Abstract

The invention relates to a quick replacing device for large tools and moulds. An upper connecting block is in tight contact with a lower connecting block, the lower connecting block is connected with a mould connecting head, pins are inserted in pin holes of the lower connecting bock, the pins are in hinged joint with connecting rods, supporting cylinders are installed on the upper portions of the connecting rods, gaskets are connected to the connecting rods in a sleeving mode, springs are pressed on the gaskets and located in the supporting cylinders, and nuts are connected with the tail ends of the connecting rods. When a mould is replaced, the nuts are loosened, the supporting cylinders pop up under the action of the springs, the bottom end faces of the supporting cylinders are disengaged from the upper connecting block, then the connecting rods are rotated to enable the supporting cylinders to be horizontally arranged, at the moment, the upper connecting block can be moved away, and the mould can be taken out and replaced; after the mould is replaced, the upper connecting block is put on the lower connecting block, the connecting rods are restored, the nuts are fastened, the springs are pressed, the bottom end faces of the supporting cylinders are tightly pressed on the upper connecting block, the mould and the mould connecting head are tightly clamped and connected together through the upper connecting block and the lower connecting block, the upper connecting block and the lower connecting block cannot be separated, the purpose of quickly replacing the mould is achieved, and the quick replacing device has the advantages of being simple and easy to achieve.

Description

A kind of large-scale tool and mould quick replacement device

Technical field

The invention belongs to oil and gas pipes test equipment field, particularly the large-scale tool and mould quick replacement device of one.

Background technology

In recent years along with expanding economy, energy demand sharp increase, international, domestic all in the dynamics strengthening recover petroleum, natural gas.Pipe-line obtains develop rapidly as a kind of economy of oil and natural gas, long distance delivery instrument safely, uninterruptedly.In order to meet oil gas high-pressure delivery, before oil and gas pipes dispatches from the factory, hydraulic pressure test must be carried out.Due to the difference of caliber, when hydraulic pressure test usually according to the continuous more mold exchange of the needs of order, more mold exchange all needs to pull down locking device at every turn, and very very complicated, has a strong impact on production efficiency, consumes a large amount of manpowers and man-hour.

Summary of the invention

In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of large-scale tool and mould quick replacement device, it can when changing different size mould without the need to all pulling down the locking device of die connecting device, decrease workload, there is the advantage that structure is simple, easy to use, cost is low.

In order to achieve the above object, the technical solution used in the present invention is:

A kind of large-scale tool and mould quick replacement device, comprise contiguous block 2, upper contiguous block 2 and lower connecting block 4 close contact, lower connecting block 4 is connected with mould connector 1, is inserted with pin 10 in the pin-and-hole of lower connecting block 4, hinged and connecting rod 9 can swing around pin 10 with connecting rod 9 for pin 10, connecting rod 9 top is provided with support tube 6, and packing ring 8 is socketed on connecting rod 9, and spring 7 is pressed on packing ring 8, and it is inner to be positioned at support tube 6, nut 5 is connected with connecting rod 9 end passing support tube 6.

The present invention is simple and easy to realize, and more during mold exchange 3, unclamps nut more than 5 circle, under spring 7 acts on, support tube 6 is upspring, and makes support tube 6 bottom face depart from upper contiguous block 2, then swivel link 9 makes support tube 6 horizontal positioned, now goes up contiguous block 2 and just can remove, and mould 3 just can take out and change; After more finishing changing mould 3, upper contiguous block 2 is placed on lower connecting block 4, connecting rod 9 is resetted, fastening nut 9, holddown spring 7, support tube 6 bottom face tightly compresses contiguous block 2, now goes up contiguous block 2 and lower connecting block 4 and is tightly blocked with mould connector 1 by mould 3 and connect together, and upper contiguous block 2 can not be separated with lower connecting block 4, reaches the object of quickly replacing mould.It when changing different size mould without the need to all pulling down the locking device of die connecting device, can decrease workload, having the advantage that structure is simple, easy to use, cost is low.

Fig. 2 is structure side view of the present invention.

Fig. 3 is the amplification connection diagram of each parts of Fig. 2.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described in detail.

With reference to Fig. 1, a kind of large-scale tool and mould quick replacement device, comprises contiguous block 2, upper contiguous block 2 and lower connecting block 4 close contact, and lower connecting block 4 is connected with mould connector 1 by bolt, is fixed together all the time both when more mold exchange; Pin 10 is inserted with in the pin-and-hole of lower connecting block 4, hinged and connecting rod 9 can swing around pin 10 with connecting rod 9 for pin 10, connecting rod 9 top is provided with support tube 6, packing ring 8 is socketed on connecting rod 9, spring 7 is pressed on packing ring 8, and it is inner to be positioned at support tube 6, nut 5 is connected with connecting rod 9 end passing support tube 6.

Operation principle of the present invention is:

First, more during mold exchange 3, rotating nut 5 makes it moves, under spring 7 acts on, support tube 6 is upspring, and support tube 6 bottom face and upper contiguous block 2 are separated by a distance, then swivel link 9 makes support tube 6 horizontal positioned, now goes up contiguous block 2 and just can remove, and mould 3 just can take out and change; After more finishing changing mould 3, upper contiguous block 2 is placed on lower connecting block 4, connecting rod 9 is resetted, fastening nut 5, holddown spring 7, support tube 6 bottom face tightly compresses contiguous block 2, now goes up contiguous block 2 and lower connecting block 4 and is tightly blocked with mould connector 1 by mould 3 and connect together, and upper contiguous block 2 can not be separated with lower connecting block 4, reaches the object of quickly replacing mould.In whole mold exchange 3 process, only need pull down contiguous block 2, simple to operate, more mold exchange is rapid, decreases labour intensity and more mold exchange time.

In accompanying drawing: 1 mould connector; 2 is upper contiguous block; 3 is mould; 4 is lower connecting block; 5 is nut; 6 is support tube; 7 is spring; 8 is packing ring; 9 is connecting rod; 10 is pin.
