Description

Technical Field

[0001] This application relates to the technical field of steel plate processing, and particularly relates to a steel plate stamping and forming device. Background Art

[0002] In industrial production, there is a wide range of application requirements for stamping steel plates into cylindrical shapes. The cylindrical steel plate structure is indispensable in many fields. For example, in a pipeline system, the cylindrical steel plate can be used as the main body of the pipeline for transporting liquids and gases. With its closed and continuous structure, it ensures the stable transmission of the medium.

[0003] The original steel plate stamping and forming device includes a support frame, a hydraulic telescopic rod, an upper die, a stamping die, and a lower die. The hydraulic telescopic rod is arranged at the top of the support frame, and the extending shaft of the hydraulic telescopic rod is connected to the upper die. The stamping die is elastically arranged in the middle of the support frame, and the lower die is arranged at the bottom of the support frame. During use, the relevant operator places the steel plate on the lower die. The hydraulic telescopic rod extends and abuts against the stamping die. The stamping die punches the middle part of the steel plate into the lower die, making one end of the steel plate semi-circular. The relevant operator then slews the semi-circular end of the steel plate over the top of the stamping die, and continues to control the hydraulic telescopic rod to extend and abut against the stamping die. The upper die squeezes and limits the semi-circular end of the stamped steel plate, and the stamping die punches the two end parts of the steel plate into the lower die, making the two ends of the steel plate gradually deform into a circular shape in the semi-circular groove of the lower die, thereby completing the stamping and forming of the steel plate.

[0004] However, in the above stamping method, the following problems exist:

[0005] 1. During the process of steel plate forming, it is necessary to adjust the position of the steel plate multiple times, which is time-consuming and laborious, thus affecting the stamping and forming efficiency of the steel plate.

[0006] 2. After the stamped steel plate (in a cylindrical shape) is taken out, the steel plate (the steel plate has a certain elasticity) restores its elastic deformation, which will cause the separation of the two end parts of the steel plate. When processing the cylindrical steel plate in the next process, it is necessary to use a separate fixture to tighten the two end parts of the steel plate before proceeding with the operation, which makes the subsequent operation cumbersome and affects the processing efficiency of the steel plate.

[0034] The following details the embodiments of the present application. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0035] The following describes the steel plate stamping and forming device of the embodiments of the present application with reference to the drawings.

[0036] As Figures 1 - 12 shown, the steel plate stamping and forming device of the embodiments of the present application may include a workbench 1, two U-shaped stamping components 2, a diamond stamping component 3, and a circular stamping component 4.

[0037] Among them, the workbench 1 is provided with a U-shaped stamping groove 11, a rectangular stamping groove 12, and a forming stamping groove 13 from top to bottom, and they are connected in sequence.

[0038] It should be noted that the U-shaped stamping groove 11 described in this example is similar in shape to a U shape. For further reference,Figure 4 The shape of the U-shaped stamping groove 11 in

[0039] It can be understood that a U-shaped stamping groove 11 is provided at the top of the workbench 1, a rectangular stamping groove 12 is provided in the middle, and a forming stamping groove 13 is provided at the bottom. The U-shaped stamping groove 11 communicates with the rectangular stamping groove 12, and the rectangular stamping groove 12 communicates with the forming stamping groove 13.

[0040] It should be noted that both ends of the U-shaped stamping groove 11 described in this example are arc-shaped. The two U-shaped stamping components 2 respectively stamp the two ends of the steel plate and are respectively in stamping cooperation with the arc-shaped ends of the corresponding U-shaped stamping grooves 11, so that the flat steel plate is stamped into a U shape.

[0041] It should be noted that the rectangular stamping groove 12 described in this example is provided in the middle of the U-shaped stamping groove 11, and the width of the rectangular stamping groove 12 is smaller than the width of the U-shaped stamping groove 11. The width of the steel plate that has not been processed into a U shape is greater than the width of the U-shaped stamping groove 11. The rectangular stamping groove 12 is in stamping cooperation with the diamond-shaped stamping component 3. When working, the diamond-shaped stamping component 3 stamps the middle of the U-shaped steel plate, and the part of the diamond-shaped stamping component 3 that abuts against the middle of the U-shaped steel plate gradually deforms, so that the U-shaped steel plate is limited and stamped in the rectangular stamping groove 12 to form a diamond shape (for the shape of the diamond-shaped steel plate, refer to Figure 9 ), that is, the diamond-shaped stamping component 3 stamps the middle of the U-shaped steel plate with both ends upturned and moves into the rectangular stamping groove 12. In order for the U-shaped steel plate to adapt to the width of the rectangular stamping groove 12, the two sides of the middle of the U-shaped steel plate are bent and deformed, and the inner buckets at the ends of the U-shaped steel plate with both ends upturned move towards each other (that is, move towards each other with both ends approaching), so that the steel plate is stamped into a diamond shape.

