Abstract

The utility model relates to the technical field of precision machining, in particular to a precision machining stamping device with a pressing structure, which comprises a shell and the pressing structure, and the pressing structure comprises a hydraulic cylinder, a fixing block and a spring rod. In the process that the hydraulic cylinder drives the pressing block to descend, a part placed at the lower end needs to be fixed firstly, and the situation that follow-up machining is affected due to deviation of the part is prevented, so that in the descending process of the hydraulic cylinder, the contact block arranged at the lower end of the spring rod makes contact with the part firstly, and when the contact block makes contact with the part, the contact block does not make contact with the part. The part can be fixed firstly, operation and movement of the part are limited, so that the part is stamped through the pressing block, the situation that the pressing block is damaged due to the fact that the pressing block is pressed obliquely and deviates can be avoided, in the pressing block rising process, the pressing block can be separated from the part firstly, then the contact block is lifted, and therefore the part can be fixed conveniently. Therefore, the situation that the stamped part is adhered to the pressing block and further needs to be peeled off manually subsequently can be prevented.

Description

Technical Field

[0001] The utility model relates to the technical field of precision mechanical processing, in particular to a precision processing punching device with a clamping structure. Background Art

[0002] Precision machining is a process of changing a workpiece, which can be classified into cold machining and hot machining. When machining precision machinery, it is necessary to perform stamping on the machine, which requires the use of a stamping device. Stamping is a forming method in which a press and a die are used to apply external force to plates, strips, pipes, and profiles to cause plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. Stamping and forging belong to plastic processing, collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. 60% to 70% of the world's steel is sheet material, most of which is stamped into finished products. Automobile bodies, chassis, fuel tanks, radiators, boiler drums, container shells, motors, electrical appliances, and iron core silicon steel sheets are all stamped. There are also a large number of stamped parts in products such as instruments and meters, household appliances, bicycles, office machinery, and daily utensils.

[0003] After searching, a utility model patent with publication number CN214392050U specifically discloses a precision stamping device for sheet metal processing, including a stamping machine head, a fixed machine base, an electric telescopic rod, a feeding box, a supporting plate, an active pulley, a transmission belt, a driven pulley, a driving motor, an active feeding roller and a feeding top plate. The stamping machine head is installed on the upper side of the fixed machine base, the supporting plate is installed on the upper side of the left end surface of the fixed machine base, the feeding box is installed on the upper side of the supporting plate, the electric telescopic rod is installed on the left side of the feeding box, the feeding top plate is installed on the right end surface of the electric telescopic rod, the driving motor is installed on the lower end surface of the supporting plate, the driving pulley is installed on the front side of the driving motor, the active feeding roller is installed on the right side of the feeding box, the driven pulley is installed on the front side of the active feeding roller, and a transmission belt is connected and installed between the active pulley and the driven pulley. This design solves the problem of slow manual feeding speed of the original precision stamping device for sheet metal processing. The utility model has a reasonable structure, is convenient for rapid feeding operation of workpieces, and has high processing efficiency.

[0004] The above patent only realizes the operation of rapid loading of workpieces by means of an electric telescopic rod, a loading box, a support plate, an active pulley, a transmission belt, a driven pulley, a drive motor, an active loading roller and a loading top plate. However, the device does not have a clamping structure, cannot limit and fix the materials to be processed, cannot prevent the position of the materials from moving during the processing, and has an adverse effect on the processing of the materials. It cannot avoid processing errors and waste caused by the offset of the material position.

[0005] Therefore, it is necessary to invent a precision machining stamping device with a clamping structure to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a precision machining stamping device with a clamping structure to solve the problems raised in the above background technology.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a precision machining stamping device with a clamping structure, comprising a shell and a clamping structure, the clamping structure comprising a hydraulic cylinder, a fixed block, a spring rod, a contact block and a pressure block, the upper end of the shell is provided with a hydraulic cylinder, the lower end of the hydraulic cylinder is fixedly installed with a fixed block, the lower end of the fixed block is provided with a spring rod, the lower end of the spring rod is fixedly installed with a contact block, and the lower end of the fixed block is fixedly installed with a pressure block.

[0008] Preferably, a base is fixedly mounted on the lower end of the shell, a soundproof cover is provided on the upper end of the shell, a protective door is connected to one side of the soundproof cover, and a bottom plate is fixedly mounted on the upper end of the shell.

[0009] Preferably, the sound insulation cover is supported by PVC plastic material, and the sound insulation cover is arranged in a "rectangular" structure.

[0010] Preferably, four spring rods are provided, and the four spring rods are symmetrically distributed at the lower end of the fixing block, and the four spring rods are symmetrically arranged about the central axis of the fixing block.

[0012] Preferably, an electric slide rail is provided on one side of the movable sleeve, a slider is connected to the other side of the electric slide rail, a damping reset rod is fixedly installed on the other side of the slider, and a clamp is fixedly installed on the other end of the damping reset rod.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. Through the arrangement of the hydraulic cylinder, the fixed block, the spring rod, the contact block and the pressing block, the hydraulic cylinder needs to fix the parts placed at the lower end first in the process of driving the pressing block to descend, so as to prevent the parts from running off and affecting the subsequent processing. Therefore, in the process of the hydraulic cylinder descending, the contact block arranged at the lower end of the spring rod first contacts the parts. When the contact block contacts the parts, the parts can be fixed first to limit the operation and activity of the parts. Therefore, when the parts are stamped by the pressing block, it can be ensured that the pressing block will not be distorted or deviated to cause damage to the pressing block. In addition, in the process of the pressing block rising, the pressing block can be separated from the parts first, and then the contact block can be lifted, so as to prevent the stamped parts from adhering to the pressing block and requiring subsequent manual peeling, thereby bringing convenience to the stamping device and making the use effect of the stamping device more ideal.

[0015] 2. Through the setting of electric slide rails, sliders, damping reset rods and clamps, the electric slide rails are used in conjunction with the sliders to adjust the position of the clamps according to the volume of the punched object, ensuring that the clamps can be fixed in the middle position of the punched object, thereby increasing the stability of the fixation of the punched object. The setting of the damping reset rod can adjust the distance between the clamps according to the volume of the punched object, making the clamps more flexible in clamping.
