Description

Technical Field

[0001] The invention relates to the field of cutting equipment, in particular to a spherical cutting machine. Background Art

[0002] At present, the production of lenses on the market generally uses cutting machines, such as the attached Fig.10 As shown, it is a simplified structural diagram of a feeding and retracting cutting device in an existing spherical cutting machine. The position of the cutting material is manually measured by a measuring ruler 402, and then the manual clamping device 401 is adjusted to the corresponding position and fixed by manual operation. The cutting device is composed of a driving motor connected to a rotating shaft equipped with a cutting blade through a belt 403. The bottom of the cutting device is connected to the equipment base through a rotating joint 404, and a handle 406 is provided at one end of the bottom of the cutting device. A weight block 405 is connected below the handle 406. Such equipment often brings the following problems: 1. Positioning of the processing material, positioning of the cutting tool, and loading during the cutting process. 1. The advance and retreat of materials and tools are mostly done manually, which is time-consuming, labor-intensive and has poor precision. 2. The cutting blade is driven by belt. Since there is oil cooling on the top of the cutting blade, the belt is easily attached with oil. After being soaked, the belt will become loose and slip, causing the cutting speed to slow down, affecting the yield rate. The belt needs to be replaced frequently, increasing costs. 3. The bottom of the cutting device is supported by a rotating joint. The weight difference on both sides of the rotating joint is very large, so it needs to be operated by hand. In order to reduce the operating burden of people, it is necessary to add a counterweight on the lighter end to achieve a balance of weight on both ends of the fulcrum. This arrangement has poor accuracy and greatly reduces the yield rate. In addition to the above attachments Fig.10 In addition to the problems with the cutting machines on display, most cutting machines also have the following problems: the powder dispersion and coolant fumes generated during the processing are harmful to the human body; most of the original cutting machines can only meet the straight saw cutting requirements, and then obtain the required special-shaped products after the grinding process, such as the production of tocle lenses; the original cutting machines often require more than one operator for each cutting machine, with high labor costs, and the equipment operation is cumbersome and the degree of automation is low.

[0035] like Fig.10 As shown, it is a simplified structural diagram of a feeding and retracting cutting device in an existing spherical cutting machine. The position of the cutting material is manually measured by a measuring ruler 402, and then the manual clamping device 401 is adjusted to the corresponding position and fixed by manual operation. The cutting device is composed of a driving motor connected to a rotating shaft equipped with a cutting blade through a belt 403. The bottom of the cutting device is connected to the equipment base through a rotating joint 404, and a handle 406 is provided at one end of the bottom of the cutting device, and a weight block 405 is connected below the handle 406.

[0036] Compared with the existing cutting machine, the feeding and retracting device of the present invention adopts a direct-connected motor to drive the transmission screw to rotate and then drive the clamping device on the screw to advance and retreat, and uses a linear slide rod and a linear bearing to ensure the movement direction and stability of the clamping device; a first motor and a reducer are used to control the second motor and the cutting tool through the second transmission shaft, and rotate at a certain speed in the horizontal direction around the axis of the second transmission shaft. At the same time, the second motor drives the blade to rotate through the rotating shaft. When cutting the processed material, the blade rotates around the axis of the second transmission shaft while rotating itself under the action of the second motor to achieve the purpose of cutting the processed material; during the cutting process, the oil smoke generated by oil cooling is discharged to the outside through the exhaust fan, which does not affect human health, and the waste generated automatically falls into the waste box at the bottom, and the waste box is detachable for easy cleaning.

The touch screen is electrically connected to other electric control components of the present invention through the control box, such as lighting, direct motor, first motor and second motor, etc. The touch screen is mainly divided into two units. The first unit is: inputting raw material size, blade cutting thickness, cutting thickness, total number of cutting knives and displaying the number of completed cutting knives and the number of remaining knives; the second unit is: displaying the blade cutting speed, the second transmission shaft rotation speed and the forward and backward speed of the feeding and retracting device. In addition, the touch screen is also provided with control keys: raw material feed touch key, raw material retract touch key, blade feed touch key, blade retract touch key, exhaust fan switch, lighting switch touch key and oil circuit switch touch key, and the functions of these keys can also be controlled by the corresponding controlled switches under the touch screen. These keys are both on the touch screen and manually operated, which not only provides convenience of operation, but also meets emergency safety performance. If the touch screen cannot operate the above control keys, it can be realized by manual mode, and the control panel is also provided with an emergency stop button, which greatly improves the safety of the equipment.

[0038] A specific embodiment of the present invention: processing natural crystal lens

[0039] First, prepare the crystal raw materials, process the Tianren crystal into a certain shape, and install it on the clamping piece of the clamping device;

[0040] Second, select a curved cutting blade with a radius of 13.1 mm and an arc of 400 degrees, and install it on the threaded section of the rotating shaft;

[0041] Third, close the mobile access door and set relevant parameters through the human-machine interface touch screen that has been filled with the processing program, such as material size, length, width, blade cutting thickness, cutting thickness, total number of cutting knives, blade cutting speed, second transmission shaft rotation speed and forward and backward speed of the feeding and retracting device;

[0042] Fourth, operate the control keys on the touch screen in sequence: first turn on the lighting switch, turn on the exhaust fan switch, turn on the control box cooling fan switch, turn on the oil pump switch, and then start the feeding and withdrawing device and the cutting device to process the natural crystal stone raw materials;

[0043] Fifth, after the cutting step is completed, the oil pump is turned off, the feeding and retracting device and the cutting device return to the initial position and stop working, the operator takes out the finished product, replaces the new crystal stone raw material, and repeats the above steps.

[0044] After using the equipment of the present invention, one person can operate multiple machines at the same time, while one machine previously required one or more operators to operate the machine. The automation of the equipment is improved, labor is saved, and the cutting accuracy of the product is improved, which greatly improves the production efficiency and the yield of the product.
