Description

Technical Field

[0001] The utility model relates to a steel bar magnetic adsorption feeding system, belonging to the technical field of steel bar processing. Background Art

[0002] Steel bars are in strip structures. During processing (such as bending hoops, cutting, etc.), the steel bars need to be arranged regularly in a certain direction and feeding is completed. The feeding method of the existing feeding mechanism is to first batch-feed the steel bars uniformly, and then sort the irregular steel bars after feeding through jigs or vibrating boxes to complete the feeding.

[0003] The current technology has incomplete considerations and has the following drawbacks: The steel bars bought from the manufacturer are all in one whole long section. To meet different usage requirements, various lengths of short steel bars need to be cut from the long steel bars. Currently, when cutting long steel bars, generally the overhead crane feeding method is adopted. This overhead crane feeding method can meet certain usage requirements, but there are also relatively large defects. Each time, only a very small number of steel bars can be lifted, and it is necessary to wait until the steel bars are cut before re-lifting the materials. The production efficiency is low, it takes a long time, professional crane drivers are required for operation, the operation difficulty is large, the usage cost is high, and it cannot effectively meet the production and on-site usage requirements.

[0004] To solve one of the above problems, there is an urgent need for a steel bar magnetic adsorption feeding system. Content of the Utility Model

[0005] According to the above deficiencies in the prior art, the technical problem to be solved by the utility model is: how to achieve continuous and uninterrupted feeding of steel bars, and for this purpose, a steel bar magnetic adsorption feeding system is provided.

[0006] The steel bar magnetic adsorption feeding system described in the utility model includes a cross beam 1. At both ends of the cross beam 1, a set of track walking structure devices 2 moving along the corresponding ground tracks 3 are respectively installed. The two groups of ground tracks 3 are parallel to each other and are both installed on the ground. It is characterized in that: an elevating electromagnet adsorption mechanism 1.2 and an elevating telescopic material receiving mechanism 1.3 are installed in the middle of the cross beam 1. On both sides of the elevating electromagnet adsorption mechanism 1.2, a set of horizontal material spreading moving mechanisms 1.4 that can move along the length direction of the cross beam 1 are respectively arranged. The cross beam 1 is a rectangular tubular structure, having a front side and a rear side arranged oppositely and a top surface and a bottom surface arranged oppositely. Along the length direction of the bottom surface of the cross beam 1, multiple groups of pneumatic telescopic material receiving mechanisms 1.5 are arranged at intervals.

[0007] This device is used to transfer the steel bars in the steel bar bin to the feeding side of the existing horizontal feeding rack. The specific operation is as follows.

[0008] Step 1: Stack multiple steel bars to be transferred in the steel bar bin. First, control the crossbeam 1 to move to one side of the steel bar bin, then lower the lifting electromagnet adsorption mechanism 1.2 to the low position. The electromagnet of the lifting electromagnet adsorption mechanism 1.2 is powered on, and the lifting electromagnet adsorption mechanism 1.2 is used to adsorb multiple adjacent steel bars in the bin. The adsorption position is in the middle of the multiple steel bars. Then, the lifting electromagnet adsorption mechanism 1.2 is lifted to a certain height, but not the high position. Due to the deformation of the steel bars, the middle part of the steel bars is lifted, forming a state where the middle is high and the two ends are low.

[0009] Step 2: Control the receiving channel steel 1.3.4 of the lifting telescopic receiving mechanism 1.3 to extend below the steel bars. Then, control the electromagnet of the lifting electromagnet adsorption mechanism 1.2 to be powered off, and the lifting electromagnet adsorption mechanism 1.2 rises to the high position. The lifting telescopic receiving mechanism 1.3 will receive the steel bars dropped from the lifting electromagnet adsorption mechanism 1.2. Then, control the lifting telescopic receiving mechanism 1.3 to retract, and control the crossbeam 1 to move synchronously towards the steel bar bin through the track walking structure device 2, requiring the position of the steel bars relative to the bin to remain unchanged, and transfer the multiple steel bars above the horizontal paving moving mechanism 1.4. Use the lifting telescopic receiving mechanism 1.3 and the horizontal paving moving mechanism 1.4 to jointly lift the middle part of the steel bars.

