Description

Technical Field

[0001] This utility model relates to the field of brazing technology, specifically a continuous brazing device for cemented carbide cutting tips and tooth bodies. Background Technology

[0002] Brazing of carbide cutting tips and tooth bodies is a common process widely used in mining, engineering machinery and other fields. Brazing technology melts the filler metal by heating, thereby firmly connecting the carbide cutting tip to the pre-set notch of the tooth body to improve the wear resistance and service life of the tooth body. Traditional brazing methods usually use flame heating or high-frequency induction heating, combined with manual operation to complete the positioning and welding of the cutting tip.

[0003] Since the cutter head needs to be manually adjusted one by one to match the notch on the tooth body, the operation is not only cumbersome, but also prone to causing workers to be burned due to the high temperature environment. In addition, manual calibration is difficult to guarantee the precise alignment of the cutter head and the notch, which may affect the welding quality and reduce the overall performance of the tooth body. Therefore, a continuous brazing equipment for cemented carbide cutter heads and tooth bodies is needed to solve the existing shortcomings. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing manual adjustment methods for alloy cutter heads, which have poor precision at the notch of the tooth body and are prone to burns.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous brazing device for cemented carbide cutting tips and tooth bodies, comprising a mounting block, heaters fixedly connected to both sides of the mounting block, a tooth body disposed on the opposite side of the heaters, the tooth body having several notches for brazing the cutting tip body, a support block rotatably connected to the top of the mounting block, and a support block fixedly connected to the top of the support block, a pushing component fixedly connected to the top of the support block for controlling the movement of the cutting tip body at the top of the support block, and a limiting component fixedly connected to the support block for controlling the direction of movement of the cutting tip body toward the notches.

[0006] Furthermore, the propulsion assembly includes a push block and a cylinder. The cylinder is fixedly connected to the top of the support block, and the push block is fixedly connected to the telescopic end of the cylinder. The push block is L-shaped, and the cutter head body is attached to the inner side of the push block.

[0007] Furthermore, the support block is provided with a guide groove, and the bottom end of the push block slides in conjunction with the inner side of the guide groove. The width of the cutter head body is greater than the width of the support block.

[0008] Furthermore, the limiting assembly includes a movable frame, a connecting rod, a slider, and a limiting rod. The movable frame is symmetrically arranged, and the bottom end of each movable frame is movably connected to a connecting rod via a pivot. The other end of the connecting rod is rotatably connected to the side of the slider via a pivot. The limiting rod is symmetrically arranged, and the bottom end of each limiting rod is connected to the top end of the movable frame. The tooth body is located on the opposite side of the limiting rod.

[0009] Furthermore, the movable frame is L-shaped, the movable frame passes through the support block, and the movable frame is movably connected to the support block, with the cutter head body located on the opposite side of the movable frame.

[0010] Furthermore, a second cylinder is fixedly connected to the bottom of the support block, and the telescopic end of the second cylinder is fixedly connected to the slider, with the top end of the slider slidingly engaged with the bottom end of the support block.

[0011] Furthermore, the limiting assembly also includes a first rotating rod and a second rotating rod. The first rotating rod is rotatably connected to the top of one of the movable frames and is fixedly inserted through the bottom end of the limiting rod. The second rotating rod is rotatably connected to the top of the other movable frame and is fixedly inserted through the bottom end of the limiting rod. One end of the first rotating rod is movably sleeved on one end of the second rotating rod.

[0012] Compared with existing technologies, this continuous brazing equipment for cemented carbide cutting tips and tooth bodies has the following advantages:

[0013] I. This utility model, through the set propulsion component, places the cutter head body on the support block. Through cylinder one, the support block can be controlled to slide along the guide groove, so that the cutter head body moves forward stably to the notch of the tooth body. It is also beneficial to control the stability of the cutter head body, so that it always maintains a state of contact with the tooth body during the heating process. Compared with manual operation, it is more convenient, and the high temperature at the brazing point will not cause injury to the human body.

[0014] Second, this utility model, through the setting of the limiting component and the cylinder two, can control the slider to slide along the bottom of the support block, thereby driving the connecting rod to rotate, so that the moving frames move closer to each other until the limiting rod is in contact with the side of the tooth body. At the same time, the bottom side of the moving frame is in contact with the side of the cutter head body, which is conducive to the position correction of the cutter head body, so that the support block always moves forward in the direction aligned with the notch, thus eliminating the need for manual calibration and improving the matching efficiency and accuracy of the cutter head body and the notch.

