[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, 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 effort are within the scope of protection of the present invention.

[0058] The terms "first," "second," etc., used in the specification and claims of this invention are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0059] The following is combined with Figures 1 to 14 The bending machine mold provided in this invention will be described in detail through specific embodiments and application scenarios.

[0060] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0061] According to an embodiment of the present invention, a bending machine mold is used for mounting on a bending machine, the bending machine including a base 200 and a connecting plate 300, and the bending machine mold including a lower mold assembly 10 and an upper mold assembly.

[0062] Specifically, such as Figures 1 to 3 As shown, the lower mold assembly 10 is used to be installed on the base 200. The installation states of the lower mold assembly 10 on the base 200 include a first state and a second state. The upper mold assembly includes a first upper mold 20 and a second upper mold 30. When the lower mold assembly 10 is in the first state, the first upper mold 20 is installed on the connecting plate 300 and is set correspondingly to the lower mold assembly 10 in the first state. The first upper mold 20 cooperates with the lower mold assembly 10 in the first state to process the first workpiece 1. When the lower mold assembly 10 is in the second state, the second upper mold 30 is installed on the connecting plate 300 and is set correspondingly to the lower mold assembly 10 in the second state. The second upper mold 30 cooperates with the lower mold assembly 10 in the second state to process the second workpiece 2.

[0063] In other words, different installation methods of the lower mold assembly 10 on the base 200 result in different forms of the lower mold assembly 10 on the base 200. There are two types of upper molds, each corresponding to a different form of lower mold assembly 10. The upper molds and the corresponding forms of lower mold assemblies 10 form a combination, facilitating the processing of different workpieces. For example, when the lower mold assembly 10 is assembled into a forming groove 114 capable of bending a tubular structure, a first upper mold 20 with a corresponding tubular mold groove is selected to cooperate with it for bending the tubular workpiece. When the lower mold assembly 10 is assembled into a gap 115 structure, an upper mold with the corresponding structure is selected to cooperate with it for bending a plate-shaped workpiece. In other words, the bending machine mold according to the embodiments of the present invention utilizes the structural transformation of the lower mold assembly 10 to the greatest extent, enabling the lower mold assembly 10 to be applicable to two working conditions without the need to develop two different lower mold assemblies separately, greatly reducing the cost of mold development and expanding product functionality.

[0064] Therefore, the bending machine mold according to the embodiment of the present invention can process different workpieces by combining the lower mold assembly 10 in different states with different upper molds. Under the premise of minimizing the increase in mold development costs, the function of the mold is expanded and the forming requirements of various engineering vehicle prototypes are met.

[0065] According to one embodiment of the present invention, such as Figure 2 As shown, the lower mold assembly 10 includes two sub-molds 11. Each sub-mold 11 is formed as a rectangular block extending along the length of the base 200. A plurality of semi-forming grooves are provided on the first surface 111 of the sub-mold 11 facing away from the base 200. These semi-forming grooves extend from the first surface 111 to the second surface 112 of the sub-mold 11 perpendicular to the base 200, but do not extend to the third surface 113 of the sub-mold 11 perpendicular to the base 200. In the first state, the second surfaces 112 of the two sub-molds 11 are arranged adjacently so that the corresponding semi-forming grooves combine to form a forming groove 114. A plurality of protrusions 21 are provided on one side of the first upper mold 20. The protrusions 21 cooperate with the forming groove 114 to process the first workpiece 1. Figure 3 As shown, in the second state, the third surfaces 113 of the two sub-molds 11 are arranged opposite each other so that a gap 115 is defined between the third surfaces 113; the second upper mold 30 is a pressure block, which cooperates with the gap 115 to process the second workpiece 2.

[0066] In other words, the sub-mold 11 is provided with a semi-forming groove. When the two sub-molds 11 are installed in different ways, a forming groove 114 or a gap 115 can be defined, such as... Figures 4 to 8As shown, the forming groove 114 cooperates with the first upper mold 20 with protrusions 21 to bend steel pipes or round steel or process reinforcing ribs with bent structures. Compared with the traditional technology of manually bending or manually making reinforcing ribs, the samples processed in this application are less prone to deformation, and multiple samples can be processed simultaneously. Figures 9 to 14 As shown, the gap 115 formed by the two sub-molds 11 can be bent into a flange by cooperating with the block-shaped second upper mold 30, thereby improving functionality.

[0067] Preferably, the first workpiece 1 includes a tubular workpiece; the forming groove 114 is provided with a lower tubular groove bent toward the direction of the base 200, and the protrusion 21 is provided with an upper tubular groove bent toward the direction of the base 200. When the protrusion 21 cooperates with the forming groove 114, the upper and lower tubular grooves are used to clamp and bend the tubular workpiece.

[0068] Specifically, bending steel pipes and round steel bars requires specialized bending equipment. Existing bending machines cannot perform multiple functions simultaneously, resulting in high costs for processing different samples. For example... Figure 8 As shown, the bending machine according to the embodiment of the present invention can have the function of bending steel pipes or round steel according to specific needs, and the bending angle can be designed according to the needs. For example, when the sub-mold 11 is in the first state, the two sub-molds 11 are combined to form two forming grooves 114 with different bending angles, so as to process round steel or steel pipes with different bending angles.

[0069] Furthermore, the first workpiece 1 includes a plate-shaped workpiece; such as Figure 1 As shown, the forming groove 114 has at least one protrusion that protrudes in the direction opposite to the base 200, and the protrusion 21 has at least one recess that is recessed in the direction opposite to the base 200. When the protrusion 21 is engaged with the forming groove 114, the protrusion and the corresponding recess are used to process reinforcing ribs at the bending points of the plate-shaped workpiece.

