Abstract
The invention discloses a bolt fastening structure of a pipe die. The bolt fastening structure of the pipe die comprises a mounting hole arranged in an upper die, a screw hole arranged in a lower die and a bolt which is inserted in the mounting hole and can be in threaded connection with the screw hole, and is characterized in that an outer spring clamp is arranged on the bolt, an inner spring clamp is arranged in the mounting hole, a spring is sleeved on the bolt between the outer spring clamp and the inner spring clamp, and a bolt end socket is arranged at the mounting hole; when opening a mold, no damage can be caused to screw threads during the form removal; and during the die assembly, the upper die and the lower die are aligned and a bolt is screwed on, the operation is convenient, and assembling efficiency is high.
Description
Technical field
The present invention relates to a kind of syndeton of pipe die, the particularly a kind of patrix of pipe die and bolt fastening structure of counterdie of connecting.
Background technology
Need behind the mould matched moulds of cement pipe pile for construction to connect with bolt, traditional bolt fastening structure of pipe die is that attachment bolt is contained in below the pipe die, tightens behind the patrix that overturns then.There is above shortcoming in this syndeton: expense is artificial, flips up easily screw thread is made a mess of, and causes the damage of bolt, and adopts the efficiency of assembling of this syndeton lower.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of installation effectiveness height and can prevent to damage the bolt fastening structure of pipe die of bolt.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of bolt fastening structure of pipe die, comprise the installing hole that is arranged in the patrix, the bolt that is arranged on the screw in the counterdie and interts in installing hole and can be threaded with screw, it is characterized in that being equipped with on the described bolt outer spring card, the inner spring card is installed in the installing hole, be set with spring on the bolt between outer spring card and the inner spring card, described installing hole place is equipped with the bolt end socket.
Preferred embodiment a kind of as the utility model, described bolt end socket is installed in the installing hole; Be threaded between described bolt end socket and the installing hole.
Preferred embodiment a kind of as the utility model, described bolt end socket is installed on the patrix at installing hole place; Be threaded between described bolt end socket and the patrix.
The invention has the beneficial effects as follows: after the upper die and lower die of pipe die were taken apart, the bolt of this bolt fastening structure was suspended on the patrix by bolt end socket and outer spring card, and the screw thread of bolt is positioned at patrix, can not cause damage by double thread after the form removal; During matched moulds upper die and lower die are aimed at the bolt of screwing on and get final product, easy to operate, the efficiency of assembling height.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of first kind of embodiment of the present invention;
Fig. 2 is the structural representation of first kind of embodiment of the present invention.
The specific embodiment
With reference to Fig. 1, Fig. 1 is the structural representation of one embodiment of the present invention, in embodiment as shown in the figure, this bolt fastening structure of pipe die, comprise the installing hole 2 that is arranged in the patrix 1, the bolt 5 that is arranged on the screw 4 in the counterdie 3 and interts in installing hole 2 and can be threaded with screw 4, outer spring card 6 wherein is installed on bolt 5, inner spring card 7 is installed in the installing hole 2, be set with spring 8 on the bolt 5 between outer spring card 6 and the inner spring card 7, bolt end socket 9 is installed in installing hole 2, can adopt between bolt end socket 9 and the installing hole 2 to be threaded, so that change bolt.
After the upper die and lower die of pipe die are taken apart, spring push outer spring card, the outer spring card contacts with the bolt end socket, and the bolt of this bolt fastening structure is suspended on the patrix by bolt end socket and outer spring card, and the screw thread of bolt is positioned at patrix, can not cause damage by double thread after the form removal; During matched moulds upper die and lower die are aimed at the bolt of screwing on and get final product, easy to operate, the efficiency of assembling height.
With reference to Fig. 2, Fig. 2 is the structural representation of another embodiment of the present invention, and this embodiment and above-mentioned embodiment are basic identical, and difference is that bolt end socket 9 is installed on the patrix 1 at installing hole 2 places, is threaded between bolt end socket 9 and the patrix 1.
