Description

Technical Field

[0001] The utility model belongs to the technical field of processing of microwave absorbing foam boards, and particularly relates to a cutting machine for processing microwave absorbing foam boards. Background Technique

[0002] With the development of modern science and technology, the impact of electromagnetic wave radiation on the environment is increasing day by day. At airports, flights are often delayed because electromagnetic wave interference prevents them from taking off; in hospitals, mobile phones often interfere with the normal operation of various electronic diagnostic instruments. Therefore, controlling electromagnetic pollution and finding a material that can resist and weaken electromagnetic wave radiation - microwave absorbing material - has become a major topic in materials science. A microwave absorbing material refers to a type of material that can absorb or significantly weaken the electromagnetic wave energy received on its surface, thereby reducing electromagnetic wave interference. In engineering applications, in addition to requiring the microwave absorbing material to have a high absorption rate of electromagnetic waves in a relatively wide frequency band, it is also required to have properties such as light weight, temperature resistance, humidity resistance, and corrosion resistance.

[0003] With the research and application of microwave absorbing foam boards, various processing procedures are required during the processing of microwave absorbing foam boards, including forming, cutting, etc. A cutting machine is needed during cutting. When the existing cutting machine cuts, the fixing effect on the product is poor. The fixing method is a relatively clamping type fixing on both sides, while the other two sides of the product are not clamped. In this way, the phenomenon of the product running off track and being misaligned easily occurs. When cutting a product that has run off track and is misaligned, the operation accuracy will be reduced. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cutting machine for processing microwave absorbing foam boards, so as to solve the problem that the existing cutting machine has a poor fixing effect on the product during cutting. The fixing method is a relatively clamping type fixing on both sides, while the other two sides of the product are not clamped. In this way, the phenomenon of the product running off track and being misaligned easily occurs. When cutting a product that has run off track and is misaligned, the operation accuracy will be reduced, which is mentioned in the above background technique.

[0005] To achieve the above object, the utility model provides the following technical solution: A cutting machine for processing and using an absorbing foam board, comprising a base. Mounting bolts are penetrated through four corner positions of the base. One side of the upper surface of the base is fixedly installed with a fixed clamping plate, and the other side of the upper surface of the base is movably provided with a movable clamping plate. Two rotating shafts are rotatably installed on the inner wall of the fixed clamping plate. A handle is fixedly installed at the end of one of the rotating shafts. A bidirectional screw rod is fixedly installed between the two rotating shafts. Threaded sleeves are threadedly installed on the threaded outer surfaces of two sections of the bidirectional screw rod. A connecting rod is fixedly installed on the side surface of the threaded sleeve. The connecting rod passes through a channel opened on the side surface of the fixed clamping plate and extends out of the fixed clamping plate and is fixedly installed with a side clamping plate. A frame is slidably installed on the base. A sliding plate is slidably installed on the frame. A lead screw is threadedly installed on the sliding plate. A knob is fixedly installed at the top end of the lead screw. An installation plate is rotatably installed at the bottom end of the lead screw.

[0006] By adopting the above solution, through the use of the fixed clamping plate, the movable clamping plate and the side clamping plate, the relatively arranged fixed clamping plate and the movable clamping plate realize the clamping and fixing of the opposite side surfaces. The rotation of the bidirectional screw rod can realize the relative movement of the two side clamping plates, realize the clamping and fixing of the other opposite side surfaces, and further realize the four-way clamping and fixing of the product, effectively avoiding the phenomenon of the product running off and misaligning during the cutting operation, effectively ensuring the cutting operation accuracy, and having a simple structure and convenient operation and adjustment.

[0007] As a preferred implementation manner, a guide bar 2 is fixedly installed on the inner wall of the fixed clamping plate, and a guide groove 2 for cooperating with the guide bar 2 is opened on the side surface of the threaded sleeve.

A first spring is fixedly installed between the limiting disc and the operation plate.

[0012] With the above scheme, the fixed guide rod can guide the operation plate to improve the smoothness of the movement of the operation plate. When the locking rod disengages from the locking groove, the first spring deforms, and at this time, the frame is unlocked and can be slid to adjust the position. Therefore, after adjusting the position, the elastic force of the first spring can be used to drive the locking rod to quickly insert into the locking groove, improving the convenience of the locking operation.

The cooperation of the guide bar one 9 and the guide groove one can support the movement of the frame 10 and improve the movement stability.

[0031] A locking rod 21 is slidably installed on the frame 10 at a position opposite to the guide groove one. A plurality of locking grooves for inserting the locking rod 21 are opened on the side surface of the guide bar one 9. An operation plate 20 is fixedly installed at one end of the locking rod 21. A fixed guide rod 17 is slidably installed on the operation plate 20. One end of the fixed guide rod 17 is fixed to the side surface of the frame 10.

The cooperation of the trapezoidal block 26 and the trapezoidal groove can ensure the smooth movement of the movable clamping plate 15. The setting of the third spring 25 can provide a reset force. The cooperation of the extrusion screw 27 and the push-pull plate can squeeze and lock the position of the movable clamping plate 15.

[0035] When in use, first unscrew the extrusion screw 27, pull the push-pull plate. The push-pull plate drives the movable clamping plate 15 to move in a direction away from the fixed clamping plate 3 through the trapezoidal block 26. At the same time, the third spring 25 deforms. Then place the product to be cut on the surface of the base 1 in contact with the fixed clamping plate 3. After placing it, release the push-pull plate. At this time, the elasticity of the third spring 25 will drive the movable clamping plate 15 to reset. After the movable clamping plate 15 moves to contact the product, screw in the extrusion screw 27. At this time, the fixed clamping plate 3 and the movable clamping plate 15 clamp the opposite sides of the product. Then rotate the handle to drive the rotating shaft 4 to drive the bidirectional screw 5 to rotate, thereby driving the two threaded sleeves 6 to move relative to each other, and then driving the connecting rod 7 to drive the side clamping plate 8 to move, using the side clamping plate 8 to clamp the other opposite sides of the product, thereby completing the four-way clamping of the product in the front, back, left, and right directions. Then adjust the position of the cutter 14 according to the cutting needs. When adjusting, pull the operation plate 20 to drive the locking rod 21 out of the locking groove. At this time, the frame 10 is unlocked and the first spring 19 deforms. Hold the frame 10 and slide it through the first guide bar 9. After sliding, release the operation plate 20, and use the elasticity of the first spring 19 to drive the locking rod 21 to reset and insert into the locking groove to complete the locking. Then start the cutter 14, use the rotation of the lead screw 12 to drive the mounting plate 13 to drive the cutter 14 to move downward, and drive the sliding plate 11 to move horizontally through the push rod 22 to complete the cutting.
