Description

Technical Field

[0001] The invention relates to the field of sheet metal processing equipment production, in particular to a sheet metal side bending and cutting equipment. Background Art

[0002] Under the pressure of large-scale production and rapid delivery, improving the production efficiency of sheet metal processing has become one of the key goals of enterprises. Modern manufacturing requires processing equipment that can complete a large number of high-quality sheet metal parts in a short period of time. The processing equipment includes cutting, bending, stamping and forming. Among them, the side bending and cutting processes of sheet metal during processing are the bottleneck links in the entire production process, and their processing speed directly affects the overall production efficiency.

[0003] In actual production, the design requirements of sheet metal parts are diverse, so different bending angles are needed to meet specific shape and functional requirements. For example, some electrical housings may need to be bent at different angles to form a specific installation structure or appearance. At the same time, when producing sheet metal housings of some specific shapes, they are first bent into shape, and then the excess side material needs to be removed. The equipment can accurately cut the bent sides, and different angles of cutting are required at the edges to ensure good fit with other components, so as to ensure that the various parts of the housing can be tightly connected while meeting the appearance requirements.

[0004] A sheet metal side bending and cutting device with Chinese patent application number 202322088576.5 includes a fixing mechanism, a bending mechanism and a cutting mechanism, wherein the fixing mechanism includes a base, an adjusting component arranged on the top of the base and a clamping component arranged on the top of the adjusting component, the clamping component clamps both ends of the sheet metal, and then drives the side to bend by a jack, and then cuts by moving to a cutting saw blade, but when the sheet metal is bent into different angles, the position and angle of the cutting saw blade cannot be automatically adjusted according to the bending angle. Specifically, the current technical solution relies on manual transfer of the bent sheet metal to the cutting position, which is convenient for the bent sheet metal. Sheet metal cutting, this manual operation mode has many disadvantages. It is difficult to fix sheet metal bent at different angles and dock it with the cutting saw blade of the cutting equipment, which reduces the accuracy of cutting and significantly increases the difficulty of fixing. In addition, when the sheet metal is bent, the bent sheet metal is manually moved to the cutting saw blade and then cut by the cutting equipment. This series of processing steps prolongs the cutting efficiency. Secondly, when the size of the sheet metal is different, the bending position changes, and the position of the cutting equipment needs to be adjusted. It cannot be adjusted according to the changes in the bending position of sheet metal parts of different sizes, which increases the complexity and workload of the operation.

[0005] Therefore, it is necessary to propose a sheet metal side bending and cutting device to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0057] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0058] like Figure 1-Figure 3 As shown, a sheet metal side bending and cutting device comprises a processing table 1, and two bending frames 12 are arranged on the top of the processing table 1 to move along the left and right directions. The bending frames 12 are plate-shaped structures with a large contact area, and the bending frames 12 are pushed by a hydraulic press to fix the sheet metal parts to ensure that the position of the sheet metal parts is stable during the bending and cutting process. A bending push frame 13 is arranged on one side of the top of the processing table 1 to move along the left and right directions, and a bending push frame 13 is arranged on one side for bending the sheet metal parts. The bent bending ball 14 and the bending push frame 13 are pushed by a hydraulic press to bend the bending ball 14 along the part of the sheet metal that needs to be bent. A bending seat 15 is arranged on the top of the processing table 1. The bending seat 15 is located below the sheet metal and is used to support the sheet metal to ensure the accuracy of bending. An electric push rod 16 is arranged above the processing table 1. A cutting ultrasonic wave 17 is installed on the moving end of the electric push rod 16. With the cooperation of the electric push rod 16, the cutting ultrasonic wave 17 is prompted to cut along the bent edge of the sheet metal.

[0059] like Figure 2-Figure 4As shown, the synchronous docking assembly 2 is arranged on the processing table 1, and is used for bending the sheet metal at different angles, and the cutting ultrasonic wave 17 can move accordingly and realize synchronous work; the synchronous docking assembly 2 includes: a U-shaped frame 21, whose horizontal end is an arc-shaped structure, and the arc shape is arranged to rotate along the bending seat 15 as the center point, and its two vertical ends are fixedly connected to the processing table 1, one of the vertical ends corresponds to the bending seat 15, and the other vertical end is arranged at the end away from the bending ball 14; a curved spring rod 22, which is plugged and installed between the two vertical ends of the U-shaped frame 21; a slide rail seat 23, which is a long structure, and the top of the slide rail seat 23 is connected to the U by a slide rail. The frame 21 is slidably connected; the adjusting rod 24 is threadedly connected to the bottom of the slide rail seat 23; the synchronous docking plate 25 is L-shaped, the synchronous docking plate 25 corresponds to the bending seat 15, and the side of the synchronous docking plate 25 facing away from the bending seat 15 is rotatably connected to the adjusting rod 24 through a bearing, and a limit rod is installed on one side of the synchronous docking plate 25 and at the upper and lower ends of the adjusting rod 24, and the end of the limit rod facing away from the synchronous docking plate 25 slides through the bottom of the slide rail seat 23; the connecting frame 26 is arranged on the side wall of the synchronous docking plate 25 and has an L-shaped structure, the electric push rod 16 is installed on the horizontal end of the connecting frame 26, and the cutting ultrasonic wave 17 is located on one side of the vertical end of the connecting frame 26.

