Description

Technical Field

[0001] This utility model belongs to the field of high-strength bolt manufacturing technology, specifically relating to a quenching equipment for manufacturing high-strength bolts. Background Technology

[0002] High-strength bolts are bolts manufactured using high-strength alloy steel or through special processes such as heat treatment. They possess high tensile strength, shear strength, and fatigue resistance. They are typically used for connections that withstand large mechanical loads, vibrations, or extreme working conditions, and are widely used in construction, bridges, machinery, railways, aerospace, and other fields. During the production of high-strength bolts, quenching treatment is required to improve their hardness, strength, and wear resistance.

[0003] Chinese patent discloses a quenching mechanism for high-strength bolt production (publication number CN219279964U). This patented technology uses a first motor to drive a lead screw to rotate and move a threaded connecting plate, so that the nozzle sprays quenching liquid in all directions. This solves the problem that existing quenching devices have fixed spray nozzles for quenching liquid when quenching bolts, which cannot quench the bolts in all directions and result in low quenching efficiency.

[0004] However, most existing high-strength bolts are quenched by contacting them with a quenching fluid. During quenching, the quenching fluid cannot be directly recycled, leading to increased energy consumption and hindering the removal of bolts from the plate. As mentioned in the comparative document above, the method of extraction using quenching fluid is employed. In practical applications, the temperature of the bolt increases after quenching, affecting subsequent quenching work. Furthermore, the bolt cannot be quickly removed for replacement after quenching, resulting in low practicality.

[0005] Therefore, those skilled in the art have provided a quenching device for manufacturing high-strength bolts to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a quenching equipment for manufacturing high-strength bolts, which can solve the problems mentioned in the background art.

[0007] The specific technical solution adopted in this utility model is as follows:

[0008] A quenching device for manufacturing high-strength bolts includes a quenching box, connecting plates on both sides of the quenching box, and a top plate mounted on the upper surface of the connecting plates. Cylinders are symmetrically arranged on the upper surface of the top plate. Two sets of lifting plates are arranged inside the quenching box, and a placement plate is slidably installed between the two sets of lifting plates. Electric lifting rods are symmetrically arranged on the upper surface of the lifting plates. A cooling box is arranged outside the quenching box. A stirring motor is installed on the front surface of the cooling box. A rotating shaft is connected to the drive end of the stirring motor. Stirring rods are symmetrically arranged outside the rotating shaft. A pump box is arranged on the upper surface of the cooling box. A first liquid pump and a second liquid pump are arranged from left to right inside the pump box. A cooling fan is arranged in front of the pump box on the upper surface of the cooling box, and an air outlet is opened behind the pump box on the upper surface of the cooling box.

[0009] The present invention is further configured such that: a connecting sleeve is provided at the middle position of the upper surface of the lifting plate, and the telescopic end of the cylinder is embedded inside the connecting sleeve and connected by screws.

[0010] The present invention is further configured such that: a guide groove is provided on one side of the lifting plate, and the two sides of the placement plate are slidably installed inside the guide groove.

[0012] The present invention is further configured such that: the inlet end of the first liquid pump is connected to a third connecting pipe inside the cooling box, and the outlet end of the first liquid pump is connected to a first connecting pipe, and one end of the first connecting pipe extends through the inner side of the quenching box to the interior of the quenching box.

[0013] The present invention is further configured such that: the inlet end of the second liquid pump is connected to a second connecting pipe inside the quenching box, and the outlet end of the second liquid pump is connected to a fourth connecting pipe inside the cooling box.

[0014] The technical effects achieved by this utility model are as follows:

[0015] 1. This design is a quenching equipment for manufacturing high-strength bolts. It uses two cylinders symmetrically arranged on the top plate to operate, which causes the two lifting plates to rise and fall synchronously.

