Description

Technical Field

[0001] The invention relates to the technical field of railway transportation material processing, and in particular to an integrated reinforcing seat complex, a mold and a reinforcing seat manufacturing method. Background Art

[0002] The reinforcement seat of a railway freight car is a component used to enhance the structural strength and stability of the freight car. In rail transportation, freight cars need to withstand various loads, including static loads (such as cargo weight) and dynamic loads (such as impact and vibration during driving). In order to ensure the safety and durability of the vehicle, reinforcement seats are installed at key positions of the vehicle body to provide additional support. Reinforcement seats are usually made of high-strength materials, such as steel. They can be welded to the vehicle body or installed by bolts or other fixing methods. The location of the reinforcement seat is usually the part of the vehicle that is subject to the greatest force, such as the bottom of the car body, the side wall connection, etc., to ensure that these key areas can effectively disperse and resist external pressure and impact.

[0003] Due to the differences in key areas, the required reinforcement seats have different sizes and structures, so currently there are three types of reinforcement seats with different structural sizes in the same railway freight car. Figure 1 As shown, Figure 1 From left to right, the first reinforcement seat 11, the second reinforcement seat 21 and the third reinforcement seat 31 required on a railway freight car are respectively shown. The first reinforcement seat 11 and the third reinforcement seat 31 need to be bent twice respectively, and the bending directions of the sides of the first reinforcement seat 11 and the third reinforcement seat 31 are different. The second reinforcement seat 21 needs to be bent three times, and both sides need to be bent. The sizes of the flat plates of the first reinforcement seat 11 and the second reinforcement seat 21 are different, and the sizes of the flat plates of the third reinforcement seat 31 and the second reinforcement seat 21 are different.

[0004] In the prior art, due to the different sizes and bends of the reinforcement seat, the production is based on the blanking of steel plates, and the plates are bent by a bending machine. Since the production standards of the reinforcement seat have high requirements for its bending degree, when the reinforcement seat is made by the bending process, it is easy to have insufficient bending degree, and then it is necessary to fill the material. The production scheme of the prior art is suitable for making different types of reinforcement seats, but when the bending process is performed, extra plates must be used, otherwise it cannot be made, and the amount of the reinforcement seat is large (16 pieces are required for each car), which requires more waste of materials. At the same time, when the existing production method is used to make the reinforcement seat, only one reinforcement seat can be made at a time. In the same railway freight car, at least dozens of reinforcement seats are required. If the existing technology is used for production, the number of bending and filling materials is as high as dozens of times, the overall production efficiency is low, the production is slow, and the utilization rate of the plate is low. Summary of the invention

[0005] The first solution provides an integrated reinforcement seat complex, which is used to improve production efficiency and save plate materials.

[0006] An integrated reinforcement seat complex comprises a first cutting assembly, a second cutting assembly and a third cutting assembly; the first cutting assembly comprises a plurality of first reinforcement seats, the second cutting assembly comprises a plurality of second reinforcement seats, and the third cutting assembly comprises a plurality of third reinforcement seats; the first reinforcement seat, the second reinforcement seat and the third reinforcement seat are used to meet all requirements for the type and quantity of reinforcement seats on a railway freight car; the three types of reinforcement seats are connected into a strip-shaped whole by three cutting assemblies; the assemblies are connected by cutting lines, wherein the cutting line between the first cutting assembly and the second cutting assembly is arranged between adjacent sides of the two assemblies; and the cutting line between the second cutting assembly and the third cutting assembly is arranged between adjacent sides of the two assemblies.

[0007] Beneficial effects: Although the prior art uses a bending machine to make a reinforcement seat, the structure of the reinforcement seat complex has multiple bends, and the bending directions are not consistent, so it is impossible to use a bending machine to make it. In addition, technicians in this field either improve the method of making a reinforcement seat with a bending machine, or change the method of making a reinforcement seat to directly obtain the reinforcement seat, but do not think of first making a reinforcement seat complex and then cutting the reinforcement seat complex to obtain a separate reinforcement seat. This not only adds an extra production process, which easily increases the time for making the reinforcement seat, but also the bending directions of each reinforcement seat are different, and even the size and structure are different, making it difficult to make an integrated reinforcement seat complex.

