Description

Technical Field

[0001] The present application belongs to the technical field of sheet metal processing, and in particular, relates to an adaptive processing mold. Background Art

[0002] In railway freight car products, due to structural design reasons, it is common to encounter grouped sheet metal parts, which include a basic shape part and parts with other features added on this basis, generally adding holes or adding gaps. Figure 1 , a fitting adds a hole to another fitting shape; e.g. Figure 2 , different numbers of notches are combined to form multiple accessories. The processing methods of the above-mentioned grouped sheets are:

[0003] 1. CNC cutting: Since similar accessories are usually special-shaped parts, CNC cutting can be used. The advantage of this method is that it is highly versatile and can process gaps of various sizes and shapes. The main disadvantage is that the cutting cost for mass production is high and the efficiency is low. It is suitable for small-batch production of multiple varieties.

[0004] 2. Multiple sets of die punching and blanking: Make a die for each shape, such as one set with holes, one set without holes, etc. The advantage of this method is that the die punching efficiency is high, and no additional die adjustment is required for punching each accessory. The disadvantage is that there are many dies, the cost is high, and the die management cost is increased. The die needs to be replaced or multiple devices need to be used to install the die at the same time for punching the same group of accessories with different characteristic shapes. It is suitable for ultra-large-scale production with stamping equipment and processing sites.

[0005] The above processing methods are not suitable for mass production and processing devices that can punch holes and grooves. The existing technology has improved the device of blanking and cutting with a single set of dies: a set of composite dies is made according to the shape containing the most features, and the upper die structure of the die corresponding to each characteristic shape is detachable, and accessories with different characteristic shapes are processed in batches, such as installing a round punch to process a batch of accessories with holes, then loosening the screws and disassembling the punch to process a batch of accessories without holes, and then installing the round punch to process accessories with holes. Although this method can solve the problem to a certain extent, the advantage is that the number of dies is small, and accessories with different characteristic shapes can be processed into groups, and the efficiency is higher than that of cutting and blanking, but there are still some disadvantages, such as the need to constantly adjust the upper die punch of the die to process accessories with different characteristic shapes, which is cumbersome to operate and affects the processing efficiency and quality stability. It is suitable for small batches of series accessories.

[0006] Therefore, the existing processing devices for metal grouped sheets are not suitable for mass production and processing of both hole-shaped and non-hole-shaped sheets. Summary of the invention

[0007] The present application aims to at least to some extent solve the technical problem of not being suitable for mass production and processing of both hole-shaped and non-hole-shaped plates. To this end, the present application provides an adaptive processing mold, which can be suitable for the processing of both hole-shaped and non-hole-shaped plates by quickly adjusting the device structure, and can be mass-produced with high processing efficiency. On the other hand, it can ensure processing quality and reduce processing costs.

[0008] The embodiment of the present application provides an adaptation processing mold, which includes:

[0009] The main body is provided with a drawing slot and an installation slot, and the drawing slot and the installation slot are connected to the main body;

[0010] A draw plate is matched with the draw slot, and the draw plate can be placed into or drawn out of the draw slot relative to the main body;

[0011] The punch includes a first end and a second end that are arranged opposite to each other. The first end is arranged in a mounting groove. The first end can move along a line connecting the first end and the second end in the mounting groove. The second end is used for punching the sheet material. The first end is used to abut against the drawing plate when the drawing plate is placed in the drawing groove, and to abut against the main body when the drawing plate is pulled out of the drawing groove, so as to adjust the stroke of the punch.

[0012] In some embodiments, the drawing groove and the installation groove are provided on different sides of the main body so that the thickness direction of the drawing plate is consistent with the moving direction of the punch.

[0013] In some embodiments, an insert is further included for placing the sheet material, and the insert is spaced apart from the main body and opposite to the punch.

[0014] In some embodiments, the thickness S of the draw plate is greater than the axial stroke e of the punch relative to the insert, and e is greater than the thickness of the sheet material.

[0015] In some embodiments, the mounting groove matches the punch, and the size of the first end is larger than the size of other positions of the mounting groove.

