Description

Technical Field

[0001] The utility model relates to the technical field of plate stamping feeding, in particular to a plate feeding rack for a heavy-duty stamping machine. Background Art

[0002] A stamping press is a device used to stamp out sheet metal parts. The specifications of a stamping press can be defined based on its maximum pressure and stamping capacity. Generally, if a stamping press has a rated pressure of more than 500 tons, it can be classified as a heavy-duty stamping press. A heavy-duty stamping press can generally stamp steel plates with a thickness of 10 mm. If the rated pressure of the stamping press is higher, it can stamp thicker steel plates.

[0003] The plates punched by heavy-duty stamping machines are generally heavy in weight. However, the existing technology still adopts the method of stacking more plates on the side of the stamping machine, and then the workers manually push the top plate into the stamping position of the stamping machine for loading. However, this method will firstly consume a lot of workers' physical strength, resulting in an inability to work for a long time. Secondly, the heavier plates will drop partly under the action of gravity, and the end of one plate will easily cause wear when in contact with the surface of another plate. Utility Model Content

[0004] In view of the above-mentioned defects, the utility model provides a plate loading rack for a heavy-duty stamping machine, which can reduce the difficulty of loading materials for workers, save physical strength, and reduce the wear of plates.

[0005] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0010] The pad wheel mechanism is arranged at one end of the plate frame, and includes a fourth linear mechanism arranged on the bracket and with the output direction pointing to the plate frame. A mounting portion is provided at one end of the output shaft, and a U-shaped frame is assembled on the outside of the mounting portion. A plurality of second fixed rods are arrayed on the inner sides of the two parallel sides of the U-shaped frame, and a plurality of second rollers are rotatably matched with the outer peripheral side of the second fixed rods.

A first fixing rod is provided between each pair of vertical plates on both sides of the panel frame, and multiple first rollers are rotatably matched on the outer peripheral side of the first fixing rod.

[0013] Furthermore, the panel lifting mechanism includes several vertically arranged first linear mechanisms, one end of whose output shaft is provided with a Z-shaped plate matching the horizontal opening. The Z-shaped plate at one end of the output shaft of a first linear mechanism and the Z-shaped plate opposite to the other side of the panel frame are combined into a U-shaped structure. When the U-shaped structure drops to the lowest point, the upper end surface of the bottom edge of the U-shaped structure is flush with the bottom surface inside the panel frame.

[0016] The beneficial effects of this technical solution are:

[0017] 1. It can automatically lift the plate and separate the top plate, and then feed the plate to the punching machine through the second roller and the first roller. When feeding heavier plates, it can reduce the difficulty of pushing and avoid wear between the plates.

[0018] 2. A second roller of different sizes and heights can be installed at one end of the mounting portion of the wheel pad mechanism to match panels of different thicknesses. BRIEF DESCRIPTION OF THE DRAWINGS
