Description

Technical Field

[0001] The utility model discloses a moving limiting mechanism for a forging tray, belonging to the technical field of forging. Background Art

[0002] The existing hot die forging press fully automated production line uses a temperature-controlled cooling system for cooling when forging crankshafts. The forgings are placed on a tray, which moves on a temperature-controlled cooling conveyor belt. The lower side stop of the conveyor belt limits the tray's movement, and a rotating mechanism changes the tray's movement.

[0003] With the continuous progress and development of the forging industry, the continuous and stable operation of the production line is becoming increasingly important, and the stability of the production line equipment is gradually becoming more prominent.

[0004] Under the existing technology, the stopper on the lower side of the conveyor belt limits the material tray. Since the stopper is an upper and lower structure, it will be hit and shaken by the material tray during limiting, causing the material tray to be inaccurately positioned, the cylinder to shake, and the seal to be damaged due to the impact.

[0005] Examples of prior art include Figure 1 As shown in the figure, during the conveying process of forgings, the forgings are placed on top of the material tray, which moves along with the conveyor belt. When the material tray reaches the stop, the stop cylinder is activated to push the stop upward, limiting the movement of the material tray. When the material tray needs to continue moving, the stop cylinder retracts and drives the stop downward, allowing the material tray to move and continue moving on the conveyor belt, completing the operation. The existing stop structure has the following problems during use:

[0006] The stopper will shake when hit by the material tray, causing the tray to be inaccurately positioned when it stops, and interfere with the side plate of the conveyor belt. When the stopper retracts, the tray will be stuck when it moves.

[0007] The up and down movement of the stopper mainly depends on the movement of the cylinder. When the cylinder shakes at the stopper, the cylinder rod shakes, and the oxide scale on the equipment will fall onto the cylinder seal, causing damage to the cylinder seal.

[0008] The cylinder on the lower side of the stop is vertical. When the material tray hits it, the cylinder will pull the cylinder, and the cylinder fixed base will shake and crack, causing the pallet to be fixed unevenly, the conveyor belt to be stuck, and the cylinder to be stuck on the pallet. Utility Model Content

[0009] The purpose of the utility model is to solve the problems that occur in the use of the existing stop structure and to provide a forging tray movement limiting mechanism.

[0012] The stop mechanism includes a stop seat arranged at the bottom of the mechanism support frame, and a guide plate and a fixed seat are respectively provided on the stop seat, and a stop cylinder is provided on the stop seat at one end of the fixed seat away from the guide plate, and the execution end of the stop cylinder is connected to one end of the guide block, and rollers that roll on the guide plate are provided on both sides of the guide block near the other end. The two rollers are connected by a roller shaft, and the roller shaft in the groove in the middle of the guide block is hinged to one end of the connecting shaft, and the other end of the connecting shaft is hinged to the corner of the L-shaped stop block, and the long side end of the L-shaped stop block is hinged to the top of the fixed seat through the hinge shaft.

[0013] Preferably, the conveying mechanism includes two pairs of driving sprockets and driven sprockets which are respectively rotatably arranged on the inner sides of the two ends of the mechanism support frame. The two pairs of driving sprockets and driven sprockets are connected together by two transmission chains. The two driving sprockets are connected by a rotating shaft, and one end of the rotating shaft is connected to the main shaft of the motor.

[0014] Preferably, the material tray includes a material tray support mounted on two transmission chains, and the material tray support is symmetrically provided with a material tray bracket for placing forgings.

[0015] Preferably, baffles are symmetrically arranged on the top of the mechanism support frames on both sides of the conveying mechanism.

[0016] The present invention has the following beneficial effects compared with the existing ones:

[0017] The utility model provides a forging tray movement limit mechanism, in which the stop cylinder is aligned with the moving direction of the material tray and is arranged horizontally, reducing the impact of the material tray on the cylinder body, and the cooperation of the fixed seat and the L-shaped stop block swing limit solves the problem of the stop shaking caused by the large horizontal impact, thereby avoiding the material tray from getting stuck in the conveying mechanism, and at the same time, because the cylinder is arranged horizontally, the oxidized scale falling off the side of the material tray will not fall onto the cylinder, and the cylinder seal is greatly protected.
