Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a stamping conveying apparatus, which includes a base 1, a stamping platform 2, a connecting rod 6, a conveying platform 4, a support 7, a first conveying device 3, and a second conveying device 5.

Referring to fig. 1 to 4, a stamping platform 2 for placing a material is fixedly mounted on a base 1 to ensure that the material can be stamped stably. The stamping device is arranged above the stamping platform 2, and a driving device for automatically driving the stamping device is arranged on the side surface of the stamping platform 2 and is electrically connected with the stamping device. The driving device comprises a driving motor for driving the stamping device to ascend or descend and a first main control machine for setting the time interval of opening or closing of the driving motor, and the driving motor is electrically connected with the stamping device and the first main control machine. The driving device also comprises a second main control machine used for setting the rising or falling maintaining time of the punching device, and the punching device is electrically connected with the second main control machine. According to the invention, the driving device automatically drives the stamping device to stamp the material, the control by manpower is not needed, and only the driving device is needed to be started, so that the intelligent automatic production can be realized, the manpower can be saved, and the production efficiency can be improved.

Referring to fig. 1 to 4, the transportation platform 4 is installed at one side of the stamping platform 2 and is juxtaposed to the stamping platform 2. The stamping platform 2 is provided with a first transmission device 3, the transportation platform 4 is provided with a second transmission device 5, and the transportation surfaces of the two transmission devices are on the same horizontal plane.

Referring to fig. 1 to 4, two brackets 7 are respectively mounted on the stamping platform 2 and the transporting platform 4. The first transfer device 3 and the second transfer device 5 are mounted on two supports 7, respectively.

Referring to fig. 1 to 4, the conveyor is classified according to the presence or absence of a pulling element, and the conveyor with the pulling element is structurally characterized in that the material to be conveyed is contained in a carrier connected to the pulling element or directly on the pulling element, such as a conveyor belt. The traction elements are connected end to end around the rollers or sprockets to form a closed loop comprising a loaded branch carrying material and an unloaded branch not carrying material, and the material is conveyed by the continuous movement of the traction elements. Such transmission devices are of various types, and mainly include belt conveyors, plate conveyors, trolley conveyors, escalators, moving walks, scraper conveyors, buried scraper conveyors, bucket elevators, overhead conveyors, aerial cableways, and the like. The structure and composition of the transmission device without the traction piece are different, and the working components for conveying materials are also different. The structural characteristics are as follows: the material is conveyed forward by means of a rotary or reciprocating movement of the working member or by means of a flow of a medium in the pipe. For example, the working member of a roller conveyor is a series of rollers that rotate to convey material. The working member of the screw conveyor is a screw which rotates in the trough to push the material along the trough. The working member of the vibrating conveyor is a chute which reciprocates to convey materials and the like placed therein. In the embodiment, a belt conveyor can be selected as a conveying device to convey the processed automobile parts. A belt conveyor is a friction-driven machine that transports material in a continuous manner. The material conveying device can form a material conveying flow path from an initial feeding point to a final discharging point on a certain conveying line. The conveying device can be used for conveying both broken materials and finished articles, such as the automobile parts. The belt conveyor can not only carry out pure material conveying, but also match with the requirements of the technological process in the production flow of each industrial enterprise to form a rhythmic line production conveying line. The belt conveyor is widely used in various industrial enterprises in modernization.

Referring to fig. 1 to 4, the conveying device includes a conveying driving device, a roller 13, a carrying member, a tensioning device, and a direction changing device. The transmission driving device of the belt conveyor adopted in the embodiment comprises a motor, a reducer, a coupling or a fluid coupling, a transmission roller and the like. If the transmission route has an inclined section, the belt conveyor is also provided with a brake or a backstop according to the requirement. The transmission driving device is used for transmitting traction force to the conveying belt by the transmission roller through friction so as to move the conveying belt and convey goods. The traction force transmitted by the transmission roller can change along with different transport amounts and transport distances, so that the corresponding belt conveyor can adopt single roller drive, double roller drive and multi-roller drive according to the different required traction forces. In this embodiment, two ends of each belt conveyor are respectively provided with a transmission roller, two ends of a transmission roller shaft are respectively arranged at two sides of the corresponding support 7, each transmission roller can be provided with one or two motors, and the tail end of the transmission roller shaft is connected with the motor by a coupler.

Referring to fig. 1 to 4, the driving motor is generally a Y-series cage motor, which has the advantages of small size, low cost, reliable operation, and easy implementation of automatic control. When the power is lower (less than or equal to 37kW), the direct drive can be realized through the elastic coupling. When the power is larger (45-315kW), a hydraulic coupler can be matched, so that the starting is more stable. Under the condition of high power (220-800kW), a winding motor can be adopted, which is convenient to regulate and control, so that the long-distance belt conveyor is stably started, and the problem of power balance of multi-roller drive is solved.

Referring to fig. 1 to 4, the reducer of the belt conveyor may be implemented by a cylindrical gear transmission, and may be implemented by a conical gear transmission in order to reduce the transverse dimension of the conveyor transmission driving device.

