Description

Technical Field

[0001] This utility model relates to an interval pushing device for rolling conveying of steel pipes in a thickening process. Background Technology

[0002] In the steel pipe thickening process, the steel pipe needs to undergo heating and thickening operations at both ends sequentially. After one end of the steel pipe is thickened, it needs to enter the intermediate waiting platform, where it rolls and huddles together under its own weight, awaiting the thickening operation at the other end. However, for small-diameter steel pipes (such as φ33.4×3.38, φ42.16×3.56, φ48.26×3.68, etc.), the tangential force generated by its own weight is relatively small. In addition, after thickening, a burr of about 2~5mm in height will form on both sides of the steel pipe, and the outer diameter of the thickened end will increase. These factors combined cause the steel pipe to be unable to roll down automatically, resulting in a stagnation phenomenon.

[0003] The traditional solution was for manual intervention to move the steel pipes within the production line. However, modern fully automated production lines immediately stop once personnel are detected entering the fenced area. If a steel pipe is being heated or thickened in an induction furnace at this time, it will result in scrap pipes, incurring rework costs of cutting, reheating, and thickening. Frequent occurrences of this problem will lead to economic losses and decreased production efficiency.

[0004] A search of existing technologies revealed that Chinese Patent CN210649755U discloses a jacking device for axially pushing steel pipes. This device avoids adjacent steel pipes by machining a flat surface on the side of the jacking rod, thus enabling the pushing of a single steel pipe. However, this device primarily addresses the problem of pushing a single pipe in a densely packed arrangement of steel pipes; it cannot achieve intermittent pushing of steel pipes and is unsuitable for solving the rolling obstruction problem caused by flash interference during the thickening process. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an interval pushing steel device for rolling conveying of steel pipes in the thickening process. It can realize the interval pushing and misalignment of steel pipes, avoid mutual interference of flash, and make the steel pipes roll smoothly by their own weight.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is an intermittent steel pushing device for rolling conveying of steel pipes in thickening processes, comprising:

[0007] frame;

[0008] A tube-pushing mechanism, which is mounted on a frame and is equipped with a longitudinal moving platform;

[0009] A transverse movement mechanism is mounted on the longitudinal movement platform of the push tube mechanism;

[0010] A push rod spacing adjustment mechanism is mounted on the transverse mechanism. The push rod spacing adjustment mechanism is provided with two push rods and is adapted to adjust the spacing between the two push rods.

[0011] The tube pushing mechanism is adapted to drive the push rod of the push rod spacing adjustment mechanism to move along the axial direction of the steel pipe to push the steel pipe, and the lateral movement mechanism is adapted to drive the push rod spacing adjustment mechanism to move in a lateral direction perpendicular to the axial direction of the steel pipe.

[0012] Furthermore, a specific structure for a tube-pushing mechanism is provided, the tube-pushing mechanism comprising:

[0013] A drive source, which is mounted on the rack;

[0014] A longitudinal moving mechanism is connected to the drive source, and a longitudinal moving platform is disposed on the longitudinal moving mechanism. The drive source is adapted to drive the longitudinal moving platform to reciprocate along the axial direction of the steel pipe.

[0015] Furthermore, a specific structure of a longitudinal moving mechanism is provided, the longitudinal moving mechanism comprising:

[0016] A longitudinal guide rail is mounted on the frame and extends along the axial direction of the steel pipe;

[0017] A longitudinal slider is slidably engaged with a longitudinal guide rail. The longitudinal moving platform is fixed on the longitudinal slider, and the output end of the drive source is connected to the longitudinal slider.

[0018] Furthermore, a specific type of drive source is provided, wherein the drive source is a cylinder.

[0019] Furthermore, a specific structure for a push rod spacing adjustment mechanism is provided, the push rod spacing adjustment mechanism comprising:

[0020] A transverse support, which is fixed to the transverse movement mechanism;

[0021] An adjustment drive component is mounted on the first side of the transverse support;

[0022] A transmission gear is rotatably mounted on a second side of the transverse support, the second side being opposite to the first side.

