Abstract
A self-resetting device for a steel ring expansion machine relates to the structural technology of the steel ring expansion machine for producing steel cylinder concrete pipe bell and spigot steel rings. The horizontal slide rails are uniformly distributed on the platform in the radial direction, the slide rails are respectively provided with a slide block, an oil cylinder perpendicular to the plane of the platform is arranged below the platform, a telescopic rod of the oil cylinder is fixedly connected with a cone, the cone is coaxial with the platform, the end part of the telescopic rod of the oil cylinder is far away from the radial direction of the cone, which is larger than the radial direction of the end part of the telescopic rod, and the cone is arranged on the inner side of each slide block. The utility model discloses complete machine simple structure, convenient operation, control is accurate, can realize the adjustment demand of quick breathing.
Description
Technical field
The utility model relates to a kind of production equipment, especially for the structure technology of the steel loop round-expanding machine of producing cylinder concrete pipe bell and spigot steel loop.
Background technology
At present, it is round that in the technological process of domestic production cylinder concrete pipe, it holds, socket steel ring adopts round-expanding machine to expand, and the bloated piece on the round-expanding machine must be able to tighten, and piece takes out with the back of having expanded diameter reduction so that easy and convenient the packing into of bell and spigot steel loop expanded.The general bloated block reset of drawback cylinder jacking that adopts, not only speed is slow but also mechanism is complicated.
The utility model content
The utility model provides a kind of mechanism simple at above problem, and can realize the quick-adjustsing automatic runback device that is used for the steel loop round-expanding machine.
The utility model comprises platform, radial equipartition horizontal slide rail on platform, slide block is set respectively on each slide rail, the oil cylinder vertical with platform plane is set below platform, the fixedly connected cone of the expansion link of described oil cylinder, described cone is coaxial with described platform, and to greater than near the expansion link end radially, described cone is arranged in the inboard of each slide block away from the described pyramidal tract of oil cylinder expansion link end.
During its expansion link withdrawal of oil cylinder work, drive cone and move downward, each slide block that is positioned at the cone outside moves laterally along corresponding slide rail, diameter is swollen, when oil cylinder reset strap mantle body rose, each slide block inwardly was that the center of platform is gathered, and the slide block external diameter rises with cone and dwindles.The utility model has adapted to the job requirement of all kinds of round-expanding machines, swelling and dwindling all of the diameter that each slide block forms drives cone control by oil cylinder, the round-expanding machine cone driven realize automatically reseting of slide block when slide block is resetted by oil cylinder reset strap mantle body behind the round steel ring that expands.The utility model complete machine structure is simple, and is easy to operate, and precise control can realize the adjustment demand of quick breathing.
More accurate for cone is cooperated with each slide block, the lateral surface of cone described in the utility model is along the uniform dovetail groove of its length direction, and the medial surface of described each slide block is provided with the swallow-tail form boss of cooperation respectively.
In addition, the cross section of cone described in the utility model is a dodecagon, and the horizontal slide rail on the described platform is 12 roads.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the 1st, the cross section is the cone of dodecagon, the 2nd, slide block, the 3rd, platform, the 4th, oil cylinder.
Radial equipartition divergence form 12 road horizontal slide rail 3-1 are provided with slide block 2 respectively on each slide rail 3-1 on platform 3.The oil cylinder 4 vertical with platform 3 planes is set below platform 3, the fixedly connected cone 1 of the expansion link of oil cylinder 4, cone 1 is coaxial with platform 3, away from the cone 1 of oil cylinder 4 expansion link ends radially greater than radially near the expansion link end, the lateral surface of cone 1 is along the uniform 12 road dovetail groove 1-1 of its length direction, cone 1 is arranged in the inboard of each slide block 2, the medial surface of each slide block 2 is provided with the swallow-tail form boss 2-1 of cooperation respectively, and the swallow-tail form boss 2-1 of slide block 2 is slided in the dovetail groove 1-1 of cone 1.
Claims (3)
1, a kind of automatic runback device that is used for the steel loop round-expanding machine, comprise platform, radial equipartition horizontal slide rail on platform, slide block is set respectively on each slide rail, it is characterized in that below platform, being provided with the oil cylinder vertical with platform plane, the fixedly connected cone of the expansion link of described oil cylinder, described cone is coaxial with described platform, to greater than near the expansion link end radially, described cone is arranged in the inboard of each slide block away from the described pyramidal tract of oil cylinder expansion link end.
2, according to the described automatic runback device that is used for the steel loop round-expanding machine of claim 1, the lateral surface that it is characterized in that described cone is along the uniform dovetail groove of its length direction, and the medial surface of described each slide block is provided with the swallow-tail form boss of cooperation respectively.
3, according to the described automatic runback device that is used for the steel loop round-expanding machine of claim 2, the cross section that it is characterized in that described cone is a dodecagon, and the horizontal slide rail on the described platform is 12 roads.
