[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Example

[0019] For the seatbelt reinforcement plate progressive die machining device, please refer to... Figures 1-3The device includes a base 1, a top seat 2, a mold assembly, a drive assembly, a cutting assembly, a pushing assembly, and a receiving assembly. The base 1 serves as the basic support component of the device, and several guide grooves 13 are provided on the top for mounting the lower mold 4 and restricting its movement direction. The base is provided with mounting brackets 3 on both sides for fixing the power element that drives the top seat to move.

[0020] The top seat 2 is located above the base and is driven to move up and down by the hydraulic cylinder 31 at the bottom of the mounting frame 3; several upper molds 21 are arranged axially at the bottom of the top seat, which correspond to the lower mold 4 to form a stamping station.

[0021] Specifically, the mold assembly consists of a lower mold 4 and an upper mold 21. The lower mold 4 is inserted into the guide groove 13 of the base, and its bottom is connected to the bottom of the guide groove through a built-in damper of spring 2 14 to achieve elastic buffering. Guide plates 41 are provided on both sides of the top of the lower mold to ensure precise mold closing between the upper and lower molds.

[0022] Specifically, the top two sides of the base of the limiting component are arranged with limiting sleeves 5 and built-in springs 51; the bottom of the top seat is provided with limiting posts 12. When the mold is closed, the limiting posts are inserted into the limiting sleeves, and the springs buffer the impact force to avoid excessive compression of the mold.

[0023] The bottom end of the top seat of the cutting and removing assembly is provided with a cutting section and a removing section in sequence along the discharge direction. The cutting section includes a hydraulic cylinder 11 and a spiral cutting section 111, which are used to cut the contour of the formed workpiece; the removing section includes a hydraulic cylinder 10 and a cutting blade 101, which are used to remove the processing residue.

[0024] The top of the base is located below the cutting section and has a pushing section, including a hydraulic cylinder 2 9 and a U-shaped pushing frame 91, which is used to push the cut workpiece to the discharge plate 6 and drop it into the receiving box 7; the tail end of the base is located near the cutting section and has a waste box 8, which is used to collect the waste generated by cutting.

[0025] Working principle

[0026] 1. Feeding stage: The reinforcing plate raw material is conveyed along the upper part of the lower mold 4 to the discharge direction through an external conveyor to ensure that the raw material enters each stamping station accurately.

[0027] 2. Stamping: Control the extension of hydraulic cylinder 31, which drives the top seat 2 to move down, and the upper mold 21 and the lower mold 4 close together to stamp the raw material; at this time, the lower mold compression spring 14 moves down, the damper reduces vibration, and the limit post 12 inserts into the limit sleeve 5 to compress the spring 51 to avoid over-stamping.

[0028] 3. Cutting process: After forming, hydraulic cylinder 4 11 drives the back-shaped cutting part 111 to move down and cut the contour of the formed workpiece; after cutting, the workpiece is stuck at the tail end of the base 1 due to gravity, and the remaining material moves up and reset with the lower mold under the action of spring 2 14.

[0029] 4. Workpiece collection: Control the extension of hydraulic cylinder 29, and push the workpiece along the top of the base to the inclined discharge plate 6, and finally fall into the receiving box 7.

[0030] 5. Waste disposal: The remaining material continues to be conveyed to the area below the cutting section. The hydraulic cylinder 310 drives the cutting blade 101 to move down and cut off the remaining material. The waste material falls directly into the waste bin 8.

[0031] 6. Reset Cycle: Each hydraulic cylinder resets, the top seat moves upward, and the device enters the next processing cycle.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
