Description

Technical Field

[0001] This utility model relates to the field of welding ring rounding and flattening technology, specifically to a welding ring processing mold. Background Technology

[0002] In automotive parts, welding rings are a commonly used component. The manufacturing process involves shaping a steel metal ring into a circle, welding the interface, and then using a mold to complete the rounding operation.

[0003] Traditional rounding molds use multi-lobed inner circular shaping blocks to apply pressure outwards to round the ring. This rounding tooling cannot achieve a rounded result in one pass; it requires multiple manual interventions, rotations, and extrusions within the mold cavity to meet the roundness requirements. Furthermore, traditional rounding molds lack the function of flattening the end face of the welded ring. The punch is a consumable part; replacing the punch in traditional rounding molds requires disassembling the entire mold set, which is time-consuming and labor-intensive, thus reducing the forming efficiency of the welded ring. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to solve the problem that the processing of welded rings cannot meet the requirement of simultaneous inner and outer circular and flattening in one operation.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A welding ring processing mold includes an upper mold mechanism and a lower mold mechanism. A flat plate is provided between the upper mold mechanism and the lower mold mechanism. The flat plate and the upper mold mechanism can move toward the lower mold mechanism, and the flat plate can contact the lower mold mechanism.

[0007] The upper mold mechanism includes a detachable punch mechanism facing the lower mold mechanism. The punch mechanism can extend through the flat plate into the lower mold forming groove of the lower mold mechanism. Movable outer circular guard blocks are provided on both sides of the lower mold forming groove. The upper mold mechanism is provided with a cutting tool that can push the outer circular guard blocks to move.

[0008] This application features a detachable punch in the upper mold for rounding the inside of the welding ring; and a movable outer circle guard block in the lower mold for rounding the outside of the welding ring. This application employs upper and lower rounding components to achieve simultaneous rounding of the inside and outside of the ring in one operation, ensuring the accuracy of the rounding. The flat plate descends and presses down onto the end face of the welding ring, enabling the end face of the welding ring to be leveled, thus completing a single operation of simultaneous rounding and flattening of the inside and outside of the ring.

[0009] As a further embodiment of this utility model: both sets of outer circular protective blocks move toward the center of the lower mold forming groove, and can be spliced ​​into a circular structure.

[0010] As a further embodiment of this utility model: the upper mold mechanism includes an upper mold base, an upper pad is provided at the bottom of the upper mold base, a punch mechanism is provided at the bottom of the upper pad, and an upper top post and a cutting tool are also provided at the bottom of the upper pad and outside the punch mechanism.

[0011] As a further embodiment of this utility model: the punch mechanism includes a punch base connected to the upper pad, and a punch is detachably installed on the bottom of the punch base.

[0012] As a further embodiment of this utility model: the flat plate is located below the lower mold mechanism, and a through hole is provided on it for the passage of the punch mechanism and the inserter.

[0013] As a further embodiment of this utility model: a positioning rod and an equalizing sleeve are installed on the lower mold mechanism and located outside the lower mold forming groove, and both the positioning rod and the equalizing sleeve are slidably connected to the whole plate.

[0014] As a further embodiment of this utility model, a nitrogen spring is also provided between the lower mold mechanism and the flat plate.

[0015] As a further embodiment of this utility model: the lower mold mechanism includes a lower mold base, a lower pad is provided on the top of the lower mold base, a concave template is provided above the lower pad, and the lower mold forming groove is provided on the concave template and corresponds to the punch mechanism.

[0016] As a further embodiment of this utility model: the outer circular guard block is connected to a slider on one side of the mold forming groove on the back side, and the slider is slidably connected in the concave template.

[0017] As a further embodiment of this utility model: the bottom of the inserter is inclined to the side facing the slider, and the inserter can push the slider to move towards the lower mold forming groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] First, this application provides a detachable punch in the upper mold for rounding the inside of the welding ring; and a movable outer circle guard block in the lower mold for rounding the outside of the welding ring. This application uses upper and lower rounding components to achieve synchronous rounding of the inside and outside of the ring in one operation, ensuring the rounding accuracy. Furthermore, the flat plate moves down and presses against the end face of the welding ring, which can perform a leveling operation on the end face of the welding ring, completing a synchronous rounding and flattening operation.

