Description

Technical Field

[0001] The invention relates to the technical field of screw manufacturing and processing, and in particular to an intelligent numerically controlled heading machine. Background Art

[0002] The heading machine is a cold heading equipment, mainly used for the head forming of screw products. Its working principle is to straighten the wire, feed the wire, cut it, feed it into the main die, punch it for initial forging, and punch it for the blank to be formed. The traditional one-die two-punch heading machine is generally driven by only one power mechanism, for example, an AC asynchronous motor drives the crankshaft through a V-belt and large and small pulleys to provide the impact running platform with motion stroke and forming impact force; at the same time, the crankshaft generates a second axis through gear transmission, and through a complex cam mechanism, connecting rod mechanism, ratchet mechanism and disc mechanism, it provides power source for the upper and lower platforms, shearing and feeding mechanism, wire feeding mechanism and ejection mechanism of the one-die two-punch heading machine, and also controls the dynamic curve of the relationship between the above four components and the main motion position of the crankshaft - the mechanical cam connecting rod motion control curve. These mechanisms contain a large number of moving pairs and rotating pairs; every change in variety and adjustment of the length of the production screws is a complex physical and technical work. Each mechanism is driven by a complex connecting rod cam transmission assembly, so every change in screw variety and adjustment of the machine length for production screws is a complex physical and technical work, and during the machine adjustment and line change operation, the operator may face safety hazards.

[0003] For example, when it is necessary to adjust the production of M6 screws with a length of 50mm to that of M6 screws with a length of 35mm, for the traditional one-die two-punch heading machine, the mechanical cam motion curves of these two screw lengths are different. This requires using a mechanical wrench to adjust the spring seat on the connecting rod mechanism in the upper and lower walkway mechanism, the length of the connecting rod screw in the shear feeding mechanism, and especially the adjustment of the faceplate in the wire feeding mechanism and the ejection mechanism to adapt to the start and end time of the coordination of the mechanical cam movement due to the length change. The above adjustment only has directional guidance, but no digital help. It is necessary to repeatedly adjust each mechanical cam mechanism, and to use the debugged products to repeatedly measure before the machine adjustment work can be finally completed. Most of the current heading machines do not have variable frequency speed regulation, and they all check whether the slow motion of the mechanical cam movement is appropriate under inching, but the forming of the screw head must be repeatedly tested at high speed, and safety accidents of the debugging workers' press hands occur from time to time. Summary of the invention

[0004] In view of this, the present invention provides an intelligent CNC heading machine to solve the above problems.

[0005] An intelligent CNC heading machine. It includes a platform body, an impact platform assembly, an upper and lower platform assembly, a shearing and feeding assembly, a wire feeding assembly, an ejection assembly, and five drive assemblies. The impact platform assembly includes a crankshaft and an impact platform. The upper and lower platform assembly includes a dual-rod shaft. The wire feeding assembly includes a main guide wheel. The drive assembly is mainly composed of a servo motor and a reducer, and the five servo motors are respectively a first servo motor connected to one side of the impact platform assembly, a second servo motor connected to one side of the upper and lower platform assembly, a third servo motor connected to one side of the shearing and feeding assembly, a fourth servo motor connected to one side of the wire feeding assembly, and a fifth servo motor connected to one side of the ejection assembly. The first servo motor drives the crankshaft to rotate, and the crankshaft drives the impact platform to perform periodic reciprocating motion, and provides the motion coordinate axis of the electronic cam motion control curve for the intelligent CNC heading machine. The second servo motor, the third servo motor, the fourth servo motor, and the fifth servo motor follow the coordinate axis of the electronic cam motion control curve provided by the first servo motor. The second servo motor drives the dual-rod shaft to intermittently swing and provides high-precision position control motion for the upper and lower platform assemblies. The third servo motor realizes the reciprocating motion of shearing and feeding through gears and racks or a reciprocating device. The fourth servo motor controls the rotation angle of the main wheel and controls the feeding length of the steel wire. The fifth servo motor realizes the reciprocating motion of the ejector rod and the ejection length through gears and racks or a reciprocating device.

