Abstract
The invention discloses a method for machining screw grooves. A screw semi-finished product is preformed. The semi-finished product comprises a screw cap, a threaded rod and an intermediate body between the screw cap and the threaded rod, which are integrally formed. The semi-finished product is disposed in a thread rolling unit which comprises a fixed thread plate and a movable thread plate, a thread is arranged at corresponding positions of the fixed thread plate and the movable thread plate respectively, and the intermediate body is disposed on the threads. A groove is machined in the intermediate body each time the movable thread plate reciprocates on the fixed thread plate. According to the method, the manufacture process is simple, the production efficiency is high, and screws which can be in tight connection with buckles and are not prone to loosing can be manufactured.
Description
Technical field
The present invention relates to the processing method field of screw, especially relate to a kind of method that processes groove on screw.
Background technology
On circuit board, some components and parts need to be fixed with screw, such as the central processing unit fixture on computer motherboard and radiator etc.Screw belongs to a kind of locking part, can cooperatively interact and use with screw, various parts are combined into an assembly, and can make part easily assembling or dismounting.
General screw mainly comprise an integrated blind nut, the intermediate connected with this blind nut and can with the threaded rod of the relative combination of screw.When existing this screw is connected with latch closure, directly latch closure to be fixed on the outer surface of screw intermediate, because the outer surface of intermediate is shiny surface, so when latch closure and screw are used in conjunction with, what be often connected is not very tight, is easy to occur loosening phenomenon.
For this reason, we have carried out innovative design on the basis of this screw, by process a groove on the intermediate of this screw, thereby make to be connected between latch closure and screw tightr, are convenient to better part be carried out fastening, are difficult for loosening.Owing to processing this groove, there is no efficient manufacturing process, therefore the application of the screw after this improvement has been formed to restriction.
Summary of the invention
The object of the invention is to overcome the defect of prior art, a kind of processing method of screw groove is provided, manufacturing process is simple, production efficiency is high.
For achieving the above object, the present invention proposes following technical scheme: a kind of processing method of screw groove, comprises the following steps:
Step 1, molds screw semi-finished product, and described semi-finished product comprise integrated blind nut, threaded rod and the intermediate between described blind nut and threaded rod;
Step 2, is placed in thread rubbing device by described semi-finished product, and described thread rubbing device comprises fixedly dental lamina and movable dental lamina, and the correspondence position of described fixedly dental lamina and movable dental lamina is provided with tooth line;
Step 3, described movable dental lamina back and forth moves once on described fixedly dental lamina, and described semi-finished product are pushed, and processes a groove on described semi-finished product.
Preferably, in described step 2, described intermediate is placed between described tooth line.
Described tooth line is protruding cuboid, for the outer surface at described intermediate, processes a cylindrical groove.
Described groove is positioned on described intermediate, for being connected with latch closure.
The width of described groove equals the width of described tooth line, and the degree of depth of described groove equals the height of described tooth line.
The invention has the beneficial effects as follows: by fixedly tooth line being set on dental lamina and movable dental lamina, thereby on the intermediate of screw, process corresponding groove, movable dental lamina only need fixedly back and forth move once on dental lamina, can process a groove, manufacturing process is simple, production efficiency is fast, can produce and can closely be connected with latch closure, be difficult for loosening screw simultaneously.

The specific embodiment
Below in conjunction with accompanying drawing of the present invention, the technical scheme of the embodiment of the present invention is carried out to clear, complete description.
The present invention has disclosed a kind of processing method of screw groove, for process the groove in mating connection with latch closure on screw.
As shown in Figure 1, the processing method of disclosed a kind of screw groove, comprises following step:
The first step, molds screw semi-finished product in advance, and the semi-finished product after processing comprise integrated blind nut 1, threaded rod 3 and the intermediate 2 between described blind nut 1 and threaded rod 3.Detailed process is: first, first section cutting goes out stock; Secondly, then each stock punch forming is gone out to blind nut 1, and punch forming goes out intermediate 2; Finally threading molds threaded rod 3 again.
Second step, described semi-finished product are placed in to thread rubbing device 4, as shown in Figure 2, wherein said thread rubbing device 4 comprises fixedly dental lamina 41 and movable dental lamina 42, described movable dental lamina 42 moves reciprocatingly on described fixedly dental lamina 41, the correspondence position of described fixedly dental lamina 41 and movable dental lamina 42 is respectively arranged with tooth line 42, and described tooth line 42 is protruding cuboid.
Detailed process is: described semi-finished product are fed in described thread rubbing device 4 through feeding device (not shown), add man-hour, described intermediate 2 is placed between described fixedly dental lamina 41 and described movable dental lamina 42, and described intermediate 2 is placed on described tooth line 43, and described blind nut 1 is positioned at outside described thread rubbing device 4.
The 3rd step, described movable dental lamina 42 back and forth moves once on described fixedly dental lamina 41, and described intermediate 2 is carried out to extruding in a week, processes a cylindrical groove 5 on the position of the relatively described tooth line 43 of described intermediate 2.
Carry out before threading, described movable pressing board 42 and described fixation clip 41 be arranged in parallel up and down, and described centre 2 bodies are placed between described fixedly dental lamina 41 and described movable dental lamina 42; While carrying out threading, described movable pressing board 42 moves relative to described fixation clip 41, in moving process, described intermediate 2 is pushed, and processes a groove 5 on described intermediate 2; After threading completes, described movable pressing board 42 resets on the position parallel with described fixation clip 41, and next semi-finished product are carried out to threading processing, and the finished product after processing collects receipts because gravity drops in collection receipts case (not shown) naturally.
The width of the groove 5 processing equals the width of described tooth line 43, and the degree of depth of described groove 5 equals the height of described tooth line 43.
Screw after processing as shown in Figure 3, on original half-finished architecture basics, processes a groove 5 at described intermediate 2 near one end of described threaded rod 3, in mating connection with latch closure.
Technology contents of the present invention and technical characterictic have disclosed as above; yet those of ordinary skill in the art still may be based on teaching of the present invention and announcements and are done all replacement and modifications that does not deviate from spirit of the present invention; therefore; protection domain of the present invention should be not limited to the content that embodiment discloses; and should comprise various do not deviate from replacement of the present invention and modifications, and contained by present patent application claim.
