[0063] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0064] like Figures 1 to 4 As shown, the embodiment of the present application provides a hard tube hot pressing flanging device 100, the hard tube hot pressing flanging device 100 includes a bottom plate 10, and a bottom plate 10 on the top edge of the bottom plate 10 as shown in FIG. Figure 1 The hard tube heating and shaping device 20 and the linear slide rail 71 are arranged in the first linear direction shown in the figure. The linear slide rail 71 is slidably connected with a movable base 60, and the movable base 60 can move along the first linear direction on the linear slide rail 71. Specifically, the linear slide rail 71 can be provided with a slider 72 that is slidably connected and fixed along its extension direction. The bottom of the movable base 60 is fixedly installed on the top of the slider 72. The extension direction of the linear slide rail 71 is the aforementioned first linear direction; and the movable base 60 is fixedly connected with a hard tube fixing device 50, and the hard tube fixing device 50 includes a tubular through groove 51 that allows the hard tube to pass through. The tubular through groove 51 is fixedly connected to the movable base 60. 1 is also arranged along the first straight line direction; the aforementioned hard tube heating and shaping device 20 includes a heating handle 22 and a heating shaping head 21 which are sequentially arranged along the first straight line direction, and the heating shaping head 21 is opposite to the tubular through groove 51 and arranged along the same axis; a limiting block 40 is also arranged between the hard tube heating and shaping device 20 and the hard tube fixing device 50, and the limiting block 40 is movably connected to the aforementioned movable base 60, and there is a gap between the limiting block 40 and the first notch 511 at one end of the tubular through groove 51 facing the limiting block 40, and the limiting block 40 can form a block or release the block between the hard tube heating and shaping device 20 and the first notch 511.

[0065] Specifically, the aforementioned limit block 40 can be rotatably connected to the mobile base 60 by means of a screw 41, and blocking or unblocking is achieved by rotation. Depending on the size of the selected limit block 40, the installation method, etc., the limit block 40 can be directly set on the base plate 10, can also be set on the mobile base 60, and can also be set on the hard pipe fixing device 50. If it is directly set on the base plate 10, the limit block 40 can be rotatably connected to the base plate 10 at one end, and the other end can be rotated to the required position in front of the first notch 511 with the fixed end as the center. The same is true for being set on the mobile base 60 or the hard pipe fixing device 50. When the limit block 40 is directly set on the base plate 10, a corresponding limit block installation groove can also be set between the hard pipe heating and shaping device 20 on the base plate 10 and the hard pipe fixing device 50, and the limit block is installed by plugging. The function of the limit block 40 is to limit the length of the hard pipe extending from the first notch 511, and the limit block 40 is removed after the hard pipe is fixed.

[0066] Compared with the prior art, the hard tube hot pressing and flanging equipment 100 provided in the embodiment of the present application is provided with a limit block 40 to block or unblock the front of the first slot 511. When blocking, the limit block 40 can ensure that the extension length of the hard tube passing through the tubular through slot 51 is consistent, and then the hard tube is fixed by the hard tube fixing device 50, so that the subsequent hard tube flanging consistency is better; after unblocking, the limit block 40 does not affect the hard tube fixing device 50, which moves on the linear slide rail 71 towards the direction close to the hard tube heating and shaping device 20 under the drive of the movable base 60 to perform hard tube heating and shaping operations, and the processing efficiency is high; at the same time, the linear slide rail 71 is set to first limit the direction and position, which is convenient for the subsequent quick and accurate installation of components, saving time and improving installation efficiency.

[0067] A preferred embodiment is as follows Figure 1 and Figure 4 As shown, there is an adjustable distance interval between the aforementioned limit block 40 and the first notch 511 of the tubular through groove 51 of the aforementioned hard pipe fixing device 50, so that the distance of the interval can be adjusted accordingly according to the specific size of the flange required for the hard pipe to meet the user's requirements for different flange sizes of the hard pipe.

