Description
本發明是關於一種火藥槍，特別是關於一種方便拆卸的火藥槍。 This invention relates to a gunpowder, and more particularly to a gunpowder that is easily disassembled.
鋼鐵廠為了檢測剛生產出之連鑄胚的凝固程度與凝殼厚度，會使用連鑄胚測厚儀進行檢測。一般而言，檢測方式係利用連鑄胚測厚儀專用之火藥槍將檢測釘體擊打入連鑄胚之胚料中，於鋼胚冷卻後，將胚料之被擊打處切開，觀察檢測釘體與胚料之間的熔融狀況，進而得知連鑄胚當時的凝固程度。由於連鑄胚的厚度達數十公分以上，為了將檢測釘體順利打入胚料中，火藥槍須具有很大的火力。再者，火藥槍須具有足夠的槍膛壁厚，始可負荷火藥殼內之火藥燃燒***的威力，故火藥槍的槍身非常沈重。另外，由於連鑄胚的表面溫度高達數百度甚至上千度，火藥槍須具有足夠的長度，以避免火藥殼距離連鑄胚之胚料太近，而使得火藥被胚料的高溫引燃***。因此，火藥槍須具有足夠的質量及長度，始可負荷火藥殼內之火藥燃燒***的威力，並避免高溫胚料對火藥槍之影響。 In order to detect the degree of solidification and the thickness of the shell of the newly produced continuous casting, the steel plant will use a continuous casting thickness gauge for testing. In general, the detection method is to use the gunpowder gun dedicated to the continuous casting embryo thickness gauge to hit the detection nail into the blank of the continuous casting embryo, and after the steel embryo is cooled, the hitting portion of the blank is cut and observed. The melting condition between the nail body and the billet is detected, and the degree of solidification of the continuous casting embryo at that time is known. Since the thickness of the continuous casting embryo is several tens of centimeters or more, in order to smoothly inject the detecting nail into the blank, the gun must have a large firepower. Moreover, the gunpowder gun must have sufficient wall thickness of the gun to load the explosive power of the gunpowder in the gunpowder shell, so the gun body of the gunpowder gun is very heavy. In addition, since the surface temperature of the continuous casting embryo is as high as several hundred degrees or even thousands of degrees, the gunpowder must have a sufficient length to prevent the gunpowder shell from being too close to the billet of the continuous casting embryo, so that the gunpowder is ignited by the high temperature of the billet. . Therefore, the gunpowder must have sufficient quality and length to load the explosive power of the gunpowder in the gunpowder shell and avoid the impact of the high temperature billet on the gunpowder.
每一次擊發後，須將火藥槍之槍體進行拆卸以 更換火藥殼，方可進行下一次的擊發。習知火藥槍在進行拆卸時，須將火藥槍之上槍管與下槍管相互旋轉，以進行拆裝。然而，上槍管與下槍管的重量總和約十幾公斤重。因此，火藥槍的拆卸過程相當耗費人力及時間。再者，火藥殼會因***的威力而被撐開，甚至變形，進而導致火藥殼之外壁與火藥槍之膛室卡住，而無法進行更換。更甚者，由於作業環境溫度較高，長時間的作業對於操作人員來說是相當大的負擔。 After each firing, the gun body of the gunpowder must be disassembled. Replace the gunpowder shell for the next shot. When the conventional gunpowder is disassembled, the barrel above the gunpowder and the lower barrel must be rotated to disassemble. However, the sum of the weight of the upper barrel and the lower barrel is about ten kilograms. Therefore, the disassembly process of the gunpowder is quite labor intensive and time consuming. Moreover, the gunpowder shell is distracted or even deformed by the power of the explosion, which causes the outer wall of the gunpowder shell to be stuck with the chamber of the gunpowder, and cannot be replaced. What's more, due to the high operating environment temperature, long-term work is a considerable burden on the operator.
有鑑於此，亟須提供一種火藥槍，其係便於進行槍管的拆裝作業，且可避免火藥殼因膨脹變形而不易更換的問題。 In view of this, it is not necessary to provide a gunpowder which facilitates the disassembly and assembly of the barrel and avoids the problem that the powder shell is not easily replaced due to expansion deformation.

