Detailed Implementation

[0038] The present invention will now be described in further detail with reference to the accompanying drawings.

[0039] refer to Figures 1 to 4 A pipe bending device, comprising:

[0040] Clamping and feeding mechanism 1 is used for feeding and clamping the pipe 4; and

[0041] The bending mechanism 3 includes a first bending part 31 and a second bending part 32. The first bending part 31 can perform a left bending action, and the second bending part 32 can perform a right bending action.

[0042] refer to Figure 7The pipe 4 is fed under the drive of the clamping and feeding mechanism 1. When it reaches the preset position, the position of the pipe 4 is fixed. Then, the first bending part 31 of the bending mechanism 3 performs a leftward bending action. Then, the pipe 4 is fed again, and then the second bending part 32 performs a rightward bending action. This process is repeated to produce a serpentine or S-shaped pipe 4. Of course, the bending process can be designed to bend to the left first and then to the right, or to bend to the right first and then to the left. Thus, by setting two bending parts to perform bending actions in two directions respectively, the pipe 4 does not need to rotate 180 degrees between bending actions, improving bending efficiency.

[0043] refer to Figure 3 The first bending part 31 includes a first bending die 312, a first cylinder 311 and a first rotary motor 313. The first cylinder 311 drives the opening and closing of the first bending die 312, and the first rotary motor 313 drives the first bending die 312 to rotate. The first bending die 312 is composed of an upper die and a lower die. The upper die realizes the opening and closing action under the drive of the first cylinder 311. When the pipe 4 is fed to the preset position, the first bending die 312 closes the die to clamp the pipe 4. Then, the first rotary motor 313 rotates to realize the bending action.

[0044] refer to Figure 3 The second bending section 32 includes a second bending die 322, a second cylinder 321, and a second rotary motor 323. The second cylinder 321 drives the opening and closing of the second bending die 322, and the second rotary motor 323 drives the second bending die 322 to rotate. The second bending die 322 consists of an upper die and a lower die. The upper die, driven by the second cylinder 321, performs the opening and closing actions. When the tube 4 is fed to a preset position, the second bending die 322 closes to clamp the tube 4. Then, the second rotary motor 323 rotates, thereby realizing the bending action.

[0045] refer to Figure 3 The bending mechanism 3 also includes a first lifting cylinder 331 and a second lifting cylinder 332;

[0046] The first lifting cylinder 331 drives the first bending part 31 to move vertically; a guide rail structure can be provided between the first lifting cylinder 331 and the first bending part 31, and the first bending part 31 can move vertically along the guide rail. The first bending part 31 adjusts the relative position between the first bending die 312 and the pipe 4 through vertical movement, so that the pipe 4 can smoothly enter and leave the first bending die 312.

[0047] The second lifting cylinder 332 drives the second bending part 32 to move vertically; a guide rail structure can be provided between the second lifting cylinder 332 and the second bending part 32, and the second bending part 32 can move vertically along the guide rail. The second bending part 32 adjusts the relative position between the second bending die 322 and the pipe 4 through vertical movement, so that the pipe 4 can smoothly enter and leave the second bending die 322.

[0048] refer to Figure 3 and Figure 4 The bending mechanism 3 also includes a translation part 34, which drives the first bending part 31 and the second bending part 32 to move horizontally.

[0049] After the first bending part 31 completes the bending action, the translation part 34 drives the second bending part 32 to move toward the pipe 4. Similarly, after the second bending part 32 completes the bending action, the translation part 34 drives the first bending part 31 to move toward the pipe 4.

[0050] The translation section 34 includes a translation cylinder 341, a second guide rail 342, and a second slide plate 343;

[0051] The output end of the translation cylinder 341 is connected to the second slide plate 343;

[0052] The second slide plate 343 is slidably connected to the second guide rail 342;

[0053] Both the first bending part 31 and the second bending part 32 are connected to the second sliding plate 343, and both the first lifting cylinder 331 and the second lifting cylinder 332 are connected to the second sliding plate 343.

[0054] The translation cylinder 341 drives the second slide plate 343 to move horizontally, thereby causing the first bending part 31 and the second bending part 32 to move horizontally.

[0055] refer to Figure 5 and Figure 6 Both the first bending die 312 and the second bending die 322 are provided with a bending guide groove 3120, a straight groove 3121, and an arc groove 3222. Before bending, the part of the pipe 4 to be bent is placed in the straight groove 3121, and the already bent part is placed in the arc groove 3222. When the bending action is performed, the pipe 4 is bent along the bending guide groove 3120.

[0056] refer to Figures 8 to 10 The clamping and feeding mechanism 1 includes a clamping part 11 and a feeding part 13;

[0057] The clamping part 11 includes a chuck 111, a sleeve 112 and a clamping cylinder 113. The clamping cylinder 113 drives the sleeve 112 to move along the axial direction of the chuck 111. The chuck 111 is a variable diameter chuck structure. The sleeve 112 can cause the chuck 111 to change diameter, thereby clamping and releasing the pipe 4.

[0058] The feed unit 13 can drive the clamping unit 11 to move;

[0059] The feeding unit 13 includes a lead screw 131, a feeding motor 132, a first slide plate 133 and a first guide rail 134. The first slide plate 133 is slidably connected to the first guide rail 134. The nut block of the lead screw 131 is connected to the first slide plate 133. The feeding motor 132 is drivenly connected to the lead screw 131. The clamping unit 11 is connected to the first slide plate 133.

[0060] The pipe 4 is inserted into the chuck 111. The clamping cylinder 113 drives the sleeve 112 to move, thereby causing the chuck 111 to contract and clamp the pipe 4. Then, the feed part 13 drives the clamping part 11 to move, thereby realizing the feeding of the pipe 4.

[0061] refer to Figure 8 The clamping and feeding mechanism 1 also includes a support part 12, which includes a support cylinder 121 and a support block 122. The support cylinder 121 and the support block 122 are connected. The support block 122 is provided with an insertion hole.

[0062] The support department 12 provides support to the end of pipe 4;

[0063] The end of the tube 4 can be connected to the insertion hole to support the tube 4; when the tube 4 is fed to the clamping feed mechanism 1, the support part 12 also serves to limit the position of the tube 4.

[0064] refer to Figure 8 It also includes an auxiliary clamping mechanism 2, which is located near the bending mechanism 3. The auxiliary clamping mechanism 2 includes a clamping rod 21 and an auxiliary clamping cylinder 22.

[0065] Two clamping rods 21 are symmetrically arranged, and the two clamping rods 21 are arranged in a V shape. Each clamping rod 21 is connected to an auxiliary clamping cylinder 22.

[0066] During the bending process, the auxiliary clamping mechanism 2 clamps the pipe 4, further improving the positional accuracy and stability of the pipe 4, thereby improving the bending quality.

[0067] When the pipe 4 is long and the clamping part 11 needs to reciprocate multiple times to perform feeding, the auxiliary clamping mechanism 2 can temporarily clamp the pipe 4. Then, the clamping part 11 releases the pipe 4 and moves backward. Then, the clamping part 11 clamps the pipe 4 again. Then, the auxiliary clamping mechanism 2 releases, and the clamping part 11 drives the pipe 4 to move forward.

[0068] After the pipe 4 is bent, the auxiliary clamping mechanism 2 clamps the pipe 4, the clamping part 11 releases the pipe 4 and moves backward, causing the pipe 4 to disengage from the clamping part 11, which facilitates the subsequent unloading and transfer of the pipe 4.

[0069] The above description only discloses some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