[0022] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1As shown, a quenching device for manufacturing high-strength bolts includes a quenching box 1, connecting plates 21 disposed on both sides of the quenching box 1, and a top plate 2 mounted on the upper surface of the connecting plates 21. Cylinders 3 are symmetrically arranged on the upper surface of the top plate 2. Two sets of lifting plates 31 are disposed inside the quenching box 1, and a placement plate 32 is slidably installed between the two sets of lifting plates 31. Electric lifting rods 33 are symmetrically arranged on the upper surface of the lifting plates 31. A cooling box 4 is disposed outside the quenching box 1. A stirring motor 42 is mounted on the front surface of the cooling box 4. The drive end of the stirring motor 42 is connected to a rotating shaft 421. The external surface of the rotating shaft 421 is symmetrically arranged... A stirring rod 422 is provided, and a pump box 5 is provided on the upper surface of the cooling box 4. The pump box 5 is equipped with a first liquid pump 53 and a second liquid pump 55 from left to right. A cooling fan 41 is provided in front of the pump box 5 on the upper surface of the cooling box 4, and an air outlet 43 is provided behind the pump box 5 on the upper surface of the cooling box 4. This arrangement utilizes the synchronous operation of two cylinders 3 on the top plate 2, which causes the connecting plate 31 to rise and fall inside the quenching box 1, thereby adjusting the position of the placement plate 32 to achieve the purpose of quenching high-strength bolts. It also facilitates the removal of the bolts for quick replacement, making it highly practical.

[0024] like Figure 2 As shown, a connecting sleeve 312 is provided at the middle position of the upper surface of the lifting plate 31. The telescopic end of the cylinder 3 is embedded in the connecting sleeve 312 and connected by screws. This setting uses the connecting sleeve 312 to connect the cylinder 3 and the lifting plate 31. When the cylinder 3 works, the lifting plate 31 will rise and fall, thereby adjusting the height of the placement plate 32. This can achieve the purpose of automatically quenching high-strength bolts.

[0025] like Figure 2 As shown, a guide groove 311 is provided on one side of the lifting plate 31, and the two sides of the placement plate 32 are slidably installed inside the guide groove 311. Limiting holes are symmetrically provided on the upper surface of the placement plate 32, and the telescopic end of the electric lifting rod 33 is embedded in the limiting hole. This setting can ensure the stability of the placement plate 32 by using the telescopic end of the electric lifting rod 33 to be embedded in the limiting hole, and also facilitates its disassembly to replace the high-strength bolts inside.

[0026] like Figure 3 and Figure 4As shown, the inlet end of the first pump 53 is connected to a third connecting pipe 54 inside the cooling box 4, and the outlet end of the first pump 53 is connected to a first connecting pipe 51. One end of the first connecting pipe 51 extends through the inner side of the quenching box 1 into the interior of the quenching box 1. The inlet end of the second pump 55 is connected to a second connecting pipe 52 inside the quenching box 1, and the outlet end of the second pump 55 is connected to a fourth connecting pipe 56 inside the cooling box 4. This arrangement utilizes the operation of the second pump 55 inside the pump box 5 to draw quenching liquid from inside the quenching box 1 through the second connecting pipe 52 and introduce it into the cooling box 4 through the fourth connecting pipe 56. After entering, the cooling is achieved by the cooling fan 41. At the same time, the first pump 53 can draw the cooled quenching liquid inside the cooling box 4 through the third connecting pipe 54 and introduce it into the quenching box 1 through the first connecting pipe 51 to achieve the purpose of recycling.

[0027] The working principle of this utility model is as follows: When using the high-strength bolt manufacturing quenching equipment, the high-strength bolts to be quenched are first placed into the placement slots on the placement plate 32. After placement, they are installed between two lifting plates 31 by sliding. After installation, the electric lifting rod 33 on the lifting plate 31 is activated, causing its telescopic end to embed into the limiting hole on the placement plate 32, thus ensuring the stability of the placement plate 32. After positioning, the two symmetrically arranged cylinders 3 on the top plate 2 are activated, causing the lifting plate 31 to rise and fall, allowing the placement plate 32 to descend into the quenching chamber 1 and come into contact with the quenching liquid. To achieve the purpose of quenching high-strength bolts, when the temperature of the quenching liquid inside the quenching box 1 is high after quenching, the second pump 55 can extract the quenching liquid from the quenching box 1 through the second connecting pipe 52 and introduce it into the cooling box 4 through the fourth connecting pipe 56. After entering, the cooling fan 41 can achieve the purpose of heat dissipation and cooling. The operation of the stirring motor 42 will cause the stirring rod 422 outside the rotating shaft 421 to rotate, thus efficiently dissipating and stirring the quenching liquid. At the same time, the first pump 53 can extract the cooled quenching liquid from the cooling box 4 through the third connecting pipe 54 and introduce it into the quenching box 1 through the first connecting pipe 51 to achieve the purpose of recycling.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
