Description

Technical Field

[0001] The invention belongs to the field of steel plate processing equipment and relates to an automatic steel plate cutting production line. Background Art

[0002] Steel plate cutting is common in industrial production in industries such as mechanical processing and mold manufacturing. The steel plate cutting process is not only related to the accuracy of subsequent processing but also to the processing cost of steel plate cutting companies. Therefore, steel plate cutting is very important.

[0003] Among the common equipment currently available, fully automated steel plate cutting machine equipment has high metal content but is relatively expensive. For many equipment that are still running well, if a new production line is directly replaced, it will greatly increase production costs for many companies, which is unrealistic. In addition, the production volume of steel plates in some companies has not yet reached the level of practical large-scale automated equipment. Rash use will cause waste of equipment and is not suitable for the development of the company. Currently common cutting machines have the following problems.

[0004] It is difficult for the commonly used steel plate cutting machines to achieve continuous loading. During the cutting process, the machine has to stop for loading, which affects the processing efficiency. Moreover, the loading speed is slow. Most of them use motor screw lifting, and can load about 3 steel plates per minute. The speed is slow, which affects the cutting efficiency.

[0005] The commonly used steel plate cutting machines at present often encounter the situation where the last steel plate falls off during the pushing and cutting process. The last steel plate cannot fall onto the splicing belt due to its small width and other reasons. In addition, when cutting specifications with smaller widths, material falling will also occur in many cases.

[0006] Currently, the commonly used steel plate cutting and splicing machines are mostly set up in conjunction with cutting machines. After the splicing is completed, they are uniformly transferred. The structure is relatively complex and not conducive to subsequent operations. The transfer process after splicing also takes up a lot of manpower, which increases labor intensity.

[0022] Compared with the prior art, the present invention has the following advantages and positive effects.

[0023] 1. The feeding car of the present invention is provided with at least two feeding plates, which realizes continuous feeding and ensures the continuity of steel plate cutting. Moreover, the whole structure is simple and stable. The lifting adopts a driving cylinder, which is simpler and easier to control than the traditional motor screw lifting structure. The feeding rhythm of this structure can reach 6 plates per minute, which is twice as fast as the traditional feeding speed, greatly improving the work efficiency.

[0024] 2. The steel plate is adsorbed by a suction cup in the lifting assembly, which uses the negative pressure principle and has a simple structure. In addition, a guide rod slidably connected to the fixed frame is provided on the lifting frame to improve the up and down movement accuracy of the lifting frame and improve the structural stability at the same time;

[0025] 3. The transverse moving assembly is driven by a gear tooth structure, which has a simple structure, low cost, small space occupation, and independent setting. It is also suitable for the transformation of existing equipment. The sensors and limit plates set on the support frame ensure the movement accuracy of the transverse moving plate and further improve the stability of the structure.

[0026] 4. In the transverse movement assembly, the position of the motor plate is adjusted by adjusting the screw. The adjusting screw is threadedly connected to the adjusting frame. The position of the adjusting screw is changed by rotating the adjusting screw relative to the adjusting block. The adjusting screw can support the motor plate for adjustment and movement, making the adjustment of the motor plate more convenient and accurate, and the adjustment is more labor-saving, which improves the assembly efficiency;

[0027] 5. The guide components are set to guide both sides of the steel plate to ensure the positioning accuracy of the steel plate in the transmission direction, ensure the straightness of the cutting, and improve the cutting accuracy. In addition, the push component set in this structure adopts a linear slide module with high precision and can accurately feed the material, simplifying the control degree. The practicality of the entire structure is higher, the stability is better, and the reliability and cutting accuracy of the equipment are improved;

[0028] 6. The guide assembly adopts a bilaterally symmetrical structure, and the width adjustment is achieved through linkage adjustment by the nut block and the lead screw, which makes the adjustment more precise, ensuring that the steel plate is symmetrically arranged relative to the center line of the push rack in the transmission direction, improving the positioning accuracy of the steel plate, and the guide assembly contacts the steel plate through rollers, adopts a line-surface foundation, reduces the friction coefficient, is conducive to reducing the noise of the structure operation, prolongs the service life of the structure, and has higher stability;