[0023] The first guide rod group and the second guide rod group are both installed on the second side of the transverse support, and the first guide rod group and the second guide rod group are respectively located on both sides of the transmission gear;

[0024] A first guide block group and a second guide block group, wherein the first guide block group is slidably mounted on the first guide rod group, and the second guide block group is slidably mounted on the second guide rod group;

[0025] A first rack and a second rack, the first rack being fixed to the first guide block assembly, the second rack being fixed to the second guide block assembly, the first rack and the second rack being located on opposite sides of the transmission gear and meshing with the transmission gear;

[0026] The output end of the adjustment drive unit passes through the transverse bracket and is connected to the first guide block group. The push rods are fixed on the first guide block group and the second guide block group respectively. When the adjustment drive unit drives the first guide block group to move, the first rack drives the second rack to move in the opposite direction synchronously through the transmission gear, thereby adjusting the distance between the two push rods.

[0027] Furthermore, in order to better press the first rack and the second rack, the interval pushing steel device for rolling conveying the steel pipe in the thickening process also includes a pair of pressing wheels. The pair of pressing wheels are respectively disposed on one side of the first rack and the second rack relative to the transmission gear, and the pair of pressing wheels abut against the first rack and the second rack respectively.

[0028] Furthermore, the specific type of adjustment drive is provided, which is a cylinder or an electric push rod.

[0029] Furthermore, a specific structure for a lateral movement mechanism is provided, the lateral movement mechanism comprising:

[0030] A lateral drive unit, which is mounted on the longitudinal moving platform;

[0031] A transverse guide rail is mounted on the longitudinal moving platform and extends in a transverse direction perpendicular to the axial direction of the steel pipe.

[0032] A horizontal slider, which slides in conjunction with the horizontal guide rail;

[0033] A push rod mounting base is fixed on the transverse slider, and a push rod spacing adjustment mechanism is fixed on the push rod mounting base.

[0034] Furthermore, the lateral drive component is a lead screw transmission mechanism driven by a stepper motor or a linear motor.

[0035] By adopting the above technical solution, this utility model has the following beneficial effects:

[0036] In this invention, a tube-pushing mechanism is mounted on a frame, and its longitudinal moving platform can reciprocate along the axial direction of the steel pipe. A transverse moving mechanism is mounted on the longitudinal moving platform, and a push rod spacing adjustment mechanism is mounted on the transverse moving mechanism and has two push rods. When the thickened steel pipe cannot roll on the waiting platform due to interference from the flash, the push rod spacing adjustment mechanism adjusts the spacing between the two push rods according to the specifications of the steel pipe to be pushed, so that the two push rods correspond to the end positions of the two spaced steel pipes respectively. The transverse moving mechanism drives the push rod spacing adjustment mechanism to move in a transverse direction perpendicular to the axial direction of the steel pipe to the ends of the two spaced steel pipes. The tube-pushing mechanism drives the push rods of the push rod spacing adjustment mechanism to move along the axial direction of the steel pipe to simultaneously push the two spaced steel pipes. Because there is a gap between the two push rods, the two pushed steel pipes move forward the same distance, while the steel pipe between the two is not pushed and remains in its original position, thereby achieving axial misalignment between the spaced steel pipes. After the steel pipes are axially misaligned, the flash of adjacent steel pipes no longer overlaps laterally, avoiding interference between the flashes and allowing the steel pipes to roll down the waiting platform under their own weight. This device achieves adjustable pusher spacing through a pusher spacing adjustment mechanism, adapting to the interval pushing requirements of steel pipes of different specifications. It solves the problems of existing steel pushing devices being unable to achieve interval pushing of steel pipes and unable to avoid flash interference, thus realizing the interval pushing and misalignment of thickened steel pipes.

[0037] In summary, this utility model, through the combined configuration of a pusher mechanism, a transverse movement mechanism, and a pusher spacing adjustment mechanism, achieves the functions of adjustable pusher spacing, accurate transverse positioning, and longitudinal pushing separation. It is suitable for the interval pushing operation of steel pipes of different specifications in the thickening process. By pushing at intervals, the axial misalignment of the interval steel pipes is achieved, avoiding mutual interference between the flash of adjacent steel pipes. This allows the steel pipes to roll down on the waiting platform by their own weight, solving the technical problem that the thickened steel pipes cannot roll due to flash interference.

[0042] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0043] like Figure 1-4 As shown, an intermittent steel pushing device for rolling conveying of steel pipes in a thickening process includes:

[0044] Rack 1;

[0045] The tube pushing mechanism 2 is mounted on the frame 1 and is equipped with a longitudinal moving platform.

