Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-5 A heat treatment device for producing high-torque nuts includes a heat treatment chamber 1. A guide groove 19 is provided at the bottom of the inner wall of the heat treatment chamber 1. A discharge port is provided through the right side of the heat treatment chamber 1 and is connected to the guide groove 19. A flap 17 is rotatably installed inside the heat treatment chamber 1. A set of connecting shafts 24 are fixedly installed on both the front and rear sides of the flap 17. A first support hole is provided on the rear side of the inner wall of the heat treatment chamber 1, and a second support hole is provided through the front side of the inner wall. The connecting shaft 24 located on the rear side of the flap 17 is rotatably installed in the first support hole, and the connecting shaft 24 located on the front side of the flap 17 passes through the second support hole and is connected to a worm gear 2. A worm 22 is meshed at the top of the worm gear 2. A handwheel 23 is fixedly installed on the left side of the worm 22. Rotating the handwheel 23 drives the worm 22 to rotate, which in turn drives the worm gear 2 to rotate. The worm gear 2 drives the flap 17 through the connecting shafts 24. Flipping downwards, a concave seat 3 is fixedly installed on the right side of the heat treatment chamber 1. A baffle 31 is rotatably installed inside the concave seat 3. A through hole is opened on the front side of the baffle 31. A rotating shaft 33 is rotatably installed in the through hole. A torsion spring 34 is fixedly installed between the rotating shaft 33 and the through hole. The rotating shaft 33 is fixedly installed in the concave seat 3. A heat insulation pad 32 is fixedly installed on the left side of the baffle 31. The heat insulation pad 32 is in contact with the right side of the heat treatment chamber 1. The heat insulation pad 32 is located on the right side of the discharge port of the heat treatment chamber 1. The torsion spring 34 uses its own elasticity to drive the heat insulation pad 32 through the baffle 31 to close the discharge port of the heat treatment chamber 1. This can reduce the heat loss inside the heat treatment chamber 1 during heat treatment, thereby ensuring the heat treatment efficiency. Two sets of support sleeves 21 are evenly rotatably installed on the outer ring of the worm gear 22. The two sets of support sleeves 21 are evenly fixedly installed on the front side of the heat treatment chamber 1, and the worm gear 22 is supported to rotate through the support sleeves 21.
[0022] A set of sliding grooves is provided on both the front and rear sides of the inner wall of the heat treatment chamber 1, and the sliding grooves run through the left side of the heat treatment chamber 1. A support plate 16 is slidably installed inside the heat treatment chamber 1. The front and rear sides of the support plate 16 are respectively located in the two sets of sliding grooves. A placement groove is provided on the top of the support plate 16, and the placement groove runs through the right side of the support plate 16. A warning strip 18 is embedded in the inner wall of the placement groove. Nuts are evenly placed in the placement groove. The position of the nuts in the placement groove is restricted by the warning strip 18. The space between the warning strip 18 and the left side of the inner wall of the placement groove is the movement space of the flip plate 17. Nuts cannot be placed in this movement space. The flip plate 17 is located above the support plate 16 and corresponds to the placement groove. The support plate 16 is located above the guide groove 19. A door 11 is fixedly installed on the left side of the heat treatment chamber 1. A set of latches 15 are fixedly installed on both the front and rear sides of the door 11 and the heat treatment chamber 1. Two sets of connecting plates 13 are evenly fixedly installed at the bottom of the door 11. A guide rod 14 is fixedly installed on the right side of the connecting plate 13. Two sets of guide holes are evenly opened on the left side of the heat treatment chamber 1. After the nuts are placed, the door 11 is pushed to the right by the handle 12, which moves the support plate 16 along the slide groove into the heat treatment chamber 1. Then, the door 11 is fixed to the left side of the heat treatment chamber 1 by the latches 15. At this time, the nuts are heat treated by the heat treatment chamber 1. The heat treatment chamber 1 is a relatively mature heat treatment equipment. Its working principle will not be described in detail here. The guide rod 14 is slidably installed in the guide hole.
[0023] Working principle: Nuts are evenly placed in the placement slot. The position of the nuts in the placement slot is restricted by the warning strip 18. The space between the warning strip 18 and the left side of the inner wall of the placement slot is the movement space of the flip plate 17. Nuts cannot be placed in this movement space. After the nuts are placed, the handle 12 is pushed to the right to move the box door 11, which moves the tray 16 along the slide to the heat treatment box 1. Then, the box door 11 is fixed to the left side of the heat treatment box 1 by the buckle 15. At this time, the nuts are heat treated by the heat treatment box 1. The heat treatment box 1 is a relatively mature heat treatment equipment. Its working principle will not be described in detail here. The torsion spring 34 uses its own elasticity to drive the heat insulation pad 32 through the baffle 31 to close the discharge port of the heat treatment box 1. This can reduce the heat loss inside the heat treatment box 1 during heat treatment, thereby ensuring the heat treatment efficiency.
[0024] After heat treatment is completed, unlock the buckle 15, turn the handwheel 23 to drive the worm gear 22 to rotate, and the worm gear 22 drives the worm wheel 2 to rotate. The worm wheel 2 drives the flip plate 17 to flip down through the connecting shaft 24 into the movement space between the warning strip 18 and the left side of the inner wall of the placement slot. At this time, the left side of the flip plate 17 is in contact with the left side of the inner wall of the placement slot. Then, pull the door 11 by the handle 12 to drive the tray 16 to slide to the left. At this time, the nut in the placement slot will move to the left along with the tray 16. However, the nut will not be able to move to the left due to the obstruction of the flip plate 17. Therefore, the nut will move to the left with the tray 16 and fall from the placement slot onto the guide groove 19. It will then be discharged from the outlet of the heat treatment box 1 along the guide groove 19. During this process, the nut will come into contact with the heat insulation pad 32. The nut uses its own weight to overcome the weight of the heat insulation pad 32 and the baffle 31 and the elastic force of the torsion spring 34 to push the heat insulation pad 32 and the baffle 31 open, thereby achieving the effect of automatic material discharge.
