Description

Technical Field

[0001] The utility model relates to the technical field of machine tool processing, in particular to an upsetting device. Background Art

[0002] Upsetting is a forging process that reduces the height of a workpiece while increasing its cross-section. Existing upsetting machines, such as the "Half-Shaft Upsetting Machine" disclosed in Chinese Utility Model Patent No. CN202222389559.0 (Granted Announcement No. CN217912797U), place the raw material in a die, activate a press, and drive a punch to press the material within the die, shaping it. Once the material is shaped, it is ejected by an ejector cylinder.

[0003] However, for upsetting of aluminum bars, it is necessary to heat the aluminum bars to 350℃-500℃ in an oxygen-free environment. Since the aluminum bars are dry and free of water and oil after heating, and the aluminum bars are prone to adhesion to the mold at high temperatures, demoulding becomes difficult. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an upsetting device capable of preventing a workpiece to be processed from adhering to a mold during demoulding in response to the above-mentioned existing technical status.

[0005] The technical solution adopted by the present invention to solve the above technical problems is as follows: the upsetting device includes multiple working stations, including:

[0006] The upsetting station is equipped with an upsetting mechanism for upsetting the workpiece to be processed to obtain the upsetting workpiece;

[0007] It is characterized in that the working station also includes:

[0008] a spraying station, disposed adjacent to the upsetting mechanism, provided with a spraying mechanism for spraying lubricating liquid onto the upsetting mechanism;

[0009] The upsetting device further includes a main controller. The upsetting mechanism and the spraying mechanism are both connected to the main controller and are configured to control the spraying mechanism to spray the workpiece to be processed and perform upsetting after the spraying is completed.

[0010] To prevent the spraying mechanism from interfering with the upsetting mechanism, the spraying mechanism preferably includes a spray head and a drive mechanism for controlling the movement of the spray head. During the spraying operation, the drive mechanism controls the spray head to move from an initial position to a set position adjacent to the upsetting mechanism, where it sprays lubricating liquid onto the workpiece. After spraying is completed, the drive mechanism controls the spray head to move back to its initial position, preventing the spray head from interfering with the upsetting mechanism.

[0011] In order to enable the driving mechanism to drive the nozzle to move, preferably, the driving mechanism includes a driving source and a transmission rod disposed at the output end of the driving source, and the nozzle is disposed at the distal end of the transmission rod. In this way, the driving source drives the transmission rod to move, so that the nozzle disposed on the transmission rod can follow the movement of the transmission rod.

[0012] In order to programmatically control the movement of the nozzle and the spraying action of the nozzle, the spraying mechanism is preferably further provided with a third controller. The driving source and the nozzle are both connected to the third controller, and the third controller is connected to the main controller. The third controller is configured to control the driving mechanism to move the nozzle to a set position and perform the spraying action. The driving source can be a device with driving capability such as a motor or a cylinder.

[0013] Furthermore, the driving source is a slide cylinder or a guide rail cylinder.

[0014] In order to be able to adjust the spray radius of the nozzle, preferably, the nozzle includes a spray chamber, an upper portion of the spray chamber is provided with an inlet for the lubricating liquid to flow in, and a lower portion of the spray chamber is provided with an outlet for the lubricating liquid to flow out, and the spray chamber is also provided with an adjusting member for adjusting the spray radius of the outlet.

[0015] In order to enable the regulator to have the ability to adjust the spray radius of the outflow outlet, preferably, the regulating member includes an regulating plate that can move up and down relative to the outflow outlet of the spray chamber, and the regulating member also includes an regulating portion located on the regulating plate and a first connecting rod connected between the regulating portion and the regulating plate and axially arranged, the inflow port is arranged on a straight section, and the cross-sectional changes of the regulating portion, the first connecting rod and the regulating plate are along the outflow direction of the lubricating liquid, and are a straight section, a narrowing section and a diffusion section in sequence. Correspondingly, the cross-section of the outflow port is also a diffusion shape that is wide at the bottom and narrow at the top. The regulating portion is provided with a thread, and correspondingly, a threaded portion is provided on the upper part of the spray chamber, and when the regulating plate is rotated, the regulating member can only move up and down in the spray chamber under the limitation of the cross-sectional area of ​​its straight section to change the spray radius of the regulating plate relative to the outflow outlet. Among them, the inlet for the lubricating liquid to flow in is arranged on the straight section. Due to the setting of the narrowing section, the lubricating liquid in the spray chamber will not affect its flow space due to the insertion of the adjusting part. The key to adjusting the spray radius of the outlet is: the cross-section of the diffusion section of the adjusting part and the cross-section of the corresponding outlet are also diffused, wide at the bottom and narrow at the top. When the adjusting part moves to the top, the two have roughly overlapping inclined surfaces, so that the outlet opening is minimized but the spray radius r is maximized; and when the adjusting part moves to the bottom, due to the downward movement of the narrowing section, the offset distance of the inclined surface between the diffusion section of the adjusting part and the corresponding outlet is increased, so that the outlet opening is maximized but the spray radius r is minimized.