[0060] It should be noted that the initial preparation and placement of the sheet metal are as follows: the sheet metal passes vertically between the two bending frames 12 on the processing table 1, and the part to be bent is extended on the bending seat 15. Then, the sheet metal is fixed by the two bending frames 12 to ensure the stability of the sheet metal in subsequent operations. Then, the adjustment rod 24 is rotated to drive the synchronous docking plate 25 to move along the sheet metal. The limit rod ensures that the synchronous docking plate 25 does not deviate during the movement until the horizontal end of the synchronous docking plate 25 contacts the end of the sheet metal. At the same time, it ensures that the top end of the sheet metal corresponds to the cutting ultrasonic wave 17, so as to prepare for the subsequent bending and cutting operations.

[0061] Synchronous operation of bending and cutting: Start the hydraulic press to drive the bending push frame 13 to move, and the bending ball 14 moves along the sheet metal to start bending the sheet metal. During the bending process, the sheet metal and the vertical end of the synchronous docking plate 25 are squeezed. Due to this squeezing effect, the synchronous docking plate 25 will be displaced. Since it is connected to the slide rail seat 23, it will cause the synchronous docking plate 25 and the slide rail seat 23 to slide along the U-shaped frame 21. The horizontal end of the U-shaped frame 21 is arc-shaped and rotated with the bending seat 15 as the center point, so that the synchronous docking plate 25 can adapt to the change of the bending angle of the sheet metal. At the same time, start the electric push rod 16 to drive the cutting ultrasonic wave 17 to move downward. When the synchronous docking plate 25 moves, the cutting ultrasonic wave 17 is worth noting that if the bending of the sheet metal is completed, the cutting ultrasonic wave 17 can continue to cut. If the sheet metal is still in the bending operation, the cutting ultrasonic wave 17 can stop after cutting, which effectively improves the processing efficiency and realizes the synchronization of bending and cutting.

[0062] End and reset stage: When the sheet metal bending is finished, the cutting ultrasonic wave 17 can continue cutting until the cutting of the entire sheet metal is completed. If the sheet metal is still in the bending process, the cutting ultrasonic wave 17 can stop after completing the cutting of the current part and reset through the electric push rod 16, waiting for the next suitable cutting time;

[0063] When the entire bending and cutting operation is completed, the spring potential energy of the curved spring rod 22 is released, and the elastic force of the spring pushes the relevant components, driving the slide rail seat 23 to reset, so that the entire synchronous docking assembly 2 is restored to the initial state, ready for the next processing operation;

[0064] In the traditional manual operation mode, when the bent sheet metal is transferred to the cutting position, it is difficult to ensure that the cutting saw blade of the cutting equipment can be accurately docked every time, which easily leads to cutting position deviation. However, the synchronous docking component 2 uses the linkage of the mechanical structure to enable the cutting ultrasonic wave 17 to follow the bending angle change of the sheet metal in real time, and always accurately cut the edge of the bent part, which effectively improves the accuracy of cutting and ensures the product quality. At the same time, the step of manually transferring the sheet metal is abandoned, and the simultaneous bending and cutting are realized, which greatly shortens the processing time.

[0065] like Figure 3 and Figure 5As shown, the synchronous docking plate 25 is provided with an adjustment component for adjusting different sizes of sheet metal parts, and the adjustment component includes: a notch 251, which is opened in the middle of the vertical end of the synchronous docking plate 25; a torsion rod 252, which is threadedly connected to the inside of the synchronous docking plate 25 and passes through the inner side of the notch 251, and the outer side of the torsion rod 252 is threadedly connected to a slider connected to the side wall of the notch 251 by a slide rail; a pointer plate 253, which is plugged and installed on the side of the slider away from the cutting ultrasonic wave 17; a telescopic plate 254, which is plugged and installed on the side of the slider close to the cutting ultrasonic wave 17, and the connecting frame 26 is connected to the side wall of the synchronous docking plate 25 by a slide rail, and the telescopic plate 254 and the connecting frame 26 are fixedly connected; a first dial 255, which is installed on one side of the vertical end of the synchronous docking plate 25 and is located below the pointer plate 253.