[0042] A through groove 14 is also provided on the workbench 1. One side of the through groove 14 communicates with the U-shaped stamping groove 11, the rectangular stamping groove 12 and the forming stamping groove 13 respectively. The other side of the through groove 14 penetrates through the workbench 1. A toothed plate 15 is provided on the workbench 1. The toothed plate 15 is located on one side of the bottom of the through groove 14. The two U-shaped stamping components 2 are respectively arranged on the support frame 10 of the workbench 1.

[0043] It should be noted that the through groove 14 described in this embodiment is provided on one side edge of the workbench 1. Through the setting of the through groove 14, the downward movement effect of one end of the variable pitch abutting mechanism 31 in the diamond-shaped stamping component 3 is ensured.

[0044] It should be noted that the position where the toothed plate 15 meshes and rotates with the gear 313 is above the center point of the second semi-circular die 42 in the circular stamping component 4. The further detailed position is adjusted according to the actual situation and will not be described in detail here, so as to ensure that the diamond-shaped steel plate can be rotated to the appropriate stamping position between the first semi-circular die 41 and the second semi-circular die 42 in the circular stamping component 4.

[0045] The diamond stamping assembly 3 may include a variable pitch abutting mechanism 31 and two middle stamping parts 30.

[0046] Among them, the two middle stamping parts 30 are respectively arranged on the support frame 10.

[0047] It can be understood that through the arrangement of the two middle stamping parts 30, the stable stamping effect of the variable pitch abutting mechanism 31 can be ensured.

[0048] One end of the variable pitch abutting mechanism 31 is located above the rectangular stamping groove 12, the other end of the variable pitch abutting mechanism 31 is located above the through groove 14, and one ends of the two middle stamping parts 30 are respectively rotatably connected to the other end of the variable pitch abutting mechanism 31. A gear 313 arranged at the other end of the variable pitch abutting mechanism 31 is telescopically meshed and rotatably connected with a toothed plate 15.

[0049] It should be noted that in this embodiment, one end of the variable pitch abutting mechanism 31 described is the stamping end, and the other end of the variable pitch abutting mechanism 31 is the control end. Through the arrangement of the stamping end and the control end, when the variable pitch abutting mechanism 31 stamps the U-shaped steel plate into a diamond shape, both ends of the diamond-shaped steel plate can abut (that is, the diamond-shaped steel plate can surround and cover the stamping end), and after the diamond-shaped steel plate is stamped into a circular shape by the circular stamping assembly 4, the relevant operators can directly remove the formed circular steel plate, thus facilitating the blanking of the formed steel plate.

[0050] It should be noted that the gear 313 described in this embodiment is controllably connected to the other end (i.e., the control end) of the variable pitch mechanism. Thus, when the gear 313 meshes and rotates with the toothed plate 15, the rotation of the gear 313 drives the variable pitch mechanism to rotate, and can drive the diamond-shaped steel plate to rotate to a specified position, thus facilitating the stamping and forming of the diamond-shaped steel plate by the circular stamping assembly 4.

[0051] It should be noted that one end (i.e., the stamping end) of the variable pitch abutting mechanism 31 described in this embodiment can contract during stamping and extend after stamping, so that the variable pitch mechanism can abut the steel plate formed into a diamond shape, and the diamond-shaped steel plate can rotate following the variable pitch abutting mechanism 31, thus ensuring the stamping and forming of the diamond-shaped steel plate by the circular stamping assembly 4.

[0052] It should be noted that the gear 313 provided at the other end of the variable pitch abutting mechanism 31 described in this embodiment is telescopically meshed and rotationally connected with the toothed plate 15. Telescopically meshed and rotationally connected means that two middle stampings 30 control the variable pitch abutting mechanism 31 telescopically. When the gear 313 extends to the toothed plate 15 and continues to extend, the gear 313 meshes with the toothed plate 15, and the gear 313 rotates. In addition, when the two middle stampings 30 need to contract after extending to a specified position, the gear 313 meshes with the toothed plate 15, and the gear 313 rotates in the reverse direction, thereby realizing the telescopic meshing and rotational connection between the gear 313 and the toothed plate 15.