[0020] 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.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a continuous brazing device for cemented carbide cutting tips and tooth bodies, including a mounting block 1. Heaters 2 are fixedly connected to both sides of the mounting block 1, and a tooth body 3 is provided on the opposite side of the heaters 2. The heaters 2 are high-frequency induction coils, which heat the cutting tip body 4 so that the cutting tip body 4 can be brazed onto the notch of the tooth body 3. The tooth body 3 has several notches for brazing the cutting tip body 4. A support block 5 is rotatably connected to the top of the mounting block 1. A drive mechanism can be set on the mounting block 1 to adjust the angle of the support block 5 so that the moving angle of the cutting tip body 4 matches the angle of the notch, thus eliminating the need for secondary position adjustment of the cutting tip body 4. A support block 6 is fixedly connected to the top of the support block 5, and a pusher component 7 is fixedly connected to the top of the support block 6 to control the movement of the cutting tip body 4 at the top of the support block 6. A limit component 8 is fixedly connected to the support block 6 to control the moving direction of the cutting tip body 4 toward the notch.

[0022] This brazing equipment uses a heater 2 to rapidly heat the connection between the cutter head body 4 and the tooth body 3 by contacting the cutter head body 4 with the notch of the tooth body 3, and then rapidly connects them under the action of flux. In addition, the tooth body 3 is driven to rotate by a control mechanism so that it can be continuously brazed.

[0023] like Figure 1 and Figure 3As shown, the propulsion assembly 7 includes a push block 701 and a cylinder 702. The cylinder 702 is fixedly connected to the top of the support block 6, and the push block 701 is fixedly connected to the telescopic end of the cylinder 702. The push block 701 is L-shaped, and the cutter head body 4 is attached to the inner side of the push block 701. The support block 6 is provided with a guide groove 9, and the bottom end of the push block 701 slides in cooperation with the inner side of the guide groove 9. The width of the cutter head body 4 is greater than the width of the support block 6.

[0024] By placing the cutter head body 4 on the support block 6, the cylinder 702 can control the support block 6 to slide along the guide groove 9, so that the cutter head body 4 can move forward stably to the notch of the tooth body 3. This also helps to control the stability of the cutter head body 4, so that it always maintains contact with the tooth body 3 during the heating process. Compared with manual operation, it is more convenient, and the high temperature at the brazing point will not cause injury to the human body.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the limiting assembly 8 includes a movable frame 801, a connecting rod 802, a slider 803, and limiting rods 804. The movable frames 801 are symmetrically arranged, and the bottom ends of each movable frame 801 are movably connected to the connecting rod 802 via a pivot. The other end of the connecting rod 802 is rotatably connected to the side of the slider 803 via a pivot. The limiting rods 804 are symmetrically arranged, and the bottom ends of the limiting rods 804 are respectively connected to the top ends of the movable frames 801. The tooth body 3 is located on the opposite side of the limiting rods 804. The movable frame 801 is L-shaped, passes through the support block 6, and is movably connected to the support block 6. The cutter head body 4 is located on the movable frame 801. On the opposite side of the frame 801, the bottom of the support block 6 is fixedly connected to a cylinder 10, and the telescopic end of the cylinder 10 is fixedly connected to the slider 803. The top of the slider 803 is slidably engaged with the bottom of the support block 6. The limiting component 8 also includes a first rotating rod 805 and a second rotating rod 806. The first rotating rod 805 is rotatably connected to the top of one of the movable frames 801, and the first rotating rod 805 is fixedly inserted through the bottom of the limiting rod 804. The second rotating rod 806 is rotatably connected to the top of the other movable frame 801, and the second rotating rod 806 is fixedly inserted through the bottom of the limiting rod 804. One end of the first rotating rod 805 is movably sleeved on one end of the second rotating rod 806.

[0026] The cylinder 10 controls the slider 803 to slide along the bottom of the support block 6, thereby driving the connecting rod 802 to rotate, causing the moving frame 801 to move closer to each other until the limiting rod 804 is in contact with the side of the tooth body 3. At the same time, the bottom side of the moving frame 801 is in contact with the side of the cutter head body 4, which is beneficial for the position correction of the cutter head body 4, so that the support block 6 always moves forward in the direction aligned with the notch, thus eliminating the need for manual calibration and improving the matching efficiency and accuracy of the cutter head body 4 and the notch.

[0027] In addition, by rotating the first rotating rod 805, the angle of one of the limiting rods 804 can be adjusted, and since the end of the first rotating rod 805 is in movable engagement with the end of the second rotating rod 806, the limiting rod 804 can be adjusted to the side of the tooth body 3 after the tooth body 3 is installed.

[0028] Working principle: In use, firstly, the cutter head body 4 is placed on the support block 6 using a tool. Then, the second cylinder 10 controls the slider 803 to slide along the bottom of the support block 6, thereby driving the connecting rod 802 to rotate, causing the moving frames 801 to move closer together until the limiting rod 804 is in contact with the side of the tooth body 3. At the same time, the bottom side of the moving frame 801 is in contact with the side of the cutter head body 4, which is beneficial for the position correction of the cutter head body 4, so that the support block 6 always moves forward in the direction aligned with the notch. Then, the first cylinder 702 controls the support block 6 to slide along the guide groove 9, so that the cutter head body 4 moves forward stably to the notch of the tooth body 3. Finally, the heater 2 is used to braze the cutter head body 4 to the notch of the tooth body 3. Then, the tooth body 3 is controlled to continue rotating to the next notch, and the above operation is repeated.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
