Compared with ordinary steel plates, high-strength steel plates have higher yield strength and tensile strength, which meet the requirements of improving automobile safety and collision performance. The original cold stamping forming process can no longer meet the automotive industry's needs for technology and production development, which has spawned a new type of forming technology for high-strength steel plates - hot stamping forming technology.

[0003] In the existing stamping process, a driving device drives the die to approach the punch to achieve forming. However, after the processing, the finished product is easily stuck in the groove of the die, which makes it difficult to remove. There is room for improvement. Utility Model Content

[0006] As a further preferred embodiment of the present technical solution, the top outer wall of the mounting plate is fixedly connected to a support frame, the top outer wall of the support frame is fixedly installed with a hydraulic cylinder, the output end of the hydraulic cylinder is fixedly connected to a punch, the outer wall of one end of the punch is fixedly connected to a hook plate, and one end of the hook plate is located below the movable end of the push plate.

[0007] After the processing is completed, the parts can be pushed out of the die, and then slide down to the outside along the slope of the discharge assembly. The operation is convenient enough, which is beneficial to increase the processing efficiency of the device. The hydraulic cylinder is controlled to drive the punch to return to its original position. During this period, the hook plate will move synchronously with the punch. Since one end of the push plate is connected to the connecting plate through a hinge, when the hook plate drives the other end of the push plate to move upward, the push plate will flip over, and the stamped finished product will be lifted up by the push plate, and then slide to the outside along the slope of the push plate.

Because the moving block sleeve is arranged outside the moving rod, it can be ensured that the moving block can be arbitrarily away from or close to the die, ensuring that the device can adapt to the positioning of raw materials for processing different parts. Then, by rotating the two bolts, the two bolts can contact the sliding track and the moving rod respectively. Under the action of friction, the position of the moving rod and the limit sleeve can be fixed. At this time, positioning can be achieved by aligning one corner of the material with the limit sleeve, thereby avoiding defects in the finished product caused by material position deviation.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1 and Figure 3 As shown, in this embodiment, a hot stamping die of high-strength steel plates for automobile parts includes a mounting plate 1, which is characterized in that a die 2 is fixedly mounted in the middle of the top outer wall of the mounting plate 1, a discharge assembly 8 is mounted inside the die 2, and the discharge assembly 8 includes a connecting plate 801 fixedly connected to one end of the top outer wall of the mounting plate 1, a push plate 802 is rotatably connected to the top of the connecting plate 801 through a hinge, both ends of the push plate 802 extend to the outside of the die 2, and a receiving groove 803 is provided on the bottom inner wall of the die 2, and the push plate 802 can just enter the receiving groove 803.

[0024] The top outer wall of the mounting plate 1 is fixedly connected with a support frame 3, the top outer wall of the support frame 3 is fixedly installed with a hydraulic cylinder 4, the output end of the hydraulic cylinder 4 is fixedly connected with a punch 5, one end of the punch 5 is fixedly connected with a hook plate 804, and one end of the hook plate 804 is located below the active end of the push plate 802. (The discharge assembly 8 does not have to be set in the concave die, depending on the specific production situation on site. The mold in which the part will be stuck after molding is set at the bottom, and the discharge assembly 8 is also set in the mold, and the installation method is the same)

[0025] Start the hydraulic cylinder 4 on the top of the support frame 3, and the hydraulic cylinder 4 drives the punch 5 to move downward until the punch 5 drives the material and the die 2 to overlap, and then start the liquid cooling device in the mold, the finished product can be quickly cooled and shaped, and then control the hydraulic cylinder 4 to drive the punch 5 to return to its original position. During this period, the hook plate 804 will move synchronously with the punch 5. Since one end of the push plate 802 is connected to the connecting plate 801 through a hinge, when the hook plate 804 drives the other end of the push plate 802 to move upward, the push plate 802 will flip over, and the stamped product will also be lifted up by the push plate 802, and then slide to the outside along the slope of the push plate 802, which is more convenient to operate and conducive to improving production efficiency.

