[0037] Reference below Figures 1 to 6 A material collecting tooling of an embodiment of the first aspect of the utility model is described in detail.

[0038] refer to Figures 1 to 6 According to some embodiments of the present invention, a material receiving tool comprises a mounting seat 100, a guide structure 200 and a material receiving fixture 300, wherein the guide structure 200 comprises two guide members 210 arranged in parallel and tilted along a first direction, wherein the extension direction of the two guide members 210 is perpendicular to the first direction and is used to guide the workpiece to slide along the extension direction thereof; the two guide members 210 are arranged on the mounting seat 100 and can slide on the mounting seat 100 along the first direction, and the two guide members 210 are provided with first protrusions 211 on opposite sides of the first direction, and by adjusting the two guide members The distance between the guide members 210 enables the first protrusion 211 of the guide member 210 to abut against the two opposite bending portions of the workpiece, so that the workpiece can slide down stably along the guide member 210; wherein there are multiple material receiving jigs 300, each of which is used to receive and accommodate workpieces of different sizes, and any one of the multiple material receiving jigs 300 can be detachably connected to the guide structure 200, and when any material receiving jig 300 is connected to the guide structure 200, the feeding end of the material receiving jig 300 is connected to the lower end of the guide member 210, so as to receive the workpiece sliding down along the guide member 210.

[0039] It can be understood that the guide structure 200 is tiltedly arranged on the mounting seat 100. Since the two guide members 210 are slidably connected to the mounting seat 100 along the first direction, by adjusting the distance between the two guide members 210, the two outer end faces of the two guide members 210 that are opposite to each other can be adjusted to abut against the two opposite bending parts of the workpiece to be received, so that workpieces of different sizes can slide down along the two guide members 210; at the same time, since there are multiple material receiving jigs 300, which are respectively used to receive and accommodate workpieces of different sizes, the material receiving jig 300 that is compatible with the workpiece to be received can be selected according to the size of the workpiece to be received and connected to the guide structure 200, and since when the material receiving jig 300 is connected to the guide structure 200, the feeding end of the material receiving jig 300 is opposite to the lower end of the guide member 210, and the gap between the material receiving jig 300 and the two guide members 210 is smaller than the size of the workpiece, so that the workpiece sliding from the guide member 210 can automatically fall into the material receiving jig 300. Therefore, it can be known that the above-mentioned material receiving tool can receive workpieces of various sizes and specifications according to the size specifications of the workpiece to be received by changing the spacing between the guide members 210 and replacing the material receiving fixtures 300 of different specifications, and its versatility is better.

[0040] In some embodiments of the present invention, the guide structure further includes two positioning members 220, the two positioning members 220 are arranged opposite to each other and are slidably connected to the mounting seat 100 along the first direction, the two guide members 210 are respectively arranged on the two positioning members 220, and the material receiving fixture 300 is connected to the positioning members 220. For example, in one embodiment, Figures 1 to 2 As shown, the guide structure 200 also includes two positioning members 220, the two positioning members 220 are arranged opposite to each other, and two slide rails 120 are arranged on the mounting seat 100, the two slide rails 120 are arranged at intervals, and the extension direction of the slide rail 120 is the same as the first direction, the two positioning members 220 are respectively connected to the sliders connected to the slide rails 120, and the two positioning members 220 can slide stably along the slide rails 120 respectively, and the two guide members 210 are respectively connected to the two positioning members 220 by threaded fasteners. When the two positioning members 220 approach or move away from each other along the slide rails 120, the spacing between the two guide members 210 decreases or increases, so that it can guide workpieces of different sizes; the material receiving jig 300 is detachably arranged on the positioning member 220, and one end of the material receiving jig 300 is connected to the lower end of the guide member 210, so that the workpiece sliding out of the guide member 210 can be received by the material receiving jig 300. It is understandable that the guide member 210 is installed on the positioning member 220, and the material receiving fixture 300 is set on the positioning member 220. When the spacing of the guide members 210 needs to be adjusted, it is only necessary to adjust the spacing between the positioning members 220. The operation is simple, reduces manual labor intensity, and saves manpower.

