Description

Technical Field

[0001] The present invention relates to a feeding device, in particular to a feeding device for metal plate cutting. Background Art

[0002] In the existing metal plate cutting process, when a large-area metal plate needs to be cut into small pieces, cutting knives distributed horizontally and vertically are usually used to directly perform planar cutting. At this time, the small metal plates after cutting often lie flat on the horizontal plane. This cutting method makes the collection and stacking of the small metal plates after cutting very cumbersome, requiring a large amount of manual intervention, which is both time-consuming and laborious. Especially in mass production, the problem of low efficiency is particularly prominent. Summary of the Invention

[0003] The purpose of the present invention is to provide a feeding device for metal plate cutting. Through the combination of palletizing and sawing, after two sawings, a palletized stack of plate groups can be directly formed, facilitating subsequent blanking collection, and subsequent operations are also relatively time-saving and labor-saving.

[0004] The present invention provides the following technical solutions:

[0005] A feeding device for metal plate cutting includes multiple groups of support platforms arranged side by side, a pair of jaw groups with adjustable spacing below the support platforms, and a clamping and rotating group above the support platforms. There is a cutting gap for a sawing knife to perform longitudinal cutting between adjacent two groups of support platforms. After the metal plate is fed and placed on the support platform, it is longitudinally sawn into multiple groups of longitudinally cut plate strips by the sawing knife. A pair of jaw groups are used to clamp the two ends of the longitudinally cut plate strips one by one and drive the longitudinally cut plate strips to rise. There is an equal-height rising gap between adjacent longitudinally cut plate strips, and there is a staggered rising height between any two groups of longitudinally cut plate strips. The clamping and rotating group is distributed across both sides of the longitudinally cut plate strips, and through an inward-clamping and opposite movement, the layered longitudinally cut plate strips are aggregated into a palletized stack of longitudinally cut plate groups, and the longitudinally cut plate groups are driven to rotate 90° and placed on the support platform. Then, the longitudinally cut plate groups are longitudinally sawn again by the sawing knife to form multiple groups of plate cutting units. After a pair of jaw groups are adjusted to adapt to the width of the clamped plate cutting units and drive the plate cutting units to rise again, there is an equal-height rising gap between adjacent plate cutting units, and there is a staggered rising height between any two groups of plate cutting units. Subsequently, the clamping and rotating group again aggregates the layered plate cutting units into a palletized stack of palletized plate groups through an inward-clamping and opposite movement;

[0006] Thus, after two sawings of the metal plate, a palletized stack of palletized plate groups can be directly formed. During blanking, the palletized plate groups can be directly blanked and transported at one time, facilitating subsequent blanking collection, and subsequent operations are also relatively time-saving and labor-saving;

[0007] The process of the two sawing operations is specifically as follows: The metal plate is loaded onto the support table. Then, the sawing blade performs longitudinal sawing on the metal plate to form it into multiple groups of longitudinally cut slats. A pair of jaw groups clamp the two ends of the longitudinally cut slats in a one-to-one correspondence, and drive the longitudinally cut slats to rise, so that there is an equal-height rising gap between adjacent longitudinally cut slats, and there is a staggered rising height between any two groups of longitudinally cut slats. In order for the subsequent clamping and rotating group to aggregate the layered longitudinally cut slats into a longitudinally cut slat group stacked in a pallet through the inwardly clamping and opposite movement, and drive the longitudinally cut slat group to rotate 90° and place it on the support table again. At this time, the sawing blade performs longitudinal sawing on the longitudinally cut slat group again to form it into multiple groups of plate-cutting units. A pair of jaw groups clamp the two ends of the plate-cutting units in a one-to-one correspondence, and drive the plate-cutting units to rise again, so that there is an equal-height rising gap between adjacent plate-cutting units, and there is a staggered rising height between any two groups of plate-cutting units. Then, the clamping and rotating group aggregates the layered plate-cutting units into a palletized stack of palletized plate groups through the inwardly clamping and opposite movement again. Thus, one-time block loading and cutting of the metal plate is completed. After the sawing is completed, the palletized stack of palletized plate groups can be directly unloaded, which is relatively time-saving and labor-saving.

