Embodiment 1

[0017] Embodiment 1: as Figures 2 to 4 As shown, this embodiment includes a moving iron core 1 , a return spring 2 , a valve body 3 , a piston rod 5 , a piston 4 , an enameled coil 6 , an iron core shell 7 and an iron core flange 8 .

[0018] The connection relationship is: the outlet chamber 10 is provided with an outlet port 11 connected to the outlet port of the vacuum pump 9, and the inlet chamber is provided with an inlet port 12 connected to the inlet port of the vacuum pump 9. The middle chamber is located in the middle of the air outlet chamber and the air inlet chamber. The middle chamber is provided with a working end interface 13 connected with the air chamber 10 of the cutting machine. There are air holes on the two partitions between the middle chamber and the air outlet chamber and the air inlet chamber. 32, the air inlet cavity end of the valve body 3 also has an air hole 32, and the air outlet cavity end of the valve body 3 has a mounting hole 31; the traction...

Abstract

The invention relates to a conversion valve for a vacuum pump of a cutting machine and belongs to the technical field of machinery. The conversion valve is composed of a valve body, a pulling type electromagnet, a piston rod, pistons and a resetting spring, wherein air pores are arranged on two separating surfaces of a middle cavity, an air outlet cavity and an air inlet cavity; the air pores are also arranged at the air inlet cavity end of the valve body; a mounting hole is arranged at the air outlet cavity end of the valve body; the pulling type electromagnet is mounted at the air outlet cavity end of the valve body; one end of the piston rod is connected with a moveable iron core of the pulling type electromagnet; the piston rod is arranged in three air pores of the valve body in a penetrating form; three pistons are fixed on the piston rod; the three pistons are respectively matched with the three air pores on the valve body; and the resetting spring is arranged in the air outlet cavity. Under the action of the pulling type electromagnet, the piston rod can move and can drive the pistons to control the open / close states of the three air pores, so that the quick releasing and absorbing for materials are realized. The vacuum pump is electrified all the time and is not frequently started and a blowback vacuum pump is not used.

Description

technical field [0001] The invention relates to a steering valve used for a vacuum pump of a cutting machine, which belongs to the technical field of machinery. Background technique [0002] Due to the limitation of cost and site, the current cutting machine cannot make a large effective format. When the cutting length is greater than the length of the machine, an accurate feeding device is needed to ensure the accuracy of the feeding position and make the cutting Graphics can be accurately docked. In order to achieve this function, it is necessary to realize the quick release and fixation of the material. [0003] The structural design of the steering valve used for the vacuum pump of the cutting machine in the prior art is unreasonable, requiring two vacuum pumps, and the vacuum pumps are frequently started during use and have a short service life. Such as figure 1 As shown, there are three ports on the valve A, the inlet port 11' is connected to the inlet port of the a...
