Abstract
Description
Technical Field
[0001] The utility model relates to the field of die structures, in particular to a standard flaring die. Background Art
[0002] The existing flaring machine uses a general flaring die. For pipes with an inner diameter of Φ13 - Φ24mm, the same flaring die is used for flaring, and the size of the flaring is controlled by controlling the advancing distance of the flaring die.
[0003] Defects and deficiencies of the prior art:
[0004] The size of the pipe flaring is determined by the length of the flaring die entering the pipe. When flaring pipes of the same length, the end point of the advancement of the flaring die is the same. If the length of the pipe is too long, the distance that the flaring die enters the pipe will be long, and vice versa. Thus, to obtain high - requirement flaring products, the requirement for the length of the pipe needs to be improved.
[0005] The size of the flaring is very sensitive to the length. The finished products and other processes do not have very high requirements for the length tolerance of the pipe. Thus, for the flaring process, it is necessary to improve the length tolerance accuracy of the pipe, which increases the production cost. Content of the Utility Model
[0006] The purpose of the utility model is to provide a standard flaring die. By replacing flaring dies of different sizes and controlling the distance it enters the pipe, precise flaring can be performed, so as to reduce the accuracy requirement for the length tolerance of the pipe and effectively reduce the cost.
[0007] To achieve the above purpose, the utility model provides a standard flaring die. The flaring die includes a flaring die, a fixed seat and a mounting seat. The flaring die is a cone with different radial sizes. The flaring die is fixed on the top surface of the fixed seat. The fixed seat is detachably installed on the mounting seat, and the mounting seat is locked in the flaring mechanism.
[0008] Further, in the standard flaring die, the mounting seat is provided with a protruding locking post, the bottom end of the fixed seat is provided with a locking groove cooperating with the locking post, the outer side of the fixed seat is provided with a locking hole communicating with the locking groove. The fixed seat is inserted and clamped on the locking post and fixed by a lock in the locking hole.
[0009] Further, in the standard flaring die, the locking hole is provided with threads.
[0010] Further, in the standard flaring die, the mounting seat is provided with a locking section.
[0011] Further, in the described standard flaring die, the flaring die is installed in a flaring mechanism, and the flaring mechanism includes a flaring base, a workbench, a support frame, and a flaring oil cylinder. The flaring base is used to fix the pipe. The flaring base is arranged on the workbench. The support frame is arranged under the bottom side of the workbench and below the flaring base. The flaring oil cylinder is fixed on the support frame. A detachable flaring die is arranged at the position where the flaring oil cylinder faces the flaring base. The flaring oil cylinder performs flaring work in the flaring base by controlling the stroke of the flaring die.
[0012] Further, in the described standard flaring die, the cylinder body of the flaring oil cylinder is fixedly connected to the support frame. The extending end of the flaring oil cylinder faces the flaring base, and the flaring die is fixed to the extending end of the flaring oil cylinder.
[0013] Further, in the described standard flaring die, the flaring mechanism further includes a drive controller, which is used to define and set the drive program of the flaring oil cylinder to control the flaring stroke and flaring pressure of the flaring die. The flaring stroke is greater than the required flaring depth.
[0014] Compared with the prior art, the beneficial effects of the present utility model are mainly reflected in: it can effectively solve the problem that the requirement for the length tolerance during the machining of the cylinder barrel has to be improved in order to ensure the flaring accuracy; by directly replacing the flaring dies of different model sizes, the flaring requirements for pipes of different sizes can be achieved; by limiting the flaring stroke of the flaring oil cylinder, the outer diameter of the flaring of different pipe inner diameters during the model change can be ensured, and the debugging time for the model change can be shortened.

[0017] The standard flaring die of the present utility model will be described in more detail below with reference to the schematic diagrams, in which the preferred embodiments of the present utility model are shown. It should be understood that those skilled in the art can modify the present utility model described herein while still achieving the beneficial effects of the present utility model. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation to the present utility model.
[0018] In the present utility model, unless otherwise clearly specified and defined, terms such as "assembly", "connection", and "linkage" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may also be a mechanical connection; it may be a direct connection or a connection through an intermediate medium, and it may be an internal connection between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0019] In the following paragraphs, the present utility model will be described more specifically by way of example with reference to the accompanying drawings. According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the embodiments of the present utility model.
[0020] As Figure 1 shown, the present utility model provides a standard flaring die. The flaring die 1 includes a flaring die 11, a fixed seat 12, and a mounting seat 13. The flaring die 11 is a cone with different radial dimensions. Specifically, the conical part of the original general flaring die is segmented section by section according to requirements. The flaring die 11 is fixed on the top surface of the fixed seat 12. The fixed seat 12 is detachably mounted on the mounting seat 13, and the mounting seat 13 is locked in the flaring mechanism. By directly replacing the fixed seat 12 with a flaring die 11 of different radial dimensions on the mounting seat 13, it can cooperate with pipes 3 of different sizes for flaring, shortening the commissioning time for mold change.
