This invention discloses an integrated processing device for straightening and trimming for forgings, comprising a frame, a lower template with a forming through hole on the frame, a support plate mounted below the lower template, and a support mechanism on the frame. The support mechanism allows the support plate to move relative to the lower template so that its upper surface contacts or disengages from the bottom plate of the lower template. When the support plate contacts the lower template, the forming through hole and the lower template form a forming groove. An upper template with forming protrusions and a trimming tool is mounted above the lower template and can move vertically relative to the lower template. A guide plate located below the lower template is mounted on the frame and is positioned below the support plate to receive workpieces falling from the forming through hole. This invention innovatively proposes a new device for trimming and straightening forgings, ensuring that trimming and straightening can be performed on a single mold while facilitating material unloading.

Description

Technical Field

[0001] This invention relates to the field of mold technology for automobile front axle forging, and in particular to an integrated processing device for straightening and trimming for forging. Background Technology

[0002] The front axle is a crucial safety component in the automotive chassis system. Front axles are typically manufactured using either hot forging or a combination of hot and cold forging processes. Taking the hot and cold forging process as an example, the front axle forging process includes: heating round steel, hot forging billet preparation, bending, pre-forging, final forging, trimming, and hot straightening.

[0003] The current process involves forging the front axle of a car and then trimming the edges. After trimming, the process is switched to a straightening process. The temperature of the forged part after trimming is lower than that of the hot-straightened forging. During this process, the forging part needs to be moved to the straightening mold, which is cumbersome and increases the workload of workers to a certain extent, and the production efficiency is relatively low. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention proposes an integrated processing device for straightening and trimming of forgings.

[0005] The present invention proposes an integrated straightening and trimming processing device for forging processing, comprising a frame, a lower template on the frame, a forming through hole on the lower template, a support plate installed below the lower template, and a support mechanism on the frame. The support mechanism moves the support plate relative to the lower template so that the upper surface of the support plate contacts or separates from the bottom plate of the lower template. When the support plate contacts the lower template, the forming through hole forms a forming groove with the lower template.

[0006] An upper template is provided above the lower template. The upper template has a forming protrusion and a cutting tool. The cutting tool is located on the outer periphery of the forming protrusion. The forming protrusion and the forming groove form a cavity. The upper template can move vertically relative to the lower template.

[0007] The frame is provided with a guide plate located below the lower template. The guide plate is located below the support plate and is used to receive the workpiece falling from the forming through hole.

[0008] Preferably, during the processing: the workpiece is placed in the forming groove, the upper template moves downward for the first time to allow the cutting tool to cut the edge of the workpiece; the upper template moves downward for the second time to allow the upper and lower templates to complete the correction of the workpiece; after the correction is completed, the upper surface of the support plate is separated from the lower bottom surface of the lower template, and then the upper template moves downward for the third time to allow the workpiece to be punched out of the forming through hole.

[0009] Preferably, the lower template is provided with a heating element for heating the lower template. When the upper template and the lower template are used to calibrate the workpiece, the heating element heats the lower template to perform heating calibration.

[0010] Preferably, the lower template has a cooling channel, and after heating and correcting one end for a period of time, the workpiece is cooled down through the cooling channel to further increase the correction effect.

[0011] Preferably, coolant is introduced into the cooling channel.

[0012] Preferably, the lower template has an outlet and an inlet communicating with the cooling channel, the outlet being located at the bottom of the lower template and the inlet being located on one side of the lower template.

[0013] Optionally in some embodiments, the support mechanism is a lifting member, and the support plate is installed on the telescopic end of the lifting member.

[0014] Optionally in some embodiments, the support plate is rotatably mounted on the lower template, and the support mechanism is installed between the support plate and the frame.

[0015] Preferably, the upper surface of the guide plate is an inclined surface that gradually slopes upward from the side near the guide plate to the side away from the guide plate, which facilitates material discharge.

[0016] Preferably, the assembly also includes a telescopic component, through which the forming protrusion is mounted on the upper template. The telescopic component is used to drive the forming protrusion to rise and fall relative to the upper template, thereby further facilitating the cutting, correction, and blanking of the workpiece, and thus increasing the processing accuracy.

[0017] The integrated processing device for straightening and trimming of forgings proposed in this invention is a pioneering new device for trimming and straightening forgings. It ensures that trimming and straightening can be performed on a single mold while also facilitating material unloading. The device achieves trimming and straightening of the workpiece by using forming protrusions and trimming tools on the upper mold and by moving the lower mold plate multiple times relative to the lower mold plate. At the same time, the device is designed with a guide plate, a lower forming mold plate, a support plate, and a support mechanism to facilitate the unloading of the workpiece from the forming groove, thereby improving production efficiency.

