Description

Technical Field

[0001] The utility model relates to the technical field of processing molds, in particular to a trimming mold for hollow convex tooth forgings. Background Art

[0002] Hollow convex tooth forgings are also called cam forgings. They are components with curved profiles or grooves. Cam mechanisms are generally high-pair mechanisms consisting of three components: cams, followers, and frames. Cams usually rotate continuously at a constant speed. Followers are designed according to usage requirements to achieve regular movements, so that cam mechanisms can achieve complex movement requirements. They are widely used in various automated and semi-automated mechanical devices.

[0003] During the processing of hollow convex tooth forgings, the edges of the blanks need to be cut to ensure the precision of the hollow convex tooth forgings. However, the cutters of traditional forging trimming dies are mostly one-piece structures and can only cut forgings of a single type and size. This results in manufacturers having to customize cutters of various types and sizes, increasing production and loss costs. For this reason, the utility model provides a trimming die for hollow convex tooth forgings to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a trimming die for hollow convex tooth forgings, which solves the technical problem that the cutters of traditional forging trimming dies are mostly of an integrated structure and can only perform cutting processing on forgings of a single type and size, which causes manufacturers to have to customize cutters of various types and sizes, thereby increasing production and loss costs.

[0007] Beneficial effects: The trimming die for hollow convex tooth forgings can use a cutter to cut the convex teeth of the forgings during the closing process of the upper die and the lower die. After replacing the cutter, convex teeth of forgings of different sizes can be cut. The cut waste will fall into the guide tube and slide out, which can be convenient for collecting the waste. After the cutting action is completed, the forging is rotated at a certain angle so that the cutter can face the next convex tooth to be cut, thereby achieving continuous trimming with a high degree of automation. On the other hand, the position of the cutter is adjustable and can be suitable for cutting forgings of different diameters. It has good versatility and reduces the manufacturer's purchase and loss costs.

DETAILED DESCRIPTION

[0018] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0019] See Figures 1 to 4 As shown, a trimming die for hollow convex tooth forgings comprises a lower die 1 and an upper die 2 located above the lower die 1, wherein the upper sides of the four corners of the lower die 1 are provided with guide grooves 13, the bottoms of the guide grooves 13 are provided with damping springs 14, and the four corners of the upper die 2 are fixed with guide columns 21, the bottom ends of the guide columns 21 extend into the adjacent blanking grooves 11 to abut against the damping springs 14;

[0020] Specifically, the output end of the hydraulic equipment presses the upper mold 2 to descend. When the upper mold 2 descends and closes with the lower mold 1, the guide column 21 slides downward along the blanking chute 11, playing a good guiding role and ensuring the precision of cutting. Conversely, when the upper mold 2 moves away from the lower mold 1, under the elastic force of the damping spring 14, the upper mold 2 slowly moves up, thereby realizing the separation of the upper mold 2 and the lower mold 1.

[0021] Further, a translation assembly 3 is installed on the lower side of the upper mold 2, and the translation assembly 3 includes a slide rail 31 fixedly connected to the lower side of the upper mold 2, a first motor 32 is fixedly connected to one side of the slide rail 31, a screw rod 33 is rotatably connected between the two side end surfaces of the slide rail 31, the screw rod 33 is threadedly connected to a slider 34 that can slide linearly along the slide rail 31, and an assembly seat 35 with an opening at the bottom is fixedly connected to the lower side of the slider 34, and first bolts 36 are threadedly connected to both sides of the assembly seat 35;

[0022] Specifically, the first motor 32 drives the screw rod 33 to rotate, the screw rod 33 threadably drives the slider 34, and the slider 34 drives the assembly seat 35, which can change the position of the cutter 4. The output number of turns of the first motor 32 is controlled according to the size of the hollow convex tooth forging, which can be suitable for cutting forgings of different diameters.

[0024] Specifically, screwing the first bolt 36 into the limiting groove 42 can prevent the plug-in block 41 from escaping from the assembly seat 35, thereby enabling the assembly of the cutter 4. Replacing different cutters 4 can be suitable for hollow convex tooth forgings with different convex tooth structures, and has strong applicability.

[0025] Furthermore, a rotation assembly 5 is installed in the middle of the lower mold 1, and the rotation assembly 5 includes an equipment cavity 51 located in the lower mold 1, a second motor 52 is fixed to the bottom of the equipment cavity 51 by screws, an output end of the second motor 52 passes through the lower mold 1 and is fixedly connected to a bearing seat 53, a positioning module 6 is fixed to the upper side of the bearing seat 53 by screws, and the positioning module 6 is adapted to the hollow groove of the forging;

[0026] Specifically, the second motor 52 drives the bearing seat 53 to rotate, and the bearing seat 53 can drive the positioning module 6 to rotate, and according to the different convex tooth spacings of the hollow convex tooth forgings, the second motor 52 is controlled to rotate at a certain angle each time, and the convex tooth position of each cutting can be rotated;

[0027] Preferably, the load-bearing seat 53 is rotationally connected to the lower mold 1 , and when the load-bearing seat 53 is subjected to force, the force is transmitted to the lower mold 1 , thereby preventing the second motor 52 from being damaged.

[0028] Furthermore, the rotation assembly 5 is detachably connected to a positioning module 6 so that the positioning module 6 can rotate. A plurality of threaded holes 54 are provided on the upper side of the load-bearing seat 53. Each of the threaded holes 54 corresponds to a second bolt 55. The positioning module 6 is provided with through holes having the same number as the threaded holes 54. The second bolts 55 are threadedly connected to the threaded holes 54 after passing through the through holes.

[0029] Specifically, it is convenient to install the positioning module 6, wherein the positioning module 6 is a spline structure. After the positioning module 6 is adapted to the hollow groove of the hollow convex tooth forging, the hollow convex tooth forging can be prevented from rotating and shifting, and the load-bearing seat 53, the positioning module 6 and the hollow convex tooth forging can be kept rotating synchronously.

[0030] Furthermore, a blanking chute 11 is provided on the upper side of the lower mold 1, and a material guide cylinder 12 arranged obliquely is fixedly connected to the bottom end of the blanking chute 11, and the blanking chute 11 is arranged opposite to the cutting position of the cutter 4, and the moving path of the cutter 4 intersects the rotation axis of the positioning module 6 at right angles;
