Abstract
The utility model relates to a kind of adjustable straight tube punching jigs, including lower plate and upper cover plate, it is connected with guide rod with guide sleeve, there is punching die in centre, mold includes punch upper die and punching lower die, punching lower die is bolted in lower die support shaft, and lower die support shaft is bolted on support frame, and support frame is bolted on lower plate.The demand of different-diameter pipe difference punching hole diameter diameter can be realized by replacement punching die.There is scale guide rail below lower die support shaft, there is baffle between lower die support shaft and scale guide rail, adjustable baffle plate is limited in lower die support shaft and scale guide rail by guide groove, adjusts distance of the punching relative to pipe end face.To sum up by disassembly mold and adjustable baffle plate, the punching position of different tube diameters, the adjusting of punching hole diameter are realized.The utility model structure is simple, compact to design, easy to use, by a variety of adjustings of jig, reduces the investment of punching die, saves punching die Meteorological.
Description
Technical field
The utility model relates to a kind of adjustable straight tube punching jigs, belong to punching techniques field.
Background technique
Motor vehicle exhaust emission regulation it is increasingly strict, exhaust aftertreatment technology is the technical measures that must be used.And it encapsulates
Involved bend pipe or straight tube connection in the process, operative sensor connector designs on pipe, so needed out on pipe
Sensor connector hole, usual processing technology are drilling or punching.Drilling device requirement is low, but low efficiency and low precision.Punching
Mode is high-efficient, the disadvantage is that die cost is high.
Summary of the invention
Purpose of the utility model is to solve the costly problems of punching die, provide a kind of be adjusted and adapt to not
The adjustable punching jig of same caliber, different pore size and different location punching demand.
The utility model adopts the following technical solution: a kind of adjustable straight tube punching jig, including lower plate, the bottom
Support frame is installed on plate, lower die support shaft is installed on support frame as described above, punching lower die, the branch are installed in the lower die support shaft
Installation guide rod on support, sliding setting guide sleeve, the guide sleeve are mounted in upper cover plate on the guide rod, peace among the upper cover plate
Fill punch upper die.
The lower die is transversely mounted by bolt in the middle part of support frame as described above as a further improvement of the utility model, to support
Axis.
The lower die support shaft is the column that section is arc surface as a further improvement of the utility model,.
The punching lower die is installed by bolt in the lower die support shaft as a further improvement of the utility model,.
The punching lower die is the column that section is arc surface as a further improvement of the utility model,.
Support frame as described above two sides are symmetrically installed guide rod as a further improvement of the utility model,.
The guide sleeve is hollow cylindrical as a further improvement of the utility model,.
Stiffening plate is installed in the punch upper die side as a further improvement of the utility model,.
Limiting device is installed as a further improvement of the utility model, the limiting device includes on the lower plate
Scale guide rail, sliding setting baffle on the scale guide rail.
Support frame as described above is vertical with the scale guide rail as a further improvement of the utility model,.
The utility model compared with prior art, has the advantages that
1, the utility model has the advantages of simple structure and easy realization, easy to use, by a variety of adjustings of jig, reduces punching
The investment of punch die saves punching die Meteorological.
2, the utility model passes through graduation position of the mobile block on scale guide rail, adjusts punching relative to pipe end face
Distance.To sum up by disassembly mold and adjustable baffle plate, the punching position of different tube diameters, the adjusting of punching hole diameter are realized.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Structural schematic diagram when Fig. 2 is utility model works.
Specific embodiment
Specific embodiment of the present utility model is further described with reference to the accompanying drawing.
In Fig. 1-2, including punch upper die 1, upper cover plate 2, stiffening plate 3, guide sleeve 4, support frame 5, guide rod 6, punching lower die 7,
Lower die support shaft 8, baffle 9, scale guide rail 10, pipe 11, lower plate 12.
As shown in Figure 1, the utility model is a kind of adjustable straight tube punching jig, including lower plate 12, on lower plate 12
Support frame 5 is installed, lower die support shaft 8 is transversely mounted by bolt in the middle part of support frame 5, lower die support shaft 8 is that section is arc surface
Column, punching lower die 7 is installed by bolt in lower die support shaft 8, punching lower die 7 also be the column that section is arc surface, is propped up
5 two sides of support are symmetrically installed guide rod 6, and sliding setting guide sleeve 4, guide sleeve 4 are hollow cylindrical on guide rod 6, and guide sleeve 4 is symmetrically mounted on
In upper cover plate 2, punch upper die 1 is installed, punch upper die 1 exposes 2 bottom surface of upper cover plate, and is located in punching lower die 7 among upper cover plate 2
Side.In order to enhance the installation strength of punch upper die 1 Yu upper cover plate 2, carried out in the side of punch upper die 1 by installation stiffening plate 3
It reinforces.
Limiting device can also be increased on lower plate 12 to increase in punching required punching relative to pipe end face distance
Stability and accuracy.Limiting device includes the scale guide rail 10 that lower plate 12 is arranged in that side of lower die support shaft 8, in this reality
It is vertical with scale guide rail 10 to apply support frame 5 in example.Sliding setting baffle 9 on scale guide rail 10,9 lower part of baffle is provided with leads with scale
The notch that rail 10 is adapted to, and scale guide rail 10 can be fixed by bolts in.In the present embodiment baffle 9 be in Y type, 9, baffle
In the lower section of lower die support shaft 8,9 upper surface of baffle is adapted to 8 bottom surface of lower die support shaft.
The course of work of the utility model is as follows: as shown in Fig. 2, firstly, as needed pipe processing size and shape,
Corresponding punch upper die 1 and punching lower die 7 are installed；Gear is moved relative to the distance of pipe end face then according to required punching
Block 9 is locked after the graduation position on scale guide rail 10；Then pipe 11 punching lower die 7 is touched to be pushed into contact with block 9；Most
After operate punching machine, punch upper die 1 pumps, complete punching operation.
