[0002] During the door frame processing, when the raw materials come out of the roller mill (tube drawing machine), the next step is to cut according to the size of the door frame. Traditional processing usually uses manual feeding of raw materials to the cutting machine, the length is guaranteed by the tooling, and the cutting machine is manually operated for cutting. After the cutting is completed, the cut pieces are fed to the next station. When the door frame size changes, the tooling needs to be adjusted, and the process is cumbersome. The whole process has the following problems: loading and unloading are completed manually, the labor intensity is high, and the efficiency is low; the cutting quality is determined by the skill level of the operator, and the product quality is uncontrollable. Some door frame manufacturers use mechanical processing methods, and the machine loads, cuts and unloads the materials. The raw materials are moved by the roller, and after positioning and stopping according to the size of the door frame, the cutting machine is controlled by the relay to complete the cutting, and then the raw materials are transported to the next station. Due to the use of static cutting, the roller needs to slow down to stop, wait and accelerate during the process, which is inefficient and affects the overall processing rhythm.

[0024] Embodiment 1

[0025] This embodiment provides a shearing control system for product processing, including:

[0026] A shearing control unit, a shearing shaft, a sensor unit and a chopping unit installed on the shearing shaft;

[0027] Among them, when the tracking shear control unit receives the size of the product to be processed, it calculates the target position of the sensor unit; and when the sensor unit moves to the target position and the tracking shear control unit detects the incoming material signal, it controls the tracking shear axis to chase the incoming material, and when it is detected that the tracking shear axis and the incoming material meet the chopping conditions, a chopping signal is sent to the chopping unit to control the chopping unit to complete the chopping of the incoming material.

[0028] The product processing tracking shear control system provided by this embodiment will be described in detail below with reference to the drawings. In this embodiment, the product processing tracking shear control system is described by taking a door frame as an example of a product to be processed.

[0029] See also Figure 1 , which is a schematic diagram showing the principle structure of a shearing control system for product processing in one embodiment. Figure 1 As shown, the shearing control system 1 for product processing includes a shearing control unit 11, a shearing shaft (not shown), a sensor unit 12 and a chopping unit 13 installed on the shearing shaft, a material measuring servo drive 14, a shearing servo drive 15 and a chopping hydraulic unit 16. In this embodiment, the sensor unit 12 is a laser sensor.

[0030] The speed encoder 10 is used to measure the incoming material speed v0.

[0031] The tracking shear control unit 11 is used to calculate the target position of the sensor unit when receiving the size of the door frame to be processed.

[0032] In this embodiment, the tracking shear control unit calculates the target position of the sensor unit by adding the size of the product to be processed and the zero position offset Δ of the sensor.

[0033] For example, the sizes of the door frame to be processed include 950 and 950, 2050 and 2050, and the target positions of the sensing units are 950+Δ and 2050+Δ.

[0034] When the laser sensor 12 is driven to the target position by the material measuring servo drive 14, the tracking shear control unit 11 detects whether the incoming material is in place. When the incoming material moves to the positioning position of the laser sensor 12, the laser sensor 12 is triggered to output an incoming material signal to the tracking shear control unit 11.

[0035] After receiving the incoming material signal, the shearing control unit 11 enters the chasing stage, controls the shearing shaft to chase the incoming material, and sends a shearing signal to the shearing unit after detecting that the shearing shaft and the incoming material meet the chopping conditions, so as to control the chopping unit to complete the chopping of the incoming material.

[0036] In this embodiment, the chopping conditions include:

[0037] The shearing speed of the shearing shaft is equal to the material incoming speed;

[0038] The chasing distance of the chasing shear axis is equal to the moving distance of the incoming material.

[0039] Specifically, the shearing control unit 11 monitors the shearing speed v1 of the shearing shaft, and determines whether the shearing speed v1 of the shearing shaft is equal to the incoming material speed v0; if the shearing speed v1 is equal to the incoming material speed v0, the chasing distance S1 of the shearing shaft and the moving distance S0 of the incoming material are calculated respectively to determine whether the two are the same; if so, it means that the shearing shaft and the incoming material meet the chopping condition; if not, it means that the shearing shaft and the incoming material do not meet the chopping condition; if the shearing speed v1 is not equal to the incoming material speed v0, the shearing speed v1 of the shearing shaft continues to be monitored.

[0040] See also Figure 2 , which shows the shearing curve diagram formed by the shearing axis during the shearing process. Among them, the material speed is v0, the shearing speed is v1, and the shearing acceleration and deceleration are both a (a is the set value). Figure 2 As shown, the chasing shear control unit 11 receives the door frame cutting size at time A, and the chasing shear control unit 11 controls the chasing shear axis to start chasing the incoming material movement, then entering the chasing stage, the time for the chasing shear axis to accelerate from 0 to v0 is t1, and the time for accelerating from v0 to v1 is t2, that is, the chasing shear axis first accelerates to time B, maintains a uniform speed v1 to time C (the time for maintaining a uniform speed v1 is t3), and then decelerates from v1 to time D, the chasing shear axis speed is consistent with the incoming material speed, and enters the synchronization stage; in the synchronous motion stage, the cutting device and the incoming material speed are consistent, and there is no relative motion.

[0041] Among them, the movement distance of the incoming material S0 = v0 × (t1 + t2 + t3 + t4);

[0042] Chasing distance of the shear axis

[0043] Among them, v0=at1, v1=v0+at2, at2=at4.

[0044] when Simplified to:

[0045] The shearing control unit 11 detects that the shearing shaft and the incoming material meet the chopping conditions, and sends a chopping signal to the chopping hydraulic unit 16. The chopping hydraulic unit 16 controls the chopping unit to complete the chopping of the incoming material, thereby achieving dynamic and precise cutting of the door frame without stopping.

[0046] After the cutting is completed, the shear control unit 11 controls the shear axis to return to the operation origin. Figure 2 The shearing control unit 11 controls the shearing axis to start decelerating at time E, decelerates to 0, then accelerates in the reverse direction to time F, and then decelerates to time G. The shearing axis returns to the operation origin, completing the current cycle shearing process and entering the next shearing cycle. The shearing control unit 11 receives different sizes of the product to be processed, recalculates the target position of the sensor unit, and adjusts the distance between the cutting unit 13 and the laser sensor 12 support, thereby realizing dynamic adjustment of the cutting size and realizing non-stop processing.

[0047] The shearing control system for product processing described in this embodiment improves the production mode of the cutting process in the existing product processing process, reduces labor costs, improves production efficiency and product quality, enhances product consistency, and realizes non-stop dynamic and precise cutting of the products to be processed.

In actual implementation, they can be fully or partially integrated into one physical entity, or they can be physically separated. And these units can all be implemented in the form of software called by processing elements, or they can all be implemented in the form of hardware, or some units can be implemented in the form of software called by processing elements, and some units can be implemented in the form of hardware. For example: the control unit can be a separately established processing element, or it can be integrated in a chip of the above device.

These units may be integrated together and implemented in the form of a system-on-a-chip (SOC).
