[0002] Stainless steel has the characteristics of being rust-proof and corrosion-resistant, and is widely used in various fields. In the field of electronic products, stainless steel can be used as components of electronic products. Before stainless steel is used to make electronic product components, it is generally necessary to use special equipment for surface treatment. The existing surface treatment processes include the following processes: removing surface defects, rolling, alkali washing, annealing and laser texturing.

[0003] The special equipment in the prior art has the following defects or problems when performing the above process:

[0004] (1) When the steel plate blank raw material is subjected to the process of removing surface defects, the steel plate blank needs to be clamped and positioned, so that the clamping position of the steel plate blank cannot be subjected to the process of removing surface defects. Then, in the subsequent processing, the aforementioned clamping position needs to be cut off, which results in the waste of the steel plate blank raw material.

[0005] (2) When performing the surface defect removal process, in order to coordinate the clamping and positioning of the steel plate blank raw material, it is generally necessary to set a raised support platform to lift the raw material to coordinate the clamping and positioning, and the size of the support platform is generally adapted to the size of the raw material.

DETAILED DESCRIPTION

[0051] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0052] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0053] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0054] One aspect of the present application provides a stainless steel surface treatment device, such as Figures 1 to 24 As shown, one preferred embodiment includes a frame 1 and a placing block lifting mechanism 3 and a placing block unloading mechanism 2 installed on the frame 1. A horizontal workbench 100 is arranged in the middle of the frame 1; the placing block lifting mechanism 3 and the placing block unloading mechanism 2 are both located on the side of the workbench 100 to avoid interference with the subsequent grinding of the steel plate blank 600 and to provide sufficient space for the placement of the steel plate blank 600.

[0055] Among them, a first placement block 110 is fixed on the workbench 100; the placement block lifting mechanism 3 includes a lifting mechanism 31 and a plurality of second placement blocks 32 neatly arranged and placed on the lifting mechanism 31. The second placement blocks 32 can cooperate with the first placement blocks 110 to form a placement table for placing the steel plate blank 600; and different numbers of second placement blocks 32 can cooperate with the first placement blocks 110 to form a placement table for placing steel plate blanks 600 of different sizes to be polished.

[0056] The placement block unloading mechanism 2 includes at least two working modes; among them, in the first mode, the placement block unloading mechanism 2 can push the second placement block 32 to disengage from the lifting mechanism 31 until it moves to cooperate with the first placement block 110 or the previous second placement block 32 to increase the width of the formed placement table; the second mode: the placement block unloading mechanism 2 can collect the second placement block 32 constituting the placement table into the lifting mechanism 31, thereby reducing the width of the placement table.

[0057] It is understandable that, when the steel plate blank 600 is being polished, it is generally necessary to clamp and limit the steel plate blank 600. In order to ensure the stability of the clamping of the steel plate blank 600, the displacement of the steel plate blank 600 in the vertical direction and the horizontal direction can be limited; and for the displacement in the horizontal direction, the side of the steel plate blank 600 needs to be squeezed and limited, which requires a certain height difference between the side of the steel plate blank 600 and the workbench 100, so that the steel plate blank 600 can be easily clamped. Due to the height difference between the steel plate blank 600 and the workbench 100, a placement table needs to be set to support the steel plate blank 600. Assuming that the pressing of the steel plate blank 600 is achieved on both sides in the width direction, if the width of the placement table is smaller than the width of the steel plate blank 600, the steel plate blank 600 will bend during pressing, which will lead to uneven surface treatment during subsequent surface treatment; if the width of the placement table is larger than the width of the steel plate blank 600, the steel plate blank 600 will not be able to be pressed.

[0058] Therefore, a first placement block 110 can be fixed on the workbench 100, and the width of the first placement block 110 is the minimum width of the steel plate blank 600 that can be surface treated in the present application. For steel plate blanks 600 with a width greater than the first placement block 110, different numbers of second placement blocks 32 can be connected to the first placement block 110, thereby forming a placement table that can meet the grinding of steel plate blanks 600 of different widths; and the width of the formed placement table is substantially equal to the width of the steel plate blank 600 to be ground.

