Description
Technical field
The utility model relates to the special-purpose fast-assembling punching die of a kind of plastic tensile grate, is mainly used in the punch process of plastic tensile GSZ production process.
Background technology
The plastic tensile GSZ is an indispensable reinforcement reinforcement material during present geotechnological material engineering is built, and at first the plastic plate punching of extruding, carries out then vertically, cross directional stretch obtains in its production process.Many in the punch process owing to making a spurt; Velocity ratio is higher, is easy to occur the phenomenon of disconnected jumper bar, disconnected spring, and if these glitch will cause shutdown completely; Fault is little; But lose very greatly,, shut down start process at every turn and all can cause a lot of losses due to spoiled work because production line is very long.
Present punch die structure is a lot, all is integral installation generally, though the making precision is very high, it is impossible that the situation of disconnected jumper bar or disconnected spring is avoided fully.General present mould structure if change jumper bar or spring, all must all be taken the negative template of entire die, material returned stool apart; So very time-consuming; And installation is also pretty troublesome, and jumper bar of general replacement or spring are all wanted seven or eight hours consuming time, if producer does not have the mould worker of specialty; The thing that also causes mould and die accuracy to guarantee easily takes place, and the life-span of mould is reduced greatly.
The utility model content
The purpose of the utility model is exactly to provide a kind of plastic tensile grate special-purpose fast-assembling punching die for fear of the prior art deficiency; It can change jumper bar or spring fast; And need not to take apart mould, and saved the time greatly, guaranteed that also mould and die accuracy is unaffected.
The technical scheme that the utility model solves the problems of the technologies described above is following: the special-purpose fast-assembling punching die of a kind of plastic tensile grate; Comprise upper mould fixed plate, counterdie fixed head, force plate, negative template, stripper, jumper bar and spring; Said upper mould fixed plate is installed in the top of said counterdie fixed head, and said negative template is installed in said counterdie fixed head upside, and said force plate is installed in said upper mould fixed plate downside; And said force plate is positioned at the top of said negative template; Said stripper is between said force plate and said negative template, and said spring one end is connected with said stripper, and the other end is connected with said upper mould fixed plate; Said upper mould fixed plate middle part offers the groove of up/down perforation; Be provided with the jumper bar fixed block in the said groove, said jumper bar bottom of fixed is connected with the top of said jumper bar, thereby said jumper bar is installed in the downside of said upper mould fixed plate.
Adopt the beneficial effect of technique scheme to be; The special-purpose fast-assembling punching die of the utility model plastic tensile grate is installed the jumper bar fixed block through offer the groove of up/down perforation at the upper mould fixed plate middle part in groove, connect jumper bar through the jumper bar fixed block again; Changed the integral mold plate structure that existing general punching die jumper bar is fixedly connected with upper mould fixed plate; Only need the jumper bar fixed block is just disassembled and can directly change jumper bar, need not form removal tool miscellaneous part, can change jumper bar fast; Time saving and energy saving, guaranteed that mould and die accuracy is unaffected.
On the basis of adopting technique scheme, the utility model can also carry out following further improvement.
Further, said groove is the T type structure that open upper end is big, lower ending opening is little, and said jumper bar fixed block is the T type structure that is complementary with said groove structure.
Adopt the beneficial effect of above-mentioned further technical scheme to be, boss of the inner formation of the groove of T type structure, the jumper bar fixed block of T type structure can place the lug boss position place in the groove just.
On the basis of adopting technique scheme, the utility model can also carry out following further improvement.
Further; Offer the spring fixed hole of up/down perforation on the said upper mould fixed plate; Through the lead screw that has been threaded, the end that said spring is connected with said upper mould fixed plate places in the said spring fixed hole, and said spring is positioned at the below of said lead screw in the said spring fixed hole.
Adopt the beneficial effect of above-mentioned further technical scheme to be, the special-purpose fast-assembling punching die of the utility model plastic tensile grate has changed the connected mode of upper mould fixed plate and spring in the existing punching die, through the spring fixed hole on the upper mould fixed plate is got through; And on the wall screw thread is set within it, through the lead screw that is threaded, and an end that makes spring be connected with upper mould fixed plate places in this spring fixed hole; And be located at the below of lead screw; Like this, spring just is stuck between lead screw and the stripper, can adjust the tightness of spring through the set screw bar; Simultaneously, can also change spring easily.
The beneficial effect of the utility model is that the special-purpose fast-assembling punching die of the utility model plastic tensile grate is simple in structure, easy to maintenance, can change jumper bar or spring fast, need not to take apart mould, and is time saving and energy saving, guaranteed that mould and die accuracy is unaffected.
Description of drawings
Fig. 1 is the structural representation of the special-purpose fast-assembling punching die of the utility model plastic tensile grate.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1, the special-purpose fast-assembling punching die of a kind of plastic tensile grate comprises upper mould fixed plate 1, counterdie fixed head 2, force plate 3, negative template 4, stripper 5, jumper bar 6 and spring 7; Connect through big guide pillar 11 between upper mould fixed plate 1 and the counterdie fixed head 2, upper mould fixed plate 1 is positioned at the top of counterdie fixed head 2, and negative template 4 is installed in counterdie fixed head 2 upsides; Force plate 3 is installed in upper mould fixed plate 1 downside; And force plate 3 is positioned at the top of negative template 4, and stripper 5 is between force plate 3 and negative template 4, and upper mould fixed plate 1 downside is fixed with stripper set bolt 12; Stripper set bolt 12 tops are connected on the upper mould fixed plate 1; The other end is connected with stripper 5, and spring 7 one ends are connected with stripper 5, and the other end is connected with upper mould fixed plate 1; The downside of upper mould fixed plate 1 also is fixed with stripper guide pillar 13; Stripper 5 is provided with and the corresponding guide groove 50 in stripper guide pillar 13 positions, and stripper guide pillar 13 is arranged in the guide groove 50, thereby makes stripper 5 to move up and down along stripper guide pillar 13.Upper mould fixed plate 1 middle part offers the groove 101 of up/down perforation, is provided with jumper bar fixed block 8 in the groove 101, and jumper bar fixed bar 8 bottoms are connected with the top of jumper bar 6, thereby jumper bar 6 is installed in the downside of upper mould fixed plate 1.The special-purpose fast-assembling punching die of the utility model plastic tensile grate is through offering the groove 101 of up/down perforation at upper mould fixed plate 1 middle part; Jumper bar fixed block 8 is installed in groove 101; Connect jumper bar 6 through jumper bar fixed block 8 again, changed the integral mold plate structure that existing general punching die jumper bar is fixedly connected with upper mould fixed plate, only need jumper bar fixed block 8 just be disassembled and directly to change jumper bar 6; Need not form removal tool miscellaneous part; Can change jumper bar 6 fast, time saving and energy saving, guaranteed that mould and die accuracy is unaffected.
