Description

Technical Field

[0001] The invention belongs to the technical field of non-standard equipment and relates to steel wire hose production equipment, in particular to an automatic pipe opening repairing machine for steel wire hose. Background Art

[0002] Steel wire hoses, especially rubber steel wire hoses, can be extended from one meter to seven meters. Due to their excellent ductility, they are used in vacuum cleaners as dust suction hoses.

[0003] In actual use, the steel wire hose needs to be cut to length manually or using cutting equipment. The rubber cut and / or steel wire cut of the new pipe mouth formed by manual or automatic cutting of the steel wire hose are uneven, which seriously affects the assembly effect of the steel wire hose and other adapters. Therefore, the pipe mouth of the steel wire hose needs to be trimmed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a machine which can trim the pipe opening of a steel wire hose.

[0005] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0006] The automatic pipe end trimming machine for a steel wire hose comprises two sets of pipe end trimming and cutting devices arranged side by side and in opposite directions, and a transfer device located between the two sets of pipe end trimming and cutting devices;

[0007] The pipe mouth trimming device comprises two parallel and co-rotating rollers, a rubber cutting tool, a wire cutting tool, a pipe body clamping mechanism, a pipe body guiding mechanism and a pipe mouth clamping mechanism; the wire cutting tool and the pipe body clamping mechanism are located above the rollers, the pipe body clamping mechanism is driven to translate by a translation drive member, and is driven to elevate by a lifting drive member, and the wire cutting tool is driven to elevate by a lifting drive member;

[0008] The tube body guiding mechanism, the tube mouth clamping mechanism and the rubber cutting tool are located at the same end of the roller, and the tube body guiding mechanism is located between the roller and the tube mouth clamping mechanism; the tube mouth clamping mechanism includes two clamping plates that can be gathered inward and opened outward; the tube body guiding mechanism includes two guide blocks that can be gathered inward and opened outward, and a sensor for detecting the position of the tube mouth, and the thread grooves arranged on the inner sides of the two guide blocks form a threaded hole matching the tube body thread of the stretched steel wire hose after the two guide blocks are gathered;

[0009] The transfer device includes a V-shaped plate, a bracket and a lifting cylinder, wherein the bracket is fixed between two sets of pipe mouth trimming devices, the V-shaped plate is hinged on the top of the bracket, and the lifting cylinder acts as a power source to drive the V-shaped plate to rotate and swing to both sides;

[0010] A lifting plate is arranged between two supporting rollers of the pipe mouth trimming device, and a lifting cylinder for driving the lifting plate to be lifted and lowered is installed below the lifting plate.

[0011] In the technical solution, two groups of pipe opening trimming devices trim the two pipe openings of the steel wire hose respectively, and the transfer device transfers the steel wire hose from one group of pipe opening trimming devices to the other group of pipe opening trimming devices.

[0012] The trimming process of the pipe mouth trimming device is as follows:

[0013] 1. The steel wire hose is placed on the roller, and the pipe mouth clamping mechanism clamps one end of the steel wire hose;

[0014] 2. The tube body clamping mechanism moves downward to clamp the tube body of the steel wire hose and stretch the tube body backward;

[0015] 3. The two guide blocks of the tube body guide mechanism gather inward to clamp the steel wire hose;

[0016] 4. The pipe body clamping mechanism and the pipe mouth clamping mechanism release the steel wire hose, and the roller drives the steel wire hose to rotate. The hose rotates backward under the guidance of the threaded hole of the pipe body guide mechanism;

[0017] 5. When the sensor detects the cutting position of the steel wire, the roller drives the hose to rotate at least one more circle. During this process, the rubber cutting tool extends out to cut the rubber;

[0018] 6. After the wire hose stops rotating, the wire cutting tool moves downward to cut the wire.