[0041] In one embodiment, the receiving tool further includes a movable baffle 221, which is slidably connected to the positioning member 220, and is disposed on one side of the lower end of the guide member 210. One end of the movable baffle 221 can be close to or away from the guide member 210, so as to limit the workpiece from sliding out of the guide member 210. Figure 1 , Figure 2 and Figure 6As shown, the two positioning members 220 are each provided with a movable baffle 221, and the two movable baffles 221 can slide on the positioning members 220 respectively along the first direction, and the two movable baffles 221 are respectively arranged on one side of the lower end of the guide member 210 connected to the corresponding positioning member 220, and a limiting groove 221a is arranged at one end of the movable baffle 221 close to the guide member 210. When the movable baffle 221 is close to the guide member 210, the first protrusion 211 at the lower end of the guide member 210 is partially embedded in the limiting groove 221a. At this time, the movable baffle 221 can limit the workpiece from sliding out of the guide member 210. When the movable baffle 221 is away from the guide member 210 and the first protrusion 211 at the lower end of the guide member 210 moves out of the limiting groove 221a, the workpiece slides along the guide member 210 into the material receiving fixture 300. By setting a movable baffle 221 at the position where the guide member 210 and the material receiving jig 300 are connected, when the material receiving jig 300 receives a sufficient number of workpieces, the movable baffle 221 is moved close to the guide member 210, the material receiving jig 300 can be removed, and at the same time, the newly generated workpieces can be accumulated on the guide member 210 without affecting the production of the workpieces, thereby effectively improving the production efficiency of the workpieces.

[0042] It is understandable that in addition to being able to slide along the first direction, the movable baffle 221 can also adopt other methods that intersect with the extension direction of the guide member 210 in other embodiments to limit the workpiece from sliding out of the guide member 210, and the number of movable baffles 221 can also be adjusted and is not necessarily limited to two.

[0043] refer to Figure 1 and Figure 3 The material receiving jig 300 includes a pushing block 320 and a material receiving plate 310 arranged parallel to the guide member 210. A U-shaped groove 313 is provided at the lower end of the material receiving plate 310. The material receiving jig 300 is provided with second protrusions 312 on opposite sides of the first direction. The second protrusions 312 abut against two opposite bending portions of the workpiece so that the workpiece can be stably collected by the material receiving jig 300. The pushing block 320 is arranged on the material receiving plate 310 and can slide along the extension direction of the material receiving plate 310. A third positioning pin 311 is provided at one end of the material receiving plate 310 to limit the movement of the pushing block 320 at one end of the material receiving plate 310. When the material receiving plate 310 receives a certain number of workpieces, the workpieces are pushed out of the other end of the material receiving plate 310 by the pushing block 320. It is understandable that when collecting the workpiece, the material receiving fixture 300 is removed from the positioning member 220, and the workpiece is pushed out of the material receiving plate 310 by the push block 320, which reduces the difficulty of operation, reduces the intensity of manual labor, and improves production efficiency.

[0044] For example, Figures 1 to 3As shown, in one embodiment, a support portion 224 of a step structure is provided on the side where the two positioning members 220 are close to each other. By adjusting the spacing between the two positioning members 220, the support portion 224 is made to fit the bottom and side of the material receiving jig 300, so as to carry the material receiving jig 300 and limit the movement of the material receiving jig 300 in the first direction; a first positioning pin 224a is provided at the lower end of the support portion 224, which is used to limit the movement of the material receiving jig 300 in the extension direction of the guide member 210, so that the gap between the feeding end of the material receiving jig 300 and the lower ends of the two guide members 210 is smaller than the size of the workpiece, and the workpiece can slide from the guide member 210 into the material receiving jig 300. By providing a support portion 224 on the side where the positioning members 220 are close to each other to place the material receiving jig 300, when replacing the material receiving jig 300 of different specifications, it is only necessary to adjust the spacing between the positioning members 220 so that the material receiving jig 300 can be placed and docked with the guide member 210, which is simple to operate and reduces investment costs. It is understandable that in addition to using the first positioning pin 224a to limit the movement of the material receiving fixture 300, in some other embodiments, other structures with limiting functions such as limiting protrusions can be set on the support portion 224 to limit the movement of the workpiece in the extension direction of the guide member 210.

