Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, specifically relating to a floating material mechanism for a rear transverse connecting rod bracket. Background Technology

[0002] Stamping is the primary process in automobile manufacturing, where metal sheets are processed into the required shapes using stamping machines and dies. The stamping process includes trimming, flanging, shaping, and punching. Impact pressure is applied to the sheet metal using a machine tool, causing plastic deformation to obtain parts with specific structural shapes. A floating material in stamping dies is an important structure used to ensure the smooth floating and positioning of parts during the stamping process, preventing deformation and wobbling. This floating material structure is widely used, not only improving the quality and production efficiency of stamped parts but also reducing die maintenance costs.

[0003] The rear transverse connecting rod bracket of the automobile has a symmetrical butterfly-shaped structure, with symmetrical left and right sides and a through hole in the middle connecting part. When the rear transverse connecting rod bracket is still a sheet material structure, it is fed to the punching die by the feeding structure, and holes are punched at specific positions on the sheet material. After the punching is completed, the sheet material is floated by the floating mechanism and then sent to the next process. The placement of the sheet material on the punching die is related to the punching position, so the positioning of the sheet material is very important; however, the punching die itself cannot position the sheet material. Utility Model Content

[0004] This utility model provides a floating material mechanism for a rear transverse connecting rod bracket. A positioning pin is set on the floating material structure. When the feeding structure conveys the material sheet, it inserts the original round hole in the middle of the rear transverse connecting rod bracket into the positioning pin. In this way, the positioning pin is used to position the material sheet, so that the placement position of the material sheet on the punching die is consistent each time, thus ensuring that the punching position on each material sheet is consistent.

[0017] Preferably, a positioning groove is formed in the first base, and a positioning post is provided in the positioning groove;

[0019] Preferably, the positioning rod has a semi-cylindrical structure.

[0021] The upper surface of the positioning post is also provided with the lower end of the positioning rod; the upper end of the positioning rod passes through the floating block, and there is no connection structure between the positioning rod and the floating block.

[0022] Preferably, an elastic element is provided on the upper surface of the positioning post, and the elastic element is sleeved on the outer periphery of the positioning insert;

[0023] The lower end of the elastic element is connected to the upper surface of the positioning post;

[0024] There is no connection between the upper end of the elastic element and the floating block.

[0025] Preferably, a portion of the floating block is configured as a transition section;

[0026] The width of the transition section gradually narrows.

[0027] The transition section integrally connects the front and rear parts of the floating block;

[0028] A support frame is provided directly below the transition section. When the floating block descends to its lowest point, the transition section is engaged with the support frame, which provides auxiliary support for the floating block.

[0029] Preferably, the lower surface of the support frame is disposed on the template;

[0030] The upper surface of the support frame is provided with two symmetrical vertical plates, and a frame groove is formed between the two vertical plates;

[0038] The top surface of the embedded groove is provided with a magnetic metal sheet, and the upper surface of the slider is provided with a magnetic sheet.

[0039] The beneficial effects of this utility model are:

[0040] This utility model provides a floating material mechanism for a rear transverse connecting rod support. A positioning rod passes through a floating material block. When the floating material block is at its lowest point, the positioning rod passes through the floating material block. When the feeding structure conveys the material sheet, the positioning rod passes through the round hole in the middle of the material sheet. At this time, the material sheet is located on the punching die, and due to the action of the positioning rod, the position of the material sheet is fixed. Under the punching of the punching die, the hole position is ensured to be fixed. The floating material block drives the material sheet to float to the highest position. At this time, the upper end of the positioning rod is flush with the upper surface of the floating material block, and the positioning rod does not affect the conveying of the material sheet.

[0041] An elastic element is sleeved on the outer periphery of the lower end of the positioning rod. The lower end of the elastic element is connected to the upper surface of the positioning post, and the upper end of the elastic element is not connected to the floating block. When the floating block is driven down by the telescopic post, the elastic element can prevent the floating block from directly impacting the upper end of the positioning post and causing impact to the positioning post, thereby damaging the positioning post structure.

[0042] A support frame is installed below the floating block. When the floating block descends to its lowest point, the transition part on the floating block is precisely engaged with the support frame, and the bottom of the transition part contacts the bottom surface of the support frame's groove. A pressure sensor is installed on the bottom surface of the groove. When the transition part of the floating block generates a pressure signal to the pressure sensor, it indicates that the floating block has descended to its lowest point. The pressure signal is fed into the PLC processor, and the PLC processor sends a control command to the control component of the telescopic column, so that the telescopic column automatically stops operating after the floating block descends to its lowest point.

