Description

Technical Field

[0001] This utility model relates to the technical field of metal open press equipment, and in particular to an open press for pressing titanium alloy. Background Technology

[0002] In the current processing of titanium alloy sheets, a jog press is often used to level the sheets. For example, document CN222403127U discloses a jog press conveying mechanism for titanium alloy sheets. This mechanism addresses the problems of time-consuming and labor-intensive manual handling of sheets, insufficient sheet fixation during processing, and low processing efficiency. The jog press conveying mechanism can better clamp the titanium alloy sheets, and the position of the sheets can be adjusted during clamping. It is convenient to use, and the cylinder is used to push the moving sheet, saving time and effort and facilitating the processing.

[0003] However, in actual use, the clamping assembly uses a manually rotated screw to push the clamping plate to fix the plate. This requires manual judgment of the spring compression to control the clamping force, which is cumbersome and inconsistent. For mass production, manual adjustment is time-consuming and labor-intensive, which contradicts the design goal of improving processing efficiency. Furthermore, when the moving plate is pushed for processing, loading and unloading need to be performed before and after processing, resulting in a gap period that inevitably affects processing efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an open press for pressing titanium alloys.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An open press for pressing titanium alloy includes an open press with a punch head for pressing titanium alloy. A feeding mechanism is located in front of the open press, including a motor and a rotary table. Three placement platforms arranged in a circular array are fixedly connected to the rotary table. The motor drives the rotary table to rotate, causing the three placement platforms to alternately move to below the punch head. Several evenly distributed clamping components are installed on the placement platforms to fix and clamp the titanium alloy sheet body, preventing it from shifting position during processing.

[0006] Furthermore, the clamping assembly includes a base, on which a slide, a support, and a hinge are fixedly connected respectively. A clamping rod is slidably disposed within the slide. An electric actuator is hingedly mounted on the inner side of the support. A toggle plate is hingedly mounted on the hinge. A lever is fixedly connected to the side of the toggle plate. The movable end of the electric actuator is hinged to the lever. A linkage plate is hinged between the toggle plate and the clamping rod.

[0007] Furthermore, a support platform is fixedly connected to the open press, the motor is fixedly installed inside the support platform, a worm gear is fixedly connected to the output shaft of the motor, a rotating shaft is rotatably connected to the support platform, a rotating table is fixedly connected to the top of the rotating shaft, and a worm wheel that meshes with the worm gear is fixedly sleeved on the rotating shaft.

[0008] Furthermore, the clamping end of the clamping rod is equipped with an elastic buffer pad, which is made of either polyurethane or nitrile rubber.

[0009] Furthermore, a self-lubricating bearing is embedded at the sliding engagement point between the clamping rod and the slide block, and the friction coefficient of the self-lubricating bearing is ≤0.05.

[0010] Furthermore, the top of the support platform is provided with an annular groove, and the bottom of the rotating platform is fixedly connected to a bracket corresponding to the placement platform, with rollers located in the annular groove rotatably connected to the bracket.

[0011] All electronic components and mechanical structures involved in this application must conform to the operating environment.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this application, the feeding mechanism adopts a motor-driven rotary table with three placement tables arranged in a circular array, which can form an alternating operation of the clamping area, pressing area and unloading area. When one placement table is pressing under the punch head, the other placement tables can simultaneously complete the loading or unloading, avoiding the problem that the traditional single-station processing cannot load or unload materials during pressing, and the loading and unloading cannot be pressed, thus improving the equipment utilization rate.

[0013] 2. In this application, the clamping assembly adopts a four-bar structure driven by an electric push rod. The electric push rod extends and retracts to drive the clamping rod to slide, thereby achieving automatic clamping or releasing, replacing the traditional manual operation. The clamping force can be precisely adjusted by the stroke of the electric push rod, saving time and effort in the adjustment process, further shortening the auxiliary processing time, and significantly improving the overall processing efficiency compared with the prior art.

Detailed Implementation

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] like Figure 1-5 As shown, this utility model provides an open press for pressing titanium alloys, including an open press 100. The open press 100 is equipped with a punch head 101 for pressing titanium alloys. A feeding mechanism 200 is provided in front of the open press 100. The feeding mechanism 200 includes a motor 201 and a rotary table 202. Three placement platforms 203 arranged in a circular array are fixedly connected to the rotary table 202. The motor 201 drives the rotary table 202 to rotate, causing the three placement platforms 203 to alternately rotate below the punch head 101. Several evenly distributed clamping components 300 are installed on the placement platforms 203. The clamping components 300 are used to fix and clamp the titanium alloy sheet body, which can prevent it from shifting its position during processing. It should be noted that the device can be controlled by a PLC controller and a corresponding program. This is prior art and will not be described in detail here.

[0019] In this embodiment, the clamping assembly 300 includes a base 301, on which a slide 302, a support 303, and a hinge 304 are fixedly connected respectively. A clamping rod 305 is slidably disposed in the slide 302. An electric push rod 306 is hingedly installed on the inner side of the support 303. A toggle plate 307 is hingedly installed on the hinge 304. A lever 308 is fixedly connected to the side of the toggle plate 307. The movable end of the electric push rod 306 is hinged to the lever 308. A linkage plate 309 is hinged between the toggle plate 307 and the clamping rod 305.

