Abstract
The utility model relates to a track type automatic splitting/merging forging die. For the current general forging die, usually an upper and a lower sides are used for extruding, which forms burrs of a forge work piece and causes material waste and complicated processing technology. In the utility model, the front and the back sides of a core die sleeve are provided with taper keys, while the right and the left sides are respectively provided with T-shaped slide blocks; corresponding to the core die sleeve, the matching surfaces of an outer die sleeve are respectively provided with tapered slots and T-shaped slots. In company with the downward movement of an upper punch, two splitting/merging surfaces of the core die are gradually pressed tightly without a gap, causing no feed escape or no burrs. Simultaneously, through the cooperation of components arranged on the core die sleeve and the outer die sleeve, a horizontal punch is pushed to extrude materials to fill the die cavity for forming. Following the upward movement of the upper punch, all components move round about to realize automatic die ejection. The utility model has the advantages of reasonable design, raw material saving, high work efficiency, etc.
Description
Affiliated technical field
The utility model relates to a kind of railway type automatic open-close forging mould, is particularly useful for the manufacturing of forging pipe fitting with holes.
Background technology
The forging mould of general manufacturing enterprise all is that upper and lower surface pushes, and generally all forms the overlap of forging workpiece between its mould, forms the waste of material of the thing that is stamped, and the processing technology complexity.Owing to be the upper and lower surface extruding, extrusion molding is difficult on other side simultaneously, and processing brings great inconvenience to workpiece.Therefore, people wish to have a kind of mould that can overcome above-mentioned shortcoming to come out.
Summary of the invention
The purpose of this utility model is to provide a kind of railway type automatic open-close forging mould, and it pressurize for the many sides of workpiece simultaneously, and makes and pressed workpiece not produce overlap.
The utility model is achieved through the following technical solutions, it comprises formations such as core fixation clip, upper punch, core, core cover, outer die casing, right T type slide block, right drift, push rod, push rod guide pin bushing, left T type slide block, left drift, taper key, skewed slot, T type groove, the two sides is provided with taper key before and after the core cover, respectively be provided with T type slide block on the two sides, the left and right sides, outer die casing and core overlap and are respectively equipped with skewed slot and T type groove on the corresponding mating surface.
The utlity model has reasonable in design, save advantages such as former material, operating efficiency height.
Description of drawings
Accompanying drawing 1 is the utility model front view.
Accompanying drawing 2 is the utility model vertical view.
Accompanying drawing 3 is the utility model left view.
In the accompanying drawing, 1 for core fixation clip (being fixed on 4) with 3,2 for upper punch (being fixed on the active force equipment), 3 for core, 4 for core cover (1,3,4 cut open be two) along F-F, 5 for outer die casing, 6 for right T type slide block, 7 for right drift, 8 for workpiece, 9 for push rod, 10 for push rod guide pin bushing (cuing open along F-F is two), 11 for left T type slide block, 12 is left drift, 4-A/B:A is the taper key on the core cover 4; B is the skewed slot on outer die casing 5.2-T:T is the T type groove on the outer die casing 5.
Specific embodiment
As shown in drawings, after the material after the heating entered die cavity, drift 2 was under the effect of active force, and extruding makes raw material do pyroplastic deformation downwards, is crowded with die cavities and is shaped.And in the time of drift 2 extruding downwards, under the effect of downward extruding force, two inclined-planes of core cover 4 are along the two inclined-planes trace operation downwards of outer die casing 5.Make 3 two deciliters faces of core press tighter and tighter, no gap is not caused and is run material and overlap.After upper punch 2 makes component shaping by the stroke that mixes up in advance, upper punch 2 promotes up, two connecting rods on the upper punch headstock drive its accessory device rises push rod 9, head on core cover 4 and left and right sides T type slide block and drive left and right sides drift rising, and to both sides separate (this moment in uphill process, two taper key A of core 4 liang of each that face directly of cover face each two skewed slot B directly along 5 liang of outer die casings and move upward, make core 3 simultaneously, core cover 4 is made parallel split movement to both sides, about two T type slide blocks 11,6 T type grooves on the outer die casing 5 rise, and drive left and right sides drift 12,7 and break away from workpiece).After stopping by predetermined stroke, take out workpiece 8.Start attached pneumatic means, the loose piece under the push rod 9 is offed normal, and makes push rod 9 unsettled, and core 3, core cover 4, the track by the original rising in deadweight edge under no external force effect freely fall, and finish matched moulds and reset.Its process moves in circles like this.
