[0016] The use process of the tube mold automatic loading system is as follows: System startup: First, start the entire tube mold automatic mold loading system and ensure that all subsystems (mold loading base system, tie rod feeding system, tie rod sleeve system, tie rod transfer system, tie rod conveying system) are in standby mode.

[0017] Tube mold placement: Place the tube mold to be loaded between the active steel wheel group 3 and the passive steel wheel group 4 of the mold loading base system to ensure that the outer circumference of the bottom of the tube mold is in close contact with the tube mold contact surface formed by the outer circumference of the top of the steel wheel group.

[0018] 2. Tie rod feeding stage Tie rod feeding: Start the roller driving mechanism of the tie rod feeding system, and feed the tie rod through the tie rod feeding driving roller group. Driven by the roller group, the tie rod moves forward along a predetermined path.

[0019] Steel brush dust removal: When the pull rod enters the steel brush dust removal mechanism, the active steel brush 10 and the passive steel brush 9 rotate under the drive of the turbine reduction motor to remove dust from the surface of the pull rod to ensure that the surface of the pull rod is clean and free of impurities.

[0020] Tie rod clamping: Subsequently, the tie rod enters the tie rod clamping mechanism, and the flip plate telescopic power mechanism 43 drives the flip plate 14 to approach the passive clamping wheel 13, and the tie rod between the active clamping wheel group 44 and the passive clamping wheel 13 is clamped to ensure that the tie rod will not fall off or shift in subsequent operations.

During the conveying, the rear end of the rod is abutted until the rod is pushed to the next workstation. The reason for this is that the radius of the end of the rod is small, and at this time the gap between the driving wheel and the driven wheel is too large to effectively convey the end of the rod. We design the outer diameter of the U-shaped rod 16 to be the outer diameter of the middle of the rod, and when the rod is about to complete the feeding, the U-shaped rod 16 is inserted between the driving wheel and the driven wheel, causing the U-shaped rod 16 to be forced to be conveyed, and during the conveying of the U-shaped rod 16, its front end abuts against the end of the rod, so that the rod continues to be forced to be conveyed, thereby ensuring stable advancement of the rod.

[0022] Tie rod sleeve: When the tie rod enters the tie rod sleeve system, the inner beveled steel sleeve 18 and the outer beveled steel sleeve 19 cooperate to sleeve the hose onto the tie rod, and the outer beveled steel sleeve telescopic power mechanism 22 drives the outer beveled steel sleeve 19 along the slide rail toward the inner beveled steel sleeve 18, compressing the hose and jamming it. At this time, the external bolt fasteners can be tightened on the bolt holes of the outer beveled steel sleeve 19 to further compress the hose. At this time, the sleeve operation of the tie rod is completed when the tie rod is fed, that is, the tie rod is inserted into the hose.

[0023] 4. Tie rod transfer stage The hose seat 25 turns over: when the pull rod completes the sleeve, the hose seat 25 turning mechanism is started, and the hose seat cylinder 26 drives the hose seat 25 to swing, so that the hose inside it naturally slides into the tipping bucket 29 below the inclined surface 28.

[0024] Tipping of the bucket 29: When the number of hoses in the bucket 29 reaches a certain number, the bucket telescopic power mechanism 31 drives the bucket 29 to tilt, so that all the hoses contained therein are tipped toward the side away from the inclined surface 28 into the receiving groove of the cantilever beam 35.

[0025] 5. Tie rod conveying stage The rail car 33 moves: the rail car 33 moves along the track 32 to below the tipping bucket 29 , and the receiving groove on the cantilever beam 35 receives the hose dumped out by the tipping bucket 29 .

[0026] The cantilever beam 35 is skewed: when the rail vehicle 33 carries the cantilever beam 35 into the pipe mold at the other end of the rail 32, the telescopic tube on the electro-hydraulic actuator 39 is extended and retracted, causing the drive shaft 38 to move, and the turntable and the drive shaft to rotate at a certain angle, causing the cantilever beam 35 fixedly connected to the drive shaft 38 to become skewed.

[0027] The tie rod is tilted: the tie rod with the rubber hose on the cantilever beam 35 is completely tilted into the tube mold under the effect of the tilting of the cantilever beam 35, completing the entire mold loading process.

[0028] 6. System Reset and Subsequent Operations System reset: After completing a mold loading operation, each subsystem automatically resets to the initial state and prepares for the next mold loading operation.

[0029] Subsequent operations: According to production requirements, multiple mold loading operations can be performed continuously until the mold loading tasks of all tube molds are completed.
