Description

Technical Field

[0001] This utility model belongs to the technical field of punch press mold equipment, and in particular relates to a servo feeding mechanism. Background Technology

[0002] During the operation of a punch press die, scrap is often generated. A discharge mechanism is a commonly used scrap removal mechanism. Existing discharge mechanisms typically use two rotating rollers to clamp and discharge the scrap. The drive roller is usually driven by a common geared motor and a V-belt. For example, patent application number CN201820575029.6 discloses a scrap discharge device for a die, located behind the die body, used to discharge the scrap generated by the die body. This scrap discharge device includes a support, a drive roller, a driven roller, a motor, a transmission mechanism, and a lifting mechanism. The support includes a base with two upright plates on either side. A guide rail is provided on each upright plate. The drive roller is fixed between the tops of the two upright plates, and the driven roller is correspondingly located below the drive roller. The two ends of the driven roller are fixedly connected to a lifting mechanism and move up and down along the guide rail under the drive of the lifting mechanism. The motor is connected to the drive roller through the transmission mechanism.

[0003] The existing discharge mechanism has a low waste discharge speed and poor accuracy during use, so it is necessary to make improvements. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a servo feeding mechanism to improve the feeding speed and accuracy of the feeding mechanism.

[0005] In view of this, the present invention provides a servo feeding mechanism, comprising:

[0006] A frame, the frame including a base and two uprights disposed on the base;

[0007] A drive roller, which is rotatably mounted between two vertical plates;

[0008] A rubber roller, which is rotatably disposed between two vertical plates and above the drive roller;

[0009] A drive cylinder is installed at the top of the vertical plate to drive the rubber roller to move up and down.

[0010] Also includes:

[0011] A servo motor is mounted on one side of the upright plate;

[0012] The servo motor is directly connected to the drive roller via a coupling.

[0013] In this technical solution, during the use of the servo feeding mechanism, the servo motor and the active roller are directly connected through a coupling. The active roller rotates continuously during the operation of the servo motor. When waste material arrives, the driving cylinder operates, moving the rubber roller closer to the active roller, ultimately pressing down on the material. The active roller then drives the rubber roller to roll, thus achieving the purpose of feeding and discharging. The direct connection between the servo motor and the active roller effectively improves the speed and accuracy of waste material discharge. Furthermore, when there is a row of dies on a punch press, and the previous feeding mechanism cannot reach the last die, the servo feeding mechanism can be used as a feeding mechanism, both discharging waste material and feeding material. Compared to existing technologies, this invention effectively improves the feeding speed and accuracy of the feeding mechanism.

[0014] In the above technical solution, the rubber roller further includes:

[0015] The roller core is provided with a detachable rubber sleeve.

[0016] In the above technical solution, the rubber sleeve portion further includes:

[0017] The half-body has two halves, which can be combined to form a complete rubber sleeve that fits the roller core. The end of the half-body is provided with a semi-annular limiting groove that is concentrically distributed with the half-body.

[0018] A limiting ring is movably disposed at the end of the roller core and can move along the axial direction of the roller core. The inner sidewall of the limiting ring is provided with annular limiting protrusions that are concentrically distributed with the limiting ring.

[0019] The annular limiting protrusion can cooperate with the semi-annular limiting grooves on the two half-body to fix the two half-body on the roller core.

[0020] Furthermore, the above technical solution also includes:

[0021] A heat-conducting sheet is disposed in the half-body and located near the surface of the half-body; the heat-conducting sheet has a plurality of sheets and is evenly spaced along the circumference of the half-body.

[0022] A heat-conducting strip is disposed in the half-body and located inside the heat-conducting sheet, and several heat-conducting strips are provided corresponding to the heat-conducting sheet;

[0023] A heat sink is disposed at the end of the half-sleeve.

[0024] The heat-conducting strip is connected to the heat-conducting sheet, and both the heat-conducting sheet and the heat-conducting strip extend along the length of the half-body. The heat sink is connected to the heat-conducting strip.

[0025] Furthermore, the above technical solution also includes:

[0026] A heat insulation layer is disposed on the surface of the roller core.

[0027] The beneficial effects of this utility model are:

[0028] 1. By directly connecting the servo motor to the drive roller, the discharge speed and accuracy of waste material are effectively improved;

[0029] 2. The rubber sleeve design facilitates the maintenance of the rubber roller and improves work efficiency;

[0030] 3. The heat dissipation effect of the rubber roller is improved by setting heat-conducting sheets, heat-conducting strips and heat dissipation rods, thereby ensuring that the rubber roller will not stick to the material due to overheating and improving the stability of material discharge.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0041] Example 1:

[0042] This application provides a servo feeding mechanism, including: a frame 1, the frame 1 including a base and two vertical plates disposed on the base; an active roller 2, the active roller 2 being rotatably disposed between the two vertical plates; a rubber roller 3, the rubber roller 3 being rotatably disposed between the two vertical plates and located above the active roller 2; and a drive cylinder 4, the drive cylinder 4 being disposed at the top of the vertical plates for driving the rubber roller 3 to move up and down.

