Embodiment 1

[0020] Such as figure 1 As shown, it is a T-shaped tee with an outer diameter of Φ12. First, the filling medium for the extruded pipe fitting is prepared, and the industrial salt NaCl 30% is 600g and the ammonium bicarbonate NH4HCO3 70% is 1400g and mixed evenly.

[0021] The manufacturing process steps of extruded pipe fittings are as follows:

[0022] 1. Cutting the pipe fittings, intercepting 50 copper pipes with an outer diameter of Φ12 and a length of 80mm;

[0023] 2. Use a powder filling machine to fill the pipe-through parts after blanking in step 1 with medium, and measure the filling density so that the extrusion length requirement is met. The measured density is 0.5g / ;

[0024] 3. Extrude the pipe fitting after filling the medium in step 2 with a hydraulic press, and there is no time interval between the completion of the filling medium process in the described step 2 and the beginning of the extrusion process in the step 3;

[0025] 4. Place the extruded pipe fit...

Embodiment 2

[0029] Such as figure 2 As shown, it is a Y-shaped tee with an outer diameter of Φ9.0. First, prepare the filling medium for the extruded pipe fittings, and mix them uniformly according to industrial salt NaCl 99% in total 2970g and ammonium bicarbonate NH4HCO3 1% in total 30g.

[0030] The manufacturing process steps of extruded pipe fittings are as follows:

[0031] 1. Cutting the pipe fittings, intercepting 100 iron pipes with an outer diameter of Φ9.0 and a length of 80mm;

[0032] 2. Use a powder filling machine to fill the pipe-through parts after blanking in step 1 with medium, and measure the filling density so that the extrusion length requirement is met. The measured density is 2.0g / ;

[0033] 3. Extrude the pipe fitting after filling the medium in step 2 with a hydraulic press, and the interval between the completion of the filling medium process in the described step 2 and the start of the extrusion process in the step 3 is 12 hours;

[0034] 4. Temper the extru...

Embodiment 3

[0041] Such as image 3As shown, it is a three-jaw type tee with an outer diameter of Φ9.5. First, prepare the filling medium for the extruded pipe fitting, and mix evenly according to 1625g of industrial salt NaCl 65% and 875g of ammonium bicarbonate NH4HCO3 35%.

[0042] The manufacturing process steps of extruded pipe fittings are as follows:

[0043] 1. Cutting the pipe fittings, intercepting 50 aluminum pipes with an outer diameter of Φ9.5 and a length of 100mm;

[0044] 2. Use a powder filling machine to fill the pipe-through parts after blanking in step 1 with medium, and measure the filling density so that the extrusion length requirement is met. The measured density is 3.5g / ;

[0045] 3. Squeeze the pipe fitting after filling the medium in step 2 with a hydraulic press, and the interval between the completion of the filling medium process in the described step 2 and the start of the extrusion process in the step 3 is 72 hours;

[0046] 4. Temper the extruded pipe fi...

The packing medium of the extruded tube piece provided by the invention has the advantages of simplicity and convenience in extrusion, easiness in commercial process, effective reduction in production cost, and health and environmental protection.

Description

technical field [0001] The invention belongs to the field of pipeline engineering, and in particular relates to a filling medium for an extruded pipeline piece that is simple and convenient to extrude, easy to industrialized production, can effectively reduce production costs, and is healthy and environment-friendly, and a manufacturing process of the extruded pipeline piece. Background technique [0002] Pipe fittings are widely used in the field of pipe engineering, especially in refrigeration, chemical, construction and food industries. At present, the known extrusion molding technologies include lead-filled extrusion, oil-injected extrusion, and water-injected extrusion. The development of oil-injected or water-injected extrusion is slow due to factors such as high technical difficulty, high equipment cost, and unsatisfactory extrusion length. And lead-filled extrusion is still dominated by lead-filled extrusion in the current technology because of its extrusion molding ...
