Description

Technical Field

[0001] This utility model relates to the technical field of bending machines, and in particular to an anti-deviation material support device for bending machines. Background Technology

[0002] A bending machine is a machine that can bend thin plates, making it convenient to quickly bend thin plates and other parts according to user needs. It is commonly used in industrial production.

[0003] A search revealed a patent on the Chinese Patent Network (publication number: CN221952164U) for an anti-deviation material support device for a bending machine. The device includes a material support frame with two fixed plates fixedly mounted on its top. Limiting rods are fixedly mounted on one side of the outer wall of each of the two fixed plates. Connecting columns are movably sleeved on the outer walls of each of the two limiting rods. A bending machine body is fixedly mounted on one side of the outer wall of the material support frame, and the outer walls of the two limiting rods are fixedly connected to the opposite side of the outer wall of the bending machine body. A placement plate is fixedly mounted between the tops of the two connecting columns. Two L-shaped frames are fixedly mounted on the top of the placement plate, and electric push rods are fixedly mounted on the bottom inner walls of each of the two L-shaped frames. First, the forward and reverse motors 12 are started according to the size of the material to be bent. Under the action of the sliding groove 16, the sliding block 15 moves stably on the reciprocating screw 14. Then, the placement plate 6 is installed on the sliding block 15. Because the placement plate 6 is relatively long and the two connecting columns 4 installed at the bottom of the placement plate 6 are movably sleeved on the two limiting rods 3, the placement plate 6 moves back and forth stably. After moving to the appropriate position, the metal material is placed on the placement plate 6. Then, the two electric push rods 8 are started, which drive the two limiting pressure plates 9 to move downward, limiting the metal material on the placement plate 6. Then, the bending component 10 on the bending machine body 5 performs the bending operation. After one operation, the placement plate 6 can be moved forward by the sliding block 15 for a second bending. In general, the operator does not need to hold the metal material with their hands to perform the bending operation, which reduces the operator's fatigue and prevents the metal material from shifting position during bending, thus improving the pass rate of bending the metal material and improving the effectiveness of the anti-deviation material support device of the bending machine.

[0004] This application uses a placement plate to move materials into the bending machine for bending, eliminating the need for manual material handling and reducing worker fatigue. While this method has some practical benefits, it still has certain drawbacks. For example, during loading, workers still need to manually place the material onto the placement plate, align it with the bending point of the machine, and then activate the electric push rod to lower the two limit plates to compress the material before bending. This loading method requires manual operation, and manually aligning the material under the two limit plates takes time, thus reducing bending efficiency and increasing worker fatigue. Therefore, this method has room for improvement. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-deviation material support device for a bending machine, so as to solve the problem mentioned in the background art that the existing bending machine material support devices require manual feeding by workers when bending materials, and the alignment is difficult, which directly affects the bending efficiency of materials and increases the labor intensity of workers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-deviation material support device for a bending machine, comprising a base, a positioning platform fixedly connected to the upper surface of the base, a material support component slidably connected to the upper surface of the positioning platform, and an automatic feeding component fixedly connected to the upper surface of the positioning platform.

[0007] The material support assembly includes a clamping mechanism and a moving mechanism. The clamping mechanism is used to clamp and lock the parts, and the moving mechanism is used to move the parts to the bending position of the bending machine. The automatic feeding assembly is used to perform automated feeding operations on the material support assembly.

[0008] Preferably, the clamping mechanism includes a material support plate, which is slidably connected to the upper surface of the positioning table. Two telescopic cylinders are fixedly connected to the upper surface of the material support plate. The output ends of the two telescopic cylinders are fixedly connected to lateral clamping plates. The opposing surfaces of the two lateral clamping plates are fixedly connected to upper pressure plates. The two telescopic cylinders can drive the two lateral clamping plates to move closer to each other, thereby clamping the material on both sides. The two upper pressure plates can restrict the upper position of the material to ensure that the material does not warp during the bending process.

[0009] Preferably, the moving mechanism includes a servo motor, which is fixedly connected to the left side of the positioning table. The output end of the servo motor is fixedly connected to a connecting shaft, and the output end of the servo motor is fixedly connected to the connecting shaft through a coupling. A strip groove is formed on the upper surface of the positioning table. The end of the connecting shaft away from the servo motor extends into the interior of the strip groove and is fixedly connected to a transmission gear. A rack plate is fixedly connected to the lower surface of the material support plate. After the servo motor is started, it can drive the transmission gear to rotate through the connecting shaft, thereby driving the material support plate to move back and forth as a whole through the rack plate.