[0029] 7. The push component is driven by a servo motor, which can record the position of the adapter at any time. Through the recording and feedback of the position, the push position and push rhythm of the steel plate can be accurately determined, ensuring the consistency of the cutting width, improving the cutting quality, and simplifying the control program;

[0030] 8. An anti-drop component is set on the cutting component. The lifting cylinder first descends, and then the push cylinder moves. The push plate drives the lifting cylinder and the push rod to move forward, pushing the last cut steel plate to the material receiving belt, and then the material receiving belt is transmitted to the next process, which can prevent the last steel plate from falling and has better stability.

[0031] 9. The present invention sets the lift and the unloading car as a separate structure, which is convenient for timely replacement of the specifications of the lift, and is suitable for unloading and transportation of steel plates of different specifications, with a wider range of applications. In addition, the positions of the side baffles and the rear baffles are adjustable, which has a guiding effect on baffles of various specifications, thereby improving the versatility of the unloading car and reducing the application cost of the enterprise. The unloading car is separated from the cutting part, which is convenient for the transportation of materials and reduces the labor intensity.

[0032] 10. The first guide surface and the second guide surface are provided, which is equivalent to expanding the unloading range of the steel plate, guiding the steel plate during unloading, and facilitating the accurate positioning of the steel plate;

[0033] 11. Set the positioning plate and positioning hole. When receiving the material, the positioning rod passes through the adjustment hole on the positioning plate and is inserted into the positioning hole to ensure the stability in the receiving state. When it needs to be transferred, the positioning rod can be removed, which improves the versatility of the unloading car. BRIEF DESCRIPTION OF THE DRAWINGS

[0100] Preferably, the drive assembly 36 includes a plurality of adjustment plates 361, and the adjustment plate 361 acts as a nut and moves relative to the unloading trolley 32 through a threaded lever 362 cooperating therewith.

The detachable structure of the unloading trolley 32 and the unloading guide rail 31 makes one unloading trolley 32 suitable for receiving steel plates of various specifications, which improves the versatility of the unloading trolley 32 and saves the cost of the enterprise.

[0102] In actual use, during the loading process, multiple steel plates are first placed on the loading plate 121 of one of the loading carts 12, and then the driving motor 126 drives the driving roller to slide relative to the loading guide rail 11. When the loading plate 121 reaches the loading station, one of the sensor sheets 124 corresponds to the sensor switch, and sends a signal that the loading cart 12 is in place. Then the lifting assembly 13 moves, and the output shaft of the driving cylinder 134 extends to drive the lifting frame 132 to move downward. At this time, under the action of the magnetic spreader 122, the uppermost steel plate is separated from the lower steel plate. After the lifting frame 132 moves downward, the suction cup 133 contacts the steel plate. Under the action of vacuum, multiple suction cups 133 adsorb the steel plate, and then the output shaft of the driving cylinder 134 retracts, driving the steel plate to move upward. During the up and down movement of the lifting frame 132, the guide rod 135 plays a guiding role to ensure the accuracy and stability of the up and down movement. After the lifting frame 132 drives the steel plate to rise into place, the transverse movement assembly 14 starts Movement, the transverse plate 141 under the action of the transverse motor 143, the gear 1431 moves relative to the rack, driving the transverse plate 141 to move, and then driving the lifting component 13 component fixed to the transverse plate 141, to transfer the steel plate from the loading plate 121 to the loading conveyor belt, completing the loading action of the steel plate. While the steel plates on this loading plate 121 are continuously loaded, the other loading plate 121 continues to load. When the steel plates on this loading plate 121 are loaded, after the last steel plate is grabbed, the other loading plate 121 full of steel plates arrives at the loading position, ensuring the smooth grabbing and loading of the suction cup 133 next time, realizing continuous loading, ensuring the continuity of cutting of the steel plate 40, and the whole structure is simple and stable. The lifting adopts the driving cylinder 134, which is simpler and simpler to control than the traditional motor screw lifting structure, and the rhythm is faster. The loading rhythm of this structure can reach 6 plates per minute, which is twice as fast as the traditional loading speed, greatly improving the work efficiency.