[0043] It also includes: servo motor 5, which is located on one side of the upright plate;

[0044] The servo motor 5 is directly connected to the drive roller 2 via the coupling 6.

[0045] Moreover, the frame 1 is a conventional structure, and a top plate can be installed on the top of the two upright plates. Conventional guide structures such as guide rail sliders are installed on the inner side walls of the two upright plates. The two ends of the rubber roller 3 are movably connected to the upright plates through the guide structure. For example, the two ends of the rubber roller 3 are respectively rotatably connected to the slider, and the driving end of the drive cylinder 4 is connected to the slider.

[0046] In this embodiment, during the use of the servo feeding mechanism, the servo motor 5 and the active roller 2 are directly connected through the coupling 6. During the operation of the servo motor 5, the active roller 2 rotates continuously. When waste material arrives, the drive cylinder 4 works to move the rubber roller 3 and bring it close to the active roller 2, ultimately pressing down the material. The active roller 2 drives the rubber roller 3 to roll, thereby achieving the purpose of feeding material. The direct connection between the servo motor 5 and the active roller 2 effectively improves the discharge speed and accuracy of waste material. When there is a row of molds on a punch press and the previous feeding mechanism cannot reach the last mold, the servo feeding mechanism can be used as a feeding mechanism, which can both discharge waste material and achieve feeding. Compared with the prior art, this utility model can effectively improve the feeding speed and accuracy of the feeding mechanism.

[0047] Example 2:

[0048] This embodiment provides a servo feeding mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the rubber roller 3 further includes a roller core 30, on which a rubber sleeve portion 31 is detachably provided.

[0049] The sleeve part 31 also includes: a half-sleeve 310, which has two half-sleeves 310. The two half-sleeves 310 can be combined to form a complete sleeve that fits the roller core 30. The end of the half-sleeve 310 is provided with a semi-annular limiting groove 311 that is concentrically distributed with the half-sleeve 310; and a limiting ring 312, which is movably disposed at the end of the roller core 30 and can move along the axial direction of the roller core 30. The inner sidewall of the limiting ring 312 is provided with annular limiting protrusions 313 that are concentrically distributed with the limiting ring 312.

[0050] The annular limiting protrusion 313 can cooperate with the semi-annular limiting groove 311 on the two half-body 310 to fix the two half-body 310 on the roller core 30.

[0051] Moreover, the limiting ring 312 can be movably mounted on the roller core 30 in a conventional manner, such as having an external thread at the end of the roller core 30 and an internal thread that mates with the external thread on the circumferential inner wall of the limiting ring 312.

[0052] In this embodiment, when the rubber roller 3 wears out during use, the limiting ring 312 is moved, causing the annular limiting protrusion 313 to separate from the semi-annular limiting groove 311 on the half-sleeve 310, thereby releasing the limiting fixation of the two half-sleeves 310. Then, the two half-sleeves 310 are removed from the roller core 30 and replaced with new half-sleeves 310. After the two new half-sleeves 310 are assembled and installed on the roller core 30, the limiting ring 312 is moved again, and the limiting ring 312 moves closer to the end of the half-sleeve 310. At this time, the annular limiting protrusion 313 is inserted into the semi-annular limiting groove 311. Finally, the two half-sleeves 310 are limited and fixed on the roller core 30 to form a rubber sleeve. Compared with the prior art, this utility model can effectively facilitate the maintenance of the rubber roller 3 and improve work efficiency.

[0053] Example 3:

[0054] This embodiment provides a servo feeding mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including: a heat-conducting sheet 7, which is disposed in the half-body 310 and located near the surface of the half-body 310, and has a plurality of heat-conducting sheets 7 evenly spaced along the circumference of the half-body 310; a heat-conducting strip 8, which is disposed in the half-body 310 and located inside the heat-conducting sheet 7, and has a plurality of heat-conducting strips 8 corresponding to the heat-conducting sheet 7; and a heat dissipation rod 9, which is disposed at the end of the half-body 310.

[0055] Among them, the heat-conducting strip 8 is connected to the heat-conducting plate 7, and both the heat-conducting plate 7 and the heat-conducting strip 8 extend along the length of the half-body 310. The heat sink 9 is connected to the heat-conducting strip 8.

[0056] It also includes: a heat insulation layer 10, which is disposed on the surface of the roller core 30.

[0057] In this embodiment, during operation, the heat generated on the surface of the rubber roller 3 can be quickly transferred to the heat-conducting strip 8 through the heat-conducting sheet 7. After absorbing the heat, the heat-conducting strip 8 can effectively transfer the heat to the heat dissipation rod 9. As the rubber roller 3 rotates continuously, the heat dissipation rod 9 can efficiently exchange heat with the air, thereby effectively dissipating the heat generated on the rubber roller 3 into the air and preventing the rubber roller 3 from overheating. This ensures that the rubber roller 3 will not stick to the material due to overheating, improving the stability of material discharge. At the same time, the heat insulation layer 10 can effectively prevent heat from being transferred to the roller core 30, reducing the possibility of damage to the roller core 30 due to overheating.

[0058] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
