial effects of the utility model are as follows: the utility model adjusts the deflection of the fins through the upper deflection adjustment device and the lower deflection adjustment device, so as to ensure that the fins maintain a certain flatness output after cutting. The upper deflection adjustment device is driven by the cam on the rotating shaft to separate the upper adjustment screw from the upper knife seat, so that the upper adjustment screw can be rotated, so that the upper pressure plate matched with the upper adjustment screw moves up and down, thereby driving the upper pressing block to move up and down to adjust the gap between the upper pressing block and the lower support block. At the same time, a digital display device is arranged on the upper adjustment screw and the lower adjustment screw to facilitate reading the number of rotations of the upper adjustment screw and the lower adjustment screw. The upper and lower moving distances of the upper pressing block and the lower support block can be obtained by calculation, so that the adjustment amount of the upper pressing block and the lower support block can be accurately controlled each time to meet the design requirements. The structure greatly improves the adjustment accuracy, has high adjustment efficiency and is convenient to adjust. The pressure arm on the rotating shaft ensures that the upper adjusting screw is clamped and positioned after being adjusted in place, so as to avoid the loosening of the upper adjusting screw during the operation of the mold, which affects the processing accuracy.

[0015] Examples, such as Figures 1 to 3As shown, a quick adjustment structure for the cutting deflection of air conditioner fins is arranged at the rear end of the progressive die for fin processing, where the fins are cut transversely, to ensure that the material strip maintains a certain degree of straightness during transverse cutting. The quick adjustment structure includes an upper knife seat 1 and a lower knife seat 2. The upper knife seat 1 is floatingly mounted on the lower die seat 7. Specifically, a group of ejection springs are arranged between the upper knife seat 1 and the lower die seat 7. The lower knife seat 2 is fixed on the lower die seat 7. A hitting rod 8 is arranged on the punch press, and a hitting block 9 for hitting the upper knife seat 1 is arranged on the hitting rod 8. The upper knife seat 1 moves downward under the action of the hitting block, driving the upper knife 11 on the upper knife seat 1 and the lower knife 21 on the lower knife seat 2 to cooperate to complete the cutting of the fins.
[0016] In order to prevent the fin from bending during transverse cutting and increasing the deflection to affect the operation of the subsequent process, the upper knife seat 1 is connected with an upper deflection adjustment device 3, and the lower knife seat 2 is connected with a lower deflection adjustment device 4, which are used to adjust the upward and downward convex amplitudes of the fins respectively.
[0017] The upper deflection adjustment device 3 includes a pressure block fixing plate 31, and a group of upper pressure blocks 32 arranged side by side on the pressure block fixing plate 31, and the upper pressure blocks 32 correspond to the fins one by one. An upper pressure plate 33 is fixedly arranged on the pressure block fixing plate 31, and the upper pressure plate 33 is threadedly connected with an upper adjustment screw 34 for adjusting the height of the upper pressure plate 33. In order to facilitate the rotation of the upper adjustment screw 34, a rotating knob 35 is arranged on the upper adjustment screw 34, and the upper adjustment screw 34 is driven to rotate by rotating the rotating knob 35, so that the upper pressure plate 33 threadedly matched with the upper adjustment screw 34 moves up and down, thereby driving the upper pressure block 32 to move up and down. The lower end of the upper adjustment screw 34 is pressed on the upper knife seat 1 to limit the height of the upper pressure block 32. In order to facilitate the precise control of the adjustment amount of the upper pressure block 32, a digital display device 5 for reading the number of rotations is connected to the rotating knob 35, and the adjusted height is displayed by calculation.
[0018] In order to facilitate the adjustment of the upper adjustment screw 34, a locking device 6 for locking the upper adjustment screw 34 is also provided. The locking device 6 includes a rotating shaft 61 rotatably mounted on the upper knife seat 1, and a cam 62 arranged on the rotating shaft 61, and the cam 62 acts between the upper knife seat 1 and the upper pressing plate 33. When it is necessary to rotate the upper adjustment screw 34 to adjust the upper pressing block 32, the rotating shaft 61 is rotated, and the cam 62 props up the upper pressing plate 33, so that the bottom of the upper adjustment screw 34 is separated from the upper knife seat 1, and the upper adjustment screw 34 can be rotated to adjust the position of the upper pressing plate 33 on the upper adjustment screw 34. After adjustment, the rotating shaft 61 is rotated to press the bottom of the upper adjustment screw 34 on the upper knife seat 1, and the height adjustment of the upper pressing block 32 is completed.
[0019] In order to facilitate locking the position of the adjusting bolt 34 after the position is determined and avoid up and down jumping, a limit nut 341 is set at the bottom of the upper adjusting screw 34, and a pressure arm 611 is set on the rotating shaft 61 to press on the limit nut 341. When the bottom of the upper adjusting screw 34 is pressed on the upper tool seat 1, the rotating shaft 61 is rotated to make the pressure arm 611 press on the limit nut 341 to complete the locking and fixing.
[0020] The lower deflection adjustment device 4 includes a lower tool holder 2, a group of lower support blocks 41 arranged side by side on the lower tool holder 2, a lower adjustment screw 43 for adjusting the height of the lower support block 41 is threadedly connected to the lower support block 41, the lower adjustment screw 43 is rotatably mounted on the lower tool holder 2, a rotating handle 44 is mounted on the lower adjustment screw 43, and a digital display device 5 for reading the number of rotations is also connected to the rotating handle 44. Its structural principle is the same as that of the upper deflection adjustment device 3.
