Abstract
A die for manufacturing a lock screw comprises a left die plate (2) and a right die plate (3). Two opposite faces of the left die plate (2) and the right side plate (3) are respectively provided with a thread groove which can form threads of the locking screw (1) through die pressing. The thread groove in the left die plate (2) and the thread groove in the right die plate (3) respectively comprise a starting section (I) and a locking section (II). Each starting section (I) is a normal thread groove body. The portions, in the locking sections (II), of the thread grooves are of a structure that the diameter (d) of the thread root of each locking section (II) formed through die pressing is larger than the diameter (h) of the root of the portion, in the starting sections (I), of the locking screw (1), the diameter (d) of the root of the portion, in the locking sections (II), of the locking screw (1) gradually increases, and the included angle (a) between the bottom face of the root of the portion, in the locking sections (II), of the locking screw (1) in the axial profile projection of the locking screw (1) and the axial center line of the locking screw (1) ranges from 5 degrees to 6 degrees. The die for manufacturing the lock screw has the advantages that the screw with the special threads is machined, the screw and a nut can not be disengaged after being screwed together, and the machining requirements are met.
Description
Technical field
The utility model relates to a kind of mould, especially refers to a kind of for making the mould of lock screw.
Background technology
Existing a kind of patent No. is that the Chinese utility model patent that CN201020216928.0 name is called a < < screw plate > > discloses a kind of screw plate, it is assemblied on thread rolling machine, comprise substrate and thread rolling face, on described thread rolling face, offer most thread rolling grooves, the bottom of described thread rolling groove offers chip pocket, and the bottom of described thread rolling groove is provided with circular arc molding district in the both sides of chip pocket, the circular arc in described arc forming district is R0.4～0.6, above-mentioned screw plate arranges circular arc molding district and chip pocket in thread rolling trench bottom, can make unnecessary scrap fall into chip pocket at thread rolling groove top, convenient processing, and part profile of tooth rolls into after shape through rubbing with the hands, in tooth top both sides, retain arc chord angle, not only simple in structure, processing cost is low, and working (machining) efficiency is high, the uniformity, high conformity.Yet this screw plate can only be processed conventional tooth form, and can not process the screw thread of tight screw, so the structure of this screw plate also needs further improvement.
Utility model content
Technical problem to be solved in the utility model is that a kind of processing ease, easy to process for making the mould of lock screw is provided for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above adopted technical scheme: this is for making the mould of lock screw, comprise left template and right template, it is characterized in that: on the described left template two sides relative with right template, be respectively arranged with the thread groove that the die of lock screw can be extruded, thread groove in left template and right template comprises respectively the initial segment and locking section, described the initial segment is normal thread groove, in described locking section, the structure of thread groove is: the locking section screw root diameter that mold pressing goes out is greater than the root diameter of the lock screw of the initial segment, in described locking section, the root diameter of lock screw is for increasing gradually, and the bottom surface at the bottom of the locking section tooth in the axial section projection of described lock screw in lock screw and the angle between lock screw longitudinal center line are 5 °～6 °.
As improvement, the width in lock screw locking section at the bottom of lock screw tooth is greater than the spacing at the bottom of lock screw tooth in the initial segment.
Improve, the normal thread groove of lock screw the initial segment can be preferably 1～3 tooth again.
Improve, the width in lock screw locking section at the bottom of lock screw tooth becomes large gradually with the increase of root diameter again.
Compared with prior art, the utility model adopts that on the described left template two sides relative with right template, be respectively arranged with can be by the thread groove of the die extrusion of lock screw, thread groove in left template and right template comprises the initial segment and locking section, described the initial segment is normal thread groove, in described locking section, the structure of thread groove is: the locking section screw root diameter that mold pressing goes out is greater than the root diameter of the lock screw of the initial segment, in described locking section, the root diameter of lock screw is for increasing gradually, and the bottom surface at the bottom of the locking section tooth in the axial section projection of described lock screw in lock screw and the angle between lock screw longitudinal center line are 5 °～6 °.This advantage is: the screw thread Bottom of Thread change in shape after processing, and ridge height changes, variable in distance between ridge, can process the screw with special thread, screw and nut are not screwed up can get loose, and reaches and meets process requirements, because this mould is disposable machine-shaping lock screw, so manufacturing procedure is simple, process time is short, effectively improves working (machining) efficiency, can reduce the wearing and tearing in machine process simultaneously, the rate of reducing the number of rejects and seconds, saves production cost.