[0059] In this embodiment, the number of the placement block lifting mechanism 3 can be one or two; in order to ensure the structural stability of the placement table, the number of the placement block lifting mechanism 3 is preferably two, for example Figure 1 As shown. The two placement block lifting mechanisms 3 are respectively located on both sides of the workbench 100 along the width direction, so the number of placement block unloading mechanisms 2 is also two, and they correspond to the two sides of the workbench 100 along the width direction. Therefore, when a new placement table is formed, the number of second placement blocks 32 can be increased or decreased simultaneously on both sides of the placement table along the width direction; or the number of second placement blocks 32 on both sides can be increased or decreased alternately. In order to facilitate the description of subsequent content, it is preferred to adjust the width of the placement table by increasing or decreasing the number of second placement blocks 32 on both sides of the first placement block 110 at the same time.

[0060] One of the embodiments of the present application is as follows: Figure 1 , Figure 2 , Figure 6 , Figure 7 and Fig.11As shown in the figure, the placing block blanking mechanism 2 includes a first displacement device 21 and a push plate; the first displacement device 21 is horizontally installed on the side of the workbench 100, and the push plate can be horizontally moved along the width direction of the workbench 100 under the drive of the first displacement device 21. The rack 1 is provided with a feeding area 120 below both sides of the workbench 100, and feeding ports 130 communicating with the feeding area 120 are provided on both sides of the workbench 100. The placing block lifting mechanism 3 is correspondingly installed in the feeding area 120; the lifting mechanism 31 includes a second displacement device 311 and a placing plate 312; a plurality of second placing blocks 32 are vertically arranged on the placing plate 312, and the second displacement device 311 can drive the placing plate 312 together with the placed second placing blocks 32 to move vertically along the feeding port 130.

[0061] When it is necessary to increase the width of the placing table, that is, when the above-mentioned first working mode is carried out; the lifting mechanism 31 can first vertically lift the required second placing blocks 32 along the feeding port 130 through the placing plate 312 until they are horizontally flush with the first placing table 110; then the first displacement device 21 can horizontally drive the push plate to push the second placing blocks 32 placed on the placing plate 312 to be snap-connected with the first placing block 110 or the previous second placing block 32, so as to form a placing table with a new width.

[0062] When it is necessary to reduce the width of the placing table, that is, when the above-mentioned second working mode is carried out; the lifting mechanism 31 can first drive the placing plate 312 to move vertically until the idle position on the placing plate 312 is flush with the placing table; then the push plate is horizontally moved under the drive of the second displacement device 311 to contact and squeeze the outermost second placing block 32 of the placing table, so that the outermost second placing block 32 forming the placing table is disengaged from the snap connection, and then they move together with the push plate to the idle position on the placing plate 312 for placement.

[0063] In this embodiment, as Figures 6 to 8 shown, placing holes 3211 are provided at both ends of the second placing block 32, and a plurality of placing rods are arranged at intervals along the vertical direction on both sides of the placing plate 312; thus, the second placing block 32 can be inserted and placed through the placing holes 3211 at both ends and the correspondingly arranged placing rods. At least one pair of jacks 3212 are provided in the middle of the second placing block 32; at least one pair of inserting rods 232 that can be inserted and matched with the jacks 3212 are provided on the push plate. The placing plate 312 is in a "U" shape or a "凵" shape, so that the placing rods can be arranged on the vertical sides on both sides of the placing plate 312; at the same time, the push plate can be inserted with the second placing block 32 along the vacant area in the middle of the placing plate 312. An avoidance hole 111 that can be aligned with the jack 3212 is provided on the side of the first placing block 110, so that when the first placing block 110 is connected to the first second placing block 32, the inserting rod 232 can extend into the avoidance hole 111 to avoid interference with the first placing block 110.

[0064] In this embodiment, in order to further improve the plug-in stability between the second placement block 32 and the push plate and the placement plate 312, a magnetic setting can be performed between the second placement block 32 and the push plate, and a magnetic setting can be performed between the second placement block 32 and the placement plate 312 at the same time; thereby ensuring that the second placement block 32 is stably placed on the placement plate 312, or can be stably detached from the placement table together with the push plate.