[0066] It should be noted that when the bent portion of the sheet metal passes through the bending seat 15 and contacts the horizontal end of the synchronous docking plate 25, in order to adapt to sheet metals of different sizes and accurately control the position of the cutting ultrasonic wave 17, the adjustment process begins. Specifically, by rotating the torsion rod 252, the slider moves along the slot 251, and the pointer plate 253 is plugged into the slider. As the slider moves, when the torsion rod 252 is rotated to make the pointer plate 253 reach the specified first scale plate 255 position, it indicates that the slider has moved to a position matching the size of the sheet metal. When the slider moves into place, the telescopic plate 254 drives the connecting frame 26 to slide along the synchronous docking plate 25, so that the cutting ultrasonic wave 17 on the connecting frame 26 moves to a precise position adapted to the size of the sheet metal, thereby achieving accurate adjustment of sheet metals of different sizes.

[0067] The torsion bar 252, slider, pointer plate 253, telescopic plate 254 and first scale plate 255 in the adjustment assembly cooperate with each other to accurately adjust the position of the cutting ultrasonic wave 17 according to sheet metal parts of different sizes. This allows the device to adapt to the processing of sheet metal parts of various sizes.

[0068] like Figure 3 , Figure 4 and Figure 6As shown, the control assembly 211 is arranged on the U-shaped frame 21, and is used to prevent the synchronous docking plate 25 from squeezing the sheet metal when resetting when the sheet metal bending is completed. A connecting block 2121 is installed on one of the vertical ends of the U-shaped frame 21. The control assembly 211 includes: a control disk 212, which is a circular structure, and the control disk 212 is fixedly connected to the front end of the connecting block 2121; a rotating groove 213, which is opened through the side of the control disk 212 away from the bending seat 15; an arc groove 214, which is opened below the control disk 212 and is connected to the rotating groove 213; a telescopic cylinder 215, which is rotatably connected to the axis of the control disk 212; an expansion spring rod 216, one end of which slides through the inner side of the telescopic cylinder 215; an extrusion piece 217, which is installed on the expansion spring rod The other end of 216, and one end of which passes through the inside of the rotating groove 213, and the side wall of the extrusion piece 217 is set as a bevel; the rotating block 218 is rotatably connected to the top of the control disk 212, and one side of the rotating block 218 is provided with a reset component for driving the rotating block 218 to reset; the connecting driving rod 2181, and its two ends are respectively fixedly connected to the rotating block 218 and the top of the slide rail seat 23; the control block 219 is plugged and installed on the rotating block 218 away from the axis of the control disk 212, and one end of the control block 219 slides through the inside of the rotating groove 213, and the end of the control block 219 close to the extrusion piece 217 is provided with a bevel, which is used for when the control block 219 rotates to the extrusion piece 217, the bevel can contact with the bevel of the extrusion piece 217 and produce extrusion, thereby controlling the movement of the control block 219.

[0069] It should be noted that when the sheet metal is being bent, as the bending proceeds, the slide seat 23 will move on the U-shaped frame 21, and the movement of the slide seat 23 will drive the rotating block 218 to rotate, thereby driving the control block 219 to rotate synchronously along the rotating groove 213. Before the bending is almost completed, the control block 219 rotates with the rotating block 218, and the inclined surface at one end of the control block 219 will contact and squeeze the inclined edge on the extrusion member 217. When the inclined surfaces of the two are in contact and extrusion, a force will be applied to the extrusion member 217, prompting the expansion spring rod 216 to retract inside the telescopic cylinder 215, thereby releasing the spring potential energy of the expansion spring rod 216. When the expansion spring rod 216 retracts and releases the potential energy, the control block 219 will be fixed at a specific position on the rotating groove 213. When the sheet metal is bent, the reset of the synchronous docking plate 25 is restricted, thereby ensuring that the synchronous docking plate 25 will not squeeze the bent part of the sheet metal during the reset process, thereby achieving the purpose of preventing damage to the bent sheet metal during discharge.

