Description

Technical Field

[0001] The present application relates to the field of sheet metal processing machinery, and in particular to a sheet metal slitting machine and a slitting method. Background Art

[0002] As an important equipment in the field of sheet processing, sheet slitting machines are widely used in the cutting process of various sheets. With the increasing requirements of manufacturing industry for processing accuracy and efficiency, sheet slitting machines not only need to have the characteristics of high efficiency, but also must meet the diversified needs in different application scenarios. For example, in many industrial production, the cutting of sheets not only requires that their width conform to specific dimensions, but also must be able to adjust the length of the sheets according to different needs to adapt to the changing processing requirements. Therefore, the development and technical improvement of sheet slitting machines have always been one of the focuses of industry attention. The sheet slitting machines in related technologies mainly include three components: conveying module, slitting module and cutting module. Among them, the conveying module is responsible for transporting the sheet to the specified position; the slitting module cuts the sheet into the required width through a pair of slitting rollers; and the cutting module further cuts the sheet with the divided width to the expected length. In actual application, this technical solution has been able to meet production needs for the processing of sheets of conventional sizes. At the same time, in order to improve production efficiency, most slitting machines are also integrated with automatic control systems, which further improves the speed and accuracy of sheet processing. However, the current sheet metal slitting machines have an obvious flaw: their cutting modules can only cut sheets to a fixed length. This means that when sheets of different widths and lengths need to be processed, the traditional batch operation method is inadequate. Especially in some specific scenarios, such as customized production or small batch and multi-variety operation environments, sheet metal slitting machines often cannot flexibly respond to the needs of different widths and lengths, resulting in low production efficiency and difficulty in meeting customer personalized needs. Summary of the invention

By adopting the above technical solution, the mounting seat slidably connected to the retraction frame cooperates with the two ends of the retraction elastic member to respectively against the mounting seat and the slider, so that the retraction elastic member can adjust the preload force of the retraction elastic member through the against action of the adjustment rod in the adjustment hole and the mounting seat, thereby accurately controlling the retraction force of the retraction mechanism and improving the stability and accuracy of the plate during retraction. Preferably, the machine body is provided with a support frame, the support frame is connected to a support roller frame, the support roller frame includes a frame and a plurality of support rollers rotatably connected to the frame, and the tops of the plurality of support rollers extend out of the top wall of the frame.By adopting the above technical solution, the setting of the support frame and the support roller frame can provide stable support for the plate, avoid the plate from being offset or deformed during the stripping and cutting process, and improve the processing accuracy; the top of the support roller extends out of the top wall of the frame, which can ensure that the plate is stable and smooth during the movement, and further improve the working stability and reliability of the plate stripping machine. In particular, for the slats located in the middle position that need to extend the cutting module first and then retract for cutting, the long part needs to be effectively supported by the support frame after extending the cutting module, otherwise it is easy to deform greatly. Preferably, the support frame is provided with a storage groove, the support roller frame is rotatably connected to the inner wall of the storage groove, and the support frame is provided with a support drive for driving the support roller frame to rotate. By adopting the above technical solution, the storage groove set on the support frame enables the support roller frame to be rotatably connected to the inner wall of the storage groove, and the support roller frame is driven to rotate by the support drive, thereby realizing the effective storage and expansion of the support roller frame, facilitating the adjustment of the position of the support roller frame according to different processing requirements, and improving the stability and flexibility of the plate stripping process. Preferably, the frame is provided with a support foot at the end away from the rotational connection between the frame and the storage slot, and the frame is provided with a support foot drive for driving the support foot to rotate. By adopting the above technical solution, the frame is provided with a support foot at the end away from the rotational connection between the frame and the storage slot, and the frame is provided with a support foot drive for driving the support foot to rotate, so that when the support roller frame extends out of the storage slot, the support foot can be rotated to contact the ground by the support foot drive to enhance the stability of the support roller frame and ensure the smooth transportation of the plate during the stripping process. Preferably, the machine body is provided with a leveling module, and the leveling module includes a plurality of leveling rollers rotatably connected to the machine body, and the plurality of leveling rollers are staggered up and down in sequence to stably clamp the plate in the leveling channel formed between the plurality of leveling rollers.

