Description

Technical Field

[0001] This utility model relates to the field of slitting technology, specifically to an aluminum pad slitting mechanism. Background Technology

[0002] An aluminum pad is a thin sheet-like mechanical component made of aluminum or aluminum alloy. It is mainly used for filling, supporting, isolating, sealing or protecting, compensating for dimensional deviations, absorbing vibration, preventing leakage or improving thermal / electrical conductivity during assembly.

[0003] In the process of producing aluminum pads, aluminum strips from aluminum coils are first guided under the punch head on a stamping machine. Then, the punch head is driven downward by a hydraulic cylinder. With each precise downward press of the punch head, aluminum pads of a predetermined shape will be continuously cut off from the aluminum strips. This kind of stamping machine that can cut out aluminum pads can be called an aluminum pad cutting mechanism.

[0004] However, existing aluminum pad slitting mechanisms generally use a single downward-moving stamping slitting head to slit the aluminum pad at a suspended position. Since the aluminum pad lacks support during suspended cutting, the aluminum pads on both sides of the cutting position may be pulled during the cutting process, resulting in burrs, tears, or dimensional deviations at the cut edge. This aluminum pad slitting mechanism has a poor slitting effect and does not meet the current requirements. Therefore, we propose an aluminum pad slitting mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum pad slitting mechanism to solve the problems mentioned in the background art. The existing aluminum pad slitting mechanisms generally use a single downward-moving stamping slitting head to slit the aluminum pad at a suspended position. Since the aluminum pad lacks support when slid-in, the aluminum pads on both sides of the cutting position may be pulled during the cutting process, resulting in burrs, tears, or dimensional deviations at the cut edge. The slitting effect of this aluminum pad slitting mechanism is poor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum pad slitting mechanism, comprising an aluminum pad slitting machine body, an inclined discharge port located at the middle of the upper end face of the aluminum pad slitting machine body, an inverted concave frame fixedly installed above the inclined discharge port on the upper end face of the aluminum pad slitting machine body, a slitting cylinder fixedly installed at the middle of the upper end face of the inverted concave frame, a lower pressure plate connected to the piston rod of the slitting cylinder, an L-shaped rod fixed on both sides of the outer surface of the lower pressure plate, a push block slidably installed inside the outer shell of the aluminum pad slitting machine body located below the L-shaped rod, and the surface of the push block facing the L-shaped rod being a first inclined surface;

[0007] A lifting plate is provided between the two pushing blocks, and the surfaces of the lifting plate facing the two pushing blocks are both second inclined surfaces;

[0008] A connecting rod is fixedly connected to the middle position of the upper surface of the lifting plate, and a second stamping and cutting head is fixedly installed on the upper end of the connecting rod. A discharge cylinder is fixedly installed on one side of the second stamping and cutting head and installed on the inner wall of the inclined discharge port.

[0009] Preferably, a metal rod is fixedly connected to both sides of the upper surface of the lifting plate, and a spring is sleeved on the outer surface of the metal rod. The upper and lower ends of the spring are respectively connected to the interior of the aluminum pad slitting machine body and the lower surface of the lifting plate.

[0010] Preferably, a first stamping and cutting head is fixedly installed at the middle position of the lower end face of the lower pressure plate, and the position of the first stamping and cutting head corresponds to the position of the second stamping and cutting head.

[0011] Preferably, one side of the inverted concave frame is provided with an aluminum strip guide mechanism fixedly installed on the outer surface of the aluminum pad slitting machine body, and an aluminum strip is provided on the inner side of the aluminum strip guide mechanism.

[0012] Preferably, a control button is fixedly installed on one side of the aluminum strip on the outer surface of the aluminum pad slitting machine body, and the slitting cylinder is electrically connected to the control button.

[0013] Preferably, the other end of the inclined discharge port extends to the rear end face of the aluminum pad slitting machine body, and the lower inner wall of the inclined discharge port is an inclined surface.

