Description

Technical Field

[0001] The utility model relates to the technical field of stamping, in particular to a stamping and cutting device convenient for material taking. Background Technique

[0002] Stamping is a processing method that applies external force to plates, strips, tubes, profiles, etc. through a press and a die, so that they undergo plastic deformation or separation, thereby obtaining workpieces with the required shape and size, also known as stamped parts. Stamping and forging both belong to plastic processing and are collectively called forging and pressing.

[0003] Stamping processing mainly uses hot-rolled and cold-rolled steel plates and steel strips as raw materials. 60% to 70% of the world's steel is sheet metal, and most of it is made into finished products through stamping processing. The body, chassis, fuel tank, radiator fins of automobiles, the steam drum of boilers, the shells of containers, the silicon steel sheets of the cores of motors and electrical appliances, etc. are all processed by stamping. A large number of stamped parts are also widely used in products such as instruments, household appliances, bicycles, office machinery, and daily utensils.

[0004] However, in the actual stamping process of the above-mentioned press, some stamped parts are located between the upper and lower dies after processing, which is not convenient for directly manually taking out the finished products. The operator needs to reach into a narrow space to take them out, and there is a risk of being pinched or collided; in view of this, we propose a stamping and cutting device convenient for material taking. Content of the Utility Model

[0005] The purpose of the utility model is to provide a stamping and cutting device convenient for material taking to solve the problems raised in the above background technique.

[0009] A lower pressure rod, the side wall of the transmission shaft is fixedly connected to the cross bar, and one end of the cross bar away from the transmission shaft is fixedly connected to the lower pressure rod;

[0010] A limiting rod, the bottom end surface of the operating table is fixedly connected with a mounting sleeve, the inner wall of the mounting sleeve is fixedly connected with a rubber strip, the inner bottom of the mounting sleeve is fixedly connected with a spring, one end of the spring away from the inner bottom of the mounting sleeve is fixedly connected to the limiting rod, and the limiting rod is sleeved with the operating table.

[0011] Preferably, a convex strip is fixedly connected to the top end surface of the operating table.

[0012] Preferably, there are two groups of elastic members, and the two groups of elastic members are respectively arranged at two ends of the inner wall of the feeding clamp.

[0013] Preferably, the bottom of the storage barrel is suspended, the height of the feeding clamp is smaller than the height of the suspended bottom of the storage barrel, and the feeding clamp passes through the bottom of the storage barrel to bring out the steel plate in the storage barrel.

[0014] Preferably, the axis of the limiting rod coincides with that of the pressing rod, the diameter of the limiting rod is equal to the diameter of the pressing rod, and the downward movement of the pressing rod pushes the limiting rod to move downward.

[0015] Preferably, the rubber strip abuts against the limiting rod, and the rubber strip increases the friction between the limiting rod and the mounting sleeve, thereby adding damping to the movement of the rubber strip.

[0016] Compared with the prior art, the utility model provides a punching and cutting device that is convenient for material collection and has the following beneficial effects:

[0017] 1. The punching and cutting device, which is convenient for material taking, is provided with a feed clamp, an elastic part, a lower pressure rod, a limit rod and a stop block. After punching and cutting, the motor drives the feed clamp to pass above the limit rod to push the punched part out from between the upper die and the lower die, which is convenient for the operator to take and improves the safety of the operator. Before punching, the feed clamp rotates to move the steel plate to the bottom of the upper die, and the stop block is blocked by the limit rod, so that the steel plate is aligned with the upper die and the lower die, thereby improving the accuracy of punching and cutting.

[0018] 2. The stamping and cutting device facilitating material taking is provided with ridges. During the process of the feeding clamp gripping the steel plate, the ridges resist the steel plate, making it easier for the steel plate to enter between the two elastic members. At the same time, since the side surface of the ridge is arc-shaped, it will not affect the movement of the feeding clamp with the steel plate, improving the operation accuracy and efficiency, ensuring that the steel plate can be accurately moved to the stamping position after being clamped, and reducing errors or wastes that may be caused by inaccurate gripping.