[0046] The transverse movement mechanism 3 is installed on the longitudinal movement platform of the tube pushing mechanism 2;

[0047] The push rod spacing adjustment mechanism 4 is installed on the transverse mechanism 3. The push rod spacing adjustment mechanism 4 is provided with two push rods 48. The push rod spacing adjustment mechanism 4 is suitable for adjusting the spacing between the two push rods 48.

[0048] Among them, the pusher mechanism 2 is adapted to drive the pusher 48 of the pusher spacing adjustment mechanism 4 to move along the axial direction of the steel pipe to push the steel pipe, and the transverse mechanism 3 is adapted to drive the pusher spacing adjustment mechanism 4 to move in the transverse direction perpendicular to the axial direction of the steel pipe.

[0049] In this embodiment, as Figure 1 , Figure 3 and Figure 4As shown, the tube pushing mechanism 2 is mounted on the frame 1, and its longitudinal moving platform can reciprocate along the axial direction of the steel pipe. The transverse moving mechanism 3 is mounted on the longitudinal moving platform, and the push rod spacing adjustment mechanism 4 is mounted on the transverse moving mechanism 3 and has two push rods 48. When the thickened steel pipe cannot roll on the waiting platform due to flash interference, the push rod spacing adjustment mechanism 4 adjusts the spacing between the two push rods 48 according to the specifications of the steel pipe to be pushed, so that the two push rods 48 correspond to the end positions of the two spaced steel pipes respectively. The transverse moving mechanism 3 drives the push rod spacing adjustment mechanism 4 to move in the transverse direction perpendicular to the axial direction of the steel pipe to the ends of the two spaced steel pipes. The tube pushing mechanism 2 drives the push rods 48 of the push rod spacing adjustment mechanism 4 to move along the axial direction of the steel pipe to simultaneously push the two spaced steel pipes. Because there is a gap between the two push rods 48, the two pushed steel pipes move forward the same distance, while the steel pipe between the two steel pipes is not pushed and remains in its original position, thereby achieving axial misalignment between the spaced steel pipes. After the steel pipes are axially misaligned, the flash of adjacent steel pipes no longer overlaps laterally, avoiding interference between the flashes and allowing the steel pipes to roll down on the waiting platform under their own weight. This device achieves adjustable spacing between push rods 48 via a push rod spacing adjustment mechanism 4, adapting to the interval pushing requirements of steel pipes of different specifications. It solves the problem in existing steel pushing devices that cannot achieve interval pushing of steel pipes and cannot avoid flash interference, thus realizing the interval pushing and misalignment of thickened steel pipes.

[0050] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the tube pushing mechanism 2 includes:

[0051] Drive source 21, drive source 21 is mounted on rack 1;

[0052] The longitudinal moving mechanism is connected to the drive source 21. The longitudinal moving platform is mounted on the longitudinal moving mechanism. The drive source 21 is adapted to drive the longitudinal moving platform to reciprocate along the axial direction of the steel pipe.

[0053] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the longitudinal moving mechanism includes:

[0054] Longitudinal guide rail 22 is mounted on frame 1 and extends along the axial direction of steel pipe;

[0055] The longitudinal slider 23 is slidably engaged with the longitudinal guide rail 22. The longitudinal moving platform is fixed on the longitudinal slider 23, and the output end of the drive source 21 is connected to the longitudinal slider 23.

[0056] Specifically, such as Figure 2 As shown, the drive source 21 is a cylinder.

[0057] In this embodiment, as Figure 1-2 As shown, the pushing mechanism 2 drives the longitudinal moving mechanism via the drive source 21 to achieve the reciprocating motion of the longitudinal moving platform. In this embodiment, the drive source 21 is a cylinder, with its piston rod connected to the longitudinal slider 23. The cylinder is supplied with air to control the extension and retraction of the piston rod, thereby driving the longitudinal slider 23 to slide along the longitudinal guide rail 22. The longitudinal moving platform is fixed to the longitudinal slider 23 and moves together with it, realizing the reciprocating pushing action along the axial direction of the steel pipe. In other embodiments, the drive source 21 can also be a hydraulic cylinder or an electric push rod.

[0058] The longitudinal guide rail 22 is mounted on the frame 1 and extends along the axial direction of the steel pipe, providing guidance and support for the longitudinal slider 23. The longitudinal slider 23 slides in conjunction with the longitudinal guide rail 22. The longitudinal slider 23 has a sliding groove inside that mates with the longitudinal guide rail 22. The cross-sectional shape of the sliding groove matches the cross-sectional shape of the longitudinal guide rail 22, allowing the longitudinal slider 23 to perform linear reciprocating motion along the longitudinal guide rail 22. The longitudinal moving platform is fixed to the top of the longitudinal slider 23 and is fixedly connected by bolts.

