Abstract
The utility model provides a novel withhold sword, includes the blade main part, be equipped with a plurality of mounting hole on the lateral wall of blade main part, be equipped with the arch on the upper surface of blade main part, bellied top is equipped with the cutting edge, blade main part, arch, cutting edge integrated into one piece, blade main part, arch, cutting edge all adopt the spring steel to make, have greatly improved the hardness and the toughness of withholding the sword, have avoided owing to withhold captain's time service and make and withhold the sword phenomenon of rupture and take place withholding the in -process.
Description
Technical field
The utility model relates to one and withholds cutter, particularly a kind of Novel buckle push type broach.
Background technology
In the process of some radiators, it is a kind of very important procedure of processing that mainboard is withheld, and is mostly in the market to adopt mainboard buckle machine to withhold mainboard.The cutter of withholding of traditional buckle machine used in the market is made of cast iron, there are some defects in the cutter of withholding of this material: because buckle machine works long hours, the cutting edge of adding the blade withholding cutter is thinner, make in the process of withholding, often withhold cutter and occur phenomenon of rupture, also can damage for machine and product itself.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and the utility model provides that a kind of structure is simple, reasonable in design, long service life, damage little Novel buckle push type broach to machine and product.
The utility model solves the technical scheme that its technical problem adopts: a kind of Novel buckle push type broach, comprise vane body, the sidewall of described vane body is provided with several installing holes, the upper surface of described vane body is provided with projection, the top of described projection is provided with blade, described vane body, projection, blade are one-body molded, and described vane body, projection, blade all adopt spring steel to make.
Adopt spring steel to make and withhold cutter, after spring steel heat treatment and Cold-draw Hardening, intensity is higher, has certain toughness and plasticity, and under similar face state and complete through hardening situation, fatigue limit is suitable with alloy spring; Adopt said structure, drastically increase the Hardness and toughness withholding cutter, avoid and make in the process of withholding, withhold the generation of cutter phenomenon of rupture because buckle machine works long hours.
As preferably, described projection is right-angled trapezium, and the bottom thickness of projection is less than or equal to the thickness of vane body, and between the inclined-plane of described projection and the upper surface of vane body, formed angle is 100 ° ~ 110 °.Adopt said structure, not only avoid blade owing to withholding cutter too thin thus cause withholding cutter phenomenon of rupture and occur, but also save rapidoprint, reduce production cost.
As preferably, between described projection and blade, formed angle is 160 ° ~ 170 °.Adopt said structure, make the external force that blade place is subject in the process of withholding more balanced, avoid the blade unbalance stress owing to withholding cutter thus cause withholding the generation of cutter phenomenon of rupture.
As preferably, the thickness of the cutting edge of described blade is greater than 2.0mm.Adopt said structure, thinner the making of the cutting edge avoiding the blade owing to withholding cutter often withholds the generation of cutter phenomenon of rupture in the process of withholding.
As preferably, described installing hole is two.Adopt said structure, the installation stability of withholding cutter is improved.
The utility model has that structure is simple, reasonable in design, long service life, to machine and product infringement little.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the utility model embodiment;
Fig. 2 is a kind of side view of the utility model embodiment.
Detailed description of the invention
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
A kind of Novel buckle push type broach as shown in Figure 1 to Figure 2, comprises vane body 1, and the sidewall of described vane body 1 is provided with two installing holes 2, and the installation stability of withholding cutter is improved; The upper surface of described vane body 1 is provided with protruding 3, described protruding 3 is right-angled trapezium, and the bottom thickness of protruding 3 is less than or equal to the thickness of vane body 1, between the described inclined-plane of protruding 3 and the upper surface of vane body 1, formed angle is 105 °, not only avoid blade owing to withholding cutter too thin thus cause withholding cutter phenomenon of rupture and occur, but also save rapidoprint, reduce production cost; The described top of protruding 3 is provided with blade 4, and between described blade 4 and protruding 3, formed angle is 165 °, makes the external force that blade place is subject in the process of withholding more balanced; The thickness position 3.0mm of the cutting edge of described blade 4, thinner the making of the cutting edge avoiding the blade owing to withholding cutter often withholds the generation of cutter phenomenon of rupture in the process of withholding; Described vane body 1, projection 3, blade 4 are one-body molded, described vane body 1, projection 3, blade 4 all adopt spring steel to make, adopt spring steel to make and withhold cutter, after spring steel heat treatment and Cold-draw Hardening, intensity is higher, have certain toughness and plasticity, under similar face state and complete through hardening situation, fatigue limit is suitable with alloy spring; Drastically increase the Hardness and toughness withholding cutter, avoid and make in the process of withholding, withhold the generation of cutter phenomenon of rupture because buckle machine works long hours.
In process of the test, adopt the cutter of withholding made of cast iron quality to damage after withholding the product of about 10000, and cutter of withholding provided by the utility model is withheld the life-span and can be reached about 18000; As can be seen here, service life of withholding cutter provided by the utility model is widely higher than the service life of withholding cutter adopting cast iron quality to make.
The utility model has that structure is simple, reasonable in design, long service life, to machine and product infringement little.
Above-described embodiment is one of the present utility model preferably scheme, not does any pro forma restriction to the utility model, also has other variant and remodeling under the prerequisite not exceeding the technical scheme described in claim.
