Description

Technical Field

[0001] This utility model belongs to the field of stamping technology, and in particular relates to a stamping and shaping device. Background Technology

[0002] In the current stamping process of parts, after the parts are stamped, there is usually residual stress deformation inside the parts, and the bending structure of the stamped parts does not meet the requirements. Therefore, the parts need to be shaped afterward. This involves placing the parts in the contour groove of the lower die and installing a shaping protrusion with a contour structure in the upper die. The shaping protrusion and the contour groove of the lower die continuously squeeze the parts to complete the shaping process.

[0003] However, when the structure of the part is complex and irregular, especially when it is a curved or irregularly shaped part, the structure of the contouring groove in the lower die and the shaping protrusion in the upper die is more complex and the processing cost is higher. When the irregular part fits closely with the contouring groove, it can meet the control of the shaping accuracy of the irregular part to a certain extent, but it is not convenient for the irregular part to be put into and taken out of the contouring groove. When there is a gap between the irregular part and the contouring groove, it is convenient for the irregular part to be put into and taken out, but the shaping accuracy cannot be guaranteed.

[0004] In the actual process of shaping irregularly shaped parts, the following problems may be encountered: Figure 16 The irregularly shaped part shown is part 1, which requires shaping. It has a symmetrical structure, including a long, plate-like part body 11 and a protruding plate 12 integrally formed along the length of the upper end face of the part body 11. The width of the protruding plate 12 is smaller than the width of the part body 11. The two end faces of the middle portion of the protruding plate 12 extend outwards to form upwardly curved connecting portions 13. An arc-shaped protrusion 14 is integrally formed on the outer arc surface of the connecting portion. The upper end faces of the connecting portion 13 and the arc-shaped protrusion 14 are planar. Furthermore, a part groove 15 is formed on the part body 11 near the connecting portion 13, extending from the outer end face of the part body 11 to the part protruding plate 12. This part needs to maintain the curvature of the connecting portion 13, therefore, the connecting portion 13 needs to be shaped.

[0005] Therefore, in view of the above-mentioned technical problems and the actual forming characteristics, it is urgent to design a stamping forming device with high forming accuracy and easy handling of parts. Utility Model Content

[0006] To address the technical problems existing in the prior art, this application provides a stamping forming device with high part forming accuracy and easy part handling.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A stamping and forming device includes a base and a stamping seat located above the base. A guide block with a guide groove is fixedly connected to the base, and a positioning component is disposed in the guide groove. The positioning component includes a fixing block fixedly connected to the guide groove, a lower contour block embedded in the fixing block, lower wedges slidably disposed in guide grooves on both sides of the lower contour block, a positioning spring embedded in the lower wedge with one end abutting against the fixing block, and a positioning strip disposed on the lower wedge. A forming component is fixedly connected to the stamping seat.

When forming a part, the part is placed in the lower contour block, and the stamping seat moves the upper wedge block downward so that the lower wedge block moves the positioning strip to abut against the part, and the upper contour block presses against the part to form it.

[0009] Preferably, a pressure plate is fixedly embedded on the lower wedge block, and the positioning strip is fixedly embedded in the pressure plate. When the lower wedge block moves, it can drive the pressure plate and the positioning strip to move.

[0010] Preferably, a pressure plate groove is formed on the lower end face of the pressure plate, and a pressure plate limiting groove is formed in the pressure plate groove on the side of the pressure plate away from the fixing block; a limiting protrusion matching the pressure plate limiting groove is formed on the upper end face of the positioning strip, the positioning strip is embedded in the pressure plate groove and the limiting protrusion is embedded in the pressure plate limiting groove, and one end face of the positioning strip with the limiting protrusion abuts against the lower wedge block.

[0011] Preferably, a plurality of positioning posts are fixedly embedded vertically downward on the mounting plate, and a positioning hole matching the positioning post is opened on the upper end face of the guide block, and the positioning post can be inserted into the positioning hole.

