Description

Technical Field

[0001] This application relates to the field of heating wire manufacturing equipment, and in particular to an automatic twisting, bending and shearing device. Background Technology

[0002] Heating wire is a type of electrothermal alloy that generates heat by utilizing the electrical resistance of metals. It is widely used and in high demand in industrial production. To improve the heating capacity of the heating wire, it is usually necessary to twist it during production to increase its total length and thus the amount of heat generated when energized.

[0003] The heating wire manufacturing process includes twisting and cutting. The raw material for the heating wire is a cylindrical coil. Users need to straighten the end of the heating wire, then fold and twist the drawn heating wire. The two ends of the twisted heating wire are then cut off to obtain the heating wire product.

[0004] The aforementioned technical solutions have the following drawbacks: the production process of the heating wire is cumbersome, and manual production is inefficient, resulting in low production efficiency. Utility Model Content

[0005] To improve the automation level of heating wire manufacturing, this application provides an automatic twisting, bending and shearing device.

[0006] The automatic wire twisting, bending, and shearing device provided in this application adopts the following technical solution:

[0007] An automatic wire twisting, bending and shearing device includes a worktable, multiple feeding mechanisms, multiple twisting mechanisms and multiple shearing mechanisms. The worktable is horizontally arranged, and the feeding mechanism, twisting mechanism and shearing mechanism are arranged in groups. The feeding mechanism is used to place the heating wire coil, the twisting mechanism is used to hook the heating wire and twist the heating wire, and the shearing mechanism is used to cut the heating wire.

[0008] By adopting the above technical solution, multiple feeding mechanisms are set on the workbench, and each feeding mechanism can be equipped with a heating wire coil. The heating wire coil is set on the torsion mechanism, which twists the heating wire. The shearing mechanism cuts off the twisted heating wire. The user then sets the heating wire coil on the torsion mechanism, achieving the effect of high-efficiency production of heating wire. The user can simultaneously control the actions of two feeding mechanisms, the torsion mechanism, and the shearing mechanism, thereby improving production efficiency.

[0009] Optionally, the torsion mechanism includes a torsion motor and a hook. The housing of the torsion motor is fixed on the worktable, and the output shaft of the torsion motor is connected to the hook, which is used to hook the heating wire.

[0010] By adopting the above technical solution, by setting a hook on the torsion motor, the output shaft of the torsion motor is set horizontally, so that the torsion motor can drive the hook to rotate. When the heating wire is folded in half and hung on the hook, the torsion motor can efficiently torsion the heating wire.

[0011] Optionally, the feeding mechanism includes a base, a fixing rod, a clamping assembly, and a shearing blade. The base is mounted on the workbench, the fixing rod is horizontally set and one end is fixed to the base. When the heating wire is hooked onto the hook, the clamping assembly is used to clamp the end of the heating wire. The shearing blade is slidably set on the base and is used to cut the untwisted heating wire in the clamping assembly after twisting. The shearing mechanism is used to cut the connection end between the twisted heating wire and the hook.

[0012] By adopting the above technical solution, a fixing rod is set on the base so that the heating wire coil can be sleeved on the fixing rod. After the end of the heating wire coil is straightened, it is hung on the hook. The end of the heating wire is fixed by the clamping assembly. At this time, the twisting motor drives the hook to rotate, so as to achieve the effect of twisting the heating wire. After the heating wire is twisted, the shearing blade and the shearing mechanism are activated to cut the two ends of the twisted heating wire, so that the twisted heating wire has a regular shape.

[0013] Optionally, a rotary motor is installed on the worktable, the housing of the rotary motor is fixed on the worktable, the output shaft of the rotary motor is perpendicular to the worktable, the base is connected to the output shaft of the rotary motor, and the rotary motor is used to drive the base to rotate.

[0014] By adopting the above technical solution, a rotary motor is set on the base, which can drive the base to rotate. The rotary motor is used to bend the twisted heating wire to 90°. When the twisting mechanism twists the heating wire, the rotary motor drives the base to rotate. At this time, the connection between the twisted heating wire and the heating wire coil bends and yields, making it easier for the shearing knife to cut the heating wire.

[0015] Optionally, a sensor start switch is provided on the base, which is used to detect whether the heating wire has been placed in the clamping assembly.

[0016] By adopting the above technical solution and setting an inductive start switch on the base, when the heating wire is hung on the hook and its end is clamped by the clamping assembly, the mover on the clamping assembly moves and its position changes. The inductive start switch can detect the change in the position of the clamping assembly, and the user can control the operation of the feeding mechanism and the torsion mechanism. When the heating wire is not placed in the clamping assembly, the feeding mechanism and the torsion mechanism cannot operate, and the user needs to manually place the heating wire into the clamping assembly. During the process of the user placing the heating wire into the clamping assembly, the torsion mechanism will not operate, reducing the chance of the hook rotating and scratching the user.

[0017] Optionally, the shearing mechanism is equipped with a driving component, which drives the shearing mechanism to reciprocate along a linear direction.