[0008] This solution is different. A railway train needs three different reinforcement seats, namely the first reinforcement seat, the second reinforcement seat and the third reinforcement seat. The three different reinforcement seats are made into an integrated reinforcement seat complex. This is because although the bending directions of the first reinforcement seat and the third reinforcement seat are different, the bending angles are the same and the sizes are the same. Both sides of the second reinforcement seat need to be bent, and the bending angles and sizes are different from those of the first reinforcement seat and the second reinforcement seat. In the production of this reinforcement seat complex, the number of the first reinforcement seat, the second reinforcement seat and the third reinforcement seat required on a railway train is known in advance, and then the type of reinforcement seat is confirmed by the position of the through hole setting on the steel plate blank in advance by drawing and engraving, and then all the reinforcement seats on a whole railway freight car are directly made, and all the reinforcement seats are directly made into a reinforcement seat complex. For example, the upper plate and a bent side plate adjacent to the upper plate are used as the first reinforcement seat or the third reinforcement seat, and the lower plate and two adjacent bent side plates are used as the second reinforcement seat. Alternatively, the upper plate and two adjacent bent side plates can be used as the second reinforcement seat. This can be made in advance by drawing and engraving. This is highly flexible, and only one reinforcement seat complex needs to be designed to integrate all the reinforcement seats required for a whole railway train into a reinforcement seat complex, which has high applicability. In this way, when producing all the reinforcement seats on a railway train, the production speed is faster and more material is saved. Compared with the prior art, this solution makes a reinforcement seat complex and then makes a separate reinforcement seat. It is 60% faster than directly using a bending machine to make a separate reinforcement seat, and saves about 10% of the raw materials.

[0009] Preferably, one end of the first cutting assembly is connected to one end of the second cutting assembly via a cutting line; the other end of the second cutting assembly is connected to the third cutting assembly via a cutting line.

[0010] Beneficial effects: The positions of the first cutting assembly, the second cutting assembly and the third cutting assembly are set, and the second cutting assembly is located between the first cutting assembly and the third cutting assembly. After cutting the rear reinforcement seat complex, it is easy to take out different types of reinforcement seat complexes. At the same time, this is also set according to the manufacturing method to obtain different numbers of reinforcement seats.

[0011] Preferably, the first cutting assembly has 2 first reinforcement seats, the second cutting assembly has 12 second reinforcement seats, and the third cutting assembly has 2 third reinforcement seats; each reinforcement seat is connected by a cutting line; the second reinforcement seat located at one end of the second cutting assembly, the second reinforcement seat is connected to the first reinforcement seat by a cutting line at the bent side close to the first reinforcement seat; the second reinforcement seat located at the other end of the second cutting assembly, the second reinforcement seat is connected to the third reinforcement seat by a cutting line at the bent side close to the third reinforcement seat.

[0012] Advantageous effect: All types and quantities of reinforcements for a railway freight car are available in one integrated reinforcement complex.

[0013] Preferably, the cutting line is a cutting strip, which is semi-cylindrical, and the cutting strip is equal to and flush with the bent side of each reinforcement seat; one side of the cutting strip is fixedly connected to a reinforcement seat, and the other side of the cutting strip is fixedly connected to another reinforcement seat.

[0014] Beneficial effect: The cutting strip is arranged between the bent upper side plate and the bent lower side plate. By cutting the semi-cylindrical cutting strip, different reinforcement seats can be obtained by simply cutting the cutting strip along the axial direction of the cutting strip. This not only speeds up the speed of obtaining a single reinforcement seat after cutting the reinforcement seat complex, but also ensures that the size of each different reinforcement seat is within the error range of the standard size.

[0015] Preferably, the cutting strip is convex relative to the bent side edges of two adjacent reinforcing seats, and the thickness of the cutting strip is at least 2 mm thicker than the reinforcing seats.

[0016] Beneficial effect: The thickness of the cutting strip is 2mm, which not only facilitates the rapid positioning of the cutting machine, but also enables the cutting of different reinforcement seats. Even if there are extra cutting strips on the side of the reinforcement seat, it can be within the error range of the reinforcement seat standard parts, thus ensuring that the structural dimensions of the reinforcement seat meet the standards.

[0017] Preferably, the cutting line is a cutting long block, which has a rectangular structure, and the thickness of the cutting long block is the same as the thickness of the reinforcement seat; one side of the cutting long block is fixedly connected to a reinforcement seat, and the other side is fixedly connected to another reinforcement seat; a cutting groove is provided in the cutting long block, the axis of the cutting groove is colinear with the axis of the cutting long block, and the axis is parallel to the bent side of the reinforcement seat.

