Abstract
The invention discloses a structure of a press brake band assembly and a manufacturing method thereof. A clamp and a pull rod base are manufactured by adopting the cold pressing mode respectively, wherein a protruding opening of the clamp and a protruding opening of the pull rod base are guaranteed to have a proper opening degree during manufacture. A circular through hole is formed in the middle of a cuboid opposite to the protruding opening of the pull rod base; one end of the pull rod penetrates an inner cavity of the pull rod base from the outside, and the pull rod is fixed on the pull rod base through a nut. Two ends of a steel band are clamped in the protruding opening of a clamp band and the protruding opening of a pull rod base band; and the steel band is fixed on the clamp and the pull rod base through a clamp rivet and a pull rod base rivet; and a friction band is fixed on the steel band through a steel band rivet.
Description
Technical field
The present invention relates to a kind of structure and manufacture method thereof of press brake band assembly, refer in particular to the assembly structure and the manufacture method thereof of the brake band of rigid clutch pressing machine, belong to the metal forming machinery technical field.
Background technology
At present, in rigid clutch pressing machine, the assembly structure of brake band is made up of critical pieces such as chuck, base of the carrier head, steel band, friction band, draw-bar seat, draw-bar seat clamping plate, pull bars, in the brake band assembly of this structure, not only parts are more relatively, and all be to adopt the method manufacturing of machining to form as chuck, base of the carrier head, draw-bar seat, the draw-bar seat clamping plate of attaching parts, this manufacture method not only complex process, inefficiency, waste of raw materials is serious but also cost product is also higher, is unfavorable for the market competition requirement of product.
Summary of the invention
The objective of the invention is to: structure and manufacture method thereof that a kind of press brake band assembly is provided, overcome the more relatively defective of parts that existing forcing press assembly exists, especially all be the method that adopts machining for chuck, base of the carrier head, draw-bar seat, the draw-bar seat clamping plate that overcome as attaching parts, because this manufacture method causes complex process, inefficiency, waste of raw materials is serious and cost product is also higher, be unfavorable for the defective of the market competition requirement of product.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of structure of press brake band assembly, it is made up of chuck, chuck rivet, steel band rivet, friction band, steel band, draw-bar seat rivet, draw-bar seat, nut, pull bar.The cross section of described chuck is the cylinder of the outstanding opening of band, its transverse cross-sectional profile of described draw-bar seat is the outstanding opening cuboid of band, the centre of giving prominence to the cuboid on opening opposite at draw-bar seat has circular through hole, one end of pull bar from outside penetrate the internal cavities of draw-bar seat, with nut with pull bar be fixed on draw-bar seat above.In the opening that the two ends of described steel band are clamped in the outstanding opening of chuck band respectively and the draw-bar seat band is outstanding, and be fixed on described chuck and the draw-bar seat with chuck rivet, draw-bar seat rivet respectively, described friction band is fixed on above the steel band with the steel band rivet.The manufacture method of press brake band assembly of the present invention is characterized in that: described chuck and draw-bar seat, adopt the manufacturing of cold-stamped method to form.
Beneficial effect: the critical piece in a kind of press brake band assembly structure of the present invention, because the method manufacturing of having adopted cold stamping to be shaped, so, overcome the more relatively defective of parts that existing forcing press assembly exists, especially all be the method that adopts machining for chuck, base of the carrier head, draw-bar seat, the draw-bar seat clamping plate that overcome as attaching parts, because this manufacture method causes complex process, inefficiency, waste of raw materials is serious and cost product is also higher, be unfavorable for the defective of the market competition requirement of product.
