Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural tool production, and particularly relates to a limiting component, a calibration component, a calibration method, a steel stamper and a production method. Background Art

[0002] For brand recognition and differentiation, the LOGO is the core symbol for consumers to quickly recognize a brand. Differences are established through the LOGO among similar products, so consumers can quickly classify product attributes through the LOGO.

[0003] Currently, when the traditional steel stamper stamps a logo on a spade plate, the limiting is inaccurate, which affects the quality of the stamped LOGO. Moreover, when stamping logos on different spade plates, it is difficult to adjust the limiting component, which is time-consuming and laborious.

[0004] Moreover, when the existing spade plates are produced, after heating, stamping logos, profiling and curling the pants are carried out, that is, the heated spade plates go through three processes and then heat treatment. The three processes and the intermediate transfer process consume a lot of time, making the temperature of the spade plates lower during heat treatment, which affects the heat treatment quality of the spade plates. At the same time, when stamping a logo on the heated spade plate, the scale on the spade plate will wear the logo mold, making the font of the stamped logo gradually unclear.

[0005] Therefore, there is an urgent need to design a limiting component, a calibration component, a calibration method, a steel stamper and a production method to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a limiting component, which has the advantage of quickly limiting a spade plate.

[0007] Another purpose of the present invention is to provide a limiting component, which has the advantage of accurately limiting a spade plate, and solves the problem in the background art that inaccurate limiting affects the quality of the stamped LOGO.

[0008] Another purpose of the present invention is to provide a production method, which has the advantage of cold stamping a spade plate to ensure the temperature of the spade plate during heat treatment, and solves the problem in the background art that the quality of the spade plate is poor after heat treatment.

[0009] To achieve the above purpose, the specific technical solution of a steel stamper of the present invention is as follows: A limiting component is used to limit a spade plate. The spade plate includes a spade head and a spade neck. The spade head includes a side portion and a spade shoulder near one end of the spade neck. The limiting component is characterized in that it includes a first limiting block and a second limiting block for abutting against the same side of the spade plate. The first limiting block is provided with a first limiting surface and a second limiting surface. The first limiting surface and the second limiting surface respectively abut against the spade shoulder and the spade neck simultaneously. The second limiting block abuts against the side portion of the spade head. The abutting positions of the first limiting surface, the second limiting surface and the second limiting block with the spade shoulder, the spade neck and the side portion are all located on the same side of the spade plate.

[0010] Furthermore, it further includes a fixing member. The fixing member is arranged on the side of the spade plate away from the first limiting block and the second limiting block. The fixing member can move close to the spade plate to push the spade plate, so that the spade shoulder, the spade neck and the side portion respectively abut against the first limiting surface, the second limiting surface and the second limiting block at the abutting positions; the fixing member can also move away from the spade plate, thereby releasing the abutment.

[0011] Furthermore, the first limiting block and the second limiting block are movable to adjust the positions of the first limiting block and the second limiting block; the limiting component further includes a first supporting block and a second supporting block. The first limiting block can slide relative to the first supporting block along the sliding groove of the first supporting block to control the position of the first limiting block in the third direction or the fourth direction. The second limiting block can slide relative to the second supporting block along the sliding groove of the second supporting block to control the position of the second limiting block in the third direction or the fourth direction.

[0012] Furthermore, the limiting component further includes a supporting rod. The supporting rod is perpendicularly arranged with the first limiting block and the second limiting block. The first supporting block and the second supporting block can slide along the supporting rod to control the positions of the first limiting block and the second limiting block in the first direction or the second direction.

[0013] Furthermore, locking members are arranged on both the first supporting block and the second supporting block. By turning the locking members, the first limiting block and the second limiting block can be fastened or loosened.

[0014] The fixing member includes a first fixing plate and a second fixing plate. The first fixing plate and the second fixing plate are fixedly connected. When the fixing member fixes the spade plate, the first fixing plate abuts against the connection position of the spade head and the spade shoulder, and the second fixing plate abuts against the connection position of the two side portions.

[0015] A calibration component includes a calibration plate. The calibration plate is provided with a first calibration block and a second calibration block. When the calibration component and the spade plate are stacked and placed, the first calibration block coincides with the connection position of the spade shoulder and the spade neck, and the second calibration block coincides with the side portion of the spade head. The first calibration block is provided with a first calibration surface and a second calibration surface. The first calibration surface has the same shape as the spade shoulder, and the second limiting surface has the same shape as the spade neck.

