Technical Field

[0001] The present invention relates to the field of machine tools, devices or process technologies for grinding or polishing, and in particular to an intelligent manufacturing device for constant force springs. Background Art

[0002] Constant force spring is a special tension spring, which is suitable for occasions with large stretching amount and no load increase. Constant force spring needs to change the strength and toughness of spring material by heating the material, and bend the metal wire into the required shape. Intelligent manufacturing device can bend the metal wire into spring shape. Intelligent manufacturing device is usually composed of multiple molds and punches. Through different combinations and adjustments, the metal wire is processed. The precision and stability of the forming mechanism are completed by the control system of the intelligent manufacturing device, thereby completing the processing process of constant force spring. Technical enlightenment for intelligent manufacturing device; Research on intelligent manufacturing devices has found the following problems: After the intelligent manufacturing device forms the constant force spring through the forming mechanism, the constant force spring is discharged through the discharging mechanism. After the constant force spring is discharged, the elasticity of the constant force spring needs to be tested, so that the intelligent manufacturing device cannot test the elasticity of the constant force spring during the discharging process, and thus cannot reduce the subsequent testing steps of the constant force spring. At present, CN202010017192.2 in the prior art discloses a processing device for a valve seat check spring, wherein the left side of the inner cavity of the spring machine body is fixedly connected to a servo motor, and the inner cavity of the spring machine body is located on the top of the servo motor and is movably connected to a wire pay-off reel, and the middle part of the lower surface of the wire pay-off reel is fixedly engaged with the top of the servo motor output shaft, and the middle part of the inner cavity of the spring machine body is provided with a rust-proof device, and the middle part of the upper surface of the spring machine body is fixedly connected to a cleaning device. The processing device for the valve seat check spring, through the positive cross section of the opening of the guide wheel presents two openings of oppositely symmetrical semicircular arcs, utilizes the rust removal block on the driving motor to drive the elastic steel wire to slide, and at the same time utilizes the rebound force provided by the elastic component at the bottom of the guide wheel and the elastic steel wire to offset the elastic force of the guide wheel, thereby reducing the rebound elasticity of the elastic steel wire during the processing process and improving the accuracy of the forming size of the check spring; The present invention can mainly solve the problem that the intelligent manufacturing device is unable to detect the elastic formation of the constant force spring during the discharging process.

[0004] The purpose and efficacy of the constant force spring intelligent manufacturing device of the present invention are achieved by the following specific technical means: a constant force spring intelligent manufacturing device, including a frame, a motor is provided at the lower end of the frame, a feeding mechanism and a forming mechanism are respectively distributed at the upper end of the frame, a machine box is provided on the side of the frame close to the forming mechanism, and a discharging rack is slidably nested on one side of the upper end of the machine box.

[0005] Furthermore, the motor is connected to a power supply circuit via a power supply line, and a controller is provided on one side of the frame, and the controller is connected to the motor circuit.

[0006] Furthermore, the feeding mechanism is composed of a feeding wheel, a clamping wheel and a guide wheel, and the motor is rotationally connected to the feeding mechanism through a belt.

[0007] Furthermore, the feeding mechanism transfers the metal wire to one side of the forming mechanism.

[0008] Furthermore, the forming mechanism is usually composed of a plurality of dies and punches, and the punches punch the metal wires so that the metal wires are processed into constant force springs.

[0009] Furthermore, one end of the punch is connected to a press, and the press is connected to a controller circuit.

[0010] Furthermore, the machine box is concave, the discharging rack is located on a side of the machine box close to the forming mechanism, the discharging rack is arranged in an arc shape, and the discharging rack as a whole is tilted downward by 5-15 degrees.

[0011] Furthermore, a cross bar is rotatably passed through the upper end of the discharging rack, and a lining plate is swingably connected to one side of the lower end of the cross bar, and the lining plate is located inside the machine box.

[0012] Furthermore, the lower end of one side of the cross bar extends to the interior of the machine box, and the cross bar rotates horizontally with this side as a support point. The cross bar passes through the upper end of the discharge rack in a transverse manner, and the cross bar and the lining plate are arranged at 90 degrees as a whole.

[0013] Furthermore, a track is provided on the inner wall of the machine box near the lining plate, a sliding rod is slidably connected inside the track, an inclined rod is slidably connected to one end of the sliding rod near the lining plate, a magnet is provided on one side of the sliding rod, and a spring is elastically connected to one side of the track near the magnet.

[0014] Furthermore, the inclined rod is inclined at 25-90 degrees in the horizontal direction, the lining plate is slidably connected to the sliding rod through the inclined rod, and the sliding rod slides in the horizontal direction inside the track.

[0015] Furthermore, grooves are provided inside the track, the grooves are arranged horizontally, and the sliding rods slide inside the grooves.

[0016] Furthermore, the sliding rod and the oblique rod are arranged in a "T" shape on the side.

[0017] Furthermore, the magnet is magnetically attracted to one end of the spring, and the spring is installed laterally inside the track.

