Description

Technical Field

[0001] This invention relates to the field of extrusion molding technology, and more particularly to a hydraulic mechanical extrusion molding equipment. Background Technology

[0002] Traditional metal profile and structural component processing primarily employs casting and machining processes, which suffer from low material utilization, insufficient forming accuracy, and limited production efficiency. Hydraulic mechanical extrusion molding, using a hydraulic cylinder as a power source, applies high pressure to metal bars, causing them to plastically deform through a die cavity. It offers advantages such as dense forming, excellent mechanical properties, and the ability to continuously produce complex cross-section components, and is widely used in hardware, automotive parts, and industrial profile manufacturing. However, existing hydraulic mechanical extrusion molding equipment still has the following drawbacks during use: Traditional hydraulic metal bar extrusion equipment currently suffers from significant shortcomings in continuous production. It generally cannot achieve continuous and stable extrusion of metal bars, often employing a single-bar feeding and single-extrusion operation mode. After completing one product, the machine must be stopped to await feeding and resetting, resulting in long intervals between processes and low overall production efficiency. Furthermore, the equipment relies on a separate external lubrication mechanism, requiring separate spraying or roller coating after the bar is heated and before it enters the extrusion cylinder. This separation of lubrication and extrusion processes prevents synchronization, increasing auxiliary work time and extending the production cycle per batch. The independent lubrication mechanism not only occupies extra space but also requires dedicated personnel or separate equipment for operation, further reducing the automation level and extrusion efficiency of the production line. The disconnect between bar lubrication and extrusion processes easily leads to uneven coating and lubrication failure, affecting molding quality and requiring repeated shutdowns for recoating, exacerbating production interruptions. Overall, the discontinuous extrusion method and the separate lubrication structure mutually restrict each other, resulting in low equipment operating efficiency and high energy consumption, making it difficult to meet the demands of large-scale, high-efficiency metal product production, and hindering enterprises' capacity expansion and cost control. Summary of the Invention

[0003] In view of the problems of existing technology, such as the inability to achieve continuous and stable extrusion of metal bars and the reliance on independent external lubrication mechanisms for equipment lubrication, a hydraulic mechanical extrusion molding equipment is proposed.

[0004] This application provides a hydraulic mechanical extrusion molding equipment, the purpose of which is to achieve continuous and stable extrusion of metal bars and to set up a mechanism for lubricating the metal bars before extrusion.

[0005] The technical solution of the present invention is as follows: a hydraulic mechanical extrusion molding equipment, including an L-shaped base, a hydraulic cylinder is provided on the L-shaped base, an extrusion rod is provided at the output end of the hydraulic cylinder, an extrusion head is provided on the extrusion rod, a V-shaped plate is provided on the top of the L-shaped base, an extrusion block is also provided on the L-shaped base, an extrusion mold is provided on the extrusion block, a material box is also provided on the extrusion block, and a feeding lubrication unit is also provided on the material box; The feeding and lubrication unit includes a feeding component mounted on a material box, a lubrication component mounted on the feeding component, and a receiving component mounted on an L-shaped base. The feeding component includes a feeding assembly and a rotating assembly mounted on the material box. The feeding component conveys the metal rod evenly towards the front of the extrusion head, the lubrication component lubricates the metal rod, and the receiving component receives the metal rod. The feeding assembly includes a feeding roller mounted on a material box, with several feeding troughs arranged in a circular array on the feeding roller.

[0006] Furthermore, the rotating assembly includes a rotating rod disposed on one side of the material box, the rotating rod being connected to the feeding roller via a one-way bearing, the rotating rod having a threaded groove, a nut being disposed on the threaded groove section of the rotating rod, a smooth rod being disposed on the material box, the smooth rod being slidably connected to the nut, a first spring being disposed between the nut and the material box, and the first spring being sleeved on the rotating rod.

[0007] Furthermore, the lubrication component includes a lubrication assembly, a transmission assembly, a rotation assembly, and a storage assembly disposed on the feed roller; The lubrication assembly includes several lubrication chambers arranged in a ring array on the feed roller, with each lubrication chamber corresponding to a feed groove. Several fine holes are symmetrically distributed between the feed groove and the corresponding lubrication chamber. Several L-shaped holes are also arranged in a ring array on the feed roller, with each L-shaped hole corresponding to a fine hole.