[0103] During the cutting process, after installation, the relative distance between the two movable plates 2133 is adjusted according to the specifications of the steel plate and the formation of the guide cylinder 2132, and the adjustment is made by rotating the lead screw 2136. The rotation of the lead screw 2136 can be achieved by a hand wheel or a motor. Because this adjustment is not frequently used, a hand wheel can be used to reduce equipment costs. The guide cylinder 2132 is extended to the roller 2139, which is in contact with the steel plate. The steel plate is placed on the roller 212 at the upper end of the pushing frame 211. At this time, the steel plate may be in an inclined state, and then the guide assembly 213 is actuated, and the output shaft of the guide cylinder 2132 is extended, driving the guide brackets 2131 on both sides to approach the steel plate at the same time, and then the roller 2139 is in contact with the steel plate. Under the extrusion, the position of the steel plate is corrected, and then the forward component 22 is activated, the servo motor 222 is started, and the sliding plate 2211 on the linear slide mold drives the adapter frame 223 to move. At this time, the output shaft of the clamping cylinder extends out, driving the upper clamping plate 225 to rise. During the forward advancement of the adapter frame 223, the steel plate enters between the upper clamping plate 225 and the lower clamping plate 224. At this time, the output shaft of the clamping cylinder retracts, the upper clamping plate descends, clamps the steel plate, and then the adapter frame 223 continues to move forward to send the steel plate to the cutting component 23. The servo motor 222 can remember the position of the steel plate in the clamped state. Through program control, it can be known how much distance is needed to be transported for the first feeding to the cutting machine, and program control is simplified.

[0104] The pushed steel plate enters the cutting assembly 23 between the upper plate 233 and the guide plate 234, and is then cut to a set width by the pressing plate 232 that moves up and down repeatedly. The cutting of this part can be achieved by using a conventional cutting unit and is not specifically limited in the present application. For the last plate of the steel plate, the anti-dropping assembly 236 is actuated, the lifting cylinder 2363 first descends, and then the pushing cylinder 2361 is actuated, and the lifting cylinder 2363 and the pushing rod 2364 are driven forward by the pushing plate 2362 to push the last cut steel plate onto the receiving belt 24, and then transmitted to the next process through the receiving belt 24. The entire structure can guide the steel plate and feed the material accurately at the same time, and can prevent the last steel plate from dropping. It has higher practicality and better stability, and improves the reliability and cutting accuracy of the equipment.

[0105] During the unloading process, firstly, the positions of the side baffles 34 and the rear baffle 35 relative to the unloading trolley 32 are adjusted according to the specifications of the unloading steel plates, so as to ensure that the steel plates are ready to fall into the unloading interval formed by the front guide plate 33, the side baffles 34 and the rear baffle 35. The lifting trolley 38 is set corresponding to the unloading interval. When the material is started to be received, the lifting trolley 38 is at the highest point. As the number of steel plates increases, the height of the lifting trolley 38 gradually decreases, so that the lowered drop inside reduces the impact of the steel plates on the lifting trolley 38 and improves the stability of the structure. Since the lifting trolley 38 and the unloading trolley 32 are separately arranged, the specifications of the lifting trolley 38 can be replaced at any time, which is convenient and quick. The structure is separated from the cutting part, which is convenient for the transportation of materials and reduces the intensity of labor. Moreover, the specifications are adjustable, which is suitable for receiving steel plates of different specifications and has a wider applicability.

[0106] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
