Description

Technical Field

[0001] The invention belongs to the technical field of cold pressing processing, and in particular relates to a cold pressing forming machine tool for metal mechanical parts and a use method thereof. Background Art

[0002] Cold forming uses the plastic deformation of metal to manufacture parts with the desired shape, which can greatly reduce the amount of cutting to improve material utilization. With the continuous improvement of product technology requirements in various industries, cold forming production technology has gradually become the development direction of refined production of small and medium-sized forgings. Compared with other processing technologies, cold pressed workpieces can obtain ideal surface roughness and dimensional accuracy. Parts processed by cold extrusion rarely need to be reprocessed, and only fine grinding is required in areas with particularly high requirements. At the same time, the cold working hardening of the metal after cold extrusion and the formation of a reasonable fiber streamline distribution in the parts make the strength of the parts much higher than that of the raw materials.

[0003] In the existing technology, for the cold pressing processing of the head of columnar metal materials, the traditional cold pressing technology is that the operator places the columnar metal material upright on the lower mold, and after the upper mold presses and fixes the top of the columnar metal material, the columnar metal material is released and the cold pressing processing is completed by the cold pressing head. This cold pressing processing method has the risk of hand pinching.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] For specific embodiment 1, please refer to Figure 1-12 The present invention is a cold pressing forming machine tool for metal mechanical parts, comprising a cold pressing bearing assembly 1, a double-station control structure 4 and a material picking mechanism 8; the cold pressing bearing assembly 1 comprises a lifting cold pressing head 2, and an alternating conveying platform 3 is provided below the cold pressing head 2; the double-station control structure 4 comprises a double-sided material guide assembly 5 which reciprocates along the alternating conveying platform 3, and a first supporting mechanism 6 and a second supporting mechanism 7 are respectively installed at the workstations on the double-sided material guide assembly 5; the material picking mechanism 8 is symmetrically installed on both sides of the cold pressing bearing assembly 1 and is located above the alternating conveying platform 3, the material picking mechanism 8 comprises a material discharge port 9, a magnetic suction seat 10 and a material discharge conduit 11, the magnetic suction seat 10 and the material discharge conduit 11 move synchronously, and the magnetic suction seat 10 is initially concentrically aligned with the material discharge port 9, and the material discharge port 9 and the magnetic suction seat 10 are at corresponding material picking positions.

[0033] Among them, the first supporting mechanism 6 and the second supporting mechanism 7 both include a cold-pressed supporting assembly 12, and a lifting assembly 13 for supporting columnar parts is slidingly provided inside the cold-pressed supporting assembly 12. A spiral conveying assembly 14 extending into the inner cavity of the cold-pressed supporting assembly 12 is installed on the double-sided material guide assembly 5. The spiral conveying assembly 14 includes a spiral track plate 15 that is fitted with the lifting assembly 13. The spiral track plates 15 between the first supporting mechanism 6 and the second supporting mechanism 7 rotate synchronously and in opposite spiral directions, so that the synchronous reverse movement of the columnar part 53 to be cold-pressed and the cold-pressed columnar part 54 can be achieved, that is, when the columnar part 53 to be cold-pressed is controlled to gradually move upward, the cold-pressed columnar part 54 gradually moves downward.

[0034] In some embodiments, as Figure 2 and Figure 3 As shown, the cold press bearing assembly 1 also includes a cold press bearing frame 16, a hydraulic cylinder 17 is installed on the top of the cold press bearing frame 16, and the output end of the hydraulic cylinder 17 is connected to the cold press head 2 (the cold press head 2 is installed in a detachable manner), and the alternating conveying platform 3 is fixed inside the cold press bearing frame 16, a track groove 18 is provided on the top of the alternating conveying platform 3, and a guide channel 19 connected to the track groove 18 is provided at the bottom of the alternating conveying platform 3. A power screw 20 is rotatably provided at the bottom of the alternating conveying platform 3, and the power screw 20 is connected to the output end of the power motor 21 at the bottom of the alternating conveying platform 3. When the power screw 20 is controlled to rotate by the power motor 21, the threaded matching relationship between the power screw 20 and the double-station control structure 4 can be utilized to drive the entire double-station control structure 4 to reciprocate along the alternating conveying platform 3, and the double-station control structure 4 reciprocates between the material taking stations on the left and right sides.

