Brief description of the drawings
Fig. 1 is the structural representation of hydraulic expanding die machine of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, most preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, hydraulic expanding die machine comprises patrix coupling assembling and counterdie coupling assembling, patrix coupling assembling comprises upper mould fixed plate 1 and patrix lock sleeve 2, patrix lock sleeve 2 connects upper mould fixed plate 1 with screw, counterdie coupling assembling comprises moving clamping plate 14, pull bar 10, piston push rod 12 and push rod top board 13, patrix 3 is installed in patrix lock sleeve 2, in the die cavity of patrix 3, is coated with expansion utricule 5.Expansion counterdie is installed on counterdie coupling assembling, expansion counterdie comprises expansion utricule counterdie 7, hydraulic cylinder 9 and hydraulic piston 11, on hydraulic cylinder 9, be provided with Hydraulic Relief Valve 8, hydraulic piston 11 is socketed in hydraulic cylinder 9, and expansion utricule counterdie 7 is communicated with hydraulic cylinder 9 sealings.Moving clamping plate 14 is connected with hydraulic cylinder 9 bottoms by screw, pull bar 10 connects moving clamping plate 14, on push rod top board 13, be provided with the slide opening matching with pull bar 10, slide opening slides on pull bar 10, and the two ends of piston push rod 12 are connected with screw with hydraulic piston 11 and push rod top board 13 respectively.
Patrix 3 is provided with syndeton with lower intermode, specifically between patrix 3 and piston cylinder 9, is provided with opening/closing/locking mechanism 4, and patrix 3 is connected with piston cylinder 9 separation or locking by opening/closing/locking mechanism 4.
The expansion utricule 5 covering in model cavity is the good silica gel sheath of elasticity with the expansion utricule counterdie 7 being connected with hydraulic cylinder 6.
Operation principle: expanding die machine needs to be arranged on the power to obtain on hydraulic press before operation, and wherein upper mould fixed plate 1 connects on hydraulic press, and pull bar 10 is the top pull bars on hydraulic press.Before processing, patrix 1 and counterdie components apart, the workpiece 5 of needs processing is enclosed within on expansion utricule counterdie 7, then patrix 1 closes, by opening/closing/locking mechanism 4, patrix 1 and hydraulic cylinder 9 are locked, and opening/closing/locking mechanism 4 is not only provided with one, but multiple, in demonstration figure, only draw an opening/closing/locking mechanism 4 in order to simplify.After upper and lower mould locking, hydraulic press comes into operation, hydraulic press pulls pull bar 10 to move downward, hydraulic expanding die machine entirety is moved downward, push rod top board does not move, and hydraulic piston 11 is moved upward relatively, and squeezed fluid hydraulic fluid flows to expansion utricule counterdie 7, the utricule counterdie 7 that makes to expand swells, the die cavity assembly of compressing workpiece 5 and patrix 1.After the successful moulding of workpiece 5, upper and lower mould separates, and takes out finished work-piece 5.
Excessive in order to prevent the hydraulic pressure in hydraulic cylinder 9, in the time that hydraulic pressure transfinites, hydraulic fluid overflows from Hydraulic Relief Valve 8, prevent in-cylinder pressure excessive and damage hydraulic cylinder.