[0018] Furthermore, a turntable is rotatably connected to one side of the upper end of the discharging rack, a push rod is rotatably connected to one side of the turntable close to the cross bar, and bumps are distributed on the outer side of the turntable.

[0019] Furthermore, one end of the push rod close to the turntable is located on one side of the upper end of the turntable, the push rod is horizontally inclined at 15-35 degrees, and the turntable rotates horizontally on one side of the upper end of the discharge rack.

[0020] Furthermore, the turntable extends to one side of the upper end of the discharging rack, and the protrusion is located on one side of the turntable close to the middle of the discharging rack.

[0021] Beneficial effects: 1. One side of the lower end of the crossbar rotates and penetrates the upper end of the discharging rack, while the other side of the crossbar horizontally penetrates the upper end of the discharging rack. When the constant force spring slides on the upper end of the discharging rack, the constant force spring is squeezed to one side of the crossbar, and the crossbar rotates horizontally on one side of the discharging rack. At this time, the crossbar rotates toward one side of the discharging rack, and the crossbar drives the lining plate to rotate synchronously; 2. When the cross bar rotates due to the constant force spring, the lining plate rotates synchronously, and the lining plate can drive the diagonal rod to slide toward one side of the track. The diagonal rod is inclined 25-90° in the horizontal direction. Therefore, when the lining plate rotates in the horizontal direction, the lining plate can drive the sliding rod to slide through the diagonal rod, and the sliding rod can slide horizontally inside the track. At this time, the sliding rod slides toward one side of the spring, and the spring rebounds one end of the sliding rod; 3. When the extrusion force of the constant force spring on the cross bar is greater than the resilience of the spring, the cross bar swings to one side of the discharge rack. At this time, the constant force spring can enter the interior of the machine box through the discharge rack. By replacing springs with different elastic forces, the elasticity of the constant force spring can be tested when the constant force spring slides on one side of the discharge rack. 4. After the constant force spring passes through one side of the cross bar, the sliding rod can slide back on the inner side of the track by utilizing the resilience of the spring. The sliding rod can drive the lining plate to return and rotate through the inclined rod, and then the lining plate can drive the cross bar to return, which is convenient for the detection of the next constant force spring; 5. When the cross bar rotates at the upper end of the discharging rack, the cross bar drives the turntable to rotate horizontally reciprocatingly through the push rod. During the rotation of the turntable, the protrusion can be driven to rotate synchronously. Through the rotation of the protrusion above the discharging rack, the discharging of the constant force spring can be separated, avoiding the accumulation of the constant force spring at the upper end of the discharging rack. This makes it possible for the intelligent manufacturing device to detect the elasticity of the constant force spring during the discharging process and facilitate the separation of the constant force spring.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Example: As attached Figure 1 To Attachment Figure 8 As shown: Embodiment 1: A constant force spring intelligent manufacturing device comprises a frame 1, a motor 101 is provided at the lower end of the frame 1, a feeding mechanism 102 and a forming mechanism 103 are respectively distributed at the upper end of the frame 1, a machine box 2 is provided on one side of the frame 1 close to the forming mechanism 103, and a discharging frame 201 is slidably nested on one side of the upper end of the machine box 2; Wherein: the motor 101 is connected to the power supply circuit through a power line, a controller is provided on one side of the frame 1, and the controller is connected to the circuit of the motor 101; The feeding mechanism 102 is composed of a feeding wheel, a clamping wheel and a guide wheel, and the motor 101 is rotatably connected to the feeding mechanism 102 through a belt; The feeding mechanism 102 transfers the metal wire to one side of the forming mechanism 103; The forming mechanism 103 is usually composed of a plurality of dies and punches, and the punches press the metal wires to form constant force springs; One end of the punch is connected to a press, and the press is connected to a controller circuit; The machine box 2 is concave, and the discharge rack 201 is located on the side of the machine box 2 close to the forming mechanism 103. The discharge rack 201 is arranged in an arc shape, and the discharge rack 201 is tilted downward by 5-15 degrees as a whole; Wherein: the motor 101 drives the feeding mechanism 102 to rotate, and the feeding wheel of the feeding mechanism 102 drives the metal wire to be transported to one side of the forming mechanism 103. The forming mechanism 103 is usually composed of a plurality of dies and punches. The punches punch the metal wires to make the metal wires into constant force springs. Then the constant force springs fall to the upper end of the discharge rack 201. Since the discharge rack 201 is tilted downward by 5-15° as a whole, the constant force springs can slide toward the inside of the machine box 2 through the discharge rack 201 and then be stored in the inside of the machine box 2. Example 2: Refer to the attached manual Figure 2-6 It can be seen that the difference between Example 2 and Example 1 is that the upper end of the discharge frame 201 is rotatably penetrated by a cross bar 202, and one side of the lower end of the cross bar 202 is swingably connected to a lining plate 203, and the lining plate 203 is inside the machine box 2; Among them: the lower end of one side of the cross bar 202 extends to the