Description

Technical Field

[0001] The utility model belongs to the technical field of punching devices, and particularly relates to an automatic punching device for aluminum profiles. Background Art

[0002] During the use of aluminum profiles, punching is required, and usually a punching device is needed for cooperation. Generally, the existing punching devices include a positioning die and a punching die. Usually, the aluminum profile is manually placed on the positioning die, and then the punching die is controlled by an oil cylinder to punch the aluminum profile. The existing punching devices often do not have a pressing device, and generally the aluminum profile is manually placed on the positioning die; after long-term work, the positions of the aluminum profile and the positioning die are prone to deviation, resulting in errors in the positions where the aluminum profile needs to be punched; at the same time, the punching force directly applied to the aluminum profile by the oil cylinder is relatively large, and the punching effect is poor. Secondly, the overall processing efficiency is relatively low by manual feeding by the operator. Therefore, it is necessary to design an automatic punching device for aluminum profiles to overcome the above difficulties. Summary of the Invention

[0003] Aiming at the problems existing in the prior art, the utility model designs an automatic punching device for aluminum profiles. The utility model sets a crimping component in the frame main body to fix the aluminum profile, accurately controls the punching force through the punching component, and has a good punching effect; at the same time, the automatic loading and unloading of the aluminum profile is completed through the punching feeding line and the material transfer component, greatly improving the overall processing efficiency.

[0004] The invention purpose of the utility model is realized through the following technical solutions: an automatic punching device for aluminum profiles, including a frame main body, a punching feeding line is arranged at the feeding end of the frame main body, and an alignment component is arranged at the end of the punching feeding line; a pressing component for pressing the aluminum profile is arranged on the frame main body, and a punching component for punching is arranged on the side of the pressing component; the punching component includes a punching die and an oil cylinder, and the oil cylinder works to control the punching die to move towards the aluminum profile on the pressing component; a material transfer component for synchronous loading and unloading is arranged directly above the pressing component and the punching component, and the material transfer component includes two pairs of clamping jaw cylinders arranged in pairs.

[0005] Preferably, the punching feeding line includes a conveyor belt capable of moving relative to the frame main body, and a plurality of blocking parts for separating aluminum profiles are arranged on the conveyor belt; the alignment component is arranged at the end of the conveyor belt close to the frame main body. By arranging the blocking parts, the aluminum profiles can be separated orderly, facilitating the accurate grasping of the aluminum profiles by the material transfer component.

[0006] Preferably, the alignment assembly includes a positioning base that can slide relative to the main body of the frame. A first track for installing the positioning base is provided on the main body of the frame. A fastener for locking the two is provided between the positioning base and the main body of the frame. A horizontal cylinder is arranged on the upper end surface of the positioning base, and a vertical cylinder is arranged on the side wall of the positioning base. A limiting support base is arranged on the piston rod of the vertical cylinder. The horizontal cylinder is arranged towards the aluminum profile on the conveyor belt. A push plate is arranged on the piston rod of the horizontal cylinder, and the push plate and the end of the aluminum profile are arranged perpendicular to each other.

[0007] When the aluminum profile is transported to the alignment assembly by the conveyor belt, the horizontal cylinder controls the push plate to approach the aluminum profile, so as to align the aluminum profile left and right. In this way, when the aluminum profile is transported to the pressing assembly by the material transfer assembly, there is no need to re-align it. When the aluminum profile is placed down, it can just be directly placed on the positioning mold of the pressing assembly. Then the vertical cylinder works to control the aluminum profile to lift, so that the aluminum profile can be separated from the conveyor belt. When the aluminum profile is transported away by the material transfer assembly, the alignment assembly repeats the above steps, and then the material transfer assembly can continuously grab the aluminum profile in sequence.

[0008] Preferably, the pressing assembly includes a positioning mold, a pressing shield, a first cylinder and a pressing rotating shaft. The positioning mold and the pressing shield are fixedly installed on the main body of the frame. The pressing rotating shaft is installed between the main body of the frame and the pressing shield through bearings. The end of the pressing rotating shaft extends towards the inside of the pressing shield, and a gear that rotates synchronously with it is arranged at the end of the pressing rotating shaft. A rack that can expand and contract relative to it is arranged inside the pressing shield, and the rack and the gear mesh with each other. A first cylinder fixedly connected to it is arranged on the pressing shield, and the piston shaft of the first cylinder is fixedly connected to the rack. When the first cylinder drives the rack to expand and contract, the gear drives the pressing rotating shaft to rotate. A pressing piece fixedly connected to it is arranged on the pressing rotating shaft, and the pressing rotating shaft drives the pressing piece to rotate towards the aluminum profile on the positioning mold.