[0026] like Figure 2 and Figure 4 As shown, a positioning assembly 9 is installed on the outside of the die 2, and the positioning assembly 9 includes a sliding track 901 fixedly connected to the top of the outer wall of one side of the die 2, a moving rod 902 is provided on the outer sliding sleeve of the sliding track 901, a moving block 903 is provided on the outer sliding sleeve of the moving rod 902, a limiting sleeve 904 is provided on the top outer wall of the moving block 903, and a bolt 905 is threadedly connected to the bottom of the moving rod 902 and the moving block 903. The two bolts 905 can contact the outer walls of the sliding track 901 and the moving rod 902 respectively.

[0027] The upper part of the limiting sleeve 904 is configured to be in the shape of a trumpet extending outward, which can save the process of aligning the corner of the material with the corner of the limiting sleeve 904 .

[0028] The position of the limiting sleeve 904 is adjusted according to the material size, and the moving rod 902 is pushed to slide outside the sliding track 901. At this time, the moving rod 902 can move left and right along the die 2. Because the moving block 903 is sleeved on the outside of the moving rod 902, it can be ensured that the moving block 903 can be arbitrarily away from or close to the die 2, ensuring that the device can adapt to the raw material positioning work of different parts processing. Then, by rotating the two bolts 905, the two bolts 905 can contact the sliding track 901 and the moving rod 902 respectively. Under the action of friction, the position of the moving rod 902 and the limiting sleeve 904 can be fixed. At this time, as long as one corner of the material is aligned with the limiting sleeve 904, the positioning can be achieved, avoiding the deviation of the material position and causing defects in the finished product.

[0029] like Figure 1 and Figure 2 As shown, multiple extension plates 6 are provided on the top of the outer walls at both ends of the support frame 3, and a reinforcement rod 7 is slidably inserted into the multiple extension plates 6, and one end of the multiple reinforcement rods 7 is fixedly connected to the outer wall of the top of the punch 5.

[0031] like Figure 3 As shown, a corner at the bottom of the hook plate 804 is fixedly connected with a reinforcing plate 805, which can prevent the lower part of the hook plate 804 from bending randomly.

[0032] like Figure 1 and Figure 2 As shown, the push plate 802 is made of a copper alloy material with high thermal conductivity, so that the material inside the die 2 can be cooled more quickly.

[0033] The utility model provides a high-strength steel plate hot stamping die for automobile parts, and the specific working principle is as follows:

[0034] When the device is working, first adjust the position of the limit sleeve 904 according to the material size, push the moving rod 902 to make it slide outside the sliding track 901, and then the moving rod 902 can move left and right along the die 2, and because the moving block 903 is sleeved on the outside of the moving rod 902, it can be ensured that the moving block 903 can be arbitrarily away from or close to the die 2, so that the device can adapt to the raw material positioning work of different parts processing, and then by rotating the two bolts 905, the two bolts 905 can contact the sliding track 901 and the moving rod 902 respectively, and the position of the moving rod 902 and the limit sleeve 904 can be fixed under the action of friction. At this time, positioning can be achieved by aligning one corner of the material with the limit sleeve 904, avoiding The displacement of the material position causes defects in the finished product. Then the hydraulic cylinder 4 on the top of the support frame 3 is started, and the hydraulic cylinder 4 drives the punch 5 to move downward until the punch 5 drives the material and the die 2 to overlap. Then the liquid cooling device in the mold is started, and the finished product can be quickly cooled and shaped. Then the hydraulic cylinder 4 is controlled to drive the punch 5 to return to its original position. During this period, the hook plate 804 will move synchronously with the punch 5. Since one end of the push plate 802 is connected to the connecting plate 801 through a hinge, when the hook plate 804 drives the other end of the push plate 802 to move upward, the push plate 802 will flip over, and the stamped product will also be lifted up by the push plate 802, and then slide to the outside along the slope of the push plate 802. The operation is more convenient, which is conducive to improving production efficiency.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
