Description

Technical Field

[0001] The utility model relates to the technical field of steel plate shearing, in particular to a material unloading positioning platform of a hydraulic shearing machine. Background Art

[0002] Shearing machine is used for the automated cutting process of plates and is a common production and processing equipment. After the produced plates are cut by the shearing machine, they need to be stacked and then sent for packaging. After the existing shearing machine unloads the materials, it needs to be stacked manually, which has slow unloading speed, low operation efficiency, high labor intensity, poor stacking neatness, and seriously restricts the production and processing process of the assembly line. In order to improve the efficiency of unloading and stacking of sheared plates, some shearing machines are equipped with a unloading and sorting function, such as the invention patent application "A kind of automatic material sorting shearing machine with adjustable spacing" with application publication number CN 110842270 A, which includes a shearing machine body, a feed table is fixedly installed on one side of the shearing machine body, a rotating plate at the lower end discharge port of the shearing machine body is connected to a unloading plate, an L-shaped fixed plate is fixedly connected to the lower end side wall of the shearing machine body, the vertical part of the L-shaped fixed plate and the side wall of the shearing machine body facing each other are rotatably connected with the same adjusting screw through a ball bearing, the rod wall of the adjusting screw is threadedly connected with a movable screw ring, the upper end of the movable screw ring is rotatably connected with a push-pull rod, and the upper end of the push-pull rod is rotatably connected to the lower end of the unloading plate. The shearing machine starts the adjustment motor according to the height of the plates to be stacked by setting the blanking plate, and the adjustment motor drives the adjustment screw to rotate. The threaded connection between the adjustment screw and the moving screw ring allows the moving screw ring to push and pull the blanking plate through the push-pull rod, so that the blanking height of the blanking plate can be quickly and conveniently adjusted, so as to achieve rapid control of the stacking height of the plates. Although the shearing machine improves the stacking efficiency of the sheared plates, it also has obvious defects. When the lower layer of the stacked plates is discharged, the blanking plate needs to be tilted at a large angle. Under the deadweight of the steel plate, the plate has a large sliding inertia, which is easy to cause a large impact on the buffer baffle. When side sliding occurs, it will also cause cutting injuries to the operator next to it. Moreover, when the next sheared plate slides down at a large angle, its edge will impact the previous sheared plate at a large cutting angle, which will cause scratch damage to the surface of the previous sheared plate.

For ordinary technicians in this field, the specific meanings of the above terms in this utility can be understood according to specific circumstances.

[0024] See also Figure 1 , Figure 2 and Figure 3 As shown in the figure, the embodiment of the utility model proposes a material unloading and positioning platform for a hydraulic shearing machine, the material unloading and positioning platform includes a horizontal conveying device 1 arranged at the unloading end of the hydraulic shearing machine 100 and a plate material alignment and positioning device 2 connected with the horizontal conveying device 1, and a loading end of the hydraulic shearing machine 100 is provided with a loading conveying platform 110, and a plate pusher 120 is provided on the loading conveying platform 110, and the plate pusher 120 is used to push the plate placed on the loading conveying platform 110 into the hydraulic shearing machine 100, and the plate sheared by the hydraulic shearing machine 100 is then sent to the plate material alignment and positioning device 2 through the horizontal conveying device 1, and finally aligned through the plate material alignment and positioning device 2, and then clamped and transported to the stacking rack by the matching plate material gripper manipulator. Among them, Figure 1 As shown, the sheet material alignment and positioning device 2 includes a movable base 21 and a sheet material alignment adjustment platform 22 disposed on the base 21. Figure 2As shown, the sheet alignment adjustment platform 22 includes a rectangular profile frame 221, and a horizontal steel plate 222 is fixed to the upper surface of the profile frame 221. The horizontal steel plate 222 is provided with a plurality of parallel strip slots 2221 with equal spacing along its length direction. The strip slots 2221 are slots that penetrate the horizontal steel plate 222, and the extension direction of the strip slots 2221 is parallel to the width direction of the horizontal steel plate 222. The lower surface of the horizontal steel plate 222 is provided with a guide rod 223 at the strip slots 2221 for aligning the sheet to the outer edge of the horizontal steel plate 222. Figure 2 As shown, in order to reduce the resistance and friction of the sheared sheet sliding on the guide rod 223, the upper end rod surface of the guide rod 223 is provided with a roller groove distributed along the length direction of the guide rod 223, and a plurality of rolling elements 2231 are provided in the roller groove, and the spacing between adjacent rolling elements 2231 is 0.5 to 1.0 cm. As a preferred embodiment of the utility model, the rolling element 2231 is a directional roller or a ball.

[0025] In order to facilitate the adjustment of the inclination angle of the guide rods 223, a swing angle adjustment mechanism is provided in the profile frame 221, which is synchronously linked with each guide rod 223 to drive each guide rod 223 to be synchronously tilted at the same angle. When the sheared sheet is sent from the horizontal conveyor 1 to the sheet alignment and positioning device 2, the swing angle adjustment mechanism on the sheet alignment and positioning device 2 is activated, so that each guide rod 223 completes the angle adjustment synchronously. The adjustment state is as follows: Figure 2 and Figure 3 As shown, at this time, each guide rod 223 is tilted at one end close to the horizontal conveying device 1, and is sunk at the end away from the horizontal conveying device 1, and the entire guide rod 223 is in an inclined state, so that the sheared sheet placed on the horizontal steel plate 222 is tilted at a smaller angle and guided to the outer end of the base 21 along the direction, so that one side of the sheared sheet is aligned.

