Technical Field

[0001] The utility model relates to the field of springs, in particular to a steel bar cutting device for spring production and processing. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. A part made of elastic material deforms under the action of external force and returns to its original shape after the external force is removed. It is also called a "spring". Steel bars are required in the production and processing of springs. When making springs, the steel bars need to be cut to size to facilitate the subsequent production and processing of the springs.

[0030] The pressing tool assembly 7 is installed on both sides of the connecting plate 4 and is used to limit and compact the steel bar body 9;

[0031] The adjusting mechanism 12 is installed on one side of the frame 1 and is used to adjust the length of the blocking steel bar body 9. When the steel bar body 9 is placed in the placement rack 8, the hydraulic cylinder 3 switch is turned on to push the connecting plate 4 and the cutting knife 6 down. During the descent, the pressure plate 705 and the anti-slip pad 706 are pressed against the top of the steel bar body 9. When the whole continues to descend, the telescopic rod 703 above the pressure plate 705 is extended and retracted in the fixed sleeve 701, and the internal pressure spring 704 is used to squeeze the telescopic rod 703 and the pressure plate 705 below, so that the pressure plate 705 is pressed more tightly against the top of the steel bar body 9, thereby avoiding shaking when the steel bar body 9 is cut.

[0032] like Figure 1 and Figure 2As shown, both sides of the inner surface of the frame 1 are provided with slide grooves 2, and sliders 5 are fixedly installed on both sides of the connecting plate 4. The slide grooves 2 and the sliders 5 are used in conjunction with each other. When the connecting plate 4 is pushed by the hydraulic cylinder 3, it moves up and down in the frame 1, and the sliders 5 on both sides are used to slide in the slide grooves 2 in the frame 1 to play a stabilizing role.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, the pressure plate 705 is symmetrically arranged with respect to the central axis of the connecting plate 4, and an anti-skid pad 706 is pasted at the bottom of the pressure plate 705. Two groups of pressure plates 705 are arranged, one on each side of the cutting knife 6, so as to compact the two sides of the cutting position of the steel bar body 9, thereby improving the stability of the steel bar body 9. At the same time, the anti-skid pad 706 improves the anti-skid property, and also avoids scratches on the outside of the steel bar body 9 caused by large compaction force.

When the connecting plate 4 rises and falls, it drives the cutting knife 6 and the pressing tool assembly 7 below to descend, and the pressing tool assembly 7 first contacts the upper two sides of the steel bar main body 9, and when the pressing plate 705 and the anti-slip soft pad 706 are pressed on the steel bar main body 9, the cutting knife 6 It needs to continue to descend for cutting, so that the telescopic rod 703 above the pressure plate 705 can be extended and retracted in the fixed sleeve 701, and the internal pressure spring 704 is used to squeeze the telescopic rod 703 and the pressure plate 705 below, so that the pressure plate 705 is pressed more tightly above the steel bar body 9, thereby avoiding shaking when the steel bar body 9 is cut. After that, the cutting knife 6 contacts the steel bar body 9 for cutting. After cutting, the hydraulic cylinder 3 switch is turned off, and the overall cutting knife 6 and the press assembly 7 are raised and lowered to the original position. The cut steel bar body 9 loses the compaction of the pressure plate 705, and will automatically fall onto the buffer discharge plate 11 for discharge. Next, continue to cut the next steel bar body 9 through the previous steps. Finally, when the device is not used, cut off the external power supply. In this way, the use process of the steel bar cutting device for spring production and processing is completed.