[0065] It should be known that the specific values ​​of the steel plate blanks 600 of different widths are all standard, that is, the width difference between the steel plate blanks 600 of adjacent sizes is generally a fixed value X, and the width difference between the steel plate blank 600 of the maximum width and the steel plate blank 600 of the minimum width is nX. When setting the width of the second placement block 32, there are generally two design schemes.

[0066] Solution 1: The widths of the second placement blocks 32 are all equal, and the width of the second placement blocks 32 is Y, and the number of the second placement blocks 32 is N; then it is only necessary to satisfy 2NY=nX. For example, Y=0.5X, then N=n.

[0067] Solution 2: The widths of the second placement blocks 32 are not equal; the widths of the second placement blocks 32 placed on the placement plate 312 may be increased from top to bottom. Then, it is only necessary to ensure that the total width of all the second placement blocks 32 is nk.

[0068] It is understandable that when the width of the placement table is required to be larger, the number of second placement blocks 32 required for the above-mentioned solution 1 may be larger, and the number of second placement blocks 32 required for the above-mentioned solution 2 may be smaller; when the width of the discharge port 130 required by the wider second placement block 32 is larger, it may lead to insufficient working area of ​​the workbench 100. In this application, the above-mentioned solution 1 is preferably adopted.

[0069] In this embodiment, Figure 6 and Fig.11 As shown, there are two push plates of the placement block unloading mechanism, namely, the first push plate 22 and the second push plate 23; the first push plate 22 is connected to the output end of the first displacement device 21, and the second push plate 23 is slidably connected to the first push plate 22 through a guide rod, and a first spring 24 is sleeved on the guide rod, and the two ends of the first spring 24 are respectively connected to the first push plate 22 and the second push plate 23, so that the first push plate 22 and the second push plate 23 are elastically slidably connected. The insertion rod 232 is provided on the second push plate 23, so that when the first displacement device 21 drives the second push plate 23 to squeeze the second placement block 32, the elastic sliding between the second push plate 23 and the first push plate 22 can be used to avoid the second placement block 32 from being deformed due to rigid squeezing with the second placement block 32.

[0070] In this embodiment, Figure 4 and Figure 8 As shown, the side of the first placement block 110 is provided with a clamping hole 112; the second placement block 32 includes a body 321, a transmission assembly 322 and a clamping shaft 323; the side of the body 321 is also provided with a clamping hole 112; the clamping shaft 323 is rotatably mounted on the body 321; the transmission assembly 322 is mounted inside the body 321, and the output end of the transmission assembly 322 is matched with the end of the clamping shaft 323 located inside the body 321. When the first working mode is performed, the second push plate 23 can first push the second placement block 32 until its own clamping shaft 323 extends into the clamping hole 112 of the first placement block 110 or the previous second placement block 32; then, the second push plate 23 can continue to move to squeeze the input end of the transmission assembly 322, so as to drive the transmission assembly 322 to drive the clamping shaft 323 to rotate to a set angle, so that the clamping shaft 323 can be engaged with the clamping hole 112. When the second working mode is implemented, the second push plate 23 can be moved again to the outermost second placement block 32 of the placement table, and squeeze the input end of the internal transmission component 322 to drive the transmission component 322 to drive the engagement shaft 323 to rotate the set angle again, thereby disengaging the engagement shaft 323 from the engagement hole 112; then, the disengaged second placement block 32 can be reset to the corresponding position on the placement plate 312 along with the second push plate 23 under the magnetic adsorption force.

[0071] Specifically, Figure 5 , Fig.10 and Fig.12 As shown in FIG. 1 , the rear portion of the clamping hole 112 is a clamping area 114 with a diameter larger than that of the front portion, and the front side wall of the clamping hole 112 is provided with a slot 113 connected to the clamping area 114. The rear end of the clamping shaft 323 extends to the inside of the body 321 to cooperate with the transmission assembly 322; the front end of the clamping shaft 323 extends to the outside of the body 321, and the front side wall is provided with a clamping block 3231 protruding radially. When the clamping shaft 323 extends into the clamping hole 112, as shown in FIG. Fig.12 As shown in (1), the card block 3231 can extend along the slot 113 to the engagement area 114; when the first working mode is performed, as shown in FIG. Fig.12 As shown in (2), the block 3231 can rotate 180° along the engagement shaft 323, so that the block 3231 passes over the slot 113 along the circumferential direction to engage with the engagement hole 112; when the second working mode is performed, as shown in FIG. Fig.12 As shown in (1), the clamping block 3231 can rotate 180° again with the engaging shaft 323 so that the clamping block 3231 faces the slot 113 again, and then the second placement block 32 can be moved to the placement plate 312 together with the second push plate 23 under the magnetic attraction.

