Description

Technical Field

[0001] The utility model belongs to the field of mechanical technology, in particular to a balancing mechanism of a precision four-column hydraulic cutting machine. Background Art

[0002] The full name of the four-column cutting machine is hydraulic precision four-column cutting machine, which is widely used in the cutting and processing procedures of handbags, luggage, shoes, leather goods, silk flowers, foam, blister, plush toys, sports goods, automotive products, EVA and other industries. What we want to talk about here is a new type of precision four-column hydraulic cutting machine.

[0003] Existing hydraulic cutting machines usually use guide columns for guidance. When the device is cutting some harder or thicker materials, the moving plate that fixes the tool will shake slightly during cutting, causing the lifting plate moving on the outer surface of the guide column to be locked, increasing the frequency of damage to the transmission parts on the inner wall of the device and reducing the service life of the parts inside the device. Utility Model Content

[0004] The purpose of the utility model is to provide a balancing mechanism for a precision four-column hydraulic cutting machine. By setting a balancing component, the lifting plate is made more stable and will not shake during the movement, which solves the problem that the existing hydraulic cutting machine usually uses guide columns for correction. When the device cuts some harder or thicker materials, the moving plate that fixes the tool will shake slightly during cutting, causing the lifting plate moving on the outer surface of the guide column to be locked, thereby increasing the frequency of damage to the transmission parts on the inner wall of the device and reducing the service life of the parts inside the device.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0009] Furthermore, a fixed rod is fixedly connected to the bottom of the second moving block, a spring is fixedly connected to the top of the fixed rod, and the top of the spring is fixedly connected to the top of the inner wall of the second groove. By setting the spring, the tension generated when the spring is deformed and the force generated when the lifting plate shakes are offset.

[0010] Furthermore, a telescopic rod is fixedly connected to the bottom output end of the hydraulic cylinder, a lifting plate is fixedly connected to the bottom of the telescopic rod, a square groove is provided on the top of the lifting plate, the inner wall of the square groove is slidably connected to the outer surface of the sliding block, and moving blocks 1 are fixedly connected to the four corners of the lifting plate, and circular grooves 2 are provided inside the four moving blocks 1, and the inner wall of the circular grooves 2 is slidably connected to the outer surface of the guide column.

[0011] Furthermore, there are two limit assemblies, which are symmetrically arranged with the hydraulic cylinder as the center. The parts included in the two limit assemblies are the same. The limit assemblies include a threaded rod. By setting the limit assemblies, the tool is more stable when cutting the material. A square groove is opened on the top of the cutting table. The inner wall of the square groove is rotatably connected to the outer surface of the threaded rod.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model sets a balancing component, specifically, the sliding block is driven to move when the lifting plate moves downward, so that the rotating rod can rotate as the lifting plate moves downward.

[0015] 2. The utility model sets a limit assembly. Specifically, when the device needs to cut some materials with harder materials and larger areas, the two handles are rotated clockwise to drive the two limit blocks to move, so that the inner walls of the slide grooves opened inside the two limit blocks contact the protrusions on both sides of the lifting plate, thereby improving the stability of the lifting plate when moving, making the tool more stable when cutting the material, and improving the practicality of the device.

The top of the spring 227 is fixedly connected to the top of the inner wall of the groove 2. By setting the balancing component 22, specifically, the lifting plate 13 moves downward, which will drive the sliding block 221 to move, so that the rotating rod 222 can rotate with the lifting plate 13 moving downward. At the same time, the lifting plate 13 moves downward, which will cause the spring 227 to deform and generate an upward pulling force, so that the lowering tool will not shake when cutting the material, thereby reducing the frequency of damage to the transmission parts and improving the service life of the parts inside the device.

The force generated by the left and right two springs 227 can effectively reduce the shaking of the tool when cutting the material, so that the lifting plate The tool at the bottom of 13 will not tilt and get stuck with the four guide pillars 3 during the cutting process, which reduces the frequency of damage to the transmission parts and increases the service life of the parts inside the device. When the device needs to cut some materials with harder materials and larger areas, the two handles 332 are rotated clockwise.

During the rotation of the two threaded rods 331, the two moving blocks three 333 are driven to move toward each other. During the movement of the two moving blocks three 333, the two limit blocks 334 are driven to move at the same time, so that the inner walls of the slide grooves opened on the inner walls of the two limit blocks 334 are in contact with the protrusions on both sides of the lifting plate 13, thereby improving the stability of the lifting plate 13 when moving, making the tool more stable when cutting materials, and improving the practicality of the device.
