Description

Technical Field

[0001] This utility model belongs to the technical field of double-headed torsion spring processing equipment, specifically relating to a high-buffering-function double-headed torsion spring preparation device. Background Technology

[0002] Double-ended torsion springs are springs that rely on their torsional elasticity to generate frictional force to transmit power or motion, and they have a wide range of applications in machinery, automobiles, electrical appliances, medical devices, toys and other fields.

[0003] During the manufacturing process of double-ended torsion springs, to ensure their high buffering capacity, operators use a box-type resistance furnace to process them. The furnace performs quenching and tempering processes, which improves the spring's strength, hardness, elastic limit, and fatigue strength, thus ensuring its high buffering capacity. The box-type resistance furnace has ventilation holes on both sides for heat dissipation. When the furnace is not in use, environmental debris can easily enter through these holes and accumulate inside, potentially affecting its operation.

[0004] Therefore, this invention provides a high-buffering-function double-headed torsion spring manufacturing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-buffering-function double-headed torsion spring manufacturing device, which aims to solve the problem in the prior art that existing box-type resistance furnaces have heat dissipation holes on both sides for heat dissipation. When the box-type resistance furnace is not in use, environmental debris can easily enter the interior of the box-type resistance furnace through the heat dissipation holes and accumulate, causing these debris to affect the operation of the box-type resistance furnace.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-buffering-function double-headed torsion spring manufacturing device, comprising a resistance furnace body, heat dissipation holes on both sides of the resistance furnace body at both ends, mounting brackets on both sides of the resistance furnace body outside the heat dissipation holes, bearings embedded on the inner surfaces of both ends of the mounting bracket at the middle position, a bidirectional screw connecting the two bearings, one end of the bidirectional screw extending into the mounting bracket and fixedly connected to the output end of a motor, the motor being connected to the top surface at the middle position of the mounting bracket, baffle plates threaded through both ends of the bidirectional screw, connecting blocks connected to both ends of the mounting bracket, and a support base connected to the bottom surface of the resistance furnace body.

[0007] In a preferred embodiment of the high-buffering-function double-headed torsion spring manufacturing device of this utility model, the size of the baffle plate is larger than the size of the heat dissipation hole distribution, and the baffle plate and the mounting frame form a sliding connection.

[0008] In a preferred embodiment of the high-buffering double-headed torsion spring preparation device of this utility model, one end of the connecting block extends into the connecting groove, the connecting groove is opened on the front end surface of the mounting block, the mounting block is symmetrically fixedly connected to one side surface of the resistance furnace body, and fixing bolts are connected through one side surface at both ends of the connecting block, and the other end of the fixing bolts forms a threaded connection with the mounting block.

[0009] As a preferred embodiment of the high-buffering double-headed torsion spring manufacturing device of this utility model, a movable plate is slidably connected to the inner surface of the support base. Universal wheels are connected to the bottom surface of the four corners of the movable plate, and protrusions are connected to the two side surfaces at both ends of the movable plate. One end of the protrusion extends into the interior of the slide groove. The slide groove is symmetrically opened on the top surface of the support base, and an electric push rod is connected to the bottom surface of the inner side of the slide groove. The movable end of the electric push rod is connected to the bottom surface of the protrusion.

[0010] As a preferred embodiment of the high-buffering-function double-headed torsion spring manufacturing device of this utility model, the support base has limit holes on both sides, and a butterfly bolt is connected through the limit holes. The moving plate has threaded holes on both sides, and the butterfly bolt can form a threaded connection between the limit holes and the threaded holes.

[0011] In a preferred embodiment of the high-buffering-function double-headed torsion spring manufacturing device of this utility model, the motor and the electric push rod are electrically connected to an external power source via a control switch.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention features baffles that allow the motor to be started when the resistance furnace body is not in use. The motor's output drives the bidirectional screw to rotate, and the two baffles on the bidirectional screw move toward the heat dissipation holes at both ends of the resistance furnace body. This allows the baffles to protect the heat dissipation holes, preventing them from being exposed to the environment and avoiding debris from accumulating inside the resistance furnace body.

