Description

Technical Field

[0001] The invention relates to the technical field of metal part shearing, and in particular to a metal part shearing device and a processing method thereof. Background Art

[0002] In the metal processing industry, the shearing of metal sheets is a crucial process. The shearing accuracy and surface quality of metal sheets directly affect the smooth progress of subsequent processing steps and the performance and quality of the final product. However, in the actual production process, metal sheets often encounter the problem of easy deformation at the shearing point during the shearing process, which not only reduces the product qualification rate, but also increases production costs and time costs.

[0003] In order to effectively alleviate the deformation problem of metal sheets during the shearing process, the preheating method is generally used in the prior art. Preheating can reduce the strength and hardness of the metal, thereby reducing the shearing force required during shearing, helping to reduce stress concentration and deformation during the shearing process, and improving shearing accuracy and surface quality. Preheating can also make the internal structure of the metal more uniform, which is conducive to improving the flatness and smoothness of the sheared surface.

[0004] However, the preheating method in the prior art is to heat the portion of the metal sheet other than the cutout, and then achieve the preheating effect at the cutout by heat transfer. This method not only causes unnecessary energy waste, but also due to the hysteresis and unevenness of heat transfer, the temperature at the cutout is often difficult to reach the ideal preheating temperature range. Too high a preheating temperature may cause the metal sheet to overheat as a whole, which will not only affect the shearing quality and subsequent processing performance, but may also reduce the mechanical properties of the material. Too low a preheating temperature may not effectively reduce the strength and hardness of the metal, thereby failing to effectively reduce shear deformation and improve shearing accuracy.

[0023] As a preferred solution of the metal part shearing equipment of the present invention, the second telescopic member is telescopically extended and retracted vertically, and the structural composition of the second telescopic member is the same as that of the first telescopic member.

[0024] The processing method using the above metal shearing device includes the following steps:

[0025] Step 1: First, the metal sheet to be sheared is conveyed to the shearing table through the first roller conveyor, and then the position of the metal sheet is adjusted to ensure that the cut of the sheet corresponds to the cutting disc on the grinding wheel cutter;

[0026] Step 2: Then, the lifting plate is driven downward by the hydraulic cylinder, and the lifting plate drives the grinding wheel cutter, the pressing mechanism, the incision preheating mechanism and the stabilizing mechanism to move downward. The pressing block in the pressing mechanism first contacts the metal sheet to apply a preliminary fixing force. The heating plate and the pressing block in the incision preheating mechanism contact the metal sheet synchronously, and the heating plate directly contacts the incision of the sheet to start preheating the incision.

[0027] Step 3: Then, the hydraulic cylinder continues to drive the lifting plate to move downward, so that the grinding wheel cutter gradually approaches the metal plate. During this process, the pressing block remains in place under the limiting effect of the metal plate, and the first force rod continues to move downward with the lifting plate and the first fixed plate under the action of the first spring. The first spring is compressed, and the first force rod drives the push rod to move downward. Then, the arc-shaped structure at the bottom end of the push rod applies a driving force to the inclined surface of one side of the driving groove inside the driving block. Under the push of the push rod, the driving block drives the push-pull rod and the heating plate to move to both sides, freeing up shearing space for the grinding wheel cutter; when the push rod moves through the inclined groove to the lower part of the driving groove, the driving block stops applying a driving force, and the push-pull rod and the heating plate stop moving;

[0028] Step 4: In addition, as the driving block moves, the convex teeth drive the gear meshing with it to rotate, and the gear drives the gears at both ends to rotate synchronously through the rotating shaft. When the gears at both ends rotate, the rack moves downward through meshing with the rack, and then drives the second fixed plate to move downward through the extension rod. The second fixed plate applies a downward force to the vertical plate and the second force rod by compressing the second telescopic member, and the second force rod applies a downward force to the pressing block, thereby ensuring that the pressing block can effectively press and fix the metal plate;

[0029] Step 5: The abrasive wheel cutter completes the shearing action under the drive of the hydraulic cylinder. After the shearing is completed, the hydraulic cylinder drives the lifting plate to move upward and reset, and the lifting plate drives the abrasive wheel cutter and the first fixed plate to move upward. The first fixed plate drives the push rod to move upward through the first force rod. When the push rod is pulled out of the driving groove, the driving block moves and resets toward the direction of the abrasive wheel cutter under the rebound force of the second spring, and the heating plate is also reset accordingly. When the moving rod contacts the top wall in the moving groove, the pressing block and the heating plate are moved away from the metal plate by the pulling force of the moving rod, and a shearing is completed;

[0030] Step 6: Repeat the above steps to perform the next cutting operation.

