[0026] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0027] This technical solution provides a pipe shrinking machine that can achieve fast cutting, including a positioning mechanism 3, a pipe shrinking mechanism 4, and a cutting mechanism 5. The pipe shrinking mechanism 4 and the cutting mechanism 5 are respectively installed on two adjacent sides of the positioning mechanism 3, and the working end of the pipe shrinking mechanism 4 faces the positioning mechanism 3. The cutting mechanism 5 is used to cut the pipes that have been shrunk from the positioning mechanism 3;

[0028] The positioning mechanism 3 includes a positioning base 31 and a positioning block 32. The positioning block 32 is movably arranged vertically above the positioning base 31. The positioning base 31 and the positioning block 32 are jointly used to position and clamp the pipes;

[0029] The blanking mechanism 5 includes a blanking seat 51 and a blanking plate 52. The blanking plate 52 is swingably mounted on the top of the blanking seat 51, and the swing axis of the blanking plate 52 is parallel to the placement direction of the pipe in the positioning base 31. The swing axis of the blanking plate 52 is located in the middle of the bottom surface of the blanking plate 52.

[0030] The blanking plate 52 includes a material taking end 521 and a blanking end 522. The material taking end 521 and the blanking end 522 are respectively located on both sides of the swing axis of the blanking plate 52. Two material taking arms 5211 are protruding from the material taking end 521, and the material taking arms 5211 are respectively located at both ends of the positioning base 31. The material taking arms 5211 are used to remove the pipe from the positioning base 31 when the material taking end 521 tilts upward.

[0031] In the prior art, after the pipe shrinking is completed, common clamping mechanisms such as clamping jaws are generally used for blanking. However, due to the long moving path of the conventional clamping mechanism, the blanking speed of the pipe is slow, thus slowing down the pipe shrinking efficiency of the pipe shrinking machine.

[0032] Therefore, in order to improve the blanking speed of the pipe and prevent it from affecting the operation progress of the automatic pipe shrinking machine, this solution proposes a blanking mechanism 5, which cooperates with the positioning mechanism 3 to effectively achieve the rapid blanking of the pipe (not shown in the figure), as Figure 1 shown. Specifically, when the blanking mechanism 5 is in the standby state, the blanking plate 52 is horizontally arranged, as Figure 2 shown in state (c1). The cooperation between the blanking mechanism 5, the positioning mechanism 3 and the pipe shrinking mechanism 4 is achieved according to the following steps: First, place the pipe between the positioning base 31 and the positioning block 32, and then the positioning block 32 moves downward to press the pipe against the positioning mechanism 3. Then, the pipe shrinking mechanism 4 performs a pipe shrinking operation on the end of the pipe that is positioned and pressed. After the pipe shrinking is completed, the pipe shrinking mechanism 4 first disengages from the end of the pipe, and then the positioning block 32 moves upward and releases the pressing on the pipe. Next, the material taking end 521 of the blanking plate 52 tilts upward, as Figure 2 shown in state (c2). The material taking arms 5211 act on the shrunk pipe and make it disengage from the positioning base 31. The pipe that has disengaged from the positioning base 31 then rolls to the blanking end 522 under the action of the inclined blanking plate 52, thus completing the blanking of the pipe in the positioning mechanism 3. Compared with the clamping blanking in the prior art, this solution uses a rolling blanking method to blank the pipe, making full use of the characteristics of the pipe itself to achieve rapid blanking of the pipe, and has a simple structure and reliable performance.

[0033] It should be noted that in this solution, the feeding process of the pipe in the positioning mechanism 3 can be automatically fed by existing feeding mechanisms such as feeding chains and feeding belts, which is not limited here.

[0034] Further explanation is as follows. The opposite surfaces of the positioning base 31 and the positioning block 32 are both recessed inward, and the positioning base 31 and the positioning block 32 jointly form a positioning groove for accommodating the pipe. The working end of the pipe shrinking mechanism 4 faces the end of the positioning groove.

