Description
Technical Field
[0001] The present invention relates to the technical field of filter cover plate processing, and in particular to a filter cover plate processing device and method. Background Art
[0002] A filter is a frequency-selective device that allows specific frequency components in a signal to pass through while greatly attenuating other frequency components. The frequency-selective function of the filter can be used to filter out interference noise or perform spectrum analysis. The filter cover is an important component of the filter and is usually located on the top of the filter. It is used to close the internal space of the filter and protect the internal circuits and components from external interference. It also has the function of adjusting the filter performance. Since the filter cover is made of metal material, it is usually formed by stamping.
[0003] Deficiencies in the prior art: Since different filter cover plates have different thicknesses, the processing equipment used for filter cover plates in the prior art cannot adjust the stamping depth according to the filter cover plates of different thicknesses, which can easily cause the cover plates to deform or the stamping to be incomplete, resulting in processing errors. At the same time, during the stamping process, the friction between the mold and the workpiece and the plastic deformation of the workpiece will cause a large amount of heat to be generated. Excessive temperature will soften the processed material and cause it to adhere to the surface of the punch head or mold. Repeated cycles will cause increased wear of the equipment and reduce its service life. Summary of the invention

[0014] Preferably, a support frame is fixedly mounted on one end of the workbench, and a conveyor is arranged in the middle of the support frame.
[0015] The present invention also provides a method for processing filter cover plate equipment, comprising the following steps:
[0016] Step 1: According to the thickness of the plate, the height of the first limit block is adjusted by the hydraulic push rod. After the adjustment is completed, the braking device is started, and the braking device drives the punch slider to slide downward on the surface of the guide rail.

When the extended end of the hydraulic cylinder is extended to the longest, the stamping table tilts, and the cover plate at the top will slide to the top of the conveyor and be transmitted to the next process.
[0020] Technical effects and advantages of the present invention:
[0021] 1. The present invention adjusts the stamping depth of the processing equipment by providing a first limit block and a second limit block. According to the thickness of the plate to be processed, the height of the first limit block is adjusted by a hydraulic push rod. During the stamping process, when the second limit block drops to the top of the first limit block, the punch slider stops descending, and the plate is stamped by the stamping template to complete the processing of the cover plate, thereby ensuring the accuracy of the cover plate size and avoiding deformation of the cover plate or incomplete stamping. At the same time, before the second limit block drops to the first limit block, the fixed block first contacts the top of the plate to fix the position of the plate, thereby avoiding the position of the plate from shifting during stamping, resulting in inaccurate stamping position and the generation of cover plate processing errors.
[0022] 2. The present invention provides an oil injector to spray lubricating oil on the stamping template. During the stamping process, the friction between the die and the workpiece and the plastic deformation of the workpiece will cause a large amount of heat to be generated. The stamping template can be cooled by the lubricating oil. The oil injector is inclined toward the stamping template. The two oil injectors spray at the same time to ensure that the lubricating oil at the bottom of the stamping template is sprayed evenly. When processing the next cover plate, the lubricating oil can reduce the wear between the plate and the equipment, and at the same time reduce the heat generated by friction, so as to avoid excessive temperature that will soften the processed material and adhere to the punch head or die surface, affecting the quality of the cover plate.
[0023] 3. The present invention is provided with a hydraulic cylinder to push the stamping table. After the cover plate is processed, the hydraulic cylinder continuously pushes the stamping table to rotate and tilt upward, so that the cover plate on the top of the stamping table slides to the top of the conveyor for transmission. Since the surface temperature of the cover plate after stamping is too high, manual operation is prone to injury. The hydraulic cylinder pushes the stamping table to tilt and completes the cover plate moving and material taking operation, which effectively improves the work efficiency of the cover plate processing and avoids damage caused by high temperature.

DETAILED DESCRIPTION
[0032] The present invention provides a filter cover plate processing device and method, such as Figure 1 - Figure 7As shown, it includes a workbench 1 and an equipment frame 2 fixedly installed on the top thereof, a lower mold assembly 3 for placing a cover plate is arranged on the top of the workbench 1, a punch slider 5 is arranged in the middle of the inner cavity of the equipment frame 2, an upper mold assembly 6 for stamping is arranged at the bottom end of the punch slider 5, oil storage barrels 9 are arranged at both ends of the equipment frame 2, and an injector 10 is fixedly connected to the bottom end of the oil storage barrel 9.
