MZ4 / J24 V. Creation instructions (1) < The new type of creation is a kind of material that can be made from the spring of the material to be cut to prevent the rotation < previous technique sees the sharp board which is attached to the extension of the machine 4 Rolled staggered milled plates 3 1 are cut, and cut 4 2 are sent outward; 43 rooms have a relatively variable shape knife processing method to master and then the effect of the movement is only 42. After the material 31 is in a state When it ’s serious, the conveyor belt 41 is under pressure. When it is in a non-rotating position in view of the technical field of the custom, it is related to the pressing and feeding structure of the milling machine, especially the cutting and milling feed knife. The front is indeed pressed to avoid the deviation of the dimensional accuracy of the sharp cutting of the plate, and the structure that can effectively guide the plate to rotate when the cutting tool of the plate rotates. As shown in Figures 1 and 1A, the related material pressing device of the machine is provided with a plurality of parallel wheels 42 'across the front and rear ends of the conveyor belt 41, and between the two sets of pressure rollers. Multiple cutters 43 'Using the front pressure roller 42 will be appropriately pressed by the conveyor belt 41 to facilitate the backward feeding of the milling cutter 43 cut = processed plate 31, and then by the rear pressure roller. However, this structure Due to the long distance between each pressing roller 42 and the milling cutter, when the plate 31 itself is distorted, elastic, etc., the second pressing roller 42 is sent out by the pressing roller 42, and it is still warped if it is intended to be entered by the milling cutter 43 In the case of bending, the machining accuracy is not even caused, and the processed workpiece is scrapped. …, The machine 4 is flat on the side of the conveyor belt 41, and any support is provided. The plate 31 is partially clamped in the second stage of the conveyor belt when compared with the pressure between I and the belt 41. 'It is shaped by pressing the roller, so the friction between it and the milling cutter 43 will cause troubles and safety concerns in the board. "The related pressure and feeding mechanism of the reverse machine has the above disadvantages

The purpose of this creation is to provide a pressing and feeding structure for a milling machine, which is mainly provided with a plurality of parallel side-by-side and downwardly extending extension pressing plates at least at the front end of the conveyor belt, respectively, to the side of the milling cutter, so that each extension The pressing piece is connected to a pressing part with a guide inclined surface extending obliquely at the extended end, and the length of each extended pressing piece is different according to the position of the pressing piece. It can be set to an appropriate arc edge with the edge of each pressing piece. In order to keep the end edge of each pressing part closest to the milling cutter, and each extension pressing piece has an independent elastic device, each extension pressing piece can maintain an elastic pressing force, respectively. The guide slope of the sheet can guide the incoming sheet to the bottom of the pressing part, and each extension sheet is separated and independent of the elastic down force, which can adapt to the different degree of warping and distortion of the sheet to maintain a uniform pressure. The main purpose of the creation is to make the plate cut in the most flat state to avoid affecting the processing accuracy due to the warpage of the end of the plate.

The press and feeding structure of this type of milling machine created according to this book, the machine is provided with an appropriately protruding long side guide bar on the two sides of the conveyor belt, and the side guide bar is used to form the side of the board. Guidance and blocking can prevent the plate to be processed from friction with the milling cutter when it cuts friction with the milling cutter, to avoid the trouble of feeding, which is another purpose of the creation. As for the detailed structure, application principle, function and effect of this creation, you can get a complete understanding with reference to the following description made with reference to the drawings: < embodiment >

Creation instructions (5) The elasticity of the bifurcated portion 2 1 2 towards the upper support plate 23 2 3 3 The force of the elastic downward pressure can be adapted to the uniform pressure, respectively. Short-term use of the conveying and blocking can cause friction when it is processed. After the processing, the second blanking device is transported to the second blanking plate 3, so that it can be adapted from the above, so as to produce friction evenly. At the same time, the industry's availability is only used to limit the equal upturn made by this area, and the elastic element 233 is compressed to incline the long hole 2 3 1 at the upper end of the bolt 232. At the same time, the use of each elastic element can make each elastic The sheet 21 is held in conjunction with the extended pressing sheet 24, respectively. By the separate and independent elastic pressing of each extended pressing sheet 24, the surface shape of the sheet 3 should be warped and twisted and changed to ensure that the sheet 3 is subject to the most flat state. The plate 3 cut by the milling cutter 15 is subjected to the milling cutter by extending the pressing plate 24. 5 During the cutting, the side guide 13 on the side of the belt 11 forms a guide plate 3 on the side of the plate 3 and is milled without other auxiliary pressure. The knife j 5 will not rotate with the sharp knife 15; S is transported backward through the milling belt 11 and can be slid from the guide bevel 242a into the extended pressing piece 24 of the other side 2a under the extended pressing portion 243. The elasticity of the pressing down of the extended pressing piece 24 placed on 2a can be used to resist the cutting. It is sent out by the pressure roller 12 on the other side. It can be known that the cutting machine and the feeding structure of the creation of the board do not have the same degree of warpage and distortion as the plate, but maintain a uniform pressure for cutting. The cutting and milling of the board will not rotate with the rotation of the milling cutter. The effect is indeed productive, novel and progressive. The author is only one of the preferred embodiments of this creation, and the scope of the implementation of the creation. That is to say, all changes and modifications of the patent scope applied for under this creation are covered by the scope of this creation patent. &
