Description

Technical Field

[0001] The utility model relates to the technical field of processing machinery, in particular to a punching die tool. Background Art

[0002] In machining, it is often necessary to process through holes on the workpiece. For example, there are two waist-shaped holes on one side of the connecting plate (angle steel) of the drag chain bracket that need to be processed, and the opening and size of the two waist-shaped holes are not unique.

[0003] The current conventional production method for connecting plates for drag chain brackets is as follows: 1. Mark the surface of the connecting plate workpiece, marking the opening dimensions of the two waist-shaped holes, the base hole position lines, and the outer contour lines according to the drawing requirements. 2. Transfer the workpiece to the drilling machine processing area. 3. The worker places the workpiece on the drilling machine table, adjusts the reference and workpiece position according to the marked hole position lines, secures the workpiece, and then drills the bottom holes at the base of the waist-shaped holes. 4. Transfer the workpiece to the milling machine processing area. 5. The worker places the workpiece on the milling machine table, adjusts the reference and workpiece position according to the marked lines, secures the workpiece, and then mills the two waist-shaped holes. This process requires multiple operations such as transfer, clamping, and tool setting, which is time-consuming and lengthy. This conventional process requires high worker skills, is generally difficult to adjust quickly, and has a long processing cycle, making it unsuitable for high-volume, short-run production. Furthermore, the frequent replacement of references easily leads to cumulative errors and unstable interchangeability. Utility Model Content

[0041] Figure 1 This is a schematic diagram of the structure of the die tooling 100 provided in this embodiment installed on the shearing machine 200. Figure 2 for Figure 1 A top view of the structure shown, Figure 3 for Figure 1 The left view of the structure shown. Please refer to Figure 1-Figure 3The present embodiment provides a die tool 100, which includes an upper die 111, a lower die 112, a work platform 120, a first positioning member 130 and a second positioning member 140. The upper die 111 and the lower die 112 are respectively used to be installed on the shearing machine 200 in an upper and lower corresponding manner, and the upper die 111 is also used to press toward the die under the action of the shearing machine 200, thereby punching a through hole in the workpiece 300 located between the upper and lower dies 112. The work platform 120 is located between the upper die 111 and the lower die 112, and is used to support the workpiece 300. The work platform 120 has a notch 125 and a plurality of mounting holes 126. The notch 125 is used to allow a punching path from the upper die 111 to the lower die 112, so that the movement of the upper die 111 to the lower die 112 punches a through hole in the portion of the workpiece 300 located at the notch 125. The first positioning member 130 and the second positioning member 140 are detachably mounted in the mounting hole 126. The first positioning member 130 is used to limit the workpiece 300 so that the workpiece 300 is at the first station, thereby realizing die processing at the first station. The second positioning member 140 is used to limit the workpiece 300 at the second station, thereby realizing die processing at the second station. The use of die processing to replace the milling processing method in the existing technology makes processing less difficult and requires less technical skills from workers. In addition, the first positioning member 130 and the second positioning member 140 are used to position the first station and the second station respectively. During the same batch of processing, there is no need to frequently adjust the reference, which helps to ensure the stability of the processing position and reduce processing errors. In addition, the positions of the first positioning member 130 and the second positioning member 140 are adjustable, and the positions of the first positioning member 130 and the second positioning member 140 can be adjusted according to needs.

[0042] In this embodiment, the workpiece 300 is an angle steel used for processing the connecting plate of the drag chain bracket. It can be understood that in some other embodiments, the workpiece 300 can also be other similar components.

[0043] The structure of the die tool 100 provided in this embodiment is further described below:

[0044] Please continue to refer to Figure 1-Figure 3 In this embodiment, the upper die 111 is installed on the die part on the slider of the shearing machine 200, and the lower die 112 is installed on the base of the shearing machine 200, and the upper die 111 and the lower die 112 are directly opposite each other. During processing, the workpiece 300 is placed between the upper die 111 and the lower die 112, and the upper die 111 is driven downward by the shearing machine 200 to cooperate with the lower die 112 to perform the stamping operation, and the material is removed after punching by the lower die 112 to ensure the continuity and efficiency of punching.

[0045] Optionally, there are multiple upper dies 111 and multiple lower dies 112 , and the multiple upper dies 111 and the multiple lower dies 112 are matched one by one. Figure 4 Shows a structure of an upper mold 111, Figure 5 Shown Figure 4 The structural diagram of the A direction is as follows: Figure 4 and Figure 5 As shown, the upper die 111 has a raised portion 113 having the same size and shape as the through hole required to be punched on the workpiece 300. The raised portion 113 acts downward on the workpiece 300 to punch out a through hole. In this embodiment, the through hole is a waist-shaped hole. Figure 6 The structure of a lower die 112 is shown. The lower die 112 has a recessed portion 114 with substantially the same structural dimensions as the raised portion 113 of the upper die 111. Both the upper die 111 and the lower die 112 are detachably connected to the shearing machine 200. When a waist-shaped hole is to be punched, the corresponding upper die 111 and the matching lower die 112 are selected according to the size of the waist-shaped hole, and the upper die 111 and the lower die 112 are installed in the shearing machine 200. This allows the processing of through holes of different sizes and types by replacing the upper die 111 and the lower die 112.