[0033] Further, such as Figure 3 As shown, the lower die assembly 3 includes a fixed frame 31 fixedly connected to the top of the workbench 1, four hydraulic push rods 33 are arranged below the fixed frame 31, and the protruding ends of the hydraulic push rods 33 are fixedly connected to the first limit block 34. The height of the first limit block 34 is controlled by the hydraulic push rods 33. A stamping table 35 is arranged in the middle of the top of the fixed frame 31, and the plate required for cover plate processing is placed on the top of the stamping table 35 for stamping operation.
[0034] Further, such as Figure 4 As shown, the upper die assembly 6 includes a stamping template 61 installed at the bottom end of the punch slider 5, and four mounting grooves 62 are opened at the bottom end of the stamping template 61. The top of the inner cavity of the mounting groove 62 is fixedly connected with a spring 63, and the bottom end of the spring 63 is fixedly connected with a fixing block 64. When the stamping template 61 moves downward for stamping, before contacting the surface of the plate, the fixing block 64 first contacts the top of the plate to fix the position of the plate to avoid the position of the plate from shifting during stamping, resulting in inaccurate stamping position and cover plate processing errors. The bottom end of the stamping template 61 is fixedly connected with four second limit blocks 65.
[0035] Further, such as Figure 5 As shown, four ejection grooves 32 are opened at the top of the fixing frame 31, and the four ejection grooves 32 and the hydraulic ejector rods 33 are arranged in a rectangular array. The position of the first limit block 34 corresponds to the position of the ejection groove 32, and the first limit block 34 is movably connected to the inner cavity of the ejection groove 32. The ejection groove 32 ensures the stability of the first limit block 34 when it moves.
[0036] Further, such as Figure 5As shown, two baffles 66 are fixedly connected to the bottom end of the stamping template 61. After the plate is fixed, the stamping template 61 continues to descend. As the stamping template 61 is pressed downward, the fixing block 64 is compressed into the inner cavity of the mounting groove 62 by the spring 63, so that the plate is fixed between the two baffles 66 to ensure that the position of the plate will not shift during stamping. The position of the stamping template 61 corresponds to the position of the stamping platform 35. The stamping template 61 is located above the stamping platform 35. Four second limit blocks 65 are arranged in a rectangular array. The position of the second limit block 65 corresponds to the position of the first limit block 34. When the second limit block 65 descends to the top of the first limit block 34, the punch slider 5 stops descending, and the plate is stamped through the stamping template 61 to complete the processing of the cover plate. During the stamping process, the stamping depth is controlled by the first limit block 34 and the second limit block 65 to ensure the accuracy of the cover plate size and avoid deformation of the cover plate or incomplete stamping.
[0037] Further, such as Figure 6 and Figure 7 As shown, a first rotating connection block 37 is fixedly connected to one side of the bottom end of the inner cavity of the fixed frame 31, a groove is provided at the top of the fixed frame 31, one end of the punching table 35 is rotatably connected to one side of the inner cavity of the groove, a hydraulic cylinder 36 is arranged below the punching table 35, and a second rotating connection block 38 is fixedly connected to one side of the bottom end of the punching table 35, the bottom end of the hydraulic cylinder 36 is rotatably connected to the first rotating connection block 37, and the extended end of the hydraulic cylinder 36 is rotatably connected to the second rotating connection block 38. When the extended end of the hydraulic cylinder 36 is extended, it continuously pushes the punching table 35 to rotate and tilt upward, and the punching table 35 rotates between the second rotating connection block 38 and the extended end of the hydraulic cylinder 36, and the hydraulic cylinder 36 also rotates through the first rotating connection block 37, so that one end of the punching table 35 rotates in the groove of the fixed frame 31, and when the extended end of the hydraulic cylinder 36 is extended to the longest, the punching table 35 tilts, and the cover plate at the top will slide off, completing the material removal, effectively improving the work efficiency of the cover plate processing, and avoiding high temperature damage.
[0038] Further, such as Figure 1 and Figure 2 As shown, a braking device 4 is provided at the top of the inner cavity of the equipment frame 2, and a punch rod 7 is fixedly connected to the output end of the braking device 4. The bottom end of the punch rod 7 passes through the punch slider 5 and is fixedly connected to the top of the stamping template 61. The driving force is provided by the braking device 4, so that the punch slider 5 can drive the stamping template 61 to complete the stamping operation.
[0039] Further, such as Figure 1As shown, guide rails 8 are provided on both sides of the inner cavity of the equipment frame 2, and slide grooves are opened on both sides of the punch slider 5. The punch slider 5 is movably connected to the guide rails 8 through the slide grooves, and the two ends of the stamping template 61 are movably connected to the outer surfaces of the two guide rails 8 respectively. The guide rails 8 ensure the stability of the punch slider 5 and the stamping template 61 during the up and down movement.
