Description

Technical Field

[0001] The present invention relates to the technical field of tool processing, and specifically to a control system for a tool edge-opening and rabbeting equipment. Background Art

[0002] When a tool is calcined, the iron or steel on its surface will oxidize or have a high carbon content, making it brittle. The so-called edge-opening is to grind off impurities such as iron oxide at the edge of the tool to expose the steel part, so that the tool will be sharper. However, existing tools all adopt the method of manual edge-opening, which cannot ensure that the tool edge angle is 24°±4 and the sharpness is 3 knives at 80 mm and 60 knives at 300 mm according to the standard. The human influence is relatively large. Moreover, the tool rabbeting process also requires an old master with many years of experience to operate manually, and the human influence is also relatively large, which is time-consuming and laborious, and the processing efficiency is low.

[0040] Working principle: Refer to Figures 7 - 10 , and please combine with the patent of a tool edge-opening and rabbeting equipment applied by our company. This system is used in conjunction with the tool edge-opening and rabbeting equipment:

[0041] When performing edge-opening processing, first perform edge-opening machine adjustment: Place the tool on the edge-opening positioning fixture and clamp it. Then press the cylinder control button to clamp the profiling tool. Debug the starting position data of the first point of the profiling tool's grinding and save the position data. Then control the Y-axis edge-opening module to move to the processing end position data of the profiling tool. The system will take 50 points according to the tool length, automatically generate processing data, and then click to save the data. Then place the tool to be processed on the Y1 (i.e., the Y-axis edge-opening module) axis with a fixture positioning point, and press the cylinder control button to clamp the processing tool. Adjust the processing angle of the left high-speed motor by 12°, and then adjust the processing angle of the right high-speed motor by 12°. Install the required roughness resin diamond grinding wheel. Left edge debugging: Control the Y1 axis, press the starting position data of the first point of the profiling tool's grinding that has been debugged, adjust the feed amount of the left high-speed motor's Z-axis until it reaches 60% of the edge thickness of the processing tool, and then control the Y-axis servo module to move to the processing end position data of the profiling tool to end the left processing. Right edge debugging: Then control the Y1 axis, press the starting position data of the first point of the profiling tool's grinding that has been debugged, adjust the feed amount of the right high-speed motor's Z-axis until it reaches 50% of the edge thickness of the processing tool, and then control the Y-axis servo module to move to the processing end position data of the profiling tool to end the left processing. Save the debugged data to the PLC controller (this system can save 70 processing data, and when making the same model product later, the processing data can be directly called).

[0042] When performing rabbeting processing, first conduct rabbeting debugging: First, place the profiling tool for the tool piece to be processed on the fixture positioning of the profiling module, then press the air cylinder control button to clamp the profiling tool, debug the starting position data of the first point of the profiling tool's grinding, and then control the Y-axis rabbeting module to move to the processing end position data of the profiling tool. Then, place the tool to be processed on the Y2 axis (i.e., the Y-axis rabbeting module) at the fixture positioning point, and press the air cylinder control button to clamp the processing tool. Adjust the machining feed rate and pressing force of the left high-speed motor, then adjust the machining feed rate and pressing force of the right high-speed motor, install the required green wax, and adjust the wax application times. Left-side rabbeting debugging: Control the Y2 axis, press the saved position data of the starting position of the first point of the profiling tool's grinding, adjust the feed amount of the left high-speed motor's Z axis until it reaches the pressing number of the tool edge of the processed tool, and then control the Y-axis servo module to move to the processing end position data of the profiling tool to end the left-side processing. Right-side rabbeting debugging: Then control the Y2 axis, press the saved position data of the starting position of the first point of the profiling tool's grinding, adjust the feed amount of the right high-speed motor's Z axis until it reaches the pressing number of the tool edge thickness of the processed tool, and then control the Y-axis servo module to move to the processing end position data of the profiling tool to end the left-side processing. Save the above debugging data to the PLC. (This system can save 70 processing data, and when making the same model products later, the processing data can be directly called); Try machining the tool according to the saved data. If it is qualified, mass production can be carried out. If the tool edge is not opened clearly, just adjust the machining feed amount. After passing the inspection, adjust and save the data; After the machine is adjusted to be qualified, place the tool to be processed on the Y axis at the fixture positioning point, press the air cylinder control button to clamp the processing tool, and press the green start button to start the processing. During the processing, the grinding coolant will be automatically sprayed and recycled, and the processing will automatically stop after completion. The iron powder processed will be separated by a magnetic separator to prevent the product surface from being sprayed with flowers.

[0043] When processing products, a large amount of water mist will be generated, and an automatic exhaust fan is used to extract the water mist. For every 5 products processed, the system replenishes 0.005 mm to ensure the product processing volume. When replacing the resin diamond grinding wheel, the feed rate needs to be adjusted again. Tool edge-opening production: After all the debugging is completed, import the saved data such as "S632 - 8-inch chef". Place the tool to be edge-opened on the Y1 axis at the fixture positioning point. Press the cylinder control button (clamping tool 1) to clamp the tool to be edge-opened, and then press (start 1) to start automatic edge-opening. After the processing is completed, the cylinder will automatically open, and the operator can manually remove the edge-opened tool. Then, repeat the production according to the previous operation. Tool grooving production: After all the debugging is completed, import the saved data such as "S632 - 8-inch chef". Place the tool to be grooved on the Y2 axis at the fixture positioning point. Press the cylinder control button (clamping tool 2) to clamp the tool to be grooved, and then press (start 2) to start automatic grooving. After the processing is completed, the cylinder will automatically open, and the operator can manually remove the grooved tool. Then, repeat the production according to the previous operation. When replacing products with smaller sizes, the clamping tool fixture needs to be replaced and re-debugged.

[0044] In summary, the control system of this tool edge-opening and grooving equipment has a high level of automation, little human influence, and high processing efficiency.
