Abstract
Description
Technical Field
[0001] This utility model relates to the field of bolt processing equipment technology, specifically a cooling device for bolt processing. Background Technology
[0002] A bolt is a type of fastener consisting of a head and a shank (a cylinder with external threads). It needs to be used with a nut to fasten two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated. Therefore, a bolted connection is a detachable connection.
[0003] To improve the strength and hardness of bolts, they need to be heat-treated during production. After heat treatment, the bolts are usually placed in water to cool down. When placing the bolts in water, all the bolts are usually poured into the water at once, which can easily cause the bolts to pile up together. The contact parts of the bolts are not fully in contact with the cooling water, resulting in poor cooling effect. Utility Model Content
[0004] To address the aforementioned shortcomings of the existing technology, this utility model provides a cooling device for bolt processing. The bolts are arranged in a single layer in each cooling frame, and multiple vertically arranged cooling frames divide the bolts into multiple layers, which can effectively prevent the bolts from stacking together, thereby increasing the contact area with water and improving the cooling effect on the bolts.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for bolt processing, comprising a water tank with an open top, four support rods on the top of the water tank, a top plate on the top of the four support rods, a telescopic cylinder on the top plate, the telescopic end of the telescopic cylinder penetrating through the top plate and connected to a first connecting plate at its end, four first limiting rods on the bottom of the first connecting plate, each first limiting rod having a groove, a slider vertically sliding in each groove, and a second connecting plate between the four sliders, the second connecting plate vertically... The system has four sliding rods, each with a limit block at its top. Four clearance holes are provided on the first connecting plate corresponding to the four limit blocks. A third connecting plate is provided at the bottom of the four sliding rods, with mounting grooves and multiple first water passage holes. Multiple cooling frames are vertically arranged within the mounting grooves. Each cooling frame has an open top and multiple second water passage holes on its side and bottom walls. Four clearance grooves are provided on the bottom edge of each cooling frame, with the top of the lower cooling frame's side wall embedded in the clearance groove of the upper cooling frame.
[0006] Preferably, a drain pipe is connected to the side wall of the water tank near the bottom, and a drain valve is provided on the drain pipe.
[0007] Preferably, the bottom of the top plate is provided with multiple second limiting rods, which pass through the first connecting plate and are slidably connected to the first connecting plate.
[0008] Preferably, the first connecting plate has a plurality of first exhaust holes, and the second connecting plate has a plurality of second exhaust holes at positions corresponding to the plurality of first exhaust holes.
[0009] Preferably, the bottom of the second connecting plate is provided with a positioning groove, and the upper cooling frame sidewall can be embedded into the positioning groove.
[0010] Preferably, each of the cooling frames is provided with a pair of handles on both sides.
[0011] This utility model provides a cooling device for bolt processing, which has the following beneficial effects:
[0012] 1. In this utility model, the bolts are arranged in a single layer in each cooling frame. The multiple vertically arranged cooling frames divide the bolts into multiple layers, which can effectively prevent the bolts from stacking together, thereby increasing the contact area with water and improving the cooling effect on the bolts.

A second connecting plate 7 is positioned between the four sliders 13. Four sliding rods 8 are vertically slidably mounted on the second connecting plate 7. A limiting block 8-1 is mounted on the top of each sliding rod 8. Four clearance holes 5-2 are provided on the first connecting plate 5 corresponding to the positions of the four limiting blocks 8-1. A third connecting plate 9 is mounted on the bottom of the four sliding rods 8. An installation groove 9-2 and multiple first water passage holes 9-1 are provided on the third connecting plate 9. Multiple cooling frames 10 are vertically arranged inside the -2. Each cooling frame 10 has an opening at the top and multiple second water passage holes 10-1 on its side and bottom walls. Four clearance grooves 10-2 are provided on the bottom edge of each cooling frame 10. The top of the side wall of the lower cooling frame 10 is embedded into the clearance groove 10-2 of the upper cooling frame 10. A drain pipe 1-1 is connected to the side wall of the water tank 1 near the bottom. A drain valve 1-2 is provided on the drain pipe 1-1. Multiple second limiting rods 12 are provided at the bottom of the top plate 3. The second limiting rods 12 pass through the first connecting plate 5 and are slidably connected to the first connecting plate 5. Multiple first vent holes 5-1 are provided on the first connecting plate 5. Multiple second vent holes 7-1 are provided on the second connecting plate 7 at the positions corresponding to the multiple first vent holes 5-1. A positioning groove 7-2 is provided at the bottom of the second connecting plate 7. The side wall of the upper cooling frame 10 can be embedded into the positioning groove 7-2. A pair of handles 11 are provided on both sides of each cooling frame 10.
