Why is the saw bone machine with a device that automatically tensions the saw blade?
Why is the saw bone machine with a device that automatically tensions the saw blade? Before expounding this question, we need to review the initial heart: not forgetting the original heart, it must always be . Before the user purchases the bone saw machine, it may just want the bone saw machine, that is, the user wants to separate the frozen meat by the sawing machine, and the bone is cut neatly without broken bone residue, or is easy. To reach the desired length, it may be nothing more. But when the user uses the bone saw machine, the user's thoughts become: 1. Can the saw blade last longer? Is there a saw blade with a better price/performance ratio? 2. Can this meat (sawdust) be less? If you buy more meat, you can earn more if you can get more finished products. Of course there are other more ideas, which have nothing to do with this topic and are reserved for the next discussion. In fact, this is part of the intrinsic quality characteristics of the product, because the inherent quality characteristics of the product are divided into 1 applicability , 2 credibility , 3 economy , 4 aesthetics , 5 safety, the above two generated by the user after using the bone saw machine. The idea is exactly the embodiment of both products 1 and 3 . If the experience is not perfect, then the quality characteristics of this bone saw machine are not perfect, that is, there is a lack of certain aspects. In terms of 1 applicability requirement, designing a bone saw machine is actually to solve two problems. 1. In the non-cutting state, the machine and the saw blade are stable at high speed (line speed 20-30m/s) and the blade shake is small. 2. In the cutting state, the machine and the saw blade are stable at high speed (line speed 20-30m/s) and the saw blade shake is small. From the perspective of 2 credibility requirements, designing the saw bone machine is also a component structure and material selection problem. From the perspective of economic requirements, the design of the sawing machine itself must have relatively economical costs in order to meet the requirements of various requirements in order to obtain market competitiveness, that is to say, it can provide users with more economical machines; On the other hand, it is also necessary to take into account the economics of the user's use, such as the saw blade of the consumables and the minced meat of the material loss category. ④ just from the aesthetic requirements in terms of design saw bone machine is to make the machine has beauty and flavor of the times. From the perspective of 5 safety requirements, the design of the saw bone machine is to meet the requirements of a certain standard. Danniu Beijing's bone sawing machine is designed according to European standards. It involves more safety and electrical safety. Noise, mechanical operation, food hygiene and many other aspects of safety. It is true that the above five quality characteristics are not isolated, but interact and influence. Some people say that product quality is manufactured , this is true, but this is just a broad concept. The designer of Danniu Beijing believes that the quality of the product is first designed ! I will talk about it here today. When Daniel (Beijing) Machinery Technology Co., Ltd. designs the bone saw machine, why should the hydraulic rod automatically tension the saw blade? There are still many ways to tighten the saw blade saw blades on the market: there is a screw straight connection; there is a lever connection to tighten; there is a tension spring tension; there is a compression spring tension; The butterfly spring is used; there is a eccentric wheel. Some of the above tensioning methods appeared earlier and are still being used today; some tensioning methods know that it is not good, but due to structural and cost reasons, those tensioning methods are still adopted. So what is the reason? Let the Dan cattle sawing machine use the hydraulic rod to automatically tighten it? This is because: 1. This device is easy to replace the saw blade Move the long handle of the illustration to loosen or tension the saw blade, which is very fast. When the saw blade is not in the middle of the upper wheel, adjust the five-star handle on the long handle to place the saw blade in the middle position of the upper wheel, so that the saw blade is in a better working condition. 2. This device is easy to reach design indicators In the design, Dan cattle sawing machine has been carefully calculated, retrieved a lot of scientific research papers, and found the excellent tension index of the longest fatigue time of the saw blade, but only knowing that the excellent tightening force is useless, how can we make it The sawing machine is in the hands of the operator and the perfect tension is the perfect machine. Selecting the screw direct connection is definitely not possible, because different operators have different strengths and different feelings. Only a non-human operation mode can be used to achieve this effect. It is theoretically reasonable to use springs or transcendental clutches, but The strength of the spring and the overrun is different due to the spring itself, so it is difficult to reach the design index, and the Dan cattle sawing machine solves this problem by using the hydraulic rod. The figure shows the “force-displacement†curve of the hydraulic rod: From this "force-displacement" diagram, During its effective working stroke, the change of the tension is less affected by the displacement, which means that the tension can allow the length of the saw blade to change within a certain range (such as the length of the saw blade welding length, long-term use of the saw blade is elongated Etc., in order to achieve the effect of automatic adjustment, rather than relying on the operator to adjust the tensioning handle by experience or feeling, no need to adjust or tighten the operator, this design is to automatically adjust the tension. Because the change in tension is small, the tension on the cross section of the saw blade is also constant, which makes it very easy to meet the excellent tension requirements of the design. 3. This device brings a real experience to the user. 3.1 It is precisely because the change of the tension of the hydraulic rod is very small, the saw blade has been working under the excellent tension of the design, so the service life of the saw blade is naturally extended, instead of being shortened, the user's saw blade is not Then it costs. 3.2 At the same time, because the saw blade is automatically tensioned, the saw blade has small jitter, and the saw blade has small jitter to design a guide block with smaller gap. The Dan cattle sawing machine adopts the wear-resistant guide block of Zhuanli products, which not only has a small design gap. At the same time, due to wear resistance, a small gap is maintained for a long time, and the guide block can also assist the saw blade to be more stable. Small jitter will bring two benefits: First, extend the use time of the saw blade, reduce the cost of consumables, and reduce costs; second, reduce material loss, improve yield, and increase profits. 3.3 Due to the stability, not only the gap is small, but also a thin saw blade is used, the kerf is small, the yield is greatly improved, and the profit rate is improved.