[0053] The circular stamping assembly 4 is arranged on the workbench 1 and is located in the forming stamping groove 13.

[0054] It should be noted that a rotating groove 130 is communicated with the forming stamping groove 13 described in this embodiment, so as to facilitate the reversal of the stamping direction of the diamond-shaped steel plate.

[0055] In the embodiment of the present application, the circular stamping assembly 4 is used to continue stamping the steel plate stamped into a diamond shape and stamp it into a circular shape.

[0056] It should be noted that during the operation of the circular stamping assembly 4 described in this embodiment, the diamond-shaped steel plate is forced to be extruded into the circular cavity in the circular stamping assembly 4 (that is, the circular cavity formed by the first semi-circular die 41 and the second semi-circular die 42 in the circular stamping assembly 4) under high pressure. After plastic deformation, the steel plate fits the die contour, thereby stamping the diamond-shaped steel plate into a circular shape. In addition, stamping the steel plate into a diamond shape first has the effect of pre-stretching the steel plate, making the diamond the intermediate state of the steel plate deformation, and performing step-by-step deformation (that is, U-shaped - diamond-shaped - circular), thereby avoiding the springback of the steel plate directly formed into a circular shape and making the two ends of the steel plate in an effective abutting state.

[0057] Specifically, during the actual operation process, relevant operators first place the steel plate at the specified position on the workbench 1, start the device, and the controller (not shown in the figure) controls the two U-shaped stamping assemblies 2 to work and extend, and stamp the steel plate into the U-shaped stamping groove 11, making the steel plate stamped into a U-shaped. During the extension process of the two U-shaped stamping assemblies 2, the two middle stampings 30 of the diamond stamping assembly 3 extend synchronously, so that the variable pitch abutting mechanism 31 is in a certain abutting state with the steel plate, thereby playing the role of abutting and limiting the steel plate.

[0058] The controller controls the two U-shaped stamping components 2 to contract, controls the two middle stamping parts 30 in the diamond-shaped stamping component 3 to continue to extend, and drives the variable-spacing abutting mechanism 31 to continue to extend, so that the middle part of the steel plate is gradually deformed and gradually moves into the rectangular stamping groove 12, so that the two ends of the U-shaped steel plate are gradually bent towards each other to move inward, and follow the middle part of the U-shaped steel plate into the rectangular stamping groove 12 (at this time, the stamping end of the variable-spacing abutting mechanism 31 is in a contracted state), so that the U-shaped steel plate is stamped into a diamond shape, and the diamond-shaped steel plate surrounds and covers one end (i.e., the stamping end) of the variable-spacing abutting mechanism 31. The controller continues to control the two middle stamping parts 30 to extend, so that the variable-spacing abutting mechanism 31 and one end of the diamond-shaped steel plate gradually enter the forming stamping groove 13 (at this time, the stamping end of the variable-spacing abutting mechanism 31 is in an extended state and abuts against the diamond-shaped steel plate), and the gear 313 meshes with the toothed plate 15 and rotates. The rotation of the gear 313 drives the variable-spacing abutting mechanism 31 to rotate, and drives the diamond-shaped steel plate to rotate to a suitable stamping position (that is, the position where the circular stamping component 4 can effectively stamp the diamond-shaped steel plate into a circular shape). The controller controls the circular stamping component 4 to do work, stamps the diamond-shaped steel plate into a circular shape, and the two ends of the circular steel plate are in an abutting state. The relevant operator removes the formed circular steel plate, and each component returns to the initial position, thus completing one forming of the steel plate.

[0059] In an embodiment of the present application, as Figure 1 and Figure 6 shown, the variable-spacing abutting mechanism 31 may further include a control rod 310, a connecting block 311 and a second stamping block 312.

[0060] Wherein, one end of the control rod 310 is connected to the connecting block 311, one ends of the two middle stamping parts 30 are respectively rotatably connected to the control rod 310, and the control rod 310 is located above the through groove 14. The gear 313 is arranged at the other end of the control rod 310. One end of the second stamping block 312 is elastically telescopically connected to the connecting block 311, and the second stamping block 312 is located above the rectangular stamping groove 12.

