Description

Technical Field

[0001] This utility model relates to the field of pipe end processing technology, and in particular to an integrated mold for pipe end flaring and flattening. Background Technology

[0002] Pipe flaring refers to enlarging the end of a pipe to a certain diameter as needed, while pipe flattening refers to flattening the end of a pipe. The flared or flattened pipes are then used in conjunction with other pipes to be applied to various specific usage scenarios.

[0003] Currently, conventional pipe flaring equipment typically uses a hydraulic rod to press the flaring head into the pipe when flaring pipes. However, different applications require the pipe opening to be flared to different diameters. Conventional flaring heads are relatively fixed and difficult to adapt to different processing needs. In addition, when flattening the pipe opening, the other end of the pipe will bend up, causing the flattened part to be skewed, which in turn will lead to errors in the flattened pipe opening.

[0004] Therefore, those skilled in the art have provided an integrated mold for flaring and flattening pipe openings to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an integrated mold for flaring and flattening pipe ends. Through a fixed mechanism, the pipe can be fixed on the mold, thereby preventing displacement during the flattening process and avoiding errors. Furthermore, through a replacement mechanism, the flared head can be quickly replaced, thus producing flared pipe ends of different diameters, which improves the practicality of the device to a certain extent.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A tube flaring and flattening integrated mold includes a base, a top plate and a placement groove. The placement groove is provided on the upper surface of the base. A fixing mechanism is provided inside the base. A replacement mechanism is provided on one side of the outer wall of the base.

[0008] The fixing mechanism includes a stamping cylinder, which passes through the top plate and has a fixed plate connected to its output end. A flattening block is connected to the bottom end of the fixed plate, and a fixed frame is slidably connected to the outer wall of the flattening block. Springs are connected to both sides of the upper end face of the fixed frame, and one end of each spring is connected to the bottom end of the fixed plate. Two first bidirectional threaded rods are provided inside the base. A first slider is threaded to the outer wall of both ends of the two first bidirectional threaded rods. A strap is connected between the upper end faces of the two first sliders. One end of one of the first bidirectional threaded rods is connected to a first motor.

[0009] The above technical solution, through the setting of a fixing mechanism, can fix the pipe on the mold, thereby preventing displacement during the flattening process and avoiding errors.

[0010] Furthermore, the replacement mechanism includes a fixed frame, a second motor is disposed inside the outer wall of one side of the fixed frame, a threaded rod is connected to the output end of the second motor, a second slider is threadedly connected to the outer wall of the threaded rod, a hydraulic rod is connected to one side of the outer wall of the second slider, a fixed block is connected to the output end of the hydraulic rod, a third motor is disposed on the outer wall of the fixed block, a second bidirectional threaded rod is connected to the output end of the third motor, a third slider is threadedly connected to both ends of the second bidirectional threaded rod, a connecting rod is connected to one side of the outer wall of each of the two third sliders, and a flared block is engaged with one end of each of the two connecting rods;

[0011] The above technical solution, through the set replacement mechanism, allows for the quick replacement of the flared head, thereby producing flared pipes of different diameters, which improves the practicality of the device to a certain extent.

[0012] Furthermore, each of the two first bidirectional threaded rods has a drive wheel fitted at one end, and a belt connects the two drive wheels;

[0013] The above technical solution enables the two first bidirectional threaded rods to rotate synchronously, thereby fixing the pipe in place with the straps.

[0014] Furthermore, multiple support columns are connected between the top plate and the base. Limiting grooves are formed on one side of the outer wall of two support columns on one side. Limiting blocks are connected to both sides of the outer wall of the fixing plate. The limiting grooves and the limiting blocks are slidably connected.

[0015] The above technical solution enables the flattened block to move vertically up and down.

[0016] Furthermore, the fixing frame and the base are rotatably connected, and a slot is provided on one side of the upper surface of the top plate, and the slot and the hydraulic rod cooperate with each other;

[0017] The above technical solution makes it easy to fold up the mounting frame, which can reduce the space occupied by the device to a certain extent.