[0008] Preferably, one jaw group is correspondingly installed on a set of table plates. The two ends of the table plates are provided with sliders slidably installed on the base table. The distance between the two sets of table plates is adjusted by a first lead screw. A second lead screw is also arranged between the two first lead screws. The two ends of the second lead screw are rotatably installed on the base table. The sliding block screwed outside the second lead screw is slidably installed on the base table, and its two ends are rotatably installed outside the two first lead screws.

[0009] Thus, in order to adapt to the clamping distance at both ends of the longitudinally cut slats and the plate-cutting units, it is only necessary to drive the first lead screw to rotate to adjust the distance between the two sets of table plates. And by setting the second lead screw, the two sets of table plates can drive the two sets of jaw groups to move linearly. Then, the longitudinally cut slats and the plate-cutting units after sawing can be clamped to adjust their distances from the sawing blade. It can also be realized by clamping one end of the metal plate or the longitudinally cut slat group and moving in one direction during sawing to perform linear sawing. At this time, the sawing blade can use a saw blade driven by a motor to rotate, without the need for the saw blade to perform a horizontal linear movement, and only need to lower the saw blade to the height of the metal plate.

[0010] Preferably, the first screw rod is provided with two groups, and both are distributed parallel to the second screw rod, and a guide groove is opened axially therein, and both ends thereof are guided through the two groups of table plates, and a guide block which is clamped in the guide groove is also provided in the table plate, and two groups of external gear rings which rotate in opposite directions to the first screw rod are screwed on the outside of the first screw rod, and the external gear rings are installed in the table plate for transfer, and a first driving motor is installed on the table plate, and an external gear meshing with the external gear ring is installed on the driving end of the first driving motor. Therefore, when the first driving motor is started, the external gear ring can be driven to rotate, because the external gear ring is screwed to the first screw rod, and the external gear ring is connected to the table plate along the axial guidance, the rotation of the external gear ring can drive the two groups of table plates to move toward or away from the first screw rod, and a transfer block is also provided in the middle of the first screw rod, and the transfer block is installed in the sliding block for transfer, and the second screw rod is driven to rotate by the second driving motor installed on the base.

[0011] Preferably, a group of clamping jaws on a group of table plates corresponds to a plurality of groups of clamping jaw units distributed in a linear shape, and the clamping jaw units on the two groups of table plates are arranged in a one-to-one correspondence for clamping at both ends of the longitudinal cutting strips or the plate cutting units, and each group of clamping jaw units is correspondingly installed on a group of screw blocks, and the screw blocks are slidably installed on the table plates and driven by the corresponding third screw rods to perform linear reciprocating motion. The plurality of groups of third screw rods on a group of table plates are also distributed in a linear shape, and the third screw rod and the first screw rod are distributed perpendicularly. Therefore, when the two groups of relative clamping jaw units are correspondingly clamped at the two ends of the longitudinal cutting strips or the plate cutting units, the third screw rod is driven to rotate, and the longitudinal cutting strips or the plate cutting units can be driven by the clamping jaw units to approach each other and overlap in an offset manner, so that the subsequent engaging rotation group can be driven to engage and form the longitudinal cutting plate group or the stacking plate group.

[0012] Preferably, the clamping jaw unit includes a lifting cylinder installed on the screw block, a bottom clamping plate installed on the driving end of the lifting cylinder, a mounting plate fixed above the bottom clamping plate by a vertical plate, a clamping cylinder installed on the mounting plate, and a top clamping plate installed on the driving end of the clamping cylinder and moving toward the bottom clamping plate to clamp the longitudinal cutting strips or the board cutting unit. At this time, due to the setting of the clamping cylinder, the adjustable range of the distance between the bottom clamping plate and the top clamping plate can be increased, so that it can adapt to the clamping of the longitudinal cutting strips of a single-layer structure, and can also better adapt to the clamping of the board cutting unit of a multi-layer structure.

