Embodiment 1

[0021] see figure 1 , figure 2 As shown, a bicycle aluminum alloy riser forming equipment includes a riser shape mold and a hydraulic punch mechanism, and the riser shape mold includes a structurally symmetrical upper mold 1 and a lower mold 2, and the upper mold 1 and the lower mold 2 are closed to form a bicycle aluminum alloy riser mold cavity 8 in the middle, the front end of the bicycle aluminum alloy riser mold cavity 8 is a closed end and the shape of the bicycle aluminum alloy riser head 6, the rear end It is an open end; the hydraulic punch mechanism includes a retractable main punch 3, the front end of the main punch 3 is shaped like the tail part 4 of a bicycle aluminum alloy riser, and inside the main punch 3 is a A retractable sub-punch 5; the hydraulic punch mechanism can be inserted into the bicycle aluminum alloy standpipe cavity 8 from the open end of the bicycle aluminum alloy standpipe cavity 8.

Embodiment 2

[0023] see figure 1 , figure 2 Shown: a forming process of a bicycle aluminum alloy standpipe, which includes the following steps:

[0024] Step 1) Clamping the upper mold 1 and the lower mold 2 to form the mold cavity 8 of the bicycle aluminum alloy stand pipe;

[0025] Step 2) Putting a solid aluminum billet 7 into the mold cavity 8 of the bicycle aluminum alloy stand pipe;

[0026] Step 3) The hydraulic punch mechanism is inserted into the mold cavity 8 of the bicycle aluminum alloy standpipe, and the aluminum blank 7 is squeezed so that the front end of the aluminum blank 7 squeezes the bicycle aluminum alloy standpipe The closed end of the mold cavity 8 causes the front end of the aluminum billet 7 to be shaped into the shape of the bicycle aluminum alloy riser head 6;

[0027] Step 4) The main punch 3 unloads and retreats to the set position, and at the same time, the sub-punch 5 continues to push into the mold cavity 8 of the bicycle aluminum alloy riser, causing th...

Abstract

The invention discloses equipment for forming a bicycle aluminum alloy upright pipe. The equipment comprises an upright pipe shape mould and an oil hydraulic punch mechanism, wherein the upright pipe shape mould comprises an upper mould and a lower mould which are symmetrical; a bicycle aluminum alloy upright pipe mould cavity is formed between the upper mould and the lower mould which are closed; the front end of the bicycle aluminum alloy upright pipe mould cavity is an enclosed end and has the shape of the head of the bicycle aluminum alloy upright pipe; the back end of the bicycle aluminum alloy upright pipe mould cavity is an open end; the oil hydraulic punch mechanism comprises a retractable main punch; the front end of the main punch has the shape of the tail of the bicycle aluminum alloy upright pipe; a retractable sub-punch is arranged in the main punch; and the oil hydraulic punch mechanism can be inserted into the bicycle aluminum alloy upright pipe mould cavity from the open end of the bicycle aluminum alloy upright pipe mould cavity. The bicycle aluminum alloy upright pipe which is manufactured by the bicycle aluminum alloy upright pipe forming equipment has low material consumption and high forming yield, formed products have the same shape dimension, and further complicated processing by subsequent equipment is not required, so that production cost is greatly lowered and production efficiency is improved.

Description

technical field [0001] The invention relates to an aluminum alloy riser for an automatic vehicle, which belongs to the field of bicycle parts, in particular to a forming equipment and a forming process for an aluminum alloy standpipe of a bicycle.
