Description
Technical field
The utility model is related to car panel die field more particularly to a kind of car panel die trimming and piercing dies
Structure.
Background technology
In general, the processing of car panel die parts, the especially more complicated parts in some surfaces, mainly according to
It is processed by copy milling, with the parts of profiling Milling Machining, not only precision is low, but also efficiency is also very low, the labor intensity of worker
Greatly, the manufacturing cycle of mold is long.
Utility model content
The purpose of this utility model is that defect according to prior art, provides a kind of car panel die trimming and piercing die
Mode structure, what the technical solution of the automobile covering trimming punching mode structure was realized in：
A kind of car panel die trimming and piercing die mode structure, including upper die holder, eccentric swage, small stripper, piercing punch,
Inclined wedge, lower die holder, sliding block, waste material box, punching concave die structure.
The upper die holder is the component that work is driven by sliding block.
The lower die holder is located at the lower part of trimming and piercing die.
The piercing punch is connect with small stripper, and punching concave die is connect with eccentric swage, piercing punch and punching concave die
Double-faced clearance is 0.12mm.
The ratio between height and length of the inclined wedge are controlled in (0.6~0.8)：In the range of 1, between inclined wedge joint surface be 12~
15mm。
The sliding block is the punch structure driven by inclined wedge.
The eccentric swage is the structure for suppressing product.
The waste material box is to collect the device of the waste material generated in blanking process.
It is that small mould repair provides convenient device that the small stripper, which is on eccentric swage,.
Further, the ratio between height and length of the inclined wedge 0.7：1.
Further, the joint surface between inclined wedge is set as 13mm.
The advantageous effect of the car panel die trimming and piercing die of the utility model is：Selection reasonable design, is conducive to
Overall dimensions keep high-precision low cost.
Description of the drawings
Fig. 1 is a kind of car panel die trimming and piercing die structural schematic diagram.
Reference numeral：1- upper die holders, 2- eccentric swages, the small strippers of 3-, 4- piercing punches, 5- inclined wedges, 6- lower die holders, 7- are slided
Block, 8- waste material box, 9- punching concave dies.
Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of car panel die trimming and piercing die mode structure, including upper die holder 1, eccentric swage 2, the small material returned
Plate 3, piercing punch 4, inclined wedge 5, lower die holder 6, sliding block 7, waste material box 8, punching concave die 9.
The upper die holder 1 is the component that work is driven by sliding block 7.
The lower die holder 6 is located at the lower part of trimming and piercing die.
The piercing punch 4 is connect with small stripper 3, and punching concave die 9 is connect with eccentric swage 2, and piercing punch 4 and punching are recessed
The double-faced clearance of mould 9 is 0.12mm.
The ratio between height and length of the inclined wedge 5 are controlled in (0.6~0.8)：In the range of 1, the joint surface between inclined wedge 5 is
12~15mm.
The sliding block 7 is the punch structure driven by inclined wedge 5.
The eccentric swage 2 is the structure for suppressing product.
The waste material box 8 is to collect the device of the waste material generated in blanking process.
It is that small mould repair provides convenient device that the small stripper 3, which is on eccentric swage 2,.
When it is implemented, the ratio between height and length of the inclined wedge 5 0.7：1；5 joint surfaces of inclined wedge are set as 13mm.
When it is implemented, the sliding block 7 of presses drives 1 downlink of upper die holder, eccentric swage 2 first to contact article surface and gradual
Compress product；Upper die holder 1 continues traveling downwardly, and eccentric swage 2 is slack relative to lower die holder 6, and piercing punch 4 is under upper die holder 1
Row starts punching, while inclined wedge 5 pushes sliding block 7 forward, and side piercing punch 4 is pushed to move ahead, and starts punching.When punching terminates
When, press sliding block 7 reaches lower dead point position, and limiter limits its stroke, and punching terminates, and punch process is completed.When backhaul, sliding block
7 drive 1 uplink of upper die holder, and eccentric swage 2 presses against product and rests on lower die holder 6 under the action of the spring, with spring pressure
Release finishes, and upper die holder 1 stays in product on lower die holder 6 with eccentric swage 2 together uplink.While 1 uplink of upper die holder,
The receding side punching concave die 9 under the action of retracting spring of sliding block 7, whole process are completed.
The technology contents and technical characteristic of the utility model have revealed that as above those skilled in the art still may base
The replacement and modification without departing substantially from the utility model in essence are made in the teaching of the utility model, therefore, the utility model protection
Range is not limited to the revealed content of embodiment, also includes various replacements and modification without departing substantially from the utility model in essence.
