Description

Technical Field

[0001] This utility model relates to the technical field of pipe expansion and contraction production line, specifically a multi-station automatic pipe expansion and contraction production line. Background Technology

[0002] The multi-station automatic pipe expansion and contraction production line is a multi-step automated production line for expanding and contracting pipe holes.

[0003] Based on the above, the inventors have discovered that there are currently many multi-station automatic pipe expansion and contraction production lines on the market. However, in general, these production lines require workers to manually fix the pipes onto the production line before using a pipe cone to expand the holes and a pipe shrinking mold to shrink them. This easily increases the workload of the workers and requires repeated equipment changes to process the pipes, reducing the efficiency of the production line. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a multi-station automatic pipe expansion and contraction production line, aiming to achieve a more practical purpose. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a multi-station automatic expansion and contraction hole production line for pipes, including a conveyor belt, a bottom block on the outer wall of the conveyor belt, a pipe body on the inner wall of the bottom block, a limiting mechanism on one side of the conveyor belt, and a driving mechanism on the outer wall of the conveyor belt. The limiting mechanism includes: An electric telescopic rod is fixed to one side of a conveyor belt. A top plate is fixed to the output end of the electric telescopic rod, and a top block is fixed to the outer wall of the top plate. The top block is located at the top of the bottom block.

[0005] As a preferred embodiment of this utility model, the inner wall of the top block has four columns that slide, and the bottom ends of the four columns are fixed to the top end of the bottom block.

[0006] As a preferred embodiment of this utility model, the bottom end of the top block has two grooves, and the inner walls of the two grooves are slidably provided with protrusions, and the bottom ends of the two protrusions are fixed to the top end of the bottom block.

[0007] As a preferred embodiment of this utility model, the dimensions of the vertical cross-sectional area of ​​the outer walls of the two protrusions are matched with the dimensions of the vertical cross-sectional area of ​​the inner walls of the groove.

[0008] As a preferred embodiment of this utility model, the driving mechanism includes: An orifice plate is fixed to the outer wall of the conveyor belt on one side. A hydraulic pump is fixed to the top of the orifice plate, and a groove block is fixed to the output end of the hydraulic pump. The outer wall of the groove block slides against the inner wall of the orifice plate.

[0009] As a preferred technical solution of this utility model, a sliding plate is slidably mounted on the inner wall of the groove block, a conical tube is fixed at the top of the sliding plate, a tube shrinking mold is provided on one side of the conical tube, and the bottom end of the tube shrinking mold is fixed to the top of the sliding plate.

[0010] As a preferred embodiment of this utility model, the inner wall of the groove block is fixed with two square blocks, and the outer walls of the two square blocks are matched with the inner wall of the slide plate.

[0011] The beneficial effects of this utility model are: 1. In this solution, the main body of the pipe is placed on the inner wall of the bottom block. The conveyor belt is controlled to move the bottom block to the bottom of the top block. The operator uses an electric telescopic rod to control the top plate to move the top block up and down above the conveyor belt. After the inner wall of the top block slides against the outer wall of the column, the bottom end of the top block abuts against the top end of the bottom block. The inner wall of the groove at the bottom end of the top block matches the outer wall of the protrusion. Thus, the combination of the top block and the bottom block stably places the main body of the pipe on the inner wall of the bottom block. This allows the operator to better expand and contract the pipe body, avoiding the need for manual limiting of the pipe body during installation. This reduces the operator's workload on the production line and improves the efficiency of the production line.

