Description

Technical Field

[0001] The utility model relates to the technical field of mechanical shock absorption, and in particular to a shock absorption device for a nail making machine. Background Art

[0002] Steel nails, as a type of fastener, are widely used in various aspects such as industry, agriculture, construction, and civil use. They are mainly used to fix objects with small axial separation force and small radial shear force. They have the characteristics of simple processing, easy use, and rapid nailing. Steel nails need to be made using a nail making machine during the production process. The nail making machine uses a series of processes to process raw materials such as steel wire or scrap steel bars into steel nails that meet the standards.

[0003] Existing devices have some disadvantages during use. For example, when making steel nails, the nail making machine will generate vibration and impact force. The existing nail making machine cannot reduce the vibration and impact force. The vibration of the nail making machine not only affects the stability of the equipment, but also causes the fasteners inside the equipment to loosen, thereby affecting the accuracy and life of the equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a shock absorbing device for a nail making machine, so as to solve the problem that the existing nail making machine cannot reduce vibration and impact force.

[0005] The utility model provides the following technical solution: a shock-absorbing device for a nail-making machine, comprising a nail-making machine body, sliding blocks are provided at the four corners of the lower end surface of the nail-making machine body, supporting feet are provided below the four sliding blocks, and sliding grooves are provided on the upper end surfaces of the four supporting feet. The four sliding blocks are slidably connected to the corresponding supporting feet through the corresponding sliding grooves, the milling end surface of the nail-making machine is fixedly connected to a hydraulic pump, a connecting component for connecting to the nail-making machine body is provided on the sliding block, and a shock-absorbing component is provided on the supporting feet.

[0006] In the above solution, vibration and impact force are unavoidable physical phenomena during the operation of the nail making machine. Through the intervention of the shock-absorbing component, these forces are effectively absorbed and dispersed, thereby extending the service life of the equipment.

[0007] As a preferred embodiment of the above technical solution, the connecting assembly includes connecting plates fixedly connected to the upper end faces of the four sliding blocks respectively, and the upper end faces of the four connecting plates are fixedly connected to shock-absorbing rubber pads. Fastening screws are provided at the four corners below the connecting plates, and the top ends of the four fastening screws vertically penetrate the connecting plates and the shock-absorbing rubber pads and are slidably connected to the connecting plates and the shock-absorbing rubber pads. The sliding block is connected to the nail making machine body through the fastening screws.

[0008] In the above solution, tightening screws makes the installation and adjustment of the connecting components more convenient, and the addition of shock-absorbing rubber pads further enhances the shock-absorbing effect. The rubber material has good elasticity and damping properties, and can effectively absorb and disperse vibration energy, thereby reducing the impact on the nail making machine body and the surrounding environment.

[0009] As a preferred embodiment of the above technical solution, the shock-absorbing assembly includes sliding rods fixedly connected to the four corners of the bottom wall of the four sliding grooves, four sliding grooves are vertically opened at the four corners of the lower end surfaces of the four sliding blocks, and the four sliding blocks are slidingly connected to the corresponding four sliding rods through the four sliding grooves. The lower end surfaces of the four sliding blocks are each provided with an installation groove, and springs are vertically arranged in the four installation grooves, and the two ends of the four springs are respectively fixedly connected to the corresponding top wall of the installation groove and the corresponding bottom wall of the sliding groove.

[0010] In the above scheme, the four sliding rods are fixedly connected to the four corners of the bottom wall of the four sliding grooves, providing stable support and guidance for the sliding block. The spring can undergo elastic deformation during vibration, absorbing and dissipating vibration energy. This buffering effect helps to reduce impact and damage to the equipment and extend the service life of the equipment.

[0011] As a preferred embodiment of the above technical solution, the shock absorbing assembly also includes sealing tubes respectively arranged on the inner sides of the four springs, the top ends of the four sealing tubes are fixedly connected to the top walls of the corresponding four installation grooves, and sealing cavities are opened inside the four sealing tubes. Piston blocks are slidably connected in the four sealing cavities, and the bottom ends of the four piston blocks are fixedly connected to piston rods, and the bottom ends of the four piston rods are fixedly connected to the bottom walls of the corresponding sliding grooves.

[0012] In the above solution, the sealed cavity opened in the sealed tube can be filled with a shock-absorbing liquid (such as hydraulic oil). When the piston block slides in the sealed cavity, the liquid generates a damping force, further consuming vibration energy.

[0013] As a preferred embodiment of the above technical solution, sealing blocks are provided under the four sealing tubes, and connecting holes are opened on the four sealing blocks. The four sealing blocks are slidably connected to the outer sides of the corresponding piston rods through the corresponding connecting holes, and the upper end faces of the four sealing blocks are fixedly connected to the lower end faces of the corresponding sealing tubes, and annular grooves are opened in the inner sides of the four connecting holes, and sealing gaskets are fixedly connected in the four annular grooves.

