Description of the invention (1) (please read the notes on the back before filling in this page) Everyone knows that, for example, in order to make a coupling device with rigid tubular end pieces, the outer and inner sides of the hose can be coaxial Assemble, sandwiching the free end of the flexible hose between the ring and the rigid tubular element. In order to achieve this, a swaging method is required to reduce the diameter of the ring. Generally speaking, the present invention relates to a method of swaging a ring that engages on the free end of a flexible hose, and the flexible hose itself is gnawed in one ... ... '' .. one one 丨 丨 丨 丨 丨-one-^ g rigid tube to the top of the piece, at least a part of the ring is spun so that its diameter initial value is greater than the diameter of the hose. This method uses a swaging die with an axial die cavity, which includes a flared length extending from the first end to the second end, the die cavity has a large open end, and the diameter of the die cavity is at the second end The location will be roughly equal to the diameter of the bell mouth length. Axial rotary forging is usually used for the odd manufacturing of rigid pipes. In the US Patent No. 2,314,002 approved, Cao tried to use the axial swaging method to swivel the ring engaged on the free end of the flexible hose. Du Yinjie, Employee Consumer Cooperation of the Central Bureau of Economic Affairs of the Ministry of Economic Affairs In this method, the twisted wedge was tied to the eyebrows in the first season. Due to the need to place the swaged forged chess around the hose, Zhongyinong 51 has the most and supervised JiuUi. Because the ring itself is installed on the circumference of the hose, its inner diameter cannot be smaller than the outer diameter of the hose. Because Ji only complies with JI in jt year, the diameter of the animal is reduced. The small set will never be greater than the Yanli H1. As a result, the diameter of Xiaoxiao risked that the size of the hose, ring and tubular paper could not be applied to the Chinese National Standard (CNS) A4 specification (210X 297 mm). The BM7 was printed by the Consumer Labor Cooperative of the Central Standard Falcon Bureau of the Ministry of Economic Affairs. Fifth, the description of the invention (2) The risk of the components being firmly assembled together. The only way to increase the swaging width, even if the diameter is reduced greatly, is to increase the thickness of the ring, but it will inevitably lead to an increase in material cost, M and the energy required for swaging. It is also known that radial swaging can be carried out by moving most of the angle-shaped sectors relative to each other. This method is unsatisfactory because it may cause defects in the appearance of the swaged part, and the vertical gap between the angular sectors can catch longitudinal wrinkles. Such defects can penetrate into the hose and cause damage. The invention attempts to correct these shortcomings. If the swage forging die is placed in this way, at least the larger end of the chess cavity is located around the swaged part, and the first end of the flared length of the cavity exceeds the front end of the hose and is placed in front of the free end , To achieve the goal in this way; when one of the elements composed of the ring and the swaging casting mold is fixed axially, the two elements are moved relative to each other in the backward direction (F>), from The free end referred to as the “front end” of the hose moves toward the other end referred to as the “rear end.” With these configurations, the swaging method is not limited to the thickness of the cut circle. In addition, due to the hose material when swaging is performed (Commonly composed of rubber) The reaction exhibited, by moving backwards, can considerably change the mechanical strength of the fitting consisting of the hose ring M and the tubular element. The hose material is somewhat satin Being pushed, that is, the material undergoes a latent change, and is pushed toward the displacement direction of the satin cast wedge for the hose. The displacement of the piano wants to accumulate to the tmig end of the pushed pipe. (CNS) A4 regulation (2 丨 OX297mm) ^ (-install „Order ^ / (please read the precautions on the back and then fill out this page) A7 B7 305733 5. Description of the invention (3), when you prefer to eat in the curved room, surface material Man Zuzu 1 side ja and sundial, so that the whole creeps backwards, that is to say, it occurs in the opposite direction of the displacement of the rotary satin mold relative to the ring. The flexible hose that happened to be split by the rubber material, Its thick plug JMUg_gL _ is large and can be used as a manufacturing parameter, so the tolerance range can be more than about 1 aa. Due to the local change in thickness, the volume of excess material, that is, the material pushed up locally by the creep " The change is also quite large. Therefore, the pressure of the material of the hose inside the ring is subject to very large local changes. To make the ring able to withstand such changes without deformation, M and to ensure the joint between the hose ring and the tubular element In addition, when the displacement towards the free end of the hose occurs, the material of the hose is subject to both creep and strong pressure changes at the same time, which affects its mechanical properties. According to the invention, the displacement is backward, during swaging Time effect The pressure at the free end of the hose is continuously distributed over the entire circumference, so the hose will not be crushed or crushed suddenly. Since the free end of the hose is gradually swaged toward the axis, the hose The composition material is subject to gradual creep, which will not damage the softness, especially M can maintain the quality of the accessories that it needs to be closed. The swaging is therefore carried out regularly and gradually * making the ring and hose firm -------- ----------------.......... II ............................ .. II 1.11 .. ».

