Description

Prevent the mould structure of jump-scrap

Technical field

The utility model is relevant with a kind of diel, refers to a kind of mould structure that prevents jump-scrap especially.

Background technology

In punching course, can in the punching of counterdie, aspirating hole be set usually in the past; When patrix or drift carry out punching press to workpiece; the waste material that is swept away is by after the drift punching press is to the punching; can be by aspirating hole with negative pressure with the waste material sucking-off; thereby avoid being brought to the counterdie die face by drift; next workpiece is when carrying out punching press, and waste material may produce mark problem such as cosmetic damage that workpiece caused or surface weigh wounded.

Yet, when the punching of small size (dash as the salad essence, diameter 3.3mm is following), utilize negative pressure mode such as bleed, also often too small because of the waste material volume, and can't be in the moment of drift punching press to the punching, effectively with waste material sucking-off immediately.When especially drift is punched down, the punching upper end is sealed by patrix, make its inside be enclosure space, so the suction that can produce is also comparatively limited, so that waste material still might and be brought to outside the punching along with the drift rise, and drop on workpiece or counterdie die face, thereby lose the effect that prevents jump-scrap, also can't guarantee the quality such as attractive in appearance of product surface.

Simultaneously, above-mentioned utilization negative pressure mode such as bleed also must be bled by external pump, so must provide electric power to pump again, causes the electric power burden of equipment.

The utility model content

In view of this, the purpose of this utility model is to provide a kind of mould structure that prevents jump-scrap,

In order to reach above-mentioned purpose, the utility model provides a kind of mould structure that prevents jump-scrap, and the described mould structure of jump-scrap that prevents comprises:

Template which is provided with the punching that penetrates its die face, and described punching end then is connected with a material-dropping hole that communicates, and the aperture of material-dropping hole is greater than its pairing described punching; And

Magnetic element, its inside is hollow, and described magnetic element is located on the material-dropping hole inwall, and relative with punching and communicate.

As preferred version, wherein said template is a counterdie.

As preferred version, wherein said magnetic element is magnet or electromagnet.

The utlity model has following beneficial effect:

The utility model is provided with magnetic element at the punching end of counterdie, is adsorbed in order to the waste material with institute's punching press, waste material is brought to outside the punching when avoiding drift to go up again and drops on workpiece or counterdie die face, consequently influences the aesthetic property of finished surface etc.

Therefore the utility model need not to continue external electric power in the process of punching press because it adsorbs waste material by magnetic element, can effectively reduce the power consumption of equipment, to save the energy.

The utility model is located at the magnetic element in the template, and when a drift during towards the punching punching press, drift can bring to waste material magnetic element inside, so that waste material is adsorbed by magnetic element, thereby reaches the purpose that prevents jump-scrap.

The specific embodiment

In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet its only provide with reference to and usefulness is described, be not to be used to limit the utility model.

See also Fig. 1 and Fig. 2, be respectively the sectional perspective schematic diagram of in-built generalized section of the utility model and main structure.The utility model provides a kind of mould structure that prevents jump-scrap, comprises a template 1 and at least one magnetic element 2; Wherein:

Template 1 can be a counterdie, and is provided with at least one punching 10 penetrating template 1 die face, the quantity of punching 10 cooperate with the position desire the workpiece 5 (promptly as shown in Figure 3) of punching out and be provided with.Punching 10 upper ends form opening by the extension of template 1 die face, punching 10 ends then connect a material-dropping hole that communicates 11, the aperture of material-dropping hole 11 is greater than its pairing punching 10, and material-dropping hole 11 extends to template 1 below and forms opening, can be bumped in material-dropping hole 11 by template 1 below for magnetic element 2 and be located on its inwall.

Magnetic element 2 can be magnet or electromagnet, is hollow in it and relative with this punching 10 and communicate, and with in punching course, can be brought to magnetic element 2 inside for waste material after by punching 10, immediately waste material is adsorbed onto on its inwall by magnetic element 2.

By above-mentioned contexture, can obtain the mould structure that the utility model prevents jump-scrap.

In view of the above, as shown in Figure 3, when desiring to carry out the punching press processing procedure, a patrix 4 is positioned at template 1 top, and patrix 4 is provided with downwards the drift 40 with respect to punching 10, the quantity of drift 40 according to the position cooperate desire punching out workpiece 5 be provided with; The utility model for embodiment in, be example all with a punching 10, a material-dropping hole 11, a magnetic element 2 and a drift 40.On template 1 die face then horizontal desire the workpiece 5 of punching out to some extent.

As shown in Figure 4, when the drift 40 of patrix 4 during towards punching 10 punching presses, drift 40 can stretch into magnetic element 2 inside by punching 10, will be brought to magnetic element 2 inside by the waste material 50 of institute's punching press on the workpiece 5 in the lump; At this moment, waste material 50 is because of being positioned at magnetic element 2 inside, thus can be subjected to the influence of magnetic element 2 magnetic attraction, and be adsorbed on (promptly as shown in Figure 5) on magnetic element 2 inwalls.Therefore, as shown in Figure 5, after drift 40 rises because waste material 50 is adsorbed by magnetic element 2, so drift 40 waste material 50 can not taken out of outside the punching 10, to reach the purpose that prevents jump-scrap.

The above only is preferred embodiment of the present utility model; be not in order to limit scope of patent protection of the present utility model; so use equivalent structure that patent spirit of the present utility model does to change such as or modification etc., all should in like manner be contained within the scope of patent protection of the present utility model.
