Detailed Description
The screw production apparatus of the present invention will be further described with reference to FIGS. 1 to 3.
The screw production device comprises a straightening and cutting mechanism 1 and a thread rolling mechanism 2, and the structures of the straightening and cutting mechanism 1 and the thread rolling mechanism 2 are the prior art, so the specific structure of the screw production device is not described in detail in the embodiment. The embodiment also comprises a workpiece discharging mechanism 4 and two workpiece feeding mechanisms 3.
The two thread rolling mechanisms 2 are arranged on two sides of the straightening cutting mechanism 1, namely the two thread rolling mechanisms 2 and the straightening cutting mechanism 1 are arranged in parallel, and the discharging direction of the straightening cutting mechanism 1 and the feeding direction of the thread rolling mechanism 2 are arranged on the same side.
The workpiece discharging mechanism 4 comprises a discharging frame body 41, and a discharging groove 42, a swing arm assembly 44 and a driving part 43 which are arranged on the discharging frame body 41; the feeding end of the discharging groove 42 is butted with the discharging hole of the straightening and cutting mechanism 1 so as to feed the cut workpiece; the swing arm assembly 44 comprises a rotating shaft 441 and a poking rod 442, the rotating shaft 441 is mounted on the discharging frame body 41 through a mounting plate 45, vertically corresponds to the discharging groove 42, and extends in the same direction as the discharging groove 42, one end of the poking rod 442 is inserted into or formed on the side wall of the rotating shaft 441, and the other end of the poking rod extends into the discharging groove 42; the driving member 43 is mounted on the mounting plate 45 and connected to the rotating shaft 441, and drives the rotating shaft 441 and the poke rod 442 to poke the workpiece out of the discharge chute 42.
The two workpiece feeding mechanisms 3 are respectively positioned at two sides of the workpiece discharging mechanism 4 and are provided with a feeding groove 31 and a feeding traction wheel set 32; the discharge end of the feed chute 31 is butted with the feed inlet of the thread rolling mechanism 2, a guide rod 5 is arranged between the upper notch of the feed chute 31 and the upper notch of the discharge chute 42, and the height of one side of the guide rod 5, corresponding to the feed chute 31, is lower than the height of one side of the guide rod 5, corresponding to the discharge chute 42; the feeding traction wheel set 32 comprises two isolated traction wheels 322, a traction channel 321 is formed between the two isolated traction wheels 322, and the traction channel 321 is positioned in the feeding groove 31 so as to feed the workpiece of the feeding groove 31 into the thread rolling mechanism 2. It should be noted that the drawing channel 321 has a baffle 33 therein, the baffle has an opening thereon, the opening corresponds to the drawing channel, and the height ratio of the opening is greater than the diameter of the workpiece, so that only one workpiece passes through.
When the screw rod straightening and cutting mechanism is used specifically, after a raw material passes through the straightening and cutting mechanism 1, a long-strip-shaped workpiece is formed and is sent into the discharge chute 42, the driving part 43 drives the rotating shaft 441 and the poking rod 442 to rotate so as to poke the workpiece in the discharge chute 42 into the feed chute 31, and meanwhile, the driving part 43 can also drive the rotating shaft 441 and the poking rod 442 to rotate positively and negatively so as to respectively poke the workpiece into the feed chutes 31 on the left side and the right side, so that the screw rod production efficiency is remarkably improved; the workpiece entering the feeding chute 31 falls into the drawing channel 321, and is fed into the thread rolling mechanism 2 for thread rolling operation under the action of the drawing wheel set 32. In the process, the process that the operator manually conveys the workpiece is saved, and the production cost is saved; the swing arm assembly 44 and the driving component can alternately feed the thread rolling mechanisms 2 on the left side and the right side, so that the screw machining efficiency is remarkably improved; on the other hand, the workpieces are reversely conveyed after being sent out of the discharge chute, so that the spatial arrangement of the workpiece conveying device in the length direction is remarkably reduced.
In this embodiment, the driving member 43 is set to rotate once at regular intervals, that is, the rotating frequency is the same as the frequency of a workpiece completely entering the discharge chute 42, and the driving member 43 drives the rotating shaft 441 to rotate in the forward and reverse directions to alternately feed the workpiece into the discharge chutes 42 on both sides, that is, the straightening and cutting speed is twice the thread rolling speed, so as to realize continuous production between the straightening and cutting mechanism and the thread rolling mechanism 2.
The embodiment is further configured as follows: the discharging groove 42 is an arc groove, and the rotating shaft 441 and the arc groove are of a concentric structure. With this structure, the lever 442 can be easily operated to move the workpiece in the discharge chute 42 away from the discharge chute 42.
The embodiment is further configured as follows: the plurality of the pulling levers 442 are arranged in parallel along the axial direction of the rotating shaft 441. Under this setting for the work piece receives the multiple spot when being stirred, and it can be in the state that is parallel with blown down tank 42 and break away from blown down tank 42, thereby is showing the stability that promotes swing arm subassembly 44 and dials the work piece off of blown down tank 42.
The embodiment is further configured as follows: the driving member 43 is a motor. The motor can drive the rotating shaft 441 to rotate forwards and backwards, and can realize the function of running at regular intervals.
The embodiment is further configured as follows: the guide bars 5 are provided in plural and arranged in line in the extending direction of the discharge chute 42. Under this structure, can promote the work piece and break away from the stability that enters into feed chute 31 behind the blown down tank 42.