[0019] The transfer process of the steel wire hose in the two sets of pipe mouth trimming devices is as follows:

[0020] 1. After the steel wire of the steel hose is cut, the lifting cylinder drives the V-shaped plate to tilt to one side;

[0021] 2. The lifting plate rises upward to push the steel hose off the roller, and then the steel hose slides into the inclined V-shaped plate;

[0022] 3. The lifting cylinder drives the V-shaped plate to tilt to the other side, and the wire hose slides onto another set of rollers.

[0023] The automatic pipe opening repairing machine for steel wire hose according to the present invention may also have the following additional technical features:

[0024] Furthermore, each set of pipe opening trimming devices also includes an upper pressing roller located above the roller, and a lifting drive member that drives the upper pressing roller to rise and fall. Therefore, when the roller drives the steel wire hose to rotate, the upper pressing roller lightly presses the outer cylindrical surface of the steel wire hose, and the upper pressing roller cooperates with the pipe body guide mechanism to keep the steel wire hose fixed at two points at all times, effectively preventing the steel wire hose from shaking on the roller.

[0025] Furthermore, each set of pipe opening trimming devices also includes an upper pressing block located above the rollers, and a lifting and lowering driving member that drives the upper pressing block to move up and down. Thus, when the steel hose first reaches the rollers, the upper pressing block moves downward to push the steel hose down into the V-shaped groove formed between the two rollers. The upper pressing block can also be installed on a translation driving member, and the upper pressing block can push down the steel hose multiple times by translation.

[0026] Furthermore, the rollers are provided with several rollers for supporting the steel hose; a spacing is formed between every two rollers, and extension plates are provided on both sides of the jacking plate in the spacing. Thus, rollers of corresponding diameters can be replaced according to the diameter of the steel hose. At the same time, installing the extension plate on the top of the jacking plate can not only increase the supporting area of ​​the jacking plate, but also guide the steel hose into the V-shaped plate through the extension plate.

[0027] Furthermore, the pipe mouth trimming machine also includes a loading device and a unloading device, wherein the loading device is located beside one group of the pipe mouth trimming devices, and the unloading device is located beside another group of the pipe mouth trimming devices; the loading device includes a loading bin inclined toward the pipe mouth trimming devices, a baffle fixed in the loading bin, and a loading support plate arranged below the loading bin, wherein the top of the loading support plate is provided with several push plates with inclined support surfaces, and the bottom is provided with a cylinder for driving the lifting thereof; the unloading device includes a unloading bin inclined outward from the pipe mouth trimming devices. Thus, the steel wire hose is arranged in the loading bin, and the loading support plate pushes up the steel wire hose closest to the baffle or located above the loading support plate, and the steel wire hose is guided by the inclined support surface to the adjacent pipe mouth trimming device for automatic loading. After both pipe openings of the steel wire hose are trimmed, the lifting plate close to the unloading mechanism rises upward to lift the steel wire hose off the roller and guide it to the lower granary to realize automatic unloading.

[0028] Furthermore, the feeding device and the transfer device are both provided with a side push plate for pushing the steel hose sideways to position, and a translation driving member for driving the side push plate to translate. Thus, the steel hose to be transferred can be moved to the best transfer position by the side push plate to ensure that the steel hose can be captured by the pipe opening clamping mechanism.

[0029] Furthermore, the sensor is a laser sensor or an optical fiber sensor. Thus, the laser sensor or the optical fiber sensor determines the cutting position of the rubber and the shearing position of the steel wire by detecting the protruding part of the steel wire cut, so as to prevent waste caused by multiple cutting.

[0030] Furthermore, a transverse through slot is provided in one of the guide blocks, and the rubber cutting tool is located in the through slot, and is driven by a cylinder to extend or retract its cutting edge into the through slot. Thus, the position of the rubber cutting tool and the position of the guide block are always kept consistent, and are not affected by the accumulated displacement difference, thereby ensuring the cutting accuracy of the rubber.

