Press slide damping structure

Abstract

A press slide damping structure includes a frame, a base mounted on the frame, a slide mounted on the base and vertically movably mounted on the base by a guide rod for mounting an upper die assembly, and a crankshaft assembly fixedly mounted on the frame and connected to the slide for transmission. The slide includes a main body and connecting portions formed at both ends of the main body. The lower end of each connecting portion is fixedly connected to the end of a guide rod movably connected to the base. Two sets of elastic structures are provided on the frame, each connected to the upper end of the connecting portion, to provide elastic tension in the direction away from the base. In this technical solution, the elastic structures are located on the connecting portions at both ends of the slide. When the slide moves downwards to complete actions such as stamping and pressing, the two sets of elastic structures can simultaneously apply elastic tension to both ends of the slide, thereby smoothly buffering the slide and reducing the direct impact force of the slide on the equipment.

Description

Technical Field

[0001] This utility model relates to the field of press equipment technology, specifically to a press slide damping structure. Background Technology

[0002] A press, including punch presses and hydraulic presses, is mainly used for processes such as cutting, punching, and blanking. It uses a crankshaft to drive the upper slide and the upper die assembly mounted on the slide to move vertically, thereby completing the operation.

[0003] The slider is movably connected to the base via a guide rod, and the crankshaft is driven by a connecting rod to enable the slider to reciprocate in the vertical direction, thereby driving the upper mold assembly to move and perform actions such as pressing and stamping.

[0004] In order to cushion the movement of the slider towards the base, a buffer structure is usually set between the slider and the base. Currently, the conventional method is to set an airbag on the slider and the base, and use the air pressure inside the airbag to achieve the buffering effect, so as to avoid excessive impact force when the upper mold assembly moves towards the base and damages the equipment.

[0005] However, since the buffer structure is located between the base and the slider, the space is small. At the same time, the space between the base and the slider is also the working space for pressing, stamping and other processing operations, which makes it inconvenient to maintain the buffer structure.

[0006] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0007] The purpose of this utility model is to provide a vibration damping structure for a press slide to solve the above-mentioned technical problems. The utility model adopts the following technical solution: A press slide damping structure includes a frame, a base mounted on the frame, a slide located above the base and movably mounted on the base in a vertical direction by a guide rod for mounting an upper mold assembly, and a crankshaft assembly fixedly mounted on the frame and driven by the slide. The slide includes a main body and connecting portions formed at both ends of the main body. The lower end of the connecting portion is fixedly connected to the end of the guide rod movably connected to the base. Two sets of elastic structures are provided on the frame and respectively connected to the upper ends of the connecting portions to provide elastic tension in the direction away from the base.

[0008] Furthermore, the elastic structure includes: A crossbeam formed on the frame, and the crossbeams are located above the connecting part and are opposite to each other; At least one tie rod is slidably disposed on the crossbeam, one end of the tie rod passing through the crossbeam and fixedly connected to the connecting part; A compression spring is sleeved on the end of the pull rod located on the crossbeam away from the connecting part, and the end of the pull rod is provided with a cover that presses the compression spring onto the crossbeam.

[0009] Furthermore, a threaded hole is provided on the cover, and an external thread is provided on the end of the pull rod to be screwed onto the cover.

[0010] Furthermore, a lower end cap is provided on the pull rod, the lower end cap is sleeved on the end of the pull rod located on the upper side of the crossbeam, and a lower groove is formed on the end face of the lower end cap for receiving the lower end of the compression spring therein.

[0011] Furthermore, an upper groove is formed on the end face of the cover facing the compression spring, and the upper groove accommodates the upper end of the compression spring within it.

[0012] Furthermore, each of the connecting parts is fixedly provided with the same number of guide rods as the pull rods and slidably connected to the base, and each guide rod is coaxially arranged with the pull rods.

