Description

Technical Field

[0001] This utility model relates to the field of tempering equipment technology, specifically to round steel tempering equipment. Background Technology

[0002] During the processing of round steel bars, they are heated by a heating device and then rapidly cooled in a cooling box. They are then tempered by a heating device to give the round steel bars good overall mechanical properties. However, rapid cooling can cause significant thermal stress within the round steel bars, leading to cracks at both ends. These ends need to be repaired, which affects the overall production efficiency of the round steel bars. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a round steel pressing device, which solves the problem of cracking at both ends when the round steel is rapidly cooled after heating.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A round steel bar pressing device, including a frame, the frame being equipped with a heating device and a cooling device, and further comprising:

[0006] An annular sleeve is disposed between the heating device and the cooling device, and the annular sleeve has an annular cavity inside;

[0007] Spray holes are evenly distributed on the inner wall of the annular sleeve and communicate with the annular cavity;

[0008] The water inlet pipe is installed on the annular sleeve and communicates with the annular cavity.

[0009] Mounting bracket, mounted on the frame, is used to fix the water inlet pipe;

[0010] A power element is used to connect to the mounting base and drive the mounting base to move horizontally.

[0011] The mounting base has guide blocks on both sides of its bottom, and the frame has guide rods for cooperating with the guide blocks.

[0012] A protective cover is provided between the heating device and the cooling device, and the annular sleeve is located inside the protective cover.

[0013] The power component is a cylinder.

[0014] The water inlet pipe includes a stainless steel pipe connected to the annular sleeve and a flexible hose connected to the stainless steel pipe.

[0015] The vertical and horizontal distances between the annular sleeve and the mounting base are adjustable.

[0016] The mounting base is provided with a vertically arranged lead screw mechanism, and the water inlet pipe is mounted on the lead screw mechanism. The lead screw mechanism includes a mounting base and a lead screw. The front end of the mounting base is provided with a locking block for cooperating with the lead screw, and the locking block is equipped with a locking element.

[0017] The beneficial effects of this utility model are:

[0018] Before the heated round steel enters the cooling device, water is sprayed circumferentially from the inner wall of the annular sleeve to cool the ends of the round steel. At the same time, the power element drives the annular sleeve to move synchronously with the round steel, gradually cooling the ends of the round steel, reducing stress concentration, and effectively preventing cracking at both ends of the round steel.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] In the embodiments, such as Figure 1 , Figure 2 As shown, the round steel pressing equipment includes a frame, the frame being equipped with a heating device 1 and a cooling device 2, and further includes:

[0025] An annular sleeve 3 is disposed between the heating device 1 and the cooling device 2, and an annular cavity 4 is provided inside the annular sleeve 3.

[0026] Spray holes 5 are evenly distributed on the inner wall of the annular sleeve 3 and communicate with the annular cavity 4;

[0027] The water inlet pipe 6 is installed on the annular sleeve 3 and communicates with the annular cavity 4;

[0028] Mounting base 7, set on the frame, is used to fix the water inlet pipe 6;

[0029] The power element 8 is used to connect with the mounting base 7 and drive the mounting base 7 to move horizontally.

[0030] Before the heated round steel enters the cooling device 2, water is sprayed circumferentially from the inner wall of the annular sleeve 3 to cool the ends of the round steel. At the same time, the power element 8 drives the annular sleeve 3 to move synchronously with the round steel, gradually cooling the ends of the round steel, reducing stress concentration, and effectively preventing cracking at both ends of the round steel.

[0031] In the embodiments, such as Figure 1 As shown, guide blocks 9 are provided on both sides of the bottom of the mounting base 7, and guide rods 10 are provided on the frame to cooperate with the guide blocks 9. This ensures the straightness of the movement of the mounting base 7 and ensures the quality of cooling.

[0032] In the embodiments, such as Figure 1 As shown, a protective cover 11 is provided between the heating device 1 and the cooling device 2, and the annular sleeve 3 is located inside the protective cover 11. This serves to protect workers from burns.

[0033] In this embodiment, the power element 8 is a cylinder. The cylinder can smoothly drive the mounting base 7 to move with high precision.

[0034] In the embodiments, such as Figure 2 As shown, the water inlet pipe 6 includes a stainless steel pipe 61 connected to the annular sleeve 3 and a flexible hose 62 connected to the stainless steel pipe 61. The stainless steel pipe 61 is easy to fix on the mounting base 7 and is not easily damaged by the high temperature of the round steel. The flexible hose 62 is easy to bend and convenient to connect to the water tank.

[0035] In the embodiments, such as Figure 1 As shown, the vertical and horizontal distances between the annular sleeve 3 and the mounting base 7 are adjustable. By adjusting the distance of the annular sleeve 3, the annular sleeve 3 is made to fit concentrically with the round steel, ensuring uniform circumferential cooling of the round steel.

[0036] In the embodiments, such as Figure 3 As shown, the mounting base 7 is equipped with a vertically arranged screw mechanism, and the water inlet pipe 6 is mounted on the screw mechanism. The screw mechanism includes a fixed base 12 and a screw 13. The front end of the fixed base 12 is provided with a locking block 14 for cooperating with the screw 13, and the locking block 14 is equipped with a locking element 15. The annular sleeve 3 can be adjusted up and down and back and forth by means of the screw 13 on the horizontal and vertical screw mechanisms, which is convenient for adjustment. The locking element 15 is a hand-tightening bolt. After adjustment, the locking block 14 is used to lock the screw 13 to ensure the stability of the annular sleeve 3.

[0037] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