[0031] Beneficial effects of the present invention:

[0032] 1. In the present invention, before the grinding wheel cutter is driven by the hydraulic cylinder to complete the shearing action, the incision of the metal plate is directly preheated by a pair of heating plates, and the heating temperature is controlled by the temperature sensor built into the heating plate, which is not easy to cause energy waste and can make the temperature at the incision reach the ideal preheating temperature range, thereby effectively reducing shear deformation and improving shearing accuracy. In addition, before the grinding wheel cutter reaches the incision, the pair of heating plates can automatically move to both sides to free up shearing space for the grinding wheel cutter, with a high degree of automation and convenient for people to use.

[0033] 2. Before the hydraulic cylinder drives the abrasive wheel cutter to complete the shearing action, the hydraulic cylinder also synchronously drives the lifting plate and its auxiliary mechanism to move downward. The pressing block first contacts the metal sheet and applies a preliminary fixing force. When the hydraulic cylinder continues to drive the lifting plate downward, the pressing block remains in place due to the limiting effect of the metal sheet, and the first force rod continues to move downward under the action of the first spring. The first force rod applies a driving force to the driving block through the push rod, and the driving block drives the push-pull rod and the heating plate to move to both sides, freeing up shearing space for the abrasive wheel cutter, so that the abrasive wheel cutter can complete the shearing action. In addition, as the driving block moves, the convex teeth drive the gear to rotate, and the gear drives the gears at both ends to rotate synchronously through the rotating shaft, and then the gear and the rack meshing action moves the rack downward, and then drives the second fixed plate downward through the extension rod. The second fixed plate applies a downward force to the vertical plate and the second force rod by compressing the second telescopic member, and the downward force acts on the top of the pressing block, thereby ensuring the effective pressing and fixing of the metal sheet, thereby further improving the shearing accuracy.

[0050] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0051] Example 1

[0052] Reference Figure 1-9 , which is the first embodiment of the present invention, provides a metal shearing device, which mainly includes:

[0053] Shear unit 100, such as Figure 1 The shearing unit 100 includes a shearing table 101, a gantry 102 fixedly connected to the top of the shearing table 101 by bolts, a shearing mechanism 103 fixedly connected to the top of the gantry 102, a pair of pressing mechanisms 104 fixedly connected to the shearing mechanism 103, and a cut preheating mechanism 105 respectively connected to the pair of pressing mechanisms 104. A shearing groove 107 is provided on the top of the shearing table 101.

[0054] The first roller conveyor 200, such as Figure 1 The first roller conveyor belt 200 is located on the left side of the shearing station 101 and is used to transport the metal sheet to be sheared to the shearing station 101.

[0055] The second roller conveyor 300, such as Figure 1 The second roller conveyor 300 is located on the right side of the shearing table 101 and is used to remove the sheared metal sheet from the shearing table 101.

[0056] Specifically, Figure 2The shearing mechanism 103 includes a hydraulic cylinder 103-1 fixedly connected to the top of the gantry 102 by bolts, a lifting plate 103-2 fixedly connected to the bottom piston end of the hydraulic cylinder 103-1 by bolts, and a grinding wheel cutter 103-3 fixedly connected to the bottom of the lifting plate 103-2 by bolts. The cutting blade of the grinding wheel cutter 103-3 is arranged corresponding to the shearing groove 107 up and down. When shearing is performed, the lifting plate 103-2 is driven downward by the hydraulic cylinder 103-1, and the lifting plate 103-2 drives the grinding wheel cutter 103-3 to move downward to perform the shearing action.

[0057] Specifically, Figure 5-6 A pair of pressing mechanisms 104 are symmetrically arranged on the left and right sides of the cutting blade of the grinding wheel cutter 103-3. The pressing mechanism 104 includes a first fixed plate 104-1 fixedly connected to one side of the lifting plate 103-2 and a pressing assembly 104-2 fixedly connected to the bottom of the first fixed plate 104-1.

