Description

Technical Field

[0001] This utility model relates to the field of hydraulic cutting, specifically to a multi-functional hydraulic cutting device. Background Technology

[0002] Multifunctional hydraulic cutting devices belong to the technical field of hardware material cutting and processing. They are widely used in the production process of various hardware products and are mainly used to cut and shape hardware materials. They are important equipment for material processing in the hardware manufacturing process.

[0003] Traditional metal material cutting often uses cam-type cutting machines, whose force transmission method can easily lead to insufficient precision in material cutting. This results in products with low dimensional accuracy, weak load-bearing capacity, high residual stress, and poor surface quality, making it difficult to effectively guarantee the mechanical properties of the products. At the same time, the drive structure and sensing components of existing cutting devices are not well coordinated, often making it difficult to achieve fully automatic sensing operation. This requires a lot of manual intervention to adjust the material length, and the equipment has poor durability and reliability, resulting in a short service life. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned defects and provide a multi-functional hydraulic press cutting device. It uses a liquid pump as the force transmission medium to replace the traditional cam machine cutting machine, so that the material is cut against the punch under the action of the force transmission medium. This solves the technical problem that the existing force transmission method is prone to insufficient precision in material cutting, resulting in low dimensional accuracy, weak load-bearing capacity, high residual stress and poor surface quality of the produced products, and the mechanical properties of the products are difficult to be effectively guaranteed.

[0005] The objective of this utility model is achieved through the following means:

[0006] A multi-functional hydraulic cutting device includes a cutting machine section, which comprises a hydraulic telescopic slide rail, a punch rod, a crank arm adjusting nut, a slide rail retaining ring, a slide seat adjusting screw, and an auxiliary mandrel holder. A hydraulic assembly is added to the outside of the cutting machine section. A connecting arm is added to the telescopic end of the hydraulic assembly. A fixed seat is connected to the surface of the hydraulic assembly. A connecting ring plate is added above the connecting arm. A cam and a drive motor are respectively added to the front and back of the connecting ring plate. The drive motor is coaxially connected to the cam. An automatic induction switch is added to the outside of the connecting ring plate.

[0007] Before starting work, adjust the two nuts separately using the crank arm adjusting nut to change the length of the slide rail index seat and adjust it to a suitable extension; use the slide seat adjusting screw to fix and adjust the slide seat using its thread characteristics to adjust the angle when the mold feeds; when installing and adjusting the hydraulic press, the slide rail retaining ring fixes the slide rail to the front side to prevent the crank arm from suddenly pulling back and causing danger.

[0008] After the device is started, the drive motor rotates and drives the cam to rotate 360 ​​degrees to the highest position. At this time, the cam pushes the automatic sensor switch. With the help of the cam's reciprocating motion and speed, the appropriate material length is preset.

[0009] Once the preset is complete, the hydraulic telescopic slide rail begins to work. It is equipped with an auxiliary mandrel holder and performs cutting operations on the hardware material by reciprocating in a straight line on the slide rail.

[0010] During the cutting process, the punch rod works with the hydraulic press to force the slide rail to retract when necessary to prevent collisions.

[0011] Throughout the process, the hydraulic components provide power, and their telescopic ends drive the movement of related components such as the connecting ring plate through the connecting arm. The fixed seat plays a role in fixing the hydraulic components, ensuring the stable operation of the device.

[0012] Furthermore, a fixing plate is installed on the upper surface and the rear end of the lower surface of the fixing base, and the front side of the fixing plate is evenly provided with connection holes.

[0013] Fixing plates are installed on the rear ends of the upper and lower surfaces of the fixing base, and connection holes are evenly machined on the front side of the fixing plates.

[0014] Furthermore, the fixing base consists of an upper connecting base and a lower connecting base. A fixing plate is installed on the lower surface of the upper connecting base, and a fixing hole is opened on the upper surface of the lower connecting base. The fixing plate and the fixing hole are connected by insertion.

