Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to a cutting device. Background Technology

[0002] Silicone parts are products made from silicone rubber, possessing various properties and a wide range of applications. They can be molded through compression molding, extrusion, or injection molding, and feature high temperature resistance, low temperature resistance, ozone resistance, atmospheric aging resistance, and good electrical insulation properties. They are suitable for parts used in high temperature, low temperature, sunlight, atmospheric, and ozone environments, as well as electrical insulation components. Currently, after silicone parts are molded in a mold, they need to be cut out of the mold through processes such as stamping. However, existing stamping devices are not safe enough. Sometimes, due to accidental activation by workers before the mold is fully installed, the stamping device may start, resulting in collisions and damage between the device and the mold. CN217669825U discloses a stamping device for silicone parts, including a base, a drive unit, and a punch. A worktable is provided on the base, and a stamping cavity is formed on the worktable. The drive unit is mounted on the base, and the punch is located at the output end of the drive unit and corresponds to the stamping cavity. The drive unit drives the punch into the stamping cavity to punch the silicone part placed on the worktable. In use, the drive unit drives the punch towards the worktable to punch the silicone part. After stamping, the punch enters the stamping cavity, and the stamped part falls into the cavity. However, this device lacks safety features and has no related protective functions. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a practical and safe pressure cutting device.

[0004] To achieve the above objectives, the present invention provides the following solution: a cutting device, comprising a working platform, multiple first lifting cylinders, multiple supports, and multiple limiting cylinders. Multiple supports are arranged on the working platform, and a first lifting cylinder is mounted on the top of each support. The first lifting cylinder is vertically arranged and connected downwards to a first lifting seat. A top pressure rod is mounted on the bottom of the first lifting seat. Multiple limiting holes are opened on the working platform, and a top pressure rod is aligned downwards with one of the limiting holes. The multiple limiting cylinders are horizontally arranged on the working platform, and each limiting cylinder is connected to a limiting block. The limiting block is used to open or close the limiting hole.

[0005] The beneficial effects of this utility model are as follows: it improves overall safety. The device is equipped with a first lifting cylinder and a stamping die. The first lifting cylinder drives the first lifting seat to move downward. Then, by setting a top pressure rod and a limit cylinder, the limit cylinder drives the limit block to move and close the limit hole. In case of abnormality, detection operation error or emergency stop, the first lifting cylinder can be activated, and the first lifting seat and top pressure rod can move downward. However, since the limit block is at this time, it resists the top pressure rod that is pushing downward, thus preventing the top pressure rod from entering the limit hole. This restricts the first lifting seat from moving downward, improving overall safety. The overall structure is practical and reliable.

[0006] Furthermore, the bracket includes multiple vertical rods and a mounting plate. The multiple vertical rods are arranged vertically and connected upwards to the mounting plate. A first lifting cylinder is installed on the mounting plate, and the multiple vertical rods are slidably connected to the first lifting seat. With the above structure, this invention guides the first lifting seat to move up and down.

[0007] Furthermore, an elastic element is fitted onto the bottom side of one of the vertical rods. With the above structure, this invention allows the first lifting seat to contact the elastic element, reducing the force exerted during the contact between the punch head and the stamping die.

[0008] Furthermore, the top pressure rods are respectively provided on the left and right sides of the bottom of the first lifting seat, and the top pressure rods are arranged vertically.

[0009] Furthermore, the end of the limiting block is formed with a stop, which is used to cover the limiting hole and restrict the top pressure rod from entering the limiting hole.

[0010] Furthermore, a stamping die is fixedly installed on the work platform.

[0011] Furthermore, a punch head is provided at the bottom of the first lifting seat, and the punch head is arranged vertically with the stamping die.

[0012] Furthermore, the bracket is provided with a plurality of second lifting cylinders, which are respectively arranged vertically. The plurality of second lifting cylinders are connected downward to a second lifting seat. A punch head is provided at the bottom of the second lifting seat, and the punch head is arranged vertically with the stamping die.