[0014] In the above solution, the sealing gasket enhances the sealing effect. Its soft and wear-resistant properties can fit closely to the surface of the piston rod, and it can maintain good sealing performance even under high pressure or long-term use.

[0015] As a preferred embodiment of the above technical solution, one side of the top of the four sealing tubes is fixedly connected to a pipe, the ends of the four pipes away from the sealing tubes pass through the corresponding sliding blocks, and the ends of the four pipes away from the sealing tubes are fixedly connected to the hydraulic pump.

[0016] In the above scheme, the shock-absorbing performance of the shock-absorbing component can be adjusted in real time by injecting or discharging shock-absorbing liquid (such as hydraulic oil) into the sealed tube through a hydraulic pump. When the equipment is subjected to vibrations of different frequencies and amplitudes, the hydraulic pump can adjust the pressure and flow of the shock-absorbing liquid as needed, thereby providing a more precise shock-absorbing effect.

[0017] As a preferred embodiment of the above technical solution, two piston holes are formed through the piston block, and the two piston holes are symmetrically arranged.

[0018] In the above scheme, the two symmetrically arranged piston holes enable the shock-absorbing liquid (such as hydraulic oil) to flow more evenly when the piston block moves up and down. This uniform fluid flow helps to reduce the turbulence and eddy currents of the liquid in the sealed cavity, thereby reducing energy loss and improving shock absorption efficiency.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] In the utility model, when the nail making machine generates vibration, the sliding block moves up and down along the sliding rod in the sliding groove. This design can initially absorb and disperse the vibration energy. When the sliding block moves, the piston block will also move in the sealed chamber. The movement of the piston block changes the volume of the liquid in the sealed chamber, thereby triggering the flow of the liquid. This design enables the shock absorbing component to have better response speed and shock absorption effect when responding to fast or high-frequency vibrations. The hydraulic pump provides a stable liquid pressure to the sealed chamber through the pipeline. This design enables the liquid to produce a damping effect during the flow process, further absorbing and dispersing the vibration energy. The enhancement of the damping effect helps to improve the overall performance of the shock absorbing component, so that the equipment can still maintain good stability under long-term operation. By effectively absorbing and dispersing vibration energy, the shock absorbing component can reduce the failure rate of the equipment due to vibration, which helps to reduce the maintenance cost of the equipment, improve production efficiency, and thus extend the service life of the equipment.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Example

[0030] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a shock absorbing device for a nail making machine, comprising a nail making machine body 10, wherein sliding blocks 11 are provided at the four corners of the lower end surface of the nail making machine body 10, and supporting feet 12 are provided below the four sliding blocks 11, and sliding grooves 13 are provided on the upper end surfaces of the four supporting feet 12. The four sliding blocks 11 are slidably connected to the corresponding supporting feet 12 through the corresponding sliding grooves 13, and the milling end surface of the nail making machine is fixedly connected to a hydraulic pump 14, and a connecting component 2 for connecting the nail making machine body 10 is provided on the sliding block 11, and a shock absorbing component 3 is provided on the supporting foot 12. During specific use, the sliding block 11 is connected to the nail making machine body 10 through the connecting component 2. When the nail making machine is working, certain vibrations and impact forces will be generated. These vibrations and impact forces will be transmitted to the shock absorbing component 3 on the supporting foot 12 through the sliding block 11. The shock absorbing component 3 absorbs and disperses these vibrations and impact forces, thereby reducing the impact on the nail making machine body 10 and the surrounding environment.

[0031] As an implementation method in this embodiment, Figure 1 and Figure 2As shown, the connecting assembly 2 includes connecting plates 201 respectively fixedly connected to the upper end surfaces of the four sliding blocks 11, and the upper end surfaces of the four connecting plates 201 are fixedly connected with shock-absorbing rubber pads 202. Fastening screws 203 are provided at the four corners below the connecting plate 201. The top ends of the four fastening screws 203 vertically penetrate the connecting plate 201 and the shock-absorbing rubber pads 202 and are slidably connected to the connecting plate 201 and the shock-absorbing rubber pads 202. The sliding block 11 is connected to the nail-making machine body 10 through the fastening screws 203. During specific use, the fastening screws 203 are vertically penetrated through the connecting plate 201 and the shock-absorbing rubber pads 202, and the fastening screws 203 are tightened using appropriate tools until they are firmly connected to the corresponding positions of the nail-making machine body 10.