[0046] Figure 7 This is a structural diagram of the working platform 120 in the die tooling 100 provided in this embodiment. Figure 1-Figure 7 In this embodiment, the work platform 120 is disposed between the upper die 111 and the lower die 112, and supports the workpiece 300. A notch 125 is provided on the work platform 120. When the work platform 120 is placed between the upper die 111 and the lower die 112, the notch 125 is located directly below the upper die 111. This notch 125 avoids the blanking path of the upper die 111 toward the lower die 112, allowing the upper die 111 to smoothly blank the workpiece 300.

[0047] Specifically, the work platform 120 includes a top plate 121 , which is a generally square plate-shaped member having a length direction X and a width direction Y. A notch 125 is formed on the top plate 121 , and the notch 125 passes through the top plate 121 in the vertical direction and forms an opening at an edge of one side of the top plate 121 in the width direction.

[0048] Furthermore, the work platform 120 includes a support plate 124. The upper end of the support plate 124 is fixedly connected to the top plate 121, and the lower end of the support plate 124 is used to contact the shearing machine 200 to support the work platform 120. Specifically, the support plate 124 is a plate-shaped member, which is arranged perpendicular to the bottom surface of the top plate 121, thereby forming the work platform 120 with a T-shaped cross-section. The support plate 124 is generally trapezoidal in shape, with its lower base fixedly connected to the top plate 121 and its upper base facing downward to contact the shearing machine 200.

[0049] The top plate 121 includes a first plate portion 122 located on one side of the support plate 124 and a second plate portion 123 located on the other side of the support plate 124. The notch 125 is provided in the first plate portion 122. Specifically, the support plate 124 extends along the length of the top plate 121, thereby dividing the top plate 121 into the first plate portion 122 and the second plate portion 123, which are distributed along the width direction, with the position of the support plate 124 as the dividing line. The notch 125 is provided in the first plate portion 122, and the notch 125 is open to the side away from the second plate portion 123.

[0050] Figure 8 This is a structural diagram of the working platform 120 in the die tooling 100 provided in this embodiment from another perspective. Figures 1-8 Furthermore, the die fixture 100 also includes a support block 151, which is fixedly connected to the shearing machine 200, and the upper end of the support block 151 is also used to support the bottom of the second plate portion 123. Specifically, the lower end of the support block 151 has a plug-in slot, which is plugged into the shearing machine 200 and fixedly connected to the shearing machine 200 by bolts. The support block 151 is located on the lower side of the second plate portion 123, thereby supporting the work platform 120. During installation, the support plate 124 of the work platform 120 is placed between the support block 151 and the lower die 112. The support block 151 is supported below the second plate portion 123. Through the cooperation between the support block 151 and the support plate 124, the work platform 120 is stably supported on the shearing machine 200.

[0051] The mounting holes 126 on the work platform 120 include a plurality of first mounting holes 127 and a plurality of second mounting holes 128, which are distributed along the length. The first mounting holes 127 are located on one side of the notch 125 along the width direction and are used to mount the first positioning member 130. The second mounting holes 128 are located on one side of the notch 125 along the length direction and are used to mount the second positioning member 140.

[0052] Specifically, the mounting holes 126 are formed on the top plate 121, with the first mounting hole 127 located on the first plate portion 122 and the second mounting hole 128 located on the second plate portion 123. Thus, in the width direction, the plurality of first mounting holes 127 are all located on one side of the notch 125. Optionally, the plurality of first mounting holes 127 form two rows distributed along the width direction, thereby allowing for more flexible selection of mounting positions when installing the first positioning member 130; and the plurality of second mounting holes 128 form two rows distributed along the width direction, thereby allowing for more flexible selection of mounting positions when installing the second positioning member 140.

[0053] Optionally, the first mounting hole 127 and the second mounting hole 128 are both threaded holes, and the first positioning member 130 and the second positioning member 140 are both threadedly installed at the mounting hole 126 .

[0054] Figure 9 This is a schematic structural diagram of the positioning seat 131 in the die tooling 100 provided in this embodiment. Figure 10 This is a schematic diagram of the structure of the positioning rod 133 in the die tooling 100 provided in this embodiment. Figures 1-10 In this embodiment, the first positioning member 130 includes a positioning seat 131 and a positioning rod 133 that is plugged into the positioning seat 131. The positioning seat 131 is detachably installed in the first mounting hole 127. The positioning rod 133 is used to contact one end of the workpiece 300 along the length direction, thereby limiting the workpiece 300.

