Abstract

The utility model provides an adjustable punch structure. Operating length of a punch can be adjusted according to depth of a required hole to be punched, and the trouble that a plurality of types of punches are needed in machining due to nonuniform hole depths is avoided. The adjustable punch structure comprises a plurality of punches and a slider, wherein the punches are mounted in mounting holes of the slider. The adjustable punch structure is characterized in that the punches are fixed to the slider through lateral fastening screws. The adjustable punch structure is fine in universality and convenient in use, equipment cost is reduced, and production cost is further reduced.

Description

A kind of punch structure of regulating

Technical field

The utility model relates to formation of tubes die device field, is specially a kind of punch structure of regulating.

Background technology

Car seat framework such as backing tube, headrest part, bottom holder crust, draw pipe is cast spare, in process according to design often need the pipe fitting bending, flatten, otch and punching, general punching is that pierce punch is installed in mould, by the punch press matched moulds by pierce punch punching on cast spare.General mold and punching head structure, it is fixed in drift in the slide block, and slide block is fixed in module, dashes two above adjacent circular holes or square hole continuously at the place of flattening after cast spare is flattened, and needs punching several times in the past, and working (machining) efficiency is low; And because after cast spare flattens, it is flattened the two-layer tube wall in place and fits, the hole that the hole that has in adjacent holes is through hole, have only is the single wall perforation, it adds and not only needs punching processing several times man-hour, also need to change drift, to satisfy the requirement of the punching degree of depth, working (machining) efficiency is low, the drift that needs the configuration plurality of specifications is to satisfy the requirement of the punching degree of depth, the equipment configuration cost height.

Summary of the invention

At the problems referred to above, the utility model provides a kind of punch structure of regulating, it can regulate the drift active length according to the hole depth of required punching, avoid adding in the past and need to be equipped with multiple drift man-hour owing to hole depth is inconsistent, versatility is good, easy to use, reduced equipment cost, reduce production costs simultaneously.

Its technical scheme is such, and it comprises drift and slide block, and described drift is installed in the installing hole of slide block, it is characterized in that: described drift is provided with a plurality of, and described a plurality of drifts are fixed in described slide block by the side fastening screw.

It is further characterized in that: two drifts are installed in the described slide block at least; Described two drifts comprise fixedly drift and can regulate drift; Described fixedly drift is by the fixing described slide block of side fastening screw; The drift the regulated installing hole afterbody of described slide block is provided with adjustment screw; The described drift side of regulating is equipped with stop screw and trip bolt.

It further is characterised in that: the described locating surface of regulating drift is the plane; Have groove in the described plane of orientation.

A kind of punch structure of regulating of the present utility model, it can carry out the punching processing of a plurality of adjacent holes simultaneously, simultaneously when hole depth is inconsistent, can can regulate the length of drift by regulating the adjustment screw adjustment that can regulate the drift afterbody, thereby satisfy the hole depth processing request, its versatility is good, do not need to dispose and change the drift of many specifications, thereby effectively improve working (machining) efficiency, reduce the part deployment cost, reduce production costs.

The specific embodiment

See Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, it comprises drift and slide block 1 the utility model, and drift is installed in the installing hole of slide block 1, and drift is provided with a plurality of, and a plurality of drifts are fixed in the slide block 1 by side fastening screw 4.Two drifts are installed in the slide block 1 at least; Two drifts comprise fixedly drift 2 and can regulate drift 3; Fixedly drift 2 passes through fixedly slide block 1 of the firm screw 4 in side; The drift the regulated installing hole afterbody of slide block 1 is provided with adjustment screw 5; Can regulate drift 3 sides stop screw 6 and trip bolt 4 are installed.See that the locating surface 9 that Fig. 4, Fig. 5 and Fig. 6 can regulate drift 3 is the plane, it can prevent the drift rotation; Have groove 10 in the plane of orientation 9, it can prevent that trip bolt 4 from becoming flexible back punching head and being pulled out the slide block fixed position by stripping force.In use,, rotate adjustment screw 5, promptly can regulate the length that to regulate drift 3, reach the requirement of processing hole depth when running into the processing hole depth when inconsistent.When regulating punch structure and being installed on the mould endoporus, stop screw 6 plays position-limiting action when whole.Among Fig. 1 and Fig. 2,7 are the fixing removal hole of

drift

2, and 8 is the fixing safetied pin of drift 2.

Claims

1. can regulate punch structure for one kind, it comprises drift and slide block, and described drift is installed in the installing hole of slide block, it is characterized in that: described drift is provided with a plurality of, and described a plurality of drifts are fixed in described slide block by the side fastening screw.

2. a kind of punch structure of regulating according to claim 1 is characterized in that: two drifts are installed in the described slide block at least; Described two drifts comprise fixedly drift and can regulate drift; Described fixedly drift is by the fixing described slide block of side fastening screw; The drift the regulated installing hole afterbody of described slide block is provided with adjustment screw; The described drift side of regulating is equipped with stop screw and trip bolt.
