Abstract
The utility model discloses a die with a hydraulic discharging device, which aims at providing the die with the hydraulic discharging device with high location precision and big pressing force. The die comprises an upper die and a lower die and is characterized in that a swaging pin is connected on a discharging plate and penetrates through the upper die; an upper bed is connected with an oil cylinder, a piston, a hydraulic pipeline and a control device; and the swaging pin is connected with the top end of the piston. In the utility model, the die adopts the hydraulic pressure to compress work pieces by the power transmission of the swaging pin when in discharging, which has the characteristics of big compression pressure and precise location and is applicable for punching press with high precision.
Description
Technical field
The utility model relates to cold-punching mold, relates in particular to the mould of band hydraulic stripper device.
Background technology
In cold stamping processing, all be with device for discharging for the general mould of fixation workpiece, workpiece is pressed in before punching press on the mould, implement punch process again.Common device for discharging has spring or block rubber, utilizes strain with the stripper fixation workpiece, and such device for discharging is poor location often, and thrust is little, and difficulty satisfies high-precision punch process.
The utility model content
The purpose of this utility model provides a kind of positioning accuracy height, the mould of the band hydraulic stripper device that thrust is big.
In order to reach above-mentioned requirements, the utility model is achieved through the following technical solutions: it includes upper die and lower die, it is characterized in that on stripper, being connected with the binder pin, the binder pin passes patrix, be connected with on the platform of going to bed and comprise oil cylinder, piston and fluid pressure line and control device, the binder pin is connected with the top of piston.
The mould of the band hydraulic stripper device of making according to such scheme by the power transmission of binder pin, use the hydraulic coupling workpiece pressing when discharging, it is big to have thrust, and the characteristics that the location is accurate are fit to the use of high accuracy punch process.
Description of drawings
Fig. 1 is the mould structure schematic diagram of band hydraulic stripper device.
Wherein: 1, patrix; 2, counterdie; 3, stripper; 4, binder pin; 5, the platform of going to bed; 6, hydraulic jack; 7, piston; 8, fluid pressure line and control device.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of the mould of band hydraulic stripper device.As seen from the figure, it includes patrix 1 and counterdie 2, is connected with two binder pins 4 on stripper 3, and binder pin 4 passes patrix 1, be connected with on the platform 5 of going to bed and comprise hydraulic jack 6, piston 7 and fluid pressure line and control device 8, binder pin 4 is connected with the top of piston 7.Described hydraulic jack 6 is a two-way cylinder.
Claims (2)
1, the mould of band hydraulic stripper device, it includes upper die and lower die, it is characterized in that being connected with on stripper the binder pin, and the binder pin passes patrix, be connected with on the platform of going to bed and comprise oil cylinder, piston and fluid pressure line and control device, the binder pin is connected with the top of piston.
