Description

Technical Field

[0001] The utility model relates to the technical field of stamping equipment, in particular to a protective cover for stamping equipment. Background Art

[0002] Stamping equipment is a mechanical device used to process metal plates or strips into specific shapes through molds. Stamping equipment is used to plastically deform metal materials. Through stamping dies, metal plates are punched, sheared, bent, stretched, etc. to obtain the required metal parts or products. It can be used to manufacture various metal products such as automotive parts, electronic product casings, furniture hardware accessories, home appliance panels, etc.

[0003] A Chinese patent discloses a stamping device (authorization announcement number CN220760696U). The patented technology includes a stamping machine frame, a driving seat, and a driving device that drives the driving seat to perform linear reciprocating motion. A stamping seat is fixed to the bottom of the driving device. A stamping base that cooperates with the stamping seat is also provided on the stamping machine frame. An annular flange is provided on the stamping base. A cavity that is coaxial with the annular flange and extends downward is provided inside the stamping base. A top plate is provided in the cavity, and a push rod is fixed on the upper surface of the top plate. It also includes a driving structure located in the cavity below the top plate, and the driving structure is used to drive the top plate to move along the height direction of the cavity so that the push rod pushes out the stamped part. During the stamping process, the utility model uses the driving structure to move the top plate upward, thereby pushing out the metal gasket, and uses a lightweight spring to reset it to avoid affecting the next stamping process.

[0004] This patented technology is effective in stamping metal gaskets when used, but there are still some shortcomings when used. There are no protective measures at the stamping structure. During the loading and unloading process, the hands frequently move under the stamping equipment. If the stamping equipment lacks appropriate protective structures during the processing process, the operator's hands may come into contact with moving parts such as punches, which may cause hand injuries if not careful. Therefore, those skilled in the art provide a protective cover for stamping equipment to solve the problems raised in the above background technology. Utility Model Content

[0005] 1. Technical solution

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a protective cover for stamping equipment, comprising a bottom plate,

[0008] The punching structure includes a hydraulic rod, a support frame fixed above the base plate, a travel groove provided inside the support frame, a fixed die fixed inside the travel groove, and a punch located at the telescopic end of the hydraulic rod;

[0022] 2. Beneficial effects

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] The utility model uses a hydraulic rod to drive the punch to descend and perform stamping on the parts inside the fixed die. During the stamping process, the driving force of the telescopic end of the hydraulic rod drives the support ring and the protective cover to descend. The protective cover is elastically installed by a spring and contracts when squeezed. At the moment of contact with the hand, the elastic part contracts to prevent the hand from being directly crushed. If the hand fails to leave the bottom of the stamping structure in time due to careless operation, a buffer time is provided for the worker to withdraw the hand, thereby protecting the worker and reducing the safety hazards during the use of the stamping equipment.

[0025] At the same time, when the telescopic end of the hydraulic rod descends, the top plate outside the fixed mold is gradually lifted through the meshing transmission of tooth plate 1, tooth plate 2 and the gear. When the lifting push arm is lifted, it reminds the staff, thereby improving the protection of the staff.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0042] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0043] Example 1

[0044] See also Figures 1-6 As shown, this embodiment is a protective cover for a stamping device, comprising a bottom plate 100,

[0045] The punching structure 200 includes a hydraulic rod 203, a support frame 201 fixed above the base plate 100, a travel groove 205 defined within the support frame 201, a fixed die 202 fixed within the travel groove 205, and a punch 204 located at the telescopic end of the hydraulic rod 203;

[0046] The protective structure 300 includes a fixing ring 301 and a support ring 304 sleeved on the outside of the hydraulic rod 203, springs 307 fixed inside the fixing ring 301 and the support ring 304 and distributed in a circular array, a protective cover 305 fixed at the lower end of the support ring 304, and a fixing frame 303 fixed to the fixing ring 301 and the outer wall of the telescopic end of the hydraulic rod 203.

[0047] The upper end of the support ring 304 is provided with guide rods 302 distributed in a circular array. The interior of the fixing ring 301 is provided with through holes 308 distributed in a circular array. The guide rods 302 are slidably inserted into the through holes 308 and are inside the springs 307.

[0048] The outer side of the spring 307 is sleeved with a telescopic sleeve 309 with upper and lower ends fixed between the fixing ring 301 and the support ring 304, and the lower end of the protective cover 305 is provided with a rubber ring 306;

[0049] Use of protective structure 300;

[0050] The part is placed in the fixed die 202, and the hydraulic rod 203 drives the punch 204 to move longitudinally, driving the punch 204 to stamp the part so that the part is formed into a specific shape. During this process, the telescopic end of the hydraulic rod 203 drives the fixed frame 303 to move longitudinally, and then drives the fixed ring 301 to move longitudinally. The fixed ring 301 drives the support ring 304, the protective cover 305 and the rubber ring 306 to move longitudinally through the spring 307. The protective cover 305 moves longitudinally, and because its lower end is lower than the punch 204, it first contacts the intercepted object during stamping, including the hands of the staff who have not moved out from under the stamping equipment in time. The hands first contact the rubber ring 306 The rubber ring 306 has a flexible structure, which can prevent the staff from being directly pinched when it contacts the staff. At this time, it reminds the staff to move their hands out from under the stamping structure 200, which serves as a reminder. It is worth noting that the stamping equipment needs to slowly drive the punch 204 down a certain distance, so that the protective cover 305 squeezes the support frame 201, and then applies the stamping force for part processing. The protective cover 305 pressurizes the support frame 201 at a distance. The equipment operates slowly, providing the staff with time to withdraw their hands, thereby effectively protecting the staff. Even if the staff's hands are not withdrawn in time, the squeezed hands are prevented from causing greater injuries through the elastic connection of the spring 307.

[0051] Example 2

[0052] See also Figures 1-6 As shown, this embodiment is based on embodiment 1 and also includes:

[0053] as well as;

[0054] Protective structure 2 400 includes a sealing ring 405 embedded in the inner wall of travel groove 205, a top plate 404 slidingly attached to sealing ring 405 and located on the front and rear sides of fixed mold 202, a tooth plate 1 401 fixedly connected to fixing ring 301, a gear 402 meshing with tooth plate 1 401, and a tooth plate 2 403 meshing with gear 402 and located below support frame 201;

[0055] A guide rail 407 is provided at the upper end of the bottom plate 100, and a slider 408 is provided at the end of the tooth plate 401. The slider 408 is slidably installed inside the guide rail 407.

[0058] Carry out the use of protective structure II 400;

[0059] When the telescopic end of the hydraulic rod 203 moves longitudinally, it drives the tooth plate 401 to descend, and the tooth plate 401 pushes the gear 402, thereby lifting the tooth plate 2 403 installed in meshing relationship, and the tooth plate 2 403 drives the top plate 404 to rise through the fixed rod 406, which has the same function as the protective structure 1 300, except that the top plate 404 moves from bottom to top, and warns hands at different heights. When the hand position is in a low position or is in contact with the upper end of the support frame 201, the top plate 404 lifts and contacts to warn the staff to move their hands out. The top plate 404 is inside the protective cover 305 and does not hinder the use of the protective structure 1 300, thereby improving the protection effect on the hands when the stamping equipment is used.
