Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cutting tool technology, and specifically relates to a fixed-length cutting tool for a fence-type metal plate. Background Technology
[0002] Fence-type metal panels, such as Figure 7 As shown, its main body is a flat plate 1001, on which are distributed equidistant fence panels 1002. The top of the fence panel is the fence top 1004, and the top surface of the flat plate between two fence panels is the gap bottom 1003.
[0003] Fence-type metal panels have many applications in daily life, such as heat dissipation panels (such as the heat dissipation panel with publication number CN305385980S), mounting panels, and decorative panels.
[0004] However, because the thickness at the top 1004 of the fence is relatively large, when cutting the fence-type metal plate to a fixed length, the cutting tool is generally used to cut at the weaker gap bottom 1003 on the fence-type metal plate. The advantage of doing so is that it can reduce tool wear and save cutting time, and also preserve the integrity of the fence plate 1002. However, the existing cutting equipment requires manual searching for the gap bottom 1003 before cutting, which wastes not only manpower but also production time. Therefore, the existing technology needs a fence-type metal plate cutting tool that can automatically find the gap bottom and cut. Utility Model Content
[0005] The purpose of this invention is to provide a fixed-length cutting tool for fence-type metal plates, so as to solve the technical problem in the background art that manual cutting of gaps wastes manpower and production time.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A fixed-length cutting tool for a fence-type metal plate includes: a servo slide, a translation bracket, and a telescopic cylinder; a plate-shaped sliding plate is fixed to the moving end of the servo slide, a vertical translation bracket is fixed to the sliding plate, an L-shaped beam is fixed to the translation bracket, the top of the beam is horizontally rod-shaped, and a telescopic cylinder is rotatably fitted to the end of the beam away from the translation bracket; a gap-finding mechanism is located at the lower end of the telescopic cylinder; a return spring is directly or indirectly connected to the translation bracket on the side of the telescopic cylinder; the main body of the gap-finding mechanism is a rod-shaped sliding rod, the moving end of the telescopic cylinder is hollow, and the sliding rod is slidably embedded therein; a wheel frame is fixed to the bottom of the sliding rod, and at least one set of gap-finding wheels is rotatably fitted to the bottom of the wheel frame; a spring seat is provided on the opposite surface of the moving end of the telescopic cylinder and the wheel frame, forming a first spring seat and a second spring seat respectively; the first spring seat and the second spring seat are connected by a compression spring; a laser cutting head is fixed to the side wall of the fixed end of the telescopic cylinder by a cutting head bracket.
[0008] Furthermore, to prevent the guide wheel from entering the gap between the fence panels under the holding force, a vibration motor is fixed in the wheel frame.
[0009] Furthermore: In order to facilitate the movement of the fence-shaped metal plate to the laser cutting head for cutting, the servo slide is equipped with a support frame at the bottom. A conveyor belt is installed in the space below the servo slide after the support frame is raised. The conveying direction of the conveyor belt is perpendicular to the movement direction of the servo slide (the conveyor belt is a conventional conveyor belt, so its specific structure is omitted and simplified in the figure).
[0010] Furthermore, in order to enhance the structural strength of the beam, the beam is reinforced by an inclined beam between it and the translation support, and the return spring is indirectly fixed to the translation support by being fixed to the inclined beam.
[0011] Furthermore, to avoid friction between the side of the gap-finding wheel and the fence-shaped metal plate during laser cutting, the outer circumferential surface of the gap-finding wheel is provided with circumferentially distributed balls.
[0012] Furthermore, to avoid the risk of the laser cutting head colliding with the fence-type metal plate before cutting the workpiece, the distance between the bottom of the laser cutting head and the bottom of the gap-finding wheel is between -cm.
[0013] Furthermore, in order to ensure that the telescopic cylinder can fall vertically in the initial state, the length of the return spring must satisfy the following condition: when the return spring is not under force, the telescopic cylinder connected to it is in a vertical state.
[0014] Furthermore, the central axis of the laser cutting head and the central axis of the gap-finding wheel are located in the same plane.
