Description

Technical Field

[0001] The invention relates to a metal wire processing technology, and in particular to a wire cutting device for processing a spring pin connector. Background Art

[0002] Metal wire is a common industrial material used in the manufacturing industry. The slender metal wire is usually wound on a reel for transportation and storage. When using the metal wire, it needs to be cut into the required length. Due to the long-term winding, there is a certain stress inside the metal wire, which keeps it in a bent state. At this time, a straightening and cutting machine is needed to straighten and cut the metal wire.

[0003] A Chinese invention patent with announcement number CN115780684B discloses a metal wire straightening and cutting device, which is provided with a swinging double-roller multi-purpose metal wire stress elimination and straightening mechanism, so that the lower roller repeatedly squeezes the metal wire during the swinging process. By increasing the number of swinging double-roller multi-purpose metal wire stress elimination and straightening mechanisms and making the adjacent swinging lower roller mechanisms swing in opposite directions, the residual stress in the metal wire can be effectively eliminated and the metal wire can be straightened. A compression spring is provided between the upper roller slider and the vertical sliding track. The elastic force generated by the compression spring pushes the upper roller to squeeze the metal wire through the upper roller slider. The compression amount of the compression spring is adjusted by the spring adjustment knob to adjust the elastic force generated by the compression spring, so as to adapt to metal wires with lower hardness and prevent the metal wires from being deformed during the extrusion process and affecting subsequent use.

[0004] When the existing equipment is in use, the wire supply method is unstable, which leads to cutting position deviation, thus affecting the quality of the entire wire cutting.

In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] Example: See Figure 1-Figure 10 A wire cutting device for processing a spring pin connector includes a base 1, movable plates 11 are slidably installed on both sides of the base 1, a cover plate 12 is arranged on the upper end of the movable plate 11, a shearing piece 13 is arranged on one end of the movable plate 11, and a fixing component 2 is arranged at the lower end of the cover plate 12 and between the two movable plates 11, and the wire is limited by the fixing component 2.

[0040] In this solution, the movable plate 11 can be freely adjusted to facilitate the maintenance of the components inside the base 1. At the same time, the shearing piece 13 is composed of a cutting blade, a motor and an electric telescopic rod, and is connected to an external control device. The cutting blade is connected to the output end of the motor, and the cutting blade is extended and retracted in cooperation with the electric telescopic rod to cut the wire.

[0041] Furthermore, the fixing assembly 2 includes a fixing block 21 connected to the cover plate 12, a supporting block 22 is disposed at the lower end of the fixing block 21, and a fixing plate 26 is disposed at one end of the supporting block 22 away from the fixing block 21. A driving member 25 is disposed in the inner cavity of the supporting block 22, and an output end of the driving member 25 penetrates and extends to the interior of the fixing plate 26.

[0042] Slide grooves 261 are provided at the middle positions of both sides of the fixing plate 26 , and slide bars 262 are slidably mounted on the inner walls of the slide grooves 261 , and two push rods 263 are rotatably mounted at the middle positions of the outer surfaces of the slide bars 262 .

[0043] In this embodiment, the driving member 25 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. When the driving member 25 is started, it synchronously drives the sliding rod 262 arranged at its output end to move, wherein the movement trajectory of the sliding rod 262 is limited by the sliding groove 261. When the sliding rod 262 moves, it drives the push rod 263 installed on the outer surface of the sliding rod 262 to move.

[0044] Furthermore, the inner cavity of the fixed plate 26 is symmetrically provided with clamping blocks 27, and at the same time, the ends of the two clamping blocks 27 away from each other are provided with adjusting rods 271, and arc grooves 264 are opened on both sides of the end of the fixed plate 26 away from the sliding groove 261, and the inner wall of the arc groove 264 is slidably connected to the outer surface of the adjusting rod 271, and positioning rods 272 are provided on both sides of the clamping blocks 27 and on one side of the adjusting rod 271, and the two ends of the positioning rod 272 are rotatably connected to the inner wall of the fixed plate 26, and the ends of the two push rods 263 away from the sliding rod 262 are rotatably connected to the ends of the two clamping blocks 27 respectively.

[0045] Specifically, when the push rod 263 moves, the clamping block 27 that is rotatably connected to the push rod 263 is synchronously driven to move. Since a positioning rod 272 is provided on one side of the clamping block 27, when the clamping block 27 is moved by force, it rotates around the positioning rod 272, so that the end of the clamping block 27 away from the push rod 263 moves toward the middle or expands toward both ends.

