Description

Technical Field

[0001] This utility model relates to the field of processing and forming technology, and in particular to a recessed part forming device. Background Technology

[0002] In industrial production, it is often necessary to machine recesses into materials, such as on shafts or pipes. Chinese patent application number 202321311156.2 discloses a pipe long groove forming device, which includes a worktable with a feeding unit for conveying and placing pipes. A grooving unit is located at one end of the pipe on the worktable, and a pushing unit is located at the other end to push the pipe to the grooving unit. The grooving unit includes a base with corresponding upper and lower dies. The parting surfaces of the upper and lower dies each have a half-open cavity. When the upper and lower dies are closed, the two cavities form a complete pipe cavity with open ends. A stamped protrusion extending along the length of the pipe is located at the center of the bottom of the upper cavity. The pushing unit includes a slider slidably connected to the worktable, with a push rod on the slider. The push rod abuts against one end of the pipe and pushes the pipe, causing the other end of the pipe to be inserted into the cavity through the cavity opening. While the patent document demonstrates the ability to machine long grooves into pipes, it cannot machine recesses into the sides of specific sections of the pipe, and demolding the pipe after stamping is difficult. Therefore, the shortcomings are quite obvious, and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a recess forming device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A recessed area forming device includes a base, a lifting seat slidably connected to the base, a lifting drive mechanism mounted on the base and used to drive the lifting seat to rise and fall, a lifting block slidably connected to the lifting seat, a lifting driver mounted on the lifting seat and used to drive the lifting block to rise and fall, and a recessed area forming assembly disposed below the lifting block. The recessed area forming assembly includes a fixed base, an elastic pull member, an elastic member, two symmetrically arranged swing arms, two symmetrically arranged sliders, and two symmetrically arranged pressure knives. Two driving inclined surfaces are symmetrically arranged on both sides of the bottom of the lifting block. Rotating cavities are provided on both sides of the fixed base. The two rotating cavities are respectively arranged one-to-one with the two swing arms. The middle part of the swing arm is rotatably connected to the two opposite side walls of the rotating cavity. The upper middle parts of the two swing arms are elastically connected via the elastic pull member. The top ends of the two swing arms respectively abut against the two driving inclined surfaces. The two sliders are horizontally slidably connected to the bottom of the fixed base. The two sliders are located between the bottom ends of the two swing arms. The bottom ends of the two swing arms are used to abut against the two sliders respectively. The two pressure knives are respectively mounted on the two sliders. The elastic member is clamped between the two sliders.

[0006] Furthermore, the bottom surface of the fixed base is recessed with a sliding cavity, the rotating cavity is connected to the sliding cavity, and guide rods are installed on the two opposite side walls of the sliding cavity, through which the two sliders slide.

[0007] Furthermore, the elastic element is a spring, which is sleeved outside the guide rod, and the two ends of the spring abut against the two sliders respectively.

[0008] Furthermore, a rotating block is rotatably connected to the top of the swing arm, and the rotating block rolls against the drive ramp.

[0009] Furthermore, the bottom surface of the slider is recessed with an insert hole, and the pressure knife is inserted into the insert hole, with the cutting edge of the pressure knife extending out of one side of the insert hole.

[0010] Furthermore, the recess forming device also includes a clamping mechanism mounted on the base, which is located below the fixed seat.

[0011] Furthermore, the clamping mechanism includes a clamping driver mounted on the base and two clamping components respectively mounted on the two output ends of the clamping driver. The clamping driver is used to drive the two clamping components to move closer or further away from each other. The clamping ends of the two clamping components are recessed with clamping grooves on the side where they are close to each other.

[0012] Furthermore, the thickness of the clamping end of one clamping component is greater than the thickness of the clamping end of another clamping component. The clamping end of the thicker clamping component has a recessed receiving groove in the middle. The receiving groove is used for the clamping end of the thinner clamping component to extend into. The receiving groove is formed by recessing from the side wall of the clamping groove of the clamping end of the thicker clamping component.

