Abstract
The utility model relates to a middle concave driving mechanism for a moving cutter shaft of a spring coiling machine, which is composed of a power input shaft, an input gear, a collision block, a moving block of a power transfer device, a guide key, a spring, an upper guide plate, a moving cutter shaft, etc. By the action of the collision block to the moving block of a power transfer device, and thereby, the moving cutter shaft and a cutter fixed on the moving cutter shaft are pushed by the moving block of a power transfer device for doing the periodic axial feed movement, and thereby, a steel wire is cut. Because the driving of the collision block to the moving cutter shaft is carried out the transfer and the buffering action of the power transfer device, and thus, the collision force is small, the stress conditions of the components and the parts are improved, the cutting ability is increased, the application range of the steel wire diameter is enlarged, and the use reliability of the machine and the service lives of the components and the parts are increased.
Description
The utility model relates to middle concave spring spring coiling machine and is used for the steel wire power drive mechanism of the moving slitter shaft of cut-out automatically.
Moving cutting knife on the moving slitter shaft of middle concave spring spring coiling machine is used for cutting off automatically steel wire, must do periodic axial feed motion so moving slitter shaft drives moving cutting knife.The spring coiling machine of home and abroad production at present, the feed power of moving slitter shaft is to be realized by the projection that power shaft, input gear driven collision block directly impinge upon on the moving slitter shaft tail end, like this, make slitter shaft bear very big radial impact load, make the slitter shaft distortion easily, even fracture, cause machine halt trouble, influenced the normal use of complete machine; Simultaneously, power input shaft and input gear also will bear very big axial impact force and impact moment, have influenced the service life of complete machine, owing to there is above-mentioned defective, have also limited the scope of application of steel wire diameter.
The purpose of this utility model is to overcome the defective of prior art and a kind of radial impact load that alleviates moving slitter shaft and power input shaft, the axial impact force of input gear, the motor-driven slitter shaft transmission mechanism of middle concave spring wind spring of impact moment is provided, so that improve the dependability and the life-span of machine and enlarge the scope of application of steel wire diameter.
The purpose of this utility model is achieved in that and comprises power input shaft and the input gear that is in transmission connection, collision block transmission on the input gear is bearing in the tank ends bearing, do periodic axial feed motion by the moving slitter shaft of spring reset, its improvements are to be provided with power transmission between described collision block and the moving slitter shaft, this device comprises and moves the contacted motion block in slitter shaft inclined-plane, motion block is arranged between casing bearing-surface and the upper guide plate, lead key as the motion block slide-and-guide is fastened on the casing bearing-surface with upper guide plate, and the spring that motion block is resetted is located at the motion block rear end.
The utility model is owing to be provided with power transmission between collision block and moving slitter shaft, make impact at first act on the power transmission, and then the transmission by power transmission and buffering effect promote moving slitter shaft, realize the automatic cut-out of steel wire thus, thereby overcome the defective of prior art, improved the cut-out ability, enlarged the scope of application of steel wire diameter, because the force-bearing situation of power input shaft, input gear and moving slitter shaft improves, improved the service life of machine dependability and parts simultaneously.
Description of drawings.
Fig. 1 is a structure cross-sectional schematic of the present utility model.
Fig. 2 is that the A of Fig. 1 is to revolved view.
Below in conjunction with above-mentioned accompanying drawing embodiment of the present utility model is described in detail again.
Shown in Fig. 1-2, the motor-driven slitter shaft transmission mechanism of middle concave spring wind spring comprises power input shaft (9) and the input gear (8) that is in transmission connection, the collision block of column construction (7) is connected on the input gear by bearing pin, promote moving slitter shaft (5) by the motive force of cylindricality collision block bump through the transmission of power transmission and buffering effect thus do periodic axial feed motion and cut off steel wire automatically.
Power transmission comprises the motion block (6) that the end that is subjected to collision block (7) bump takes the form of inclined plane, and the skew back face of motion block contacts with the angled end-face of moving slitter shaft (5).Motion block is arranged between casing (1) bearing-surface and the upper guide plate (2), upper guide plate also plays dustproof effect simultaneously, be located in the motion block and with last Leader as the lead key (4) of motion block slide-and-guide and be fastened on the casing bearing-surface, the spring (3) that motion block is resetted is located at the motion block rear end.Moving slitter shaft is bearing in the oiliness bearing of tank ends, and axle is provided with the spring (11) that resets.
In order to regulate the initial position between motion block (6) and the moving slitter shaft (5), be provided with the adjustment screw (10) that changes the motion block position, an end of adjustment screw is connected on the casing, and the spring housing that motion block is resetted is contained on the adjustment screw of motion block rear end.
Dynamic structure of the present utility model be when spring coiling machine shaping, the expansion end of job after, the inclined-plane of cylindricality collision block (7) collision motion block (6) end under power input shaft (9) and input gear (8) revolution drive, make motion block along lead key (4) slip (Fig. 1) left on casing (1) bearing-surface, and drive the cutting knife of fixing on it (12) by the moving slitter shaft (5) that motion block skew back face promotes contact with it and move right (Fig. 2), thereby cut off steel wire automatically.Afterwards, motion block and moving slitter shaft reset under spring (3) and (11) effect respectively, enter next circulation position automatically, for periodic axial feed motion is prepared.
Claims (3)
1, the motor-driven slitter shaft transmission mechanism of a kind of middle concave spring wind spring, comprise the power input shaft (9) and the input gear (8) that are in transmission connection, collision block (7) transmission on the input gear is bearing in casing (1) bearings at both ends, the moving slitter shaft (5) that resets by spring (11), do periodic axial feed motion, it is characterized in that: be provided with power transmission between described collision block (7) and the moving slitter shaft (5), this device comprises and moves the contacted motion block in slitter shaft inclined-plane (6), motion block is arranged between casing (1) bearing-surface and the upper guide plate (2), lead key (4) as the motion block slide-and-guide is fastened on the casing bearing-surface with upper guide plate, and the spring (3) that motion block is resetted is located at the motion block rear end.