[0035] In some embodiments, as Figure 4 As shown, the double-sided material guide assembly 5 includes an annular carrier 22 attached to the top of the alternating conveying platform 3, a track seat 23 that slides with the track groove 18 is fixed to the bottom of the annular carrier 22, and an internal thread seat 24 that is fixed to the track seat 23 is provided at the bottom of the alternating conveying platform 3. The internal thread seat 24 slides with the guide channel 19, and the internal thread seat 24 is sleeved on the power screw 20 and the two are threadedly connected. Two oblique material guide channels 25 are symmetrically fixed on the top of the annular carrier 22. In the initial state, the first supporting mechanism 6 is directly below the cold pressing head 2, and the second supporting mechanism 7 is directly below the material taking station on the left (as shown in FIG. Figure 1 As shown), when the power motor 21 is controlled by the control system to operate once, the entire double-station control structure 4 can be moved to the right to the set position. At this time, the second supporting mechanism 7 is directly below the cold pressing head 2, and the first supporting mechanism 6 is directly below the material taking station on the right.

[0036] In some embodiments, as Figure 7 and Figure 8As shown, the cold pressing support assembly 12 includes a cold pressing support part 26 installed on the annular carrier 22. The cold pressing support part 26 is a hollow tube structure. A cold pressing support platform 27 is installed on the top of the cold pressing support part 26. A positioning hole 28 coaxial with the cold pressing support platform 27 is opened on the top of the cold pressing support platform 27. Two limiting protrusions 29 are symmetrically fixed on the inner wall of the cold pressing support part 26. The positioning hole 28 is mainly used for positioning the columnar parts 53 to be cold pressed and the cold pressed columnar parts 54 during the cold pressing process, so that the columnar parts 53 to be cold pressed and the cold pressed columnar parts 54 can always be kept in a vertical state during the cold pressing process. At the same time, under the action of the limiting protrusions 29, the entire lifting assembly 13 can be guaranteed to move up and down smoothly.

[0037] Furthermore, the lifting assembly 13 includes a lifting seat 30 that is slidably fitted inside the cold press supporting portion 26. A positioning groove 31 with a diameter larger than the positioning hole 28 is provided on the top of the lifting seat 30 (that is, it can support and position columnar parts of different models. The cold press supporting platform 27 can be replaced according to the model of the columnar part, so that the positioning hole 28 on the cold press supporting platform 27 can adapt to the corresponding model of columnar parts). The inner wall of the positioning hole 28 fits on the peripheral side of the columnar part. A limiting hole 32 that is compatible with the limiting protrusion 29 is provided on the peripheral side of the lifting seat 30. A vertical force-bearing member 33 is fixedly provided at the bottom of the lifting seat 30. The limiting guidance of the entire lifting assembly 13 during vertical movement can be achieved through the cooperation between the limiting protrusion 29 and the limiting hole 32.

[0038] In some embodiments, as Figure 4 、 Figure 5 and Figure 6 As shown, the spiral conveying assembly 14 also includes a support seat 34 installed at the bottom of the annular carrier 22, a support control motor 35 is installed on the top of the support seat 34 on the first supporting mechanism 6, and a transmission shaft 36 is connected to the output end of the support control motor 35. The top of the support seat 34 on the second supporting mechanism 7 is rotatably provided with a transmission shaft 36, and the upper end of the transmission shaft 36 extends into the inner cavity of the cold-pressed supporting portion 26 and the two are rotatably connected. The spiral track plate 15 is fixed on the side surface of the transmission shaft 36 and is located in the inner cavity of the cold-pressed supporting portion 26. The bottom of the vertical force-bearing member 33 abuts against the spiral track plate 1 5, a transmission wheel 37 is fixedly mounted on the transmission shaft 36, and the two transmission wheels 37 are connected by a transmission belt 38. When the support control motor 35 is started, the support control motor 35 controls the corresponding transmission shaft 36 to rotate, thereby driving the spiral track plate 15 on the first support mechanism 6 to rotate. Under the combined action of the transmission belt 38 and the two transmission wheels 37, the spiral track plate 15 on the second support mechanism 7 is driven to rotate synchronously, thereby achieving synchronous reverse movement of the lifting assembly 13 of the first support mechanism 6 and the lifting assembly 13 of the second support mechanism 7.

