Description

Technical Field

[0001] The invention relates to the technical field of chain buckle forming, in particular to a chain buckle forming device with a wire straightening function. Background Art

[0002] Iron chains are tools made of iron wires woven by machines. According to different uses, iron chains can be divided into two categories: ornamental iron chains and industrial iron chains. Iron chains are widely used in the industrial field, such as basic parts for mechanical transmission and traction. They are also used as chain-shaped objects that block traffic passages, such as in streets, rivers or at the entrances of harbors. In addition, iron chains are also used in occasions such as highway guardrails and bridge steel chains, showing their important role in safety protection. The materials used to make iron chains are usually galvanized to improve their corrosion resistance and thus extend their service life.

[0003] The existing chain buckle forming devices have the following main problems: (1) Direct stamping causes stress concentration inside the chain and reduces its service life; (2) No lubricant is sprayed during the forming process, resulting in severe wear of the chain; (3) No wire inspection is performed, resulting in bent wire being formed, resulting in defective products.

[0006] The frame is provided with a sliding groove transversely, the detection cylinder slides in the sliding groove, a rectangular groove is provided on one side of the detection cylinder, a metal plate is provided on one side of the detection plate A and the detection plate B, and the other side of the detection plate A and the detection plate B passes through the rectangular groove and is rotatably installed with a detection wheel, the metal plate is in sliding contact with the coil, and the coil and the metal plate are both electrically connected to the control system;

[0007] The detection wheel is hollow inside, and is provided with a filling port connected to the inside. The detection wheel is provided with lubricating liquid inside, and a "V"-shaped groove is provided on the circumference of the detection wheel. Rubber friction plates are provided on both sides of the groove, and a sponge is provided in the middle of the groove. The detection wheel inside the sponge is provided with a spraying hole. During the conveying process of the wire, the wire rubs against the rubber friction plate. Under the action of friction, the detection wheel rotates, and the lubricating liquid in the detection wheel is affected by the centrifugal force of the rotation and gradually sprays outward from the spraying hole. The lubricating liquid is sprayed from the spraying hole onto the sponge, and the sponge smears the lubricating liquid on the surface of the wire to reduce the surface wear caused by subsequent stamping and improve the surface smoothness of the iron chain after forming.

[0008] The punching assembly includes an upper punch plate, a jig and two groups of lower punch plates, the upper punch plate is connected to the telescopic rod of the first oil cylinder, the two groups of lower punch plates are respectively connected to the telescopic rods of the second oil cylinder, the jig is connected to the telescopic oil cylinder, the upper punch plate and the lower punch plate are both slidably connected to the frame, the first oil cylinder and the second oil cylinder are both installed on the frame, the outer side of the jig is adapted to the inner surface of the formed iron chain, the lower side of the jig is provided with a limiting groove, and the frame supports and limits the upper punch plate and the lower punch plate;

[0009] The upper punch plate is located above the two groups of lower punch plates. Limiting plates are arranged on the frames on both sides of the upper punch plate. The limiting plate on the left is placed vertically, and the limiting plate on the right is placed horizontally. A displacement sensor is installed on the limiting plate on the left. A positive plate is arranged on the limiting plate on the left. A guide hole is opened on the limiting plate on the right. A negative plate is arranged in the guide hole of the limiting plate on the right. The positive plate and the negative plate are respectively connected to the positive pole and the negative pole of the power supply through wires.

[0010] When the wire enters the position between the two sets of detection wheels, the encoder in the drive motor feeds back data to the control system. The control system connects the metal plates on the detection plates A and B to the circuit. The current enters from the metal plate in the detection plate A, flows through the effective turns of the coil, and flows out from the metal plate in the detection plate B to the control system. The control system detects the current and obtains the diameter of the wire through calculation. The control system compares the measured diameter data with the set data of the wire. The effective turns at this time refer to the number of coil turns between the metal plates on the detection plates A and B.

[0011] When the measured diameter data is greater than the set diameter data, the control system knows that the wire is deformed and needs to be corrected. The control system connects the metal plate on the detection board A and one end of the coil to the circuit. The current enters from the metal plate in the detection board A, flows through the effective turns of the coil, and flows out from one end of the coil to the control system. The control system detects the current and calculates the height of the upper side of the wire. When the control system obtains the height of the upper side of the wire, the control system cuts off the power to the metal plate in the detection board A, and connects the metal plate in the detection board B and one end of the coil to the circuit. The current enters from the metal plate in the detection board B, flows through the effective turns of the coil, and then flows out from one end of the coil to the control system. The control system detects the current and calculates the height of the lower side of the wire.

