Description

Technical Field

[0001] This utility model relates to the field of spring steel wire cutting technology, specifically a cutting device for processing automotive suspension spring steel wire. Background Technology

[0002] Spring steel wire is a type of steel wire used to make springs or wire profiles. Depending on the application of the spring, there are various types of spring steel wire required for making springs, such as spring steel wire for shock absorbers, spring steel wire for suspension springs, spring steel wire for engine valves, and spring steel wire for camera shutters, etc. Although there is no unified standard classification name, the quality requirements for these steel wires are different.

[0003] According to a publicly disclosed cutting device for processing automotive suspension spring steel wire (publication number: CN219966281U), the above application ensures that when the cutting device cuts the steel wire, the cross-section of the steel wire is flat, effectively avoiding the problem of uneven cross-section leading to poor finished product quality. Furthermore, by providing a fixed arm, a top block, a support block, a limiting cylinder device, and a limiting seat, the limiting of one end of the spring steel wire can be completed without manual straightening, ensuring that the spring steel wire is sufficiently stable after being cut by the cutting device and is not easily detached from the cutting device.

[0004] However, in actual use, the cut steel wires fall into the collection trolley under the action of the cylinder and the push seat. But the gap between the worktable and the collection table is too large, causing the processed steel wires to fall into the gap, affecting the collection efficiency. In view of this, we propose a cutting device for processing automotive suspension spring steel wires. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for processing automotive suspension spring steel wire, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for processing automotive suspension spring steel wire, comprising a worktable, a side plate fixedly connected to the side of the worktable, a bracket fixedly connected to the bottom of the worktable, a control panel provided on the side wall of the side plate, a rolling roller rotatably connected to the upper surface of the worktable, a limit block fixedly connected to the inner wall of the side plate, a first rotating motor fixedly connected to the top of the limit block, a reciprocating threaded rod fixedly connected to the output end of the first rotating motor, a connecting block threadedly connected to the reciprocating threaded rod, a cutting disc fixedly installed at the bottom of the connecting block, a collecting groove slidably connected to the side plate, and a conveying mechanism for transporting the cut spring steel wire provided on the side plate, the conveying mechanism comprising:

[0007] A support plate is fixedly connected to a side plate. A second rotating motor is fixedly installed on the top of the support plate. A drive wheel is fixedly connected to the output end of the second rotating motor. A transmission wheel is rotatably connected to the inner wall of the side plate near the drive wheel. A transmission belt is driven by the drive wheel.

[0008] Preferably, the conveying mechanism further includes a small gear, the output end of the rotating motor is fitted with a small gear, a rotating rod is rotatably connected above the small gear on the side plate, a large gear is fitted on the outer wall of the rotating rod, and a cleaning roller is fixedly connected to the end of the rotating rod away from the large gear.

[0009] Preferably, the drive wheel is rotatably connected to the inner wall of the side plate, and the transmission wheel is the same size as the drive wheel, which facilitates driving the transmission belt.

[0010] Preferably, two sets of rollers are provided on the worktable, and the two sets of rollers are mirror-symmetrical on the worktable to limit the spring steel wire.

[0011] Preferably, the large gear meshes with the small gear, and there is an appropriate gap between the cleaning roller and the transmission belt to facilitate the passage of the cut spring.

[0012] Preferably, the inner wall of the side plate is provided with a sliding mechanism for moving the collection groove. The sliding mechanism includes a slider, which is fixedly connected to the collection groove. A groove is provided at one end of the side plate near the collection groove. A return spring is fixedly connected to the top of the groove, and a protrusion is fixedly connected to the return spring.

[0013] Preferably, the size of the bump is adapted to the size of the groove, and the surface of the bump is smooth to facilitate the slider to press the bump.

[0014] Compared with the prior art, this utility model provides a cutting device for processing automotive suspension spring steel wire, which has the following advantages:

[0015] 1. This cutting device for processing automotive suspension spring steel wires, through the setting of a transmission mechanism, uses a rotating motor to drive the drive wheel to rotate, which in turn drives the driven wheel and the transmission belt to rotate, thereby realizing the conveying of the cut spring steel wires. The cut spring steel wires are sent into the collection trough, and after falling onto the transmission belt, they move. The cleaning roller above rotates in the opposite direction under the gear transmission to brush the surface of the steel wires, removing metal debris and oil stains generated during the cutting process. This solves the technical problem of inconvenient collection of spring steel wires and improves product quality.

[0016] 2. This cutting device for processing automotive suspension spring steel wires utilizes a sliding mechanism located on the inner wall of the side plate to facilitate the placement and removal of the collection trough. The collection trough is pushed in and pulled out by the movement of a slider within a chute. When the slider moves into the chute, a return spring helps the protrusion pop out and limits the slider, ensuring the collection trough remains stable during material receiving. When cleaning is required, a small pulling force is applied to compress and retract the protrusion, smoothly pulling out the collection trough and ensuring the stability of the collection process, thus improving the efficiency of placing and removing the collection trough.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a cutting device for processing automotive suspension spring steel wire, including a worktable 1, a side plate 2 fixedly connected to the side of the worktable 1, a bracket 3 fixedly connected to the bottom of the worktable 1, a control panel 4 provided on the side wall of the side plate 2, a rolling roller 5 rotatably connected to the upper surface of the worktable 1, a limit block 6 fixedly connected to the inner wall of the side plate 2, a rotating motor 7 fixedly connected to the top of the limit block 6, a reciprocating threaded rod 8 fixedly connected to the output end of the rotating motor 7, a connecting block 9 threadedly connected to the reciprocating threaded rod 8, a cutting blade 10 fixedly installed at the bottom of the connecting block 9, a collection groove 11 slidably connected to the side plate 2, and a conveying mechanism 12 for transporting the cut spring steel wire provided on the side plate 2. The conveying mechanism 12 includes: a support plate 121, a rotating motor 122, a pinion 123, a rotating rod 124, a large gear 125, a drive wheel 126, a transmission wheel 127, a transmission belt 128, and a cleaning roller 129.

