Description
Technical field
The present invention relates to a kind of watchcase blank production technology, belong to wrist-watch technical field of producing.
Background technology
In the middle of existing watchcase blank production technology, traditional operation by existing technique is accustomed to, the sheet material of processing linear type blanking, cannot tackle the sheet material of special size specification, and 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 blanking procedure number of times reduces, cost is low, enhances productivity; Improve stock utilization, reduce leftover bits, because watchcase material price is expensive, can good economic benefit be produced.
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, excavate former material potentiality, can make full use of the raw material of special requirement, reduce the generation of leftover bits, improve stock utilization.
Production process equipment of the present invention include 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 measures.
Rapidoprint in production technology of the present invention comprises
0cr
18ni
9series stainless steel, H
62series brass, aluminium alloy, titanium alloy, precious metal alloys, engineering plastics etc. are applicable 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 watchcase is produced needed for strip boards, with forcing press and blanking die, plate shears is cut into the block material of the dimensions of setting.
The block material that punching operation prepares blanking procedure, is heated to the temperature of setting, processes the endoporus of watchcase blank with forcing press and perforating die at middle temperature type resistance furnace.Traditional punching technology, adopt linear pattern fabrication design, as shown in Figure 1, adopt linear pattern to arrange watchcase blank stamping position, the first blank 1 and the second blank 2 side by side, are placed on block material on perforating die location-plate, first punching press first blank 1, then horizontally rotate 180 ° of angles, punching press second blank 2, larger corner may be left for some special requirement sheet materials.The invention is characterized in, adopt the arranged of circumference type, as shown in Figure 2, first blank 1, the 3rd blank 3 are longitudinally, second blank 2, the 4th blank 4 are laterally, first blank 1, the 3rd blank 3 diagonal angle are arranged, the first blank 1, second blank 2 is arranged in juxtaposition, and four watchcase blanks are end to end round layout.
The block material that the profile that falls operation prepares punching technology operation, 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, shears lower watchcase blank.
The watchcase blank that presser feet operation prepares the profile operation that falls, is pressed into the pin brilliance degree watchcase blank close with finished product watchcase with closed type single point press.
Present invention process is reasonable in design, watchcase can be avoided to process central abandoning for special requirement sheet material, reduce the generation of leftover bits, improve stock utilization, because watchcase material price is expensive, thus create good economic benefit.

9it is that example provides the specific embodiment of the present invention that series stainless steel produces medium-sized serial watchcase blank, is used for that the present invention is described further.
Production process equipment of the present invention include J31 ?80 forcing presses, J21 ?80 forcing presses, J31 ?160 closed type single point presses, blanking die, perforating die, the epimorph that falls, presser feet mould, middle temperature type resistance furnace, 0 ?125 slide measures.
The rapidoprint of production technology of the present invention comprises

9series stainless steel, has two kinds of specifications 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.
Strip boards raw material needed for watchcase being produced in the middle of blanking procedure, with J31 ?80 forcing presses and blanking die, according to the size of Technology design, raw material sheet material is cut into block material, for the sheet material of specification 1 size, cuts out length 49mm, form the specification 1 block material of length and width 75*49mm, for the sheet material of specification 2 size, cut out length 86mm, form the specification 2 blocks material of 86*79mm.
The block material that punching technology prepares blanking procedure, is heated to the temperature of 460 ~ 480 DEG C in middle temperature type resistance furnace, is put on perforating die location-plate, with J21 ?80 forcing presses install perforating dies carry out punching.Traditional punching technology, adopt linear pattern manufacturing procedure, for specification 1 block material, as shown in Figure 1, linear pattern is adopted to arrange watchcase blank stamping position, first blank 1 and the second blank 2 arranged side by side, block material is placed on perforating die location-plate, and first punching press first blank 1, then horizontally rotates 180 ° of angles, punching press second blank 2, can leave larger corner for specification 2 blocks of material.The invention is characterized in, specification 2 blocks material is adopted to the arranged of circumference type, as shown in Figure 2, the first blank 1, the 3rd blank 3 are longitudinally arranged, the second blank 2, the 4th blank 4 lateral arrangement, be placed on specification 2 blocks of material on perforating die location-plate, process successively; Or first punching press first blank 1, then horizontally rotates 180 ° of angles, punching press the 3rd blank 3, horizontally rotates 90 ° of angles block material, and punching press second blank 2. rotates rotation 180 ° of angles again, punching press the 4th blank 4.
The block material that the profile that falls operation prepares punching operation, is heated to the temperature of 460 ~ 480 DEG C in middle temperature type resistance furnace, is put on epimorph location-plate, by punch and the Internal hole positioning of the epimorph that falls, shears lower watchcase blank.
