Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a vertical and horizontal shear mechanism for plates. Background Art

[0002] A shearing machine is a type of sheet metal cutting equipment widely used in industries such as industry, construction, and home furnishing. It boasts high efficiency, precision, and flexibility. It primarily consists of a shearing unit, a feed mechanism, and a control system. The shearing unit is the core component, employing a pair of shear blades with cutting edges that reciprocate on a pair of tracks perpendicular to the cutting direction to achieve both vertical and horizontal cuts. The feed mechanism is responsible for delivering the sheet metal into the cutting area, while the control system automates the entire cutting process.

[0003] During actual use, the feeding device first feeds the metal sheet into the cutting area, and then the shearing knife in the shearing unit reciprocates under the command of the control system to cut the sheet into strip products of the required size and shape. Finally, the winding device rolls the cut strip products into coils for subsequent processing and use. The two shearing knives of the existing longitudinal and transverse shearing machine are fixedly installed on the frame. Although the stability of the shearing knife during use is improved, due to the difference in width of different models of plates, different areas of the shearing knife are used unevenly, resulting in excessive use of the part near the middle of the shearing knife, while the frequency of use of the parts on both sides is too low, thereby reducing the utilization rate and service life of the shearing knife. The fixed shearing knife position cannot be adjusted in time to compensate for this wear, thereby affecting the shearing accuracy. In addition, if the gap between the shearing blades is uneven, it will also lead to uneven force, resulting in a step phenomenon at the shearing point of the plate, thereby affecting the cutting quality of the plate.

[0004] Therefore, a kind of plate longitudinal and transverse shears mechanism is needed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The balancing assembly includes a mounting frame 201 disposed on a side away from the two shear blades 104. A screw rod 202 is rotatably connected within the two mounting frames 201. The two screw rods 202 are threadedly connected to two connecting plates 203. The four connecting plates 203 are connected to the shear blades 104 via a fixing assembly. A motor 204 is provided on one side of the two mounting frames 201. The output ends of the two motors 204 are connected to the screw rod 202. The two mounting frames 201 are provided with a linkage assembly for linking the two screw rods 202.

[0024] It should be noted here that: through the setting of the balancing component, under the mutual cooperation of the fixing component and the pushing component, while ensuring the stability of the shear knife 104 during use, the movement of the two shear knives 104 after one shearing is utilized to increase the use area of the shear knife 104, thereby reducing the utilization rate and cutting accuracy of the shear knife 104 due to local excessive use of the shearing edge of the shear knife 104, thereby improving the use efficiency of the shear knife 104 and the shearing quality of the plate.

[0025] It is worth noting that as an existing technology, the specific structure and working principle of the longitudinal and transverse shearing machine have been mastered by people in this field and will not be described in detail here.

[0027] It should be noted here that: by providing the fixing assembly, the shearing knife 104 is easily installed and disassembled while ensuring the secure installation of the shearing knife 104, thereby ensuring the stability of the shearing knife 104 during use.

[0028] See also Figure 3 The linkage assembly shown in the figure includes a linkage rod 401 rotatably connected to the side of the two mounting frames 201 away from the motor 204, one end of the two linkage rods 401 is connected to the screw rod 202, the side walls of the two linkage rods 401 are fixedly connected to the first sprocket 403, and the two first sprockets 403 are connected by a chain 402. The mounting frame 102 is provided with a tightening assembly for tightening the chain 402;

[0029] It should be noted that: by setting up the linkage assembly, one motor 204 is used to drive the two screw rods 202 to rotate synchronously, and further drive the two shearing knives 104 to move synchronously, thereby saving energy expenditure.

[0030] See also Figure 3The tensioning assembly shown in the figure includes a mounting plate 501 fixedly connected to one side of the mounting frame 102. The mounting plate 501 is connected to a U-shaped plate 502 on the side close to the chain 402 through two telescopic components. The U-shaped plate 502 is connected to a second sprocket 504 via a rotating shaft 503. The chain 402 is slidably connected to the second sprocket 504.

[0031] It should be noted that: by setting the tensioning assembly, the chain 402 is always in a tensioned state, thereby ensuring the synchronous transmission accuracy of the two shearing knives 104.

[0032] See also Figure 3 The telescopic assembly shown in the figure includes a telescopic tube 601 fixedly connected to the side of the mounting plate 501 close to the U-shaped plate 502, the telescopic tube 601 is slidably connected to the telescopic rod 602, one end of the telescopic rod 602 is connected to the U-shaped plate 502, the other end of the telescopic rod 602 is located in the telescopic tube 601 and fixedly connected to the telescopic plate 603, the side of the telescopic plate 603 away from the telescopic rod 602 is fixedly connected to a spring 604, the other end of the spring 604 is connected to the bottom wall of the telescopic tube 601;

[0033] It should be noted here that: by providing the telescopic assembly, a telescopic space is provided for the second sprocket 504, so that the chain 402 is always in a taut state.

[0034] Working principle: When using the longitudinal and transverse shearing machine to shear a plate, the plate is first fed into the cutting area, and then the plate is conveyed by two conveyor rollers 103. After the two conveyor rollers 103 convey the plate to a certain length, the rotation of the conveyor rollers 103 is stopped, and then the pushing assembly is used to push the two shearing blades 104 closer to each other. Thus, under the shearing action of the two shearing blades 104, the plate is sheared and cut into strip products of the required size and shape.

[0035] After the two shearing knives 104 have sheared the plate once, the pushing assembly drives the two shearing knives 104 to move away from the plate. In the process of the two shearing knives 104 moving away from the plate, the motor 204 is started to drive the screw rod 202 to rotate. In the process of the screw rod 202 rotating, the two connecting plates 203 are driven to move by the threaded engagement transmission effect of the screw rod 202 and the connecting plate 203 and the guiding effect of the mounting frame 201. As a result, in the process of the connecting plate 203 moving, the shearing knives 104 are driven to move.

[0036] In the process of the motor 204 driving the screw rod 202 to rotate, the other screw rod 202 will be driven to rotate under the transmission action of the first sprocket 403 and the chain 402, so that the two screw rods 202 are driven to rotate synchronously by one motor 204, and the two shearing knives 104 are further driven to move synchronously, thereby increasing the use area of the shearing knives 104 by the movement of the two shearing knives 104, reducing the reduction in the use rate and cutting accuracy of the shearing knives 104 due to the local excessive use of the shearing edge of the shearing knives 104, and thus improving the use efficiency of the shearing knives 104 and the shearing quality of the plate;

[0037] In the process of adjusting the shearing areas of the two shearing knives 104, the shearing knives 104 are constantly moving closer to or away from each other. At this time, under the elastic action of the telescopic component, the second sprocket 504 on the rotating shaft 503 drives the chain 402 to always be in a taut state, thereby ensuring the synchronous transmission accuracy of the two shearing knives 104.

[0038] Example 2

[0039] See also Figure 4 This embodiment further explains Example 1. The pushing assembly shown in the figure includes an operating plate 701 fixedly connected to the side of the mounting frame 102 away from the shear blade 104. A cylinder 702 is provided on the side of the operating plate 701 away from the base 101. The output end of the cylinder 702 is connected to the mounting frame 201.

[0040] It should be noted that: by setting the pushing assembly and utilizing the pushing force of the cylinder 702, the two shearing blades 104 are moved closer to or away from the plate, thereby achieving the shearing operation on the plate.
