Embodiment Construction
[0019] In order to enable examiners to further understand the purpose of the present invention, a preferred embodiment is now attached for detailed description as follows. This embodiment is only used to illustrate the technical solution of the present invention, not to limit the present invention.
[0020] The circuit diagram of the present invention is as figure 1 As shown, the air circuit diagram is as figure 2 As shown, the present invention uses two AC contactors and two time relays to control the cylinder preload solenoid valve 1 and booster cylinder solenoid valve 2 respectively, and controls the cylinder preload solenoid valve 2 through the first AC contactor KM1 and the first time relay KT1. The pressure solenoid valve 1 is turned on, so that the cylinder falls to the set position within the set time; after the cylinder drops to the set position, according to the set time, the second time relay KT2 and the second AC contactor KM2 automatically controls the solenoid ...

The invention discloses a riveting machine upper and lower mold butt joint correcting method. According to the method, two alternating current contactors and two time relays are adopted for respectively controlling an air cylinder prepressing electromagnetic valve and a pressurizing cylinder electromagnetic valve, and the connection of the air cylinder prepressing electromagnetic valve is controlled through the first alternating current contactor KM1 and the first time relay KT1 so that an air cylinder is lowered to the set position in the set time; after the air cylinder is lowered to the set position, the second time relay KT2 and the second alternating current contactor KM2 automatically control the connection of the pressurizing cylinder electromagnetic valve according to the set time so that the air cylinder stops ascending and descending, the upper and lower mold contact is maintained, and the butt joint correction is completed. According to the method disclosed by the invention, upper and lower molds can automatically contact and then realize the butt joint. Compared with the traditional method for realizing the upper and lower mold contact through manually braking two electromagnetic valves in the prior art, the method disclosed by the invention has the advantages that simplicity and convenience are realized, the operation can be carried out through simple technical knowledge, the technology dependence is low, the technical difficulty of the upper and lower mold butt joint correction is reduced, and the correction time is shortened.
Description
technical field [0001] The invention relates to the field of hardware processing equipment, in particular to a method and a correction circuit for butt joint correction of upper and lower molds of a riveting machine. Background technique [0002] With the development of electronic technology, the requirements for the number of layers and circuit density of PCB circuit boards are getting higher and higher; especially after the number of layers of PCB circuit boards increases, the operation of using rivets for positioning and then blooming and fixing with a rivet machine is very important. Important; because if the alignment of the upper and lower molds of the rivet machine is not accurate, it will lead to uneven blooming and PCB circuit board layer deviation; it will affect the quality of multi-layer laminated PCB circuit boards, and even cause defective products. Therefore, in order to ensure the production quality of the rivet machine, it is necessary to calibrate the upper...