[0070] like Figure 4 and Figure 6As shown, a ratchet 2151 is installed below the telescopic cylinder 215, and a control frame 2152 is installed at the end of the ratchet 2151 facing away from the telescopic cylinder 215, and a pawl 2153 for resisting the ratchet 2151 is rotatably connected below the control frame 2152, and a compression spring 2154 is installed in the middle of the pawl 2153, and a rotating rod 2155 fixedly connected to the other end of the compression spring 2154 is rotatably connected to the bottom of the control frame 2152, and an extrusion torsion bar 2156 for extruding the control disk 212 is threadedly connected to the middle of the top of the control frame 2152.

[0071] It should be noted that when it is necessary to perform bending operations on the sheet metal at different angles and to adjust the angle of the telescopic cylinder 215 accordingly to adapt to this change, the control assembly 211 must be operated first. Specifically, by rotating the extrusion torsion bar 2156, the extrusion torsion bar 2156 will move along the thread direction, and one end of the extrusion torsion bar 2156 will gradually detach from the control disk 212, thereby releasing the extrusion restriction on the control disk 212, and the control frame 2152 can be rotated on the control disk 212, and the telescopic cylinder 215 is also moved. When the telescopic cylinder 215 rotates to a specified position, the compression spring 2154 on the rotating rod 2155 releases the spring potential energy, and the elastic force of the compression spring 2154 causes the pawl 2153 to tightly press against the gear teeth on the ratchet 2151, thereby locking the ratchet 2151 at the current position, thereby locking the angle of the telescopic cylinder 215, so that it remains at a position required to adapt to the bending angle of the sheet metal part. The present invention can accurately adjust the angle of the telescopic cylinder 215 according to different bending angle requirements of the sheet metal part;

[0072] like Figure 6 and Figure 7 As shown, a pointing plate 2191 is installed on the side of the control block 219 away from the axis of the control disk 212 , and a second scale plate 2192 is installed on the top of the control disk 212 and at the outer edge of the rotating groove 213 .

[0073] When the control block 219 rotates in the rotating groove 213, the pointing plate 2191 will move accordingly and point to the corresponding scale on the second dial 2192, so that the operator can clearly know the current angular position of the control block 219, which greatly improves the accuracy of angle adjustment compared to judging only by experience or feeling.

[0074] like Figure 4 As shown, the reset assembly includes: a reset frame 2193, which is fixedly connected to the reset frame 2193 on the side wall of the slide rail seat 23; a reset block 2194, which is connected to the reset frame 2193 on the side away from the slide rail seat 23 through the slide rail; a reset rod 2195, which is plugged and installed on the end of the reset block 2194 away from the control panel 212, and the reset rod 2195 is a U-shaped structure; a reset drive rod 2196, which is plugged and installed on the end of the reset rod 2195 away from the reset block 2194.

[0075] When the synchronous docking plate 25 restricts movement, the sheet metal has completed bending and cutting. At this time, the hydraulic press on the bending push frame 13 and the bending frame 12 begins to retract. During the retraction process of the bending push frame 13, its bending ball 14 will come into contact with the reset drive rod 2196. Since the bending ball 14 applies a force to the reset drive rod 2196, this force causes the reset block 2194 to slide on the reset frame 2193. When the reset block 2194 slides, the reset rod 2195 will drive the rotating block 218 to rotate, thereby driving the control block 219 to also rotate. The inner side of the movable groove 213 rotates, and at the same time, the curved spring rod 22 releases the spring potential energy. Under the action of the spring potential energy, the rotating block 218 can be driven to reset to the end of the rotating groove 213, so that the relevant components of the entire device are restored to the initial or preset state, and are ready for the next sheet metal bending and cutting operation. With the cooperation of the reset component, after the sheet metal processing is completed, the reset action can be automatically triggered, and the synchronous docking plate 25 can be reset to the appropriate position without manual intervention, which greatly improves the degree of automation of the equipment.

[0076] like Figure 8-Figure 9 As shown, a first rack plate 221 is installed on the side of the bending frame 12 located on the left side and away from the bending ball 14, a fixing frame 222 is installed on the top of the processing table 1 and below the first rack plate 221, and a transmission gear 223 is rotatably connected to the side wall of the fixing frame 222. A second rack plate 224 is connected to the top of the processing table 1 and below the transmission gear 223 through a slide rail, and the transmission gear 223 is meshed between the first rack plate 221 and the second rack plate 224, and a driving plate 225 is installed on the end of the second rack plate 224 away from the bending ball 14.