[0059] Specifically, such as Figure 1 and Figure 3 As shown, the push rod spacing adjustment mechanism 4 includes:

[0060] The transverse support 41 is fixed on the transverse movement mechanism 3.

[0061] Adjustment drive 42 is installed on the first side of the transverse bracket 41;

[0062] Transmission gear 43 is rotatably mounted on the second side of the transverse bracket 41, and the second side is opposite to the first side.

[0063] The first guide rod group and the second guide rod group are both installed on the second side of the transverse bracket 41, and the first guide rod group and the second guide rod group are located on both sides of the transmission gear 43 respectively;

[0064] A first guide block group 44 and a second guide block group 45 are slidably mounted on a first guide rod group, and the second guide block group 45 is slidably mounted on a second guide rod group.

[0065] The first rack 46 and the second rack 47 are fixed on the first guide block group 44 and the second rack 47 is fixed on the second guide block group 45. The first rack 46 and the second rack 47 are located on both sides of the transmission gear 43 and mesh with the transmission gear 43.

[0066] The output end of the adjusting drive 42 passes through the transverse bracket 41 and is connected to the first guide block group 44. The push rods 48 are fixed on the first guide block group 44 and the second guide block group 45 respectively. When the adjusting drive 42 drives the first guide block group 44 to move, the first rack 46 drives the second rack 47 to move in the opposite direction synchronously through the transmission gear 43, thereby adjusting the distance between the two push rods 48.

[0067] Specifically, such as Figure 3 As shown, the interval pushing device for rolling conveying steel pipes in the thickening process also includes a pair of pressing wheels. The pair of pressing wheels are respectively disposed on one side of the first rack 46 and the second rack 47 relative to the transmission gear 43, and the pair of pressing wheels abut against the first rack 46 and the second rack 47 respectively.

[0068] Specifically, such as Figure 3 As shown, the adjusting drive component 42 is a cylinder.

[0069] In this embodiment, as Figure 1 and Figure 3 As shown, the push rod spacing adjustment mechanism 4 drives the first guide block group 44 and the second guide block group 45 to move synchronously in opposite directions along the first guide rod group and the second guide rod group through the adjustment drive member 42, thereby adjusting the spacing between the two push rods 48. In this embodiment, the adjustment drive member 42 is a cylinder, which is mounted on the first side of the transverse support 41. The piston rod of the cylinder passes through the transverse support 41 and is connected to the first guide block group 44. A through hole is provided on the first side of the transverse support 41, through which the piston rod of the cylinder extends to the second side of the transverse support 41. The end of the piston rod is fixed to the first guide block group 44 by a threaded connection or a pin connection. When the cylinder drives the piston rod to extend or retract, the first guide block assembly 44 moves along the first guide rod assembly, and the first rack 46 fixed on the first guide block assembly 44 moves accordingly. The first rack 46 meshes with the transmission gear 43, and the transmission gear 43 rotates, driving the second rack 47 to move in the opposite direction. The second rack 47 is fixed on the second guide block assembly 45, thereby causing the second guide block assembly 45 to move synchronously along the second guide rod assembly in the opposite direction to the first guide block assembly 44. Push rods 48 are respectively fixed on the first guide block assembly 44 and the second guide block assembly 45. The two push rods 48 move closer or further apart as the first guide block assembly 44 and the second guide block assembly 45 move in the opposite direction, realizing the adjustment of the distance between the push rods 48. In other embodiments, the adjusting drive 42 can also be an electric push rod or a hydraulic cylinder.

[0070] The transmission gear 43 is rotatably mounted on the second side of the transverse support 41, opposite to the first side. The transmission gear 43 is mounted on the second side of the transverse support 41 via a bearing seat.