在一實施例中，火藥殼180之連接部186係螺接於第三內徑段114c，並抵頂射釘管112之底面。在一實施例中，本體部184係容置於第二內徑段114b中，但本體部184之端面未抵頂於第三內徑段114c，故第三內徑段114c之端面A1與本體部184之間具有第一間隙S1(換言之，第一間隙S1係位於第二內徑段114b之內表面與連接部186之間)。當火藥190燃燒***後，第一間隙S1可避免火藥殼180因膨脹而使本體部184之端面與第三內徑段114c之端面A1迫緊，而使火藥殼180不易拆卸。在另一實施例中，操作部182係容置於第一內徑段114a中，但操作部182之端面未抵頂於第二內徑段114b，故第二內徑段114b之端面A2與操作部182之間具有第二間隙S2(換言之，第二間隙S2係位於第一內徑段114a之內表面與操作部182及部分之本體部184之間)。同樣地，第二間隙S2亦可避免火藥殼180因膨脹而使操作部182之端面與第二內徑段114b之端面A2迫緊，進而導致火藥殼180在火藥190燃燒***後不易拆卸。 In one embodiment, the connection portion 186 of the powder charge shell 180 is threaded to the third inner diameter portion 114c and abuts against the bottom surface of the nail tube 112. In one embodiment, the body portion 184 is received in the second inner diameter portion 114b, but the end surface of the body portion 184 does not abut the third inner diameter portion 114c, so the end surface A1 of the third inner diameter portion 114c and the body There is a first gap S1 between the portions 184 (in other words, the first gap S1 is located between the inner surface of the second inner diameter portion 114b and the connecting portion 186). When the gunpowder 190 is burned and exploded, the first gap S1 can prevent the gunpowder shell 180 from being inflated to tighten the end surface of the body portion 184 and the end surface A1 of the third inner diameter portion 114c, so that the gunpowder shell 180 is not easily disassembled. In another embodiment, the operating portion 182 is received in the first inner diameter segment 114a, but the end surface of the operating portion 182 does not abut the second inner diameter portion 114b, so the end surface A2 of the second inner diameter portion 114b is The operation portion 182 has a second gap S2 therebetween (in other words, the second gap S2 is located between the inner surface of the first inner diameter portion 114a and the operation portion 182 and a portion of the body portion 184). Similarly, the second gap S2 can also prevent the end face of the operating portion 182 and the end surface A2 of the second inner diameter portion 114b from being forced by the expansion of the gunpowder shell 180, thereby causing the gunpowder shell 180 to be difficult to disassemble after the gunpowder 190 is burned and exploded.
在一實施例中，沿著火藥殼180之軸心剖切，操作部182之剖面形狀為非圓形。若操作部182之剖面形狀為圓形，則因無施力點，而使得火藥殼180不易拆卸。在另一實施例中，操作部182為多邊形凸塊或多邊形凹部。由於操作部182之徑向尺寸d1小於第一內徑尺寸D1，故利用對應操作部182之形狀的轉動工具，即可省力地轉動操作部 182，而將連接部186螺出火藥槍100之第三內徑段114c，以自槍管連接套114中取出火藥殼180。因此，更換火藥殼180的過程可較為方便且省時。 In one embodiment, along the axis of the powder shell 180, the cross-sectional shape of the operating portion 182 is non-circular. When the cross-sectional shape of the operation portion 182 is circular, the gunpowder case 180 is hard to be removed because there is no force application point. In another embodiment, the operating portion 182 is a polygonal bump or a polygonal recess. Since the radial dimension d1 of the operating portion 182 is smaller than the first inner diameter dimension D1, the operating portion can be flexibly rotated by using a rotating tool corresponding to the shape of the operating portion 182. 182, the connecting portion 186 is screwed out of the third inner diameter portion 114c of the gunpowder 100 to take out the powder shell 180 from the barrel connecting sleeve 114. Therefore, the process of replacing the gunpowder shell 180 can be more convenient and time-saving.
