Description

Technical Field

[0001] This utility model belongs to the field of forging processing technology, and specifically relates to a heat treatment device for forgings after forging. Background Technology

[0002] Heat treatment of forgings is a crucial step in metal processing, and its background technology encompasses a wide range of process knowledge and practical experience. Forgings, as fundamental components in mechanical manufacturing, often experience higher stress on their surface layer than in the core when subjected to alternating loads such as torsion and bending, as well as impact loads. Furthermore, they are subject to wear in certain working environments. Therefore, heat treatment, especially surface heat treatment, of forgings to improve their microstructure and properties is of paramount importance.

[0003] Existing forging heat treatment equipment cannot effectively distinguish forging receiving frames of different specifications during forging. When multiple forgings are heat treated simultaneously, placing multiple forgings directly in the forging receiving frame can easily cause collisions and deformation between the forgings. Therefore, a forging post-forging heat treatment equipment is needed to help solve this problem. 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 specific embodiment is a heat treatment device for forgings after forging, such as... Figure 1 and Figure 2 As shown, the forging post-forging heat treatment device includes a receiving box 1, a base frame 2 installed at the bottom of the receiving box 1, a receiving cavity opened inside the receiving box 1, an inverted U-shaped mounting frame 3 fixed at the top of the receiving box 1, a receiving frame 9 installed inside the receiving cavity, the receiving frame 9 has a rectangular box-shaped structure, and a plurality of insertion slots 92 are symmetrically opened on the inner side of the receiving frame 9. The plurality of insertion slots 92 are equidistantly arranged on the inner side of the receiving frame 9, and a baffle plate 10 is inserted and installed between two symmetrical insertion slots 92.

[0029] By using the insertion slot 92 and the baffle plate 10 on the receiving frame 9 to cooperate, the receiving frame 9 can be divided into multiple receiving cavities of corresponding sizes according to the different overall sizes of the forgings during the working process. This enables stable processing of forgings of different sizes and separates the forgings from each other, minimizing the risk of collisions and deformations during heat treatment.

[0030] The aforementioned insertion slot 92 is provided with a positioning hole 93, and the baffle plate 10 is provided with a positioning cavity near the top. A positioning component 11 is installed in the positioning cavity to cooperate with the positioning hole 93 for positioning. The positioning component 11 includes a positioning block 12 slidably disposed in the positioning cavity and a return spring 13 that assists in pushing the positioning block 12.

A connecting belt 14 is fixed between the positioning block 12 and the push rod 15. A transmission wheel 141 is rotatably disposed inside the baffle plate 10. The connecting belt 14 is attached to the transmission wheel 141.

[0031] Through the cooperation between the positioning component 11 and the positioning hole 93 inside the baffle plate 10, the push rod 15 pulls the connecting belt 14. During the pulling of the connecting belt 14, the positioning block 12 moves as a whole, thereby compressing the return spring 13. At this time, the baffle plate 10 is inserted into the insertion slot 92. Then, the push rod 15 is released, and the positioning block 12 is inserted into the positioning hole 93, thus completing the overall positioning of the baffle plate 10. This minimizes the risk of the baffle plate 10 slipping out during heat treatment, ensuring that the baffle plate 10 is in the correct position.

A lifting motor 8 that drives the lifting rod 5 to rotate is installed on the outer side of the receiving box 1.

[0033] The lifting assembly 4 is set up so that the lifting motor 8 drives the lifting rod 5 to rotate as a whole. The lifting rod 5 drives the grooved wheel 6 to rotate as a whole, and drives the transmission belt 7 to rotate as a whole. During the rotation of the transmission belt 7, the two grooved wheels 6 rotate as a whole, and both lifting rods 5 rotate. The lifting rod 5 is threadedly engaged with the protruding block 91, so that the protruding block 91 can move as a whole, thereby facilitating the movement of the receiving frame 9 to the specified height.

[0034] Reference Figure 1 and Figure 4As shown, the bottom of the receiving cavity of the receiving box 1 is funnel-shaped, and an outlet is provided at the bottom of one end of the receiving box 1. A discharge cylinder 16 is installed at the outlet. A spiral conveying shaft 18 is rotatably arranged inside the receiving box 1 corresponding to the outlet. A servo motor that drives the conveying shaft 18 to rotate is installed at the end of the receiving box 1 away from the discharge cylinder 16.

[0035] The discharge cylinder 16 and the conveying shaft 18 inside it can effectively clean and discharge the impurities generated inside the container 1 after heat treatment after operation.

[0036] One end of the discharge cylinder 16 is hinged to a sealing cover 17. A sealing groove 161 is provided on the side of the discharge cylinder 16 facing the sealing cover 17. A sealing strip 171 is provided on the side of the sealing cover 17 facing the discharge cylinder 16. The sealing groove 161 and the sealing strip 171 are fitted together to seal.

The positioning bolt 20 is threadedly engaged with the threaded hole on the protrusion 19.

[0037] The cooperation between the positioning bolts 20 and the protrusions 19 ensures that the sealing cover 17 can be stably installed on the discharge cylinder 16 during operation. The cooperation between the sealing strip 171 and the sealing groove 161 ensures that the connection between the discharge cylinder 16 and the sealing cover 17 can be stably sealed during operation.

[0038] Working principle:

[0039] Before cooling forgings of different lengths, the baffle plate 10 is inserted into the corresponding insertion slot 92 according to the overall size of the forging. Pressing the push rod 15 causes the connecting belt 14 to be pulled. During the pulling of the connecting belt 14, the positioning block 12 moves as a whole, thereby compressing the return spring 13. At this time, the baffle plate 10 is inserted into the insertion slot 92. Then, the push rod 15 is released, and the positioning block 12 is inserted into the positioning hole 93, thus completing the overall positioning of the baffle plate 10.

[0040] During operation, the lifting motor 8 is started, which drives the lifting rod 5 to rotate as a whole. The lifting rod 5 drives the grooved wheel 6 to rotate as a whole, and drives the transmission belt 7 to rotate as a whole. During the rotation of the transmission belt 7, the two grooved wheels 6 rotate as a whole, and both lifting rods 5 rotate. The lifting rod 5 is threadedly engaged with the protruding block 91, thereby causing the protruding block 91 to move as a whole, which in turn causes the receiving frame 9 to move as a whole to the receiving cavity, and then the forging is subjected to auxiliary heat treatment.

[0041] After heat treatment, when it is necessary to clean the impurities at the bottom of the container 1, reverse the positioning bolt 20. The positioning bolt 20 is threadedly engaged with the threaded hole, thereby loosening the positioning bolt 20 from the threaded hole on the protrusion 19. At this time, open the sealing cover 17 to achieve the overall discharge of the liquid. After the liquid is discharged, start the servo motor. The servo motor drives the conveyor shaft 18 to rotate as a whole. The conveyor shaft 18 assists in cleaning the impurities accumulated at the bottom of the container 1.