The first guide rod group includes two parallel guide rods, and the second guide rod group includes two parallel guide rods, with both ends of the guide rods fixed to the second side of the transverse support 41. The first guide block group 44 is slidably mounted on the first guide rod group. The first guide block group 44 has a sliding hole inside that mates with the guide rod, allowing the guide rod to pass through the sliding hole and slide linearly along the guide rod of the first guide rod group. The second guide block group 45 is slidably mounted on the second guide rod group. The second guide block group 45 has a sliding hole inside that mates with the guide rod, allowing the guide rod to pass through the sliding hole and slide linearly along the guide rod of the second guide rod group. The first rack 46 is fixed on the side of the first guide block assembly 44, and the second rack 47 is fixed on the side of the second guide block assembly 45. The first rack 46 and the second rack 47 are located on both sides of the transmission gear 43 and mesh with the transmission gear 43. The tooth surfaces of the first rack 46 and the second rack 47 face the transmission gear 43, and the teeth of the transmission gear 43 mesh with the teeth of the first rack 46 and the second rack 47 simultaneously.

[0071] The interval pushing device for rolling conveying steel pipes in the thickening process also includes a pair of clamping wheels. The pair of clamping wheels are rotatably mounted on the second side of the transverse support 41. The pair of clamping wheels are respectively located on the side of the first rack 46 and the second rack 47 opposite to the transmission gear 43. The rim of one clamping wheel abuts against the back of the first rack 46, and the rim of the other clamping wheel abuts against the back of the second rack 47. The clamping wheels apply a clamping force to the first rack 46 and the second rack 47 in the direction of the transmission gear 43, so that the first rack 46 and the second rack 47 maintain a stable meshing state with the transmission gear 43 during movement.

[0072] Specifically, such as Figure 1-2 As shown, the transverse movement mechanism 3 includes:

[0073] A transverse drive unit 31 is mounted on a longitudinal moving platform;

[0074] A transverse guide rail 32 is mounted on a longitudinal moving platform and extends in a transverse direction perpendicular to the axial direction of the steel pipe.

[0075] The horizontal slider 33 is in sliding engagement with the horizontal guide rail 32.

[0076] A push rod mounting base 34 is fixed on a transverse slider 33. A push rod spacing adjustment mechanism 4 is fixed on a push rod mounting base 34. The output end of a transverse drive component 31 is connected to a transverse slider 33, which is suitable for driving the push rod spacing adjustment mechanism 4 to move intermittently in the transverse direction.

[0077] Specifically, such as Figure 2 As shown, the lateral drive component 31 is a lead screw transmission mechanism driven by a stepper motor.

[0078] In this embodiment, as Figure 1-2 As shown,

[0079] The lateral movement mechanism 3 drives the lateral slider 33 to move along the lateral guide rail 32 via the lateral drive component 31, thereby achieving the lateral positioning of the push rod spacing adjustment mechanism 4. In this embodiment, the lateral drive component 31 is a lead screw transmission mechanism driven by a stepper motor. The stepper motor is mounted on the longitudinal movement platform, and the output shaft of the stepper motor is connected to one end of the lead screw via a coupling. The lead screw is arranged along the extension direction of the lateral guide rail 32, and the other end of the lead screw is supported on the longitudinal movement platform by a bearing seat. A nut is provided on the lead screw, and the nut is fixedly connected to the lateral slider 33. When the stepper motor drives the lead screw to rotate, the nut moves along the axial direction of the lead screw, causing the lateral slider 33 to slide along the lateral guide rail 32. The stepper motor is controlled by a motor drive circuit. A pulse signal is sent to the stepper motor according to the lateral position of the steel pipe, and the stepper motor rotates by a corresponding angle according to the pulse signal, thereby achieving the position adjustment of the lateral slider 33. In other embodiments, the lateral drive component 31 can also be a linear motor.

[0080] A transverse guide rail 32 is mounted on a longitudinal moving platform and extends in a transverse direction perpendicular to the axial direction of the steel pipe, providing guidance and support for the transverse slider 33. The transverse slider 33 slides along the transverse guide rail 32, and its interior has a sliding groove that matches the cross-sectional shape of the transverse guide rail 32, allowing the transverse slider 33 to reciprocate linearly along the transverse guide rail 32. A push rod mounting base 34 is fixed to the top of the transverse slider 33 via bolts or welding. The transverse support 41 of the push rod spacing adjustment mechanism 4 is fixed to the push rod mounting base 34, and the transverse support 41 is connected to the push rod mounting base 34 via bolts. When the transverse drive component 31 drives the transverse slider 33 to move, the push rod mounting base 34 moves along with the transverse slider 33, causing the push rod spacing adjustment mechanism 4 to move in the transverse direction, allowing the push rod 48 to correspond to the steel pipe ends at different transverse positions.
