Description

Technical Field

[0001] The utility model relates to the technical field of CNC bending machines, in particular to a feeding device for a CNC metal bar bending machine. Background Art

[0002] Metal bar CNC bending machine is a mechanical equipment specially used for bending metal bars (such as steel bars, aluminum bars, etc.). After the metal bars are bent, a feeding device is required to remove them from the bending machine and store them.

[0003] The common unloading device of the metal bar bending machine is to simply place a unloading box at the lower end of the bending machine. After the bending work is completed, the bent metal bars fall directly into the unloading box for storage to facilitate subsequent work. However, in this method, since the unloading box is fixed, the metal bars will fall in an area of ​​the unloading box. After receiving a certain number of metal bars, the unloading box needs to be manually adjusted to evenly receive the metal bars, which is time-consuming and labor-intensive.

[0004] To this end, we proposed a feeding device for a metal rod CNC bending machine that can automatically and evenly feed the materials to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a material unloading device for a metal rod CNC bending machine, which can make the bent metal rods evenly fall into the inside of a material unloading box through a parallel sliding material receiving mechanism, thereby achieving the effect of saving time and labor.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a material unloading device for a metal bar CNC bending machine, comprising a material unloading box, and also comprising a material receiving mechanism that slides parallel to the upper end of the material unloading box, a driving groove is symmetrically opened at the upper end of the inner side surface of the material unloading box, a motor is installed on the rear end surface of the material unloading box, and a threaded rod and a moving block are arranged inside the driving groove;

[0007] Slide grooves are provided on both sides of the front end surface of the material receiving mechanism, and a slider is slidably connected inside the slide groove. A fixed rod is fixedly connected to the middle of the front end of the material receiving mechanism, and a material receiving rod is fixedly connected to the front end of the slider. The material receiving rod is slidably connected to the front surface of the material receiving mechanism through the slider and the slide groove, and the fixed rod and the material receiving rod are inclined.

[0008] Preferably, a universal wheel is installed on the lower surface of the material discharge box, a push rod is fixedly installed on the rear end of the material discharge box, and a sponge pad is provided on the inner bottom surface of the material discharge box.

[0009] Preferably, the output end of the motor penetrates into the interior of the driving groove and is transmission-connected to the threaded rod, the outer surface of the threaded rod is threadedly connected to the moving block, and the side surface of the moving block is fixedly connected to the side surface of the material receiving mechanism.

[0010] Preferably, a reinforcing frame is fixedly connected between the lower end of the fixed rod and the front end of the material receiving mechanism. Adjusting rods are fixedly connected to both sides of the fixed rod, and the material receiving rod is slidably connected to the adjusting rods.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] (1) For the blanking device of the numerical control bending machine for metal rods of the present utility model, the inclined material receiving rod and the fixed rod will correspond to the blanking position of the bending machine. When the rod is bent and falls, it will land on the surfaces of the fixed rod and the material receiving rod and then slide into the interior of the blanking box. By setting the inclined fixed rod and material receiving rod for material receiving, a certain buffer space can be generated, avoiding damage to the metal rod caused by knocking when the metal rod directly falls into the interior of the blanking box.