[0020] Specifically, the extension and retraction of the electric actuator 306 can move the lever 308 and the actuating plate 307. The movement of the actuating plate 307 pulls the clamping rod 305 to slide within the slide block 302 via the linkage plate 309. When the electric actuator 306 shortens, the clamping rod 305 moves inward to tighten the plate. When the electric actuator 306 extends, the clamping rod 305 releases the plate. The electric actuator 306 provides a stable driving force, replacing traditional manual clamping. The clamping force can be precisely adjusted through the stroke of the electric actuator 306. Compared with existing technologies, this adjustment is time-saving and labor-saving, improving processing efficiency. It should be noted that a miniature pressure sensor can be added to the clamping rod 305, or the electric actuator 306 control system can integrate force feedback closed-loop adjustment to monitor the clamping force in real time. This is existing technology and will not be elaborated further here.

[0021] In this embodiment, a support platform 204 is fixedly connected to the open press 100, a motor 201 is fixedly installed inside the support platform 204, a worm gear 205 is fixedly connected to the output shaft of the motor 201, a rotating shaft 206 is rotatably connected to the support platform 204, a rotating table 202 is fixedly connected to the top of the rotating shaft 206, and a worm wheel 207 that meshes with the worm gear 205 is fixedly sleeved on the rotating shaft 206.

[0022] Specifically, the output shaft of motor 201 is connected to worm gear 205, which meshes with worm wheel 207 on rotating shaft 206, driving rotary table 202 to rotate. The transmission ratio of worm gear 205 and worm wheel 207 is stable, with significant speed reduction and torque increase effects. Motor 201 can drive rotary table 202 to rotate smoothly at low speed, avoiding positioning deviation of placement table 203 caused by inertial impact. Furthermore, the transmission of worm gear 205 and worm wheel 207 has self-locking characteristics, which can prevent rotary table 202 from reversing due to reaction force during stamping, ensuring that placement table 203 remains stationary in the processing position and improving operational safety. It should be noted that an angle encoder is added to the transmission system of worm gear 205 and worm wheel 207 to provide real-time feedback on the rotational position of rotary table 202, forming a closed-loop control with motor 201, and clarifying the angular positioning accuracy when rotary table 202 drives placement table 203 to switch. This is existing technology and will not be elaborated on further here.

[0023] In this embodiment, the clamping end of the clamping rod 305 is equipped with an elastic buffer pad 310. The elastic buffer pad 310 is made of either polyurethane or nitrile rubber and has anti-slip texture on its surface.

[0024] Specifically, when the clamping rod 305 clamps the plate, the elastic buffer pad 310 is compressed and undergoes elastic deformation, increasing the contact area and friction with the plate, thus avoiding clamping marks or pressure damage; and the anti-slip texture increases the coefficient of friction, preventing the plate from undergoing slight displacement due to vibration during stamping.

[0025] In this embodiment, a self-lubricating bearing 311 is embedded at the sliding engagement point between the clamping rod 305 and the slide block 302, and the friction coefficient of the self-lubricating bearing 311 is ≤0.05.

[0026] Specifically, a self-lubricating bearing 311 is embedded at the sliding engagement between the clamping rod 305 and the slide block 302. The self-lubricating bearing 311 contains solid lubricant, which is automatically transferred to the friction surface when the clamping rod 305 slides back and forth to form a lubricating film, thus avoiding clamping failure caused by the clamping rod 305 getting stuck, and also has a long service life.

[0027] In this embodiment, the top of the support platform 204 is provided with an annular groove 208, and the bottom of the rotating platform 202 is fixedly connected with a bracket 209 corresponding to the placement platform 203. A roller 210 located in the annular groove 208 is rotatably connected to the bracket 209.

[0028] Specifically, the rollers 210 on the support 209 at the bottom of the rotary table 202 roll along the annular groove 208 to ensure rotational concentricity. This limits the radial displacement of the rotary table 202 caused by centrifugal force or uneven load, ensuring that the placement platform 203 always maintains coaxiality with the stamping head 101 during rotation.

[0029] All electronic components and mechanical structures involved in this application must conform to the operating environment.

[0030] How to use and how to work this device: First, the titanium alloy to be processed is placed on the placement table 203. The extension and retraction of the electric actuator 306 can drive the lever 308 and the actuating plate 307. The movement of the actuating plate 307 pulls the clamping rod 305 to slide in the slide block 302 and clamp the plate through the linkage plate 309. The electric actuator 306 provides a stable driving force, replacing the traditional manual clamping. The clamping force can be precisely adjusted by the stroke of the electric actuator 306. Compared with the existing technology, the adjustment is time-saving and labor-saving, and improves the processing efficiency. Subsequently, the worm gear 205 is driven to rotate by the motor 201. The worm gear 205 cooperates with the worm wheel 207 to rotate the shaft 206. The shaft 206 drives the rotary table 202 to move the placement table 203 carrying titanium alloy to the bottom of the stamping head 101 for pressing. Meanwhile, titanium alloy can continue to be clamped on the blank placement table 203. This makes the three placement tables 203 form a clamping area, a pressing area, and a unloading area, ensuring that the loading and unloading are not delayed during the pressing process, avoiding the situation where other operations cannot be performed during the pressing process, and improving processing efficiency.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
