Refer to Fig. 1, Fig. 2 and Fig. 3, the forging and stamping system for pipe clamp that the utility model provides comprises heating furnace and stamping machine, and wherein, described heating furnace is electromagnetic induction heating furnace 1, and described stamping machine comprises embryo punch press 2 processed and friction press 3; The outlet of described electromagnetic induction heating furnace 1 is connected with embryo punch press 2 processed, and described embryo punch press 2 processed is connected with molding machine 4 by friction press 3; Described friction press 3 is provided with upper mold half 5 and lower mold half 6, described lower mold half 7 is provided with side by side the first die cavity 7 and the second die cavity 8, described first die cavity 7 is roughly the same with the shape of the second die cavity 8, the size being dimensioned slightly smaller than the second die cavity 8 of described first die cavity 7, described lower mold half 6 is connected with horizontal drive mechanism.
The forging and stamping system for pipe clamp that the utility model provides, wherein, is provided with 45 ° of annular withdrawing pattern lines 10 in described upper mold half 5, be equipped with 75 ° of tapering trimmings 11 in the first die cavity 7 of described lower mold half and the second die cavity 8.Described horizontal drive mechanism can be hydro-cushion cylinder, is provided with hydraulic climbing mechanism 9, as shown in Figure 4 between the upper mold half 5 of described friction press and lower mold half 6; Described hydraulic climbing mechanism 9 is connected with pedal switch (not shown) by interlocking operation mechanism with hydro-cushion cylinder.Hydraulic climbing mechanism 9 can adopt spring hydraulic formula, and at A place under normal condition, change to B place, now die-forging forming at patrix to A place when pressing down, B place hydraulic spring grease cup changes to A place again and ejected by material.For the ease of placing preliminary shaping block, also otch can be set at the X place of counterdie mould.
The forging and stamping system for pipe clamp that the utility model provides, described molding machine is provided with trimming patrix 12 and trimming counterdie 13, as shown in Figure 5.Employing shaving die is last procedure after pipe clamp formed product, excises unnecessary slitter edge exactly.In order to avoid trimming patrix 12 and trimming counterdie 13 directly bond, cause the damage of mould.Symmetrically between described trimming patrix 12 and trimming counterdie 13 be provided with push rod 15 and spring 14, described trimming counterdie 13 is provided with the through hole 16 holding push rod, and described spring 14 is enclosed within push rod 15.If do not have spring, probably in the end a procedure is inadequate due to product temperature, causes trimming patrix, formed product embryo and trimming counterdie directly to bond and blocks, and then mold damage.After using above-mentioned spring spindle, ensured the enough distances of upper and lower mould, both excised product slitter edge, can ensure that again upper and lower mould has third party's active force, namely the elastic force of spring can make upper/lower die separately, also improves production efficiency simultaneously.
The utility model also provides a kind of forging method of the above-mentioned forging and stamping system for pipe clamp, wherein, in turn includes the following steps:
A) first use electromagnetic induction heating furnace 1 pair of round steel blank to heat, form forge hot embryo; The hollow circular cylinder electromagnetic induction coil passed through for round steel blank that length is 1.7 ~ 2.0 meters is provided with in described electromagnetic induction heating furnace 1, the transformer that described hollow circular cylinder electromagnetic induction coil can be 100 ~ 1000Hz with frequency is connected, the electrified regulation time is 8 ~ 15 seconds, forge hot embryo can be controlled by interior Fast Heating outward, reach the tapping temperature of 1100 ~ 1200 DEG C; Substantially reduce the heat time.
B) then utilize embryo punch press processed 2 pairs of forge hot embryos to carry out punching press and form preliminary shaping block; Described embryo punch press 2 processed uses reusable compound die, and by adjusting the stroke of embryo punch press processed, the contact area of compound die counterdie height and drift and compound die counterdie forms the preliminary shaping block varied in size.If adopt traditional mode, so just need a product one set of die, so just greatly increase the cost of embryo mould processed.Embryo mode processed of the present utility model just takes some raw material, has but greatly saved the cost of mold materials.
C) the first die cavity 7 on recycling friction press and the second die cavity 8 carry out twice extruding to preliminary shaping block and form pipe clamp shaping block; Because the first die cavity 7 is roughly the same with the shape of the second die cavity 8, the size being dimensioned slightly smaller than the second die cavity 8 of described first die cavity 7, the first time that first die cavity 7 is used for product as blank mould is shaping, and the second die cavity 8 is as thin mould, and geomery accurately also can arrange logo mark; Two die cavitys are positioned at same mould side by side, decrease the distance of product flowing, and so just greatly save the heat of shaping stock, the time interval of twice extruding is very short, thus effectively reduces product energy consumption, ensure the forging and stamping intensity of pipe clamp.
The upper mold half 5 of described friction press can arrange annular withdrawing pattern line 10, and angle of inclination is preferably 45 °; Can arrange tapering trimming 11 in first die cavity 7 and the second die cavity 8 of lower mold half 6, angle of inclination is preferably 75 °.Annular withdrawing pattern line 10 compares point-like projection, the demoulding of being more convenient for, particularly by annular withdrawing pattern line 10 and tapering trimming 11 with the use of, be easier to the demoulding.In addition, the tapering trimming 11 in the second die cavity 8 can form corresponding tapering trimming inside pipe clamp, is convenient to install mounting flange, prevents the aging posterior synechia of flange on pipe clamp; Particularly employing angle of inclination is the tapering trimming of 75 °, greatly can increase the contact area of pipe clamp and flange, can also prevent burr inside pipe clamp from pricking the hand.
Hydraulic climbing mechanism 9 is provided with between the upper mold half 5 of described friction press and lower mold half 6, described horizontal drive mechanism is hydro-cushion cylinder, described hydraulic climbing mechanism 9 is connected with pedal switch by interlocking operation mechanism with hydro-cushion cylinder, by the demoulding of pedal switch control rule pipe clamp shaping block, and the translation synchronously realizing the first die cavity 7 and the second die cavity 8 switches, and can shorten the time interval of twice extruding further.Workman ejects preliminary shaping block by pedal switch from the first die cavity 7, presss from both sides out the second die cavity 8 that preliminary shaping block puts into side simultaneously and can complete twice extruding and form pipe clamp shaping block, greatly enhance productivity.
D) finally utilize molding machine 4 to excise unnecessary slitter edge, form pipe clamp.
In sum, the forging and stamping system for pipe clamp that the utility model provides, Fast Heating is carried out outward by interior by electromagnetic induction heating furnace 1 pair of round steel blank, utilize the first die cavity 7 on friction press 3 and the second die cavity 8 to carry out twice extruding to preliminary shaping block and form pipe clamp shaping block, thus effectively reduce product energy consumption, greatly promote the forging and stamping intensity of pipe clamp, and can operation be simplified, enhance productivity, whole pipe clamp forge time can control within 10 seconds.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
