Description

Technical Field

[0001] This invention relates to the field of welding, and more particularly to a high-efficiency welding machine for the production of metal tools. Background Technology

[0002] The welding process for machine tool and milling machine cutters typically employs high-frequency electromagnetic induction brazing. High-frequency electromagnetic induction brazing is a welding method that uses a high-frequency current to generate an alternating magnetic field in a coil, causing eddy currents inside the workpiece or filler metal, resulting in rapid self-heating, melting the filler metal, wetting the base material, and forming a strong joint. Currently, welding cutters requires manual handling of the tool holder, inserting the tool holder and cutting edge into the coil for welding. During the welding process, the filler metal and flux melt, requiring manual adjustment of the tool holder and cutting edge, resulting in poor welding precision. Although the coil itself does not generate heat, the tool holder and cutting edge heat up rapidly under electromagnetic induction, and this heat radiates to the coil, making the coil hot. Furthermore, due to the precision requirements of cutter welding, wearing gloves is inconvenient for operation, and manually holding the tool holder and cutting edge increases the risk of accidentally touching the coil and getting burned. Summary of the Invention

[0003] To overcome the shortcomings of existing high-frequency electromagnetic induction brazing, which requires manual holding of the tool holder and adjustment of the tool holder and blade, resulting in poor welding accuracy, this invention provides a high-efficiency welding machine for metal tool production.

[0005] Furthermore, it is particularly preferred that the adjusting assembly includes: a horizontal screw, a horizontal slider, a vertical screw, a limiting rod, and a vertical slider; a horizontal screw for controlling the mounting rod and adjusting the L-shaped block horizontally is rotatably connected to the left mounting plate; the horizontal screw is threadedly connected to the horizontal slider; the horizontal slider is slidably connected to the left mounting plate; a vertical screw for controlling the mounting rod and adjusting the L-shaped block vertically is rotatably connected to the horizontal slider; a vertical slider is threadedly connected to the vertical screw; a limiting rod for restricting the rotation of the vertical slider is installed on the horizontal slider; the limiting rod is slidably connected to the vertical slider.

[0006] Furthermore, it is particularly preferred that a shielding cover is also included; a shielding cover for shielding the induction coil is fixedly attached to the left mounting plate.

[0007] In addition, preferably, it also includes a plug-in block and a locking block; the plug-in block is fixedly connected to the left mounting plate; one end of the support plate is plugged into the plug-in block; several locking slots are opened at the other end of the support plate; several locking blocks are fixedly connected to the top of the right mounting plate; the locking blocks are compatible with the locking slots.

[0008] Furthermore, preferably, it also includes mounting blocks, rubber bands, and pressing plates; two mounting blocks are mounted on the upper side of the right mounting plate; a rubber band is fixedly connected to each mounting block; a pressing plate for clamping the tool workpiece is fixedly connected between the two rubber bands; two limiting grooves are provided on the upper side of the right mounting plate; several adjusting grooves are provided on each mounting block; the adjusting grooves are adapted to the limiting grooves; each mounting block engages with a limiting groove through the adjusting groove.

[0009] Furthermore, it is particularly preferred that the device also includes an elastic element; the mounting rod is slidably connected to the vertical slider; and an elastic element for the mounting rod to self-reset is connected between the mounting rod and the vertical slider.

Moreover, when welding tools of the same specifications, it is only necessary to place the tool and workpiece in place. There is no need to readjust the installation rod and L-block. Only an initial adjustment is required, and it can be used multiple times, improving the continuity and efficiency of welding. Although the induction coil itself does not generate heat, the cutting tool heats up rapidly under electromagnetic induction, and its temperature radiates heat to the induction coil, giving the induction coil heat. When the cutting tool is loaded and unloaded, the shield covers the induction coil to prevent workers from accidentally touching the induction coil and getting burned. When welding, the shield moves with the left mounting plate and moves away from the induction coil, allowing workers to check the welding condition inside the induction coil. The rubber band drives the extrusion plate to press the tool holder against the L-shaped block, and then the tool holder presses the blade onto the L-shaped block. During subsequent welding, the blade restricts the molten brazing filler metal and flux, so that the blade is not displaced by the brazing filler metal and flux.

If there are many hard lumps adhering to the support plate and affecting the placement of the tool, the support plate can be quickly removed, and the hard lumps can be shaken off and removed by tapping the support plate. Then the support plate can be reinstalled for use. Attached Figure Description

[0019] The adjustment assembly includes: a horizontal screw 31, a horizontal slider 32, a vertical screw 33, a limiting rod 34, and a vertical slider 35; the horizontal screw 31 is rotatably connected to the left mounting plate 21; the horizontal screw 31 is threadedly connected to the horizontal slider 32; the horizontal slider 32 is slidably connected to the left mounting plate 21; the vertical screw 33 is rotatably connected to the horizontal slider 32; the vertical screw 33 is threadedly connected to the vertical slider 35; the limiting rod 34 is installed on the horizontal slider 32; the limiting rod 34 is slidably connected to the vertical slider 35.

