Description

Technical Field

[0036] like Figures 1 to 5 The cooler oil fin automatic high-speed gear hobbing punching production line shown in the figure includes a feeding mechanism 100, a forming mechanism 200, a cutting mechanism 300 and a conveying mechanism 400;

[0037] The feeding mechanism 100 is provided with a cutting mechanism 300 and a pushing mechanism 600 in sequence on one side, the forming mechanism 200 is located at the upper part of the pushing mechanism 600, and the conveying mechanism 400 is arranged opposite to the pushing mechanism 600;

[0038] The molding mechanism 200 includes a support 201, an upper mold part 202 and a lower mold part 203. The upper mold part 201 and the lower mold part 202 are both arranged on the support 201, and the upper mold part 202 is vertically located at the top of the lower mold part 203;

[0039] The upper mold part 202 includes an upper driving mechanism 2021 and an upper module 2022. The upper driving mechanism 2021 is located at the top of the upper module 2022, and the upper driving mechanism 2021 is connected to the upper module 2022. The upper driving mechanism in the present application is a cylinder. Both ends of the upper module 2022 are respectively connected to sleeves 2023, and the sleeves 2023 are sleeved on the bracket 201.

[0040] The lower mold part 203 includes a lower mold block 2031 , and mold splitting mechanisms 500 are respectively disposed between two sides of the upper mold block 2022 and two sides of the lower mold block 2031 .

[0041] The production line of the present invention realizes the transportation of the raw material of the fin, i.e. the sheet material, through a feeding mechanism, and then cuts the fin after being formed by a forming mechanism, and finally transfers the formed and cut fin to a conveying mechanism through a pushing mechanism to complete the production of the fin. The present invention has a high degree of automation in the production of the fin and high production efficiency.

[0042] like Figures 4 to 6 The mold splitting mechanism 500 includes a first movable rod 501, a second movable rod 502, a connecting frame 503, a limiting rod 504 and a push block 505;

[0043] One end of the first movable rod 501 and one end of the second movable rod 502 are fixedly connected and then rotatably connected to one end of the connecting frame 503, and the other end of the connecting frame 503 is connected to the top of the upper module 2022; specifically, one end of the first movable rod and one end of the second movable rod in the present invention are fixedly connected to one end of the connecting frame through a rotating shaft, that is, the first movable rod and the second movable rod can rotate along the connecting frame;

[0044] The other end of the first movable rod 501 is a first free end, on which a first wedge block 5011 is disposed; the other end of the second movable rod 502 is a second free end, on which an insertion rod 5021 is disposed;

[0045] The push block 505 is located on one side of the lower module 2031, and a groove 5051 is provided on one side of the push block 505 close to the second free end, and the insertion rod 5021 is matched with the groove 5051;

[0046] One end of the limiting rod 504 is connected to one side of the lower module 2031, and the other end is a fixed free end, which extends toward the upper module. A limiting wedge block 5041 is provided on the fixed free end, and the first wedge block 5011 and the limiting wedge block 5041 are matched.

[0047] After the upper module and the lower module complete the forming action on the fins and are cut by the cutting mechanism, the upper module and the lower module need to be separated, and then the fins are pushed onto the feeding mechanism through the pushing mechanism; in the present application, when the mold is separated, the upper module moves upward under the action of the upper driving mechanism. Since one end of the connecting frame is connected to the top of the upper module, the upper module drives the connecting frame upward during the upward movement, and then drives the first movable rod and the second movable rod on the connecting frame to move upward. When the first wedge block on the first movable rod abuts against the limiting wedge block on the limiting rod, the insertion rod on the second movable rod is matched and located in the pushing block groove. In the process of further upward movement of the upper module, the first wedge block is driven to move upward, and the first wedge block is squeezed by the limiting wedge block. The first movable rod and the second movable rod rotate along the connecting frame at the same time, so that the insertion rod on the second movable rod is inserted into the groove. In the process of continuing to move the upper module upward, the insertion rod is inserted into the push block to drive the push block to move upward, so that the push block pushes out the fins on the lower module, completes the mold separation of the upper and lower modules, improves the demoulding efficiency of the fins, and thus improves the production efficiency of the fins.

[0048] In the present application, the separation between the upper module and the lower module is achieved by moving the upper module upward. At the same time, the upward moving upper module drives the connecting frame to finally drive the push block to move upward, thereby ejecting the fins. The present invention does not need to set up other structures separately. The fins are ejected while the upper and lower modules realize film separation, thereby improving the mold separation and demolding efficiency after the fins are formed. The high degree of automation greatly improves the production efficiency of the fins and avoids the safety hazard of manually taking the fins.

