Description

Technical Field

[0001] This utility model relates to the technical field of composite pipe processing equipment, specifically to an integrated forming device for multi-reinforced steel-plastic composite pipe strips. Background Technology

[0002] Steel-plastic composite pipes have become an important pipeline material due to their excellent performance and wide range of applications. When producing steel-plastic composite pipes, it is necessary to position the strip or steel mesh used as the support pipe body into the mold, and then introduce the hot-melt polyethylene into the mold for integral molding, thereby improving the processing efficiency of composite pipes.

[0003] However, the existing clamps used to limit the steel mesh during the one-piece molding process of composite pipes are not convenient for limiting steel meshes of different diameters. At the same time, the automation level of composite pipe production is also insufficient. Therefore, there is an urgent need for a one-piece molding device for multi-reinforced steel-plastic composite pipe strips to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide an integrated molding device for multi-reinforced steel-plastic composite pipes and strips to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated forming device for multi-reinforced steel-plastic composite pipe and strip, comprising a positioning bracket for support, a servo motor fixedly disposed at the center of the front end face of the positioning bracket, and a transmission screw fixedly disposed at the output end of the servo motor.

[0006] A fixed bracket is fixedly disposed on the upper part of the rear end face of the positioning bracket, and a molding die is fixedly disposed at the center of the front end face of the fixed bracket.

[0007] The hot melt extrusion tube is provided in eight sets, and the eight sets of hot melt extrusion tubes are fixedly installed on the rear end face of the fixed card seat. The hot melt extrusion tubes are connected to the molding die through the tube.

[0008] A limiting device is provided, which is threadedly connected to the inner end face of the positioning bracket via the transmission screw, and a supporting steel mesh is fixedly engaged on the inner end face of the limiting device.

[0009] Preferably, the limiting device includes a ball bearing slide, a sealing mold seat is fixedly disposed at the center of the front end face of the ball bearing slide, and four sets of limiting slots are equidistantly provided on the inner end face of the sealing mold seat. A stepper motor is fixedly disposed at the center of the rear end face of the ball bearing slide, and a driving bevel gear is fixedly disposed at the output end of the stepper motor. Four sets of driven bevel gears are equidistantly rotated and engaged on the inner end face of the ball bearing slide around the driving bevel gear. A guide screw is fixedly disposed on the inner end face of the driven bevel gear. Four sets of sealing seats are equidistantly threadedly connected to the inner end face of the sealing mold seat through the guide screw. A threaded guide seat is fixedly disposed at the center of the lower end face of the sealing seat. A one-way vent is provided on the rear end face of the ball bearing slide opposite the sealing mold seat.

[0010] Preferably, the sealing bracket is adapted to the threaded guide seat via the guide screw and is thus threadedly slidably connected to the inner end face of the ball slide. The threaded connection between the threaded guide seat and the guide screw can provide sufficient power for guiding the sealing bracket, facilitating subsequent quick and convenient limiting operations on the supporting steel mesh.

[0011] Preferably, the sealing bracket is slidably engaged with the inner wall of the sealing mold base through the limiting slot. The limiting slot can provide sufficient guiding foundation for the sealing bracket, thereby improving the stability of the sealing bracket in limiting the support steel mesh.

[0012] Preferably, the active bevel gear meshes with four sets of driven bevel gears, and the supporting steel mesh is fixedly clamped to the inner end face of the sealing mold seat by the sliding limit of the four sets of sealing seats. The active bevel gear can synchronously drive the four sets of guide screws to rotate through the four sets of driven bevel gears, which can improve the transmission efficiency of the equipment and improve the adaptability to subsequent limiting of different supporting steel meshes.

[0013] Preferably, the ball bearing slide is threadedly slidably connected to the inner end face of the positioning card via the transmission screw. The supporting steel mesh is coaxial with the molding mold, and the supporting steel mesh does not contact the inner or outer wall of the molding mold. This prevents the supporting steel mesh from being exposed after the composite pipe is molded, thus affecting the stability of the composite pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. When shaping support steel meshes of different diameters, the stepper motor can synchronously drive four sets of guide screws to rotate through the active and driven bevel gears. This allows the four sets of guide screws to be connected to the threaded guide seat, thereby driving the sealing seat to centrifugally limit the inside of the limiting slot. This facilitates the subsequent limiting of support steel meshes of different diameters by the sealing seat, and further facilitates the adaptive processing of composite pipes of different diameters, thus improving the practical performance of the equipment.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The present invention provides an embodiment of an integrated forming device for multi-reinforced steel-plastic composite pipe strip, comprising a positioning bracket 6 for support, a servo motor 5 fixedly disposed at the center of the front end face of the positioning bracket 6, and a transmission screw 4 fixedly disposed at the output end of the servo motor 5.

