Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding of punching machines, in particular to an automatic feeding device for a punching machine. Background Art

[0002] A punch press is a stamping press. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to produce products that cannot be produced by mechanical processing through various mold applications. Therefore, its use is becoming more and more extensive. Stamping production is mainly for sheet metal. Through the mold, blanking, punching, forming, drawing, trimming, fine blanking, shaping, riveting and extrusion can be made, which are widely used in various fields.

[0003] After searching, the Chinese patent application No. 202322229612.5 discloses an automatic feeding device for a punch press. The patent relates to the field of punch press feeding technology and proposes an automatic feeding device for a punch press, including: a punch press, a storage tank provided at the top of the punch press, and a cylinder is fixedly connected to the inner bottom wall of the storage tank. The patent can realize that the stacked materials to be processed are placed in the storage tank and located above the push, and the materials are pushed upward by the cylinder to expose the materials from the storage tank, and then the second electric telescopic rod in the structure is pushed to push the exposed materials into the slot, and the punching structure is pressed down to process the materials. After the punching is completed, the waste materials are discharged from the separation structure, and the workbench is pushed upward to move the processed materials upward and exposed on the punch press. When the next feeding is performed, the processed materials will be pushed out, so that the processed waste materials and processed materials can be separated, reducing the manpower for subsequent manual sorting and increasing its degree of automation.

[0004] Although the above patent can separate the processed waste and processed materials, reduce the manpower for subsequent manual sorting, and increase its degree of automation, in actual application, the patent uses cylinders, electric telescopic rods and other structures to realize automatic feeding automation, which greatly increases production costs. At the same time, the subsequent maintenance costs are also correspondingly increased, so that expensive equipment will increase the financial burden of small and medium-sized enterprises. Especially for start-up companies, if too high mechanical equipment is required, it will increase the company's expenses and reduce the possibility of expansion and development of the company. In addition, the equipment cost will directly compress the company's profit margin, making it difficult for the company to continue to create more profits and value, which is not conducive to the development of small and medium-sized enterprises.

[0005] Therefore, it is necessary to modify the automatic feeding device in the above patent to effectively prevent the use of cylinders, electric telescopic rods and other structures to realize automatic feeding automation, which greatly increases production costs. At the same time, the subsequent maintenance costs are also correspondingly increased, making the expensive equipment increase the financial burden of small and medium-sized enterprises.

[0023] refer to Figure 4 The top of the sliding opening 7 is symmetrically fixedly connected with a limit strip 16 , and the bottom of the limit strip 16 is fixedly connected with a damping strip 17 .

[0024] As a technical optimization solution of the utility model, by setting the limit strip 16 and the damping strip 17, the damping effect on the raw material can be improved, so that it cannot slide by itself, thereby improving the accuracy of stamping the raw material.

[0025] refer to Figure 1 , Figure 2 and Figure 3 A tilting block 18 is fixedly connected to one side of the feeding strip 5 , and a limiting strip 19 is symmetrically fixedly connected to the top of the discharge port 6 .

[0026] As a technical optimization solution of the utility model, by providing the tilting block 18 and the limiting strip 19, it is convenient to separate and guide the processed waste materials to prevent them from flying out.

[0027] refer to Figure 1 and Figure 2A waste box 20 is provided on one side of the base 1, and the waste box 20 is used in conjunction with the tilting block 18. A collecting box 21 is provided at the bottom of the base 1, and the collecting box 21 is used in conjunction with the discharge port 6.

[0028] As a technical optimization solution of the present invention, by providing the waste box 20 and the collection box 21, the processed waste and finished products can be classified and collected in a centralized manner so as to be subsequently processed in a unified manner.

[0029] refer to Figure 1 An observation port 22 is provided on one side of the feeding frame 8 .

[0030] As a technical optimization solution of the present invention, the setting of the observation port 22 makes it convenient for the staff to observe the raw materials in the feeding frame 8 and replenish them in time.

[0031] refer to Figure 3 The side of the feeding block 15 with the maximum displacement distance is located at the same horizontal plane as the inner wall of the lifting port 9.

[0032] As a technical optimization solution of the utility model, by arranging the side of the feeding block 15 with the maximum displacement distance to be on the same horizontal plane as the inner wall of the lifting port 9, the feeding block 15 is prevented from escaping from the sliding port 7 when moving outward, thereby improving the stability of the device during operation.

[0033] The working principle and use process of the utility model are as follows: when the staff uses the automatic feeding device of the punch press, first the device is connected to an external power supply, and then the raw material is placed in the lifting port 9, and then the servo motor 10 is started to drive the rotating rod 11 to rotate. At this time, the raw material falls along the lifting port 9 to the inside of the sliding port 7, and is located in front of the feeding block 15. At this time, since the feeding block 15 can only slide in the sliding port 7, the movement trajectory of the rotating rod 11 can push the transmission rod 13 to perform linear reciprocating motion, and then the feeding block 15 can perform reciprocating linear motion, that is, as the feeding block 15 is pushed forward, the raw material can be pushed into the bottom of the punching block 4. When the feeding block When 15 moves backward to the maximum position, the next raw material falls to the front of the feeding block 15 again due to gravity, waiting to be pushed. At this time, the cooperation of the limit bar 16 and the damping bar 17 can increase the resistance of the raw material in the slide 7, thereby avoiding excessive sliding due to the inertia produced during pushing, thereby improving the accuracy during stamping. Then the hydraulic telescopic rod 3 is started to drive the stamping block 4 to stamp the raw material, and the stamped product falls into the collection box 21 through the discharge port 6. Then the feeding block 15 pushes the next raw material under the stamping block 4, so that the new raw material presses against the processed waste, and pushes it completely out of the slide 7, and moves it to the tilting block 18 to slide into the waste box 20.