[0016] In some embodiments, the width of the drawing plate inserted into the drawing slot is greater than the outer diameter at the first end.

[0017] In some embodiments, the main body includes a mold body and a mounting seat, the mold body is used to connect to the output end of the punching machine, the mounting seat is fixed to the mold body, and the mounting seat is provided with a drawing groove and a mounting groove.

[0018] In some embodiments, a fixing member is further included, and the fixing member is used to connect the drawer plate to the main body when the drawer plate is completely placed in the drawer groove.

[0019] In some embodiments, a positioning member is further included, the mounting seat is provided with a positioning hole, and the positioning member is arranged in the positioning hole.

[0020] In some embodiments, a locking piece is further included, and the locking piece connects the mounting seat and the main body.

[0021] It can be seen from the above technical solution that the beneficial effects of this application are:

[0022] The present application forms two working modes through the combination of a drawer plate and a main body. When the drawer plate is inserted into the drawer groove, the first end of the punch can abut against the drawer plate, so that the second end can perform hole-shaped sheet material processing when the punch moves according to the stroke. When the drawer plate is pulled out of the drawer groove, the first end of the punch abuts against the main body, which is equivalent to the stroke that the punch needs to fill the drawer plate space. In this way, after the punch moves according to the stroke, the second end no longer punches holes, thereby forming a sheet material without holes. In this way, the present application is suitable for the processing of hole-shaped and sheet materials without holes by quickly adjusting the device structure, and can be mass-produced with high processing efficiency. On the other hand, it can ensure processing quality and reduce processing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Please refer to Figure 1, the embodiment of the present application provides an adaptive processing mold, which includes a main body 10, a drawing plate 20 and a punch 30, the main body 10 is connected to a driving device for processing, such as the top of the main body 10 is connected and fixed to a press, such as the connection between the press and the upper mold body 11, which is a conventional connection method, so that the position of the main body 10 can be adjusted by the press to achieve blanking processing; the main body 10 is provided with a drawing groove 101 and a mounting groove 102, the drawing groove 101 and the mounting groove 102 are connected to the main body 10, the drawing groove 101 and the mounting groove 102 have notches on the side of the main body 10, the shape and size of the drawing groove 101 match the drawing plate 20, and the shape and size of the mounting groove 102 match one end of the punch 30; the thickness of the drawing plate 20 matches the thickness of the drawing groove 101, so that the drawing plate 20 can move, the drawing plate 20 can be placed in or pulled out of the drawing groove 101 relative to the main body 10, and one end of the drawing plate 20 is completely located in the drawing groove 101 The other end of the draw plate 20 is located outside the draw groove 101; the punch 30 includes a first end and a second end that are arranged opposite to each other. For example, the punch 30 adopts an axial structure, and its top and bottom ends are respectively the first end and the second end. The first end is arranged in the mounting groove 102, and the first end can move along the connecting line between the first end and the second end in the mounting groove 102. When the punch 30 is not moving, the first end is completely in the mounting groove 102. When the draw plate 20 is pulled out, the first end can move to the draw groove 101. The second end is used for punching the sheet 80. The punch 30 moves along the stroke driven by the press, and the second end contacts and punches the sheet 80. The first end is used to abut against the draw plate 20 when the draw plate 20 is placed in the draw groove 101, and abut against the main body 10 when the draw plate 20 is pulled out of the draw groove 101, so as to adjust the stroke of the punch 30. In this way, under the same stroke of the main body 10, the punch 30 has two different strokes, so as to punch holes and grooves on the sheet 80. By quickly pulling out or inserting the draw plate 20, accessories with different features are formed, and adjustments are made quickly. Only through the draw plate 20, a single accessory, reliable, efficient and low-cost large-scale grouped accessories punching processing can be achieved; at the same time, the draw plate 20 can be made of the same material as the punch 30, which also avoids the problem of local force deformation caused by the hardness difference between the punch 30 and the main body 10.