[0031] Furthermore, the tube body guiding mechanism includes a cylinder that drives two guiding blocks to rise and fall simultaneously.

[0032] Furthermore, the translation drive component is a linear module.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The present invention adopts two sets of pipe opening trimming devices arranged in parallel and in opposite directions, so that one machine can complete the trimming of the pipe openings at both ends of the steel wire hose, and the two sets of pipe opening trimming devices can work at the same time, thereby improving the efficiency of pipe opening trimming;

[0035] 2. The present invention adopts a transfer device to automatically transfer the steel wire hose to another set of pipe opening trimming devices, which not only saves labor but also improves the transfer efficiency of the steel wire hose;

[0036] 3. The present invention stretches the steel wire hose before cutting the rubber and cutting the steel wire, so that the cutter can accurately contact the hose, thereby improving the cutting accuracy of the pipe opening;

[0037] 4. The present invention uses a sensor to detect the protruding part of the wire cut to determine the cutting position of the rubber and the shearing position of the wire, so as to prevent waste caused by over-cutting;

[0038] 5. The present invention adopts the coordination of a feeding device, a transfer device and a feeding device to realize automatic feeding and feeding of the steel wire hose, realize full automation of the machine, improve the cutting efficiency of the steel wire hose, and save labor costs.

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0046] Embodiment 1

[0047] like Figure 1 The automatic pipe end trimming machine for steel wire hose shown in the figure comprises two sets of pipe end trimming devices A arranged side by side and in opposite directions, and a transfer device B located between the two sets of pipe end trimming devices. The two sets of pipe end trimming devices trim the two pipe ends of the steel wire hose respectively, and the transfer device transfers the steel wire hose from one set of pipe end trimming devices to the other set of pipe end trimming devices.

[0048] like Figure 2 As shown, the pipe mouth trimming device includes two parallel and co-rotating rollers A10, a rubber cutting tool A20, a wire cutting tool A30, a pipe body clamping mechanism A40, a pipe body guiding mechanism A50 and a pipe mouth clamping mechanism A60. The wire cutting tool and the pipe body clamping mechanism are located above the rollers. The pipe body guiding mechanism, the pipe mouth clamping mechanism and the rubber cutting tool are located at the same end of the rollers, and the pipe body guiding mechanism is located between the rollers and the pipe mouth clamping mechanism.

[0049] The wire cutting tool A30 is pneumatic, and the cutting part is a pair of scissors similar to surgical scissors. The tube body clamping mechanism A40 is pneumatic, and the inner sides of the two clamping blocks have grooves that match the outer cylindrical surface of the wire hose. A mounting platform C is arranged above the roller, and a linear module D parallel to the length direction of the roller is arranged on the mounting platform. A double-rod cylinder E is installed on the side slide of the linear module, and the tube body clamping mechanism is fixedly connected to the telescopic rod of the double-rod cylinder. A double-rod cylinder F that drives the wire cutting tool to rise and fall is also arranged on the mounting platform. The cylinder can be fixed on the mounting platform or on the side slide of the linear module.

[0050] The nozzle clamping mechanism A60 is a pneumatic type, which includes two clamping plates that can be gathered inwards and opened outwards. Figure 3 The pipe body guide mechanism A50 is a pneumatic type, which includes two guide blocks A51 that can be gathered inward and opened outward, a cylinder A54 that drives the two guide blocks to rise and fall simultaneously, and a sensor A52 for detecting the position of the pipe mouth. A thread groove A53 is provided on the inner side of the two guide blocks, and the thread of the threaded hole formed by the two guide blocks gathering together matches the pipe body thread of the stretched steel wire hose. The sensor can be a laser sensor or a fiber optic sensor. These two sensors are installed on the side of the pipe body guide mechanism relative to the pipe mouth clamping mechanism, and the rubber cutting position and the steel wire shearing position are judged by detecting the protruding part of the steel wire cut.

