Description

Thin-walled square tube bracket piercing die
Technical field
The utility model belongs to metalwork processing mould field, relates to a kind of processing mold, specifically a kind of punching die of thin-walled square tube support.
Background technology
Auto industry, in the economic development of developed country, plays a part mainstay.Auto industry is the industry of highly technology-intensive type, and concentrate new material, new equipment, new technology and the new technology in many scientific domains, the development of auto industry will inevitably promote the development of many related industries departments.Auto industry is comprehensive assembly industry, and an automobile is made up of ten million kind of parts and components, and wherein, metalwork is the topmost parts of automobile.
Stamping parts of automobile, as the term suggests, form the metallic stamping pieces of auto parts and components exactly.In stamping parts of automobile, a part directly becomes auto parts and components after punching press, and another part also needs just can become auto parts and components after welding or the processes such as machining or paint after punching press.In the machining of later process, perforating die is the most frequently used equipment of metalwork hole machined.Mould Machining has unicity, and a kind of mould can only process a kind of product usually, and different mould also can adopt different structural designs according to the design feature of different product.Thin-walled square tube, due to himself reasons in structure, is not enough to impulsive force when supporting punching, causes the distortion of thin-walled square tube machined surface, cause the instability of product quality.
Utility model content
The purpose of this utility model is the punching die providing a kind of thin-walled square tube support.
The purpose of this utility model can be achieved through the following technical solutions:
Thin-walled square tube bracket piercing die, comprises upper die and lower die, and described patrix comprises the die shank being arranged on cope match-plate pattern side and the punch retainer being arranged on cope match-plate pattern opposite side and guide pin bushing, and punch retainer is fixed with pierce punch; Described counterdie comprises and is fixed on guide pillar on lower bolster and die block, die block is provided with die and the positioning core axle between two location-plates, two location-plates are all provided with stripper plate, positioning core axle and stripper plate are provided with the hole slot that arrange corresponding to die, and pierce punch is corresponding with hole slot to be arranged.
One end of described positioning core axle is flexibly connected with bearing pin by two risers be oppositely arranged, and two risers are positioned at die block side.
Described guide pin bushing and guide pillar are two, and homonymy correspondence is arranged.
Described pierce punch and die are four, and pierce punch one end is vertically fixed on punch retainer, and the other end is corresponding with die to be arranged.
The beneficial effects of the utility model: the utility model structural design is simple, rationally, stamping die folding speed is fast, and working (machining) efficiency is high, and structural design is compact, small volume, is convenient to mould and installs and uses and mould customized management.
Accompanying drawing explanation
The utility model to be further described below in conjunction with accompanying drawing for the ease of it will be appreciated by those skilled in the art that.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view after the utility model counterdie removes stripper plate.
Fig. 3 is the schematic diagram of the utility model stripper plate.
Detailed description of the invention
As shown in Figure 1 and Figure 2; the punching die of thin-walled square tube support; comprise upper die and lower die; patrix comprises the die shank 11 that cope match-plate pattern 10 upper side is arranged; the punch retainer 7 that downside is equipped with and guide pin bushing 9; punch retainer 7 is fixed with four pierce punches 6, and pierce punch 6 upper end is vertically embedded to be fixed on punch retainer 7; Counterdie comprises and is fixed on guide pillar 8 on lower bolster 1 and die block 3, die 2, riser 14, location-plate 12 and positioning core axle 13 die block 3 be equipped with, positioning core axle 13 is for fixing workpiece to be processed 4, positioning core axle 13 one end is flexibly connected by two risers 14 and bearing pin 15 being positioned at die block 3 side, positioning core axle 13 can rotate up and down, have simultaneously and serve as die effect when stamping-out square tube upper end face, realizing square tube two ends face can process simultaneously.Positioning core axle 13 both sides are equipped with location-plate 12 respectively, stripper plate 5 location-plate 12 is equipped with, shown in the present embodiment accompanying drawing 1-2, guide pin bushing 9 and guide pillar 8 are two, and on cope match-plate pattern 10, lower bolster 1, homonymy correspondence is arranged, pierce punch and die are four, pierce punch is corresponding with die to be arranged, and positioning core axle 13, stripper plate 5 is equipped with the hole slot corresponding with die, can finds out in Fig. 2, Fig. 3, both sides hole slot is square, and middle hole slot is circular.
Working method: workpiece to be processed 4 is placed on die block 3, to treat that the positioning core axle 13 that punching position passes through to rotate is located with die about 2, located by both sides location-plate about 12 again, pierce punch 6 undershoot of cope match-plate pattern 10, complete punch die operation, guide pin bushing 9 and the guide pillar 8 of setting play the guiding role.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
