Description
Technical field
The utility model relates to guardrail processing equipment, is specifically related to pipe fitting punching assembled mould.
Background technology
Guardrail uses extensively on urban architecture facility, plays the effect of protection isolation, the safety of the protection person, very important.In the production process of industrialization, in order to can in enormous quantities, the processing of mechanization, guardrail is generally designed to assembling form, and horizontal, vertical pipe fitting is individually processed, and then carries out Assembling connection.Man-hour is added to the pipe fitting of assembling guardrail, needs to carry out punching processing.For the core rod with holes of punching die, adopt steel alloy manufacture, its cost is higher.During batch machining pipe fitting, core rod loss with holes is still comparatively large, once loss must change monoblock core rod, not so can affect the quality of punching.Therefore mould loss is a larger cost payout of guardrail processing.Reduce the loss of mould, can production cost be reduced.
Summary of the invention
The utility model is the loss solving punching die, core rod, reduces production cost, devises a kind of assembled mould.
Design of the present utility model is as follows: pipe fitting punching assembled mould, comprise patrix, bed die, core rod and core rod cover, described core rod is arranged in core rod cover, the core rod hole place of core rod is provided with core rod punching block and installs groove, core rod slide block punching block embeds and is arranged on wherein, and core rod slide block punching block center arranges punching.; The bed die hole place of described bed die is provided with bed die punching block and installs groove, and bed die slide block punching block embeds and is arranged on wherein, and bed die slide block punching block center arranges punching.
The two side of core rod punching block installation groove is respectively arranged with core rod I-shaped chute, and two sides arrange core rod fin to core rod slide block punching block, core rod fin and core rod I-shaped chute matched in clearance, are embedded by core rod slide block punching block and are arranged in core rod punching block installation groove.
The two side of bed die punching block installation groove is respectively arranged with bed die I-shaped chute, and two sides arrange bed die fin to bed die slide block punching block, bed die fin and bed die I-shaped chute matched in clearance, are embedded by bed die slide block punching block and are arranged in bed die punching block installation groove.
Described core rod slide block punching block adopts alloy tool steel to be make.
Described bed die slide block punching block adopts alloy tool steel to be make.
During punching, in the core rod inserting pipe elements of mould, after patrix pressure, upper punch vent stem, through pipe wall, continues to pass through the punching of core rod slide block punching block and the punching of bed die slide block punching block, processes the assembly hole of pipe fitting.When the punching loss distortion of assembled mould, only need take off along bad core rod slide block punching block or bed die slide block punching block, change.Bed die, patrix, core rod and core rod cover adopts common iron to make, the mould that cost adopts alloy tool steel to make far below monoblock.Therefore only change core rod slide block punching block or bed die slide block punching block, change whole mould compared with original, its cost reduces much.
The utility model, by unitary mould, is designed to sectional die, and the die punching place only contacted with punching bar adopts the fritter slide block punching block embedded to adopt alloy tool steel to make, and greatly reduces the cost of core rod.The cost of core rod loss when processing guardrail pipe fitting because this reducing, thus reduce the production cost of guardrail.

Detailed description of the invention
Below in conjunction with specific embodiment and Figure of description, the utility model is described in further detail.Specific embodiment described herein only in order to explain the utility model, and is not used in restriction the utility model.
Embodiment: as shown in Fig. 1 ~ Fig. 7, pipe fitting punching assembled mould, overlaps 4 assemblings by patrix 1, bed die 2, core rod 3 and core rod and forms.As shown in Figure 1, patrix 1 is provided with punching bar 7.As shown in Figure 7, core rod 3 is arranged in core rod cover 4.As shown in Figure 4, the 3b place, core rod hole of core rod 3 is provided with core rod punching block and installs groove 3a, and core rod slide block punching block 5 embeds and is arranged on wherein, and core rod slide block punching block 5 center arranges punching.As shown in Figure 2, the 2b place, bed die hole of described bed die 2 is provided with bed die punching block and installs groove 2a, and bed die slide block punching block 6 embeds and is arranged on wherein, and bed die slide block punching block 6 center arranges punching.The punching of core rod slide block punching block 5 and bed die slide block punching block 6 is punching bar 7 matched in clearance with patrix 1, for punching processing.Therefore be the part of easy loss in mould, adopt alloy tool steel to be make, strengthen its durability.The patrix 1 of mould, bed die 2, core rod 3 and core rod cover is then made with common iron.
As shown in Figure 4, the two side of core rod punching block installation groove 3a is respectively arranged with core rod installing hole 3c, core rod slide block punching block 5 structure as shown in Figure 5, its two sides are arranged core rod semicircle fin 5a, core rod semicircle fin 5a and core rod installing hole 3c matched in clearance, embed core rod slide block punching block 5 and be arranged in core rod punching block installation groove 3a.Bed die 2 is same with bed die slide block punching block 6 to carry out installation according to said structure and combines.As shown in Figure 2, the two side of bed die punching block installation groove 2a is respectively arranged with bed die I-shaped chute 2c, and bed die slide block punching block 6 structure as shown in Figure 3, its two sides is arranged bed die fin 6a, bed die fin 6a and bed die I-shaped chute 2c matched in clearance.
Organize mould before processing, as shown in Figure 8, core rod is arranged in core rod cover, is then fixed on bed die by core rod cover.During processing pipe fitting, assembly type core rod, from the mouthpiece cover inlet pipe of pipe fitting, is placed in pipe fitting by core rod.Patrix is depressed, and punching bar penetrates pipe fitting, passes, process the installing hole of pipe fitting from the punching of core rod and bed die.Core rod, in pipe fitting, supports pipe fitting, by pipe fitting compressive strain when preventing from pressing down.Long-term processing, causes punching to damage or distortion, can affect punching quality, then change bed die slide block punching block and core rod slide block punching block, need not more mold exchange miscellaneous part.The steel alloy price of mfg. moulding die is higher, and combined type mold core can save the cost of core rod.
