Description

Technical Field

[0001] This utility model relates to the field of metal plate processing technology, specifically to a hot roller pressing device for metal plate processing. Background Technology

[0002] Roll forming is an important process in metal sheet processing. Roll forming can cause plastic deformation of materials. By using reasonable roll forming parameters and process conditions, the strength and hardness of materials can be enhanced to meet the performance requirements of specific applications.

[0003] Chinese utility model patent CN219425457U discloses a metal plate rolling device: It includes a base plate, a frame fixed to the upper side of the base plate, an electric telescopic rod installed on the upper side of the frame, a movable box fixed to the telescopic end of the electric telescopic rod, slide rails on both sides of the interior of the movable box, and a cylinder installed at the rear of the movable box. A movable plate is fixed to the telescopic end of the cylinder, and two connecting rods are fixed to both ends of the movable plate. Rollers are fixed to the other ends of the two connecting rods. This utility model, through a positioning mechanism, can fix the metal plate, avoiding problems such as uneven force distribution and one end warping when the metal plate is initially rolled.

[0004] However, existing technologies still have shortcomings:

[0005] The above setup pushes the roller to contact the metal plate, and then uses friction to make the roller rotate and crush the metal plate. It is difficult to control the magnitude of the friction. Excessive friction may cause excessive wear on the surface of the metal plate, or even scratches or indentations. On the other hand, insufficient friction may not provide enough driving force to make the roller rotate, affecting the crushing quality and making it difficult to meet the optimal crushing effect for different metal plates and different crushing requirements. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a hot roller pressing device for metal plate processing, which solves the problem in the prior art where the pressing roller is pushed into contact with the metal plate and then rotated by friction to achieve pressing, making it difficult to control the magnitude of friction and affecting the pressing quality.

[0007] To achieve the above objectives, this utility model proposes a hot rolling processing device for metal plate processing, including a processing table, a mounting frame fixedly installed on the processing table, a hydraulic cylinder fixedly installed on the mounting frame, a limit seat fixedly connected to the output shaft of the hydraulic cylinder, a roller fixedly installed inside the limit seat, a pressing roller rotatably installed on the roller, a base plate for placing the metal plate on the processing table, a pair of limit strips for limiting the metal plate slidably installed on the base plate, a bidirectional screw rotatably installed inside the processing table, a pair of threaded sleeves symmetrically installed on the bidirectional screw, an adjusting rod fixedly installed on the threaded sleeves, a second slider fixedly connected to the adjusting rod through the processing table, a second groove opened on the limit strip, and the second slider slidably installed in the second groove.

[0008] As a further embodiment of this utility model: symmetrically spaced grooves are provided on the mounting frame, and support rods are symmetrically fixed at both ends of the limiting seat, with the support rods slidably connected to the limiting grooves.

[0009] As a further embodiment of this utility model: a pair of first sliding grooves are symmetrically provided on the base plate, and the limiting strip is slidably disposed in the first sliding groove.

[0010] As a further embodiment of this utility model: guide grooves are symmetrically provided on the processing table, and the adjusting rod is slidably disposed in the guide grooves.

[0011] As a further embodiment of this utility model: a motor is fixedly installed on the side of the processing table, and the output shaft of the motor is fixedly connected to the bidirectional screw.

[0012] As a further embodiment of this utility model: a door is provided on one side of the processing table, and a bracket is fixedly provided on the opposite side, with an electric push rod fixedly provided on the bracket.

[0013] As a further embodiment of this utility model: the output shaft of the electric push rod is fixedly mounted with an installation strip, and the installation strip is fixedly connected to the base plate.

[0014] As a further embodiment of this utility model: the second slide groove is perpendicular to the first slide groove; a heat-conducting plate is fixedly installed on the processing table, and the heat-conducting plate is located below the base plate.

[0015] As a further embodiment of this utility model: a workbench is fixedly installed inside the processing table, and a heating box is fixedly installed on the workbench, with the heating box located below the heat-conducting plate.

[0016] As a further embodiment of this utility model, a sponge pad is fixedly provided on the limiting strip.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. A base plate is provided, with a first groove on it. A limit strip slides within the first groove, and a second groove is provided on the limit strip, perpendicular to the first groove. A bidirectional screw is rotatably mounted inside the processing table, with a pair of threaded sleeves symmetrically mounted on the bidirectional screw. An adjusting rod is fixedly mounted on the threaded sleeve, and the adjusting rod passes through the processing table and is fixedly connected to a second slider, which slides within the second groove. An electric push rod is fixedly mounted on the processing table, with its output shaft fixedly connected to the base plate. Starting the motor drives the bidirectional screw to rotate, thereby causing the pair of threaded sleeves to move towards each other. The threaded sleeves then drive the pair of adjusting rods to move towards each other, which in turn push the pair of limit strips to move towards each other until the metal plate to be processed is clamped. Starting the electric push rod pushes the base plate to move back and forth, enabling the rolling roller to process the metal plate. This achieves both clamping and rolling of the metal plate in conjunction with the rolling roller.