[0021] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:
[0022] In this utility model, the telescopic cylinder 4 is connected to an external electrical control system via a wire. The above equipment and connection method are existing technologies and will not be described in detail here.
[0023] According to the instruction manual Figure 1-4It can be seen that the support rods 2 of this utility model are four in number and are set at the four corners of the top of the water tank 1. The top plate 3 has through holes, and the telescopic end of the telescopic cylinder 4 passes through the through holes. The telescopic cylinder 4 can be hydraulically driven or motor driven. When cooling the bolts, water is first injected into the water tank 1, and the bolts are placed in batches in the cooling frames 10. The bolts are distributed in a single layer in each cooling frame 10. Then, one of the cooling frames 10 is placed on the third connecting plate 9, so that the bottom of the cooling frame 10 is embedded in the mounting groove 9-2 on the third connecting plate 9. Then, the other cooling frames 10 are vertically installed on the bottom cooling frame 10 in sequence. The top of the side wall of each cooling frame 10 is embedded in the clearance groove 10-2 opened at the bottom of the upper cooling pipe, so that the bolts are arranged in multiple layers. The telescopic cylinder 4 set on the top plate 3 is activated. The telescopic end of the telescopic cylinder 4 drives the connected first connecting plate 5 to move vertically downward. The first connecting plate 5 drives multiple first limiting rods 6 to move vertically downward. The multiple first limiting rods 6 cause multiple Slider 13 moves vertically downwards, multiple sliders 13 drive the second connecting plate 7 to move vertically downwards, the second connecting plate 7 drives multiple sliding rods 8 to move vertically downwards, the multiple sliding rods 8 drive the third connecting plate 9 to move vertically downwards, the third connecting plate 9 drives multiple cooling frames 10 to move vertically downwards, the multiple cooling frames 10 drive the bolts to move downwards. When the third connecting plate 9 comes into contact with water, it will be buoyed by the water, which will cause multiple sliding rods 8 to move vertically upwards on the second connecting plate 7. When the second connecting plate 7 abuts against the uppermost cooling frame 10, the slider 13 will move upwards in the slide groove 6-1. When the first connecting plate 5 abuts against the second connecting plate 7, it can press all the bolts into the water. At this time, the limiting block 8-1 and the sliding rods 8 pass through the clearance hole 5-2 opened on the first connecting plate 5. After cooling for a period of time, the telescopic end of the telescopic cylinder 4 retracts, driving multiple cooling frames 10 to move vertically upwards to the position before cooling. Personnel remove multiple cooling frames 10 in sequence to complete the cooling operation.
[0024] One possible implementation is to open the drain valve 1-2 on drain pipe 1-1, which would allow the cooled water to be discharged.
[0025] One possible implementation is to use multiple second limiting rods 12 to limit the first connecting plate 5, preventing the first connecting plate 5 from shifting when it moves vertically.
[0026] One possible implementation is that when the bolt is cooled in water, water vapor is generated when the heat-treated bolt comes into contact with water, and the water vapor is discharged from multiple second vent holes 7-1 opened on the second connecting plate 7 and multiple first vent holes 5-1 opened on the first connecting plate 5.
[0027] One possible implementation is that when the second connecting plate 7 contacts the uppermost cooling frame 10, the top of the uppermost cooling frame 10 is embedded into the positioning groove 7-2, making the multiple cooling frames 10 more stable when in water.
[0028] One possible implementation is that when personnel remove the cooling box 10, they can do so via the handle 11, which facilitates operation.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
