Description

Technical Field

[0001] The present invention relates to the field of high-speed rail spring clip fastener raw material processing, and in particular to a high-speed rail spring clip fastener raw material straightening and cutting device. Background Art

[0002] Spring clips are made from rods of various lengths, straightened from coils and then cut using a cutting machine. Although straightened, the internal stresses in these rods are not yet fully released. During spring clip production, the cut rods are heated to approximately 1000°C using an intermediate frequency heating process. This heating further releases the internal stresses, which can cause the rods to bend. When spring clips are produced from these bent rods, the robot gripper may misalign, leading to material leakage and large dimensional deviations in the finished clips. Therefore, the spring clip raw material must be straightened.

[0003] For example, the utility model patent with publication number CN209773317U discloses a CNC straightening and cutting machine, including a machine table, a trapezoidal cover is provided at the middle position of the front side of the upper end of the machine table, strip plates are installed on the upper sides of the left and right end surfaces of the trapezoidal cover, two groups of square plates are symmetrically installed on the lower end surfaces of the strip plates by bolts, a shock-absorbing spring is fixed to the lower end of the shock-absorbing spring, and square plate two is fixed to the machine table by bolts, a square cylinder is provided at the middle position of the front end surface of the machine table, a fixing ear is welded on the right end surface of the square cylinder, and the fixing ear is fixed to the machine table by bolts, a slide groove is fixed at the lower end of the trapezoidal cover, and the lower end of the slide groove extends to the upper side of the square cylinder, and a small vibrator is installed on the front end surface of the trapezoidal cover by bolts.

[0004] The above case has the following defects: since the cut rods are heated to about 1000℃ by medium frequency, an oxidation reaction will occur on the surface of the rods to form a layer of oxide scale. During the straightening process, this layer of oxide scale is easy to peel off and fall on the straightening roller. If the oxide layer accumulates on the roller surface and is not cleaned in time, it is easy to form lumps, causing the surface of the straightening roller to be uneven, thereby easily reducing the straightening accuracy of the rods.

[0005] To this end, the present invention proposes a raw material straightening and cutting device for high-speed rail spring clip fasteners to solve the above problems. Summary of the Invention

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a raw material straightening and cutting device for high-speed rail spring clip fasteners, comprising:

[0007] A processing table, wherein a plurality of first pressing rollers and a second pressing roller are rotatably connected in an array on the sidewall of the processing table, and the second pressing rollers are located directly above the first pressing rollers;

[0008] A rotary drive mechanism, the rotary drive mechanism is used to drive the first pressing roller and the second pressing roller to rotate so as to transport the workpiece to be processed in a horizontal direction;

[0009] Two mounting seats, the two mounting seats are symmetrically slidably connected to the side walls of the processing table, and mounting brackets are symmetrically provided on the left and right sides of the first pressing roller and the second pressing roller, and the mounting brackets are respectively fixedly connected to the mounting seats at corresponding positions;

[0010] Slide blocks are slidably connected in the grooves of the left and right mounting frames of the first and second pressure rollers, and a first spring is fixedly connected between the slide blocks and the mounting frames;

[0011] A rolling column is rotatably connected between the two sliders on the left and right sides of the first and second pressing rollers, and the two rolling columns are in contact with the bottom end surface of the first pressing roller and the top end surface of the second pressing roller respectively;

[0012] The ends of the left and right mounting frames of the first and second pressing rollers are both provided with arc-shaped clearance grooves for allowing the parts to be processed to pass through;

[0013] In a specific implementation process, it also includes a first cylinder, which is fixedly connected to the processing table, and the top end of the telescopic rod of the first cylinder is fixedly connected to the mounting base located above;

[0014] a second cylinder, the second cylinder being fixedly connected to the bottom end of the processing table, and the top end of the telescopic rod of the second cylinder being fixedly connected to the mounting base located below;