[0045] like Figure 2 and Figure 5 As shown, in some embodiments of the present invention, the ends of the support portions 224 of the two positioning members 220 that are close to each other are each provided with an avoidance groove 224d, and the avoidance groove 224d is each provided with a second positioning pin 224b, and the second positioning pin 224b is each penetrated by a U-shaped groove 313 of the material receiving fixture 300, and the second positioning pin 224b is respectively connected to the two mounting blocks 224c, and the two positioning members 220 are each provided with a second long hole 225 near the avoidance groove 224d, and the extension direction of the second long hole 225 is consistent with the extension direction of the guide member 210, and the two mounting blocks 224c are respectively arranged below the second long hole 225, and the threaded fastener passes through the second long hole 225 to connect the mounting block 224c below it and the positioning member 220. When it is necessary to replace the material receiving jig 300 of different specifications, if the first positioning pin 224a cannot make the gap between the feed end of the material receiving jig 300 and the lower ends of the two guide members 210 smaller than the workpiece size, the position of the second positioning pin 224b can be adjusted by adjusting the position of the threaded fastener in the second elongated hole 225, so that the second positioning pin 224b can abut against the groove wall of the U-shaped groove 313 parallel to the first direction, so that the butt gap between the feed end of the material receiving jig 300 and the lower end of the guide member 210 is smaller than the workpiece size, and the workpiece can slide from the guide member 210 into the material receiving jig 300. It can be understood that by providing the second elongated hole 225 and the second positioning pin 224b on the positioning member 220, it is ensured that the material receiving jig 300 of different specifications can cooperate well with the guide member 210.

[0046] In some embodiments of the present invention, the material receiving tool further includes a clamping bolt 223, and both positioning members 220 are provided with a first elongated hole 222, the extension direction of the first elongated hole 222 is parallel to the first direction, and the rod of the clamping bolt 223 is passed through the first elongated hole 222 and is threadedly connected to the mounting seat 100. Figure 1 and Figure 2 As shown, both positioning members 220 are provided with a first elongated hole 222, wherein the extension direction of the first elongated hole 222 is parallel to the first direction, the rod of the clamping bolt 223 is passed through the first elongated hole 222, and is threadedly connected to the mounting seat 100. When the positioning member 220 is adjusted to a suitable spacing, the positioning member 220 is fixed to the mounting seat 100 by rotating the head of the clamping bolt 223, thereby increasing the stability of the entire guide structure 200 and making it less likely for the workpiece to deviate during the receiving process; wherein the mounting seat 100 is provided with a plurality of threaded holes arranged at intervals along the first direction, when the clamping bolt 223 is connected to the mounting seat 100 through any one of the threaded holes, the spacing between the positioning members 220 can be adjusted by adjusting the position of the clamping bolt 223 in the first elongated hole 222, thereby increasing the adjustment range of the distance between the two positioning members 220, so that it can place a variety of specifications of material receiving fixtures 300, thereby realizing the reception of a variety of workpieces of different sizes.

[0047] In some embodiments of the present invention, the material receiving tool further includes a distance adjustment structure 110, which is disposed on the mounting seat 100 and connected to the outer end surfaces of the two positioning members 220 and is used to adjust the distance between the two positioning members 220. Figure 1 and Figure 2 As shown, the distance adjusting structure 110 is arranged between the two slide rails 120 of the mounting seat 100, wherein the distance adjusting structure 110 includes two adjusting bolts 111, and the two adjusting bolts 111 are both arranged along the first direction, and the rods of the two adjusting bolts 111 are rotatably connected to the side end surfaces of the two positioning members 220 respectively, and the rods of the two adjusting bolts 111 are both threadedly connected to the mounting seat 100, and the distance between the positioning members 220 can be accurately and stably adjusted by rotating the heads of the adjusting bolts 111.