[0015] In summary, this utility model has the following beneficial effects:
[0016] It can autonomously find the bottom of the gap for cutting: Through the establishment of a gap-finding mechanism and a vibrating motor, the gap-finding wheel on the gap-finding mechanism at the lower end of the telescopic cylinder is blocked. With the assistance of the vibrating motor, the gap-finding wheel will roll and enter between two sets of fence plates, rolling towards the bottom of the gap. At this time, the horizontal position of the gap-finding wheel changes slightly, which in turn causes a slight change in the horizontal position of the lower end of the gap-finding mechanism, and then a slight change in the horizontal position of the lower end of the telescopic cylinder connected to the gap-finding mechanism. In order to adapt to this change, the telescopic cylinder will deflect around the end of the beam. The return spring is stretched or compressed to store elastic potential energy. Because the central axis of the laser cutting head and the central axis of the gap-finding wheel are located on the same plane, the gap-finding wheel that rolls down between the two sets of fence plates will guide the laser cutting head to also enter between the two sets of fence plates. At this time, the vibration motor is turned off, the laser cutting head is started, and the servo slide is started. The servo slide drives the sliding plate to move, and the sliding plate drives the translation bracket on it to move accordingly. The telescopic cylinder, cutting head bracket, and laser cutting head connected to the translation bracket move accordingly to cut the bottom of the gap in the fence-type metal plate, thus completing the cutting operation of finding the bottom of the gap by itself.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] Please see Figures 1-7 The present invention provides the following technical solution:
[0027] A fixed-length cutting tool for a fence-type metal plate includes: a servo slide 1, a translation bracket 2, and a telescopic cylinder 4; a plate-shaped sliding plate 101 is fixed on the moving end of the servo slide 1, a vertical translation bracket 2 is fixed on the sliding plate 101, an L-shaped beam 3 is fixed on the translation bracket 2, the top of the beam 3 is horizontally rod-shaped, and a telescopic cylinder 4 is rotatably fitted to the end of the beam 3 away from the translation bracket 2; the moving end of the telescopic cylinder 4 is positioned below and connected to a gap-finding mechanism 8; a return spring 6 is used on the side of the telescopic cylinder 4 to directly or indirectly translate the translation bracket. 2. The main body of the gap-finding mechanism 8 is a rod-shaped sliding rod 81. The moving end of the telescopic cylinder 4 is hollow, and the sliding rod 81 is slidably embedded in it. A wheel frame 82 is fixed at the bottom of the sliding rod 81. At least one set of gap-finding wheels 84 are rotatably fitted at the bottom of the wheel frame 82. A spring seat is provided on the opposite surface of the moving end of the telescopic cylinder 4 and the wheel frame 82, forming a first spring seat 41 and a second spring seat 85, respectively. The first spring seat 41 and the second spring seat 85 are connected by a compression spring 83. A laser cutting head 7 is fixed to the side wall of the fixed end of the telescopic cylinder 4 by a cutting head bracket 71.
[0028] A vibration motor 9 is fixed in the wheel frame 82.
[0029] The servo slide 1 is raised at the bottom by a support leg 102. After the support leg 102 is raised, a conveyor belt 11 is set in the space below the servo slide 1. The conveying direction of the conveyor belt 11 is perpendicular to the movement direction of the servo slide 1 (the conveyor belt 11 is a conventional conveyor belt, so its specific structure is omitted and simplified in the figure).
[0030] The beam 3 and the translation support 2 are reinforced by an inclined beam 5, and the return spring 6 is indirectly fixed to the translation support 2 by being fixed to the inclined beam 5.
[0031] The outer circumferential surface of the gap-finding wheel 84 is provided with circumferentially distributed balls 86.
[0032] The distance between the bottom of the laser cutting head 7 and the bottom of the gap-finding wheel 84 is between 1 and 3 cm.
[0033] The length of the return spring 6 must satisfy the following condition: when the return spring 6 is not under force, the telescopic cylinder 4 connected to it is in a vertical state.
[0034] The central axis of the laser cutting head 7 and the central axis of the gap-finding wheel 84 are located in the same plane.
[0035] Brief description of usage:
[0036] In use, place the fence-shaped metal plate 10 to be cut on the conveyor belt 11 in the position shown in the figure, power on the conveyor belt 11 to make it work, and the conveyor belt 11 will transport the fence-shaped metal plate 10 to below the laser cutting head 7. At this time, drive the telescopic cylinder 4 to extend, and at the same time power on the vibration motor 9 to make it work.