[0015] Specifically, in the prior art, since the cut bar is heated to about 1000°C by medium frequency, an oxidation reaction occurs on the surface of the bar, forming a layer of oxide scale. During the straightening process, this oxide scale is easy to peel off and fall onto the straightening roller. If the oxide layer accumulates on the roller surface and is not cleaned in time, it is easy to form lumps, resulting in an uneven surface of the straightening roller, thereby easily reducing the bar straightening accuracy. This technical solution can solve the above problem. The specific operation is as follows:

[0016] The workpiece to be processed is passed between the first and second pressing rollers, and then the rotary drive mechanism is started to rotate the first and second pressing rollers, thereby transporting the workpiece to be processed in a horizontal direction. During the transportation process, the workpiece to be processed is straightened by the pressing action of the first and second pressing rollers, thereby reducing the dimensional error of the forming spring strip;

[0017] After the first and second pressing rollers have been straightened for a long time, the first and second cylinders are started to move the two mounting seats closer to each other, so that the two rolling columns are respectively close to the bottom end of the first pressing roller and the top end of the second pressing roller, and are in contact with the surfaces of the first and second pressing rollers;

[0018] After the rolling column contacts the surfaces of the first and second rollers respectively, the slider slides along the inner groove of the mounting frame under the squeezing effect of the first and second rollers, and the first spring is compressed, thereby ensuring that the rolling column fully contacts the surfaces of the first and second rollers respectively;

[0019] Since the first and second pressing rollers are in a rotating state, the surfaces of the first and second pressing rollers are squeezed against the rolling column, which is conducive to crushing the lumps on the surfaces of the first and second pressing rollers. Subsequently, under the action of gravity, the lumps automatically fall off from the surfaces of the first and second pressing rollers, thereby facilitating the restoration of the flatness of the surfaces of the first and second pressing rollers and reducing the error in bar straightening;

[0020] After the cleaning is completed, the two mounting seats are moved away from each other through the first cylinder and the second cylinder, so that the two rolling columns are respectively away from the bottom end of the first pressure roller and the top end of the second pressure roller, avoiding the problem of the rolling columns being in contact with the surfaces of the first pressure roller and the second pressure roller for a long time, causing wear of the first pressure roller and the second pressure roller.

[0021] Preferably, it also includes:

[0025] Cams are fixedly connected to the shafts of the first pressing roller and the second pressing roller, and the cams are used to push the lining plate so that the first rack plate slides along the side wall of the mounting frame.

[0026] Preferably, the two left side walls of the sliders of the first and second pressure rollers are fixedly connected to a bracket, the bottom end of the bracket is rotatably connected to a brush roller, and the two brush rollers are in contact with the left sides of the first and second pressure rollers respectively.

[0027] Preferably, it also includes:

[0028] a second gear fixedly connected to the shaft of the brush roller;

[0029] a second rack plate, the second rack plate sliding through the mounting frame and meshing with the second gear;

[0030] A driving plate, the driving plate being fixedly connected to the side wall of the second rack plate, and the top of the driving plate being provided with an oblique groove;

[0031] A driving frame, wherein the driving frame is slidably connected to the side wall of the slider, the side wall of the driving plate is provided with a straight groove, the bottom end of the driving frame is fixedly connected to a connecting pin, and the connecting pin is slidably connected in the oblique groove;

[0032] Two connecting plates are fixedly connected to the side walls of the first pressure roller shaft and the second pressure roller shaft. The side walls of the connecting plates are fixedly connected with push pins, and the push pins are slidably connected in the straight grooves.

[0033] Preferably, an air cavity is provided at the end of the rolling column near the brush roller, and a plurality of air holes are provided in an array at the bottom end of the air cavity. A piston is slidably connected in the air cavity, and a connecting frame is fixedly connected to the bottom end of the piston, and the connecting frame is fixedly connected to the second rack plate.