[0010] Step 3: Control the two groups of horizontal paving moving mechanisms 1.4 to move towards both ends of the crossbeam 1. The pneumatic telescopic receiving mechanism 1.5 at each corresponding position will extend in sequence. Finally, all the multiple groups of steel bars are supported by the lifting telescopic receiving mechanism 1.3 and the pneumatic telescopic receiving mechanism 1.5. The crossbeam 1 moves towards the horizontal feeding rack (an additional receiving device that cooperates with the magnetic adsorption feeding equipment and can also be paired with other different equipment) through the track walking structure device 2. Subsequently, after the receiving cylinder of the horizontal feeding rack extends to lift the steel bars, the transfer of the steel bars is completed.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present utility model.

[0040] Example 1, as Figure 1-2 shown, the steel bar magnetic adsorption feeding system includes a cross beam 1. A set of track walking structure devices 2 for walking along the corresponding ground track 3 are respectively installed at both ends of the cross beam 1. The two ground tracks 3 are parallel to each other and are both installed on the ground. A lifting electromagnetic adsorption mechanism 1.2 and a lifting telescopic material receiving mechanism 1.3 are installed in the middle of the cross beam 1. A set of horizontal material spreading and moving mechanisms 1.4 that can move along the length direction of the cross beam 1 are respectively arranged on both sides of the lifting electromagnetic adsorption mechanism 1.2. The cross beam 1 is a rectangular tubular structure, having a front side and a rear side arranged oppositely, and a top surface and a bottom surface arranged oppositely. A plurality of pneumatic telescopic material receiving mechanisms 1.5 are arranged at intervals along the length direction of the bottom surface of the cross beam 1.

[0041] This device is used to transfer the steel bars in the steel bar bin to the feeding side of the existing horizontal feeding rack. The specific operation is as follows.

[0042] The first step: Stack multiple steel bars to be transferred in the steel bar bin. First, control the crossbeam 1 to move to one side of the steel bar bin, then lower the lifting electromagnet adsorption mechanism 1.2 to the low position. The electromagnet of the lifting electromagnet adsorption mechanism 1.2 is energized, and the lifting electromagnet adsorption mechanism 1.2 is used to adsorb multiple adjacent steel bars in the bin. The adsorption position is in the middle of the multiple steel bars. Then, the lifting electromagnet adsorption mechanism 1.2 is lifted to a certain height, but not the high position. Due to the deformation of the steel bars, the middle parts of the steel bars are lifted, forming a state with the middle high and both ends low.

[0043] The second step: Control the receiving channel steel 1.3.4 of the lifting telescopic receiving mechanism 1.3 to extend below the steel bars. Then, control the electromagnet of the lifting electromagnet adsorption mechanism 1.2 to be powered off. The lifting electromagnet adsorption mechanism 1.2 rises to the high position. The lifting telescopic receiving mechanism 1.3 will receive the steel bars dropped from the lifting electromagnet adsorption mechanism 1.2. Then, control the lifting telescopic receiving mechanism 1.3 to retract, and control the crossbeam 1 to move towards the steel bar bin synchronously through the track walking structure device 2, requiring the position of the steel bars relative to the bin to remain unchanged. Transfer multiple steel bars above the horizontal paving moving mechanism 1.4, and use the lifting telescopic receiving mechanism 1.3 and the horizontal paving moving mechanism 1.4 to jointly lift the middle parts of the steel bars.

[0044] The third step: Control the two groups of horizontal paving moving mechanisms 1.4 to move towards both ends of the crossbeam 1. The pneumatic telescopic receiving mechanism 1.5 at each corresponding position will extend in sequence. Finally, all the multiple groups of steel bars are supported by the lifting telescopic receiving mechanism 1.3 and the pneumatic telescopic receiving mechanism 1.5. The crossbeam 1 moves towards the horizontal feeding rack (an additional receiving device cooperating with the magnetic adsorption feeding equipment, or other different equipment can also be matched) through the track walking structure device 2. Subsequently, after the receiving cylinder of the horizontal feeding rack extends to lift the steel bars, the transfer of the steel bars is completed.

[0051] The telescopic driven gear 1.3.8, the telescopic driving gear 1.3.6 and the channel steel guiding bearing 1.3.5 can jointly guide the material receiving channel steel 1.3.4. When the middle of the steel bar is lifted to form a state where the middle is high and the two ends are low, the speed reducer B1.3.3 drives the material receiving channel steel 1.3.4 to extend relative to the telescopic guiding frame 1.3.2 and transfer it below the steel bar. The control electromagnet 1.2.3 is powered off, and the steel bar is supported by the material receiving channel steel 1.3.4.
