Description

Technical Field

[0001] The present invention belongs to the technical field of metal processing, and specifically relates to a forming device for cam processing. Background Art

[0002] Powder stamping (which belongs to powder metallurgy process) is an efficient and low-cost method for manufacturing cams, especially suitable for medium to large batch production.

[0003] Existing powder stamping equipment has the following defects when manufacturing cams: ①. After the powder is filled into the mold, particles are likely to form an arch structure at the narrow part of the mold, hindering the filling of the lower-layer powder, thus affecting the stamping effect of the cam.

[0004] ②. The metal powder overflowing from the escape groove is not recycled, resulting in waste of resources. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a forming device for cam processing, so as to solve the technical problems that after the powder is filled into the mold, the powder is likely to form an arch structure at the narrow part of the mold, hindering the filling of the lower-layer powder, thus affecting the stamping effect of the cam, and the metal powder overflowing from the escape groove is not recycled, resulting in waste of resources.

[0006] To achieve the foregoing invention purpose, the technical solution adopted by the present invention includes: a forming device for cam processing, including a bracket, a stamping part, a bearing part, and a feeding mechanism. The stamping part is slidably arranged on the bracket along the vertical direction. The stamping part has a stamping end. The bearing part is fixed on the bracket. The bearing part has a mold cavity. When the stamping part moves downward, the stamping end can penetrate into the mold cavity to press the powder into shape. A jacking mechanism for ejecting the cam is arranged at the lower end of the bearing part; A support plate is fixed on the bracket. The support plate is horizontally arranged. The bearing part is arranged on the support plate, and the lower end of the bearing part extends to the lower side of the support plate. An escape hole communicating with the mold cavity is opened on the outside of the bearing part. The escape hole is located below the support plate. A collection box is arranged below the support plate, and the collection box covers the outside of the bearing part; A vibration mechanism is arranged on the support plate. The vibration mechanism includes a slider slidably arranged on the support plate. A knocking part is arranged at one end of the slider close to the collection box. During the sliding process of the slider on the support plate, the knocking part can knock the collection box to vibrate the collection box and the bearing part; A driving mechanism is provided on the mounting plate. The driving mechanism includes a disk body, which is rotatably arranged at the bottom of the support plate through a rotating shaft. A connecting rod is arranged between the disk body and the slider. One end of the connecting rod is hinged to the disk body, and the hinge point of the connecting rod and the disk body deviates from the rotating connection point of the disk body and the support plate. The end of the connecting rod away from the disk body is hinged to the slider. The feeding mechanism includes a feeding box, which is slidably arranged on the top of the support plate along the sliding direction of the slider. The feeding box releases the powder inside it during the sliding process so that the powder enters the mold cavity. A first transmission component is arranged between the feeding box and the disk body. The first transmission component includes a first gear and a first rack meshing with the first gear. The first gear is fixedly connected to the disk body coaxially, and the first rack is fixedly connected to the feeding box. By moving the feeding box, the first rack can be driven to move synchronously to make the first gear rotate.

[0007] Compared with the prior art, the advantages of the present invention include: (1) A molding device for cam processing provided by the present invention. The powder escaping from the mold cavity can enter the inside of the collection box through the powder escape hole and be collected by the collection box for subsequent recycling treatment, realizing the recycling of the powder and having environmental protection.

[0008] (2) A molding device for cam processing provided by the present invention. Since the knocking part vibrates the pressure-bearing part by knocking the collection box, directly knocking the pressure-bearing part is avoided. Therefore, the collection box has a protective effect on the pressure-bearing part, effectively reducing the adverse impact on stamping caused by the knocking part directly knocking on the pressure-bearing part and changing the shape of the mold cavity.

[0009] (3) A molding device for cam processing provided by the present invention. During the sliding process of the slider on the support plate, the knocking part can knock the collection box to make the collection box and the pressure-bearing part vibrate. The vibration can increase the fluidity of the powder in the mold cavity, reduce the possibility of the powder forming an arch structure at the narrow part of the mold cavity, and does not affect the filling of the lower-layer powder, making the powder filling more uniform.

[0010] (4) A molding device for cam processing provided by the present invention. Since the powder escaping from the powder escape hole is easily adhered to the side wall of the collection box, the vibration will cause the powder on the side wall of the collection box to fall to the bottom of the collection box for further recycling treatment.

[0011] (5) A molding device for cam processing provided by the present invention. By combining the feeding operation of the feeding box with the vibration of the vibration mechanism through the first transmission component, the vibration mechanism can be vibrated by the first transmission component while the feeding box is feeding, with a high degree of automation, reducing the drive source for driving the vibration mechanism to operate and saving production costs.

