Problems solved by technology

[0002] The traditional production method of lead sleeve adopts gravity casting, which is obtained by pouring molten metal into the mold and waiting for it to solidify and cool. This casting method needs to dissolve lead in the furnace, and a large amount of lead fume will be generated during the production process, which will affect the environment in the long run. cause irreparable pollution
In addition, the quality of the lead sleeve obtained by the casting molding will have defects such as rough surface, insufficient casting, voids, cracks, etc., and subsequent high-strength post-processing is required

Embodiment Construction

[0036] The present case will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] This case involves a kind of equipment for manufacturing warm and cold extruded forged pipes, such as Figure 1-5 As shown, it mainly includes a base 1 , an extrusion head mechanism 2 and an extrusion driving mechanism 3 arranged on the base 1 .

[0038] The extruder head mechanism 2 mainly includes a main body 21 and a heating body 22 , and the heating body 22 is connected to one end of the main body 21 . The main body 21 is axially provided with a feed channel that runs through. Preferably, the feed channel includes an extrusion straight channel 211 and a feeding shrinkage channel 212. ) has a material inlet 210. The heating body 22 is provided with a through annular heating flow channel along the axial direction. The heating flow channel includes a heating expansion channel 221, a heating shrinking channel 222 and an extrusion ...

Abstract

The invention discloses an apparatus used for manufacturing a warm and cold swaging stay tube and a method for manufacturing a lead sleeve by using the apparatus. The apparatus comprises a base, an extruder head mechanism and an extrusion driving mechanism, wherein the extruder head mechanism comprises a body and a heating body, the body is provided with a material channel, the material channel has a material inlet, the heating body is provided with a penetrating annular heating runner, the heating runner comprises a heating expanding channel, a heating shrinkage channel and an extrusion straight channel which are successively connected, the free end of the heating expanding channel is connected with a material channel, and the extrusion driving mechanism comprises an ejector beam which can be inserted from the material inlet and a driving unit driving the ejector beam to stretch out and draw back. Compared with a traditional gravity casting method, the method provided by the invention has the advantages of no discharge of lead smoke, no pollution to the environment, conservation of energy, environment friendliness and substantial production benefits; and the prepared lead sleeve has no defects like surface roughness, misrun, cavities and cracks, has an accurate size, high relative density and excellent product quality and is hard to oxidize.

Description

technical field [0001] The invention relates to the technical field of manufacturing pipe fittings, in particular to a device for manufacturing warm and cold extrusion forging and drawing pipes. Background technique [0002] The traditional production method of lead sleeve adopts gravity casting, which is obtained by pouring molten metal into the mold and waiting for it to solidify and cool. This casting method needs to dissolve lead in the furnace, and a large amount of lead fume will be generated during the production process, which will affect the environment in the long run. cause irreparable pollution. In addition, the quality of the lead sheath obtained by casting may have defects such as surface roughness, insufficient casting, voids, cracks, etc., and subsequent high-strength post-processing is required. At present, other metal pipe fittings similar to lead sleeves are produced by gravity casting, all of which have the above-mentioned problems. In view of this, the...
