Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding devices, in particular to an automatic feeding machine for a heating furnace. Background Art

[0002] The production of metal workpieces generally requires two processes: heating and punching. Since the cylindrical blanks used to make metal workpieces are relatively hard and not suitable for punching, they need to be heated first. When the cylindrical blanks are heated, they need to be placed in a heating furnace and heated to a preset temperature using the principle of induction heating. Punching is then performed and an automatic loader is required to feed the cylindrical blanks into the heating furnace.

[0003] The existing method for loading columnar blanks mainly adopts a push plate loading mechanism, which utilizes the multi-stage lifting of the push plate machine to achieve regular arrangement of the columnar blanks, so as to facilitate feeding them into the heating furnace for heating. However, the existing push plate loading mechanism can only transport the columnar blanks to the furnace mouth of the heating furnace, and does not have a pushing function. It is impossible to push the columnar blanks from the heating furnace mouth into the heating furnace, resulting in that this process still requires workers to feed the columnar blanks into the heating furnace, which not only wastes manpower, but also affects the feeding efficiency of the columnar blanks.

[0004] Therefore, it is necessary to propose an automatic feeding machine for a heating furnace so that the columnar blank can be fed into the heating furnace, thereby saving manpower and improving the feeding efficiency of the columnar blank. Utility Model Content

[0005] The utility model aims to solve the problem that the existing push plate machine feeding mechanism cannot feed the columnar blank into the heating furnace, resulting in low feeding efficiency of the columnar blank. An automatic feeding machine for the heating furnace is now provided.

[0006] The technical solution of the utility model is:

[0007] An automatic loader for a heating furnace comprises a frame, a plate pusher loading mechanism and a horizontally placed conveyor belt are installed on the frame, the conveyor belt is arranged on the top of the plate pusher loading mechanism, the top of the frame is fixedly connected with a support platform, the support platform is located at the end of the conveyor belt, the support platform is provided with a fixed groove for accommodating columnar blanks, a pusher plate is slidably connected in the fixed groove, and a feeding device is installed on the support platform, and the feeding device drives the pusher plate to slide in the fixed groove.

[0008] Furthermore, a first slide rail is provided at the bottom of the fixing groove, and the first slide rail is laid along the axial direction of the fixing groove.

[0009] Furthermore, the fixing groove is a semicircular shape with the opening facing upward.

[0010] Furthermore, a limit plate is provided between the conveyor belt and the supporting platform, a second vertically placed slide rail is fixed on the frame, and the limit plate is slidably connected to the frame via the second slide rail.

[0011] Furthermore, the frame is installed with a cylinder, and the cylinder drives the limit plate to slide on the second slide rail.

[0012] Furthermore, the frame is provided with a controller, a photoelectric sensor is provided in the fixing slot, and the controller receives an electrical signal sent by the photoelectric sensor.

[0013] Furthermore, the feeding device is a telescopic cylinder, and the controller controls the start and stop of the feeding device and the start and stop of the cylinder according to the electrical signal of the photoelectric sensor.

[0014] The utility model discloses an automatic feeding machine for a heating furnace. The feeding mechanism of the push plate machine feeds the columnar blank onto the conveyor belt. The conveyor belt transports the columnar blank horizontally to the end of the conveyor belt. The columnar blank enters the fixed groove. The push plate in the fixed groove pushes the columnar blank to move under the drive of the feeding device, so that the columnar blank is fed into the heating furnace for heating. Compared with the traditional technology, the technical scheme can feed the columnar blank into the heating furnace, completes the feeding, feeding and pushing processes of the columnar blank, saves manpower and improves the feeding efficiency of the columnar blank.

[0020] like Figure 1 and Figure 2As shown, this embodiment provides an automatic loader for a heating furnace, including a frame 1, the frame 1 is equipped with a push plate loading mechanism 2 and a horizontally placed conveyor belt 3, the conveyor belt 3 is arranged on the top of the push plate loading mechanism 2, the top of the frame 1 is fixedly connected with a support platform 4 by screws, the support platform 4 is located at the end of the conveyor belt 3, the support platform 4 is provided with a fixed groove 5 for accommodating a columnar blank, a push plate 6 is slidably connected in the fixed groove 5, and a feeding device 7 is installed on the support platform 4, and the feeding device 7 drives the push plate 6 to slide in the fixed groove 5.

[0021] Preferably, a first slide rail 8 is provided at the bottom of the fixing groove 5 , and the first slide rail 8 is laid along the axial direction of the fixing groove 5 , and the first slide rail 8 is screwed to the bottom of the fixing groove 5 .

[0022] Preferably, the fixing groove 5 is a semicircular shape with an upward opening, which can better adapt to the shape of the columnar blank and facilitate fixation.

[0023] Preferably, a limit plate 9 is provided between the conveyor belt 3 and the supporting platform 4 , a second vertically placed slide rail 10 is fixed by screws on the frame 1 , and the limit plate 9 is slidably connected to the frame 1 via the second slide rail 10 .
