Description

Technical Field

[0001] This invention relates to the field of kitchen knife welding technology, and more particularly to an automatic welding machine for kitchen knife blanks. Background Technology

[0002] Kitchen knives are common cutlery in daily life. With social development, knife manufacturing has shifted from handmade to factory production, adhering to the principle of "using good steel for the blade." Factory production divides knives into three parts: the blade, the cutting edge, and the handle. The blade, cutting edge, and handle are first made separately, then welded together to form a knife blank. The knife blank then undergoes a series of polishing processes to form the final knife.

[0003] In existing technologies, the blade blank welding process involves using specialized tooling or fixtures to fix the various components of the blade blank, which are then manually welded together by a welder to form the blade blank. The disadvantages of manual welding are: low efficiency, inconsistent quality, and significant health risks to the welder from welding radiation. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention proposes an automatic welding machine for kitchen knife blanks that can automatically weld the blade, blade body and handle into a knife blank.

[0006] The main unit cabinet houses the PLC control system and the welding main unit. The main unit housing is mounted on the cabinet, with an opening on one longitudinal side. An X-axis linear module is mounted on the cabinet, located inside the housing, and extends longitudinally through the opening. A Z-axis linear module is located on the transverse side of the X-axis linear module, at one end of the X-axis linear module within the housing, and is distributed vertically. Two Y-axis linear modules are provided, each located on the longitudinal side of the Z-axis linear module near the opening, and are distributed transversely, symmetrical about the Z-axis linear module. Two welding torches are slidably mounted on each of the two Y-axis linear modules, sliding in the same direction or opposite directions. The welding main unit is connected to the welding torches. The PLC control system is connected to the X-axis, Z-axis, and Y-axis linear modules. A switch is mounted on the cabinet and is connected to both the PLC control system and the welding main unit. A mounting bracket is slidably mounted on the X-axis linear module.

[0007] The mounting bracket includes a mounting plate b and a side plate. The mounting plate b is slidably mounted on the X-axis linear module. The side plate is located on the lateral side of the mounting plate b near the Z-axis linear module. The lateral side of the side plate near the Z-axis linear module is provided with a fixture for fixing the tool blank. Multiple permanent magnets are embedded in the fixture.

[0008] Preferably, it also includes reinforcing ribs; the reinforcing ribs are disposed between the mounting plate b and the side plate, the reinforcing ribs are triangular in structure, and weight-reducing holes are provided inside the reinforcing ribs.

[0009] Preferably, the tooling is provided with multiple locking blocks for limiting the movement of the tool blank.

The main unit placement cabinet 1 houses a PLC control system and a welding main unit. The machine housing 2 is mounted on the main unit placement cabinet 1, and an opening 201 is provided on one longitudinal side of the machine housing 2. The protective door 3 is slidably mounted on the machine housing 2, and is located within the opening 201. By providing the protective door 3, it can be closed during the welding of the knife blank, providing good protection for the workers. The X-axis linear module 4 is mounted on the main unit placement cabinet 1, and is located within the machine housing 2. The X-axis linear module 4 extends longitudinally through the opening 201 and includes a slider a401. The Z-axis linear module 5 is mounted on one transverse side of the X-axis linear module 4, and is located at one end of the X-axis linear module 4 within the machine housing 2. Module 5 is distributed vertically; two Y-axis linear modules 6 are provided, both located on the longitudinal side of the Z-axis linear module 5 near the opening 201, and are distributed laterally, symmetrical about the Z-axis linear module 5. Each Y-axis linear module 6 includes a slider b601; two welding torches 8 are slidably mounted on each of the two Y-axis linear modules 6, sliding in the same direction or opposite directions. A mounting plate a7 is provided at the bottom of each welding torch 8, mounted on the slider b601. The mounting plate a7 and slider b601 are detachably connected, facilitating the installation and removal of the welding torches 8; the welding host is controlled and connected to the welding torches 8; the PLC control system is controlled and connected to the X-axis linear module 4, Z-axis linear module 5, and Y-axis linear module 6; a switch 20 is located on the host placement cabinet 1, and is controlled and connected to both the PLC control system and the welding host; a mounting bracket 9 is slidably mounted on the X-axis linear module 4.

[0023] Mounting bracket 9 includes mounting plate b10, reinforcing rib 11, and side plate 12. Mounting plate b10 is slidably mounted on X-axis linear module 4 and mounted on slider a401. Mounting plate b10 and slider a401 are detachably connected, facilitating disassembly of the mounting side of mounting bracket 9. Side plate 12 is located on the lateral side of mounting plate b10 near Z-axis linear module 5. A fixture 13 for fixing the tool blank is provided on the lateral side of side plate 12 near Z-axis linear module 5. Multiple permanent magnets 1301 are embedded in the fixture 13, and multiple locking blocks for limiting the movement of the tool blank are provided on the fixture 13. 14. It can restrict the cutting edge 15, the cutting body 16 and the handle 17 that are attached to the tooling 13, ensuring the precise positioning of the cutting edge 15, the cutting body 16 and the handle 17, thereby improving the welding accuracy of the cutting blank; the reinforcing rib 11 is set between the mounting plate b10 and the side plate 12. The reinforcing rib 11 has a triangular structure. The triangular reinforcing rib 11 can improve the stability of the connection between the side plate 12 and the mounting plate b10. The reinforcing rib 11 is provided with weight reduction holes. The weight reduction holes on the reinforcing rib 11 can effectively reduce the weight of the mounting bracket 9, reduce the energy required to move the mounting bracket and save resources.

[0024] In use, the operator programs the PLC control system, then starts the PLC control system via a switch, causing it to control the X-axis linear module 4 to push the mounting bracket 9 to the loading / unloading station B outside the housing 2. The operator then installs the blade 15, blade body 16, and handle 17 into the corresponding positions on the fixture 13. Multiple permanent magnets 1301 attract the iron blade 15, blade body 16, and handle 17, while multiple locking blocks 14 limit their movement. Finally, the PLC control system controls the mounting bracket 9 to move the workpiece to be welded. The blade 15, blade body 16, and handle 17 are brought to welding station A inside the machine housing 2. At this time, the operator starts the PLC control system and welding host via switch 20. The welding host controls two welding torches 8 to perform welding. The PLC control system, through a computer program, controls the X-axis linear module 4, Z-axis linear module 5, and Y-axis linear module 6 to move the mounting bracket 9 and welding torches 8 to complete the welding of both sides of the blade blank. After welding, the X-axis linear module 4 pushes the mounting bracket 9 to loading / unloading station B, where the operator unloads the blade blank, thus achieving automatic welding of the blade blank. This invention significantly improves the welding efficiency and quality of the blade blank, while reducing the harm of welding radiation to the welder. It also lowers the requirements for welders, making it easier for factories to recruit welding workers. Furthermore, it causes no environmental pollution, thereby saving production costs and enhancing the market competitiveness of the cutting tools.
