Description

Technical Field

[0001] The invention belongs to the technical field of cutting equipment, and in particular relates to a steel formwork floor slab cutting machine. Background Art

[0002] Steel formwork floors are widely used in construction. With the continuous expansion of the scale of construction projects and the improvement of construction efficiency and quality requirements, it is necessary to quickly and accurately cut steel formwork floors to meet the construction needs of different sizes and shapes. For example, in prefabricated buildings, prefabricated steel formwork floors need to be cut and adjusted according to the actual situation on site to ensure that they can be accurately installed, which puts high demands on the accuracy and efficiency of the cutting equipment.

[0003] China Invention discloses a prefabricated floor cutting machine (publication number: CN 219325389 U), comprising a mobile frame, a mobile frame and a mobile plate, a cutting motor is mounted on the mobile plate, a slider fixedly connected to the upper end of the mobile frame is slidably connected to the upper end of the mobile frame, a first screw threadedly connected to the mobile plate is rotatably connected to the upper end of the slider, two universal wheels are mounted on both side walls of the mobile frame, a clamping mechanism for clamping the prefabricated floor is provided on the side wall of the mobile frame, the clamping mechanism comprises two fixed plates fixedly connected to the side wall of the mobile frame, and the side wall of the fixed plate is rotatably connected to the second screw. The present invention is provided with a clamping mechanism, which can fix the mobile frame near the prefabricated floor, and the mobile frame will not move during cutting, thereby improving the stability of the device during cutting.

[0004] The Chinese invention discloses a construction steel form cutting device (publication number: CN 214979530 U), comprising a cutting table, a mounting plate fixedly connected to the cutting table through a plurality of support rods, a cutting mechanism for cutting the construction steel form body is arranged on the mounting plate, the cutting mechanism comprises a cylinder fixedly connected to the mounting plate, a knife holder is fixedly connected to the telescopic end of the cylinder, a cutting knife is arranged on the knife holder, a feeding mechanism for conveying the construction steel form body is arranged on the cutting table, a mounting frame is arranged on the cutting table, a power mechanism for providing the power required by the feeding mechanism is arranged on the mounting frame, a limiting plate is fixedly connected to the cutting table, a mounting groove is arranged on the mounting plate, and a discharging mechanism for pushing the construction steel form body after cutting away from the cutting table is arranged in the mounting groove. The invention has a reasonable structure, can automatically feed and unload the construction steel form that needs to be cut, is easy to operate, and can improve the cutting efficiency.

[0005] Although the above patent uses a first screw connected by a threaded connection of a movable plate to clamp the clamping mechanism of the prefabricated floor slab, there are certain risks when the movable plates on both sides of the device are used for clamping operations during actual use. Since the clamping force of the movable plate is difficult to control, if the clamping force is too large, it may cause damage to the surface of the clamped object, causing scratches, deformation or even breakage of the object, thereby affecting its normal function and service life. Construction steel molds are used to realize automatic feeding and unloading processes. However, due to the lack of positioning and guiding mechanisms, during the feeding stage, the material is easy to deviate from the preset path, resulting in deviations in the docking with the steel mold, which not only reduces the feeding efficiency, but may also cause the material to collide with the edge of the steel mold, causing appearance damage and affecting the subsequent processing quality. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are only for the purpose of enabling the reader to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0025] like Figure 1-6 As shown, a steel membrane floor cutting machine includes a cam 13 fixedly installed on one end of a driving rod 8, a hole is provided on the top of one side surface of the cam 13, a tension spring 14 is fixedly installed in the hole on the top of one side of the cam 13, one end of the tension spring 14 is fixedly installed on the hinged arm 3, a nut 15 is fixedly installed in a positioning hole 101 on one side of the base 1, a fixed connecting plate 16 is fixedly installed on one end of the nut 15, shaft grooves 17 are provided on both sides of one side surface of the fixed connecting plate 16, one end of the fixed connecting plate 16 is placed on the other side end surface of the base 1, a cutting frame is fixedly installed on the lower surface of the base by bolts, and a cutting knife is movably constructed on the upper surface of the cutting frame.

[0026] The base 1 can be installed at any position of the equipment according to the actual structure and operation requirements of the floor cutting equipment. A step groove 102 is provided on one side of the base 1, and the limiting top 2 can be slidably connected to the surface of the step groove 102 to ensure the stability of the connection. One end face of the limiting top 2 is built as a hammering surface. When the steel mold cutting operation is performed, it is only necessary to place the steel mold floor stably between the cutting table 5 and the limiting top 2 to complete the cutting process efficiently and accurately.

[0027] Secondly, the motor converts electrical energy into mechanical energy. Through the belt drive, the motor shaft is connected to the shaft of the cutting knife 19 through the belt. The friction force of the belt is used to transmit power. Under the action of power, the cutting knife 19 cuts the fixed steel formwork floor at a certain speed and in a certain way.

