Description

Technical Field

[0001] This invention relates to the field of drill bit processing technology, specifically to an automatic feeder and normalizing device for drill bits. Background Technology

[0002] As core tools in mining, tunneling, and geological exploration, the performance of drill bits directly affects operational efficiency and safety. Normalizing is a critical process in drill bit manufacturing. By controlling the heating temperature, holding time, and cooling rate, the internal grains of the drill bit can be refined, forging stress can be eliminated, and its hardness, toughness, and fatigue resistance can be significantly improved. This is an important guarantee for extending the service life of drill bits and ensuring operational safety.

[0003] Currently, normalizing of drill bits largely relies on manual labor or semi-automated equipment, which presents the following significant problems: First, the loading, feeding, and unloading processes require manual intervention, resulting in high labor intensity, low production efficiency, and the possibility of inaccurate drill bit positioning due to human error, affecting the uniformity of heating and cooling. Second, traditional normalizing equipment often uses single-station intermittent heating, making it difficult to precisely control the dwell time of the drill bit in the furnace, easily leading to localized overheating or undercooling, resulting in poor performance consistency after normalizing. Third, the cooling process mostly relies on natural air cooling or simple wind cooling, making it impossible to dynamically adjust the cooling rate according to the material and specifications of the drill bit, easily causing thermal stress concentration, resulting in drill bit deformation or even cracking. Fourth, there is a lack of linkage control between the various processes (loading-feeding-heating-cooling-unloading), poor equipment coordination, and difficulty in achieving continuous production, which restricts large-scale application.

[0004] With the rapid development of industrial automation technology, the demand for efficient, stable, and intelligent normalizing equipment is becoming increasingly urgent for drill bit manufacturers. Designing a normalizing device that integrates automatic feeding, continuous feeding, precise heating, controllable air cooling, and automatic unloading to solve problems such as high reliance on manual labor, low temperature control accuracy, unstable cooling effect, and low production efficiency in traditional processes has become a critical technological bottleneck that needs to be overcome in the drill bit manufacturing industry.

The pushing device 604 includes a reciprocating push rod 801, a top material block 802, and a U-shaped movable slide 803. Several U-shaped movable slides 803 are fixedly connected to the inner wall of the storage rack 602 on one side of the slot. The top material block 802 is slidably connected in the U-shaped groove of the U-shaped movable slide 803. Sliding guide grooves 804 are opened on both sides of the top material block 802. Sliding guide strips 805 are fixedly connected to the inner side of the U-shaped movable slide 803. The sliding guide strips 805 are all slidably connected in the sliding guide grooves 804. A sliding guide hole is opened at the bottom of the U-shaped movable slide 803. The reciprocating push rod 801 is slidably connected in the sliding guide hole. One end of the reciprocating push rod 801 is connected to the top material block. 802 is fixedly connected, and the other end of the reciprocating push rod 801 passes through the sliding guide hole and is rotatably connected to the connecting rod 704; in addition, the second material guiding device 606 includes a second mounting frame 901, a second pulley 902, a second conveyor belt 903, a second rotating shaft block 904, and a second pushing block 905. Two sets of symmetrical second mounting frames 901 are fixedly connected to the feeding mounting frame 201 located on one side of the automatic feeding device 1. Two sets of symmetrical second pulleys 902 are rotatably connected to the second mounting frame 901. The two sets of second pulleys 902 are mutually connected through the second conveyor belt 903. Several evenly spaced second rotating shaft blocks 904 are fixedly connected to the second conveyor belt 903. Each second rotating shaft block 904 is rotatably connected to a second pushing block 905.A second linkage shaft 906 is fixedly connected to the shaft of the second pulley 902 located on the same side. One end of the second linkage shaft 906 passes through the feeding device 2 and is connected to the second transmission mechanism. The second transmission mechanism includes a second transmission wheel 1001, a rotating shaft 1002, a third worm gear 1003, a third worm 1004, a seventh sprocket 1005, and an eighth sprocket 1006. The rotating shaft 1002 is rotatably connected to the feeding device 2 located at one end of the automatic feeding device 1. The second transmission wheel 1001 is fixedly connected to one end of the rotating shaft 1002. The second transmission wheel 1001 is also connected to the linkage wheel 206 on the same side. The third worm 1004 is provided on the rotating shaft 1002, and the third worm 1004 is meshed with the third worm gear 1003. The third worm gear 1003 is rotatably connected to the feeding device 2.