Preferably, the machine body is provided with a guide module, which includes a pair of clamping rollers for limiting the height position of the plate and a pair of guide wheels for limiting the lateral position of the plate, and the clamping rollers and guide wheels are both rotatably connected to the machine body. By adopting the above technical solution, the clamping rollers in the guide module can limit the height position of the plate to ensure the stability and accuracy of the plate during the stripping process; the guide wheels can limit the lateral position of the plate to prevent the plate from deviating during the transmission process, thereby improving the accuracy and quality of the plate stripping.

[0010] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0011] The inventor of the present application has found that the sheet slitting machine in the related art includes a conveying module, a slitting module 4 and a cutting module 5. The sheet 7 is first processed into the required width by the slitting module 4, and then the sheet 7 is processed into the required length by the cutting module 5. However, the prior art has the following defects: its cutting module 5 can only cut the sheet 7 as a whole into the required length. For example, after the slitting module 4 divides the sheet 7 into strips of two widths, it can only cut it into strips of different widths and the same length, and cannot meet the situation of a small amount of different widths and different lengths required in the actual processing process. For this reason, the present application mainly adopts the following scheme to achieve the processing effect of different widths and different lengths of the sheet 7. The present application is further described in detail below in conjunction with the accompanying drawings.

[0012] The present application embodiment discloses a plate slitting machine. Figure 1 and Figure 2 A plate slitting machine includes a machine body 1 and a guide module 2, a leveling module 3, a slitting module 4, a cutting module 5 and a driving module for conveying or retracting a plate 7 arranged on the machine body 1. The overall processing process is to convey the plate 7 to the inside of the machine body 1 through the guide module 2, and then to undergo leveling, slitting (fixed width) and cutting (fixed length) in sequence. During the cutting process, the driving module needs to be cooperated to retract the plate 7, so as to cut the side strips and the middle strips of the plate 7 at different lengths.

[0013] Reference Figure 3 The guide module 2 includes a pair of clamping rollers 21 for limiting the height position of the plate 7 and a pair of guide wheels 22 for limiting the lateral position of the plate 7. The two clamping rollers 21 are rotatably connected to the machine body 1 through bearings. The axial directions of the two clamping rollers 21 are horizontally arranged and there is a gap between the two clamping rollers 21 for the plate 7 to pass through, thereby limiting the vertical height of the plate 7. The two guide wheels 22 are also rotatably connected to the machine body 1 through bearings. The axial directions of the guide wheels 22 are placed vertically, and the side walls of the guide wheels 22 are circumferentially provided with an annular groove for the plate 7 to be embedded in, thereby limiting the lateral position of the plate 7.

[0014] Reference Figure 4 The leveling module 3 includes leveling rollers 31, and the leveling rollers 31 are rotatably connected to the side wall of the machine body 1 through bearings. The leveling rollers 31 are staggered up and down in sequence to stably clamp the plate 7 in the leveling channel formed between the leveling rollers 31. The leveling rollers 31 realize passive rotation through friction with the plate 7, so when the plate 7 needs to be retracted, it will not affect the retraction of the plate 7.

[0015] Reference Figure 5The slitting module 4 includes a pair of slitting rollers 41, which are connected to the side wall of the machine body 1 through bearings. The slitting rollers 41 slit the plate 7 through roller cutters 42 installed on the outside thereof. In this embodiment, the upper and lower roller cutters 42 relatively arranged on the two slitting rollers 41 are not completely symmetrical, but are staggered. The plate 7 is cut through the staggered gaps between the two roller cutters 42 to process a gap of a certain width. The machine body 1 is provided with a slitting drive 43, which is a motor for driving the slitting rollers 41 to rotate. The slitting rollers 41 are made of high-strength steel to ensure stability and durability.

