Description

Technical Field

[0001] The invention belongs to the field of folding machines, in particular to a folding machine used for folding the edges of Invar steel. Background Art

[0002] Invar steel is a nickel-iron alloy composed of 36% nickel, 63.8% iron, and 0.2% carbon. It has an extremely low thermal expansion coefficient and can maintain a fixed length over a wide temperature range. Its thermoelastic coefficient is zero. Therefore, Invar steel has the advantages of a small expansion coefficient, low strength and hardness, low thermal conductivity, and high plasticity and toughness. It is widely used in sealing materials for electronic components, precision instruments and instrument parts, LNG (liquefied natural gas) carriers, and other fields.

[0003] Existing Invar steel is often subjected to a folding process when in use, and folding requires a folding machine. The existing folding machine for folding Invar steel includes a frame, on which a feeding device for fixing the Invar steel coil, a pressing and pulling device for pressing and supporting the Invar steel, and a forming wheel group for folding the Invar steel are fixed. The above-mentioned pressing and pulling device is composed of a power wheel group and a pressing auxiliary wheel group. The power wheel group includes three power shafts, each power shaft is provided with a power roller, and the three power shafts are linked and driven to rotate by the power device. The above-mentioned forming wheel group is composed of three forming wheels with different angles. During processing, the Invar steel is manually passed from the feeding device to the pressing and pulling device, and is pressed by the power wheel group and the pressing auxiliary wheel group of the pressing and pulling device. The power wheel group provides power for the Invar steel to move forward, and the pressing auxiliary wheel group provides the pressing force The power wheel group drives the Invar steel to move forward through the three forming wheels of the forming wheel group so that the Invar steel is bent and folded in sequence by 30°-60°-90°. However, due to the high precision requirements of the Invar steel, when the clamping force of the clamping auxiliary wheel group is small, the kinetic energy is insufficient when the Invar steel passes the first and second power shafts, and manual pushing is required to make the Invar steel enter the second power shaft. This processing is particularly inconvenient, especially after the machine has been used for a period of time. When the clamping force of the clamping auxiliary wheel group is large, although the Invar steel can pass through the three power shafts smoothly for folding, the surface of the Invar steel will be damaged by pressure. Therefore, the existing Invar steel folding machine urgently needs a folding machine that can automatically adjust the clamping force, so that the initial clamping force is large, so that the Invar steel can smoothly enter the second power shaft and then automatically reduce the clamping force. Summary of the Invention

[0004] In view of the defects of the existing folding machines, the technical problem to be solved by the present invention is to provide an Invar steel folding machine that can automatically adjust the pressing force.

[0005] In order to achieve the above object, according to one aspect of the present invention, the present invention is implemented by the following technical measures: a folding machine with an automatic feeding and force-adding device, comprising:

[0006] A feeding device, the feeding device is used to convey Invar steel;

[0007] The compression and pulling device is used to clamp and pull the Invar steel delivered by the feeding device, and the compression and pulling device is composed of a power wheel group and a compression auxiliary wheel group. The compression auxiliary wheel group is driven up and down by the lifting and clamping power device, so that the compression auxiliary wheel can cooperate with the power wheel group to clamp and convey the Invar steel. The power wheel group includes three power shafts, each of which is provided with a power roller. The three power shafts are linked and driven to rotate by the power device;

[0008] There are two forming wheel sets, each with the same number of wheels. The two forming wheel sets are located on both sides of the pressing and pulling device. The power provided by the forming wheel sets and the pressing and pulling device is used to fold the Invar steel edge.

[0009] A lifting and pressing power device controller, the lifting and pressing power device controller consisting of a control mechanism and a probe, the probe being located on a frame between two power shafts away from the feeding device or on a frame outside the power shaft farthest from the feeding device, the control mechanism being used to control the extrusion force provided by the lifting and pressing power device to the pressing auxiliary wheel assembly, so that the extrusion force of the pressing auxiliary wheel assembly on the Invar steel can be freely adjusted;

[0010] The frame is used to fix the feeding device, the pressing and pulling device, the forming wheel and the lifting and pressing power device controller, and the frame is also provided with a control device to control the operation of the whole machine.

[0011] The present invention relates to a folding machine with an automatic feeding force-adding device. By adding a lifting and pressing power device controller, the lifting and pressing power device has a stronger pressure at the beginning. In this way, the invar steel can pass through the first power shaft to the second power shaft, and is continuously driven to the third power shaft by the power roller on the second power shaft. When the position sensor detects the invar steel, the control mechanism of the lifting and pressing power device controller controls the lifting and pressing power device to reduce the downward pressure (if the position sensor does not detect the passage of the invar steel for a long time, it will continue to work under high pressure). Since it is driven by two sets of power rollers, there will be no problem of too small pulling force. At the same time, because it is automatically controlled, it will be very convenient to process, which solves the problem that the existing invar steel needs to be manually fed when it needs to pass through the first or second power shaft.

[0012] Furthermore, the feeding device includes a fixed rod, a feeding rod and an arc-shaped conveying seat. The fixed rod is for the Yinwa steel coil to be socketed. There are two feeding rods, and the two feeding rods are provided with several relative feeding wheels. There are multiple arc-shaped conveying seats, and each arc-shaped conveying seat is provided with several groups of upper and lower relative conveying pulleys.

[0013] Furthermore, there are three arc-shaped conveying seats arranged in a line. The positions of the three arc-shaped conveying seats can be adjusted, and the inner sides of the arc-shaped conveying seats on both sides are provided with several groups of upper and lower opposite and arc-shaped conveying pulleys, and the middle arc-shaped conveying seat is provided with several single and arc-shaped conveying pulleys on both sides.

[0014] Furthermore, each power shaft is provided with two power rollers, the clamping auxiliary wheel group includes a roller, an auxiliary wheel seat is provided on the roller, and a driven wheel opposite to each power roller is provided on the auxiliary wheel seat. A lifting and clamping power device fixed to the frame is provided on both sides of the roller, and the lifting and clamping power device is a lifting cylinder.

[0015] Furthermore, both sides of the roller pass through the frame, and vertical lifting guide grooves are provided on the frame for the roller to be lifted and lowered.

[0016] Furthermore, both sides of the roller are connected to the frame via tension springs.

[0017] Furthermore, a plurality of bearings are provided at intervals on the roller, and a lifting and pressing power device is provided on the upper end of each bearing. The rollers between the plurality of bearings are threaded shafts, which are threadedly connected to the auxiliary wheel seat, and a turning handle is also provided on one side of the roller.

[0018] Furthermore, the forming wheel group is arranged on the wheel frame, one end of the wheel frame is screwed to a rotating rod, the middle of the rotating rod is a screw rod, the two ends of the rotating rod are smooth rods, and the two ends of the rotating rod are each provided with a bearing seat fixed to the frame, and a bearing is provided in the bearing seat that is sleeved on the rotating rod.

[0019] Furthermore, the lower end of the frame is provided with a lifting support foot.

[0020] Furthermore, a plurality of wheels are provided at the lower end of the frame.

[0021] Compared with the prior art, the advantages of the present invention are that by adding a lifting and compacting power device controller, the power of the lifting and compacting power device can be automatically controlled, which facilitates the transportation of Invar steel, greatly improves the transportation efficiency, and will not damage the surface of Invar steel and cause quality problems.