[0006] Furthermore, the wire feeding assembly also includes a feeding sensor arranged on one side of the shear feeding assembly for feeding back the blocking distance to the PLC control program.

[0007] Furthermore, the ejection assembly further comprises an ejection sensor disposed on one side of the ejection rod and used for feeding back the position of the ejection rod to the PLC control program in real time.

[0008] Furthermore, the second servo motor adopts a torque control mode to perform electronic cam following motion.

[0009] Furthermore, the third servo motor, the fourth servo motor, and the fifth servo motor perform electronic cam following motion in a position control mode.

[0010] Furthermore, the intelligent CNC heading machine establishes a coordinate system for the electronic cam movement through the rotation angle of the output end of the first servo motor and the movement distance of the impact treadmill, and establishes a coordinate system for the electronic cam following movement of the second servo motor, the third servo motor, the fourth servo motor, and the fifth servo motor.

[0011] Furthermore, a "Intelligent CNC Heading Machine Electronic Cam Control Coordinate Parameter Curve" is drawn based on the position coordinate relationship between the control movements of the second servo motor, the third servo motor, the fourth servo motor, and the fifth servo motor and the control movement of the first servo motor.

[0012] Furthermore, the electrical control system of the intelligent CNC heading machine is composed of a PLC control program and a computer control screen, etc. The PLC control program is organized and compiled based on the "Intelligent CNC Heading Machine Electronic Cam Control Coordinate Parameter Curve".

[0013] Furthermore, the PLC control program includes settings of variable parameters and fixed quantity parameters in the control program, and mathematical calculation methods and formulas in the control program.

[0014] Compared with the prior art, the intelligent CNC heading machine provided by the present invention drives the operation of each component through the first servo motor, the second servo motor, the third servo motor, the fourth servo motor, and the fifth servo motor, so that the power between these components is independent of each other, thus avoiding the complex connecting rod mechanism, cam mechanism, etc. driven by a power source, and greatly reducing the vibration and noise caused by the mechanical cam movement. The intelligent CNC heading machine sets the control parameters of standard integers such as 50mm, 45mm, 40mm, 35mm, 30mm... in the formula table when it leaves the factory, and the debugger can easily change it from 50mm to 35mm according to the required product length. The debugger only needs to call out the formula and use a wrench to adjust the stopper assembly and the ejection assembly to the values ​​specified by the two laser position sensors to complete the machine adjustment work, which is fast and safe. If the non-integer M6 length of 36mm is produced, the intelligent CNC heading machine provided by the present invention can adjust the parameters on the control screen according to the length of the screw, and use the slow motion of the servo motor to see whether the electronic cam motion curve is appropriate, so as to produce the first M6*36 screw before the high-speed motion and safe production change. The intelligent CNC heading machine transforms the complicated machine adjustment work from manual labor, mechanical motion adjustment and empiricism into digital screen operation, realizing the economical production mode of multi-variety large, medium and small batch products.

DETAILED DESCRIPTION

[0022] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0023] like Figure 1As shown, it is a schematic diagram of the structure of the intelligent CNC heading machine provided by the present invention. The intelligent CNC heading machine includes a platform 10, a wire feeding assembly 20 arranged on the platform 10, a shearing and feeding assembly 30 arranged on one side of the wire feeding assembly 20, an upper and lower platform assembly 40 arranged on one side of the shearing and feeding assembly 30, an impact platform assembly 50 arranged on one side of the upper and lower platform assembly 40, and an ejection assembly 60 arranged on one side of the shearing and feeding assembly 30. It can be imagined that the intelligent CNC heading machine also includes some other functional modules, such as a power module, a computer module, etc., which are technologies already known to those skilled in the art and will not be described one by one here.