[0018] By adopting the above technical solution, by setting a driving component on the shearing mechanism, the driving component can drive the shearing mechanism to move back and forth in a horizontal straight line. When the torsion mechanism twists the heating wire, the shearing mechanism can cut the heating wire. When it is necessary to hang the heating wire on the hook, the shearing mechanism can move away from the torsion mechanism through the driving component, thereby making it convenient for users to connect the heating wire to the torsion mechanism and reducing the chance of the shearing mechanism scratching the users.

[0019] Optionally, a slide rail is slidably connected to the drive component, the slide rail is fixed on the worktable, the length direction of the slide rail is perpendicular to the length direction of the drive component, and a fixing bolt is threadedly connected to the drive component, the fixing bolt is used to abut against the slide rail.

[0020] By adopting the above technical solution, by setting a slide rail on the drive component, the drive component and the shearing mechanism can slide along the length direction of the slide rail. The user can adjust the position of the shearing mechanism, so that the shearing mechanism and the cutting blade can cut the twisted heating wire to a predetermined length, which makes it convenient to control the length of the heating wire product.

[0021] Optionally, a placement board is provided above the workbench, and the placement board is set horizontally.

[0022] By adopting the above technical solution, and by setting up a placement plate above the workbench, users can place the processed heating wire and the tools or measuring instruments required for processing on the placement plate, which is convenient for use.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By setting multiple feeding mechanisms on the workbench, each feeding mechanism can be equipped with a heating wire coil. The heating wire coil is set on the torsion mechanism, which twists the heating wire. The rotation mechanism bends the heating wire at 90°. The shearing mechanism cuts off the twisted and bent heating wire. The user then sets the heating wire coil on the torsion mechanism, achieving high-efficiency production of heating wire. The user can simultaneously control the actions of two feeding mechanisms, the torsion mechanism, the rotation mechanism, and the shearing mechanism, thus improving production efficiency.

[0025] 2. By setting a hook on the torsion motor, the output shaft of the torsion motor is set horizontally, so that the torsion motor can drive the hook to rotate. When the heating wire is folded in half and hung on the hook, the torsion motor can efficiently twist the heating wire.

[0026] 3. By setting a fixing rod on the base, the heating wire coil can be sleeved on the fixing rod. After the end of the heating wire coil is straightened, it is hung on the hook. The end of the heating wire is fixed by the clamping assembly. At this time, the twisting motor drives the hook to rotate, so as to achieve the effect of twisting the heating wire. After the heating wire is twisted, the shearing knife and the shearing mechanism are activated, thereby cutting the two ends of the twisted heating wire, so that the twisted heating wire is in a regular shape.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses an automatic wire twisting, bending, and cutting device, referring to... Figure 1 and Figure 2 The system includes a worktable 1, multiple feeding mechanisms 2, multiple torsion mechanisms 3, and multiple shearing mechanisms 4. The worktable 1 is horizontally positioned, and the feeding mechanisms 2, torsion mechanisms 3, and shearing mechanisms 4 are mounted on the worktable 1. These mechanisms are grouped together, and the heating wire is automatically processed through them. By setting multiple groups of feeding mechanisms 2, torsion mechanisms 3, and shearing mechanisms 4 on the worktable 1, production efficiency is improved. A single operator can sequentially operate different feeding mechanisms 2, torsion mechanisms 3, and shearing mechanisms 4, thereby increasing processing efficiency.

[0034] Reference Figure 1The workbench 1 has several horizontally arranged placement plates 11 for placing processed heating wires or other tools. The feeding mechanism 2 includes a base 21, a fixing rod 22, a clamping assembly 23, and a shearing blade 24. The base 21 is mounted on the workbench 1, and one end of the fixing rod 22 is fixed to the base 21. The fixing rod 22 is horizontally positioned. The heating wire is made of tubular metal wire, and the heating wire coil can be sleeved on the fixing rod 22. The clamping assembly 23 is a pneumatic finger fixed to the base 21 and is used to clamp the heating wire. The shearing blade 24 is positioned between the fixing rod 22 and the clamping assembly 23. The shearing blade 24 is driven by a power device such as a cylinder and can reciprocate horizontally. The shearing blade 24 is used to cut the untwisted heating wire in the clamping assembly 23 after twisting. After the user places the heating wire coil onto the fixing rod 22, they pull out the heating wire coil and clamp it onto the torsion mechanism 3. The clamping assembly 23 holds the middle and end of the heating wire, causing the torsion mechanism 3 to twist the heating wire. Then, the shearing blade 24 actuates and cuts the twisted heating wire from the heating wire coil. After the user removes the cut twisted heating wire, they can pull out the end of the heating wire coil, hang it on the torsion mechanism 3, and fix the end of the heating wire to the clamping assembly 23 to continue production.

