Abstract

The invention relates to the technical field of blowing devices, in particular to a blowing device for a multi-station pressure machine, which comprises a die shank, a cylindrical blowing convex die, two clamping blocks, a material withdrawing core, a cushion block with inner holes and an air supply device used for providing an air source. The lower end of the die shank is fixedly connected with the top of the blowing convex die, an air inlet hole is arranged in the middle of the blowing convex die, a plurality of air outlet holes which are circumferentially uniformly distributed are disposed on the outer wall of the lower portion of the blowing convex die, the air supply device is communicated with the air inlet hole by a pipeline, the two clamping blocks are oppositely disposed on two sides of the bottom end of the blowing convex die, the top of the cushion block contacts with bottom surfaces of the two clamping blocks, and the material withdrawing core is inserted in an inner hole of the cushion block. An airflow method is adopted, the air supply device is used for the blowing device of the multi-station pressure machine, accordingly, strong airflow is conveniently used for blowing impurities away from the surface of a workpiece, simultaneously, the workpiece can be clamped due to the design of the clamping blocks while a correction effect can be realized, and the workpiece can be stably conveyed to a next station.

Description

A kind of multiple position press blowing device

Technical field

The present invention relates to the blowing device technical field, particularly a kind of multiple position press blowing device.

Background technology

Multiple position press is to develop a kind of advanced person's metal forming machinery rapidly; Have that automaticity height, productivity ratio are high, personnel selection less, few, the handling safety of floor space, stamping parts with short production cycle and advantage that integrated cost is low, it does not need half-finished transportation and stacks area; The mould simplification is convenient to make, and long service life.Multiple position press is advanced press equipment, is the integrated of many forcing presses, generally is made up of the end of a thread unit, feed mechanism, forcing press and line portion.

When utilizing workpiece of transfer press machined, owing to often leave the residue of last process on the workpiece, the little iron filings that get off like blanking etc.; If these foreign material are not got rid of; Bring influence can for one manufacturing procedure in back, thereby make the quality of workpiece be affected, adopt the labor cleaning; Waste time and energy, production capacity is low.

Summary of the invention

The technical problem that the present invention will solve is: a kind of multiple position press blowing device is provided, and solving existing equipment has foreign material entering workpiece inwalls such as iron filings easily in work such as blanking, stretching, thereby influences the technical problem of the quality of workpiece.

The technical solution adopted for the present invention to solve the technical problems is: a kind of multiple position press blowing device; Comprise die shank, columnedly blow material punch, two fixture blocks, material returned cores, have the cushion block of endoporus and the feeder of source of the gas is provided; Said die shank lower end is fixedly connected with blowing material punch top, blows material punch middle part and has air admission hole, blows the venthole that has a plurality of circumference uniform distributions on the outer wall of material punch bottom; Said feeder is communicated with air admission hole through pipeline; Two fixture blocks are oppositely arranged on and blow material both sides, punch bottom, and the top of said cushion block contacts with two fixture block bottom faces, and material returned core is inserted in the endoporus of cushion block.Feeder is as the major impetus source of blowing material; In blowing the material process, fixture block plays the effect that the location clamped and be passed to next station, and the cushion block of fixture block lower end design is simultaneously effectively protected workpiece; Work is remained on the working face, the work of convenient next station.

For all directions can both be blown, accomplish to make an overall screening the function of foreign material, as preferably, said venthole has eight.

The invention has the beneficial effects as follows; Multiple position press blowing device of the present invention; Through adopting the method for air-flow, introduce feeder, utilize powerful air-flow with the foreign material surface of the work that blows off easily; Can also play the effect of correcting when the design of fixture block can clamp workpiece simultaneously, make workpiece can be delivered to next station stably.

The specific embodiment

Combine accompanying drawing that the present invention is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.

Like the most preferred embodiment of of the present invention a kind of multiple position press blowing device of Fig. 1～shown in Figure 9, comprise die shank 1, columnedly blow material punch 2, two fixture blocks 3, material returned cores 4, have the cushion block 5 of endoporus and the feeder 6 of source of the gas is provided, die shank 1 lower end expects that punch 2 tops are fixedly connected with blowing; Blow material punch 2 middle parts and have air admission hole 21; Blow the design that has 22, eight ventholes 22 of venthole of eight circumference uniform distributions on the material punch 2 bottom outer walls, effectively guaranteed the air blowing of all directions; Accomplish comprehensive cleaning; Guarantee the surface of the work no-sundries, feeder 6 is communicated with air admission hole 21 through pipeline, and two fixture blocks 3 are oppositely arranged on and blow material both sides, punch 2 bottom; The top of cushion block 5 contacts with two fixture block 3 bottom faces, and material returned core 4 is inserted in the endoporus of cushion block 5.Wherein two fixture blocks 3 can play the effect that the location clamped and be passed to next station; And cushion block 5 can guarantee that workpiece remains on working face; Make whole device stability improve greatly, the material returned core 4 that is inserted into simultaneously in cushion block 5 endoporus can make workpiece turn back on the working face.

When using this device cleaning workpiece, owing to die shank 1 is fixed on the lathe slide block, when the lathe slide block moves; Air blowing punch 2 is also made same moved further, and when air blowing punch 2 during soon near workpiece, feeder 6 begins to blow automatically; When air blowing punch 2 left workpiece, feeder 6 stopped to blow, and fixture block 3 is clamped workpiece then; Steadily be sent to next station, so far accomplish and once blow the material action.

With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