[0058] The pressing assembly 104-2 includes a pressing block 104-21, a groove is formed on the top of the pressing block 104-21, a first spring 104-22 is fixedly connected to the bottom wall of the groove, a first force rod 104-23 is slidably connected to the notch of the groove, and the bottom end of the first force rod 104-23 is fixedly connected to the top end of the first spring 104-22;

[0059] A movable groove 104-24 connected with the groove is provided on the side of the pressing block 104-21 away from the grinding wheel cutter 103-3, and a movable rod 104-25 slides through the movable groove 104-24, and the inner end of the movable rod 104-25 is fixedly connected to the first force applying rod 104-23, so that the movable rod 104-25 can be raised and lowered synchronously with the first force applying rod 104-23, and a push rod 104-26 is fixedly connected to the bottom of the outer end of the movable rod 104-25, and the bottom end of the push rod 104-26 is an arc-shaped structure, and the left and right sides of the pressing block 104-21 are provided with mutually connected through grooves 104-27 below the groove, and the inner top wall of the through groove 104-27 is provided with a convex tooth groove 104-28 connected at both ends.

[0060] When the lifting plate 103-2 is driven downward by the hydraulic cylinder 103-1, the first fixed plate 104-1 moves along, and the first fixed plate 104-1 drives the pressing block 104-21 to move downward through the first force rod 104-23. When the bottom end of the pressing block 104-21 contacts the metal sheet, a preliminary fixing force is applied. At this time, the grinding wheel cutter 103-3 is still not in contact with the metal sheet. Then, the lifting plate 103-2 is driven downward by the hydraulic cylinder 103-1, so that the grinding wheel cutter 103-3 gradually approaches the metal sheet. During this process, the pressing block 104-21 remains in place due to the limiting effect of the metal plate, and the first force rod 104-23 continues to move downward with the lifting plate 103-2 under the action of the first spring 104-22. The first force rod 104-23 drives the push rod 104-26 to move downward. While the first force rod 104-23 squeezes the first spring 104-22, it can also increase the pressing force of the pressing block 104-21 on the metal plate, thereby improving the fixing effect of the pressing block 104-21 on the metal plate.

[0061] Specifically, Figure 7 A pair of incision preheating mechanisms 105 are symmetrically arranged, and the incision preheating mechanism 105 includes a push-pull rod 105-1 arranged horizontally, and the push-pull rod 105-1 slides through the through slot 104-27. A heating plate 105-2 is fixedly connected to the bottom of one end of the push-pull rod 105-1 facing the grinding wheel cutter 103-3. The heating plate 105-2 has built-in electric heating elements and temperature sensors. The temperature sensor is connected to an external temperature control system. The temperature control system includes a PID controller and an actuator. When the heating plate is powered on, the electric heating element starts to work, converts electrical energy into thermal energy, and increases the surface temperature of the heating plate. The temperature sensor monitors the temperature of the heating plate in real time and feeds back the temperature data to the PID controller. The PID controller calculates the heating power that needs to be adjusted based on the preset temperature value and the actual temperature value fed back by the temperature sensor. The actuator adjusts the current or voltage of the heating element according to the output signal of the PID controller, thereby realizing precise adjustment of the heating power, and then the temperature at the incision can reach the ideal preheating temperature range, thereby effectively reducing shear deformation and improving shearing accuracy. The opposite sides of the heating plates 105-2 in a pair of incision preheating mechanisms 105 are movably fitted together. The purpose of this arrangement is to be able to heat the incision. The bottom of the heating plate 105-2 is flush with the bottom of the pressing block 104-21, so that the heating plate 105-2 can contact the plate synchronously with the pressing block 104-21. The top of the push-pull rod 105-1 is fixedly connected with convex teeth 105-3 in a linear array, and the convex teeth 105-3 are adapted to slide with the convex tooth groove 104-28.

[0062] like Figure 8, one end of the push rod 105-1 away from the grinding wheel cutting machine 103-3 is fixedly connected with a driving block 105-4. Driving grooves 105-6 that communicate with each other are formed on the upper and lower sides of the driving block 105-4. The side of the driving groove 105-6 close to the pressing block 104-21 is a vertical surface, and the upper part of the side away from the pressing block 104-21 is an inclined surface. The advantage of such a setting is that only the upper part of one side of the pressing block 104-21 is provided with an inclined surface. In this way, when the bottom end of the push rod 104-26 smoothly enters the lower part of the driving groove 105-6 by means of this inclined surface, the driving block 105-4 will stop moving. Furthermore, after the heating plate 105-2 vacates an appropriate cutting space for the grinding wheel cutting machine 103-3, it will not continue to move away from the cut. This design enables the heating plate 105-2 to effectively compensate for the temperature that may be reduced due to operation at the cut during the cutting process through heat transfer, ensuring the shearing quality. When the opposite sides of a pair of heating plates 105-2 are attached to each other, the arc structure at the bottom end of the push rod 104-26 is in movable contact with the upper part of the inclined surface. When the push rod 104-26 moves downward, the inclined surface can drive the driving block 105-4 to move away from the grinding wheel cutting machine 103-3. Furthermore, after the preheating of the cut is completed, a pair of heating plates 105-2 can be automatically opened to vacate a cutting space for the grinding wheel cutting machine 103-3, with a high degree of automation and convenience for people to use.