[0046] At the same time, an arc groove 264 is provided on the fixed plate 26 to limit the adjustment rod 271 on the clamp block 27, so that when the clamp block 27 rotates, the adjustment rod 271 moves along the inner wall of the arc groove 264, thereby protecting the rotation process of the clamp block 27 and preventing the clamp block 27 from rotating in the opposite direction during rotation.

[0047] Furthermore, limit blocks 23 are provided on both sides of the support block 22 , and the limit blocks 23 are used to protect both sides of the wire cutting end.

[0048] Specifically, the end of the limit block 23 is arc-shaped, which is used to support the outer surface of the wire. At the same time, a cutting groove is provided at the end of the limit block 23, so that when the wire is cut, both sides of the cut end of the wire can be protected to prevent warping.

[0049] Furthermore, the adjusting component 3 is assembled on the upper end of the base 1 , and the processed wire is tightened by the adjusting component 3 .

[0050] The adjustment assembly 3 includes a base 31 connected to the base 1, the cross section of the base 31 is U-shaped, and a support rod 32 is rotatably mounted on the inner wall of the base 31, and a movable block 33 is symmetrically arranged on the outer surface of the support rod 32. The outer surface of the movable block 33 is provided with multiple groups of connecting blocks 34, and the multiple groups of connecting blocks 34 are evenly distributed on the outer surface of the movable block 33.

[0051] A limiting rod 35 is rotatably mounted on the end of each connection block 34 , and the outer surfaces of the two limiting rods 35 are in contact with each other. A positioning pin 36 is provided at the contacting position of the two limiting rods 35 .

[0052] In this embodiment, the limit rod 35 can be driven to move synchronously by moving the two movable blocks 33. Since the outer surface of the limit rod 35 is connected by the positioning pin 36, when the movable block 33 moves, the connection of the limit rod 35 can be driven to expand to both sides or shrink to the middle, thereby tightening the wire wound on the limit rod 35, ensuring that the wire is always in a taut state during transportation and shearing, thereby reducing damage caused by shearing.

[0053] Furthermore, first elastic members 37 are symmetrically arranged on the outer surface of the support rod 32 , and opposite ends of the two first elastic members 37 are respectively connected to the two movable blocks 33 , and ends away from each other are in contact with the inner wall of the base 31 .

[0054] Specifically, the first elastic member 37 is an elastic component such as a spring, and the movable block 33 is limited by the first elastic member 37, thereby pushing the movable block 33, so that the first elastic member 37 is in a taut state, thereby maintaining a stable tension level for the wire wound on the limiting rod 35 when entering the cutting area, thereby ensuring the cutting accuracy and product size consistency.

[0055] Furthermore, a limiting component 4 is installed between the fixing component 2 and the adjusting component 3 to protect the wire transportation.

[0056] The limiting assembly 4 includes a support plate 41 connected to the base 1, and a positioning plate 42 is arranged on the outer surface of the support plate 41. A slot 43 is opened at one end of the support plate 41 close to the positioning plate 42, and rollers 44 are symmetrically arranged on the inner wall of the slot 43, and two rollers 44 are respectively located on both sides of the positioning plate 42.

[0057] In this embodiment, the end of the wire passes through the roller 44, the limiting wheel 46 and the roller 44 in sequence, and extends to the limiting end of the fixing component 2, thereby fixing the wire to facilitate cutting. The limiting wheel 46 and the roller 44 cooperate to protect the wire during transportation.

[0058] Furthermore, guide grooves 45 are provided on both sides of the inner wall of the slot hole 43, and a limit wheel 46 is slidably mounted on the inner wall of the guide groove 45. Protective blocks 48 are provided at both ends of the limit wheel 46, and a second elastic member 47 is provided at one end of the protective block 48, and the end of the second elastic member 47 away from the protective block 48 is connected to the positioning plate 42.

[0059] Specifically, after the wire passes through the roller 44, the limiting wheel 46 and the roller 44 in sequence, the limiting wheel 46 is supported by the second elastic member 47, so that the wire is always in a taut state, helping the wire to maintain linear motion and preventing it from deviating from the track during the cutting process, wherein the second elastic member 47 is an elastic component such as a spring.

[0060] The control device can select any controller to be connected to the electrical components in this application, so as to control the opening and closing operation of each electrical component. This part is the prior art. Here, a single-chip microcomputer can be provided as a control unit for demonstration. The single-chip microcomputer in this embodiment is a typical embedded microcontroller, which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but it has a small storage capacity, a simple input and output interface, and low functional consumption.

[0061] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