Referring also to fig. 1-4, the drive roller transfers traction by friction between its surface and the conveyor belt. The transmission roller comprises a smooth surface and a rubber surface, wherein the rubber surface comprises a flat rubber surface, a herringbone pattern rubber surface (suitable for unidirectional operation), a diamond pattern rubber surface (suitable for bidirectional operation) and the like. The friction coefficient can be increased by adopting the rubber surface, particularly the patterned rubber surface, and the patterned rubber surface also has a certain effect on preventing the conveying belt from deviating. Under the conditions of low power and low environmental humidity, a smooth surface roller can be adopted, and when the environment is humid, the power is high, and the roller is easy to slip, a rubber surface roller can be adopted.

Referring to fig. 1 to 4, two sides of the carrier rollers 13 are mounted on the bracket 7 and are uniformly distributed between two transmission rollers of each conveyor. The carrier roller 13 can be a groove carrier roller, a flat carrier roller, a centering carrier roller and a buffer carrier roller. The groove-shaped carrier roller (consisting of 2-5 rollers) supports the bearing branch and is used for conveying bulk materials. The aligning carrier roller is used for adjusting the transverse position of the belt and avoiding deviation. The impact to the material can effectively be reduced to the impact idler that this embodiment adopted.

Referring also to fig. 1 to 4, a carrier member, such as a conveyor belt 12, is mounted on two drive rollers 11 and a plurality of support rollers 13. The conveyor belt 12 is wound around the transmission roller 11, and the transmission roller 11 cannot be too small in diameter because of fatigue damage caused by bending. The diameter specification of the transmission roller 11 can be 500 mm, 630 mm, 800 mm, 1000mm and the like. The conveyor belt 12 is commonly used with both rubber belts and plastic belts. The rubber belt is suitable for working environment at the temperature of-15-40 ℃. The temperature of the material does not exceed 50 ℃. The inclination angle of the upward conveying of the granular materials is 12-24 degrees. Patterned rubber belts are available for large dip delivery. The plastic belt has the advantages of oil resistance, acid resistance, alkali resistance and the like, but has poor weather adaptability and is easy to slip and age.

Referring to fig. 1 to 4, the tensioner is used to maintain the initial tension of the belt 12 necessary to prevent slipping on the drive roller 11 and to ensure that the sag of the belt 12 between the two rollers 13 is within a predetermined range. The tensioning device can be selected from a spiral type, a trolley weight type or a vertical weight type. The helical tensioner utilizes a manually rotated screw to adjust the tension of the conveyor belt 12. The tension device is simple and compact in structure, but the tension force is not easy to master, and the tension force cannot be kept constant in the working process. The trolley weight type tensioning device has large overall dimension, large occupied area and large mass, and is suitable for a conveyor with larger length and power, in particular to an inclined conveyor. The vertical weight type tensioning device can utilize the space position under the conveyor frame and is arranged at the position where the tension of the lower branch is minimum, thereby reducing the weight. In the vertical weight type tensioning device in the embodiment, two ends of the conveying belt 12 respectively bypass two transmission rollers 11, then respectively bypass two direction-changing rollers 14 and one tensioning roller 15 and then are connected together end to end, and a weight 16 is connected to the lower part of the tensioning roller 15, so that the conveying belt 12 is ensured to be in a tensioning state.

Referring also to fig. 1-4, the direction-changing drums 14 may be used for 180 °, 90 °, or <45 ° directional changes of the conveyor belt 12. The size of the redirecting drum 14 can be 250 mm, 315 mm, 400 mm, 500 mm, 630 mm, 800 mm, 1000mm and the like, and the diameter of the redirecting drum can be matched with that of the transmission drum 11 when the size is selected. When the angle is changed to 180 degrees, the diameter of the gear wheel can be smaller than that of the transmission roller 11 by one step, and when the angle is changed to 90 degrees or 45 degrees, the diameter can be properly reduced by 1-2 steps along with the reduction of the change angle.

Referring to fig. 1 to 4, the stamping and transporting apparatus of the present invention further includes at least one connecting rod 6 rotatably connected to two sides of the stamping platform 2 and the transporting platform 4, respectively. One end of each connecting rod 6 is rotatably connected to one side of the stamping platform 2, and the other end of each connecting rod 6 is rotatably connected to the same side of the transportation platform 4 and the stamping platform 2. The transportation platform 4 can be folded and placed at the upper part of the stamping platform 2 through the rotation of the joint of the two connecting rods 6, so that the occupied space can be saved when the equipment is not used. A gap of 20-100mm is reserved between the stamping platform 2 and the transportation platform 4, so that the materials can be prevented from falling off, and the interference generated when the stamping platform 2 and the transportation platform 4 are folded can be avoided.

Referring to fig. 1 to 4, the counting device 17, for example, an infrared counter, includes a transmitting end and a receiving end, the transmitting end is installed on one side of the transportation platform 4, the receiving end is installed on the other side of the transportation platform 4, working surfaces of the transmitting end and the receiving end are both higher than the conveyor belt 12, and the working surfaces of the transmitting end and the receiving end are opposite to each other. When the materials are conveyed through the conveying belt, each material can shield the light of the transmitting end once through the infrared counter, the receiving end outputs a pulse signal to trigger a counting circuit, and the number of the passing materials is calculated according to the triggering times of the counting circuit.