[0024] In an embodiment of the present utility model, a mounting frame 7 is fixedly connected to the top end face of the operating table 1, a storage cylinder 8 is fixedly connected to the end of the mounting frame 7 away from the operating table 1, the bottom of the storage cylinder 8 is arranged in a suspended manner, the height of the feeding clamp 12 is less than the height of the bottom of the storage cylinder 8 in a suspended state, and the feeding clamp 12 takes out the steel plate in the storage cylinder 8 through the bottom of the storage cylinder 8;

[0025] Feeding clamp 12, the bottom end surface of the operating table 1 is fixedly connected with a motor 9, the output end of the motor 9 is fixedly connected with a rotating shaft 10, the rotating shaft 10 passes through the bottom end surface of the operating table 1, and the rotating shaft 10 is fixedly connected to a connecting arm 11, the end of the connecting arm 11 away from the rotating shaft 10 is fixedly connected with the feeding clamp 12, the inner wall of the feeding clamp 12 is fixedly connected with an elastic member 13, the number of the elastic members 13 is provided in two groups, the two groups of elastic members 13 are respectively provided at the two ends of the inner wall of the feeding clamp 12, and the end of the feeding clamp 12 away from the connecting arm 11 is fixedly connected to a stopper 14;

[0026] A lower pressure rod 16, a side wall of the transmission shaft 4 is fixedly connected to the cross bar 15, and an end of the cross bar 15 away from the transmission shaft 4 is fixedly connected to the lower pressure rod 16;

[0027] A limiting rod 19, the bottom end surface of the operating table 1 is fixedly connected with a mounting sleeve 17, the inner wall of the mounting sleeve 17 is fixedly connected with a rubber strip 20, the inner bottom of the mounting sleeve 17 is fixedly connected with a spring 18, the end of the spring 18 away from the inner bottom of the mounting sleeve 17 is fixedly connected to the limiting rod 19, the limiting rod 19 is sleeved with the operating table 1, the rubber strip 20 abuts against the limiting rod 19, the rubber strip 20 increases the friction between the limiting rod 19 and the mounting sleeve 17, and then adds damping to the movement of the rubber strip 20, the limiting rod 19 coincides with the axis of the downward pressure rod 16, the diameter of the limiting rod 19 is equal to the diameter of the downward pressure rod 16, the downward movement of the downward pressure rod 16 pushes the limiting rod 19 to move downward, and a convex strip 21 is fixedly connected to the top end surface of the operating table 1.

[0028] The motor 9 rotates to drive the connecting arm 11 to rotate, and further drives the feed clamp 12 to rotate. The feed clamp 12 passes through the bottom of the storage barrel 8. The steel plate in the storage barrel 8 is clamped by the feed clamp 12 under the elastic action of the two sets of elastic members 13. Then the feed clamp 12 rotates further to move the steel plate to the bottom of the upper die 5. The stopper 14 is blocked by the limit rod 19, so that the steel plate is aligned with the upper die 5 and the lower die 6, thereby improving the accuracy of stamping and cutting. Then, the upper die 5 is driven by the hydraulic cylinder 3 to push the transmission shaft 4 and the upper die 5 downward to stamp and cut the steel plate. The transmission shaft 4 When moving downward, the pressure rod 16 is driven to move downward, and the downward movement of the pressure rod 16 pushes the limit rod 19 to move downward. When the stamping and cutting is completed, the transmission shaft 4 and the pressure rod 16 move downward. The rubber strip 20 increases the friction between the limit rod 19 and the mounting sleeve 17, thereby adding damping to the movement of the rubber strip 20, so that the limit rod 19 slowly rises under the elastic push of the spring 18. At this time, the motor 9 drives the feeding clamp 12 to pass above the limit rod 19 and push the stamping part out between the upper die 5 and the lower die 6, which is convenient for the operator to take and improves the safety of the operator.

[0029] In addition, a convex strip 21 is fixedly connected to the top end face of the operating table 1. When the feed clamp 12 clamps the steel plate, the convex strip 21 presses against the steel plate, making it easier for the steel plate to enter between the two sets of elastic members 13, thereby improving the accuracy and efficiency of the operation and ensuring that the steel plate can be accurately moved to the stamping position after being clamped, while reducing errors or waste that may be caused by inaccurate clamping. At the same time, since the side of the convex strip 21 is curved, it will not affect the movement of the feed clamp 12 with the steel plate.

[0030] In the utility model, when in use, the motor 9 drives the connecting arm 11 and the feeding clamp 12 to rotate, the steel plate is clamped by the feeding clamp 12, and the stopper 14 is blocked by the limiting rod 19, so that the steel plate is aligned with the upper die 5 and the lower die 6, and the hydraulic cylinder 3 drives the upper die 5 to move downward to punch and cut the steel plate, and then the motor 9 drives the feeding clamp 12 to rotate through the top of the limiting rod 19, and pushes the stamped part out between the upper die 5 and the lower die 6, so that the operator can take it easily. Furthermore, in the process of the feeding clamp 12 clamping the steel plate, the convex strip 21 presses against the steel plate, making it easier for the steel plate to enter between the two sets of elastic members 13, ensuring that the steel plate can be accurately moved to the stamping position after being clamped.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
