A kind of sheet metal forming device is disclosed as China Patent No. " 200520063729.X ", its open day is on November 08th, 2006, its technical scheme is that described sheet metal forming device comprises mould and base, mould is made up of die and top board, described top board is provided with hydraulic cylinder, is provided with a container that mucus is housed and is interconnected with hydraulic cylinder, die respectively between hydraulic cylinder and the die; Be provided with the mucus conduit between container and the die; Be provided with the valve that matches with conduit between hydraulic cylinder and the die; Be provided with lifting platform between die and the base; Lifting platform comprises stage body and crane; Die comprise at least two can be along the module of stage body planar slide.But in the actual forming process of metallic plate, owing between die and the top board trickle gap is arranged, this can make the gas pressure in the die reduce, and not only causes shaping speed slow, also will cause the sheet metal forming failure.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that the sheet metal forming device exists in the prior art, a kind of closed sheet metal forming mould is provided, the utility model can seal the inner chamber of die fully, to sheet metal forming the time, can avoid the pressure in the die to reduce, thereby improve shaping efficiency.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of closed sheet metal forming mould comprises mould and base, and mould is made up of die and top board, and top board is provided with hydraulic cylinder, is provided with a container that mucus is housed and is interconnected with hydraulic cylinder, die respectively between hydraulic cylinder and the die; Be provided with the mucus conduit between container and the die; Be provided with the valve that matches with conduit between hydraulic cylinder and the die; Be provided with elevating mechanism between die and the base, it is characterized in that: described die upper end is symmetrically arranged with two grooves, the bottom of described top board is fixedly connected with two joint pins, the length of described joint pin and the degree of depth of groove are suitable, seal the die inner chamber by joint pin and groove fit during to sheet metal forming.
Offer cannelure in the described groove, be provided with sealing ring in the described cannelure, described sealing ring is sheathed on the joint pin during to sheet metal forming.
The quantity of described groove inner seal ring is two.
Adopt advantage of the present utility model to be:
One, the utility model is symmetrically arranged with two grooves in described die upper end, be fixedly connected with two joint pins in the bottom of described top board, during to sheet metal forming, die uses upwards elevating mechanism that pressing plate moves, joint pin contacts die prior to top board, and in the die on the insertion die, closely cooperating of groove and joint pin can prevent well that the gas pressure in the die inner chamber from reducing, the Forming Quality that is conducive to improve the shaping speed of metallic plate and improves metallic plate.
Two, in the utility model, offer cannelure in the described groove, be provided with sealing ring in the described cannelure, described sealing ring is sheathed on the joint pin during to sheet metal forming, during to sheet metal forming, said structure makes the combination between die and the top board tightr, and the gap between top board and the die is further sealed, and can prevent effectively that the gas pressure in the die from descending.
Three, in the utility model, the quantity of described groove inner seal ring is set to two, and dual-seal is carried out in the junction of die and top board, and sealing effectiveness is better, further improves shaping efficiency and the Forming Quality of metallic plate.