[0013] (2) For the blanking device of the numerical control bending machine for metal rods of the present utility model, as Figure 1 shown, at the beginning, the metal rods will concentrate on the front end position of the blanking box. After a certain amount of metal rods accumulate at the front end position of the blanking box, the motor can be driven. The motor drives the material receiving mechanism, the fixed rod, and the material receiving rod to move forward a little through the threaded rod and the moving block, so that the blanking area can be changed, thereby achieving the effect of automatic and uniform material receiving, avoiding manual participation, saving time and effort, and thus increasing the overall applicability.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , a blanking device for a numerically controlled bending machine of a metal rod, including a blanking box 1, and further including a material receiving mechanism 2 that slides parallel to the upper end of the blanking box 1. Symmetrically arranged driving grooves 13 are provided at the upper end of the inner side surface of the blanking box 1. A motor 131 is installed on the rear surface of the blanking box 1. A threaded rod 132 and a moving block 133 are provided inside the driving groove 13. Sliding grooves 21 are symmetrically opened on both sides of the front surface of the material receiving mechanism 2. A slider 211 is slidably connected inside the sliding groove 21. A fixed rod 22 is fixedly connected to the middle of the front end of the material receiving mechanism 2. The front end of the slider 211 is fixedly connected to a material receiving rod 24. The material receiving rod 24 is slidably connected to the front surface of the material receiving mechanism 2 through the slider 211 and the sliding groove 21. The fixed rod 22 and the material receiving rod 24 are inclined. When in use, when the whole is located below the blanking position of the bending machine, the inclined material receiving rod 24 and the fixed rod 22 will correspond to the blanking position of the bending machine. When the rod is bent and falls, it will fall onto the surfaces of the fixed rod 22 and the material receiving rod 24 and then slide into the inside of the blanking box 1. By setting the inclined fixed rod 22 and the material receiving rod 24 for receiving materials, a certain buffer space can be generated to prevent the metal rod from directly falling into the inside of the blanking box 1 and being damaged due to collision. As Figure 1 shown, at the beginning, the metal rods will be concentrated on the front end position of the blanking box 1. After a certain amount of metal rods are accumulated at the front end position of the blanking box 1, the motor 131 can be driven. The motor 131 drives the material receiving mechanism 2, the fixed rod 22, and the material receiving rod 24 to move forward a little through the threaded rod 132 and the moving block 133, so that the blanking area can be changed, thereby achieving the effect of automatic and uniform material receiving.

[0021] Furthermore, universal wheels 11 are installed on the lower surface of the blanking box 1, a hand push rod 12 is fixedly installed at the rear end of the blanking box 1, and a sponge pad 14 is provided on the bottom surface inside the blanking box 1. When in use, by setting the universal wheels 11 and the hand push rod 12, it is convenient for the staff to move the blanking box 1 to the lower end of the bending machine and subsequent transportation work. By setting the sponge pad 14, a certain degree of protection can be provided for the falling metal rods.

[0022] Furthermore, the output end of the motor 131 penetrates into the interior of the driving groove 13 and is in transmission connection with the threaded rod 132. The outer surface of the threaded rod 132 is threadedly connected to the moving block 133. The side surface of the moving block 133 is fixedly connected to the side surface of the material receiving mechanism 2. During use, the motor 131 is a high-precision DC motor. By driving the motor 131, the threaded rod 132 inside the driving groove 13 can be driven to rotate, thereby driving the moving block 133 threadedly connected thereto to move back and forth. When the moving block 133 moves, it can drive the material receiving mechanism 2 to accurately move back and forth reciprocally.

[0023] Furthermore, a reinforcing frame 221 is fixedly connected between the lower end of the fixed rod 22 and the front end of the material receiving mechanism 2. Adjusting rods 23 are fixedly connected to both sides of the fixed rod 22. The material receiving rod 24 is slidably connected to the adjusting rods 23. During use, by providing the reinforcing frame 221, the stability of the fixed rod 22 can be further improved. Since the materials are received one by one during the material receiving operation, the stability of the fixed rod 22 and the material receiving rod 24 can be ensured. The adjusting rods 23 can further improve the stability of the material receiving rod 24.

[0024] Working principle: For the blanking device used in the numerically controlled bending machine for metal bars of the present invention, during use, first, after the metal bar is bent, it will fall on the surfaces of the inclined fixed rod 22 and the material receiving rod 24, and then slide into the interior of the blanking box 1. Since the fixed rod 22 and the material receiving rod 24 are inclined, a certain buffer space can be generated to prevent the metal bar from being damaged due to collision when directly falling into the interior of the blanking box 1. When a certain amount of metal bars accumulates at the front end position of the blanking box 1, the motor 131 can be driven. The motor 131 drives the threaded rod 132 to rotate, and then drives the material receiving mechanism 2, the fixed rod 22, and the material receiving rod 24 to move forward a little through the moving block 133, so as to change the blanking area and achieve the effect of automatic and uniform material receiving. A sponge pad 14 is provided on the bottom surface inside the blanking box 1, which can further protect the falling metal bars to a certain extent, thus enriching the overall function and increasing the overall applicability.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
