Abstract
The utility model relates to a clamping head for drawing reinforced bars. In the past the special-purpose reinforced bar clamping head is not arranged. The utility model comprises a hole 10 in which a reinforced bar is inserted and a clamping conical surface 11 are arranged in a shell body 1. The shape of the clamping conical surface 11 is consistent with the shape of a curved surface 12 on a clamping head 2. The clamping head 2 is divided into sheets. A dental plate 3 is totally installed on each clamping head 2. A clamping tooth 4 is arranged on the dental plate 3. A spring 6 is also installed in the shell body 1, and a spring control hole is arranged in the shell body 1. The utility model can be used as a circular disk straightening clamping apparatus in the building industry. When the utility model is used, the reinforced bar is not required to cut off. Consequently the utility model is suitable for pulling into the reinforced bar for disks. The utility model can be also used for pulling out the old reinforced bar whose one head is exposed out of the ground in the residual ground. Because the reinforced bar is not required to bend, the utility model can be directly pulled out. The utility model has the advantage of low cost.
Description
The utility model relates to a kind of processing reinforcing bar special mould clamp, the dop of particularly a kind of drawing reinforcing bar special use.
In the prior art,, need reinforcing bar be bended, fix reinforcing bar with curved, with the balance pulling force in the termination of reinforcing bar if think cold-drawn, hard drawn wire reinforcement.Both wasted steel, also restricted to reinforcing bar length, particularly remain in old reinforcing bar that bassets in the soil, job site, the cost that the difficulty of bending is pulled out is very big, never good jig.
The purpose of this utility model is to provide a kind of Clamp for drawing steel bar, use this instrument can cold-drawn under the curved previous status of reinforcing bar, hard drawn wire reinforcement.
The purpose of this utility model is achieved in that to have the hole and the chucking conical surface that reinforcing bar inserts in housing, the described chucking conical surface is consistent with the curve form on the dop, curved surface on the described dop is contained among the chucking conical surface, described dop is a burst, on each sheet dop dental lamina is housed all, have the card tooth on the described dental lamina, spring also is housed in the described housing and has the spring control hole.
The burst form of the dop of this product can be to be divided into three.
The card tooth of this product is uniform on described dental lamina, and sideline, thread form both sides all is acute angle with the reinforcing bar direction of insertion.
The tapering of the conical surface in this product is 45～80.
Advantage of the present utility model is:
1. easy to use, block automatically when withdrawing from backward after reinforcing bar inserts in the hole, block tighter and tighter by the conical surface.
2. down but can be stuck in steel bar end, also may be stuck in any position in the reinforcing bar, be best suited for the stretching jig of dish circle of doing builing industry, need not cut off, how long draw can, very practical.
3. when being used for pulling out the old reinforcing bar that remains in that one in soil, job site bassets, the reinforcing bar that bends after need not digging pit can directly pull out, and the cost of pulling out reduces a lot.
4. cost is low, is easy to promote, and is easy to carry.
Accompanying drawing 1 is a structural representation of the present utility model.Accompanying drawing 2 is A-A sectional drawings of accompanying drawing 1
Accompanying drawing 3 is B-B sectional drawings of accompanying drawing 1
Be further described below in conjunction with accompanying drawing:
Embodiment 1: a kind of Clamp for drawing steel bar, in housing 1, have the hole 10 and the chucking conical surface 11 that reinforcing bar inserts, the described chucking conical surface 11 is consistent with conical camber 12 shapes on the dop, curved surface 12 on the described dop 2 is included among the chucking conical surface 11, described dop 2 can be a burst, on each sheet dop 2 dental lamina 3 is housed all, every with can gapped 8, dental lamina 3 can be friction tight being installed in the dop 2, also can be fixed on the dop 2, have card tooth 4 in groups on the dental lamina 2 with securing member 5.
Embodiment 2: embodiment 1 described Clamp for drawing steel bar, the burst form of its dop 2 can be to be divided into three to have made it three groups of chucking stress points, and what diameter was big also can be divided into four or six, to disperse clamping force, strengthens the chucking effect.In every, card tooth 4 with hoop or axially also can establish groove 15, with increase the tooth number make it stressed evenly.Spring 6 also is housed in the described housing 1 and has spring control hole 9, when withdrawing from reinforcing bar, by control hole 9 spring 6 is dialled to compression direction, then dop 2 is drawn back, and reinforcing bar is loosened radially becoming big in the gap between the card tooth 4, allows it axially movable.When using compression spring scheme, spring 6 can be enclosed within on the dop 2, the dogging shoulder 14 of dop 2, the bonnet 7 that housing 1 is lived on a crown are lived in one crown, bonnet 7 can be fixedly connected by screw thread or holding screw and housing 1, the position of spring can be limited by screw 13, and bonnet 7 also can be made one with housing 1.
Embodiment 3: embodiment 1 or 2 described Clamp for drawing steel bar, and its card tooth is uniform on described dental lamina, and sideline, thread form both sides 16 all is acute angle with reinforcing bar direction of insertion c, and it is reliable strong to make it chucking.
Embodiment 4: embodiment 1 or 2 or 3 described Clamp for drawing steel bar, the tapering of its conical surface 11 and the conical surface 12 is 45～80 °, can be according to conical surface angle adjustment chucking component such as 60 °.
Claims (4)
1. Clamp for drawing steel bar, it is characterized in that: in housing, have the hole and the chucking conical surface that reinforcing bar inserts, the described chucking conical surface is consistent with the curve form on the dop, curved surface on the described dop is contained among the chucking conical surface, described dop is a burst, on each sheet dop dental lamina is housed all, has the card tooth on the described dental lamina, spring also is housed in the described housing and has the spring control hole.
2. Clamp for drawing steel bar according to claim 1, the burst form of described dop are to be divided into three.