[0023] Fixed bracket 1 is fixedly installed on the upper part of the rear end face of positioning bracket 6, and a molding mold 7 is fixedly installed at the center of the front end face of fixed bracket 1.

[0024] The hot melt extrusion tube 8 is provided in eight sets, and the eight sets of hot melt extrusion tubes 8 are fixedly installed on the rear end face of the fixed card seat 1. The hot melt extrusion tube 8 is connected to the plastic mold 7 through the tube.

[0025] The limiting device 3 is threadedly connected to the inner end face of the positioning bracket 6 via the transmission screw 4, and the inner end face of the limiting device 3 is fixedly clamped with the supporting steel mesh 2.

[0026] The limiting device 3 includes a ball bearing slide 31. A sealing mold base 32 is fixedly installed at the center of the front end face of the ball bearing slide 31, and four sets of limiting slots 33 are equidistantly opened on the inner end face of the sealing mold base 32. A stepper motor 39 is fixedly installed at the center of the rear end face of the ball bearing slide 31, and an active bevel gear 38 is fixedly installed at the output end of the stepper motor 39. Four sets of driven bevel gears 36 are equidistantly rotated and engaged on the inner end face of the ball bearing slide 31 with the active bevel gear 38 as the center. A guide screw 35 is fixedly installed on the inner end face of the driven bevel gear 36. Four sets of sealing seats 34 are equidistantly threadedly connected to the inner end face of the sealing mold base 32 through the guide screw 35. A threaded guide seat 37 is fixedly installed at the center of the lower end face of the sealing seat 34. A one-way exhaust hole 310 is opened on the rear end face of the ball bearing slide 31 opposite to the sealing mold base 32.

[0027] The sealing bracket 34 is threadedly slidably connected to the inner end face of the ball slide 31 by the guide screw 35 and the threaded guide seat 37. The threaded connection between the threaded guide seat 37 and the guide screw 35 can provide sufficient power for the sealing bracket 34 to guide it, which facilitates the subsequent quick and convenient limiting operation of the support steel mesh 2.

[0028] The sealing bracket 34 slides and engages with the inner wall of the sealing mold base 32 through the limiting slot 33. The limiting slot 33 can provide sufficient guiding foundation for the sealing bracket 34, thereby improving the stability of the sealing bracket 34 in limiting the support steel mesh 2.

[0029] The active bevel gear 38 meshes with four sets of driven bevel gears 36. The support steel mesh 2 is fixedly engaged with the inner end face of the sealing mold base 32 by the sliding limit of four sets of sealing brackets 34. The active bevel gear 38 can drive four sets of guide screws 35 to rotate synchronously through the four sets of driven bevel gears 36, which can improve the transmission efficiency of the equipment and improve the adaptability to subsequent limit of different support steel meshes 2.

[0030] The ball bearing slide 31 is threadedly slidably connected to the inner end face of the positioning bracket 6 via the transmission screw 4. The supporting steel mesh 2 is coaxial with the molding mold 7, and the supporting steel mesh 2 does not contact the inner or outer wall of the molding mold 7. This prevents the supporting steel mesh 2 from being exposed after the composite pipe is molded, thus affecting the stability of the composite pipe.

[0031] Working Principle: During use, the operator can connect the composite material hot-melt mechanism to the hot-melt extrusion tube 8 to facilitate the subsequent introduction of the hot-melted material, such as polyethylene, into the molding mold 7 for shaping. When shaping the composite tube, the operator can use an external clamp to position the supporting steel mesh 2 at the coaxial center of the sealing mold base 32. Then, the servo motor 5 is started. The servo motor 5 is threadedly connected to the ball bearing slide 31 through the transmission screw 4, thereby driving the sealing mold base 32 to be limited to the outside of the supporting steel mesh 2. When the supporting steel mesh 2 is limited to the inside of the sealing mold base 32, the stepper motor 39 is started. The stepper motor 39 can synchronously drive four sets of driven bevel gears through the active bevel gear 38. As wheel 36 rotates, four sets of driven bevel gears 36 can be threadedly connected to threaded guide seats 37 via guide screws 35, thereby driving four sets of sealing seats 34 to be limited to the inside of the limiting slots 33, so that the four sets of sealing seats 34 can lock the supporting steel mesh 2. After locking, servo motor 5 continues to drive the sealing mold seat 32 to guide displacement via transmission screw 4, so that the sealing mold seat 32 can be inserted into the plastic mold 7 through the supporting steel mesh 2. At this time, hot melt extrusion tube 8 can introduce hot melt polyethylene into the plastic mold 7, and then cover the outside of the supporting steel mesh 2. After cooling, it is shaped into a composite tube. Then, servo motor 5 flips and drives the completed composite tube out through transmission screw 4 and limiting device 3.
