DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0021] Referring to Figs. 1-3 A fine blanking die for an automobile air conditioner compressor valve plate, comprising a base 1, the base 1 is provided with a mounting hole 2 on the top, and a lower die 3 is slidably arranged in the mounting hole 2, the base 1 is internally provided with a driving assembly for driving the lower die 3 to move up and down, the lower die 3 is provided with a preset hole 4 penetrating therethrough, the base 1 is internally fixedly provided with a top plate 5 located directly below the lower die 3, and the top surface of the top plate 5 is fixedly connected with a top block 6 matched with the preset hole 4;

[0022] A communication hole 7 is arranged on one side of the upper part of the installation hole 2, and a waste box 8 for collecting waste is arranged at the other end of the communication hole 7. A scraper 9 and a pushing assembly are arranged on the other side of the upper part of the installation hole 2, and the pushing assembly is used to drive the scraper 9 to move close to or away from the communication hole 7.

[0023] With reference to Figs. 1-3 The automobile air conditioner compressor valve plate fine blanking die further comprises a fine blanking assembly 10 arranged above the base 1 and used to cooperate with the lower die 3. The fine blanking assembly 10 is a prior art, which comprises a fixing frame, a hydraulic cylinder, an upper die and the like. The fine blanking assembly 10 is a prior art, and thus will not be described in detail.

[0024] In use, the plate material is first placed on the top surface of the lower die 3, and then the fine blanking assembly 10 is used to start stamping. After stamping, the waste falls into the preset hole 4, and the finished product is located on the top surface of the lower die 3. At this time, the lower die 3 is driven to move upward by the driving assembly, so that the finished product can be conveniently taken out. After the finished product is taken out, the lower die 3 is driven to move downward by the driving assembly until the top surface of the lower die 3 is flush with the communication hole 7. At this time, the top block 6 on the top plate 5 lifts the waste in the preset hole 4, the top plate 5 is driven to move by the pushing assembly, and the waste falls into the waste box 8 through the communication hole 7, thereby completing the collection of the waste.

[0025] With reference to Figs. 1-3 The driving assembly comprises a lead screw 11 rotatably arranged at the bottom of the base 1. A moving block 12 is threadedly sleeved on the lead screw 11. The top of the moving block 12 is hingedly connected with a connecting rod 13. The other end of the connecting rod 13 is hingedly arranged at the bottom of the lower die 3. The driving assembly drives the moving block 12 to move by rotating the lead screw 11, so that the one end of the connecting rod 13 moves horizontally, and the other end of the connecting rod 13 drives the lower die 3 to move up and down.

[0026] In order to ensure the stability of the force borne by the lower die 3, the number of moving blocks 12 on the lead screw 11 is one, and the two moving blocks 12 are symmetrically threadedly sleeved on the two ends of the lead screw 11. The two connecting rods 13 are respectively hingedly arranged on the two sides of the bottom surface of the lower die 3, thereby improving the stability of the device.

[0027] The threads on the two ends of the lead screw 11 are equidistant and opposite, so that when the lead screw 11 rotates, the two moving blocks 12 on the two sides move the same distance, thereby ensuring the stability of the movement of the lower die 3.

[0028] An auxiliary hole 14 is arranged on the side of the upper part of the installation hole 2 away from the communication hole 7. The pushing assembly comprises an electric push rod 15 fixedly installed in the auxiliary hole 14. The scraper 9 is fixedly connected to the telescopic end of the electric push rod 15. The movement of the scraper 9 is realized by the electric push rod 15, so that the waste is pushed into the communication hole 7.

[0029] The scraper 9 is arc-shaped, so that the waste can be concentrated in the middle of the scraper 9 during pushing, and then be collected conveniently, and the scraper 9 can be stored in the auxiliary hole 14 when not in use.

[0030] The bottom surface of the scraper 9, the bottom surface of the communication hole 7 and the top surface of the top block 6 are flush, so that the waste is pushed by the scraper 9 and moved to the communication hole 7.

[0031] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