[0070] In other words, the bending machine mold according to the embodiments of the present invention can also process different reinforcing ribs on sheet metal samples. In order to meet the requirement of making reinforcing ribs at the R-angle position of the workpiece, the prior art of manually making reinforcing ribs can easily lead to different degrees of deformation of the workpiece. According to the bending machine mold of the embodiments of the present invention, one or two protrusions are provided in the forming groove 114 with the same R-angle as the workpiece, and then a protrusion 21 with one or two recesses corresponding to the forming groove 114 is selected. The protrusion 21 cooperates with the corresponding forming groove 114. Thus, one or two reinforcing ribs can be processed on the workpiece to meet different user needs, and the processed workpiece has a uniform structure and accurate dimensions.

[0071] Preferably, the second workpiece 2 includes a plate-shaped workpiece with a flange; the gap 115 is formed as a rectangular gap 115, and the pressure block is formed as a rectangular block, and the pressure block is pressed into the gap 115 for bending the plate-shaped workpiece with the flange.

[0072] Existing bending equipment can only flange one side of a sample. If the flange is long, it easily interferes with the upper die of the bending machine, resulting in incomplete flange angle. In the prior art, to solve the problem of deformation of ultra-long parts caused by interference between the upper die and the flange of ultra-long parts, it is necessary to design two part structures first and then weld them together. However, this processing method is prone to welding deformation problems. According to the bending machine die of the present invention, when flange and bend longer parts, it will... Figure 2 The 11 sub-molds in the middle were swapped and installed to Figure 3 In the current state, adjust the gap 115 between the two sub-molds 11 to match the machining dimensions of the workpiece, such as... Figure 13 and Figure 14 As shown, the workpiece is placed on the gap 115 and pressed into the gap 115 by the pressure block, thereby achieving ultra-long flange shaping. According to the embodiment of the present invention, the bending machine mold can achieve one-time forming of the workpiece, resulting in higher workpiece strength and smoother appearance lines.

[0073] Furthermore, by combining the bending machine mold with the pressing function of the CNC programming of the bending equipment according to embodiments of the present invention, functions such as ultra-long flanging and shaping, bending of steel pipes or round steel, and rapid forming of reinforcing ribs for prototypes can be achieved. Based on this, small-batch prototypes with different bending angles or structures can also be produced to meet various product design needs.

[0074] like Figure 1 As shown, the bending machine according to a second aspect embodiment of the present invention includes a base 200, a connecting plate 300, and a bending machine mold as described in the above embodiment.

[0075] Specifically, the lower mold assembly 10 is mounted on the base 200, and the upper mold is mounted on the connecting plate 300. Since the mold for the bending machine according to the embodiment of the invention has multiple functions and can meet different operating conditions, the bending machine with the mold for the bending machine also has multiple functions and can meet different operating conditions.

[0076] By combining the lower mold assembly 10 in different states with different upper molds, different workpieces can be processed. This expands the mold function and meets the molding requirements of various engineering vehicle prototypes without increasing the mold development cost as much as possible.

[0077] According to one embodiment of the present invention, such as Figures 1 to 3As shown, the lower mold assembly 10 includes two sub-molds 11. Each sub-mold 11 is formed as a rectangular block extending along the length of the base 200. A plurality of forming grooves 114 are provided on the first surface 111 of the sub-mold 11 facing away from the base 200. The forming grooves 114 extend from the first surface 111 to the second surface 112 of the sub-mold 11 perpendicular to the base 200, but do not extend to the third surface 113 of the sub-mold 11 perpendicular to the base 200. The sub-mold 11 is provided with a plurality of first mounting holes (not shown) that extend along its thickness direction. The base 200 is provided with a plurality of second mounting holes 116 that correspond to the first mounting holes. The bending machine also includes bolts 400, which connect the first mounting holes and the second mounting holes 116 to fix the sub-mold 11 to the base 200.

[0078] In other words, the sub-mold 11 is placed on the base 200 in different forms and fixed to the base 200 by bolts 400. The bolt connection method is easy to disassemble.

[0079] Preferably, the first mounting hole and the second mounting hole 116 are respectively formed as elongated holes extending along the width direction of the base 200. That is, when performing flanging, shaping and bending on a large workpiece, the gap 115 between the two sub-molds 11 can be adjusted according to the processing requirements. In order to facilitate fixing the sub-molds 11 at different positions, the first mounting hole and the second mounting hole 116 are designed as elongated holes extending along the width direction of the base 200.

[0080] According to one embodiment of the present invention, such as Figure 1 As shown, the bending machine also includes multiple adjusting seats 500 and multiple adjusting rods 600. The adjusting seats 500 are fixed on two edges of the base 200 along its length. The adjusting seats 500 are provided with adjusting holes facing the corresponding sub-mold 11. One end of the adjusting rod 600 is provided with an adjusting handle 700, and the other end passes through the corresponding adjusting hole to stop against the corresponding sub-mold 11.

[0081] Specifically, the adjusting rod 600 is fixed by the adjusting seat 500. A scale can be set on the adjusting rod 600. The gap 115 between the two sub-molds 11 can be adjusted by adjusting the adjusting rod 600, so that the gap 115 can meet the processing requirements of the workpiece.

[0082] Preferably, the base 200 has an adjustment seat 500 at each end of its two edges along its length, and a total of four adjustment seats 500 are provided. The four adjustment seats 500 can maintain the stability during the adjustment of the gap 115.

[0083] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
