Description

Technical Field

[0001] The invention relates to a port expansion and shaping device, which is particularly suitable for use in port expansion of claw-type tees. Background Art

[0002] Traditional copper fittings small elbows such as Figure 3 As shown, the pipe opening 16 and the pipe opening 17 have the same height and belong to conventional elbows. A continuous serpentine S bending process can be used. Figure 1 As shown in 2, it is then sawed in the middle on a sawing machine (the height after sawing is the size required by the customer). This process not only has high production efficiency but also a high pass rate. At the same time, there are only material heads at both ends, which greatly reduces the waste of material heads and the processing cost is very low.

[0003] Since the hook is bent Figure 2 As shown, since the pipe mouth 14 and the pipe mouth 15 have the same height and cannot be sawed on a sawing machine, the continuous serpentine S-bending process cannot be used. At present, the industry can only use a single bending process, and then manually fine-beat the pipe mouth 14 and the pipe mouth 15 to meet the customer's height requirements. Not only is the single bending process inefficient, but the manual fine-beating process is also inefficient. At the same time, the single bending process also has material heads. The processing cost of the single bending process is 5% lower than the profit margin of the continuous serpentine S-bending process. With the increasingly fierce market competition, how to make the fishhook elbow adopt the continuous serpentine S-bending process to reduce processing costs and improve the core competitiveness of the enterprise is an important issue that needs to be urgently solved in the industry. Summary of the invention

At the same time, the linear guide slider drives the sawing mold and the serpentine S tube to move forward together. When the serpentine S tube contacts the saw blade, it continues to move forward until the material head of the elbow at the front end of the serpentine S tube is sawed off, then stops moving forward, and then moves the linear guide slider backward, driving the sawing mold and the serpentine S tube to move backward together until they return to their initial position.

[0007] Step 2: Flip the serpentine S tube 180°, place the second elbow of the serpentine S tube into the S-shaped cavity, push the linear guide slider to move forward, and at the same time, the linear guide slider drives the sawing mold and the serpentine S tube to move forward together. When the serpentine S tube contacts the saw blade, it continues to move forward until the fishhook elbow at the front end of the serpentine S tube is sawed off, and the fishhook elbow falls into the blanking track and stops moving forward. Then move the linear guide slider backward, driving the sawing mold and the serpentine S tube to move backward together until they return to their initial position.

[0008] Step 3: Flip the serpentine S tube 180°, place the third elbow of the serpentine S tube into the S-shaped cavity, push the linear guide slider to move forward, and at the same time, the linear guide slider drives the sawing mold and the serpentine S tube to move forward together. When the serpentine S tube contacts the saw blade, it continues to move forward until the second fishhook elbow at the front end of the serpentine S tube is sawed off, the fishhook elbow falls into the blanking track, stops moving forward, and then moves the linear guide slider backward, driving the sawing mold and the serpentine S tube to move backward together until they return to their initial position.

[0009] Step 4: Repeat step, step, step, until all the serpentine S-tubes are sawn into fishhook elbows.

[0010] The device comprises a motor, a connecting block, a saw blade and a linear guide slider.

When the serpentine S tube 2 contacts the saw blade 9, it continues to move forward until the fishhook elbow at the front end of the serpentine S tube 2 is sawed off, and the fishhook elbow falls into the blanking track 4, stops moving forward, and then moves the linear guide slider 6 backward, driving the sawing mold 3 and the serpentine S tube 2 to move backward together until the initial position is restored.

[0025] Step 3: Flip the serpentine S tube 2 180°, place the third elbow of the serpentine S tube into the S-shaped cavity 5, push the linear guide slider 6 to move forward, and at the same time, the linear guide slider 6 drives the sawing mold 3 and the serpentine S tube 2 to move forward together. When the serpentine S tube 2 contacts the saw blade 9, it continues to move forward until the second fishhook elbow at the front end of the serpentine S tube 2 is sawed off, and the fishhook elbow falls into the blanking track 4, stops moving forward, and then moves the linear guide slider 6 backward, driving the sawing mold 3 and the serpentine S tube 2 to move backward together until the initial position is restored.