[0016] A calibration method uses the above calibration component to calibrate the above limiting component, and further includes the following steps: Fix the calibration component; Move the first limit block until the first limit surface of the first limit block abuts against the first calibration surface of the first calibration block, and the second limit surface of the first limit block abuts against the second calibration surface of the first calibration block; Move the second limit block until the second limit block abuts against the second calibration block; Fasten the first limit block and the second limit block.

[0017] Furthermore, when moving the first limit block until the first limit surface of the first limit block abuts against the first calibration surface of the first calibration block, and the second limit surface of the first limit block abuts against the second calibration surface of the first calibration block, the following steps are included: Move the first limit block along the third direction or the fourth direction until the first limit surface of the first limit block abuts against the first calibration surface of the first calibration block; Move the first limit block along the first direction or the second direction until the second limit surface of the first limit block abuts against the second calibration surface of the first calibration block.

[0018] An embossing device includes the above-mentioned limit component, and further includes an upper die component and a lower die component. The lower die component is for placing the shovel plate, and the upper die component can slide relative to the lower die component to emboss the shovel plate with a mark. The limit component is arranged on the lower die component, and the first limit block and the second limit block and the fixing part are respectively located on both sides of the lower die component.

[0019] A production method is characterized in that it includes the embossing device as described in claim 9 above, and further includes the following steps: Cut the raw material and cut it into sheet materials according to the size of the shovel plate; Use the embossing device to emboss the shovel plate with a mark; Put the embossed shovel plate into a heating furnace for high-temperature softening; Flip the high-temperature softened shovel plate; Stamp and shape the flipped shovel plate, and at the same time roll the trousers; Perform heat treatment on the shaped and rolled-trouser shovel plate.

[0020] The present invention has the following advantages: The fixing effect on the shovel plate is improved through the limit component, and the limit component is adjustable to flexibly adapt to different types and sizes of shovel plates, and a customized exclusive calibration component is provided for different types and sizes, simplifying the adjustment process of the limit block and reducing the production change time. Through the fixing part, not only can the shovel plate be clamped, but also the shovel plate can be actively pushed to fit with the limit component, eliminating the placement error. By advancing the embossing mark process, the temperature of the shovel plate during heat treatment is ensured, and thus the quality of the shovel plate after heat treatment is ensured.

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present invention.

[0023] Those skilled in the art can understand that although some of the embodiments herein include some features included in other embodiments but not other features, the combination of the features of different embodiments means that it is within the scope of the present invention and forms different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0024] The following refers to the attached Figure 1 to the attached Figure 10 to describe a steel seal of the present invention.

[0025] The spade plate 7 includes a spade head 71 and a spade neck 72. A spade shoulder 711 is provided between the spade head 71 and the spade neck 72, and the spade head 71 is provided with a side portion 711.

[0026] The steel seal includes a machine tool 6. A lower die assembly 3 is fixedly connected to the workbench of the machine tool 6. The lower die assembly 3 is for placing the spade plate 7. An upper die assembly 4 is fixedly connected to the punch head of the machine tool 6. The punch head can reciprocate up and down, so as to drive the upper die to press down through the punch head, apply pressure, and stamp an identification on the spade plate 7 to complete the stamping action.

[0027] A limiting assembly 1 is provided on the lower die assembly 3. The limiting assembly 1 includes a first limiting block 11 and a second limiting block 12. The first limiting block 11 and the second limiting block 12 are located on the same side. The first limiting block 11 is provided with a first limiting surface 111 and a second limiting surface 112. The first limiting surface 111 and the second limiting surface 112 respectively abut against the spade shoulder 711 and the spade neck 72 at the same time. The second limiting block 12 abuts against the side portion 712 of the spade head 71. Among them, the abutting positions of the first limiting surface 111, the second limiting surface 712 and the second limiting block 12 with the spade shoulder 711, the spade neck 72 and the side portion 712 are all located on the same side of the spade plate 7. Thus, the spade plate 7 is limited by the first limiting block 11 and the second limiting block 12, and through the first limiting block 11, the spade plate 7 cannot slide in the first direction A and the third direction C.

