Technical Field

[0001] The invention belongs to the technical field of wire cutting equipment, and in particular relates to a double-layer wire cutting equipment and a use method thereof. Background Art

[0002] Wire cutting is a precision metal processing technology that uses the principle of electric spark discharge to cut metal workpieces through thin metal wires (usually copper wires or molybdenum wires) as electrodes. This processing method is mainly suitable for workpieces with high hardness, brittleness or complex shapes, and can accurately achieve complex cutting shapes, especially for materials that are difficult to process by traditional mechanical processing methods. Wire cutting can achieve very high processing accuracy, and the error can usually be controlled within ±0.02 mm, or even higher accuracy (±0.005 mm). This high precision makes it an ideal choice for precision parts processing, especially in mold manufacturing, precision machinery and other fields.

[0003] When existing wire cutting equipment is used to cut parts, the worker first manually threads the cutting wire so that the cutting wire passes through the parts. After the parts are cut, the parts automatically fall onto the processing rack. However, during this process, the cut parts may break the cutting wire, causing the wire cutting equipment to be unable to operate normally. The worker needs to stop the machine and rethread the wire, which greatly reduces work efficiency. Summary of the invention

[0006] The front and rear ends of the top of the processing frame are fixedly connected to mounting frames, a movable frame is slidably connected between the two mounting frames, and a first moving component is installed between the movable frame and one of the mounting frames;

[0007] A second moving assembly is installed on the movable frame, a connecting frame is installed on the second moving assembly, a wire cutting mechanism is installed between the connecting frame and the movable frame, and supporting mechanisms are installed at the front and rear ends of the bottom of the processing frame.

[0008] Furthermore, the clamping mechanism includes a fixing frame fixedly connected to the front and rear ends of the top of the processing frame, a plurality of first mounting holes are opened on the top of the two fixing frames, a double-layer frame is provided between the tops of the two fixing frames, a plurality of second mounting holes are opened on the double-layer frame, a plurality of first bolts are provided on the double-layer frame, a clamping block is provided at the center of the outer wall of the plurality of first bolts, the top ends of the outer walls of the plurality of first bolts are threadedly connected with first nuts, two second bolts are provided between the double-layer frame and the two fixing frames, and the top ends of the outer walls of the plurality of second bolts are threadedly connected with second nuts.

[0009] Through the above technical solution, when clamping two parts, the two parts are first placed on the double-layer rack respectively, and according to the size of the parts, multiple first bolts are passed through the corresponding second mounting holes, and then multiple clamping blocks are placed on the corresponding first bolts and tightly attached to the tops of the corresponding parts, and then multiple first nuts are threadedly connected to the corresponding first bolts to achieve clamping of the two parts. Two parts can be clamped at one time, and parts of different specifications and sizes can be clamped, with strong functionality.

[0010] Furthermore, a plurality of the second bolts respectively penetrate the corresponding first mounting holes.

[0012] Furthermore, the connecting frame is slidably connected to the movable frame.

[0013] Through the above technical solution, when cutting parts, the first movable assembly and the second movable assembly are both running. According to the size of the parts to be cut, the first movable assembly and the second movable assembly drive the cutting mechanism to move forward, backward, left and right, thereby cutting the designed shape in the two parts.

[0014] Furthermore, the wire cutting mechanism includes a fixed seat fixedly connected to the top center of the movable frame, the top of the fixed seat is rotatably connected to a wire reel, a plurality of guide wheels are installed on one side of the connecting frame, and a cutting wire is wound between the plurality of guide wheels and the wire reel.

[0015] Through the above technical solution, before cutting the parts, one end of the cutting wire is passed through two parts, then wound around a plurality of guide wheels, and finally tightened and fixed on the wire drum.

When the part is cut off, it falls onto the two material receiving racks to prevent the cut part from breaking the cutting line. This not only protects the cutting line, but also eliminates the need for re-threading, greatly improving the processing efficiency.

[0018] Furthermore, the gear is meshed with the rack, and according to the installation position of the double-layer rack, the motor is started, and the output shaft rotates to drive the gear to rotate, thereby driving the two support plates to move to the specified position.

[0022] Step 3: When cutting the parts, both the first moving assembly and the second moving assembly are running. According to the size of the parts to be cut, the first moving assembly and the second moving assembly drive the cutting line to move forward, backward, left and right, so as to cut the designed shape in the two parts;

[0023] Step 4: When the parts are about to be cut off, start the two cylinders, and push the connected receiving racks through the pistons, so that the two receiving racks are close to each other. At this time, every two movable grooves are combined to form a rectangular groove, which is equivalent to the final cutting path of the cutting line.
