The invention provides a
pipe limiting point forming clamp which is provided with an installation base. A fixing part and a connecting part which are connected are arranged on the installation base. A forming device is arranged in the fixing part and the connecting part, a spring head at the left end of the forming device penetrates and stretches out of a depth adjusting part to be arranged at the outer portion of the depth adjusting part, and a
central spindle at the right end of the forming device penetrates and stretches out of the fixing part to be arranged at the outer portion of the fixing part. The part, stretching out of the depth adjusting part, of the spring head is inserted in the left side of the depth adjusting part and abuts against the interior of a
pipe hole in the right end of a
pipe on the left end face of the depth adjusting part. A
handle is fixedly connected with an eccentric wheel, the eccentric wheel pushes the
central spindle to move leftwards or rightwards by rotating the
handle, then the spring head is controlled to be opened or closed, and therefore forming of a limiting bump on the pipe is achieved. According to the pipe limiting point forming clamp, it can be ensured that
welding gaps are uniform in the inserting connecting and
welding process of a
flow diversion pipe of a
heat exchanger, operation is simple, efficiency is high, consistency of the
insertion connecting depth of the product can be effectively ensured, the product quality is improved, the product appearance is good, the
insertion connecting depth size range of the pipe is adjustable, and the pipe limiting point forming clamp is suitable for different work occasions.
