It should be noted that, for the suspension of the knife cover 4, if the knife cover 4 is changed from a lying state to a standing state, the cutting fluid in the receiving groove 43 will flow out from the opening of the receiving groove 43, in order to solve the above problem, it is necessary to design a scheme that a guide plate 431 is arranged in the receiving groove 43, and the guide plate 431 is respectively fixedly connected with four inner side walls of the receiving groove 43, and simultaneously the guide plate 431 is relatively sealed with the inner side walls of the receiving groove 43; the guide plate 431 is obliquely arranged, and one side, close to the flow guide channel 44, of the guide plate 431 is higher than the other side; an overflow port 432 is formed in one side of the guide plate 431, which is far away from the flow guide channel 44, the design of the overflow port 432 enables the cutting fluid in the containing groove 43 to only pass through the overflow port 432 when being discharged from the opening of the containing groove 43, and when the knife cover 4 lies flat, the cutting fluid can slide down along the guide plate 431 and pass through the overflow port 432; when the knife cover 4 is erected, the guide plate 431 is arranged, so long as the volume of the cutting fluid is slightly smaller than the volume between the guide plate 431 and the inner bottom wall of the containing groove 43, the cutting fluid cannot pass through the overflow port 432, and therefore, the guide plate 431 plays a role of guiding the cutting fluid when the knife cover 4 is laid down, and plays a role of blocking the cutting fluid from being discharged from the opening of the containing groove 43 when the knife cover 4 is erected.
In order to continuously add the cutting fluid into the fluid storage cavity 21 during cutting, the cutter cover 4 is further provided with a fluid inlet 49, the fluid inlet 49 is positioned below the joint of the guide plate 431 and the inner side wall of the containing groove 43, a one-way valve is arranged at the fluid inlet 49, so that the cutting fluid can be introduced into the containing groove 43 from the outside, and the cutting fluid in the containing groove 43 cannot be discharged through the fluid inlet 49; after hanging the blade guard 4, let in the cutting fluid to inlet 49 department, the cutting fluid enters into through inlet 49 and connects the groove 43 greatly in, and rethread water conservancy diversion passageway 44 and inlet channel 23 enter into stock solution chamber 21 in, and then guarantee the supply of cutting fluid when cutter 3 cuts, through such mode simultaneously, need not additionally count the pipeline and lead to in stock solution chamber 21, whether the problem of cutting is influenced to the pipeline also need not considered simultaneously, and design cost is lower, has also simplified production technology greatly.
It should be noted that, only when the designated radius is cut, that is, after the cutter cover 4 is suspended, the cutting radius when the cutter cover 4 abuts against the inner side wall of the limiting groove 171 can the ejector block 26 keep the state of pushing the blocking block 46, and when the cutting is performed with the rest radius, a gap exists between the cutter cover 4 and the short side wall of the limiting groove 171, a plug block (not shown in the figure) needs to be used to plug the gap, at this time, the cutter cover 4 can abut against the plug block (not shown in the figure), the ejector block 26 can push the blocking block 46, and further, the cutting fluid can be continuously introduced when the cutting is performed with any radius.
In this embodiment, the position of the overflow port 432 is at the contact position of the guide plate 431 and the receiving groove 43, that is, a gap is formed between the overflow port 432 and the inner side wall of the receiving groove 43, and the guide plate 431 at this section can play a role of preventing the cutting fluid entering from the fluid inlet 49 from spilling, so that the probability that the cutting fluid entering the receiving groove 43 directly passes through the overflow port 432 is reduced.
In order to facilitate the cutting fluid to flow from the fluid inlet 49 to the inner bottom wall of the receiving groove 43, a slope 433 is provided, and one side of the slope 433 close to the flow guide channel 44 is lower than one side close to the fluid inlet 49; the joint of the slope 433 and the inner side wall of the containing groove 43 is lower than the liquid inlet 49; the cutting fluid passing through the overflow port 432 can slide along the slope 433 toward the guide channel 44, and the cutting fluid passing through the fluid inlet 49 into the receiving groove 43 can also slide along the slope 433 toward the guide channel 44.
Due to the design that the slope 433 and the guide plate 431 are arranged simultaneously, the distance between the slope 433 and the guide plate 431 is gradually reduced from one side of the flow guide channel 44 to one side of the liquid inlet 49, when the knife cover 4 is hung, most of cutting liquid in the containing groove 43 is located at one side close to the flow guide channel 44, and the cutting liquid can conveniently flow out of the flow guide channel 44 under the action of gravity because the knife cover 4 is erected.
It should be noted that, if the liquid outlet channel 22 is always in an open state, the cutting fluid in the liquid storage cavity 21 is also discharged when the cutting is not performed, so that the cutting fluid is wasted, in order to solve the above problem, a solution storage sleeve 27 is required to be designed, wherein the liquid storage sleeve 27 is rotatably connected in the liquid storage cavity 21, the liquid storage sleeve 27 is a structure with an open upper end and a closed lower end, the liquid inlet channel 23 is located above the liquid storage sleeve 27, and the liquid storage sleeve 27 is suitable for storing the cutting fluid, that is, the cutting fluid passing through the liquid inlet channel 23 is just stored in the liquid storage sleeve 27; in order to discharge the cutting fluid in the fluid storage sleeve 27 through the fluid outlet channel 22, a through hole 271 is formed at the bottom of the side wall of the fluid storage sleeve 27, and the height of the through hole 271 is equal to the height of the opening of the fluid outlet channel 22 at one side of the fluid storage cavity 21; when the liquid storage sleeve 27 is rotated until the through hole 271 is communicated with the liquid outlet channel 22, the liquid outlet channel 22 is in an open state; when the through hole 271 does not correspond to the liquid outlet channel 22, the liquid outlet channel 22 is in a closed state.
