Abstract

The utility model discloses a diagonal web member shearing mould. The diagonal web member shearing mould comprises an upper mould and a lower mould, wherein the upper mould is provided with a downward upper shearing knife, the lower mould is provided with an upward lower shearing knife; the upper shearing knife and the lower shearing knife are staggered in opposite directions and are provided with planar cutting edges and moulding slopes on the outer sides of the planar cutting edges; and the edge on the inner side of the planar cutting edge of the upper shearing knife and the edge on the inner side of the planar cutting edge of the lower shearing knife are aligned with each other. The diagonal web member shearing mould is installed on a punching machine, can quickly machine a diagonal web member with two flat ends, and has the advantages of high machining efficiency and good machining quality.

Description

The diagonal web member shearing die

Technical field

The utility model belongs to the building machinery technical field, relates to building hoist, relates in particular to the shearing die of the diagonal web member of processing building hoist standard knot.

Background technology

Building hoist is claimed construction elevator again, is a kind of employing gear, tooth bar engagement system or rope hoisting mode, makes cage make vertical or banking motion; In order to carry the building machinery of workmen, instrument, equipment and material; Other hoisting mechanism of its friendship is stable, safe and reliable, need not establish machine room or hoistway in addition, and has advantages such as easy accessibility, carrying flexibility are strong; Be widely used; Especially in alleviating workmen's labour intensity, speed up the work, increasing work efficiency, play tangible effect.

Standard knot is the vitals of building hoist.At the construction field (site), the continuous stacked formation crane through a plurality of standard knots.For guaranteeing the stable and safety of building hoist, the firm degree of standard knot is most important.The prior standard joint mainly is the frame structure that is made up of crossbeam and vertical beam, for the firm degree of standard knot further is provided, between crossbeam, also is welded with diagonal web member.Diagonal web member is a round steel pipe, and two ends are welded on the crossbeam.But find that in actual application the end face at diagonal web member two ends is a toroidal, it is when welding with crossbeam, and contact-making surface is smaller, thus cause and crossbeam between bonding strength not enough, the risk of fracture is arranged.

Afterwards, it is flat-shaped that applicant's inventor expects using the two ends with diagonal web member to be pressed into, and can increase the welding contact area with crossbeam like this, thereby improve weld strength.But, up to the present, also do not occur a kind ofly can the diagonal web member two ends being cut into flat-shaped shearing die.

The utility model content

For this reason, the utility model technical problem to be solved provides and a kind ofly can fast the diagonal web member two ends be cut into flat-shaped shearing die, to overcome the deficiency that prior art exists.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of diagonal web member shearing die; It is characterized in that: comprise upper die and lower die; Said mold has the last shear knife of downward direction, and the oriented down cut cutter of going up direction of said bed die is saidly gone up the setting of staggering in the opposite direction of shear knife and down cut cutter; And all have the plane cutting edge and be positioned at moulding inclined-plane, the plane cutting edge outside, align each other in the inside edge of the plane cutting edge of said cutting edge inside edge, plane of going up shear knife and said down cut cutter.

In the specific embodiment of the utility model; Said upper die and lower die include base plate, are fixed on the holder on the base plate; Said upward shear knife and down cut cutter afterbody all have stationary body; Have fixed groove on the said holder, the stationary body of said upward shear knife and the stationary body of down cut cutter are all through in the fixed groove that is bolted to holder.

Adopt above-mentioned technology, the shearing die of the utility model is installed in just can to process two ends apace on the press machine be flat-shaped diagonal web member, have working (machining) efficiency height, advantage that crudy is good.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated:

Fig. 1 is the structural representation of the utility model;

Among the figure:

The 100-patrix, the last shear knife of 110-, 200-counterdie, 210-down cut cutter, 300-plane cutting edge, 310-moulding inclined-plane, 400-base plate, 410-holder, 411-fixed groove, 420-stationary body, 500-bolt, 10-steel pipe.

The specific embodiment

As shown in Figure 1, the diagonal web member shearing die of the utility model comprises patrix 100 and counterdie 200.

Wherein, patrix 100 has the last shear knife 110 of downward direction, and counterdie 200 has the upwards down cut cutter 210 of direction.The setting of staggering in the opposite direction of last shear knife 110 and down cut cutter 210; And all having plane cutting edge 300 and be positioned at moulding inclined-plane, plane cutting edge 300 outside 310, aligns each other in the inside edge of plane cutting edge 300 inside edges of last shear knife 110 and the plane cutting edge 300 of down cut cutter 210.

Particularly; Patrix 100 includes base plate 400, is fixed on the holder 410 on the base plate 400 with counterdie 200; And last shear knife 110 all has stationary body 420 with down cut cutter 210 afterbodys; On holder 410, have fixed groove 411, and the stationary body of last shear knife 110 and the stationary body of down cut cutter 210 are fixed in the fixed groove 411 of holder 410 through bolt 500 all.

More than be exactly the diagonal web member shearing die of the utility model, as shown in Figure 1 again, during this shearing die work; Counterdie 200 static, patrix 100 punching presses downwards fast; The plane cutting edge of last shear knife 110 and the plane cutting edge of down cut cutter 210 can be cut off steel pipe 10 fast, and form a bit of flat-shaped structure, and when shearing; The moulding inclined-plane in the outside can strike out the inclined-plane with the termination, makes the final diagonal web member termination that forms carry out the transition to flat-shaped gradually from the circle shape.

Through above-mentioned detailed description, can find out that the diagonal web member shearing die of the utility model is installed in, and just can to process two ends apace on the press machine be flat-shaped diagonal web member, have working (machining) efficiency height, advantage that crudy is good.

But; Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model, as long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