[0024] It should be noted that the intelligent CNC heading machine replaces the complex mechanical cam drive to control the operation of each component through five driving components 70, so as to perform the screw heading operation. The driving component 70 is mainly composed of a servo motor and a reducer, and the five servo motors are respectively a first servo motor 71 connected to one side of the impact running platform component 50, a second servo motor 72 connected to one side of the upper and lower walking platform component 40, a third servo motor 73 connected to one side of the shear feeding component 30, a fourth servo motor 74 connected to one side of the wire feeding component 20, and a fifth servo motor 75 connected to one side of the ejection component 60.

[0025] The first servo motor 71 drives the impact treadmill assembly 50 to perform periodic reciprocating motion, the second servo motor 72 adopts a torque control mode and a position control mode to perform an electronic cam following motion, and the third servo motor 73, the fourth servo motor 74, and the fifth servo motor 75 adopt a position control mode to perform an electronic cam following motion. The control modes of the servo motor mainly include three types: position control mode, speed control mode, and torque control mode. These three control modes are already existing technologies and will not be described one by one here.

[0026] The platform body 10 is mainly used for installing and connecting various components. The platform body 10 can be configured according to actual assembly requirements, which will not be described in detail here.

[0027] Please also read Figures 2 to 4 The wire feeding assembly 20 includes a plurality of horizontal wire wheels 21 arranged at intervals and crosses, a plurality of vertical wire wheels 22 arranged at intervals and crosses on one side of the horizontal wire wheels 21, a main guide wheel 23 arranged on one side of the vertical wire wheels 22, and a secondary guide wheel 24 arranged on one side of the main guide wheel 23, and a feeding sensor 25 arranged on one side of the shear feeding assembly 30.

[0028] The rotation direction of the horizontal line wheel 21 is in the horizontal plane, and the steel passes through a plurality of the horizontal line wheels 21 to complete its guidance in the horizontal plane. The rotation direction of the vertical line wheel 22 is perpendicular to the rotation direction of the horizontal line wheel 21, so that the steel passes through a plurality of the vertical line wheels 22 to complete its guidance in the vertical direction.

[0029] The main guide wheel 23 and the auxiliary guide wheel 24 are in contact with each other, and there is a circular hole gap between them. The main guide wheel 23 is driven to rotate by the fourth servo motor 74, thereby driving the auxiliary guide wheel 24 to rotate, and the steel passes through the main guide wheel 23 and the auxiliary guide wheel 24, and moves by the rotation of the two guide wheels. The moving direction of the steel is toward the shear feeding assembly 30, and the moving distance of the steel is determined by the rotation angle of the main guide wheel 23. In this way, the rotation angle of the main guide wheel 23 is controlled by the fourth servo motor 74, so as to accurately control the feeding distance of the steel, thereby facilitating the staff to change the line and adjust the machine.

[0030] See also Figure 6 It should be noted that a stopper assembly 80 is provided on one side of the shear feed assembly 30, and the stopper assembly 80 has a stopper arm 81, which corresponds to the output direction of the wire feed assembly 20, that is, the wire feed assembly 20 delivers steel and makes the end of the steel abut against the stopper arm 81 of the stopper assembly 80. When the stopper position needs to be adjusted, the stopper distance of the stopper arm 81 can be changed by twisting the fixing screw 82.

[0031] The feeding sensor 25 is a laser position sensor, which is electrically connected to the fourth servo motor 74, and the output end of the feeding sensor 25 is facing the material blocking assembly 80, so as to obtain the current position of the material blocking assembly 80 and feed back the material blocking distance to the following PLC control program, thereby ensuring the feeding distance of the wire feeding assembly 20.

[0032] The shearing and feeding assembly 30 includes a carriage seat 31 fixedly disposed on one side of the platform body 10, a carriage 32 inserted into the carriage seat 31, a scissor shaft 33 slidably disposed on the carriage seat 31, and a tool clamp rod 34 disposed on one side of the scissor shaft 33.