[0034] Preferably, the rotation drive mechanism includes:

[0035] A driving motor, wherein the driving motor is fixedly connected to the side wall of the processing table, and the end of the output shaft of the driving motor is fixedly connected to a driving gear;

[0036] A transmission gear, the transmission gear is fixedly connected to the shaft of one of the first pressure rollers, the transmission gear is meshed with the driving gear, and a first belt is provided for transmission between the shafts of the first pressure rollers;

[0037] A transmission belt is provided between the output shaft surface of the driving motor and one of the second pressure roller shafts, and second belts are provided between several of the second pressure rollers.

[0038] Preferably, a scraper is fixedly connected to the side wall of the slider, the end of the scraper extends toward the rolling column, and the bottom end of the scraper is in contact with the rolling column.

[0039] Preferably, it also includes:

[0040] A plurality of support roller groups are rotatably connected to the side wall of the processing table in an array for supporting the parts to be processed.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. The present invention provides a rolling column, which contacts the surfaces of the first and second rollers respectively, so that the surfaces of the first and second rollers are squeezed by the rolling column, which is conducive to crushing the lumps on the surfaces of the first and second rollers. Then, under the action of gravity, the lumps automatically fall off from the surfaces of the first and second rollers, which is conducive to restoring the flatness of the surfaces of the first and second rollers and reducing the error of bar straightening.

[0043] 2. The present invention sets a first gear and a first rack plate. After the rolling column contacts the surfaces of the first pressure roller and the second pressure roller respectively, the liner is pushed by the cam, so that the liner drives the first rack plate to move along the side wall of the mounting frame, and the second spring is compressed. During the movement of the first rack plate, the first rack plate drives the first gear to rotate. During the continuous rotation of the cam, the first rack plate moves back and forth in the height direction under the elastic action of the second spring, so that the rolling column performs a reciprocating rotational motion to generate axial pressure on the tumor blocks on the surfaces of the first pressure roller and the second pressure roller, which is conducive to making the tumor blocks be crushed more thoroughly, further restoring the flatness of the surfaces of the first pressure roller and the second pressure roller, and reducing the error of bar straightening.

[0044] 3. The present invention sets a brush roller, a second gear and a second rack plate. During the rotation of the rolling column, the connecting plate drives the pushing pin to push the driving frame, so that the driving frame moves along the side wall of the slider, and the connecting pin moves along the inclined groove. Driven by the inclined groove, the driving plate drives the second rack plate to move back and forth in a straight line, thereby driving the second gear to perform reciprocating rotational motion, causing the brush roller to rotate back and forth. The brush roller further cleans the impurities remaining on the surfaces of the first and second pressure rollers, restores the flatness of the surfaces of the first and second pressure rollers, and further reduces the error of bar straightening.

[0045] 4. The present invention sets air holes and pistons. During the reciprocating linear movement of the second rack plate, the piston is connected to the connecting frame so as to make the piston move back and forth linearly along the air cavity, so that the air in the air cavity is compressed and blows air to the surfaces of the brush roller and the first and second pressure rollers through the air holes. On the one hand, impurities remaining on the surfaces of the first and second pressure rollers are further cleaned, the flatness of the surfaces of the first and second pressure rollers is restored, and the error of rod straightening is reduced. On the other hand, impurities in the brush roller are cleaned, and the cleanliness of the surface of the brush roller is improved, thereby improving the cleaning ability of the brush roller on the first and second pressure rollers.

