Abstract
The present invention relates to the shaping technology of steel cylinder lower head plate, it uses circular plate material as blank, which is calendered under oil press to pass through calendering mould to form lower head plate work piece, after demould, the work piece is directly sent to opening shrinking machine to proceed shrinking processing, it omits the process of edge pressing and flanging, but can satisfy the requirement of butt welding of upper and lower head plates. Its simplifies the shaping technology, saves raw material and raises the prodn. efficiency.
Description
The present invention relates to the low head moulding process that steel cylinder is produced.
At present, in the steel cylinder production process, the upper cover of moulding and low head butt joint are welded into a steel cylinder integral body.And the moulding of low head and reducing are one of critical processes of whole steel cylinder global formation, traditional technology is such: plectane is rolled into the low head semi-finished product, the port that leaves the flanging bead, has that these semi-finished product have is not neat, then, carry out reducing processing (as shown in Figure 1) again with low head port edging machining.The shortcoming of this technology is: 1. must reserve certain surplus during plectane calendering formation low head, form edge and neat mouthful of processing with operation after an action of the bowels, cause the waste of material; 2. neat mouthful processing takies labor and materials such as effective working, consumes energy and tool holder; 3. operation is many, continuous clamping location, discharging, inefficiency.
The objective of the invention is for overcoming the deficiencies in the prior art part, propose a kind of moulding necking down process of saving material, improving the steel cylinder low head of working (machining) efficiency.
The objective of the invention is to be achieved through the following technical solutions: the moulding necking down process of steel cylinder low head, special feature is with the blank of circular sheet material as the low head moulding, circular sheet material is placed on the hydraulic press by the level and smooth low head workpiece of calendering mould calendering formation port perisporium, directly send into after the workpiece demoulding and carry out reducing processing on the necking machine, the low head after the reducing can satisfy the requirement of docking welding with upper cover.
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is traditional process chart;
Fig. 2 is the schematic diagram of blank;
Fig. 3 is the structural representation of calendering formation;
Fig. 4 is the schematic diagram of low head workpiece;
Fig. 5 is the structural representation of reducing processing;
Fig. 6 is the schematic diagram of low head finished product.
Referring to Fig. 2-6, low head with the 15Kg liquefied petroleum gas steel cylinder is an example below, earlier the sheet material of strip and block is gone out circular slab material 1 (as shown in Figure 2) on hydraulic press, with this blank as the low head moulding, then circular sheet material 1 is put on the hydraulic press and carries out moulding (as shown in Figure 3) by the calendering mould, the punch 2 downward punching presses of calendering mould, make circular sheet material blank tightly encase punch 2, and together pass die 3 and enter die packing ring 4, and the adjoiner of die 3 and die packing ring 4 has groove 5, be embedded with spring 6 and material returned slide block 7 in the groove 5, after low head workpiece 8 and punch 2 entered die packing ring 4 fully, material returned slide block 7 radially was pressed on punch 2 outer surfaces under the elastic force effect of spring 6, when backhaul is walked in punch 2 risings, material returned slide block 7 just in time stops the stroke of low head workpiece 8, and workpiece is scraped and the demoulding.Though the surplus limit of lower seal workpiece 8 ports after the demoulding is irregular, perisporium level and smooth (as shown in Figure 4).Directly put into necking machine after 8 demouldings of low head workpiece and carry out reducing processing (as shown in Figure 5), low head workpiece 8 is compressed by the hold down gag 9 of necking machine and covers on the location tire swelling device 10, location tire swelling device 10 is by main shaft 11 driven rotary, the interior hobboing cutter 12 of reducing of being located at side clamps low head workpiece 8 from inwall under hydraulic jack drives, 13 on the outer hobboing cutter of reducing utilizes pressure that the port of low head workpiece 8 is dwindled from outer wall feeding extruding.Low head finished product (as shown in Figure 6) after reducing is finished can satisfy the requirement of docking welding with upper cover, and need not edging.
The present invention has cancelled traditional flanging bead and neat mouthful operation, directly to workpiece necking forming with surplus limit, make the circular sheet material blank diameter of low head moulding can reduce 1%, but mouth cuts economical with materials 2.3% together, economic benefit is fairly obvious, and simplified processing technology, improved production efficiency.
Claims (1)
1, the moulding necking down process of steel cylinder low head, it is characterized in that: with the blank of circular sheet material as the low head moulding, circular sheet material is placed on the hydraulic press by the level and smooth low head workpiece of calendering mould calendering formation port perisporium, directly send into after the workpiece demoulding and carry out reducing processing on the necking machine, the low head after the reducing can satisfy the requirement of docking welding with upper cover.