[0023] In an embodiment of this utility model, a support plate 121 is fixedly connected to a side plate 2. A second rotating motor 122 is fixedly installed on the top of the support plate 121. A drive wheel 126 is fixedly connected to the output end of the second rotating motor 122. A transmission wheel 127 is rotatably connected to the inner wall of the side plate 2 near the drive wheel 126. A transmission belt 128 is rotatably connected to the drive wheel 126. A small gear 123 is sleeved on the output end of the second rotating motor 122. A rotating rod 124 is rotatably connected above the small gear 123 on the side plate 2. A large gear 125 is sleeved on the outer wall of the rotating rod 124. A cleaning roller 129 is fixedly connected to the end of the rotating rod 124 away from the large gear 125.

[0024] In one embodiment of this utility model, a side plate 2 is fixedly connected to the side of the workbench 1 by welding. A bracket 3 is welded to the four corners of the bottom of the workbench 1. A control panel 4 is installed on the side wall of the side plate 2. The control panel 4 has a touch screen and control buttons to control the start of the first rotating motor 7 and the second rotating motor 122. A rolling roller 5 is rotatably connected to the upper surface of the workbench 1. The surface of the rolling roller 5 has an annular groove that matches the diameter of the steel wire to limit and fix the steel wire, so as to prevent the steel wire from moving during the cutting process and causing cutting problems. A limit block 6 is welded to the inner wall of the side plate 2. The first rotating motor 7 is fixedly installed on the top of the limit block 6 by bolts. The output shaft of the first rotating motor 7 is connected to a reciprocating threaded rod 8. The surface of the reciprocating threaded rod 8 is machined with bidirectional threads to form a threaded pair connection with the connecting block 9. A cutting blade 10 is fixedly installed on the bottom of the connecting block 9 by a pressure plate. The cutting blade 10 is made of hard alloy material and cuts the steel wire. A guide rail mechanism is provided on the inner side of the side plate 2 to form a sliding connection with the collection groove 11.

[0025] In addition, a conveying mechanism 12 is provided, which includes a support plate 121. The support plate 121 is fixed to the side plate 2 by welding. A second rotating motor 122 is installed on the top of the support plate 121. The output end of the second rotating motor 122 is connected to and fixed to the drive wheel 126. A transmission wheel 127 is rotatably connected to the inner wall of the side plate 2. The drive wheel 126 and the transmission wheel 127 are connected by a transmission belt 128. The conveying mechanism 12 is also provided with a small gear 123, which is sleeved on the output shaft of the second rotating motor 122. A rotating rod 124 is rotatably connected to the side plate 2 above the small gear 123 through a bearing seat. A large gear 125 is sleeved on the rotating rod 124. The large gear 125 meshes with the small gear 123 for transmission. The rotating rod 124 is connected to a cleaning roller 129. The surface of the cleaning roller 129 is covered with wire brush material to clean the cut wire and provide a basic guarantee for subsequent work.

[0026] In addition, the inner wall of the side plate 2 is provided with a sliding mechanism 13 for moving the collection groove 11. The sliding mechanism 13 includes a slider 131, which is fixedly connected to the collection groove 11. A groove 132 is provided at one end of the side plate 2 near the collection groove 11. The slider 131 can slide left and right along the groove 132. A return spring 133 is fixedly connected to the top of the groove 132. A protrusion 134 is fixedly connected to the end of the return spring 133. In the natural state, the elastic force of the return spring 133 pushes the protrusion 134 out. When the collection groove 11 is pushed forward, the slider 131 squeezes the protrusion 134 to make it retract. After passing the protrusion 134, the protrusion 134 pops out under the action of the spring force, forming a limit and fixing the collection groove 11.

[0027] In this invention, during use, the spring steel wire passes between two sets of mirror-symmetrically arranged rolling rollers 5 on the workbench 1. The rolling rollers 5 limit and fix the steel wire. When the steel wire reaches the predetermined length, the first rotating motor 7 starts, driving the reciprocating threaded rod 8 to rotate, which in turn moves the connecting block 9 and the bottom cutting blade 10 downwards to cut the steel wire. The cut steel wire segment moves to the lower conveying mechanism 12, and the second rotating motor 122 starts, driving the transmission belt 128 through the drive wheel 126 and the transmission wheel 127 to transport the steel wire segment. At the same time, the small gear 123 at the output end of the second rotating motor 122 drives the large gear 125 and the rotating rod 124 to rotate. Rod 124 drives cleaning roller 129 to rotate at high speed, brushing the surface of the steel wire segment being conveyed. The steel wire segment eventually falls into the collection trough 11. The collection trough 11 is conveniently positioned and picked up / dropped through sliding mechanism 13. When the collection trough 11 is pushed forward along side plate 2, slider 131 fixed on it slides in slide groove 132 and squeezes protrusion 134 to compress return spring 133. When the collection trough 11 is pushed to the working position, protrusion 134 pops out under the action of return spring 133, forming a mechanical limit to ensure that the collection trough 11 remains stable during material receiving. When replacement is needed, pull back collection trough 11 to retract protrusion 134 and remove collection trough 11.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