[0014] This invention utilizes an electric push rod to move a protrusion downwards, causing the protrusion to carry a movable plate downwards within the support base. At this point, the casters at the bottom of the movable plate can contact the ground and support the resistance furnace body. The position of the movable plate is then fixed with a butterfly bolt. This allows the operator to move the resistance furnace body using the casters, preventing manual handling and facilitating the movement of the preparation device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a high-buffering-function double-headed torsion spring preparation device, including a resistance furnace body 1, the resistance furnace body 1 is a muffle furnace box type resistance furnace, heat dissipation holes 2 are provided on both sides of the two ends of the resistance furnace body 1, and mounting brackets 3 are provided on both sides of the resistance furnace body 1 outside the heat dissipation holes 2. Bearings 4 are embedded on the inner surfaces of both ends of the mounting bracket 3 at the middle position. A bidirectional screw 5 is connected between the two bearings 4. One end of the bidirectional screw 5 extends into the mounting bracket 3 and is fixedly connected to the output end of the motor 6. The motor 6 is connected to the top surface at the middle position of the mounting bracket 3. A baffle plate 7 is threaded through both ends of the bidirectional screw 5. Connecting blocks 8 are connected to both ends of the mounting bracket 3. A support base 12 is connected to the bottom surface of the resistance furnace body 1.

[0023] Preferably, the size of the shield 7 is larger than the size of the heat dissipation holes 2, and the shield 7 and the mounting bracket 3 form a sliding connection.

[0024] In actual use, the shield 7 can slide inside the mounting bracket 3 so that the shield 7 can completely block the heat dissipation hole 2 after being moved.

[0025] Preferably, one end of the connecting block 8 extends into the connecting groove 9, the connecting groove 9 is opened on the front end surface of the mounting block 10, the mounting block 10 is symmetrically fixedly connected to one side surface of the resistance furnace body 1, and a fixing bolt 11 is connected through one side surface at both ends of the connecting block 8, and the other end of the fixing bolt 11 is threadedly connected to the mounting block 10.

[0026] In practical use, slide the connecting blocks 8 at both ends of the mounting bracket 3 into the connecting grooves 9 on the mounting block 10, and then use the fixing bolts 11 to pass through the connecting blocks 8 and screw them into the mounting block 10. This will fix the position of the connecting blocks 8 in the connecting grooves 9, allowing the mounting bracket 3 to be installed on the mounting block 10. The mounting bracket 3 can be installed on both sides of the resistance furnace body 1. At this time, the heat dissipation holes 2 will be located inside the mounting bracket 3.

[0027] Preferably, a movable plate 13 is slidably connected to the inner surface of the support base 12. Universal wheels 14 are connected to the bottom surface of the four corners of the movable plate 13. Protrusions 15 are connected to both sides of the movable plate 13. One end of the protrusion 15 extends into the interior of the slide groove 16. The slide groove 16 is symmetrically opened on the top surface of the support base 12. An electric push rod 17 is connected to the bottom surface of the inner side of the slide groove 16. The movable end of the electric push rod 17 is connected to the bottom surface of the protrusion 15.

[0028] In actual use, start the electric push rod 17, so that the movable end of the electric push rod 17 drives the protrusion 15 to move in the slide groove 16. At this time, the protrusion 15 will move the moving plate 13 inside the support seat 12, so that the moving plate 13 can move out or retract into the support seat 12 with the caster wheel 14.

[0029] Preferably, the support base 12 has limit holes 18 on both sides, and a butterfly bolt 19 is connected through the limit holes 18. The moving plate 13 has threaded holes 20 on both sides, and the butterfly bolt 19 can form a threaded connection between the limit holes 18 and the threaded holes 20.

