Abstract
The utility model provides a safety bolt which is used for fixing a swaging core of a die and is capable of effectively relieving impact force borne by the swaging core when the swaging core overturns, eliminating impact of the self weight of the swaging core on the lateral pin surface and having a cushioning function and reducing impact force during the return stroke of the swaging core. The safety bolt comprises a screw and is characterized in that a positioning part protruding out of the lateral side of the body of the screw is arranged on the screw, a nut is screwed on each of the two sides of the positioning part and on the screw body, an elastic block is sleeved on the screw body and between the two nuts, and the elastic block can move freely along the screw. The safety bolt has the advantages of being simple in manufacturing technology, long in service life, low in maintaining cost, capable of effectively reducing the impact force borne by the swaging core when the swaging core overturns and during the return stroke of the swaging core, and good in practicality.
Description
Technical field
The utility model relates to a kind of breaker bolt that is applied in the mould.
Background technology
Along with China's automobile industry and other industrial expansion, the die industry of China also makes rapid progress, and in actual production and work, the binder core of many large molds such as automobile die is fixed on the patrix by breaker bolt.Because the binder core is loaded on patrix usually, thereby needs upset, the side pin is stressed during upset; Often upset is very big to binder core and the impact of side pin bearing plane, and the possibility of damaging binder core, side pin-and-hole and bearing plane is arranged.Traditional breaker bolt is generally by screw rod, and nut and sleeve are formed, and this kind breaker bolt does not have the impulsive force of offside pin bearing plane to play cushioning effect.
Summary of the invention
The purpose of this utility model is to propose a kind of breaker bolt, be used for the binder core of fixed mould, can effectively solve the impulsive force that is subjected in the switching process of binder core, and eliminate the impact that the binder core causes because of deadweight offside pin face, and when the backhaul of binder core, play cushioning effect, reduce impulsive force.
Breaker bolt of the present utility model comprises screw rod, key is that described screw rod is provided with the location division that protrudes from screw rod shaft side, described screw rod respectively is rotary with a nut on the shaft of both sides, location division, be with an elastomer block on the shaft between described two nuts, described elastomer block can move freely along screw rod.
In use, screw rod is passed binder core and upper bolster, and utilize location division and a nut to be fixed on the upper bolster screw rod, elastomer block is sandwiched in the middle of another nut and the binder core simultaneously, but the elastomer block between is moved freely.The length of screw rod can design according to the stroke of binder core, guarantee the binder core can freely-movable and binder core stroke on earth the time screw rod and binder core do not have interference.Because binder core place contacts with elastomer block, elastomer block plays cushioning effect during the upset of binder core, effectively decomposes the suffered gravity of binder core side pin, reduces the possibility of binder core, the damage of side pin.
Further, described elastomer block is made of the elastic core element in the middle of the hard gasket at two ends and the pad, can be with the pressure mean transferred of binder core to elastic core element by hard gasket, thus improve buffering effect.
Further, the elastic core element of described elastomer block is that polyurethane is made.Polyurethane has characteristics such as high strength, high abrasion and anti-solvent, is very suitable for the working environment of mould.
Further, described location division is nut, and the position of location division just can be adjusted according to actual needs like this, makes the use of breaker bolt convenient.
Further, an end of described screw rod also welds a safety cover plate, and this side can be used for fixedly binder core, deviates from the nut of avoiding this side, improves security.
Characteristics such as breaker bolt of the present utility model has that manufacturing process is simple, long service life, maintenance cost are low, can effectively reduce the binder core turn over backhaul in the impulsive force that is subjected to, have good practicability.
Description of drawings
Fig. 1 is the structural representation of breaker bolt of the present utility model.
Fig. 2 is the use view of breaker bolt of the present utility model.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, the breaker bolt of present embodiment comprises screw rod 1, key is that described screw rod 1 is provided with the location division 2 that protrudes from screw rod 1 shaft side, described screw rod 1 is rotary with first nut 3 and second nut 4 respectively on the shaft of 2 both sides, location division, be with an elastomer block on the shaft between first nut 3 and second nut 4, described elastomer block can move freely along screw rod 1.Specifically, elastomer block is made of the hard gasket at two ends and the elastic core element 6 in the middle of the pad 5, and elastic core element 6 is made for polyurethane.Can be with the pressure mean transferred of binder core to elastic core element 6 by hard gasket 5, thus buffering effect improved.
Screw rod 1 also welds a safety cover plate 7 at an end of second nut 4, and this side can be used for fixedly binder core, deviates from second nut 4 of avoiding this side, improves security.
As shown in Figure 2, in use, screw rod 1 is passed binder core 8 and upper bolster 9, and utilize location division 2 and first nut 3 to be fixed on the upper bolster 9 screw rod 1, simultaneously elastomer block is sandwiched in the middle of second nut 4 and the binder core 8, but the elastomer block between is moved freely.The length of screw rod 1 can design according to the stroke of binder core 8, guarantee binder core 8 can freely-movables and binder core 8 strokes on earth the time screw rod 1 do not have with binder core 8 and interfere.Because binder core 8 bottoms contact with elastomer block, elastomer block plays cushioning effect during 8 upsets of binder core, effectively decomposes the suffered gravity of binder core 8 side pins, reduces the possibility of binder core 8, the damage of side pin.
Claims (5)
