Description

A kind of skeleton cuts off mould

Technical field

The utility model relates to a kind of cut-out mould, and particularly a kind of skeleton cuts off mould.

Background technology

Hardware products has been widely used in various industries.Cutting method at the metallic framework of existing structure mainly is to adopt gas cutting or grinding wheel cutting.The skeleton cut surface flatness that these two kinds of cutting methods are processed is not high, need further to process to polish, and section precision (like the setting angle of 90 degree) can not guarantee.For above-mentioned deficiency, need to carry out calibration with artificial mode once more, thereby make wasting time and energy that the manufacturing of structural metal skeleton becomes.

The utility model content

For solving the technical problem that exists in the prior art, the utility model provides the skeleton that a kind of cost of manufacture is low, product percent of pass is high to cut off mould.

The utility model solves the problems of the technologies described above, and the technical scheme that is adopted is: provide a kind of skeleton to cut off mould, comprise by loam cake, base and four box bodys that sidewall surrounds; Respectively being fixed with a cross section on one relative angle of this box body is the piece of deciding of right angled triangle; Another of this box body is provided with the last motion block and following motion block that the cross section is a right angled triangle to relative angle; It is polygonal moving knife that the middle part of this box body is provided with a cross section; The edge of this moving knife is respectively equipped with and saidly decides piece, goes up the hypotenuse that motion block and following motion block are complementary, and the middle part of this moving knife is provided with the punching that is complementary with frame configuration; One sidewall of said box body is provided with one and supports the said spring of motion block down, and the said right-angle side both sides of motion block down are respectively equipped with the movable space of said moving knife, is covered with the through hole that is positioned at directly over the motion block on said.

As a preferred version, be provided with the pressure head of a column in the said through hole, this pressure head is used for transfer function in the said external pressure that goes up motion block.

As a preferred version, the cross section of said moving knife is an octagon, and the corresponding sides of said octagon moving knife equate and be parallel.

As a preferred version, said two right-angle sides of going up motion block contact with a sidewall with the loam cake of said box body respectively, and the hypotenuse of last motion block contacts with the hypotenuse coupling of said moving knife.

As a preferred version, said two hypotenuse length that the hypotenuse length of deciding piece matches greater than said moving knife.

As a preferred version, the outer wall of said box body is provided with the spring base of the said spring of a device, and this spring base is installed on horizontal direction.

As a preferred version, the said gap length of motion block right-angle side both sides down is equal to or greater than the thickness of said skeleton.

The technical scheme of the utility model is with respect to prior art, and the beneficial effect of obtaining is:

(1) goes up motion block under the effect of external force, drive the oblique motion down of moving knife, thereby the skeleton that will be arranged in advance in the moving knife punching produces relative displacement, thereby skeleton is cut off.Because external force is bigger, break time is very short, so the cross section of skeleton is smooth, need not process once more the skeleton after cutting off, and has improved the qualification rate of product and has reduced production cost.

(2) shape of moving knife can be multiple shape, like octagon, hexagon, can design according to the size and the shape of box body, reduces cost and practical effect to reach.

The specific embodiment

Specify the technical scheme of the utility model below in conjunction with accompanying drawing and embodiment.

Fig. 1 shows the generalized section that skeleton cuts off mould, and Fig. 2 shows the utility model moving knife one example schematic, and Fig. 3 illustrates an embodiment sketch map of deciding piece, and Fig. 4 illustrates motion block or following motion block one embodiment sketch map.

The described skeleton of the utility model cuts off mould, comprises box body 10, and box body 10 is by being surrounded by loam cake 11, base 12 and four sidewalls 13,14.Two

sidewalls

13,14 only are shown in Fig. 1, but are appreciated that the front and back at box body 10 also has two sidewalls, thereby surround a box body shape.On the relative angle of box body 10 each fixing cross section be the right angle trigonometry shape decide

piece

31,32, last motion block 33, time motion block 34 that a cross section is the right angle trigonometry shape respectively are set on another relative angle of box body 10.It is polygon-shaped moving knife 20 that the middle part of box body 10 is provided with a cross section; The edge of moving knife 20 is respectively equipped with and decides hypotenuse L1, L1 ', L2, the L2 ' that

piece

31,32, last motion block 33 and following motion block 34 are complementary; The middle part of moving knife 20 is provided with the punching 21 that is complementary with frame configuration, and frame configuration can be C type or other shapes; A sidewall 14 of box body 20 is provided with and supports the spring of motion block 34 down, and spring is installed in the spring base 28 and spring base 28 can be installed in the horizontal direction.The right-angle side both sides of following motion block 34 are respectively equipped with the

space

35,36 of moving knife 20 activities, and

space

35,36 width are equal to or greater than the thickness of skeleton.Loam cake 11 is provided with through hole, through hole be positioned at motion block 31 directly over, be provided with the pressure head 30 of a column in the through hole, pressure head 30 is used for the outside impulse force F of transfer function in last motion block 33.

Like Fig. 1, shown in Figure 2, the cross section of moving knife 20 is an octagon, and the corresponding sides of this octagon moving knife 20 equate and be parallel.The shape of moving knife 20 is not limited to this, and the shape of moving knife 20 can be to realize cutting off the shape of skeleton arbitrarily, like hexagon, decagon etc.Like Fig. 3, shown in Figure 4, two hypotenuse L4 length of deciding

piece

31,32 are greater than moving knife 20 and the hypotenuse L1 of hypotenuse L4 coupling, the length of L1 '.Two right-angle sides of last motion block 33 contact with a sidewall 13 with the loam cake 11 of box body 10 respectively, and the hypotenuse of last motion block 33 contacts with the hypotenuse L2 coupling of moving knife 20.

Cut off mould in the course of the work, outside impulse force F acts on the column pressure head 30, and pressure head 30 passes to motion block 33 with power.After last motion block 33 receives the effect of outside impulse force F; The hypotenuse L2 of the hypotenuse L3 of last motion block 33 through moving knife 20 moves moving knife 20 toward oblique direction down, because the length of hypotenuse L4 of decide

piece

31,32 is greater than the length of moving knife 20 hypotenuse L1, L1 ', and two right angle avris of time motion block 34 are provided with the

space

35,36 of moving knife 20 activities; And the width in

space

35,36 is greater than the thickness of skeleton; Therefore, moving knife 20 produces relative displacement with skeleton, thereby skeleton is cut off.When external force F removed, the spring after the compression recovered voluntarily, then descended motion block 34 with spring reset.

The above is merely the utility model preferred embodiment, does not limit the scope that the utility model is implemented with this. and the equivalence of being done according to the technical scheme and the description of the utility model changes and modification, all should belong to the scope that the utility model is contained.
