Abstract

Provided is a penetrating and cutting rivet. The penetrating and cutting rivet is composed of a rivet body and a rivet core. A cap brim is arranged at one end of the rivet body, a pipe body is arranged at the other end of the rivet body, and an inner cavity of the rivet body is set to be a through hole; a rivet core cap head is arranged at one end of the rivet core, and a rivet core rod is arranged at the other end of the rivet core; a counter bore is formed in the rivet core cap head, and the end face of the counter bore is provided with a penetrating and cutting edge; the river core rod penetrates through the rivet body from one end of the pipe body and is matched with the rivet body together. When flexible material cushions and non-metallic materials used for sealing are clamped among riveting workpieces which are two or more layers of metal plates with preset holes, the process that the original flexible material cushions and the non-metallic materials need to be processed additionally is removed, the problem that the flexible material cushions are difficult to process is solved, the perforating and riveting can be finished at a time, and the purpose of connecting and fixing the riveting workpieces is achieved. The labor intensity of operation workers is relieved greatly, the production cost is lowered greatly, and the production efficiency is improved.

Description

Wear and cut rivet

Technical field

The utility model relates to wear cuts rivet, and it can be bored a hole and rivet once and complete.Be applicable to the fields such as panel beating, bin, furniture, door and window, air channel, automobile, train, shipping container, building.

Background technique

Self-plugging rivet is widely used in the occasion of the occasion, particularly inconvenient two-sided riveted joint that need to be connected and fixed.

At present, when quilt riveted joint workpiece is preset porose two-layer or stacked conducting plate, when the sheet metal therebetween is useful on the flexible material pad of sealing, as shown in Figure 5, there are the following problems in work progress: in actual production, the morpheme size of the preset holes of two-layer or stacked conducting plate can be controlled, but middle clamping Stamping Steel Ribbon is the flexible material that is difficult to finalize the design, if also preset riveted holes, its hole are difficult to the preset holes contraposition with sheet metal.The production technology of generally taking on-the-spot boring to coordinate both at home and abroad at present.At first, this method of construction has increased by a procedure, has increased human cost, has reduced manufacturing efficiency; Secondly, this production technology has been brought great production difficulty, because flexible material is resilient, when drill bit drills flexible material, then after withdrawing from, this hole is namely closed voluntarily, and to pass this hole just very difficult again without wearing the rivet of cutting function like this, manufacturing efficiency is very low, and the operator is also wasted time and energy.The technique that adopts the thorn hole rivet is also arranged, band taper pricker on its blind rivet or cap head, but in the actual process of using due to its conical design, cause flexible material be stretched to the periphery in hole and hold cone tightly, produce huge frictional force, all more difficult than Drilling operation during construction.

Summary of the invention

The purpose of this utility model will provide to wear exactly cuts rivet, it can overcome the existing the problems referred to above of prior art, the purpose of this utility model is to realize like this, wear and cut rivet, formed by rivet body and blind rivet, it is characterized in that: described rivet body one end is provided with shade, and the other end is set to body, and inner chamber is set to through hole; Described blind rivet one end is provided with blind rivet cap head, and the other end is provided with the blind rivet bar; Be provided with counterbore in described blind rivet cap head, the end face of counterbore is provided with wears the cutting blade mouth; The blind rivet bar penetrates rivet body and cooperatively interacts together from an end of body.

Described outer surface of tube body can be set to drum type, straight type and other shape;

The hole depth length of described counterbore can be adjusted according to requirements;

The outer round surface of described blind rivet cap head can be arranged to and wear butt to identical male and fomale(M﹠F) or smooth surface.

The utility model is while accompanying for the flexible material pad that seals and nonmetallic material between preset porose two-layer or stacked conducting plate at the riveted joint workpiece, reduce former flexible material pad and nonmetallic material and needed the operation of processing separately, solved the problem of flexible material pad processing difficulties, perforation and riveted joint are once completed, reached the purpose that is connected and fixed the riveted joint workpiece.Greatly reduce operator's labor intensity and cost of production, improved manufacturing efficiency.

1. blind rivet bar, 2. shade, 3. rivet body, 4. solid base, 5. counterbore, 6. blind rivet cap head, 7. wear the cutting blade mouth, 8. male and fomale(M﹠F), 9. riveted joint workpiece, 10. flexible material pad, 11. pressing plates, 12 Riveting Tools.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing;

Wear and cut rivet, rivet body 3 and blind rivet, consisted of, it is characterized in that: described rivet body 3 one ends are provided with shade 2, and the other end is set to body, and inner chamber is set to through hole; Described blind rivet one end is provided with blind rivet cap head 6, and the other end is provided with blind rivet bar 1; Be provided with counterbore 5 in described blind rivet cap head 6, the end face of counterbore 5 is provided with wears cutting blade mouth 7; Blind rivet bar 1 penetrates rivet body 3 and cooperatively interacts together from an end of body.

The hole depth length of described counterbore 5 can be adjusted according to requirements;

The outer round surface of described blind rivet cap head 6 can be arranged to and wear butt to identical male and fomale(M﹠F) 8 or smooth surface.

Embodiment:

As Fig. 1, Fig. 3, shown in Figure 5, process simultaneously preformed hole after pressing plate and riveted joint Work-sheet pressing, guarantee the concentricity of preformed hole, then put the flexible material pad between pressing plate and riveted joint workpiece; The blind rivet bar is penetrated rivet body from an end of body, the blind rivet bar is inserted Riveting Tool rifle mouth, again blind rivet cap head is aimed at the preformed hole on pressing plate, and make and wear the cutting blade mouth and vertically compress the flexible material pad, pushing away before the application of force, wear the cutting blade mouth and cut and wear the flexible material pad, is staking after blind rivet cap head compacting riveted joint workpiece, blind rivet cap head, part body, pass pressing plate, flexible material pad and riveted joint workpiece and be locked together.Owing to being provided with counterbore in blind rivet cap head, the counterbore end face is designed with wears the cutting blade mouth, is the annular edge of a knife, and effective for cutting flexible material pads such as wearing rubber, otch is smooth smooth; Counterbore plays the bits effect of holding; Blind rivet cap head outer round surface is provided with and wears butt to identical male and fomale(M﹠F), so wearing cut is with narrow, reduced significantly surface friction drag, blind rivet cap head in construction, is cut easily and is worn the flexible material pad, and the rivet body follow-up penetrates and is close to, instant enforcement riveted, thereby removed the drilling operating of the other processing flexibility material cushion of prior art need from, solved the problem of flexible material pad boring difficulty, significantly improved manufacturing efficiency.