[0033] The output end of the third servo motor 73 is provided with a gear, and the side of the carriage 32 facing the third servo motor 73 is provided with a rack connected with the gear, so that the third servo motor 73 can make the carriage 32 reciprocate in the carriage seat 31 under the cooperation of the gear and the rack or under the drive of the reciprocating motion device. The reciprocating motion device includes but is not limited to a screw mechanism or a connecting rod cam mechanism. The technology of the cooperation between the scissor shaft 33 and the knife clamp rod 34 to shear and clamp the steel wire is an existing technology, and its specific shearing and clamping conditions can refer to a knife clamp rod anti-shake device disclosed in Chinese patent CN201520791288.9.

[0034] The upper and lower platform assembly 40 includes a dual-rod shaft 41 disposed at the output end of the second servo motor 72 , a slider 42 rotatably connected to the dual-rod shaft 41 , and an upper and lower treadmill 43 fixedly connected to the slider 42 .

[0035] The two ends of the amphibious connecting rod shaft 41 are rotatably arranged on the platform body 10, so that under the drive of the second servo motor 72, the amphibious connecting rod shaft 41 can intermittently swing around its axis and provide high-precision position control movement for the upper and lower platform assembly 40. The middle end of the amphibious connecting rod shaft 41 has two swing arms, and one end of the two swing arms away from the amphibious connecting rod shaft 41 is rotatably connected to the slider 42. The upper and lower running platforms 43 are slidably arranged on the impact running platform assembly 50, and the sliding direction thereof is perpendicular to the sliding direction of the slider 42. The upper and lower running platforms 43 cooperate with the impact running platform assembly 50 to complete the first and second punches of the workpiece, and the specific cooperation will be described below.

[0036] The impact treadmill assembly 50 includes a crankshaft 51 disposed at the output end of the first servo motor 71 , an impact connecting rod 52 rotatably disposed on the crankshaft 51 , and an impact treadmill 53 rotatably disposed at an end of the impact connecting rod 52 away from the crankshaft 51 .

[0037] The first servo motor 71 can drive the crankshaft 51 to rotate, thereby driving the connection point between the impact connecting rod 52 and the crankshaft 51 to rotate. The impact treadmill 53 is slidably arranged on the platform body 10, and its sliding direction is toward the upper and lower platform assembly 40 and perpendicular to the length direction of the crankshaft 51, so that the end of the impact connecting rod 52 away from the crankshaft 51 can drive the impact treadmill 53 to reciprocate on the platform body 10. The upper and lower treadmills 43 are slidably arranged on the side of the impact treadmill 53 away from the impact connecting rod 52, and a first die seat 45 and a second die seat 46 are arranged at intervals on the side of the upper and lower treadmills 43 away from the impact treadmill 53. The arrangement direction of the first die seat 45 and the second die seat 46 is parallel to the sliding direction of the upper and lower running platforms 43, so that when the impact running platform 53 drives the upper and lower running platforms 43 to approach the workpiece, the first die seat 45 corresponds to the workpiece and performs a punch with it, and then the first servo motor 71 drives the impact running platform 53 to reset, and the upper and lower running platforms 43 move away from the workpiece and slide under the drive of the second servo motor 72 so that the second die seat 46 corresponds to the workpiece, so that after the impact running platform 53 drives the upper and lower running platforms 43 to approach the workpiece, the second die seat 46 performs a second punch with the workpiece, thereby completing the first punch and the second punch.

[0038] The ejection assembly 60 includes an ejection rod 61 disposed on one side of the fifth servo motor 75 , and an ejection sensor 62 disposed on one side of the ejection rod 61 .