DETAILED DESCRIPTION

[0055] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0056] like Figures 1 to 8 The device for straightening and cutting raw materials for high-speed rail spring clip fasteners shown includes:

[0057] A processing table 1, a plurality of first pressing rollers 2 and second pressing rollers 3 are rotatably connected to the sidewall of the processing table 1, and the second pressing rollers 3 are located directly above the first pressing rollers 2;

[0058] The rotary drive mechanism is used to drive the first pressing roller 2 and the second pressing roller 3 to rotate so as to transport the parts to be processed in a horizontal direction;

[0059] Two mounting seats 5 are symmetrically and slidably connected to the side walls of the processing table 1. Mounting brackets 6 are symmetrically provided on the left and right sides of the first pressing roller 2 and the second pressing roller 3. The mounting brackets 6 are respectively fixedly connected to the mounting seats 5 at corresponding positions;

[0060] Slide blocks 8 are slidably connected in the grooves of the left and right mounting frames 6 of the first and second pressure rollers 2 and 3, and a first spring 9 is fixedly connected between the slide blocks 8 and the mounting frames 6;

[0061] A rolling column 10 is rotatably connected between the two sliders 8 on the left and right sides of the first pressing roller 2 and the second pressing roller 3. The two rolling columns 10 are in contact with the bottom end surface of the first pressing roller 2 and the top end surface of the second pressing roller 3 respectively;

[0062] The ends of the left and right mounting frames 6 of the first pressing roller 2 and the second pressing roller 3 are both provided with arc-shaped clearance grooves 7 for allowing the parts to be processed to pass through;

[0063] Specifically, in the prior art, since the cut bar is heated to about 1000°C by medium frequency, an oxidation reaction occurs on the surface of the bar, forming a layer of oxide scale. During the straightening process, this oxide scale is easy to peel off and fall onto the straightening roller. If the oxide layer accumulates on the roller surface and is not cleaned in time, it is easy to form lumps, resulting in an uneven surface of the straightening roller, thereby easily reducing the bar straightening accuracy. This technical solution can solve the above problem. The specific operation is as follows:

[0064] The workpiece to be processed is passed between the first pressing roller 2 and the second pressing roller 3, and then the rotary drive mechanism is started to rotate the first pressing roller 2 and the second pressing roller 3, thereby transporting the workpiece to be processed in the horizontal direction. During the transportation process, the workpiece to be processed is straightened by the pressing action of the first pressing roller 2 and the second pressing roller 3, thereby reducing the dimensional error of the forming spring strip;

[0065] After the first and second rollers 2 and 3 have been straightened for a long time, the first and second cylinders 101 and 102 are activated to move the two mounting seats 5 closer to each other, and the two rolling columns 10 are respectively closer to the bottom end of the first roller 2 and the top end of the second roller 3, and in contact with the surfaces of the first and second rollers 2 and 3;

[0066] After the rolling column 10 contacts the surfaces of the first pressing roller 2 and the second pressing roller 3 respectively, it is squeezed by the first pressing roller 2 and the second pressing roller 3, causing the slider 8 to slide along the inner groove of the mounting frame 6, and the first spring 9 is compressed, thereby ensuring that the rolling column 10 is fully in contact with the surfaces of the first pressing roller 2 and the second pressing roller 3 respectively;

[0067] Since the first pressing roller 2 and the second pressing roller 3 are in a rotating state, the surfaces of the first pressing roller 2 and the second pressing roller 3 are squeezed with the rolling column 10, which is conducive to crushing the lumps on the surfaces of the first pressing roller 2 and the second pressing roller 3. Then, under the action of gravity, the lumps automatically fall off from the surfaces of the first pressing roller 2 and the second pressing roller 3, which is conducive to restoring the flatness of the surfaces of the first pressing roller 2 and the second pressing roller 3 and reducing the error of bar straightening;

[0068] After the cleaning is completed, the two mounting seats 5 are moved away from each other by the first cylinder 101 and the second cylinder 102, so that the two rolling columns 10 are respectively away from the bottom end of the first pressure roller 2 and the top end of the second pressure roller 3, to avoid the problem of the rolling columns 10 being in contact with the surfaces of the first pressure roller 2 and the second pressure roller 3 for a long time, causing wear of the first pressure roller 2 and the second pressure roller 3.

