Description

Technical Field

[0001] This utility model relates to the field of metal cutting technology, and in particular to an automatic loading and unloading circular metal part cutting device. Background Technology

[0002] Metal cutting is a material removal and forming method in metal forming processes. The metal cutting process is a process of interaction between the workpiece and the cutting tool. The cutting tool removes excess metal from the workpiece to be processed. Most of the time, it is used to cut long metal rods into short rods of equal distance.

[0003] In the existing technology, traditional cutting lathes require a separate operator to place long metal rods one by one on the machining platform for cutting. Since there are many metal parts, it consumes a lot of the operator's energy, resulting in a significant increase in production costs. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art: the traditional cutting lathe requires a separate operator to place long metal rods one by one on the processing platform for cutting. Since there are many metal parts, it will consume a lot of the operator's energy, resulting in a significant increase in production costs. Therefore, an automatic loading and unloading circular metal part cutting device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic loading and unloading circular metal part cutting device includes a base and a loading box. The base has a groove, and the outer wall of the loading box is fixedly connected to the inner wall of the groove.

[0007] A feeding component is installed on the base. The feeding component includes a sleeve, a support rod, a piston, and a push plate. A fixing plate is fixedly connected to the inner wall of the groove. The sleeve is fixedly connected to the fixing plate. The piston is slidably connected inside the sleeve. One end of the support rod is fixedly connected to the piston. The push plate is fixedly connected to the other end of the support rod. A second spring is fixedly connected between the piston and the inner wall of the sleeve. A feeding port is opened at the lower end of the feeding box. Two baffles are provided at the lower end of the feeding box. The two baffles are respectively arranged on both sides of the feeding port.

[0008] Preferably, the feeding component further includes an L-shaped plate and an airbag. One end of each of the two L-shaped plates is slidably connected to both ends of the base. The airbag is fixedly connected between one of the L-shaped plates and the outer surface of the base. A connecting pipe is fixedly connected between the airbag and the sleeve.

[0009] Preferably, a first spring is fixedly connected between each of the two L-shaped plates and the outer surface of the base, and the first spring is located on the upper side of the airbag.

[0010] Preferably, a mounting box is fixedly connected to the base, and sliding grooves are provided on both side walls of the mounting box. A cutter with a convex shape is slidably connected inside the mounting box, and both ends of the cutter are slidably connected in the sliding grooves by sliders.

[0011] Preferably, a hydraulic rod is fixedly connected to the mounting box, one end of the hydraulic rod is fixedly connected to the cutter, and trapezoidal blocks are fixedly connected to both ends of the cutter.

[0012] Preferably, the base has a feeding port, and a lead screw is threadedly connected to the base. One end of the lead screw is rotatably connected to a limiting plate, and the limiting plate is slidably connected to the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] As the support rod pushes the push plate to the right, it can push the metal rod on the lower side of the feed box and push the metal rod to the right end to fit against the limiting plate. Then, the hydraulic rod is driven to extend and push the cutter down to cut the metal rod. The lead screw can be rotated to drive the limiting plate to move horizontally. By adjusting the distance between the limiting plate and the cutter, the desired length of the metal rod can be obtained.

[0015] As the cutter moves downward, it can push the trapezoidal block downward. The trapezoidal block can push the L-shaped plate to move and squeeze the first spring and airbag. As the two L-shaped plates move in the center, they can clamp the metal rod to be cut to ensure the stability of the cut.

[0016] As the support rod moves horizontally back and forth, the push plate can push the metal rod that has slid down into the base and is located between the two baffles to the underside of the cutter, so that the cutter can cut the metal rod, thus achieving the effect of automatic feeding of the metal rod.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0024] Reference Figures 1-4 An automatic loading and unloading circular metal cutting device includes a base 1 and a loading box 6. The base 1 has a groove for moving metal rods. The outer wall of the loading box 6 is fixedly connected to the inner wall of the groove. The upper end of the loading box 6 is square and the lower end is an inverted isosceles trapezoid. Therefore, the metal rods in the loading box 6 will fall into the groove in sequence and be positioned between two baffles, which facilitates the push plate 3 to push the metal rods to the right. The base 1 has a loading port. A lead screw 11 is threadedly connected to the base 1. One end of the lead screw 11 is rotatably connected to a limit plate 10, which is slidably connected to the base 1.