[0010] Preferably, the rack plate meshes with the transmission gear, and the upper surface of the positioning platform has two limiting grooves. The inner walls of the two limiting grooves are fixedly connected to limiting rods, and the inner walls of the limiting grooves are slidably connected to limiting blocks. The two limiting blocks are slidably connected to the surfaces of the two limiting rods, and the upper surfaces of the two limiting blocks are fixedly connected to the lower surface of the material support plate. During the back-and-forth movement of the material support plate, the two limiting blocks can be driven to slide on the surfaces of the two limiting grooves and the limiting rods, thus locking the position of the material support plate and ensuring the stability of the material support plate during movement.

[0011] Preferably, the automatic feeding component includes a feeding frame with a through hole on its side, the position of which corresponds to the position of the material support plate. The upper surface of the feeding frame has a strip-shaped feeding hole, the position of which corresponds to the position of the two side clamps. The material can be stored and stacked through the strip-shaped feeding hole, which facilitates automatic feeding by its own gravity, eliminating the need for manual feeding by staff.

[0012] Preferably, hydraulic cylinders are fixedly connected to both the left and right sides of the feeding frame, and rectangular grooves are opened on the left and right inner walls of the strip-shaped feeding hole. Extrusion plates are slidably connected to the inner walls of the rectangular grooves, and the output ends of the two hydraulic cylinders extend into the interior of the two rectangular grooves and are fixedly connected to the two extrusion plates. A pushing mechanism is fixedly connected to the back of the positioning table. The two hydraulic cylinders can drive the two extrusion plates to move closer to each other in the strip-shaped feeding hole, thereby squeezing the upper layer of material at the bottom and restricting the stacked material on the upper layer to avoid affecting the movement of the material at the bottom.

[0013] Preferably, the pushing mechanism includes a right-angle frame, an electric push rod is fixedly connected to the upper surface of the right-angle frame, and a pushing plate is fixedly connected to the output end of the electric push rod. The position of the pushing plate corresponds to the position of the through hole. The electric push rod can drive the pushing plate to move forward so as to push the material forward through the through hole, which facilitates pushing the material out of the support plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This anti-deviation material support device for a bending machine, through the coordinated arrangement of a material support component and an automatic feeding component, allows for the storage and stacking of materials using the strip-shaped feeding hole at the top of the feeding frame. During feeding, the material moves downwards due to its own gravity to complete the feeding operation. The material rests on the material support plate and is clamped by the side clamping plate and the upper pressure plate. Simultaneously, the transmission gear and rack plate work together to move the material support plate and the material forward into the bending machine, thereby achieving automatic feeding and bending of materials. The entire process requires no manual operation by the operator, greatly improving the bending efficiency of materials and reducing the labor intensity of the workers.

[0016] 2. This anti-deviation material support device for a bending machine, through the setting of a hydraulic cylinder, an extrusion plate, an electric push rod and a pusher plate, can restrict other materials stacked above the bottom material in the strip feeding hole during use, so as to avoid them affecting the movement of the bottom material. At the same time, the pusher plate can drive the material forward, making it easy to move the material forward and extend to the front end of the support plate, thereby enabling bending processing of the material at different positions, with high flexibility.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] Example 1: A material support device for preventing deviation of a bending machine includes a base 1, a positioning platform 2 fixedly connected to the upper surface of the base 1, a material support component 3 slidably connected to the upper surface of the positioning platform 2, and an automatic feeding component 4 fixedly connected to the upper surface of the positioning platform 2.

[0025] The material support assembly 3 includes a clamping mechanism 31 and a moving mechanism 32. The clamping mechanism 31 is used to clamp and lock the parts, and the moving mechanism 32 is used to move the parts to the bending position of the bending machine. The automatic feeding assembly 4 is used to perform automatic feeding operation on the material support assembly 3.

[0026] Furthermore, the clamping mechanism 31 includes a material support plate 3101, which is slidably connected to the upper surface of the positioning table 2. Two telescopic cylinders 3102 are fixedly connected to the upper surface of the material support plate 3101. The output ends of the two telescopic cylinders 3102 are fixedly connected to side clamping plates 3103, and the opposite surfaces of the two side clamping plates 3103 are fixedly connected to upper pressure plates 3104.