[0012] When the control system obtains the height of the upper side and the height of the lower side of the wire, the guide wheel transports the wire forward to the position between the two sets of correction plates, the upper correction electric cylinder drives the correction plate downward, and the lower correction electric cylinder drives the lower correction plate upward, and the correction electric cylinders on both sides drive the correction plates to correct the inclined and bent wires, so that the wires are in a vertical state for subsequent forming. The control system adjusts the extended length of the upper correction electric cylinder according to the measured height of the upper wire, and adjusts the extended length of the lower correction electric cylinder according to the measured height of the lower wire, and the correction electric cylinders on both sides cooperate to drive the correction plates to correct the wires.

[0013] A lifting cylinder is installed between the two groups of lower punches, and the lifting cylinder is vertically installed on the frame. A lifting plate is installed on the piston rod of the lifting cylinder. The lifting plate is slidably connected to the frame. The frame restricts the lifting plate so that the lifting plate can only move up and down. A steering motor is installed on the lifting plate, and a steering plate is installed on the output shaft of the steering motor. An electric clamp is installed on the steering plate.

[0014] The driving motor is installed on the frame, and a conveying unit is provided on the frame between the cutting assembly and the detection cylinder, the correction electric cylinder and the limiting plate on the right side. The driving motor has a built-in encoder, and the encoder is used to monitor the conveying length of the wire.

[0015] The detection cylinder is connected to a telescopic rod of a telescopic cylinder, and the telescopic cylinder is installed on a frame. The telescopic cylinder pulls the detection cylinder to slide in a sliding groove, and multiple positions of the wire can be detected. The sliding groove limits and supports the detection cylinder.

[0016] The cutting assembly includes an upper cross plate and a lower cross plate, the upper cross plate is connected to an upper cutting cylinder, the lower cross plate is connected to a lower cutting cylinder, the upper cross plate and the lower cross plate are both slidably connected to a frame, the frame limits and supports the upper cross plate and the lower cross plate, the upper cutting cylinder and the lower cutting cylinder are installed on the frame, the upper cross plate is located above the lower cross plate, vertical plates are respectively provided on opposite sides of the upper cross plate and the lower cross plate, circular cutting edges are provided on the vertical plates, the circular cutting edges on both sides form a circular ring, the diameter of the circular ring is smaller than the diameter of the wire.

[0017] The correcting electric cylinder is installed on the frame. There are two groups of correcting electric cylinders, which are mirror-imaged. Correcting plates are installed on the telescopic rods of the correcting electric cylinders. The opposite sides of the two groups of correcting plates are provided with grooves that match the surface of the wire.

[0018] The detection plate A and the detection plate B are both connected to the detection cylinder through a spring, and the detection plate A and the detection plate B are slidably connected to the detection cylinder. The conveying wheel is rotatably installed on the frame, and the interior of the conveying wheel is an electric roller structure. The conveying wheel conveys the formed iron chain.

[0019] A control panel is installed on the frame, and a control system is built into the control panel.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Spray lubricating oil on the wire to reduce the wear of the chain. During the conveying process, the wire rubs against the rubber friction plate. Under the action of friction, the detection wheel rotates. The lubricating liquid in the detection wheel is affected by the centrifugal force of rotation and gradually sprays outward from the spray hole. The lubricating liquid is sprayed from the spray hole onto the sponge. The sponge smears the lubricating liquid on the surface of the wire to reduce the surface wear caused by subsequent stamping and improve the surface smoothness of the chain after forming.

[0022] 2. Detect the wires, and then correct them with the correction electric cylinder to improve the forming efficiency of the chain. When the control system obtains the height of the upper side of the wire and the height of the lower side, the guide wheel transports the wire forward to the position between the two sets of correction plates. The upper correction electric cylinder drives the correction plate to move downward, and the lower correction electric cylinder drives the lower correction plate to move upward. The correction electric cylinders on both sides drive the correction plates to correct the inclined and bent wires, so that the wires are in a vertical state for subsequent forming.

The correction electric cylinders on both sides cooperate to drive the correction plates to correct the wires, thereby improving the forming efficiency of the chain.