[0015] The mounting base is divided into an upper mounting base and a lower mounting base. A fixing plate is installed on the lower surface of the upper mounting base, and a fixing hole is made on the upper surface of the lower mounting base. During installation, the fixing plate is inserted into the fixing hole to complete the combination of the upper and lower mounting bases.

[0016] Furthermore, each of the lower connecting seats has a limiting groove on its front side, and a limiting slide plate is slidably connected inside the limiting groove. A connecting rod is added between adjacent upper and lower connecting seats.

[0017] A limiting groove is made on the front of the lower connecting seat, and the limiting slide plate is slidably connected inside the limiting groove. A connecting rod is installed between the adjacent upper and lower connecting seats.

[0018] Furthermore, the front of the fixing plate is provided with a insertion groove, and the lower surface of the fixing plate and the bottom of the inner cavity of the insertion groove are both designed with a slope.

[0019] A insertion groove is machined on the front of the fixed plate, and the lower surface of the fixed plate and the bottom of the inner cavity of the insertion groove are designed as bevels.

[0020] Furthermore, the front of the lower connector is connected to an outer connecting handle, which is inserted into the limiting slide plate. An insertion bevel is installed at the inner end of the outer connecting handle, and a compression spring is added between the outer connecting handle and the insertion bevel. The two ends of the compression spring are respectively in contact with the inner wall of the lower connector and the surface of the insertion bevel. The inner end of the insertion bevel extends inward through the outer wall of the lower connector, and the upper part of the inner end of the insertion bevel is designed with a bevel, which corresponds to the position of the fixing hole and the insertion slot.

[0021] Connect the outer connecting handle to the front of the lower connecting seat, so that the outer connecting handle is inserted into the limiting slide plate. Install the insertion bevel head at the inner end of the outer connecting handle, and install a compression spring between the outer connecting handle and the insertion bevel head. Ensure that the two ends of the compression spring are in contact with the inner wall of the lower connecting seat and the surface of the insertion bevel head, respectively. At the same time, let the inner end of the insertion bevel head extend inward through the outer wall of the lower connecting seat, and let the upper bevel of its inner end correspond to the position of the fixed insertion hole and the insertion slot.

[0022] The beneficial effects of this utility model are: by using a liquid pump as the force transmission medium to replace the traditional cam machine cutting machine, the material is cut by sticking to the punch under the action of the force transmission medium, which helps to improve the cutting accuracy, and the produced products have high dimensional accuracy, strong load-bearing capacity, low residual stress and good surface quality, thus significantly improving the mechanical properties of the products.

[0023] The cam on the connecting ring plate is coaxially connected to the drive motor. Combined with the automatic induction switch on the outside, the drive motor rotates to drive the cam to rotate 360 ​​degrees to the highest position. The cam then pushes the automatic induction switch. With the help of the cam's reciprocating motion and speed, a suitable material length is preset to achieve fully automatic sensing operation, which enhances the durability and reliability of the equipment and extends its service life.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The multi-functional hydraulic press cutting device specifically implemented includes a cutting machine part 1, which includes a hydraulic telescopic slide rail, a punch rod, a crank arm adjusting nut, a slide rail retaining ring, a slide seat adjusting screw, and an auxiliary mandrel holder. A hydraulic component 2 is added to the outside of the cutting machine part 1. A connecting arm 3 is added to the telescopic end of the hydraulic component 2. A fixed seat 4 is connected to the surface of the hydraulic component 2. A connecting ring plate 5 is added above the connecting arm 3. A cam 6 and a drive motor 7 are added to the front and back of the connecting ring plate 5, respectively. The drive motor 7 is coaxially connected to the cam 6. An automatic induction switch 8 is added to the outside of the connecting ring plate 5.