[0013] Furthermore, the recess forming device also includes a carrier disposed below the clamping mechanism, the carrier having a material loading cavity.

[0014] Furthermore, the lifting seat is equipped with a damper and a limiting component, and the base is provided with a limiting surface. Both the damper and the limiting component are located above the limiting surface, and both the damper and the limiting component are used to abut against the limiting surface.

[0015] The beneficial effects of this utility model are as follows: In practical applications, initially, the elastic element is in an extended state, applying a force that moves away from each other to the two sliders, ensuring that the sliders always contact the bottom end of the swing arm. The elastic tensioning element applies a force that moves closer to each other to the upper middle part of the two swing arms, ensuring that the top end of the swing arm always contacts the driving inclined surface. The material is placed manually or mechanically into the loading cavity of the carrier, with the top end of the material passing through the clamping end of the clamping mechanism. The clamping end of the clamping mechanism then holds the middle part of the material to ensure its stability and positional accuracy. Then, the lifting drive mechanism drives the lifting seat, along with the lifting block and the recessed forming assembly, to descend as a whole, so that the top of the clamped material is positioned between the two pressure knives. Next, the lifting driver drives the lifting block to descend, and the two driving inclined surfaces of the descending lifting block contact the top ends of the two swing arms respectively. As the lifting block descends, the distance between the two driving inclined surfaces gradually increases. The two swing arms are driven to move away from each other, causing them to swing. The bottom ends of the swinging arms move closer together, contacting and pressing against two sliders, which in turn bring the two pressure blades closer together. These pressure blades apply pressure to the top of the material to be formed, creating a recessed area. Finally, the lifting driver drives the lifting block to rise and reset. As the lifting block rises, the elastic force of the elastic member drives the top ends of the two swing arms closer together and reset, while the elastic force drives the two sliders to move away and reset, causing the pressure blades to release the material. The clamping end of the clamping mechanism also releases the material. Then, the lifting drive mechanism drives the lifting seat, along with the lifting block and the recessed area forming assembly, to rise and reset, facilitating recessed area forming for the next material. The formed material can then be removed manually or mechanically, and the material to be processed can be placed in the loading cavity of the carrier. This invention can reliably and stably form recessed areas on both sides of a material, with high efficiency in forming these areas. Attached Figure Description

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0025] like Figures 1 to 6As shown, this utility model provides a recessed area forming device, which includes a base 1, a lifting seat 2 that is slidably connected to the base 1, a lifting drive mechanism 3 installed on the base 1 and used to drive the lifting seat 2 to rise and fall, a lifting block 4 that is slidably connected to the lifting seat 2, a lifting driver 5 installed on the lifting seat 2 and used to drive the lifting block 4 to rise and fall, and a recessed area forming component 6 disposed below the lifting block 4. The recessed area forming component 6 includes a fixed base 7, an elastic pull member 8, an elastic member 9, two symmetrically arranged swing arms 10, two symmetrically arranged sliders 11, and two symmetrically arranged pressure knives 12. Two driving inclined surfaces 13 are symmetrically arranged on both sides of the bottom of the lifting block 4. Rotating cavities 14 are provided on both sides of the fixed base 7. The two rotating cavities 14 are respectively arranged one-to-one with the two swing arms 10. The middle part of the swing arm 10 is connected to the two phases of the rotating cavity 14. The two swing arms 10 are rotatably connected to the side walls. The upper middle parts of the two swing arms 10 are elastically connected via elastic tension members 8. The top ends of the two swing arms 10 respectively abut against the two driving inclined surfaces 13. The two sliders 11 are horizontally slidably connected to the bottom of the fixed base 7. The two sliders 11 are located between the bottom ends of the two swing arms 10. The bottom ends of the two swing arms 10 are used to abut against the two sliders 11 respectively. The two pressure knives 12 are respectively installed on the two sliders 11. The elastic member 9 is clamped between the two sliders 11. Specifically, the recessed position forming device also includes a clamping mechanism 25 installed on the base 1. The clamping mechanism 25 is located below the fixed base 7. The recessed position forming device also includes a carrier 26 and a platform 27, both of which are installed below the clamping mechanism 25. The carrier 26 is installed on the platform 27 and has a material loading cavity. The lifting drive mechanism 3 and the lifting driver 5 can both be cylinders.

