Description

Technical Field

[0001] The invention belongs to the technical field of welding machine tools and relates to a brazing device, in particular to a welding strip head position correction device of the brazing device. Background Art

[0002] The diamond bit and the base of the diamond cutting tool are usually fixedly connected by brazing. During brazing, a welding strip is placed between the base and the bit, and flux needs to be provided between the welding strip and the base and between the welding strip and the bit.

[0003] In order to improve the brazing efficiency, someone has proposed a welding strip flux supply device for a diamond cutting tool welding machine (application number 201510746639.9), which includes a welding strip guide seat with a guide groove and a flux storage box with a storage cavity, and the storage cavity is connected to the guide groove; a control component is also installed on the welding strip guide seat, and the welding strip guide seat is connected to the frame through a driving assembly.

[0004] In actual use, the welding ribbon flux supply device has the following problems: the welding ribbons are sold in rolls, and it is an objective fact that the bending amplitude of the outer circle of the welding ribbon is smaller than the bending amplitude of the inner circle.

[0005] The welding tape head passing through the welding tape guide seat must have a natural bend. Depending on the installation situation, the welding tape head may bend upward or downward. In short, as the rolled welding tape is continuously used, the bending range of the welding tape head will inevitably increase. Figure 1 and Figure 2 As shown in the figure, if the welding strip head bends downward, the distance between the welding strip head and the top surface of the substrate will gradually decrease, and then in the process of pushing the welding strip head, the welding strip head will be embedded in the water groove, resulting in the welding strip head not being embedded between the substrate and the cutter head; this will inevitably affect the brazing firmness, that is, the welding firmness of the cutter head. Figure 3 As shown, the welding strip head bends upward, resulting in a gradual increase in the distance between the welding strip head and the top surface of the substrate. Since the welding strip is thin and easy to shake, there is a possibility that only part of the welding strip head is embedded between the substrate and the cutter head, or even the welding strip head is not embedded between the substrate and the cutter head. This will inevitably affect the brazing firmness, that is, the welding firmness of the cutter head.

[0006] In order to improve the straightness of the welding strip, someone proposed a welding strip guide seat and welding strip guide device for a diamond cutting tool welding machine (application number 201520299077.3). A welding strip straightening assembly is provided between the welding strip guide seat and the welding strip introduction pressure wheel group. The welding strip straightening assembly includes three straightening rollers positioned on a removable bracket, and the three straightening rollers are distributed in a triangular shape. The technical effect of this welding strip straightening assembly is limited, and it is impossible to make the welding strip in the inner circle area straight; thus, it is unable to solve the above-mentioned technical problems.

[0007] In order to eliminate the above-mentioned technical problems, the inventors thought of using multiple sets of welding ribbon straightening components, and even using stress relief equipment to eliminate the internal stress of the welding ribbon. However, some new technical problems also arise, such as the welding ribbon is not easy to be transported, and even causes the welding ribbon to be broken; the manufacturing cost and the use cost are significantly increased, there are many types of welding ribbons, and the versatility is poor. Summary of the invention

[0008] The present invention provides a device for correcting the position of a welding strip head of a brazing device. The technical problem to be solved by the present invention is how to ensure that the distance between the welding strip head and the top surface of a substrate remains basically consistent.

[0009] The technical problem to be solved by the present invention can be achieved through the following technical solutions: a device for correcting the position of the head of a welding strip of a brazing device, the brazing device includes a welding strip guide seat, the device for correcting the position of the head of the welding strip includes an elastic sheet, one end of the elastic sheet is installed on the welding strip guide seat, when the welding strip is passed through the welding strip guide seat, the head of the welding strip can rely on the other end of the elastic sheet.

[0010] The position of the elastic sheet is installed according to the bending direction of the welding strip head. If the welding strip head bends upward, the elastic sheet is usually installed above the welding strip head, and the elastic sheet can generate a downward thrust on the welding strip head; if the welding strip head bends downward, the elastic sheet is usually installed below the welding strip head, and the elastic sheet can generate an upward thrust on the welding strip head. The elastic sheet not only has elasticity, but also has bending and deformation characteristics. Therefore, the bending amplitude of the elastic sheet can be adjusted according to the bending amplitude of the welding strip head. That is, when the elastic sheet is located above the welding strip head, if the distance between the welding strip head and the top surface of the substrate is too large, the elastic sheet can be bent to deform it, and the other end of the elastic sheet moves downward, and then the elastic sheet forces the welding strip head to move downward; when the elastic sheet is located below the welding strip head, if the distance between the welding strip head and the top surface of the substrate is too small, the elastic sheet can be bent to deform it, and the other end of the elastic sheet moves upward, and then the elastic sheet forces the welding strip head to move upward.

[0011] Compared with the prior art, the present invention proposes a device for correcting the position of a welding strip head, which utilizes the characteristics of an elastic sheet and adjusts the elastic sheet according to the bending deformation amplitude and bending deformation direction of the welding strip head, thereby ensuring that the distance between the welding strip head and the top surface of the substrate remains basically consistent.

[0012] When the elastic sheet is located below the head of the welding ribbon, the cutter head is pressed on the welding ribbon during the brazing process, and the welding ribbon moves downward, forcing the other end of the elastic member to swing downward, thereby increasing the deformation amplitude of the elastic sheet; and when the welding ribbon is melted by heating, the elastic sheet causes the welding ribbon to swing upward, thereby separating the welding ribbon from the heating, thereby reducing the melting and deformation length of the welding ribbon, thereby reducing the consumption of the welding ribbon; experimental statistics show that when welding the same number of cutter heads, the consumption of the welding ribbon is reduced by 5% to 15%.