[0039] In the initial state, the first supporting mechanism 6 is directly below the cold pressing head 2, and the second supporting mechanism 7 is directly below the material picking station on the left. At this time, the lifting assembly 13 on the second supporting mechanism 7 is in the highest position of the inner cavity of the cold pressing supporting assembly 12 (that is, the lifting seat 30 on the second supporting mechanism 7 is against the bottom of the corresponding cold pressing supporting platform 27). After a columnar part 53 to be cold pressed is inserted into the positioning port 28 on the second supporting mechanism 7 and supported by the positioning groove 31, the power screw 20 is controlled by the power motor 21 to rotate, so that the entire double-station control structure 4 moves to the right to the set position. At this time, the second supporting mechanism 7 is directly below the cold pressing head 2, and the first supporting mechanism 6 is directly below the material picking station on the right. In this process, the two spiral track plates 15 between the first supporting mechanism 6 and the second supporting mechanism 7 are controlled by the support control motor 35 to rotate synchronously, so that the lifting assembly 13 on the second supporting mechanism 7 gradually moves downward, and the lifting assembly 13 drives The top of the head of the columnar part 53 to be cold-pressed is cold-pressed to form a notch, and the columnar part 53 to be cold-pressed is cold-pressed into a cold-pressed columnar part 54. During the cold-pressing process, the guiding and positioning effect of the positioning opening 28 and the positioning groove 31 on the columnar part 53 to be cold-pressed, and the supporting effect of the cold-pressing supporting platform 27 on the head of the columnar part 53 to be cold-pressed, can be effectively avoided from axial deviation of the columnar part 53 to be cold-pressed during the cold-pressing process, thereby ensuring the cold-pressing quality of the columnar part 53 to be cold-pressed.

[0040] Next, the next columnar part 53 to be cold-pressed is inserted into the positioning port 28 on the first supporting mechanism 6 and supported by the positioning groove 31. The power screw 20 is controlled by the power motor 21 to rotate in the opposite direction, so that the entire double-station control structure 4 moves to the left to the set position. At this time, the first supporting mechanism 6 is directly below the cold pressing head 2, and the second supporting mechanism 7 is directly below the material-retrieving station on the left. In this process, the two spiral track plates 15 between the first supporting mechanism 6 and the second supporting mechanism 7 are controlled by the supporting control motor 35 to rotate in the opposite direction synchronously, so that the lifting assembly 13 on the first supporting mechanism 6 gradually moves downward, and the lifting assembly 13 drives the columnar part to be cold-pressed thereon. The part 53 moves downward synchronously until the head of the columnar part 53 to be cold-pressed on the first supporting mechanism 6 abuts against the top of the corresponding cold-pressing supporting platform 27. At this time, the lifting assembly 13 on the second supporting mechanism 7 is at the highest position (that is, the lifting seat 30 on the second supporting mechanism 7 abuts against the bottom of the corresponding cold-pressing supporting platform 27). Then, the hydraulic cylinder 17 controls the lifting and lowering of the cold pressing head 2 to complete the cold pressing processing of the columnar part 53 to be cold-pressed. After the cold pressing, the top of the head of the columnar part 53 to be cold-pressed is cold-pressed to form a notch. In this way, the columnar part 53 to be cold-pressed is cold-pressed into a cold-pressed columnar part 54. At this time, the cold-pressed columnar part 54 on the second supporting mechanism 7 is ejected to the highest position (such as Figure 1 As shown), the head of the cold-pressed columnar part 54 on the first supporting mechanism 6 is also against the top of the corresponding cold-pressing supporting platform 27 (as shown). Figure 1 As shown), the cold-pressed columnar component 54 on the second supporting mechanism 7 is then taken out and the next columnar component 53 to be cold-pressed is placed.

