Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to an automatic feeding hydraulic cutting machine. Background Art

[0002] Hydraulic cutting machine is an indispensable equipment in some light industries. It is a machine that uses the force of machine movement to pressurize the cutting die to punch non-metallic materials. It is mainly used for punching and cutting non-metallic materials such as foam materials, cardboard, textiles, plastic materials, packaging materials, flooring materials, cork, etc. through the cutting die with the help of the punching pressure generated by the machine.

[0003] After the cutting machine surface is automatically fed by the feeding push plate, the material moves on the surface of the cutting machine shell. Due to the lack of restrictions on the material during movement, when the material is pushed to the cutting position on the surface of the cutting machine shell by the feeding push plate, in order to avoid position deviation of the material during the cutting process, personnel need to use other tools to correct the position of the material, thereby increasing the work intensity of the personnel and reducing their work efficiency.

[0004] For example, an automatic feeding hydraulic cutting machine disclosed in Chinese patent CN218614364U adopts a limit rod, a slide, a support rod and a slider as well as an electric push rod to realize rapid correction of the material position. After the material is pushed to the cutting position on the front of the cutting machine housing, the electric push rod drives the top support rod to move to both sides of the material. The two sets of electric push rods advance the same distance until the limit rod at the top of the support rod contacts both sides of the material, thereby avoiding the need for manual correction of the material with the help of other tools, reducing the work intensity of the personnel and thus improving the work efficiency of the personnel.

[0005] However, the hydraulic shearing machine feeds materials through a feeding push rod, so only materials shorter than the length of the hydraulic shearing machine can be placed on it and then pushed toward the cutting tool for cutting. Therefore, the feeding structure on the hydraulic shearing machine has limitations and cannot cut plate-shaped materials that are too long and larger than the hydraulic shearing machine.

[0006] For this reason, we urgently need to provide an automatic feeding hydraulic cutting machine that can feed materials of different lengths. Utility Model Content

[0015] A further improvement is that a scale line is opened on the upper side of the extension rod, and the right side of the baffle abuts against the right side of the material to be cut, so that the distance between the baffle and the cutting tool is adjusted according to the required cutting length of the material, so that the material is transported to the right until it contacts the baffle and is cut, so that the material can be continuously cut to the required length, so that the material can be cut into the same required length more quickly.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 7 The utility model provides a technical solution: an automatic feeding hydraulic cutting machine, comprising a workbench 1 and a support rod 2, the support rod 2 is fixedly connected to the four corners of the lower side of the workbench 1, so that the workbench 1 can be supported more firmly, a support frame 3 is fixedly connected to the upper left side of the workbench 1, and the upper end of the workbench 1 is connected to a cutting mechanism.

[0029] The cutting mechanism includes a first circular shaft 401, which is rotatably connected to the right side of the inner part of the workbench 1 at an equidistant distance. A rotating roller 402 is fixedly connected to the outer side of the first circular shaft 401. The inner part of the workbench 1 is rotatably connected to the left and right ends below the support frame 3. The outer side of the second circular shaft 403 is fixedly connected to a transmission shaft 404. A motor 405 is installed on the rear side of the workbench 1. A belt shaft 406 is fixedly connected to the outer side of the front end of the second circular shaft 403. A belt 407 is sleeved on the outer side of the belt shaft 406. The upper end of the workbench 1 is located below the support frame 3 and is fixedly connected to a base 408. A hydraulic cylinder 409 is installed on the upper side of the support frame 3, and the lower end of the hydraulic cylinder 409 is fixedly connected to a connecting plate 410. A cutting tool 411 is installed on the lower side of the connecting plate 410, and an inverted U-shaped frame 412 is fixedly connected to the upper side of the workbench 1 above the first circular shaft 401 and the second circular shaft 403. The top inner side of the inverted U-shaped frame 412 is fixedly connected to a first spring 413, and the lower end of the first spring 413 is fixedly connected to a slider 414. The inner rotation of the slider 414 is connected to the third circular shaft 415, and the outer side of the third circular shaft 415 is fixedly connected to a pressure roller 416. The slider 414 is slidably connected to the inner side of the inverted U-shaped frame 412, and the front and rear sides of the pressure roller 416 are slidably connected to the adjacent side of the inverted U-shaped frame 412 at the front and rear ends, so that when the pressure roller 416 is squeezed, the slider 414 can slide along the inner side of the inverted U-shaped frame 412.