[0009] When the first cylinder works, it drives the rack to expand and contract. When the rack expands and contracts, it drives the gear to rotate. When the gear rotates, it drives the pressing rotating shaft to rotate. When the pressing rotating shaft rotates, it drives the pressing piece to squeeze and contact the aluminum profile on the positioning mold, so as to fix the aluminum profile. In this way, the position where the aluminum profile needs to be punched can be aligned with the punching assembly, and the punching effect is better.

[0010] Preferably, the pressing rotating shaft is a multi-sided prism-shaped shaft, and the pressing piece is sleeved and fixedly connected to the pressing rotating shaft. A number of rolling pieces that can rotate relative to it are arranged inside the pressing shield. A follower sliding plate fixedly connected to it is arranged on the rack. The follower sliding plate is stuck on the rolling pieces, and the end of the rack facing away from the follower sliding plate meshes with the gear.

[0011] Through the mutual cooperation of the rolling member and the follower skateboard, the path of the rack's telescoping remains fixed, the meshing effect between the rack and the gear is better, and the process of the gear driving the pressing rotating shaft to rotate is more stable and reliable.

[0012] Preferably, the punching assembly further includes a punching movable side plate, a guiding track, and a strip-shaped push rod; the main body of the rack is provided with a guiding track perpendicular to the pressing assembly, the guiding track is provided with a punching movable side plate, and a punching die fixedly connected thereto is arranged on the punching movable side plate; a strip-shaped push rod hinged to the punching movable side plate is arranged on the punching movable side plate, and an oil cylinder connecting the two is arranged between the end of the strip-shaped push rod and the main body of the rack; the cylinder body of the oil cylinder is hinged to the main body of the rack, and the piston rod of the oil cylinder is hinged to the strip-shaped push rod; when the oil cylinder drives the strip-shaped push rod to move, the strip-shaped push rod drives the punching movable side plate to move along the guiding track.

[0013] When the oil cylinder works, it drives the strip-shaped push rod to move. When the strip-shaped push rod moves, it drives the punching movable side plate to move along the guiding track. When the punching movable side plate moves, it drives the punching die to punch the aluminum profile on the positioning die. Here, the oil cylinder and the strip-shaped push rod drive the punching movable side plate to move, and when the punching movable side plate moves along the guiding track, the punching force of the punching die is more uniform and the punching effect is better.

[0014] Preferably, the oil cylinder and the strip-shaped push rod are both arranged in pairs, and the two strip-shaped push rods are respectively arranged on both sides of the punching movable side plate; the punching dies are arranged in pairs and are vertically oriented towards the positioning die; a strip-shaped through hole for blanking is arranged on the main body of the rack, and the strip-shaped through hole is arranged directly below the positioning die and the punching die; a pair of waste recycling grooves are arranged on the lower end surface of the main body of the rack, and the feeding end of the waste recycling groove is oriented towards the strip-shaped through hole.

[0015] The punching dies, the oil cylinder, and the strip-shaped push rod are arranged in pairs, which facilitates punching both ends of the aluminum profile simultaneously. The punching waste is recycled through the waste recycling groove to prevent the waste from remaining in the aluminum profile.

[0016] Preferably, the material transfer assembly includes a material transfer base, a rotating motor, a track plate, a horizontal moving plate, and a vertical frame; the material transfer base is fixedly installed on the top of the main frame body, and the rotating motor and the track plate are respectively arranged at both ends of the material transfer base; a horizontal moving plate capable of horizontally moving relative to the material transfer base is arranged on the material transfer base, and a vertical frame capable of vertically moving relative to the horizontal moving plate is arranged on the horizontal moving plate; a first connecting rod capable of rotating relative to the track plate is arranged on the track plate, and the first connecting rod is connected to the motor shaft of the rotating motor; the end of the first connecting rod away from the rotating motor is slidably connected to the vertical frame, and a rolling bearing is arranged on the vertical frame, and the rolling bearing passes through the first connecting rod and is stuck in the path of the track plate; when the rotating motor drives the first connecting rod to rotate, the vertical frame moves along the path of the track plate; a pair of strip plates are arranged at the bottom of the vertical frame, and clamping jaw cylinders are respectively arranged at both ends of the strip plates; a support assembly for placing aluminum profiles is arranged at the discharge end of the main frame body, and the support assembly is arranged adjacent to one of the strip plates.

