Abstract
The utility model belongs to the technical field of processing. The smear metal of adopting internal thread ring sword and presetting lead -out plate is expected the export and is solved smear metal material queueing problem, adds generally through the realization of adjustment handle of a knife structure is manual with the machine. The utility model relates to a special hole puncher of brittle material, its characterized in that: by constituteing in ring sword (1) and handle of a knife (2), the ring sword is fixed in the handle of a knife bottom, sets up the smear metal material that has lead -out plate (3) between handle of a knife and the ring sword and derives mouthful (4), and lead -out plate arranges ring sword top and ring sword hole smooth transition in, and ring sword inner wall sets up helical guide path (5). The utility model relates to a special hole puncher of brittle material, simple structure, convenient to use, easy and simple to handle, the security good, has reduced the manufacturing cost of enterprise. Be applicable to punching of brittle material, the punching of specially adapted phenolic foam plastics product.
Description
Technical field
This utility model belongs to processing technique field, relates to drilling technique field, particularly relates to fragile material cheesing techniques.
Background technology
In prior art, adopting mechanical punching, but for fragile material, owing to material fragility is big, easily collapse limit or fracture with mechanical punching, what have needs repairing, loses time, and efficiency is low；Directly discarding of having causes very big waste, adds production cost, also have impact on the presentation quality of product simultaneously.
Summary of the invention
The problem that the purpose of this utility model is in that to provide a kind of fragile material mechanical punching easily spring limit or fracture.
For solving above-mentioned technical problem, adopt the chip material outlet of female thread annulus cutter and preset derivation plate to solve chip material queueing problem, realized manually by adjustment cutter handle structure and machine adds general.
The fragile material special-purpose punching device that this utility model relates to, it is characterized in that: be made up of annulus cutter 1 and hilt 2, annulus cutter is fixed on bottom hilt, the chip material outlet 4 deriving plate 3 it is provided with between hilt and annulus cutter, derive plate be placed in above annulus cutter with annulus cutter inner hole smooth transition, annulus cutter inwall arranges spiral guide slot 5, and as shown in Figure 1, annulus cutter cross-section structure is as shown in Figure 2 for structure.
The fragile material special-purpose punching device that this utility model relates to, it is characterised in that: for overall circular tube structure, one end is annulus cutter 1, the other end is hilt 2, the built-in derivation plate 3 of chip material export mouth, derivation plate one end is concordant with the top of chip material export mouth, in smoothing junction with chip material export mouth opposite wall body.
The fragile material special-purpose punching device that this utility model relates to, it is characterised in that: being made up of annulus cutter and hilt, annulus cutter 1 is fixed on bottom hilt 2, hilt surface configuration anti-skid structure 6.
The fragile material special-purpose punching device that this utility model relates to, it is characterised in that: being made up of annulus cutter and hilt, annulus cutter 1 is fixed on bottom hilt 2, and described annulus cutter 1 cutting edge is tooth-shape structure.
The fragile material special-purpose punching device that this utility model relates to, it is characterised in that: being made up of annulus cutter and hilt, annulus cutter 1 is fixed on bottom hilt 2, and described tooth-shape structure is the one in triangle or arc structure.
The fragile material special-purpose punching device that this utility model relates to, it is characterised in that: described hilt 2 is drill chuck attachment structure.
The fragile material special-purpose punching device that this utility model relates to, simple in construction, easy to use, easy and simple to handle, safety is good, reduces the production cost of enterprise.Suitable in the punching of fragile material, it is particularly well-suited to the punching of phenolic foam product.
Accompanying drawing explanation
The fragile material special-purpose punching device structural representation that Fig. 1 this utility model relates to
The fragile material special-purpose punching device cross-sectional view that Fig. 2 this utility model relates to；
Wherein, 1-annulus cutter, 2-hilt, 3-derives plate, 4-chip material export mouth, 5-spiral guide slot, 6-anti-skid structure.
Detailed description of the invention
In order to be better understood from technique scheme, below in conjunction with Figure of description and specific embodiment, the technical solution of the utility model is described in detail, but not as the restriction to technical scheme.
For a kind of integral tubular structure card punch, technical scheme of the present utility model is described in detail, structure as it is shown in figure 1, overall in hollow cylinder shape and inside have separation, top is hilt 2, and bottom is annulus cutter, and centre arranges the outlet of chip material.
Card punch overall length 85mm, external diameter 27mm, be processed into by the stainless steel tube of wall thickness 2mm.The gum cover of the long bore coupling of one end suit length 35mm is as hilt anti-skid structure, and the breach opening 30mm below anti-skid structure 6 exports 4 as chip material, derives plate and is placed in breach and contacts with tube wall；The other end processes cutting edge as endless knife end, and inside tube wall below breach to processing pitch between endless knife cutting edge be the screw thread of 20mm as dregs guiding groove, obtain the manual punch that this utility model relates to.
The lamina tecti of high 2mm circular arc also can be set at top, it is simple to holds pressing etc..
During use, first, workpiece is placed on platform, holds the hilt of card punch, the card punch tooth shape edge of a knife is directed at position to be processed and carries out manual pressure operation, make the card punch tooth shape edge of a knife contact with fragile material, complete drilling process.Reduce by the card punch tooth shape edge of a knife with fragile material contact surface, slow down impulsive force, fragile material is made not easily to collapse limit or fracture, reduce the production cost of enterprise, improve product quality, card punch body side chip material exit design, chip material is made to discharge in time, it is easy to continuous operation, handbar design anti-slip veins, not easily slip out of the hand, the ratio that operates is relatively labor-saving, improves production efficiency.
It addition, by changing cutter handle structure, it is possible to achieve manually and machining mode general.
Furthermore, adopt the Split assembled structure of hilt and endless knife, it is achieved the exchange of different bore cutter heads.