[0018] Beneficial effect: A cutting groove is also provided, and the setting of the cutting groove can reduce the redundant cutting long blocks on the bending side of the reinforcement seat, so that the excess part of the reinforcement seat can be minimized.

[0019] The second scheme provides a mold for making an integrated reinforcement seat complex described in the first scheme, including an upper mold and a lower mold; the lower mold includes an upper template, a lower template, a side template, an upper convex bending template and a lower convex bending template; the left end of an upper template is connected to one end of a side template, and the other end of the side template is connected to the lower template; the upper template is higher than the lower template; the head of the lower template is fixedly connected to the lower convex bending template; the left end of the lower template is fixedly connected to one end of another side template, and the other end of the other side template is fixedly connected to another upper template.

[0020] Beneficial effect: The mold is a press mold, and by using the mold to press the steel plate to obtain an integrated reinforcement seat complex, the integrated reinforcement seat complex can be produced quickly and material-savingly.

[0021] Preferably, the upper end of the upper mold is provided with a first upper fillet, the first upper fillet is α, α=R29mm, the bottom of the upper mold is provided with a first chamfer, the first chamfer is β, β=R29mm; the draft angle of the upper mold is θ, θ=7°.

[0022] The third scheme provides a method for manufacturing a reinforcement seat, which is applied to an integrated reinforcement seat complex described in the first scheme, and to a mold described in the second scheme, and includes the following steps: S1, using a laser machine to cut the steel plate and the through hole; S2, placing the steel plate into the mold for press forming to obtain a reinforcement seat complex; S3, using a cutting machine to cut along the cutting strip to obtain a single reinforcement seat.

[0023] Beneficial effect: By manufacturing different types of reinforcement seats of all required quantities on a railway train through three processes, different individual reinforcement seats can be obtained, which has higher production efficiency and saves more materials.

In this embodiment, the cutting line is a cutting strip, the cutting strip is semi-cylindrical, and the length of the cutting strip and the bending side of each reinforcement seat is equal and flush; one side of the cutting strip is fixedly connected to a reinforcement seat, and the other side of the cutting strip is fixedly connected to another reinforcement seat. The cutting strip is convex relative to the bent side edges of two adjacent reinforcing seats, and the thickness of the cutting strip is at least 2 mm thicker than the reinforcing seats.

[0045] like Figure 3 and Figure 4 As shown, an integrated reinforcement seat complex is described in terms of structural features, including multiple upper flat plates 4, multiple upper convex bent plates 41, multiple bent side plates 6, multiple lower flat plates 5, and multiple lower convex bent plates 51. In this embodiment, there are a total of 4 upper flat plates 4, 4 upper convex bent plates 41, 6 bent side plates 6, 3 lower flat plates 5, and 3 lower convex bent plates 51. It should be understood that the description of an integrated reinforcement seat complex in terms of structural features is a more specific description and explanation of the various reinforcement seats in the first cutting assembly 1, the second cutting assembly 2, and the third cutting assembly 3.

[0046] Specifically, the tail end of an upper flat plate 4 is fixedly connected to the upper convex bending plate 41, the left end of an upper flat plate 4 is connected to the upper end of the bending side plate 6, the lower end of the bending side plate 6 is connected to the right end of the lower flat plate 5, the head end of the lower flat plate 5 is connected to the lower convex bending plate 51, the left end of the lower flat plate 5 is connected to the lower end of another bending side plate 6, and the upper end of the other bending side plate 6 is connected to another upper flat plate 4. Two first through holes 42 are formed on the upper flat plate 4, and the first through holes 42 are close to the bending side plate 6 and away from the upper convex bending plate 41. Two groups of second through holes 52 are formed on the bending side plate 6, each group has two second through holes 52, and the two groups of second through holes 52 are located at different ends of the bending side plate 6 and are symmetrical with the center of the bending side plate 6. Two groups of third through holes 63 are formed on the lower plate 5 , each group has two third through holes 63 , the third through holes 63 are far away from the lower convex bending plate 51 , and the two groups of third through holes 63 are symmetrical about a symmetry axis parallel to the length direction of the lower plate 5 .