[0012] Further, the right side of the lower end of the collection box is inclined downward, and a discharge port communicating with the inside of the collection box is provided on the right side of the lower end of the collection box.

[0013] Further, a rubber block is provided on the collection box, and the knocking part makes the collection box vibrate by knocking the rubber block.

[0014] Further, a square accommodation cavity is provided inside the feeding box. The length direction of the accommodation cavity is consistent with the sliding direction of the slider. A dispersing roller is arranged inside the accommodation cavity along the width direction of the accommodation cavity. Dispersing claws are provided on the dispersing roller. Both ends of the roller shaft of the dispersing roller are respectively hinged with a first rod body and a second rod body. The ends of the first rod body and the second rod body far away from the dispersing roller extend out of the feeding box in the length direction of the accommodation cavity away from the dispersing roller and are fixedly connected with the support plate. A second transmission assembly is arranged between the accommodation cavity and the dispersing roller. The second transmission assembly includes a second gear and a second rack engaged with the second gear. The second rack is fixed on the side wall of the accommodation cavity along the length direction of the accommodation cavity, and the second gear is coaxially and fixedly connected with the roller shaft of the dispersing roller.

[0015] Further, the second rack is engaged above the second gear.

[0016] Further, a partition board is arranged inside the accommodation cavity along the length direction of the accommodation cavity. A strip-shaped through hole for the roller shaft of the dispersing roller to move is provided on the partition board. The length direction of the strip-shaped through hole is consistent with the length direction of the accommodation cavity. The second gear and the second rack are located on the side of the partition board away from the center of the accommodation cavity, and the dispersing roller is located on the side of the partition board close to the center of the accommodation cavity.

[0017] Further, a filler groove is arranged inside the accommodation cavity close to the mold cavity. A filler port communicating with the outside is provided at the bottom of the filler groove. A sieve plate is arranged on the side of the accommodation cavity close to the mold cavity. The sieve plate separates the filler groove from the accommodation cavity.

[0018] Further, a cover plate for closing the filler port is provided at the bottom of the feeding box. The cover plate is slidably arranged at the bottom of the feeding box along the length direction of the accommodation cavity. An elastic member is arranged between the cover plate and the feeding box. A push rod is arranged at one end of the cover plate close to the mold cavity. One end of the push rod is connected with the cover plate, and the other end extends in the length direction of the accommodation cavity towards the mold cavity. A limiting block is arranged on the support plate. The limiting block is located on the side of the mold cavity opposite to the feeding box. When the feeding box moves towards the mold cavity, the limiting block restricts the push rod to make the cover plate move away from the mold cavity to open the filler port. When the feeding box moves away from the mold cavity, the cover plate moves towards the mold cavity under the action of the elastic member to re-close the filler port. Description of the Drawings

[0027] Please refer to Figures 1-7 ,the present invention provides a technical solution: refer to Figures 1-2, A forming device for cam machining, including a bracket 31, a stamping part 1, a pressure-bearing part 2 and a feeding mechanism. The stamping part 1 is slidably arranged along the vertical direction on the bracket 31. The stamping part 1 has a stamping end 3. In this embodiment, the end face of the stamping end 3 should be cam-shaped. The pressure-bearing part 2 is fixed on the bracket 31. The pressure-bearing part 2 has a die cavity 4. Correspondingly, the shape of the die cavity 4 should be adapted to the shape of the stamping end 3, which is cam-shaped in this embodiment. It should be noted that the shapes of the die cavity 4 and the stamping end 3 are specifically designed according to the products to be produced, and are not specifically limited, and the protection scope of the present invention should not be reduced due to their specific shapes. When the stamping part 1 moves downward, the stamping end 3 can penetrate into the die cavity 4 to press and form the powder. A jacking mechanism 5 for jacking out the cam is arranged at the lower end of the pressure-bearing part 2. After the cam is pressed and formed, the jacking mechanism 5 moves upward to jack out the pressed cam out of the die cavity 4.