[0012] Preferably, a connecting plate is fixedly connected to the lower end of the stamping seat, and a mounting plate is fixedly connected to the lower end face of the connecting plate. A slider is embedded in the mounting plate, and the upper contouring plate is embedded in the slider. The upper contouring block includes a floating contouring block that can be slidably locked in the slider and a fixed contouring block that is fixedly embedded in the slider. A positioning buffer assembly is provided in the connecting plate. The positioning buffer assembly includes a top block that can be slidably embedded in the connecting plate. The lower end face of the top block abuts against the upper end face of the floating contouring block. A screw is threadedly connected to the connecting plate above the top block. A compression spring is provided in the connecting plate between the screw and the top block. The floating contouring block can move upward after abutting the part to compress the compression spring.

[0013] Preferably, a limiting plate is fixedly connected to the upper end face of the slider, and the limiting plate is disposed below the connecting plate; a buffer spring is embedded in the lower end face of the connecting plate and the upper end face of the limiting plate opposite to it; the limiting plate and the slider are slidably embedded in the mounting plate; the limiting plate, the slider and the upper contour block can slide upward to compress the buffer spring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention uses the upper wedge to press the lower wedge, thereby causing the lower wedge to drive the positioning strip to position and fix part 1. After the upper wedge separates from the lower wedge, the positioning spring can move the lower wedge back to its original position under the action of elasticity, thereby releasing the positioning strip from part 1. Through the above structure, automatic clamping and loosening of the part can be realized, which is convenient for picking up and putting down the part. In addition, this invention achieves high-precision shaping of the part by setting a lower contour block and an upper contour block that match the part. By designing the lower contour block and the upper contour block as a split structure, it is convenient for processing and can further improve the shaping accuracy of the part.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0043] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0044] See appendix Figure 1 , 2 As shown in Figures 1 and 3, a stamping and forming device includes a positioning mechanism 2 located below and a stamping and forming mechanism 3 located above.

[0045] The positioning mechanism 2 includes a horizontally arranged base 21, a base plate 22 horizontally fixed to the upper surface of the base 21 by bolts, a guide block 23 with a guide groove 231 fixed to the base plate 22 by bolts, and a positioning component 24 disposed in the guide groove 231. The guide groove 231 has a convex structure and is opened along the length direction of the guide block 23, and four positioning holes 232 are opened on the upper surface of the guide block 23.

[0046] See Figure 4 , 5 As shown, the positioning component 24 includes a fixing block 241, a lower contour block 242, a lower wedge block 243, a positioning spring 244, a positioning strip 245, and a pressure plate 246. The fixing block 241 is fixedly connected to the guide groove 231 in the middle of the guide block 23 by bolts, and the lower contour block 242 is fixedly embedded in the fixing block 241.

[0047] See Figure 7As shown, the lower contour block 242 is a split structure, comprising a lower contour block 1 2421 located in the middle and lower contour blocks 2422 located on both sides of the lower contour block 1 2421. The upper inner side of the lower contour block 2422 is provided with a positioning groove 2423 with the same curvature as the arc protrusion 14 of part 1. The upper end face of the lower contour block 1 2421 is provided with a positioning groove 2424 along its length, and two positioning protrusions 2425 are provided on the upper end face of the lower contour block 1 2421 on one side of the positioning groove 2424.

[0048] See Figure 8 As shown, when part 1 is placed on the lower contour block 242, the outer arc surfaces of the two arc-shaped protrusions 14 of part 1 fit against the groove wall of the second positioning groove 2423, the part body 11 of part 1 is embedded in the first positioning groove 2424, and the two positioning protrusions 2425 are embedded in the part groove 15 of part 1.

[0049] It should be noted that, in order to shape the two parts 1 at the same time, two lower contour blocks 242 are provided on the fixing block 241.

[0050] In order to enable quick loading and unloading of part 1 on the lower contour block 242, and at the same time to align, position and clamp part 1 during shaping, in this embodiment, the positioning bar 245 can clamp and release part 1 under the drive of the lower wedge block 243.