[0047] like Figure 4 As shown, each bent side panel 6 is composed of a bent upper side panel 61 and a bent lower side panel 62, wherein the bent upper side panel 61 is close to the upper flat plate 4, and the bent lower side panel 62 is close to the lower flat plate 5. A cutting strip 64 is also provided on the bent side panel 6, wherein one end of the cutting strip 64 is fixedly connected to the bent upper side panel 61, and the other end is fixedly connected to the bent lower side panel 62. In the present embodiment, the cutting strip 64 is convex relative to the bent upper side panel 61 and the bent lower side panel 62, and the cutting strip 64 is linear and may be presented as a semi-cylindrical structure. The radius of the bottom surface of the cutting strip 64 is 2 mm, which is equivalent to the thickness of the cutting strip 64. In other embodiments, the cutting strip 64 may also be concave and linear, and its concave shape may be a semi-cylindrical structure.

[0048] Specifically, Figure 5As shown, the bent upper side plate 61 includes a bent upper side sub-plate 611 and an upper convex sub-plate 612. The bent lower side plate 62 includes a bent lower side sub-plate 621 and a lower concave sub-plate 622. The bent upper side sub-plate 611 is in the shape of a triangular flat plate, and its longest side is fixedly connected to one end of the cutting strip 64. The bent lower side sub-plate 621 is in the shape of a triangular flat plate, and its longest side is fixedly connected to the other end of the cutting strip 64. The head end of the cutting strip 64 is flush with the end of the bent upper side sub-plate 611 with the smallest angle, and the tail end of the cutting strip 64 is flush with the end of the bent lower side sub-plate 621 with the smallest angle, that is, the axis of the cutting strip 64 passes through the ends of the bent upper side sub-plate 611 and the bent lower side sub-plate 621 with the smallest angle. In this way, by cutting along the cutting strip 64, the bent upper sub-plate 611 and the bent lower sub-plate 621 can be quickly and accurately cut out. A group of second through holes 52 is provided on the bent upper sub-plate 611, and another group of second through holes 52 is provided on the bent lower sub-plate 621. The bent upper sub-plate 611 is fixedly connected to one end of the upper convex sub-plate 612, and the other end of the upper convex sub-plate 612 is fixedly connected to the upper flat plate 4. The bent lower sub-plate 621 is fixedly connected to one end of the lower concave sub-plate 622, and the other end of the lower concave sub-plate 622 is fixedly connected to the lower flat plate 5.

[0049] In the description of this embodiment, the first cutting assembly 1 is located at the left end, the second cutting assembly 2 is located in the middle, and the third cutting assembly 3 is located at the right end. The first cutting assembly 1 has a total of 1 first reinforcement seat 11, the second cutting assembly 2 has a total of 5 second reinforcement seats 21, and the third cutting assembly 3 has a total of 1 third reinforcement seat 31. Figure 4 The upper flat plate, the bent upper side plate and the upper convex bent plate at the far left constitute a first reinforcement seat 11, and the upper flat plate, the bent upper side plate and the upper convex bent plate at the far right constitute a third reinforcement seat 31. The remaining upper flat plate, the lower flat plate, the bent upper side plate, the bent lower side plate, the upper convex bent plate and the lower convex bent plate constitute five second reinforcement seats 21. Moreover, the upper convex bent plate and the lower convex bent plate are both the bent top edges of the reinforcement seat.

[0050] In this embodiment, a cutting machine is used to cut along the cutting strip 64, and the upper side plate 61, the upper convex bending plate 41 and the upper flat plate 4 are bent to form the first reinforcement seat 11 or the third reinforcement seat 31. The two bent lower side plates 62, the lower flat plate 5 and the lower convex bending plate 51 located at the left and right ends of the lower flat plate 5 form the second reinforcement seat 21. The main difference between the first reinforcement seat 11 and the third reinforcement seat 31 is that the bending directions of the two are different. After cutting, Figure 2As shown, a reinforcement seat complex has one first reinforcement seat 11, five second reinforcement seats 21 and one third reinforcement seat 31. One end of the first reinforcement seat 11 is fixedly connected to one end of a group of second reinforcement seats 21, and the other end of a group of second reinforcement seats 21 is fixedly connected to one end of the third reinforcement seat 31. There are five second reinforcement seats 21 in a group of second reinforcement seats 21. Specifically, Figure 2 and Figure 4 Combined with the shown Figure 4 In the figure, the upper flat plate 4, the upper convex bent plate 41 and the upper bent side plate 61 on the far right form a first reinforcement seat 11, and the upper flat plate 4, the upper convex bent plate 41 and the upper bent side plate 61 on the far left form a third reinforcement seat 31. In addition, the remaining plates are combined to form five second reinforcement seats 21.