[0036] The processing equipment of the prior art is not suitable for processing both hole-shaped and non-hole plates 80 during mass production. The prior art uses a composite mold, which can solve the problem of batch processing of hole-shaped and non-hole plates 80 to a certain extent. However, when the current processing equipment needs to switch between processing hole-shaped and non-hole plates 80, it is more complicated to adjust the mold, and the structure may be different after adjustment, resulting in low quality stability. The present application forms two working modes through the combination of the drawer plate 20 and the main body 10. When the drawer plate 20 is inserted into the drawing groove 101, the first end of the punch 30 can abut against the drawer plate 20, so that the second end can process the hole-shaped sheet material 80 when the punch 30 moves according to the stroke. When the drawer plate 20 is pulled out of the drawing groove 101, the first end of the punch 30 abuts against the main body 10, which is equivalent to the stroke of the punch 30 to fill the space of the drawer plate 20. In this way, after the punch 30 moves according to the stroke, the second end no longer punches holes, thereby forming a sheet material 80 without holes. In this way, the present application is suitable for the processing of hole-shaped and hole-free sheets 80 by quickly adjusting the device structure, and can be mass-produced with high processing efficiency. On the other hand, it can ensure processing quality and reduce processing costs.

[0037] Please refer to Figure 2In some embodiments, the pulling groove 101 and the mounting groove 102 are opened on different sides of the main body 10, so that the thickness direction of the drawing plate 20 is consistent with the moving direction of the punch 30. As shown in the figure, the pulling groove 101 is opened on the side of the main body 10, and the mounting groove 102 is opened at the bottom of the main body 10. In this way, the drawing plate 20 is pulled from the side of the main body 10, and the punch 30 moves up and down from the bottom of the main body 10 along the line connecting the first end and the second end, that is, moves along the axial direction of the punch 30 in the figure. When the punch 30 moves, the first end can enter the pulling groove 101 and abut against the inner wall of the main body 10 at the pulling groove 101, which is equivalent to reducing the stroke of the punch 30; in an optional embodiment, the opening direction of the pulling groove 101 is perpendicular to the opening direction of the mounting groove 102, so that the moving direction of the drawing plate 20 is perpendicular to the direction of the line connecting the first end and the second end. In some embodiments, the mounting groove 102 matches the punch 30, and the size of the first end is larger than the size of other positions of the mounting groove 102, that is, the first end of the punch 30 is larger, such as the punch 30 adopts an axis structure, and the first end is convexly arranged on the outer circumference to form a ring structure, so that the first end forms a step on the punch 30, and the mounting groove 102 matches the shape and size of the punch 30, and the mounting groove 102 is provided with a step groove at the position in contact with the drawing groove 101, and the first end is stuck at the step groove, so that the punch 30 is limited in the main body 10 through the mounting groove 102 and can move within the thickness range of the drawing groove 101. In some embodiments, the width of the draw plate 20 inserted into the drawing groove 101 is larger than the outer diameter at the first end, so that the draw plate 20 can cover the first end in the main body 10, and when the punch 30 moves along the moving direction of the first end and the second end, it can enter the drawing groove 101 completely, and the movement of the punch 30 is blocked.

As shown in the figure, the insert 40 is placed in the stroke direction of the punch 30, the insert 40 is in the shape of a plate or a block, and there is a gap between the insert 40 and the main body 10, and the punch 30 occupies the gap position. When in use, the sheet material 80 is laid flat on the top of the insert 40, and the position of the hole or groove to be punched is aligned with the through hole of the insert 40, and the second end of the punch 30 is aligned with the through hole position of the insert 40, so that the punch 30 can enter the through hole when moving according to the stroke. In some embodiments, the thickness S of the draw plate 20 is greater than the axial stroke e of the punch 30 relative to the insert 40, the axial stroke e is the stroke of the punch 30 along the first end and the second end, e is greater than the thickness of the sheet 80, the axial stroke e is equal to the thickness of the sheet 80 plus the depth of the second end inserted into the insert 40, and the thickness S of the draw plate 20 is the height that the punch 30 can adjust in the draw groove 101 when it is active; by setting the above thickness S and axial stroke e, when not drawn When the drawer plate 20 is pulled out, the punch 30 can cooperate with the main body 10 and the drawer plate 20 as a whole to punch holes in the sheet material 80 placed on the insert 40; after the drawer plate 20 is pulled out, the punch 30 moves within its stroke, and the second end abuts against the sheet material 80 placed on the insert 40, driving the punch 30 to move upward relative to the main body 10 within its stroke, until the first end abuts against the inner wall of the main body 10 of the drawer groove 101. At this time, the punch 30 does not punch holes in the sheet material 80, and blanking can be performed without.