[0072] It is understandable that the set angle can be other angles besides 180°, such as 90°. When the set angle is 90°, two slots 113 can be symmetrically arranged on the front side wall of the clamping hole 112; thus, when the first working mode is performed, the clamping block 3231 can be rotated 90° from the position of one of the slots 113, and then when the second working mode is performed, the clamping block 3231 can be rotated 90° again to face the other slot 113, so that it can be separated from the clamping hole 112 under the magnetic attraction of the second push plate 23.

[0073] At the same time, in order to improve the structural stability of the formed placement table, the number of the clamping holes 112 provided on the side of the second placement block 32 and the first placement block 110 can be multiple, for example Figure 4 and Figure 8 As shown, the number of the engaging holes 112 is two and they are symmetrically arranged; the number of the engaging shafts 323 and the transmission components 322 is also two correspondingly.

[0074] It can also be understood that, in order to facilitate installation, the locking shaft 323 and the locking hole 112 on the second placement block 32 are spaced apart in the length direction, so that between two adjacent second placement blocks 32, the position of the locking shaft 323 of the rear second placement block 32 corresponds to the locking hole 112 of the front second placement block 32.

[0075] In this embodiment, Figure 6 and Figures 8 to 10As shown, the second push plate 23 is provided with a wedge-shaped first pressing block 231 corresponding to the number of the transmission assembly 322, and the length of the first pressing block 231 is less than the length of the insertion rod 232. The transmission assembly 322 includes a gear set 3225 and a second pressing block 3221; the gear set 3225 is installed in the body 321 through a one-way bearing 700; the second pressing block 3221 is wedge-shaped and elastically connected to the body 321, and a second tooth plate 3222 is connected to one side of the second pressing block 3221, and the second tooth plate 3222 can mesh with the input end of the gear set 3225, and the output end of the gear set 3225 can mesh with the tooth shaft section 3232 provided at the rear end of the engaging shaft 323. The side of the body 321 is provided with a corresponding number of opening grooves 3213 that penetrate through, and the opening grooves 3213 are directly opposite to the second pressing block 3221. When the placing block unloading mechanism 2 is working, the second push plate 23 is driven by the first displacement device 21 to extend into the opening groove 3213 through the first pressing block 231 and elastically squeeze the second pressing block 3221, so that the second pressing block 3221 can drive the second tooth plate 3222 to mesh with the gear set 3225, and the gear set 3225 can convert the movement of the second tooth plate 3222 into rotation and amplify the stroke to drive the engagement shaft 323 to rotate. When the first pressing block 231 is separated from the second pressing block 3221, the second pressing block 3221 can be elastically reset, and at this time, the gear set 3225 keeps the engagement shaft 323 in a stationary state through the one-way bearing 700.

[0076] Specifically, in order to improve the movement stability of the second tooth plate 3222, as Fig. 9 As shown, the second pressing block 3221 is slidably connected with the body 321 through a fixed guide rod 3224, and the guide rod 3224 is also sleeved with a second spring 3223, and the two ends of the second spring 3223 are respectively connected to the body 321 and the guide rod 3224, so that the elastic sliding connection between the second pressing block 3221 and the body 321 can be achieved. When the second pressing block 3221 is squeezed by the first pressing block 231 to move, the second spring 3223 can be deformed, and at this time the one-way bearing 700 is in a bite state, thereby driving the engaging shaft 323 to rotate. When the first pressing block 231 gradually disengages from the squeezing of the second pressing block 3221, the second pressing block 3221 can be reset under the elastic force of the second spring 3223, and at this time the one-way bearing 700 is in a free state, and then the output end of the gear set 3225 remains stationary, that is, the engaging shaft 323 also remains in a stationary state of engagement.

