Abstract
The invention relates to a method for manufacturing a hexagonal all-plastic corrosion-resistant bolt. The method comprises the following steps of: (a) molding blanks of a bolt body (1) and a nut (2) on an injection molding machine; (b) putting the molded blank of the bolt body (1) on a thread rolling machine for thread rolling, and machining a section of an external thread (11) at the front end of the blank of the bolt body (1); and (c) putting the molded blank of the nut (2) on a nut tapping machine for tapping, and machining an internal thread which is matched with the external thread (11) of the bolt body (1) on an inner bore of the blank of the nut (2). The process is simple and convenient to operate, the surface of the bolt is smooth without burr, the flatness is high, the screw-thread fit accuracy is high, and the rejection rate of a finished product is reduced.
Description
Technical field
The present invention relates to bolt and make field, the manufacturing approach of the overall plastic anticorrosion bolt of particularly a kind of hexagonal.
Background technology
Bolt is a connection standard component the most frequently used in the present industry, and application is very extensive, and except traditional metal bolts, the plastic bolt of various models is also used in a lot of fields.Plastic bolt all is to process with engineering plastics, and manufacturing process is very different with metal bolts, and the manufacturing of present plastic bolt all is the one-shot forming of single pass injection machine, though convenient, there are many problems, not high like accuracy of thread, jagged; Cooling can cause dimension shrinks after the high-temperature injection moulding, possibly cause the threaded engagement error to enlarge occurrence of waste.
Summary of the invention
Technical problem to be solved by this invention provides the manufacturing approach of the overall plastic anticorrosion bolt of a kind of hexagonal, and technology is simple, and the surface is not crude, no burr, and finish is high, and percent defective reduces.
The technical solution adopted for the present invention to solve the technical problems is: the manufacturing approach of the overall plastic anticorrosion bolt of a kind of hexagonal is provided, and concrete operating procedure is following:
(a) blank through mould molding bolt body and nut on injection machine;
(b) blank of the bolt body after the moulding is placed on carries out rolled thread on the diaxon screw-rolling machine, at one section external screw thread of front end processing of the hair of bolt body;
(c) blank of the nut after the moulding is placed on carries out tapping processing on the tapper, process the internal thread that the external screw thread with bolt body matches at the endoporus of the blank of nut.
The used material of described bolt body and nut is PVC plastics or Maranyl or polyvinylidene fluoride plate or polypropylene material.
Beneficial effect
The present invention relates to the manufacturing approach of the overall plastic anticorrosion bolt of a kind of hexagonal, technology is simple, and is easy to operate, can guarantee that the bolt surface is barren rough, no burr, and finish is high, threaded engagement precision, the percent defective of reduction finished product.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Shown in Fig. 1-4, embodiment of the present invention relates to the manufacturing approach of the overall plastic anticorrosion bolt of a kind of hexagonal, and concrete operating procedure is following:
(a) blank (as shown in Figure 2) through mould molding bolt body 1 and nut 2 on injection machine;
(b) blank of the bolt body after the moulding 1 is placed on carries out rolled thread on the diaxon screw-rolling machine, at one section external screw thread 11 of front end processing of the hair of bolt body 1; (as shown in Figure 3)
(c) blank of the nut after the moulding 1 is placed on carries out tapping processing on the tapper, process the internal thread that the external screw thread 11 with bolt body 1 matches at the endoporus of the blank of nut 1.
Claims (2)
1. the manufacturing approach of the overall plastic anticorrosion bolt of hexagonal, concrete operating procedure is following:
(a) blank through mould molding bolt body (1) and nut (2) on injection machine;
(b) blank of the bolt body after the moulding (1) is placed on carries out rolled thread on the diaxon screw-rolling machine, at front end processing one section external screw thread (11) of the hair of bolt body (1);
(c) blank of the nut after the moulding (1) is placed on carries out tapping processing on the tapper, process the internal thread that the external screw thread (11) with bolt body (1) matches at the endoporus of the blank of nut (1).