[0037] After the telescopic cylinder 4 extends, it will be in one of the following three states depending on the position of the fence-shaped metal plate 10:
[0038] State 1: The gap-finding wheel 84 on the gap-finding mechanism 8 at the lower end of the telescopic cylinder 4 is unobstructed and falls directly between the two fence plates 1002, directly contacting the gap bottom 1003. The laser cutting head 7 follows the gap-finding mechanism 8 and falls to the position between the two fence plates 1002 (but does not directly contact the gap bottom 1003). At this time, the vibration motor 9 is turned off, the laser cutting head 7 is started, and the servo slide 1 is started to work. The servo slide 1 drives the sliding plate 101 to move. The sliding plate 101 drives the translation bracket 2 on it to move. The telescopic cylinder 4, the cutting head bracket 71, and the laser cutting head 7 connected to the translation bracket 2 move together to cut the gap bottom 1003 of the fence-type metal plate 10 until a fence-type metal plate 10 is cut into two pieces from the cut gap bottom 1003.
[0039] State 2: The gap-finding wheel 84 on the gap-finding mechanism 8 at the lower end of the telescopic cylinder 4 is blocked, but only on the side (not directly below). Under the continuous downward pressure of the telescopic cylinder 4, the gap-finding wheel 84 will roll, entering between two sets of fence plates 1002 and rolling towards the gap bottom 1003. At this time, the horizontal position of the gap-finding wheel 84 changes slightly, which in turn slightly changes the horizontal position of the lower end of the gap-finding mechanism 8, and consequently slightly changes the horizontal position of the lower end of the telescopic cylinder 4 connected to the gap-finding mechanism 8. To adapt to this change, the telescopic cylinder 4 will deflect around the end of the beam 3, and the return spring 6 will extend or be compressed to store elastic potential energy. Because the central axis of the laser cutting head 7 and the central axis of the gap-finding wheel 84 are located in the same plane, The gap-finding wheel 84, which rolls down between the two sets of fence plates 1002, guides the laser cutting head 7 to also enter between the two sets of fence plates 1002. At this time, the vibration motor 9 is turned off, the laser cutting head 7 is started, and the servo slide 1 is started to work. The servo slide 1 drives the sliding plate 101 to move, and the sliding plate 101 drives the translation bracket 2 on it to move accordingly. The telescopic cylinder 4, the cutting head bracket 71, and the laser cutting head 7 connected to the translation bracket 2 move accordingly to cut the bottom 1003 of the gap of the fence-type metal plate 10 (the cutting point is not necessarily the middle of the bottom 1003) until a fence-type metal plate 10 is cut into two pieces from the cut bottom 1003. (In order to ensure that the gap-finding mechanism 8 has enough deflection space, the width of the wheel frame must be smaller than the gap between the two sets of fence plates 1002. The width of the wheel frame can be adaptively replaced.)
[0040] State 3: The gap-finding wheel 84 on the gap-finding mechanism 8 at the lower end of the telescopic cylinder 4 is blocked, but it is blocked directly below the gap-finding wheel 84 (not blocked from the side). At this time, under the continuous downward pressure of the telescopic cylinder 4, because the gap-finding wheel 84 is blocked and limited, the slide rod 81, wheel frame 82, holding spring 83, and gap-finding wheel 84 as a whole will not change position. However, the moving end of the telescopic cylinder 4 is continuously pressing down, so the slide rod 81 will slide relative to the moving end of the telescopic cylinder 4. As a result, the holding spring 83 is compressed and stores elastic potential energy. The holding spring 83 will cause the wheel frame 82 and the gap-finding wheel 84 to receive a downward elastic force. Because of the operation of the vibration motor 9, the wheel frame 82 and the gap-finding wheel 84 will vibrate and swing left and right. The bottom position of the gap-finding wheel 84 will shift. When the vibration state meets the criteria of State 2 at a certain moment, that is, the gap-finding wheel on the gap-finding mechanism 8 at the lower end of the telescopic cylinder 4... 84 is obstructed, but only on the side (not directly below); under the elastic force of the holding spring 83, the wheel frame 82 and the finding wheel 84 will move downwards rapidly, similar to the principle in state two, causing the finding wheel 84 to roll and enter between the two sets of fence plates 1002. The obstruction of the finding wheel 84 is released, and the return spring 6 returns to its original position. In this state, the return spring 6 is mainly used to buffer the downward pressure of the telescopic cylinder 4, preventing the telescopic cylinder 4 from directly pressing down on the fence plate 1002 through the finding wheel 84 and damaging the fence-type metal plate 10 when it is obstructed directly below and has not yet vibrated and deflected. The retractable return spring 6 buffers the downward pressure, giving the finding wheel 84 sufficient time to vibrate and deflect, and also preventing damage to the fence-type metal plate 10. Then, similar to state two (the same principle will not be repeated), the fence-type metal plate 10 is cut.
[0041] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
