Description
Technical field
The present invention relates to a kind of mold head, especially a kind of punching press riveted joint down tilt mold head belongs to the press technical field.
Background technology
In prior art, because the reasons in structure of riveted joint die device all is earlier curved miter angle during riveted joint, and then carries out the technology of down tilt, need two procedures to accomplish like this, operating efficiency is lower.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, provide a kind of and can reduce unnecessary operation, reach a step accomplish overturning process purpose, increase work efficiency, reduce the punching press riveted joint down tilt mold head of manufacturing cost.
According to technical scheme provided by the invention, said punching press riveted joint down tilt mold head comprises upper bolster, flange drift, die shoe, fixed block, edge cover and reference column; Die shoe is arranged on the below of upper bolster, and the flange drift is fixedly mounted on the upper bolster, on die shoe, is installed with fixed block; Be installed with the edge cover on the fixed block; Put at edge and to offer slide opening, in slide opening, be slidingly fitted with reference column, in the edge cover, be provided with back-moving spring; The bottom of described reference column is sitting on the back-moving spring, it is characterized in that: the top ends at reference column is provided with depression; The end section of described flange drift is the inverted conical section; The top end face diameter of described inverted conical section is greater than the width of depression, and the one smooth connection has the roundlet shell of column above the inverted conical section, and the one smooth connection has the great circle shell of column above the roundlet shell of column; The junction of inverted conical section and roundlet shell of column has fillet; The junction of roundlet shell of column and great circle shell of column has fillet, and inverted conical section, roundlet shell of column be coaxial setting with the great circle shell of column, and the diameter of great circle shell of column is greater than the diameter of roundlet shell of column; The diameter of roundlet shell of column equals the top end face diameter of inverted conical section, and the diameter of roundlet shell of column is less than the diameter of slide opening.
Described depression is an inverted cone-shaped, and the axis coaxle of the center line of said inverted cone and reference column.The tapering of described depression is identical with the tapering of inverted conical section, and the height of inverted conical section is greater than the degree of depth of depression.
The present invention can reduce unnecessary operation when work, reach the purpose of step completion overturning process, has improved operating efficiency effectively, has reduced manufacturing cost.
Description of drawings
Fig. 1 is an overall structure sketch map of the present invention.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure, the present invention mainly is made up of parts such as upper bolster 1, flange drift 2, inverted conical section 2.1, roundlet shell of column 2.2, great circle shell of column 2.3, reference column 3, depression 3.1, edge cover 4, slide opening 4.1, fixed block 5, die shoe 6 and back-moving springs 7.
This punching press riveted joint down tilt mold head comprises upper bolster 1, flange drift 2, die shoe 6, fixed block 5, edge cover 4 and reference column 3, and die shoe 6 is arranged on the below of upper bolster 1; Flange drift 2 is fixedly mounted on the upper bolster 1; On die shoe 6, be installed with fixed block 5, be installed with edge cover 4 on the fixed block 5, on edge cover 4, offer slide opening 4.1; In slide opening 4.1, be slidingly fitted with reference column 3; In edge cover 4, be provided with back-moving spring 7, the bottom of described reference column 3 is sitting on the back-moving spring 7, is provided with depression 3.1 in the top ends of reference column 3; The end section of described flange drift 2 is an inverted conical section 2.1; The top end face diameter of described inverted conical section 2.1 is greater than the width of depression 3.1; The one smooth connection has roundlet shell of column 2.2 above inverted conical section 2.1; The one smooth connection has great circle shell of column 2.3 above roundlet shell of column 2.2, and inverted conical section 2.1 has fillet with the junction of roundlet shell of column 2.2, and roundlet shell of column 2.2 has fillet with the junction of great circle shell of column 2.3; And inverted conical section 2.1, roundlet shell of column 2.2 are coaxial setting with great circle shell of column 2.3; The diameter of great circle shell of column 2.3 is greater than the diameter of roundlet shell of column 2.2, and the diameter of roundlet shell of column 2.2 equals the top end face diameter of inverted conical section 2.1, and the diameter of roundlet shell of column 2.2 is less than the diameter of slide opening 4.1.
Described depression 3.1 is an inverted cone-shaped, and the axis coaxle of the center line of said inverted cone and reference column 3.The tapering of described depression 3.1 is identical with the tapering of inverted conical section 2.1, and the height of inverted conical section 2.1 is greater than the degree of depth of depression 3.1.
The inverted conical section 2.1 of flange drift 2 must be through peripheral polishing; Inverted conical section 2.1 must have fillet and will pass through polishing with the junction of roundlet shell of column 2.2, and roundlet shell of column 2.2 must have fillet and will pass through polishing with the junction of great circle shell of column 2.3.
During work, upper bolster 1 is descending, and inverted conical section 2.1 struts part 8, and roundlet shell of column 2.2 played the flange effect with the fillet elder generation of the junction of great circle shell of column 2.3 after drift got into lining then, leans on the bottom leveling of great circle shell of column 2.3 to realize that a step flange puts in place again.