[0043] Notches and grooves are made on the sides near the front and rear ends of the floating material block. Sliding blocks are installed in the notches and grooves and can move up and down. When the sliding blocks are moved up, the upper surface of the sliding blocks protrudes from the upper surface of the floating material block. At this time, the sliding blocks on both sides can block the material sheet on both sides of the notch of the rear transverse connecting rod support, further preventing the material sheet from shifting.

Detailed Implementation

[0056] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0057] Example 1

[0058] A floating mechanism for a rear transverse connecting rod support includes: a floating block 1, a drive assembly, and a positioning rod 501;

[0059] like Figure 1 As shown, the floating block 1 is positioned in the center of the template; the entire floating mechanism is located near the feeding side of the template.

[0060] The floating block 1 is long and extends from the feed side of the template to the punching mold and beyond the punching mold; a driving component is set below the floating block 1. Under the action of the driving component, the floating block 1 can lift the floating material and lower it back to its original position after the floating material is lifted.

[0061] like Figure 3 As shown, the aforementioned drive component is configured as a telescopic column 4. The telescopic column 4 can be a hydraulic telescopic column or a pneumatic telescopic column. The extension or retraction of the telescopic column 4 is driven and controlled by the telescopic column control component. Whether it is a pneumatic telescopic column or a hydraulic telescopic column, its own components and their respective control components are existing technologies known to those skilled in the art, and will not be described in detail here.

[0062] A first base 2 and a second base 3 are respectively set near both ends of the floating material block 1 and below the floating material block 1. The bottom surfaces of the first base 2 and the second base 3 are both set on the template. Telescopic column grooves are opened in the first base 2 and the second base 3. Telescopic columns 4 are set in the telescopic column grooves in both sets of bases. The base end of the telescopic column 4 is set in the telescopic column groove, and the telescopic end of the telescopic column 4 is located outside the telescopic column groove. The telescopic ends of the two sets of telescopic columns 4 are respectively connected to the bottom near both ends of the floating material block 1.

[0063] After the sheet material is fed in, it is sequentially conveyed between the dies of each process by the conveying structure. The aforementioned conveying structure is existing technology of existing automotive parts stamping machines. This utility model does not make any technical improvements to the conveying structure, so it will not be described in detail. The conveying structure delivers the sheet material to the punching die. The machine presses down to apply pressure to the sheet material, and with the cooperation of the machine and the punching die, a hole is punched in the sheet material. The position of the sheet material on the punching die determines the position of the hole on the sheet material. The punching die itself does not have the function of positioning the sheet material.

[0064] Therefore, as Figure 3 As shown, in this embodiment, a positioning rod 501 is provided below the floating block 1. When the floating block 1 is at its lowest position, the upper end of the positioning rod 501 passes through the upper surface of the floating block 1; when the floating block 1 is at its highest position, the uppermost end of the positioning rod 501 is flush with the upper surface of the floating block 1; there is no connecting structure between the positioning rod 501 and the floating block 1, and the positioning rod 501 will not affect the movement of the floating block 1. The floating block 1 can be freely raised and lowered relative to the positioning rod 501.

[0065] The positioning rod 501 is configured as follows: a positioning groove is opened in the first base 2, and a positioning post 5 is set in the positioning groove; the upper end of the positioning post 5 extends beyond the positioning groove, and the lower end of the positioning rod 501 is connected to the upper surface of the positioning post 5; the upper end of the positioning rod 501 passes through the floating block 1; the two sides of the positioning rod 501 are the punching molds.

[0066] When the floating block 1 is at its lowest position, the material sheet is conveyed from the feed side to the positioning rod 501; as Figure 9As shown, a round hole is made in the middle of the material sheet of the rear transverse connecting rod bracket. The round hole is inserted into the positioning rod 501, so that the material sheet and the positioning rod 501 maintain a fixed positional relationship. At this time, the material sheet is exactly on the punching mold. Under the action of the positioning rod 501, the material sheet and the punching mold always maintain a fixed positional relationship, which can ensure that the hole position on each material sheet is consistent. After the punching is completed, the floating block 1 floats the material sheet. When the floating block 1 floats to the highest position, the upper end of the positioning rod 501 is flush with the upper surface of the floating block 1. At this time, the material sheet can be normally conveyed to the next process.

[0067] As a preferred embodiment, the positioning rod 501 is configured as a semi-cylindrical structure, which makes it easier to pass the round hole on the material sheet through the positioning rod 501.