[0040] Further, such as Figure 1 and Figure 5 As shown, one end of the injector 10 away from the oil storage barrel 9 is inclined toward the stamping template 61, and the injectors 10 on both sides spray upward at the same time to ensure that the lubricating oil at the bottom of the stamping template 61 can be sprayed evenly. During the stamping process, the friction between the mold and the workpiece and the plastic deformation of the workpiece will cause a large amount of heat to be generated. The stamping template 61 can be cooled by the lubricating oil. When processing the next cover plate, the lubricating oil can reduce the wear between the plate and the equipment, and at the same time reduce the heat generated by friction, so as to avoid excessive temperature that will soften the processed material and adhere to the punch head or mold surface, affecting the quality of the cover plate.
[0041] Further, such as Figure 1 As shown, a support frame 11 is fixedly installed at one end of the workbench 1, and a conveyor 12 is arranged in the middle of the support frame 11. When the stamping table 35 is tilted, the formed cover plate automatically slides to the top of the conveyor 12 for transmission, which effectively improves the work efficiency of the cover plate processing and avoids damage caused by high temperature.
[0042] The present invention also provides a method for processing filter cover plate equipment, comprising the following steps:
[0043] Step 1: According to the thickness of the plate, the height of the first limit block 34 is adjusted by the hydraulic push rod 33, so that the height of the first limit block 34 and the second limit block 65 is the same as the thickness of the cover plate. After the adjustment is completed, the brake device 4 is started, and the brake device 4 drives the punch slider 5 to slide downward on the surface of the guide rail 8, driving the stamping template 61 to move downward. Before the second limit block 65 descends to the top of the first limit block 34, the fixed block 64 first contacts the top of the plate to fix the position of the plate, so as to avoid the position of the plate being offset during stamping, resulting in inaccurate stamping position and the generation of cover plate processing errors;
[0044] Step 2: After the sheet is fixed, the stamping template 61 continues to descend, and the fixing block 64 is compressed into the inner cavity of the mounting groove 62 by the spring 63 as the stamping template 61 is pressed downward, so that the sheet is fixed between the two stop bars 66, ensuring that the position of the sheet does not change during the stamping process. When the second limit block 65 descends to the top of the first limit block 34, the punch slider 5 stops descending, and the sheet is stamped by the stamping template 61 to complete the processing of the cover plate. During the stamping process, the stamping depth is controlled by the first limit block 34 and the second limit block 65 to ensure the accuracy of the cover plate size and avoid deformation of the cover plate or incomplete stamping.
[0045] Step 3: After the stamping is completed, the brake device 4 drives the punch slider 5 back to the initial position, and then the lubricating oil in the inner cavity of the oil storage barrel 9 is sprayed on the bottom of the stamping template 61 through the injector 10. The injectors 10 on both sides spray upward at the same time to ensure that the lubricating oil at the bottom of the stamping template 61 can be sprayed evenly. During the stamping process, the friction between the mold and the workpiece and the plastic deformation of the workpiece will cause a large amount of heat to be generated. The stamping template 61 is cooled by the lubricating oil, and then the next cover plate processing operation is carried out. When the next cover plate is processed, the lubricating oil can reduce the wear between the plate and the equipment, and at the same time reduce the heat generated by friction, so as to avoid the softening of the processed material due to excessive temperature, and adhere to the surface of the punch head or mold, which affects the quality of the cover plate;
[0046] Step 4: After the cover plate processing is completed, start the hydraulic cylinder 36. When the protruding end of the hydraulic cylinder 36 is extended, it continuously pushes the punching table 35 to rotate and tilt upward. The punching table 35 rotates between the protruding end of the hydraulic cylinder 36 through the second rotating connecting block 38, and the hydraulic cylinder 36 also rotates through the first rotating connecting block 37, so that one end of the punching table 35 rotates in the groove of the fixed frame 31. When the protruding end of the hydraulic cylinder 36 is extended to the longest, the punching table 35 tilts, and the cover plate at the top will slide to the top of the conveyor 12 and be conveyed to the next process. Since the surface temperature of the cover plate after stamping is too high, manual operation is prone to injury. The hydraulic cylinder 36 pushes the punching table 35 to tilt, and the cover plate moving and material taking operation is completed, which effectively improves the work efficiency of the cover plate processing and avoids damage from high temperature.