[0068] In the aforementioned embodiment, the aforementioned stopper 40 can be rotatably connected to the movable base 60 by means of the screw 41, and the distance between the stopper 40 and the first notch 511 of the aforementioned tubular through groove 51 can be adjusted by means of the extended length of the screw 41 and / or the thickness and / or number of the stopper 40 sleeved on the screw 41. This implementation scheme is simple in structure, easy to implement, highly reliable, and has good effects.

[0069] A specific embodiment is as follows Figures 1 to 4As shown, the aforementioned hard pipe fixing device 50 also includes a guide column 52, an upper pressing plate 53 and a lower pressing plate 54 arranged opposite to each other, a clamping and fixing switch, and a fixing plate 56 for fixing the clamping and fixing switch; the clamping and fixing switch can be specifically set as a quick clamp 55 to achieve quick clamping and quick positioning, with a small volume and easy installation and use; the guide column 52 can be set as one or more, and the guide column 52 and the fixing plate 56 are both vertically arranged and fixedly connected to the aforementioned mobile base 60; the upper pressing plate 53 and the lower pressing plate 54 is sleeved in the guide column 52, specifically the upper pressure plate 53 can be sleeved in the guide column 52 through the bearing 521, and can move up and down along the guide column 52; the bottom surface of the lower pressure plate 54 can be fixedly connected to the top surface of the movable base 60; and, the upper and lower pressure plates 53 and 54 have opposite surfaces respectively recessed with an upper through groove 531 and a lower through groove 541 extending along the aforementioned first straight line direction and passing through, the upper through groove 531 and the lower through groove 541 are aligned up and down and can be buckled up and down to form the aforementioned tubular through groove 51. The clamping and fixing switch is located above the upper pressing plate 53, and is used for pressing the upper pressing plate 53 downward so that the upper pressing plate 53 and the lower pressing plate 54 are pressed and tightened; specifically, the clamping and fixing switch is a quick clamp 55, and the quick clamp 55 includes a quick clamp mounting plate, a switch component that can be moved up and down and is fixedly connected to the quick clamp mounting plate, and the switch component is linked to a fixed shaft, and the fixed shaft can move up and down under the drive of the switch component; when the switch component is toggled upward to drive the fixed shaft to move upward, the upper pressing plate 53 and the lower pressing plate 54 are in a non-clamping state, and when the switch component is toggled downward to drive the fixed shaft to move downward, and the lower end of the fixed shaft is abutted against the upper pressing plate 53, the upper pressing plate 53 and the lower pressing plate 54 are in a clamping state. By clamping and fixing the switch and setting the upper pressure plate 53 and the lower pressure plate 54, the hard tube to be processed can be limited and fixed quickly, and the planes opposite to each other of the upper pressure plate 53 and the lower pressure plate 54 can be used as flanging pieces. In this way, fewer parts are set up and the structure is more compact, which solves the problem that the existing flanging processing technology is relatively complicated to implement.

[0070] Furthermore, the lower through groove 541 may be provided with concave avoidance grooves 542 on opposite sides along a direction perpendicular to the first straight line direction, and the concave depth of the avoidance grooves is less than the maximum concave depth of the lower through groove 541. The avoidance groove 542 is provided to facilitate the removal of the tube. Preferably, an EAV foam is provided in the avoidance groove 542, and the top surface of the EAV foam is lower than or flush with the upper edge of the avoidance groove 542. The EAV foam for increasing friction is provided in the avoidance groove 542, which can prevent the hard tube placed in the tubular through groove 51 from moving forward and backward, shrinking, etc. when it is not pressed tightly.

[0071] Another preferred embodiment is as follows Figure 1 , Figure 2 and Figure 4As shown, a limit baffle 80 is installed on one side of the linear guide rail 71 close to the heating and shaping head 21 of the hard tube heating and shaping device 20. When the movable base 60 moves to the heating and shaping head 21, the heating and shaping head 21 performs heating and shaping operations on the hard tube until the limit baffle 80 abuts against the movable base 60. The limit baffle 80 locates the position for heating and shaping, and there is no need for the operator to judge the position, which facilitates the quick and accurate arrival at the operating position, further ensures the consistency of processing, and prevents the heating and shaping head 21 from excessively contacting the hard tube fixing device 50 to damage the parts. Preferably, the position of the limit baffle 80 can be adjusted according to the position of the heating and shaping head 21, and specifically, the limit baffle 80 is detachably connected and fixed to the bottom plate 10.