[0051] The trimming process of the pipe mouth trimming device is as follows:

[0052] 1. The steel wire hose is placed on the roller, and the pipe mouth clamping mechanism clamps one end of the steel wire hose;

[0053] 2. The tube body clamping mechanism moves downward to clamp the tube body of the steel wire hose and stretch the tube body backward;

[0054] 3. The two guide blocks of the tube body guide mechanism gather inward to clamp the steel wire hose;

[0055] 4. The pipe body clamping mechanism and the pipe mouth clamping mechanism release the steel wire hose, and the roller drives the steel wire hose to rotate. The hose rotates backward under the guidance of the threaded hole of the pipe body guide mechanism;

[0056] 5. When the sensor detects the cutting position of the steel wire, the roller drives the hose to rotate at least one more circle. During this process, the rubber cutting tool extends out to cut the rubber;

[0057] 6. After the wire hose stops rotating, the wire cutting tool moves downward to cut the wire.

[0058] The rubber cutting tool A20 starts working after the sensor detects the cutting position. The cutting edge of the rubber cutting tool should correspond to the threaded hole. The rubber cutting tool can be set above, below or on the side of the threaded hole. Since the movement process of the guide block involves lifting and translation, in order to keep the position of the rubber cutting tool consistent with the position of the guide block and not be affected by the displacement accumulation difference, the cutting accuracy of the rubber is guaranteed. In this embodiment, a horizontal through groove A54 is set in one of the guide blocks, and the rubber cutting tool is placed horizontally in the through groove. When it is necessary to cut the rubber, the cylinder A21 drives the cutting edge to extend out of the through groove.

[0059] The steel hose is placed on the roller, and the tube body guide mechanism can only clamp one end (one point) of the steel hose. During the rotation and retreat of the steel hose, the steel hose is prone to jumping and twisting, so each set of pipe mouth trimming device can also be provided with an upper pressure roller A70 driven by a cylinder to rise and fall. The cylinder can be fixed on the installation platform C or on the side slide of the linear module D. During the rotation of the steel hose driven by the roller, the upper pressure roller A70 lightly presses the outer cylindrical surface of the steel hose. The upper pressure roller A70 cooperates with the tube body guide mechanism A50 to keep the steel hose fixed at two points at all times.

[0060] A V-shaped groove supporting the steel hose will be formed between the two rollers. When the steel hose first reaches the rollers, due to the easy twisting and bending of the steel hose, the steel hose may not enter the V-shaped groove, affecting the stretching process of the steel hose. An upper pressure block A90 driven by a cylinder to lift and lower can be set in each set of pipe mouth trimming device. The cylinder can be fixed on the mounting platform or on the side slide of the linear module. The upper pressure block A90 moves downward to push the steel hose down into the V-shaped groove formed between the two rollers. If the upper pressure block is installed on the linear module, the upper pressure block can push the steel hose down multiple times.

[0061] Continue to see Figure 1 The transfer device includes a V-shaped plate B10, a bracket B20 and a lifting cylinder (not shown in the figure). The bracket is fixed between two sets of pipe mouth trimming devices, and the V-shaped plate is hinged at the top of the bracket. The lifting cylinder serves as a power source to drive the V-shaped plate to rotate and swing to both sides.

[0062] In order to cooperate with the action of the transfer device, a lifting plate A80 should be provided between the two rollers A10 of the pipe mouth trimming device, and a lifting cylinder to drive the lifting plate to be installed under the lifting plate. The supporting surface of the lifting plate is small. When the lifting plate lifts the steel wire hose upward, the steel wire hose is easy to slide off the lifting plate. In this embodiment, several rollers A11 with diameters matching the diameter of the steel wire hose are installed on the rollers. These rollers are preferably arranged equidistantly and fixed to the rollers with bolts. A gap is formed between every two rollers. Extension plates A81 located in the gap are provided on both sides of the lifting plate. Installing an extension plate on the top of the lifting plate can not only increase the supporting area of ​​the lifting plate, but also guide the steel wire hose into the V-shaped plate through the extension plate.

