Description
Technical field
The invention belongs to pipe expanding equipment, more particularly to a kind of pipe end expanding machine.
Background technology
With the extensive use of modernization control technology, the control accuracy and its part accuracy of plastic forming equipment with from
Before cannot be mentioned in the same breath.Using the machinery expanding technique based on module reaming principle and the machinery expanding based on modern control technology
The technology of equipment, manufacture high-quality large diameter thin wall tubular part and pipeline steel cylinder, is a kind of advanced manufacturing technology, is expected in boat
My god, non-ferrous metal and mechanical manufacturing field be applied.
International market can produce and provide the manufacturer of expanding machine and the technology of expanding head is kept absolutely secret.Expanding head due to
Take up space limited, shape is complicated with embedding structure.Expanding head stress is：The axial movement conversion of pull bar is directly contacted
The radial motion of steel pipe tube wall modules, forces steel pipe wall material matter to produce flowing and extend, steel pipe caliber becomes large-sized.Current state
Have on border to the method that the design of expanding head is generally used：By loaded on the cone on pull bar, the axial force that cone is born
The radial direction for directly contacting tube wall modules operation and radial load are converted to being axially moved.Inside pipe wall institute is acted on by the radial load
Complete pipe expanding.Due to it is earliest be hydraulic cylinder resetting means, hydraulic cylinder may not necessarily be good when expanding completion back stay stretches out
Running, cause module resets state uneven.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of pipe end expanding machine so that expand
Footpath equipment can make equipment equably be reset to expanding preceding location status after to the expanding completion of pipe end.
Technical scheme：To achieve the above object, a kind of pipe end expanding machine of the invention, including cone, voussoir, T-shaped block,
Support plate, disk spring and pull bar；Described pull bar sequentially passes through locking nut, nut, oil distribution casing, cone and support plate, institute
The locking nut stated is fixedly connected with nut, and nut is fixedly connected with oil distribution casing, and oil distribution casing is fixedly connected with cone, described lock
Tight nut, nut, oil distribution casing, cone and support plate are fixedly connected with pull bar respectively.Described voussoir is enclosed on by being slidably connected
In cone, the periphery of described voussoir is cased with cushion block, and the periphery of described cushion block is cased with secter pat.Described voussoir, cushion block and
The circular arc end face that secter pat is constituted is fixedly connected with the circular arc end face that T-shaped block is constituted, the circular arc end face that T-shaped block is constituted
Another side is fixedly connected with support plate.
Described support plate and the periphery of T-shaped block are mounted with butterfly spring.
Further, voussoir is connected with cushion block by round key, and described cushion block is connected with secter pat by round key.
Further, anticollison block is installed on secter pat.
Beneficial effect：The present invention in the periphery of described support plate and T-shaped block by being mounted with butterfly spring so that
Expanding machine is after the completion of expanding, and T-shaped block and other parts result in the restoring force that butterfly spring is provided so that set
It is standby uniformly to reset to original state；Anticollison block is installed on described secter pat, T-shaped block can be effectively protected, in order to avoid steel pipe
The impulsive force of end face causes to damage to T-shaped block.The present invention, as expanding machine resetting means, can make to set by using butterfly spring
Standby normal reset, the reset effect produced better than hydraulic reset device, and butterfly spring are convenient for changing, price material benefit.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the present invention.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of pipe end expanding machine, including cone 1, voussoir 5, T-shaped block 11, support plate 10, dish
Spring 12 and pull bar 13.Described pull bar 13 sequentially passes through locking nut 4, nut 3, oil distribution casing 2, cone 1 and support plate 10, institute
The locking nut 4 stated is fixedly connected with nut 3, and nut 3 is fixedly connected with oil distribution casing 2, and oil distribution casing 2 is fixedly connected with cone 1, institute
Locking nut 4, nut 3, oil distribution casing 2, cone 1 and the support plate 10 stated are fixedly connected with pull bar 13 respectively, described oil distribution casing 2
Oil line pipe be connected with the oil line pipe of cone 1, the end face of voussoir 5 is provided with scrap scraping plate.Described voussoir 5 passes through the company of slip
Female connector is in cone 1, and described cushion block 6 is fixed on the outer surface of voussoir 5 by round key 8, and described secter pat 7 passes through round key 8
The outer surface of cushion block 6 is fixed on, anticollison block 9 is installed on secter pat 7, T-shaped block 11 can be effectively protected, it is to avoid expanding mistake
Steel pipe end surface causes to damage to T-shaped block 11 in journey.
The circular arc end face and the circular arc end face of the formation of T-shaped block 11 that described voussoir 5, cushion block 6 and secter pat 7 is constituted are consolidated