[0061] It should be noted that the width of the second stamping block 312 described in this embodiment is smaller than the width of the rectangular stamping groove 12, so as to ensure the effect of stamping the U-shaped steel plate into a diamond shape in the rectangular stamping groove 12.

[0062] It should be noted that the elastic telescopic connection of one end of the second stamping block 312 to the connecting block 311 described in this embodiment means that one end of the second stamping block 312 is slidably connected to a sliding groove (not shown in the figure) opened inside the connecting block 311, and a spring 3111 is arranged in the sliding groove. One end of the spring 3111 is connected to the second stamping block 312, and the other end of the spring 3111 is connected to the connecting block 311.

[0063] It can be understood that the control rod 310 can slide within the through slot 14, the connecting block 311 and the second stamping block 312 can slide within the rectangular stamping slot 12, and the widths of the connecting block 311 and the second stamping block 312 are smaller than the width of the rectangular stamping slot 12, thereby ensuring the forming effect of the diamond-shaped steel plate.

[0064] In an embodiment of the present application, as Figure 1 and Figure 6 shown, the middle stamping member 30 may include a second hydraulic telescopic rod 300 and a limiting sleeve 301.

[0065] Among them, the second hydraulic telescopic rod 300 is arranged on the support frame 10, the extending shaft of the second hydraulic telescopic rod 300 is connected to the limiting sleeve 301, the limiting sleeve 301 is sleeved on the control rod 310, and the control rod 310 can rotate.

[0066] It should be noted that the width of the limiting sleeve 301 described in this example is not limited and is adjusted according to the actual situation, thereby ensuring the stable control of the variable-distance abutting mechanism 31 by the second hydraulic telescopic rod 300.

[0067] In an embodiment of the present application, as Figure 1 and Figure 4 shown, the U-shaped stamping assembly 2 may include a first hydraulic telescopic rod 20 and a first stamping block 21. The first hydraulic telescopic rod 20 is arranged on the support frame 10, and the extending shaft of the first hydraulic telescopic rod 20 is connected to the first stamping block 21.

[0068] It should be noted that the bottom of the first stamping block 21 described in this embodiment is arc-shaped and matches the arc shape at the end of the U-shaped stamping slot, thereby ensuring the U-shaped stamping effect of the steel plate.

[0069] In an embodiment of the present application, as Figure 3 shown, the circular stamping assembly 4 may include a third hydraulic telescopic rod 40, a first semi-circular mold 41, and a second semi-circular mold 42.

[0070] Among them, the third hydraulic telescopic rod 40 is arranged on one side of the workbench 1, the extending shaft of the third hydraulic telescopic rod 40 is connected to the first semi-circular mold 41, the first semi-circular mold 41 is arranged in the forming stamping slot 13, the second semi-circular mold 42 is arranged on the workbench 1 and is located in the forming stamping slot 13, and the first semi-circular mold 41 and the second semi-circular mold 42 are in pressing cooperation.

[0071] It should be noted that the surface roughness of the first semi-circular mold 41 and the second semi-circular mold 42 described in this embodiment is less than 0.4 microns, the surface roughness of the first stamping block 21 and the second stamping block 312 is less than 0.4 microns, and the surface roughness of the inner surface of the rectangular stamping groove 12 and the U-shaped stamping groove 11 (i.e., the surface corresponding to the workbench 1) is less than 0.4 microns, so as to ensure the quality of the stamping forming of the steel plate.

[0072] It should be noted that the first hydraulic telescopic rod 20, the second hydraulic telescopic rod 300 and the third hydraulic telescopic rod 40 described in this embodiment are common components on the market. They are respectively connected to a hydraulic system (not shown in the figure), and the hydraulic system is also a common component on the market, so no detailed description will be made here.

[0073] It should be noted that the diameter of the inner circle formed after the first semi-circular mold 41 and the second semi-circular mold 42 are closed in this embodiment is equal to the outer diameter of the formed circular steel plate, so as to avoid the situation of extrusion deformation at the interface position of the circular steel plate (i.e., the position where the ends of the two ends of the circular steel plate are in contact), thus ensuring the quality of the stamping forming of the steel plate.

[0074] In an embodiment of the present application, as Figure 1 and Figure 6 shown, a limiting block 18 is provided on the workbench 1, and limiting strips 3110 are respectively provided on the connecting block 311 and the second stamping block 312. The limiting strips 3110 are respectively slidably connected to the limiting grooves opened on the limiting block 18.

