Description

Revolve the hole saw structure-improved

The utility model relates to a kind of hole saw structure-improved that revolves, and more particularly, is meant that especially a kind of manufacturing funds are low, speed of production fast with the hole saw that revolves with certain product quality.

In the past revolve that the hole saw manufacture method made revolve the hole saw structure-improved, see also shown in Figure 1, first kind of hole saw manufacture method of revolving commonly used, be earlier material punching out on steel plate to be formed round sheet, and punching out goes out through hole 12 and through hole 13, at this moment, just can forge into cup-shaped body 10 and axis hole 14 through machinery, then just need the work that the milling machine system of milling is revolved hole saw sawtooth 11 is delivered in work, see also shown in Figure 2, experienced staff's one tooth one tooth will revolve hole saw sawtooth 11 mill make after, many times have been wasted, at last work is delivered in the heat treatment facility and heat-treated, but, the hole saw manufacture method of revolving that this kind is commonly used still is subject to the work that the system of milling is revolved hole saw sawtooth 11, the whole working time can't be shortened, and the manufacturing funds are greatly improved, and mill the system of milling technology and the experience that the quality of making relies on the processing personnel fully because of revolving hole saw sawtooth 11, process personnel in experience so plant the manufacturer of revolving the hole saw manufacture method commonly used for milling machine, the energy that need cost a lot of money on training and the variety of issue to be met, and in the work that ensures product quality, also be not easy to arrive requirement, so in pursuing ideal, today of practicality and quality, really wait to make great efforts the progressive target of improving for a utmost point.

Another kind of commonly used revolve that the hole saw manufacture method made revolve the hole saw structure-improved, be to adopt pipe materials processing mode, pipe material with required caliber blocks into required height earlier, again work is delivered to the work that the milling machine system of milling is revolved the hole saw sawtooth, see also shown in Figure 2, after experienced staff's one tooth one tooth will revolve the hole saw saw-tooth milling cutter and make, many times have been wasted, and workpiece deliver to heat-treat in the heat treatment facility after, again will be mill teeth and hot worked pipe material sleeve on the tringle identical with its internal diameter, can utilize mechanical stamping to produce required chimeric trip and through hole this moment, but, the hole saw manufacture method of revolving that this kind is commonly used is subject to the work of milling the system sawtooth, the whole working time can't be shortened, and the manufacturing funds are greatly improved, and rely on processing personnel's technology and experience fully because of the quality of revolving the work of hole saw saw-tooth milling cutter system, process personnel in experience so plant the manufacturer of revolving the hole saw manufacture method commonly used for milling machine, need the energy and the funds that cost a lot of money on training and the variety of issue to be met, and in the work that ensures product quality, also be not easy to arrive requirement, and above-mentioned problem is to revolve the hole saw manufacturer at present to expect most the problem that solves.

In view of this, the inventor is through detailed think of funiculus, and accumulation is engaged in various hole saw instrument and the relevant experiences that sell, study, develop of revolving the hole saw equipment of revolving for many years, and it is low to develop a kind of manufacturing funds finally, speed of production soon and have certain product quality revolve the hole saw structure-improved.

Primary and foremost purpose of the present utility model, be to provide a kind of low production cost, speed of production fast with have certain product quality revolve the hole saw structure-improved, the utility model is to utilize the step of punching press to make simultaneously to set out to revolve the hole saw sawtooth, chimeric trip and through hole, so revolve and can not be subject to the work of milling the system sawtooth when hole saw is made, the whole working time is shortened dramatically, manufacturing funds and product price reduce, and because of the quality of revolving hole saw sawtooth punching out work is the precision that relies on processing equipment, so adopt the new manufacturer of revolving the hole saw manufacture method of this kind for the processing personnel in experience, training is less with variety of issue to be met, manufacturing funds and product price can be reduced once more again, and in the work that ensures product quality, also very easy arrival requirement is so be that a kind of manufacturing funds are low really, speed of production fast with have certain product quality revolve the hole saw structure-improved.

The purpose of this utility model provides a kind of hole saw structure-improved that revolves.

The purpose of this utility model is achieved in that a kind of hole saw structure-improved that revolves, be to make preset number with punching press to revolve hole saw sawtooth, the chimeric trip of preset number and preset number through hole, and hollow cylinder to be welded into after the crooked clamping of anchor clamps, the sawtooth of preset number is at its lower edge, and the chimeric trip of preset number edge thereon.The chimeric trip of this preset number can be L type blocking hole.

In sum, the utility model provides a kind ofly revolves the hole saw structure-improved, and the utility model is a foundation basically: (1). cutting step: (2) punch steps; (3). the mould step of curling: (4). welding step; (5) heat treatment process; By above-mentioned manufacturing step, can produce the cheap and good-quality hole saw that revolves, not only can solve to produce when the system of in the past milling is revolved the work of hole saw sawtooth and lose time and the problem that increases the use facility, and can solve in the past the manufacturer for milling machine processing personnel in experience, training and variety of issue to be met, no longer need to be dependent on processing personnel's experience, making sawtooth is undertaken by precision optical machinery fully, can ensure product quality, and because of reducing the work of mill teeth one by one, can reduce outlay of production and production unit cost, so to be a kind of speed of production really fast and with low cost revolves the hole saw structure-improved for the utility model.