[0026] In practical applications, initially, the elastic element 9 is in an extended state, applying a force that keeps the two sliders 11 moving away from each other, ensuring that the sliders 11 always contact the bottom of the swing arm 10. The elastic element 8 applies a force that moves the two upper and middle parts of the two swing arms 10 closer together, ensuring that the top of the swing arm 10 always contacts the driving inclined surface 13. Material is placed manually or mechanically into the loading cavity of the carrier 26, with the top of the material passing through the clamping end of the clamping mechanism 25. The clamping end of the clamping mechanism 25 then holds the middle of the material to ensure its stability and positional accuracy. Then, the lifting drive mechanism 3 drives the lifting seat 2, along with the lifting block 4 and the recessed forming assembly 6, to descend as a whole, so that the top of the clamped material is positioned between the two pressure knives 12. Next, the lifting driver 5 drives the lifting block 4 to descend, with the two driving inclined surfaces 13 of the descending lifting block 4 contacting the tops of the two swing arms 10 respectively. As the lifting block 4 descends, the distance between the two driving inclined surfaces 13 gradually increases to drive... The tops of the two swing arms 10 move away from each other, causing the two swing arms 10 to swing. The bottoms of the swinging two swing arms 10 move closer to each other and abut against the two sliders 11, causing the two pressure knives 12 to move closer to each other. The two pressure knives 12, which are close to each other, apply pressure to the top of the material to be formed, so as to squeeze and form a recessed position at the top of the material. Finally, the lifting driver 5 drives the lifting block 4 to rise and reset. As the lifting block 4 rises, the elastic force of the elastic pull member 8 drives the tops of the two swing arms 10 to move closer to each other and reset. The elastic force of the elastic member 9 drives the two sliders 11 to move away from each other and reset, causing the two pressure knives 12 to release the material. The clamping end of the clamping mechanism 25 releases the material. Then, the lifting drive mechanism 3 drives the lifting seat 2, along with the lifting block 4 and the recessed position forming component 6, to rise and reset as a whole, so as to form a recessed position for the next material. The material after the recessed position is formed can be removed manually or mechanically, and the material to be processed can be placed in the material loading cavity of the carrier 26. During use, when the pressure cutter 12 is damaged, only the pressure cutter 12 needs to be replaced, reducing maintenance costs. Furthermore, depending on the required size and / or shape of the recessed area to be machined on the material, different sizes and / or shapes of pressure cutters 12 can be used. This invention can reliably and stably machine recessed areas on both sides of a material, and the forming efficiency of the recessed areas is high.

[0027] In this embodiment, the bottom surface of the fixed base 7 is recessed with a sliding cavity 15, and two sliders 11 are slidably disposed within the sliding cavity 15, making the structure of the fixed base 7 and the sliders 11 compact. The rotating cavity 14 is connected to the sliding cavity 15, and the bottom end of the swing arm 10 can extend into the sliding cavity 15. Guide rods 16 are installed on the two opposite side walls of the sliding cavity 15, and the two sliders 11 slide through the guide rods 16. As the sliders 11 move closer to or further away from each other, the guide rods 16 guide the sliders 11, improving the movement stability of the sliders 11.

[0028] In this embodiment, the elastic element 9 is a spring, which is sleeved on the guide rod 16, with its two ends abutting against the two sliders 11 respectively. The guide rod 16 guides and positions the spring, improving its working stability and facilitating its assembly and disassembly.