[0035] The pipe shrinking mechanism 4 moves horizontally and vertically relative to the positioning base 31.

[0036] In a preferred embodiment of this technical solution, the positioning base 31 and the positioning block 32 jointly form a positioning groove (not marked in the figure) for accommodating the pipe, which is more conducive to ensuring the positioning and pressing of the pipe in the positioning mechanism 3 and avoiding the displacement of the pipe during the pipe shrinking process. In addition, the pipe shrinking mechanism 4 can move horizontally and vertically relative to the positioning base 31, so that the pipe shrinking mechanism 4 can adjust its position for pipes of different specifications, further improving the versatility of the automatic pipe shrinking machine.

[0037] It should be noted that the pipe shrinking mechanism 4 can move horizontally relative to the positioning base 31, including but not limited to the horizontal movement of the pipe shrinking mechanism 4 along the placement direction of the pipe in the positioning mechanism 3 and the horizontal movement perpendicular to the placement direction of the pipe in the positioning mechanism 3.

[0038] Further explanation is as follows. The positioning mechanism 3 further includes a positioning baffle 33. The positioning baffle 33 is arranged on one side of the positioning base 31, and the positioning baffle 33 swings relative to the positioning base 31. The positioning baffle 33 is used to abut against the end of the pipe to block the conveyance of the pipe in the positioning base 31 towards the pipe shrinking mechanism 4.

[0039] In another preferred embodiment of this technical solution, a positioning baffle 33 is further added to the positioning mechanism 3. Its action cooperation relationship with the positioning base 31 and the positioning block 32 is as follows: when the positioning mechanism 3 is in the standby state, the movable end of the positioning baffle 33 is misaligned with the extension direction of the positioning groove, as Figure 2 shown in state (c1); when the pipe is placed on the positioning base 31, the positioning baffle 33 first swings downward and makes its movable end opposite to the extension direction of the positioning groove, as Figure 2 shown in state (c3), so as to position the relative position of the pipe in the positioning base 31; then the positioning block 32 moves downward to press the pipe against the positioning mechanism 3. At this time, the positioning baffle 33 can reset upward to prevent it from hindering the pipe shrinking operation of the pipe shrinking mechanism 4 on the pipe.

[0040] Further explanation, the positioning mechanism 3 further includes a rotating motor 34, the rotating motor 34 is arranged on one side of the positioning base 31, the end of the positioning baffle 33 is detachably installed on the output end of the rotating motor 34, and the positioning baffle 33 swings relative to the positioning base 31 through the rotating motor 34.

[0041] Further explanation, the blanking mechanism 5 further includes a blanking driving assembly 53, the blanking driving assembly 53 is arranged at the bottom of the blanking plate 52, and the output end of the blanking driving assembly 53 is connected to the bottom of the blanking end 522, and the blanking driving assembly 53 is used to drive the swinging of the blanking plate 52.

[0042] Further explanation, it further includes an installation platform 6, and the positioning mechanism 3, the pipe shrinking mechanism 4 and the blanking mechanism 5 are all installed on the installation platform 6;

[0043] The blanking driving assembly 53 includes a first hinge seat 531, a telescopic driver 532 and a second hinge seat 533; the blanking end 522 of the blanking plate 52 protrudes from the installation platform 6, the first hinge seat 531 is installed on the side wall of the installation platform 6, the second hinge seat 533 is installed on the bottom of the blanking end 522, the installation end of the telescopic driver 532 is hinged to the first hinge seat 531, and the telescopic output end of the telescopic driver 532 is hinged to the second hinge seat 533. In this way, it is beneficial to simplify the structure and save costs on the premise of ensuring the rapid blanking of the pipe.

[0044] Further explanation, it further includes a receiving frame, and the receiving frame is located directly below the blanking end 522.

[0045] This solution also has a receiving frame (not shown in the figure) directly below the blanking end 522 to facilitate the collection of the pipes after the pipe shrinking is completed.
