Description

Technical Field

[0001] The invention relates to the technical field of metal pipe compression testing, in particular to an automatic hydraulic press. Background Art

[0002] A hydraulic press is a machine used to perform compression tests on metal pipes. The two ends of the metal pipe are sealed, and then water is injected into the metal pipe to increase the pressure inside the metal pipe. The metal pipe is then observed to see if there will be cracks or leaks, thereby detecting the compression resistance of the metal pipe.

[0003] Chinese patent publication number CN 215262872 U discloses a fully automatic hydraulic pressure testing machine for pipes, including a base plate and a hydraulic press, the upper end of the base plate is fixedly connected to the same U-shaped support plate through a plurality of symmetrically arranged support columns, the outer sides of the two vertical parts of the U-shaped support plate are fixedly connected to the U-shaped fixing plate, the U-shaped fixing plate and the side wall on the opposite side of the U-shaped support plate are rotatably connected to the same rotating screw through a ball bearing, a rotating motor is fixedly provided on the outer side of the U-shaped fixing plate, the output shaft of the rotating motor passes through the side wall of the U-shaped fixing plate and is fixedly connected to one end of the rotating screw, the rod wall of the rotating screw is threadedly sleeved with a movable plate, and the side of the movable plate close to the U-shaped support plate is fixedly connected to multiple push-pull rods.

[0004] The water pressure testing machine in the above patent lifts the arc-shaped support plate through a telescopic cylinder, so that the arc-shaped support plate lifts the metal tube and moves it between the two insertion cylinders, and then the two insertion cylinders are sleeved on the two ends of the metal tube to complete the fixation of the metal tube; however, the pressure resistance test of the metal tube is a link in the manufacture of the metal tube, and the metal tubes are manufactured in batches, so a large number of metal tubes need to be pressure-tested. The above water pressure testing machine does not have a metal tube transfer device, and the metal tubes can only be placed one by one on the arc-shaped support plate by the staff. Therefore, the staff needs to constantly transfer the metal tubes, which greatly increases the workload of the staff and reduces the efficiency of the metal tube pressure resistance test work; in addition, when the above water pressure testing machine is in operation, because the staff needs to constantly transfer the metal tubes, the staff must be in close contact with the water pressure testing machine, and the operating water pressure testing machine may endanger the personal safety of the staff.

[0017] Beneficial effects:

[0018] A. In the present invention, firstly, a batch of metal tubes are placed into the transfer assembly, and the metal tubes will fall one by one to the bottom of the transfer assembly in the transfer assembly, and then the loading assembly on one side of the transfer assembly can clamp the metal tube at the bottom of the transfer assembly and move it to the inspection platform, and then the inspection platform fixes the metal tube clamped by the loading assembly and performs a pressure test. When the inspection platform performs the inspection work, the loading assembly will reset and clamp the next metal tube for standby; after the metal tube on the inspection platform is inspected, the transmission assembly can drive the metal tube to rotate slowly, which is convenient for the laser marking machine on the inspection platform to mark the metal tube, thereby completing the pressure test of the metal tube; the transfer assembly cooperates with the loading assembly to automatically move the batch of metal tubes to the inspection platform one by one, without the need for staff to manually move the metal tubes, thereby reducing the workload of the staff and improving the efficiency of the inspection work, and the automatic hydraulic press does not require staff to approach during operation, thereby avoiding the automatic hydraulic press causing harm to the personal safety of the staff;

[0019] B. In the present invention, when a batch of metal tubes are placed in the transfer assembly, the metal tubes will move along the track of the guide rods on the inner side of the two side plates. The overall track of the guide rods is downward, so that the metal tubes can move by their own gravity, and the guide rods are divided into two layers, the distance between the two layers of guide rods is slightly larger than the outer diameter of the metal tubes, so that the metal tubes can move normally without accumulation, effectively preventing the accumulation of metal tubes and causing the metal tubes to be unable to fall normally; when the metal tubes fall to the push plate, the second cylinder drives the arc block fixed to it to fit with the metal tube, and both ends of the push plate close to the metal tube are arc-shaped , so that the arc block and the push plate can cooperate to clamp the metal tube, thereby preventing the metal tube from being displaced and ensuring the stability of the metal tube; then the cylinder one drives the push plate to move, and the push plate drives the metal tube to move toward the base frame, and at the same time, the cylinder two drives the arc block to move synchronously, so that the metal tube is always moved to the base frame in a stable state. At this time, the two ends of the metal tube away from the push plate are fitted with the two positioning blocks. The cooperation of the two positioning blocks, the push plate and the arc block can ensure the stability of the metal tube on the base frame, effectively preventing the metal tube from tilting, etc., thereby ensuring that the loading assembly can clamp the metal tube normally.

[0020] When the two guide wheels are rotated, the guide wheels are driven by the motor to move along the groove of the transmission wheel, and the two guide wheels are driven by the motor to move along the groove. When the two guide wheels are moved, the guide wheels are driven by the motor to move along the groove. When the two guide wheels are moved, the guide wheels are driven by the motor to move along the groove. When the two guide wheels are moved, the guide wheels are driven by the motor to move along the groove.

[0021] D. In the present invention, after the clamping assembly clamps the metal pipe, the motor drives the lower gear to rotate, and the lower gear drives the upper gear to rotate through the chain, and the upper gear drives the clamping assembly to rotate with the rotation axis of the clamping assembly as the center. When the clamping assembly rotates, it can drive the metal pipe clamped by the clamping member to rotate and rise, allowing the clamping assembly to transport the metal pipe to the inspection platform; the support frame plays the role of supporting the motor and the clamping assembly, and at the same time enables the clamping assembly to rotate normally. In addition, the support frame is provided with a rectangular groove at one end close to the clamping assembly for the clamping assembly to pass through when rotating, so as to prevent the support frame from causing obstruction when the clamping assembly rotates;

[0022] E. In the present invention, after the metal tube is transported to the testing platform, the first stroke adjustment assembly and the second stroke adjustment assembly each drive the pressure block connected thereto to move toward the metal tube. The axial bearings and the sealing gaskets move synchronously with the pressure blocks until the two pressure blocks clamp the metal tube. The loading assembly then moves in the opposite direction to reset the clamping assembly and clamp the next metal tube. When the testing platform performs a pressure test on the metal tube, the sealing gasket seals the metal tube, preventing water in the metal tube from flowing out of the end of the metal tube, thereby ensuring the accuracy of the testing result. After the metal tube is tested, the cylinder 3 of the transmission assembly drives the slide 3 to move toward the testing platform until the rubber wheel above the slide 3 is in contact with the metal tube. The motor 3 then drives the rubber wheel to rotate, causing the rubber wheel to rotate the metal tube through friction. The laser marking machine then marks the metal tube during its rotation. As the metal tube rotates, the axial bearings on the two pressure blocks can rotate synchronously with the metal tube and can withstand the pressure generated by the pressure blocks. This allows the two pressure blocks to clamp the metal tube without affecting the normal rotation of the metal tube, ensuring that the marking work can proceed normally.
