Abstract
Description
Technical Field
[0001] The present application relates to the field of flat-end equipment technology, and in particular to a flat-end equipment. Background Art
[0002] Flattening equipment is a processing device that trims the end faces of pipe fittings, making them flat and beautiful. During the use of gas pipe fittings, the flatness of the pipe end faces directly determines the stability of the connection structure and the airtightness of the connection between pipe fittings. Therefore, the flatness requirement of the end faces of gas pipe fittings is an important indicator for judging whether the pipe fittings are qualified.
[0003] However, existing flat-end cutting equipment often uses a tool to clamp the end of the pipe and then uses a flat cutting device to cut the end of the pipe. Although this method can achieve the cutting purpose, the repulsive force between the pipe and the cutting device during the cutting process can cause the cutting device to deviate, resulting in an uneven surface after the pipe is cut. Utility Model Content
[0004] In order to improve the situation in the prior art where flat-end cutting equipment for pipe fittings is prone to positional deviation during the process of cutting pipe fittings, resulting in uneven end faces of the pipe fittings after cutting, the present application provides a flat-end equipment.
[0005] The flat-end equipment provided in this application adopts the following technical solution:
[0006] The cam is fixedly mounted on a support frame, and the cam is secured to a location where the cam is secured to a position where the cam is moved along the support line.
[0007] By adopting the above technical solution, in the process of the propulsion plate driving the motor and the flat punch fixedly connected to the motor output shaft to cut the end face of the pipe fitting, since the propulsion plate and the mounting plate are connected by a number of propulsion slide bars, the propulsion plate and the mounting plate can always be kept parallel to each other, so that the flatness of the end face of the pipe fitting after cutting is higher, and the propulsion plate is avoided from tilting during the cutting process, resulting in uneven cutting. The structure is simple and can ensure the stability of the cutting process, and avoid shaking of the equipment and reducing the flatness of the end face of the pipe fitting after cutting.
[0008] Optionally, the clamping mechanism includes a vertical pole fixedly mounted on the mounting plate, a cylinder being mounted on the vertical pole, an arc block for clamping the pipe being fixedly connected to the end of the telescopic rod of the cylinder, and the arc surface of the arc block is consistent in size with the arc surface of the U-shaped groove.
[0009] By adopting the above technical solution, when the equipment is working, the arc block and the U-shaped groove can be completely fitted with the side wall of the pipe fitting, thereby increasing the ability of the pipe fitting to resist impact force during the cutting process, and also avoiding shaking of the pipe fitting, which leads to a decrease in the flatness of the rear end surface after cutting.
[0010] Optionally, a docking block is integrally connected to one side of the mounting plate close to the motor, and a docking groove connected to the U-shaped groove is provided through the docking block along the width direction, and the docking groove includes a slide groove portion connected to the upper side of the docking block and an arc-shaped groove portion flush with the arc surface of the bottom of the U-shaped groove, the slide groove portion is connected to the arc-shaped groove portion, and the arc block slides into the slide groove portion.
[0011] By adopting the above technical solution, the sliding cooperation between the slide groove part and the arc block can limit the arc block, so as to avoid excessive clamping force on the pipe fitting and causing damage to the pipe fitting surface during the process of the arc block and the U-shaped groove jointly clamping the pipe fitting. At the same time, the arc groove part can increase the area of the side wall of the pipe fitting and the clamping mechanism, so as to avoid radial stress inside the pipe fitting during the clamping process, which affects the cutting effect.
[0012] Optionally, the fixing frame includes a fixing plate parallel to the propulsion plate and a plurality of connecting short rods circumferentially fixedly connected between the fixing plate and the propulsion plate, the motor is arranged between the area surrounded by the plurality of connecting short rods, and there is a gap between the plurality of connecting short rods close to the base and the base.
[0013] By adopting the above technical solution, it can be ensured that the motor will not be affected when the pressure pump pushes the propulsion plate. At the same time, the gap between the connecting short rod and the base will also make it easier for the pressure pump to push the propulsion plate and the motor.
[0014] Optionally, a plurality of limiting holes are provided on a side of the propulsion plate close to the motor, and the plurality of limiting holes correspond one-to-one to the propulsion slide rods, and the diameters of the plurality of limiting holes are larger than the diameters of the plurality of propulsion slide rods, and the ends of the plurality of propulsion slide rods close to the propulsion plate are connected to limiting blocks, and the limiting blocks are movably fitted in the limiting holes.
[0015] By adopting the above technical solution, the propulsion plate and the propulsion slide rod can be prevented from separating during the operation of the equipment, thereby ensuring the integrity of the equipment structure.
[0016] Optionally, the width of the position connecting the motor and the plurality of connecting short rods on the propulsion plate is greater than the width of the position connecting the propulsion sliding rod at both ends of the propulsion plate.
[0017] By adopting the above technical solution, the structure of the propulsion plate is reinforced to avoid excessive impact force on the middle part of the propulsion plate during equipment operation, which may cause damage to the propulsion plate.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] 1. This application provides a plurality of push slide bars between the push plate and the mounting plate to limit the push plate laterally, so that the push plate is always parallel to the mounting plate during the operation of the equipment, thereby improving the flatness of the end surface of the cut pipe;
[0020] 2. The present application provides a larger contact area between the pipe fitting and the clamping mechanism by providing a docking block, thereby improving the stability of the pipe fitting during equipment operation and also protecting the side wall of the pipe fitting;
[0021] 3. This application utilizes a pressure pump to push the propulsion plate to slide on the propulsion slide rod, thereby ensuring the smooth operation of the equipment and making it easier for the equipment to accurately cut the pipe fittings. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is combined with Figure 1-2 This application is described in further detail.
[0026] The embodiment of the present application discloses a flat-mouth device.