[0041] Then, the power screw 20 is controlled to rotate by the power motor 21 again, so that the entire double-station control structure 4 moves to the right to the set position. In this process, the two spiral track plates 15 between the first supporting mechanism 6 and the second supporting mechanism 7 are controlled by the support control motor 35 to rotate synchronously, so that the lifting component 13 on the second supporting mechanism 7 gradually moves downward, and the lifting component 13 drives the columnar part 53 to be cold-pressed thereon to move downward synchronously until the head of the columnar part 53 to be cold-pressed on the second supporting mechanism 7 rests on the top of the corresponding cold-pressing support platform 27. At this time, the first The lifting seat 30 on the supporting mechanism 6 rests against the bottom of the corresponding cold pressing supporting platform 27, and the cold pressed columnar part 54 on the first supporting mechanism 6 is pushed out to the highest position. When the cold pressing head 2 is lifted and lowered by the hydraulic cylinder 17 to complete the cold pressing process of the columnar part 53 to be cold pressed, the cold pressed columnar part 54 on the first supporting mechanism 6 is taken out and the next columnar part 53 to be cold pressed is placed. In this way, the cold pressing process of batches of columnar parts 53 to be cold pressed can be realized successively according to the same control method as mentioned above. The work efficiency of cold pressing process is greatly improved through this double-station alternating operation mode.

[0042] Specific embodiment 2, based on specific embodiment 1, as Figure 9 and Figure 10 As shown, the material picking mechanism 8 includes a material picking power assembly 39; wherein the material picking power assembly 39 includes a material picking carrier 40 mounted on the cold pressing carrier frame 16 (the material picking carrier 40 is mounted on the cold pressing carrier frame 16 by fixing bolts 55 and fastening nuts 56), and a material picking cylinder 41 and a guide shaft 42 are respectively installed at the bottom of the material picking carrier 40, and a material discharge port 9 and a limiting slide 43 are respectively opened on the material picking carrier 40. In the initial state, the magnetic suction seat 10 is concentrically aligned with the material discharge port 9, and an electromagnet is installed at the bottom of the magnetic suction seat 10. The diameter of the magnetic suction seat 10 is smaller than the head of the cold pressed columnar part 54. The notch on the part is used to ensure that the head of the cold-pressed columnar part 54 at the material-retrieving station can be adsorbed and fixed on the magnetic suction seat 10 under the action of magnetic attraction. When the cold-pressed columnar part 54 at the position of the first supporting mechanism 6 or the second supporting mechanism 7 is ejected to the highest position, the head of the cold-pressed columnar part 54 is close to the bottom of the magnetic suction seat 10. Subsequently, the electromagnet on the magnetic suction seat 10 at the corresponding position is controlled to be energized and magnetized, so that the cold-pressed columnar part 54 can be adsorbed and fixed to the magnetic suction seat 10 by using the magnetic attraction. At this time, the bottom of the cold-pressed columnar part 54 is completely out of the positioning port 28.

[0043] In some embodiments, as Figure 9 、 Figure 11 and Figure 12 As shown, the material picking mechanism 8 also includes a material picking component 44; wherein the material picking component 44 includes a first mobile frame 45 located above the material picking carrier 40 and cooperating with the limiting slide 43, a second mobile frame 46 fixed to the first mobile frame 45 is provided below the material picking carrier 40, the second mobile frame 46 is slidably sleeved between the two guide shafts 42, an L-shaped support plate 47 is fixed to the bottom of the second mobile frame 46, the magnetic suction seat 10 and the discharge pipe 11 are both installed on the L-shaped support plate 47, the second mobile frame 46 is connected to the output end of the material picking cylinder 41 Connection; a sealing plate 48 is installed between the second movable frame 46 and the discharge duct 11, the top surface of the sealing plate 48 is fitted against the bottom of the material picking carrier 40, and the top surface of the sealing plate 48 is flush with the top of the discharge duct 11, and an upper guide ring 49 and a lower guide ring 50 which are coaxial with the discharge duct 11 are provided above the discharge duct 11, and the upper guide ring 49 and the lower guide ring 50 are connected to the first movable frame 45 by a horizontal support plate 51, and the lower guide ring 50 is slidably fitted against the top of the material picking carrier 40, and an arc-shaped guide plate 52 is fixed between the upper guide ring 49 and the lower guide ring 50.