[0068] like Figure 3 As shown, a positioning groove is also opened on the second base 3, and a positioning post 5 is set in the positioning groove;

[0069] The lower end of the positioning rod 501 is also provided on the upper surface of the positioning column 5; the upper end of the positioning rod 501 passes through the floating block 1 and there is no connection structure between it and the floating block 1; the function of the positioning rod 501 at the second base 3 is that when feeding material, the material piece can be directly placed on the positioning rod 501 at the second base 3, and the round hole on the material piece can be inserted into the positioning rod 501 at this location; the distance between the positioning rods 501 at the two sets of bases is set as the conveying distance of the fixed step distance of the conveying structure, so that the material piece can be positioned after feeding, and after conveying the fixed step distance, the material piece can be conveyed to the positioning rod 501 at the first base 2;

[0070] like Figure 3 As shown, one part of the floating block 1 is set as a transition part 104; the width of the transition part 104 gradually narrows; the transition part 104 integrally connects the front and rear parts of the floating block 1.

[0071] A support frame 6 is installed directly below the transition section 104, with the bottom surface of the support frame 6 resting on the template; for example... Figure 5 As shown, two symmetrical vertical plates are provided on the upper surface of the support frame 6, and a support groove 601 is formed between the two vertical plates; when the floating block 1 descends to the lowest point, the transition part 104 is just locked in the support groove 601 on the support frame 6, and the support frame 6 is used to provide auxiliary support for the floating block 1.

[0072] Example 2

[0073] Based on Embodiment 1, in Embodiment 1, if the descent position of the float block 1 is not controlled in time when it is driven to descend by the telescopic column 4, the float block 1 may damage the upper end of the positioning column 5 set in the two sets of bases under long-term impact force, which may cause the positioning column 5 to tilt, thereby affecting the upright state of the positioning rod 501. If the upright state of the positioning rod 501 is damaged, it will affect the normal lifting and lowering of the float block 1.

[0074] like Figure 6 As shown, in this embodiment, an elastic element 502 is provided on the upper surface of the positioning post 5. The elastic element 502 is a spring and is sleeved on the lower outer periphery near the positioning rod 501. The lower end of the elastic element 502 is connected to the upper surface of the positioning post 5. There is no connection between the upper end of the elastic element 502 and the floating block 1.

[0075] Due to the presence of the elastic element 502, when the floating block 1 descends, it can avoid directly impacting the upper end of the positioning post 5.

[0076] Example 3

[0077] Based on Example 1, in Example 1, how to accurately identify whether the floating block 1 has fallen to the lowest position and control the floating block 1 to stop falling in time;

[0078] like Figure 5 As shown, in this embodiment, a pressure sensor 7 is provided at the bottom of the support slot 601 of the support frame 6; the pressure sensor 7 is communicatively connected to the PLC processor, and the PLC processor is communicatively connected to the control component of the telescopic column 4.

[0079] When the float block 1 descends to the transition step and is just stuck in the slot 601, the float block 1 will generate a pressure sensing signal to the pressure sensor 7. The pressure sensing signal is fed into the PLC processor. When the PLC receives the pressure sensing signal, it means that the float block 1 has descended to the lowest position. The PLC will send a control command to the control component of the telescopic column 4 to stop the telescopic column 4 from operating and the float block 1 will no longer descend.

[0080] Example 4

[0081] Based on Example 1, if the inner diameter of the circular hole in the middle of the sheet is larger than the outer diameter of the positioning rod 501, then when the sheet is inserted into the positioning rod 501 through the circular hole, the sheet will still undergo a slight displacement relative to the positioning rod 501.

[0082] like Figure 7As shown, in this embodiment, notches 102 are provided near the front and rear ends of the floating block 1 and on the side of the floating block 1; an embedded sliding groove 103 is provided on the bottom surface of the notch 102; and a sliding stop 9 is provided in the notch 102 that can move up and down.

[0083] The connection structure between the sliding block 9 and the notch 102 is as follows: a slider 901 is provided on the back of the sliding block 9, and the cross-section of the slider 901 is a combination of a rectangle and a trapezoid; the slider 901 is movably disposed in the embedded groove 103; the structural shape of the embedded groove 103 matches the slider 901, and the slider 901 will not come out of the embedded groove 103; there is an interference fit between the slider 901 and the embedded groove 103, pushing the sliding block 9 upward so that the upper surface of the sliding block 9 exceeds the upper surface of the floating block 1; so that the sliding blocks 9 on both sides are just locked in place as shown in the figure. Figure 9 Both sides of the notch in the sheet; thus, under the limiting action of the sliding block 9, the sheet will not move;

[0084] In a preferred embodiment, to ensure that the sliding block 9 can remain locked in the upward position after being pushed up and will not easily slide down, a magnetic metal sheet is provided on the top surface of the embedded groove 103, and a magnetic sheet 902 is provided on the upper surface of the slider 901. In this way, when the sliding block 9 is pushed up, when the upper surface of the slider 901 contacts the top surface of the embedded groove 103, the magnetic metal sheet and the magnetic sheet 902 are attracted to each other, and the upward state of the sliding block 9 is kept in place by magnetic attraction and will not easily slide down.
