Description
Technical field
The invention belongs to automobile-used technical field of fastening, relate to automobile-used bolt, be specifically related to a kind of band and scrape paint tooth
Bolt processing dental lamina.
Background technology
Bonding bolt major part is used for the connection connecting on automobile between electrical equipment, and being screwed into by bolt, with right
Hands part forms interference fit, scrapes the paint inside opponent's part, plays the effect of conduction, and traditional taking
Iron bolt uses the design of thread middle impression, and traditional technique uses punch forming, and depth of cup is unstable,
Quality stability is poor, often has bonding unstable, causes bonding bad connection, car etc. has occurred to burn not
Good phenomenon.
Summary of the invention
The present invention is unstable in order to solve conventional traditional handicraft impression size, the phenomenon of bad earth, then
Use cold extrusion one-shot forming technique, mould ensure product size precision.
The band that the present invention processes is scraped paint tooth bolt and is included integrated bolt head and shank of bolt；Described bolt
The cylinder of bar is provided with matching thread；The middle part of described matching thread is provided with scrapes paint tooth section；Described scraping paints tooth section
Thread is that both sides are equipped with the trapezoidal of projection, scrapes the district between two projections of paint tooth section adjacent thread opposite side
Territory is for scraping paint interference region；Scrape the thread big footpath thread path more than matching thread of paint tooth section；The post of shank of bolt
Face head is taper surface；Described taper surface offers scrapes paint bath；The described handing-over scraping paint bath and taper surface
Place forms blade face.
The present invention includes dynamic and static screw plate；All it is machined with a plurality of inside described dynamic and static screw plate and arranges
The thread rolling raised line put；The axis of described thread rolling raised line and horizontal angle are 20～25 °；Near bottom
Article 4～6, the thread rolling raised line port of export offers projection mounting groove；The outer end of described projection mounting groove is open, and flute length is
0.1～0.2 times of processing dental lamina length；The projection mounting groove of dynamic and static screw plate is oppositely arranged；Quiet screw plate
Projection mounting groove in fix two along bolt direction of transfer spacing arrange group of bumps；Described group of bumps bag
Include three projections of vertically equidistant placement；The height little 1 of the aspect ratio thread rolling raised line of described projection～
2mm。
The invention have the benefit that
1, the band that the present invention processes is scraped paint tooth bolt and is provided with and scrapes paint tooth section and blade face, and blade face scraped falls
Impurity inside opponent's part and the bulk paint of inner surface, scrape paint tooth section scraped and fall the oil in opponent's part screw thread
Paint, it is achieved metallic matrix connects.
2, the present invention use cold extrusion one-shot forming technique to ensure band scrape paint tooth bolt product size precision,
Steady quality so that band is scraped scraping of paint tooth bolt and painted tooth section and matching thread together molding, reduces operation, joint
About cost.
Accompanying drawing explanation
Fig. 1 is that paint tooth bolt schematic diagram scraped by the band that the present invention processes.
Fig. 2 be the band that the present invention processes scrape paint tooth bolt scrape paint tooth section scrape paint interference region schematic diagram.
Fig. 3 is the structural perspective of the present invention.
Fig. 4 is the bolt semi-finished product schematic diagram in the present invention after cold-heading.
Detailed description of the invention
With embodiment, the present invention is described in detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, paint tooth bolt scraped by the band that the present invention processes includes integrated bolt head and bolt
Bar；The cylinder of shank of bolt is provided with matching thread 1；The middle part of matching thread 1 is provided with scrapes paint tooth section 2；Scrape paint tooth section
Thread be both sides be equipped with projection trapezoidal, scrape paint tooth section adjacent thread opposite side two projections between
Region is for scraping paint interference region 8；Scrape paint interference region 8 scraped and fall the paint in opponent's part screw thread, it is achieved Metal Substrate
Body connects；Scrape the thread big footpath thread path more than matching thread 1 of paint tooth section 2, as shown in Figure 2；Shank of bolt
Cylinder head be taper surface；Taper surface offers scrapes paint bath 3；Scrape the junction formation of paint bath 3 and taper surface
Blade face 4.
As it is shown on figure 3, paint tooth bolt processing dental lamina scraped by band, including dynamic and static screw plate；In dynamic and static screw plate
Side is all machined with a plurality of thread rolling raised line 5 being arranged side by side；The axis of thread rolling raised line 5 and horizontal angle are 20
°；Five thread rolling raised line ports of export near bottom offer projection mounting groove 6；The outer end of projection mounting groove is open,
Flute length is 0.2 times of processing dental lamina length；The projection mounting groove of dynamic and static screw plate is oppositely arranged；Quiet screw plate
Projection mounting groove in fix two along bolt direction of transfer spacing arrange group of bumps 7；Group of bumps 7 includes edge
Three projections of vertical direction equidistant placement；The little 1mm of height of the aspect ratio thread rolling raised line of projection.
Use this band scrape paint tooth bolt processing dental lamina processing bolt detailed process as follows:
1, as shown in Figure 4, bolt cold-heading goes out shank of bolt cylinder, becomes bolt semi-finished product.Bolt semi-finished product
Shank of bolt cylinder head is taper surface；Taper surface offers scrapes paint bath；Scrape the junction shape of paint bath and taper surface
Become blade face.
2, bolt semi-finished product enter into thread rolling track after feeding vibrating disk vibrates, and by thread rolling track enter dynamic,
In the gap of quiet screw plate.
3, dynamic and static screw plate carries out thread rolling to bolt semi-finished product.Quiet screw plate maintains static, dynamic screw plate with
Quiet screw plate is oppositely arranged and moves back and forth along parallel quiet screw plate direction；Shank of bolt cylinder is in dynamic and static thread rolling
Matching thread is formed, as shown in Figure 2 under the mutual rubbing of thread rolling raised line 5 of plate；The middle part of shank of bolt cylinder is quiet
Formed under group of bumps 7 rubbing of screw plate and scrape paint tooth section.
4, the bolt after thread rolling being carried out heat treatment, heat treatment is quenched or carburizing, makes the hardness number of bolt reach
To requiring.
5, the bolt after heat treatment being carried out surface process, surface is processed as at plating zinc on surface, coating or phosphatization
Reason.
