Abstract
The utility model discloses a hot heading die for a long-screw bolt. The hot heading die comprises a machine table, a main die, a punch and a crank-slider mechanism. The main die is fixed to the machine table, and a working face of the main die is provided with a horizontal cylindrical hole for containing a screw of the long-screw bolt. The punch is provided with a stepped hole matched with the head portion of the long-screw bolt in shape and installed on a slider of the crank-slider mechanism. The axial line of the stepped hole aligns with that of the cylindrical hole. The slider of the crank-slider mechanism can do straight reciprocating motion in the axial direction of the cylindrical hole. The hot heading die for the long-screw bolt can reduce labor intensity of operators and improve production efficiency, and is simple in structure.
Description
Technical field
The utility model relates to the mould applications in machining, is specifically related to a kind of hot upsetting mould for bolt of long stem.
Background technology
In the machining of the standard components such as screws bolts, be all generally to adopt cold-heading, equipment used is multistage cold former, and working (machining) efficiency is higher, and quality also easily guarantees.
But for compared with the bolt of stock (as length is greater than 200mm), the stroke of multistage cold former is inadequate, cannot produce, and carries out the hot upsetting of craft after can only heating, be specially manual workpiece main mould, the manual drift extruding workpiece that promotes put into.
The problem of manual hot upsetting is: because drift is mould steel material, weight ratio is heavier, and the motion of drift is to slide, and is not to roll, and manual to promote the strength that drift needs larger, and operator's labour intensity is large.In addition, because bolt Length Ratio is larger, therefore when main mould and drift parting, the distance of leaving is longer, and therefore the manual stroke promoting is also long, and efficiency is low.
Therefore, improve the hot upsetting mould for bolt of long stem, can alleviate operator's labour intensity, enhance productivity, and simple in structure, be this area technical issues that need to address.
Utility model content
The technical problems to be solved in the utility model: in the hot upsetting operation of bolt of long stem, operator's labour intensity is large, and production efficiency is low.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
For a hot upsetting mould for bolt of long stem, comprise board, main mould, drift and slider-crank mechanism; Described main mould is fixed on described board, its working face offer horizontal direction, for holding the cylindrical hole of screw rod of described bolt of long stem; Described drift offers the stepped hole mating with described bolt of long stem nose shape, is arranged on the slide block of described slider-crank mechanism the axis of described stepped hole and the axial alignment of described cylindrical hole; The slide block of described slider-crank mechanism can do straight reciprocating motion along described cylindrical hole axis direction.
Preferably, the cross section of described slide block is rectangle, is arranged on the base plate that is provided with rectangle chute, and described base plate is fixed on described board.
Preferably, crank one end of described slider-crank mechanism is arranged on described slide block, and one end is arranged on a disk that is provided with handle, can rotate.
Pass through technique scheme, the utility model promotes the matched moulds of drift and main mould by a slider-crank mechanism, wherein main mould maintains static, drift is arranged on the slide block of slider-crank mechanism, then by a rotation band movable slider with the disk of handle, do rectilinear motion, namely drift does the motion of matched moulds and parting.Its beneficial effect is to alleviate operator's labour intensity, enhances productivity, and simple in structure.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram (wherein board is not shown) of the disclosed hot upsetting mould for bolt of long stem of the utility model embodiment.
Numeral and the represented corresponding component title of letter in figure:
1. main mould 2. drift 3. slide block 4. crank 5. disk 6. base plate 7. bolt of long stems
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Principle of the present utility model is: the matched moulds that promotes drift and main mould by a slider-crank mechanism, wherein main mould maintains static, drift is arranged on the slide block of slider-crank mechanism, then by a rotation band movable slider with the disk of handle, do rectilinear motion, namely drift does the motion of matched moulds and parting.
Embodiment.
As shown in Figure 1, a kind of hot upsetting mould for bolt of long stem, comprises board, main mould 1, drift 2 and slider-crank mechanism; Main mould 1 is fixed on board, its working face offer horizontal direction, for holding the cylindrical hole of screw rod of bolt of long stem 7; Drift offers the stepped hole mating with bolt of long stem nose shape, is arranged on the slide block 3 of slider-crank mechanism the axis of stepped hole and the axial alignment of cylindrical hole; The slide block 3 of slider-crank mechanism can do straight reciprocating motion along cylindrical hole axis direction.
The straight reciprocating motion of the slide block 3 by slider-crank mechanism, has just completed the matched moulds motion of drift and main mould.
The cross section of slide block 3 is rectangle, is arranged on the base plate 6 that is provided with rectangle chute, and base plate is fixed on board.The processing of slide block 3 and base plate 6 is all fairly simple like this.
Crank 4 one end of slider-crank mechanism are arranged on described slide block 3, and one end is arranged on a disk 5 that is provided with handle, can rotate.Operator arrests handle with hand, and rotary disk 5 just can make slide block 3 do straight reciprocating motion.
In the above-described embodiments, the utility model promotes the matched moulds of drift and main mould by a slider-crank mechanism, wherein main mould maintains static, drift is arranged on the slide block of slider-crank mechanism, then by a rotation band movable slider with the disk of handle, do rectilinear motion, namely drift does the motion of matched moulds and parting.Its beneficial effect is to alleviate operator's labour intensity, enhances productivity, and simple in structure.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
