Description

Technical Field

[0001] The utility model relates to the technical field of metal plate stamping and feeding, in particular to a feeding mechanism used for metal plate stamping and forming. Background Art

[0002] Stamping is a forming method that relies on a press and a die to apply external force to the sheet material to cause it to undergo plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. Before a metal sheet is formed, two or more sheets need to be stacked together and then stamped, so that the metal sheet can be stamped into shape. However, before stamping, it is usually necessary to manually place the metal sheet in the stamping groove before subsequent stamping work can be performed. For example, when making aluminum gussets, it is necessary to manually place the metal sheet into the stamping die, and then manually press the switch to close the die. However, this feeding method currently has the potential safety hazard of machine injuries, and hands are often injured. It is also inconvenient to take out the stamped metal sheet, which adds difficulty to the feeding and stamping work. In view of this, we propose a feeding mechanism for metal sheet stamping.

DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Embodiment 1

[0020] like Figure 1-3As shown, the feeding mechanism for metal plate stamping and forming proposed by the utility model comprises a working frame 1, a support plate welded to the back of one of the support legs of the working frame 1, and a motor 54 fixedly mounted on the support plate. The frame body of the working frame 1 is provided with a plurality of rotating holes, and bearings are installed in the plurality of rotating holes. Both ends of the plurality of rollers 51 are connected to the bearings, and one of the rollers 51 passes through the bearing and is connected to the output end of the motor 54, and the motor 54 is used to rotate the rollers 51. A stamping groove is provided on the working frame 1. The conveyor belt 52 is sleeved on the outer rings of the plurality of rollers 51, and a plurality of paddles 53 are fixedly welded on the surface of the conveyor belt 52. The plurality of paddles 53 are arranged in groups of two, and the distance between each group of paddles 53 is the same, and are used to paddle the metal plate to move. The unloading platform 4 is arranged on the back of the working frame 1 and is fixedly connected thereto, and the guide bar is fixedly welded in the groove opened on the top of the unloading platform 4, and the guide bar is located in the slide groove opened at the bottom of the slider 61 and is adapted thereto, and is used to limit the moving direction of the slider 61. The electric push rod 66 is fixedly installed in the groove, and the output end of the electric push rod 66 is fixedly connected to the back of the slider 61, which is used to push the slider 61 to slide. The guide rod 63 passes through the through hole opened on the feed plate 64 and is fixedly connected to the top of the slider 61 to prevent the feed plate 64 from rotating. The bolt 62 passes through the threaded hole opened on the feed plate 64 and is connected to the bearing set on the top of the slider 61 to adjust the height of the feed plate 64. A plurality of suction cups 65 are fixedly installed on the plate wall facing the feed plate 64.

[0021] In this embodiment, the metal plates to be stamped are stacked and placed on the discharge table 4, and the electric push rod 66 is started to push the slider 61 to move, and the metal plates are pushed onto the conveyor belt 52, so that the metal plates are located between the two dial plates 53. At this time, the motor 54 is started to drive one of the rollers 51 to rotate, and the other rollers 51 cooperate to drive the conveyor belt 52 to rotate, so that the metal plates are fed into the stamping groove, thereby realizing the feeding work, and making the position of the discharge place far away from the stamping place, so as to avoid accidental injury to the staff when the metal plates are stamped, and at the same time improve the safety of this equipment during operation. Safety during stamping: when the metal plate is thicker, the height of the feed plate 64 can be adjusted by screwing the bolt 62, so that metal plates of different thicknesses can be pushed conveniently. The guide rod 63 prevents the feed plate 64 from rotating with the bolt 62. When the slider 61 and the feed plate 64 push the metal plate, multiple suction cups 65 suck the back of the metal plate to slightly limit its position to avoid position displacement during pushing. When the metal plate is pushed between the two paddle plates 53, the conveyor belt 52 drives the paddle plate 53 to rotate, thereby releasing the adsorption relationship between the metal plate and the suction cup 65.
