Description
Technical field
The invention belongs to detonator with metal shell shell production method, particularly a kind of detonator with metal shell shell drop stamping drawing process.
Background technology
It is all that the cold blank making is in advance become to detonator shell by 25 tons of crankshaft punching machines through the punching stretch of 5 times mostly that China detonator with metal shell shell is produced, mode because of its complex process and employing cold punching, detonator shell production efficiency is low, and very easily there are sand holes, have so after the detonator shell blasting charge of sand holes, once explosive leaks out detonator, transportation or handling process in because the friction between detonator, static have an accident, can have a great impact safely national product, cause the consequence that cannot retrieve.
At present, research about detonator with metal shell shell drop stamping drawing process still belongs to blank at home, therefore, utilize high-frequency electromagnetic heating technique, punching stretch technology is produced and is adopted drop stamping drawing process detonator shell, improve production efficiency and the detonator shell qualification rate of detonator shell, thereby improved the quality of detonator production, be detonator production producer in the urgent need to key technology.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned technical method, a kind of a kind of detonator with metal shell shell drop stamping drawing process that improves detonator production efficiency and product quality is provided.
The technical scheme that technical solution method problem of the present invention adopts is: a kind of detonator with metal shell shell drop stamping drawing process comprises high-frequency heating power device, shearing device and detonator shell decompressor, and high-frequency heating power device, shearing device and detonator shell decompressor comprise high-frequency heating power, spiral electromagnetic heating coil, cylindrical metal material, holding pad, cut-out punch, cut off die, blank guide rail, location-plate, blank mouth, punching stretch punch, stamping cavity die, push rod.
The invention has the beneficial effects as follows: a kind of detonator with metal shell shell drop stamping drawing process can heat the production efficiency that improves detonator shell with punching stretch by high-frequency electromagnetic, reduce the probability that sand holes appear in detonator shell, improved security in detonator production, handling process, the person in assurance detonator production, business process and the safety of national wealth.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, with embodiment, illustrate.
Fig. 1 is the front view of structure in a kind of detonator with metal shell shell drop stamping drawing process.
Fig. 2 is the left view of structure in a kind of detonator with metal shell shell drop stamping drawing process.
In figure, 1-high-frequency heating power; 2-spiral electromagnetic heating coil; 3-cylindrical metal material; 4-holding pad; 5-cuts off punch; 6-cuts off die; 7-blank guide rail; 8-location-plate; 9-blank mouth; 10-punching stretch punch; 11-stamping cavity die; 12-push rod.
The specific embodiment
Embodiment, with reference to Fig. 1, 2, a kind of detonator with metal shell shell drop stamping drawing process is by high-frequency heating power device, shearing device and detonator shell decompressor three parts form, wherein high-frequency heating power device comprises high-frequency heating power 1, the spiral electromagnetic heating coil 2 being connected with power supply and the cylindrical metal material 3 in coil, shearing device comprises the holding pad 4 that prevents 3 rollings of cylindrical metal material, for cutting off the cut-out die 6 of the cut-out punch 5 of cylindrical metal material 3, blank after cut-out is to the blank guide rail 7 of subsequent processing, detonator shell decompressor comprises that blank slides into blank mouth 97 times through blank guide rail, the location-plate 8 of blank location use, punching stretch punch 10, punching stretch die 11, for supporting the push rod 12 of use.
A kind of method that detonator with metal shell shell drop stamping drawing process is realized is: high-frequency heating power 1 is by heating column metal material 3, cylindrical metal material 3 reaches after punching stretch temperature fast, by conveying device, make cylindrical metal material 3 pass through spiral electromagnetic heating coil 2 with certain speed, cylindrical metal material 3 stretches out after certain length, in order to prevent that cylindrical metal material 3 rolling holding pads 4 from first compressing column metal material 3, cylindrical metal material 3 is cut into blank by cutting off punch 5 with cut-out die 6, blank slides into the blank mouth 9 on die 11 tops of punching stretch by blank guide rail 7, behind 8 pairs of blank location of location-plate, the downward rapid movement of punching stretch punch 10, punching stretch punch 10, under punching stretch die 11 and the common punching stretch effect of push rod 12, complete the disposable punching stretch of blank and become detonator shell, the drop stamping that completes detonator shell stretches and produces whole process.