[0033] Before starting work, adjust the two nuts separately using the crank arm adjusting nut to change the length of the slide rail index seat and adjust it to a suitable extension; use the slide seat adjusting screw to fix and adjust the slide seat using its thread characteristics to adjust the angle when the mold feeds; when installing and adjusting the hydraulic press, the slide rail retaining ring fixes the slide rail to the front side to prevent the crank arm from suddenly pulling back and causing danger.

[0034] After the device is started, the drive motor 7 rotates and drives the cam 6 to rotate 360 ​​degrees to the highest position. At this time, the cam 6 pushes the automatic sensing switch 8. With the help of the reciprocating motion and speed of the cam 6, the appropriate material length is preset.

[0035] Once the preset is complete, the hydraulic telescopic slide rail begins to work. It is equipped with an auxiliary mandrel holder, which is fixed on the slide rail and performs cutting operations on the hardware material in a linear reciprocating motion on the slide rail.

[0036] During the cutting process, the punch rod works with the hydraulic press to force the slide rail to retract when necessary to prevent collisions.

[0037] Throughout the process, the hydraulic component 2 provides power, and its telescopic end drives the connecting ring plate 5 and other related components to move through the connecting arm 3. The fixed seat 4 plays a role in fixing the hydraulic component 2 to ensure stable operation of the device.

[0038] By using hydraulic component 2 as the force transmission medium to replace the cam machine cutting machine, the material is brought into contact with the punch under the action of the force transmission medium to achieve the cutting of hardware materials. It has versatility, thereby reducing costs and shortening the production cycle.

[0039] like Figure 2 As shown, a fixing plate 9 is installed on the upper surface and the rear end of the lower surface of the fixing base 4, and the front side of the fixing plate 9 is evenly provided with connection holes.

[0040] Fixing plates 9 are installed on the rear ends of the upper and lower surfaces of the fixing base 4, and connecting holes are uniformly machined on the front side of the fixing plates 9. By setting fixing plates 9 with connecting holes on the rear ends of the upper and lower surfaces of the fixing base 4, it is convenient to connect and fix the fixing base 4 with other external structures, thereby improving the convenience and stability of the installation of the fixing base 4.

[0041] like Figure 4 As shown, the fixing base 4 consists of an upper connecting base 10 and a lower connecting base 11. A fixing plate 13 is installed on the lower surface of the upper connecting base 10, and a fixing hole 15 is opened on the upper surface of the lower connecting base 11. The fixing plate 13 and the fixing hole 15 are connected by insertion.

[0042] The fixing base 4 is divided into an upper connecting base 10 and a lower connecting base 11. A fixing plate 13 is installed on the lower surface of the upper connecting base 10, and a fixing hole 15 is opened on the upper surface of the lower connecting base 11. During installation, the fixing plate 13 is inserted into the fixing hole 15 to complete the combination of the upper connecting base 10 and the lower connecting base 11. The fixing base 4 adopts a combination structure in which the upper connecting base 10 and the lower connecting base 11 are connected by the fixing plate 13 and the fixing hole 15, which facilitates the disassembly and assembly of the fixing base 4 and is conducive to the later maintenance and replacement of parts.

[0043] like Figure 5 As shown, each of the lower connecting seats 11 has a limiting groove 20 on its front side, and each limiting groove 20 is slidably connected to a limiting slide plate 19. A connecting rod 12 is added between the adjacent upper connecting seats 10 and the lower connecting seats 11.

[0044] A limiting groove 20 is provided on the front of the lower connecting seat 11, and the limiting slide plate 19 is slidably connected inside the limiting groove 20. A connecting rod 12 is added between the adjacent upper connecting seat 10 and lower connecting seat 11. The sliding connection design of the limiting groove 20 and the limiting slide plate 19 can play a certain role in limiting and guiding the position of related components. At the same time, the addition of the connecting rod 12 can enhance the firmness of the connection between the upper connecting seats 10 and the lower connecting seat 11, and improve the stability of the overall structure.

