Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

See Fig. 1, a kind of working method of automatic brick-making system, this fully automatic brick-making system comprises: The hydroforming machine (not shown in Fig. The automatic feeder 1-3 in the code stamping area is used to limit the steam curing vehicle 1-2 to the positioner 1-4 in the code stamping area, which is used to carry out brick stamping on the steam curing vehicle 1-2 A working robot (not shown in Fig. 1), the positioner includes: a support arm 1-5, a cylinder 1-6 for supporting or lowering the support arm; the cylinder 1-6 is used for supporting or lowering the support arm arm; the locator 1-4 is fixed on a slider 1-7, that is, the other end of the cylinder 1-6 and the bottom of the arm 1-5 are respectively connected to the left and right ends of the slider 1-7 ; The slider 1-7 is slidably matched with a guide rail body 1-8, and the left end of the guide rail body 1-8 is provided with a buffer device 1-1, which is used for buffering by the steaming car 1-8. 2 The impact force of the slider generated when hitting the positioner 1-4, that is, the right side of the support arm 1-5, and the right end surface of the buffer device 1-1 is suitable for maintaining close contact with the left end surface of the slider; The working method of the fully automatic brick making system The working method includes: the buffer device 1-1 buffers the impact force of the slider when the steam curing vehicle 1-2 hits the supported arm 1-5, so as to relieve the The pressure caused by the impact of the steam curing car 1-2 on the cylinder 1-6.

It can be seen from Fig. 1 that the length of the slider 1-7 is long enough, the upper end surface is fixed with a locator, and the left end surface of the slider 1-7 is buffered and matched with the right end surface of the buffer device 1-1.

Among them, the hydraulic forming machine, the code stomping robot, the steaming car 1-2, the automatic feeding machine 1-3, the support arm 1-5, the cylinder 1-6 for supporting or lowering the support arm and other related structures You can refer to the authorized announcement number CN 101574833 B Invention Patent: Fully Automatic Hydraulic Forming of Bricks and Intelligent Code Stamping Device, as well as attached drawings 1, 2 and 8.

Because those skilled in the art generally believe that the cylinder has a certain buffering effect, but ignore that the impact force received by the steam curing car 1-2 is not in the same direction relative to the cylinder, according to mechanical analysis, after decomposition, it can be found that, The cylinder has to withstand a force greater than the impact force of the steaming car 1-2 to withstand the support arm 1-5. Due to the high efficiency of the automatic hydraulic forming machine, the work load of the support arm 1-5 is extremely large, so it is very easy to cause damage. damage, so the present invention can effectively alleviate the impact force of the steaming car 1-2, improving the life of the cylinder.

The buffer device 1-1 is a hydraulic or pneumatic buffer.

See Fig. 2, Fig. 3 and Fig. 6, described hydraulic buffer is two-stage buffer, and this two-stage buffer comprises: first stage buffer 1, last stage buffer 2; The first-stage buffers 2 respectively include: a cylinder body 4 that is cylindrical and filled with a buffer medium, and a cylinder head 5 is sealed at the open end of the cylinder body 4, and the central through hole of the cylinder head 5 is sealed and movable. There is a piston rod 6, the right end of the piston rod 6 is provided with a piston body assembly 7 for adjusting the back and forth flow of the medium, the piston body assembly 7 is suitable for piston movement in the cylinder body 4, and is connected with the cylinder body 4 The inner wall is movable and sealed; wherein, the cylinder body 4 of the first-stage buffer 1 constitutes the piston rod 6-1 of the final-stage buffer 2; As the contact surface colliding with the slider 1-7; the side wall of the cylinder 4 of the final buffer 2 is axially provided with an electromagnet 4-1; the piston body assembly of the final buffer 2 The right end face of 7 is provided with the pressure sensor 9 that is used for detecting medium pressure, and this pressure sensor is connected with a processor module; When described slider 1-7 hits the right end face of described cylinder body, described processor module According to the medium pressure value, control a current drive module to output a current matching the medium pressure value, so that the electromagnet 4-1 generates a corresponding magnetic field to attract the slider 1-7; until the processing When the medium pressure value measured by the detector module is an equilibrium value, the current drive module is controlled to close the output current, so that the magnetic field disappears, so as to release the slider 1-7; wherein, the piston body assembly 7 of each buffer is suitable for When the piston is moving, the processor controls the piston body assembly to adjust or close the medium back-and-forth flow in the corresponding cylinder 4 according to the medium pressure detected by the pressure sensor 9, so as to adjust the movement of the piston body assembly 7 speed or buffer level.

When the buffer medium flows to the left side of the piston body assembly 7, the pressure on the buffer medium on the right side of the cylinder 4 gradually decreases until the medium pressure on the left and right sides of the piston body assembly 7 is equal, that is, When the medium pressure value is an equilibrium value (that is, the pressure value when the hydraulic pressure values on the left and right sides of the piston body assembly 4 are equal), when the piston body assembly 7 stops working, the sliders 1-7 also stop moving. Especially when the pressure sensor is used to accurately detect the right end face of the cylinder body 4 when the slider 1-7 hits, the impact force of the slider 1-7 does not need to be controlled according to the medium density in each cylinder of the two-stage buffer. The order of buffering is adjusted, and the buffering rhythm can be adjusted more reasonably according to the pressure value, which prolongs the life of the buffer.

Wherein, the processor module adopts a single-chip microcomputer or an embedded ARM module; the pressure sensor 9, for example, can adopt Johnson P499VBS-404C; the current drive module can adopt an AC current output unit, and the sliders 1-7 adopt iron sliders.