[0028] In order to further ensure the stability of the steel mold during the cutting process, a fixed connecting plate 16 is provided. The fixed connecting plate 16 is installed in the positioning hole 101 to facilitate the adaptation of steel molds of different thicknesses. The operator can flexibly select the corresponding positioning hole 101 according to the actual thickness of the steel mold, and place the nut 15 therein to make it firmly abut the steel mold, thereby achieving reliable fixation of the steel mold. The fixed connecting plate 16 and the base 1 cooperate with each other to form a stable triangular structure. This structure not only provides stable support for the entire cutting operation and effectively disperses stress, but also greatly improves the stability and reliability of the equipment during operation, ensuring that each cutting operation can be completed accurately and smoothly.

[0029] Positioning holes 101 are provided on both sides of one side surface of the base 1, a step groove 102 is provided on one side surface of the base 1, a limiting top 2 is slidably clamped in the step groove 102 on one side of the base 1, a side plate 201 is fixedly installed on one side of the limiting top 2 by bolts, a hammering surface is provided on the front end of one side of the limiting top 2, a hinged arm 3 is movably connected to the surface of the side plate 201 of the limiting top 2 through a rotating shaft, and a shaft wheel 4 is movably connected to the side of the hinged arm 3 away from the side plate 201 through a rotating shaft, a cutting platform 5 is slidably overlapped on the side of the step groove 102 away from the limiting top 2, a rectangular groove is provided on one side of the upper surface of the cutting platform 5, and a threaded rod 6 is movably connected to the rectangular groove of the cutting platform 5 through a bearing. The outer arc surface of the threaded rod 6 is sleeved with an arc arm A7, and a through hole 701 is opened at the top of the outer arc surface of the arc arm A7. One side of the arc arm A7 is threadedly connected to the outer arc surface of the threaded rod 6 through the through hole 701. A driving rod 8 is fixedly installed on the lower surface of the arc arm A7, and a round wheel 9 is fixedly installed at one end of the driving rod 8. The outer arc surface of the round wheel 9 extends to the outside of the arc arm A7. An arc arm B10 is fixedly installed on the side of the driving rod 8 away from the arc arm A7. There are two arc arms B10. A shaft rod 11 is connected between the bottom ends of one side of the two arc arms B10. A reference wheel 12 is sleeved in the middle of the outer arc surface of the shaft rod 11, and the outer arc surface of the reference wheel 12 is movably overlapped with the shaft wheel 4.

[0030] In the dynamic operation process of steel template cutting, due to the difference in diameter of the steel template, when the steel template passes through the area between the limiting top 2 and the cutting platform 5, the limiting top 2 will change in the step groove 102 (such as Figure 1 As shown in the figure, it slides flexibly from left to right to make room for the adaptation and ensure that the steel template can be smoothly put into place. After the entire steel template is stably placed on the cutting frame 18, thanks to the elastic restoring force of the tension spring 14, the limiting top 2 first approaches one side of the steel template autonomously. Along with the gradual displacement of the limiting top 2, the side plate 201 connected thereto will also produce a linkage change synchronously. This change will be pulled by the axis on one side of the articulated arm 3. Along the moving path of one side of the side plate 201, one end of the articulated arm 3 begins to naturally sink vertically downward under the action of the deadweight of the shaft wheel 4 and gravity.

[0031] At the same time, due to the downward displacement of the shaft wheel 4 connected to the hinge wall 3, the shaft wheel 4 is overlapped on the reference wheel 12 on one side of the arc arm B10. It is particularly worth noting that in the process of the hinge arm 3 moving downward, the tension spring 14 connected to one side will exert force synchronously to pull the cam 13 connected to the other end toward the hinge arm 3, thereby ensuring that the shaft wheel 4 is always firmly placed above the reference wheel 12. On this basis, under the downward pressure of gravity, the arc arm B10 uses its lower end as a moving fulcrum to move in the opposite direction. The arc arm A7 and the arc arm B10 are combined to form a semi-crescent structure under the connection of the round wheel 9. In this way, when the bottom end is subjected to force, it will take the round wheel 9 on the driving rod 8 as the rotation center and move in a curved trajectory under the drive of the downward pressure. Specifically, the bottom end moves smoothly from left to right, and the top end moves coordinatedly from right to left. This linkage prompts the top arc arm A7 to drive the threaded rod 6 to slide forward.

[0032] In addition, the tension spring 14 arranged on the cam 13 serves as a connecting link to connect the cam 13 with the articulated arm 3. When the articulated arm 3 undergoes the above-mentioned action transformation, the tension spring 14, by virtue of its own elastic characteristics, pulls the cam 13, so that its top moves downward, thereby driving the cutting table 5 on one side to gradually approach the other side of the steel mold. Finally, by limiting the top 2 and the cutting table 5 to simultaneously apply force to connect from both sides of the steel mold, a stable clamping force is used to lay a solid foundation for the subsequent steel mold cutting process, effectively ensuring that the steel mold can be cut strictly according to the predetermined standard, and effectively improving the overall quality and efficiency of the production operation.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
