Description

Technical Field

[0001] This utility model relates to the field of copper tube and rod processing technology, and in particular to a copper tube and rod pressing mold assembly. Background Technology

[0002] With the increasing demands for shape accuracy, dimensional accuracy, and surface quality in industrial production, mold processing technology has been gradually applied to the production of copper tubes and rods. As an important method in mold processing, compression molding can use pressure to cause plastic deformation of the copper tube or rod material within the mold cavity, thereby obtaining high-precision shapes and dimensions.

[0003] However, in existing steel pipe bar molding processes, the length of the load-bearing device is fixed and cannot be adjusted. In actual steel pipe bar production, customer needs are diverse, with varying requirements for pipe bar lengths. If the molding equipment can only mold steel pipe bars of a single length, production cannot be adjusted promptly when orders for different lengths are received. Frequent equipment changes or mold adjustments are needed to accommodate different pipe bar lengths, and each change or adjustment takes time, leading to production interruptions and reduced efficiency. Utility Model Content

[0004] To solve the above problems, this utility model provides a copper tube / rod molding assembly, the specific technical solution of which is as follows:

[0005] A copper tube / bar pressing die assembly includes a pressing die base, a pressing die channel at the center of the pressing die base, a pressing die straightening assembly for pressing the steel tube / bar above the pressing die channel, a pressing die placement assembly and a pressing die adjustment assembly below the pressing die channel, the pressing die placement assembly and the pressing die straightening assembly being symmetrically arranged, the pressing die adjustment assembly having an adjustment frame, the pressing die adjustment assembly being able to move the position of the adjustment frame in the vertical direction, and a pressing die moving assembly for moving the steel tube / bar on the adjustment frame.

[0006] Furthermore, the mold straightening assembly includes a hydraulic cylinder, a connecting seat, and a mold die. The hydraulic cylinder is vertically mounted on the top of the mold base. The connecting seat is connected to the telescopic end of the hydraulic cylinder. Sliding rods are provided at both ends of the connecting seat. A sliding sleeve that slides with the sliding rods is provided on the mold base. A mold connecting block is provided at the bottom of the connecting seat. The mold die is detachably connected to the bottom of the mold connecting block.

[0007] Furthermore, the mold placement assembly includes a drive motor, a support base, a bidirectional drive screw, two guide seats, and two placement blocks. The two guide seats are symmetrically arranged at both ends of the bottom of the mold channel. The drive motor is located in the middle of the mold channel, and the support base is located in the middle of the mold channel. The two ends of the bidirectional drive screw are rotatably connected to the two guide seats, and the middle of the bidirectional drive screw is rotatably connected to the support base. The drive motor is driven by the bidirectional drive screw. The two placement blocks are slidably connected to the two guide seats respectively. Each placement block is provided with a threaded sleeve that is threadedly connected to the bidirectional drive screw, and the bottom of each placement block is provided with a V-shaped placement seat.

[0008] Furthermore, the mold adjustment assembly includes two adjusting cylinders symmetrically arranged on the mold base and a movable frame arranged on both sides of the adjustment frame. The bottom of the adjusting cylinder is hinged to the side wall of the mold base, and the telescopic section of the adjusting cylinder is hinged to the bottom of the adjustment frame. The side wall of the mold base is provided with symmetrically arranged upper and lower limit seats, and the two ends of the movable frame are slidably engaged with the two limit seats.

[0009] Furthermore, the mold adjustment assembly also includes a synchronous shaft, with adjustment gears at both ends of the synchronous shaft, and an adjustment toothed plate that meshes with the adjustment gears on the movable frame.

[0010] Furthermore, the pressing mold moving assembly includes a moving motor mounted on an adjustment frame. The two ends of the adjustment frame are provided with two side moving rollers that are rotatably connected. The middle position of the adjustment frame is provided with three middle moving rollers that are rotatably connected. The moving motor is drivenly connected to one of the two side moving rollers. The two side moving rollers and the middle moving roller are all provided with sprockets, and all sprockets are connected by a chain drive.

