Description

A positioning and alarm mechanism suitable for multi-station continuous forging Technical Field

[0001] This invention relates to a positioning and alarm mechanism suitable for multi-station continuous forging. Background Technology

[0002] In the production of safety locking seats, single-station or multi-station continuous forging presses are commonly used. Due to rising labor costs and large order volumes, many companies adopt automated robotic arms for clamping and handling. This necessitates accurate positioning when products are moved to the next process, and the ability to immediately alarm and stop when the mold is abnormally damaged. Currently, the traditional processing method relies on the precision of the robotic arm and reduced forging cycle time to ensure stable positioning. The alarm mechanism uses whether the grippers can hold the product and whether the equipment is overloaded as alarm conditions. However, in actual production, even precise positioning by the robotic arm can lead to instability, and the reduced cycle time significantly impacts production efficiency. If the product being produced is a deep-hole or irregularly shaped part, a damaged mold left in the irregular hole of the forging will not be detected by the alarm mechanism on the grippers. If this damage is not detected in time and the product flows to the next process, it can cause continuous damage to subsequent molds.

[0003] For products with high positioning requirements, processing speed is reduced to ensure stable positioning. For products with easily damaged molds, manual visual inspection is used. This means that products that could be continuously forged at multiple stations on a single machine must be produced individually on multiple machines. Furthermore, mold damage cannot be detected in time, leading to batch damage of both molds and products. While some alarm and positioning mechanisms exist on the market, their versatility is limited, and these structures are isolated and cannot be integrated into a complete system. Therefore, the equipment needs a safe and efficient mechanism that integrates positioning and alarm functions. Summary of the Invention

[0004] To address the issue that positioning and alarm mechanisms in multi-station continuous forging are used independently and lack versatility, this invention provides a positioning and alarm mechanism suitable for multi-station continuous forging. This is achieved by adding a complete set of auxiliary positioning and alarm mechanisms between each die frame. This mechanism includes positioning points and alarm detection points. The alarm detection points are contact-type; that is, a contact-type alarm mechanism is added at the corresponding position of the vulnerable die. If there is a broken die or product in the irregular hole, the gripper places the product into the positioning seat, and the probe in the alarm structure will touch the damaged part, triggering the equipment alarm and automatically stopping.

[0005] The positioning and alarm mechanism applicable to multi-station continuous forging according to the present invention includes a positioning seat, a positioning core rod, a probe rod, a limiting component, a spring, and a sensor. The positioning seat has a first stepped hole formed by a first large hole, a first stepped surface, and a first small hole connected from its upper surface downwards; the first stepped hole is a blind hole. The lower end of the positioning core rod is installed on the inner bottom surface of the first small hole, and the top end of the positioning core rod is higher than the first stepped surface. A second stepped hole formed by a second large hole, a second stepped surface, and a second small hole connected from its upper surface downwards is formed on the first stepped surface; the second stepped hole is a through hole. The spring is located in the second large hole above the second stepped hole, and its lower end is supported by the second stepped surface. The sensor is installed below the second stepped hole. In the second small hole; the probe rod has a convex ring around its circumference, dividing the probe rod into an upper section and a lower section. The diameter of the convex ring is smaller than the diameter of the second large hole but larger than the diameter of the second small hole, and the diameter of the convex ring is larger than the diameter of the spring hole. The diameter of the lower section of the probe rod is smaller than the diameters of the spring hole and the second small hole. The lower section of the probe rod passes through the spring hole from top to bottom and extends into the second small hole. A limiting member is installed on the first step surface and limits the range of vertical movement of the convex ring to below the limiting member. The top of the limiting member is lower than the top of the positioning core rod. When a defective product is placed in the first step hole, it is positioned by the positioning core rod. At the same time, the defective product will squeeze the top of the upper section of the probe rod, causing the probe rod to move down and touch the sensor, triggering the sensor alarm.

[0006] For easy installation, the positioning base has mounting holes for mounting onto external equipment.

[0007] To facilitate product positioning, the positioning core rod is hexagonal splined. The positioning core rod can be fixed to the bottom surface inside the first small hole, or it can be threaded to facilitate adjustment of the positioning core rod's height.

[0008] To facilitate the adjustment of the bolt height and thus the probe height, a bolt is used as the limiting component. When the bolt is in the limiting position, the lower surface of the bolt head abuts against the upper surface of the probe protrusion ring.

[0009] To facilitate adjustment of the sensor's position in the second small hole, the sensor is threadedly connected to the second small hole.