[0013] The brazing device provided with the welding strip head position correction device does not need to be provided with a welding strip straightening component. The cost of the elastic sheet is extremely low, so the welding strip head position correction device has the advantage of low use cost.

[0016] In the above-mentioned device for correcting the position of the welding strip head of the soldering device, the elastic sheet is in a strip shape.

[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] Embodiment 1: Figures 4 to 6 As shown, the brazing device includes a frame 1, a substrate fixture 6, a tool head fixture 3 and a welding strip guide seat 4. The substrate fixture 6 is used to clamp the top of the substrate in the welding workpiece, the tool head fixture 3 is used to clamp the tool head of the welding workpiece, the substrate fixture 6, the tool head fixture 3 and the welding strip guide seat 4 are all installed on the frame 1, the tool head fixture 3 is located above the substrate fixture 6, and the welding strip guide seat 4 is located on one side of the substrate fixture 6. The attached figure of the specification shows that the welding strip guide seat 4 is located on the right side of the substrate fixture 6.

[0032] A bracket 7 is also installed on the frame 1. The welding ribbon 2 is wound on a reel, and the reel is installed on the bracket 7. When the welding ribbon 2 is pulled, the reel can rotate, and then the welding ribbon 2 is pulled out. The bracket 7 is located on the right side of the welding ribbon guide seat 4. The welding ribbon guide seat 4 has a guide hole, so that the welding ribbon 2 passes through the welding ribbon guide seat 4 through the guide hole, and the welding ribbon 2 is passed from the right side to the left side. The part of the welding ribbon 2 located on the left side of the welding ribbon guide seat 4 is called the welding ribbon head 2a.

[0033] The position correction device of the welding strip head 2a includes an elastic sheet 8, which is in the shape of a strip. The width of the elastic sheet 8 is greater than the width of the welding strip 2, so as to reduce the possibility of the elastic sheet 8 being separated from the welding strip 2. The elastic sheet 8 is a steel sheet or a copper sheet. The elastic sheet 8 has the advantages of large elasticity and the property of bending and deformation. A connecting ring 9 is sleeved on the welding strip guide seat 4, and a locking screw 10 is bolted on the connecting ring 9. One end of the elastic sheet 8 is embedded between the connecting ring 9 and the welding strip guide seat 4, and then the locking screw 10 is screwed to fix the connecting ring 9 on the welding strip guide seat 4, so that one end of the elastic sheet 8 is installed on the welding strip guide seat 4. This structure has the advantages of simple structure and low manufacturing cost; the position correction device of the welding strip head 2a can be removed according to actual conditions, and this structure has the advantage of easy disassembly and assembly; at the same time, the elastic sheet 8 can be installed above or below the welding strip head 2a according to actual conditions, that is, the elastic sheet 8 is inserted between the top surface of the welding strip guide seat 4 and the connecting ring 9, and the elastic sheet 8 is located above the welding strip head 2a; the elastic sheet 8 is inserted between the bottom surface of the welding strip guide seat 4 and the connecting ring 9, and the elastic sheet 8 is located below the welding strip head 2a. By adjusting the length of the elastic sheet 8 inserted between the connecting ring 9 and the welding strip guide seat 4, the length of the elastic sheet 8 that can be freely swung can be adjusted, that is, the length of the elastic sheet 8 that can be freely swung matches the length of the welding strip head 2a.

[0034] By describing the process of adjusting the position of the welding strip head 2a by using the welding strip head 2a position correction device, the functions and advantages of each component are further explained. If the welding strip head 2a is bent downward, the elastic sheet 8 is installed below the welding strip head 2a; Figure 5 As shown, the welding strip head 2a rests on the other end of the elastic sheet 8. The elastic sheet 8 can generate an upward thrust on the welding strip head 2a. As the welding strip 2 is continuously used, the bending deformation amplitude of the welding strip head 2a increases. The elastic sheet 8 can be bent to move the other end of the elastic sheet 8 upward, thereby increasing the upward thrust generated by the elastic sheet 8 on the welding strip head 2a.

[0035] If the welding strip head 2a is bent upward, the elastic sheet 8 is installed above the welding strip head 2a. Figure 6 As shown in the figure, the welding strip head 2a rests on the other end of the elastic sheet 8. The elastic sheet 8 can generate a downward thrust on the welding strip head 2a. As the welding strip 2 is continuously used, the bending deformation amplitude of the welding strip head 2a increases. The elastic sheet 8 can be bent to make the other end of the elastic sheet 8 move downward, thereby increasing the downward thrust generated by the elastic sheet 8 on the welding strip head 2a.

[0036] Embodiment 2: The structure and principle of this embodiment are basically the same as those of Embodiment 1. The basically similarities are not described in detail, and only the differences are described. The differences are as follows: a positioning ring is provided at the other end of the elastic sheet 8, and the welding strip head 2a passes through the positioning ring. This not only helps to limit the swing of the welding strip head 2a and improves the position consistency of the welding strip head 2a, but also enables the elastic sheet 8 to be installed above or below the welding strip head 2a to exert a force on the welding strip head 2a. Therefore, when the welding strip head 2a bends upward and the brazing heating causes the welding strip 2 to melt, the elastic sheet 8 can also make the welding strip 2 swing upward, thereby reducing the loss of the welding strip 2.

[0037] Embodiment 3: The structure and principle of this embodiment are basically the same as those of Embodiment 1. The basic similarities are not described in detail, and only the differences are described. The differences are that one end of the elastic sheet 8 is mounted on the welding strip guide seat 4 by a screw.