[0028] Refer to Figure 2 , A support plate 6 is fixed on the bracket 31. The support plate 6 is horizontally arranged. The pressure-bearing part 2 is arranged on the support plate 6, and the lower end of the pressure-bearing part 2 extends to the lower side of the support plate 6. A material escape hole 7 communicating with the die cavity 4 is opened on the outside of the pressure-bearing part 2. The material escape hole 7 is used for the escape of excess powder during pressing and forming. Specifically in the design, it should be inclined upward at an inclination angle of 5-15 degrees. The material escape hole 7 is located below the support plate 6. A collection box 8 is arranged below the support plate 6. The collection box 8 covers the outside of the pressure-bearing part 2, that is, the collection box 8 covers the outside of the material escape hole 7. That is, one end of the material escape hole 7 far from the die cavity 4 is communicated with the inside of the collection box 8. The powder escaping from the die cavity 4 can enter the inside of the collection box 8 through the material escape hole 7 and be collected by the collection box 8 for subsequent recycling treatment.

[0029] Refer to Figures 1-2 , A vibration mechanism is arranged on the support plate 6. The vibration mechanism includes a slider 9 slidably arranged on the support plate 6. A knocking part 10 is arranged at one end of the slider 9 close to the collection box 8. During the sliding process of the slider 9 on the support plate 6, the knocking part 10 can knock the collection box 8 to make the collection box 8 and the pressure-bearing part 2 vibrate. Vibration can increase the fluidity of the powder in the die cavity 4, reduce the possibility of the powder forming an arch structure at the narrow part of the die cavity 4, does not affect the filling of the lower-layer powder, and makes the powder filling more uniform. In addition, since the powder escaping from the material escape hole 7 is easily adhered to the side wall of the collection box 8, vibration will make the powder on the side wall of the collection box 8 fall to the bottom of the collection box 8 for further recycling treatment. In addition, since the knocking part 10 vibrates the pressure-bearing part 2 by knocking the collection box 8, the direct knocking of the pressure-bearing part 2 is avoided. Therefore, the collection box 8 has a protective effect on the pressure-bearing part 2, effectively reducing the adverse impact on stamping caused by the knocking part 10 directly knocking on the pressure-bearing part 2 and changing the shape of the die cavity 4.

[0030] A driving mechanism is provided on the mounting plate. The driving mechanism is used to drive the slider 9 to reciprocate, so that the knocking part 10 continuously knocks the collection box 8, and continuous knocking will cause the collection box 8 and the pressure-bearing part 2 to vibrate continuously.

[0031] Refer to Figures 1-2 , the driving mechanism includes a disk body 13. The disk body 13 is rotatably arranged at the bottom of the support plate 6 through a rotating shaft. A connecting rod 14 is arranged between the disk body 13 and the slider 9. One end of the connecting rod 14 is hinged to the disk body 13, and the hinge point of the connecting rod 14 and the disk body 13 deviates from the rotating connection point of the disk body 13 and the support plate 6, that is, the connecting rod 14 is eccentrically connected to the disk body 13. The end of the connecting rod 14 far from the disk body 13 is hinged to the slider 9. The disk body 13, the connecting rod 14 and the slider 9 form a crank-slider mechanism. By continuously rotating the disk body 13, the slider 9 can make continuous reciprocating motions.

[0032] The feeding mechanism includes a feeding box 15. The feeding box 15 is slidably arranged on the top of the support plate 6 along the sliding direction of the slider 9. The feeding box 15 releases the powder inside it during the sliding process, so that the powder fills into the mold cavity 4. A first transmission component is arranged between the feeding box 15 and the disk body 13. The first transmission component includes a first gear 16 and a first rack 17 meshing with the first gear 16. The first gear 16 is coaxially and fixedly connected to the disk body 13, that is, the first gear 16 is sleeved on the rotating shaft and fixedly connected to the first gear 16. The first rack 17 is fixedly connected to the feeding box 15. Specifically, a sliding hole penetrating the support plate 6 in its thickness direction is opened at the top of the support plate 6. The sliding hole is strip-shaped, and its length direction is consistent with the sliding direction of the slider 9 and the feeding box 15. A connecting block is arranged at the bottom of the feeding box 15, and the lower end of the connecting block extends downward along the sliding hole and passes through the sliding hole and is fixedly connected to the first rack 17. By moving the feeding box 15, the first rack 17 can be driven to move synchronously, so that the first gear 16 meshing with the first rack 17 rotates. The rotation of the first gear 16 drives the disk body 13 to rotate, and the rotation of the disk body 13 causes the slider 9 to make reciprocating motions, and then the knocking part 10 continuously knocks the rubber block 12 to vibrate the collection box 8 and the pressure-bearing part 2. It should be noted that one reciprocating motion of the feeding box 15 is a feeding process of the feeding box 15, that is, the feeding box 15 moves from the initial position to the mold cavity 4, and after discharging, it returns to the initial position. The stamping operation is carried out only after the feeding operation is completed. During the reciprocating motion of the feeding box 15, the vibration mechanism will generate a vibration effect through the first transmission component.

