Background technology
In the middle of existing watchcase blank production technology, be accustomed to by the traditional operation of existing technique, the sheet material of processing linear type blanking, the sheet material that can't tackle the special size specification, the residue corner is larger, cause very large waste,, for the problems referred to above, the invention provides a kind of new punch machining process, because the blanking procedure number of times reduces, cost is low, enhances productivity; Improve stock utilization, reduced leftover bits,, because the watchcase material price is expensive, can produce good economic benefit.
Summary of the invention
The problems referred to above for existing watchcase blank production technology of the present invention, provide a kind of processing method for stamping of circumference type, excavates former material potentiality, can take full advantage of the raw material of special requirement, reduces the generation of leftover bits, the raising stock utilization.
Production process equipment of the present invention includes fixed station gap-framepress, closed type single point press, blanking die, perforating die, the epimorph that falls, presser feet mould, middle temperature type resistance furnace, 0-125 slide measure.
Rapidoprint in production technology of the present invention comprises that 0Cr18Ni9 series stainless steel, H62 series brass, aluminium alloy, titanium alloy, precious metal alloys, engineering plastics etc. are fit to stamping forming stripe shape board-like material.
Production technology of the present invention comprises following operation, blanking procedure, punching operation, the profile that falls operation and presser feet operation.
Blanking procedure is produced required strip boards to watchcase, with forcing press and blanking die, plate shears is cut into the piece material of the dimensions of setting.
The punching operation, the piece material of blanking procedure preparation, is heated to the temperature of setting at middle temperature type resistance furnace, process the endoporus of watchcase blank with forcing press and perforating die.Traditional punching technology, adopt the linear pattern fabrication design, as shown in Figure 1, adopt linear pattern arranged watchcase blank stamping position, blank 1 and blank 2 are arranged side by side, and the piece material is placed on the perforating die location-plate, first stamping strip 1, then horizontally rotate 180 ° of angles, stamping strip 2, may stay larger corner for some special requirement sheet materials.The invention is characterized in, adopt the arranged of circumference type, as shown in Figure 2, blank 1, blank 3 are vertical, and blank 2, blank 4 are horizontal, and blank (1), blank (3) diagonal angle are arranged, blank (1), blank (2) are arranged in juxtaposition, and four watchcase blanks are end to end round layout.
The profile that falls operation, the piece material of punching technology operation preparation, is heated to the temperature of setting in middle temperature type resistance furnace,, by punch and the Internal hole positioning of the epimorph that falls, shear lower watchcase blank.
The presser feet operation, the watchcase blank of the profile operation preparation that falls, is pressed into the pin brilliance degree watchcase blank close with the finished product watchcase with closed type single point press.
Technological design of the present invention is reasonable, can avoid in the middle of watchcase processing reducing the generation of leftover bits for the abandoning of special requirement sheet material, and improves stock utilization, because the watchcase material price is expensive, thereby has produced good economic benefit.

The specific embodiment
Below produce medium-sized serial watchcase blank as example provides the specific embodiment of the present invention take the 0Cr18Ni9 series stainless steel, be used for that the present invention is described further.
Production process equipment of the present invention includes J31-80 forcing press, J21-80 forcing press, J31-160 closed type single point press, blanking die, perforating die, the epimorph that falls, presser feet mould, middle temperature type resistance furnace, 0-125 slide measure.
The rapidoprint of production technology of the present invention comprises the 0Cr18Ni9 series stainless steel, and two kinds of specifications are arranged usually, and specification 1 is the corrosion resistant plate of 75*1000mm, and specification 2 is the corrosion resistant plate of 79*1000mm.
Production technology of the present invention comprises following operation, blanking procedure, punching operation, the profile that falls operation and presser feet operation.
In the middle of blanking procedure, watchcase is produced required strip boards raw material, with J31-80 forcing press and blanking die, size according to art designs, raw material sheet material is cut into the piece material,, for the sheet material of specification 1 size, cut out length 49mm, form 1 block of material of specification of length and width 75*49mm, for the sheet material of specification 2 sizes, cut out length 86mm, form 2 blocks of material of specification of 86*79mm.
Punching technology, the piece material of blanking procedure preparation, is heated to the temperature of 460 ~ 480 ℃ in middle temperature type resistance furnace, be put on the perforating die location-plate, with the J21-80 forcing press, perforating die is installed and is carried out punching.Traditional punching technology, adopt the linear pattern manufacturing procedure,, for 1 block of material of specification, as shown in Figure 1, adopt linear pattern arranged watchcase blank stamping position, blank 1 and blank 2 are arranged side by side, the piece material is placed on the perforating die location-plate, and first stamping strip 1, then horizontally rotate 180 ° of angles, stamping strip 2, can stay larger corner for 2 blocks of material of specification.The invention is characterized in, adopt the arranged of circumference type for 2 blocks of material of specification, as shown in Figure 2, blank 1, blank 3 are vertically arranged, blank 2, blank 4 lateral arrangement are placed on 2 blocks of material of specification on the perforating die location-plate, successively processing; Perhaps first stamping strip 1, then horizontally rotate 180 ° of angles, and stamping strip 3 horizontally rotates 90 ° of angles to the piece material, and stamping strip 2. rotates 180 ° of angles, stamping strip 4. again
