DETAILED DESCRIPTION
[0011] A troubleshooting mechanism for a crossbeam assembly of a press machine, the troubleshooting mechanism comprising a crossbeam 1, a tie rod nut 2, a locking tie rod 3, a guide sleeve 1 4, a base 5, an upper gland 6 of a cylinder, a cylinder 7, a lower gland 8 of a cylinder, a tie rod piston 9, a guide sleeve 2 10, a guide post 11, a guide sleeve gland 12, and a slide block 13; The crossbeam 1 and the base 5 are connected as one body through a locking rod 3, and a rod nut 2 is arranged on the upper part of the locking rod 3, and a rod piston 9 is arranged on the lower part; A guide sleeve 4 is provided between the cross beam 1 and the base 5, and the tie rod nut 2 is rigidly connected to the cross beam 1 through screws. When the locking tie rod 3 moves, the cross beam 1 moves along with it; The tie rod piston 9 is arranged in the oil cylinder 7, and the upper and lower ends of the oil cylinder 7 are respectively provided with an oil cylinder upper pressure cover 6 and an oil cylinder lower pressure cover 8. The oil cylinder upper pressure cover 6 is provided with a cross beam fall high pressure oil port 61, and forms a cross beam fall high pressure oil chamber with the upper part of the tie rod piston 9; the oil cylinder lower pressure cover 8 is provided with a cross beam top rise high pressure oil port 81, and forms a cross beam top rise high pressure oil chamber with the lower part of the tie rod piston 9, and the K value is the stroke of the cross beam top rise or fall; The slider 13 is rigidly connected to the crossbeam 1; The guide column 11 is rigidly connected to the slider 13; The second guide sleeve 10 is disposed in the base 5 , and the guide post 11 can perform up and down reciprocating motion in the second guide sleeve 10 .
[0012] An upper mold is installed on the slider 13 , and a lower mold is installed on the base 5 .
[0013] A guide sleeve pressure cover 12 is provided on the upper portion of the guide sleeve 10 to fasten it in the base 5 , thereby preventing the guide sleeve 10 from being thrown out of the base 5 during the movement of the guide post 11 .
[0014] The working principle of the present invention is: When the press is in normal use, the crossbeam of the lower cover 8 of the cylinder pushes up the high-pressure oil port 81 and is disconnected from the high-pressure oil pump, and the crossbeam of the upper cover 6 of the cylinder falls back to the high-pressure oil port 61 and is connected to the high-pressure oil pump. When the crossbeam falls back, the high-pressure oil cavity is filled with high-pressure oil. This high-pressure oil can stretch the locking rod 3 and eliminate the matching clearance between the upper and lower end threads of the locking rod 3 and the threads of the rod nut 2 and the rod piston 9, so that the crossbeam 1 and the base 5 are pre-tightened together, which also improves the rigidity of the press and the performance of the press.
[0015] When the mold fails, the crossbeam of the upper cover 6 of the oil cylinder drops back to the high-pressure oil port 61 and disconnects from the high-pressure oil pump, and the oil in the high-pressure oil cavity is discharged through the oil port. At the same time, the crossbeam of the lower cover 8 of the oil cylinder pushes up the high-pressure oil port 81 and connects to the high-pressure oil pump, and the high-pressure oil cavity is quickly filled with high-pressure oil, and the tie rod piston 9 is pushed upward. Since the crossbeam 1, tie rod nut 2, locking tie rod 3, tie rod piston 9, and slider 13 are a rigid body, the crossbeam assembly and the slider 13 are quickly lifted together, and the upper and lower molds of the mold are disengaged, and the workers can check and solve the mold failure.
[0016] When the mold fault is eliminated, the crossbeam of the lower cover 8 of the oil cylinder pushes up the high-pressure oil port 81 and disconnects it from the high-pressure oil pump, and the oil in the high-pressure oil chamber is discharged through the oil port. At the same time, the crossbeam of the upper cover 6 of the oil cylinder falls back to the high-pressure oil port 61 and is connected to the high-pressure oil pump. The high-pressure oil is quickly filled in the falling high-pressure oil chamber, and the pull rod piston 9 is pushed downward, so that the crossbeam assembly and the slider 13 fall back together, the upper and lower molds of the mold are closed, and the press quickly enters normal production state.
[0017] In order to ensure the movement accuracy of the beam assembly during the entire rapid lifting and falling process, this mechanism is equipped with two guide pairs, namely, the guide pair consisting of the guide sleeve 1 4 and the locking rod 3, and the guide pair consisting of the guide sleeve 2 10 and the guide column 11. During the rapid lifting and loop process, the beam assembly moves up and down under the common limit conditions of the two guide pairs, which greatly improves the movement accuracy. The clamping state and accuracy of the upper and lower molds of the mold can be kept consistent when the beam assembly is rapidly lifted and dropped, ensuring the continuity of user production.
