Abstract

The utility model disclose a hot-cutting, blanking and pressing mechanism, which comprises a die holder, positioning stop iron and a cutter, and further comprises a V-type sizing block positioned on the die holder, wherein a cylinder which is controlled by a travel switch is mounted right above the V-type sizing block; and upper V-type iron corresponding to the V-shaped sizing block is connected below the cylinder. The utility model adopts the cylinder to drive the V-type iron to press bar stocks in a gapless manner to solve the problems that the slopes of the cross sections of cut stock sections caused by displacement of the bar stocks in hot-cutting are large, and the weight of the stock sections is instable, thereby improving the quality and the yield of the product, saving the raw materials, and reducing the production cost.

Description

A kind of fervent blanking hold-down mechanism

Technical field

The utility model relates to a kind of fervent blanking hold-down mechanism, and particularly a kind of cylinder drive v block that utilizes does not have the fervent blanking hold-down mechanism that the gap compresses.

Background technology

Be mechanical to compressing of bar in traditional fervent blanking operation, in the process that mechanical type compresses, bar need be fixed motionless, for bar is sent into the cutter tube smoothly, between hold down gag and the bar certain clearance must be arranged, yet, charge bar was subjected to displacement when the existence in gap can cause blank, thereby further caused the weight poor stability of institute's blank section, and material section end face gradient is big, influence the quality and the yield of product, waste raw material and cost.Therefore, existing fervent blanking hold-down mechanism is demanded urgently improving.

The utility model content

The purpose of this utility model provides a kind of fervent blanking hold-down mechanism, utilizes cylinder drive v block that workpiece is not had the gap and compresses, and has realized the accurate cutting to workpiece, has improved product quality and acceptance rate.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of fervent blanking hold-down mechanism comprises die holder, and location buting iron and cutting knife also comprise the V-type parallels that is positioned on the die holder; Cylinder by travel switch control is installed directly over the described V-type parallels; Described cylinder push-rod is connected with and the corresponding v block of going up of V-type parallels.

The beneficial effects of the utility model are, adopting cylinder drive v block that bar is not had the gap compresses, the displacement of bar when effectively having avoided fervent, make that the material section end face gradient of fervent gained is little and weight stable, product quality and yield have been improved, reduce raw-material consumption, reduced production cost.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is the front view of the described fervent blanking hold-down mechanism of the utility model embodiment;

Fig. 2 is the right view of the described fervent blanking hold-down mechanism of the utility model embodiment.

Among the figure:

1, cutting knife; 2, die holder; 3, V-type parallels; 4, bar; 5, go up v block; 6, cylinder; 7, location buting iron.

The specific embodiment

As shown in Figure 1, the described fervent blanking hold-down mechanism of the utility model embodiment comprises die holder 2, and location buting iron 7 and cutting knife 1 further comprise the V-type parallels 3 that is positioned on the die holder 2; Cylinder 6 by travel switch control is installed directly over the described V-type parallels 3; Described cylinder 6 belows are connected with and the V-type parallels 3 corresponding v blocks 5 of going up.

Earlier bar 4 is placed on the V-type parallels 3, when the lathe slide block slides to top dead-centre, the upper stroke switch action, drive cylinder 6 promotes to go up v block 5 and compresses bar 4; Blank finishes when the lathe slide block slides to bottom dead centre, the lower stroke switch action, and control cylinder 6 drives goes up v block 5 withdrawals, and bar 4 is fed to buting iron 7 places, location and waits for fervent next time.

Claims

1. a fervent blanking hold-down mechanism comprises die holder, and location buting iron and cutting knife is characterized in that, also comprise the V-type parallels that is positioned on the die holder; Cylinder by travel switch control is installed directly over the described V-type parallels; Described cylinder push-rod is connected with and the corresponding v block of going up of V-type parallels.