[0008] Furthermore, the transmission assembly includes several transmission rods arranged in a circular array on the feeding roller, each transmission rod corresponding to a feeding trough, and two transmission rollers symmetrically distributed on each transmission rod, the transmission rollers being rotatably connected to the feeding roller.

[0009] Furthermore, the rotating assembly includes a driven gear mounted on the transmission rod, a motor mounted on the extrusion block, a sector gear mounted on the motor output shaft, the sector gear meshing with the driven gear, a frustum block mounted on the transmission rod, a pressing block mounted on one side of the feeding roller, the pressing block slidingly connected to the inclined surface of the frustum block, and a number of circular holes arranged in a circular array on the feeding roller, with a second spring mounted between the transmission rod and the inner wall of the circular holes.

[0010] Furthermore, the storage assembly includes a lubrication box disposed on the feeding roller, the lubrication box being fixedly connected to the material box, a pressing block being fixedly connected to the lubrication box, a transmission rod being rotatably connected to the lubrication box, and a connection hole being provided on the lubrication box, the connection hole communicating with an L-shaped hole.

[0011] Furthermore, the receiving component includes a receiving assembly mounted on an L-shaped base, and the receiving assembly is equipped with an extrusion assembly; The receiving assembly includes receiving plates symmetrically arranged on a V-shaped plate, two T-shaped rods symmetrically arranged on the receiving plate, the T-shaped rods being slidably connected to the V-shaped plate, and a receiving spring being provided between the T-shaped rods and the V-shaped plate, with the receiving spring sleeved on the T-shaped rods.

[0012] Furthermore, the extrusion assembly includes two symmetrically distributed grooves on an L-shaped base. An extrusion plate is provided inside the groove, a trapezoidal block is provided on the receiving plate, and a pressing rod is provided on the extrusion plate. The pressing rod is slidably connected to the inclined side and the bottom edge of the trapezoidal block, and an extrusion spring is provided between the extrusion plate and the inner wall of the groove.

[0013] The beneficial effects of this invention are: Through the linkage design of hydraulic cylinder extension and retraction with feeding roller rotation, automatic feeding and extrusion forming of metal bars can be completed without stopping the machine. When the hydraulic cylinder retracts, the extrusion head drives the nut to slide, which drives the feeding roller to rotate 90 degrees through the rotating rod and one-way bearing, so that the metal bar in the feeding trough falls accurately into the V-shaped plate. When the hydraulic cylinder extends, the first spring drives the nut to reset, and the feeding roller remains stationary to avoid misfeeding. The entire process requires no manual intervention for feeding and resetting, which solves the drawbacks of traditional equipment that requires single-bar extrusion and machine stoppage, significantly shortens the production cycle, and improves the efficiency of large-scale production.

[0014] The feeding and lubrication unit achieves simultaneous feeding and lubrication. The lubrication component precisely delivers lubricating oil to the surface of the metal rod in the feeding groove through the lubrication chamber and fine orifices. The transmission component drives the metal rod to rotate, ensuring even application of lubricating oil. Simultaneously, the storage component, through the cooperation of the lubrication box and L-shaped orifice, supplies oil only when the feeding groove is in a designated position, avoiding lubricating oil waste. Uniform lubrication significantly reduces friction between the metal rod and the extrusion die, minimizing die jamming and scratches, protecting the die, extending its service life, and reducing equipment maintenance costs.

[0015] The combination of the receiving plate and the receiving spring ensures that falling metal bars can be smoothly caught, preventing them from impacting the V-shaped plate and causing surface wear. The extrusion assembly and extrusion head work together to ensure the receiving plate accurately resets, keeping the metal bars stably positioned within the V-shaped plate and preventing displacement during extrusion. Simultaneously, even lubrication prevents scratches and deformation on the product surface, and the unidirectional rotation design of the feed rollers prevents wear on the top metal bars due to extrusion, further guaranteeing product dimensional accuracy and surface quality, reducing the production of defective products, and improving material utilization and product qualification rates.