[0016] To secure the spray mechanism, the spray station is preferably further provided with a mounting base, located adjacent to the upsetting mechanism. The mounting base includes a second connecting rod and a mounting plate mounted on the second connecting rod. The mounting plate is movable up and down along the second connecting rod, and the spray mechanism is mounted on the mounting plate. This allows the mounting plate to be moved to a desired position on the connecting rod as needed, thereby adjusting the spray mechanism to a desired height.

[0030] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0031] like Figure 1-7 As shown, the upsetting device of this embodiment includes multiple working stations and a main controller 5, wherein the working stations include an upsetting station 1, a spraying station 2, a loading station 3 and a unloading station 4, and the spraying station 2, the loading station 3, the upsetting station 1 and the unloading station 4 are all connected to the main controller 5, and the main controller 5 is configured to: be used to coordinate and complete the spraying, loading, upsetting and unloading work of each station.

[0032] Specifically, the upsetting station 1 is provided with an upsetting mechanism 11 for performing an upsetting process on the workpiece A to be processed and obtaining the upset workpiece A.

[0033] The spraying station 2 is arranged adjacent to the upsetting mechanism 11 and is provided with a spraying mechanism 21 and a mounting seat 22. Specifically, Figure 3-4 As shown, the spraying mechanism 21 is used to spray lubricating liquid on the upsetting mechanism 11. The spraying mechanism 21 includes a nozzle 211, a driving mechanism 212 for controlling the movement of the nozzle 211, and a third controller 213. The driving mechanism 212 includes a driving source 2121 and a transmission rod 2122 provided at the output end of the driving source 2121, and the nozzle 211 is provided at the far end of the transmission rod 2122. The driving source 2121 and the nozzle 211 are both connected to the third controller 213, and the third controller 213 is connected to the main controller 5. The third controller 213 is configured to control the driving mechanism 212 to move the nozzle 211 to a set position and perform a spraying action. In this embodiment, the driving source 2121 is a slide cylinder. When faced with molds of various sizes of the upsetting mechanism 11, the spraying mechanism 21 needs to be able to fully wet the upsetting mechanism 11. For this purpose, the nozzle 211 of the spraying mechanism 21 is designed to have an adjustable spray radius. Specifically, as shown in FIG. Figure 5-6As shown, the nozzle 211 includes a spray chamber 2111, an inlet 2112 for the lubricating liquid to flow in is opened at the upper portion of the spray chamber 2111, and an outlet 2113 for the lubricating liquid to flow out is opened at the lower portion of the spray chamber 2111. The spray chamber 2111 is also provided with an adjusting member 2114 for adjusting the spray radius of the outlet 2113. The adjusting member 2114 includes an adjusting plate 21141 that can move up and down relative to the outlet 2113 of the spray chamber 2111.

The cross-sections of the regulating portion 21142, the first connecting rod 21143 and the regulating plate 21141 change along the outflow direction of the lubricating liquid, and are successively a straight section, a narrowing section and a diffusion section. Correspondingly, the cross-section of the outflow outlet 2113 is also diffused, wider at the bottom and narrower at the top. The regulating portion 21142 is provided with a thread. Correspondingly, a threaded portion 2115 is provided at the upper portion of the spray chamber 2111. When the regulating plate 21141 is rotated, the regulating member 2114 can only move up and down in the spray chamber 2111 under the limitation of its straight section cross-section, so as to change the spray radius of the regulating plate 21141 relative to the outflow outlet 2113. Among them, the inlet 2112 for the lubricating liquid to flow in is set on the straight section. Due to the setting of the narrowed section, the lubricating liquid in the spray chamber 2111 will not be affected by the insertion of the adjusting member 2114. The key to adjusting the spray radius of the outlet 2113 is that the cross-section of the diffusion section of the adjusting member 2114 and the corresponding cross-section of the outlet 2113 also present a diffusion shape with a wide bottom and a narrow top. When the adjusting member 2114 moves to the top, the inclined surfaces of the two roughly overlap, so that the opening of the outlet 2113 is the smallest but the spray radius r is the largest, as shown in FIG. Figure 5 When the regulating member 2114 moves to the bottom, due to the downward movement of the narrowing section, the distance between the inclined surface of the diffuser section of the regulating member 2114 and the corresponding outlet 2113 increases, so that the outlet 2113 opens to the maximum but the injection radius r is the smallest, as shown. Figure 6 shown.

[0034] The mounting base 22 is used to secure the spray mechanism 21. The mounting base 22 is located adjacent to the upsetting mechanism 11 and includes a second connecting rod 221 and a mounting plate 222 mounted on the second connecting rod 221. The mounting plate 222 is movable up and down along the second connecting rod 221, and the spray mechanism 21 is mounted on the mounting plate 222. The mounting plate 222 can be moved to a desired position on the second connecting rod 221 as needed, thereby adjusting the spray mechanism 21 to a desired height.

[0036] The unloading station 4 is equipped with an unloading mechanism for unloading the upset workpiece A, thereby removing the upset workpiece A from the upset station 1. To control the unloading mechanism, the unloading mechanism is a second robot 41. The second robot 41 includes a second controller 411, a second robotic arm 412, and a second gripping mechanism 413 provided on the second robotic arm 412.