[0014] Preferably, a U-shaped cover plate is provided above the lifting plate on the upper end face of the aluminum pad slitting machine body, and the aluminum pad slitting machine body and the U-shaped cover plate are fixed together by screws.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. When the cutting cylinder drives the lower pressure plate downward and the first stamping cutting head fixed to the lower end face of the lower pressure plate for cutting, the second stamping cutting head located below the first stamping cutting head will be driven to move upward at the same speed as the first stamping cutting head. As the first stamping cutting head descends and the second stamping cutting head rises, the aluminum strip that has moved to the corresponding position on the upper and lower end faces below the first stamping cutting head will be cut simultaneously. The second stamping cutting head in the above technical solution can support the aluminum strip during the cutting process, thereby preventing the aluminum strip from deforming due to the downward movement of the first stamping cutting head, which would cause burrs, tears or dimensional deviations at the cut edge of the aluminum pad. This structure improves the cutting effect of the equipment.

[0017] 2. In this invention, when the downward-moving lower pressure plate drives the second stamping and slitting head upward, it will compress the spring indirectly connected to it. When the slitting process is completed, and the first stamping and slitting head is pulled upward by the slitting cylinder, the reaction force of the compressed spring can automatically push the second stamping and slitting head downward. With the above technical solution, there is no need to install any additional power source such as cylinder or motor to drive the second stamping and slitting head up and down, thereby reducing the operating cost of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The cutting cylinder 6 (model SC-32), aluminum strip 3 (model 1060) and spring 15 (model JX110) mentioned in this utility model can be obtained from the market or through private customization.

[0025] Please see Figures 1 to 4An embodiment of this utility model provides an aluminum pad slitting mechanism, including an aluminum pad slitting machine body 1. An inclined discharge port 4 is provided at the middle position of the upper end face of the aluminum pad slitting machine body 1. An inverted concave frame 5 is fixedly installed on the upper end face of the aluminum pad slitting machine body 1 above the inclined discharge port 4. A slitting cylinder 6 is fixedly installed at the middle position of the upper end face of the inverted concave frame 5. The piston rod of the slitting cylinder 6 is connected to a lower pressure plate 7. An L-shaped rod 9 is fixed on both sides of the outer surface of the lower pressure plate 7. A push block 10 is provided below the L-shaped rod 9 and is slidably installed inside the outer shell of the aluminum pad slitting machine body 1. The surface of the push block 10 facing the L-shaped rod 9 is a first inclined surface 11.

[0026] A lifting plate 12 is provided between the two pushing blocks 10, and the surfaces of the lifting plate 12 facing the two pushing blocks 10 are both the second inclined surfaces 13.

[0027] A connecting rod 16 is fixedly connected to the middle position of the upper end face of the lifting plate 12. A second stamping and slitting head 17 is fixedly installed on the upper end face of the connecting rod 16. A discharge cylinder 18 is fixedly installed on one side of the second stamping and slitting head 17 and is fixedly installed on the inner wall of the inclined discharge port 4. A first stamping and slitting head 8 is fixedly installed at the middle position of the lower end face of the lower pressure plate 7. The position of the first stamping and slitting head 8 corresponds to the position of the second stamping and slitting head 17. An aluminum strip guide mechanism 2 is fixedly installed on one side of the inverted concave frame 5 and is fixedly installed on the outer surface of the aluminum pad slitting machine body 1. An aluminum strip 3 is provided on the inner side of the aluminum strip guide mechanism 2. A control button is fixedly installed on one side of the aluminum strip 3 and is fixedly installed on the outer surface of the aluminum pad slitting machine body 1. The slitting cylinder 6 is electrically connected to the control button. The operation of the equipment can be controlled by the control button.

[0028] When the equipment is needed, the aluminum strip 3 is pushed along the aluminum strip guide mechanism 2. When the aluminum strip 3, which moves along the aluminum strip guide mechanism 2, moves between the first stamping slitting head 8 and the second stamping slitting head 17, the lower pressure plate 7 is pushed down by the slitting cylinder 6. As the lower pressure plate 7 descends, the first stamping slitting head 8, which is fixed to the lower end face of the lower pressure plate 7, will gradually move down together. As the first stamping slitting head 8 descends, the first stamping slitting head 8 will gradually approach the upper end face of the aluminum strip 3 located below it.