[0051] See Figure 5 As shown, specifically, there are two lower wedges 243, each slidably disposed within the guide grooves 231 on both sides of the fixed block 241. The overall cross-section of the lower wedge 243 is a convex-shaped structure matching the guide grooves 231. That is, the lower wedge 243 includes a lower plate 2431 slidably engaged within the guide grooves 231, a boss 2432 integrally formed on the upper end face of the lower plate 2431, a boss inclined surface 2433 on the outer side of the boss 2432, and a boss groove 2434 on the upper end face of the boss 2432. The pressure plate 246 is fixedly connected to the bottom of the boss groove 2434 by bolts. The positioning strip 245 is fixedly embedded in the pressure plate 246 and can be driven by the lower wedges 243 to drive the pressure plate 246 to clamp and release the positioning strip 245.

[0052] See Figure 6As shown, in this embodiment, a pressure plate groove 2461 is provided on the lower end face of the pressure plate 246. In order to tighten the two arc-shaped protrusions 14 of a single part 1, each part 1 requires two sets of four positioning strips 245. Since in this embodiment, two parts 1 need to be shaped simultaneously, four pressure plate grooves 2461 are provided on each pressure plate 246. A pressure plate limiting groove 2462 is provided in each pressure plate groove 2461 on the side of the pressure plate 246 away from the fixing block 241. The pressure plate limiting groove 2462 extends from the end face of the pressure plate 246 to its inner side.

[0053] See Figure 7 As shown, a limiting protrusion 2451 matching the pressure plate limiting groove 2462 is provided on the upper end face of the positioning strip 245. The positioning strip 245 is embedded in the pressure plate groove 2461 and the limiting protrusion 2451 is embedded in the pressure plate limiting groove 2462. One end face of the positioning strip 245 with the limiting protrusion 2451 abuts against the vertical groove wall of the boss groove 2434 of the lower wedge block 243.

[0054] Each positioning strip 245 above the fixing block 241 has a positioning strip groove 2452 at its end that matches the outer arc surface of the connecting part 13. See [reference needed] Figure 8 As shown, the arc-shaped groove walls of the positioning grooves 2452 of each pair of opposing positioning strips 245 abut against the outer arc surfaces of the connecting portions 13 on both sides of the arc-shaped protrusion 14. When the end of the positioning groove 2452 is pressed against the two sides of the arc-shaped protrusion 14, the part 1 is fixed to facilitate shaping; when there is a gap between the end of the positioning groove 2452 and the two sides of the arc-shaped protrusion 14, the part 1 can be easily removed from the lower contour block 242.

[0055] See Figure 5 As shown, in order to enable the lower wedge block 243 to drive the pressure plate 246 to drive the positioning strip 245 to reciprocate, a horizontally arranged positioning spring 244 is fixedly embedded on the inner end face of the boss 2432 opposite to the vertical end face of the fixed block 241. One end of the positioning spring 244 on the outer side of the boss 2432 abuts against the fixed block 241. When the stamping and forming mechanism 3 abuts against the lower wedge block 243 and pushes the two opposing lower wedge blocks 243 to move towards each other, the positioning strip 245 can be driven to press against the part 1. When the stamping and forming mechanism 3 disengages from the lower wedge block 243, the two opposing lower wedge blocks 243 move away from each other under the elastic force of the positioning spring 244, thereby causing the positioning strip 245 to disengage from the part 1.

[0056] See Figure 9 , 10As shown, the stamping and forming mechanism 3 includes a stamping seat 31 located above the base 21. A forming component is fixedly connected to the stamping seat 31. The forming component includes a connecting plate 32 fixedly mounted on the lower end face of the stamping seat 31 by bolts, a mounting plate 33 fixedly mounted on the lower end face of the connecting plate 32 by bolts, a slider 39 embedded in the mounting plate 33, an upper contour block 34 embedded in the slider 39, and upper wedge blocks 35 that match the lower wedge block 243 and are fixedly connected to the mounting plate 33 on both sides of the upper contour block 34 by bolts. The inclined surface of the upper wedge 35 is formed on its inner end face. The inclined surface of the upper wedge 35 is opposite to the inclined surface of the boss 2433. That is, when the upper wedge 35 moves down, the inclined surface of the upper wedge 35 gradually comes into contact with the inclined surface of the boss 2433, pushing the lower wedge 243 toward the fixed block 241. After the inclined surface of the upper wedge 35 is in complete contact with the inclined surface of the boss 2433, the inclined surface of the upper wedge 35 comes into contact with the end face of the lower plate 2431. At this time, the lower wedge 243 no longer moves toward the fixed block 241.