[0045] The front of the fixed insert plate 13 is provided with a plug groove 14, and the lower surface of the fixed insert plate 13 and the bottom of the inner cavity of the plug groove 14 are both designed with a slope.

[0046] A insertion groove 14 is machined on the front side of the fixed insertion plate 13, and the lower surface of the fixed insertion plate 13 and the bottom of the inner cavity of the insertion groove 14 are designed as bevels. The insertion groove 14 on the fixed insertion plate 13 can cooperate with other components to achieve more precise connection, and the bevel design can play a guiding role in the process of the fixed insertion plate 13 being inserted into the fixed insertion hole 15, making the insertion process smoother and reducing installation resistance.

[0047] like Figure 6 As shown, the front of the lower connecting seat 11 is connected to an outer connecting handle 18. The outer connecting handle 18 is inserted into the limiting slide plate 19. An insertion bevel 16 is installed at the inner end of the outer connecting handle 18. A compression spring 17 is added between the outer connecting handle 18 and the insertion bevel 16. The two ends of the compression spring 17 are respectively in contact with the inner wall of the lower connecting seat 11 and the surface of the insertion bevel 16. The inner end of the insertion bevel 16 extends inward through the outer wall of the lower connecting seat 11. The upper part of the inner end of the insertion bevel 16 is designed with a bevel, which corresponds to the position of the fixing hole 15 and the insertion groove 14.

[0048] Connect the outer connecting handle 18 to the front of the lower connecting seat 11, so that the outer connecting handle 18 is inserted into the limiting slide plate 19. Install the insertion bevel head 16 at the inner end of the outer connecting handle 18, and install a compression spring 17 between the outer connecting handle 18 and the insertion bevel head 16. Ensure that both ends of the compression spring 17 are in contact with the inner wall of the lower connecting seat 11 and the surface of the insertion bevel head 16, respectively. At the same time, allow the inner end of the insertion bevel head 16 to extend inward through the outer wall of the lower connecting seat 11, and ensure that the upper part of its inner end... The inclined surface of the outer connecting handle 18, the insertion inclined head 16 and the compression spring 17 are positioned corresponding to the fixed insertion hole 15 and the insertion groove 14. The design of the outer connecting handle 18, the insertion inclined head 16 and the compression spring 17 can make the insertion inclined head 16 fit tightly with the fixed insertion hole 15 and the insertion groove 14 by using the elastic force of the compression spring 17, thereby enhancing the stability of the connection between the upper connecting seat 10 and the lower connecting seat 11. The inclined surface design of the upper part of the inner end of the insertion inclined head 16 facilitates its fit with the structure on the fixed insert plate 13, thereby improving the smoothness of the connection.

[0049] The usage process of the multi-functional hydraulic cutting device in this embodiment is as follows: After the device is started, the drive motor 7 rotates and drives the cam 6 to rotate 360 ​​degrees to the highest position. At this time, the cam 6 pushes the automatic induction switch 8. With the help of the reciprocating motion and speed of the cam 6, a suitable material length is preset.

[0050] Once the preset is complete, the hydraulic telescopic slide rail of the cutting machine part 1 starts to work. It is equipped with an auxiliary mandrel holder, which is fixed on the slide rail and performs the cutting operation of hardware materials in a linear reciprocating motion on the slide rail.

[0051] During the cutting process, the punch rod of the cutting machine part 1, in conjunction with the hydraulic press, forces the slide rail to retract when necessary to prevent collisions. Throughout the process, the hydraulic component 2 provides power, and its telescopic end drives the connecting ring plate 5 and other related components to move through the connecting arm 3. The fixed seat 4 fixes the hydraulic component 2 to ensure stable operation of the device. The hydraulic component 2 is used as the force transmission medium to replace the cam machine cutting machine, so that the material is pressed against the punch under the action of the force transmission medium to achieve the cutting of hardware materials.
