[0036] This utility model embodiment provides a universal heat insulation cover stamping die for stamping side holes on a workpiece, including:
[0037] The mold base assembly 1 includes a first mold base 11, a second mold base 12, and a support member 13. The first mold base 11 and the second mold base 12 are spaced apart along a first direction X. One end of the support member 13 is fixedly connected to the first mold base 11, and the other end is fixedly connected to the second mold base 12. The first mold base 11 is provided with a first fixing member 14 on the side near the second mold base 12, and the second mold base 12 is provided with a second fixing member 15 on the side near the first mold base 11. The second fixing member 15 is provided with a first through hole 15a, which extends along a second direction Y and penetrates the second fixing member 15.
[0038] Punch 2 is fixedly connected to the first fixing member 14 and is used to punch side holes toward the workpiece in the first direction X;
[0039] A die insert 3 is fixedly connected to one side of the second fixing member 15. The outer side of the die insert 3 is provided with a stamping groove 3a, which corresponds to the position of the punch 2. The die insert 3 is provided with a second through hole 3b, which extends along the second direction Y, penetrates the die insert 3, and communicates with the first through hole 15a.
[0040] A plurality of quick-change components 4 are provided, the quick-change components 4 extending along the second direction Y and disposed in the first through hole 15a and the second through hole 3b. The quick-change components 4 are provided with protrusions 41, the protrusions 41 protruding toward the third direction Z, the third direction Z being collinear with or intersecting the first direction X, and the protrusions 41 being used to be disposed in the large hole of the workpiece.
[0041] In a specific embodiment, such as Figure 5 As shown, the first mold base 11 and the second mold base 12 are spaced apart in the vertical direction. The first mold base 11 is provided with the first fixing member 14 on its lower side, and the punch 2 is fixedly connected to the lower side of the first fixing member 14. The second mold base 12 is provided with the second fixing member 15 on its upper side, and the die insert 3 is provided on the left side of the second fixing member 15. The die insert 3 is provided with the stamping groove 3a above the die insert 3, and the stamping groove 3a corresponds to the position of the punch 2. Thus, when the punch 2 performs stamping work downwards towards the workpiece, the stamped parts can flow out from the stamping groove 3a.
[0042] like Figure 5 , Figure 6 , Figure 7 As shown, the second through hole 3b on the die insert 3 communicates with the first through hole 15a on the second fixing member 15 and extends in the left-right direction. Before operation, determine the type of workpiece to be processed, select a suitable quick-change assembly 4, and place the quick-change assembly 4 in the second through hole 3b and the first through hole 15a. During operation, place the workpiece on the die insert 3, so that the protrusion 41 on the quick-change assembly 4 is inserted into the large hole B in the middle of the workpiece, open the punch 2 on the upper first fixing member 14, the punch 2 presses downward and forms a side hole on the workpiece, and the stamped part falls off from the stamping groove 3a on the die insert 3.
[0043] It should be noted that in this application, the third direction Z where the protrusion 41 is located is not limited in different quick-change components 4. This application includes several quick-change components 4. When different quick-change components 4 are replaced, the orientation of the protrusion 41 on the quick-change block 43 is different from the punching angle of the punch 2, thereby enabling the processing of different types of workpieces.
[0044] In a specific embodiment, such as Figure 7and Figure 8 As shown, the upper side of the quick-change component 4 is provided with the protrusion 41, that is, the third direction Z is collinear with the first direction X, as shown. Figure 5 and Figure 6 As shown, during installation, the large hole B of the workpiece is aligned with the protrusion 41, and the punch 2 on the first fixing member 14 punches the side hole A1 of the workpiece downwards. At this time, the side hole A1 on the processed workpiece is directly above the large hole B, thus obtaining the first type of workpiece (such as...). Figure 1 and Figure 2 (as shown)
[0045] In yet another specific embodiment, such as Figure 9 As shown, the quick-change assembly 4 has a protrusion 41 located slightly to the right of its upper side, where the third direction Z intersects the first direction X and the third direction Z faces to the right front. During installation, the large hole B of the workpiece is aligned with the protrusion 41, and the punch 2 on the first fixing member 14 punches the side hole A1 of the workpiece downwards. At this time, the side hole A2 on the processed workpiece is located to the left front of the large hole B, thus obtaining a second type of workpiece (such as...). Figure 3 (as shown)
[0046] In another specific embodiment, such as Figure 10 As shown, the quick-change assembly 4 has a protrusion 41 located slightly to the left of its upper side, where the third direction Z intersects the first direction X and faces to the left front. During installation, the large hole B of the workpiece is aligned with the protrusion 41, and the punch 2 on the first fixing member 14 punches the side hole A3 of the workpiece downwards. At this time, the side hole A3 on the processed workpiece is located to the right front of the large hole B, thus obtaining a third type of workpiece (such as...). Figure 4 (As shown).
