Description

Technical Field

[0001] The invention relates to the technical field of automobile roof forming dies, in particular to an automobile roof forming dies with a closed-in-place detection mechanism. Background Art

[0002] The automobile industry is a comprehensive enterprise developed on the basis of many related industries and related technologies. Products of many departments are used in automobiles, and various processing technologies are required from blank processing to vehicle assembly. Automobile parts include thousands of different parts ranging from floors to screws. The actual automobile production process is completed by a number of different professional manufacturers. The roof cover is the cover on the top of the car. For the overall rigidity of the car body, the roof cover is not a very important part. This is also the reason why a skylight is allowed on the roof cover. For the overall rigidity of the car body, the roof cover It is not a very important component, which is also the reason why a skylight is allowed on the roof cover. From a design point of view, what is important is how it smoothly transitions with the front and rear window frames and the junction with the pillars to obtain the best visual sense and minimum air resistance. Of course, for safety, the roof cover should also have a certain strength and rigidity. Generally, a certain number of reinforcing beams are added under the roof cover, and insulating cushioning materials are laid on the inner layer of the roof cover to prevent the conduction of external temperature and reduce the transmission of noise during vibration. The car roof forming mold is an important component for manufacturing the car roof, and it needs to be flattened and positioned in a molded manner to complete the stamping production operation.

[0003] For example, the patent document with the announcement number CN 212285571 U discloses a car roof forming mold, which belongs to the field of car roof manufacturing technology. The car roof forming mold includes a base, a support frame is welded to the top outer wall of the base, an air outlet is opened on one side outer wall of the support frame, a placement table is welded to the top outer wall of the support frame, an air duct is fixed to the top outer wall of the support frame by screws, a blower is fixed to the top outer wall of the placement table by screws, the other end of the air duct is fixed to the top outer wall of the blower by screws, a fixing groove is opened on one side outer wall of the lower mold, an air pump is fixed to the top outer wall of the placement table by screws, and a pneumatic tappet is fixed to the bottom outer wall of the placement table by screws. The utility model blows out air through a blower, transmits it through the air duct, and blows it out through the air outlet, which can blow air to the surface of the mold, so that the air around the mold flows quickly, and the surface is free of dust and residues. At the same time, the wind force is strong and has a good cooling effect on the mold.

[0004] However, when the structure is actually stamping the automobile roof forming mold, it is often only possible to use a simple manual verification method to ensure the upper and lower molds are closed in place. However, daily automobile roof forming requires multiple stamping stages, and each stage often requires a closed in place detection operation. This operation is time-consuming and labor-intensive, affecting the overall production efficiency of the automobile roof. In addition, manual detection often has large error problems, and it is impossible to complete each closed in place detection operation more accurately and reliably. At the same time, the equipment cannot perform rapid loading and unloading adaptation and docking operations on the entire automobile roof, and it is also impossible to ensure that the automobile roof forming mold completes the closed in place operation more efficiently and adaptably, and cannot meet daily use needs. Therefore, it is urgent to design an automobile roof forming mold with a closed in place detection mechanism to solve the above problems. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The automobile roof forming mold with a closed position detection mechanism can enable the equipment to perform a more efficient closed position detection operation that is more compatible with the automobile roof forming mold by arranging a processing frame, a detection ring frame, a ring rail frame, a movable rail groove, a driving wheel seat, a detection frame, an air flow sensor, a fine-tuning bite airbag, a top pressing seat, a shrinking frame, a hydraulic unit, an air leveling base, a fan frame, an air suction grid frame, a ventilation seat, an exhaust detection groove, a connecting sleeve and an air leveling duct. In actual use, the staff first puts the automobile roof forming mold that needs to be stamped up and down into the interior of the processing frame as a whole, and performs adaptive top connection up and down through the top pressing seat inside the processing frame, and then simultaneously starts the hydraulic unit at one end of the shrinking frame at the upper and lower ends of the processing frame to perform a step-by-step stamping operation of the automobile roof forming mold synchronously up and down. During the stamping process, the fan frame at the bottom of the air leveling base can be started first to quickly inhale from the air suction grid frame, and transport the airflow from the inside of the air leveling base along the four sides of the air leveling duct to the side of the bottom shrinking frame. The ventilation connector is directly injected into the automobile roof forming mold inside the processing frame, and then the airflow can be lifted and discharged evenly from the side joints of the upper and lower molds of the automobile roof forming molds, and the driving wheel seat is started at the same time to drive the detection frame as a whole to perform a limited sliding operation inside the moving track groove of the annular rail frame, so that the detection frame as a whole rotates in a circle along the annular rail frame, and the airflow at the joints of the automobile roof forming mold flows out evenly in a circle from the exhaust detection groove of the processing frame, and the airflow out of the joints of the upper and lower molds can be detected by the airflow sensor at the center of the detection frame. When uneven airflow is detected, the upper and lower fine-tuning bite airbags of the inner wall of the detection frame can be adaptively started to perform the top connection adjustment operation of the upper and lower molds of the automobile roof forming, and the closed position that is not in place can be quickly integrated and leveled. The equipment can be repeatedly stamped with the ceiling forming mold, and continuous multiple closing adjustments can be performed to adaptively complete the closed position detection operation, which reflects the practicality of the equipment design.

[0018] The automobile roof forming mold with a closed-in-place detection mechanism further improves the overall use effect of the equipment by arranging a lower cross joint, an extension seat, an overhead seat, a feed frame, a damping shaft, a docking pressure plate, a lifting seat, an upper cross joint, a transmission cover, a driving motor, a transmission belt, a reciprocating screw, an extension rod, a bearing seat, a limit slide seat, a screw sleeve, a limit slider, a damping rubber pad, a damping rubber strip and a sealing rubber ring. In daily use, the staff can start the driving motor at one end of the transmission cover to drive the reciprocating screws at both ends to perform an adaptive rotation adjustment operation through the transmission belt at one end. The reciprocating screw can perform a stable rotation adjustment operation inside the lifting seat through the extension rod and the bearing seat at the bottom end. Then the screw sleeve on its surface can cooperate with the limit slider and the damping rubber pad on the back to perform a stable up and down lifting and lowering adjustment operation of the limit slide as a whole. The limit slide can be subjected to the damping fitting operation of the damping rubber strip on the side of the lifting seat.