[0020] Secondly, the flat plate is used to simultaneously complete the leveling operation of the ring, and the punch of the mold is fastened to the punch base with special bolts. When the punch wears, only the special bolts need to be removed, which makes it easier to replace and maintain the punch regularly. This simplifies the mold structure, while simultaneously completing the functions of synchronous internal and external rounding and flattening, and also facilitates the regular replacement and maintenance of the punch.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Reference Figure 1 A welding ring processing mold includes an upper mold mechanism, a forming plate 5, and a lower mold mechanism, wherein the forming plate 5 is located between the upper mold mechanism and the lower mold mechanism, and both the forming plate 5 and the upper mold mechanism can move toward the lower mold mechanism to perform subsequent synchronous rounding and flattening functions.

[0029] Reference Figure 1 , Figure 2 and Figure 3The upper mold mechanism includes an upper mold base 1, an upper pad 2, an upper fixed plate 3, a cutter 4, a flat plate 5, a punch base 6, an upper ejector pin 7, and a punch 8. Specifically, the upper mold base 1 has an upper pad 2 at its bottom, and the punch base 6 is located at the middle of the bottom of the upper pad 2. The bottom of the punch base 6 is detachably connected to the punch 8 by bolts. The upper ejector pin 7 and the cutter 4 are also located at the bottom of the upper pad 2 and on the outside of the punch base 6. The length of the cutter 4 is longer than the length of the upper ejector pin 7. The upper fixed plate 3 is also located at the bottom of the upper pad 2, and the cutter 4, the punch base 6, and the upper ejector pin 7 all pass through the upper fixed plate 3 and are connected to the upper pad 2.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The plate 5 is located directly below the upper fixed plate 3. A through hole for the punch 8 is reserved in the middle of the plate 5, and through holes for the insert 4 are also provided on both sides. Therefore, both the insert 4 and the punch 8 can move towards the lower mold mechanism through the corresponding through holes.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The lower mold mechanism includes a lower mold base 15, with pads 16 installed on both sides of the bottom of the lower mold base 15, and a lower pad plate 14 detachably installed on the top of the lower mold base 15. A concave template 12 is installed on the top of the lower pad plate 14, and the concave template 12 is located directly below the flat plate 5. A lower mold forming groove is provided in the middle of the concave template 12, and movable outer circular guard blocks 11 are provided on both sides of the top of the lower mold forming groove. Slider blocks 13 are respectively installed at the ends of the two sets of outer circular guard blocks 11, and the sliders 13 can slide and connect inside the concave template 12.

[0032] The top side of the slider 13 is set to be inclined, and the bottom side of the insert 4 facing the slider 13 is also set to be inclined. When the slider 13 moves down, its bottom can push the corresponding slider 13 to move towards the direction of the lower mold forming groove, and finally the two sets of outer circle guard blocks 11 can be spliced ​​into a circular structure, and the bottom of the insert 4 eventually moves to the side of the slider 13 and is in close contact with the slider 13.

[0033] Positioning rods and leveling sleeves 9 are detachably installed on both sides of the top of the concave template 12. The tops of the positioning rods and leveling sleeves 9 are slidably connected to the flat plate 5, meaning that the positioning rods and leveling sleeves 9 do not affect the downward movement of the flat plate 5. Correspondingly, positioning holes (such as those corresponding to the positioning rods and leveling sleeves 9) are provided on the upper fixed plate 3. Figure 2 As shown in the figure, this ensures the accuracy of subsequent welding ring forming.

[0034] A nitrogen spring 10 is also provided between the concave template 12 and the flat plate 5. The nitrogen spring 10 can be used to support the flat plate 5 and does not affect the subsequent downward movement of the flat plate 5.

[0035] The specific operating principle of this application is as follows:

[0036] The welding ring to be rounded and flattened is placed on the concave template 12 in the middle of the outer circular guard blocks 11 of the left and right semicircles; the two inserts 4 of the mold press down, applying pressure to the left and right sliders 13, which move towards the middle, closing the outer circular guard blocks 11 of the left and right semicircles. A punch 8 of a fixed size is set in the middle of the punch base. The punch 8 moves down, pressing the welding ring. Then the upper ejector 7 moves down to press the flat plate 5, driving the flat plate 5 down to press against the end face of the welding ring, performing a flattening operation on the end face of the welding ring, completing one rounding and flattening operation of the inner and outer sides.

[0037] This invention employs upper and lower rounding components to achieve simultaneous rounding of the inner and outer rings in a single operation, ensuring rounding accuracy. The leveling plate 5 simultaneously completes the leveling operation of the ring, and the die punch 8 is securely connected to the die punch base 6 with special bolts. When the die punch 8 wears, only the special bolts need to be removed, making regular replacement and maintenance of the die punch 8 more convenient. This design simplifies the die structure while simultaneously achieving simultaneous inner and outer rounding and leveling, and also facilitates regular replacement and maintenance of the die punch 8.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