[0013] Furthermore, the stamping die has multiple positioning holes, and the bottom of the die head has multiple positioning pins and multiple punches. When the die head is aligned with the stamping die, the multiple positioning pins are inserted into the multiple positioning holes one by one. With the above structure, this invention has a positioning function, achieving precise alignment and positioning. The multiple punches can press-cut and punch out the silicone parts from within the stamping die. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0021] See appendix Figure 1 To be continued Figure 4As shown, a pressure cutting device includes a working platform 1, multiple first lifting cylinders 2, multiple supports 3, and multiple limiting cylinders 12. Multiple supports 3 are provided on the working platform 1, and a first lifting cylinder 2 is provided on the top of each support 3. The first lifting cylinder 2 is vertically arranged and is connected downward to a first lifting seat 21. Multiple limiting holes 11 are opened on the working platform 1, and a top pressure rod 23 is aligned downward with a limiting hole 11. Multiple limiting cylinders 12 are respectively arranged horizontally on the working platform 1. The limiting cylinders 12 are connected to limiting blocks 13, which are used to open or close the limiting holes 11.

[0022] In this embodiment, the bracket 3 includes multiple vertical rods 31 and a mounting plate 32. The multiple vertical rods 31 are arranged vertically and are connected to the mounting plate 32 upwards. A first lifting cylinder 2 is provided on the mounting plate 32. The multiple vertical rods 31 are slidably connected to a first lifting seat 21. An elastic element 311 is fitted on the bottom side of one of the vertical rods 31.

[0023] In this embodiment, top pressure rods 23 are respectively provided on the left and right sides of the bottom of the lifting seat 21, and the top pressure rods 23 are arranged vertically.

[0024] In this embodiment, a stop 131 is formed at the end of the limiting block 13. The stop 131 is used to cover the limiting hole 11 and restrict the top pressure rod 23 from entering the limiting hole 11.

[0025] In this embodiment, a stamping die 4 is fixedly installed on the working platform 1; a punch head 22 is installed at the bottom of the first lifting seat 21, and the punch head 22 and the stamping die 4 are arranged vertically; the stamping die 4 has multiple positioning holes 41, and the bottom of the punch head 22 is formed with multiple positioning pins 221 and multiple punches 22. When the punch head 22 is connected to the stamping die 4, the multiple positioning pins 221 are inserted into the multiple positioning holes 41 one by one.

[0026] In this embodiment, the specific pressing and cutting process is as follows: First, the silicone part to be pressed and cut is placed on the stamping die 4. At this time, multiple positioning pins 221 are respectively inserted downwards into multiple positioning holes 41. Then, the two limiting cylinders 12 corresponding to the stamping die 4 are activated. The piston rod of the limiting cylinder 12 retracts to drive the limiting block 13 to move backwards, so that the stop block 131 exits and opens the limiting hole 11. Then, the first lifting cylinder 2 is activated. The piston rod of the first lifting cylinder 2 extends to drive the first lifting seat 21, the punch head 22, and the top pressing rod 23 to move downwards until the punch head 22 docks with the stamping die 4, so that multiple punches 222 enter the stamping die 4 to press and cut the silicone part in the stamping die 4 to cut out multiple silicone parts. The multiple positioning pins 221 are respectively inserted into multiple positioning holes 41, and the top pressing rod 23 enters the limiting hole 11.

[0027] Under normal conditions, when a malfunction occurs, such as an abnormality, a detection operation error, or an emergency stop, the piston rod of the first lifting cylinder 2 extends to drive the first lifting seat 21, the punch head 22, and the top pressing rod 23 to move downwards. However, because the piston rod of the limit cylinder 12 extends to push the limit block 13 forward, the stop block 131 covers the limit hole 11. At this time, when the top pressing rod 23 moves downwards, it will abut against the top pressing stop block 131, preventing the top pressing rod 23 and the first lifting seat 21 from moving downwards. This prevents the punch head 22 from docking with the stamping die 4, thus preventing the punch head 22 from colliding with the stamping die 4 due to misalignment, which could cause damage to the punch head 22 and the stamping die 4 or injury to the workers, thereby improving overall safety. Example

[0028] See appendix Figure 1 To be continued Figure 4 As shown, a cutting device includes a working platform 1, multiple first lifting cylinders 2, multiple supports 3, and multiple limiting cylinders 12. Multiple supports 3 are provided on the working platform 1, and a first lifting cylinder 2 is provided on the top of each support 3. The first lifting cylinder 2 is vertically arranged and is connected downward to a first lifting seat 21. A top pressure rod 23 is provided at the bottom of the first lifting seat 21. Multiple limiting holes 11 are opened on the working platform 1. A top pressure rod 23 is aligned downward with a limiting hole 11. Multiple limiting cylinders 12 are respectively arranged horizontally on the working platform 1. The limiting cylinders 12 are connected to limiting blocks 13, which are used to open or close the limiting holes 11.

