Since fasteners are subjected to tensile and shear forces during use, they are required to have comprehensive mechanical properties such as sufficient tensile strength, yield strength, fatigue strength, and appropriate hardness. The factors that affect the above properties of fastener bolts are material selection and heat treatment process. Using heat treatment equipment to heat treat fasteners can effectively improve the comprehensive mechanical properties of the finished fasteners, so that the fasteners meet the use requirements.

[0025] The embodiment of the present application discloses a fastener heat treatment device, which is used to ensure that the heat treatment of multiple fasteners is as uniform as possible.

[0026] Reference Figure 1 and Figure 2 A fastener heat treatment equipment includes a heat treatment box 1 with an opening at the right end. A material rack 2 is provided in the heat treatment box 1. The material rack 2 can arrange a plurality of fasteners in an orderly manner. The heat treatment box 1 can perform heat treatment on the parts inside. The specific structure of the heat treatment box 1 is prior art and will not be described here. The heat treatment box 1 is provided with a driving mechanism 3 connected to the material rack 2. The driving mechanism 3 can drive the material rack 2 to rotate and drive the material rack 2 to extend out of the heat treatment box 1 / return to the heat treatment box 1. In order to ensure the heat treatment effect on the fasteners, the heat treatment box 1 is also provided with a closing mechanism 4, which can open / close the opening.

[0027] First, the closing mechanism 4 is driven to open the opening, and then the driving mechanism 3 is driven to drive the material rack 2 to extend out of the heat treatment box 1. After that, the workers arrange multiple fasteners on the material rack 2 in an orderly manner. Then, the driving mechanism 3 is driven to drive the material rack 2 back to the heat treatment box 1 and ensure that the closing mechanism 4 closes the opening. The fasteners are heat treated in the heat treatment box 1 and the driving mechanism 3 is driven to drive the material rack 2 to rotate. After the heat treatment is completed, the closing mechanism 4 opens the opening, and the driving mechanism 3 is driven to drive the material rack 2 to extend out of the heat treatment box 1 and is collected by the workers.

[0028] The orderly arranged fasteners can initially ensure uniform heat treatment, and the driving mechanism 3 drives the material rack 2 to rotate to drive the fasteners to rotate, which can further ensure uniform heat treatment.

[0029] Reference Figure 1 and Figure 2 The driving mechanism 3 includes a frame 31 arranged at the left end of the heat treatment box 1, and a driving member 32 is arranged on the frame 31. The driving member 32 is a telescopic rotating cylinder. The driving member 32 is connected to a linkage rod 33, and the linkage rod 33 is made of heat insulation material; the heat treatment box 1 is provided with a connecting hole 11, the linkage rod 33 is passed through the connecting hole 11 and is connected to the material rack 2, and the driving member 32 can drive the linkage rod 33 to rotate and extend, thereby driving the material rack 2 to rotate and move.

[0030] Reference Figure 2 and Figure 3 The rack 2 includes a mounting plate 21 connected to the linkage rod 33. The mounting plate 21 is located at the right end of the mounting plate 21. A plurality of supporting rod groups 22 are provided. Figure 4 The plurality of support rod groups 22 are evenly distributed along the circumferential direction of the mounting plate 21, and each support rod group 22 can place a plurality of fasteners in an orderly manner in the transverse direction. Specifically, the support rod group 22 includes a connecting circular plate 221 disposed on the mounting plate 21, and a plurality of limiting rods are disposed at one end of the connecting circular plate 221 away from the mounting plate 21, and the area surrounded by the plurality of limiting rods is a storage area 23 for placing a plurality of fasteners.

[0031] In this embodiment, there are three limit rods, and the three limit rods are evenly distributed along the circumferential direction of the connecting circular plate 221, that is, distributed in an equilateral triangle shape; in other embodiments, the limit rods can also be four, five or more, as long as a storage area 23 for placing fasteners can be formed between the multiple limit rods.

[0032] Reference Figure 5 In this embodiment, the limiting rods distributed in a triangular shape can facilitate the placement of fasteners of different shapes, such as pins, bolts, cylindrical nuts, etc. In order to improve the feeding efficiency, the fasteners can also be automatically fed by a robot in this application.

[0033] Reference Figure 4 In the heat treatment process, if part of the surface of the fastener to be treated is covered, the heat treatment effect of the fastener may be uneven or poor. In the present application, the surface of the fastener can be fully exposed: taking the three limit rods around one of the storage areas 23 as an example, the three limit rods are limit rod 1 222, limit rod 223 and limit rod 3 224. When the driving member 32 drives the three limit rods to rotate to different positions, the fastener located in the storage area 23 will contact different limit rods. For example, when the fastener reaches the highest position, the fastener will contact the limit rod 1 222 and the limit rod 223. When the fastener reaches the lowest position, the fastener will contact the limit rod 3 224. Figure 2That is, when the driving member 32 drives the mounting plate 21 to rotate one circle, all surfaces of the fastener can be exposed.

[0034] Reference Figure 2 The closing mechanism 4 includes a fixing frame 41 arranged on the heat treatment box 1, and a power member 42 is arranged on the fixing frame 41. The power member 42 is preferably a cylinder, and the power member 42 is connected to a closing door 43.

The mounting rod 52 is hingedly connected to the heat treatment box 1, and the frame 5 and the heat treatment box 1 are also hingedly connected. The reciprocating feed member 51 can drive the heat treatment box 1 to bend down or look up through the mounting rod 52, thereby driving the material rack 2 to bend down or look up.

[0036] After the fasteners are placed on the rack 2, the reciprocating feed member 51 is driven to cause the heat treatment box 1 to slightly tilt up to ensure that the fasteners do not fall off. After the heat treatment is completed, the driving mechanism 3 is driven to cause the rack 2 to extend out of the heat treatment box 1, and then the reciprocating feed member 51 is driven to drive the heat treatment box 1 to bend down to pour out the fasteners on the rack 2. Of course, if the fasteners are not completely poured out, they are assisted by workers to unload them. The present application can facilitate the loading and unloading of fasteners.

[0037] The implementation principle of a fastener heat treatment device in the embodiment of the present application is: First, the power member 42 is driven to drive the closed door 43 to move and open the opening, and then the driving member 32 is driven to drive the material rack 2 to move right and extend outside the heat treatment box 1. After that, the worker arranges multiple fasteners in multiple material storage areas 23 in an orderly manner, and then drives the driving member 32 to drive the material rack 2 back to the heat treatment box 1 and ensures that the power member 42 drives the closed door 43 to move to close the opening, drives the reciprocating feed member 51 to drive the heat treatment box 1 to slightly tilt up, and uses the heat treatment box 1 to heat treat the fasteners while driving the driving member 32 to drive the material rack 2 to rotate. After the heat treatment is completed, the power member 42 starts to open the opening, drives the driving member 32 to drive the material rack 2 to extend outside the heat treatment box 1, drives the reciprocating feed member 51 to drive the heat treatment box 1 to bend down to pour out the fasteners on the material rack 2, and finally the worker collects the fasteners. The present application can ensure uniform heat treatment of multiple fasteners as much as possible.