[0077] Considering the transmission friction between the transmission components 322, when the second pressing block 3221 is reset, the engaging shaft 323 may deflect slightly, which may cause the engaging shaft 323 to be unable to disengage from the engaging hole 112. Therefore, in order to further ensure the rotation stability of the engaging shaft 323; Fig.10 and Fig.13As shown, a pair of first limiting grooves 3233 are symmetrically arranged on the rear end side of the engaging shaft 323; a mounting block 3214 is arranged on the side of the engaging shaft 323 inside the body 321, and a first mounting groove 3215 extending radially along the engaging shaft 323 is arranged on the mounting block 3214. A first limiting block 3241 is slidably installed in the first mounting groove 3215 through a third spring 3242, and the first limiting block 3241 can be limitedly matched with the first limiting groove 3233 under the elastic force of the third spring 3242; that is, when the engaging shaft 323 is engaged or disengaged, the first limiting block 3241 is limitedly matched with the two first limiting grooves 3233 under the elastic force.

[0078] One of the embodiments of the present application is as follows: Figure 1 and Figures 14 to 21 As shown, the stainless steel surface treatment equipment also includes a grinding mechanism 4 and a pressing mechanism 5 installed above the workbench 100. The workbench 100 includes a first area 101 and a second area 102 along the length direction; when the grinding mechanism 4 grinds the steel plate blank 600 placed on the placement table in the first area 101, the pressing mechanism 5 presses and limits the steel plate blank 600 in the second area 102, thereby ensuring that the grinding mechanism 4 completely grinds the portion of the steel plate blank 600 located in the first area 101; when the grinding mechanism 4 grinds the steel plate blank 600 placed on the placement table in the second area 102, the pressing mechanism 5 presses and limits the steel plate blank 600 in the first area 101, thereby ensuring that the grinding mechanism 4 completely grinds the portion of the steel plate blank 600 located in the second area 101.

[0079] It can be understood that according to the grinding position of the grinding mechanism 4, the pressing mechanism 5 can press and limit the steel plate blank 600 in the opposite position, thereby avoiding interference between the grinding mechanism 4 and the pressing mechanism 5, and then ensuring that all positions of the steel plate blank 600 can be ground to improve the grinding quality of the steel plate blank 600.

[0080] In this embodiment, Fig.14 As shown, the frame 1 is fixed with support plates 140 extending upward on both sides of the workbench 100; the grinding mechanism 4 is installed on the support plate 140. The grinding mechanism 4 includes a grinder 41, a third displacement device 42 and a fourth displacement device 43; wherein the grinder 41 is installed on the third displacement device 42, so that the third displacement device 42 can drive the grinder 41 to grind the steel plate blank 600 along the width direction of the workbench 100; the third displacement device 42 is installed on the fourth displacement device 43, so that the fourth displacement device 43 can drive the third displacement device 42 and the grinder 41 to grind the steel plate blank 600 along the length direction of the workbench 100.

[0081] It is understandable that the specific structure and working principle of the grinder 41 are well known to those skilled in the art.

[0082] In this embodiment, Figure 2 and Figures 15 to 21 As shown, the pressing mechanism 5 is installed on the support plate 140 and is located above the grinding mechanism 4; the pressing mechanism 5 includes at least one traction assembly 51 and a pair of pressing assemblies 52. The two pressing assemblies 52 correspond to the first area 101 and the second area 102 respectively, and are both connected to the support plate 140 and connected through the driving structure; the traction assembly 51 can simultaneously drive the two pressing assemblies 52 to move vertically, and then drive the two pressing assemblies 52 to rotate through the driving structure. There is a phase difference between the two pressing assemblies 52, so that the two pressing assemblies 52 can perform the first process and the second process under the drive of the traction assembly 51; wherein, in the first process: the two pressing assemblies 52 are spaced apart from the placing table under the drive of the traction assembly 51; in the second process: one of the pressing assemblies 52 is pressed against the steel plate blank 600 on the placing table under the drive of the traction assembly 51, and the other pressing assembly 52 is spaced apart from the placing table.

