Description

Technical Field

[0001] The present application belongs to the technical field of machine tool auxiliary equipment, and in particular, relates to a loading and unloading device, a wire cutting machine using the device, and a wire cutting method. Background Art

[0002] Wire cutting refers to cutting raw materials (conductive materials) with linear tools (such as metal wire, molybdenum wire, etc.). The wire cutting machine is mainly composed of a machine tool, a CNC system and a high-frequency power supply. The machine tool consists of a bed, a wire storage mechanism, a wire rack, an XY workbench and other components. The molybdenum wire wound on the wire storage cylinder moves back and forth at high speed through the wire rack to process the workpiece.

[0003] With the rapid development of society and the continuous advancement of science and technology, people are constantly pursuing faster and better work efficiency, and quality requirements are gradually increasing. In view of the current status of wire cutting processing of CNC turning blade base (hereinafter referred to as blade base), operators need to cooperate with the machine to repeatedly manually remove the blade base. After each cutting is completed, the blade that has been cut needs to be manually removed and another batch of blades to be cut needs to be reinstalled and pressed. This process is extremely time-consuming and labor-intensive, with high labor costs, and labor efficiency needs to be improved, resulting in low cutting efficiency. The cutting quality will vary with the quality of manual removal of the blade base and installation of the blade base.

[0004] With regard to the above-mentioned related technologies, there are many manual work processes, which are inefficient and it is difficult to ensure the consistency of cutting quality. Summary of the invention

[0005] In order to simplify the work process, improve work efficiency, and enhance the reliability of cutting quality, the present application provides a wire cutting machine and a wire cutting method.

[0006] In a first aspect, the present application provides a loading and unloading device, which adopts the following technical solution.

[0007] A loading and unloading device comprises a first slide rail and a second slide rail, wherein the first slide rail is provided with an X-axis slide rail (25), the X-axis slide rail (25) is provided with a second driving and material carrying assembly (3), the second slide rail is provided with a pressing and rotating assembly (7), and the X-axis slide rail (25) is used to exchange objects to be cut with the pressing and rotating assembly (7);

[0008] The material carrying assembly (3) comprises a first drive, a clamping cylinder and a clamping claw;

[0009] The pressing and rotating assembly (7) comprises a third drive, a second rotating plate (72) and a pressing structure.

[0010] By adopting the above technical scheme, the material carrying component grabs the object to be cut through the clamping cylinder and the clamping claw, which is convenient for clamping the object to be cut without manual operation by the staff; the first drive causes the clamping cylinder to move along the X-axis slide rail to the pressing and turning component, and the clamping structure of the pressing and turning component presses the object to be cut onto the second rotating plate, and the loading process is completed through the material carrying component to achieve more favorable clamping; the second rotating plate can move on the second slide rail, and by moving the second slide rail, the object to be cut is moved to the linear tool of the frame, saving positioning time, saving loading and unloading time, and making the cutting position more accurate to complete efficient cutting and ensure consistency of cutting quality.

[0011] Optionally, a positioning column is fixed on one side of the second rotating plate, and a clamping cylinder and a limiting cylinder are provided on the other side. The second rotating plate is provided with an avoidance hole and a clamping hole. The piston end of the clamping cylinder passes through the clamping hole to connect to the pressure rod, the piston end of the limiting cylinder is connected to the avoidance cylinder, and the piston end of the avoidance cylinder is connected to the avoidance column. The avoidance column can pass through the avoidance hole from the side of the second rotating plate away from the positioning column to exit the second rotating plate.

[0012] By adopting the above technical scheme, the position of the object to be cut can be limited by the positioning column fixed on the second rotary plate, and the avoidance cylinder will prevent the avoidance column from extending out of the plane where the positioning column of the second rotary plate is located during the loading process of the material carrying component. After the material carrying component limits the object to be cut within a specific range of the positioning column, the avoidance cylinder drives the avoidance column to extend, limits the position of the object to be cut in another direction, and then the object to be cut is confined between the pressure rod and the second rotary plate by the pressure rod, thereby achieving precise positioning and effective fixation, preventing inaccurate cutting position due to insufficient pressing of the material, improving work efficiency, and ensuring consistency in cutting quality.

