Description
Technical field
The utility model relates to technical field of forging, particularly relates to a kind of tool structure for annular forging piece flat-die forging.
Background technology
Personal forging utilizes impulsive force or pressure to make metal all directions Free Transform between upper and lower anvil face, unrestricted and obtain a kind of processing method of required form and size and certain mechanical performance forging.Forging reaming is in the past that workman clamps forging with pliers and gyrates, and the labour intensity of workman is very high, and production efficiency is lower, and the rotation amplitude of forging grasps by workman's experience, the situation that the forging wall unevenness after easily forging is even.Utility model patent 201220438971.0 discloses a kind of flat-die forging major diameter lopps reaming forging apparatus, solves the problems referred to above, but this forging apparatus complex structure, it is not convenient to use.
Utility model content
The deficiency that the utility model exists for prior art, provides a kind of structure simple, improves the tool structure for annular forging piece flat-die forging of Wall-Thickness Difference precision.
The utility model provides a kind of tool structure for annular forging piece flat-die forging, comprises saddle support, semicircle, half round shaft and tup, it is characterized in that, also comprise wall thickness pad; Described saddle support has two supporting parts accepting described semicircle, and described semicircle has first end and the second end being connected described half round shaft, and described first end and described the second end are placed on two supporting parts of described saddle support respectively; Described wall thickness pad is placed on described the second end, coordinates with it the limiting section of formation control Wall-Thickness Difference.
This tool structure is simple, uses assembling easy.When forging blank rotary motion does not reduce in continuation to forging wall thickness, no matter hammer hitting power into shape much, utilize match with the semicircle limiting section of formation control Wall-Thickness Difference of wall thickness pad to carry out mechanical position limitation, in forging blank multiple rotary, meet the requirements of size and Wall-Thickness Difference, improve Wall-Thickness Difference precision.
As preferably of the present utility model, described the second end has the top that upwards extends and the bottom to downward-extension in its vertical direction; Described top offers the recess be connected with described wall thickness pad.
As preferably of the present utility model, described wall thickness spacer has forced section and lug boss.
As preferably of the present utility model, the lug boss of described wall thickness pad be from described forced section junction to the structure broadened gradually with described recess junction; Described recess is the structure suitable with described lug boss.
As preferably of the present utility model, described lug boss is dovetail configuration.
As preferably of the present utility model, the width of described forced section is equal with the radial width of described semicircle.
As preferably of the present utility model, the height of described forced section is the spacing height of described limiting section.
The utility model has following beneficial effect:
It is few that the utility model is used for the tool structure building block of annular forging piece flat-die forging, and structure is simple, and dismounting is convenient, utilizes match with the semicircle limiting section of formation control Wall-Thickness Difference of wall thickness pad to carry out mechanical position limitation, the precision of raising Wall-Thickness Difference.

Detailed description of the invention
As Fig. 1-3, the tool structure for annular forging piece flat-die forging comprises saddle support 1, semicircle 2, half round shaft 4 and tup 5.Described saddle support 1 has two supporting parts accepting described semicircle 2.Described semicircle 2 has and is placed on first end 21 on described two supporting parts and the second end 22 respectively, and for the pars intermedia through annular forging piece blank 3.Described tup 5 is just arranged described annular forging piece blank 3.Described the second end 22 connects described half round shaft 4.
Because the size of each hitting power of tup 5 is different with the position of rotation of forging blank 3, the difference Wall-Thickness Difference of forging blank 3 differs greatly, and in order to reduce forging surplus and tolerance, arranges wall thickness pad 6.Described wall thickness pad 6 is placed on described the second end 22, coordinates the limiting section of formation control Wall-Thickness Difference with described the second end 22.Wherein, described the second end 22 has the top 221 that upwards extends and the bottom 222 to downward-extension in its vertical direction.Described bottom 222 is for contacting with the supporting part of described saddle support 1, and described top 221 contacts with described wall thickness pad 6, and described top 221 has the recess 2211 be connected with described wall thickness pad 6.Described wall thickness pad 6 has the forced section 61 that tup 5 acts on and the lug boss 62 matched with described recess 2211.As preferably, the lug boss 62 of described wall thickness pad 6 be from described forced section 61 junction to the structure broadened gradually with described recess 2211 junction; Described recess 2211 is the structure suitable with described lug boss 62, such as described lug boss 62 can adopt dovetail configuration, the concave structure of described recess 2211 is suitable with dovetail configuration, so not only make to be fastenedly connected between described wall thickness pad 6 and described semicircle 2, depart from after not being subject to hammer force, and easily change wall thickness pad 6.In order to make good limit effect, Wall-Thickness Difference controls precisely, and the width also arranging described forced section 61 is further equal with the radial width of described semicircle 2.
When forging blank 3 is hit in hammering, along with the rotation of blank, wall thickness is more and more less, and when tup hits wall thickness pad 6, the wall thickness of forging blank 3 no longer continues to reduce, no matter hammer hitting power into shape much, wall thickness is remained unchanged by mechanical position limitation, in forging blank 3 multiple rotary, meet the requirements of size and Wall-Thickness Difference, and the height of described forced section 61 can be the spacing height of described limiting section, improve than thick poor precision, staving press can be adopted after base to carry out rolling.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