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Example 1, referring to Figures 1-4 The first embodiment of the present invention provides a hydraulic mechanical extrusion molding device, including an L-shaped base 1, a hydraulic cylinder 11 fixedly connected to the L-shaped base 1, an extrusion rod 12 fixedly connected to the output end of the hydraulic cylinder 11, an extrusion head 13 fixedly connected to the extrusion rod 12, a V-shaped plate 14 fixedly connected to the top of the L-shaped base 1, an extrusion block 15 fixedly connected to the L-shaped base 1, an extrusion die 16 fixedly connected to the extrusion block 15, a material box 17 fixedly connected to the extrusion block 15, and a feeding lubrication unit installed on the material box 17; the feeding... The material lubrication unit includes a feeding component installed on the material box 17, a lubrication component installed on the feeding component, and a receiving component installed on the L-shaped base 1. The feeding component includes a feeding assembly 2 and a rotating assembly 3 installed on the material box 17. The feeding component uniformly conveys the metal rods to the front of the extrusion head 13. The lubrication component is used to lubricate the metal rods, and the receiving component is used to receive the metal rods. The feeding assembly 2 includes a feeding roller 21 rotatably connected to the material box 17. Several feeding grooves 22 are distributed in a circular array on the feeding roller 21.

[0020] Specifically, the metal rods to be processed are pre-placed in the material box 17. The metal rods fall into the inner side of the feeding trough 22. The feeding roller 21 is started to rotate, causing the metal rods to rotate until they reach the bottom of the feeding roller 21. Under the action of gravity, the metal rods fall from the inner side of the feeding trough 22 into the V-shaped plate 14. The hydraulic cylinder 11 is started, driving the extrusion rod 12 and extrusion head 13 to move, pushing the metal rods in the V-shaped plate 14 towards the extrusion die 16. Under the action of the extrusion die 16, plastic deformation occurs, and the formed metal rods are collected by the collection mechanism. Afterward, the hydraulic cylinder 11 retracts to its original position, and the feeding roller 21 rotates again, causing the metal rods inside the feeding trough 22 to rotate back to the bottom of the feeding roller 21 and then fall. The hydraulic cylinder 11 is started again to extrude and form the metal rods. The entire process does not require machine downtime, thus improving production efficiency.

[0021] Reference Figure 3 and Figure 4The rotating assembly 3 includes a rotating rod 31 rotatably connected to one side of the material box 17. The rotating rod 31 is connected to the feeding roller 21 via a one-way bearing. The rotating rod 31 has a threaded groove, and a nut 32 is threadedly connected to the threaded groove section of the rotating rod 31. A smooth rod 33 is also fixedly connected to the material box 17. The smooth rod 33 is slidably connected to the nut 32. A first spring 34 is rotatably connected between the nut 32 and the material box 17. The first spring 34 is sleeved on the rotating rod 31.

[0022] Specifically, when the hydraulic cylinder 11 retracts, the extrusion head 13 will abut against the nut 32. During the retraction process, the extrusion head 13 will drive the nut 32 to slide on the smooth rod 33. Under the action of the threaded groove, it will drive the rotating rod 31 to rotate. A contact sensor is provided at the end of the rotating rod 31. When the nut 32 moves to the end of the rotating rod 31, under the action of the contact sensor, the hydraulic cylinder 11 stops retracting, and the extrusion head 13 stops moving, so as to prevent the extrusion head 13 from continuing to move and causing damage to the rotating rod 31 and the nut 32. When the nut 32 moves to the end of the rotating rod 31, the rotating rod 31 rotates exactly 90 degrees. Under the action of the one-way bearing, the feeding roller 21 rotates 90 degrees, causing the position of the feeding groove 22 to be interchanged, so that the metal bars can fall one by one. At this time, the first spring 34 is stretched. When the hydraulic cylinder 11 extends, it drives the extrusion head 13 to move away from the nut 32. Under the action of the first spring 34, the nut 32 is pulled back. At this time, due to the one-way bearing, the feeding roller 21 does not rotate, so the hydraulic cylinder 11 extends and retracts once, and the feeding roller 21 rotates 90 degrees, causing the metal bars to fall and be extruded.

[0023] Example 2, refer to Figures 5-10 This is the second embodiment of the present invention, which differs from the first embodiment in that: the lubrication component includes a lubrication assembly 4, a transmission assembly 5, a rotation assembly 6, and a storage assembly 7 mounted on the feed roller 21; the lubrication assembly 4 includes a plurality of lubrication cavities 41 arranged in a ring array on the feed roller 21, each lubrication cavity 41 corresponding to a feed groove 22, and a plurality of fine holes 42 symmetrically distributed between the feed groove 22 and the corresponding lubrication cavity 41; the feed roller 21 also has a plurality of L-shaped holes 43 arranged in a ring array, each L-shaped hole 43 corresponding to a fine hole 42.