[0035] Reference Figure 2 The torsion mechanism 3 includes a torsion motor 31 and a hook 32. The housing of the torsion motor 31 is fixed on the worktable 1. The output shaft of the torsion motor 31 is connected to the hook 32, which is used to hook the heating wire. When the torsion motor 31 drives the hook 32 to rotate, it can torsion the heating wire. The user straightens the end of the heating wire coil and folds the heating wire in half so that the hook 32 hooks the heating wire. At this time, the clamping assembly 23 clamps the two ends of the heating wire, so that the torsion mechanism 3 can twist the folded heating wire.

[0036] Reference Figure 1 A rotary motor 211 is mounted on a base 21. The housing of the rotary motor 211 is fixed to the worktable 1. The output shaft of the rotary motor 211 is vertically positioned and connected to the base 21. The rotary motor 211 drives the base 21 to rotate. The rotary motor 211 is used to bend the twisted heating wire to 90°. When the heating wire is twisted, the base 21 rotates back and forth via the rotary motor 211, thereby bending the connection between the twisted heating wire and the heating wire coil, making the cuts made by the shearing blade 24 neat and improving the processing quality. In other embodiments, the rotary motor 211 can be connected to the base of the torsion motor 31. The base is rotatably connected to the worktable 1, and the housing of the torsion motor 31 is fixed to the base, thereby rotatably connecting the torsion motor 31 to the worktable 1. The rotary motor 211 drives the base of the torsion motor 31 to rotate, thereby bending the twisted heating wire to 90°.

[0037] Reference Figure 2 , Figure 3 and Figure 4 A sensor-activated start switch 25 is installed on the base 21. The sensor-activated start switch 25 can be a photoelectric sensor, which includes a laser emitter and a laser receiver. When the heating wire is hung on the hook 32 and clamped in the clamping assembly 23, the photoelectric sensor emits an electrical signal, detecting the position of the two clamping parts on the clamping assembly 23, thus determining whether the clamping assembly 23 has clamped the heating wire. The user can control the torsion motor 31 and the rotary motor 211 to operate sequentially and cause the shearing blade 24 to cut the heating wire. The sensor-activated start switch 25 is used to detect whether the heating wire is placed in the clamping assembly 23. When the two moving parts on the clamping assembly 23 are located on one side of the sensor-activated start switch 25, it indicates that the two moving parts of the clamping assembly 23 are not in contact with each other, and the heating wire to be torsion is not connected to the torsion mechanism 3, meaning the end of the heating wire is not clamped in the clamping assembly 23. At this time, the rotary motor 211 and the torsion motor 31 cannot operate. When the user installs the heating wire, the rotary motor 211 and the torsion motor 31 remain stationary, thereby improving safety.

[0038] Reference Figure 3 The shearing mechanism 4 is located between the feeding mechanism 2 and the torsion mechanism 3. The shearing mechanism 4 is used to cut the annular structure connected to the hook 32 on the torn heating wire. A drive component 41 is provided on the shearing mechanism 4. The drive component 41 can be a pneumatic slide rail. The shearing mechanism 4 is mounted on the mover of the drive component 41, which drives the shearing mechanism 4 to move towards or away from the heating wire. When the torsion mechanism 3 torsional the heating wire, the shearing mechanism 4 can approach and cut the heating wire. After the heating wire is processed, the drive component 41 can drive the shearing mechanism 4 away from the feeding mechanism 2 and the torsion mechanism 3. At this time, the user can pull out the end of the heating wire coil and connect it to the torsion mechanism 3, reducing the chance of the shearing mechanism 4 scratching the user.

[0039] Reference Figure 3 The drive component 41 is equipped with a slide rail 42, the length direction of which is perpendicular to the length direction of the drive component 41. The slide rail 42 is fixed on the worktable 1, and the drive component 41 is slidably connected to the slide rail 42. The drive component 41 drives the shearing mechanism 4 to slide along the length direction of the slide rail 42, enabling the shearing mechanism 4 to cut different positions on the heating wire, facilitating adjustment of the length of the cut heating wire. The drive component 41 is equipped with a fixing bolt 43, which is threadedly connected to the drive component 41. The end of the fixing bolt 43 can abut against the slide rail 42, thereby improving the stability of the drive component 41 on the worktable 1 and reducing the probability of positional deviation when the shearing mechanism 4 is performing shearing operations.

[0040] The implementation principle of this application embodiment is as follows: By setting multiple sets of feeding mechanisms 2, torsion mechanisms 3 and shearing mechanisms 4 on the workbench 1, the user can install heating wires on both sides of the workbench 1 in sequence, thereby improving the manufacturing efficiency of heating wires. By setting a fixing rod 22, clamping assembly 23 and shearing blade 24 on the base 21, the heating wire coil can be sleeved on the fixing rod 22, and the heating wire wire pulled out by the heating wire coil can be hung on the hook 32. The torsion motor 31 can drive the hook 32 to rotate, thereby achieving the effect of torsion of the heating wire. The torsioned heating wire is bent to 90° by the rotation mechanism. The two ends of the heating wire are cut by the shearing blade 24 and the shearing mechanism 4 respectively, thereby obtaining a heating wire product with a regular shape and improving manufacturing efficiency.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