[0018] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0025] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figures 1-5 (It should be noted that the accompanying drawings in the specification are only to illustrate the technical concept of this application, and some specific structures have been simplified or deleted.) The device for straightening and trimming of forgings includes a frame 1, on which a lower template 2 is provided. Specifically, the lower template 2 has an extension 20 extending outward from the middle of its outer side. The frame 1 has a mounting plate 10, on which a mounting through hole 100 and a mounting groove 101 are opened. The mounting groove 101 is opened on one side of the mounting through hole 100. The lower template 2 is fitted into the mounting through hole 100. The extension 20 matches the mounting groove 101, and the extension 20 is fixed to the mounting plate 10 by existing fixing bolts or other fasteners.

[0027] The lower template 2 has a forming through hole 21, and a support plate 3 is installed below the lower template 2. The frame 1 also includes a support mechanism 4. The support mechanism 4 moves the support plate 3 relative to the lower template 2 so that the upper surface of the support plate 3 contacts or separates from the bottom plate 13 of the lower template 2. When the support plate 3 contacts the lower template 2, the forming through hole 21 and the lower template 2 form a forming groove. The depth of the forming through hole 21 is equal to the thickness of the workpiece, so that the waste edge of the workpiece is located on the upper surface of the lower template 2.

[0028] An upper template 5 is provided above the lower template 2. The upper template 5 has a forming protrusion 6 and a cutting blade 7. The cutting blade 7 is located on the outer periphery of the forming protrusion 6. The forming protrusion 6 and the forming groove form a cavity. The upper template 5 can move vertically relative to the lower template 2.

[0029] Similar to existing technologies, the upper template 5 and the lower template 2 are provided with a guide positioning mechanism, which includes a guide post 8 installed on the lower template 2 and a guide through hole 50 opened on the upper template 5. The guide post 8 slides in the guide through hole 50, thereby ensuring processing accuracy.

[0030] Similar to existing technologies, the frame 1 is also equipped with a lifting drive component (not shown in the figure) that drives the upper template 5 to rise and fall. This lifting drive component can be a hydraulic cylinder as used in existing technologies.

[0031] The frame 1 is provided with a guide plate 9 located below the lower template 2. The guide plate 9 is located below the support plate 3 and is used to receive the workpiece falling from the forming through hole 21.

[0032] During the processing:

[0033] Edge trimming: First, rotate the support plate 3 so that the support plate 3 is directly below the lower template 2. Then, the lifting component rises to support and fix the lower template 2. Place the forged car front axle in the forming groove. Then, place the workpiece in the forming groove. The scrap of the workpiece is located on the upper surface of the upper template 5. The lifting drive component drives the upper template 5 to move downward for the first time so that the edge trimming knife 7 trims the workpiece.

[0034] Correction process: Then, the upper template 5 is moved upward by the lifting drive mechanism, and the lifting drive mechanism is moved downward by the upper template 5 again. The specific moving speed is set according to the actual situation. The upper template 5 and the lower template 2 complete the correction of the workpiece.

[0035] Unloading: After the workpiece is aligned and stuck in the forming through hole 21, the lifting component moves downward. At this time, the workpiece generally will not detach from the lower template 2. Then, the upper template 5 moves downward for the third time, so that the forming protrusion 6 exerts a downward impact force on the workpiece, causing the workpiece to detach from the forming through hole 21 and fall onto the guide plate 9 to complete the unloading.

[0036] It should be noted that, throughout the process, the impact force of the forming protrusion 6 on the workpiece can be controlled by controlling the downward movement speed of the lower die or the maximum height of the lower die relative to the upper die.

[0037] Those skilled in the art can adjust the number of trimming and correction operations according to the actual situation.

[0038] Optionally, the support mechanism 4 can be a support column. When the upper surface of the support plate 3 contacts the bottom of the lower template 2, the support column is installed between the frame 1 and the support plate 3. When the material is dropped, the support column is disassembled so that the support plate 3 can rotate relative to the lower template 2, thereby facilitating the dropping of the material. In this embodiment, preferably, the support mechanism 4 is a lifting component. The lifting component is a hydraulic cylinder, electric cylinder, or other component that can achieve vertical lifting in the prior art. The lifting component is installed on the frame 1. When the upper surface of the support plate 3 is in contact with the bottom surface of the lower template 2, the lifting component rises to support the bottom of the support plate 3.

[0039] The support plate 3 can be placed directly on the lifting component to achieve contact or detachment from the lower template 2 (e.g.) Figure 3 (as shown),

[0040] In some embodiments, one side of the support plate 3 is rotatably mounted on one side of the lower template 2. The support plate 3 can be rotatably mounted on the lower template 2 via a rotating shaft. Rotating the support plate 3 can achieve the formation of a forming groove at the bottom end of the forming through hole 21 by closing the support plate 3, or rotating the support plate 3 can achieve the support plate 3 being perpendicular to the lower template 2. The support plate 3 is located on one side of the lower template 2, which facilitates material feeding. The support mechanism 4 is installed between the support plate 3 and the frame 1.

