Description
Technical field
The present invention relates to a kind of appliance plug, be meant the pin manufacture method and the special equipment thereof that are installed on the plug especially.
Background technology
The pin of the appliance plug of selling on the market at present or using substantially all is solid, good in order to conduct electricity, ordinary priority adopts copper product to make, particularly the price of copper is constantly soaring along with metal material, also increase greatly with copper material its manufacturing cost of appliance plug as solid pin, in order to reduce materials, the research of part producer is made pin hollow, because technology is immature, when making square hollow pin, the general using sheet copper is folding to form, and an end cuts out and grabs mouthful also folding closing up together therein, thereby forms insertion end, but the insertion end with the produced pin of this technology is not sealed, when being used, occur easily damaging with socket, fault such as block, bring potential safety hazard, as adopt the welding means further processing joint sealing is got up, the processing trouble, and the required precision strictness of this type of welding equipment, its purchasing price is also high, thereby can't effectively lower production cost of products.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of safe in utilization, operation simple, save material, plug base pin manufacture method and special equipment thereof that production cost is low.
The technical solution adopted in the present invention is:
A kind of method of making plug base pin, its manufacturing process mainly is divided into following processing step:
A, divide segment with hollow circular-tube;
B, utilize the rotary press head of machine that pipe one end is carried out rotation press closing, the pipe end is out of shape under the high temperature that pressure and high speed rotary grinding produce, form hemispheric closing end;
C, circular body forged the body that is pressed into rectangular cross section;
D, to closing end punching press shaping, make closing end be trapezoidal shape.
Employed equipment when making above-mentioned plug base pin with the sealing of pipe end, but anchor clamps with held circular pipe, outside the pipe end rotary press head is arranged, described rotary press head is inner concavity, and rotary press head is connected with the power set that can make its rotation and move at the pipe axis direction.
The invention has the beneficial effects as follows: the design's plug base pin is that the cross section is the seamless hollow cylinder of rectangle, the contact area that can keep conductor between pin and the socket, can reduce again simultaneously and make the copper product that pin consumed, reduce cost, improve the competitiveness of product in market; The method of making pin of the present invention has solved the technical barrier that utilizes hollow circular-tube to make the square plug pin, and its operation is simple, the equipment less investment; In addition, the design has made seamless closing end by the method for high speed spinning, has guaranteed safety in utilization.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the product schematic diagram that the present invention processes by processing step a;
Fig. 2 is the product schematic diagram that the present invention processes by processing step b;
Fig. 3 is the product schematic diagram that the present invention processes by processing step c;
Fig. 4 is the product schematic diagram that the present invention processes by processing step d.
Embodiment
A kind of plug base pin, it comprises cylinder 1, described cylinder 1 is that the cross section is the seamless pipe of rectangle, have wide 11 and leptoprosopy 12, cylinder 1 inner hollow, cylinder 1 one ends are openings 2, the other end is a closing end 3, and described closing end 3 has the importing inclined-plane 31 of symmetry, in use; When pin inserts socket, can import, can not damage consuming devices such as socket, guarantee safety in utilization than being easier to.
The present invention is used for making the method for above-mentioned plug base pin, and its process mainly is divided into following processing step:
A, with cutting machine hollow circular-tube is divided into segment, as shown in Figure 1;
B, utilize the rotary press head of machine that pipe one end is carried out rotation press closing, the pipe end is out of shape under the high temperature that pressure and high speed rotary grinding produce, form hemispheric closing end, as shown in Figure 2;
C, circular body is forged the body that is pressed into rectangular cross section, as shown in Figure 3;
D, to closing end punching press shaping, make closing end be trapezoidal shape, as shown in Figure 4.
The suitable length of the present invention when the described hollow circular-tube length of processing step a cooperates with socket according to pin when implementing, every segment pipe is cut into 32mm and grows, and certain every section also can be 28mm, 35mm or other length, can decide as required.
Similarly, the present invention is the copper material of 0.35mm at the described hollow circular-tube employing of the processing step a thickness of pipe; The external diameter of hollow circular-tube is 7.4mm, make the product that processes not only meet instructions for use, can reduce simultaneously the consumption of copper material again, have a significant effect to reducing cost, the parameter of above-mentioned pipe is an optimal way of the present invention, can be also in actual production can select the material of other thickness of pipe, caliber according to market demand or at the electrical equipment of different capacity, as, the thickness of pipe can be 0.4mm, 0.8mm etc., and external diameter of pipe also can be 6.1mm, 8mm, 8.5mm etc.
Further, in processing step c, the length of described square-section is 8mm, and width is 4mm, and certainly, this parameter is not unique, and in actual production, the size in cross section can be designed to other length, as 5mm * 3mm, 6mm * 4mm, 8mm * 5mm etc.
Among the present invention, the sealing the present invention of pipe end to have been used special equipment, but this equipment has the anchor clamps of held circular pipe, outside the pipe end, rotary press head is arranged, described rotary press head is inner concavity, rotary press head is connected with the power set that can make its rotation and move at the pipe axis direction, when rotation press closing, in order to form good hemispherical closing end, need suitably to control the high temperature that produces because of friction between rotary press head high speed rotating and the tube end, be not easy to make copper pipe to be out of shape as temperature is low, as the too high copper pipe that burns out easily of temperature, make its deterioration in physical properties, the rotating speed of rotary press head of the present invention is that per minute 2000～2800 changes.
The design's plug base pin is that the cross section is the seamless hollow cylinder of rectangle, can keep the contact area of conductor between pin and the socket, can reduce again simultaneously and make the copper product that pin consumed, and has reduced cost, has improved the competitiveness of product in market; The method of making pin of the present invention has solved the technical barrier that utilizes hollow circular-tube to make the square plug pin, and its operation is simple, the equipment less investment; In addition, the design has made seamless closing end by the method for high speed spinning, has guaranteed safety in utilization.
The above is the preferred embodiment of the present invention, and it does not constitute limiting the scope of the invention, so long as realize that with essentially identical means purpose of the present invention all should belong to protection scope of the present invention.