[0013] Preferably, a plurality of groups of rollers are arranged side by side on the support platform so that the metal sheet can roll rather than slide along the support platform when loading, so as to reduce the surface wear of the support platform.

[0014] Preferably, the clamping and rotating assembly includes a first mounting top installed at the driving end of the rotating cylinder, a linear module installed on the first mounting top, a second mounting top installed at the driving end of the linear module, and a clamping driving member installed on the second mounting top. When the clamping driving member makes an inward clamping movement towards each other, the linear driving direction of the linear module is the same as the clamping driving direction of the clamping driving member and the driving direction of the third lead screw.

[0015] Preferably, the clamping driving member includes a fourth lead screw mounted on the second mounting top, a driving rod driven by the fourth lead screw to perform linear reciprocating motion, and a fixing rod located at one end of the fourth lead screw and fixed on the second mounting top. The fixing rod is opposite to the driving rod, and a horizontally opposite support member is also vertically arranged at the bottom end of the driving rod. Thus, when the clamping operation is performed, the linear module can drive the fixing rod through the second mounting top to be placed on one side of the longitudinal cutting slats or the plate cutting unit at the bottom layer of one end, and the support member is located below the longitudinal cutting slats or the plate cutting unit. Then, the motor is started to rotate the fourth lead screw. At this time, the driving rod can be located on one side of the longitudinal cutting slats or the plate cutting unit at the top layer and move towards one side of the longitudinal cutting slats or the plate cutting unit at the bottom layer. During the movement, the longitudinal cutting slats or the plate cutting units can be sequentially driven to be stacked and aggregated. During the stacking and aggregation, the bottom clamping plate and the top clamping plate are limited at both ends of the longitudinal cutting slats or the plate cutting unit. And when the adjacent longitudinal cutting slats or the plate cutting units approach, the top clamping plate is driven by the clamping cylinder to open the mouth away from the bottom clamping plate to receive the longitudinal cutting slats or the plate cutting unit at the upper layer.

[0016] The beneficial effects of the present invention are as follows: The feeding device for metal plate cutting provided by the present invention realizes that after two saw cuts, the palletizing plate group can be directly formed through the combination of palletizing and sawing, which is convenient for subsequent blanking and collection, and the subsequent operations are also time-saving and labor-saving. Specifically: First, the metal plate is fed onto the support table, and then the sawing knife longitudinally saws the metal plate to form multiple groups of longitudinally cut slats. A pair of clamping jaw groups are respectively clamped at both ends of the longitudinally cut slats, and the longitudinally cut slats are driven to rise, so that there is an equal-height rising gap between adjacent longitudinally cut slats, and there is a staggered rising height between any two groups of longitudinally cut slats, so that the subsequent holding and rotating group can polymerize the stratified longitudinally cut slats into a palletized stack of longitudinally cut plate groups through the inward-facing movement of horizontal inward holding, and drive the longitudinally cut plate group to rotate 90° and place it on the support table again. At this time, the sawing knife longitudinally saws the longitudinally cut plate group again to form multiple groups of plate cutting units. A pair of clamping jaw groups are respectively clamped at both ends of the plate cutting units, and the plate cutting units are driven to rise again, so that there is an equal-height rising gap between adjacent plate cutting units, and there is a staggered rising height between any two groups of plate cutting units. Then the holding and rotating group again polymerizes the stratified plate cutting units into a palletized stack of palletizing plate groups through the inward-facing movement of inward holding. Thus, one-time block feeding and cutting of the metal plate are completed. After sawing, the blanking of the palletized stack of palletizing plate groups can be directly carried out, which is time-saving and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0030] Example 1