[0029] As the pressure plate 7 moves downward, the two L-shaped rods 9 fixed on both sides of its outer surface will move downward together. As the L-shaped rods 9 descend, the lower end face of the L-shaped rods 9 will contact the first inclined surface 11 on the outer surface of the push block 10. Under the action of the first inclined surface 11, as the L-shaped rods 9 descend, the push block 10 will be pushed towards the lifting plate 12. When the push block 10 moves towards the lifting plate 12, it will contact the second inclined surface 13 on the outer surface of the lifting plate 12. Under the action of the second inclined surface 13, as the push block 10 is continuously pushed by the L-shaped rods 9, the lifting plate 12 will gradually move upward. As the lifting plate 12 rises, the second stamping and cutting head 17 connected to it via the connecting rod 16 will also move upward together. As the second stamping and cutting head 17 rises, it will gradually approach the lower end face of the aluminum strip 3 located above it.

[0030] As the first stamping slitting head 8 and the second stamping slitting head 17 gradually approach the aluminum strip 3, the first stamping slitting head 8 and the second stamping slitting head 17 will respectively come into contact with the upper and lower end faces of the aluminum strip 3, and simultaneously perform cutting at the corresponding positions on the upper and lower end faces of the aluminum strip 3 to cut out aluminum pads.

[0031] The second stamping slitting head 17 in the above technical solution can support the aluminum strip 3 during the cutting process, thereby preventing the aluminum strip 3 from deforming due to the downward movement of the first stamping slitting head 8, which would cause burrs, tears or dimensional deviations at the cut edge of the aluminum pad. This structure improves the cutting effect of the equipment.

[0032] A metal rod 14 is fixedly connected to both sides of the upper end face of the lifting plate 12. A spring 15 is sleeved on the outer surface of the metal rod 14, and the upper and lower ends of the spring 15 are respectively connected to the interior of the aluminum pad slitting machine body 1 and the lower end face of the lifting plate 12. When the lifting plate 12 is pushed upward, it will squeeze the spring 15 connected to its upper end face. When the slitting operation is completed, the lower pressure plate 7 is pulled upward by the slitting cylinder 6. The reaction force of the squeezed spring 15 can gradually push the second punching slitting head 17 back to its original position.

[0033] The above technical solution eliminates the need for any additional power source, such as cylinders or motors, to drive the second stamping and slitting head 17 up and down, thereby reducing the operating cost of the equipment.

[0034] The other end of the inclined discharge port 4 extends to the rear end face of the aluminum pad slitting machine body 1, and the lower inner wall of the inclined discharge port 4 is an inclined surface. As the first stamping slitting head 8 and the second stamping slitting head 17 separate, the cut aluminum pads will move downwards together with the second stamping slitting head 17. When the second stamping slitting head 17 moves to the lowest point, the piston rod on the unloading cylinder 18 is pushed towards the aluminum pad located on the upper end face of the second stamping slitting head 17, so as to push the aluminum pad down and fall onto the inclined surface of the lower inner wall of the inclined discharge port 4. Then, under the action of gravity, the aluminum pad that has fallen onto the lower inner wall of the inclined discharge port 4 will be discharged from the inclined discharge port 4 located at the rear end face of the aluminum pad slitting machine body 1.

[0035] Above the lifting plate 12 is a U-shaped cover plate located on the upper end face of the aluminum pad slitting machine body 1, and the aluminum pad slitting machine body 1 and the U-shaped cover plate are fixed together by screws; the U-shaped cover plate can protect the internal structure of the aluminum pad slitting machine body 1, and when the internal structure of the aluminum pad slitting machine body 1 fails, the U-shaped cover plate can be removed to repair the internal structure of the aluminum pad slitting machine body 1.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