[0025] A feeding component is installed on the base 1, which includes a sleeve 4, a support rod 17, a piston 18, and a push plate 3. A fixing plate 5 is fixedly connected to the inner wall of the groove. The sleeve 4 is fixedly connected to the fixing plate 5. The piston 18 is slidably connected inside the sleeve 4. One end of the support rod 17 is fixedly connected to the piston 18. The support rod 17 is slidably connected to the right end face of the sleeve 4 in a sealed manner. The left end of the sleeve 4 is not sealed. The push plate 3 is fixedly connected to the other end of the support rod 17. A second spring 16 is fixedly connected between the piston 18 and the inner wall of the sleeve 4. A feeding port is opened at the lower end of the feeding box 6. Two baffles are provided at the lower end of the feeding box 6. The baffles are used to limit the metal rod that falls into the groove on the base 1, so that the metal rod is in a certain position. The two baffles are horizontally positioned and parallel to the inner wall of the groove. The two baffles are respectively located on both sides of the feed port. The feeding component also includes an L-shaped plate 13 and an airbag 15. One end of each of the two L-shaped plates 13 is slidably connected to both ends of the base 1. The airbag 15 is fixedly connected between one of the L-shaped plates 13 and the outer surface of the base 1. One end of each L-shaped plate 13 is located in the groove. Therefore, when the two L-shaped plates 13 move in the center, they can clamp the metal rod in the groove. A connecting pipe 2 is fixedly connected between the airbag 15 and the sleeve 4. The connecting pipe 2 is located to the right of the piston 18. A first spring 14 is fixedly connected between each of the two L-shaped plates 13 and the outer surface of the base 1. The first spring 14 is located on the upper side of the airbag 15.

[0026] A mounting box 8 is fixedly connected to the base 1. Slide grooves are provided on both side walls of the mounting box 8. A convex-shaped cutter 9 is slidably connected inside the mounting box 8. Both ends of the cutter 9 are slidably connected to the slide grooves via sliders 19, which allows it to move vertically up and down under the limit of the sliders 19. A hydraulic rod 7 is fixedly connected to the mounting box 8. One end of the hydraulic rod 7 is fixedly connected to the cutter 9. Trapezoidal blocks 12 are fixedly connected to both ends of the cutter 9. The trapezoidal blocks 12 are right-angled trapezoids. When the trapezoidal blocks 12 move down, the lower inclined surface of the trapezoidal blocks 12 first contacts the L-shaped plate 13 and squeezes the L-shaped plate 13 to move a certain distance until the L-shaped plate 13 slides to the vertical surface of the trapezoidal blocks 12. The L-shaped plate 13 no longer squeezes. Therefore, the distance that the L-shaped plate 13 moves each time is the same, which clamps metal rods of the same diameter.

[0027] In this invention, during use, a large quantity of metal rods are first placed horizontally in the feeding box 6. The metal at the bottom will fall sequentially into the groove, driving the hydraulic rod 7 to retract and causing the cutter 9 to move upwards, as shown in the attached diagram. Figure 1As shown, at this time, the trapezoidal block 12 no longer exerts pressure on the L-shaped plate 13. Under the elastic force of the first spring 14, the L-shaped plate 13 moves away from the base 1 and resets. The movement of the L-shaped plate 13 no longer compresses the airbag 15. At this time, the second spring 16 pushes the piston 18 and the support rod 17 to move to the right. The piston 18 can squeeze the gas in the sleeve 4 back to the airbag 15 through the connecting pipe 2. As the support rod 17 pushes the push plate 3 to move to the right, it can push the metal rod on the lower side of the feed box 6 and push the metal rod to the right end to fit with the limiting plate 10. Then, the hydraulic rod 7 is driven to extend and push the cutter 9 to move down to cut the metal rod. The lead screw 11 can be rotated to drive the limiting plate 10 to move horizontally. By adjusting the distance between the limiting plate 10 and the cutter 9, the desired length of the metal rod can be obtained.

[0028] As the cutter 9 moves downward, it can push the trapezoidal block 12 downward. The trapezoidal block 12 can push the L-shaped plate 13 to move and squeeze the first spring 14 and the air bag 15. As the two L-shaped plates 13 move in the center, they can clamp the metal rod to be cut to ensure the stability of the cut. The gas in the air bag 15 flows into the sleeve 4 through the connecting pipe 2 and pushes the piston 18 and the support rod 17 in the sleeve 4 to move to the left. The push plate 3 moves to the left with the support rod 17 and resets. At this time, one of the metal rods in the feeding box 6 slides down onto the base 1 and is between the two baffles, ready for the cutter 9 to move upward. The push plate 3 pushes the metal rod to the right again and cuts it, thus completing the effect of automatic feeding of the metal rod.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
