Abstract

The utility model provides an oblique hole punch device which comprises an upper punch holder, a driving block, a material pressing block, an installation base, a punching head and a retracting spring, wherein the driving block is installed on the upper punch holder and the installation base is contained in the material pressing block. A through hole along the punching hole direction are arranged in the installation base, and the punching head penetrates through the through hole. The upper end of the punching head separably contacts the driving block, and the retracting spring is arranged on the punching head. The oblique hole punch device has the advantages of simple structure and easy use. The utility model is especially suitable for the occasions that a manufacture component operating space is limited. In addition, a through groove is arranged on the material pressing block, and the components, such as the punching head, the installation base, etc. are all contained in the through groove of the material pressing block. Thus, the whole structure is very compact and the usage space is small.

Description

Towards the inclined hole device
Technical field
The utility model relates to mould applications, relates in particular to a kind of towards the inclined hole device in the mould applications.
Background technology
In mould applications, often need there be certain included angle between i.e. punching direction and the vertical direction at product upper punch inclined hole.Towards inclined hole the time, use hanging wedge device usually.Particularly, exactly moving both vertically up and down of patrix is converted into the banking motion of drift by hanging wedge device, thereby at product upper punch inclined hole.The hanging wedge device of standard generally includes drive block, Slave Block, driven block and some slider guides and retracting spring.
But, in some occasion, for example have in limited time in the operating space of product, be difficult to common hanging wedge device is installed in the mould, therefore need be a kind of improved towards the inclined hole device, it is simple in structure, compact and easy to use.
The utility model content
Therefore, the purpose of this utility model provides a kind of inclined hole device that dashes simple in structure, compact and easy to use.
Comprise upper bolster, drive block, binder block, mount pad, drift and retracting spring towards the inclined hole device, wherein drive block is installed on the upper bolster, mount pad is contained in the binder block, have in the mount pad along the through hole of punching direction, drift runs through this through hole, the upper end of drift contacts drive block separably, has retracting spring on drift.
, in the inclined hole device,, be installed in drive block on the upper bolster and will contact the upper end of drift and oppress drift and tilt to move downward, thereby on product, go out inclined hole this along the punching direction by the motion vertically downward of upper bolster.After having dashed inclined hole, upper bolster moves vertically upward, drive simultaneously that drive block moves upward and the upper end of leaving drift, thereby drift moves upward under the effect of retracting spring and turns back to its home position, thereby finished product is dashed the inclined hole operation.
Therefore, should be very simple and easy to use towards the inclined hole apparatus structure, the occasion that is particularly suitable for being restricted in the product operating space is used.In addition, by offer groove on binder block, parts such as drift and mount pad all are contained in the groove of binder block, thereby total is very compact, it is less to take up room.
Description of drawings
Fig. 1 is the structural representation towards the inclined hole device of the present utility model.
The specific embodiment
Be elaborated towards the inclined hole device to of the present utility model below with reference to Fig. 1.
As shown in Figure 1, should comprise upper bolster 1, drive block 2, binder block 3, mount pad 4, drift 5 and retracting spring 6 towards the inclined hole device, wherein drive block 2 is installed on the upper bolster 1, mount pad 4 is contained in the binder block 3, have in the mount pad 4 along the through hole of punching direction, drift 5 runs through this through hole, and the upper end of drift 5 contacts drive block 2 separably, has retracting spring 6 on drift 5.
Product 10 be positioned at mount pad 4 below, perpendicular to the direction of drift 5.The upper end of drift 5 protrudes in mount pad 4 upper surfaces certain-length, contacts with the upper surface of mount pad 4 when the lower compression drift 5 to prevent drive block 2.
When product 10 was carried out punching, upper bolster 1 moved vertically downward, and drove the also motion vertically downward of drive block 2 that is installed together with it.After drive block 2 moves to a certain degree will with the last end in contact of drift 5, and compressing drift 5 downward-sloping slip in the through hole of mount pad 4, thereby punching on product 10.After punching finished, upper bolster 1 and the drive block 2 that is installed on the upper bolster 1 moved vertically upward, and drive block 2 is away from the upper surface of drift 5, thereby under the elastic force effect of retracting spring 6, drift 5 moves upward and turns back to its home position.Thereby finished one punching operation of product.
Preferably, as shown in Figure 1, described mount pad 4 comprises mount pad 41 and following mount pad 42, and they are fixed together by tightening member such as screw 43 each other.Mount pad 4 adopts this split-type structural, feasible processing and easy to assembly.For example, when being assembled to mount pad 4 in the binder block 3, at first will descend mount pad 42 being fixed in the binder block 3 from binder block 3 below by tightening members such as bolts, and then will go up mount pad 41 and above binder block 3, be placed into down on the mount pad 42, be fixed together by screw 43 then.Therefore, the assembling of this mount pad 4 and dismounting are all more convenient.
In addition,, slider guide 7 is set in the through hole of last mount pad 41 preferably, is slided in through hole by this slider guide 7 in the top of drift 5 in order to help the wearing and tearing that drift 5 slides and reduces 5 pairs of mount pads of drift in the through hole of mount pad 4.Slider guide 7 can by parts such as alignment pin be removably mounted on through hole around.
In addition, in the through hole of following mount pad 42 binder slider guide 8 can be set, the lower surface of this binder slider guide 8 is pushed down product tightly, and the bottom of drift 5 is passed this binder slider guide 8 and can be slided.Therefore, directly in following mount pad 42, slides with drift 5 and to compare,, help the slip of drift 5 and minimizing descending the wearing and tearing of mount pad 42 by this binder slider guide 8; And after 5 pairs of products 10 of drift have dashed the hole, tightly push down product 10, can make things convenient for drift 5 from product 10, to withdraw from, i.e. easy-unloading by binder slider guide 8.
In addition preferably, have cavity on the top of binder slider guide 8, described retracting spring 6 is contained in this cavity, and promptly the lower end abutment of retracting spring 6 is on the diapire of cavity, and the upper end then is resisted against on the flange of drift 5, thereby reaches the effect that makes drift 5 backhauls.And this structure is compact especially.