[0011] Furthermore, a mold-changing frame is provided between the two placement blocks, and the mold-changing frame is detachably connected to the two placement blocks. Beneficial effects

[0012] Firstly, when supporting copper tubes of different lengths, the two ends of the copper tubes are placed on two V-shaped support seats. The drive motor drives the bidirectional lead screw to rotate on the two guide seats and the two threaded sleeves to rotate. This causes the two support blocks to move towards the center or to the sides, thus supporting copper tubes of different lengths. This improves production flexibility, reduces production costs, and increases production efficiency.

[0013] Secondly, when adjusting the position of the copper tube rod to be pressed, the two adjusting cylinders work synchronously, which can drive the two ends of the adjusting frame to move the moving frame upward on the corresponding limit seat. When the moving frame moves upward, it will drive the moving tooth plate to move on the adjusting gear, thereby driving the synchronous shaft to rotate. This ensures that when the position of the adjusting frame is adjusted in the vertical direction, the adjustment of the two ends of the adjusting frame is synchronized, so that the two ends of the copper tube rod are at the same horizontal position. This ensures the accuracy of the pressing process in the subsequent pressing process. It will not cause inconsistency between the two pressing dies of the copper tube rod due to one end tilting downward or upward, which would affect the accuracy of the pressing of the copper tube rod. In the process of pressing copper tube rods of different sizes, it can also be adjusted so that the two side moving rollers and the middle moving roller on the adjusting frame are on the same horizontal line with the two V-shaped placement seats, ensuring the consistency of the pressing dies at both ends of the steel tube rod.

This disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0023] Reference Figures 1 to 7 This embodiment proposes a design for a copper tube rod pressing mold assembly, including a pressing mold base 1, a pressing mold channel 10 at the middle position of the pressing mold base 1, a pressing mold straightening assembly 2 for pressing the steel tube rod above the pressing mold channel 10, a pressing mold placement assembly 3 and a pressing mold adjustment assembly 4 below the pressing mold channel 10, the pressing mold placement assembly 3 and the pressing mold straightening assembly 2 are symmetrically arranged, the pressing mold adjustment assembly 4 is provided with an adjustment frame 40, the pressing mold adjustment assembly 4 can drive the position of the adjustment frame 40 to move in the vertical direction, and the adjustment frame 40 is provided with a pressing mold moving assembly 5 for driving the steel tube rod to move.

[0024] Preferably, the mold straightening assembly 2 includes a hydraulic cylinder 21, a connecting seat 22, and a mold 23. The hydraulic cylinder 21 is vertically mounted on the top of the mold base 1. The connecting seat 22 is connected to the telescopic end of the hydraulic cylinder 21. The two ends of the connecting seat 22 are respectively provided with sliding rods 24. The mold base 1 is provided with a sliding sleeve 25 that slides with the sliding rods 24. The bottom of the connecting seat 22 is provided with a mold connecting block 26. The mold 23 is detachably connected to the bottom of the mold connecting block 26.

[0025] When the copper tube rod is pressed, the hydraulic cylinder 21 can drive the connecting seat 22 to move downward on the two sliding sleeves 25 through the two sliding rods 24 respectively. The downward movement of the connecting seat 22 will drive the position of the pressing mold connecting block 26 to move downward, thereby driving the position of the pressing mold 23 to move downward, thus performing the pressing molding work on the copper tube rod.

[0026] It should be noted that when molding copper tubes, the molding die 23 can be adjusted and replaced according to the size or length of the copper tube, and different sizes of molding die 23 can be used to mold different types of copper tubes.

[0027] Preferably, the mold placement assembly 3 includes a drive motor 31, a support base 32, a bidirectional drive screw 33, two guide seats 34, and two placement blocks 35. The two guide seats 34 are symmetrically arranged at both ends of the bottom of the mold channel 10. The drive motor 31 is located in the middle of the mold channel 10, and the support base 32 is located in the middle of the mold channel 10. The two ends of the bidirectional drive screw 33 are rotatably connected to the two guide seats 34, and the middle of the bidirectional drive screw 33 is rotatably connected to the support base 32. The drive motor 31 is connected to the bidirectional drive screw 33 in a transmission connection. The two placement blocks 35 are slidably connected to the two guide seats 34 respectively. The placement blocks 35 are provided with threaded sleeves 36 that are threadedly connected to the bidirectional drive screw 33. The bottom of the placement blocks 35 is provided with a V-shaped placement seat 37.

