Description

Technical Field

[0001] This utility model relates to the technical field of quenching and cooling devices, specifically a quenching and cooling device for the production of self-drilling screws. Background Technology

[0002] Self-drilling screws, also known as self-drilling screws, are screws with a self-drilling head at the front end. Compared with ordinary screws, self-drilling screws have higher pull-out strength and holding strength, and will not loosen even after being assembled for a long time. The quenching and cooling device used in the production of self-drilling screws plays an important role in the production of self-drilling screws, which helps to improve production efficiency and product quality.

[0003] Referring to patent application CN221720867U, a quenching and cooling device for producing self-drilling screws is disclosed, belonging to the field of self-drilling screw production technology. It includes a fixed box, with a fixed frame on the inner wall of the fixed box, and supporting cooling pipes on the inner wall of the fixed frame. Multiple supporting cooling pipes are connected to vortex cooling pipes at both ends. A cooling assembly is installed at the top of the fixed box cavity. A rotating motor drives a spiral conveyor rod to rotate, which in turn moves multiple self-drilling screws evenly and slowly. This allows the screws to be cooled by multiple spray nozzles on the inner wall of a water tank, thereby improving the contact time and uniformity between the cooling medium and the screws. After spraying, the cooling medium is filtered through a filter and circulated by a water pump, reducing the cost of screw quenching and cooling, reducing the waiting time for cooling water to cool down, and improving the efficiency of quenching and cooling.

[0004] As shown in the prior art, in the prior art, the self-drilling screw passes through a fixed box, and is cooled by a water tank spraying cold water onto the screw. Then the screw falls onto the filter screen. As the screw is continuously conveyed, screws tend to accumulate on the filter screen at the outlet of the fixed box. The screws are unevenly distributed on the filter screen, and the filter screen space is not fully utilized, resulting in a high feeding frequency. Furthermore, since the screws are continuously conveyed, only one fixed box receives the screws, and its cooling efficiency is low.

[0005] Therefore, it is necessary to provide a quenching and cooling device for the production of self-drilling screws to solve the above-mentioned technical problems. Utility Model Content

[0027] 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.

[0028] This utility model provides two technical solutions:

[0029] Figures 1 to 4 The first embodiment is shown: a quenching and cooling device for the production of self-drilling screws, including a box body 1, a feeding port 2 at the top of the box body 1, a discharging port 3 on one side of the box body 1, a water storage tank 4 at the bottom inside the box body 1, a filter frame 5 slidably connected to the inner wall of the box body 1 corresponding to the position of the discharging port 3, and a plurality of nozzles 6 are installed at equal intervals above the filter frame 5 on the inner wall of the box body 1, and the plurality of nozzles 6 are connected by water pipes 7.

[0030] Inside the housing 1, there are symmetrically installed mesh cylinders 8 that receive the screws entering the housing 1. Inside the mesh cylinders 8, there is a rotating auger conveyor 9. A rotating assembly is installed on the housing 1 to make the mesh cylinders 8 revolve inside the housing 1 and at the same time make the auger conveyor 9 rotate. The rotating assembly is used to make the screws coming out of the mesh cylinders 8 evenly spread on the filter frame 5.

[0031] The rotating assembly includes an internal gear 10 symmetrically fixed above the inner wall of the housing 1. The inner wall of the internal gear 10 is connected to a small gear 11 meshing above the two mesh cylinders 8. The small gear 11 is hollow and has connecting rods 18 fixed at equal intervals on its inner wall. The end of the connecting rod 18 away from the small gear 11 is fixed to the upper end of the auger conveyor 9. The connecting rod 18 is inclined.

[0032] A rotating shaft 12 is rotatably connected to the upper part of the inner wall of the box 1. A motor 13 is fixed to the top of the box 1. The output end of the motor 13 is fixed to the upper end of the rotating shaft 12. A connecting plate 14 is fixed to the side of each of the two mesh cylinders 8 near the rotating shaft 12. The end of the connecting plate 14 near the rotating shaft 12 is fixed to the outer wall of the rotating shaft 12.

[0033] Driven by the rotating component, the mesh cylinder 8 revolves while the auger conveyor 9 evenly lays the screws from the bottom of the mesh cylinder 8 onto the filter frame 5, avoiding the problem of screws accumulating and unevenly distributing on the filter screen. This design makes full use of the filter screen space, reduces the feeding frequency, and improves production efficiency.

[0034] Figures 2 to 5 The second embodiment is shown, and the main difference from the first embodiment is that: a condenser tube 15 is fixed inside the box 1 below the filter frame 5; a slide rail 16 is symmetrically fixed inside the box 1 at the position corresponding to the feed port 3, and the bottom of the filter frame 5 is slidably connected to the inner wall of the slide rail 16; a water pump 17 is fixed on the lower side wall of the box 1, the water inlet of the water pump 17 is connected to the inside of the water storage tank 4 through the first pipe, and the water outlet of the water pump 17 is connected to the water pipe 7 through the second pipe.

[0035] A condenser pipe 15 is fixed below the filter frame 5, which can further cool the cooling water and improve the cooling efficiency; the cooling water in the water storage tank 4 is circulated to the nozzle 6 by the water pump 17, realizing the recycling and saving of cooling water.

[0036] Working principle:

[0037] The drilled screw enters the device through the top feed port 2 of the housing 1. After the screw is received by one of the mesh cylinders 8, the motor 13 drives the rotating shaft 12 to rotate, causing the two mesh cylinders 8 to start rotating around the inner ring of the internal gear 10. Since the mesh cylinder 8 is rotatably connected to the auger conveyor 9, and the upper end of the auger conveyor 9 is fixed with a small gear 11, when the rotating shaft 12 rotates, the small gear 11 is driven by the internal gear 10 to rotate, causing the auger conveyor 9 to rotate accordingly, transporting the screws in the mesh cylinder 8 downward one by one until the screws in the mesh cylinder 8 fall into the filter frame 5.

[0038] During the downward transport of screws inside the mesh cylinder 8, the nozzles 6 inside the housing 1 spray and cool the screws inside the mesh cylinder 8. The screws are transported and cooled one by one by the auger conveyor 9 to ensure the cooling effect. Since the mesh cylinder 8 rotates around the inner ring of the internal gear 10 and transports the screws downward at the same time, the screws can be evenly laid on the filter frame 5. Setting two mesh cylinders 8 is to facilitate the switching of work positions to receive the screws entering the housing 1 and improve the cooling efficiency.

[0039] During the process of the screw being conveyed by the auger conveyor 9 inside the mesh cylinder 8, it can be sprayed evenly to achieve uniform cooling of the screw; the sprayed water flows through the filter frame 5 and then contacts the condenser pipe 15 to achieve cooling of the water flow. Subsequently, the water flows into the water storage tank 4, and the water pump 17 transports the water in the water storage tank 4 back to the water pipe 7 to be sprayed out by the nozzle 6, realizing the recycling of water resources.

[0040] The cooled self-drilling screws on the filter frame 5 can be removed by pulling the filter frame 5 out of the slide rail 16.