[0028] A fixing member 5 is provided on the lower die assembly 3. The fixing member 5 is provided on the side of the spade plate 7 away from the first limiting block 11 and the second limiting block 12. The fixing member 5 can slide relative to the lower die assembly 3 to fix or unlock the spade plate 7. When the spade plate 7 is fixed, the fixing member 5 pushes the spade plate 7 to abut against the limiting assembly 1. Specifically, the fixing member 5 includes a first fixing plate 51 and a second fixing plate 52. The first fixing plate 51 and the second fixing plate 52 are fixedly connected. When the fixing member 5 fixes the spade plate 7, the first fixing plate 51 abuts against the connection position of the spade head 71 and the spade shoulder 711, and the second fixing plate 52 abuts against the connection positions of the two side portions 712.

[0029] When the manipulator places the spade plate 7 on the lower die assembly 3, by starting the fixing member 5, the first fixing plate 51 abuts against the connection position of the spade head 71 and the spade shoulder 711, the second fixing plate 52 abuts against the connection positions of the two side portions 712, and the first limiting surface 111 of the first limiting block 11 abuts against the spade shoulder 711, the second limiting surface 112 of the first limiting block 11 abuts against the spade neck 72, and the second limiting block 12 abuts against the side portion 712 of the spade head 71. Thus, the four directions of the spade plate 7 are all limited, ensuring that the spade plate 7 will not shake during stamping.

[0030] Moreover, the sliding trajectories of the first fixing plate 51 and the second fixing plate 52 are to slide along the fifth direction E. Thus, when the first fixing plate 51 and the second fixing plate 52 fix the spade plate 7, if the spade plate 7 is not in contact with the limiting component 1 at this time, the first fixing plate 51 and the second fixing plate 52 push the spade plate 7 along the fifth direction E until the first limiting surface 111 of the first limiting block 11 abuts against the spade shoulder 711, the second limiting surface 112 of the first limiting block 11 abuts against the spade neck 72, and the second limiting block 12 abuts against the spade head 71. Therefore, through the fixing member 5, while fixing the spade plate 7, the spade plate 7 can also be pushed to make the spade plate 7 abut against the limiting component 1, eliminating the placement error of the manipulator.

[0031] The fifth direction E is inclined, and the angle between the fifth direction E and the vertical line is 30° - 70°, which can be adjusted according to the actual situation.

[0032] The first fixing plate 51 and the second fixing plate 52 are connected to the output end of the cylinder 53. Through the cylinder 53, the first fixing plate 51 and the second fixing plate 52 can reciprocally slide along the fifth direction E, and the setting direction of the cylinder 53 can be adjusted to adjust the sliding direction of the first fixing plate 51 and the second fixing plate 52, that is, to adjust the fifth direction E.

[0033] The first limiting block 11 and the second limiting block 12 can slide to adjust the positions of the first limiting block 11 and the second limiting block 12 to be applicable to spade plates 7 of different types and sizes.

[0034] Specifically, the limiting component 1 further includes a first support block 13 and a second support block 14. The first support block 13 and the second support block 14 are provided with chutes. The first limiting block 11 can slide relative to the first support block 13 along the chute of the first support block 13 to control the position of the first limiting block 11 in the third direction C or the fourth direction D. The second limiting block 12 can slide relative to the second support block 14 along the chute of the second support block 14 to control the position of the second limiting block 12 in the third direction C or the fourth direction D, so that the positions of the first limiting block 11 and the second limiting block 12 in the third direction C or the fourth direction D can be respectively adjusted.

[0035] Specifically, the limiting component 1 further includes a support rod 15. The support rod 15 is perpendicularly arranged with the first limiting block 11 and the second limiting block 12. The first support block 13 and the second support block 14 can slide along the support rod 15 to control the positions of the first limiting block 11 and the second limiting block 12 in the first direction A or the second direction B, so that the positions of the first limiting block 11 and the second limiting block 12 in the first direction A or the second direction B can be respectively adjusted.

[0036] The position in the first direction A, the second direction B, the third direction C, and the fourth direction D can be adjusted through the first limiting block 11 and the second limiting block 12, so as to ensure that the limiting component 1 can adapt to different types and sizes of shovel plates 7.

