Description

Technical Field

[0001] The utility model relates to the technical field of production equipment, in particular to a steel ring indentation machine. Background Art

[0002] A steel socket concrete jacking pipe refers to a pipe with high strength and long service life. One end of a cement pipe is pre-buried with a steel ring. Half of the steel ring is buried in the concrete, and the other half forms a socket. The other end of the cement pipe is made into a spigot that matches the steel ring. During installation, the steel ring is used as the socket and spigot connection. However, the current steel ring is produced by rolling with a rolling machine and then welding, with poor strength. During the production of various pipe-making equipment, it is prone to deformation (becoming flattened), affecting the later assembly and waterproofing of the product, resulting in a low product qualification rate. Content of the Utility Model

[0004] To achieve the above purpose, the technical solution adopted by the steel ring indentation machine of the utility model is as follows:

[0005] A steel ring indentation machine includes a frame. A fixed seat is arranged on one side of the frame. A first rolling wheel is pivotally connected to the fixed seat. A plurality of depressions or protrusions are arranged on the outer peripheral surface of the first rolling wheel. The fixed seat is provided with a first driving mechanism for driving the first rolling wheel to rotate. The frame is connected with a sliding seat through a first reciprocating mechanism. A second rolling wheel is pivotally connected to the sliding seat. The sliding seat is provided with a second driving mechanism for driving the second rolling wheel to rotate. A plurality of protrusions or depressions are arranged on the outer peripheral surface of the second rolling wheel. The protrusions and depressions are in one-to-one correspondence and cooperate to roll and form indentations on the surface of the steel ring. Place the steel ring between the first and second rolling wheels. Drive the sliding seat through the first reciprocating mechanism so that the steel ring can contact the first and second rolling wheels simultaneously. Start the first and second driving mechanisms. The first and second rolling wheels rotate in opposite directions. At the same time, drive the sliding seat to feed forward by the thickness of the steel ring material through the first reciprocating mechanism. During the rotation of the steel ring with the first and second rolling wheels, the protrusions and depressions cooperate in one-to-one correspondence and gradually roll and form indentations on the surface of the steel ring.

[0006] Preferably, at least two first vertical rollers are movably connected to the frame. The first vertical rollers are adjacent to the first rolling wheel and the second rolling wheel at the same time. The frame is provided with a second reciprocating mechanism for driving the first vertical rollers to fit or move away from the steel ring.

Detailed Embodiments

[0023] The following further clarifies the present utility model in conjunction with the drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. After reading the present utility model, various equivalent forms of modification by those skilled in the art all fall within the scope defined by the appended claims of this application.

