Abstract
The utility model relates to a combined die forging upper punch which comprises a convex die and a fixing sleeve. A matching cylinder is arranged on the upper portion of the convex die. The matching cylinder is connected with the convex die through a section of transition cylinder. A matching counter bore is formed in the fixing sleeve, and a through hole is formed in the lower portion of the matching counter bore. The matching cylinder on the upper portion of the convex die is arranged in the matching counter bore in the fixing sleeve in a clearance fit mode. The convex die penetrates through the through hole in the lower portion of the matching counter bore and extends out of the fixing sleeve. The convex die and the fixing sleeve are positioned with the bottom face of the matching counter bore in the fixing sleeve in the axial direction through the lower end face of the matching cylinder on the upper portion of the convex die. The upper end face of the matching cylinder on the upper portion of the convex die is level with the upper end face of a flange on the upper portion of the fixing sleeve. The upper punch is divided into the convex die and the fixing sleeve in a split mode, and combination of the convex die and the fixing sleeve is achieved through the clearance fit between the matching cylinder on the upper portion of the convex die and the matching counter bore in the fixing sleeve. When the shape of the convex die is destroyed, the fixing sleeve only needs to be dismantled, the convex die is replaced, and then the fixing sleeve is installed again, and the upper punch can work again.
Description
Technical field
The utility model relates to a kind of die forging upper punch, and particularly a kind of fabricated structure of die forging upper punch belongs to mould design and manufacturing technology field.
Background technology
In the technology of heat (temperature) no-draft forging, the punch in the die forging upper punch is impact extruded heat (temperature) attitude metal blank many times, and the frictional force between punch shape face and the metal flow fiber is very big, so the metal flow fiber is also very big to the punch shape deterioration.In order to guarantee that the blank after the die forging adheres to specification, ruined punch must be changed immediately, so the replacing of upper punch is quite frequent, belongs to consumable accessory.The upper punch of heat (temperature) no-draft forging that has now and once had generally all is all-in-one-piece.Be provided with one section than the major diameter die shank on punch top, the seat that connects press slide is set in the end of die shank, and seat is fastened on the bottom face of press slide by bolt with setting shape.In case the punch shape is destroyed, whole upper punch is promptly declared to scrap.Such upper punch structure, difficulty of processing is big, consumptive material is many, use cost is high, does not meet the needs of Sustainable Development of Enterprises.Therefore, it is necessary to design the die forging upper punch that a kind of consumptive material is few, cost is low.
Summary of the invention
The purpose of this utility model is to provide a kind of assembly type die forging upper punch, remedies the existing technical deficiency that monoblock type die forging upper punch consumptive material is many, cost is high.
To achieve these goals, the utility model Bian implements with following technical scheme: a kind of assembly type die forging upper punch, comprise punch, fixed cover, the upper end of described fixed cover is provided with flange, the lower surface of its fixedly connected press slide, the top that it is characterized in that described punch is provided with the cooperation cylinder, cooperates between cylinder and the punch to be connected by one section transition cylinder; Be provided with the cooperation counterbore in the described fixed cover, cooperate the bottom of counterbore to be provided with through hole; The cooperation cylindrical gap on described punch top is engaged in the interior cooperation counterbore of fixed cover; Described punch passes from the through hole that cooperates the counterbore bottom and stretches out outside the fixed cover; Described punch and fixed cover axially between cooperates cylinder by punch top the interior counterbore bottom surface that cooperates of lower surface and fixed cover locate; Described punch top cooperates the upper surface of cylinder concordant with the upper surface of fixed cover upper flange.
The utility model is punch and fixed cover two parts with the upper punch split, and cooperates the interior matched in clearance form that cooperates between the counterbore of cylinder and fixed cover by punch top, realizes the combination of upper punch.After the punch shape is destroyed, as long as unload fixed cover, change punch, refill fixed cover, upper punch can be reworked.
The utlity model has advantage simple in structure, that replacing is convenient, the punch die consumptive material is few, processing cost is low.
Description of drawings
Fig. 1 is a main sectional structure schematic diagram of the present utility model;
In Fig. 1: 1 fixed cover, 101 cooperates counterbore, 102 through holes, 2 punch, 201, cooperates cylinder, 202 transition cylinders.
The specific embodiment
As shown in Figure 1, the top of punch 2 is provided with and cooperates cylinder 201, cooperates between cylinder 201 and the punch 2 to be connected by one section transition cylinder 202; Be provided with cooperation counterbore 101 in the fixed cover 1, cooperate the bottom of counterbore 101 to be provided with through hole 102; In the cooperation counterbore 101 of cooperation cylinder 201 matched in clearance in fixed cover 1 on punch 2 tops, punch 2 passes from the through hole 102 of fixed cover 1 bottom and stretches out outside the fixed cover 1; Punch 2 and fixed cover 1 axially between cooperates cylinder 201 by punch 2 tops lower surface and fixed cover 1 interior counterbore 101 bottom surfaces that cooperate locate; Punch top cooperates the upper surface of cylinder 201 concordant with the upper surface of fixed cover 1 upper flange.
The utility model is punch 2 and fixed cover 1 two parts with the upper punch split, and cooperates cylinder 201 and the fixed cover 1 interior matched in clearance form that cooperates between the counterbore 101 by punch 2 tops, realizes the combination of upper punch.After punch 2 shapes are destroyed, as long as unload fixed cover 1, change punch 2, refill fixed cover 1, upper punch can be reworked.