[0069] As an optional embodiment of the rotary drive mechanism, the rotary drive mechanism includes:

[0070] A driving motor 31 is fixedly connected to the side wall of the processing table 1, and a driving gear 32 is fixedly connected to the end of the output shaft of the driving motor 31;

[0071] A transmission gear 33 is fixedly connected to the shaft of one of the first pressure rollers 2. The transmission gear 33 is meshed with the driving gear 32. A first belt 34 is provided for transmission between the shafts of the first pressure rollers 2.

[0072] A transmission belt 35 is provided between the output shaft surface of the driving motor 31 and the shaft of one of the second pressing rollers 3 , and a second belt 36 is provided between the plurality of second pressing rollers 3 ;

[0073] Specifically, by starting the driving motor 31, the output shaft of the driving motor 31 rotates, the driving gear 32 rotates, the transmission gear 33 rotates, the first pressing roller 2 rotates, and the belt transmission causes the first pressing rollers 2 to rotate synchronously.

[0074] And during the rotation of the output shaft of the driving motor 31, the second pressing roller 3 is rotated through the transmission belt 35, and the second pressing rollers 3 at other positions are rotated synchronously through the transmission of the second belt 36, thereby driving the rotation of the first pressing roller 2 and the second pressing roller 3 to transport the parts to be processed horizontally and straighten them.

[0075] It should be noted that the transmission gear 33 and the driving gear 32 have the same radius, thereby ensuring that the first pressing roller 2 and the second pressing roller 3 rotate at the same speed.

[0077] The first gear 15 is fixedly connected to the shaft of the rolling column 10;

[0079] A lining plate 18 , the lining plate 18 is fixedly connected to the side wall of the first rack plate 16 ;

[0080] The shafts of the first pressing roller 2 and the second pressing roller 3 are both fixedly connected with a cam 19, which is used to push the lining plate 18 so that the first rack plate 16 slides along the side wall of the mounting frame 6;

[0081] Specifically, by setting the first gear 15 and the first rack plate 16, after the rolling column 10 contacts the surfaces of the first pressure roller 2 and the second pressure roller 3 respectively, the liner 18 is pushed by the cam 19, so that the liner 18 drives the first rack plate 16 to move along the side wall of the mounting frame 6, and the second spring 17 is compressed. During the movement of the first rack plate 16, the first rack plate 16 drives the first gear 15 to rotate. During the continuous rotation of the cam 19, under the elastic action of the second spring 17, the first rack plate 16 moves back and forth in the height direction, so that the rolling column 10 performs a reciprocating rotational motion to generate axial pressure on the tumor blocks on the surfaces of the first pressure roller 2 and the second pressure roller 3, which is conducive to making the tumor blocks be crushed more thoroughly, further restoring the flatness of the surfaces of the first pressure roller 2 and the second pressure roller 3, and reducing the error of bar straightening.

[0082] As a further embodiment of the present invention, the side walls of the two sliders 8 on the left side of the first pressing roller 2 and the second pressing roller 3 are fixedly connected to a bracket 20, and the bottom end of the bracket 20 is rotatably connected to a brush roller 21, and the two brush rollers 21 are in contact with the left side surfaces of the first pressing roller 2 and the second pressing roller 3 respectively;

[0089] Specifically, by setting the brush roller 21, the second gear 22 and the second rack plate 23, during the rotation of the rolling column 10, the connecting plate 29 drives the pushing pin 30 to push the driving frame 26, so that the driving frame 26 moves along the side wall of the slider 8, and the connecting pin 28 moves along the inclined groove 25. Under the drive of the inclined groove 25, the driving plate 24 drives the second rack plate 23 to move back and forth in a straight line, thereby driving the second gear 22 to perform reciprocating rotational motion, so that the brush roller 21 rotates back and forth, and the brush roller 21 further cleans the impurities remaining on the surface of the first pressure roller 2 and the second pressure roller 3, restores the flatness of the surface of the first pressure roller 2 and the second pressure roller 3, and further reduces the error of bar straightening.