[0016] Reference Figure 6 The cutting module 5 includes two cutting modules 51, and both cutting modules 51 are slidably connected to the machine body 1. Each cutting module 51 includes a cutting upper die 511 located at the top and a cutting lower die 512 located at the bottom. The machine body 1 is provided with a cutting frame 52 for installing the cutting upper die 511. The cutting upper die 511 and the cutting lower die 512 are installed by independent driving mechanisms and sliding mechanisms respectively, so that the cutting upper die 511 can move vertically and horizontally relative to the cutting frame 52, and the cutting lower die 512 can move vertically and horizontally relative to the machine body 1. Since the linear driving mechanism and the sliding mechanism are prior arts in the art, they are not described in detail in this embodiment. Accurate cutting at different positions can be achieved as a whole through two independent cutting modules 51.

[0017] Reference Figure 7 and Figure 8 In this embodiment, the conveying module is a retraction mechanism 6, which is used to control the conveying, stopping and retraction of the plate 7, so as to cooperate with the two cutting modules 51 to cut the two side strips and the middle strip of the plate 7 at independent positions. The machine body 1 is provided with a retraction frame 61, and the retraction mechanism 6 includes a pair of retraction rollers 62. The retraction rollers 62 are made of high-strength steel. The retraction rollers 62 are connected to the bearing seat in the machine body 1 through the shaft neck, and the bearing seat provides stable support for the rotation of the retraction rollers 62. The rotation of the retraction rollers 62 is driven by the retraction drive member, and the retraction drive member adopts a servo motor, which has high control accuracy and fast response speed. The servo motor can adjust the output speed and torque according to the requirements of the control system, so as to realize the precise control of the retraction rollers 62. The servo motor can provide stable power support under high-speed operation. The transmission system between the servo motor and the retraction roller 62 adopts a synchronous belt drive mode. The synchronous belt is made of polyvinyl chloride material, which has high tensile strength and wear resistance, ensuring that it can maintain a good transmission effect under long-term operation.

[0018] Reference Figure 7 and Figure 8The surface of the retracting roller 62 is covered with an anti-skid cover 64, which is made of rubber. The rubber material is natural rubber, which has good elasticity, wear resistance and anti-aging properties, and can effectively enhance the grip between the retracting roller 62 and the plate 7. The inner side of the anti-skid cover 64 is integrally formed with a plurality of inserting strips 65 parallel to the axial direction. Correspondingly, the outer side of the retracting roller 62 is parallel to the axial direction and is provided with a slot 650 for inserting the inserting strips 65. After the anti-skid cover 64 is covered on the outer side of the retracting roller 62, it can be more stable under the cooperation of the inserting strips 65 and the slot 650, and it is not easy to cause invalid rotation.

[0019] Reference Figure 7 and Figure 8 The specific installation method of the two retracting rollers 62 is as follows: the two retracting rollers 62 are arranged up and down, and the retracting roller 62 located at the bottom is connected to the machine body 1 by a rotation connection with the fixed position of the retracting frame 61. The retracting frame 61 is provided with a slide groove 660, and a slider 66 and a mounting seat 661 are slidably arranged inside the slide groove 660. The material of the slider 66 and the mounting seat 661 is selected from high-strength aluminum alloy, which has a low friction coefficient and a high load-bearing capacity. The mounting seat 661 is located above the slider 66 and a retracting elastic member 67 is arranged between the two. The retracting elastic member 67 is a spring, and the spring material is 65Mn steel wire, which has high elasticity and fatigue resistance.

[0020] The retraction roller 62 located at the top is rotatably connected to the slider 66 through a bearing. The retraction frame 61 is a door-shaped frame, and the crossbar at the top is detachably connected to the vertical bar on the side by bolts. An adjustment hole 680 is vertically arranged at the top of the retraction frame 61, and an adjustment rod 68 is inserted into the inner thread of the adjustment hole 680. The bottom of the adjustment rod 68 abuts against the mounting seat 661 to compress the retraction elastic member 67. The compression degree of the retraction elastic member 67 can be achieved by adjusting the position of the bottom of the adjustment rod 68, thereby adjusting the clamping degree of the two retraction rollers 62 on the plate 7.