[0031] Such as Figures 1-10As shown in the figure, a feeding device for metal plate cutting. In this embodiment, it includes multiple groups of support platforms 1 arranged side by side, a pair of jaw groups 2 with adjustable spacing below the support platforms 1, and a clamping and rotating group 3 above the support platforms 1. There is a cutting gap for the saw blade 4 to perform longitudinal cutting between two adjacent support platforms 1. After the metal plate 5 is fed, it is placed on the support platform 1 and longitudinally sawed into multiple groups of longitudinal cut strips 6 by the saw blade 4. A pair of jaw groups 2 are used to clamp the two ends of the longitudinal cut strips 6 one by one and drive the longitudinal cut strips 6 to rise. There is an equal-height rising gap between adjacent longitudinal cut strips 6, and there is a staggered rising height between any two groups of longitudinal cut strips 6. The clamping and rotating group 3 is distributed across both sides of the longitudinal cut strips 6 and gathers the layered longitudinal cut strips 6 into a stacked longitudinal cut group 7 through an inward-clamping movement towards each other, and drives the longitudinal cut group 7 to rotate 90° and place it on the support platform 1. Then, the longitudinal cut group 7 is longitudinally sawed again by the saw blade 4 to form multiple groups of plate cutting units. After a pair of jaw groups 2 are adjusted to adapt to the width of the clamped plate cutting units, they drive the plate cutting units to rise again, so that there is an equal-height rising gap between adjacent plate cutting units, and there is a staggered rising height between any two groups of plate cutting units. Then, the clamping and rotating group 3 again gathers the layered plate cutting units into a stacked palletized plate group through an inward-clamping movement towards each other;

[0032] Thus, after two sawing operations on the metal plate 5, a stacked palletized plate group can be directly formed. During discharging, the palletized plate group can be directly discharged and transported at one time, which is convenient for subsequent discharging and collection, and the subsequent operations are also relatively time-saving and labor-saving;

[0033] The specific process of the two sawing operations is as follows: The metal plate 5 is fed onto the support platform 1, and then the saw blade 4 longitudinally saws the metal plate 5 to form multiple groups of longitudinal cut strips 6. A pair of jaw groups 2 clamp the two ends of the longitudinal cut strips 6 one by one and drive the longitudinal cut strips 6 to rise, so that there is an equal-height rising gap between adjacent longitudinal cut strips 6, and there is a staggered rising height between any two groups of longitudinal cut strips 6, so that the subsequent clamping and rotating group 3 can gather the layered longitudinal cut strips 6 into a stacked longitudinal cut group 7 through a horizontally inward-clamping movement towards each other and drive the longitudinal cut group 7 to rotate 90° and place it on the support platform 1 again. At this time, the saw blade 4 longitudinally saws the longitudinal cut group 7 again to form multiple groups of plate cutting units. A pair of jaw groups 2 clamp the two ends of the plate cutting units one by one and drive the plate cutting units to rise again, so that there is an equal-height rising gap between adjacent plate cutting units, and there is a staggered rising height between any two groups of plate cutting units. Then, the clamping and rotating group 3 again gathers the layered plate cutting units into a stacked palletized plate group through an inward-clamping movement towards each other. Thus, one block feeding and cutting of the metal plate 5 is completed. After sawing, the stacked palletized plate group can be directly discharged, which is relatively time-saving and labor-saving.

[0034] Example 2

[0035] A loading device for metal plate cutting. In this embodiment, it is a further limitation based on Embodiment 1. Among them, a set of clamping jaws 2 is correspondingly installed on a set of table boards 21. Both ends of the table board 21 are provided with sliders 23 slidably installed on the bottom table 22. And the distance between the two sets of table boards 21 is adjusted by a first screw rod 24. A second screw rod 25 is also arranged between the two sets of first screw rods 24. Both ends of the second screw rod 25 are rotatably installed on the bottom table 22. A sliding block 26 screwed outside the second screw rod 25 is slidably installed on the bottom table 22, and both ends thereof are rotatably installed outside the two sets of first screw rods 24;

