Description

Technical Field

[0001] This utility model relates to the technical field of torsion spring bending equipment, specifically to a torsion spring bending device. Background Technology

[0002] Torsion springs, generally referring to torsion springs, are a type of spring, and one of the more complex types. They come in a variety of forms and are quite flexible. When other components rotate around the center of the torsion spring, the torsion spring pulls them back to their initial position. In the production of existing torsion springs, the raw materials for torsion spring production need to be bent, which requires a bending machine to bend the raw materials.

[0003] In existing torsion spring bending machines, the bent torsion springs are cut by a cutting blade and then fall to the ground naturally. Directly falling to the ground can easily damage the surface of the torsion springs, and the falling position of the torsion springs varies depending on the cutting position. Therefore, it is inconvenient to collect the finished torsion springs. Although some manufacturers place a collection box at the bottom of the torsion spring bending machine, when the tail end of the torsion spring is cut off and it falls, the cut torsion spring will be thrown and scattered, and thus cannot enter the collection box. To solve the above problems, a torsion spring bending device is proposed to solve the above problems. Utility Model Content

[0004] In view of this, the present invention provides a bending device for torsion springs. The present invention protects the left and right sides of the discharge chamber through a baffle assembly and the front of the discharge chamber through an observation window, so that the falling torsion springs can only enter the discharge bin through the discharge hopper and finally enter the collection box through the discharge nozzle. Then, the electric push rod is controlled to push the slider to the opening, so that the torsion spring can be taken out, preventing the cut torsion springs from being thrown away and scattered, thus facilitating the collection of torsion springs.

[0005] To solve the above-mentioned technical problems, this utility model provides a bending device for torsion springs, including a support plate on a support frame, a wire outlet nozzle at the bottom front end of the support plate, a bending head at the upper front side of the wire outlet nozzle, cutting devices on both sides of the wire outlet nozzle, a material discharge chamber at the bottom of the bending head, a hopper at the bottom of the material discharge chamber, a baffle assembly on the left and right sides of the material discharge chamber, a material discharge bin at the discharge end of the material discharge bin, a slide rail at the bottom of the material discharge bin, a slider slidably mounted on the slide rail, and a collection box fixedly mounted on the slider.

[0006] Each baffle assembly includes a first inclined plate connected to the top wall of the hopper. The first inclined plate facilitates the sliding of the torsion spring into the hopper. A vertical plate is fixedly installed on the upper part of the first inclined plate to prevent the torsion spring from flying off and falling, so that the torsion spring cut by the cutting device can fall into the hopper.

[0007] Each vertical plate is hinged to a second inclined plate on its upper surface. The second inclined plate is used to place the torsion spring to be thrown out from the top of the discharge chamber.

[0008] An observation window is hinged between the front of the two vertical plates, which is used to observe the working conditions inside the material discharge chamber.

[0009] The discharge end of the discharge hopper is connected to a discharge nozzle, which is used to guide the torsion springs in the discharge hopper into the collection box. The discharge nozzle is hollow trapezoidal, and an installation plate is fixedly installed on one side wall of the discharge nozzle. The installation plate is used to install a level gauge and also to connect the discharge nozzle to the level gauge. The level gauge is installed on the installation plate and is used to detect the height of the torsion springs piled up in the collection box.

[0010] One end of the slider is equipped with an electric push rod, which is used to push the slider to move on the slide rail, thereby driving the collection box and the torsion spring installed inside it. The drive end of the electric push rod passes through the side wall of the bottom of the support frame. The slider has an opening on the side opposite to the electric push rod, which facilitates the collection box to enter and exit the bottom of the support frame. The opening passes through the side wall of the bottom of the support frame.

[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. After the torsion spring is cut by the cutting device, the left and right sides of the discharge chamber are protected by the baffle assembly, and the front of the discharge chamber is protected by the observation window. This ensures that the falling torsion spring can only enter the discharge bin through the discharge hopper, and finally enter the collection box through the discharge nozzle. Then, the electric push rod is controlled to push the slider to the opening, so that the torsion spring can be taken out. This prevents the cut torsion spring from being thrown away and scattered, thus facilitating the collection of the torsion spring.

[0012] 2. The observation window is used to view the working conditions inside the material discharge chamber, thus facilitating subsequent maintenance work.

[0013] 3. The discharge nozzle is used to guide the torsion spring in the discharge bin into the collection box. The mounting plate is also used to connect the discharge nozzle to the level gauge. The level gauge is used to detect the height of the torsion spring in the collection box. When the collection box reaches a certain material height, the electric push rod drives the slide block to push the collection box out of the opening, thus facilitating material removal.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0017] like Figure 1-5 As shown: This embodiment provides a bending device for a torsion spring, including a support plate 101 mounted on a support frame 100. The support plate 101 is welded or bolted to the bearing surface of the support frame 100. A wire outlet nozzle 102 is provided at the bottom front end of the support plate 101. A feeding mechanism and a straightening mechanism are connected to the rear end of the wire outlet nozzle 102. A bending head 103 is provided on the upper front side of the wire outlet nozzle 102. A motor is rotatably mounted on the upper end of the bending head 103. Cutting devices 104 are provided on both sides of the wire outlet nozzle 102.