[0057] To improve the shaping accuracy, four positioning posts 36 are vertically and downwardly embedded on the mounting plate 33, and the positioning posts 36 can be inserted into the corresponding positioning holes 232.

[0058] See Figure 13 , 14 As shown, the upper contour block 34 is a split structure, which includes a floating contour block 341 located on both sides for pressing the connecting part 13 and the upper surface of the arc-shaped protrusion 14, two upper contour blocks 342 located inside the floating contour block 341 and symmetrically arranged, two upper contour blocks 343 located inside the upper contour blocks 342 and symmetrically arranged, and an upper contour block 344 located between the two upper contour blocks 343. The upper contour blocks 342, 343 and 444 can be fixedly embedded in the mounting plate 33, so the three of them are fixed contour blocks. The lower end face of the upper contour block 2 342 is an arc surface structure that matches the inner arc surface of the connecting part 13. When shaping part 1, the lower end face of the upper contour block 2 342 fits against the inner arc surface of the connecting part 13. The lower end faces of the two upper contour blocks 343 can respectively abut against the upper end face of the part body 11 on both sides of the convex plate 12, and the lower end face of the upper contour block 4 344 can abut against the upper end face of the convex plate 12.

[0059] See Figure 11 , 12As shown, since the main function is to shape the curvature of the connecting part 13 of part 1, in order to achieve longitudinal positioning of part 1, the floating contour block 341 needs to float and press part 1. Therefore, in this embodiment, a positioning buffer assembly 37 is provided in the connecting plate 32, and a limiting plate 38 is fixedly connected to the upper end face of the slider 39 by bolts. The limiting plate 38 is located below the connecting plate 32. Four coaxially arranged connecting plate through holes and limiting plate through holes are respectively opened on the connecting plate 32 and the limiting plate 38. The inner diameter of the limiting plate through hole is smaller than the inner diameter of the connecting plate through hole.

[0060] The positioning buffer assembly 37 includes a top block 371 slidably embedded in the through holes of the connecting plate and the limiting plate. The upper part of the top block 371 slidably passes through the through hole of the connecting plate, and its lower part slidably passes through the through hole of the limiting plate and abuts against the upper end face of the floating contour block 341. The upper outer diameter of the top block 371 is larger than its lower outer diameter. A screw 372 is threaded into the through hole of the connecting plate above the top block 371. A compression spring 373 is vertically arranged in the through hole of the connecting plate between the screw 372 and the top block 371. After the floating contour block 341 abuts against the part 1, it can move upward to compress the compression spring 373. That is, when the floating contour block 341 is not abutting against the part, it moves downward under the action of gravity. At this time, there is a gap between the upper end face of the floating contour block 341 and the lower end face of the limiting plate 38. In this embodiment, to prevent the floating contour block 341 from detaching from the slider 39 under the action of gravity, a countersunk hole 391 is provided on the upper end face of the slider 39, and a blocking protrusion 3411 is provided on the outer side of the floating contour block 341. The countersunk hole 391 can block the blocking protrusion 3411, thereby preventing the floating contour block 341 from detaching from the lower opening of the countersunk hole 391. The floating contour block 341 can be slidably disposed in the countersunk hole 391.

[0061] Furthermore, to achieve buffering of the fixed contour blocks formed by upper contour block 2 342, upper contour block 343, and upper contour block 4 344, two buffer springs 374 are embedded in the lower end face of the connecting plate 32 and the upper end face of the opposite limiting plate 38. The limiting plate 38 and the slider 39 are slidably embedded in the mounting plate 33. Under the action of gravity, the limiting plate 38 and the slider 39 move downward, thereby stretching the buffer springs 374 and leaving a gap between the upper end face of the limiting plate 38 and the lower end face of the connecting plate 32. When upper contour block 2 342, upper contour block 343, and upper contour block 4 344 press against part 1, the limiting plate 38 and the slider 39 slide upward to compress the buffer springs 374.