[0012] 2. In this solution, a sliding plate is used to slide on the inner wall of the slot block to adjust the position of the tube shrinking mold and the conical tube as needed until the inner wall of the sliding plate is engaged with the outer wall of the block. This allows the operator to position the tube shrinking mold or conical tube in the direction directly opposite the tube body. The operator then controls the hydraulic pump to drive the slot block to slide on the perforated plate until the tube shrinking mold or conical tube is fitted and installed between the tube shrinking mold or conical tube and the tube body, thereby enabling the production line to quickly and automatically expand and shrink the tube body.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example: Figures 1-5 As shown, this utility model discloses a multi-station automatic expansion and contraction hole production line for pipes, including a conveyor belt 1, a bottom block 2 on the outer wall of the conveyor belt 1, a pipe body 3 on the inner wall of the bottom block 2, a limiting mechanism 4 on one side of the conveyor belt 1, and a driving mechanism 5 on the outer wall of the conveyor belt 1. Limiting mechanism 4 includes: An electric telescopic rod 41 is fixed to one side of the conveyor belt 1. A top plate 42 is fixed to the output end of the electric telescopic rod 41. A top block 43 is fixed to the outer wall of the top plate 42. The top block 43 is located at the top of the bottom block 2. Four columns 44 slide on the inner wall of the top block 43. The bottom ends of the four columns 44 are all fixed to the top of the bottom block 2. Two grooves 45 are opened at the bottom of the top block 43. Protrusions 46 slide on the inner wall of the two grooves 45. The bottom ends of the two protrusions 46 are all fixed to the top of the bottom block 2. The size of the vertical cross-sectional area of ​​the outer wall of the two protrusions 46 is matched with the size of the vertical cross-sectional area of ​​the inner wall of the grooves 45.

[0017] As attached Figure 1 , Figure 2 and Figure 5 As shown, the drive mechanism 5 includes: The perforated plate 51 is fixed to the outer wall of the conveyor belt 1 on one side. A hydraulic pump 52 is fixed to the top of the perforated plate 51. A groove block 53 is fixed to the output end of the hydraulic pump 52. The outer wall of the groove block 53 slides against the inner wall of the perforated plate 51. A sliding plate 54 slides against the inner wall of the groove block 53. A conical tube 55 is fixed to the top of the sliding plate 54. A tube shrinking mold 56 is provided on one side of the conical tube 55. The bottom end of the tube shrinking mold 56 is fixed to the top of the sliding plate 54. Thus, the operator controls the hydraulic pump 52 to drive the groove block 53 to slide on the perforated plate 51 until the tube shrinking mold 56 or the conical tube 55 is fitted and installed between the tube body 3, thereby realizing the production line to quickly and automatically expand and shrink the holes of the tube body 3.

[0018] As attached Figure 1 and Figure 5 As shown, two square blocks 6 are fixed to the inner wall of the groove block 53. The outer walls of the two square blocks 6 are matched with the inner wall of the slide plate 54, so that the tube shrinking mold 56 or the conical tube 55 can remain stable after moving to the direction facing the tube body 3.

[0019] Working principle: In use, the pipe body 3 is placed on the inner wall of the bottom block 2. The conveyor belt 1 is controlled to move the bottom block 2 below the top block 43. The operator uses the electric telescopic rod 41 to control the top plate 42 to move the top block 43 up and down above the conveyor belt 1. After the inner wall of the top block 43 slides against the outer wall of the column 44, the bottom end of the top block 43 abuts against the top end of the bottom block 2. The inner wall of the groove 45 at the bottom end of the top block 43 matches the outer wall of the protrusion 46. Thus, the combination of the top block 43 and the bottom block 2 stably places the pipe body 3 on the inner wall of the bottom block 2, so that the operator can better expand and contract the pipe body 3, avoiding the need for manual operation of the pipe. The main body 3 is installed with a limit position to reduce the workload of workers on the production line and improve the efficiency of the production line. The slide plate 54 slides on the inner wall of the groove block 53 to adjust the position of the tube shrinking mold 56 and the conical tube 55 as needed until the inner wall of the slide plate 54 is engaged with the outer wall of the block 6. This allows the workers to position the tube shrinking mold 56 or the conical tube 55 in the direction directly opposite the main body 3 of the pipe. The workers then control the hydraulic pump 52 to drive the groove block 53 to slide on the perforated plate 51 until the tube shrinking mold 56 or the conical tube 55 is fitted and installed between the main body 3 of the pipe, thereby enabling the production line to quickly and automatically expand and shrink the holes of the main body 3 of the pipe.