[0021] Reference Fig. 9The rear end of the machine body 1 is also provided with a support frame 8, which is used to support the cut side plates 7 and / or the middle plates 7 that have not been cut yet. The support frame 8 is provided with a storage groove 80, and a support roller frame 81 is rotatably connected to the storage groove 80 through a bearing. The support roller frame 81 is composed of a frame 811 and a plurality of support rollers 812 rotatably connected to the frame 811. When the support roller frame 81 is in a horizontal state, the tops of the plurality of support rollers 812 all extend out of the top wall of the frame 811. The side wall of the support frame 8 is provided with a support driving member 82, which is a motor, and is used to drive the support roller frame 81 to rotate out of the storage groove 80 to a horizontal state to support the plates 7. It can also be stored when restricted to improve the utilization rate of space. The support roller 812 is made of stainless steel, has good corrosion resistance and wear resistance, and is suitable for supporting plates 7 in various environments. The frame 811 is made of high-strength aluminum alloy, which has a high weight ratio and good corrosion resistance, and can effectively ensure the stability of the entire support roller frame 81.

[0022] The rotation connection between the support roller frame 81 and the storage slot 80 is specifically carried out through bearings and pins. The bearings are precision rolling bearings with high load-bearing capacity and wear resistance. The frame 811 is rotatably provided with a support foot 83 at the end away from the rotation connection between the frame 811 and the storage slot 80. During the opening process of the support roller frame 81, the support foot 83 can be opened synchronously with the rotation of the frame 811. The rotation of the support foot 83 is realized by the support foot drive 84, which adopts an electric cylinder and is fixed to the support frame 8 by bolts.

[0023] The implementation principle of this embodiment is: after the sheet 7 is cut into strips of the required width by the stripping module 4, the strips located on the side are first cut by the cutting module, and further, the strips on the left and right can be cut respectively, so as to achieve different length control of the strips on the left and right. When the strips on both sides are cut to the middle strip to meet the required cutting length and there is no obstruction on both sides of the position to be cut, the sheet 7 can be retracted by the retracting mechanism 6, and then the middle strip can be cut by any cutting module. In this way, each strip can be cut at different positions, so as to achieve the processing of sheets 7 of different widths and lengths.

[0024] The present application also discloses a method for stripping a plate: Reference Fig.10 Taking the plate 7 being divided into slats A, B and C by the slitting module 4 as an example, the direction of the arrow in the figure is the conveying direction of the plate 7. The slats A, B and C require different processing lengths. The dotted lines A1, A2, B1, C1 and C2 are the positions to be cut of the slats A, B and C. B1 is between A1 and A2, and B1 is also between C1 and C2. A1 is in front of C1, and A2 is in front of C2.

[0025] In the actual processing process, the plate 7 is first controlled to be conveyed to A1 and located under the cutting module 51, and the left cutting module 51 is controlled to cut only at A1; then the plate 7 is conveyed to C1 and located under the cutting module 51, and the right cutting module 51 is controlled to cut only at C1, and then the plate 7 is conveyed to A2 and located under the cutting module 51 for cutting, and then the plate 7 is conveyed to C2 and located under the cutting module 51 for cutting. When cutting A2 and C2, B1 has passed the cutting module 5, and therefore, after A2 and C2 are cut and B1 is exposed, the plate 7 is controlled to retract to B1 and be located under the cutting module 51 again through the retracting mechanism 6, and then the cutting module 51 can be used to cut B1.

[0026] The implementation principle of a plate stripping method in an embodiment of the present application is: based on the above-mentioned stripping method, plates 7 of different widths and lengths can be processed in batches in the same batch in a specific order in conjunction with the return of the plates 7. There is no need to cut individual strips one by one after stripping, which is more efficient.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