[0029] Specifically, a fixing hole is provided on the side of the sliders 11 that are close to each other, and the end of the spring extends into the fixing hole. This structural design can fix and position the end of the spring, improve the working stability of the spring, and facilitate the assembly of the spring.

[0030] Specifically, there are two guide rods 16, which are arranged in parallel. Each slider 11 slides through both guide rods 16, and the pressure knife 12 is located between the two guide rods 16. This structural design further improves the movement stability of the slider 11.

[0031] Specifically, the elastic tension member 8 is a tension spring. Tension springs have a simple structure, good elasticity, low cost, and are easy to assemble and disassemble.

[0032] In this embodiment, a rotating block 17 is rotatably connected to the top of the swing arm 10, and the rotating block 17 rolls against the driving inclined surface 13. Specifically, the rotating block 17 is a wheel, a ball, or a bearing, etc. During the lifting process of the lifting block 4, the rolling contact between the rotating block 17 and the driving inclined surface 13 reduces frictional resistance and wear, and extends the service life of the lifting block 4 and the swing arm 10.

[0033] In this embodiment, the bottom surface of the slider 11 is recessed with an insert hole 18, and the pressure knife 12 is inserted into the insert hole 18, with the cutting edge of the pressure knife 12 extending out of one side of the insert hole 18. This structural design not only makes the slider 11 and the pressure knife 12 compact and facilitates the assembly of the pressure knife 12, but also improves the stability and positional accuracy of the pressure knife 12.

[0034] In this embodiment, the clamping mechanism 25 includes a clamping driver 19 mounted on the base 1 and two clamping members 20 respectively mounted on the two output ends of the clamping driver 19. The clamping driver 19 is used to drive the two clamping members 20 to move closer or further away from each other. The clamping ends of the two clamping members 20 that are close to each other are each provided with a clamping groove 21. Specifically, the clamping driver 19 can be a finger cylinder.

[0035] In practical applications, after the material is placed in the loading cavity of the carrier 26, the clamping driver 19 drives the two clamping members 20 to move closer to each other until the two clamping members 20 clamp the material in the clamping groove 21.

[0036] Specifically, the clamping groove 21 is a U-shaped groove, a V-shaped groove, or a circular arc groove. The clamping groove 21 designed in this way can not only stably clamp the material, but also support and correct the material's deviation.

[0037] In this embodiment, the thickness of the clamping end of one clamping member 20 is greater than the thickness of the clamping end of the other clamping member 20. A receiving groove 22 is recessed in the middle of the clamping end of the thicker clamping member 20, allowing the clamping end of the thinner clamping member 20 to extend into it. The receiving groove 22 is recessed from the side wall of the clamping groove 21 of the clamping end of the thicker clamping member 20, thus dividing the clamping groove 21 into two. When the clamping ends of the two clamping members 20 hold material, the clamping end of one clamping member 20 extends into the receiving groove 22 of the clamping end of the other clamping member 20, causing the clamping grooves 21 of the two clamping members 20 to hold the material. Since the clamping groove 21 of the thicker clamping member 20 is divided into two, the two clamping members 20 form a three-point positioning clamping method when holding the material, improving the stability of the material clamping and enabling material correction.

[0038] In this embodiment, the lifting seat 2 is equipped with a damper 23 and a limiting member 24. The base 1 is provided with a limiting surface 28. Both the damper 23 and the limiting member 24 are located above the limiting surface 28 and are used to abut against the limiting surface 28. The damper 23 and the limiting member 24 are arranged parallel to each other. During the process of the lifting drive mechanism 3 driving the lifting seat 2 to descend, when the lifting seat 2 descends to its limit position, the damper 23 will abut against the limiting surface 28 to play a damping and buffering role, and the limiting member 24 will abut against the limiting surface 28 to limit the lifting seat 2, ensuring the positional accuracy and stability of the lifting seat 2 during descent.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