[0013] Optionally, the pressure-rotation assembly further includes a second rotating cylinder, which is slidably connected to the second Y-axis slide rail, and the rotating end of the rotating cylinder is connected to a side of the second rotating plate away from the positioning column.

[0014] By adopting the above technical solution, the material carrying component limits the object to be cut at the positioning column through the action of gravity. The action of gravity is relatively reliable and can accurately limit the object to be cut within the positioning column. At this time, the object to be cut is a row of horizontally arranged cemented carbide substrates. After being pressed together by the avoidance cylinder and the avoidance column, the whole is rotated 90°, so that the originally horizontally arranged metal substrates are arranged in the vertical direction, which is in line with the movement direction of the molybdenum wire to achieve cutting.

[0015] Optionally, the material carrying assembly (3) includes an X / Z servo motor, an X / Z axis slide (31), a first rotating cylinder (32), a clamping cylinder and a clamping claw, wherein the X / Z servo motor is connected to the rotating cylinder, and the first rotating cylinder (32) can move along the X-axis slide (25) direction and / or the Z-axis direction under the drive of the X / Z servo motor, the rotating end of the first rotating cylinder (32) is connected to the clamping cylinder, and the clamping claw is connected to the piston end of the clamping cylinder.

[0016] By adopting the above technical solution, the material carrying component lifts the clamped object and moves along the X-axis direction to the pressing and turning component. The material loading process from the material carrying component to the cutting is realized quickly and accurately; the clamping claws of the material carrying component and the positioning column of the pressing and turning component are conveniently connected, accurate positioning is achieved, work efficiency is improved, and consistency of cutting quality is ensured.

[0017] Optionally, the wire cutting machine further comprises a material loading and unloading assembly, wherein the material carrying assembly comprises a material storage bracket, a material grid and a lifting motor, wherein a piston end of the lifting motor passes through a top wall of the material storage bracket and is connected to the material grid.

[0018] By adopting the above technical solution, automatic loading and unloading of multiple material trays can be achieved. There is no need to manually place the material trays in the clampable position of the clamping claws, and there is no need to manually collect the cut material trays after cutting is completed, thereby improving the molybdenum wire cutting efficiency.

[0019] Optionally, the material grid has multiple layers, and a discharging cylinder is provided on one side of the frame close to the material grid, and a feeding cylinder is provided on the other side.

[0020] By adopting the above technical solution, the cutting volume of a batch of cutting is increased, large-scale production without stopping the machine is achieved, and work efficiency is improved.

[0021] Optionally, there are two clamping cylinders, and the piston ends of the two cylinders are vertically arranged.

[0022] By adopting the above technical solution, two groups of objects to be cut are grabbed. When the molybdenum wire cuts the first group of objects to be cut, the material carrying assembly waits on the side. When the first group of objects to be cut is cut, the material carrying assembly takes the first group away, and then fixes the second group in the same way, rotates the second rotary plate, and performs the second cutting, thereby achieving uninterrupted production and improving cutting efficiency. The vertical setting reduces the switching time of the two groups of clamping positions, further improving work efficiency. In the second aspect, the present application provides a wire cutting machine, including a frame and molybdenum wire. The above loading and unloading device is used on the frame platform to realize automatic loading and unloading to complete wire cutting.

[0023] In a third aspect, the present application provides a wire cutting method, which adopts the following technical solution.

[0024] A wire cutting method comprises the following steps:

[0025] S1: grab two groups of objects to be cut;

[0026] S2: transport one of the groups to the compression assembly for compaction;

[0027] S3: Rotate the pressing assembly to make the cutting direction of the object to be cut the same as the direction of the molybdenum wire;

[0028] S4: start and complete cutting of a group of objects to be cut;

[0029] S5: Rotate the pressing and turning assembly to remove the cut objects and replace them with another set of uncut objects to be cut;

[0030] S6: while starting to cut the second group of objects to be cut, put back the cut objects, clamp another group of objects to be cut and return them to the pressing and turning assembly, waiting for the completion of the second group of cutting.

