Description
Technical field
The utility model relates to a kind of cold-heading equipment, is specifically related to a kind of clamp structure of cold headers.
Background technology
Cold headers are that metal wire rod carries out cutting off and cold extrusion by one, make the equipment of metal wire rod cold-heading molding in upsetting molding jig, for processing various standard, non-standard securing member and component of rod category.Cold headers clamp structure workpiece clamp is stayed in the parts carrying out between each station of cold headers transmitting, because some workpiece need the cold-heading processing carrying out double end direction and vertical direction, and technology does not accomplish this point at present, can only carry out cold-heading processing in double end direction or vertical direction, and structure is quite complicated.Further, the clamp structure of prior art when opening and closing to open mouth very little, only by the cold-heading workpiece of minor diameter, can not the larger-diameter workpiece of upsetting system.
Summary of the invention
In view of the deficiency of background technology, it is simple that the purpose of this utility model aims to provide a kind of structure, can realize the cold headers clamp structure that workpiece double end direction and vertical direction cold-heading processing and clamp are opened greatly.
The utility model is implemented by following technical solution:
Cold headers clamp structure, it is characterized in that: comprise mounting seat, elevating lever, axle sleeve, clamp block, left and right tong arm, left and right clamp piece and rotary cylinder, axle sleeve is fixed in the vertical hole that mounting seat is provided with, elevating lever makes upper and lower lifting action at the endoporus of axle sleeve, the rod end up and down of elevating lever exposes to axle sleeve, the upper rod end of elevating lever is fixedly connected with lifting pushing ring, the lower rod end of elevating lever is connected with left and right tong arm, left and right tong arm is articulated and connected in clamp block, clamp block fixedly mounts in the bottom of axle sleeve, left pliers plate rotates the inner side being located at left chela, right pliers plate rotates the inner side being located at right chela, left and right chela fixedly mounts in the bottom of left and right tong arm, rotary cylinder is fixed on the outside of right chela, the rotating shaft of rotary cylinder is connected with right pliers plate.
Left and right tong arm is the design of symmetrically arranged L shape, the centre of left and right tong arm is articulated and connected at the left and right sides of clamp block by minor axis, the upper end of left and right tong arm is respectively equipped with elongated hole groove, and the pilot pin being fixed on rod end under elevating lever slides and is located in elongated hole groove, and the lower end of left and right tong arm is interlaced.
The cold headers clamp structure that the utility model provides, after workpiece is clamped by left and right clamp piece, workpiece can be driven to carry out the front and back upset of 180 degree and 90 degree by the spinning movement of rotary cylinder, so just can realize the cold-heading processing of workpiece double end direction and vertical direction, and structure is very simple; In addition, left and right clamp piece can carry out opening of big uncork under the drive of left and right tong arm, can better adapt to larger-diameter workpiece.Because the utility model can realize the double end direction of workpiece and the cold-heading processing of vertical direction and opening greatly of clamp, so greatly can expand the application space of cold headers.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in the figure, cold headers clamp structure of the present utility model, comprise mounting seat 4, elevating lever 2, axle sleeve 3, clamp block 5, left clamp arm 13, right clamp arm 7, left pliers plate 11, right pliers plate 10 and rotary cylinder 9, axle sleeve 3 is fixed in the vertical hole that mounting seat 4 is provided with, clamp block 5 fixedly mounts in the bottom of axle sleeve 3, elevating lever 2 makes upper and lower lifting action at the endoporus of axle sleeve 3, the rod end up and down of elevating lever 2 exposes to axle sleeve 3, the upper rod end of elevating lever 2 is fixedly connected with lifting pushing ring 1, the lower rod end of elevating lever 2 is connected with left and right tong arm, left and right tong arm is the design of symmetrically arranged L shape, the centre of left and right tong arm is articulated and connected at the left and right sides of clamp block 5 by minor axis 6, the upper end of left and right tong arm is respectively equipped with elongated hole groove 14, the pilot pin 15 being fixed on elevating lever 2 times rod ends slides and is located in elongated hole groove 14, the lower end of left and right tong arm is interlaced, left pliers plate 11 rotates the inner side being located at left chela 12, left chela 12 fixedly mounts in the bottom of right clamp arm 7, right pliers plate 10 rotates the inner side being located at right chela 8, right chela 8 fixedly mounts in the bottom of left clamp arm 13, rotary cylinder 9 is fixed on the outside of right chela 8, the rotating shaft of rotary cylinder 9 is connected with right pliers plate 10.
The utility model is performed such work: lifting pushing ring promotes elevating lever and moves downward, left and right clamp piece clamps workpiece, after workpiece is clamped by left and right clamp piece, workpiece is driven to carry out the front and back upset of 180 degree and 90 degree by the spinning movement of rotary cylinder, if workpiece carries out the front and back upset of 180 degree, so workpiece can realize the cold-heading processing in double end direction, if workpiece carries out the front and back upset of 90 degree, so workpiece can realize the cold-heading processing of vertical direction, when being elevated pushing ring promotion elevating lever and moving upward, left and right clamp piece can carry out opening of big uncork under the drive of left and right tong arm, better to adapt to larger-diameter workpiece.