[0063] The transfer process of the steel wire hose in the two sets of pipe mouth trimming devices is as follows:

[0064] 1. After the steel wire of the steel hose is cut, the lifting cylinder drives the V-shaped plate to tilt to one side;

[0065] 2. The lifting plate rises upward to push the steel hose off the roller, and then the steel hose slides into the inclined V-shaped plate;

[0066] 3. The lifting cylinder drives the V-shaped plate to tilt to the other side, and the wire hose slides onto another set of rollers.

[0067] The wire hose passes through the V-shaped plate B10 and comes to another set of rollers. The position of the wire hose may change, and the pipe mouth clamping mechanism A60 may not catch the wire hose. Therefore, after the wire hose comes to the V-shaped plate, the position of the wire hose needs to be adjusted. The transfer device is provided with a side push plate B30 for pushing the wire hose sideways and a cylinder for driving the side push plate to move horizontally. A fixed positioning plate B40 is provided at the end of the V-shaped plate, and the side push plate pushes the wire hose to be transferred in the V-shaped plate to the positioning plate. A sensor can be set at the positioning plate. After the pipe mouth of the wire hose contacts the positioning plate, the sensor sends a signal to the PLC, and the side push plate stops moving horizontally and resets.

[0068] Embodiment 2

[0069] like Figure 4 and 5 As shown, in this embodiment, a loading device G and a unloading device H are added to the pipe mouth trimming machine of embodiment 1. The loading device is located beside one group of pipe mouth trimming devices, and the unloading device is located beside the other group of pipe mouth trimming devices.

[0070] The feeding device comprises a feeding bin which is inclined outward from the pipe mouth trimming device.

[0071] See also Figure 5 The feeding device G includes a feeding bin G10 inclined toward the pipe mouth trimming device, a baffle G20 fixed in the feeding bin, and a feeding support plate G30 arranged below the feeding bin. The top of the feeding support plate is provided with several push plates G40 with inclined support surfaces, and the bottom is provided with a cylinder G50 for driving the lifting thereof. The steel wire hose is arranged in the feeding bin, and the feeding support plate lifts up the steel wire hose closest to the baffle or located above the feeding support plate, and the steel wire hose is guided by the inclined support surface to the adjacent pipe mouth trimming device to realize automatic feeding. After the two pipe mouths of the steel wire hose are trimmed, the lifting plate close to the unloading mechanism rises upward to push the steel wire hose off the roller and guide it to the lower granary to realize automatic unloading.

[0072] The steel hose at the loading station needs to be adjusted to the best loading position so that the steel hose can be caught by the pipe mouth clamping mechanism when it comes to the roller. The loading device is provided with a side push plate G60 for pushing the steel hose sideways and a cylinder for driving the side push plate to move horizontally. A positioning plate is provided at the end of the loading bin, and the side push plate pushes the steel hose sideways to the positioning plate. A sensor can be set at the positioning plate. After the pipe mouth of the steel hose contacts the positioning plate, the sensor sends a signal to the PLC, and the side push plate stops moving horizontally and resets.

[0073] It should be noted that the linear module that drives the translation of the tube body clamping mechanism can also be replaced with a translation drive of other structures, such as: a cylinder, a ball screw pair, etc. The double-rod cylinder that drives the wire cutting tool and the tube body clamping mechanism to rise and fall can be replaced with a lifting drive of other structures, such as: a single-rod cylinder, a ball screw pair, etc. Similarly, the cylinder that is mainly used to control the lifting and translation of a certain component in this embodiment can be replaced with a driving member of other structures according to the overall structure of the tube mouth repair machine, the manufacturing cost, the process requirements of the tube mouth repair, and other factors.

[0074] The above-described embodiment only expresses one implementation method of the present application, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be based on the attached claims.