[0062] It should be noted that in this embodiment, two parts 1 need to be shaped at the same time, so the upper contour block 34 and the corresponding positioning buffer assembly 37 are also provided in two sets.

[0063] The working principle and process of this embodiment are as follows:

[0064] like Figure 15 As shown, this utility model can be used in conjunction with other components to improve processing efficiency. For example, a support platform 4 can be set up, an existing stamping equipment 5 can be set up on the support platform 4, a positioning mechanism 2 can be fixedly installed on the mounting base 51 of the stamping equipment 5, and a stamping and shaping mechanism 3 can be fixedly installed on the stamping part 52 of the stamping equipment 5. In addition, an existing conveying device 6 can be set up on the mounting base 51 of the stamping equipment 5, and a parts collection box 7 can be set up on the support platform 4 on one side of the conveying device 6. The conveying device 6 can transfer the part 1 to be shaped to the lower contour block 242, and can transfer the shaped part 1 from the lower contour block 242 to the parts collection box 7.

[0065] 1. In the initial state, under the elastic force of the positioning spring 244, the two lower wedges 243 in each group drive the positioning strips 245 to move away from each other, thereby increasing the distance between the two opposing positioning strips 245, so as to place part 1 between the two opposing positioning strips 245;

[0066] 2. Then, the conveying device 6 picks up the part 1 to be shaped from the existing material tray (not shown in the figure) and transfers it into the lower contour block 242, i.e. Figure 8 As shown, the outer arc surfaces of the two arc-shaped protrusions 14 of part 1 are in contact with the groove wall of the second positioning groove 2423. The part body 11 of part 1 is embedded in the first positioning groove 2424, and the two positioning protrusions 2425 are embedded in the part groove 15 of part 1. The arc-shaped protrusions 14 are located between the ends of the two opposing positioning strips 245, and the outer arc surfaces of the connecting parts 13 on both sides of the arc-shaped protrusions 14 are in contact with the positioning strip groove 2452.

[0067] 3. The stamping equipment 5 drives the stamping and forming mechanism 3 to move downward. First, the positioning pin 36 is inserted into the positioning hole 232 on the guide block 23 to position the stamping and forming mechanism 3. Then, the inclined surfaces of the upper wedge 35 and the lower wedge 243 abut against each other, thereby pushing the lower wedge 243 to move inward until the inclined surface of the upper wedge 35 abuts against the vertical end face of the lower plate 2431. At this time, the lower wedge 243 stops moving. At this time, the two opposing lower wedges 243 have respectively driven the two opposing positioning strips 245 to clamp the part 1. Then, the floating contour block 341 presses against the part. The upper end face of the connecting part 13 and the arc-shaped protrusion 14, the stamping and shaping mechanism 3 continues to move downward, and the pressing spring 373 is compressed; then the upper contour block 2 342, the upper contour block 343, and the upper contour block 4 344 respectively press the inner arc surface of the connecting part 13 of the part 1, the upper end face of the part body 11 on both sides of the protrusion 12, and the upper end face of the protrusion 12. The stamping and shaping mechanism 3 continues to move downward, and the slider 39 and the limiting plate 38 move upward to compress the buffer spring 374; the stamping and shaping mechanism 3 stops moving downward and maintains this position for a certain period of time to achieve the shaping of the part 1;

[0068] 4. The stamping equipment 5 drives the stamping and forming mechanism 3 to rise to complete the forming of part 1. As the upper wedge 35 disengages from the lower wedge 243, the positioning strip 245, pressure plate 246 and lower wedge 243 move away from each other under the elastic force of the positioning spring 244, thereby causing the two opposing positioning strips 245 to release part 1. Then the conveying equipment 6 transfers the formed part 1 to the part collection box 7.

[0069] 5. By repeating the above process, the batch shaping of part 1 can be achieved.

[0070] It should be noted that the key points to be protected by this stamping and forming device are the structures of the positioning mechanism 2 and the stamping and forming mechanism 3. The controller, support platform 4, stamping equipment 5, conveying equipment 6, parts collection box 7 and other structures used in conjunction with this stamping and forming device are all existing technologies and will not be described in detail here.

[0071] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
