Description
Technical field
The present invention relates to automobile Manifold technology field, in particular to a kind of motor petrol fuel dispenser system rectangular tube punching
Hole location chamfer mould afterwards.
Background technique
Medium-to-high grade for motor vehicle petrol engine is now all made of conventional rectangular pipe, to improve fuel responsive speed, improve combustion
Expect mixed-precision, to reach higher combustibility, raising engine performance is simultaneously energy saving, and in its fuel dispenser system
In, main oil pipe is rectangular tube with holes.After rectangular tube punching, need to usually chamfering be carried out to hole punched, but rush in the prior art
Chamfering behind hole, usually machining mode is processed, and processing charges is high, and production efficiency is low.
Summary of the invention
The purpose of the invention is to overcome hole location after motor petrol fuel dispenser system rectangular tube punching in the prior art
Chamfering is high using processing charges present in machining mode, the low problem of production efficiency and a kind of motor petrol fuel oil is provided
Hole location chamfer mould after distribution system rectangular tube punching reduces cost to guarantee the efficiency of chamfering.
In order to solve the above technical problems, the technical scheme adopted by the invention is that:
Chamfer mould after a kind of punching of motor petrol fuel dispenser system rectangular tube, including piercing die, the piercing die
Including upper die component and lower mold assemblies；The upper die component includes cope plate, the red needle fixed plate being fixed on the cope plate
With the stripper of guide sleeve, several red needles, sliding configuration that are fixed in the red needle fixed plate in the red needle；The red needle
Across the stripper；The lower mold assemblies include lower template, the lower die holder being fixed in the lower template and guide post, are mounted on
Plug on the lower die holder, the guide post are slidably matched with the guide sleeve；When punching, the motor petrol fuel dispenser system
Rectangle pipe sleeve is on the plug, using the up and down motion of red needle in the motor petrol fuel dispenser system rectangular tube punching,
It is characterized in that, being provided with punching head and corner portion, the chamfering towards that one end of the lower mold assemblies in the red needle
Portion is located at the top on the punching head.
In a preferred embodiment of the invention, it is fixed with limited post in the lower template, utilizes the limited post
To control the size of the formed chamfering of the corner portion.
In a preferred embodiment of the invention, the central axis of the corner portion, punching head central axis with
The central axis of the red needle is overlapped.
In a preferred embodiment of the invention, one end of the plug is provided with limited block.
Due to using technical solution as above, fallen after the punching of motor petrol fuel dispenser system rectangular tube of the invention
Corner portion is directly arranged in angle mold in red needle, complete chamfering while punching.The present invention uses machining after solving punching
Efficiency present in chamfering is slow, and problem at high cost ensure that chamfering after the punching of motor petrol fuel dispenser system rectangular tube
Form and dimensional precision.
Detailed description of the invention
Fig. 1 be motor petrol fuel dispenser system rectangular tube of the present invention punching after chamfer mould structural schematic diagram.
Fig. 2 is enlarged diagram at the A of Fig. 1.
Specific embodiment
The present invention is further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, chamfering mould after a kind of punching of motor petrol fuel dispenser system rectangular tube shown in figure
Tool, including piercing die, the piercing die include upper die component 100 and lower mold assemblies 200.
Upper die component 100 includes cope plate 110, the red needle fixed plate 120 being fixed on cope plate 110 and guide sleeve 130, consolidates
The stripper 150 of several red needles 140, sliding configuration in red needle 140 being scheduled in red needle fixed plate 123；Red needle 140 is passed through and is unloaded
Flitch 150；Stripper 150 is used for discharging.
Lower mold assemblies 200 include lower template 210, the lower die holder 220 being fixed in lower template 210 and guide post 230 and limit
Position column 240, the plug 250 that is mounted on lower die holder 220, guide post 230 are slidably matched with guide sleeve 130；It is set in one end of plug 250
It is equipped with limited block 260.
When punching, motor petrol fuel dispenser system rectangle pipe sleeve is on plug 250 and is pushed into the limit of 250 one end of plug
Block 260, using the up and down motion of red needle 140 in motor petrol fuel dispenser system rectangular tube punching.
In order to overcome hole location chamfering after motor petrol fuel dispenser system rectangular tube punching in the prior art to use machining
Processing charges present in mode is high, the low problem of production efficiency, the present invention red needle 140 towards lower mold assemblies 200 that
One end is provided with punching head 141 and corner portion 142, and corner portion 142 is located at the top on punching head 141.In corner portion 142
Mandrel line, punching head 140 central axis be overlapped with the central axis of red needle 140.Motor petrol fuel distribution of the invention
Corner portion 142 is arranged in chamfer mould directly in red needle 140 after the punching of system rectangular tube, and corner portion is utilized while punching
142 complete chamferings, chamfering precision are high.
The present invention controls the size of the formed chamfering of corner portion 142, the size of chamfering using the height of limited post 240
It is easily controllable.
