Abstract

The invention belongs to the technical field of molding of fan-shaped plates and relates to a one-time molding process of multiple fan-shaped plates, which is completed according to the following steps: (1) producing rectangular stamping billets according to the corresponding dimensions of the fan-shaped plates; (2) aligning more than two produced stamping billets according to the corresponding sides and mutually overlapping; (3) placing the plate surface of single stamping billet of the stamping billets after overlapping on a lower fan-shaped matrix of a stamping die in the vertical direction, and using a stop block and a movable clamping plate for positioning and clamping the stamping billets after overlapping in both the transverse direction and the longitudinal direction; (4) starting a stamping machine tool, using a sliding block of the stamping machine tool to drive an upper fan-shaped punch and the lower fan-shaped matrix with concentric circles to combine the die, and stamping the stamping billets into the fan-shaped plates; and (5) or keeping the pressure for 1-5 seconds after combining the die, starting the die, and taking out the stamped fan-shaped plates. The one-time molding process has the advantages of saving raw materials, realizing low production cost, leading the produced products to be in line with the IT14 grade precision standard. The one-time molding process is applicable to processing the flat plates to the fan-shaped plates.

Description

The once through moulding technology of the fan-shaped plate of multi-disc

Technical field

The invention belongs to the field shaping technique of fan-shaped plate, refer in particular to the once through moulding technology of the fan-shaped plate of a kind of multi-disc.

Background technology

As shown in Figure 1: fan-shaped plate does not have crimp, is a typical flat part, and existing processing method generally adopts the method for stamping and blanking to produce; Figure 2 shows that the stock layout figure of stamping and blanking, behind fan-shaped plate stamping and blanking, scrap (bridge) outside the fan-shaped plate will all be wasted as leftover bits and pieces, stock utilization only reaches 78%, according to the method, and 5 fan-shaped plates of every stamping-out, will produce the waste material that is equivalent to a fan-shaped plate workpiece, obviously adopt the stamping and blanking method, waste of material is big, the production cost height.

Summary of the invention

The purpose of this invention is to provide a kind ofly save material, production cost is low, the product produced meets the fan-shaped plate of multi-disc of IT14 class precision standard once through moulding technology.

The object of the present invention is achieved like this:

The once through moulding technology of the fan-shaped plate of multi-disc, finish as follows:

(1) makes the punching press stock by the thick size of length and width of fan-shaped plate correspondence;

(2) the punching press stock more than two that step (1) is produced is by corresponding sides alignment and mutual superposition;

(3) the punching press stock after will superposeing is sidelong from one of diel on the following fan-shaped die of diel by the upright direction of the plate face of monolithic punching press stock, and the punching press stock after will superposeing with block and ambulatory splint laterally reaches longitudinal register and clamps;

(4) start press machine, the slide block of press machine drive have concentrically ringed fan-shaped punch descending and with fan-shaped die matched moulds down, the punching press stock is struck out fan-shaped plate;

(5) opening mold or behind matched moulds 1~5 second opening mold of pressurize, take out rammed fan-shaped plate.

Above-mentioned when stamping machine work matched moulds compresses, when upward fan-shaped punch was pressed into the punching press stock, the punching press stock took place upright to bending, and the punching press stock is upright should be less than the percentage elongation of material to the lower limb elongation of bending.

The punching press stock of above-mentioned mutual superposition has more than 40 or 40; The punching press stock of mutual superposition of the present invention is preferably 40.

Above-mentioned punching press stock is made with aluminium alloy plate or steel plate materials; Punching press stock of the present invention is preferably aluminium alloy plate.

The outstanding compared to existing technology advantage of the present invention is:

The present invention utilizes the characteristic of workpiece, with the punching press stock mutual superposition more than two, makes the punching press stock take place to stand by stamping die again and obtains fan-shaped plate to bending, and the product of save material, production cost is low, producing meets IT14 class precision standard.

The specific embodiment

The present invention is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 3-5:

Embodiment one:

The once through moulding technology of the fan-shaped plate of multi-disc, finish as follows:

(1) being that 412mm is wide by the length of fan-shaped plate correspondence is 1.2mm size making tablet 10 for 25mm is thick.

(2) 40 punching press stocks 10 that step (1) is produced are by corresponding sides alignment and mutual superposition;

(3) the punching press stock 10 after will superposeing is sidelong from one of diel on the following fan-shaped die 30 of diel by the upright direction of the plate face of monolithic punching press stock 10, and the punching press stock 10 after will superposeing with block 32 and ambulatory splint 33 laterally reaches longitudinal register and clamps;

(4) start stamping machine, having concentrically ringed fan-shaped punch 31 and descending fan-shaped die 30 matched moulds of stamping machine strikes out fan-shaped plate with punching press stock 10;

Above-mentioned when stamping machine work matched moulds compresses, when upward fan-shaped punch 31 was pressed into punching press stock 10, punching press stock 10 took place upright to bending, the percentage elongation that founds the material of lower limb elongation≤punching press stock 10 when bending of punching press stock 10.

The punching press stock 10 of above-mentioned mutual superposition has 40 or 60; The punching press stock 10 of mutual superposition of the present invention is preferably 40.

Above-mentioned punching press stock 10 usefulness aluminium alloy plates or steel plate materials are made; Punching press stock 10 of the present invention is preferably aluminium alloy plate.

Embodiment two:
