Abstract

The utility model relates to a side punch mould of groove work piece, belonging to the technical field of automobile mechanism, mainly comprising an adjusting mat, a sliding-wedge integrated with the up mould base, a lower mould base, a concave mould, punch head, sliding guide-plate, fixing plate and springs. The sliding-wedge is fixed on the workbench of pressing machine and the sliding guide-plate joins the fixing plate. A number of punch heads are set on the fixing plate. Two groups of sliding guide-plate and the fixing plate are fixed on the lower mould base. The adjusting mat joins the concave mould which is fixed on the lower mould base. During the running time, the workbench of pressing machine drives the sliding-wedge to go down to push the sliding guide-plate and the fixing plate of the two sides to press the punch head, and simultaneously the spring is pressed and then the punch head drill through the work piece and a punch is finished. The utility model is proper on structure and great on strength and has a long life, especially fitting the process of the groove work piece of thick plate material.

Description

A kind of side blow punch die of flute profile workpiece

Technical field

The utility model relates to a kind of side blow punch die of heavy frame cross, belongs to the automobile mechanical processing technique field.

Background technology

Make the field at heavy-duty car, the sheet material of crossbeam is thicker, be generally more than the 6mm, be the channel-section stamping parts, when the aerofoil of crossbeam is curved surface, the hole of aerofoil generally adopts the side blow mould to carry out punching, prevent bore deformation, but the side blow mould wedge because of stressed bigger, the loosening easily or fracture of set bolt, the mission life-span is low, and this has just increased production cost.

Summary of the invention:

The utility model is at the deficiencies in the prior art, provide a kind of rational in infrastructure, intensity is high, the side blow punch die of the flute profile workpiece of the suitable machining thick plates material of long service life.

The utility model purpose is finished by following technical measures.A kind of side blow punch die of flute profile workpiece is by adjusting cushion block, forming with wedge, sliding guide, fixed head, drift, spring, die and the die shoe of upper bolster one, wherein, be fixed on the forcing press movable table with the wedge of upper bolster one, sliding guide is connected with fixed head, fixed head is equipped with some drifts, two groups of sliding guides and fixed head are placed on the die shoe, adjust cushion block and are connected on the die, and die is fixed on the die shoe.

In the utility model when work, be positioned over die shoe on the press bench, is fixed on the forcing press movable table with the wedge of upper bolster one, and flute profile workpiece location is placed on the die; Starting pressure machine then, the forcing press movable table drives with the wedge of upper bolster one descending, promotes the sliding guide and the fixed head extruding drift of both sides, compress spring simultaneously, drift continues to cooperate the die in the grooved workpiece to the workpiece internal motion, finishes the punching action.The forcing press movable table is up then, with the wedge of upper bolster one under back-moving spring thrust, drift, fixed head are returned to original position, take off workpiece.Rational in infrastructure, advantages such as intensity is high, long service life that use the utlity model has are particularly suitable for the flute profile workpiece of machining thick plates material.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the grooved workpiece figure that processes among Fig. 1.

Wherein, 1, the grooved workpiece, 2, adjust cushion block, 3, with the wedge of upper bolster one, 4, die shoe, 5, die, 6, drift, 7, sliding guide, 8, fixed head, 9 springs.

The specific embodiment

Embodiment: structure as depicted in figs. 1 and 2, by adjusting cushion block 2, forming with wedge 3, sliding guide 7, fixed head 8, drift 6, spring 9, die 5 and the die shoe 4 of upper bolster one, wherein, be fixed on the forcing press movable table with the wedge of upper bolster one, sliding guide is connected with fixed head, and fixed head is equipped with some drifts, and two groups of sliding guides and fixed head are placed on the die shoe, adjust cushion block and be connected on the die, die is fixed on the die shoe.During work, the forcing press movable table drives with the wedge of upper bolster one descending, promotes the sliding guide and the fixed head extruding drift of both sides, compresses spring simultaneously, and drift passes workpiece, finishes the punching action.The forcing press movable table is up then, and drive breaks away from sliding guide with the wedge of upper bolster one, and under back-moving spring thrust, drift, fixed head and sliding guide are returned to original position, take off workpiece, finish a working cycles.

Claims

1, a kind of side blow punch die of flute profile workpiece, it is characterized in that, mainly by adjusting cushion block, forming with wedge, die shoe, die, drift, sliding guide, fixed head and the spring of upper bolster one, wherein, be fixed on the forcing press movable table with the wedge of upper bolster one, sliding guide is connected with fixed head, fixed head is equipped with some drifts, two groups of sliding guides and fixed head are placed on the die shoe, adjust cushion block and are connected on the die, and die is fixed on the die shoe.