[0044] After the cold-pressed columnar part 54 is adsorbed and fixed on the magnetic suction seat 10, the second movable frame 46 is controlled by the material-taking cylinder 41 to move in the direction away from the cold-pressing bearing frame 16 until the discharge pipe 11 is concentrically aligned with the discharge port 9. At this time, the columnar part 53 to be cold-pressed between the upper guide ring 49 and the lower guide ring 50 falls along the discharge port 9 into the discharge pipe 11, and falls along the discharge pipe 11 and is inserted into the positioning port 28 and supported by the positioning groove 31 (at this time, the top surface of the head of the columnar part 53 to be cold-pressed is lower than the bottom of the discharge pipe 11). The magnetic suction seat 10 adsorbs the cold-pressed columnar part 54 and moves it to the oblique guide on the corresponding side. Above the material channel 25, the electromagnet on the magnetic suction seat 10 is controlled to be powered off and demagnetized, so that the cold-pressed columnar parts 54 on the magnetic suction seat 10 fall into the inclined material guide channel 25 for collection, and then the second movable frame 46 is controlled by the material-taking cylinder 41 to move toward the direction close to the cold-pressing support frame 16 until it is reset. At this time, the magnetic suction seat 10 is re-concentrically aligned with the discharge port 9, thereby realizing the automatic loading and unloading action of the columnar parts during the cold pressing process. Through this cold pressing processing method, not only the automation degree of the entire cold pressing process is achieved, but also the risk of the operator's hands being pinched during the cold pressing process is effectively avoided.

By controlling the synchronous rotation of the two spiral track plates (15), the lifting assembly (13) on the second supporting mechanism (7) drives the columnar part (53) to be cold-pressed to move downward until the head of the columnar part (53) to be cold-pressed on the second supporting mechanism (7) abuts against the top of the corresponding cold pressing support platform (27). At this time, the lifting seat (30) on the first supporting mechanism (6) abuts against the bottom of the corresponding cold pressing support platform (27). Then, the cold pressing head (2) is controlled to move up and down by the hydraulic cylinder (17) to complete the cold pressing process of the columnar part (53) to be cold-pressed. S02, insert the next columnar part (53) to be cold pressed into the positioning opening (28) on the first supporting mechanism (6) and support it through the positioning groove (31), control the first supporting mechanism (6) to move to the bottom of the cold pressing head (2), and the second supporting mechanism (7) to move to the bottom of the left material taking station, and control the synchronous reverse rotation of the two spiral track plates (15) so that the lifting assembly (13) on the first supporting mechanism (6) drives the columnar part (53) to be cold pressed thereon to move downward synchronously until the columnar part (53) to be cold pressed on the first supporting mechanism (6) is moved downward synchronously. The head of the pressed columnar part (53) abuts against the top of the corresponding cold pressing support platform (27), and at this time, the lifting seat (30) on the second supporting mechanism (7) abuts against the bottom of the corresponding cold pressing support platform (27), and then the cold pressing head (2) is controlled by the hydraulic cylinder (17) to lift and lower to complete the cold pressing process of the columnar part (53) to be cold pressed. At this time, the cold pressed columnar part (54) on the second supporting mechanism (7) is ejected, and then the cold pressed columnar part (54) on the second supporting mechanism (7) is taken out and the next columnar part (53) to be cold pressed is placed; S03, control the entire double-station control structure (4) to move to the right to the set position again, and control the two spiral track plates (15) to rotate synchronously again during this process, so that the lifting assembly (13) on the second supporting mechanism (7) drives the columnar part (53) to be cold-pressed thereon to move downward synchronously, until the head of the columnar part (53) to be cold-pressed on the second supporting mechanism (7) abuts against the top of the corresponding cold-pressing support platform (27), and at this time, the lifting seat (30) on the first supporting mechanism (6) abuts against the bottom of the corresponding cold-pressing support platform (27), and the cold-pressed columnar part (54) on the first supporting mechanism (6) is ejected.

After the cold-pressed columnar part (54) is adsorbed and fixed on the magnetic suction seat (10), the second movable frame (46) is controlled by the material taking cylinder (41) to move in a direction away from the cold-pressing bearing frame (16) until the discharge pipe (11) is concentrically aligned with the discharge port (9). At this time, the columnar part (53) to be cold-pressed between the upper guide ring (49) and the lower guide ring (50) falls along the discharge port (9) into the discharge pipe (11), and falls along the discharge pipe (11) and is inserted into the positioning port (28) and supported by the positioning groove (31). The magnetic suction seat (10) adsorbs the cold-pressed columnar part (54) and moves to the upper side of the inclined guide channel (25) on the corresponding side; S06, control the electromagnet on the magnetic suction seat (10) to be powered off and demagnetized, so that the cold-pressed columnar parts (54) on the magnetic suction seat (10) fall into the inclined guide channel (25) for collection, and then control the second movable frame (46) to move toward the cold-pressing bearing frame (16) through the material-taking cylinder (41) until it is reset.
