Abstract

The utility model relates to a die capable of changing resistance force of draw bead, which comprises a punch, a cavity die, a pressure plate, a draw bead, a draw bead bearing plate, a push-rod, a nitrogen cylinder and the like, wherein the draw bead is separated from the cavity die or the pressure plate, an air cushion and an ejector rod of a machine tool can push the draw bead bearing plate to move, and the height of the draw bead is controlled by the air cushion through the ejector rod. The resistance force of the draw bead varies with the changes of punching stroke during the whole drawing process. The resistance force of the draw bead in the die is convenient to control, which is extremely effective for improving the product quality in the actual production.

Description

A kind of mould with alterable brake bead resistance
Technical field
The utility model belongs to Stamping Die Technology, is specifically related to a kind of alterable brake bead resistance mould, mainly is the mould at the alterable brake bead height.
Background technology
Present diel, the convex tendon of bead are fixed on holding pad or the die usually, and the bead resistance is changeless in whole draw forming process.Along with punching stroke, requiring the bead resistance is the draw forming that changes for needs, and this fixed form just can't realize.Simultaneously, this bead is fixed on the mode on holding pad or the die, also is not easy to repair a die, sometimes may cause and scrap holding pad or die because bead can't repair, this has just increased repairing a die the time of mould, reduces the service life of mould, thereby increases production cost.
Summary of the invention:
The utility model can't change the problem of alterable brake bead resistance at existing mold, and a kind of mould with alterable brake bead height is provided, thereby realizes alterable brake bead resistance.
The technical solution of the utility model is as follows:
For double action press, the mould that originally has alterable brake bead resistance comprises punch, die, holding pad, push rod, and punch is installed on the inner slide, and holding pad is installed on the outer slide, and die is installed on the lower table; It also is provided with independently bead and bead backing plate, and described bead passes from die, and the lower end is by end in contact on bead backing plate and the push rod.
For single action press, the mould with alterable brake bead resistance comprises punch, die, holding pad, push rod and nitrogen cylinder, and die is installed on the top shoe, and punch is installed on the die shoe, and the nitrogen cylinder is installed on the die shoe, and holding pad is withstood in the working end of nitrogen cylinder; It also is provided with independently bead and bead backing plate, and holding pad is passed in described bead upper end, and the lower end is by end in contact on bead backing plate and the push rod.
The topmost improvement of the utility model is that bead is separated from die or holding pad; push rod promotes the motion of bead backing plate; its resistance can change along with the variation of punching stroke, thereby but make bead height free adjustment by air cushion by the push rod free adjustment.
The utility model is big to the adjusting quantitative change of bead resistance, and convenient, and actual production is very effective to improving the quality of products.Simultaneously, this mold repair is convenient, can reduce mould and repair a die the time, prolongs the service life of mould, reduces production costs.
Description of drawings
Fig. 1 is the mould of alterable brake bead resistance---two moving.
Fig. 2 is the mould of alterable brake bead resistance a---single action.
Among the figure: 1-punch, 2-holding pad, 3-bead, 4-die, 5-bead backing plate, 6-push rod, 7-nitrogen cylinder, 8-die shoe.
The specific embodiment
Referring to Fig. 1, the mould of alterable brake bead resistance (two moving) comprises punch 1, die 4, holding pad 2, bead 3, bead backing plate 5 and push rod 6.Punch 1 is installed on the inner slide, and holding pad 2 is installed on the outer slide, and die 4 is installed on the workbench.Independently bead 3 upwards passes from die 4, and the lower end is by end in contact on bead backing plate 5 and the push rod 6.Push rod 6 promotes bead backing plate 5 and moves up and down, thereby regulates bead 3 height.Push rod 6 is connected with air cushion, utilizes lathe self function, regulates the power that push rod 6 is provided, and the resistance of bead is changed along with the variation of punching stroke.
Referring to Fig. 2, the mould of alterable brake bead resistance (single action) comprises die 4, punch 1, bead 3, holding pad 2, nitrogen cylinder 7, bead backing plate 5, die shoe 8 and push rod 6.Die 4 is installed on the slide block, and punch 1 is installed on the die shoe 8.Nitrogen cylinder 7 also is installed on the die shoe 8, and holding pad 2 is withstood in the working end of nitrogen cylinder 7.Independently holding pad 2 is passed in bead 3 upper ends, and the lower end is by end in contact on bead backing plate 5 and the push rod 6.Push rod 6 promotes bead backing plate 5 and moves up and down, and regulates the height of bead 3.Pressure-plate-force utilizes nitrogen cylinder 7 to realize.Push rod 6 is connected with air cushion, utilizes lathe self function, regulate the power that push rod 6 is provided, thereby the resistance of bead is changed along with the variation of punching stroke.