[0041] Preferably, in order to further increase the workpiece, a telescopic component 11 is also included. The forming protrusion 6 is installed on the upper template 5 through the telescopic component 11. The telescopic component 11 is used to drive the forming protrusion 6 to rise and fall relative to the upper template 5, thereby further facilitating the adjustment of the distance between the forming protrusion 6 and the lower template 2 (i.e., the length of the forming protrusion 6 protruding relative to the upper template 5), which facilitates the cutting, correction and blanking of the workpiece. It should be noted that when cutting the edge, the distance of the forming protrusion 6 extending out of the lower template 2 is smaller when the workpiece is corrected by adjusting the telescopic component 11. When blanking, the distance of the forming protrusion 6 extending out of the lower template 2 is larger when the workpiece is corrected by adjusting the telescopic component 11.

[0042] It should be noted that the telescopic component 11 can be a telescopic component such as a cylinder or hydraulic cylinder in the prior art.

[0043] Preferably, the lower template 2 is provided with a heating element 12 for heating the lower template 2. When the upper template 5 and the lower template 2 are used to correct the workpiece, the heating element 12 heats the lower template 2 to perform the correction. Specifically, the heating element 12 can be an electric heating element 12 in the prior art. By heating the lower template 2, the workpiece inside the lower template 2 is heated through heat conduction, ensuring that the temperature of the workpiece is higher during correction than the temperature of the workpiece during cutting, thereby increasing the correction effect.

[0044] Preferably, the lower template 2 has a cooling channel 22. After heating and correcting one end for a period of time, the workpiece is cooled through the cooling channel 22 to further increase the correction effect. Preferably, coolant is introduced into the cooling channel 22. When the heating element 12 heats the workpiece for a certain period of time during the correction process, the heating element 12 is turned off to heat the lower template 2. Coolant is introduced into the cooling channel 22 to cool the lower template 2, thereby indirectly reducing the workpiece temperature and increasing the correction effect.

[0045] Preferably, the lower template 2 has an outlet 23 and an inlet 24 communicating with the cooling channel 22. The outlet 23 is located at the bottom of the lower template 2, and the inlet 24 is located on one side of the lower template 2. Preferably, the outlet 23 may also be located on one side of the lower template 2, or it may be located at the bottom of the lower template 2.

[0046] This allows for the circulation of coolant into the cooling channel 22 during the cooling process, ensuring effective cooling.

[0047] At the same time, when the material is being discharged, coolant is also introduced into the cooling channel 22, and then discharged through the outlet 23 and onto the guide plate 9. The coolant plays a lubricating role, which facilitates the discharge of the material.

[0048] Optionally, preferably, in some embodiments, the upper surface of the guide plate 9 is an inclined surface that gradually slopes upward from the side near the material outlet of the guide plate 9 to the side away from the material outlet of the guide plate 9, which facilitates material discharge;

[0049] In some preferred embodiments, the telescopic end of the lifting component is fixed with a base plate 13, the upper surface of the base plate 13 is inclined, and when the lifting component is telescopically extended to the lowest point, the upper surface of the base plate 13 and the upper surface of the guide plate 9 are in the same plane, which facilitates material discharge.

[0050] To ensure support for the support plate 3, a support block 14 is detachably installed on the top of the base plate 13. The lower surface of the support block 14 contacts the upper surface of the base plate 13, and the upper surface of the support block 14 contacts the bottom surface of the support plate 3.

[0051] To ensure the support contact effect, a limiting groove is opened on the base plate 13, and a limiting protrusion is provided at the bottom of the support block 14. The limiting protrusion matches the limiting groove, thereby preventing the support block 14 from sliding relative to the base plate 13.

[0052] Before trimming the edge, first install the support block 14 on the base plate 13, and then the lifting component rises up so that the support block 14 contacts and supports the support plate 3.

[0053] In some embodiments, the support plate 3 can be placed directly on the support block 14, or it can be...

[0054] After the calibration is completed, the lifting component moves the support plate 3 downward a certain distance and then removes the support block 14. Then, the support plate 3 is rotated so that it is perpendicular to the lower template 2. Then, the lifting component moves the bottom plate 13 upward a certain distance. When the material is dropped, the bottom plate 13 provides certain support for the workpiece. Then, the lifting component moves the workpiece downward to the discharge plate to realize the discharge. Preferably, the length of the bottom plate 13 is less than the length of the workpiece, which facilitates the dropping of the material.