[0031] By adopting the above technical scheme, the material carrying component grabs the object to be cut through the clamping cylinder and the clamping claw, which is convenient for clamping the object to be cut without manual operation by the staff. The first drive causes the clamping cylinder to move along the X-axis slide rail to the pressing and turning component. The clamping structure of the pressing and turning component presses the object to be cut onto the second rotating plate. The loading process is completed through the material carrying component to achieve more favorable clamping. The second rotating plate can move on the second slide rail. By moving the second slide rail, the object to be cut is moved to the linear tool of the frame, saving positioning time, saving loading and unloading time, and making the cutting position more accurate to complete efficient cutting and ensure consistency in cutting quality.

[0032] Optionally, a discharging process is included before S1, and a feeding process is included after S6;

[0033] The discharging process is that the discharging cylinder pushes the material tray from the material grid to the position to be clamped;

[0034] The feeding process is that the feeding cylinder pushes the material tray from the to-be-clamped station into the material grid.

[0035] By adopting the above technical solution, automatic loading and unloading of multiple material trays can be achieved. There is no need to manually place the material trays in the clampable position of the clamping claws, and there is no need to manually collect the cut material trays after cutting is completed, thereby improving the molybdenum wire cutting efficiency.

[0036] In summary, this application has the following beneficial technical effects.

[0037] The present application has a mechanical loading and unloading structure. There is no need to manually disassemble the blade substrate to be cut that has completed wire cutting, nor is there a need to manually install the blade substrate to be cut. The present application can be used with a CNC system to set the CNC process, complete debugging, and the mechanical structure automatically locks the blade substrate to be cut and cuts. For double-head (two tips of the blade) wire cutting, after the molybdenum wire cuts one end of the blade substrate, move the molybdenum wire to the other end for cutting; for double-sided (two planes of the blade) substrate processing, it is only necessary to rotate the substrate to be processed 180° in the horizontal direction and load it into the material tray for automatic positioning and cutting again. Therefore, this device greatly reduces the time cost caused by disassembling the substrate for cutting and processing of various blade substrates. For batch repetitive operations of standard products, it greatly improves production efficiency and reduces labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

When the blade base 6 is located at the upper end of the pressing and turning assembly 7, loading is achieved.

[0055] Reference Figure 5 The pressing and rotating assembly 7 includes a second rotating cylinder 71 , a second rotating plate 72 , a pressing cylinder 73 , an avoidance cylinder 74 , a positioning column 75 , an avoidance column 76 , a pressing rod 77 and a limiting cylinder 78 .

[0059] The second rotating plate 72 is rotated 90° as a whole, with the surface to be cut in the vertical direction, and is moved to the molybdenum wire 12 to achieve cutting of the blade base 6 .

[0060] Example 2

[0061] The embodiment of the present application discloses a wire cutting method, which includes the following steps.

[0062] 1. Discharging: the discharging cylinder 41 pushes the material tray 5 from the material grid 43 to the position to be clamped;

[0063] 2. Grab two sets of blade substrates as the objects to be cut;

[0064] 3. Transport one group to the pressing and turning assembly 7 for compaction;

[0065] 4. Rotate the pressing assembly 7 to make the cutting direction of the object to be cut the same as the direction of the molybdenum wire 12;

[0066] 5. Start and complete the cutting of a set of objects to be cut;

[0067] 6. Rotate the pressing assembly 7, remove the blade substrate that has been cut, and replace it with another set of uncut blade substrates;

[0068] 7. When the second set of blades starts cutting the base, put back the cut objects, clamp another set of objects to be cut and return them to the pressing and turning assembly 7, waiting for the second set of cutting to be completed;

[0069] 8. Feeding: the feeding cylinder 46 pushes the material tray 5 from the to-be-clamped station into the material grid 43.