[0018] Furthermore, a flattening groove is provided on one side of the upper end face of the base, and the flattening groove and the flattening block cooperate with each other;

[0019] The above technical solution enables the flattening block to flatten the pipe opening inside the flattening groove.

[0020] Furthermore, a locking block is provided on one side of the outer wall of the support column, and the other end of the locking block is connected to one side of the outer wall of the fixing frame;

[0021] The above technical solution secures the mounting bracket in place.

[0022] Furthermore, a controller is provided on one side of the outer wall of the support column, and the controller is electrically connected to the stamping cylinder, the first motor, the hydraulic rod, the second motor and the third motor.

[0023] The above technical solution facilitates the control of various electrical components inside the device and makes operation convenient.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model proposes an integrated mold for flaring and flattening pipe ends. When flattening a pipe end, the pipe is placed inside a placement groove using straps. A controller then controls a first motor to drive a first bidirectional threaded rod to rotate. Simultaneously, because two transmission wheels connected at one end of the two first bidirectional threaded rods by belts allow the two first bidirectional threaded rods to rotate synchronously, thereby fixing the pipe inside the placement groove with two straps to prevent it from lifting during flattening. This improves the accuracy of the flattening process. After fixing, the controller controls a stamping cylinder to move a fixing plate downwards. When it reaches the upper end of the flattening groove, the width of the fixing frame is greater than the width of the flattening groove, causing the spring to contract and the flattening block to continue moving downwards, flattening the pipe end. The spring and fixing frame improve the stability of the flattening process. The fixing mechanism secures the pipe to the mold, preventing displacement during flattening and avoiding errors.

[0026] 2. This utility model proposes an integrated mold for flaring and flattening pipe openings. When flaring pipe openings, first open the locking block, flatten the fixing frame, and then, according to the required flaring diameter, control the third motor via the controller to drive the second bidirectional threaded rod to rotate, causing the third slider to move to both sides, thereby disengaging the connecting rod and the flaring block from the locking state, thus removing the flaring block. Then, reverse the operation to replace it with the required flaring block. After replacement, control the second motor via the controller to drive the threaded rod to rotate, causing the second slider to move up and down, aligning the flaring block with the center of the pipe opening. Then, control the hydraulic rod via the controller to squeeze the flaring block into the pipe opening, thus flaring the pipe opening. Through the set replacement mechanism, the flaring head can be quickly replaced, thereby processing flared pipe openings of different diameters, which improves the practicality of the device to a certain extent.

[0038] Working principle: When flattening the pipe opening, the pipe is placed inside the placement groove 10 using straps 102. The controller 7 then controls the first motor 103 to rotate the first bidirectional threaded rod 104. Simultaneously, because one end of each of the two first bidirectional threaded rods 104 is connected to two transmission wheels 13 via belts 12, the two first bidirectional threaded rods 104 rotate synchronously, thus fixing the pipe inside the placement groove 10 with straps 102. The controller 7 then controls the pressing cylinder 101 to move the fixing plate 107 downwards. When it reaches the upper end of the flattening groove 106, the width of the fixing frame 109 is greater than the width of the flattening groove 106, causing the spring 110 to contract, allowing the flattening block 108 to continue moving downwards, pressing the pipe opening. When flaring the pipe opening, first open the locking block 8 and lay the fixing bracket 201 flat. Then, according to the required flaring diameter, control the third motor 207 through the controller 7 to drive the second bidirectional threaded rod 208 to rotate, causing the third slider 209 to move to both sides, thereby disengaging the connecting rod 210 and the flaring block 211 from the locking state, thus removing the flaring block 211. Then, reverse the operation and replace it with the required flaring block 211. After replacement, control the second motor 203 through the controller 7 to drive the threaded rod 204 to rotate, thereby causing the second slider 205 to move up and down, so that the flaring block 211 is aligned with the center of the pipe opening. Then, control the hydraulic rod 202 through the controller 7 to squeeze the flaring block 211 into the inside of the pipe opening, thus flaring the pipe opening.
