Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rolling device, in particular to an automatic feeding and heating rolling device and method. BACKGROUND

[0002] In the process of feeding and heating rolling of rotary blade blank, the existing technology often uses a cylinder to push the rectangular (or one end large and one end small) blank into the medium-frequency induction furnace for heating, and then the heated blank is introduced into a storage platform, and then an operator clamps it into a rolling mill to form a blade edge. In this process, the number of blanks discharged from the medium-frequency heating furnace at a time is several and indefinite due to the temperature decay, and the temperature of the blanks clamped into the rolling mill at different times is inconsistent, which can easily lead to inconsistent geometric shapes, and the deviation of the placement position of the manually clamped blank can lead to the deviation of the geometric shape of the rolled workpiece.

[0003] Therefore, in order to better realize the automatic feeding and heating rolling operation, an automatic feeding and heating rolling device and method are needed. SUMMARY

[0004] The present application solves the technical problems of the prior art and provides an automatic feeding and heating rolling device and method.

[0005] The technical solution adopted by the present application is as follows: a processing table is provided, a controller is fixedly arranged on the top of the processing table, a blanking mechanism is further arranged on the top of the processing table, an induction heater is arranged at the discharge end of the blanking mechanism, a pushing mechanism is arranged at the discharge end of the induction heater, a feeding mechanism is arranged on one side of the pushing mechanism, and a rolling mill is arranged at the discharge end of the feeding mechanism. The controller controls the blanking mechanism to send the blank into the induction heater for heating, the heated blank is pushed into the feeding mechanism by the pushing mechanism, and the feeding mechanism sends the heated blank into the rolling mill for processing.

[0006] In a preferred embodiment, the blank is placed in the blanking mechanism, the blanking mechanism pushes the blank into the induction heater, the induction heater starts to heat the blank after sensing the blank, the heated blank is pushed to the feeding mechanism by the pushing mechanism, and finally the feeding mechanism sends the blank into the internal rolling mill for rolling processing. The device integrates the functions of blanking, heating, feeding and rolling, has high automation performance, has small temperature difference of the blank when entering the rolling mill, effectively improves the quality of the finished product, and has high work efficiency.

[0007] In a preferred embodiment, a storage box is fixedly arranged on the inner side of the bottom of the processing table, the storage box is used to store blanks or tools, guide wheels are arranged on the four bottom feet of the processing table, guide rails are arranged at the bottom of the guide wheels, and the processing table moves on the guide rails through the guide wheels, so that the processing table can be moved close to or away from the rolling mill.

[0008] In a preferred embodiment, the discharge end of the feeding mechanism is further provided with a temperature sensor, the temperature sensor is fixedly connected with the processing table through an L-shaped frame, and the output end of the temperature sensor is electrically connected with the input end of the controller. The temperature sensor is arranged to detect the temperature of the blank before entering the rolling machine. When the temperature of the blank is lower than 250 degrees Celsius or when the rolling machine rotates to the feeding position and the temperature sensor has not detected the temperature of the blank, an electrical signal is sent to the controller, and the controller controls the device to stop running. After manual adjustment, the device can be started again through the controller. In this way, the quality of the finished product can be effectively controlled, and the rolling machine can be prevented from running empty.

[0009] In a preferred embodiment, the rolling machine is further provided with a Hall sensor on the roller shaft, and the output end of the Hall sensor is electrically connected with the input end of the controller. Before the processing table is operated, the rolling machine needs to be operated first to avoid the situation that the heated blank has to wait for the rolling machine to start (which will cause the temperature of the blank to drop and may not meet the rolling temperature requirement). Therefore, before the device is operated, if the Hall sensor does not detect the rotation of the roller shaft of the rolling machine, the Hall sensor sends an electrical signal to the controller, the controller controls the device to stop running, and an alarm is given to prompt that the rolling machine has not started.

[0010] In a preferred embodiment, the blanking mechanism comprises a guide frame, a box and a first cylinder. The guide frame is fixed on the top of the processing table. The box is detachably arranged on the top of the guide frame by bolts. The extension shaft end of the first cylinder is fixedly provided with a push frame, and the push frame corresponds to the position of the blank at the bottom end of the box. The bottom end of the box corresponds to the position of the feeding end of the induction heater. A plurality of blanks are manually stacked in the box. When blanking, the first cylinder drives the push frame to push the blank at the bottom end of the box into the induction heater. Then the first cylinder drives the push frame to reset. At this time, the stacked blanks in the box fall under the action of gravity. The first cylinder drives the push frame to push the blank out of the guide frame again. When continuously operating, the first cylinder continuously pushes the blank out of the guide frame. The next blank pushes the previous blank to move into the induction heater for heating. Through the continuous and uninterrupted blanking mode, the blanks are pushed and blanked. This not only avoids the accumulation of blanks during blanking, but also improves the blanking efficiency.

[0011] In a preferred embodiment, the push mechanism comprises a second cylinder and a push plate. Since it is necessary to reduce the overall length of the processing table, the feeding mechanism and the induction heater are arranged side by side. When the blank comes out of the discharge end of the induction heater, the second cylinder can drive the push plate to push the blank to move to the feeding mechanism. The push mechanism plays a role in transferring the blank.

[0013] In a preferred implementation form, in order to avoid the deviation of the blank during the processing, which causes part of the blank not to be processed or the blank to directly drop out of the rolling mill, a correction mechanism is further arranged at the feeding port of the rolling mill, and the correction mechanism is used for correcting the position of the blank so that the blank is located at the middle part of the rolling mill.

[0015] In a preferred implementation form, when the blank is fed onto the support plate, the correction strip guides the blank into the gap through the arc edge, at this time, the tension spring pulls the correction strip to move towards the limiting groove, the correction strip cooperates with the limiting groove to position the blank at the middle part of the rolling mill, thereby avoiding incomplete rolling or falling during rolling.

[0016] The application further provides a rolling method for a blank based on the automatic feeding and heating rolling device, which comprises the following steps:

[0017] Before the processing table operates, the rolling mill needs to operate first, so as to avoid that the blank after being heated needs to wait for the rolling mill to start (which will cause the temperature of the blank to drop and may not reach the required temperature for rolling), therefore, before the device operates, if the roller shaft of the rolling mill does not rotate, the Hall sensor sends an electric signal to the controller, the controller controls the device to stop operating and performs an alarm to prompt that the rolling mill has not started;

[0018] The blank is manually stacked in the magazine, when blanking, the first cylinder drives the push frame to push the blank at the bottom end of the magazine into the induction heater, then the first cylinder drives the push frame to reset, at this time, the stacked blanks in the magazine fall under the action of gravity, the first cylinder drives the push frame to push the blank out of the guide frame again, when continuously operating, the first cylinder continuously pushes the blank out of the guide frame, the next blank pushes the previous blank to move into the induction heater for heating;
