Description

Double-layer double-cavity internal high-pressure forming die

Technical Field

The utility model belongs to the mechanical equipment field, concretely relates to interior high pressure forming die

Background

In the prior art, an internal high-pressure die consists of a horizontal oil cylinder, upper and lower die base plates, a die body, end enclosure assemblies and oil circuit systems, wherein the upper and lower base plates need to be enlarged if two sets of products are output simultaneously, the two sets of die bodies are horizontally arranged on the upper surface, and the two sets of die bodies respectively comprise two independent oil circuit systems, two sets of axial horizontal cylinder bodies and two sets of end enclosure assemblies. The disadvantages of this solution are particularly evident, in particular in the following respects:

1. the width of the horizontal direction of the die can be lengthened, the pressure required by the whole press machine needs to be doubled to meet the requirement, and for example, 3000T is required for a single die, and 6000T pressure is required if the die is made into double cavities according to the traditional form, namely two products are produced at a time.

2. The die is lengthened horizontally, the movable working table of the press machine is required to be widened, otherwise the requirement cannot be met, and the widening of the working table of the press machine can lead to the increase of the whole occupied area of the press machine. The mechanism of the whole press is widened

3. The energy consumption increases with the increase in tonnage required for a double cavity die press that produces two products at a time according to this conventional form.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a high pressure forming die in double-deck two-chamber improves the work efficiency of press.

The utility model discloses a high pressure forming die in double-deck two-chamber includes, two sets of moulds down, there is middle backing plate between upper cover mould and the lower cover mould, there is the lower bolster lower side of lower cover mould, there is the upper padding plate upper side of upper cover mould, the lower mould lock of lower cover mould attaches on the lower bolster, the last mould of lower cover mould and the lower mould of upper cover mould attach on middle backing plate with all locking, the last mould lock of upper cover mould attaches on the upper padding plate, the upper padding plate is assembled to sitting in the press, there is the top mould hydro-cylinder of balanced jack-up middle backing plate between lower backing plate and the middle backing plate, through the fixed horizontal hydro-cylinder of riser between the upper padding plate at upper cover mould both ends and middle backing plate. And a horizontal oil cylinder is fixed between the lower backing plate and the middle backing plate at the two ends of the lower sleeve die through vertical plates.

The horizontal oil cylinder is embedded in a groove at the end part of the corresponding base plate through the bottom of the oil cylinder vertical plate, the middle of the horizontal oil cylinder is fixed by a key groove, and positioning blocks are arranged at two sides of the horizontal oil cylinder to prop against the horizontal oil cylinder. Wear-resisting baffle is inlayed to hydro-cylinder riser upper end, and the lower surface of baffle top backing plate has the slot with the baffle corresponding position, and in the slot of mould closure back baffle embedding upside backing plate tip, play and resist the lateral force effect that the hydro-cylinder produced.

The working principle (process) of the utility model is as follows: after the die is installed on the press, an upper base plate of the upper sleeve die is locked on a middle seat of the press through a T-shaped groove, the middle base plate is jacked up by a jacking die oil cylinder along with the upward upper die of the middle seat of the press being opened to an upper limit point of the press, and the upper sleeve die and the lower sleeve die are both in a completely opened state at the moment. The cavities of the upper and lower molds are revealed.

Taking out two pipe fitting products of the previous working procedure, respectively placing the two pipe fitting products into die cavities of an upper die and a lower die, starting a press, driving an oil circuit system of the press to enable an intermediate base plate to move downwards, simultaneously enabling a top die oil cylinder on the press to move downwards, enabling the upper die and the lower die to be completely closed, driving a head sealing assembly to move inwards by a left axial horizontal cylinder and a right axial horizontal cylinder, sealing the pipe fittings, then pressurizing the pipe fittings by a pressurizing device through a high-pressure hole on the head sealing assembly, wherein the pressurizing device always keeps set pressure during pressurizing, the pressurizing device is vertically overlapped, so that the upward pressure generated by the internal pressure of the pipe fittings of the lower die and the downward pressure generated by the pipe fittings of the upper die are offset, the pressure required by the whole die is only the upward pressure generated by the internal pressure of one pipe fitting, after the high pressure reaches the preset requirement of a program, the pressurizing device, the left and right axial cylinders move backwards under the drive of the oil pressure system, the middle seat of the press moves upwards to drive the upper die of the upper sleeve die to move upwards, the top die oil cylinder jacks upwards to jack the middle cushion plate to a certain height, the lower sleeve die opens the die, and a workpiece in the die is taken out.

The utility model has the advantages that: a new internal high pressure die structure is provided, theoretically more layers of dies can be stacked according to the size of the workpiece and the opening and closing distance of the press, and only a double-layer die is taken as an example. Can improve the production efficiency and can produce two products under the condition of the same energy consumption of the press as one workpiece. Meanwhile, the width direction of the die does not need to be widened, so that the size of the whole press machine does not need to be increased. Meanwhile, the allowance of the opening and closing distance in the height direction of the press is well utilized. Two products can be produced at one time, but the tonnage of the press is not increased, the energy consumption is not increased, and the size of the press is not increased.