[0036] So far, in order to adapt to the clamping distance at both ends of the longitudinal cutting strip 6 and the plate cutting unit, it is only necessary to drive the first screw rod 24 to rotate to adjust the distance between the two sets of table boards 21. And by setting the second screw rod 25, the two sets of table boards 21 can drive the two sets of clamping jaws 2 to move linearly. Then, the longitudinal cutting strip 6 and the plate cutting unit after sawing can be clamped to adjust their distance from the saw blade 4. It can also be sawed linearly by clamping one end of the metal plate 5 or the longitudinal cutting plate group 7 and moving in one direction during sawing. At this time, the saw blade 4 can be a saw blade driven by a motor to rotate, and there is no need to make the saw blade perform a horizontal linear motion. It is only necessary to lower the saw blade to the height of the metal plate 5.

[0037] There are two sets of the first screw rods 24, and they are all parallel to the second screw rod 25. A guiding groove 241 is axially formed inside it. Both ends thereof are guided through the two sets of table boards 21. And guiding blocks 242 clamped in the guiding groove are also arranged inside the table board 21. Two external gear rings 27 with opposite rotation directions to the first screw rod 24 are also screwed outside the first screw rod 24. And the external gear rings 27 are rotatably installed inside the table board 21. A first driving motor 28 is installed on the table board 21. An external gear meshing with the external gear ring 27 is installed at the driving end of the first driving motor 28. Therefore, when the first driving motor 28 is started, the external gear ring 27 can be driven to rotate. Since the external gear ring 27 is screwed to the first screw rod 24 and the external gear ring 27 is axially guided and connected inside the table board 21, the rotation of the external gear ring 27 can drive the two sets of table boards 21 to move towards or away from each other relative to the first screw rod 24. A transfer block 29 is also arranged in the middle of the first screw rod 24. The transfer block 29 is rotatably installed inside the sliding block 26. The second screw rod 25 is driven to rotate by a second driving motor installed on the bottom table 22.

[0038] The clamping jaws 2 on one set of table 21 correspond to a plurality of sets of clamping jaw units 210 distributed in a linear manner, and the clamping jaw units 210 on the two sets of table 21 are arranged one by one, and are used to clamp the two ends of the longitudinal cutting strip 6 or the plate cutting unit. Each set of clamping jaw units 210 is correspondingly installed on a set of screw blocks 211, and the screw blocks 211 are slidably installed on the table 21 and driven by the corresponding third screw rod 212 to make a linear reciprocating motion. The multiple groups of third screw rods 212 on 21 are also distributed in a straight line, and the third screw rods 212 and the first screw rods 24 are distributed vertically. Therefore, when the two groups of relative jaw units 210 are clamped on the two ends of the longitudinal cutting strips 6 or the plate cutting units respectively, the third screw rods 212 are driven to rotate. The longitudinal cutting strips 6 or the plate cutting units can be driven by the jaw units 210 to approach each other and overlap in an offset manner, so that the subsequent engaging rotation group 3 can be driven to engage and form the longitudinal cutting plate group 7 or the stacking plate group.

[0039] The clamping unit 210 includes a lifting cylinder 213 installed on a screw block 211, a bottom clamping plate 214 installed on the driving end of the lifting cylinder 213, a mounting plate 216 fixed above the bottom clamping plate 214 through a vertical plate 215, a clamping cylinder 217 installed on the mounting plate 216, and a top clamping plate 218 installed on the driving end of the clamping cylinder 217 and moving toward the bottom clamping plate 214 to clamp the longitudinal cutting strips 6 or the board cutting unit. At this time, due to the setting of the clamping cylinder 217, the adjustable range of the distance between the bottom clamping plate 214 and the top clamping plate 218 can be increased, so that it can adapt to the clamping of the longitudinal cutting strips 6 of a single-layer structure, and can also better adapt to the clamping of the board cutting unit of a multi-layer structure.

