Description

Turn over reaming integral type mould structure

Technical Field

The utility model relates to a car chassis mould processing field, specific saying is a turn over reaming integral type mould structure.

Background

At present, the chassis structural parts of more household cars adopt an assembly form of firstly hole flanging and then bushing pressing. For product design requiring both hole flanging and hole expansion, the original mold manufacturing process is completed by dividing hole flanging and hole expansion into two steps, with reference to fig. 1. The process difficulty is reduced by two steps in the traditional process, but with the development of science and technology, the stamping process of the traditional process has multiple stamping procedures and high die manufacturing and stamping production cost.

In order to reduce the stamping cost and simplify the process flow, it is necessary to design a hole-flanging integrated die structure.

Disclosure of Invention

The utility model discloses a prior art's a difficult problem has been broken through, a reaming integral type mould structure has been designed.

In order to achieve the purpose, the utility model discloses a turn over reaming integral type mould structure, including the upper die base, elastic element, the hole flanging terrace die, the work piece, go up mould slide wedge drive block, the activity die, the reaming terrace die, press the flitch, the die holder, go up the mould drive block, the slide wedge slider, the work piece sets up on the die holder, press the flitch to compress tightly the work piece, the hole flanging terrace die is established in the top of work piece processing hole, the below at work piece processing hole is established to the reaming terrace die, the lower extreme and the slide wedge slider of reaming terrace die are connected, the activity die sets up on the die holder, be located the both sides of reaming terrace die, the upper end and the upper die base of going up the mould slide wedge drive block are connected, the lower extreme passes the through-hole of die holder, the upper end and the upper die base of going up the mould drive block are connected, the lower extreme contacts with the slide wedge slider.

The upper die wedge driving block is connected with the upper die base in a sliding mode.

The upper die base is connected with the material pressing plate through bolts.

The upper die wedge driving block is contacted with or separated from the sliding block of the movable female die.

Compared with the prior art, the hole flanging and hole expanding two processes can be simultaneously completed through the integrated structure of the hole flanging male die and the hole expanding male die, so that the process flow is simplified; the flanging hole adopts a die, so that the manufacturing cost and the stamping cost of the die are saved; meanwhile, the die is simple to operate, and labor cost is saved.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

With reference to fig. 2-3, the utility model discloses a hole flanging integrated die structure, including upper die base 1, elastic element 2, hole flanging terrace die 3, work piece 4, upper die slide wedge drive block 5, movable die 6, reaming terrace die 7, pressure flitch 8, lower die base 9, upper die drive block 10, slide wedge slider 11, work piece 4 sets up on lower die base 9, pressure flitch 8 compresses tightly work piece 4, upper die base 1 and pressure flitch 8 adopt bolted connection; the hole flanging male die 3 is arranged above a machined hole of a workpiece 4, the hole expanding male die 7 is arranged below the machined hole of the workpiece 4, the lower end of the hole expanding male die 7 is connected with a wedge slide block 11, the movable female die 6 is arranged on a lower die base 9 and located on two sides of the hole expanding male die 7, the upper end of an upper die wedge driving block 5 is in sliding connection with an upper die base 1, the lower end of the upper die wedge driving block passes through a through hole of the lower die base 9, the upper die wedge driving block 5 is in contact with or separated from a slide block of the movable female die 6, the upper end of an upper die driving block 10 is connected with the upper die base 1, and the lower end of the upper die driving block is in contact with the wedge slide block 11.

In the stamping process, a workpiece 4 is placed on the upper die holder 1, and a machine tool is started. The upper die wedge driving block 5 contacts with a sliding block of the movable female die 6 to drive the movable female die 6 to close towards the center, meanwhile, the upper die base 1 drives the pressure plate 8 to move downwards to press the workpiece 4 and drive the movable female die 6, and after the pressure plate is pressed, the hole flanging male die 3 moves downwards to perform hole flanging; after hole flanging is completed, the upper die base 1 continues to move downwards, the reaming male die 7 starts to move upwards after the upper die driving block 10 is contacted with the wedge sliding block 11, the reaming male die 7 moves upwards to be contacted with the hole flanging male die 3, the hole flanging male die 3 moves backwards to start hole reaming, the upper die base 1 and the lower die base 9 are completely closed, and hole flanging and hole reaming are completed. When the machine tool moves upwards, the upper die base and the lower die base are opened, the movable female die 6 retracts, and then the workpiece 4 can be taken out.