[0024] Specifically, external lubricating oil enters the lubrication chamber 41 through the L-shaped hole 43, and then flows into the feeding groove 22 through the fine hole 42, lubricating the metal rod in the feeding groove 22. This significantly reduces friction with the mold, minimizes mold jamming and tearing, makes extrusion smoother, protects the mold, and improves product surface quality and molding accuracy.

[0025] Reference Figure 6 and Figure 8The transmission assembly 5 includes several transmission rods 51 arranged in a ring array and movably connected to the feeding roller 21. Each transmission rod 51 corresponds to a feeding trough 22. Two transmission rollers 52 are symmetrically distributed and slidably connected to the transmission rods 51. The transmission rollers 52 are rotatably connected to the feeding roller 21.

[0026] Specifically, when the transmission rod 51 rotates, the transmission roller 52 is connected to the transmission rod 51 by a limiting sliding connection, which causes the transmission roller 52 to rotate, driving the metal rod inside the feeding trough 22 to rotate, so that the lubricating oil flowing out from the fine hole 42 is evenly coated on the metal rod.

[0027] Reference Figures 6-8 The rotating assembly 6 includes a driven gear 61 fixedly sleeved on the transmission rod 51, a motor 62 fixedly connected to the extrusion block 15, a sector gear 63 fixedly connected to the output shaft of the motor 62, the sector gear 63 meshing with the driven gear 61, a frustum block 64 fixedly sleeved on the transmission rod 51, a pressing block 65 fixedly connected to one side of the feeding roller 21, the pressing block 65 slidingly connected to the inclined surface of the frustum block 64, and a number of circular holes distributed in a ring array on the feeding roller 21, with a second spring 66 rotatably connected between the transmission rod 51 and the inner wall of the circular holes.

[0028] Specifically, when the pressure block 65 is not pressing the frustum block 64, the transmission rod 51 is not entering the circular hole, and the second spring 66 is not compressed, the driven gear 61 on the transmission rod 51 does not mesh with the sector gear 63. When the pressure block 65 presses the frustum block 64, causing the transmission rod 51 to enter the circular hole, the second spring 66 is compressed, and the driven gear 61 on the transmission rod 51 will mesh with the sector gear 63. The motor 62 rotates, driving the sector gear 63 to rotate, which in turn drives the driven gear 61 meshing with it to rotate, driving the transmission rod 51 to rotate, causing the transmission roller 52 to rotate, and driving the metal rod to rotate, evenly applying lubricating oil. That is, the metal rod inside the feeding groove 22 on one side of the feeding roller 21 rotates with the rotation of the transmission roller 52, while the metal rods at the top and bottom of the feeding roller 21 and inside the feeding groove 22 on the other side do not rotate. This prevents the metal rod at the top of the feeding roller 21 from being squeezed by other rods, causing wear and affecting the extruded product.

[0029] Reference Figure 10 The storage component 7 includes a lubrication box 71 rotatably connected to the feeding roller 21, the lubrication box 71 being fixedly connected to the material box 17, the pressing block 65 being fixedly connected to the lubrication box 71, the transmission rod 51 being rotatably connected to the lubrication box 71, and the lubrication box 71 having a connection hole 72 that communicates with the L-shaped hole 43.

[0030] Specifically, external lubricating oil enters the lubrication box 71 and then flows into the L-shaped hole 43 through the connecting hole 72. Only when the L-shaped hole 43 coincides with the connecting hole 72 does the lubricating oil in the connecting hole 72 enter the L-shaped hole 43. The L-shaped hole 43 on the feed roller 21 only coincides with the connecting hole 72 when it rotates to one side of the feed roller 21. All other L-shaped holes 43 are sealed by the lubrication box 71. The remaining structure is the same as in Embodiment 1.