[0017] When the rotating motor works, it drives the first connecting rod to rotate, and the first connecting rod is slidably connected to the vertical frame; since the vertical frame can only move vertically relative to the horizontal moving plate, and the horizontal moving plate can only move horizontally relative to the material transfer base, when the first connecting rod drives the vertical frame to move, the vertical frame can automatically move along the path on the track plate; after the vertical frame moves, it can drive the two strip plates to move, so that the clamping jaw cylinders drive the aluminum profiles to move. Since the clamping jaw cylinders are arranged in pairs, the material transfer assembly can perform loading and unloading synchronously. The first group of clamping jaw cylinders grab the aluminum profiles from the punching feeding line and place them on the positioning die of the pressing assembly, and the second group of clamping jaw cylinders grab the aluminum profiles that have been punched on the positioning die and place them on the support assembly; in this way, the aluminum profiles can be continuously loaded and unloaded, greatly improving the overall processing efficiency.

[0018] Preferably, the support assembly includes a support plate, a chip blowing head, and a waste recycling support; several support plates fixedly connected to the main frame body are arranged on the main frame body, and several discharge support members threadedly connected to the support plates are arranged on the support plates; the chip blowing head and the waste recycling support are respectively arranged at both ends of the main frame body, and both the chip blowing head and the waste recycling support are slidably connected to the main frame body; the chip blowing head is fixed to the main frame body by screws, and the waste recycling support is also fixed to the main frame by screws.

[0019] When the aluminum profile is placed on the support plate, it can be fixed due to the support of the discharge support member; then the chip blowing head works to blow out the waste inside the aluminum profile.

[0020] Compared with the prior art, the utility model has the following beneficial effects: 1. The aluminum profile is pressed and positioned by the pressing component, so that the position of the aluminum profile to be punched is aligned with the punching component, and the punching positioning is more accurate; 2. The punching component can accurately control the punching force, the punching force is more uniform, and the punching effect is better; 3. The feeding and discharging of the aluminum profile on the positioning die are synchronously carried out by the material transfer component, which greatly improves the overall processing efficiency of the aluminum profile.

[0033] The specific operation process of this embodiment is as follows. Place the aluminum profiles that need to be punched on the punching feeding line 2. When the aluminum profiles are transported to the alignment assembly 3 by the conveyor belt 21, the horizontal cylinder 33 controls the push plate 36 to approach the aluminum profiles, so as to align the aluminum profiles left and right; in this way, when the aluminum profiles are transported to the pressing assembly 4 by the material transfer assembly 6, there is no need to re-align, and when the aluminum profiles are placed down, they can just be directly placed on the positioning die 41 of the pressing assembly 4. Then the vertical cylinder 34 works to control the lifting of the aluminum profiles, so that the aluminum profiles can be separated from the conveyor belt 21; when the aluminum profiles are transported away by the material transfer assembly 6, the alignment assembly 3 repeats the above steps, and then the material transfer assembly 6 can continuously grab the aluminum profiles in turn.

[0034] When the aluminum profile is transported to the positioning die 41 of the pressing assembly 4, the first cylinder 43 works to drive the rack 46 to extend and retract. When the rack 46 extends and retracts, it drives the gear 45 to rotate. When the gear 45 rotates, it drives the pressing rotating shaft 44 to rotate. When the pressing rotating shaft 44 rotates, it drives the pressing member 47 to squeeze and contact the aluminum profile on the positioning die 41, thereby fixing the aluminum profile; in this way, the position of the aluminum profile that needs to be punched can be aligned with the punching assembly 5, and the punching effect is better. Then the punching assembly 5 starts to work. The oil cylinder 52 drives the strip-shaped push rod 55 to move. When the strip-shaped push rod 55 moves, it drives the punching movable side plate 53 to move along the guiding track 54. When the punching movable side plate 53 moves, it drives the punching die 51 to punch the aluminum profile on the positioning die 41.

[0035] After punching is completed, the material transfer assembly 6 works synchronously. The rotating motor 63 works to drive the first connecting rod 67 to rotate. The first connecting rod 67 is slidably connected to the vertical frame 66; since the vertical frame 66 can only move vertically relative to the horizontal moving plate 65, and the horizontal moving plate 65 can only move horizontally relative to the material transfer seat 62, when the first connecting rod 67 drives the vertical frame 66 to move, the vertical frame 66 can automatically move along the path on the track plate 64; after the vertical frame 66 moves, it can drive the two strip-shaped plates 69 to move, so that the jaw cylinder 61 drives the aluminum profile to move. Since the jaw cylinders 61 are arranged in pairs, the material transfer assembly 6 can perform feeding and discharging synchronously. The first group of the jaw cylinders 6 grabs the aluminum profile from the punching feeding line 2 and places it on the positioning die 41 of the pressing assembly 4, and the second group of the jaw cylinders 61 grabs the aluminum profile that has been punched on the positioning die 41 and places it on the support assembly 9; in this way, the aluminum profile can be continuously fed and discharged, greatly improving the overall processing efficiency.

[0036] The specific embodiments described herein are merely illustrative of the spirit of the present invention.
