Abstract
The invention discloses a blade forging die facilitating detection of offset of a forged piece. The blade forging die comprises an upper die and a lower die, wherein at least two upper inserts used for detecting offset are fixed on the upper die, an upper offset groove is formed in each upper insert, and the end surfaces of the upper offset grooves are flush with the end surface of the upper die; at least two lower inserts used for detecting the offset are fixed on the lower die, a lower offset groove matched with the corresponding upper offset groove is formed in each lower insert, and the end surfaces of the lower offset grooves are flush with the end surface of the lower die; each offset groove comprises four side groove surfaces and one bottom groove surface, and the four side groove surfaces of each offset groove all adopt a planar structure. During forging, an offset block blank made of a metal material is put in each offset groove. The inserts are arranged on the die, the offset grooves with the side groove surfaces adopting the planar structure are formed in the inserts, all that is required for determination of offset of the forged piece is to detect the offset of an offset block forged along with the forged piece, operation is convenient and simple, and the offset detection efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of mould, particularly relate to a kind of blade forging mould being convenient to detect forging offsetting amount.
Background technology
In blade forging forming process, the stressed comparatively complexity of blade forging mould, huge forming force must cause mould to be subject to larger side force, thus causes producing inconsistent phenomenon between upper and lower mould.In actual production, because blade construction is complicated, the blade profile distortion of blade is larger, the mould offsetting amount that simultaneously out-of-shape such as blade root, boss, integral shroud causes detects very difficult, and detection time is longer, if dislocation is larger, even need again to try forging, greatly reduce the efficiency of forge, thus, be badly in need of solving.
Summary of the invention
The object of the invention is to for the problems referred to above, provide a kind of blade forging mould being convenient to detect forging offsetting amount, to solve the offsetting amount detection difficult of existing blade forging mould, detection time is long, the problem of impact forging efficiency.
The object of the invention is to be achieved through the following technical solutions:
A kind of blade forging mould being convenient to detection forging offsetting amount, comprise patrix, counterdie, described patrix is fixed with at least 2 for detecting the upper inserts of offsetting amount, described upper inserts has offsetting groove, the end face of described upper offsetting groove and patrix end face, described counterdie is fixed with at least 2 for detecting the lower inserts of offsetting amount, described lower inserts has the lower offsetting groove matched with upper offsetting groove, the end face of described lower offsetting groove and counterdie end face, described offsetting groove is made up of 4 side channel faces and 1 kerve face, 4 described side channel faces are planar structure, during forging, offsetting groove is built-in is placed with offsetting compact material, described offsetting compact material is made up of metal material.
As a preferred embodiment of the present invention, described patrix is fixed with 2 upper inserts, is arranged in patrix blade root place, patrix integral shroud place respectively, accordingly, described counterdie is fixed with 2 lower inserts.
As a preferred embodiment of the present invention, the kerve face of described offsetting groove is planar structure.
As a preferred embodiment of the present invention, described offsetting compact material is made up of aluminum.
Beneficial effect of the present invention is, described a kind of blade forging mould being convenient to detect forging offsetting amount passes through to arrange inserts on mould, and on inserts, offer the offsetting groove that side channel face is planar structure, and then only need detect the offsetting amount of the offsetting block forged with forging, the offsetting amount of forging can be determined, convenient and simple for operation, substantially increase offsetting amount detection efficiency.

Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.Be understandable that, embodiment described herein is only for explaining the present invention, but not limitation of the invention.
Please refer to shown in Fig. 1 to Fig. 3, Fig. 1 is a kind of upper die structure schematic diagram being convenient to the blade forging mould detecting forging offsetting amount of the present invention; Fig. 2 is a kind of lower die structure schematic diagram being convenient to the blade forging mould detecting forging offsetting amount of the present invention; Fig. 3 is the structural representation of offsetting block.
In the present embodiment, a kind of blade forging mould being convenient to detection forging offsetting amount, comprise patrix, counterdie, described patrix has 2 for detecting the upper inserts 1 of offsetting amount, be arranged in patrix blade root place respectively, patrix integral shroud place, described upper inserts 1 has offsetting groove 2, the end face of described upper offsetting groove 2 and patrix end face, accordingly, counterdie has 2 lower inserts 3, be arranged in counterdie blade root place respectively, counterdie integral shroud place, described lower inserts 3 has the lower offsetting groove 4 matched with upper offsetting groove 2, the end face of described lower offsetting groove 4 and counterdie end face, described offsetting groove 2, 4 are made up of 4 side channel faces and 1 kerve face, 4 described side channel faces are planar structure, described kerve face is planar structure, during forging, offsetting groove 2, 4 are built-inly placed with offsetting compact material, described offsetting compact material is made up of aluminum.
The above-mentioned blade forging mould being convenient to detection forging offsetting amount, respectively at patrix, the blade root of counterdie, integral shroud place arranges inserts 1, 3, and at inserts 1, the offsetting groove 2 that side channel face is planar structure is offered on 3, 4, during forging, offsetting block can be forged in company with forging, as shown in Figure 3, offsetting block is by upper piece 5, overlap 6 and lower piece 7 formation, upper piece 5, overlap 6, be structure as a whole for lower piece 7, by principle of six-point fixing, offsetting block is located on detection fixture, because after offsetting block withdrawing pattern, withdrawing pattern end face is not smooth, thus, in following piece 7, the end face of non-withdrawing pattern one end is datum level, the end face of above piece of 5 non-withdrawing pattern one end is detection faces, employing slide measure detects, the distance detected deducts the offsetting amount that theoretical value is offsetting block, and then the offsetting amount of forging can be determined, easy to operate, simply.
Above embodiment has just set forth general principle of the present invention and characteristic; the present invention does not limit by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