[0077] It should be noted that, after the sheet metal part is bent and cut, the hydraulic press starts to drive the bending frame 12 to reset. Since the first rack plate 221 is installed on the bending frame 12, when the bending frame 12 is reset with the drive of the hydraulic press, it will drive the first rack plate 221 to move synchronously. The movement of the first rack plate 221 will drive the transmission gear 223 to rotate in the opposite direction. When the transmission gear 223 rotates in the opposite direction, it will further drive the second rack plate 224 to move along the slide rail. At this time, the second rack plate 224 drives the drive plate 225 to move synchronously, and the drive plate 225 will move along the bent The bent plate moves, and a certain external force is applied to cause the bent sheet metal to detach from the synchronous docking plate 25. This is because after the side of the sheet metal is bent, its own shape changes, making it difficult to detach directly from the processing table 1 on the synchronous docking plate 25. The pushing action of the drive plate 225 just solves this problem, making it convenient to take out the processed sheet metal later. Through the automated pushing action of the drive plate 225, the bent sheet metal can be easily detached from the synchronous docking plate 25, greatly facilitating the later taking-up operation of the processed sheet metal and improving work efficiency.

[0078] It is worth noting that the top end of the driving plate 225 does not contact the bottom end of the synchronous docking plate 25, and when the sheet metal is against the synchronous docking plate 25, the lower half of the sheet metal extends out from under the synchronous docking plate 25, so that the driving plate 225 can drive the sheet metal and detach from the synchronous docking plate 25.

[0079] The working principle of the present invention is: the equipment is used for side bending and cutting of sheet metal parts. When in use, the sheet metal part passes vertically between the two bending frames 12 on the processing table 1, and the part to be bent is extended on the bending seat 15. Then, the bending frame 12 is pushed by the hydraulic press to fix the sheet metal part. The adjusting rod 24 is adjusted to drive the synchronous docking plate 25 to move so that its horizontal end contacts the end of the sheet metal part, and ensures that the top end of the sheet metal part corresponds to the cutting ultrasonic wave 17. In preparation for subsequent operations, the hydraulic press is started to drive the bending push frame 13 to move, and the bending ball 14 moves along the sheet metal part to perform the bending operation. During this process, the sheet metal is squeezed against the vertical end of the synchronous docking plate 25, so that the synchronous docking plate 25 and the slide rail seat 23 slide along the U-shaped frame 21 to adapt to the change in the bending angle, and at the same time, the electric push rod 16 is started to drive the cutting ultrasonic wave 17 to move downward. As the synchronous docking plate 25 moves, the cutting ultrasonic wave 17 can cut the edge of the bent part of the sheet metal, so as to achieve synchronization of bending and cutting. After the bending and cutting of the sheet metal are completed, if the bending is completed, the cutting ultrasonic wave 17 completes the remaining cutting; if it is still in the process of bending and the cutting part has been completed, the cutting ultrasonic wave 17 stops waiting, releases the spring potential energy of the curved spring rod 22, pushes the relevant components to reset the slide rail seat 23, and restores the synchronous docking plate 25 and the like to the initial state, ready for the next processing;

[0080] By rotating the torsion rod 252 of the adjustment assembly on the synchronous docking plate 25, the slider moves along the notch 251. When the pointer plate 253 reaches the position specified by the first dial 255, the telescopic plate 254 drives the connecting frame 26 to slide, so that the cutting ultrasonic wave 17 moves to the precise position adapted to the size of the sheet metal part, thereby achieving the adjustment of sheet metal parts of different sizes.

[0081] During the bending process, the slide rail seat 23 moves to drive the rotating block 218 and the control block 219 to rotate. When the bending is almost finished, the inclined surface of the control block 219 contacts and squeezes the inclined edge of the extrusion member 217, causing the expansion spring rod 216 to retract and release potential energy, so that the control block 219 is fixed, limiting the extrusion of the bent sheet metal when the synchronous docking plate 25 is reset;

[0082] After the sheet metal parts are processed, the bending push frame 13 and the hydraulic press on the bending frame 12 retract, and the bending ball 14 contacts the reset driving rod 2196, causing the reset block 2194 to slide, and the reset rod 2195 drives the rotating block 218 to rotate. At the same time, the curved spring rod 22 releases potential energy, so that the rotating block 218 is reset to the end of the rotating groove 213, realizing automatic reset and improving the automation degree of the equipment;

[0083] When the hydraulic press drives the bending frame 12 to reset, the first rack plate 221 installed on one side thereof moves, and is driven by the transmission gear 223 to drive the second rack plate 224 and the driving plate 225 to move. The driving plate 225 moves along the bent sheet metal, and an external force is applied to separate it from the synchronous docking plate 25, so as to facilitate the removal of the processed sheet metal.
