Chapter 101: Improve broaching machine

The meaning of   Ishikuma is actually very simple. It is to change the slider directly pulled by manpower on this broaching machine to mechanical drive.

  The slider on the broaching bed is not small. The reason for this is to maintain the stability of the hook knife when pulling it. Therefore, coupled with the strong friction between the hook knife and the inner wall of the barrel and the deceleration mechanism under the broaching machine, this results in a great effort required to pull the slider.

  The change of Shixiong is to use a deceleration device composed of several wooden wheels to drive the hook knife. The core theory is that the small wheel is driven by manpower, and then the small wheel drives the big wheel in order to achieve the purpose of saving effort.

   Although this will reduce the speed of rifling, it can save energy greatly.

  Although Old Wood and Ferguson didn't understand the principle of reducer, they encountered almost the same things in their daily lives. So they will soon be able to figure out what the guardian-sama is saying.

"Boss, the method you said is indeed feasible, but there are still some things I don't understand. For example, if this improvement method is adopted, how should the barrel keep rotating during the rifling process? Also, ours What shape should the hook knife be made into? Besides..."

   Accompanied by a series of questions from Lieutenant Ferguson, Ishikuma also understood that although they understood the power output principle, they were still far from really coming up with this improved machine tool.

Shixiong actually doesn’t know how to do this kind of broaching machine. He just saw the working principle of the rifling machine on that video. If you ask him to tell him how to make this improved broaching machine, he’s really doing it. Not sure.

But it doesn’t matter. Whether it’s Ferguson or old wood, or the bunny mouth and hard bones behind Ferguson’s ass, they are all kind of people who are good at researching. Just tell them the principle. In terms of the researching personality of this group of guys, this The improved broaching machine should be available soon.

   "Come, come, come here, I will draw you a rough figure." Shi Xiong was also unambiguous, and directly called a few people to the broaching table.

  The sliding table of the broaching machine is very flat, so this sliding table is very good to be used as a drawing board.

   Hard Bone took out a piece of coal ground into a cylindrical shape from his pocket and handed it to Shi Xiong. This was a "charcoal pen" he specially ground out according to Shi Xiong's statement. No way, the tribe is so poor, there is no charcoal, so coal has to be used instead.

As a cultural preservation expert in his previous life, Shi Xiong's painting skills are quite good. Even if he holds a "charcoal pen" polished with coal, he draws down a few strokes, a simple but well-organized drawing machine. The bed appeared on the slider.

   This broaching machine looks much more compact than the current manual wooden broaching machine. Several wheels of different sizes are located in the middle of the broaching machine.

"These wooden wheels are actually similar to the deceleration device at the bottom of this broaching machine, but you still need to experiment many times to calculate the ratio between these wooden wheels, so as to ensure the final distance and speed of the rod movement. ."

   Lieutenant Ferguson nodded and said: "Boss, Mr. Mu and I already have experience with this kind of power transmission device, and we will do it well."

   Ishikuma nodded, and then continued: "Next, I will focus on how to make the hook knife move according to our wishes and the rotation of the barrel."

   Then Shi Xiong drew another picture on the free part of the slide according to the picture in the video that he had watched.

   This picture is actually a slotted shelf. A small slider is stuck in the middle of the slot. There are two connecting rods under the small slider, but Shixiong drew a "?" under one of the connecting rods.

"In fact, if you want to keep the barrel rotating at a constant speed, this problem is not difficult to solve. Look, if we install such a slotted device on the top of the tie rod screw. Well, this is a chute, and a chute can be freely stuck. The sliding slider, the slider is connected to the No. 1 connecting rod and the No. 2 connecting rod. When the chute is installed, there must be a certain slope, and then the No. 1 connecting rod is connected with the longest tie rod screw, then when When the big wooden wheel drives the tie rod screw forward, the No. 1 connecting rod will push the chute to move. Because the chute has a slope, when the slider moves, it will drive the No. 2 connecting rod up or down vertically. movement."

   Ishikuma combined the strokes and the drawing, and several people quickly figured out the working principle of this device. The working principle of this thing is not difficult. Even Indians like Old Wood and Rabbit Mouth, who have never received any education, can clearly figure out the working principle of this device.

Shixiong continued: "Look, as long as the tie rod screw moves forward and backward, then the No. 2 connecting rod can keep moving up and down. So can we install another device under the No. 2 connecting rod to control the rotation of the barrel? ."

   Ishixiong’s understanding of the video ends here~www.wuxiaspot.com~ and further down, he can't remember the video clearly. But at this point, most of the core problems can almost be solved.

   After all, this thing is a kind of mechanical energy exchange problem. It is nothing more than turning the lateral movement into a longitudinal movement or a circular movement. As long as it is controlled, it is not difficult to solve the problem of the fixed rotation of the barrel when the hook knife is rifled.

Sure enough, Lieutenant Ferguson, a generation of firearms genius, has a high talent for this aspect. After listening to Shixiong’s explanation, he only pondered for a while, then nodded and said: "Boss, we can install a belt under the No. 2 connecting rod. The cogging device or another set of small deceleration device is finally connected to the barrel, then the barrel can rotate at a uniform speed, but this still requires a lot of calculations and experiments."

After a pause, Lieutenant Ferguson said affirmatively: "Boss, if this broaching machine is improved according to your set of improvements, then I can conclude that the efficiency and accuracy of rifling will be greatly improved. For example, five or six of us pulled out only one barrel this afternoon and one afternoon, but if we use this broaching machine, then at most two people can pull out one barrel in the middle of the afternoon. I am sure of this. !"

"Haha, what are you still doing? Now that you understand the principle of improvement, please calculate and experiment quickly! We don’t lack barrels. You can cast it as you want. We don’t need wood, we don’t need wood. Carpenters, let’s do more. No shortage, so hurry up and experiment! Well, if you can experiment with this improved wooden broaching machine, we can even consider using steel to cast such a broaching machine in the future!"

   Ishikuma's words made Ferguson's eyes light up again...
