Description

Technical Field

[0001] This utility model relates to the field of metal parts processing technology, specifically to an auxiliary feeding mechanism for a sheet metal shearing machine. Background Technology

[0002] Sheet metal shearing machines are key cold-working equipment in metal parts processing. Their core function is to cut metal sheets to length, serving as a fundamental step before metal parts are formed. They use blade shearing force to cut raw materials such as cold-rolled steel and stainless steel into blanks required for metal parts processing. They are suitable for the initial sheet metal cutting stage in industries such as machinery and automotive, producing metal structural parts and hardware. Various models, including mechanical and hydraulic types, are available to suit different processing needs.

[0003] Traditional manual feeding of sheet metal to a shearing machine has many shortcomings. Manual feeding is prone to errors in sheet metal positioning due to hand tremors and visual errors, resulting in inaccurate cutting dimensions and failing to meet high-precision processing requirements. The sheet-by-sheet operation method is inefficient, and worker fatigue further slows down the processing pace. Hands close to the blade working area are prone to safety accidents such as pinching and cutting. Therefore, those skilled in the art provide an auxiliary feeding mechanism for sheet metal shearing machines to solve the problems mentioned in the background art. Utility Model Content

[0021] Furthermore, the output end of the first motor 41 drives the first connecting rod 42 and the first sprocket 51 to rotate, which in turn drives the second connecting rod 43 to make a circular motion on the side close to the first connecting rod 42. At the same time, the third connecting rod 44 is driven and swings inside the conveyor frame 1. Through the chain 53, the second sprocket 52 is driven to rotate, thereby driving another set of first connecting rod 42, second connecting rod 43 and third connecting rod 44 to move. The cooperation of the two sets and the sliding of the balance bar 46 inside the slide 47 drive the push plates 45 on both sides to simultaneously convey the plate, thus playing a conveying role.

[0022] As one implementation method in this embodiment, please refer to Figure 4 As shown, the auxiliary conveying assembly 2 includes a fixed rod 21, which is fixed to the top inner side of the conveying frame 1. A roller 22 is rotatably connected to the outer wall of the fixed rod 21. The fixed rod 21 and the roller 22 are provided in multiple sets and are distributed in a linear array.

[0023] The fixed assembly 3 includes a conveyor plate 31, which is slidably connected to the top of the conveyor frame 1. The conveyor plate 31 is slidably connected to the roller 22. Multiple clamping plates 32 are fixedly connected to the front and rear sides of the conveyor plate 31. An adjusting rod 33 is threadedly connected to the top surface of the conveyor plate 31. A knob 34 is fixedly connected to the top surface of the adjusting rod 33. Multiple sets of adjusting rods 33 and knobs 34 are provided and are symmetrically distributed.

[0024] Furthermore, the sheet material is placed inside the conveyor plate 31, and the knob 34 is manually turned to drive the adjusting rod 33 to rotate.

The multiple through slots on the side of the connecting frame 62 facilitate observation.

[0028] Working principle: Place the sheet material inside the conveyor plate 31, manually turn the knob 34 to rotate the adjusting rod 33. The adjusting rod 33 is threadedly connected to the conveyor plate 31, causing the adjusting rod 33 and the knob 34 to move downwards, thus fixing the sheet material. The output of the first motor 41 drives the first connecting rod 42 and the first sprocket 51 to rotate, causing the second connecting rod 43 to move in a circular motion near the first connecting rod 42. At the same time, the third connecting rod 44 is driven and swings inside the conveyor frame 1. Through the chain 53, the third connecting rod 44 drives the second sprocket 52 to rotate, thereby driving another set of first connecting rods 42, second connecting rods 43 and third connecting rods 44 to move. The cooperation of the two sets and the sliding of the balance bar 46 inside the slide chute 47 drive the push plates 45 on both sides to move. When they move to the middle and upper part, the clamping plate 32 abuts against the top of the push plate 45, thereby conveying the fixed component 3 along with the plate. During conveying, the conveyor plate 31 moves on top of the roller 22, driving the roller 22 to rotate and reducing friction. The output of the second motor 71 drives the conveyor output shaft 72 to rotate, driving the conveyor belt 74 to move. The anti-slip blocks on the outside of the conveyor belt 74 provide anti-slip function, making it easy to convey the fixed component 3 back. The multiple through slots on the side of the connecting frame 62 facilitate observation.