[0039] Please refer to Figure 3 In some embodiments, the main body 10 includes a mold body 11 and a mounting seat 12, that is, the main body 10 is a detachable structure, the mold body 11 is used to connect to the output end of the punching machine, such as the top of the mold body 11 is fixedly connected to the output end of the press, which is a conventional setting, and the mounting seat 12 is fixed to the mold body 11, the top of the mounting seat 12 is flat and fits with the bottom of the mold body 11, the mounting seat 12 is provided with a pull-out groove 101 and a mounting groove 102, the pull-out groove 101 is opened at the top of the mounting seat 12, and the notch is located on the side of the mounting seat 12, the mounting groove 102 is opened in the middle of the mounting seat 12, the upper end is connected to the pull-out groove 101, and the lower end is the notch of the mounting groove 102, the mounting seat 12 is fixed to the mold body 11, and a variety of fixing methods can be adopted.

[0040] Please refer to Figure 3In some embodiments, the adaption processing mold further includes a fixing member 70. The fixing member 70 can be a bolt, a screw or other parts that are convenient for fixing and connecting. When the draw plate 20 is completely inserted into the draw groove 101, a connection hole is provided in the part exposed to the draw groove 101, and the mold body 11 is also provided with a connection hole at a corresponding position. The fixing member 70 matches the two connection holes. The fixing member 70 is used to connect the draw plate 20 with the main body 10 when the draw plate 20 is completely inserted into the draw groove 101. In this way, the draw plate 20 will not move, and the connection stability between the draw plate 20 and the mold body 11 is strengthened. In some embodiments, in order to facilitate the extraction of the draw plate 20, a protrusion can be provided at the exposed part of the draw plate 20, such as a convex edge is provided at the bottom of the edge of the draw plate 20 to form a bend shape, so that it is convenient to hold the draw plate 20 for operation.

[0041] In some embodiments, the adaptation processing mold further includes a positioning member 50, the mounting seat 12 is provided with a positioning hole, the positioning member 50 is provided in the positioning hole, the positioning hole passes through the top and bottom surfaces of the mounting seat 12, and the corresponding position of the mold body 11 is also provided with a hole, the positioning member 50 is a pin, a pin shaft or other parts convenient for positioning, after the mounting seat 12 and the mold body 11 are positioned correspondingly, the positioning member 50 is inserted to facilitate the positioning of the mounting seat 12 and the mold body 11.

[0042] Please refer to Figure 4 and Figure 5 In addition to being applied to sheet materials 80 with or without hole patterns, the present application can also be applied to sheet materials 80 with notches, and the above-mentioned adaption processing mold can be used. The above-mentioned mounting seat 12 is formed in a cylindrical shape, while in this embodiment, the shape of the mounting seat 12 is a cube. The shape of the mounting seat 12 is changed, and other regular shapes can also be used, while other components such as the mold body 11, the draw plate 20, the insert 40, etc. are the same as the above-mentioned adaption processing mold. The biggest difference of this embodiment is that the sheet materials 80 to be processed are different. If a sheet material 80 with a notch on the edge needs to be processed, the sheet material 80 can be placed on the insert 40, so that the edge of the sheet material 80 to be processed is aligned with the second end of the punch 30. The punch 30 punches out a notch on the edge of the sheet material 80 under the drive of the press and the main body 10. When the notch is not needed, the draw plate 20 is pulled out, and the punch 30 no longer punches the sheet material 80 under the same stroke.