[0063] A reset assembly 105-5 is fixedly connected to the side of the driving block 105-4 away from the grinding wheel cutting machine 103-3. The top of the reset assembly 105-5 is fixedly connected to the pressing block 104-21.

[0064] Furthermore, as Figure 8 , the reset assembly 105-5 includes a first telescopic member fixedly connected to the side of the driving block 105-4 away from the grinding wheel cutting machine 103-3, a side plate 105-51 fixedly connected to one end of the first telescopic member away from the driving block 105-4, and a U-shaped bracket 105-52 fixedly connected to the top of the side plate 105-51. The open end of the U-shaped bracket 105-52 is fixedly connected to the front and rear sides of the pressing block 104-21;

[0065] As Fig. 9 , the first telescopic member expands and contracts horizontally. The first telescopic member includes a fixed sleeve 105-53 fixedly connected to the side plate 105-51, a telescopic rod 105-54 fixedly connected to the driving block 105-4, and a second spring 105-55 fixedly connected to the inner bottom wall of the fixed sleeve 105-53. One end of the telescopic rod 105-54 away from the driving block 105-4 is slidably fitted with the fixed sleeve 105-53 and fixedly connected to one end of the second spring 105-55. When the push rod 104-26 is withdrawn from the driving groove 105-6, the driving block 105-4 moves back to the direction of the grinding wheel cutting machine 103-3 under the resilience of the second spring 105-55, and the heating plate 105-2 also returns to its original position accordingly.

[0066] Example 2

[0067] Reference Figure 10-11 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the shearing unit 100 also includes a pair of stabilizing mechanisms 106 respectively connected to the pair of pressing mechanisms 104, and the pair of stabilizing mechanisms 106 are also respectively connected to a pair of incision preheating mechanisms 105.

[0068] Specifically, the stabilizing mechanism 106 includes a stabilizing pressing component 106-1 and a pressing drive component 106-2.

The pressing drive component 106-2 is connected to the pressing block 104-21, the stabilizing pressing component 106-1 and the convex tooth 105-3, and is used to drive the stabilizing pressing component 106-1 to apply pressing force.

[0069] Furthermore, the stable pressing assembly 106-1 includes a guide slide tube 106-11 fixedly connected to the side of the pressing block 104-21 facing the grinding wheel cutter 103-3, and a vertical plate 106-12 is slidably penetrated in the guide slide tube 106-11. A pair of second force application rods 106-13 are fixedly connected to the top of the vertical plate 106-12. The pair of second force application rods 106-13 are movably arranged on the front and rear sides of the first force application rod 104-23, and the bottoms of the pair of second force application rods 106-13 are supported on the top of the pressing block 104-21. There are mutually connected mounting grooves 104-14 on the left and right sides of 06-12, and the second telescopic member 106-15 is fixedly connected to the inner bottom wall of the mounting groove 104-14, and the second telescopic member 106-15 is fixedly connected to the top of the second fixed plate 106-16, and the second fixed plate 106-16 slides horizontally through the mounting groove 104-14, and the front and rear sides of the second fixed plate 106-22 are fixedly connected to extension rods 106-17, and the end of the extension rod 106-17 away from the second fixed plate 106-22 is vertically fixedly connected to a rack 106-18.

[0070] The pressing drive assembly 106-2 includes a pair of mounting plates 106-21 fixedly connected to the side of the pressing block 104-21 facing the grinding wheel cutter 103-3, a rotating shaft 106-22 is rotatably mounted between the pair of mounting plates 106-21, three gears 106-23 are fixedly sleeved on the rotating shaft 106-22, the bottom of the gear 106-23 located in the middle is meshed with the convex tooth 105-3, and the gears 106-23 located at both ends are meshed with a pair of racks 106-18 respectively facing the side of the grinding wheel cutter 103-3. The second telescopic member 106-15 is vertically telescopic, and the second telescopic member 106-15 has the same structural composition as the first telescopic member.

[0071] The remaining structures are the same as those of Example 1.