[0070] Operation process:

[0071] The blade substrates 6 to be cut are placed in order on the material tray 5 and loaded into the material grid 43. The material tray 5 is lifted and lowered by the lifting cylinder 45. The discharging cylinder 41 pushes the material tray 5 to the workbench of the frame 11. The second driving motor drives the first Y-axis slide 23 to move, so that the material carrying assembly 3 arranged on it moves just above the material tray 5 with the blade substrates 6 to be cut. At this time, the discharging of the blade substrates 6 to be cut is completed.

[0072] When the blade substrate 6 to be cut is directly below the material carrying assembly 3, the clamping claw in the material carrying assembly 3 works, and it drops to a suitable height. The clamping cylinder grabs the blade substrate 6 to be cut into the clamping claw. In this embodiment, three substrates are grabbed at one time. In order to prevent the clamping claw from being too strong during the grabbing process, causing the blade substrate to collapse, an elastic buffer sheet is set at the position close to the blade substrate 6 on the inner side of the clamping claw. After the grabbing is completed, the clamping claw rises a small distance, and the rotating cylinder works, and the other pair of clamping claws are turned to the top of the blade substrate 6 to be cut, and the last grabbing process is repeated. After the blade substrate 6 is grasped, the material carrying assembly 3 moves to the top of the pressing assembly 7 on the X-axis slide rail 25. That is, the first rotating cylinder (32) is driven by the X / Z servo motor to first lift and lower along the Z-axis direction to assist in completing the loading and unloading process, and then moves back and forth along the X-axis slide rail (25) to complete the material handover.

[0073] When the blade substrate 6 to be cut moves to just above the pressing and turning assembly 7, the blade substrate to be cut descends to the position of the positioning column 75 of the pressing and turning assembly 7 and is stuck between the two positioning columns 75. The avoidance cylinder 74 works, the avoidance column 76 extends, the limit cylinder 78 works, the avoidance column 76 descends, and the blade substrate 6 to be cut is vertically positioned on the second rotating plate 72. The clamping cylinder 73 works, and the pressure rod 77, under the action of the clamping cylinder 73, firmly presses the blade substrate 6 to be cut on the second rotating plate 72. In order to prevent the blade substrate 6 from collapsing due to excessive force during clamping, an elastic buffer sheet is correspondingly provided on the inner side of the pressure rod 77. At this time, the clamping of the substrate to be cut is completed.

[0074] When the blade base 6 is clamped, the second rotating cylinder 71 works to rotate the blade base 6 to be cut in the pressing and turning module by 90°, so that the side of the blade base 6 to be cut is close to the wire-cut molybdenum wire 12, and the second Y-axis slide 24 is moved on the second Y-axis slide rail 22 to move the pressing and turning assembly 7 to the cutting area of ​​the molybdenum wire 12 for cutting.

[0075] After the cutting is completed, the molybdenum wire 12 can also cut the other side of the blade matrix 6, and repeat the cutting process. After the cutting of both sides of the blade matrix 6 is completed, the second rotary cylinder 71 works, and the blade matrix 6 to be cut is reversely rotated 90° to restore the previous position, the pressing block is released, and the avoidance column 76 is retracted into the second rotating plate 72. The clamp descends to grab the cut blade matrix 6, and after rising a short distance, it rotates 90°, and the blade matrix 6 to be cut on the other set of clamps is clamped in the pressing and turning assembly 7 in the same way as before. At this time, the following two steps are carried out simultaneously: 1. The clamp returns to the top of the material tray 5, puts the cut blade matrix 6 back to the material tray 5 along the original route, and then grabs the third group of blade matrices 6 to be cut, repeats the previous steps, and waits for cutting; 2. The pressing and turning wood block performs the wire cutting process of the second group of blade matrices 6 to be cut. The above overall process is repeated until all the blade matrices 6 to be cut are completely cut and returned to the material grid 43.

[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, all equivalent changes made according to the structure, structure, and principle of the present application should be included in the protection scope of the present application.