[0051] The first reinforcement seat 11 and the third reinforcement seat 31 need to be bent twice, and the second reinforcement seat 21 needs to be bent three times. Specifically, the top and one side of the first reinforcement seat 11 and the third reinforcement seat 31 need to be bent. The difference between the two in structure is that the left side of the first reinforcement seat 11 needs to be bent, and the right side of the third reinforcement seat 31 needs to be bent. The top and both sides of the second reinforcement seat 21 need to be bent. In the current railway freight cars, each railway freight car requires a total of 16 reinforcement seats, of which the first reinforcement seat 11 requires 2 pieces, the second reinforcement seat 21 requires 12 pieces, and the third reinforcement seat 31 requires 2 pieces. A railway freight car needs to be bent up to 44 times. If the existing technology is used to make the reinforcement seat, the number of bends is large and the production efficiency is low. At the same time, the existing technology cannot produce a reinforcement seat complex, because the reinforcement seat complex is characterized by a "one concave and one convex" structure, and the current bending machine is difficult to make a reinforcement seat complex. Then, even if the steel plate is bent multiple times by a bending machine, the steel plate undergoes a certain deformation due to the influence of the previous bending. When the steel plate is bent for the next time, due to the deformation of the steel plate, in order to ensure the consistency of the bending angle each time, the bending force of the bending machine needs to change, that is, the bending force is different each time, and it is more difficult to produce a reinforcement seat complex. Therefore, in the production of existing reinforcement seats, based on the limitations of the production method, most technicians only consider how to make a single reinforcement seat faster and more efficiently under the current production method, or change the production method to make a single reinforcement seat faster and more efficiently. If multiple reinforcement seats are made into a reinforcement seat complex, there will be an extra cutting step. Only by cutting the reinforcement seat complex can a single reinforcement seat be obtained, and in the cutting step, how to perform precise cutting, that is, the design of the cutting position needs to not affect the quality of the single reinforcement seat, and the cutting position is also easy to identify, so as to achieve fast cutting and directly form a single complete reinforcement seat after cutting without the need for refilling. Therefore, it is difficult for existing technicians to think of changing the manufacturing method of the reinforcement seat and forming a plurality of reinforcement seats into a reinforcement seat complex and then cutting to obtain a single reinforcement seat. Compared with directly obtaining a single reinforcement seat, this requires more steps, and the additional steps also need to consider how to ensure the integrity and quality of the single reinforcement seat. Even if more steps are added, a single reinforcement seat can be produced faster and more efficiently than the ordinary existing manufacturing method.

[0052] The existing manufacturing methods, such as bending directly with a bending machine, cannot be used, and technicians will not consider cutting the first reinforcing seat 11, the second reinforcing seat 21 and the third reinforcing seat 31 after they are integrated into one. This is because the first reinforcing seat 11, the second reinforcing seat 21 and the third reinforcing seat 31 are ultimately required to be separate. After they are integrated into one, more cutting processes are required. Adding more processes means increasing production time and production energy consumption, and precise cutting is required to ensure the structural dimensions of each reinforcing seat. Therefore, technicians will only consider how to change the manufacturing method or improve the manufacturing method to obtain separate reinforcing seats more quickly. However, this embodiment is different. This embodiment provides a reinforcing seat complex, which integrates various types of reinforcing seats and then cuts out different types of reinforcing seats. Specifically, each reinforcement seat complex has a large number of reinforcement seats of different types. The reinforcement seat complex formed by a large number of reinforcement seats of different types is first obtained at one time, and then they are cut one by one to obtain a plurality of individual reinforcement seats of different types, so that the number of reinforcement seats required for a railway freight car is completed at one time. This is suitable for batch production of the reinforcement seats required for a railway freight car as a batch, which has higher production efficiency and faster speed.

[0053] Secondly, a reinforcement seat complex is first made, and then different types of reinforcement seats are obtained after cutting. Compared with the prior art method of using a bending machine to bend and fill materials, its production is more material-saving.

