DETAILED DESCRIPTION
[0034] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0035] like Figure 1-6As shown, embodiment 1, a preferred embodiment of the present invention, discloses a leather positioning punching device, which is different from the traditional punching device in that the present invention adopts an "upper pad and lower knife" setting method, which includes a punching platform 1, and the punching platform has a punching space, and a punching part 2 and a knife part 3 are arranged in the punching space along the up and down directions, wherein the punching part 2 is connected to the upper end of the punching platform 1, and the knife part 3 is connected to the lower end of the punching platform 1.
[0036] The stamping part 2 is vertically arranged and connected to the stamping platform by a piston rod 4, wherein the connection mode of the piston rod 4 is through a piston stamping system connected to the punching platform 1. The piston stamping system adopts a piston drive, specifically a driving structure of the piston rod 4 and the piston cylinder. The drive of the piston rod 4 is driven by a servo motor. The servo motor here is connected to a controller to realize opening and closing, as well as various working states. The controller is also connected to the mains.
[0037] The piston rod 4 is driven to move only in the vertical direction, and the lower end of the piston rod 4 is connected to a punch pad 5. The material hardness of the punch pad 5 is required to be above 40cr. A positioning lamp 6 is arranged in the punch pad 5, wherein the positioning lamp 6 generally adopts an infrared lamp, and its light beam is relatively concentrated. The infrared lamp is connected to the lead 11, and the lead 11 is electrically connected to the controller. The infrared lamp is started by the controller. A light hole 7 is opened at the lower end of the punch pad 5. The diameter of the light hole 7 is generally 1.0 mm, so that the infrared lamp installed inside the punch pad 5 can irradiate downward through the light hole 7.
[0038] The tool portion 3 includes a punching knife 9 connected to the punching platform, wherein the punching knife 9 is connected through a work table 8 installed on the punching platform 1, and the work table 8 is fixedly installed on the punching platform 1. The punching knife 9 is connected to the work table 8. The installation method of the punching knife 9 can be movable and can be movably connected to the work table 8 by bolts. Specifically, radially arranged threaded holes can be provided in the circumferential direction of the work table 8. By screwing the bolts inward, the punching knife 9 is positioned and locked in the current position. Bolt holes matching the bolts are opened on the circumferential side of the punching knife 9 to achieve the purpose of positioning and installation;
[0039] The punching knife 9 is set with the blade facing upward, and the punching knife 9 and the punching pad 5 are arranged relative to each other up and down, so that the light of the positioning lamp passes through the light-transmitting hole 7 and shines on the leather set on the filling knife, so that the positioning lamp 6, the light-transmitting hole 7 and the center position of the punching knife 9 are set along a straight line, ensuring that the infrared beam of the irradiation lamp can be accurately positioned and irradiated on the center position of the punching knife 9, so regardless of the thickness of the leather, accurate positioning effect can be achieved.
[0040] A vertically penetrating collection pipe 10 is opened inside the punching knife 9 and the workbench 8. The outer edge of the upper end of the punching knife 9 is a conical structure, and the top is a thin ring-shaped blade body structure. The lower end of the punching pad 5 has a groove that cooperates with the conical structure; the groove structure at the lower end of the punching pad 5 enables it to cooperate with the blade body of the punching knife 9, thereby smoothly cutting the leather. The light transmission hole 7 passes through the groove and extends to the lower end of the groove. The position of the groove is set in the middle position of the punching pad, thereby ensuring that the light transmission hole 7 can illuminate light from the light transmission hole, thereby illuminating the punching knife 9 below;
[0041] The cutting blade 9 and the working table 8 are both provided with a vertically extending collecting pipe 10, and each of the collecting pipes 10 is connected to each other to form a waste channel, which extends upward to the outside of the cutting blade and downward to the outside of the punching platform 1. Due to the annular blade shape at the upper end, the cut waste directly enters the collecting pipe 10, wherein the collecting pipe 10 is penetrated in the up and down directions, and the cut waste enters the collecting pipe 10 in the cutting blade 9. Due to the friction resistance after cutting, even if the waste does not enter the collecting pipe 10 of the working table 8 at the first time, the previous waste will be pushed downward during the next punching process, so that after passing through the collecting pipe 10 of the working table 8, it will be collected in the trash can below. The inner diameter of the collecting pipe 10 of the working table 8 can be set larger, or the collecting pipe 10 in the cutting blade 9 can be set to be narrow at the top and wide at the bottom, so that the waste can be smoothly collected after passing through the collecting pipe 10;
[0042] At the same time, in order to facilitate the punching knife 9 heads with different punching diameters, we set the connection method of the punching knife 9 to a detachable connection. The inner ring diameter of the punching knife 9 head is usually one of 2.5mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm, 5.0mm, 5.5mm, and 6.0mm, which is selected for different hole sizes.