[0033] By combining the feeding operation of the feeding box 15 with the vibration of the vibration mechanism through the first transmission component, the vibration mechanism can be vibrated through the first transmission component while the feeding box 15 is feeding, with a high degree of automation, reducing the drive source for driving the vibration mechanism to operate and saving production costs.

[0034] Refer to Figure 2, in this embodiment: The right side of the lower end of the collection box 8 is inclined downward, that is, a slope is formed at the lower end of the collection box 8, so that the powder falling into the collection box 8 can naturally slide down along the slope to the lower right side under the action of gravity. An exhaust port communicating with the inside of the collection box 8 is provided on the right side of the lower end of the collection box 8 (that is, the lower part of the lower end of the collection box 8). The powder in the collection box 8 accumulates above the exhaust port through the slope. When the exhaust port is opened, most of the powder can be removed, and the cleaning is relatively thorough. The vibration of the vibration mechanism will also cause the powder to accelerate and gather towards the lower right side of the lower end of the collection box 8. In addition, when the powder is discharged from the exhaust port, the vibration of the vibration mechanism will also reduce the possibility of the powder clogging the exhaust port.

[0035] Furthermore, an exhaust valve 11 is provided on the exhaust port.

[0036] Refer to Figure 1 , in this embodiment: A rubber block 12 is provided on the collection box 8, and the knocking part 10 knocks the rubber block 12 to vibrate the collection box 8.

[0037] The rubber block 12 has two functions here: ①. The rubber block 12 can prevent the knocking part 10 from directly knocking the collection box 8, and has a buffering and protecting effect on the collection box 8.

[0038] ②. The rubber block 12 can absorb the sound generated by the knocking of the knocking part 10 and has a noise reduction function.

[0039] Refer to Figure 3 , 5 , in this embodiment: The inside of the feeding box 15 has a square accommodating cavity. The length direction of the accommodating cavity is consistent with the sliding direction of the slider 9. A dispersing roller 18 is arranged inside the accommodating cavity along the width direction of the accommodating cavity. Dispersing claws 19 are arranged on the dispersing roller 18, and the dispersing claws 19 agitate the powder inside the feeding box 15 during rotation.

[0040] When the powder is damp, it is easy to form aggregates, which reduces the fluidity of the powder. During pressing, the aggregates will cause local over-compaction, that is, the particle gaps inside the aggregates are small, but pores are formed in the surrounding area due to lack of powder; the risk of stress concentration means that the interface between the aggregates and the loose powder is likely to become a crack source. By rotating the dispersing claws 19, the aggregates can be broken up, enhancing the fluidity of the powder. The enhanced fluidity of the powder will make the overall density more uniform during the stamping operation and the stamping effect better. In addition, the agitation of the powder by the dispersing claws 19 causes the powder to collide and rub against each other, so that the powder has a certain grinding effect, making the powder closer to a regular spherical shape. The fluidity of spherical powder is better than that of irregular particles, so the stamping effect can be further improved.

[0041] At both ends of the roller shaft of the stirring roller 18, a first rod body 20 and a second rod body 21 are respectively hinged. The ends of the first rod body 20 and the second rod body 21 far from the stirring roller 18 extend out of the feeding box 15 in the length direction of the accommodating cavity away from the stirring roller 18 (the second rod body 21 and the first rod body 20 can move relative to the feeding box 15), and are fixedly connected to the support plate 6. Since the stirring roller 18 is fixed on the support plate 6 through the first rod body 20 and the second rod body 21, that is, its position on the support plate 6 is relatively fixed. Therefore, the back-and-forth movement of the feeding box 15 will cause the stirring roller 18 to move back and forth in the accommodating cavity. Thus, when the stirring roller 18 rotates, its stirring range is larger, further improving the stirring effect.

[0042] A second transmission assembly is arranged between the accommodating cavity and the stirring roller 18. The second transmission assembly includes a second gear 22 and a second rack 23 meshing with the second gear 22. The second rack 23 is fixed to the side wall of the accommodating cavity along the length direction of the accommodating cavity, and the second gear 22 is coaxially and fixedly connected to the roller shaft of the stirring roller 18. The back-and-forth movement of the feeding box 15 will cause the stirring roller 18 to move back and forth in the accommodating cavity, and then drive the second gear 22 to move back and forth. Under the action of the second rack 23, the second gear 22 will synchronously drive the stirring roller 18 to rotate during the back-and-forth movement of the stirring roller 18 in the accommodating cavity.