[0023] 3. Heat the forming position of the chain to reduce stress during the forming process and extend the service life of the chain. After the wire is corrected by the correction cylinder, the guide wheel drives the wire to continue to move forward. After passing through the guide hole in the right limiting plate, the wire contacts the positive plate on the left limiting plate. At the same time, the wire contacts the negative plate in the guide hole. The control system connects the positive plate and the negative plate to the positive and negative poles of the power supply respectively, so that the current flows through the wire between the positive plate and the negative plate. After the current flows through the wire, heat is generated to reduce the stress in the subsequent forming process and extend the service life of the chain. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The correction electric cylinder 4 is installed on the frame 11. There are two groups of correction electric cylinders 4, which are mirror-imaged. A correction plate 401 is installed on the telescopic rod of the correction electric cylinder 4. The opposite sides of the two groups of correction plates 401 are provided with grooves that are adapted to the surface of the wire 12.

[0039] The stamping assembly includes an upper punch plate 41, a fixture 42 and two groups of lower punch plates 43. The upper punch plate 41 is connected to the telescopic rod of the first oil cylinder 411, and the two groups of lower punch plates 43 are respectively connected to the telescopic rods of the second oil cylinder 431.

A displacement sensor is installed on the plate 44, a positive plate 441 is provided on the left limiting plate 44, a guide hole is opened on the right limiting plate 44, a negative plate 442 is provided in the guide hole of the right limiting plate 44, the positive plate 441 and the negative plate 442 are respectively connected to the positive electrode and the negative electrode of the power supply through wires; a lifting cylinder 45 is installed between the two groups of lower punch plates 43, the lifting cylinder 45 is vertically installed on the frame 11, a lifting plate 451 is installed on the piston rod of the lifting cylinder 45, the lifting plate 451 is slidably connected to the frame 11, the frame 11 restricts the lifting plate 451 so that the lifting plate 451 can only move up and down, a steering motor 452 is installed on the lifting plate 451, a steering plate 453 is installed on the output shaft of the steering motor 452, and an electric clamp 454 is installed on the steering plate 453.

[0040] Working principle: Press the start button on the control panel 1, the device starts, the drive motor 2 drives the guide wheel 21 to rotate, the guide wheel 21 conveys the wire 12 forward, and the encoder in the drive motor 2 feeds back the displacement data of the wire 12 to the control system. The control system controls the upper cutting cylinder 221 and the lower cutting cylinder 231 to respectively drive the upper horizontal plate 22 and the lower horizontal plate 23 to move. The upper horizontal plate 22 drives the circular cutting edge downward through the vertical plate, and the lower horizontal plate 23 drives the circular cutting edge upward through the vertical plate, so that the wire 12 between the circular cutting edges on both sides is punched, and the diameter of the wire 12 is reduced after punching and is in an incompletely disconnected state, so as to facilitate the subsequent forming of the iron chain.

[0041] After the wire 12 is punched by the circular cutting edges on both sides, the guide wheel 21 continues to convey the wire 12 forward to the position between the two sets of detection wheels 313. The wire 12 presses the upper detection wheel 313 to move upward and compress the spring. The wire 12 presses the lower detection wheel 313 to move downward and compress the spring, so that the distance between the detection wheels 313 on both sides becomes larger.

[0042] When the wire 12 enters the position between the two sets of detection wheels 313, the encoder in the drive motor 2 feeds back data to the control system, and the control system connects the metal plates on the detection board A311 and the detection board B312 to the circuit respectively. The current enters from the metal plate in the detection board A311, flows through the effective turns of the coil 31, and flows out from the metal plate in the detection board B312 to the control system. The control system detects the current and obtains the diameter of the wire 12 through calculation. The control system compares the measured diameter data with the set data of the wire 12. The effective number of turns at this time refers to the number of turns of the coil 31 between the metal plates on the detection board A311 and the detection board B312.

[0043] When the measured diameter data is greater than the set diameter data, the control system learns that the wire 12 is deformed and needs to be corrected. The control system connects the metal plate on the detection board A311 and one end of the coil 31 to the circuit. The current enters from the metal plate in the detection board A311, flows through the effective turns of the coil 31 (the number of turns between the metal plate on the detection board A311 and one end of the coil 31), and flows out from one end of the coil 31 to the control system. The control system detects the current and obtains the height of the upper side of the wire 12 through calculation by the control system. After the control system obtains the height of the upper side of the wire 12, the control system cuts off the power to the metal plate in the detection board A311, and connects the metal plate in the detection board B312 and one end of the coil 31 to the circuit. The current enters from the metal plate in the detection board B312, flows through the effective turns of the coil 31 (the number of turns between the metal plate on the detection board B312 and one end of the coil 31), and then flows out from one end of the coil 31 to the control system. The control system detects the current and obtains the height of the lower side of the wire 12 through calculation.