[0083] It is understandable that in the first process, if Fig.19 As shown, the two pressing assemblies 52 are spaced apart from the placement table, so that the steel plate blank 600 can be placed on the placement table by a robot or a conveying device or manually; then the placed steel plate blank 600 can be corrected by the second push plate 23 of the placement block unloading mechanism 2. Then, when the second process is performed, as shown in FIG. Fig. 20 As shown, the pressing assembly 52 far away from the grinder 41 can press the steel plate blank 600 under the drive of the traction assembly 51, and at this time, the other pressing assembly 52 rotates accordingly, but still keeps a distance from the placement table; when the grinder 41 moves close to the pressing assembly 52 in the pressing state, as shown in FIG. Fig.21 As shown, the traction assembly 51 can be driven again, so that the pressing assembly 52 in the clamping state rotates to disengage it from the placement table, and the other pressing assembly 52 rotates to clamp the steel plate blank 600 on the placement table. It should be known that when the two pressing assemblies 52 exchange the clamping state, the grinding mechanism 4 is in a parking state.

[0084] In this embodiment, Fig.16 , Fig.23 and Fig.24As shown, the pressing assembly 52 includes a mounting frame 521, a clamping assembly 524 and a mounting plate 525; the mounting frame 521 is installed on the support plate 140 and cooperates through the driving structure; the pressing assembly 52 clamps the steel plate blank 600 on the placement table through the clamping assembly 524. The clamping assembly 524 includes a plurality of clamping blocks 5240 hinged to each other, and the clamping assembly 524 is hinged to the two ends of the mounting plate 525 at both ends; the length of the clamping assembly 524 is greater than the horizontal extension length of the mounting plate 525, so that when the clamping assembly 524 is clamped with the steel plate blank 600 on the placement table, the clamping assembly 524 can form a first clamping section 5241 pressed on the upper end surface of the steel plate blank 600, and a second clamping section 5242 deflected on both sides of the first clamping section 5241; wherein, the first clamping section 5241 can limit the displacement of the steel plate blank 600 in the vertical direction, and the deflection position of the first clamping section 5241 and the second clamping section 5242 is corresponding to the side end of the steel plate blank 600, thereby limiting the horizontal displacement of the steel plate blank 600.

[0085] It is understandable that, since the pressing block 5240 is made of a rigid material, the pressing block 5240 corresponding to the deflected position of the first pressing section 5241 and the second pressing section 5242 can be rigidly pressed against the side of the steel plate blank 600 to ensure that the steel plate blank 600 does not deviate horizontally. At the same time, by setting the extension length of the pressing assembly 524 to be greater than the horizontal extension length of the mounting plate 525, it can be ensured that the deflected second pressing section 5242 can be formed when the pressing assembly 524 is pressed against the steel plate blank 600. Moreover, according to the different widths of the pressed steel plate blank 600, the deflection angles of the formed second pressing section 5242 and the first pressing section 5241 are different.

[0086] At the same time, the lowering height of the mounting plate 525 corresponding to the different deflection angles of the second pressing section 5242 and the first pressing section 5241 is different. In order to ensure that the pressing assembly 524 can be smoothly pressed with steel plate blanks 600 of different widths, the mounting plate 525 can be elastically connected to the mounting frame 521; for example Fig.16 As shown, the mounting plate 525 is slidably connected to the mounting frame 521 through a plurality of connecting rods 5251, and fourth springs 526 are sleeved on the connecting rods 5251, so that the connecting rods 5251 and the mounting frame 521 are elastically slidably connected through the fourth springs 526, and then different descending heights of the mounting plate 525 are achieved through different deformation amounts of the fourth springs 526. Of course, different descending heights of the mounting plate 525 can also be achieved through different traction heights of the traction assembly 51.

[0087] In this embodiment, Figure 3 and Fig.16As shown, the support plate 140 is provided with a guide groove 141; the pressing assembly 52 also includes a pair of guide blocks 522, and the guide blocks 522 are slidably matched with the guide groove 141. Support shafts 5210 are provided on both sides of the mounting frame 521, and the support shafts 5210 and the guide blocks 522 are matched through a limiting structure. The driving structure includes a driving gear 523 and a first tooth plate 142; the first tooth plate 142 is fixedly arranged on the support plate 140 and close to the upper part of the guide groove 141; the driving gear 523 is installed on the support shaft 5210 through a one-way bearing 700. When the traction assembly 51 drives the pressing assembly 52 to move vertically through the support shaft 5210, the one-way meshing of the driving gear 523 and the first tooth plate 142 can drive the support shaft 5210 to rotate 120° around the axis, and after the rotation is completed, the support shaft 5210 is locked and limited by the limiting structure; and there is a phase difference of 120° between the two pressing assemblies 52.

