Description
Technical Field
The utility model relates to a screw plate especially relates to a screw plate that is used for carrying out thread machining to high accuracy bicycle spoke.
Background
At present, screw forming of parts such as bolts, screws, and studs is often performed by extrusion using a thread rolling die. For bicycle spokes, a screw plate for bicycles is generally adopted as disclosed in Chinese patent CN201420795984.2, and the bicycle spokes are made of hard alloy materials due to high precision; as the thread rolling plate is inevitably worn in the extrusion process, the use cost is greatly increased, and the manufacture cost of the product is not reduced.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned not enough, provide a high fine bicycle is screw plate for spoke that is favorable to reducing use cost.
The purpose of the utility model is realized like this:
the utility model provides a high fine bicycle is screw plate for spoke, includes plate body and connecting block, the plate body is the integral type U-shaped structure that comprises two parallel arrangement's riser and the diaphragm of connecting between two risers, and the surface of diaphragm be the thread rolling face, the vertical slot that is provided with on the inner wall of two risers, the vertical cutting that is provided with in both sides of connecting block, above-mentioned connecting block are inserted in the U-shaped opening of arranging the plate body in through inserting the cutting of arranging in the slot.
The utility model relates to a high accurate thin screw plate for bicycle spoke is provided with at least one screw one on the at least riser of plate body, the side of connecting block is provided with the screw two that corresponds with screw one, and fastening bolt arranges in screw two after passing screw one soon.
The utility model relates to a high-fineness screw plate for bicycle spoke, it has heat conduction silica gel layer to fill between the contact surface of the diaphragm of connecting block and plate body.
The utility model relates to a high accurate thin bicycle is screw plate for spoke, the side of the riser of plate body is provided with radiating groove one, the side of connecting block is provided with radiating groove two, and radiating groove one link up with radiating groove two-phase.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a split type structure after, can be convenient only change the plate body that has the face of rubbing with the hands, and need not to change the connecting block, reduced use cost. Meanwhile, through the design of the heat-conducting silica gel layer and the design of the heat dissipation groove, the heat dissipation performance is accelerated, and the processing precision is guaranteed.
Drawings
Fig. 1 is the utility model relates to an assembly effect schematic diagram of high fine bicycle is screw plate for spoke.
Fig. 2 is a schematic view of another embodiment of the high-precision thread rolling die for bicycle spokes of the present invention.
Wherein:
the plate body 1 and the connecting block 2;
the heat dissipation structure comprises a slot 1.1, a screw hole I1.2 and a heat dissipation groove I1.3;
the cutting 2.1, screw two 2.2, radiating groove two 2.3.
Detailed Description
Referring to fig. 1, the utility model relates to a high-precision thread rolling plate for bicycle spokes, which comprises a plate body 1 and a connecting block 2, wherein the plate body 1 is an integral U-shaped structure formed by two parallel vertical plates and a transverse plate connected between the two vertical plates, the outer surface of the transverse plate is a thread rolling surface, an inserting groove 1.1 is vertically arranged on the inner walls of the two vertical plates, inserting strips 2.1 are vertically arranged on two sides of the connecting block 2, and the connecting block 2 is inserted into a U-shaped opening of the plate body 1 through the inserting strips 2.1 inserted into the inserting grooves 1.1;
furthermore, at least one vertical plate of the plate body 1 is provided with at least one screw hole I1.2, the side surface of the connecting block 2 is provided with a screw hole II 2.2 corresponding to the screw hole I1.2, and a fastening bolt penetrates through the screw hole I1.2 and then is screwed in the screw hole II 2.2, so that the effect of strengthening connection is further achieved;
furthermore, a heat-conducting silica gel layer is filled between the connecting block 2 and the contact surface of the transverse plate of the plate body 1, so that heat during working can be uniformly dissipated outwards;
referring to fig. 2, a first heat dissipation groove 1.3 is formed in the side surface of the vertical plate of the plate body 1, a second heat dissipation groove 2.3 is formed in the side surface of the connecting block 2, and the first heat dissipation groove 1.3 is communicated with the second heat dissipation groove 2.3; thereby increasing the heat dissipation area and improving the heat dissipation performance when in work;
in addition: it should be noted that the above-mentioned embodiment is only a preferred embodiment of the present patent, and any modification or improvement made by those skilled in the art based on the above-mentioned conception is within the protection scope of the present patent.