inside of the machine box 2, and the cross bar 202 rotates horizontally with this side as the support point, and the cross bar 202 runs through the upper end of the discharge rack 201 in a horizontal direction, and the cross bar 202 and the lining plate 203 are arranged at 90 degrees as a whole; The lower end of one side of the cross bar 202 extends to the inside of the machine box 2, and the cross bar 202 rotates horizontally with this side as the support point. Figure 7 As shown; The cross bar 202 is horizontally passed through the upper end of the discharging frame 201. When the spring slides on the upper end of the discharging frame 201, the spring is pressed to one side of the cross bar 202, and the cross bar 202 rotates horizontally on one side of the discharging frame 201. When the crossbar 202 rotates, the lining plate 203 rotates synchronously; Among them: one side of the lower end of the cross bar 202 rotates and penetrates the upper end of the discharge rack 201, and the other side of the cross bar 202 horizontally penetrates the upper end of the discharge rack 201. When the constant force spring slides on the upper end of the discharge rack 201, the constant force spring is squeezed to one side of the cross bar 202, and the cross bar 202 rotates horizontally on one side of the discharge rack 201. At this time, the cross bar 202 rotates toward one side of the discharge rack 201, and the cross bar 202 drives the lining plate 203 to rotate synchronously; Example 3: Refer to the attached manual Figure 3-8 It can be seen that the difference between Example 3 and Examples 1 and 2 is that a track 4 is provided on the inner wall of the machine box 2 near the lining plate 203, a sliding rod 301 is slidably connected inside the track 4, an end of the sliding rod 301 near the lining plate 203 is slidably connected to the inclined rod 3, a magnet 302 is provided on one side of the sliding rod 301, and a spring 401 is elastically connected to one side of the track 4 near the magnet 302; Wherein: the inclined rod 3 is inclined 25-90 degrees in the horizontal direction, the lining plate 203 is slidably connected with the sliding rod 301 through the inclined rod 3, and the sliding rod 301 slides horizontally inside the track 4; The inclined rod 3 is inclined 25-90 degrees in the horizontal direction, so when the lining plate 203 rotates in the horizontal direction, the lining plate 203 can drive the sliding rod 301 to slide through the inclined rod 3, and the sliding rod 301 can slide in the horizontal direction inside the track 4; The track 4 has grooves arranged in a transverse direction, and the sliding rod 301 slides in the grooves; The sliding rod 301 and the oblique rod 3 are arranged in a "T" shape on the side; The magnet 302 is magnetically attracted to one end of the spring 401, and the spring 401 is installed in a horizontal direction inside the track 4; Wherein: when the cross bar 202 rotates due to the squeezing of the constant force spring, the lining plate 203 rotates synchronously, and the lining plate 203 can drive the inclined rod 3 to slide toward one side of the track 4. The inclined rod 3 is inclined 25-90 degrees in the horizontal direction. Therefore, when the lining plate 203 rotates in the horizontal direction, the lining plate 203 can drive the sliding rod 301 to slide through the inclined rod 3, and the sliding rod 301 can slide in the horizontal direction inside the track 4. At this time, the sliding rod 301 slides toward one side of the spring 401, and the spring 401 rebounds one end of the sliding rod 301; When the squeezing force of the constant force spring on the cross bar 202 is greater than the resilience of the spring 401, the cross bar 202 swings to one side of the discharge rack 201. At this time, the constant force spring can enter the interior of the machine box 2 through the discharge rack 201. By replacing the spring 401 with different elastic forces, the elasticity of the constant force spring can be detected when the constant force spring slides on one side of the discharge rack 201. After the constant force spring passes through one side of the cross bar 202, the sliding rod 301 can slide back on the inner side of the track 4 by utilizing the resilience of the spring 401, and the sliding rod 301 can drive the lining plate 203 to return and rotate through the inclined rod 3, and then the lining plate 203 can drive the cross bar 202 to return, so as to facilitate the detection of the next constant force spring; Example 4: Refer to the attached manual Figure 3-6 It can be seen that the difference between Example 4 and Examples 1-3 is that a turntable 501 is rotatably connected to one side of the upper end of the discharge rack 201, a push rod 5 is rotatably connected to the side of the turntable 501 close to the cross bar 202, and bumps 502 are distributed on the outer side of the turntable 501; Among them: the end of the push rod 5 close to the turntable 501 is located on one side of the upper end of the turntable 501, the push rod 5 is horizontally inclined at 15-35 degrees, and the turntable 501 rotates horizontally on one side of the upper end of the discharge rack 201; The turntable 501 extends to one side of the upper end of the discharge rack 201, and the protrusion 502 is located on one side of the turntable 501 close to the middle of the discharge rack 201. Figure 3 As shown; Among them: when the cross bar 202 rotates at the upper end of the discharge rack 201, the cross bar 202 drives the turntable 501 to rotate horizontally reciprocatingly through the push rod 5. During the rotation of the turntable 501, the protrusion 502 can be driven to rotate synchronously. Through the rotation of the protrusion 502 above the discharge rack 201, the discharge of the constant force spring can be separated, avoiding the accumulation of the constant force spring at the upper end of the discharge rack 201, so that this kind of intelligent manufacturing device can detect the elasticity of the constant force spring during the discharge process, and at the same time, it is convenient to separate the constant force spring.