[0048] In some embodiments of the present invention, a material receiving tool further includes a bracket 400, the bracket 400 is connected to the mounting seat 100, and the bracket 400 includes a height adjustment structure 410 and an angle adjustment structure 420 connected thereto, the height adjustment structure 410 is used to adjust the height of the mounting seat 100 and the guide member 210, and the angle adjustment structure 420 is used to adjust the inclination angle of the mounting seat 100 and the guide member 210. For example, Figure 1 and Figure 4As shown, the height adjustment structure 410 includes a bottom rod 411 and a movable rod 412, the movable rod 412 is arranged in the bottom rod 411, and can move up and down along the extension direction of the bottom rod 411, the angle adjustment structure 420 is composed of a movable rod 412 and an angle adjustment block 421, the upper end of the movable rod 412 is provided with a rotating groove 412a, and the two groove walls of the rotating groove 412a are each provided with two corresponding circular holes, the angle adjustment block 421 is provided with a circular hole and a crescent hole, the angle adjustment block 421 is placed in the rotating groove 412a, and the movable rod 412 and the angle adjustment block 421 are connected by two pin shafts through the circular hole and the crescent hole, so that the angle adjustment block 421 can rotate around the upper end of the movable rod 412, the rotation direction of the angle adjustment block 421 and the extension direction of the guide member 210 are in the same vertical plane, and a mounting seat 100 is provided on the angle adjustment block 421. It is understandable that when the movable rod 412 moves upward or downward, the movable rod 412 drives the mounting seat 100 on the angle adjustment block 421 to move upward or downward, thereby achieving the purpose of adjusting the height of the guide member 210; when the angle adjustment block 421 rotates around the upper end of the movable rod 412, the inclination angles of the mounting seat 100 and the guide member 210 on the mounting seat 100 are changed accordingly. Through the height adjustment structure 410 and the angle adjustment structure 420, the guide member 210 is docked with the production equipment to effectively guide the workpiece.

[0049] refer to Figure 1 and Figure 2 In some embodiments of the present invention, the receiving tool also includes an inspection block 500, which has a slide groove, and the inspection block 500 can be detachably mounted on the guide member 210 and the material receiving fixture 300 through the slide groove. The number of the inspection blocks 500 is the same as the number of the material receiving fixture 300, and the width of the slide groove in each inspection block 500 is 0.02mm larger than the single side of the material receiving fixture 300. By sliding the inspection block on the guide member 210 and the material receiving fixture 300, it is checked whether the workpiece slides smoothly on the guide member 210 and the material receiving fixture 300, so as to avoid the workpiece from getting stuck during production and processing, thereby affecting production efficiency.

[0050] The following describes the bending equipment of the second embodiment of the utility model. The bending equipment according to the second embodiment of the utility model includes a material receiving fixture of the first embodiment. By using the material receiving fixture in the bending equipment, when the bending equipment needs to produce and process workpieces of different specifications, it only needs to adjust the spacing of the guide members 210 and the specifications of the material receiving fixture 300 without changing the material receiving device, so as to receive workpieces of various sizes and specifications. For example, in one embodiment, the bending equipment includes a material receiving device, and the material receiving device adopts a material receiving fixture of the first embodiment. The material receiving fixture and the bending equipment are connected to the bending machine through a connecting member 430, and the upper end of the guide member 210 is connected to the conveying and discharging end of the bending machine. When the bending equipment needs to produce and process workpieces of different specifications, the spacing of the positioning member 220 is adjusted by adjusting the bolt 111 to change the spacing of the guide members 210 and the specifications of the material receiving fixture 300, so as to receive workpieces of various sizes and specifications without changing the material receiving fixture.
