Abstract

The utility model belongs to an impact press which comprises a machine foundation, a transverse beam, a punch sliding block, a male mould and a workbench. The utility model is characterized in that the transverse beam is provided with an impact air cylinder on which an air inlet and an air outlet are arranged. The air inlet and the air outlet are respectively connected with an air storing tank by a corresponding electrical controlled valve and an air delivering pipe. The male mould is connected with a piston rod which is arranged in the impact air cylinder by the punch sliding block, and a female mold is arranged on the workbench. The impact force and impact stroke of the male mold can be regulated and controlled by the utility model in a stepless mode. Compared with a friction press with the same tonnage, power consumption can be saved by 80%, manufacturing cost can be saved by 1/3, maintenance is convenient and service life is long.

Description

The Pneumatic impact forcing press

The utility model belongs to the forcing press field, relates generally to impact press.

The forcing press of using in enterprise produces utilizes screw thread or toggle power transmission mostly at present, although this type of forcing press can be applied to have following problem in the production technologies such as cold forging, punching press and stretching in actual production preferably:

(1) energy consumption is bigger, produces less economical.

(2), therefore make equipment seem heaviness and inconvenient operation because the subsidiary usually action bars of equipment.

(3) lack the maintenance cost height service life.

(4) impulsive force of forcing press formpiston and impact stroke can not be stepless regulated.

The purpose of this utility model is to overcome above-mentioned technical deficiency, and stepless regulated impulsive force of a kind of energy and impact stroke, easy and simple to handle and Pneumatic impact forcing press that energy consumption is low are provided.The utility model adopts following technical scheme: the crossbeam that comprises support, workbench, column, links with the column upper end, and and the drift slide block that links of column, formpiston is arranged on the drift slide block, workbench and column link, it is characterized in that installing on the crossbeam blow cylinder, air inlet and exhaust outlet are set on the blow cylinder, formpiston links by drift slide block and the piston rod that is arranged in the blow cylinder, and former is set on the workbench.

Exhaust outlet on the blow cylinder of the present utility model connects fast-discharge valve and exhaust speed-regulating control device.Workbench is connected on the column by the sliding sleeve that cooperates with column.The damping spring of equidistant arrangement is set between workbench and the support.

The utility model can stepless regulated forcing press formpiston impulsive force and impact stroke, the scope of application is wide; And simple in structure, easy to operate, and compare with tonnage screw press, can save power consumption 80%, save manufacturing cost 1/3; Because the frictional dissipation of no ox-hide circle, no screw rod, so fault rate is low, is convenient to maintenance, long service life.

Below in conjunction with accompanying drawing the utility model is further elaborated.

Accompanying drawing 1 is the structural representation of the utility model embodiment;

Fig. 2 is the draw bail schematic diagram of blow cylinder and air accumulator among Fig. 1.

As shown in the figure: support 10 is fixed on the pre-embedded bolt of ground, and the hydraulic pressure knockout is housed in the support 10.The support both sides fixedly mount two root posts 5, and crossbeam 2 is installed in column 5 upper ends, and blow cylinder 1 is installed in crossbeam 2 middle parts.The drift slide block 3 of splicing on the piston rod 16 of blow cylinder 1 is equipped with formpiston 4 on the drift slide block, column 5 lower end installment work platforms 7 are installed former sliding sleeve and former 6 on the workbench 7.

Open switch 22, the gas in the air accumulator 21 enters blow cylinder chamber 17 through flow through stop valve 20, exhaust outlet 18 of appendix 14.Piston 15 moves under the effect of air pressure, rises to predetermined altitude by piston rod 16 drive drift slide blocks 3, formpiston 4.This moment, blow cylinder 1 entered readiness for operation.The beginning of working then, stop valve 13 charged opening, gas enters air reservoir chamber 12 through air inlet 11.When the gas in the air reservoir chamber 12 increased to certain pressure, stop valve 20 charged closing were by fast-discharge valve 19 rapid exhausts.Gas pressure in the cylinder chamber 17 is lower than the gas pressure in the air reservoir chamber 12.Like this, under the acting in conjunction of high speed and high pressure air-flow and gravity, drift slide block 3 falls rapidly with formpiston 4, and under the powerful kinetic energy effect of formpiston 4, the powder of moulding to be processed makes product molding in the formpiston 4 percussive pressure die sinking 6.Be the good moulding of assurance goods, stop valve 20 Time Delay Openings, the powders in 4 pairs of formers of formpiston 6 are implemented the impact types pressurization and can be kept the high pressure of several seconds to hold time like this, thus the new technology approach of realization surge operations for forming.For adapting to formpiston 4 times towards the speed of service, 19 places are provided with the exhaust speed-regulating control device at fast-discharge valve.Then, stop valve 20 is opened, and stop valve 13 is closed, and cylinder chamber 17 air inlets under the effect of air pressure, move on the piston 15, rises to predetermined altitude by piston rod 16 drive drift slide blocks 3, formpiston 4, and formpiston 4 proposes in former 6.Held out by the former inner bottom plating of hydraulic pressure knockout institute jacking behind the product molding, finish the time processing process.Afterwards, stop valve 13 charged opening, stop valve 20 is closed, and another working cycles begins.

Be the impulsive force of 4 pairs of formers 6 of buffering formpiston, alleviate the equipment vibrations, between workbench 7 and column 5, sliding sleeve 8 is set, between workbench 7 and the support 10 damping spring 9 is set.Workbench 7, sliding sleeve 8 and damping spring 9 are formed shock mitigation system together.When formpiston 4 came downwards to workbench 7, workbench 7 moved down as trace, the impulsive force of 4 pairs of formers 6 of available buffer formpiston like this, thus prolong service life of mould.