[0047] During processing, different types of workpieces can be processed simply by quickly changing the quick-change component 4 of different specifications, reducing the mold manufacturing cycle and cost. The process is convenient to switch between components, highly operable, and greatly improves processing efficiency.
[0048] The concave mold insert 3 and the second fixing member 15 can be integrally formed or separately set and then fixedly connected by welding or other means.
[0049] Furthermore, the second fixing member 15 is also provided with a stamping through hole 15b, which is connected to the stamping groove 3a. The stamping through hole 15b is inclined towards the center of the second fixing member 15 from the side close to the die insert 3 to the side away from the die insert 3.
[0050] In a specific embodiment, such as Figure 6As shown, the second fixing member 15 is provided with the stamping through hole 15b above it. The stamping through hole 15b extends downward, so that the stamped parts enter the stamping through hole 15b from the stamping groove 3a on the die insert 3 and fall out of the second fixing member 15. This structure is simple, reasonably designed, and conducive to collecting the stamped parts.
[0051] Furthermore, the quick-change component 4 includes:
[0052] A quick-change plate 42 is provided with a mounting through hole, which penetrates the quick-change plate 42 along the second direction Y. The quick-change plate 42 is disposed in the first through hole 15a and / or the second through hole 3b.
[0053] The quick-change block 43 extends along the second direction Y and is disposed in the mounting through hole. The quick-change block 43 has the protrusion 41 on the side opposite to the concave mold insert 3.
[0054] In a specific embodiment, such as Figure 5 As shown, during installation, the quick-change plate 42 is first inserted into the second through hole 3b and the first through hole 15a, and then the quick-change block 43 is inserted into the mounting through hole of the quick-change plate 42. Since the quick-change block 43 has the protrusion 41 on its left side, when the workpiece is placed on the die insert 3, the protrusion 41 can protrude and be inserted into the large hole B, which plays the role of positioning and fixing the workpiece.
[0055] Furthermore, the cross-sectional area of the quick-change component 4 is smaller than the cross-sectional area of the first through hole 15a; and / or, the cross-sectional area of the quick-change component 4 is smaller than the cross-sectional area of the second through hole 3b.
[0056] In a specific embodiment, such as Figure 5 , Figure 6 , Figure 7 As shown, the cross-sectional area of the first through hole 15a is equal to the cross-sectional area of the second through hole 3b. Making the cross-sectional area of the quick-change component 4 smaller than the cross-sectional areas of the first through hole 15a and the second through hole 3b helps to reduce the weight of the aftertreatment diesel engine heat shield mold and achieve lightweight design.
[0057] Furthermore, the inner wall of the first through hole 15a and / or the second through hole 3b is provided with a positioning step 15c.
[0058] The quick-change plate 42 has a boss 4a on its outer side that matches the positioning step 15c.
[0059] The positioning step 15c facilitates the rapid installation of the quick-change assembly 4, thereby improving processing efficiency. The number of positioning steps 15c is not limited. In one specific embodiment, a positioning step 15c is provided on the inner wall of the first through hole 15a, and a boss 4a is provided on the outer side of the quick-change plate 42. The boss 4a matches the position and shape of the positioning step 15c. In another specific embodiment, such as... Figure 6 As shown, the inner wall of the first through hole 15a is provided with a plurality of positioning steps 15c, and the outer side of the quick-change assembly plate 42 is provided with a plurality of bosses 4a, any boss 4a can correspond to and match a positioning step 15c.
[0060] Furthermore, the second fixing member 15 is also provided with a positioning pin 151, the line connecting the positioning pin 151 and the center of the second fixing member 15 intersects with the first direction X.
[0061] The line connecting the center of the positioning pin 151 and the center of the second fixing member 15 intersects the first direction X. This angle is not limited and can be adjusted according to actual needs. In a specific embodiment, such as... Figure 5 As shown, four equally spaced side holes need to be machined on the side of the workpiece. At this time, the angle between the line connecting the center of the positioning pin 151 and the center of the second fixing member 15 and the first direction X is set to 90°. During processing, the first side hole is punched on the side of the workpiece first, the workpiece is rotated and the positioning pin 151 is inserted into the side hole, and the second side hole is punched on the workpiece. Then the angle between the first side hole and the second side hole is 90°. Continue to rotate the workpiece and continue to punch, so that four equally spaced side holes can be punched continuously on the workpiece.
[0062] Furthermore, the support member 13 includes:
[0063] The first support member 131 has one end fixedly connected to one end of the first mold base 11 and the other end fixedly connected to one end of the second mold base 12.
[0064] The second support member 132 has one end fixedly connected to the other end of the first mold base 11 and the other end fixedly connected to the other end of the second mold base 12. For example... Figure 6 As shown, this structure is simple in design and highly stable, preventing shaking during stamping and improving machining accuracy.
[0065] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
