Description

Technical Field

[0001] The invention belongs to the technical field of tap processing equipment and relates to an intelligent manufacturing production line for taps. Background Art

[0002] As a commonly used thread processing tool, tap products have a domestic market sales scale of about 4 billion yuan per year, and a global market scale of about 10 billion yuan per year. At present, about 80% of domestic tap production is labor-intensive single-machine single-process batch production, with an annual per capita output value of about 150,000 to 200,000 yuan, low labor productivity, and low product added value.

[0003] The production process of taps includes turning blanks, grinding center holes, grinding square tails, grinding centers, grinding grooves, grinding outer circles, and grinding threads. The existing method of producing taps is to produce them individually through independent machine tools. For example, Chinese patent application CN105196117A discloses a fully automatic CNC tap thread grinder, which is used for high-precision fully automatic relief grinding of taps to complete thread grinding; Chinese utility model patent CN207564219U discloses a CNC tap grinder that can realize operations such as screw tips, straight grooves, rotating grooves, chamfers, relief pins, and neck grinding of taps. The disadvantage is that the operations that can be performed by a single machine tool are limited after all, and it is impossible to form an automated production line, which affects labor efficiency and the labor cost is too high.

[0004] In order to achieve full automation of tap production, technicians have made many attempts to automate various links. For example, Chinese utility model patent CN207564309U discloses a tap loading and unloading system, which realizes the automation of tap loading and unloading. These attempts have improved the automation level of tap production, but there is still a long way to go before full automation of tap production. Summary of the invention
