Abstract
The utility model discloses a sand tire core shaft mould used for processing thin-wall long sleeve, which comprises a sand tire core shaft, two ends of the gravel core shaft are arranged with shaft direction positioning hole, one end is provided with a step matched with the end part rabbet of the thin-wall long sleeve, and the other end is arranged with a slide block, a screw thread and a locking nut; after the thin-wall long sleeve and the sand tire core shaft of the workpiece is assembled, there's a space for fine sand filling is between the thin-wall long sleeve and the sand tire core shaft of the workpiece. The utility model is used for processing the thin-wall long sleeve with high processing accuracy and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of close-over mandrel mould, especially relates to a kind of close-over mandrel mould that is used for the processing of thin-walled long sleeve.
Background technology
At present, the processing of thin-walled long sleeve is all finished with swelling mandrel mould.Use swelling mandrel Mould Machining thin-walled long sleeve, form and position tolerance and dimension precision requirement height to thin-walled long sleeve spare itself, require also very high to the mandrel mould accuracy of manufacture; after the thin-walled long sleeve completion of processing; withdraw from the easy vibration deformation of mandrel mould; make thin-walled long sleeve difficult processing to reach the dimensional accuracy of regulation, influence product percent of pass, improved the mandrel die manufacturing cost simultaneously.
The utility model content
The purpose of this utility model is to overcome the above-mentioned defective of prior art, and a kind of thin-wall part machining accuracy that improves is provided, and reduces the close-over mandrel mould that is used for the processing of thin-walled long sleeve of die manufacturing cost.
The technical solution of the utility model is: it comprises the close-over mandrel, and the two ends of close-over mandrel are provided with the axial location hole, and an end has and the suitable step of the end seam of thin-walled long sleeve, and the other end is provided with slide block and screw thread and locking nut; After workpiece thin-walled long sleeve and the assembling of close-over mandrel mould, between workpiece thin-walled long sleeve and the close-over mandrel space that can pour into fine sand is arranged.
The beneficial effects of the utility model: owing between workpiece to be machined thin-walled long sleeve and close-over mandrel, the space is arranged, can pour into fine sand fills, thereby avoided long sleeve wall and close-over mandrel wall directly to contact the generation of poor fit situation, and fine sand has good absorbing effect, can effectively absorb shaking of producing in the processing can, thereby effectively avoid generation of vibration, solved the not high problem of thin-walled long sleeve machining accuracy; Low cost of manufacture.
Description of drawings
Fig. 1 is the front view of the utility model one embodiment.
Fig. 2 is an A--A cutaway view embodiment illustrated in fig. 1.
Fig. 3 is the workpiece thin-walled long sleeve schematic diagram in the close-over mandrel mould embodiment illustrated in fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1,2,3, present embodiment comprises close-over mandrel 1, and the two ends of close-over mandrel 1 are respectively equipped with axial location hole 6, one ends the step that matches with the end seam 7 of thin-walled long sleeve 5, and the other end has slide block 2 and screw thread and locking nut 3.After thin-walled long sleeve 5 and 1 assembling of close-over mandrel, the space 4 that can pour into fine sand is arranged between thin-walled long sleeve 5 and the close-over mandrel 1.
Add man-hour, the seam 7 of thin-walled long sleeve 5 one ends and the assembling of close-over mandrel 1 step, the seam 8 of the other end and 2 assemblings of the positioning sliding block on the close-over mandrel 1 are filled fine sand with the space 4 between thin-walled long sleeve 5 and the close-over mandrel 1, are fixed by locking nut 3.
In existing thin-walled long sleeve process, the difficulty of total length processing technology locating hole is very big, and the surface roughness and the accuracy of form and position are difficult to reach the required precision of technology locating hole.The utility model changes at the short seam technology of thin-walled long sleeve two ends processing locating hole, adopts the scheme of a clamping boring two ends fabrication hole.Its precision, surface roughness improve greatly, and difficulty of processing greatly reduces.