[0019] 2. By fixing a heat-conducting plate inside the processing table, with the heat-conducting plate located below the base plate and the heating box located below the heat-conducting plate, the heating box is started after the metal plate is clamped, and the metal plate is preheated through the heating box, which improves the plasticity and ductility of the metal plate, which is beneficial for subsequent roll forming.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1-4 As shown, the hot rolling processing device for metal plate processing includes a processing table 1, a mounting frame 2 fixedly installed on the processing table 1, a hydraulic cylinder 3 fixedly installed on the mounting frame 2, a limit seat 6 fixedly connected to the output shaft of the hydraulic cylinder 3, a roller 7 fixedly installed inside the limit seat 6, a rolling roller 8 rotatably installed on the roller 7, a limit groove 15 symmetrically opened on the mounting frame 2, and support rods 9 symmetrically fixed at both ends of the limit seat 6, the support rods 9 being slidably connected to the limit grooves 15. When the hydraulic cylinder 3 is activated, it pushes the limit seat 6 to move, and the movement of the limit seat 6 drives the rolling roller 8 to move until it comes into contact with the metal plate to be processed. When the rolling roller 8 moves down, it drives the support rods 9 to move along the limit grooves 15, which increases the stability of the movement of the rolling roller 8.

[0027] In one embodiment of this invention, a base plate 10 is provided on the processing table 1. The base plate 10 is used to place the metal plate to be processed. A pair of limiting strips 24 are slidably provided on the base plate 10. Driving the pair of limiting strips 24 to move towards each other achieves clamping of the metal plate on the base plate 10. A sponge pad 25 is fixedly provided on the limiting strips 24. The sponge pad 25 can reduce the friction between the limiting strips 24 and the metal plate during clamping. A pair of first sliding grooves 21 are symmetrically opened on the base plate 10. The limiting strips 24 are slidably provided in the first sliding grooves 21. A pair of limiting strips 24 are rotatably provided inside the processing table 1. A pair of threaded sleeves 19 are symmetrically arranged on the double-acting screw 17, located in opposite thread regions of the double-acting screw 17. An adjusting rod 11 is fixedly mounted on each threaded sleeve 19. The adjusting rod 11 passes through the machining table 1 and is fixedly connected to a second slider 23. A second groove 22 is provided on the limiting strip 24, and the second slider 23 is slidably disposed within the second groove 22. Guide grooves 16 are symmetrically provided on the machining table 1, and the adjusting rod 11 is slidably disposed within the guide grooves 16. A motor 4 is fixedly mounted on the side of the machining table 1. The output shaft of the motor 4 is connected to the double-acting screw... Rod 17 is fixedly connected. The starting motor 4 drives the bidirectional screw 17 to rotate, thereby driving a pair of threaded sleeves 19 to move in opposite directions. The threaded sleeves 19 drive a pair of adjusting rods 11 to move in opposite directions. The adjusting rods 11 push a pair of limiting bars 24 to move in opposite directions until the metal plate to be processed is clamped. The limiting bars 24 slide along the first slide groove 21, which further restricts the movement trajectory of the limiting bars 24. A door 5 is provided on one side of the processing table 1, and a bracket 14 is fixedly provided on the opposite side. An electric push rod 12 is fixedly provided on the bracket 14. The output shaft of the electric push rod 12 is fixed. An installation strip 13 is installed and fixedly connected to the base plate 10. After the metal plate is clamped, the hydraulic cylinder 3 is activated to drive the rolling roller 8 to move down to abut against the metal plate to be processed. Then, the electric push rod 12 is activated to push the base plate 10 to move back and forth, so as to realize the rolling processing of the metal plate by the rolling roller 8. The second slide groove 22 is perpendicular to the first slide groove 21. When the base plate 10 moves back and forth, it drives the limiting strip 24 to move back and forth. At this time, the second slider 23 slides in the second slide groove 22. Therefore, it can realize the clamping of the metal plate and the rolling processing of the metal plate in cooperation with the rolling roller 8.

[0028] In one embodiment of this invention, a carrier 20 is fixedly installed inside the processing table 1, and a heating box 18 is fixedly installed on the carrier 20. A heat-conducting plate (not shown in the figure) is fixedly installed on the processing table 1. The heat-conducting plate is located below the base plate 10, and the heating box 18 is located below the heat-conducting plate. The heating box 18 is started to heat the heat-conducting plate, thereby heating the metal plate to be processed. After the metal plate is clamped, the heating box 18 is started to preheat the metal plate, which improves the plasticity and ductility of the metal plate and is beneficial to the roll forming process.

[0029] Working principle:

[0030] The metal plate is placed on the base plate 10. The motor 4 is started to drive the bidirectional screw 17 to rotate, thereby driving a pair of threaded sleeves 19 to move towards each other. The threaded sleeves 19 drive a pair of adjusting rods 11 to move towards each other. The adjusting rods 11 push a pair of limiting bars 24 to move towards each other until the metal plate to be processed is clamped. Then the heating box 18 is started to preheat the metal plate. Next, the hydraulic cylinder 3 is started to push the limiting seat 6 to move. The movement of the limiting seat 6 drives the rolling roller 8 to move until it comes into contact with the metal plate to be processed. Finally, the electric push rod 12 is started to push the base plate 10 to move back and forth, so that the rolling roller 8 can roll the metal plate.