[0054] Moreover, the setting of the cutting strip 64, the axis of the cutting strip 64 is equivalent to the dividing line between the second reinforcement seat 21 and other types of reinforcement seats. Specifically, after cutting along the cutting strip 64, the reinforcement seat is obtained, and the edge of the reinforcement seat is the residual cutting strip 64. Since the thickness of the complete cutting strip 64 is only 2mm, the thickness of the residual cutting strip 64 is generally half of the thickness of the complete cutting strip 64 or even less. Even in the case of adding the residual cutting strip 64, the size of the cut reinforcement seat can be within the allowable error range. Moreover, in the production of the reinforcement seat, the bending degree and the position of the through hole of the reinforcement seat are more important. The more the bending degree of the reinforcement seat meets the standard, the better the adhesion between the reinforcement seat and the part of the vehicle that is subjected to the greatest force, and the smaller the friction. Even if a tiny cutting strip 64 remains on the edge of the reinforcement seat, it only affects the appearance of the reinforcement seat, and does not affect the actual function of the reinforcement seat.

[0055] Finally, the position of the cutting strip 64 is set so that the axis of the cutting strip 64 is used as the dividing line between the bent upper sub-plate 611 and the bent lower sub-plate 621. This is because, compared with the upper convex sub-plate 612 and the lower concave sub-plate 622, the bending degrees of the bent upper sub-plate 611 and the bent lower sub-plate 621 are smaller and closer. The cutting strip 64 is provided between the bent upper sub-plate 611 and the bent lower sub-plate 621, so that different reinforcement seats can be accurately cut out. In addition, the cutting strip 64 is designed as a semi-cylindrical straight line, so that different reinforcement seats can be quickly obtained in one cutting. Example 2

[0056] Different from the first embodiment, in this embodiment, the cutting line between the two reinforcement seats is a cutting long block, the cutting long block has a rectangular structure, and the thickness of the cutting long block is the same as the thickness of the reinforcement seat; one side of the cutting long block is fixedly connected to a reinforcement seat, and the other side is fixedly connected to another reinforcement seat; a cutting groove is provided in the cutting long block, the axis of the cutting groove is colinear with the axis of the cutting long block, and the axis is parallel to the bent side of the reinforcement seat.

[0057] Specifically, the longest side of the bent upper sub-plate 611 is fixedly connected to the other end of the cutting long block. The head end of the cutting long block is flush with the end of the bent upper sub-plate 611 with the smallest angle, and the tail end of the cutting long block is flush with the end of the bent lower sub-plate 621 with the smallest angle, that is, the longest axis of the cutting long block passes through the ends of the bent upper sub-plate 611 and the bent lower sub-plate 621 with the smallest angle. In this way, by cutting along the cutting groove on the cutting long block, the bent upper sub-plate 611 and the bent lower sub-plate 621 can be cut quickly and accurately, thereby cutting out different reinforcement seats. In this embodiment, the thickness of the cutting groove is 2 mm, and the length of the cutting groove is 2 / 3 of the cutting long block.

[0058] The beneficial effects of this embodiment

[0059] Compared with setting cutting strips, setting cutting long blocks and corresponding cutting grooves can use a laser cutting machine to cut the cutting grooves when making the reinforcement seat. At the same time, the setting of the cutting grooves can reduce the remaining parts of the bent sides of different reinforcement seats after cutting, so as to reduce the error between the actual bent sides and the standard bent sides.

[0060] Embodiment 3

[0061] like Figure 6 and Figure 7 As shown, this embodiment provides a mold for making the reinforcing seat complex described in the above embodiment. The reinforcing seat complex can be specifically referred to in the above embodiment. A mold includes an upper mold and a lower mold.

[0062] Specifically, Figure 8 and Fig. 9As shown, the lower mold includes two upper mold plates 84, a lower mold plate 85, two side mold plates, four first cylinders 81, two upper convex bending mold plates 82 and a lower convex bending mold plate 83.

The head of the lower template 85 is fixedly connected to the lower convex bending template 83, and four first cylinders 81 are evenly arranged on the lower template 85 and are far away from the lower convex bending template 83. The left end of the lower template 85 is fixedly connected to one end of another side template, and the other end of the other side template is fixedly connected to another upper template 84.

[0063] The upper template 84 is used to shape the upper flat plate 4, the upper convex bending template 82 is used to shape the upper convex bending plate 41, the side template is used to shape the bent side plate 6, the lower template 85 is used to shape the lower flat plate 5, and the lower convex bending template 83 is used to shape the lower convex bending plate 51. The first cylinder 81 is used to locate the third through hole 63, that is, to locate the steel plate. In this embodiment, the steel plate is used as a blank to make the reinforcing seat complex.

