Abstract
Description
Technical Field
[0001] This utility model relates to the field of screw processing equipment technology, and in particular to a steel splinter accumulation alarm device for a screw forming machine. Background Technology
[0002] Screw forming machines generate sparks during screw production, which are discharged through the feeding track. However, screw production is typically a continuous operation, and the generation of sparks is also continuous. If not cleaned in time, the sparks will gradually accumulate in and around the feeding track. Because the machine has numerous oil pipes inside, when hot sparks accumulate for extended periods, the heat they carry is difficult to dissipate effectively. This heat can easily come into contact with the oil pipes, potentially causing a fire. This would severely disrupt normal production, threaten production safety, and could even destroy the forming machine itself, resulting in significant equipment and property damage, posing an extremely serious safety hazard. Utility Model Content
[0003] To address the aforementioned problems, this invention provides a steel spark accumulation alarm device for screw forming machines, which can monitor the accumulation of steel sparks. Therefore, the technical solution of this utility model is: a steel shavings accumulation alarm device for a screw forming machine, comprising a touch detection unit, a signal transmission unit, and a main control unit; the touch detection unit includes a touch detection sensor and a sensor mounting bracket, the sensor mounting bracket is fixed to the side of the steel shavings feeding track, the touch detection sensor is vertically mounted on the sensor mounting bracket, and the detection head of the touch detection sensor faces the steel shavings feeding track; the touch detection sensor can send the touch signal to the main control unit through the signal transmission unit, and the main control unit is used to control the machine to stop after receiving the touch signal.
[0004] Based on the above scheme and as a preferred embodiment of the above scheme: the sensor mounting bracket is fixed at a distance of 1 / 4 to 1 / 3 from the outlet of the steel flower unloading track.
[0005] Based on the above scheme and as a preferred embodiment of the above scheme, it also includes an alarm unit, which includes an audible and visual alarm. The main control unit controls the audible and visual alarm to work after receiving a touch signal.
[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the signal transmission unit is a wired transmission module, which realizes the signal transmission between the touch detection unit and the main control unit through wires.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the touch detection sensor is a lever-type limit switch.
[0008] Compared with the prior art, the beneficial effects of this utility model are: A contact detection unit is installed on the steel molten material feeding track. When the steel molten material accumulates and touches the detection head, the machine is immediately stopped. This avoids the risk of fire caused by the long-term accumulation of high-temperature steel molten material and contact with the machine's oil pipes, ensuring production safety and the integrity of equipment and property. Furthermore, the unit is located at 1 / 4 to 1 / 3 of the distance from the outlet, which can prevent frequent accidental shutdowns due to the detection position being too close, thus balancing safety and production continuity.
[0009] An alarm unit consisting of an added audible and visual alarm is installed. After the main control unit receives the signal, it simultaneously triggers the audible and visual alarm, which can more quickly remind operators to deal with the accumulated steel splinters in a timely manner and improve the efficiency of hazard handling.
[0010] The entire device has a simple structure and low cost, and can be used for the installation of new screw forming machines and the modification of old screw forming machines, with a wide range of applications. Attached Figure Description

[0013] In the description of this utility model, it should be noted that the directional terms such as "center", "horizontal (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.
[0014] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.
[0015] The steel shavings accumulation alarm device for a screw forming machine described in this embodiment includes a touch detection unit and a main control unit. The touch detection unit includes a touch detection sensor 1 and a sensor mounting bracket 2. The sensor mounting bracket 2 is fixed to the side of the steel shavings feeding track 3 and is located at a distance of 1 / 3 from the outlet of the steel shavings feeding track. The sensor mounting bracket 2 has a C-shaped structure and is fixedly installed on the outer side of the side wall of the steel shavings feeding track 3, with its front end extending into the steel shavings feeding track 3. The touch detection sensor 1 is vertically installed on the sensor mounting bracket 2, with the detection head 11 of the touch detection sensor 1 facing the steel shavings feeding track 3.
[0016] The touch detection sensor here can be a common limit switch available on the market, as long as it can trigger a signal when pushed by the piled-up steel flowers and transmit the signal to the main control unit through a wire. For example, a lever-type limit switch can be used, including a switch housing, a lever arm rotatably mounted on the switch housing, one end of the lever arm being placed inside the switch housing, and the other end extending out of the bottom of the switch housing and equipped with a roller; the side of the switch housing has a signal contact, and a spring is provided between the lever arm and the switch housing, the spring driving the lever arm away from the signal contact.
[0017] Initially, the upper end of the lever arm is far from the signal contact point, and the end with the roller is tilted towards the middle of the steel wire feeding track. When the steel wire accumulates, a force that overcomes the spring is applied to the lever arm, causing the lever arm to deflect and contact the signal contact point, thereby triggering the signal.
[0018] The main control unit is the PLC control system of the screw forming machine. After receiving the signal sent by the touch detection sensor, it controls the screw forming machine to stop. At the same time, it sends the signal to the audible and visual alarm. The audible and visual alarm can be built into the screw forming machine itself or a small audible and visual alarm 4 that is installed on the sensor mounting bracket. This allows users to quickly obtain the alarm location and clean up the accumulated steel scrap in time.
[0019] The shavings produced by the screw forming machine during continuous production are discharged along the feeding track. When the shavings accumulate to one-third of the way to the track outlet, they come into contact with the detection head of the lever-type limit switch and apply pressure, triggering the internal contacts of the limit switch and generating a touch signal. This signal is transmitted to the main control unit via the wired transmission module. Upon receiving the touch signal, the main control unit sends a command to the screw forming machine's operating system to immediately stop the machine. Simultaneously, it activates the audible and visual alarm to warn the operator that the shavings have accumulated to a critical position.
[0020] After the operator clears away the accumulated steel shavings, the lever-type limit switch resets, the touch signal is interrupted, the main control unit releases the shutdown command and turns off the audible and visual alarm, the device returns to the initial standby state, and the machine can restart production.
[0021] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