[0020] It also includes a shield 7; the shield 7 is fixed to the side of the left mounting plate 21 facing the right mounting plate 22; when feeding materials, the shield 7 covers the induction coil 6 to prevent workers from touching the induction coil 6 which is hot and getting burned.

[0021] It also includes a plug-in block 201 and a locking block 202; the plug-in block 201 is fixedly connected to the side of the left mounting plate 21 facing the right mounting plate 22; one end of the support plate 3 is plugged into the plug-in block 201; two locking slots 301 are opened at the other end of the support plate 3; two locking blocks 202 are fixedly connected to the top of the right mounting plate 22; the locking blocks 202 are adapted to the locking slots 301.

[0022] It also includes mounting blocks 8, rubber bands 9, and extrusion plates 10; two mounting blocks 8 are mounted on the upper side of the right mounting plate 22; a rubber band 9 is fixedly connected to each mounting block 8; an extrusion plate 10 is fixedly connected between the two rubber bands 9; two limiting grooves 203 are opened on the upper side of the right mounting plate 22; five adjusting grooves 801 are opened on the lower side of each mounting block 8; the adjusting grooves 801 are adapted to the limiting grooves 203; each mounting block 8 is engaged with a limiting groove 203 through the adjusting groove 801.

[0023] It also includes an elastic element 401; the mounting rod 4 is slidably connected to the vertical slider 35; the elastic element 401 is connected between the mounting rod 4 and the vertical slider 35; the elastic element 401 is a spring and is sleeved with the mounting rod 4.

[0024] The interface between the plug block 201 and the support plate 3 is flared to facilitate the insertion and connection of the support plate 3.

[0025] The upper side of the right mounting plate 22 is recessed to improve the fixing effect on the support plate 3; the locking block 202 is located in the recess.

[0026] A handle is fixed to the right mounting plate 22, which makes it easy for workers to move the right mounting plate 22, thereby moving the left mounting plate 21, the support plate 3, and the cutting tool / workpiece.

[0027] It should be noted that the left mounting plate 21, right mounting plate 22, connecting strip 23 and support plate 3 of the present invention are all made of aluminum oxide material, and do not generate heat due to electromagnetic induction with the induction coil 6.

[0028] When using this invention: When placing the tool or workpiece, the worker holds the handle of the right mounting plate 22 and moves it to the right. This moves the left mounting plate 21, the support plate 3, the mounting rod 4, and the L-shaped block 5 to the right until the L-shaped block 5 protrudes to the left from the induction coil 6 and is no longer obstructed by it. The worker then places the tool holder on the support plate 3 and adjusts the position of the L-shaped block 5 according to the tool holder size. Specifically, this is done by rotating the horizontal screw 31, causing the horizontal slider 32 and its connected vertical screw 33 and limit rod 3 to move. 4. Move the vertical slider 35, mounting rod 4, and L-shaped block 5 forward or backward to adjust the front-to-back position of the L-shaped block 5; rotate the vertical screw 33 to move the vertical slider 35, mounting rod 4, and L-shaped block 5 up or down to adjust the vertical position of the L-shaped block 5. When adjusting up and down, ensure that the upper side of the L-shaped block 5 is higher than the tool holder; then, align the groove on the tool holder where the blade is placed with the right angle of the L-shaped block 5, and push the tool holder against the support plate 3 towards the L-shaped block 5, so that the tool holder contacts the L-shaped block 5 without... The L-shaped block 5 is moved to seal the edge of the groove on the tool holder. Then, the worker fills the groove with brazing filler metal and flux. Next, the worker places the blade into the groove, on top of the brazing filler metal and flux. If the blade is larger than the groove, the L-shaped block 5 will block the blade from being placed in. The worker needs to move the tool holder a short distance away from the L-shaped block 5 so that the blade can be accommodated between the L-shaped block 5 and the groove. After the blade is in place, the tool holder is moved towards the L-shaped block 5. The inner wall of the groove in the tool holder then presses the blade against the L-shaped block 5. The L-shaped block 5, in conjunction with the groove in the tool holder, limits the blade. Then, the right mounting plate 22 is moved to the left again, causing the left mounting plate 21, the support plate 3, the mounting rod 4, and the L-shaped block 5 to move to the left, driving the tool holder to the left until the blade on the tool holder is inside the induction coil 6. At this time, the welding machine 61 is started. The induction coil 6 generates electromagnetic induction with the tool holder, blade, brazing filler metal, and flux, causing the tool holder and blade to heat up rapidly. The brazing filler metal and flux melt and weld the blade onto the tool holder, completing the welding.