[0026] Further, in a preferred embodiment of the present invention, Figure 1As shown, when the guide rod 223 is at the maximum inclination angle, the horizontal plane where the tilted end close to one end of the horizontal conveyor 1 is located is lower than the height of at least one plate thickness unit on the upper surface of the horizontal conveyor 1. Through the design of this height difference, the sheared sheet material sent from the horizontal conveyor 1 to the horizontal steel plate 222 can be transferred with a smaller drop, so as to avoid the sheared sheet material under a large drop from scratching the surface of the previous sheared sheet material on the horizontal steel plate 222. Under the height difference of at least one plate thickness unit, after the sheared sheet material sent to the horizontal steel plate 222 is guided and aligned by the guide rod 223, the aligned sheared sheet material can be clamped and transported to the stacking rack by the matching sheet material clamping claw manipulator. At this time, under the height difference of at least one plate thickness unit, the sheared sheet material on the horizontal steel plate 222 can be clamped and transported by aligning one by dropping, or by stacking and aligning two sheared sheets on the horizontal steel plate 222 and then clamped and transported. This structural design can prevent the sheared sheet from sliding at a large angle when being sent from the horizontal conveyor 1 to the horizontal steel plate 222, and can reduce the downward inertia of the sheared sheet when being aligned.

[0027] Further, in a preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, the outer edge of the base 21 is provided with a vertical upward positioning lever 211, wherein a clearance space 212 is provided between the positioning lever 211 and the outer edge of the horizontal steel plate 222 for the sheet material clamping claw to pass through. When the outer edge of the sheared sheet material is aligned at the positioning lever 211, the matching sheet material clamping claw manipulator can put the clamping claw into the clearance space 212. At this time, the other side edge of the sheared sheet material also has a suspended distance from the upper surface of the horizontal steel plate 222 under the action of the tilted guide rod 223, which facilitates the sheet material clamping claw manipulator to insert the clamping claw into the suspended position, thereby lifting and grabbing the two side edges of the sheared sheet material, which is convenient for the clamping claw manipulator. After the sheared sheet material is clamped and fixed, the sheet material clamping claw manipulator clamps and transports the aligned sheared sheet material to the stacking rack.

[0028] Further, in a preferred embodiment of the present invention, Figure 4 As shown, the swing angle adjustment mechanism includes a first long rod 224 away from the horizontal conveyor 1 and a second long rod 225 close to the horizontal conveyor 1, wherein, in order to enhance the structural strength, a web 226 is connected between the first long rod 224 and the second long rod 225, and both ends of each guide rod 223 are fixed to the first long rod 224 and the second long rod 225 through a connecting column 227. Figure 4 and Figure 5As shown, the profile frame 221 is provided with at least one electric hydraulic push rod 228 on one side close to the horizontal conveyor 1. The push rod of the electric hydraulic push rod 228 is rotatably connected to the center position of the second long rod 225, and the first long rod 224 is rotatably connected to the profile frame 221 via a rotating member. In some embodiments, the electric hydraulic push rod 228 can be set to be multiple synchronous ones, which can synchronously drive each guide rod 223, which is suitable for alignment operations with thicker plates and heavier plates after shearing. In some embodiments, as Figure 5 As shown, the rotating member includes a "U"-shaped rotating seat 229 fixed to the lower end surface of the first long rod 224 and a connecting seat 2291 fixed on the bottom profile of the profile frame 221. The connecting seat 2291 is provided with a lug 2292, which is assembled in the "U"-shaped rotating seat 229 and connected through a rotating shaft.

[0029] Further, in a preferred embodiment of the present invention, Figure 2 and Figure 4 As shown, the profile frame 221 is provided with a push rod fixing seat 2281 on one side close to the horizontal conveyor 1, and the bottom of the cylinder of the electric hydraulic push rod 228 is rotatably connected to the push rod fixing seat 2281 through a rotating support, and the push rod of the electric hydraulic push rod 228 is rotatably connected to the center position of the second long rod 225 through a rotating support. When the push rod of the electric hydraulic push rod 228 pushes the second long rod 225 to swing upward and lift, the guide rod 223 is in a state of being tilted upward. Figure 2 and Figure 5 When the push rod of the electric hydraulic push rod 228 pulls the second long rod 225 to swing downward obliquely, the guide rod 223 can completely fall into the strip-shaped slot 2221.

[0030] Further, in a preferred embodiment of the present invention, Figure 1 As shown, the horizontal conveying device 1 includes a support platform 11, a conveyor belt 12 located on the support platform 11, and a motor driving the conveyor belt 12. In order to enhance the support of the conveyor belt 12 on the sheet material, a plurality of support rollers 13 arranged at equal intervals are provided between the upper and lower belt bodies of the conveyor belt 12. The support rollers 13 are designed without power and can be passively rotated, or they can be designed with power and actively driven. Figure 1 As shown, the four corners of the bottom of the base 21 are provided with moving rollers 213 with brakes, and the left and right sides of the base 21 are provided with limit rails 3 on the ground, wherein the two moving rollers 213 on the side close to the horizontal conveyor 1 are fixed in the limit rails 3, and the two moving rollers 213 on the side away from the horizontal conveyor 1 are fixed to the ground with brakes. The limit rails 3 and the moving rollers 213 with brakes can prevent the base 21 from tilting to the side. When maintenance is required, the entire sheet alignment and positioning device 2 can be transferred by releasing the brakes of the moving rollers 213.