[0088] It is understandable that the pressing component 52 needs to have three position states during one rotation, and the change angle between two adjacent states is 120°; therefore, the phase difference between the two pressing components 52 is also 120°.

[0089] At the same time, in order to facilitate the smooth separation of the pressing assembly 52 in the pressed state from the steel plate blank 600 through rotation, it is necessary to first lift the pressing assembly 52 to a certain height, and then rotate the pressing assembly 52 120 degrees to avoid interference between the pressing assembly 52 and the steel plate blank 600 during the rotation process. Therefore, the first tooth plate 142 can be arranged at the upper part of the guide groove 141, so that when the support shaft 5210 drives the guide block 522 to move vertically upward from the lower part of the guide groove 141 to the process close to the first tooth plate 142, Fig.17 As shown, the mounting frame 521 can drive the clamping assembly 524 to vertically separate from the steel plate blank 600 to a position that satisfies the rotation requirements. Fig.18 As shown, the mounting frame 521 can be rotated 120° by the one-way meshing of the driving gear 523 and the first tooth plate 142. The mounting frame 521 can be rotated by the upward movement of the driving gear 523 and the meshing of the first tooth plate 142, or by the downward movement of the driving gear 523 and the meshing of the first tooth plate 142.

[0090] It can also be understood that when the pressing component 52 is in a non-pressed state, due to the gravity of the pressing component 52, the pressing component 52 has a tendency to deflect downward. In order to ensure that the pressing component 52 can remain stable in the non-pressed state, a limiting structure needs to be set to limit the movement state of the pressing component 52 at a specific position.

[0091] In this embodiment, Fig. 22As shown, a mounting hole is provided inside the guide block 522, and the support shaft 5210 can extend into the mounting hole and be rotatably connected. The guide block 522 is provided with at least one second mounting groove 5220 along the radial direction on the side wall of the mounting hole. The limiting structure includes three second limiting grooves 5211 arranged on the side wall of the support shaft 5210 and distributed at equal intervals along the circumferential direction, and a second limiting block 5271 and a fifth spring 5272 installed in the second mounting groove 5220; the second limiting block 5271 can be limitedly matched with the second limiting groove 5211 at the corresponding position under the elastic force of the fifth spring 5272, thereby limiting the rotation of the pressing assembly 52 at the set position.

[0092] It is understandable that the three second limiting grooves 5211 on the support shaft 5210 correspond to the three position states of the pressing assembly 52. ​​In addition, in order to improve the movement restriction capability of the pressing assembly 52 at the set position, a plurality of second mounting grooves 5220 may be provided, for example Fig. 22 As shown, the number of the second mounting grooves 5220 is three, and the three second mounting grooves 5220 are arranged at equal intervals along the circumferential direction. Second limiting blocks 5271 are installed in the three second mounting grooves 5220 through fifth springs 5272.

[0093] In this embodiment, Fig.15 , Fig.17 and Fig.18 As shown, in order to ensure the movement stability of the pressing assembly 52, the number of the traction assemblies 51 can be two, and the two traction assemblies 51 are respectively installed on the two support plates 140 and respectively connected to the two ends of the pressing assembly 52. ​​The traction assembly 51 includes a fifth displacement device 511 and a pair of traction plates 512; the output end of the fifth displacement device 511 is respectively hinged to the support shafts 5210 on the two mounting frames 521 through the two traction plates 512; and then, driven by the fifth displacement device 511, the two traction plates 512 can drive the two pressing assemblies 52 to slide vertically along the guide groove 141 synchronously.

[0094] In the present application, the specific structure and working principle of the displacement device are well known to those skilled in the art. Common displacement devices include telescopic cylinders, telescopic hydraulic cylinders, and linear motors.