[0090] As a further embodiment of the present invention, an air cavity 11 is formed at the end of the rolling column 10 near the brush roller 21, and a plurality of air holes 12 are formed in an array at the bottom end of the air cavity 11. A piston 13 is slidably connected to the air cavity 11, and a connecting frame 14 is fixedly connected to the bottom end of the piston 13. The connecting frame 14 is fixedly connected to the second rack plate 23;

[0091] Specifically, by setting the air hole 12 and the piston 13, during the reciprocating linear movement of the second rack plate 23, the piston 13 is connected to the connecting frame 14, so that the air in the air cavity 11 is compressed, and air is blown to the surface of the brush roller 21 and the first pressing roller 2 and the second pressing roller 3 through the air hole 12. On the one hand, the impurities remaining on the surface of the first pressing roller 2 and the second pressing roller 3 are further cleaned, the flatness of the surface of the first pressing roller 2 and the second pressing roller 3 is restored, and the error of the rod straightening is reduced. On the other hand, the impurities in the brush roller 21 are cleaned, and the cleanliness of the surface of the brush roller 21 is improved, thereby improving the cleaning ability of the brush roller 21 to the first pressing roller 2 and the second pressing roller 3.

[0094] As a further embodiment of the present invention, it also includes:

[0095] Several support roller groups 4 are rotatably connected to the side wall of the processing table 1 in an array to support the parts to be processed.

[0096] The working principle of the present invention is as follows:

[0097] The workpiece to be processed is passed between the first pressing roller 2 and the second pressing roller 3, and then the rotary drive mechanism is started to rotate the first pressing roller 2 and the second pressing roller 3, thereby transporting the workpiece to be processed in the horizontal direction. During the transportation process, the workpiece to be processed is straightened by the pressing action of the first pressing roller 2 and the second pressing roller 3, thereby reducing the dimensional error of the forming spring strip;

[0098] After the first and second rollers 2 and 3 have been straightened for a long time, the first and second cylinders 101 and 102 are activated to move the two mounting seats 5 closer to each other, and the two rolling columns 10 are respectively closer to the bottom end of the first roller 2 and the top end of the second roller 3, and in contact with the surfaces of the first and second rollers 2 and 3;

[0099] After the rolling column 10 contacts the surfaces of the first pressing roller 2 and the second pressing roller 3 respectively, it is squeezed by the first pressing roller 2 and the second pressing roller 3, causing the slider 8 to slide along the inner groove of the mounting frame 6, and the first spring 9 is compressed, thereby ensuring that the rolling column 10 is fully in contact with the surfaces of the first pressing roller 2 and the second pressing roller 3 respectively;

[0100] Since the first pressing roller 2 and the second pressing roller 3 are in a rotating state, the surfaces of the first pressing roller 2 and the second pressing roller 3 are squeezed with the rolling column 10, which is conducive to crushing the lumps on the surfaces of the first pressing roller 2 and the second pressing roller 3. Then, under the action of gravity, the lumps automatically fall off from the surfaces of the first pressing roller 2 and the second pressing roller 3, which is conducive to restoring the flatness of the surfaces of the first pressing roller 2 and the second pressing roller 3 and reducing the error of bar straightening;

[0101] After the cleaning is completed, the two mounting seats 5 are moved away from each other by the first cylinder 101 and the second cylinder 102, so that the two rolling columns 10 are respectively away from the bottom end of the first pressure roller 2 and the top end of the second pressure roller 3, to avoid the problem of the rolling columns 10 being in contact with the surfaces of the first pressure roller 2 and the second pressure roller 3 for a long time, causing wear of the first pressure roller 2 and the second pressure roller 3.

[0102] The basic principles, main features, and advantages of the present invention are shown and described above.

The above embodiments and descriptions only describe the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the invention as claimed.