[0029] Next, the left mounting plate 21, right mounting plate 22, and support plate 3 are moved to the right, causing the welded tool to retract from the induction coil 6. The shield 7 moves with the left mounting plate 21, covering the induction coil 6 to prevent workers from touching the heated coil. At this time, the tool retracting from the induction coil 6 is still at a high temperature. The worker places a receiving container on the right side of the support plate 3 beforehand, then pushes the mounting rod 4 to move it to the right relative to the vertical slider 35, compressing the elastic element 401. This causes the L-shaped block 5 to push the tool from the support plate 3 to the right into the container. When the mounting rod 4 is opened, the elastic element 401 extends and pushes the mounting rod 4 to reset the L-shaped block 5. Then, the next tool holder and blade are placed on the support plate 3 and positioned by the L-shaped block 5. After that, the left mounting plate 21, right mounting plate 22, support plate 3, mounting rod 4 and L-shaped block 5 are moved to the left so that the new tool holder and blade are located inside the induction coil 6, and welding can continue. After the tool holder and blade are located inside the induction coil 6, the shielding cover 7 moves to the left with the left mounting plate 21 and moves away from the induction coil 6, allowing the worker to check the welding situation inside the induction coil 6.

[0030] Furthermore, as the brazing filler metal and flux melt, their volume changes, causing the blade within the tool holder groove to easily shift. Therefore, after the tool holder, blade, brazing filler metal, and flux are placed, the worker pulls the extrusion plate 10, which in turn stretches the rubber band 9. The extrusion plate 10 is then placed against the right side of the tool holder. The tension of the rubber band 9 forces the extrusion plate 10 to press against the tool holder, squeezing the tool holder towards the L-shaped block 5. Consequently, the tool holder presses the blade firmly against the L-shaped block 5. During subsequent welding, the blade restricts the molten brazing filler metal and flux, preventing the blade from shifting due to their influence. Simultaneously, depending on the tool holder length, the worker can move the mounting block 8 upwards to separate it from the right mounting plate 22. Then, a suitable adjustment groove 801 is selected and re-engaged with the limiting groove 203 to adjust the relative position of the mounting block 8 and the right mounting plate 22. This changes the position of the extrusion plate 10 after the rubber band 9 is stretched to its limit, accommodating tool holders of various lengths.

[0031] Furthermore, during the welding process, a small amount of molten brazing filler metal and flux, as well as the oxide layer on the tool holder, are prone to falling off. After the molten brazing filler metal and flux mix with the oxide layer and cool, they become hard lumps that adhere to the support plate 3, affecting the flatness of the support plate 3 and consequently affecting the placement of the tool holder. Therefore, after a large number of hard lumps adhere to the support plate 3, the worker first lifts the right side of the support plate 3 upwards, disengaging the slot 301 from the locking block 202. Then, the support plate 3 is moved to the right, causing the left end of the support plate 3 to detach from the insertion block 201. The support plate 3 is then quickly removed from the left mounting plate 21 and the right mounting plate 22. Afterward, the support plate 3 is tapped to shake off and remove the hard lumps adhering to it. The support plate 3 can then be reinstalled for use.

[0032] Based on the above steps, we can see that the present invention has the following effects: Adjust the mounting rod 4 and L-block 5 to fit the tool according to its size. Then, use the L-block 5 to position and limit the tool holder. This ensures welding quality during welding. When welding the same tool in the future, you only need to place the tool and workpiece in place. There is no need to readjust the mounting rod 4 and L-block 5. Only the initial adjustment is required. The tool can be used multiple times, improving welding continuity and efficiency.

[0033] Although the induction coil 6 itself does not generate heat, the cutting tool heats up rapidly under electromagnetic induction, and its temperature radiates heat to the induction coil 6, making the induction coil 6 hot. Then, the shield 7 covers the induction coil 6 when the cutting tool is loaded and unloaded, preventing workers from accidentally touching the induction coil 6 and getting burned. When welding, the shield 7 moves with the left mounting plate 21 and moves away from the induction coil 6, allowing workers to check the welding condition inside the induction coil 6.

[0034] The rubber band 9 drives the extrusion plate 10 to press the tool holder against the L-shaped block 5, thereby pressing the blade onto the L-shaped block 5. During subsequent welding, the blade restricts the molten brazing filler metal and flux, preventing the blade from being displaced due to the influence of the brazing filler metal and flux.

[0035] The support plate 3 is connected to the left mounting plate 21 and the right mounting plate 22 by a snap-fit ​​connection. If there are many hard lumps adhering to the support plate 3 and they affect the placement of the tool, the support plate 3 can be quickly removed and tapped to shake off and remove the hard lumps. Then the support plate 3 can be reinstalled for use.

[0036] Example 2: Based on Example 1, such as Figure 3 As shown, it also includes a blocking edge 302; a blocking edge 302 is provided on each of the long sides of the support plate 3.

[0037] The operation steps for using this embodiment are as follows: When the support plate 3 passes through the induction coil 6, the solder, flux, and oxides that fall on it are likely to fall from the edge onto the induction coil 6, affecting the electromagnetic induction function of the induction coil 6. The induction coil 6 also has heat due to the heat radiation from the cutting tool, making it inconvenient to clean during the welding process. To improve work efficiency, a blocking edge 302 is set at the edge of the support plate 3 to prevent the solder, flux, and oxides on the support plate 3 from falling onto the induction coil 6 before cleaning the support plate 3, thus affecting the electromagnetic induction function of the induction coil 6.

[0038] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
