Abstract
The utility model relates to the technical field of cold-drawing machining of a metal tubular product and particularly relates to a head clamping device of a cold-drawing process. The head clamping device of the cold-drawing process comprises a clamp which is integrally smelted by a jaw and a jaw embedding plate, wherein the upper surface of the clamp is an inclined plane with a rectangular orthographic projection and the lower surface of the clamp is provided with a saw-tooth-shaped clamping groove; left and right end faces of the clamp are provided with clamping platforms which are parallel to the upper surface; the upper surface of the clamping platform is connected with the upper surface of the clamp to form the same inclined plane, so that the orthographic projection of the front end face of the clamp is in a T shape; the back end face of the clamp is provided with a mounting handle; and the mounting handle is provided with a through hole which is parallel to the bottom face and the back end face of the clamp. The head clamping device of the cold-drawing process disclosed by the utility model has the beneficial effects that the jaw and the jaw embedding plate are smelted into an integral structure so that the technical problem that the cold-drawing process is influenced by deformation of the jaw embedding plate caused by over-great stress is solved; and the structure is simple and reasonable and the head clamping device is convenient to machine and manufacture.
Description
Technical field
The utility model relates to metal pipe material cold-drawn processing technique field, relates in particular to a kind of cold-drawing technology head-clamp and holds device.
Background technology
The temperature of metal is divided during by drawing, and the drawing below recrystallization temperature is cold-drawn, and the drawing more than recrystallization temperature is hot drawing.Cold-drawn is to use the most general drawing mode during wire, line and pipe are produced.
For metal material, cold-drawn refers in order to reach certain shape and certain mechanical property, and the product of cold-drawn has in thermoforming: dimensional accuracy height and the good advantage of surface smoothness.
Existing Tube Drawing is to reprocess under cold state through the tubing after the hot-working, to produce the production method of precision, thin-walled, path or large footpath product.Cold-drawn need to clamp steel pipe with the cold-drawn clamping device and carry out drawing, general cold-drawn clamping device comprises jaw and the jaw panelling (such as Fig. 1, Fig. 2) that uses with the jaw assembly unit, because the extruding force that is subject to of jaw panelling is excessive in the course of the work, easily produce distortion, affect cold-drawn and directly spend, the A place of jaw panelling also can generating unit divide fracture when situation was serious.This has not only affected the cold-drawing technology quality, has also increased production cost.In addition, the bayonet socket place precision of the jaw panelling of jaw and clamping is high, and difficulty of processing is large, has brought inconvenience to the manufacturing.
The utility model content
The technical problems to be solved in the utility model is: in order to solve above-mentioned technical deficiency, the utility model provides a kind of cold-drawing technology head-clamp to hold device.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of cold-drawing technology head-clamp is held device, comprise the anchor clamps that are melt into integrative-structure by jaw and jaw panelling, the upper surface of described anchor clamps is the rectangular inclined-plane of orthographic projection, lower surface has the zigzag draw-in groove, the left and right sides both ends of the surface of anchor clamps have the Ka Tai parallel with upper surface, the upper surface of described Ka Tai and the upper surface of anchor clamps are linked to be same inclined-plane, so that the orthographic projection of anchor clamps front end face is "T"-shaped, the rear end face of described anchor clamps has installing handle, offers the through hole that is parallel to anchor clamps bottom surface and rear end face on the installing handle.
Further, particularly, described inclined-plane is 15～25 degree.
In order to reduce wearing and tearing, the intersection of the upper surface of described anchor clamps and anchor clamps left and right sides both ends of the surface is rounded corner
The beneficial effects of the utility model are, cold-drawing technology head-clamp of the present utility model is held device existing jaw and jaw panelling is melt into integrative-structure, solved the technical problem of jaw panelling because of stressed excessive generation influence of crust deformation cold-drawing technology, simple and reasonable, be convenient to processing and manufacturing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of jaw in the prior art.
Fig. 2 is the structural representation of jaw panelling in the prior art.
Fig. 3 is the structural representation that the utility model cold-drawing technology head-clamp is held the optimum embodiment of device.
Fig. 4 is the left view of Fig. 3.
Fig. 5 is the top view of Fig. 4.
Among the figure 1, anchor clamps, draw-in groove 1-1,1-2, Ka Tai, 2, installing handle, 2-1, through hole.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Shown in Fig. 3-5, the optimum embodiment that the utility model cold-drawing technology head-clamp is held device, comprise the anchor clamps 1 that are melt into integrative-structure by jaw and jaw panelling, the upper surface of anchor clamps 1 is the rectangular inclined-plane of orthographic projection, lower surface has zigzag draw-in groove 1-1, the left and right sides both ends of the surface of anchor clamps 1 have the card platform 1-2 parallel with upper surface, the upper surface of card platform 1-2 and the upper surface of anchor clamps 1 are linked to be same inclined-plane, so that the orthographic projection of anchor clamps 1 front end face is "T"-shaped, the rear end face of anchor clamps 1 has installing handle 2, offer the through hole 2-1 that is parallel to anchor clamps 1 bottom surface and rear end face on the installing handle 2, inclination angle of inclined plane is 15～25 degree, get 20 degree in the present embodiment, the intersection of the upper surface of anchor clamps 1 and anchor clamps 1 left and right sides both ends of the surface is rounded corner.
In the Cold Drawing Process, supported the use by a pair of anchor clamps 1, both lower surface left and right sides relative usages, the solid of clamping the steel pipe end carries out drawing, and the zigzag draw-in groove 1-1 of anchor clamps 1 lower surface and the screw thread on solid surface are complementary.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