[0010] Beneficial Effects: The positioning and alarm mechanism of this invention can position products via a positioning core rod. When a defective product is positioned, it will press against the probe rod, causing the probe rod to move down and touch the sensor, triggering an alarm. Qualified products will not touch the probe rod. This invention is suitable for multi-station continuous forging processes, providing precise product positioning and alarms. It has a compact structure and can be modified from existing equipment without major adjustments to the original structure. It is highly practical and avoids batch damage to molds caused by the inability to quickly identify abnormal mold damage during forging, as well as the need to reduce the equipment's cycle time to achieve precise positioning. During continuous forging, if abnormal damage to the die occurs, this mechanism can quickly identify the damage point and immediately stop the equipment, avoiding the risk of continuous damage to subsequent dies and products. This saves debugging costs, improves the accuracy of automated production, and is easy to promote in batches. The positioning seat has mounting holes for easy installation on external equipment; the positioning core rod is a hexagonal spline for easy product positioning; the limit element is a bolt for easy adjustment of the bolt height, thereby adjusting the probe height; and the sensor's position in the second small hole is easily adjusted by a threaded connection between the sensor and the second small hole.

Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, but the present invention is not limited to the embodiments.

[0013] As shown in Figures 1-3, the present invention is a positioning and alarm mechanism suitable for multi-station continuous forging, including a positioning seat 1, a positioning core rod 2, a probe rod 3, a limiting component 4, a spring 5, and a sensor 6.

[0014] The positioning seat 1 is provided with a first stepped hole formed by connecting a first large hole, a first stepped surface 11 and a first small hole from the top surface downwards. The first stepped hole is a blind hole. The specific hole shape of the first large hole can be set according to the shape of the product. The positioning seat 1 is provided with a mounting hole 12 and equipped with screws for mounting to external equipment.

[0015] The aforementioned positioning core rod 2 is a hexagonal spline, with its lower end welded to the inner bottom surface of the first small hole, and its top end higher than the first stepped surface 11. A second stepped hole, formed by connecting the second large hole, the second stepped surface 13, and the second small hole, is formed on the first stepped surface 11 from the top surface downwards. The second stepped hole is a through hole. The aforementioned spring 5 is located in the second large hole above the second stepped hole, with its lower end supported by the second stepped surface 13. The sensor 6 is screwed into the second small hole from the end furthest from the second large hole below the second stepped hole.

[0016] The probe rod 3 has a convex ring 31 around its circumference, which divides the probe rod 3 into an upper section 32 and a lower section 33. The diameter of the convex ring 31 is smaller than the diameter of the second large hole and larger than the diameter of the second small hole. The diameter of the convex ring 31 is larger than the diameter of the spring hole. The diameter of the lower section 33 of the probe rod 3 is smaller than the diameter of the spring hole and the second small hole. The lower section 33 of the probe rod 3 passes through the spring hole from top to bottom and extends into the second small hole.

[0017] The limiting component 4 is a bolt, threaded onto the first stepped surface 11, limiting the vertical movement of the convex ring 31 to below the bolt head. That is, when the bolt is in the limiting position, the lower surface of the bolt head abuts against the upper surface of the convex ring 31 of the probe rod 3. The top of the bolt is lower than the top of the positioning core rod 2, and the top of the upper section 32 of the probe rod 3 is higher than the top of the positioning core rod 2 and lower than the upper surface of the positioning seat 1.

[0018] The height of the positioning core rod 2, the length of the upper section rod 32 and the lower section rod 33 of the probe rod 3, the thickness of the convex ring 31, and the screwing depth of the sensor 6 in the second small hole can be set according to the specific situation. However, it is necessary to ensure that the bottom end of the product does not touch the probe rod 3 after the qualified product is positioned, so that the equipment can operate normally. However, after the unqualified product is positioned, the bottom end of the product will squeeze the probe rod 3.

[0019] When a defective product is placed into the first-step hole, it is positioned by the positioning core rod 2. Simultaneously, the defective product presses against the top of the upper section 32 of the probe rod 3, causing the probe rod 3 to move downwards, compressing the spring 5 and touching the sensor 6, triggering an alarm and stopping the equipment. If the foreign object broken off from the inner hole of the defective product is too long or the product is completely unformed, the probe rod 3 will be pressed down, but due to the presence of the spring 5, the entire sensor 6 will not be damaged. After the defective product is removed, the probe rod 3 moves upwards under the elastic force of the spring 5 until the head of the bolt abuts against the convex ring 31.

[0020] Unless otherwise specified, all technologies mentioned above refer to existing technologies.

[0021] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification.
