Abstract
A bearing bush forming tool for a punch press relates to technical equipment for machining and particularly relates to a bearing bush forming tool for a punch press. The bearing bush forming tool comprises a circular bending die, a lower die plate, shaping blocks, a middle block, a pre-bent block, a square rod, a top cover, a spring seat, a spring and a die holder, the circular bending die is fixed onto the lower die plate, an arc-shaped groove is arranged on the circular bending die, the top cover is connected to the lower end of the die holder, the spring is disposed in a central hole of the die holder, the spring seat is arranged under the spring, the lower peripheral edge of the spring is abutted onto the top cover, the middle block is disposed below the top cover and fixedly connected with the top cover by an inner hexagon screw, the square rod is arranged in central through holes of the top cover and the middle block, the upper end of the square rod is connected with the spring seat, the pre-bent block is connected to the lower end of the square rod, the lower end surface of the pre-bent block is a spherical surface, and the shaping blocks are fixedly connected to the front and the rear of the middle block. The bearing bush forming tool solves problems that existing bearing bush forming technical equipment is low in machining efficiency, high in machining error, complicated in operation and high in labor intensity of workers.
Description
Technical field
The utility model relates to machining and uses technological equipment, the bearing shell shaping jig that is specifically related to use on the punch press.
Background technology
At present bearing shell moulding process equipment have that working (machining) efficiency is low, mismachining tolerance big, complicated operation, shortcoming that labor strength is big.
The utility model content
The purpose of the utility model provides a kind of bearing shell shaping jig that is used for punch press, and the utility model has solved that existing bearing shell moulding process equipment exists that working (machining) efficiency is low, mismachining tolerance big, complicated operation, problem that labor strength is big.
The bearing shell shaping jig that is used for punch press of the utility model is made up of circular bending die 1, lower bolster 2, dressing stick 5, intermediate mass 6, pre-bending piece 7, square bar 10, top cover 11, spring base 12, spring 13, die holder 14; Circular bending die 1 is fixed on the lower bolster 2; The groove that circular arc is arranged above the circular bending die 1; Die holder 14 lower ends are connected with top cover 11; Be provided with spring 13 in the centre bore of die holder 14, spring base 12 arranged below the spring 13, spring base 12 following peripherals withstand on the top cover 11; Intermediate mass 6 is arranged below top cover 11, and intermediate mass 6 is fixedly connected with top cover 11 through soket head cap screw 9; In top cover 11 and intermediate mass 6 central through holes, be provided with square bar 10, square bar 10 upper ends connect spring base 12, and square bar 10 lower ends connect pre-bending piece 7, and pre-bending piece 7 lower surfaces are spherical; Be fixedly connected with dressing stick 5 in intermediate mass 6 front and back sides.
Under the blank material of bearing shell, need bend into a semicircle after good, the utility model provide a kind of on punch press, use can be with the diel of bearing shell rapid processing moulding.This mould is installed on the punching press base of punch press bearing bush billet to be processed is placed in the mould, starts punch ram then and once accomplishes processing work.
The bearing shell shaping jig that is used for punch press of the utility model, have improve working (machining) efficiency, mismachining tolerance is little, simple to operate, the advantage that labor strength is low.