[0039] The output end of the fifth servo motor 75 is provided with a gear, and the side of the ejector rod 61 facing the fifth servo motor 75 is provided with a rack connected with the gear. The length direction of the ejector rod 61 faces the die position, and under the drive of the fifth servo motor 75, the ejector rod 61 can reciprocate toward the die position through the cooperation of the gear and the rack or under the drive of the reciprocating motion device, so as to eject the workpiece after the die is completed, and complete the ejection and discharging operation. The reciprocating motion device includes but is not limited to a screw mechanism or a connecting rod cam mechanism.

[0040] The ejection sensor 62 is a laser position sensor, which is electrically connected to the fifth servo motor 75. The output end of the ejection sensor 62 is directed toward the end of the ejection rod 61 away from the ejection die position, so that the position of the ejection rod 61 is fed back to the following PLC control program in real time to ensure the ejection distance of the ejection rod 61 during the ejection operation.

[0041] like Figure 5As shown, it is a coordinate diagram of the "Intelligent CNC Heading Machine Electronic Cam Control Coordinate Parameter Curve" provided by the present invention. The intelligent CNC heading machine establishes a motion coordinate system of the electronic cam motion control curve through the rotation angle (X-axis) of the output end of the first servo motor 71 and the movement distance (Y-axis) of the impact treadmill 53, providing the intelligent CNC heading machine with a motion coordinate axis of the electronic cam motion control curve. The second servo motor 72, the third servo motor 73, the fourth servo motor 74, and the fifth servo motor 75 start to perform electronic cam following motion according to the coordinate axis set by the electronic cam motion control curve of the first servo motor 71, thereby establishing the (Y-axis) coordinate system of the electronic cam following motion of the second servo motor 72, the third servo motor 73, the fourth servo motor 74, and the fifth servo motor 75, and drawing the "Intelligent CNC Heading Machine Electronic Cam Control Coordinate Parameter Curve" according to the positional relationship between the control motion of the second servo motor 72, the third servo motor 73, the fourth servo motor 74, and the fifth servo motor 75 and the control motion of the first servo motor 71. According to the coordinate parameter curve, the heading machine can be quickly and accurately adjusted and changed.

[0042] The electrical control system of the intelligent CNC heading machine is composed of PLC, PLC control program and computer control screen, etc. The PLC control program is organized and compiled according to the "Intelligent CNC Heading Machine Electronic Cam Control Coordinate Parameter Curve". The PLC control program includes the setting of variable parameters and fixed quantity parameters in the control program, and the mathematical calculation methods and formulas in the control program. As long as the technical personnel in this field know the working principle of the present invention, they can understand the meaning and principle of the specific calculation methods and formulas. Therefore, these mathematical calculation methods and formulas themselves should be prior art.

[0043] Compared with the prior art, the intelligent CNC heading machine provided by the present invention drives the operation of each component through the first servo motor 71, the second servo motor 72, the third servo motor 73, the fourth servo motor 74, and the fifth servo motor 75, so that the power between these components is independent of each other, thus avoiding the complex connecting rod mechanism, cam mechanism, etc. driven by one power source, and greatly reducing the vibration and noise caused by the mechanical cam movement. The intelligent CNC heading machine sets the control parameters of standard integers such as 50mm, 45mm, 40mm, 35mm, 30mm... in the formula table when it leaves the factory. The debugger can easily change the length of the product from 50mm to 35mm according to the required production. The debugger only needs to call out the formula and use a wrench to adjust the material blocking assembly and the ejection assembly to the values ​​specified by the two laser position sensors to complete the machine adjustment work, which is fast and safe. If the production of non-integer M6 length 36mm, the intelligent CNC heading machine provided by the present invention allows the debugger to adjust the parameters on the control screen according to the length of the screw, and use the slow motion of the servo motor to see whether the electronic cam motion curve is appropriate, so as to produce the first M6*36 screw before the production changeover with high-speed motion and safety. The intelligent CNC heading machine transforms the complex machine adjustment work from manual labor, mechanical motion adjustment and empiricism into digital screen operation, realizing the economical production mode of large, medium and small batches of multi-variety products.