[0021] Furthermore, the mounting seat 13 is provided with protruding locking columns, the bottom end of the fixed seat 12 is provided with locking grooves cooperating with the locking columns, the outside of the fixed seat 12 is provided with locking holes 121 communicating with the locking grooves. The fixed seat 12 is inserted and clamped on the locking columns and fixed by the locks in the locking holes 121, and the locking holes 121 are provided with threads, which can conveniently and effectively disassemble and replace the fixed seat 12 on the mounting seat 13 to replace flaring dies 11 of different sizes.
[0022] Furthermore, as Figure 1 shown, the mounting seat 13 is provided with a locking section 131, which is convenient for the flaring die 1 to be locked in the flaring mechanism through the locking section 131 of the mounting seat 13.
[0023] Furthermore, as Figure 2As shown in the figure, the flaring die 1 is installed in the flaring mechanism. The flaring mechanism includes a flaring base 21, a workbench 22, a support frame 23, a flaring oil cylinder 24, and a drive controller 4. The flaring base 21 is used to fix the pipe 3. The flaring base 21 is arranged on the workbench 22. A support frame 23 is provided on the bottom side of the workbench 22 and is located below the flaring base 21. The flaring oil cylinder 24 is fixed on the support frame 23. A detachable flaring die 1 is provided at the position where the flaring oil cylinder 24 faces the flaring base 21. The drive controller 4 is used to control the flaring oil cylinder 24 to perform a pushing operation. The flaring oil cylinder 24 can stably and reliably provide power for the flaring die 1 to move forward. That is, the flaring oil cylinder 24 performs a flaring operation in the flaring base 21 by controlling the stroke of the flaring die 1. At the same time, the drive controller 4 is used to limit and set the driving program of the flaring oil cylinder 24 to control the flaring stroke and flaring pressure of the flaring die 1. The flaring stroke is greater than the required flaring depth.
[0024] Further, as Figure 2 shown, the cylinder body of the flaring oil cylinder 24 is fixedly connected to the support frame 23. The extending end 25 of the flaring oil cylinder 24 faces the flaring base 21, and a flaring die 1 is fixed to the extending end 25 of the flaring oil cylinder 24, so that the flaring die 1 faces the pipe 3 fixed in the flaring base 21.
[0025] The working principle is as follows:
[0026] Insert and fix the pipe 3 in the flaring base 21 so that the end opening of the pipe 3 faces the flaring die 1. Then, start the flaring oil cylinder 24 through the drive controller 4. The flaring die 1 will gradually approach the pipe 3 and come into contact with the end opening of the pipe 3. The flaring die 1 squeezes the end opening of the pipe 3 under the drive of the flaring oil cylinder 24, thereby completing the flaring of the end of the pipe 3.
[0027] Since the existing flaring operation controls the pushing distance of a general flaring die in the pipe 3 to control the flaring size in pipes 3 of different sizes, this operation has relatively high requirements for the length of the pipe 3. In order to reduce costs, it is necessary to change the flaring control method and change the control of the flaring die stroke to the control of the distance entering the pipe.
[0028] In this application, flaring dies of various specifications are designed according to different pipe inner diameters. That is, the conical part of the original general flaring die is cut into sections as required and respectively installed and fixed on the end faces of the columns of the separate fixing seats 12 to make flaring dies dedicated to different pipe inner diameters.
[0029] At the same time, in order to control the outer diameter of the expansion, the expansion size is limited by the plane at the end of the expansion, and the expansion cylinder 24 is controlled to control two parameters at the same time: one is that the expansion stroke is greater than the expansion depth; the other is to control the expansion pressure of the equipment so that it can reach the expansion force without deforming the pipe when the plane of the expansion mold hits the pipe mouth. Therefore, the drive controller 4 pre-coordinates the expansion cylinder 24 to correspond to pipes 3 of different specifications, sets the corresponding expansion cylinder 24 stroke and expansion pressure, and cooperates with expansion molds of different specifications to perform corresponding expansion operations.
[0030] In addition, since a flaring die of specified specifications is used, the flaring stroke deviation of pipes with different diameters will not exceed 2 mm. Therefore, by simply increasing the stroke of the flaring cylinder 24 by a fixed value, such as 10 mm, the outer diameter of the expanded pipe with different inner diameters can be guaranteed during the change of the mold, which can greatly shorten the debugging time for the change of mold.
[0031] In summary, in this embodiment, the proposed standard expanding die can effectively solve the requirement of increasing the length tolerance during cylinder processing in order to ensure the expanding accuracy; by directly replacing expanding dies of different models and sizes, the expanding requirements of pipes of different sizes can be achieved; by limiting the expanding stroke of the expanding cylinder, the outer diameter of the expanded inner diameter of different pipes can be guaranteed during the change of model, and the debugging time of the change can be shortened.
[0032] The above are only preferred embodiments of the present invention and do not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, may make any equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which shall be deemed as the content of the technical solution of the present invention and still fall within the protection scope of the present invention.
