Description

Technical Field

[0001] The utility model relates to the technical field of forging blank feeding, in particular to an improved driving shaft feeding device. Background Art

[0002] At present, for the production of driving shaft (half shaft) forgings, a high-frequency induction heating furnace is mainly used to heat the bar stock, and then it is sent into a press for forging. For the feeding of the bar stock, a feeding device is used. When the blank stock has magnetism, the existing feeding device is prone to adhesion and cannot be reliably and accurately separated, resulting in an unreliable feeding process. There are often situations where the feeding is not in place or the feeding is not successfully in place, causing the disadvantage of manual intervention. For example, a bar stock induction heating automatic loading and unloading device disclosed in Patent Application No. 202111131908.2, as Figure 1 shown, the flat plates between the workstations on the feeding rack are placed in parallel. The side part of the feeding rack is installed on one side of the porous induction heating furnace. The number of workstations is the same as and corresponds one by one to the number of heating through holes of the porous induction heating furnace. The blank stock is ejected by the rapid upward movement of the feeding cylinder. Due to the inclined surface at the top of the cylinder, the blank stock moves forward and falls into the notch of the corresponding workstation. When feeding in sequence in a cycle, as long as the feeding cylinder of the workstation to be fed is controlled to be in the downward position, the bar stock can fall into the groove of the corresponding workstation, and then under the action of the rear pushing cylinder, the bar stocks on each workstation are automatically sent into the respective heating through holes of the induction heating furnace for sequential cyclic heating. After heating is completed, according to the above actions, the heated bar stock in the induction furnace is ejected and falls into the unloading device to complete the feeding action of the blank bar stock. However, the problem of this mechanism is that the hot-rolled round steel bar stock often has magnetism. At the feeding cylinder, due to the problem of magnetic adhesion, the bar stock cannot be effectively separated after being ejected or cannot accurately fall into the corresponding workstation groove after separation. Sometimes, when the bar stock is ejected by the feeding cylinder and is skewed, it will exceed the workstation to be fed, enter the next workstation or stay on the subsequent flat plate, and often requires manual inspection and manual intervention to place it in place, seriously affecting the stability of the process. If the heated blank stock cannot be effectively ejected, it will cause the bar stock to be overheated and scrapped, and in severe cases, it will damage the induction heating furnace.

[0020] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention, and should not be construed as limiting the present invention.

[0021] like Figure 2-3 As shown, an improved drive shaft feeding device proposed in this embodiment includes:

[0022] The storage rack 1 is used to store bar materials, with its feed end higher than the discharge end and tilted, and a loading position 3 is provided at the discharge end of the storage rack 1;

[0023] The feeding end of the loading rack 2 is connected to the discharging end of the storage rack 1. A plurality of workstations are arranged on the loading rack 2 at intervals, and a flat plate is provided upstream of each workstation. The feeding end of the flat plate is tilted higher than the discharging end.

[0024] Multiple feeding mechanisms are located at the lower end of the feeding position 3 and the lower end of the work station;

[0025] The liftable blocking mechanism is located at the rear side of the loading mechanism at the lower end of the loading position 3. When the blocking mechanism is raised, it can separate the rods at the discharge end of the storage rack 1 from the rods at the rear side thereof.

[0026] In this way, by tilting the flat plate at a certain angle so that the loading end is higher than the discharging end, it can play a role in limiting and stopping the blank rod 14, and can reliably ensure that the blank rod 14 is delivered into place; and a liftable stop mechanism is provided on the rear side of the loading mechanism at the lower end of the loading position 3. When the stop mechanism is raised, the rods at the discharging end of the storage rack 1 and the rods on its rear side can be separated, which can effectively separate the blank rod 14 and ensure that the blank is delivered to the loading position 3 accurately and reliably, solving the problems of loading instability and inadequate loading caused by the adhesion of magnetic rod materials.

[0027] Specifically, the feeding mechanism is configured as a feeding cylinder, wherein the top of the feeding cylinder is provided with an inclined surface.

[0028] In this embodiment, the material blocking mechanism is a material blocking cylinder 13. The top of the material blocking cylinder 13 is also provided with an inclined surface. After the blank bar stock 14 is fully loaded on the stock rack 1, since the feeding end of the stock rack 1 is higher than the discharging end and is inclined, the blank bar stock 14 on the stock rack 1 automatically slides down from the inclined surface of the stock rack 1 to the loading position 3 by gravity. In order to ensure that the loading cylinder at the lower end of the loading position 3 can smoothly lift the blank bar stock 14, the material blocking cylinder 13 needs to rise before the loading cylinder at the lower end of the loading position 3 pushes the material. Then, under the action of the inclined surface of the top block of the material blocking cylinder 13, the blank bar stock 14 at the rear is separated from the bar stock to be loaded at the discharging end of the stock rack 1 front and back. Then, the loading cylinder at the lower end of the loading position 3 is lifted. This not only ensures the smooth progress of loading, but also the material blocking cylinder 13 can be lifted at any time during use when problems occur, preventing the bar stock from rolling to the bottom.

[0029] In one specific embodiment, as Figure 2 shown, the multiple workstations include workstation I 4, workstation II 5, and workstation III 6. The loading mechanism includes loading cylinder I 7, loading cylinder II 8, and loading cylinder III 9 that respectively correspond to the loading position 3, workstation II 5, and workstation III 6 in sequence. The flat plates located upstream of workstation I 4, workstation II 5, and workstation III 6 are flat plate I 10, flat plate II 11, and flat plate III 12 respectively.

[0030] By placing the flat plate I 10, flat plate II 11, and flat plate III 12 at a certain inclined angle so that the feeding end is higher than the discharging end, it can play a role in limiting and blocking the blank bar stock 14. When feeding is required at workstation I 4, the loading cylinder II 8 drops, and the loading cylinder I 7 pushes the blank material at the discharging end of the stock rack 1 upward. Under the action of gravity, it falls into workstation I 4 through the flat plate I 10; when feeding at workstation II 5, both the loading cylinder III 9 and the loading cylinder II 8 drop, and then the loading cylinder I 7 and the loading cylinder II 8 push upward in sequence to send the blank bar stock 14 to workstation I 4 first and then to workstation II 5 to complete the feeding at workstation II 5; when feeding at workstation III 6, both the loading cylinder III 9 and the loading cylinder II 8 drop, and then the loading cylinder I 7, the loading cylinder II 8, and the loading cylinder III 9 push out in sequence to send the blank bar stock 14 to workstation I 4 first, then to workstation II 5, and finally to workstation III 6 to complete the feeding of the blank bar stock 14 at workstation III 6. In this way, it can reliably ensure that the blank bar stock 14 is fed in place, and the magnetic bar stock can be effectively separated by the material blocking cylinder 13. It overcomes the problem of sticky material of the magnetic raw material, resulting in unstable feeding and incomplete feeding.

[0031] It should be noted that the improved drive shaft loading device in this embodiment is mainly applied to the forging production of the drive shaft of agricultural machinery, realizing automatic multi-station automatic feeding and improving the reliability and stability of feeding.

[0032] Among them, for the convenience of operators to control, a control mechanism is further included. The control mechanism is communicably connected to the feeding mechanism and the material blocking mechanism, and automatic feeding is realized through the control of the control mechanism.
