The utility model discloses can effectively process out the bolt construction that can prevent that the gasket from droing fast.
Description
Technical Field
The utility model relates to a thread rolling die field that bolt processing production used especially relates to a prevent bolt mold processing that gasket drops.
Background
When the bolt is used in daily life, a gasket is usually sleeved on the screw rod for improving the sealing property and the wear resistance of the bolt connection. To current bolt and gasket combination piece, generally be bolt and gasket exist alone on the existing market, wear the gasket during use to use after the bolt is made up, this kind of scheme is not convenient for assemble, and need join in marriage the gasket alone during the use, and the gasket condition of droing often takes place, the customer complains about and influences assembly efficiency, damages opponent's piece etc. causes low in production efficiency and the waste of cost.
In the prior art, a thread rolling die is generally adopted for processing bolts, and the thread rolling die is a tool for rolling threads on a thread rolling machine by using a metal plastic deformation method. In combination with the above requirements for the bolt, there is a need for a thread rolling plate capable of processing the bolt with the above effects to prevent the gasket from falling off.
Disclosure of Invention
An object of the utility model is to overcome the not enough of above-mentioned technique, provide a prevent bolt mold processing that the gasket drops, can effectively process out the bolt structure that can prevent the gasket and drop fast.
In order to realize the purpose of the utility model, the utility model adopts the technical scheme that:
the utility model provides a prevent bolt mold processing that gasket drops, includes two relative settings rub the dental lamina with the hands, its characterized in that, every rub and be provided with snap ring shaping portion and screw thread shaping portion from top to bottom on the working face of dental lamina with the hands, be formed with the straight flute line of horizontally in the snap ring shaping portion, be formed with a plurality of interval arrangement's sloted line from last to bottom in the screw thread shaping portion, the groove depth of straight flute line is greater than the groove depth of sloted line.
The utility model discloses a further improvement lies in, rub the interior refrigerant passageway of having seted up by one end to the other end of tooth board with the hands, refrigerant channel connects cooling circulation system, refrigerant passageway is the wave structure, and through the refrigerant in this refrigerant passageway circulation production cooling function, adopt the wave structure simultaneously, further improve the cooling effect.
The working steps of the bolt processing die for preventing the gasket from falling off are as follows:
A. passing a washer through the shaft portion of the bolt, the washer being positioned against the head portion of the bolt;
B. arranging the two thread rolling plates oppositely, and arranging the shaft part of the bolt between the two thread rolling plates, wherein the two thread rolling plates are tightly attached to the shaft part of the bolt;
C. make a certain thread rolling die move along the relative another thread rolling die of direction of motion of bolt axial region to the bolt axial region between two thread rolling dies is arranged in the drive rotates around self axis, utilizes snap ring shaping portion and screw thread shaping portion on the thread rolling die, makes the last annular snap ring and the screw thread that form of bolt axial region, and the external diameter of the snap ring after the shaping is greater than the internal diameter of gasket, and at this moment, the gasket is located between snap ring and the bolt head, and the gasket receives the snap ring spacing and can't follow the bolt and drop.
The utility model has the advantages that:
utilize the utility model discloses the bolt of production can prevent effectively that the gasket from droing to lead to unable assembly or to break the screw thread in assembling process, has improved that user's assembly production efficiency, product quality stability uniformity are good, bring more benefits, can the wide application in the fastener production field of bolt sub-assembly.

Fig. 2 is a schematic structural diagram of embodiment 2 of the present invention.
Fig. 3 is a schematic structural view of a bolt processed by the thread rolling die of the present invention.
In the figure: a thread rolling plate 1, a snap ring forming part 2, a thread forming part 3 and a refrigerant channel 4.
Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
As shown in fig. 1, a bolt processing mold for preventing a gasket from falling off comprises two opposite tooth rubbing plates 1, a snap ring forming part 2 and a thread forming part 3 are arranged on a working surface of each tooth rubbing plate 1 from top to bottom, a horizontal straight groove line is formed on the snap ring forming part 2, a plurality of oblique groove lines arranged at intervals are formed on the thread forming part 3 from top to bottom, and the groove depth of the straight groove line is greater than that of the oblique groove line.
The working steps of the bolt processing die for preventing the gasket from falling off are as follows:
A. passing a washer through the shaft portion of the bolt, the washer being positioned against the head portion of the bolt;
B. arranging the two thread rolling plates oppositely, and arranging the shaft part of the bolt between the two thread rolling plates, wherein the two thread rolling plates are tightly attached to the shaft part of the bolt;
C. make a certain thread rolling die move along the relative another thread rolling die of direction of motion of bolt axial region to the bolt axial region between two thread rolling dies is arranged in the drive rotates around self axis, utilizes snap ring shaping portion and screw thread shaping portion on the thread rolling die, makes the last annular snap ring and the screw thread that form of bolt axial region, and the external diameter of the snap ring after the shaping is greater than the internal diameter of gasket, and at this moment, the gasket is located between snap ring and the bolt head, and the gasket receives the snap ring spacing and can't follow the bolt and drop.
The bolt structure after molding is shown in fig. 3.
Example 2
Referring to embodiment 1, as shown in fig. 2, with the remaining features unchanged, the tooth rubbing plate 1 is provided with a refrigerant channel 4 from one end to the other end, the refrigerant channel 4 is connected to the cooling circulation system, the refrigerant channel 4 is of a wave-shaped structure, the refrigerant channel 4 generates a cooling function by flowing a refrigerant therethrough, and the wave-shaped structure is adopted to further improve the cooling effect.
It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element.
