Description
Technical Field
The utility model relates to a mould protector especially relates to an automatic monitor control system of mould dash needle absolutely, belongs to mould protection control technical field.
Background
In the aspects of stamping, forging and fine blanking production in the modern die industry, semi-automation or full automation is realized to different degrees. The production process is gradually transformed from an early personnel-intensive industrial mode to an unmanned factory automatic production mode; the method is changed from a simple and crude single engineering mould to a high-precision progressive die, even a large-scale progressive die and a multi-station manipulator conveying die; the visual tracking operation of production operators is upgraded to the optical-mechanical-electrical integrated automatic monitoring control technology. Therefore, in the technical field of automatic monitoring and control, more severe requirements and challenges are provided for various technical links of mold design, processing, manufacturing and even industrial automatic production upgrading.
In response to the requirement of high-speed automatic production of die stamping, general die practitioners can design and install numerous opto-mechatronic induction monitoring control systems on the die, such as common continuous die misdelivery monitoring devices, common bottom dead center detection devices in the electronic die industry, automatic discharge photoelectric induction devices of multi-station manipulator conveying dies and continuous dies, and other peripheral accessory equipment of the press machine, so as to automatically monitor the real-time working states of the press machine and the die, ensure the stable and reliable operation of the automatic production link, expect to timely feed monitoring signals back to a PLC control system of the machine tool to respond in time and realize quick stop when abnormal working conditions occur to the press machine or the die, and simultaneously send out acousto-optic alarm signals to remind the equipment operators and the die personnel to timely overhaul, thereby avoiding the defects of large-batch products, scrapping of production, die cracking, and the like, The major accidents such as mold explosion, equipment damage, personnel disability and the like occur, and the economic loss is reduced to the minimum.
However, for automatic production systems in the stamping, forging and fine stamping industries, particularly for high-speed automatic industrial enterprises such as thick material punching dies, progressive dies, high-strength steel product punching dies, multi-station conveying dies and the like, the problem of broken punching pins is easy to occur in thick material punching, and for small holes in thick materials, the punching pins are broken and fractured sometimes under the conditions that the punching pins are weak in strength and the tensile strength, the compressive strength and the impact and shear strength of a processed plate are all very high. Meanwhile, in the small hole punching processes of a drawing die, a shaping die and a trimming and punching die of an automobile covering part which is unevenly stressed or generates complex strains such as lateral tensile stress, compressive stress and the like, the punching needle is more prone to generate frequent stress fracture or snap due to complex and variable stress working conditions. And the breakage of the impact needle under the above conditions has quite large randomness and sporadic property, which impact needles can be broken at what time period and under what working condition cannot be pre-judged in advance, and even unpredictable breakage occurs in the normal design life of the impact needle. Because the broken punching needle of the die is not found by production line personnel in time in production, the falling punching needle directly causes the occurrence of template cracking and even die explosion, and the cost for die maintenance or remaking is huge. Meanwhile, hundreds of punching parts of the semi-finished products are not found to have poor hole punching and are informed when the semi-finished products flow to the production line assembly of the customer production line of the downstream host factory, and then a large amount of manpower and material resources are spent for batch reworking. The problems cause extremely heavy economic loss and delayed order delivery loss for stamping production enterprises and general assembly client host machines, and more serious, some semi-finished products are directly scrapped due to incapability of repair.
At present, for the above problems, the existing solutions are: firstly, a mould maintenance worker maintains the mould regularly, the punching needle which is possible to have potential fracture hidden danger is replaced in advance, and the punching needle is replaced in a whole batch in advance when the design life of the punching needle is not reached, so that a lot of punching needle consumables are scrapped prematurely in advance, the due value of the punching needle consumables can not be fully utilized, serious waste is generated, and even if the situation is that the situation and the working condition of the replaced new punching needle can not be ensured to have unpredictable fracture; and secondly, after the die punching needle is broken and discovered by a production line inspection worker, the whole automatic production line is manually controlled to stop, a die maintenance worker is arranged to disassemble the die for maintenance and replace the broken punching needle, a damaged template and the like, and the discarded product-in-process stamping part which is discarded due to missing punching or damaged die is selected, so that the facts that the batch of the product-in-process stamping part is poor, the scrap is discarded, the die is damaged and the press is damaged are caused, irreversible damage is possibly caused to the hardware of the press equipment, and the production cost loss is great.