[0040] A plurality of rollers 11 are arranged side by side on the support platform 1 so that the metal plate 5 can roll rather than slide along the support platform 1 when being loaded, so as to reduce the surface wear of the support platform 1 .

[0041] The engaging rotation group 3 includes a first mounting top 32 installed on the driving end of the rotating cylinder 31, a linear module 33 installed on the first mounting top 32, a second mounting top 34 installed on the driving end of the linear module 33, and an engaging driving member installed on the second mounting top 34. When the engaging driving member moves inwardly toward each other, the linear driving direction of the linear module 33 is the same as the engaging driving direction of the engaging driving member and the driving direction of the third screw rod 212.

[0042] The clamping drive member includes a fourth lead screw 35 mounted on the second mounting top 34, a drive rod 36 driven by the fourth lead screw 35 to perform linear reciprocating motion, and a fixed rod 37 located at one end of the fourth lead screw 35 and fixed on the second mounting top 34. The fixed rod 37 is opposite to the drive rod 36, and horizontal support members are vertically arranged opposite to the bottom end of the drive rod 36. Thus, when performing the clamping operation, the linear module 33 can drive the fixed rod 37 through the second mounting top 34 to be placed on one side of the longitudinal cutting slats 6 or the plate cutting unit at the bottom layer at one end, and the support members are located below the longitudinal cutting slats 6 or the plate cutting unit. Then, the motor is started to rotate the fourth lead screw 35. At this time, the drive rod 36 can be located on one side of the longitudinal cutting slats 6 or the plate cutting unit at the top layer and move towards one side of the longitudinal cutting slats 6 or the plate cutting unit at the bottom layer. During the movement, the longitudinal cutting slats 6 or the plate cutting units can be sequentially driven to be stacked and gathered. During the stacking and gathering, the bottom clamping plate 214 and the top clamping plate 218 are limited at both ends of the longitudinal cutting slats 6 or the plate cutting unit. And when the adjacent longitudinal cutting slats 6 or the plate cutting units approach, the top clamping plate 218 is driven by the clamping cylinder 217 to open the mouth from the bottom clamping plate 214 to receive the longitudinal cutting slats 6 or the plate cutting unit at the upper layer.

[0043] The working principle of the present invention is as follows: An upper feeding device for cutting a metal plate 5 provided by the present invention realizes that after two saw cuts, a palletized plate group can be directly formed through the combination of palletizing and sawing, so as to facilitate subsequent blanking and collection, and the subsequent operations are also relatively time-saving and labor-saving. Specifically: First, the metal plate 5 is fed onto the support table 1, and then the sawing knife 4 performs longitudinal sawing on the metal plate 5 to form it into multiple groups of longitudinal cutting slats 6. A pair of clamping jaw groups 2 are respectively clamped at both ends of the longitudinal cutting slats 6, and the longitudinal cutting slats 6 are driven to rise, so that there is an equal rising gap between adjacent longitudinal cutting slats 6, and there is a staggered rising height between any two groups of longitudinal cutting slats 6, so that the subsequent clamping and rotating group 3 can gather the stratified longitudinal cutting slats 6 into a palletized stacked longitudinal cutting plate group 7 through the inward clamping and opposite movement, and drive the longitudinal cutting plate group 7 to rotate 90° and place it on the support table 1 again. At this time, the sawing knife 4 performs longitudinal sawing on the longitudinal cutting plate group 7 again to form it into multiple groups of plate cutting units. A pair of clamping jaw groups 2 are respectively clamped at both ends of the plate cutting units, and the plate cutting units are driven to rise again, so that there is an equal rising gap between adjacent plate cutting units, and there is a staggered rising height between any two groups of plate cutting units. Then, the clamping and rotating group 3 again gathers the stratified plate cutting units into a palletized stacked palletized plate group through the inward clamping and opposite movement. Thus, one-time block feeding and cutting of the metal plate 5 are completed. After sawing, the blanking of the palletized stacked palletized plate group can be directly carried out, which is relatively time-saving and labor-saving.