[0030] In practical use, when the threaded hole 20 and the limiting hole 18 on the movable plate 13 coincide, the butterfly bolt 19 is inserted through the limiting hole 18 and screwed into the threaded hole 20, so that the position of the movable plate 13 can be fixed inside the support base 12, thereby improving the stability of the movable plate 13.

[0031] Preferably, the motor 6 and the electric push rod 17 are electrically connected to an external power source via a control switch.

[0032] In actual use, the motor 6 and the electric push rod 17 can be controlled by a switch.

[0033] Working principle: When using this high-buffering double-headed torsion spring preparation device, slide the connecting blocks 8 at both ends of the mounting frame 3 into the connecting grooves 9 on the mounting block 10, and then use fixing bolts 11 to pass through the connecting blocks 8 and screw them into the mounting block 10. This fixes the position of the connecting blocks 8 in the connecting grooves 9, allowing the mounting frame 3 to be installed on the mounting block 10. At this time, the heat dissipation holes 2 will be located inside the mounting frame 3. When the resistance furnace body 1 needs to prepare the double-headed torsion spring, open the door of the resistance furnace body 1, place the wound double-headed torsion spring blank into the resistance furnace body 1, close the door, connect the power supply to the resistance furnace body 1, and after setting the parameters, the resistance furnace body 1 will control the resistance heating element through the temperature control system to achieve automatic heating, heat preservation, and cooling. The process of quenching and tempering of the double-headed torsion spring blank is completed, which improves the strength, hardness, elastic limit, and fatigue strength of the double-headed torsion spring, giving it excellent high buffering function. When the resistance furnace body 1 is not in use, the motor 6 can be started by controlling the switch, allowing the output end of the motor 6 to drive the bidirectional screw 5 to move in the bearing 4. At this time, the two baffles 7 on the bidirectional screw 5 will slide towards the heat dissipation holes 2 inside the mounting bracket 3. When the two baffles 7 contact the inner end surfaces of the mounting bracket 3, the two baffles 7 can completely block the heat dissipation holes 2 opened at both ends of the side of the resistance furnace body 1, preventing the heat dissipation holes 2 from being exposed to the environment and preventing debris from entering the resistance furnace body 1 through the heat dissipation holes 2. Internal accumulation ensures the cleanliness of the inside of the resistance furnace body 1. When the resistance furnace body 1 is used again, the output end of the motor 6 drives the bidirectional screw 5 to rotate in the opposite direction. At this time, the two baffles 7 on the bidirectional screw 5 will move closer to each other, so that the two baffles 7 no longer block the heat dissipation holes 2, ensuring the normal use of the heat dissipation holes 2. Secondly, when the resistance furnace body 1 needs to be moved, the electric push rod 17 is activated by the control switch, so that the movable end of the electric push rod 17 drives the protrusion 15 to move downward in the slide groove 16. At this time, the protrusion 15 will carry the moving plate 13 to move downward inside the support base 12. When the protrusion 15 can no longer move downward, the universal wheel 14 at the bottom of the moving plate 13 will contact the ground and support the resistance furnace body 1. At this time, the moving plate 13 will move downward. The threaded hole 20 on plate 3 will coincide with the limiting hole 18. By screwing the butterfly bolt 19 through the limiting hole 18 into the threaded hole 20, the position of the moving plate 13 can be fixed inside the support base 12. At this time, the operator can move the resistance furnace body 1 through the universal wheel 14 to prevent the operator from manually moving it, which brings convenience to the movement of the preparation device. When the resistance furnace body 1 is moved to the designated position, the butterfly bolt 19 can be screwed again to separate one end of the butterfly bolt 19 from the threaded hole 20. At this time, the movable end of the electric push rod 17 can drive the moving plate 13 to move upward through the protrusion 15, so that the universal wheel 14 retracts into the inside of the support base 12, allowing the support base 12 to support the resistance furnace body 1 and ensure the stability of the resistance furnace body 1 when it is placed and used.
