Abstract
The metal shell making process includes cutting wound metal sheet lengthwise into metal strip with width equal to the perimeter of required conduct in a cutter; winding the metal strip lengthwise into semi-product tube in a winder and pressing in a conduct press into metal strip with width equal to the perimeter of required conduct in a cutter, winding the metal strip length wise into circular conduct; welding seam with a high frequency induction welder and setting the welded long tube; and cutting the metal tube into metal shell in the required sizes. The process of the present invention has high production efficiency and is suitable for various precise metal shells in different sizes.
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, both loses time like this, 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 machine is by the dress part in metal-back, 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 gold that width is required conduit girth along its length direction
Belong to lath and be rolled into volume;
(2) laths of metal with well cutting is an axle with its length, with the conduit forming press it is pressed into the tubular type shape;
(3) adopt high frequency induction welding method welding pipe sealing, and again by correcting the length that mould will weld sealing
Pipe typing growth metal catheter finished product;
(4), 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) it is required conduit girth that the metallic plate 1 that will spool with cutting machine 8 cuts into width along its length direction
Laths of metal 2, and be rolled into 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 will weld sealing by correcting mould 13 again
Long tube typing growth metal catheter finished product 5;
(4), long metal pipe is cut into finished product metal-back 6 according to required size.
Embodiment two:
As shown in Figure 2,
(1) it is required conduit girth that the metallic plate 1 that will spool with cutting machine 8 cuts into width along its length direction
Laths of metal 2, with punch 10 laths of metal 2 is bored a hole into holes 101 metal according to required hole count
Lath;
(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 tubular type with conduit forming press 4
Shape;
(4) adopt high frequency induction welding method welding pipe sealing, and will weld sealing by correcting mould 13 again
Long tube typing growth metal catheter finished product 5;
(5), long metal pipe is cut into the finished product metal-back with cutting machine according to required size.
Claims (2)
1. metal shell making process is characterized in that production process is:
(1) metallic plate that will spool with cutting machine cuts into the gold that width is required conduit girth along its length direction
Belong to lath and be rolled into volume;
(2) laths of metal with well cutting is an axle with its length, with the conduit forming press it is pressed into the tubular type shape;
(3) adopt high frequency induction welding method welding pipe sealing, and again by correcting the length that mould will weld sealing
Pipe typing growth metal catheter finished product;
(4), long metal pipe is cut into the metal-back finished product according to required size.
2. metal shell making process according to claim 1, it is characterized in that after finishing first step operation, that is: suitable its length direction of metallic plate that will spool with cutting machine cuts into after the metallic plate that width is required conduit girth, after also can boring a hole into laths of metal with holes to laths of metal according to required hole count with punch earlier, carry out next step operation again.