[0055] Specifically, the positioning seat 131 is detachably fixed in the first mounting hole 127 by fasteners such as bolts, and the positioning seat 131 has an insertion hole 132, the positioning rod 133 is inserted in the insertion hole 132, and the end of the positioning rod 133 forms a positioning portion 136. When the positioning portion 136 extends out of the plug hole 132 and is located above the first plate portion 122, the positioning portion 136 blocks one side of the workpiece 300 along the length direction, thereby limiting the position of the workpiece 300 in the length direction. The limited position is the first workstation, and the positioning rod 133 is in a positioning state at this time; when the positioning portion 136 retracts into the plug hole 132, the blocking effect of the positioning portion 136 on the workpiece 300 disappears. At this time, the positioning rod 133 is in an unlocked state, and the workpiece 300 can pass the position of the first positioning member 130 until it is blocked by the second positioning member 140, thereby being limited to the second workstation. In other words, in this embodiment, the first workstation and the second workstation are located at different positions in the length direction of the working platform 120.

[0056] It should be noted that, in this embodiment, the workpiece 300 only needs to be punched and punched at the first and second stations. Accordingly, only one first positioning member 130 and one second positioning member 140 are provided. It can be understood that in some other embodiments, if the workpiece 300 needs to be punched and punched at three positions, the first positioning member 130 can be set to two, and the two first positioning members 130 are installed in different first mounting holes 127, so that the workpiece 300 can be limited at different positions.

[0057] Furthermore, the positioning rod 133 includes a first rod segment 134 and a second rod segment 135. One end of the first rod segment 134 is fixedly connected to the second rod segment 135, and the extension directions of the first rod segment 134 and the second rod segment 135 form an angle. The first rod segment 134 is used to plug into the insertion hole 132. The end of the first rod segment 134 away from the second rod segment 135 serves as a positioning portion 136. In this way, the second rod segment 135 is always located outside the insertion hole 132. The operator can switch between the positioning state and the unlocked state by operating the second rod segment 135. At the same time, when the positioning rod 133 is in the positioning state, the second rod segment 135 can also interfere with the positioning seat 131 to limit the position of the positioning rod 133.

[0058] The second positioning member 140 includes a positioning plate 141 and a fastener 142. The positioning plate 141 is removably mounted in the second mounting hole 128 via the fastener 142. The positioning member is used to abut one end of the workpiece 300 along its length to limit the position of the workpiece 300. Specifically, the fastener 142 may be a bolt or other structure. The positioning plate 141 is a plate-shaped member having a hole therein for the fastener 142 to pass through. Optionally, the hole in the positioning plate 141 is a waist-shaped hole extending along its length, thereby improving the positioning accuracy of the positioning plate 141 and ensuring the accuracy of the punching position.

[0059] Furthermore, second mounting holes 128 are provided on both sides of the notch 125 along the length direction, so that the second positioning member 140 can be installed on both sides of the notch 125 as needed, thereby facilitating the processing of the workpiece 300 .

[0060] Please refer again Figure 2 In this embodiment, the die fixture 100 also includes a third positioning member 152 installed in the first mounting hole 127. The third positioning member 152 interferes with one side of the workpiece 300 in the width direction, so that the third positioning member 152 can prevent the workpiece 300 from being offset in the width direction of the working platform 120.

[0061] The die tooling 100 provided by the present invention is first installed on the shearing machine 200 when in use. Then, according to the position of the waist-shaped hole to be processed on the workpiece 300 to be processed, the positions of the first positioning member 130 and the second positioning member 140 are determined, and the first positioning member 130 is placed in a positioning state. Then, the workpiece 300 is placed on the working platform 120 and positioned to a position where the workpiece 300 conflicts with the first positioning member 130. At this time, the workpiece 300 is in the first position (such as Figure 2 As shown), the shearing machine 200 is then operated to press the upper die 111 downward to perform blanking to achieve the processing of the first waist-shaped hole; after the processing is completed, the first positioning member 130 is switched to the unlocked state, and the workpiece 300 is moved to a position where it contacts the second positioning member 140. At this time, the workpiece 300 is in the second position (as shown). Figure 11As shown), the shearing machine 200 is then operated to press down the upper die 111 for blanking to realize the processing of the second waist-shaped hole. At this time, the processing of the workpiece 300 is completed. After the workpiece 300 is removed, the above process can be repeated to realize the processing of another workpiece 300. The waist-shaped holes of the same batch of workpieces 300 processed and formed are in the same position. There is no need to repeatedly adjust the reference during the processing, which effectively ensures the interchangeability of the workpieces 300. When it is necessary to process other workpieces 300, the positions of the first positioning member 130 and the second positioning member 140 can be adjusted. The punching die fixture 100 has high processing efficiency, greatly shortens the processing cycle, and has low operating difficulty, which effectively reduces labor costs.

[0062] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with the technology in this field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
