Description
Technical field
The utility model device belongs to the mould manufacturing field that adopts Equal Channel Angular Pressing changeable type metal material.More be applicable in the sectional dimension that does not change ingot casting cogging and bar, and can realize type is become the grain refinement miter angle extruding deforming mould device of material.
Background technology
In existing metallurgical industry was produced, the cogging of ingot casting still generally was to adopt forging or milling method to carry out.This processing method is broken the column crystal in the material cast sturcture by the deformation to metal bar, and then adopts heat treatment method to make processed metal material can obtain uniform tissue.Adopt forging method then to require forging ratio to be greater than 3, and forging method can cause the sectional dimension of ingot casting that quite big change is arranged.In addition to the crystal fining method of no phase-change metal material, at present also be by forging or the rolling method of crystallization treatment again that reaches subsequently, the whole section deformation of bar is all even to be avoided occurring mixed crystal and takes place in order to make, then require processed metal bar that the certain deformation amount is arranged, so also can cause the variation of workpiece sectional dimension.Having is exactly that forging, rolling mill practice all can make the work piece surface produce very big tension again, and the metal material that is out of shape for difficulty cracks for avoiding, and then needs to adopt many fiery preparation methods that forge.So the shortcoming of said method is the preparation procedure complexity, characteristics such as the big and production cost height of technique controlling difficulty.
Summary of the invention
It is simple and production cost is low that the purpose of this utility model provides a kind of preparation technology, do not changing workpiece size and realizing the mould of metal works grain refinement usefulness miter angle extruding deforming metal material.
The mould of the miter angle extruding deforming that is proposed according to the utility model device, its objective is to solving is adopting flow of metal processing that workpiece is obtained in the process of uniform crystal particles refinement, do not changing or do not reducing under the situation of workpiece cross dimensions, make metal works when distortion, obtain enough big shear strain, and technology is simple and operation easily.
Above-mentioned purpose according to the utility model device, principle and technical scheme that we proposed to deal with problems are, by ingot casting or bar being carried out reduction of process such as cogging forging that deformation obtains grain refinement, roll forming, and adopt the production method of miter angle extruding deforming to solve weak point of the prior art.By the die device of miter angle extruding deforming that the utility model proposes, the operation principle of this device be with blank (ingot casting or bar) after crimp, do not change the cross dimensions of workpiece.When adopting the utility model device to act on processed blank, because the time through two passage junctions, born very large detrusion, therefore dislocation density in the interior tissue of blank is then significantly improved, the working hardening of the degree of depth has taken place in processed blank inside, in high-temperature heat treatment process subsequently, by the variation of the crystallization again in working, as-cast structure can be transformed into the crystal grain of perfect recrystallization, finally realize the grain refinement of organizing of bar.
Above-mentioned purpose and operation principle according to the utility model device, the concrete solution that we proposed can be described in detail with reference to the accompanying drawings: the composition of the utility model miter angle extruding deforming metal material die device, mainly form as accompanying drawing 1 by 5 parts, in the passage of the upper end of former 1, pressure ram 2 is housed, passage in the former 1 is the L type, blank 6 is finished crimp in the promotion of pressure ram 2 along L type passage, it is characterized in that in the side passage of former 1, knockout pin 3 being housed, limited block 4 is equipped with at the passage place of knockout pin 3 sides in former 1, and dressing stick 5 is equipped with at the blank 6 discharge port end passage places in former 1.Other features of the utility model device also have the W2 center, limited block 4 position of being equipped with of sliding in former 1 be circle hole shape, and position W1 front end is an opening.The dressing stick 5 be equipped with that slides in former 1 is a circle hole shape at the end of position of center line W4, is surface plate at the other end of position W3 center line.In former 1 passage, be equipped with on the knockout pin of knockout pin 3 and have and the identical stopper slot of limited block 4 front position W1 opening sizes.
Below we according to the accompanying drawing of the mould of the utility model miter angle extruding deforming metal material, the course of work of device is described in detail.Working procedure and structure according to this device, we are at first with the fixing knockout pin 3 (the position W1 by limited block 4 blocks knockout pin 3) of limited block 4, make the passage in the former 1 form L shaped passage, use pressure ram 2 extrusion billets 6 then, before treating that blank 6 will arrive the lower channel outlet, insert dressing stick 5 (W3 blocks channel outlet by the position), shift limited block 4 onto position W2 then, knockout pin 3 can be slided in hole, passage garden, with knockout pin 3 extrusion billets 6 to dressing stick 5, make that the front end of blank 6 is smooth shifts dressing stick 5 onto position W4 then to improve lumber recovery, make the exit passageway hole of blank 6 in former 1 to squeeze out.
Adopt the mould of the utility model miter angle extruding deforming metal material to compare with the production method of prior art, have that preparation technology is simple, reliable, practicality and production cost be low, do not changing workpiece size and realizing the metal works grain refinement, the product of preparation possesses performance and uniformity all is better than the product that art methods is produced.The utility model die device is provided with the knockout pin 3 that increases the demoulding and limited block 4, dressing stick 5, adopt this design to take mould apart and directly take out blank, so this mould advantages such as the shaping effect of production efficiency of products, blank and lumber recovery that are significantly improved.Because using the die device of the utility model miter angle extruding deforming produces, its preparation technology has changed traditional production method, the product workpiece do not need through forges, roll, the machined supervisor, so significantly reduced raw material and production cost.