[0064] like Figure 7 As shown, the upper end of the upper die is provided with a first upper fillet, the first upper fillet is α, α = R29mm, and the bottom of the upper die is provided with a first chamfer, the first chamfer is β, β = R29mm. The upper die is in an inward draft shape, mainly used to tilt the bent side plate 6, and the draft angle of the upper die is θ, θ = 5°. By setting the chamfer and draft angle, the upper die can be driven by the press machine to press the steel plate into a reinforcement seat complex with a more accurate bending degree, without the need for a material filling step, thereby improving production efficiency.

[0065] like Figure 8 As shown, the upper end of the lower die is provided with a second chamfer, which can be made according to the first chamfer and the thickness of the steel plate, and is a conventional angle that is easily obtained by ordinary technicians. When the steel plate is pressed, the holding time can be selected according to the conventional holding time in the field, and the general holding time is 5-10s. The first upper fillet and the second chamfer are provided to make the upper convex sub-plate 612, and the first chamfer is provided to make the lower concave sub-plate 622.

[0066] like Fig. 9 As shown, the inner wall of the lower mold is fixedly connected with cutting templates 86 on both sides, and the cutting templates 86 are convex relative to the inner wall of the lower mold and are semi-cylindrical structures. In order to make the cutting strip 64 on the steel plate, the upper mold is based on the cutting template 86 set in the lower mold and can be set adaptively. The setting of the upper mold can be made according to the setting of the lower mold, which can be made by ordinary technicians based on experience.

Secondly, four first cylinders 81 are provided in the lower mold to locate the through holes punched out on the steel plate, so as to accurately press the reinforcing seat complex. In addition, a cutting template 86 is provided in the lower mold so that the reinforcing seat complex can be cut along the cutting strip 64 after being formed, so as to quickly obtain various types of reinforcing seats.

[0069] The contents described in this embodiment are briefly described. For matters not mentioned in the embodiment part, reference can be made to the corresponding contents in the aforementioned embodiments.

[0070] Embodiment 4

[0071] Different from the above-mentioned embodiment, this embodiment provides a method for manufacturing a reinforcement seat, which is applied to an integrated reinforcement seat complex in the above-mentioned embodiment, and a mold for manufacturing the reinforcement seat complex.

[0072] A method for manufacturing a reinforcing seat comprises: S1, cutting a steel plate and a through hole by a laser machine.

[0073] Specifically, a laser machine is used to laser cut the rectangular steel plate to cut a first schematic structure on the surface of the steel plate. The first schematic structure is to flatten the reinforcement seat complex, determine the overall shape of the reinforcement seat complex, and laser cut the first through hole 42, the second through hole 52 and the third through hole 63.

[0074] S2, placing the steel plate into a mold for pressing to obtain a reinforcing seat complex.

[0075] Specifically, the aforementioned steel plate refers to a steel plate that has been laser cut in a laser machine.

[0076] S3, placing the steel plate into a mold for pressing to obtain a reinforcing seat complex.

[0077] Specifically, the steel plate is placed in a mold for press forming, and after the press forming is completed, the pressure is maintained. After the pressure is maintained, the reinforcement seat complex that has not yet been cooled and formed is taken out of the mold and placed on a placement table for cooling. After the cooling is completed, the reinforcement seat complex is formed.

[0078] S4, using a cutting machine to cut along the cutting strip 64 to obtain a single reinforcing seat.

[0079] Specifically, a cutting machine is used to perform straight-line cutting along the cutting strip 64 to obtain various types of reinforcing seats, including a first reinforcing seat 11 , a second reinforcing seat 21 and a third reinforcing seat 31 .

In this test example, the reinforcement seats required for a railway freight car are used as the test object. The railway freight car of this model requires 16 reinforcement seats, of which 2 first reinforcement seats 11 are required, 12 second reinforcement seats 21 are required, and 2 third reinforcement seats 31 are required. That is, in the reinforcement seat manufacturing test, the reinforcement seats required for a railway freight car are regarded as the test quantity of a batch.

[0083] In the prior art, as described in the background of the specification, a bending machine is used to bend the steel plate, and a separate reinforcing seat is directly obtained after punching.