Description of the invention (4) braved Danger of damage to hoses: To ensure the reliability and durability of coupling devices, they are subjected to increasing peg endurance tests, one of which is to make the hose oscillate to the ring: the rear part of the ring An open matter makes it possible to avoid hose wave damage or cut when performing this test-the invention will be fully understood and its celebration will appear when reading the examples detailed below. Explanation Shito see the attached figure, in which: Figure 1 is a longitudinal cross-sectional view showing a ring connected to the free end of a flexible hose, the flexible hose itself is connected to A rigid tubular element, and the figure also shows a swaging casting mold, and the first implementation of the method of the present invention can be carried out by using the casting mold; Figures 2 and 3 respectively show the method of the present invention. Start And at the end; Figure 4 is one of the similar figures in Figure 1, which will be applied to the implementation of a different aspect of the present invention; and Figure 5 shows the implementation of the method · Figure 1 shows the The free end l〇a is engaged with the flexible tube τπ 12 flexible hose K), and the cylindrical ring 14 is engaged with the free end l〇a --F-- back to 0 to simplify the following description Assuming that the 10a end is the front end of the flexible hose, because the garden shape is deleted, so the distal end or the rear end is not shown. In the first figure, the ring 1 4 'before swaging is shown. The diameter D is larger than the diameter of the hose 10. The first drawing also shows a swaging die with an axial die cavity 18. The die cavity has a bell mouth length 18 a, a diameter i from the first end 19 a and a diameter d of the first --- ----_ 装 ------ 訂 ----- (Line (please read the precautions on the back before filling in this page) A7 B7 printed by the Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (5) The two ends 19b expand outward, the diameter d is greater than the diameter D, and the diameter D itself is greater than the diameter d '. Immediately adjacent to the first end 19a of the length of the bell mouth, the chess hole contains a circular cylindrical length 18b * The outside flares to a narrow open end 17. At the other end, the wedge has a large open end, as shown in the example, which corresponds to the second end 19b of the truncated conical length of the truncated cone.圔 shows the elements before the start of the swaging process, in which the axis of the die cavity is in line with the longitudinal axis A of the flexible hose, and the large open end 20 is toward the back. Figure 1 also shows the axial direction The tool 22 that fixes the ring 14 engages the rear end 14b of the urn ring. The tool is only shown in Figure 1, which may contain two jaws. This way around the hose, and the ring ring The free end of 14 is the same, so as to confirm the position during the swaging. To start the swaging process, place the swaging forge in such a way that at least the larger end 20 of the die cavity is located around the ring to be swaged , And the first end 19a is placed in front, beyond the front end of the hose, in other words, the cast wedge moves relative to the swaging ring in the direction of the arrow F, that is, from the front end of the hose toward its The rear end, or until the end 20 of the wedge contacts the front end 14a of the ring. When the opening of the inside of the chess hole coincides with the foreign circumference of the ring, the forging is just right. If you want to perform forging, as in the second As shown in Fig. 3, the rotary satin cast wedge 16 moves axially to the ring 14 in the direction of the arrow P, that is, backward. It can be understood that when this displacement occurs, the cutter 22 is fixed due to the ring It is fixed in an appropriate position, so its external diameter gradually decreases to the size of the chessboard paper. The Chinese national standard (CNS) A4 specification (210X297mm) is applied (read the precautions on the back and then fill in the Qiaoben I). Order * 8 The ministry of economics of the Central Bureau of Economic Affairs of the Ministry of Economic Affairs printed the A7 B7 18 Diameter d '. When this happens, the creep is gradually acting on the end of the flexible hose loa. At the end of the swaging, it reaches the shape shown in Picture 3, where the urn ring is folded in The end of the hose is above loa, and the hose is firmly clamped between the rigid tubular element 12 and the ring 14. As seen in this figure, it shows the end of the swage. The thin wedge 16 is opposite The axial displacement of the ring 14 is preferably stopped at the smaller diameter end of the bell mouth length 18a of the mold cavity before reaching the rear end 14b of the ring 14 away from the free end 10a of the hose 10. The rear end of the ring As a result, the portions are slightly withdrawn and spread out, without risking damage to the hose. In addition, it can be seen from the figure that the tubular element 12 has a radial protrusion dS 13 near its rear end.

When the binding wedge moves in the direction of the arrow F • After the two wedges are close to each other by the ring, the axial swaging just starts, and the channel is eliminated. Once the two wedge shells M are assembled together in this way, the cavity of the thin mold is determined, which has a bell mouth length 118aM and a smaller diameter figure column length 118b. The smaller end 121 of the cavity is located away from the opening of the larger end 120, as seen in the fifth garden, which makes it possible to place the mold 116 around the portion 115b to be swaged, and to make the ring 114 first Part 115a is pushed forward beyond the thin die. By moving the die 116 in the direction of arrow F, the part 115b is swaged, that is, by swaging it from the dotted line Move the position to the swaging end position shown by the solid line. During the entire axial displacement of the swaging and casting chess, the ring is fixed axially by the satin cutter. In the example shown in Figures 4 and 5, the cutter 122 is formed by the front end of the ring 114 The consistent paper size applies to China National Standard (CNS) A4 (210X297mm) • l ^ iin ^ i DI HI — ^ ϋ I ^^^ 1 ι ^ ϋ m ί UK —J ··,.

Description of invention (8) The composition of the jaws. More precisely, the jaws of the tool 122 Immediately after the first end portion, it is placed around the ring and is close to the chopstick portion 114 'in order to fix the ring and prevent it from moving backward during swaging. As can be seen in Figure 4, it is located at The diameter of all the second parts 115b after the first part 115a of the ring before swaging is larger than the diameter to be reduced by swaging, this situation is particularly applicable to the first end part 11 5a After that part 115b front end region 115c. As a result, when the wedge shells move towards each other around the ring, the thin mold is pinned Before moving, a preliminary step of radial swaging is performed in this area 115c, and only a small part of this part of the length is swaged. As can be seen in the fourth and fifth figures, it is best to perform the radial swivel This part 115c of the preliminary forging step can be extended forward beyond the front end 110a of the flexible hose, so that any defects formed by performing radial swaging will not affect the hose. It is also possible that the diameter is initially less than or equal to the diameter of the swaging. In this case, no preliminary step of radial swaging is necessary. Although in the example shown in the figure, the ring is fixed axially * and The mold moves in the direction of the arrow P, but I should note that if the cast iron is fixed axially and moves in the opposite direction of the arrow F, the result will be the same, the focus is on the two An element composed of a ring and a bound chess moves along with the wedge in the direction of arrow F, and also moves backward, along the chopstick forging section. The paper moves in pairs with each other.