[0027] Reference Figure 1 A flat-mouth device includes a base 1, a mounting plate 2 integrally mounted on one end of the base 1 along its longitudinal direction, and a push plate 3 slidably mounted on the base 1. The mounting plate 2 and the base 1 are perpendicular to each other, and the push plate 3 and the mounting plate 2 are parallel to each other along the length of the base 1. Four push rods 4 are symmetrically fixed to the side of the mounting plate 2 closest to the base 1. The two push rods 4 on the same side are located in the same vertical plane and are symmetrically fixed to the mounting plate 2 along the vertical direction.
[0028] Reference Figure 1 and Figure 2 Furthermore, the propulsion plate 3 is slidably connected to the plurality of propulsion slides 4, and a structure is provided between the two to prevent the propulsion plate 3 from accidentally separating while sliding on the propulsion slides 4. Specifically, the propulsion plate 3 is provided with a plurality of limiting holes 31 having a diameter larger than that of the propulsion screws, and the plurality of limiting holes 31 are coaxial with the plurality of propulsion screws. The ends of the plurality of propulsion screws away from the mounting plate 2 can be detachably connected to limiting blocks 41, and the plurality of limiting blocks 41 correspond one-to-one with the plurality of limiting holes 31, and the plurality of limiting blocks 41 are movably fitted within the plurality of limiting holes 31 on the side of the propulsion plate 3 away from the mounting plate 2.
[0029] Reference Figure 1 and Figure 2 A fixing bracket 5 is fixedly mounted on the middle portion of the side of the push plate 3 away from the mounting plate 2. A motor 6 for providing power for pipe cutting is housed within the fixing bracket 5. The output shaft of the motor 6 rotates and penetrates the push plate 3. A flat punch 7 is fixedly mounted on the other end extending from the push plate 3. Several flat blades 71 for cutting the pipe are fixedly mounted along the circumference of the flat punch 7 on the side away from the push plate 3.
[0030] A pressure pump is connected to the end of the mounting bracket 5 away from the propulsion plate 3, which is used to push the propulsion plate 3 and the motor 6 connected to the propulsion plate 3 to slide along the axis of the propulsion slide 4. A U-shaped groove 21 is formed through the mounting plate 2 and communicates with the top side of the mounting plate 2. A clamping mechanism 8 for clamping the pipe is provided at the location of the U-shaped groove 21.
[0031] In the structure of the present application, the pressure pump is a driving component and can be replaced by other components with the same function, so it is not shown in the drawings.
[0032] Preferably, the fixing frame 5 includes a fixing plate 51 parallel to the propulsion plate 3 and a plurality of connecting rods 52 circumferentially connected to the fixing plate 51 and the propulsion plate 3 at both ends. The motor 6 is disposed within the area enclosed by the connecting rods 52, with the end of the motor 6 distal from the output shaft fixed to the fixing plate 51. In this application, to ensure sufficient structural stability of the fixing frame 5, preferably there are four connecting rods 52, each disposed near the four corners of the fixing plate 51.
[0033] Preferably, there is a gap between the connecting short rod 52 located below the motor 6 and the base 1, so that the pressure cylinder can push the fixed block to make the propulsion plate 3 slide more conveniently, thereby reducing friction.
[0034] The width of the area on the propulsion plate 3 connecting the motor 6 and the four connecting short rods 52 is greater than the width on both sides of the propulsion plate 3, so that the middle part of the propulsion plate 3 has a higher load-bearing capacity, preventing the propulsion plate 3 from being subjected to excessive local force when the equipment is working, resulting in its breakage.
[0035] Reference Figure 1 and Figure 2 Furthermore, the clamping mechanism 8 includes a vertical rod 81 fixedly provided on the mounting plate 2, and a cylinder 82 fixedly mounted on the vertical rod 81. The telescopic rod of the cylinder 82 is vertically downward, and an arc block 83 is fixedly connected to its end. The arc surface of the arc block 83 is vertically downward, and its axis is on the same vertical line as the axis of the cross section of the U-shaped groove 21 on the same vertical plane. The arc inner surface of the arc block 83 is consistent with the size of the U-shaped groove 21, that is, the radius of the two is the same, so that when the clamping mechanism 8 clamps the pipe fitting, the inner wall of the U-shaped groove 21 and the inner surface of the arc block 83 can be in close contact with the side wall of the pipe fitting to prevent the pipe fitting from vibrating and displacing.
[0036] Reference Figure 1 and Figure 2 Furthermore, a docking block 9 is integrally connected to the mounting plate 2 on the side near the motor 6, and a docking groove 91 is formed through the docking block 9 and communicates with the top of the docking block 9. The docking groove 91 includes a chute portion 911 and an arcuate groove portion 912 that communicate with each other. The chute portion 911 slides with the arcuate block 83, and the arcuate groove portion 912 is flush with and of equal size to the arcuate surface at the bottom of the U-shaped groove 21. This design structure can increase the contact area between the pipe and the clamping mechanism, making the pipe more stable during cutting, less prone to displacement and shaking, and improving the flatness of the end face of the cut pipe.
[0037] The implementation principle of a flat-mouth device in the embodiment of the present application is as follows:
[0038] After a worker places a pipe into the U-shaped groove 21, the cylinder 82 drives the curved block 83 downward, clamping the pipe. At this point, the pressure cylinder pushes the fixed plate 51 and the push plate 3, which is connected to the fixed plate 51 via the connecting rod 52, along the push slide 4, causing the flat punch 7 connected to the motor 6 to abut the end of the pipe. The motor 6 is then turned on, and the flat punch 7 begins to rotate. The flat blade 71 on the flat punch 7 and the pressure cylinder then work together to flatten the end of the pipe.
[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
