Description

Technical Field

[0001] This utility model relates to the field of cold stamping die technology, specifically to a shaping insert corner mechanism and a lower die for cold stamping. Background Technology

[0002] Currently, in the production process of cold stamping dies, if it is necessary to rotate the stamping direction to meet the punching or the flange springback compensation angle, the most common method is to use a rotating robot or a part dropping method to ensure that the part is rotated after being put in.

[0003] Using a rotary manipulator to achieve cornering would inevitably affect the production efficiency of automated manufacturing. Using a falling part method to achieve cornering would negatively impact production stability, especially if the part is too small, making it impossible to achieve cornering by falling itself.

[0004] Solving these problems is now a top priority. Utility Model Content

[0005] In view of this, the present invention provides a shaping insert corner mechanism and a cold stamping die lower mold.

[0006] The technical solution is as follows:

[0007] The first aspect of this application relates to a shaped insert corner mechanism, including a fixed mounting base, a lifting drive assembly and two guide mating assemblies both fixedly mounted on the fixed mounting base, a bottom mounting plate driven by the lifting drive assembly, and an insert mounting plate hinged to the side of the bottom mounting plate away from the fixed mounting base. The two guide mating assemblies are respectively located at both ends of the length direction of the bottom mounting plate. Limiting guide members are fixedly mounted at both ends of the length direction of the insert mounting plate. The limiting guide members are respectively provided with arc-shaped guide grooves adapted to the corresponding guide mating assemblies. Each guide mating assembly is slidably embedded in the corresponding arc-shaped guide groove.

[0008] When the bottom mounting plate moves closer to or further away from the fixed mounting base under the action of the lifting drive assembly, the insert mounting plate can rotate relative to the width direction of the bottom mounting plate.

[0009] The above-mentioned shaped insert corner mechanism is used, with the insert mounting plate hinged to the bottom mounting plate. At the same time, each guide fitting component is slidably fitted with each arc-shaped guide groove, so that the bottom mounting plate can be moved by the lifting drive component, and the insert mounting plate rotates while being lifted.

[0010] The second aspect of this application relates to a cold stamping die lower die, including a lower die base and at least one set of the above-mentioned shaping insert corner mechanism. The lower die base has recessed corner mechanism mounting grooves corresponding to each fixed mounting seat. Each fixed mounting seat is fixedly installed at the bottom of the corresponding corner mechanism mounting groove. Each insert mounting plate protrudes outward from the corresponding corner mechanism mounting groove and is fixedly installed with a shaping insert that rotates synchronously with it.

[0011] The lower die of the above cold stamping die not only has all the advantages of the above-mentioned shaping insert corner mechanism, but also enables the shaping insert to automatically rotate inside the die under the control of the shaping insert corner mechanism, thereby satisfying the function of changing the stamping direction. It will not affect the production efficiency of cold stamping die production, nor will it have a negative impact on stability. Attached Figure Description

[0022] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0023] Example 1:

[0024] like Figures 2-8 As shown, a shaped insert corner mechanism mainly includes a fixed mounting base 101, a lifting drive assembly 102, a bottom mounting plate 103, an insert mounting plate 105, two hinge assemblies 104, two guide engagement assemblies 106, and two limiting guide members 107.

[0025] In this embodiment, the lifting drive assembly 102 and the two guide mating assemblies 106 are both fixedly mounted on the fixed mounting base 101. The bottom mounting plate 103 is driven by the lifting drive assembly 102, that is, the bottom mounting plate 103 can be lifted and lowered under the drive of the lifting drive assembly 102. The insert mounting plate 105 is hinged to the side of the bottom mounting plate 103 away from the fixed mounting base 101 through two hinge assemblies 104, so that the insert mounting plate 105 can rotate relative to the width direction of the bottom mounting plate 103. At the same time, the two guide mating assemblies 106 are respectively located at both ends of the length direction of the bottom mounting plate 103. Limiting guide members 107 are fixedly installed at both ends of the length direction of the insert mounting plate 105. The limiting guide members 107 are respectively provided with arc-shaped guide grooves 107a that are adapted to the corresponding guide mating assemblies 106. The arc-shaped guide grooves 107a are all arc-shaped groove structures, and each guide mating assembly 106 is slidably embedded in the corresponding arc-shaped guide groove 107a.

[0026] Therefore, when the bottom mounting plate 103 moves closer to or further away from the fixed mounting base 101 under the drive of the lifting drive assembly 102, the insert mounting plate 105 can rotate relative to the width direction of the bottom mounting plate 103. In this embodiment, when the bottom mounting plate 103 is at the position closest to the fixed mounting base 101 under the drive of the lifting drive assembly 102, the insert mounting plate 105 is parallel to the bottom mounting plate 103; when the bottom mounting plate 103 moves away from the fixed mounting base 101 under the drive of the lifting drive assembly 102, the insert mounting plate 105 rotates relative to the width direction of the bottom mounting plate 103 while moving away from the fixed mounting base 101.

[0027] Please see Figure 5 Each guide assembly 106 includes a bearing housing 106a fixedly mounted on a fixed mounting base 101, a bearing mounting shaft 106b fixedly mounted on the bearing housing 106a, and a bearing 106c fitted onto the bearing mounting shaft 106b. The bearings 106c are respectively embedded in corresponding arc-shaped guide grooves 107a and can roll along the groove walls of the corresponding arc-shaped guide grooves 107a. Specifically, the inner ring of the bearing 106c is interference-fitted onto the bearing mounting shaft 106b, and the outer ring of the bearing 106c can roll along the groove walls of the corresponding arc-shaped guide grooves 107a, thereby ensuring smooth fit between the bearing 106c and the arc-shaped guide grooves 107a and preventing jamming.