[0030] The front end of the output shaft of the motor 405 is fixedly connected to the rear end of the second circular shaft 403 on the right side of the base 408. The outer sides of the rotating roller 402, the transmission shaft 404, and the pressure roller 416 abut against the outer end of the material to be cut. Thus, after one end of the material is pushed from between the right-end rotating roller 402 and the pressure roller 416 to between the right-end transmission shaft 404 and the pressure roller 416 of the base 408, the motor 405 is started again, and its output shaft rotates to drive the right-end second circular shaft 403. Through the transmission of the front-end belt 407, the left-end second circular shaft 403 rotates together, and thus the two transmission shafts 404 rotate together, continuously transmitting the material on the rotating roller 402 and the transmission shaft 404 to the left, thereby continuously conveying long lengths of material.

[0031] The left and right ends of the lower side of the first circular shaft 401 are fixedly connected with a first rectangular frame 501, the inner top end of the first rectangular frame 501 is fixedly connected with a second spring 502, and the lower end of the second spring 502 is fixedly connected with a pressure plate 503. The inner side of the first rectangular frame 501 is slidably connected to the outer side of the pressure plate 503, so that when the hydraulic cylinder 409 is started to move the cutting tool 411 at the lower end downward to cut the material, the lower end of the second spring 502 will first contact the upper side of the material, so that the material will be pressed by the pressure plate 503 when being cut, thereby ensuring the stability of the material when being cut.

[0032] A groove is provided inside the base 408, and a bearing 601 is fixedly connected to the inner side of the groove, and a first threaded rod 602 is fixedly connected to the inner side of the bearing 601, and a toggle rod 603 is fixedly connected to the end of the first threaded rod 602 away from the bearing 601, and an adjusting block 604 is threadedly connected to the outer side of the first threaded rod 602, and a second rectangular frame 605 is fixedly connected to the upper side of the adjusting block 604, and a third spring 606 is fixedly connected to the inner bottom end of the second rectangular frame 605, and the upper end of the third spring 606 is fixedly connected to the limiting plate 607, and the first threaded rods 602 at the left and right ends of the toggle rod 603 are symmetrical, and the outer side of the adjusting block 604 is slidably connected to the inner bottom end of the groove, so that when the toggle rod 603 is rotated, the adjusting blocks 604 at the outer ends of the first threaded rods 602 at the left and right ends can be driven to move relative to each other.

[0033] The inner side of the second rectangular frame 605 is slidably connected to the outer side of the limiting plate 607, and the adjacent sides of the limiting plates 607 at the left and right ends in the groove are slidably connected to the front and back sides of the material, so that when the material is transported, it can only slide between the limiting plates 607 at the left and right ends, preventing the material from being offset during movement and causing offset during cutting.

[0034] The front and rear ends of the left side of the workbench 1 are fixedly connected to the extension rod 701, and the outer side of the extension rod 701 is slidably connected to the moving block 702, the upper end of the moving block 702 is connected to the second threaded rod 703, the upper end of the second threaded rod 703 is fixedly connected to the rotating handle 704, and the outer side of the moving block 702 is fixedly connected to the baffle 705. A threaded hole is provided on the inner upper end of the moving block 702, and the outer side of the second threaded rod 703 is threadedly connected to the inner side of the threaded hole, and the lower end of the second threaded rod 703 abuts against the upper side of the extension rod 701, so that the moving block 702 slides along the outer side of the extension rod 701, and then the rotating handle 704 is turned so that the second threaded rod 703 is located in the threaded hole and rotates while moving downward, so that when the lower end of the second threaded rod 703 abuts against the upper side of the extension rod 701, the moving block 702 can be fixed to the outer end of the extension rod 701, so that the baffle 705 can be moved and then re-fixed.

[0035] There is a scale line on the upper side of the extension rod 701, and the right side of the baffle 705 abuts against the right side of the material to be cut. Therefore, the distance between the baffle 705 and the cutting tool 411 is adjusted according to the length of the material to be cut, so that the material is transported to the right and cut after contacting the baffle 705. The material can be continuously cut to the required length, so that the material can be cut into the same required length more quickly.

[0036] Working principle: When cutting the material, first move the moving block 702 so that the distance between the baffle 705 and the cutting tool 411 is the length of all the materials to be cut, then re-fix the baffle 705, then start the motor 405 to rotate the transmission shaft 404, and then push one end of the material to be cut from between the rotating roller 402 and the pressure roller 416 at the right end until it moves to between the rotating roller 402 and the pressure roller 416 on the right side of the base 408. The rotated transmission shaft 404 is transported to the left and passes between the limit plates 607 above the base 408 until the left end of the material contacts the right side of the baffle 705. Then start the hydraulic cylinder 409, and its output shaft moves downward to drive the cutting tool 411 to move downward to cut the material on the base 408, and the cut material automatically falls from between the extension rods 701 and is collected.
