Wherein, the procedures of feeding, transferring and blanking can be carried out synchronously, or respectively, or step by step. The movable space is the space required by the movable assembly and the parts carried by the movable assembly to move between the stamping surfaces of the upper die and the lower die.
The specific stamping steps are as follows: initial (no load in the punch body), a loading procedure-a punching procedure-a loading and transfer procedure-a punching procedure-a loading, transfer and blanking procedure … a punching procedure-a transfer and blanking procedure-a punching procedure-a blanking procedure-an end (no load in the punch body).
Referring to fig. 4, as an option, in an embodiment, unlike the previous embodiment, the present embodiment uses the lower mold locking device to lock the part, and after the slide block moves upwards to expose the movable space in the punching area, the part is moved to the next punching position step by step or synchronously using 4 moving assemblies I31, and a lower mold is first emptied and then the part is placed and fixed according to the first-in-first-out principle, which will not be described in detail herein. Wherein the Z-axis height of the 4 moving assemblies I31 is not required to be as high as the slide ready state position. Of course, in the foregoing example, the operation is performed in advance at the edge of the punching area, and the upper die and the lower die of the same set of dies can be operated at the same time when the movable space is exposed, so that the operation time can be shortened.
As described above, n is a natural number of 2 or more, and the above description exemplifies the case where n is 3, and other cases such as n is 5 or 7, etc., can be understood in conjunction with the above description.
As an option, based on the foregoing example, in one example, m sets of molds are sequentially arranged on the worktable and the slide block from left to right to realize a complete set of processes of two parts, wherein m is greater than n; the two sets of part processes are arranged in front and back, namely, one part process is arranged in sequence and then the other part process is arranged in sequence, the part process far away from the feeding mechanism carries out feeding operation firstly, and the feeding operation moves up the slide block to enable the stamping area to just move to the stamping area when the stamping area is exposed out of the movable space. Therefore, the process distribution of two parts can be realized on a row of dies arranged in sequence under the condition that the working table surface has fewer processes and is excessive in vacancy, so that the spaces of the working table and the stamping surface of the sliding block are fully utilized.
As an option, based on the foregoing example, in an example, the apparatus is further configured with a sensor unit, the sensor unit includes a detection sensor and a counter, the detection sensor can be configured on the clamping component, or the front end of the moving component is installed beside the position of the clamping component, and the detection port of the detection sensor faces the position where the part is clamped. The detection sensor is used for detecting parts, such as a pressure sensor, and the parts force the pressure sensor to deform to output signals when the sucker adsorbs the parts; such as a proximity switch sensor (e.g., a photoelectric proximity switch, a capacitive proximity switch, or an inductive proximity switch), that detects the proximity of an object to output a signal. In combination with the processing center of the control system, the equipment detection process is as follows: responding to the clamping operation of the clamping assembly, starting the detection sensor to detect the part when sending a clamping instruction to the clamping assembly or delaying for a certain time (such as 1 or 3 seconds), receiving a detection signal fed back by the detection sensor, and then judging whether the part is detected according to the detection signal of the detection sensor.
In the same process flow, the part materials are gradually conveyed backwards to the position of the next process in sequence, the part materials are gradually detected by the detection sensor, and the whole in-place clamping conveying process can be monitored; and at the detection sensors at the adjacent positions, when the detection result of the detection sensor at the later position is different from the previous detection result of the detection sensor at the previous position, the falling of the part material or the failure of the detection sensor is judged, and the control equipment stops running.
When the detection sensor of the clamping assembly at the last position of the process flow detects a part and the detection sensors of other clamping assemblies do not detect the part, the detection sensor cannot detect the material, and no material exists, at the moment, the equipment stops operating after continuously executing the operation corresponding to the last clamping assembly, and then the stamping equipment stops.
When the detection sensor detects the parts, the accumulation counting operation is carried out so as to record the number of the parts clamped by the detection sensor. Of course, a counter can be adopted and can be arranged on the last clamping assembly or at the position of the blanking point, so that the number of the machined parts can be detected and recorded.
Of course, it is also possible to arrange a detection sensor at the feeding point for detecting whether the material is in place or not, so as to control the punching operation of the apparatus, perform the punching operation or stop the punching operation (or start or stop the punching apparatus). When the control system starts the stamping operation, if no material is detected (no material) at the feeding point, the subsequent stamping operation is not executed, and if the material is detected (material) at the feeding point, the subsequent stamping operation is executed; in the stamping process, if the material is not detected at the material loading point for a long time, if the material is not detected at the material loading point for 4 minutes under the premise that the whole stamping process of the material needs 2 minutes, the stamping operation is stopped if no material is judged, and the fault problem may be detected.
As mentioned above, the equipment can monitor whether materials or parts exist at each working procedure position by configuring the detection sensor, monitor the running condition of the equipment in real time, and timely find that the equipment has the conditions of no material and no load or falling of the materials and the like so as to timely control the equipment to stop running.
It is to be understood that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," and the like, when used in reference to a particular orientation or positional relationship, are used merely to facilitate describing the invention and to simplify the description.
The foregoing description is directed to the details of preferred and exemplary embodiments of the invention, and not to the limitations defined thereby, which are intended to cover all modifications and equivalents of the invention as may come within the spirit and scope of the invention.