[0072] When the driving block 105-4 drives the heating plate 105-2 to move to both sides, the convex tooth 105-3 also moves accordingly, and the convex tooth 105-3 drives the gear 106-23 meshing with it to rotate, and the gear 106-23 drives the gears 106-23 at both ends to rotate synchronously through the rotating shaft 106-22. When the gears 106-23 at both ends rotate, the rack 106-18 is meshed with the rack 106-18 to move downward, and then the extension rod 106-17 is driven to drive the second gear 106-23 to rotate synchronously. The second fixed plate 106-16 moves downward, and the second fixed plate 106-16 applies a downward force to the vertical plate 106-12 and the second force rod 106-13 by compressing the second telescopic member 106-15. The second force rod 106-13 applies a downward force to the pressing block 104-21, thereby further ensuring that the pressing block 104-21 effectively presses and fixes the metal sheet, thereby improving the stability of the metal sheet during shearing, and further improving the shearing accuracy and shearing quality.

[0073] The processing method using the above metal shearing device is as follows: first, the metal sheet to be sheared is transported to the shearing table 101 through the first roller conveyor 200, and then the position of the metal sheet is adjusted to ensure that the sheet cut corresponds to the cutting blade on the grinding wheel cutter 103-3. Then, the lifting plate 103-2 is driven downward by the hydraulic cylinder 103-1, and the lifting plate 103-2 drives the grinding wheel cutter 103-3, the pressing mechanism 104, the cutting preheating mechanism 105 and the stabilizing mechanism 106 to move downward, and the pressing block 104-21 in the pressing mechanism 104 first contacts the metal sheet to apply a preliminary fixing force, and the heating plate 105-2 in the cutting preheating mechanism 105 and the pressing block 104-21 are synchronously contacted with the metal sheet, and the heating plate 105-2 is directly in contact with the cutting of the sheet to start preheating the cutting. Then, the hydraulic cylinder 103-1 continues to drive the lifting plate 103-2 to move downward, so that the grinding wheel cutter 103-3 gradually approaches the metal plate. In this process, the pressing block 104-21 remains in place under the limiting effect of the metal plate, and the first force rod 104-23 continues to move downward with the lifting plate 103-2 and the first fixed plate 104-1 under the action of the first spring 104-22. The first spring 104-22 is compressed, and the first force rod 104-23 drives the push rod 104-26 to move downward, and then, The arc-shaped structure at the bottom end of the push rod 104-26 applies a driving force to the inclined surface of one side of the driving groove 105-6 inside the driving block 105-4. Under the push of the push rod 104-26, the driving block 105-4 drives the push-pull rod 105-1 and the heating plate 105-2 to move to both sides, freeing up shearing space for the grinding wheel cutter 103-3; when the push rod 104-26 moves through the inclined groove to the lower part of the driving groove 105-6, it stops applying a driving force to the driving block 105-4, and the push-pull rod 105-1 and the heating plate 105-2 stop moving. In addition, with the movement of the driving block 105-4, the convex tooth 105-3 drives the gear 106-23 meshing with it to rotate, and the gear 106-23 drives the gears 106-23 located at both ends to rotate synchronously through the rotating shaft 106-22. When the gears 106-23 located at both ends rotate, the rack 106-18 moves downward through the meshing action with the rack 106-18, and then drives the second fixed plate 106-16 to move downward through the extension rod 106-17. The second fixed plate 106-16 applies a downward force to the vertical plate 106-12 and the second force rod 106-13 by compressing the second telescopic member 106-15, and the second force rod 106-13 applies a downward force to the pressing block 104-21, thereby ensuring that the pressing block 104-21 effectively presses and fixes the metal plate.The grinding wheel cutter 103-3 completes the shearing action under the drive of the hydraulic cylinder 103-1. After the shearing is completed, the hydraulic cylinder 103-1 drives the lifting plate 103-2 to move upward and reset. The lifting plate 103-2 drives the grinding wheel cutter 103-3 and the first fixed plate 104-1 to move upward. The first fixed plate 104-1 drives the push rod 104-26 to move upward through the first force rod 104-23. When the push rod 104-26 is out of the driving slot 105-6, the push rod 104-26 is pushed upward. When pulled out, the driving block 105-4 moves and resets in the direction of the grinding wheel cutter 103-3 under the action of the rebound force of the second spring 105-55, and the heating plate 105-2 is also reset. When the moving rod 104-25 contacts the inner top wall of the moving groove 104-24, the pressing block 104-21 and the heating plate 105-2 are moved away from the metal plate through the pulling force of the moving rod 104-25, completing one shearing operation, repeating the above steps to perform the next shearing operation.