[0044] When the control system obtains the height of the upper side and the height of the lower side of the wire 12, the guide wheel 21 transports the wire 12 forward to the position between the two groups of correction plates 401, and the upper correction electric cylinder 4 drives the correction plate 401 to move downward, and the lower correction electric cylinder 4 drives the lower correction plate 401 to move upward, and the correction electric cylinders 4 on both sides drive the correction plates 401 to correct the inclined and bent wire 12, so that the wire 12 is in a vertical state for subsequent forming. The control system adjusts the extended length of the upper correction electric cylinder 4 according to the measured height of the upper wire 12, and adjusts the extended length of the lower correction electric cylinder 4 according to the measured height of the lower wire 12, and the correction electric cylinders 4 on both sides cooperate to drive the correction plates 401 to correct the wire 12.

[0045] After the wire 12 is corrected by the correction electric cylinder 4, the guide wheel 21 drives the wire 12 to continue moving forward. After passing through the guide hole in the right limiting plate 44, the wire 12 contacts the positive plate 441 on the left limiting plate 44. At the same time, the wire 12 contacts the negative plate 442 in the guide hole. The control system connects the positive plate 441 and the negative plate 442 to the positive pole and the negative pole of the power supply respectively, so that the current flows through the wire 12 between the positive plate 441 and the negative plate 442. After the current flows through the wire 12, heat is generated to reduce the stress in the subsequent forming process and extend the service life of the iron chain.

[0046] After the wire 12 is heated by the positive plate 441 and the negative plate 442, the control system controls the telescopic cylinder 421 to drive the fixture 42 to move outward, and then the control system drives the upper punch plate 41 to move downward through the first cylinder 411, cutting the wire 12 while pushing it downward to the fixture 42, and the upper punch plate 41 squeezes the two ends of the wire 12, so that the cut wire 12 is bent on the fixture 42 to form a ring, and then the two groups of second cylinders 431 on the lower side drive the lower punch plate 43 to move upward, and the joints at both ends of the bent wire 12 are squeezed again through the lower punch plate 43, so that the wire 12 is formed as a ring of the iron chain as a whole.

[0047] When a single iron chain is formed, the control system controls the lifting cylinder 45 to drive the lifting plate 451 to move upward, the lifting plate 451 drives the steering motor 452 to move upward, the steering motor 452 drives the electric clamp 454 to move upward through the steering plate 453, and the electric clamp 454 clamps the formed single iron chain. After the single iron chain is clamped, the displacement sensor in the electric clamp 454 feeds back data to the control system, and the control system controls the telescopic cylinder 421 to drive the fixture 42 to move back inward. At this time, the fixture 42 is not in contact with the single iron chain. Afterwards, the lifting cylinder 45 drives the steering motor 452, the steering plate 453, the electric clamp 454 and the single iron chain to move downward through the lifting plate 451.

[0048] When the lifting cylinder 45 drives the single chain to move to the lowermost side, the displacement sensor in the lifting cylinder 45 feeds back data to the control system, and the control system continues to transport the new wire 12 forward through the guide wheel 21, so that the new wire 12 contacts the positive plate 441 and cooperates with the negative plate 442 to be heated again. After that, the steering motor 452 drives the electric clamp 454 to rotate 90 degrees through the steering plate 453, and the electric clamp 454 drives the single chain to rotate 90 degrees to facilitate the subsequent series connection of the chains.

[0049] After the single iron chain rotates 90 degrees, the lifting cylinder 45 drives the steering motor 452, the steering plate 453, the electric clamp 454 and the single iron chain to move upward through the lifting plate 451, so that the upper end of the single iron chain contacts the limit groove. After that, the upper punch plate 41 and the lower punch plate 43 are driven by the first cylinder 411 and the second cylinder 431 respectively to punch the new wire 12 into a circular iron chain again, so that the two circular iron chains are fitted together to form a series connection, thereby realizing the buckle forming of the iron chain.

[0050] After being connected in series, the iron chains move downward and contact the conveying wheel 5, and the conveying wheel 5 conveys the iron chains downward for further processing.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