[0043] By combining the movement of the feeding box 15 with the rotation of the stirring roller 18 through the second transmission assembly, the stirring roller 18 can be rotated by the second transmission assembly while the feeding box 15 is moving. The degree of automation is relatively high, reducing the use of the drive source for driving the rotation of the stirring roller 18 and saving the production cost.

[0044] It should be noted that the powder in the accommodating cavity should not be too much and should be below the second rack 23 to reduce the influence of the powder on the transmission between the second rack 23 and the second gear 22.

[0045] In this embodiment: The second rack 23 meshes above the second gear 22, that is, the tooth grooves of the second rack 23 face downward. When the powder adheres to the second rack 23, it can fall off under the action of gravity. In addition, the vibration of the vibration mechanism will also make it difficult for the powder to adhere to the second rack 23.

[0046] Refer to Figure 6 In this embodiment: A partition plate 24 is arranged in the accommodating cavity along the length direction of the accommodating cavity. A strip-shaped through hole for the movement of the roller shaft of the stirring roller 18 is opened on the partition plate 24. The length direction of the strip-shaped through hole is consistent with the length direction of the accommodating cavity. The second gear 22 and the second rack 23 are located on the side of the partition plate 24 far from the center of the accommodating cavity, and the stirring roller 18 is located on the side of the partition plate 24 close to the center of the accommodating cavity. The partition plate 24 can reduce the possibility that the lifted powder falls onto the second gear 22 and the second rack 23, further reducing the influence of the powder on the transmission between the second rack 23 and the second gear 22.

[0047] Refer to Figure 5 Or 6. In this embodiment: A filler groove 25 is provided on one side of the accommodation cavity close to the mold cavity 4. A filler port communicating with the outside is opened at the bottom of the filler groove 25. A sieve plate 26 is provided on one side of the accommodation cavity close to the mold cavity 4. The sieve plate 26 separates the filler groove 25 from the accommodation cavity. During the reciprocating movement of the stirring and dispersing roller 18, the powder lifted can be thrown towards the sieve plate 26. The powder meeting the particle size requirements falls into the filler groove 25 after being sieved by the sieve plate 26. When the feeding box 15 moves to the position of the mold cavity 4, the powder in the filler groove 25 is discharged into the mold cavity 4 through the filler port to realize the filling of the powder in the mold cavity 4. And the sieved powder can reduce the particle size difference and improve the powder fluidity, thereby improving the stamping effect. In addition, the vibration of the vibration mechanism will accelerate the transportation of the powder in the accommodation cavity to the filler groove through the sieve plate, and at the same time reduce the possibility of the powder clogging the sieve plate.

[0048] Refer to Figure 5 Or 6. In this embodiment: The cross-section of the filler groove 25 is an isosceles trapezoid with a larger upper part and a smaller lower part. Through the above setting, when the filler port discharges the powder, the powder converges towards the bottom of the filler groove 25 under the action of the inclined surface of the filler groove 25.

[0049] Refer to Figure 3 Or 7. In this embodiment: A cover plate 27 for closing the filler port is provided at the bottom of the feeding box 15. The cover plate 27 is slidably arranged at the bottom of the feeding box 15 along the length direction of the accommodation cavity. An elastic member 28 is provided between the cover plate 27 and the feeding box 15. The elastic member 28 is a spring. One end of the spring is connected to the cover plate 27, and the other end is connected to the feeding box 15. A push rod 29 is provided at one end of the cover plate 27 close to the mold cavity 4. One end of the push rod 29 is connected to the cover plate 27, and the other end extends towards the direction close to the mold cavity 4 along the length direction of the accommodation cavity. In this embodiment, the end of the push rod 29 away from the cover plate 27 extends out of the feeding box 15 along the length direction of the accommodation cavity. A limiting block 30 is provided on the support plate 6. The limiting block 30 is located on the side of the mold cavity 4 facing away from the feeding box 15.

[0050] When the feeding box 15 moves towards the direction close to the mold cavity 4, the limiting block 30 restricts the push rod 29 to make the cover plate 27 move away from the mold cavity 4 to open the filler port. At this time, the filler port is just above the mold cavity 4, and the powder falls from the filler port into the mold cavity 4. When the feeding box 15 moves away from the mold cavity 4, the cover plate 27 moves towards the direction close to the mold cavity 4 under the action of the elastic member 28 to re-close the filler port. Through the push rod, the limiting block and the elastic member, during the movement of the feeding box, the automatic closing and opening of the filler port are realized, and the operation is relatively simple.

[0051] It should be understood that the above embodiments are only used to illustrate the technical concept and features of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can be made.
