Detailed Description
The present invention will be further described with reference to the following drawings and examples, and embodiments of the present invention include, but are not limited to, the following examples.
As shown in fig. 1, a novel steel bar cold-drawing machine comprises a frame 1, and a guide pulley mechanism, a feeding mechanism, a cold-drawing mechanism and a steel bar withdrawing mechanism which are sequentially arranged.
The guide pulley mechanism comprises a plurality of groups of guide pulleys, and each group of guide pulleys comprises two guide pulleys which are arranged oppositely. The guide pulley is rotatably arranged on the frame 1 through a rotating shaft. Specifically, two guide pulleys of the same group are respectively arranged on two supports through a rotating shaft, one ends of the two supports are connected with the guide pulleys through the rotating shaft, and the other ends of the two supports are connected with the sliding sleeve 4. Two sliding sleeve 4 sets up on optical axis 3, and optical axis 3 sets up in frame 1, sets up spring 5 between the one end of two sliding sleeve 4 dorsad and the frame 1. Based on this structure, the clearance that supplies the reinforcing bar to pass between two pulleys of direction assembly pulley can be adjusted according to the size of reinforcing bar by oneself.
Feeding mechanism includes two feed trays 6, and two feed trays 6 are connected with the motor output respectively, and the motor output is connected with the motor installation piece, and the motor installation piece passes through the support setting on sliding sleeve 4, and sliding sleeve 4 sets up on removing axle 8, can rotate on removing axle 8, and two faces at least of sliding sleeve 4 are equipped with bolt 9 hole, and the downthehole bolt 9 that is equipped with of bolt 9 fastens the position of sliding sleeve 4 on removing axle 8 through bolt 9. The purpose of the feeding mechanism is the same as that of the feeding mechanism, the feeding mechanism can be adjusted according to the size of the steel bar, and meanwhile, after the distance adjustment is completed by the feeding disc 6, the feeding disc can be fastened by screwing the bolts 9 to stabilize the distance. Furthermore, a feeding groove is formed in the ring surface of the feeding plate 6, and when feeding is conducted, the reinforcing steel bars are located in the feeding groove, so that the stress is more uniform.
The cold drawing mechanism comprises a cold drawing table top 10, a plurality of lifting devices 12 and a cold drawing die 11. The cold drawing table top 10 is arranged on the frame 1, and a plurality of lifting devices 12 are sequentially arranged on the frame 1 above the cold drawing table top 10. The lifting device 12 may be a pneumatic cylinder or an electric push rod. The lifting end of the lifting device 12 is provided with a mounting block, and the cold-drawing die 11 is detachably arranged on the mounting block through a bolt 9. Further, the frame 1 is further provided with a guide cylinder for a lifting rod of the lifting device 12 to pass through.
In particular, the feed tray 6 can also be located on the cold drawing bench. When the cold drawing die is used, when cold drawing is needed only once, the cold drawing die 11 with the corresponding specification is placed on the table top through the lifting device 12. If multiple cold drawing is needed, a plurality of cold drawing dies 11 with corresponding specifications are put down to the table top through a plurality of lifting devices 12.
Furthermore, the cold-drawing die hole of the cold-drawing die 11 has certain requirements on the setting position. In this embodiment, since the cold drawing is to be performed, in the cold drawing process, if multiple times of cold drawing are required, the cold drawing holes of the plurality of cold drawing dies 11 should be located on the same axis. The cold drawing holes of the cold drawing dies 11 with different specifications are different in size. Therefore, the mold holes of the cold-drawing mold 11 do not need to be arranged along the axis, and can be eccentrically arranged, so that when the cold-drawing molds 11 of different specifications are placed on the cold-drawing table top 10, a plurality of cold-drawing mold holes are positioned on the same axis, and cold drawing is facilitated.
It is important to emphasize that the feed table 6 and the cold-drawing die 11 do not need to be coaxial, so that the rolling head can be introduced into the first cold-drawing die 11 by rolling the head while the bar passes through the first cold-drawing die.
At the same time, it is emphasized that several lifting devices 12 are installed at a short distance from the cold-drawing die 11, even up to a distance of not more than 3 cm. The closer distance of the cold-drawing die 11 is convenient for keeping the axis of the steel bar. If the distance is too far, the longer the steel bar extends out of the die, the situation that the rolling end of the steel bar deviates from the axis under the action of gravity, so that the die cannot be fed for the second time may occur.
Furthermore, when the user rolls the steel bar, the steel bar can be directly rolled to be lower than the inner diameter of the last passing cold die.
Specifically, the reinforcing bar recovery mechanism includes a reel structure 14 and a reinforcing bar cutting structure 13. The winding drum structure 14 and the steel bar cutting structure are arranged on the frame 1 through a sliding block, and the sliding block moves linearly on the frame 1 under the driving of an electric push rod 7 or an air cylinder and moves to the position on the same line or not on the same line with the cold-drawing die 11. In particular, the direction of the slide blocks on which the reel structure 14 and the reinforcing bar cutting structure are located is perpendicular to the direction of the cold-drawing die 11. The purpose of this structure is, when the straight line reinforcing bar that will cut short directly, let reel mechanism not be on the same line with cold-drawing mould 11, and let reinforcing bar cutting structure and cold-drawing mould 11 be on the same line, realize cutting off.
When the winding is needed, the sliding block moves to enable the winding drum structure 14 and the cold-drawing die 11 to be located on the same line. In this embodiment, the reinforcing bar cuts off the structure and adopts current conventional structure can.
The reel structure 14 is also the same as the prior art, and is a reel driven by the rotation of the motor, when the reinforcing steel bar passes through the last cold-drawing die 11, the machine is stopped, the chain on the reel is connected with the front end of the reinforcing steel bar, then the machine is started, and the reel rotates to drive the whole reinforcing steel bar to be wound.
The working process of this embodiment is as follows:
when the cold-drawing die is used, according to the diameter of the steel bar before cold-drawing and the diameter of the steel bar after cold-drawing, whether one cold-drawing die 11 is needed for cold-drawing or a plurality of cold-drawing dies 11 are needed for cold-drawing is selected, and the cold-drawing dies 11 with corresponding specifications are installed on the installation blocks connected with the lifting device 12. The front end of the steel bar is rolled and fed into a first cold-drawing die 11 through a guide wheel 2 and a feeding disc 6, then distance adjustment is carried out, and the two feeding discs 6 are adjusted properly according to the size of the steel bar. And controlling the position of the winding drum according to the requirement of whether the winding drum is required. After finishing, starting the feeding mechanism, the two feeding plates 6 rotate to drive the reinforcing steel bars to feed forwards, and cold drawing is realized through one cold drawing die 11 or continuously through a plurality of cold drawing dies. According to the above embodiment, alright realize the utility model discloses well. It is worth to say that, on the premise of the above structural design, in order to solve the same technical problem, even if some insubstantial changes or retouching are made in the utility model, the essence of the adopted technical scheme is still the same as the utility model, so it should be in the protection scope of the utility model.
