[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] See also Figure 1 - Figure 4 The utility model provides an antimony-free friction-reducing washer forming device, comprising: a base 1 and a forming die base 2 spaced apart at the top center of the base 1;

[0028] A punching die head 3 is arranged above the forming die base 2, and the punching die head 3 is lifted and lowered along the height direction of the base 1 by a power mechanism arranged on the base 1;

[0029] A U-shaped fixing seat 4 is arranged at a distance from one side of the top of the base 1, and waist hole grooves are formed on both sides of the fixing seat 4;

[0030] A loading box 5 is fixedly mounted on the top of the fixing seat 4, wherein the size of the loading box 5 is smaller than the slot size of the fixing seat 4, and the size of the interior of the loading box 5 is compatible with the size of the interior of the forming die base 2;

[0031] A push plate 6 is slidably arranged on the bottom wall of the fixed seat 4, and both side surfaces of the push plate 6 are rotatably connected with a connecting rod 7 through a supporting shaft passing through the waist hole groove. One end of the connecting rod 7 is movably connected to the stamping die 3 through a connecting shaft, wherein the thickness of the push plate 6 is consistent with the thickness of the raw material sheet, that is to say, when loading, the push plate 6 can only push out one raw material sheet at a time.

[0032] Two groups of support blocks 8 are symmetrically fixedly installed on the top of the base 1, the forming mold base 2 is fixedly installed between the opposite surfaces of the two groups of support blocks 8, two support frames 9 are symmetrically fixedly installed on one side of the top of the base 1, and the fixing base 4 is fixedly installed on the top of the support frame 9.

[0033] After the punching die 3 is moved down, the punching die 3 is driven by the driving mechanism to move the punching die 3 downwards, so that it cooperates with the punching die 3 to achieve the purpose of punching the gasket. In the process of the punching die 3 moving downwards, the connecting rod 7 can be driven to rotate by the connecting shaft, and at the same time, the connecting rod 7 drives the push plate 6 to slide inside the fixed seat 4 along the waist hole groove under the limiting action of the supporting shaft, so that the bottom of the feeding box 5 opens and the raw material sheet falls onto the fixed seat 4. At this time, the punching die 3 completes the punching and moves up, and at the same time drives the connecting rod 7 to move up and reset, and drives the push plate 6 to move and reset under the action of the connecting rod 7, so that the raw material is pushed into the forming die 2 for stamping and forming through the push plate 6. The above operation is repeated, so as to achieve the effect of automatic feeding of raw materials, without the need for personnel to feed materials, reducing the risk of accidents and the work intensity of personnel, and effectively improving the processing efficiency and convenience of use.

[0034] Furthermore, the power mechanism includes a mounting frame 10 fixedly mounted on the top of the base 1 and in the shape of a gantry, and a stamping hydraulic cylinder 11 fixedly mounted on the top of the mounting frame 10 . The output end of the stamping hydraulic cylinder 11 passes through the mounting frame 10 and is connected to the stamping die 3 .

[0035] Specifically, during stamping, the stamping die head 3 is driven to rise and fall by the stamping hydraulic cylinder 11, so that the stamping die head 3 is used in conjunction with the forming die base 2 to achieve the purpose of stamping and forming the gasket.

[0036] Furthermore, a material discharge mechanism is provided in the forming die base 2;

[0037] The material unloading mechanism includes a material unloading push plate 14 arranged in the forming die base 2 and a telescopic cylinder 15 fixedly installed on one side of the forming die base 2. The output end of the telescopic cylinder 15 passes through the forming die base 2 and is connected to the material unloading push plate 14.

[0038] A material discharge guide plate 16 is fixedly installed on the surface of the opening of the forming die base 2, and a collection box 17 is placed on the top of the base 1 and below the forming die base 2. During use, a finished product storage box can be placed below the material discharge guide plate 16 to facilitate the collection of finished products.

[0039] Specifically, after the stamping die 3 and the forming die base 2 are separated by stamping, the waste generated by stamping falls into the collection box 17 through the leakage hole on the forming die base 2. At the same time, the telescopic cylinder 15 drives the unloading push plate 14 to move, so that the finished products and remaining raw materials in the forming die base 2 can be pushed out uniformly, and are discharged and collected through the unloading guide plate 16.

[0040] Furthermore, a plurality of supporting feet 18 are fixedly installed at the four corners of the bottom of the base 1 , and an anti-slip pad is fixedly installed at the bottom of the supporting feet 18 .

[0041] Specifically, by providing the supporting feet 18, the supporting stability of the base 1 can be ensured, and under the action of the anti-slip pad, the friction between the supporting feet 18 and the ground can be enhanced, thereby improving the stability of processing and use. Example

[0042] Based on Example 1, in this embodiment: two limiting guide rods 12 that slide with the mounting frame 10 are symmetrically fixedly installed on the top of the stamping die 3, the cross-section of the limiting guide rod 12 is T-shaped, and a spring 13 is sleeved on the surface of the limiting guide rod 12, and the two ends of the spring 13 are respectively connected to the ends of the mounting frame 10 and the limiting guide rod 12.

[0043] The technical solution provided by this embodiment is: during the lifting and lowering of the stamping die head 3, the limiting guide rod 12 can be synchronously driven to slide on the mounting frame 10, and the spring 13 can be intermittently compressed, so that the spring 13 can buffer the stamping pressure, avoid damage to the forming die base 2, and extend the service life.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
