Description

Technical Field

[0001] The invention relates to the field of fastener processing, and in particular to fastener production and processing equipment and a production process. Background Art

[0002] Fasteners are mechanical components that can mechanically fix or bond two or more components together. There are many varieties and specifications of fasteners, and there are suitable fasteners for different usage scenarios. Among them, U-bolt connectors require straightening, cutting, thread rolling and bending of metal bars during processing and production;

[0003] The prior art patent CN111660076B discloses a fastener feeding device, including a conveying device and two processing devices. Through a series of transmission mechanisms, a driving motor first drives a supply plate 2 connected to the lower end of the screw sleeve to push the blank onto the feed bottom plate, and then a feed plate 1 connected to a rotating shaft pushes the blank into the processing device, thereby completing the automatic feeding of the blank. The device has a simple structure, and all feeding work only requires one driving motor to drive it. It is cheap, liberates labor, reduces the labor intensity of the staff, and greatly improves the processing and production efficiency of fasteners. It accurately feeds the fastener bars to be processed through the cooperation between various mechanisms, but its function is relatively single. When processing U-bolt fasteners, it is necessary to chamfer both ends of the blank and then perform thread rolling.

[0018] A fastener production and processing process, the fastener production and processing process is applied to the above-mentioned fastener production and processing equipment, comprising the following steps:

[0019] Step 1: The fastener blanks are continuously fed to the upper end of the processing table through the feeding table. Under the limiting blocking effect of the limiting rubber strip, a number of fastener blanks are laid flat on the feeding table and the processing table, and are kept horizontally positioned under the effect of the baffles on both sides;

[0020] Step 2: When the telescopic control cylinder pushes the horizontal control plate to descend, a plurality of selected push plates first contact the middle of the two fastener blanks close to the limiting rubber strips through the tip, and then the fastener blanks in contact with the limiting rubber strips are pushed over the limiting rubber strips by the inclined surface of the selected push plates, and then further pushed to make them fall into the positioning placement groove of the customized placement plate.

At this time, the selection push plate lifts the L-shaped control plate through the strong magnetic suction block, and then the L-shaped control plate ejects the fastener blank out of the positioning groove through a number of ejector rods and stably falls from the blanking inclined position of the processing table into the next thread rolling process, completing the intermittent processing blank feeding.

On the basis of independently selecting the blanks required for processing, the ends of the fed blanks can be chamfered, thereby reducing the tediousness of multi-station and multi-process processing and improving the processing efficiency of U-bolts.

[0058] Step 2: When the telescopic control cylinder 14 pushes the horizontal control plate 15 to descend, the selected push plates 17 first contact the middle of the two fastener blanks 8 close to the limiting rubber strips 19 through the tip, and then the fastener blank 8 in contact with the limiting rubber strips 19 is pushed over the limiting rubber strips 19 by the inclined surface of the selected push plates 17, and then further pushed to fall into the positioning placement groove 35 of the customized placement plate 7. After the fastener blank 8 falls into the positioning placement groove 35, the selected push plates 17 continue to descend. At this time, the two inclined transmission rods 32 of the horizontal control plate 15 further push the horizontal transmission plate 31 and the processing seat 21 to approach the fastener blank 8, and the end of the processing seat 21 passes over the connecting sleeve 20 and surrounds the fastener blank 8, and the chamfered grinding groove 27 of the grinding knife 26 contacts the end of the fastener blank 8;

[0059] Step 3: The air inlet connector 24 is connected to the high-pressure gas, and the high-pressure gas drives the installation drum 22 through the blade 23 to control the grinding knife 26 to rotate in height. At this time, the wear-resistant elastic rubber pad of the push plate 17 is selected to press and fix the fastener blank 8 and the customized placement plate 7, and the grinding knife 26 grinds the end of the fastener blank 8. Then, as the push plate 17 continues to descend, the wear-resistant elastic rubber pad is compressed and deformed, and the processing seat 21 and the grinding knife 26 further move toward the position of the fastener blank 8 to complete the end grinding operation of the fastener blank 8;

[0060] Step 4: After the high-pressure gas enters the air flow slot, it enters the diverter slot 28 through a plurality of transmission slots 29, and then is blown obliquely from a plurality of cleaning holes 30 toward the grinding processing positions of the grinding knife 26 and the fastener blank 8, and the metal or abrasive dust generated by wear is blown toward the end cover 33 of the processing seat 21 through the dust slot 36, and is collected and processed centrally through the environmental protection collection slot 34;

[0061] Step 5: When the end processing of a single fastener blank 8 is completed, the telescopic control cylinder 14 controls the horizontal control plate 15 and the selection push plate 17 to rise. At this time, the selection push plate 17 lifts the L-shaped control plate 9 through the strong magnetic suction block 18, and then the L-shaped control plate 9 ejects the fastener blank 8 out of the positioning placement groove 35 through a number of ejector rods 10 and stably falls from the blanking slope 12 of the processing table 3 into the next thread rolling process, completing the intermittent processing blank feeding.
