Description

Technical Field

[0001] This utility model relates to the field of punch and die production technology, and in particular to an adjustable grinding mechanism for high-precision punch and die production. Background Technology

[0002] High-precision punches and dies are core components in the mold industry, playing a decisive role in product molding. They have extremely stringent dimensional tolerance requirements, with micron-level error control being very common, ensuring that parts produced by stamping, injection molding, and other molding processes are dimensionally accurate and have a high degree of fit.

[0003] High-precision punches and dies are made from a diverse and sophisticated range of materials, including various high-performance alloy steels and cemented carbides. Depending on the working conditions, they possess excellent wear resistance, compressive strength, and thermal stability. Their shapes are complex and varied, ranging from simple geometric contours to three-dimensional irregular structures, adapting to the complex appearance requirements of electronic products, automotive parts, and aerospace precision components. Extremely high surface finishes are required to reduce demolding resistance and prevent scratches and damage to the products. The manufacture of these punches and dies relies on cutting-edge processing technology, specialized equipment, and highly skilled technicians, making them an indispensable key element for achieving high-quality, refined production goals in high-end manufacturing.

[0004] However, traditional grinding mechanisms generate a large amount of debris and dust during use, affecting the cleanliness of the working environment for workers. At the same time, workers inhale a large amount of debris and dust, which can easily harm their health. Furthermore, it is inconvenient to clean up the collected dust and debris, making it difficult for workers to clean up and reducing their work efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable grinding mechanism for high-precision punch and die production, aiming to improve the problems of existing grinding mechanisms that generate a large amount of debris and dust during use, which not only affects the cleanliness of the working environment, but also easily harms the health of workers, and is difficult to clean, thus reducing work efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable grinding mechanism for high-precision punch and die production, comprising a mounting plate, a support plate fixedly connected to the outside of the mounting plate, a top plate fixedly connected to the side of the top support plate away from the mounting plate, a bottom plate fixedly connected to the outside of the bottom support plate, a transmission mechanism provided on the top of the mounting plate, and a cleaning mechanism fixedly connected to the top of the bottom plate.

[0007] The transmission mechanism includes a hydraulic cylinder, with a slider 1 fixedly connected to the output end of the hydraulic cylinder. An assembly platform is fixedly connected to the top of the slider 1. An installation slot is provided inside the assembly platform. An installation frame is fixedly connected inside the installation slot. An electric push rod 2 is fixedly connected inside the installation frame. A moving block is fixedly connected to the output end of the electric push rod 2. The moving block is slidably connected inside the installation frame. Limiting components are provided on the outside of the moving block.

[0008] Furthermore, the limiting assembly includes two connecting rods, both of which are rotatably connected to the outside of the moving block. The end of the connecting rod away from the moving block is rotatably connected to the outside of the second slider, and a clamping plate is fixedly connected to the top of the second slider.

[0009] Furthermore, the cleaning mechanism includes a collection box, the bottom of which is fixedly connected to the top of the base plate, an air pump fixedly connected to the top of the collection box, an air extraction pipe fixedly connected to the output end of the air pump, an air filter fixedly connected inside the collection box, the bottom end of the air extraction pipe being located inside the air filter, a delivery pipe fixedly connected inside the collection box, and a flushing assembly fixedly connected to the top of the collection box.

[0010] Furthermore, the flushing assembly includes an exhaust pump, which is fixedly connected to the top of the collection box. A connecting pipe is fixedly connected to the outside of the exhaust pump, and an air outlet pipe is fixedly connected to the other end of the connecting pipe. The air outlet pipe is fixedly connected to the inside of the collection box, and air nozzles are fixedly connected to the outside of the air outlet pipe.

[0011] Furthermore, a dust collection hood is fixedly connected to the other end of each of the conveying pipes, and the bottom of the dust collection hood is fixedly connected to the top of the mounting plate.

[0012] Furthermore, an electric push rod is fixedly connected to the bottom of the top plate, a fixed plate is fixedly connected to the output end of the electric push rod, a motor is fixedly connected to the top of the fixed plate, and a grinding disc is fixedly connected to the output end of the motor.

[0013] Furthermore, a groove is provided on the top of the mounting plate, and a slider is slidably connected inside the groove.

[0014] Furthermore, each assembly platform has a limiting groove on its top, and each limiting groove has a slider connected to it.

[0015] This utility model has the following beneficial effects:

[0016] In this utility model, when it is necessary to limit and fix the product, the electric push rod 2 is driven to move the moving block. While the moving block moves, it drives the connecting rods on both sides to move. While the connecting rods move, it drives the slider 2 to move. The slider 2 is limited by the limiting groove, so it moves relative to each other. While the slider 2 moves, it drives the clamping plates to move closer or further away from each other. The clamping plates move closer to each other to limit and fix the product to be polished, thereby realizing the adjustment and clamping fixation of the product to be polished.

[0017] In this invention, when it is necessary to clean the dust generated during grinding, an air pump is driven, and then the dust generated during grinding is extracted through the delivery pipe and the collection hood. The air pump extracts the gas inside the air filter element, making the inside of the air filter element a negative pressure state. The air inside the collection box enters the air filter element, and the dust inside the collection box is adsorbed on the outside of the air filter element, so that no time is spent cleaning it again later.

[0029] Reference Figure 1 , Figure 2 and Figure 5The cleaning mechanism includes a collection box 22, the bottom of which is fixedly connected to the top of the base plate 2. An air pump 24 is fixedly connected to the top of the collection box 22, and an air extraction pipe 26 is fixedly connected to the output end of the air pump 24. An air filter 25 is fixedly connected inside the collection box 22, and the bottom end of the air extraction pipe 26 is located inside the air filter 25. A delivery pipe 23 is fixedly connected to the inside of the collection box 22. A flushing assembly is fixedly connected to the top of the collection box 22, and the flushing assembly includes an exhaust pump 27. The exhaust pump 27 is fixedly connected to... The exhaust pump 27 is fixedly connected to the top of the collection box 22 by a connecting pipe 28. The other end of the connecting pipe 28 is fixedly connected to an air outlet pipe 29. The air outlet pipe 29 is fixedly connected to the inside of the collection box 22. Air nozzles 30 are fixedly connected to the outside of the air outlet pipe 29.

[0033] Working Principle: During operation, the electric push rod 15 drives the moving block 16 to move. Simultaneously, the moving block 16 moves the connecting rods 17 on both sides. The connecting rods 17, through the limiting groove 21, drive the slider 18. Simultaneously, the slider 18 moves the clamping plates 19, which limit and fix the product to be polished, thus achieving adjustment and clamping. When polishing begins, the electric push rod 8 drives the fixing plate 9 and motor 10 to move up and down. The motor 10 drives the polishing disc 11 to polish the convex and concave molds. Simultaneously, the air pump 24 operates synchronously, drawing air from the air filter 25 to create a negative pressure environment. Under the pressure difference, air from the collection box 22 flows into the air filter 25. Through the delivery pipe 23 and the dust suction hood 20, dust generated during polishing is continuously drawn into the collection box 22 and adheres to the outside of the air filter 25.

[0034] After the grinding and dust collection processes have continued for a period of time, the exhaust pump 27 of the flushing component is started, compresses the air and discharges it into the air outlet pipe 29, and finally sprays it out at high speed from the air nozzle 30. With the impact of the strong airflow, the dust accumulated on the outside of the air filter element 25 is washed off, realizing backflushing dust removal, maintaining the good dust collection and purification effect of the equipment, and ensuring a clean working environment.