[0024] Such as Figures 1 to 5As shown in the figure, a steel ring indentation machine includes a frame 1. A fixed seat 2 is arranged on the front side of the frame. The fixed seat includes an upper fixed mounting plate 21 and a lower fixed mounting plate 22 fixedly connected to the frame. A first rolling wheel 3 is pivotally connected between the upper and lower fixed mounting plates. A plurality of depressions 31 are formed on the outer peripheral surface of the first rolling wheel. A first driving mechanism 221 for driving the first rolling wheel to rotate is installed at the bottom of the lower fixed mounting plate. The frame is connected to a sliding seat 4 through a first reciprocating mechanism 11. The sliding seat includes an upper sliding mounting plate 41 and a lower sliding mounting plate 42 slidably connected to the frame. The first reciprocating mechanism is two parallel first hydraulic cylinders. The cylinder body of the first hydraulic cylinder is fixedly connected to the frame. The telescopic rod of the upper first hydraulic cylinder is fixedly connected to the upper sliding mounting plate, and the telescopic rod of the lower first hydraulic cylinder is fixedly connected to the lower sliding mounting plate. Guide grooves 12 are formed on both sides of the frame corresponding to the upper and lower sliding mounting plates. A second rolling wheel 5 is pivotally connected between the upper and lower sliding mounting plates. A second driving mechanism 421 for driving the second rolling wheel to rotate is installed at the bottom of the lower sliding mounting plate. Both the first and second driving mechanisms are hydraulic motors, and the hydraulic motors can provide a large torque. A plurality of protrusions 51 are integrally formed on the outer peripheral surface of the second rolling wheel. The protrusions and depressions cooperate one by one to roll and form indentations on the surface of the steel ring. A first limiting plate 32 is installed at the top of the first rolling wheel. An annular support platform 52 is integrally formed at the bottom of the second rolling wheel. The annular support platform is used to support the steel ring and cooperate with the first limiting plate to limit the up and down movement of the steel ring during the indentation process. A pressing plate 6 is arranged above the fixed seat. The pressing plate is hinged to the top of the frame. The frame installs a third reciprocating mechanism 13 for driving the pressing plate to press the fixed seat tightly. The third reciprocating mechanism is a third hydraulic cylinder, which can provide a large and stable pressure. In order to leave a passage space for the steel ring, the upper part of the fixed seat needs to be designed as a cantilever structure, and its strength is poor. When the steel ring is squeezed, it will move up and down. When moving downward, it is blocked by the annular convex platform. The two sides of the lower sliding mounting plate are stuck in the guide grooves, which can provide sufficient supporting force for the annular convex platform. When moving upward, it is blocked by the first limiting plate. At this time, the third hydraulic cylinder is required to drive the pressing plate to tightly press the upper fixed mounting plate to enhance the strength of the upper fixed mounting plate. The frame is movably connected with two first vertical rollers 7. The first vertical rollers are adjacent to the first rolling wheel and the second rolling wheel at the same time. The two first vertical rollers are symmetrically located on both sides of the first and second rolling wheels. The frame installs a second reciprocating mechanism 8 for driving the first vertical rollers to fit or move away from the steel ring. The two first vertical rollers are simultaneously in contact with the steel ring through the second reciprocating mechanism to prevent the steel ring from running off during the extrusion process. The second reciprocating mechanism includes a second hydraulic cylinder 81. The cylinder body of the second hydraulic cylinder is hinged to the frame. The telescopic rod of the second hydraulic cylinder is connected to the roller shaft of the first vertical roller through a first connecting rod 82. The roller shaft of the first vertical roller is connected to a rotating body 84 pivotally connected to the frame through a second connecting rod 83. The rotating body is a roller. The outer sleeve of the roller is connected to the roller shaft of the first vertical roller through the second connecting rod. The frame is movably connected with two second vertical rollers 9. The second vertical rollers are located on the opposite side of the first vertical rollers. A second limiting plate 91 is installed on the upper side of the outer sleeve of the second vertical roller. An annular supporting plate 92 is installed on the lower side of the outer sleeve of the second vertical roller. The annular supporting plate and the annular convex platform cooperate to jointly support the steel ring.Meanwhile, with the displacement of the second vertical roller, it can be applicable to steel ring indentations of different diameters. The top end of the roller shaft of the second vertical roller is fixedly connected with a handle 93, and the bottom end of the roller shaft of the second vertical roller is threadedly connected with a locking block 94. The frame is provided with a T-shaped groove 14 for the sliding of the locking block. By rotating the roller shaft of the second vertical roller with the handle, the locking block is driven to move upward, and the locking block tightly presses the top wall of the T-shaped groove to lock the second vertical roller. Walking wheels 941 that roll in the T-shaped groove are installed on both sides of the locking block, and the walking wheels facilitate the movement of the second vertical roller along the T-shaped groove in the unlocked state.

[0025] The specific working process and principle of the present utility model: The hoisted steel ring is sleeved outside the first rolling wheel, and the second vertical roller is moved so that the annular supporting plate and the annular convex platform can jointly support the steel ring. On the basis of ensuring that the steel ring has sufficient sliding space on the annular supporting plate, the second vertical roller is locked by the handle, the third reciprocating mechanism is started to drive the pressing plate to press the upper fixed mounting plate, and then the first reciprocating mechanism is started to drive the second rolling wheel to drive the steel ring to move towards the first rolling wheel. When the steel ring simultaneously abuts against the first and second rolling wheels, the first reciprocating mechanism is paused, the second reciprocating mechanism is started to drive the two first vertical rollers to simultaneously fit with the steel ring, two hydraulic motors are started, and the rotation directions of the two hydraulic motors are opposite, so as to drive the rotation directions of the first and second rolling wheels to be opposite. Then the first reciprocating mechanism is started to drive the second rolling wheel to continuously feed towards the first rolling wheel, and the feed amount is the material thickness of the steel ring. At the same time, the second reciprocating mechanism drives the first vertical rollers to always fit with the steel ring to prevent the steel ring from running off during the indentation process, and the protrusions and depressions are correspondingly matched one by one to gradually roll and form indentations on the surface of the steel ring.