The bottom of the support plate and the hopper 301 is welded to the bearing surface of the support frame 100 and welded to the discharge chamber 204. A baffle assembly 200 is set on each of the left and right sides of the discharge chamber 300. The discharge end of the hopper 301 is connected to the discharge chamber 204. The discharge chamber 204 is welded to the bottom of the bearing surface of the support frame 100. A slide rail 500 is set at the bottom of the discharge chamber 204. The slide rail 500 is fixedly installed on the bottom of the support frame 100 by bolts. A slider 501 is slidably set on the slide rail 500. The slider 501 is slidably adapted to the slide rail 500. A collection box 502 is fixedly set on the slider 501. The collection box 502 is detachably connected to the slider 501, so as to facilitate the handling of the collection box 502 and the removal of the torsion spring.

[0018] In use, after the torsion spring is cut by the cutting device 104, the left and right sides of the discharge chamber 300 are protected by the baffle assembly 200, and the front of the discharge chamber 300 is protected by the observation window 302. This ensures that the falling torsion spring can only enter the discharge bin 204 through the discharge hopper 301, and finally enter the collection box 502 through the discharge nozzle 303. Then, the electric push rod 400 is controlled to push the slider 501 to the opening 401, so that the torsion spring can be taken out. This prevents the cut torsion spring from being thrown away and scattered, thus facilitating the collection of the torsion spring.

[0019] This embodiment provides a bending device for torsion springs. like Figure 1 , 2 As shown in Figures 3 and 5: Each baffle assembly 200 includes a first inclined plate 201 connected to the top wall of the hopper 301. The first inclined plate 201 is welded to the hopper 301. The first inclined plate 201 facilitates the torsion spring to slide into the hopper 301. A vertical plate 202 is fixedly provided on the upper part of the first inclined plate 201. The vertical plate 202 is welded to the first inclined plate 201. The vertical plate 202 is used to prevent the torsion spring from flying off and falling, so that the torsion spring cut by the cutting device 104 can fall into the hopper 301. A second inclined plate 203 is hinged to the upper surface of each vertical plate 202. The second inclined plate 203 is hinged to the vertical plate 202 through a hinge. The second inclined plate 203 is used to place the torsion spring from the top of the discharge chamber 300.

[0020] Its effects are as follows: the first inclined plate 201 facilitates the torsion spring to slide into the hopper 301, the vertical plate 202 is used to prevent the torsion spring from flying and falling, so that the torsion spring cut by the cutting device 104 can fall into the hopper 301, and the second inclined plate 203 is used to prevent the torsion spring from being thrown from the top of the discharge cavity 300, so that the guard assembly 200 protects the left and right sides of the discharge cavity 300.

[0021] like Figure 1 , 2 As shown in Figures 3 and 5: An observation window 302 is hinged between the front sides of the two vertical plates 202. The observation window 302 can be made of transparent acrylic sheet and hinged to the vertical plate 202, so as to facilitate opening the material discharge cavity 300. The observation window 302 is used to observe the working conditions inside the material discharge cavity 300.

[0022] Its function is as follows: the observation window 302 is used to observe the working conditions inside the material discharge chamber 300.

[0023] like Figure 1 , 2As shown in Figures 3, 4, and 5: A discharge nozzle 303 is connected to the discharge end of the discharge bin 204. The discharge bin 204 is a hollow rectangle. The discharge nozzle 303 is welded to the discharge bin 204. The discharge nozzle 303 is used to guide the torsion springs in the discharge bin 204 into the collection box 502. The discharge nozzle 303 is a hollow trapezoid. An mounting plate 304 is fixedly installed on one side wall of the discharge nozzle 303. The mounting plate 304 is welded to the discharge nozzle 303. The mounting plate 304 is used to install a level gauge 305. The mounting plate 304 is also used to connect the discharge nozzle 303 and the level gauge 305. The level gauge 305 is installed on the mounting plate 304. The outer shell of the level gauge 305 is fixed to the mounting plate 304 by bolts. The probe of the level gauge 305 faces the inside of the collection box 502. The level gauge 305 is used to detect the height of the torsion springs piled up inside the collection box 502.

[0024] Its effect is as follows: the discharge nozzle 303 is used to guide the torsion spring in the discharge bin 204 into the collection box 502. The mounting plate 304 is also used to connect the discharge nozzle 303 to the level gauge 305. The level gauge 305 is used to detect the height of the torsion spring in the collection box 502. When the collection box 502 reaches a certain material height, the electric push rod 400 drives the slide block 501 to push out the collection box 502 out of the opening 401.

[0025] like Figure 1 , 3 As shown in Figure 5: One end of the slider 501 is provided with an electric push rod 400.

The opening 401 facilitates the collection box 502 to enter and exit the bottom of the support frame 100. The opening 401 passes through the side wall of the bottom of the support frame 100.

[0026] Its effect is as follows: the electric push rod 400 is used to push the slider 501 to move on the slide rail 500, thereby driving the collection box 502 and the torsion spring installed inside it. The opening 401 facilitates the collection box 502 to enter and exit the bottom of the support frame 100.

[0027] Working principle: After the torsion spring is cut by the cutting device 104, the left and right sides of the discharge chamber 300 are protected by the baffle assembly 200, and the front of the discharge chamber 300 is protected by the observation window 302. This ensures that the falling torsion spring can only enter the discharge bin 204 through the discharge hopper 301, and finally enter the collection box 502 through the discharge nozzle 303. Then, the electric push rod 400 is controlled to push the slider 501 to the opening 401, so that the torsion spring can be taken out. This prevents the cut torsion spring from being thrown away and scattered, thus facilitating the collection of the torsion spring.
