Abstract
The utility model relates to the technical field of cold-drawing machines, in particular to a drawing trolley of a profiled bar cold-drawing machine, which comprises wheels, a frame and a clamping mechanism. The clamping mechanism is arranged on the rear of the frame. The drawing trolley is characterized in that a hook fastened with a chain of the cold-drawing machine is hinged at the front end of the frame, a tension spring is disposed between the hook and the frame, the hook is unhooked by the aid of the tension spring, the clamping mechanism consists of a handle, two wedge blocks and slide grooves for holding the wedge blocks, and the two wedge blocks are in transmission connection with the handle by gears. The drawing trolley in the technical scheme is high in clamping force and low in cost, cannot be damaged easily and can be automatically combined with and separated from the chain.
Description
Technical field
The utility model relates to the drawbench technical field, especially a kind of profile shapes drawbench drawn-car.
Background technology
Drawbench is a kind of machinery that the metal pole stock is carried out tube reducing or distortion; Usually the reciprocating motion that is employed in the drawing dolly of same horizontal plane setting realizes the stretching of pole stock and sends to, realizes the clamping to pole stock in the reciprocating folding of controlling clamp on the drawing dolly simultaneously.Cold-drawn adds man-hour, at first mould is passed in finished pole stock end, utilizes the clamping device of drawn-car front end to clamp the pole stock end then, thereby through the traction drawn-car blank is extracted through mould, obtains required finished section bar.
Clamp mechanism on the existing drawn-car is divided into mechanical type and fluid pressure type, and what the clamp mechanism of the drawn-car of mechanical type drawbench adopted is the lever-type clamp principle, and clamping force is little, and the back mechanical type clamp sensitivity that works long hours descends, and damages easily; The hydraulic pressure drawn-car clamping force of hydraulic pressure cold drawing machine is big, and noise is little during work, but reliability is not high, cost is higher.The traction of drawing dolly generally adopts chain to apply active force in addition, existing dolly and chain fixing and unclamp common artificial intervention that need, and automaticity is not high.
The utility model content
The technical problem that the utility model will solve provide a kind of clamping force greatly, not fragile, cost is low and the profile shapes drawbench drawn-car that can combine with chain automatically and unclamp.
In order to solve the problems of the technologies described above; The utility model provides a kind of profile shapes drawbench drawn-car; Comprise wheel, vehicle frame and the clamp mechanism that is arranged on the vehicle frame rear portion, the front end of said vehicle frame is hinged with the hook that is interlocked with the drawbench chain, is provided with the extension spring that makes said hook be in the unhook normality between hook and vehicle frame; Described clamp mechanism includes handle, two wedges and settles the chute of wedge, and two wedges are connected through gear drive with handle.
After a cold-drawn operation was accomplished, the cold-drawn dolly can proceed to the sprocket wheel place of drawbench, and the tooth on the sprocket wheel can be extruded the hook of drawn-car from chain; Under the effect of extension spring, hook keeps the unhook normality, and drawn-car pushes back to the start position of stretching rapidly along the guide rail of drawbench; And stopped by being stopped, can overcome the extension spring active force at the action of inertia lower draw-bar and be anchored on the chain once more, thereby drawn-car is combined with chain; The workman will treat that the pole stock of cold-drawn passes die hole this moment, and the end of pole stock is inserted between two voussoirs, then turning handle; Handle clamps pole stock through gear driven two wedges, and drawn-car spurs pole stock and passes die hole under the effect of chain then, in this process; Pole stock spurs two wedges and in chute, pushes, and has further clamped pole stock.
Adopt the profile shapes drawbench drawn-car of technique scheme to have following advantage: 1; Owing to adopted two wedges to cooperate the design that clamps with chute; Pole stock spurs two wedges and constantly clamps pole stock along chute; Make clamping force bigger and not fragile, since simple in structure, so the cost input is also lower; 2; Because the front end of vehicle frame is hinged with the hook that is interlocked with the drawbench chain, be provided with the extension spring that makes said hook be in the unhook normality between hook and vehicle frame, when drawn-car process sprocket wheel, can make hook break away from chain automatically; And when drawn-car pushes back original position and stops suddenly; Hook can overcome the extension spring resistance and cooperate with chain again under the inertial collision active force, the process of whole unhook and hook need not the workman and gets involved, and automaticity is higher.
As preferred version, in order further to improve the efficient of drawbench, described clamp mechanism is provided with two groups, can connect two pole stocks so simultaneously and carry out cold-drawn.
As preferred version, in order to reduce the weight of hook, reduce to link up with impact to drawn-car and chain, described hook is provided with the hole of loss of weight.
Description of drawings
Fig. 1 is the sectional structure sketch map of the utility model embodiment profile shapes drawbench drawn-car.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model technical scheme is further specified:
As shown in Figure 1; The utility model provides a kind of profile shapes drawbench drawn-car, comprises wheel 1, vehicle frame 2 and the clamp mechanism that is arranged on the vehicle frame rear portion, and the front end of vehicle frame 2 is hinged with the hook 3 that is interlocked with the drawbench chain; Hook 3 is provided with the hole 4 of loss of weight; Hook 3 and 2 of vehicle frames are provided with the extension spring 5 that makes said hook be in the unhook normality, and clamp mechanism includes handle 6, two wedges 7 and settles the chute of wedge, and two wedges 7 are connected through gear drive 8 with handle 6.Clamp mechanism is provided with two groups (only having drawn in the profile one group).
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection domain of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