[0028] Furthermore, the inner end of the bearing mounting shaft 106b is a screw structure with external threads, and the bearing housing 106a has a threaded hole that matches the inner end of the bearing mounting shaft 106b. The inner end of the bearing mounting shaft 106b is screwed into the threaded hole of the bearing housing 106a in a simple and reliable manner.

[0029] Meanwhile, each bearing mounting shaft 106b has a cotter pin insertion hole at its outer end. After the inner ring of the bearing 106c is interference-fitted onto the corresponding bearing mounting shaft 106b, the first cotter pin 106d is inserted into the corresponding cotter pin insertion hole to achieve axial positioning of the bearing 106c, ensuring the convenience of assembly and the reliability of installation.

[0030] Furthermore, the bearing housing 106a is bolted to the fixed mounting base 101, which is simple and reliable.

[0031] Please see Figure 3 and Figure 4 The hinge assembly 104 includes a lower mounting seat 104a fixedly mounted on the bottom mounting plate 103 and an upper mounting seat 104b fixedly mounted on the insert mounting plate 105. Each upper mounting seat 104b is rotatably connected to the corresponding lower mounting seat 104a through a hinge shaft 104c, which is simple and reliable.

[0032] Specifically, each lower mounting base 104a has a lower lug 104a1 extending toward the upper mounting base 104b, and each lower lug 104a1 has a first through hole. Each upper mounting base 104b has two upper lugs 104b1 extending toward the lower mounting base 104a. The two upper lugs 104b1 of the upper mounting base 104b form a mounting groove 104b2 that matches the corresponding lower lug 104a1. Each of the two upper lugs 104b1 of the upper mounting base 104b has a second through hole coaxially formed, and each second through hole has a sleeve 104d installed in it.

[0033] After the lower lug 104a1 is inserted into the mounting groove 104b2, the first through hole is made coaxial with the two inserts 104d. The hinge shaft 104c is simultaneously inserted into the corresponding first through hole and the inserts 104d at both ends of the first through hole. One end of the hinge shaft 104c has a radially protruding limiting end 104c1, and the other end is inserted with a second cotter pin 104e. This achieves the hinge while ensuring the convenience of assembly and the reliability of installation.

[0034] Furthermore, the lower mounting base 104a is bolted to the bottom mounting plate 103, and the upper mounting base 104b is bolted to the insert mounting plate 105, which is simple and reliable.

[0035] Please see Figure 6The lifting drive assembly 102 includes a component mounting plate 102a, a drive cylinder 102b, a push plate 102d parallel to the component mounting plate 102a near the bottom mounting plate 103, and two guide rods 102c parallel to both sides of the drive cylinder 102b. The push plate 102d is fixedly connected to the side of the bottom mounting plate 103 away from the insert mounting plate 105. The component mounting plate 102a is fixedly mounted on the fixed mounting base 101, and the cylinder body of the drive cylinder 102b is fixedly mounted on the component mounting plate 102a. Mounting plate 102a, the outer end of the piston rod of the drive cylinder 102b is fixedly connected to the push plate 102d. Two guide rod sleeves 102e, each adapted to the corresponding guide rod 102c, are fixedly mounted on the mounting plate 102a. One end of each guide rod 102c is inserted into the corresponding guide rod sleeve 102e with a shaft hole, and the other end of each guide rod 102c is fixedly connected to the push plate 102d, thereby ensuring the stability and reliability of the drive cylinder 102b driving the push plate 102d to rise and fall.

[0036] Please see Figure 8 When the piston rod of the drive cylinder 102b lowers the bottom mounting plate 103 to its lowest position by pulling down the push plate 102d, the insert mounting plate 105 is parallel to the bottom mounting plate 103; when the piston rod of the drive cylinder 102b pushes the bottom mounting plate 103 to its highest position by pushing the push plate 102d upward, the insert mounting plate 105 rises together with the bottom mounting plate 103 and rotates by a set angle relative to the width direction of the bottom mounting plate 103.

[0037] Example 2:

[0038] Please see Figure 1 , Figure 9 and Figure 10 A cold stamping die lower die includes a lower die base 200 and at least one set of shaping insert corner mechanism of Embodiment 1. The lower die base 200 has recessed corner mechanism mounting grooves 201 corresponding to each fixed mounting seat 101. Each fixed mounting seat 101 is fixedly installed at the bottom of the corresponding corner mechanism mounting groove 201. Each insert mounting plate 105 protrudes outward from the corresponding corner mechanism mounting groove 201. Furthermore, each insert mounting plate 105 has a plurality of shaping inserts 300 that rotate synchronously with it fixedly installed.

[0039] Therefore, by controlling the cornering mechanism of the cornering block, the shaping insert 300 can automatically rotate inside the mold, thereby satisfying the function of changing the stamping direction. This will not affect the production efficiency of cold stamping mold production, nor will it have a negative impact on stability.

[0040] Typically, the shaped insert 300 is fixed to the insert mounting plate 105 with bolts, which not only ensures the reliability of the installation, but also makes it easy to replace the insert mounting plate 105 with different structures according to actual needs, or to install the insert mounting plate 105 in different positions, making it extremely versatile.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
