[0002] As the name implies, a double-station cutting machine is a cutting device with two working positions. It is mainly used for the integral die blanking of vacuum thermoformed products, and is also applicable to the cutting of various materials such as packaging and decorations. The double-station cutting machine adopts a four-column double-oil cylinder mechanism, and the fuselage is made of pure steel, with high balance accuracy. The output is balanced and uniform at any position of the workbench surface. At the same time, it is also equipped with a hydraulic circulation system to prevent sundries and dust from circulating into the oil cylinder, ensuring smooth oil delivery and stable pressure. The common double-station cutting machine is open on both sides, occupying a large area. The process of moving back and forth is cumbersome and inconvenient. It is necessary to drag out the internal structure and operate through a series of gear and chain structures. During operation, it is easy to accumulate dust, and subsequent storage is inconvenient. The filtering and heat dissipation effects are poor, affecting the service life of the double-cutting machine. When the cutting knife falls, there may be deviations due to the placement of the material.

[0003] In summary, the prior art has problems such as cumbersome operation during the back-and-forth movement, inconvenient operation, large floor area and difficult subsequent storage, poor filtering and heat dissipation effects affecting the service life of the double-cutting machine, easy dust accumulation and inconvenient subsequent storage, and insufficient accuracy of the cutting knife when it falls.

[0024] Embodiment 1. Referring to Figures 1-4 , in this embodiment, in order to solve the problems existing in the prior art, such as the cumbersome operation during the forward and backward movement, inconvenient operation, large floor area, difficult subsequent storage, poor filtering and heat dissipation effects, which affect the service life of the double-cutting machine, easy dust accumulation and inconvenient subsequent storage, and insufficient accuracy of the cutting knife's downward fall. The present utility model discloses a double-station cutting machine that can move forward and backward, including an upper housing 26, a movable lower housing 21, and a housing 24. In the middle of the upper housing 26 is an oil cylinder 1, and there are guide posts 2 at the four corners respectively. There is an oil cylinder fixing sleeve 5 on the outer side of the bottom of the oil cylinder 1. At the intersection of the guide post 2 and the bottom of the upper housing 26, there is an oil-impregnated bearing bronze bushing 6. The guide post 2 extends downward and is connected to the top of the movable lower housing 21. There are U-shaped shields 3 on both sides of the tops of the upper housing 26 and the movable lower housing 21. The length of the shield 3 is the same as the length of the upper housing 26. The bottom of the upper housing 26 is an impact plate 7, and the bottom of the impact plate 7 is a plastic plate 8, and there are cylinders 4 on both the left and right sides. In the middle of the housing 24 is a pressure plate 25, and there are empty grooves 9 on both the front and rear sides of the pressure plate 25. The movable lower housing 21 is below the empty grooves 9. There are two opposing through ports 28 on both the left and right sides of the movable lower housing 21, and the through ports 28 can pass through the chain 12. On both the left and right sides of the chain 12 are driving sprockets 13, and the driving sprockets 13 are controlled by a power device 14, and the power device 14 is connected to the motor 16. Below the chain 12 inside the housing 24 is a linear guide 22, and there is a movable slide groove 31 on the linear guide 22. Below the movable lower housing 21 is a slide block 29, and the slide block 29 is adapted to the slide groove 31. The motor 16 is on the motor foot plate 20, and the left side of the motor 16 is connected to the flange-mounted oil pump 19 through the flywheel 18, and the left side of the flange-mounted oil pump 19 is an electric control box.

[0025] There are fixed square steel columns 11 at the four corners of the upper part of the housing 24. There are rectangular grooves 10 on the inner side of the fixed square steel columns 11. The grooves 10 are vertical rectangles and are adapted to the cylinders 4. While fans are provided on the front and rear baffles 23 of the housing 24 for heat dissipation, there are also a first filter plate 15 and a second filter plate 17 behind the fans. There is a sound insulation board around the motor 16 and a bottom plate 30 at the bottom. There is a cutting opening at the intersection of the fixed square steel column 11 and the pressing plate 25. Balancing feet 27 are provided at the four corners of the bottom of the housing 24.

[0026] Specific implementation principle: When using the present utility model, the article to be cut can be placed between the fixed square steel columns 11. The cutting knife is installed and fixed between the two cylinders 4. The cylinder 4 is moved into the groove 10 inside the fixed square steel column 11 and fixed. The motor 16 and the oil cylinder 1 are started. The cylinder 4 will not deviate when falling downward in the groove 10. Therefore, the cutting accuracy is more accurate. Moving the lower housing 21 can drive the slider 29 through the rotation of the chain 12 and the driving sprocket 13. The slider 29 is connected to the chute 31. The chute 31 moves on the linear guide 22. Thus, the movement speed of the moving lower housing 21 is faster. The moving lower housing 21 and the upper housing 26 are connected by the guide posts 2 and are thus easier to move. The entire process does not require taking out the internal structure, occupies less floor space and is more convenient to use. In order to prevent overheating of the motor 16 due to sealing, the present utility model adopts the baffle 23, and the baffle 23 not only has heat dissipation holes but also fans and a first filter plate 15 and a second filter plate 17 to ensure the internal air circulation. Balancing feet 27 are provided at the four bottom corners of the housing 24, increasing the contact between the equipment and the ground and enhancing the stability.

[0027] The above are all the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present utility model shall be covered within the protection scope of the present utility model.