[0031] Example 3, referring to Figure 11 This is the third embodiment of the present invention, which differs from the second embodiment in that: the receiving component includes a receiving assembly 8 mounted on an L-shaped base 1, and an extrusion assembly 9 is mounted on the receiving assembly 8; the receiving assembly 8 includes a receiving plate 81 symmetrically distributed and slidably connected to a V-shaped plate 14, and two T-shaped rods 82 symmetrically distributed and fixedly connected to the receiving plate 81, the T-shaped rods 82 being slidably connected to the V-shaped plate 14, and a receiving spring 83 being fixedly connected between the T-shaped rods 82 and the V-shaped plate 14, the receiving spring 83 being sleeved on the T-shaped rods 82.

[0032] Specifically, before the metal rod in the feeding trough 22 falls, the receiving plate 81 is extended, and the two receiving plates 81 form a V-shaped structure to catch the metal rod and prevent it from hitting the V-shaped plate 14 and causing wear. When the receiving plate 81 extends, the T-shaped rod 82 slides on the V-shaped plate 14 and compresses the receiving spring 83. Under the action of the receiving spring 83 resetting, the receiving plate 81 is re-fitted into the inner side of the V-shaped plate 14, so that the metal rod falls stably on the V-shaped plate 14.

[0033] Reference Figure 11 The extrusion assembly 9 includes two symmetrically distributed grooves on the L-shaped base 1. An extrusion plate 91 is slidably connected to the inner side of the groove. A trapezoidal block 92 is fixedly connected to the receiving plate 81. A pressing rod 93 is fixedly connected to the extrusion plate 91. The pressing rod 93 is slidably connected to the inclined side and the bottom edge of the trapezoidal block 92. An extrusion spring 94 is fixedly connected between the extrusion plate 91 and the inner wall of the groove.

[0034] Specifically, one end of the extrusion plate 91 abuts against the extrusion head 13. When the extrusion head 13 moves, it drives the extrusion plate 91 to move, causing the extrusion plate 91 to slide inside the groove, compressing the extrusion spring 94 and driving the pressure rod 93 to move. This causes the pressure rod 93 to slide against the inclined side and lower bottom edge of the trapezoidal block 92. Under the action of the trapezoidal block 92, the receiving plate 81 is pushed towards the top of the V-shaped plate 14, forming a V-shaped structure to catch the falling metal rod. When the extrusion head 13 moves away from the extrusion plate 91, under the action of the extrusion spring 94, the extrusion plate 91 slides back to its original position inside the groove, causing the receiving plate 81 to move downwards and reset, performing the extrusion operation on the metal rod. The remaining structure is the same as in Embodiment 2.

[0035] Based on embodiments 1-3, the working principle of the present invention is as follows: The metal rod to be extruded is placed in the material box 17, and the metal rod will enter the inner side of the feeding groove 22. When the feeding roller 21 rotates, it will drive the metal rod to rotate. The hydraulic cylinder 11 is activated, causing the hydraulic cylinder 11 to retract, driving the extrusion head 13 to move, pushing the nut 32 to slide on the smooth rod 33, causing the rotating rod 31 to rotate at an angle of 90 degrees. The first spring 34 is stretched. When the nut 32 moves to the end of the rotating rod 31, the hydraulic cylinder 11 stops retracting under the action of the contact sensor. When the hydraulic cylinder 11 retracts, it will drive the extrusion plate 91 to slide inside the chute, compressing the extrusion spring 94, causing the pressure rod 93 to slide on the trapezoidal block 92, pushing the receiving plate 81, so that a V-shaped structure is formed between the two receiving plates 81, catching the falling metal rod and preventing the metal rod from hitting the V-shaped plate 14 and causing wear. When the feeding roller 21 rotates the metal rod to one side, the connecting hole 72 aligns and connects with the L-shaped hole 43, allowing the lubricating oil in the lubrication box 71 to enter the L-shaped hole 43 through the connecting hole 72. Under the action of the lubrication chamber 41, the lubricating oil flows out from the fine hole 42. Due to the action of the pressing block 65, the frustum block 64 moves towards the feeding roller 21, causing the transmission rod 51 to slide into the round hole and compress the second spring 66, so that the sector gear 63 meshes with the driven gear 61. The motor 62 is started, driving the sector gear 63 to rotate, which in turn drives the driven gear 61 to rotate, causing the transmission rod 51 to rotate, which in turn drives the transmission roller 52 to rotate, causing the metal rod in the feeding groove 22 to rotate. With the lubricating oil flowing out of the fine hole 42, the metal rod is evenly coated.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