[0029] In this embodiment, the bracket 3 includes multiple vertical rods 31 and a mounting plate 32. The multiple vertical rods 31 are arranged vertically and are connected to the mounting plate 32 upwards. A first lifting cylinder 2 is provided on the mounting plate 32. The multiple vertical rods 31 are slidably connected to a first lifting seat 21. An elastic element 311 is fitted on the bottom side of one of the vertical rods 31.

[0030] In this embodiment, top pressure rods 23 are respectively provided on the left and right sides of the bottom of the first lifting seat 21, and the top pressure rods 23 are arranged vertically.

[0031] In this embodiment, a stop 131 is formed at the end of the limiting block 13. The stop 131 is used to cover the limiting hole 11 and restrict the top pressure rod 23 from entering the limiting hole 11.

[0032] In this embodiment, a stamping die 4 is fixedly installed on the working platform 1; a plurality of second lifting cylinders 5 are installed on the bracket 3, and the plurality of second lifting cylinders 5 are respectively vertically arranged. The plurality of second lifting cylinders 5 are connected downward to a second lifting seat 51. The second lifting seat 51 slides on a plurality of vertical rods 31. A punch head 22 is provided at the bottom of the second lifting seat 51. The punch head 22 and the stamping die 4 are arranged vertically. A plurality of positioning holes 41 are opened on the stamping die 4. A plurality of positioning pins 221 and a plurality of punches 222 are formed at the bottom of the punch head 22. When the punch head 22 is connected to the stamping die 4, the plurality of positioning pins 221 are inserted into the plurality of positioning holes 41 one by one.

[0033] In this embodiment, the specific pressing and cutting process is as follows: First, the silicone part to be pressed and cut is placed on the stamping die 4. At this time, multiple positioning pins 221 correspond downwards to multiple positioning holes 41. Then, the two limiting cylinders 12 corresponding to the stamping die 4 are activated. The piston rod of the limiting cylinder 12 retracts, thereby driving the limiting block 13 to move backward, so that the stop block 131 exits and opens the limiting hole 11. Then, the first lifting cylinder 2 is activated. The piston rod of the first lifting cylinder 2 extends, thereby driving the first lifting seat 21 and the top pressing rod 23 to move downwards. The first lifting seat 21 presses down on the stamping die 4, and multiple positioning pins 221 are inserted into multiple positioning holes 41 one by one. The top pressing rod 23 enters the limiting hole 11. Finally, the second lifting cylinder 5 is activated, and the piston rod of the second lifting cylinder 5 extends to drive the second lifting seat 51 and the punch head 22 to move down until the punch head 22 passes through the first lifting seat 21 and docks with the stamping die 4, so that multiple punches 222 enter the stamping die 4 to press and cut the silicone parts in the stamping die 4 to cut out multiple silicone parts.

[0034] Under normal conditions, when a malfunction occurs, such as an abnormality, a detection operation error, or an emergency stop, the piston rod of the first lifting cylinder 2 extends to drive the first lifting seat 21 and the top pressure rod 23 to move downward. However, because the piston rod of the limit cylinder 12 extends to push the limit block 13 forward, the stop block 131 covers the limit hole 11. At this time, when the top pressure rod 23 moves downward, it will abut against the top pressure stop block 131, preventing the top pressure rod 23 and the first lifting seat 21 from moving downward. This prevents the first lifting seat 21 from pressing down on the stamping die 4, thus preventing the first lifting seat 21 from colliding with the stamping die 4 due to misalignment, which could damage the stamping die 4 or cause injury to the workers, thereby improving overall safety.

[0035] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any person skilled in the art can make more possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, all equivalent changes made based on the concept of this utility model without departing from the content of the technical solution of this utility model should be covered within the protection scope of this utility model.