[0037] Locking members 16 are provided on both the first support block 13 and the second support block 14. By turning the locking members 16, the first limiting block 11 and the second limiting block 12 can be fastened or loosened. After the position adjustment of the first limiting block 11 or the second limiting block 12 is completed, the locking members 16 thereon are tightened respectively, so as to fasten the first limiting block 11 and the second limiting block 12. When the position of the first limiting block 11 or the second limiting block 12 needs to be adjusted, the locking members 16 thereon are loosened, so that the positions of the first limiting block 11 and the second limiting block 12 can be adjusted.

[0038] The locking member 16 includes a first bolt. First screw holes are provided on both the first support block 13 and the second support block 14. The first screw hole on the first support block 13 communicates with the chute on the first support block 13, and the first screw hole on the second support block 14 communicates with the chute on the second support block 14. By turning the first bolt until the first bolt abuts against the first limiting block 11 or the second limiting block 12, the first limiting block 11 or the second limiting block 12 is locked and limited, and the third direction C and the fourth direction D of the first limiting block 11 and the second limiting block 12 are fixed.

[0039] The locking member 16 includes a second bolt. Second screw holes are provided on both the first support block 13 and the second support block 14. By turning the first bolt until the second bolt abuts against the support rod 15, the first limiting block 11 or the second limiting block 12 is locked and limited, and the first direction A and the second direction B of the first limiting block 11 and the second limiting block 12 are fixed.

[0040] It further includes a calibration component 2. The calibration component 2 includes a calibration plate 21. The calibration plate 21 is provided with a first calibration block 22 and a second calibration block 23. When the calibration component 2 and the shovel plate 7 are stacked, the first calibration block 22 coincides with the connection of the shovel shoulder 711 and the shovel neck 72, and the second calibration block 23 coincides with the shovel head 71. The first calibration block 22 is provided with a first calibration surface 221 and a second calibration surface 222. The first calibration surface 221 has the same shape as the shovel shoulder 711, and the second limiting surface 222 has the same shape as the shovel neck 72.

[0041] Different calibration components 2 can be set according to different types and sizes of shovel plates 7.

[0042] A calibration method, using the above calibration component 2 to position the above limiting component 1, further includes the following steps: Fix the calibration component 2; specifically, there are two fixing holes on the lower die component 3, and two fixing rods 24 are connected to the calibration plate 21. The fixing rods 24 are inserted into the fixing holes to fix the calibration component 2.

[0043] The position where the fixing holes are provided on the lower die component 3 is set on the center line when the spade plate 7 is placed on the lower die component 3.

[0044] Move the first limiting block 11 until the first limiting surface 111 of the first limiting block 11 abuts against the first calibration surface 221 of the first calibration block 22, and the second limiting surface 112 of the first limiting block 11 abuts against the second calibration surface 222 of the first calibration block 22; Specifically, move the first limiting block 11 along the third direction C or the fourth direction D until the first limiting surface 111 of the first limiting block 11 abuts against the first calibration surface 221 of the first calibration block 22; Move the first limiting block 11 along the first direction A or the second direction B until the second limiting surface 112 of the first limiting block 11 abuts against the second calibration surface 222 of the first calibration block 22.

[0045] Move the second limiting block 12 until the second limiting block 12 abuts against the second calibration block 23; Fasten the first limiting block 11 and the second limiting block 12.

[0046] By setting the calibration component 2, when stamping and marking spade plates 7 of different types and sizes, different calibration components 2 are replaced to adjust the position of the limiting component 1, thereby facilitating the adjustment of the position of the limiting component 1, improving work efficiency, and ensuring stamping quality.

[0047] A method for producing a spade plate includes the following steps: Cut the raw material and cut it into sheet materials according to the size of the spade plate 7; Use a steel stamper to stamp and mark the spade plate 7; Put the stamped and marked spade plate 7 into a heating furnace for high-temperature softening; Flip the spade plate 7 after high-temperature softening; Stamp and press the flipped spade plate 7 and simultaneously roll the pants; Perform heat treatment on the pressed and rolled spade plate 7.

[0048] By advancing the stamping and marking process, only two spade plates after heating are required for heat treatment, saving the process time and the time in the intermediate transfer process, ensuring the temperature of the spade plate during heat treatment, and thus ensuring the quality of the spade plate after heat treatment.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here.
