Description

Technical Field

[0001] This utility model belongs to the technical field of punching equipment, and in particular relates to a flying punch mechanism for a continuous punching machine. Background Technology

[0002] In the production process of light steel keel, punching equipment is mainly used to process holes (such as mounting holes, wire holes, connection holes, etc.) on the surface of the keel or at specific locations to meet the needs of building installation. The flying punch mechanism is the main mechanism used for punching on the punching machine. It is generally installed at the rear end of the cold bending machine and is used for punching and cutting in the production process of light steel keel. Compared with the punching and cutting mechanism using hydraulic cylinders or saw blade cutting mechanism, the flying punch mechanism does not require an additional lead screw mechanism, has a simple structure, occupies little space, has high synchronization with the keel movement during punching and cutting, and has high punching accuracy.

[0003] However, it still has the following drawbacks in practical use:

[0004] The existing continuous punching machine's flying punch mechanism requires manual lubrication during use, which is time-consuming, labor-intensive, and inefficient. In addition, the spindle's operation is affected by eccentric weight, which can cause instability.

[0005] 2. Existing continuous punching machines with fly-punching mechanisms have limited applicability because the die size is fixed and the punching or cutting depth cannot be adjusted according to actual usage requirements. Therefore, we provide a fly-punching mechanism for a continuous punching machine to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a flying punch mechanism for a continuous punching machine. By setting a main shaft assembly, an eccentric block, and a tapered lubricating nozzle installed on the outside of the mounting base, it is convenient to add lubricating oil. At the same time, a counterweight plate is installed on the drive shaft, and three M10 threaded holes are reserved on the counterweight plate. Additional counterweight can be added during the debugging of the flying punch mechanism to balance the eccentric weight of the main shaft assembly, reduce the starting torque of the servo motor, and make the main shaft assembly run more smoothly. It also forms a flywheel-like structure that can store energy during continuous operation. In addition, by using an adjustment component, the central cylinder of the pressure rod and the fixed base adopt a clearance fit. By placing a certain number of circular thin iron plates at the lower end of the pressure rod, the height of the rod can be adjusted, thereby adjusting the punching or cutting depth of the die. It has a wide range of applications.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a flying punch mechanism for a continuous punching machine, including a base and a frame installed on the rear end of its upper surface. X-direction linear guides are installed on both the front and rear ends of the upper surface of the base. A slide plate is slidably installed above the X-direction linear guides. A mold is installed on the slide plate. A main shaft assembly is set in front of the frame. An adjustment assembly is set on the top of the mold.

[0009] The spindle assembly includes a rotating plate located in front of the frame and a counterweight plate mounted on top of the rotating plate. The front end face of the counterweight plate has a reserved screw hole.

[0010] The adjustment assembly includes a mounting base bolted to the top of the mold, and a pressure bar embedded inside the mounting base.

[0011] The present invention is further configured such that a mounting base is provided at the top of the inner side of the frame, and a servo motor is installed above the rear end face of the frame.

[0012] The present invention is further configured such that a reducer is installed on the output shaft of the servo motor, and a guide frame is installed on the front end of the upper surface of the slide plate.

[0013] The present invention is further configured such that a Y-axis linear guide rail is installed on the top of the rear end face of the guide frame, and a slide block is slidably installed on the outer wall of the Y-axis linear guide rail.

[0014] The present invention is further configured such that an eccentric block is installed below the front end face of the rotating plate, and an mounting plate is provided on the front end face of the eccentric block, and the front end face of the mounting plate is connected to the slide by bolts.

[0015] The present invention is further configured such that a conical lubricating oil nozzle is provided on the top of both the eccentric block and the mounting base, and a drive shaft is installed at the center of the rear end face of the rotating plate. The other end of the drive shaft passes through the bearing on the mounting base and is connected to the output shaft of the reducer through a coupling.

[0016] The present invention is further configured such that the cross-section of the fixing seat and the pressure rod is T-shaped, and the bottom of the pressure rod is filled with a thin iron plate.

[0017] This utility model has the following beneficial effects:

[0018] This invention solves the problems of manual lubrication, time-consuming and labor-intensive operation, low efficiency, and unstable operation of the spindle due to eccentric weight in existing continuous punching machines. A counterweight plate is installed on the drive shaft of the fly-punching mechanism to balance the eccentric weight of the spindle assembly, reduce the starting torque of the servo motor, and make the spindle assembly run more smoothly. It also forms a flywheel-like structure that can store energy during continuous operation. Three M10 threaded holes are pre-drilled on the counterweight plate to allow for the addition of extra counterweight during the fly-punching mechanism's debugging process. This invention addresses the problems of manual lubrication, time-consuming and labor-intensive operation, low efficiency, and unstable operation of the spindle due to eccentric weight in existing continuous punching machines.

[0019] This utility model, by setting an adjustment component, uses a clearance fit between the central cylinder of the pressure rod and the fixed seat. By placing a certain number of circular thin iron plates at the lower end of the pressure rod, the height of the rod can be adjusted, thereby adjusting the depth of punching or cutting of the die. It has a wide range of applications and solves the problem that the existing continuous punching machine's flying punch mechanism cannot adjust the depth of punching or cutting according to actual usage needs due to the fixed size of the die, resulting in a limited range of applications.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Please see Figures 1 to 4 This utility model is a flying punch mechanism for a continuous punching machine, including a base 100 and a frame 103 installed on the rear end of its upper surface. X-direction linear guide rails 101 are installed on both the front and rear ends of the upper surface of the base 100. A slide plate 102 is slidably installed above the X-direction linear guide rails 101. A mold 102a is installed on the slide plate 102. A spindle assembly 200 is provided in front of the frame 103. The spindle assembly 200 includes a rotating plate 201 provided in front of the frame 103 and a counterweight plate 202 installed on the top of the rotating plate 201. A reserved screw hole 202a is provided on the front end face of the counterweight plate 202.