[0043] The piston punching system and the positioning light 6 are electrically connected to the controller, which is controlled by a single chip microcomputer. The working states of the controller piston punching system and the infrared irradiation lamp are prior art and will not be described in detail here.
[0044] When this embodiment is working: after selecting the cutter head of the punching knife 9 of the corresponding diameter, it is installed on the workbench 8 by bolts. After the installation is completed, the leather to be punched is placed on the punching knife 9, and the infrared irradiation lamp is turned on by the controller. The light beam is irradiated on the leather material to be punched through the light-transmitting hole 7 to achieve precise positioning and avoid deviation. Then the piston rod 4 in the piston punching system is controlled by the controller to punch the leather downward. With the cooperation of the punching pad 5 and the punching knife 9, the punching work of the leather is realized. The waste material after punching enters the collection pipe 10 in the punching knife 9. As the punching work proceeds, the waste material is gradually concentrated in the collection pipe 10 in the punching knife 9, and then enters the trash can for concentration after passing through the collection pipe 10 in the workbench 8.
[0045] Example 2, as Figure 1-6 As shown, on the basis of the above embodiment, a controller is also included. The punching platform 1 is further connected to a first ring body 12 and a second ring body 13 which are coaxially arranged with the center position of the punching knife 9. The first ring body 12 is sleeved on the outside of the punching knife 9, and the second ring body 13 is sleeved on the outside of the punching pad 5. The two sets of ring bodies are coaxially arranged with the center of the punching knife 9 and the punching pad 5. The first ring body 12 is arranged at the bottom, and the second ring body 13 is arranged at the top. The first ring body 12 is also mounted on the workbench 8 by bolts, and its height can be adjusted by damping friction. Generally, it is not adjusted.
[0046] The lower end of the first ring body 12 is connected to a distance sensor of the second ring body 13, and the second ring body 12 is driven by a drive system installed in the punching platform 1 to move vertically, wherein the drive system adopts an electric telescopic rod 14 installed on the punching platform 1, and the end of the electric telescopic rod 14 is connected to the second ring body 13. The electric telescopic rod 14 is driven by the controller to move in the vertical direction, driving the second ring body 13 to move in the vertical direction, thereby adjusting the distance between the two groups of ring bodies, wherein the distance sensor is connected to the controller, and the distance trigger threshold is less than the distance of a finger, which can be set to 5mm. If it can drop normally during the process of 5mm distance, it means that there is no foreign matter between the ring bodies;
[0047] When this embodiment is in use, before performing the drilling operation, the controller drives the electric telescopic rod 14 and the second ring body 13 to move in the vertical direction. In the process of approaching the first ring body 12, if there is no foreign object at a position 125 mm away from the first ring body, the subsequent drilling operation is triggered by the controller to protect the operator's hands.
[0048] In summary, the embodiment of the utility model provides a leather positioning punching device, which adopts the "upper pad and lower knife" setting method. The irradiation lamp is set inside the punching pad 5, and the irradiation positioning lamp 6 is vertically irradiated and positioned. The punching position is not restricted by the thickness change of the material, and the punching can be accurately and quickly positioned, which greatly improves work efficiency and production capacity. The punching knife 9 is set with the blade facing upward, and the punched waste is collected from the collection pipe 10 into the trash can, eliminating the need for manual centralized collection and optimizing the environment around the machine. At the same time, two sets of rings are used to prevent safety hazards and avoid harming users.
[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
