Abstract
The utility model discloses a thread rolling die comprising a thread rolling die body. A plurality of grooves are formed in the upper surface of the thread rolling die body, a thread rolling part used for thread rolling is inserted into each groove, and each thread rolling part is detachably and fixedly connected with the thread rolling die. The thread rolling die has the advantages of long service life, detachability, low cost and high generalization performance.
Description
Technical field
The utility model relates to a kind of thread machining device, and more particularly, it relates to a kind of screw plate.
Background technology
Screw plate, for two square masterplates above thread rolling machine, is divided into two, and one is long and the other is short, has tooth line above, for the mould that extrusion modling is screw thread to screw light nail.
At present, the screw plate on market, comprises screw plate body, and screw plate body upper surface is provided with tooth line, and embossing and screw plate body are wholely set, and the easy fracture when work of tooth line can make whole screw plate not use, and causes waste and increases cost.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of screw plate, has long service life, and detachable, cost is low, the feature that generalization is high.
For achieving the above object, the utility model provides following technical scheme:
A kind of screw plate, comprise screw plate body, described screw plate body upper surface is provided with several grooves, in described several grooves, be all inserted with the thread rolling part for thread rolling, described thread rolling part is tabular, its bottom is inserted in groove and coordinates with groove is seamless, its top is provided with tooth line, the bottom sidewall of several described thread rolling parts all offers through hole, described screw plate body sidewall runs through and is provided with the connecting hole being connected with through hole, in described connecting hole, be inserted with for running through the pin of the through hole of connecting hole and some thread rolling parts, the precision of the sidewall of described groove and thread rolling part sidewall is all made as IT6 degree.
By adopting technique scheme, thread rolling part is plugged in groove, and be detachably fixedly connected with screw plate body, after the fracture of thread rolling part, thread rolling part is disassembled, ressemble a standby thread rolling part, screw plate body just can normally be used again, reduce costs, and screw plate body long service life is longer, there is higher generalization.By adopting technique scheme, thread rolling part and the seamless link of screw plate body, on the one hand, guarantee the hardness of screw plate body, on the other hand, prevent that thread rolling part from rocking and increasing the frequency of fracture in groove, pin is inserted in connecting hole and through hole, further connect thread rolling part and screw plate body, increase the power that thread rolling part can bear.By adopting technique scheme, through reality test proof, the above-mentioned optimal parameter that is set to this setting, had both guaranteed the precision of assembling, and seamless link, at utmost saves again manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of screw plate embodiment of the utility model;
Fig. 2 is the side view of a kind of screw plate embodiment of the utility model;
Fig. 3 is the installation diagram of a kind of screw plate embodiment of the utility model.
In figure: 1, screw plate body; 11, groove; 12, connecting hole; 13, pin; 2, thread rolling part; 21, through hole; 22, tooth line.
The specific embodiment
Referring to figs. 1 through Fig. 3, a kind of screw plate embodiment of the utility model is described further.
A kind of screw plate, comprise screw plate body 1, described screw plate body 1 upper surface is provided with several grooves 11, the interior thread rolling part 2 being all inserted with for thread rolling of described several grooves 11, described some thread rolling parts 2 are all detachably fixedly connected with screw plate body 1, thread rolling part 2 is plugged in groove 11, and be detachably fixedly connected with screw plate body 1, after 2 fractures of thread rolling part, thread rolling part 2 is disassembled, ressemble a standby thread rolling part 2, screw plate body 1 just can normally be used again, reduce costs, and screw plate body 1 long service life is longer, (screw plate body 1 and thread rolling part 2 are made by metal material to have higher generalization, mostly adopt Fine Steel Casting iron: 45, 50 or steel alloy: 35SiMn, 40Cr, 20CrMnTi makes, thread rolling part 2 is through Quenching Treatment, increase hardness, groove 11 is rectangle, length is consistent with the length of screw plate body 1, the height of thread rolling part 2 is the height of screw plate body 1/1st three to 2/3rds, guarantee thread rolling part 2 can not shake or be out of shape in long-term work, affect processing effect, in order to reduce costs, the height of thread rolling part 2 is the height of screw plate body 1/1st three, the shape size of the shape size of groove 11 and thread rolling part 2 is suitable).
Described thread rolling part 2 is tabular, its bottom is inserted in groove 11 and the seamless cooperation of groove, its top is provided with tooth line 22, the bottom sidewall of described several thread rolling parts 2 all offers through hole 21, described screw plate body 1 sidewall runs through and is provided with the connecting hole 12 being connected with through hole 21, in described connecting hole 12, be inserted with the pin 13 that connects connecting hole 12 and through hole 21 for running through, tooth line 3 is for the screw thread on processing bolt, thread rolling part 2 and 1 seamless link of screw plate body, on the one hand, guarantee the hardness of screw plate body 1, on the other hand, prevent that thread rolling part 2 from rocking and then reducing the frequency of thread rolling part fracture in groove 11, pin 13 is inserted in connecting hole 12 and through hole 21, further connect thread rolling part 2 and screw plate body 1, increase the power that thread rolling part 2 can bear.Thread rolling part 2 adopts the principle of expanding with heat and contract with cold to complete interference fit with groove 11, thereby reaches the requirement of seamless link, and 2 of thread rolling parts quench for tooth line, reduce the cost quenching.When pin 13 is set to two, it is plugged in respectively the two ends that screw plate body 1 is relative, when the top of thread rolling part 2 and bottom are equipped with through hole, pin 13 can be plugged in top or the bottom of thread rolling part 2, also can all plug pin in top and the bottom of thread rolling part 2, now, the quantity of pin 13 is four.
The precision of the sidewall of described groove 11 and thread rolling part 2 sidewalls is all made as IT6 degree, through reality test proof, the above-mentioned optimal parameter that is set to this setting, both guaranteed the precision of assembling, seamless link, (precision of the sidewall of groove 11 and thread rolling part 2 sidewalls is all made as IT4～IT6 degree, more stable in order to assemble at utmost to save again manufacturing cost, increase service life and reduce costs, so preferentially select IT6).
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