[0072] Furthermore, if Figures 1 to 3 As shown, the hard tube hot pressing flanging equipment 100 provided in the embodiment of the present application may also include a cooling device 30, which is used to facilitate the rapid cooling and leveling of the hard tube after hot melting to ensure the processing effect. The linear guide rail 71 may be provided with downwardly concave positioning grooves 73 on both sides of one end close to the hard tube heating and shaping device 20, and the bottom of the cooling device 30 can be engaged in the positioning groove 73. The cooling device 30 can be movably fixed in the positioning groove 73 by engaging, without fixed connection, and is convenient for taking and putting at any time.

[0073] On the basis of the above-mentioned embodiment, in order to improve the connection stability during operation, the above-mentioned cooling device 30 can be further detachably fixedly connected to the bottom plate 10. Since the cooling device 30 is detachably fixedly connected to the bottom plate 10 and can be movably engaged in the above-mentioned positioning groove 73, when the hot-pressing and flanging work of the hard tube is first performed, the cooling device 30 is not used first, and the mobile base 60 is returned to the original position after the hard tube flanging work is completed, and then the cooling device 30 is engaged in the positioning groove 73, and then the mobile base 60 is directly moved toward the cooling device 30 until the hard tube that has just been hot-pressed and flanging is in contact with the cooling device 30, so as to perform cooling work; the cooling device 30 quickly cools down and flattens the hard tube after hot-melting, further improves processing efficiency, and further ensures processing quality.

[0074] In addition, in order to position the hard tube for quick and accurate installation, the aforementioned hard tube heating and shaping device 20 may also be provided with a positioning member for positioning the heating and shaping head 21 and the heating handle 22, and the positioning member may be fixedly mounted on the bottom plate 10, and specifically the positioning member may include a heating head positioning member 231 for positioning the heating and shaping head 21 and a heating handle positioning member 232 for positioning the heating handle 22. Figure 2As shown, in order to further facilitate installation, the heating head positioning member 231 and the heating handle positioning member 232 can be set as an upper and lower split structure, and the opposite surfaces of the upper split and the lower split can be respectively provided with an upper concave groove and a lower groove, the upper groove and the lower groove are aligned up and down and can be buckled up and down to form an integral groove, and the integral groove is used to fix the heating and shaping head 21 and the heating handle 22 respectively. The lower split is fixedly installed on the base plate 10. After placing the heating and shaping head 21 and the heating handle 22, the upper split is buckled to achieve fixed installation of the hard tube heating and shaping device 20.

[0075] Based on the aforementioned hard tube hot pressing and flanging equipment, its working process can be as follows:

[0076] Step 1, the hard tube heating and shaping device 20 is connected to an AC220V power supply, turned on, and the temperature of the heating and shaping head 21 is set to a suitable temperature;

[0077] Step 2, open the quick clamp 55 upwards, place the hard tube to be processed between the upper pressing plate 53 and the lower pressing plate 54 so that it extends from the first notch toward the heating shaping head 21 in the first direction, manually rotate the limit block 40 to put it in a blocking state, so that the head of the hard tube to be processed presses against the limit block 40 to limit the length of the hard tube extending from the first notch, press the quick clamp 55 downwards to a tightened state, and then rotate the limit block 40 to put it in an unblocked state;

[0078] Step 3, the movable base 60 is pushed along the first straight line direction toward the heating shaping head 21 until the limit baffle 80 abuts against it and the hard tube is melted and deformed;

[0079] Step 4, push the movable base 60 away from the heating shaping head 21 along the first straight line direction to make way for the positioning groove 73, then engage the cooling device 30 in the positioning groove 73, and then push the movable base 60 towards the cooling device 30, press and stand for a few seconds, and push the movable base 60 away after the hard tube is flanging and cooled, and then take out the cooling device 30;

[0080] Step 5, open the quick clamp 55, move the upper pressing plate 53 upward along the guide column 52, take out the processed hard tube to complete the flanging operation.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