The eighth sprocket 1006 is fixedly connected to one end of the second linkage shaft 906. In use, firstly, the drill bits to be normalized are neatly stacked according to length in the storage trough at the upper end of the storage rack 602. The bottom of the storage trough is inclined towards the trough opening. Due to the inclination of the trough bottom and the weight of the drill bits themselves, the drill bits roll downwards to the trough opening and are blocked by the baffle plate 603. Then, the feeding device 2 is started, driving the fifth sprocket 701 to rotate. The fifth sprocket 701 drives the sixth sprocket 702 to rotate via a chain belt. 2. The rotating disk 703 on the same axis rotates, causing the rotating rod to move in a circular motion. Simultaneously, one end of the connecting rod 704 rotates, and the other end of the connecting rod 704 drives the reciprocating push rod 801 to move up and down reciprocally. The other end of the reciprocating push rod 801 drives the top block 802 to reciprocate within the U-shaped sliding frame 803. During this process, when the top block 802 is at its lowest point, the drill bit abuts against the baffle plate 603, and the drill bit is directly below the top block 802. Then, as the rotating disk 703 continues to rotate, the connecting rod 704 drives the reciprocating push rod 801 to move upwards. The reciprocating push rod 801 drives the top block 802 to move upwards, thereby driving the drill bit above to move upwards. When the drill bit exceeds the height of the baffle plate 603, it causes... The drill bit falls over the baffle plate 603 and out of the slot. It then lands on the second guide frame 605. Simultaneously, the linkage wheel 206 in the feeding device 2 drives the second transmission wheel 1001 to rotate via a belt. The second transmission wheel 1001 drives the rotating shaft 1002 to rotate, which in turn drives the third worm gear 1004 to rotate. The third worm gear 1004 drives the third worm wheel 1003 to rotate, which in turn drives the seventh sprocket 1005 on the same coaxial side to rotate. The seventh sprocket 1005 drives the eighth sprocket 1006 to rotate via a chain belt, which in turn drives the second linkage shaft 906 to rotate. The second linkage shaft 906 simultaneously drives two sets of second pulleys 902 to rotate, which in turn drive the second conveyor belt 903.The second transmission belt drives the second rotating shaft block 904, which in turn drives the second pusher block 905. This pusher block 905 then moves the drill bit on the second guide frame 605 until it falls onto the guide roller 203. A stop bar 607 on the other side of the guide roller 203 prevents the drill bit from falling off. Thus, the drill bit moves along the feeding mounting frame 201 via the guide roller 203.

[0045] Please see Figures 4-6 The feeding device 2 includes a feeding mounting frame 201, a rotating shaft 202, a guide roller 203, a drive gear 204, and a transmission gear 205.

Several sets of rotating shafts 202 have transmission gears 205 fixedly connected to one end, and the transmission gears 205 are connected to the drive gear 205 via chains. The moving gears 204 are interconnected for transmission, and the driving gear 204 is fixedly connected to the end of the driving motor 207. The driving motor 207 is fixedly connected inside the feeding mounting frame 201. In specific operation, the driving motor 207 drives the driving gear 204 to rotate, and the driving gear 204 drives the transmission gear 205 to rotate through the chain belt. The transmission gear 205 drives the rotating shaft 202 on the corresponding side to rotate. The other end of the rotating shaft 202 drives all the rotating shafts 202 to rotate synchronously through the linkage wheel 206. The rotating shaft 202 drives the guide roller 203 to rotate, thereby driving the drill bit to the direction of the automatic feeding device 3 through the guide roller 203.
