Abstract
The utility model discloses a cold drawing machine trolley connector, which comprises a motor (1), a speed reducer (8), a friction plate (7), a first belt pulley (2), a second belt pulley (4), a spring (6) and a spring compression block (5). The first belt pulley (2) is connected with the motor (1), the second belt pulley (4) is connected with the first belt pulley (2) via a belt (3), the second belt pulley (4) is connected with the friction plate (7), a shaft (11) is arranged on the back of the friction plate (7), the spring (6) is sleeved on the shaft (11), one end of the spring (6) is abutted to the back of the friction plate (7) while the other end is abutted to the spring compression block (5), and the second belt pulley (4) is connected with the speed reducer (8). Compared with the prior art, the cold drawing machine trolley connector adopting the structure has the advantages of lower cost and higher production efficiency.
Description
Technical field:
The utility model relates to a kind of steel pipe manufacture field, specifically is a kind of dolly connector that is used for drawbench.
Background technology:
So-called cold-drawn processing is meant adopts withdrawing pattern that the direct cold-drawn of large diameter tubing is the tubing than minor diameter, and drawbench is in order to tubing is carried out a kind of plant equipment that tube reducing subtracts wall or subtracts wall hole enlargement processing.Drawbench generally comprises the drawing dolly of withdrawing pattern, track-movable and the dolly connector that is connected with the drawing dolly, and the dolly connector generally is to provide tractive force by motor and transmission mechanism to dolly, hauls dolly and moves along track.Existing dolly connector generally comprises motor, decelerator, belt pulley, be connected by sprocket wheel between motor and the decelerator, it adopts belt pulley and belt to provide power to dolly, because the required tractive force of dolly is very big, thus belt skid easily, thereby wearing and tearing easily, and very trouble is changed in the wearing and tearing back, seriously influence production efficiency, and owing to need constantly change belt, thereby also cause the waste of belt to cause cost to increase simultaneously.
The utility model content:
The technical problems to be solved in the utility model is, overcomes existing technological deficiency, provides a kind of cost lower, the dolly connector that is used for drawbench that production efficiency is higher.
Technical solution of the present utility model is, a kind of dolly connector that is used for drawbench is provided, it comprises motor, decelerator, it also comprises frictional disk, first belt wheel, second belt wheel, spring, spring compression piece, described first belt wheel is connected with motor, described second belt wheel is connected with first belt wheel by belt, and described second belt wheel is connected with frictional disk, and described frictional disk back is provided with wheel shaft, described spring housing is on axle, one end and the frictional disk back of spring offset, and the other end and spring compression piece offset, and described second belt wheel is connected with decelerator.
After adopting said structure, the utlity model has following advantage:
After adopting above structure, the utility model compared with prior art, frictional disk, spring and spring compression piece have been formed a strigil, the workman can be by the frictional resistance between the regulating spring compact heap adjusting frictional disk and second belt wheel, when the required pulling force of dolly was big, the power of coming by the decelerator transmission was during greater than the frictional resistance of strigil, and second belt wheel just can skid, thereby the belt pulley that directly is connected with dolly just can not skidded, and it is less to wear and tear.And the belt that is connected with first belt wheel and second belt wheel is connected with dolly by decelerator owing to be positioned at motor side, directly is not connected with dolly, so needn't bear bigger pulling force, and stroke is shorter, so can adopt the belt of lower cost, and it is also comparatively convenient to change, and production efficiency is higher.
As improvement, described it also comprise sprocket wheel, described sprocket wheel is connected with decelerator by sprocket shaft, sprocket wheel is connected with dolly by chain, uses sprocket wheel to replace belt pulley, thereby can reduce the use belt, has reduced the loss of belt more.
Description of drawings:
Accompanying drawing 1 is the structural representation of dolly connector of the drawbench of prior art;
Accompanying drawing 2 is structural representations of the dolly connector of the utility model drawbench;
As shown in the figure, in the prior art: 1a, motor, 2a, sprocket wheel, 3a, decelerator, 4a, belt pulley;
In the utility model: 1, motor, 2, first belt wheel, 3, belt, 4, second belt wheel, 5, the spring compression piece, 6, spring, 7, frictional disk, 8, decelerator, 9, sprocket shaft, 10, sprocket wheel.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Be the structural representation of dolly connector of the drawbench of prior art as shown in Figure 1, as shown in the figure: it comprises motor 1a, decelerator 3a, belt pulley 4a, described motor 1a directly is connected by sprocket wheel 2a with decelerator 3a, described decelerator 3a is connected with belt pulley 4a, and motor 1a drives belt pulley 4a and is connected with dolly by the driving belt on the belt pulley 4a, thereby drives moving of car.
As improvement, described it also comprise sprocket wheel 10, described sprocket wheel 10 is connected with decelerator 8 by sprocket shaft 9.Sprocket wheel is connected with dolly by chain, uses sprocket wheel to replace belt pulley, thereby can reduce the use belt, has reduced the loss of belt more.
