Abstract
The present invention relates to a metal shell making method which comprises: a reeled metal plate is cut into metal plate strips whose width is the perimeter of a needed conduit by a cutter along a lengthwise direction; the cut metal plate strips are reeled into a tubular semi-product using the length of the metal plate strips as an axis by a winding machine, and then, the semi-product is pressed into a circular pipe shape by a conduit pressing machine; circular pipe joint openings are welded by high-frequency induction, and an obtained long pipe whose joint openings are welded by a rectification die is shaped into a long metal conduit finished product; according to required size, the long metal pipe is cut into metal shells. The present invention uses a small amount of human power for enhancing production efficiency in a short time, and when metal shells of different specifications are processed, the mass production of precise metal shells can be achieved without changing working procedures.
Description
Technical field
The present invention relates to a kind of method for metal working, particularly metal shell making process.
Background technology
The processing method of metal current shell is: (1) spools metallic plate with plate circle machine, (2) vertically cut into a few strip metal plates with cutting machine again, (3) are cut into the metal plate with cutoff tool, and (4) are rolled into circle to the metal plate, (5) with the welding of Plasma welding, (6) processing metal shell.This processing mode, production equipment and procedure complexity, required manpower and time are many.If during processing plurality of specifications (about 10 kinds) metal-back, during every change product specification, procedure also needs change, so promptly loses time, and operating efficiency is also very low, and a large amount of production difficulty are big.And the metal plate needs Plasma welding one by one, very easily produces substandard products when welding like this, and welds good metal-back inner face and slightly make, and when in metal-back part being installed, many substandard products takes place.
Summary of the invention
The object of the present invention is to provide and a kind ofly can overcome above-mentioned deficiency, production efficiency height, the metal shell making process that quality is high.
The object of the present invention is achieved like this, and metal shell making process is characterized in that production process is:
(1) metallic plate that will spool with cutting machine cuts into the laths of metal that width is required conduit girth along its length direction, with punch laths of metal is bored a hole into laths of metal with holes according to required hole count;
(2) with up-coiler laths of metal with holes is rolled into volume;
(3) be axle with laths of metal with holes with its length, it be pressed into round tube shape with the conduit forming press;
(4) adopt high frequency induction welding method welding pipe sealing, and again by correcting the long tube typing growth metal catheter finished product that mould will weld sealing;
(5), long metal pipe is cut into the metal-back finished product according to required size.
The present invention enhances productivity with a spot of manpower at short notice owing to adopt above-mentioned operation, and during the metal-back of processing different size, need not to change production process and just can produce in a large number.Because of the present invention is the substandard products that produce when adopting the HFI welding mode to significantly reduce welding, the metal-back of amiss precision not when being processed into by the dress part.
Description of drawings
Provide specific embodiment below in conjunction with accompanying drawing, further specify the present invention and how to realize.
Fig. 1 is a technological process of the present invention;
Fig. 2 is the technological process of processing belt mesoporous metal shell of the present invention;
Fig. 3 is the technological process before improving;
Wherein 7 is to be cut off the plate that cutter 11 cuts off, the 12nd, and the Plasma welding.
The specific embodiment
Embodiment one:
As shown in Figure 1, metal shell making process is following operation;
(1) metallic plate 1 that will spool with cutting machine 8 cuts into the laths of metal 2 that width is required conduit girth along its length direction, and is rolled into volume 3 with up-coiler;
(2) laths of metal 2 with well cutting is an axle with its length, with conduit forming press 4 it is pressed into the tubular type shape;
(3) adopt high frequency induction welding method welding pipe sealing, and again by correcting the long tube typing growth metal catheter finished product 5 that mould 13 will weld sealing;
(4), long metal pipe is cut into finished product metal-back 6 according to required size.
Embodiment two:
As shown in Figure 2,
(1) metallic plate 1 that will spool with cutting machine 8 cuts into the laths of metal 2 that width is required conduit girth along its length direction, laths of metal 2 is bored a hole into holes 101 laths of metal with punch 10 according to required hole count;
(2) with up-coiler with holes 101 laths of metal is rolled into 3;
(3) be axle with holes 101 laths of metal 2 with its length, it be pressed into the tubular type shape with conduit forming press 4;
(4) adopt high frequency induction welding method welding pipe sealing, and again by correcting the long tube typing growth metal catheter finished product 5 that mould 13 will weld sealing;
(5), long metal pipe is cut into the finished product metal-back with cutting machine according to required size.
Claims (1)
1. metal shell making process is characterized in that production process is:
(1) metallic plate that will spool with cutting machine cuts into the laths of metal that width is required conduit girth along its length direction, with punch laths of metal is bored a hole into laths of metal with holes according to required hole count;
(2) with up-coiler laths of metal with holes is rolled into volume;
(3) be axle with laths of metal with holes with its length, it be pressed into round tube shape with the conduit forming press;
(4) adopt high frequency induction welding method welding pipe sealing, and again by correcting the long tube typing growth metal catheter finished product that mould will weld sealing;
(5), long metal pipe is cut into the metal-back finished product according to required size.
