Description
Technical field
The utility model relates to a kind of forcing press backform device and adjusts checkout gear, belongs to forcing press control system detection technique field.
Background technology
When current punching machine is used for shallow drawing process, a general configuration pneumatic type backform device.And senior backform device is generally the stroke adjustable structure, and the stroke of backform device guiding mechanism is general limited and all leave certain surplus.Therefore the detection of bound position is very important in guiding mechanism, and this is directly connected to the top and touches the working range and the safety of device, once exceed adjusting range, touches the structure and the mould of device with damaging the top, causes unpredicted loss.Testing agency to the adjustment of backform device is generally mechanical transmission mechanism at present, touch the metal collision block that is installed on the guiding mechanism by band spring reset leverage, realize ejection lover when guiding mechanism is in the upper and lower limit position, the lever that ejects triggers the mechanical type microswitch, microswitch provides signal, and controller cuts out the driver of guiding mechanism.
There is complex structure usually in this type of transmission mechanism, and technology, construction cooperate requirement high, difficult in maintenance, the not high shortcoming of reliability.
Summary of the invention
The purpose of this utility model provides a kind of forcing press backform device and adjusts checkout gear, overcome testing agency's reason mechanical transmission mechanism formation that existing backform device is adjusted, there is complex structure, technology, construction cooperate requirement high, difficult in maintenance, the not high shortcoming of reliability, save traditional mechanical transmission mechanism by the utility model, implementation structure is simple, detects dependable performance, and is easy to maintenance.
The purpose of this utility model is achieved through the following technical solutions, a kind of forcing press backform device is adjusted checkout gear, comprise the fuel tank in the guiding mechanism, the adjusting nut that worm gear connects through key in the fuel tank, it is characterized in that described device is by the aluminum metal derby of the built-in permanent magnetic iron that is fixed on the adjusting nut outside and be fixed on the oil tank wall hollow aluminum bar construction of the built-in magnetic switch at two places up and down; Permanent magnetic iron in magnetic switch induction cross section and the aluminum metal derby has spacing on the horizontal linear position, the signal of telecommunication of magnetic switch is connected to the controller of forcing press.
Permanent magnetic iron in magnetic switch induction cross section and the aluminum metal derby is the 8-12 millimeter in the locational spacing of horizontal linear.
The hollow aluminium bar of the built-in magnetic switch that two places are fixed about the oil tank wall is corresponding with the upper and lower limit position of guiding mechanism stroke.
The aluminum metal derby position encapsulation process of built-in permanent magnetic iron.
The utility model is the improvement of existing forcing press backform device being adjusted the checkout gear process, by the aluminum metal derby of built-in permanent magnetic iron and the hollow aluminum bar construction of built-in magnetic switch, the utility model utilizes the widely used magnetic switch in market, detect the permanent magnetic iron that is installed on the guiding mechanism by Hall effect, in case permanent magnetic iron enters in the detection range of magnetic switch under the drive of guiding mechanism, magnetic switch will provide the signal of telecommunication at once to controller, to close the driver of guiding mechanism.The utility model can be save traditional mechanical transmission mechanism, and magnetic switch and permanent magnetic iron all belong to market ripe, and dependable performance is easy to maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model on being fixed in the backform device guiding mechanism;
Among the figure, 1 aluminum metal derby, 2 permanent magnetic irons, 3 hollow aluminium bars, 4 magnetic switch, 5 adjusting nuts, 6 fuel tanks.
The specific embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, the utility model is made of the aluminum metal derby 1 of built-in permanent magnetic iron 2 and the hollow aluminium bar 3 of two built-in magnetic switch 4; During use, aluminum metal derby 1 be fixed on backform device guiding mechanism worm gear through key connect adjusting nut 5 lateral surfaces on, worm gear in the guiding mechanism rotates and drives adjusting nut 5 rotations, adjusting screw(rod) is moved up and down, thereby change backform device stroke, permanent magnetic iron 2 should be embedded in the aluminum metal derby 1, and carries out encapsulation process, with avoid with adjust fuel tank 6 in materials such as oils contact.The hollow pole 3 of the aluminum of two built-in magnetic switch 4 is fixed on the wall of fuel tank 6, corresponding with the upper and lower limit position of guiding mechanism stroke, guarantee magnetic switch 4 induction sectional areas apart from the horizontal linear position of permanent magnetic iron 2 in the scope of magnetic switch 4, but need not contact, distance is usually in 10 millimeter, so the installation accuracy requirement is low.When guiding mechanism is worked, permanent magnetic iron 2 will be with the upper and lower motion of guiding mechanism, in case permanent magnetic iron 2 enters in the Hall effect sphere of action of magnetic switch 4, magnetic switch 4 will be triggered, thereby produce the signal of telecommunication to controller, controller will cut off guiding mechanism direction of motion driver this moment, send warning message simultaneously, guarantee that the backform device is in the working range of design, avoid exceeding design parameter and the hard damage that causes.The signal that while magnetic switch 4 provides can carry out two-way constraint with the stroke height measuring mechanism of guiding mechanism, both when magnetic switch 4 is in the bound position, the measurement numerical value of the stroke measurment mechanism of guiding mechanism also should be in upper and lower limit numerical value position, whether the stroke measurment mechanism that therefore can effectively differentiate guiding mechanism is in normal duty, simultaneously can oppositely differentiate magnetic switch 4 and whether be in normal duty, be in the normal range of operation to guarantee to push up the guiding mechanism of touching device.
The structure of this bound testing agency is very simple, does not have consumable accessory, works at ordinary times and need not safeguard.Permanent magnetic iron and magnetic switch are market ripe, and stable performance is cheap, install and use all very convenient.
