Description

Technical Field

[0001] The invention relates to the technical field of automatic feeding production of sawing machines, in particular to an automatic feeding device for sawing machines. Background Art

[0002] A saw is a type of metal cutting machine primarily used for sawing angle steel, channel steel, pipes, and other structural steel materials. Existing semi-automatic, manually fed saws are inexpensive and widely used, but they still require manual operation for loading, feeding, measuring, and cutting. Handling metal bars requires high physical effort, is labor-intensive, and inefficient. Frequent back-and-forth feeding can lead to fatigue, increasing the risk of accidents and compromising cutting accuracy. However, some newer saws lack a post-feed clamping mechanism or have it separate from the feed mechanism. Instead, the feed mechanism advances and then uses a clamping system to hold the bar in place. This can cause the bar to slip, resulting in poor feeding accuracy. As the bar shortens, the cut bar can also roll, leading to uneven cut ends and, in severe cases, damage to the saw blade. To address this issue, we offer an automated feeding device for saws. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides an automatic feeding device for a sawing machine, which solves the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automatic feeding device for a sawing machine, comprising two feeding device brackets and a CNC computer installed on one of the feeding device brackets, the feeding device bracket being provided with a side panel, the side panel being provided with a main feed servo motor, both ends of the side panel being provided with connecting fixings, one end of the connecting fixing being fixed to the feeding device bracket by a bolt, and the other end being fixed to the side panel by a bolt.

[0005] Optionally, a lifting frame is provided in the feeding device bracket, one end of the ball screw passing through the lifting frame is connected to the lifting reducer, and the other end is movably connected to the feeding device bracket, and the input end of the lifting reducer is connected to the lifting servo motor.

[0006] Optionally, a plurality of upper auxiliary feed rollers are equidistantly distributed in the axial direction of the lifting frame, and both ends of the upper auxiliary feed rollers are movably connected to two lifting frames respectively, and the input end of one of the upper auxiliary feed rollers is connected to an auxiliary feed reducer, and the input end of the auxiliary feed reducer is connected to an auxiliary feed servo motor.

[0014] 1. The present invention combines the new sawing machine currently produced with automatic feeding, uses servo motor braking, and synchronous belt for compaction, without the need for a separate compaction mechanism. The rubber belt is soft in texture and can compact bars of the same specification at the same time. Multiple bars of the same specification can be placed for sawing, thereby improving the sawing efficiency.

[0015] 2. The present invention can be produced separately and can be used for upgrading and renovating old sawing machines. It is easy to install and does not damage the original equipment.

[0016] 3. The feature of the present invention is that it integrates feeding and fixing. Compared with the products on the market that require a special clamping device after feeding, the present invention integrates feeding and clamping. The structure and control are completely different from existing products. In addition, the present invention adopts a servo motor to control feeding. Compared with similar products, it has higher feeding accuracy. Photoelectric sensing is used to measure feeding and feedback correction, which provides reliable guarantee for precision control.

[0017] 4. The present invention synchronizes feeding and fixing, and does not require a separate pressing device. An auxiliary feeding device is used for pressing to prevent the sawing bar from rolling. The steps are simple and the processing efficiency is improved. For workers, it is freed from simple and repetitive work. The old sawing machine can be upgraded and modified to improve the degree of automation. The installation is simple and there is no need to modify the original equipment. It provides a practical upgrade solution for machining plants that are unable to replace new sawing equipment.