[0032] As an implementation method in this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6As shown, the shock absorbing assembly 3 includes sliding rods 305 fixedly connected to the four corners of the bottom wall of the four sliding grooves 13, four sliding grooves 306 are vertically opened at the four corners of the lower end surfaces of the four sliding blocks 11, and the four sliding blocks 11 are slidably connected to the corresponding four sliding rods 305 through the four sliding grooves 306. The lower end surfaces of the four sliding blocks 11 are each provided with a mounting groove 307, and springs 308 are vertically arranged in the four mounting grooves 307, and the two ends of the four springs 308 are respectively fixedly connected to the corresponding inner top wall of the mounting groove 307 and the corresponding inner bottom wall of the sliding groove 13. The shock absorbing assembly 3 also includes The sealing tubes 301 are respectively arranged on the inner sides of the four springs 308, the top ends of the four sealing tubes 301 are fixedly connected to the top walls of the corresponding four mounting grooves 307, the four sealing tubes 301 are provided with sealing cavities 302, the four sealing cavities 302 are slidably connected with piston blocks 303, the bottom ends of the four piston blocks 303 are fixedly connected to piston rods 304, the bottom ends of the four piston rods 304 are fixedly connected to the bottom walls of the corresponding sliding grooves 13, the top sides of the four sealing tubes 301 are fixedly connected to pipes 50, and the ends of the four pipes 50 away from the sealing tubes 301 pass through the corresponding sliding blocks 1 1, and one end of the four pipes 50 away from the sealing tube 301 is fixedly connected to the hydraulic pump 14, and two piston holes 60 are formed through the piston block 303, and the two piston holes 60 are symmetrically arranged. During specific use, when the nail making machine starts working, it will generate a certain amount of vibration and impact force. Under the action of the vibration, the sliding block 11 will move up and down in the sliding groove 306 along the sliding rod 305. This movement can initially absorb and disperse part of the vibration energy. As the sliding block 11 moves, the spring 308 will be compressed or stretched. The elasticity of the spring 308 can absorb and store the vibration energy and release it after the vibration. To reduce the impact on the nail making machine body 10, when the sliding block 11 moves, the piston block 303 will also move in the sealed chamber 302. The movement of the piston block 303 will change the volume of the liquid in the sealed chamber 302, thereby triggering the flow of the liquid. The piston hole 60 allows the liquid to pass more smoothly when the piston block 303 moves, reducing the flow resistance of the liquid. This makes the shock absorbing assembly 3 have better response speed and shock absorption effect when responding to fast or high-frequency vibrations. The hydraulic pump 14 provides a stable liquid pressure to the sealed chamber 302 through the pipeline 50, so that the liquid produces a damping effect during the flow process, further absorbing and dispersing vibration energy.

[0033] As an implementation method in this embodiment, Figure 4 and Figure 5As shown, a sealing block 40 is provided below the four sealing tubes 301, and a connecting hole 41 is opened on the four sealing blocks 40. The four sealing blocks 40 are slidably connected to the outer side of the corresponding piston rod 304 through the corresponding connecting holes, and the upper end faces of the four sealing blocks 40 are fixedly connected to the lower end faces of the corresponding sealing tubes 301. An annular groove 42 is opened in an annular manner on the inner side of the four connecting holes, and a sealing gasket 43 is fixedly connected to the four annular grooves 42. During specific use, when the nail making machine vibrates, the vibration energy is transmitted to the shock absorber through the sliding block 11. On component 3, the sliding block 11 moves up and down in the sliding groove 306 through the sliding rod 305, and at the same time compresses or stretches the spring 308 to absorb part of the vibration energy. As the sliding block 11 moves, the piston rod 304 also moves up and down in the sealing chamber 302. The sealing block 40 is tightly fitted on the outside of the piston rod 304 through the connecting hole 41 thereon. When the piston rod 304 moves in the sealing chamber 302, the sealing gasket 43 is in close contact with the surface of the piston rod 304, forming an effective seal to ensure that the liquid will not leak out from the gap between the piston rod 304 and the sealing block 40.

[0034] Working principle: Use the fastening screw 203 to vertically penetrate the connecting plate 201 and the shock-absorbing rubber pad 202, and use an appropriate tool to tighten the fastening screw 203 until the fastening screw 203 is firmly connected to the corresponding position of the nail making machine body 10. When the nail making machine starts working, it will generate a certain amount of vibration and impact force. The sliding block 11 moves up and down under the guidance of the sliding rod 305 and the sliding groove 306, initially absorbing and dispersing part of the vibration energy. As the sliding block 11 moves, the spring 308 will be compressed or stretched, further absorbing and storing the vibration energy. The elasticity of the spring 308 enables it to release the stored energy after the vibration, thereby reducing the impact on the nail making machine body 10 The piston block 303 moves up and down in the sealing chamber 302 as the sliding block 11 moves, changing the volume of the liquid in the sealing chamber 302. The flow of the liquid through the piston hole 60 is smoother, reducing the flow resistance. The hydraulic pump 14 provides a stable liquid pressure to the sealing chamber 302 through the pipeline 50, so that the liquid produces a damping effect during the flow process, further absorbing and dispersing the vibration energy. When the piston rod 304 moves in the sealing chamber 302, the sealing gasket 43 is in close contact with the surface of the piston rod 304 to form an effective seal, which ensures that the liquid will not leak out from the gap between the piston rod 304 and the sealing block 40, thereby ensuring the normal operation of the shock absorbing assembly 3.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
