Abstract
The utility model relates to a hole forming tool, in particular to a precise gasket hole forming device. The precise gasket hole forming device mainly solves the technical problems that due to manual direct hole opening, gaskets cave and the hole shapes are not regular. According to the technical scheme, the precise gasket hole forming device is characterized by comprising a guide plate and a female die, the guide plate is an organic glass transparent piece, the guide plate and the female die are fixed through positioning pins, and the guide plate and the female die are respectively provided with multiple rows of through holes with various diameters, gaskets at the same height are arranged on the positioning pins between the guide plate and the female die, and cylindrical puncher pins matched with the through holes are assembled in the through holes with various diameters. The cylindrical surface of each puncher pin is in a stepped shape, the diameter of the front knife edge portion is larger than that of the rear guiding potion, a hole is punched at the center of the bottom face of the knife edge portion, a guide block is arranged in the hole, the head portion of the guide block is in a frustum shape, the tail portion of the guide block is provided with a split elastic piece, the tail portion of the guide block is inserted into the punched hole, and the guide block and the puncher pins are matched so that it can be ensured that precise gasket inner holes are concentric with external circles. Each puncher pin is provided with a protection sleeve. Cross scales are scratched on each through hole of the female die. The hole forming tool is used for gasket hole forming.
Description
Technical field
The utility model relates to a kind of drilling tool, particularly a kind of fine gasket hole making drill.
Background technology
Perforate on pad at present, adopts bur for handwork directly to punch more, and pad, due to stressed, can produce depression, is difficult to obtain the hole of compound standard, particularly at all cannot perforate for shim liner.In the time of operation, line that cannot see pad easily causes perforate deviation in addition.And also cannot process concentric pad.How to obtain and a kind ofly can on fine gasket, open various diameters and standard compliant hole is exactly the problem that the utility model will be studied.
Summary of the invention
The purpose of this utility model is to provide a kind of fine gasket hole making drill, and mainly the manual directly perforate of solution exists the technical problem of pad depression and pass irregularity.
The technical solution of the utility model is: a kind of fine gasket hole making drill, it is characterized in that comprising guide plate and die, described guide plate is lucite transparent member, guide plate and die are fixed by alignment pin, on guide plate and die, have the through hole of the various diameters of many rows, on the alignment pin between guide plate and die, be provided with contour pad, the through hole of various diameters is furnished with the cylinder of matching drift.Described drift cylinder is step, anterior edge of a knife section diameter is greater than the targeting part diameter at rear portion, the punching of edge of a knife part bottom center, in hole, settle guide pad, guide pad head is taper type, afterbody is jag flexure strip, and afterbody inserts in bore of the punch, and guide pad coordinates guarantee fine gasket endoporus concentric with cylindrical with drift.Injure hand when preventing perforate, each drift is equipped with a protective jacket, described protective jacket intermediate throughholes, and both sides are indent arc.For ease of aiming at, draw intersection cross scale in each through hole of die.
Useful technique effect of the present utility model is: the utility model is that a tool is multiplex; can meet pad and open the hole of various diameters; due to by between pad folder and guide plate and die; in the time of punching, can not produce distortion; fine gasket perforate needs are met; guide pad coordinates with drift and ensures that fine gasket endoporus is concentric with cylindrical, and protective jacket has protected that point can be not injured.

Detailed description of the invention
With reference to Fig. 1,2,3, a kind of fine gasket hole making drill, comprise guide plate 3 and die 5, described guide plate 3 is lucite transparent member, guide plate 3 and die 5 are fixing by alignment pin 6, the through hole 9 that has the various diameters of many rows on guide plate 3 and die 5 is provided with contour pad 7 on the alignment pin 6 between guide plate 3 and die 5, and the through hole 9 of various diameters is furnished with the cylinder of matching drift 1.Described drift 1 cylinder is step, anterior edge of a knife section diameter is greater than the targeting part diameter at rear portion, the punching of edge of a knife part bottom center, in hole, settle guide pad 8, guide pad 8 heads are taper type, afterbody is jag flexure strip, and afterbody inserts in bore of the punch, and guide pad 8 coordinates guarantee fine gasket endoporus concentric with cylindrical with drift 1.Injure hand when preventing perforate, each drift is equipped with a protective jacket 2, described protective jacket intermediate throughholes, and both sides are indent arc.For ease of aiming at, draw intersection cross scale in each through hole of die.
Operating procedure: mark on fine gasket 4 and want the position of perforate or draw the profile that needs machining hole, in the middle of fine gasket is put into hole making drill, be that die 5 and guide plate 3 are middle, visual pad line or aim at the position of required machining hole according to the cross scale on guide plate, put into check the number big or small drift 1 and protective jacket 2, gently hold up drift 1 with 2 fingers, knocking drift 1 top makes drift 1 pour die 5 throughhole portions, then remove protective jacket 2 and pick up utensil and rap again drift and make drift 1 depart from die 5, finish the work.
As processed concentric circles, first select the drift 1 of hole size in required concentric circles to do pre-punched hole, then select the drift of concentric circles cylindrical size to coordinate the guide pad 8 of interior hole size, locate the concentric circles that rushes in advance endoporus with guide pad 8, make required concentric circles pad.
