Description

Technical Field

[0001] The utility model relates to the technical field of bolt annealing, in particular to annealing equipment for bolt processing. Background Art

[0002] A bolt is a mechanical part, a cylindrical threaded fastener equipped with a nut. It is a type of fastener consisting of a head and a screw. It needs to be matched with a nut to fasten two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated. Therefore, the bolt connection is a detachable connection. During the processing of stainless steel bolts, it is necessary to anneal them. Annealing is a metal heat treatment process that refers to slowly heating the metal to a certain temperature, maintaining it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce the hardness and improve machinability.

[0003] Please refer to an annealing device for bolt processing disclosed in announcement number CN214830532U. In this patent, it is proposed that "through the mutual cooperation between structures such as cross bars, placement rollers, threaded holes, gears and gear rods, the bolts that need to be annealed can be fixed through the threaded holes on the placement rollers. When the gear rod drives the cross bar to rotate through the gears, the cross bar can drive the bolts to rotate through the placement rollers, so that all the bolts on the placement rollers can be heated. Through the mutual cooperation between structures such as heating plates, blowers, air pipes, rectangular blocks, vertical plates and nozzles, the gas can be evenly sprayed out through the blowers and nozzles." However, the bolt annealing devices in the prior art all place the screws horizontally, which can easily cause problems such as uneven annealing and a small number of screws placed. Therefore, this application proposes another technical solution to solve this problem. Utility Model Content

[0030] In this embodiment, the adjusting and moving mechanism includes an annealing box body 2 fixedly installed on the top of the fixed base 1, and the annealing box body 2 is used to anneal the internal bolts. The annealing box body 2 is composed of a blower, a heating plate, an air outlet pipe and a nozzle. First, the heating plate is used for heating, and then the blower is started to exhaust air from the heating plate, so that hot air can be blown out and blown out through the air outlet pipe and the nozzle, so that the bolts can be heated by the ejected gas.

[0031] In this embodiment, the heat-insulating door 3 movably connected to the front side of the annealing box body 2 helps to use the heat-insulating door 3 to close one side of the annealing box body 2, so that the entire annealing box body 2 enters a relatively closed environment. Two slide rails 4 are fixedly installed on the top of the fixed base 1, and two installation grooves are opened on the top of the fixed base 1. The slide rails 4 are fixedly connected to the fixed base 1 through the installation grooves, which helps to install and fix the slide rails 4.

The slider 5 is slidably connected to the slide rail 4 through the slide groove 401, which helps the slider 5 to slide inside the slide rail 4. A sealing block corresponding to the slide rail 4 is provided at the bottom of the heat insulation door 3, and the sealing block is adapted to the slide groove 401, which helps to close the slide rail 4 when closing.

[0033] In this embodiment, the mounting base 6 fixedly mounted on the top of the slider 5 and the rotating motor 7 fixedly mounted inside the mounting base 6 facilitate the installation and fixation of the rotating motor 7. The rotating rod 8 fixedly mounted on the output shaft of the rotating motor 7 helps the rotating motor 7 to drive the rotating rod 8 to rotate and move. The placing plate 9 movably mounted on the outside of the rotating rod 8 helps the rotating rod 8 to drive the placing plate 9 to rotate. A plurality of placing grooves 901 compatible with the bolts are opened on the top of the placing plate 9. The placing grooves 901 are evenly distributed on the top of the placing plate 9, which helps to place several bolts. The model of the bolts is the commonly used M10.

[0034] Among them, a fixed limiting assembly is provided at the bottom of the placing plate 9, and the fixed limiting assembly includes two installation boxes 10 fixedly installed at the bottom of the placing plate 9, a reset spring 11 fixedly installed inside the installation box 10, and a movable plate 12 fixedly installed on one side of the reset spring 11, which helps the reset spring 11 to drive the movable plate 12 to retract and reset, and a limiting block 13 fixedly installed at the top and bottom of the movable plate 12 and slidably connected to the installation box 10, which helps to limit the movable plate 12 through the limiting block 13, so as to facilitate the stable movement of the movable plate 12.

[0035] In this embodiment, the limiting assembly also includes a movable rod 14 fixedly installed on one side of the movable plate 12 and slidably connected to the installation box 10. The movable rod 14 extends to the outside of the installation box 10, which is convenient for pulling the movable rod 14 to move. A limiting pin 15 is fixedly installed on the side of the movable plate 12 away from the movable rod 14 and plugged into the rotating rod 8. The rotating rod 8 has limiting grooves 801 on both sides. The limiting pin 15 is plugged into the rotating rod 8 through the limiting grooves 801, which helps the limiting pin 15 to limit, fix and disassemble the rotating rod 8.

[0036] The working principle of the above embodiment is:

[0037] When using the bolt processing annealing equipment, firstly, a plurality of bolts to be annealed are placed in the placement groove 901 on the top of the placement plate 9, and then the mounting seat 6 is pulled, and the mounting seat 6 drives the rotating rod 8 to move on the top of the slide rail 4 through the slider 5, and the mounting seat 6 can be moved to the outside of the annealing box body 2, and the movable rod 14 is pulled, and the movable rod 14 drives the movable plate 12 to move horizontally under the limit of the limit block 13, and the movable plate 12 moves while compressing the reset spring 11 until the limit pin 15 moves and contracts, and then the placement plate 9 is passed through the inner side of the rotating rod 8 for movable placement, and at this time, the limit pin 15 just corresponds to the limit groove 801 on the rotating rod 8, and then the movable plate 12 is released. Rod 14, the reset spring 11 starts to reset automatically, and the reset spring 11 drives the movable plate 12 and the limit pin 15 to rebound and move until the limit pin 15 is inserted into the limit groove 801 on the outside of the rotating rod 8, so as to limit and fix the placement plate 9, and then the insulating door 3 can be slid to form a relatively closed space for the annealing box body 2, and the annealing box body 2 can be used for annealing. At this time, the rotating motor 7 can be started, and the rotating motor 7 drives the rotating rod 8 and the placement plate 9 to rotate, thereby driving the bolts on the top of the placement plate 9 to rotate, which helps to increase the uniformity of heating. After annealing, the mounting seat 6 can be slid out again through the slide rail 4, and the placement plate 9 can be taken out, thereby improving the flexibility and practicality of the device.