[0049] In the present application, a spacing is left between the push block 505 and the side wall of the lower module 2031, and an airbag 506 is provided on the side of the push block 505 close to the lower module 2031. The airbag 506 is connected to the inflation mechanism, and the top of the airbag 506 is arranged flush with the top of the push block 505. The airbag 506 is long and strip-shaped, and the airbag 506 extends toward the center of the lower module when inflated. After the push block is inserted into the insertion rod and driven to move upward to separate the fin from the lower module, gas can be injected into the airbag through the inflation mechanism, so that the airbag is full, and the support at the center of the fin is achieved through the airbag. In the process of the push block continuing to move upward, the airbag is driven to move upward at the same time, so that the center and both sides of the fin move upward synchronously, avoiding the fin being moved upward only by the push blocks at both ends of the fin, causing deformation or curling at both ends of the fin, ensuring the forming quality of the fin, and improving the production efficiency of the fin. After the fin ejection action is completed, the fin can be ejected to the conveying mechanism through the pushing mechanism on one side; after the fin pushing is completed, the new sheet moves to the corresponding upper and lower modules, the inflation mechanism is abandoned, the gas in the airbag is discharged, the upper module moves downward, driving the connecting frame to move downward, and at the same time driving the first and second movable rods to move downward. When the first wedge block on the first movable rod is not squeezed by the limiting wedge block, the insertion rod is separated from the groove, and the push block is reset at this time to prepare for the next ejection.

[0050] The bottom end of the push block 505 is set on the limit rod 504, so that the push block moves up and down along the limit rod, ensuring the stability of the up and down movement of the push block; in order not to affect the forming of the fins and avoid the push block pushing out of the fins and causing the side of the fins to deform, the top end of the push block 505 is lower than the lower module 2031 or is set flush with the lower module 2031.

[0051] A guide rod 5042 is provided on the limit rod 504, and the push block 505 is inserted into the guide rod 5042, and one end of the guide rod 5042 is kept extending into the push block and the other end extends out of the push block. A limit block 5043 is provided at one end of the guide rod extending into the push block, and the push block is limited by the limit block to prevent the push block from escaping from the limit rod, thereby further ensuring the stability of the push block moving up and down along the limit rod. A spring 5044 is provided on the outer ring of the guide rod extending out of the push block, and one end of the spring 5044 is connected to the limit rod, and the other end is connected to the bottom end of the push block. The stability of the push block resetting along the limit rod is achieved by setting the spring.

[0053] As a preferred embodiment, the shaping device in the present application includes a movable pressing wheel 103 and a fixed pressing wheel 104. There are at least two movable pressing wheels 103, and the two movable pressing wheels 103 are respectively arranged on both sides of the fixed pressing wheel 104; that is, the curled sheet is flattened by the movable pressing wheel and the fixed pressing wheel respectively to ensure the flatness of the sheet. The movable pressing wheel 103 in the present application is connected to the cylinder 105, and the movable pressing wheel can be driven by the cylinder to achieve different positions of the movable pressing wheel on the width of the conveyor belt to adapt to sheets of different widths, or to focus on flattening a part of the sheet, thereby improving the applicability of the shaping device and ensuring the subsequent fin quality.

[0054] The cylinder 105 is arranged on a support 106, a base 107 is provided at the bottom end of the support 106, a screw motor is provided on the base, and a screw 108 of the screw motor passes through the support; by starting the screw motor, the screw rotates, and finally the support moves up and down along the screw, thereby adjusting the up and down movement of the cylinder, and the cylinder drives the spacing between the movable pressure wheel and the conveyor belt to realize the pressure of the movable pressure wheel on the sheet to be leveled, thereby improving the leveling efficiency of the movable pressure wheel for different sheets and improving the applicability of the movable pressure wheel.

[0055] A guide plate 1011 is provided on one side of the conveyor belt 101, one end of the guide plate 1011 is fixedly connected to the inner wall of the conveyor belt, and the other end of the guide plate is a guiding free end. The guide plate is used to guide the sheet on the conveyor belt so that the sheet is located in the middle of the conveyor belt, preparing for subsequent shaping and ensuring the shaping effect.

[0056] A telescopic rod is provided between the free end of the guide plate and the conveyor frame on the side of the conveyor belt, and the telescopic rod includes an inner rod 1013 and an outer rod 1012. One end of the inner rod 1021 is rotatably connected to the free end of the guide plate, and one end of the outer rod 1022 is arranged on the inner wall of the conveyor frame. The other end of the inner rod 1013 is connected to the inside of the other end of the outer rod by a thread. By rotating the inner rod 1013, the inner rod 1013 rotates along the free end of the guide plate and the inner rod extends or retracts into the outer rod, thereby realizing direct adjustment of the distance between the free end of the guide plate and the conveyor frame on the other side of the conveyor belt, so as to adapt to sheets of various widths and improve the applicability of the guide plate.
