DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-3 As shown, a continuous stamping structure of automobile hardware parts includes a base 1, a material guide mechanism 2 is installed on the top of the base 1, a positioning assembly 3 is installed above the material guide mechanism 2, the material guide mechanism 2 includes a material guide plate 4 and a material guide frame 5, two first limiting grooves 6 and a second limiting groove 7 are respectively provided on the top of the base 1 at both sides and the rear end, a slide groove 8 is provided on the inner side of the material guide plate 4, two first support columns 9 are fixedly installed on the bottom of the two material guide plates 4 and the material guide frame 5, the first support column 9 runs through the top of the base 1, a first spring 10 is installed on the periphery of the first support column 9 and inside the base 1, two pressure rollers 11 are movably installed inside the material guide frame 5, and a motor 12 is installed at the outer end of the rotating shaft of one of the pressure rollers 11.

[0022] In this embodiment, the guide plates 4 are located in the first limiting groove 6 and are matched with each other. The two guide plates 4 are symmetrically arranged to support the raw materials so that the workpiece after stamping can be automatically demolded.

[0023] In this embodiment, the material guide frame 5 is located in the second limiting groove 7 and is matched with each other. The output shaft of the motor 12 is fixedly connected to the rotating shaft of one of the pressure rollers 11. The motor 12 drives the corresponding pressure roller 11 to rotate, so that the two pressure rollers 11 press the raw materials and convey them intermittently.

[0024] In this embodiment, the first support column 9 penetrates the interior of the base 1 and is slidable up and down. The material guide frame 5 is fixedly installed at the rear ends of the two material guide plates 4. The material guide frame 5 and the two material guide plates 4 rise and fall simultaneously. The material guide frame 5 is located in the second limit groove 7 for limit.

[0025] In this embodiment, the positioning assembly 3 includes a top plate 13, and two pressing plates 14 and an upper mold 15 are movably installed at the bottom of the top plate 13. Two second support columns 16 are installed on the top of the two pressing plates 14 and pass through the interior of the top plate 13. The outer periphery of the second support column 16 is sleeved with a second spring 17. Two slide rods 18 are movably installed at the front end of the interior of the top plate 13. A cutting knife 19 is fixedly installed at the bottom end of the two slide rods 18. Two slide rails 20 are installed at the rear of the cutting knife 19 and at the front of one of the pressing plates 14. A top plate 21 is fixedly installed on the top of the slide rod 18. The raw material is pressed by the pressing plate 14 and then stamped. At the same time, the stamped workpiece is cut out from the raw material by the cutting knife 19.

[0026] In this embodiment, the two pressing plates 14 are movably installed at the front and rear parts of the upper mold 15 respectively, and the second support column 16 passes through the interior of the top plate 13 and is arranged to slide up and down. Under the action of the second spring 17, the pressing plate 14 automatically slides downward, and the sliding of the second support column 16 causes the pressing plate 14 to shrink.

[0027] In this embodiment, the height between the upper and lower ends of the cutting knife 19 is greater than the height between the upper and lower ends of the pressing plate 14. The slide rail 20 is located at the front of the pressing plate 14 and is arranged to slide. When the cutting knife 19 contacts the workpiece, it slides upward to the same horizontal plane as the bottom of the pressing plate 14, and continues to press down through the top plate 13 so that the cutting knife 19 cuts the workpiece out for discharge.

[0028] It should be noted that the utility model is a continuous stamping structure for automobile hardware parts. When in use, the raw material passes between two pressing rollers 11 and is located between the slide grooves 8 in the two guide plates 4. When stamping, the top plate 13 is lowered by the extension and contraction of the hydraulic cylinder, and the two pressing plates 14 contact the raw material and the guide plates 4, and drive the guide plates 4 and the guide frame 5 to slide downward into the first limiting groove 6 and the second limiting groove 7, so that the first spring 10 contracts, the upper die 15 contacts the raw material and stamps, and at the same time the cutting knife 19 contacts the raw material. The material contacts and slides upward synchronously with the pressing plate 14. When it is fully stamped, the top of the cutting knife 19 contacts the top plate 13 and continues to descend to cut out the stamped workpiece. After stamping and cutting are completed, the top plate 13 rises, and the two guide plates 4 and the guide frame 5 automatically rise under the action of the first spring 10, and drive the raw material and the stamped workpiece to be demolded. By intermittently starting the motor 12 to rotate the corresponding pressure roller 11, the unstamped area of ​​the raw material is transported to the bottom of the upper die 15, and continuous stamping and automatic cutting and unloading are carried out in sequence.

[0029] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