[0027] Furthermore, the active mechanism 32 includes a servo motor 3201, which is fixedly connected to the left side of the positioning platform 2. The output end of the servo motor 3201 is fixedly connected to a connecting shaft 3202. A strip groove is formed on the upper surface of the positioning platform 2. The end of the connecting shaft 3202 away from the servo motor 3201 extends into the interior of the strip groove and is fixedly connected to a transmission gear 3203. A rack plate 3204 is fixedly connected to the lower surface of the material support plate 3101. The rack plate 3204 meshes with the transmission gear 3203. Two limiting grooves are formed on the upper surface of the positioning platform 2. Limiting rods 3205 are fixedly connected to the inner walls of the two limiting grooves. Limiting blocks 3206 are slidably connected to the inner walls of the limiting grooves. The two limiting blocks 3206 are slidably connected to the surfaces of the two limiting rods 3205 respectively. The upper surfaces of the two limiting blocks 3206 are fixedly connected to the lower surface of the material support plate 3101.

[0028] The material rests on the support plate 3101 and is clamped on both sides by the two side clamping plates 3103. The top is restricted by the two upper pressure plates 3104, which ensures the clamping effect on the material and does not affect the bending effect. In addition, after the servo motor 3201 is started, it can drive the transmission gear 3203 to rotate through the connecting shaft 3202. The transmission gear 3203 then drives the support plate 3101 to move forward through the rack plate 3204, thereby changing the position of the material through the support plate 3101. This facilitates bending operations at different positions of the material and provides high flexibility.

[0029] Example 2: The automatic feeding assembly 4 includes a feeding frame 401. A through hole 402 is provided on the side of the feeding frame 401, the position of which corresponds to the position of the material support plate 3101. A strip-shaped feeding hole 403 is provided on the upper surface of the feeding frame 401, the position of which corresponds to the position of the two side clamping plates 3103. Hydraulic cylinders 404 are fixedly connected to both sides of the feeding frame 401. Rectangular grooves are provided on the left and right inner walls of the strip-shaped feeding hole 403. The inner wall of the rectangular groove is slidably connected to the extrusion plate 405, and the output ends of the two hydraulic cylinders 404 extend into the interior of the two rectangular grooves and are fixedly connected to the two extrusion plates 405. The back of the positioning table 2 is fixedly connected to the pushing mechanism, which includes a right-angle frame 406. The upper surface of the right-angle frame 406 is fixedly connected to the electric push rod 407. The output end of the electric push rod 407 is fixedly connected to the pushing plate 408. The position of the pushing plate 408 corresponds to the position of the through hole 402.

[0030] Materials enter through the strip feeding hole 403, are stacked inside the strip feeding hole 403, and the bottom material rests on the support plate 3101. During normal operation, two hydraulic cylinders 404 can drive two extrusion plates 405 to move closer to each other. The two extrusion plates 405 can clamp the material above the bottom material on both sides, ensuring that the material stacked on top will not affect the movement of the bottom material. At this time, the electric push rod 407 can drive the push plate 408 to move forward. The push plate 408 can drive the bottom material to move forward, thereby extending the support plate 3101 to facilitate bending of the material. The entire process does not require manual operation by the staff, which greatly improves the bending efficiency of the material.

[0031] It should be noted that the material will not shift within the strip feeding hole 403 due to the confinement of the space inside the hole. In addition, the through hole 402 at the bottom can also confine the material to prevent it from shifting and affecting the bending effect.

[0032] Working principle: First, the material to be bent is placed into the strip feeding hole 403. The material is stacked in the strip feeding hole 403, with the bottom material contacting the top of the support plate 3101. Due to the restriction of the strip feeding hole 403, the material will not shift or shake inside. At this time, the two hydraulic cylinders 404 are opened, which can drive the two extrusion plates 405 to move closer together. The two extrusion plates 405 can clamp the material above the bottom material on both sides, thus preventing the material above from affecting the movement of the bottom material. At this time, the electric push rod 407 is activated, which can drive the push plate 408 to move forward. The push plate 408 can drive the bottom material to move forward on the support plate 3101 until the material extends out of the front end of the support plate 3101. At this time, the two telescopic cylinders 3102 Upon startup, the two telescopic cylinders 3102 drive the two side clamping plates 3103 to move closer together until the material is clamped on both sides. At the same time, the two upper pressure plates 3104 press the material down from top to bottom. At this time, the material is fixed in position on the support plate 3101. Simultaneously, the servo motor 3201 starts and drives the transmission gear 3203 to rotate through the connecting shaft 3202. This drives the rack plate 3204 to move forward, which in turn drives the support plate 3101 to move forward. This allows the material to be pushed deeper into the bending area of ​​the bending machine, facilitating the bending operation. After bending, the operator only needs to manually unload the material, eliminating the need for loading. This greatly improves the bending efficiency of the material and reduces the labor intensity of the operator.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
