The cylindrical steel bar upsetting die of theutility model can reduces die crack during using, promotes service life of the mould and reduces machining difficulty and cost of the die.
Description
Technical field
The utility model relates to the steel bar thick mould, and relating in particular to a kind of outer surface is columniform steel bar thick mould.
Background technology
In building construction process, usually there is a large amount of reinforcing bars to connect.Traditional colligation connected mode is seldom used.Commonly used now is welding and straight thread mechanical connection manner.Welding manner is difficult to guarantee quality of connection owing to be subjected to influence of various factors such as welder's level, Electroplating welding materials, welding procedure environment and weather.So the straight thread mechanical connection manner is used widely in recent years.
Steel bar thick straight thread mechanical connection is a kind of main method during present reinforcing steel bar machinery connects, and also is a kind of during the equal strength reinforcing steel bar machinery connects.The equal strength reinforcing steel bar machinery connects the mechanical connection method of the intensity of joint area more than or equal to the reinforced steel bar strength that is used for connection that be meant.The reinforced bar straight thread mechanical connection manner is to cut into two straight thread silk heads again behind two reinforcing bar respective end portions process cold-heading jumping-up technology jumping-ups, then a kind of connecting method for reinforcing bars that two reinforced bar straight thread silk heads is connected with the branch sleeve that has the straight thread internal thread (screw thread of silk head can mate with the screw thread in the branch sleeve).
Fig. 1 looks schematic diagram for the master of one of two clamps in the existing reinforcing bar pier roughcast tool; Fig. 2 looks schematic diagram for the left side of the clamp shown in Fig. 1; Fig. 3 looks schematic diagram for the master of one of two formation of lots pieces in the existing reinforcing bar pier roughcast tool; Fig. 4 looks schematic diagram for the left side of the forming blocks shown in Fig. 3; Fig. 5 is the thick preceding user mode schematic diagram of the pier of existing reinforcing bar pier roughcast tool; Fig. 6 is the user mode schematic diagram of the pier of existing reinforcing bar pier roughcast tool after thick.Extremely shown in Figure 6 as Fig. 1, the reinforcing bar pier roughcast tool that uses comprises the clamp 1 and the forming blocks 4 of each dimidiation at present, described clamp 1 has the cavity 3 that is used to clamp reinforcing bar 8, and described forming blocks 4 has the cavity 5 that is used for the reinforcing bar moulding, and the outer surface of described clamp 1 and forming blocks 4 is square.Also be provided with locating hole 2 on the clamp 1, also be provided with locating hole 6 on the forming blocks 4.With set screw clamp 1 and forming blocks 4 are fixed on in two the anchor clamps (not shown) during use, reinforcing bar 8 is placed between the cavity 3 of two clamps 1, make its end expose the end face suitable length of forming blocks 4, close up anchor clamps then, compress axially expose end reinforced with the jumping-up bar heart 7, reinforcing bar produces plastic deformation under pressure, is full of the cavity of clamp 1 and forming blocks 4, reaches the thick purpose of pier.The clamp of the mould that also has and forming blocks are one.
The inventor is in realizing process of the present utility model, find that existing square reinforcing bar pier roughcast tool has following problem at least: the cavity cross section of existing reinforcing bar pier roughcast tool is shaped as circle, the appearance cross sectional shape is a rectangle, in the Mould Machining process, very easily produce the phenomenon of unbalanced stress, add that it is in uneven thickness, the stressed of each position of mould varies in size, thereby makes mould easy cataclastic failure in use, and service life is very short.Also time-consuming in the Mould Machining in addition, effort, processing cost height, the difficult axiality that guarantees cavity and outer surface.
The utility model content
The purpose of this utility model provides a kind of cylindrical reinforcing bar pier roughcast tool, and it is more even that its internal stress in manufacture process is distributed, during use stressed also relatively evenly.
In order to solve the problems of the technologies described above, the utility model provides a kind of cylindrical reinforcing bar heading die, the clamp and the forming blocks that comprise each dimidiation, described clamp has the cavity that is used to clamp reinforcing bar, described forming blocks has the cavity that is used for the reinforcing bar moulding, and the outer surface of described clamp and forming blocks is cylindrical.
As preferably, the columniform equal diameters of the outer surface of described clamp and forming blocks.
As preferably, the outer surface of described clamp and forming blocks is provided with location concave station or boss.
The cylindrical reinforcing bar heading die that the utility model provides has following beneficial effect at least: reduce the cracked phenomenon in the mould use, the service life of improving mould; Reduce the difficulty of processing and the cost of mould.

The specific embodiment
Describe embodiment of the present utility model with reference to the accompanying drawings in detail.
Accompanying drawing shows exemplary embodiment of the present utility model.Yet exemplary embodiment can be presented as different forms, and should not think the embodiment that it is confined to illustrate in the accompanying drawing.Exactly, it is in order to make the disclosure more thorough to one skilled in the art and complete that these embodiments are provided, and expresses scope of the present utility model fully.
Therefore, example in this specification and the structure shown in the accompanying drawing are a kind of preferred exemplary of the present utility model, do not represent all technological thoughts of the present utility model.The utility model can have various equivalents and modification when application.
Fig. 7 to Figure 11 is the clamp of cylindrical reinforcing bar pier roughcast tool of an embodiment of the present utility model and the schematic diagram of forming blocks.
Extremely shown in Figure 11 as Fig. 7, the cylindrical reinforcing bar heading die of present embodiment comprises the clamp 9 and the forming blocks 10 of each dimidiation, described clamp 9 has the cavity 11 that is used to clamp reinforcing bar, described forming blocks 10 has the cavity 12 that is used for the reinforcing bar moulding, and the outer surface 15,16 of described clamp 9 and forming blocks 10 is cylindrical.The columniform equal diameters of the outer surface 15,16 of described clamp 9 and forming blocks 10.The outer surface 15,16 of described clamp 9 and forming blocks 10 is provided with location concave station 13,14.Certainly, the location concave station also can replace with boss, and clamp 9 also can be made of one with forming blocks 10.By with mould (clamp 9, shaping piece 10) outer shape by original square change into cylindrical, make its internal stress in manufacture process distribute more even, during use stressed also relatively evenly, thereby reduce the cracked phenomenon of mould, the service life of improving mould.
