Continuous centrifugal peening machine with input equipment of workpieces
The invention relates to a kind of the input equipment with work piece continuous centrifugal sand-blasting machine. Continuous centrifugal sand-blasting machine in accordance with a work piece by the input device input quantity and/or the flow velocity of the workpiece located in the sand is supplied to one or a plurality of centrifugal impeller device sand blasting quantity. The input work amount is input through the measurement of the weight of the work piece, is determined. In Patent EP-A1-004936 had introduced a kind for the workpiece can be evenly sand-blasting treatment as much as possible of such continuous centrifugal sand-blasting machine. However, practice proved that, when the change quantity of the work piece is supplied to the very large, even with the introduction of the measurement of the weight of the device is supplied to a work piece, is still not able to obtain the best processing of the sandblasting effect. The purpose of this invention is to make a kind mentioned at the outset herein centrifugal sand , the workpiece with improved measurement is supplied to the weight of the device, in order to as good as possible of the work piece even sand blasting treatment. According to the invention, this purpose is by claim 1 to achieve the characteristics of the part. That is, input device at least a portion of the length range of the part through the two ends of the length range of the pressure measuring equipment support. The structure of the invention forms the subsidiary rights of the outstanding advantages of described in the claims. The following is a description of the same: (1) continuous centrifugal sand-blasting machine, characterized in that in each of the ends are provided with two pressure measuring equipment. (2) continuous centrifugal sand-blasting machine, characterized in that pressure gauge pressure measuring device is made, through the amplifier connected in parallel to the centrifugal sand-blasting machine is connected to the electric adjusting device. (3) continuous centrifugal sand-blasting machine, characterized in that the input device is an endless belt, wherein the support of the belt in the at least a portion of the roller is supported through the pressure measuring equipment. Indicate in the attached drawing the invention, in order to explain and to below. The only indicated in the Figure is a station for the workpieces of different shapes and sizes, 3 continuous centrifugal sand-blasting machine are subjected to sandblasting treatment 1, sand-blasting machine 1 with a workpiece input device 2. Continuous centrifugal sand-blasting machine 1 has an inlet drum 4, an outlet roller 5 and a sand 6. The sand 6 is composed of endless belt 7 of the one belt groove. The upper part of the trough is provided with a centrifugal impeller 8. The two drum 4 and 5 and endless belt 7 by the transmission mechanism 10 to rotate, therefore the work piece 3 is turned, the roller and 4 and 5 and endless belt 7 of the blowtorch of 9 along the axial direction of the centrifugal jet delivery. Furthermore, the whole machine can be along the conveying direction of the work piece is inclined downwards. Since the arrow 11 is shown in the corresponding workpiece 3 continuously change the flow rate of. The emery the 6 different degree of filling, therefore, only through change or adjust the flow velocity of the workpiece and/or changing VW with the arrow 12 shown in the drilling of the corresponding centrifugal impeller 8 sand blasting quantity QSTM of the units can be generally achieve sand blasting quantity is a constant. Unit sand blasting quantity means is per unit of surface area of the workpiece (cm) and per unit time (seconds) sand blasting quantity of. The change of the flow rate by adjusting the drive motor, i.e. the motor 13 to the rotational speed of, the transmission mechanism 10 is provided with a speed measuring engine 14, it is used as a rotation speed adjusting circuit 19 the actual value of the sensor. In order to change the supply of sand blasting quantity , leading to the centrifugal impeller 8 sand blasting for into the conduit 15 is provided with a throttle valve 16, the throttle valve 16 with a servo drive mechanism such as servo motor 17 and a position signal generator such as potentiometer 18 is connected. The throttle valve 16 and servo motor 17 the implementation of the mechanism a, and potentiometer 18 is supplied to a regulation loop sand blasting quantity the 20 the actual value of the sensor. The input quantity of the work piece in the work piece by the input device 2 to determine the weight measuring device. Workpiece input device 2 is designed as a conveyor belt 21, supporting the upper belt 21a of the roller 22 is arranged in a part of the separate frame 23 on. A frame 23 of the two end 23a, 23b through the pressure measuring device 24 is supported on the base 25 the upper. Pressure measuring device 24 can produce the electrical signal is made of the manometer, normally in 23a, 23b is arranged on one end of each of the two manometer 24, connected in parallel through the amplifier 26 with a continuous centrifugal sand-blasting machine electric adjusting device 27 associated. Manometer 24 analog pad signal as a workpiece 3 measured value of the input quantity, input and converts electric adjusting device 27 to in. The electric adjusting device 27 is used as rated value of the output signal of the input one or two adjustment loop 20 and 21 to in. Because of the work piece the length range of the input device of the two ends of the part 23a, 23b is set manometer 24, therefore, can be quite accurately measure the input quantity of the work piece. The conveyor belt 21 under the condition of a relatively short, the two ends of the belt as a whole through the manometer support on the base. Measuring device is the length of the region, should be based on the input speed in the 1 to 3 meters to choose between, in order to ensure accurate measuring result. The measuring and the adjusting circuit 19, 20 for the actuating mechanism between the actual amendments, is provided with a adjustable time assigns the meter , it takes into consideration from the measuring device for the distance between the inverted sand-blasting treatment and the input speed of the work piece. Can also be used other transport device such as a roller as the input equipment of the work piece. Continuous centrifugal sand-blasting machine can also be designed into the drum-type blasting machine, with a closed, rotatable, as a drum of the sand blasting; or with a swinging, in a region of an opening on the top, as a drum of the sand blasting. The patent refers to the field of 'abrasive or related blasting with particulate material'. Input the weight of the work piece (3) of the continuous centrifugal sandblast nozzle (1) for measurement, convey it on the framework (23) that a part with roller (22) of (21a) is disclosed at and separated on supporting, both ends (23a,23b) of the framework (23) are supported on base (25) through the manometer (24). The electric adjusting device that the manometer (24) which produces telecommunication number passes the amplifier (26) and continuous centrifugal sandblast nozzle (1) is associative. After measuring the work piece amount of input, change the flow velocity of the work piece and/or sand blast amount supplied to the centrifugal wheel (8) by changing the rotational speed of cylinder, carry on homogeneous grit blasting to the work piece in order to reach. 1, continuous centrifugal sand-blasting machine in accordance with a work piece by the input device input quantity and/or the flow velocity of the workpiece located in the sand is supplied to one or a plurality of centrifugal impeller device sand blasting quantity , the input number of works by measuring input is used to determine the weight of the work piece, characterized in that input device (2) at least a portion of length through the range of the length range of the two ends of the part (23a, 23b) to the pressure device (24) supported. 2, the continuous centrifugal sand-blasting machine according to Claim 1, characterized in that in each end (23a, 23b) is provided with two pressure measuring device (24). 3, the continuous centrifugal sand-blasting machine according to Claim 1 or 2, characterized in that pressure measuring device (24) pressure gauge is made, through the amplifier connected in parallel to (26) and the centrifugal blasting machine electrical adjusting device (27) is connected. 4, -3 one of the continuous centrifugal sand-blasting machine according to Claim 1, characterized in that input device (2) is an endless belt (21), wherein the support, the upper belt (21a) of the roller (22) is of at least a part of the pressure measuring device (24) supported.
