Description

Technical Field

[0001] The present invention relates to the technical field of cutting machines, in particular to a rocker-arm type leather cutting device. Background Art

[0002] A rocker-type cutting machine is a type of cutting machine used in industrial production to punch out various flexible materials. It is used in industry to shape and cut one or more layers of leather, plastic, canvas, nylon, fiber, paperboard, and various synthetic materials. Existing rocker-type cutting machines require a corresponding cutting mold to complete the shaping and cutting of leather into a specified shape.

[0003] During the daily production of the rocker-arm cutting machine, workers are required to manually place and adjust the cutting mold. Although such manual operation is convenient and fast, it is prone to positional offset during the placement process. At the same time, due to the elasticity of leather, the cutting mold is prone to overall skew during the placement process. These will make it impossible to complete the cutting work as required, resulting in leather waste.

One end of the two threaded blocks 10 away from the two threaded grooves 9 passes through the fixing port 8. The two threaded blocks 10 are slidably connected to be set in the fixing port 8. The ends of the two threaded blocks 10 away from the two threaded grooves 9 are fixedly connected with a fixing plate 11. The two fixing plates 11 are both fitted with the mounting frame 5. A mounting groove 12 is provided on the upper end surface of the two mounting seats 7; two mounting grooves 12 are slidably connected with mounting columns 13, and mounting holes 14 are provided on the inner walls of the lower ends of the two mounting grooves 12.

The limiting block 27 is fixedly connected to the control column 25. In this way, with the help of the cooperation of the limiting block 27 and the limiting groove 26, the control column 25 can be effectively prevented from being pushed out of the control hole 24 by the positioning block 29, and the control column 25 can be prevented from being excessively pressed and inserted into the positioning groove 28 to hinder the movement work. A plurality of positioning grooves 28 are provided on the side wall of the mobile column 23 close to the control hole 24. There are fixed grooves 28 in the plurality of positioning grooves 28. The positioning block 29, multiple positioning blocks 29 are matched with the control hole 24, and a positioning spring 30 is fixedly connected to the side wall of the positioning block 29 away from the control hole 24.

With the help of the auxiliary grooves 39 and the auxiliary blocks 40, the positioning block 29 can be effectively avoided because of the positioning spring 3 0 elastic force and excessively disengage from the positioning groove 28, which greatly ensures the integrity of the device. The two moving columns 23 are each provided with a connecting component at one end close to each other, and a cutting die 31 is provided between the two connecting components. The connecting component includes a connecting groove 32 provided on the side wall of the moving column 23, and a connecting disk 33 is fixedly connected to the inner wall of the connecting groove 32. A connecting magnetic block 34 is also slidably connected in the connecting groove 32. The connecting magnetic block 34 and the connecting magnetic disk 33 are mutually attracted.

A lifting spring 38 is fixedly connected to one side wall of the lifting block 37. The end of the lifting spring 38 away from the lifting block 37 is fixedly connected to the inner wall of the lifting slot 36. The cutting die 31 is fixedly connected to the two lifting blocks 37. This allows the cutting die 31 to move stably and accurately while maintaining a perpendicular position to the leather. This ensures stable and accurate cutting, avoiding the problem of leather waste.

[0021] When in use, first carry out the corresponding installation work, that is, slide the corresponding mounting seat 7 into the mounting opening 6 to the specified position as needed, and then rotate the threaded block 10 in the threaded groove 9 to make the fixing plate 11 fit against the mounting frame 5, so that the fixing work of the mounting seat 7 can be completed by means of extrusion friction. Then, the two mounting columns 13 on the control frame 17 can be inserted into the corresponding mounting grooves 12 respectively to complete the preliminary placement of the control frame 17. During this process, the mounting screw 15 will pass through the corresponding mounting hole 14, and then the gasket 41 can be sleeved on the mounting screw 15, and the fixing work is completed by means of the threaded connection of the mounting nut 16 and the mounting screw 15. At this time, the staff can select the appropriate movable column 23 and the corresponding cutting according to the needs of this leather cutting. Cutting mold 31, after selection is completed, first pass the moving column 23 through the corresponding moving port 22. During this process, the staff can completely block the control hole 24 by pressing the control column 25, so that the positioning block 29 cannot be inserted into the control hole 24, and then the installation work can be completed smoothly. Then the staff can insert the connecting magnetic blocks 34 at both ends of the cutting mold 31 into the corresponding connecting grooves 32 respectively, and fix them together with the connecting disk 33, so that the corresponding installation and fixing work is successfully completed. The positioning blocks 29 on different moving columns 23 have different spacings, which can cooperate to complete different spacing adjustment work of the cutting mold 31, and different cutting molds 31 can cooperate with the staff to complete leather cutting work of different shapes, which greatly meets the use needs of the staff.

[0022] Then, when working, the staff can control the working assembly 3 and the rotating hydraulic assembly 2 through the operating rod 4, so that the working assembly 3 descends and squeezes the cutting die 31 to cut the leather. In this process, the lifting block 37 is first in a higher state due to the elastic force of the lifting spring 38, so that the cutting die 31 is initially in a high position and does not touch the leather. This can avoid the cutting die 31 being placed directly on the leather, and then due to the elasticity of the leather, the placement of the cutting die 31 will be skewed. This greatly ensures the smooth completion of the cutting work and avoids the problem of damage to the cutting die 31 and waste of leather. Then, during the downward pressing process, the lifting block 37 can slide in the lifting groove 36, so the descending cutting work of the cutting die 31 can be completed smoothly. When a cutting work is completed, the staff can push and pull the two movable columns 23. Before pushing and pulling, it is necessary to press the control column 25 first. , so that the control column 25 slides in the control hole 24 and pushes out the positioning block 29 inserted into the control hole 24, so that the movable column 23 loses its restriction and can smoothly complete the movement work. When pushing and pulling, the staff can loosen the control column 25. In this way, when the movable column 23 moves to the specified position, the other positioning block 29 can be inserted into the control hole 24 again under the elastic force of the corresponding positioning spring 30 to complete the clamping limit work, and then the movable column 23 can drive the cutting mold 31 to complete the position adjustment work of the specified spacing, so that the leather can be accurately cut, avoiding the occurrence of waste. At the same time, the staff can also rotate the two threaded rods 21 at the same time, and then cooperate with the threaded connection of the threaded rod 21 and the threaded hole 20 to adjust the position of the control seat 19 longitudinally, so that the longitudinal position of the cutting mold 31 can be adjusted, and then the leather on the base 1 can be cut more comprehensively.