[0031] Specifically, a mounting base 103a is provided at the top of the interior of the frame 103, and a servo motor 104 is installed above the rear end face of the frame 103; a reducer 104a is installed on the output shaft of the servo motor 104, and a guide frame 105 is installed at the front end of the upper surface of the slide plate 102; a Y-axis linear guide rail 105a is installed at the top of the rear end face of the guide frame 105, and a slide block 106 is slidably installed on the outer wall of the Y-axis linear guide rail 105a; an eccentric block 203 is installed below the front end face of the rotating plate 201, and a mounting plate 204 is provided on the front end face of the eccentric block 203, and the front end face of the mounting plate 204 is connected to the slide block 106 by bolts; a conical lubricating nozzle 203a is provided on the top of both the eccentric block 203 and the mounting base 103a, and a drive shaft 205 is installed at the center of the rear end face of the rotating plate 201, and the other end of the drive shaft 205 passes through the bearing on the mounting base 103a and is connected to the output shaft of the reducer 104a through a coupling.

[0032] Furthermore, the mold 102a, guide frame 105, etc., move along the X-direction linear guide rail 101 under the action of the slide plate 102, and the slide block 106 and the structure installed on it move up and down along the Y-direction linear guide rail 105a. The servo motor 104, reducer 104a, mold 102a, etc. are all existing technologies, so they will not be described in detail here. The weight of the counterweight plate 202 is increased by adding an external structure through the reserved screw hole 202a to ensure the stability of the spindle assembly 200 during operation.

[0033] The operation process of this embodiment is as follows: the servo motor 104 drives the reducer 104a to rotate, and the output shaft of the reducer 104a drives the transmission shaft 205 to rotate. Because the eccentric block 203 is not concentric with the transmission shaft 205, the eccentric block 203 will make circular motion around the output shaft of the reducer 104a. The main shaft assembly 200 is connected to the slide 106 of the Y-axis linear guide rail 105a through the mounting plate 204, which restricts the eccentric block 203 from rotating around its own axis. At the same time, because the guide rail assembly and the slide plate 102 are connected together, the eccentricity... When block 203 performs circular motion, it will drive the mold 102a on the slide plate 102 to move horizontally on the X-direction linear guide rail 101 via the guide component. The complete cycle of each punching or cutting is as follows: Assuming that the eccentric block 203 is at the highest point, the transmission shaft 205 starts to rotate under the drive of the servo motor 104, causing the eccentric block 203 to rotate clockwise. When it is about to reach the lowest point, the lower end of the eccentric block 203 begins to press against the upper end of the mold 102a. When it reaches the lowest point, the punching or cutting of the keel is achieved. When the eccentric block 203 exceeds... After reaching its lowest point, the pressure gradually increases, reducing the compression on the mold 102a. As the servo motor 104 rotates, the eccentric block 203 reaches its highest point again, forming a complete cycle. During the operation of the flying punch mechanism, the horizontal tangential speed of the eccentric block 203 must be equal to the conveying speed of the keel to ensure the synchronization between the mold 102a and the keel, preventing the keel from getting stuck. This also ensures the accuracy of the hole spacing. Therefore, the eccentricity of the drive shaft 205 must be adapted to the linear speed of the keel. The eccentric block 203 and the mounting base 103a are both on the side. The opening leads directly to the cylindrical roller bearing inside, and a tapered lubrication nozzle 203a is installed on the outside for easy lubrication. A counterweight plate 202 is installed on the drive shaft 205 of the fly-jet mechanism, mainly to balance the eccentric weight of the spindle assembly 200, reduce the starting torque of the servo motor 104, and make the spindle assembly 200 run more smoothly. At the same time, it forms a flywheel-like structure that can store energy during continuous operation. The counterweight plate 202 also has three M10 threaded holes reserved, which can add additional counterweights during the debugging of the fly-jet mechanism.

[0034] Example 2

[0035] Please see Figure 1 and Figure 5 Based on Embodiment 1, unlike the first embodiment, an adjustment component 300 is provided. The adjustment component 300 includes a fixed seat 301 that is bolted to the top of the mold 102a, and a pressure rod 302 embedded in the upper part of the fixed seat 301. This solves the problem that the existing continuous punching machine's flying punch mechanism cannot adjust the punching or cutting depth according to actual usage needs due to the fixed size of the mold, resulting in a limited range of applications.

[0036] Specifically, the cross-sections of the fixing base 301 and the pressure rod 302 are T-shaped, and the bottom of the pressure rod 302 is filled with a thin iron plate 303.

[0037] Furthermore, the center of the fixing seat 301 is provided with an opening, the pressure rod 302 is installed at the center of the fixing seat 301 with a gap, and the thickness of the thin iron plate 303 is 0.5mm to adjust the depth of punching and cutting.

[0038] The operation process of this embodiment is as follows: A pressure rod 302 and a fixing seat 301 are installed on the upper end of the mold 102a. The pressure rod 302 and the fixing seat 301 are fixed to the upper plate of the mold 102a with four screws. The central cylinder of the pressure rod 302 and the fixing seat 301 are fitted with a clearance. The height of the rod can be adjusted by placing a certain number of circular thin iron plates 303 (thickness 0.5mm) at the lower end of the pressure rod 302, thereby adjusting the depth of punching or cutting of the mold 102a.
