Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and in particular to a hot stamping equipment and method for spiral bevel gears. Background Art

[0002] Spiral bevel gears have the advantages of high transmission efficiency, stable transmission ratio, large arc overlap coefficient, high load-bearing capacity, smooth transmission, reliable operation, compact structure, energy saving and material saving, space saving, wear resistance, long life and low noise. The tooth profile of spiral bevel gears is arc shape, and is generally conical.

[0003] When the spiral bevel gear is hot stamped on the hot stamping equipment, it needs to be heated in a heating box and then removed for hot stamping. However, the blank material needs to be taken out with a tool, but the temperature difference between the tool and the hot blank is large. When it comes into contact with the tool, it will cause a large local temperature drop, which in turn affects the hot stamping formability and the hot stamping quality. In addition, the existing hot stamping equipment is not convenient enough when installing the stamping die. It is often fixed with multiple bolts, which is inconvenient to operate and cannot achieve rapid installation and disassembly of the die. Summary of the invention

[0017] Step 2: Heating of the workpiece: The workpiece is driven into the heating box for heating by moving the heating closed door;

[0018] Step 3: Removal of the workpiece: Start the electric telescopic rod to drive the heated workpiece to move above the stamping table. At the same time, the movable support plate loses its support, and the workpiece falls into the mold under the restriction of the first limit plate and the second limit plate;

[0019] Step 4: Hot stamping of the workpiece: hot stamping operation is performed on the workpiece dropped into the die.

[0020] Compared with the prior art, the invention has the following advantages:

[0021] 1. After the workpiece blank is heated, it can be taken out of the heating box by moving the heating closed door and moved to the working point, which can avoid the use of additional tools to pick up and place the workpiece, thereby avoiding the workpiece and the tool from contacting with a large temperature difference, ensuring that the workpiece will not be locally cooled too much, thereby ensuring the quality of hot stamping.

[0022] 2. When the heated closed door drives the workpiece to move, it will contact the driving bearing block, which will also drive the driving bearing block to move. As the driving bearing block moves, it will drive the push-up connecting block to move upward, and under the action of the push-up connecting block, it will drive the closed movable plate to move upward, and under the action of the closed movable plate, it will drive the connecting movable plate to move upward, and then under the action of the connecting movable plate, it can drive the first limit plate strip and the second limit plate strip to move, and then it can limit the workpiece and adjust it to ensure the accuracy of its position. At the same time, the connecting movable plate will also drive the movable support plate to move so that it no longer supports the workpiece. In this way, under the restriction of the first limit plate strip and the second limit plate strip, the workpiece can fall smoothly into the mold, which is convenient for stamping operation.

[0023] 3. In addition, when the driving bearing block moves, the push-down linkage rod will drive the matching movable plate to move downward. As the matching movable plate moves downward, a negative pressure can be formed in the adsorption matching cavity under the action of the adsorption plug plate, so that the mold can be firmly adsorbed and fixed on the stamping table, realizing the fixed installation of the mold, which is very convenient. When no stamping is performed, the mold is in an active state, which is convenient for installation and disassembly of the mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] A hot stamping method for a spiral bevel gear comprises the following steps:

[0047] Step 1: Placing the workpiece: placing the workpiece to be punched on the movable support plate 9;

[0048] Step 2: Heating the workpiece: The workpiece is driven into the heating box 11 for heating by moving the heating closed door 2;

[0049] Step 3: Removal of the workpiece: Start the electric telescopic rod 13 to drive the heated workpiece to move above the punching table 19, and at the same time, the movable support plate 9 loses its support, and the workpiece falls into the mold under the restriction of the first limit plate 7 and the second limit plate 82;

[0050] Step 4: Hot stamping of the workpiece: hot stamping operation is performed on the workpiece dropped into the die.

[0051] When hot stamping the spiral bevel gear, the workpiece to be stamped is placed on the movable support plate 9. At this time, the two movable support plates 9 are in a closed state. Then the stamping die is placed on the stamping table 19 and positioned by the limit ring plate 191. The electric telescopic rod 13 is started to drive the heating closed door 2 to move in the direction of the heating box 11. The heating box 11 is closed, and the heating box 11 can be started to heat the workpiece. After the heating is completed, the electric telescopic rod 13 is started again to drive the heating closed door 2 to move in the opposite direction, and the workpiece can be taken out to avoid the workpiece from contacting the support tool with a large temperature difference, thereby avoiding the local temperature from dropping too fast, ensuring Due to the hot stamping formability, the heated closed door 2 will contact the matching protrusion 35 when it moves. At this time, the plug-in protrusion 381 is plugged into the connecting socket 51, so that the heated closed door 2 will drive the contact matching block 33 to move, and then drive the driving bearing block 3 to move. As the driving bearing block 3 moves, the bearing movable block 37 will be driven to move upward under the action of the connecting movable rod 36, and then the push-up connecting block 38 can be driven to move upward under the action of the bearing movable block 37. In addition, as the contact matching block 33 moves, it will also drive the push-up connecting block 38 to move, and as the push-up connecting block 38 moves upward, it will drive the closed movable The plate 5 moves upward, and the movement of the driving bearing block 3 will also drive the matching movable plate 4 to move downward under the action of the push-down linkage rod 392. As the matching movable plate 4 moves downward, a negative pressure can be formed in the adsorption matching cavity 192 under the action of the adsorption plug plate 42, so that the mold can be firmly fixed on the stamping table 19, realizing convenient fixation of the mold, and when no stamping is performed, the mold is in an active state, which is convenient for installation and disassembly. The upper push block 55 will contact the second arch frame 67 during the upward movement of the closed movable plate 5, so that the second arch frame 67 will be driven to move upward under the action of the upper push block 55, thereby driving the connecting movable plate 6 to move upward Movement, with the upward movement of the connecting movable disk 6, the first limit strip 7 and the second limit strip 82 will be driven to move toward the workpiece under the action of the cooperating driving rod 68, and the workpiece can be limited while the position of the workpiece is adjusted. As the connecting movable disk 6 moves upward, the two movable support plates 9 will be driven to move away from each other under the cooperation of the cooperating cavity 66 and the plug-in linkage rod 93, so that the two are separated and no longer support the workpiece. When the workpiece moves to the top of the mold, it completely loses support for the workpiece. In this way, the workpiece falls into the mold under the restriction of the first limit strip 7 and the second limit strip 82, which is convenient for stamping.