[0028] When carrying copper tubes of different lengths, the two ends of the copper tubes are placed on two V-shaped support seats 37. The drive motor 31 drives the bidirectional lead screw 33 to rotate on two guide seats 34 and drives two threaded sleeves 36 to rotate. This causes the two support blocks 35 to move to the middle or to the sides. This allows for the carrying of copper tubes of different lengths, improving production flexibility, reducing production costs, and increasing production efficiency.

[0029] Preferably, the mold adjustment assembly 4 includes two adjusting cylinders 41 symmetrically arranged on the mold base 1 and a movable frame 42 arranged on both sides of the adjustment frame 40. The bottom of the adjusting cylinder 41 is hinged to the side wall of the mold base 1, and the telescopic section of the adjusting cylinder 41 is hinged to the bottom of the adjustment frame 40. The side wall of the mold base 1 is provided with symmetrically arranged limiting seats 43. The two ends of the movable frame 42 are slidably engaged with the two limiting seats 43. The mold adjustment assembly 4 also includes a synchronous shaft 44. The two ends of the synchronous shaft 44 are respectively provided with adjusting gears 45, and the movable frame 42 is provided with adjusting tooth plates 46 that mesh with the adjusting gears 45.

[0030] When adjusting the position of the copper tube rod to be pressed, the two adjusting cylinders 41 work synchronously to drive the two ends of the adjusting frame 40 to move the moving frame 42 upward on the corresponding limit seat 43. When the moving frame 42 moves upward, it will drive the moving tooth plate to move on the adjusting gear 45, thereby driving the synchronous shaft 44 to rotate. This ensures that when the position of the adjusting frame 40 is adjusted in the vertical direction, the two ends of the adjusting frame 40 are adjusted synchronously, so that the two ends of the copper tube rod are at the same horizontal position. This ensures the accuracy of the pressing process in the subsequent pressing process. It will not cause the two pressing dies of the copper tube rod to be inconsistent due to one end of the copper tube rod tilting downward or upward, which will affect the accuracy of the pressing of the copper tube rod. In the process of pressing copper tube rods of different sizes, it can also be adjusted so that the two moving rollers 52 on both sides and the middle moving roller 53 on the adjusting frame 40 are on the same horizontal line with the two V-shaped placement seats 37, ensuring the consistency of the pressing dies at both ends of the steel tube rod.

[0031] Preferably, the pressing mold moving assembly 5 includes a moving motor 51 mounted on the adjusting frame 40, two side moving rollers 52 rotatably connected at both ends of the adjusting frame 40, and three intermediate moving rollers 53 rotatably connected at the middle position of the adjusting frame 40. The moving motor 51 is connected to one of the two side moving rollers 52 in a transmission connection. Both the two side moving rollers 52 and the intermediate moving rollers 53 are provided with sprockets 54, and all sprockets 54 are connected by chains 55 for transmission.

[0032] When molding a long copper tube rod, the moving motor 51 can drive the moving rollers 52 on both sides to rotate on the adjustment frame 40, thereby driving the three intermediate moving rollers 53 to rotate through the corresponding sprockets 54 and chains 55, moving the position of the copper tube rod forward, and thus performing molding work on different positions of the copper tube rod.

[0033] It should be noted that during the conveying of the copper tube rod, the positions of the two side moving rollers 52 and the three middle moving rollers 53 are adjusted to the same horizontal position as the V-shaped placement seat 37 by the die adjustment assembly 4, so as to convey it forward and perform the die pressing work.

[0034] Preferably, a mold changing frame 6 is provided between the two placement blocks 35, and the mold changing frame 6 is detachably connected to the two placement blocks 35.

[0035] When molding copper tubes, a mold changing frame 6 can be installed between two placement blocks 35 according to the different types of copper tubes, so that the molding die 23 can be replaced. Molding dies 23 of different lengths can be used for molding. During the molding process, the mold changing frame 6 can be removed from the two placement blocks 35 so that the copper tubes can be molded in the future.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