[0075] It can be understood that through the setting of the limiting block 18 and the limiting strips 3110, the connecting block 311 and the second stamping block 312 can be limited, so as to prevent the connecting block 311 from driving the second stamping block 312 to rotate and deflect when contacting the steel plate, resulting in the situation that the steel plate cannot be effectively stamped into the rectangular stamping groove 12.

[0076] In an embodiment of the present application, as Figure 1 and Figure 3 shown, a material taking hole 16 is opened on the workbench 1, and the material taking hole 16 is communicated with the forming stamping groove 13.

[0077] It can be understood that through the setting of the material taking hole 16, it is convenient to take the steel plate after forming.

[0078] In an embodiment of the present application, as Figure 1 shown, a positioning baffle 17 is provided on the workbench 1.

[0079] It can be understood that through the setting of the positioning baffle 17, it is convenient to determine the placement position of the steel plate.

[0080] Specifically, during the actual operation process, the relevant operators align a corner of the steel plate with the positioning baffle 17, start the device, and the controller (not shown in the figure) controls the two U-shaped stamping components 2 to do work and extend (i.e., the first hydraulic telescopic rod 20 extends, driving the first stamping block 21 to extend), and squeezes the steel plate into the U-shaped stamping groove 11, so that the steel plate is stamped into a U shape. During the extension process of the two U-shaped stamping components 2, the two middle stamping parts 30 of the diamond-shaped stamping component 3 extend synchronously, so that the second hydraulic telescopic rod 300 extends, driving the limit sleeve 301 to extend. The limit sleeve 301 drives the control rod 310 and the connecting block 311 to move, so that the second stamping block 312 is in a certain abutting state with the steel plate, thus achieving the effect of abutting and limiting the steel plate.

[0081] The controller controls the two U-shaped stamping components 2 to contract, so that the first hydraulic telescopic rod 20 contracts, driving the first stamping block 21 to contract. Then the controller controls the two middle stamping parts 30 in the diamond-shaped stamping component 3 to continue to extend, so that the second hydraulic telescopic rod 300 drives the limit sleeve 301 and the control rod 310 to continue to extend, and the second stamping block 312 continuously abuts against the middle of the steel plate (at this time, one end of the second stamping block 312 contracts into the connecting block 311). In this way, the middle part of the steel plate is gradually deformed and gradually moves into the rectangular stamping groove 12, so that the two ends of the U-shaped steel plate gradually bend in the opposite direction of the inner hopper, and follow the middle part of the U-shaped steel plate into the rectangular stamping groove 12, and stamp the U-shaped steel plate into a diamond shape, and the diamond-shaped steel plate surrounds and covers the second stamping block 312 and the connecting block 311.

[0082] The controller continues to control the two middle stamping parts 30 to extend, so that the variable-distance abutting mechanism 31 and one end of the diamond-shaped steel plate gradually enter the forming stamping groove 13 (at this time, the second stamping block 312 and the connecting block 311 are in the extended state and abut against the diamond-shaped steel plate), and the gear 313 moves to the rack 15, and the gear 313 meshes with the rack 15 and rotates. The rotation of the gear 313 drives the control rod 310 to rotate. The rotation of the control rod 310 drives the connecting block 311 and the second stamping block 312 to rotate, and drives the diamond-shaped steel plate abutting against the connecting block 311 and the second stamping block 312 to rotate, and drives the diamond-shaped steel plate to rotate to a suitable stamping position (that is, the position where the circular stamping component 4 can effectively stamp the diamond-shaped steel plate into a circle). The controller controls the third hydraulic telescopic rod 40 to extend, and drives the first semi-circular mold 41 to move towards the second semi-circular mold 42. During the process of moving and closing the mold, the diamond-shaped steel plate is squeezed and stamped into a circle, and the two ends of the circular steel plate are in an abutting state. The relevant operators take out the formed circular steel plate through the material taking hole 16, and the controller controls each component to return to the initial position, thus completing the primary forming of the steel plate.

[0083] In summary, the steel plate stamping and forming device according to the embodiments of the present application enables the steel plate to be formed in one step, and the two ends of the formed steel plate are in a tightened state, eliminating the need for subsequent separate tightening of both sides of the steel plate, thereby improving the stamping and forming efficiency of the steel plate and the subsequent processing efficiency of the steel plate.