[0013] The beneficial effects of this utility model are as follows: In the technical solution provided in this embodiment, the connecting parts at both ends of the slider are movably connected to the base via guide rods, and two elastic structures connected to the connecting parts are respectively provided on the frame, thereby elastically pulling the two ends of the slider. The main body of the slider is used to install the upper mold assembly. When the slider is driven by the crankshaft to reciprocate along the axis of the guide rod, when the slider moves downward, it can pull the elastic structure connected to the connecting parts, causing the elastic structure to generate elastic potential energy. Under the action of elastic potential energy, the slider can be buffered. In this technical solution, by providing elastic tension to the slider through the elastic structure on the upper side of the slider, the elastic structure is kept away from the working space of the press, which improves safety during maintenance. Furthermore, since the elastic structure is set between the frame and the connecting parts, a larger operating space can be obtained after removing the guard plate on the frame, making it easier to inspect and maintain the elastic structure.

[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0020] This utility model embodiment provides a vibration damping structure for a press slide block 130. By providing an elastic structure above the slide block 130, an elastic pulling force can be provided to the slide block 130, which is driven by the crankshaft assembly 140 through the connecting rod 141 to reciprocate in the vertical direction. Thus, the slide block 130 is buffered under the action of the elastic pulling force. In this technical solution, the elastic structure is set on the connecting parts 132 at both ends of the slide block 130. When the slide block 130 moves downward to complete the process of stamping, pressing and other actions, the two sets of elastic structures can simultaneously apply elastic pulling force to both ends of the slide block 130, thereby smoothly buffering the slide block 130 and reducing the direct impact force of the slide block 130 on the equipment.

[0021] Specifically, such as Figure 1-4 As shown, the shock-absorbing structure of the press slide 130 provided in this embodiment includes a frame 100, a base 110 disposed on the frame 100, a slide 130 located above the base 110 and movably disposed on the base 110 in the vertical direction by a guide rod 111 for mounting the upper mold assembly 120, and a crankshaft assembly 140 fixedly mounted on the frame 100 and connected to the slide 130 in a transmission manner. The slide 130 includes a main body 131 and connecting parts 132 formed at both ends of the main body 131. The lower end of the connecting part 132 is fixedly connected to the end of the guide rod 111 movably connected to the base 110. Two sets of elastic structures are disposed on the frame 100 and respectively connected to the upper end of the connecting part 132 to provide elastic tension in the direction away from the base 110.

[0022] During use, the connecting parts 132 at both ends of the slider 130 are movably connected to the base 110 via guide rods 111. Two elastic structures, each connected to the connecting parts 132, are respectively provided on the frame 100, thereby elastically pulling the two ends of the slider 130. The main body 131 of the slider 130 is used to mount the upper mold assembly 120. When the slider 130 is driven by the crankshaft to reciprocate along the axis of the guide rods 111, when the slider 130 moves downwards, it can pull the elastic structures connected to the connecting parts 132. The movement causes the elastic structure to generate elastic potential energy, which can buffer the slider 130 under the action of elastic potential energy. In this technical solution, by setting an elastic structure on the upper side of the slider 130 to provide elastic tension to the slider 130, the elastic structure is avoided from the working space of the press, which makes the maintenance process safer. In addition, since the elastic structure is set between the frame 100 and the connecting part 132, a larger operating space can be obtained after the guard plate on the frame 100 is removed, which makes it easier to inspect and maintain the elastic structure.

[0023] In this technical solution, such as Figure 2-4 As shown, the elastic structure includes a crossbeam 112 formed on the frame 100, with the crossbeam 112 located above the connecting portion 132 and facing each other; it also includes at least one pull rod 201 slidably disposed on the crossbeam 112, one end of the pull rod 201 passing through the crossbeam 112 and fixedly connected to the connecting portion 132; and a compression spring 202 sleeved on the end of the pull rod 201 located on the crossbeam 112 away from the connecting portion 132, and the end of the pull rod 201 is provided with a cover 203 that presses the compression spring 202 onto the crossbeam 112.

[0024] In this technical solution, the pull rod 201 is slidably mounted on the crossbeam 112, with both ends of the pull rod 201 located on both sides of the crossbeam 112. One end is fixedly connected to the connecting part 132, and the other end is sleeved with a compression spring 202. The compression spring 202 is restricted between the crossbeam 112 and the cover 203 by the cover 203. Thus, when the slider 130 moves downward driven by the crankshaft, it can drive the pull rod 201 to move. The cover 203 can then compress the compression spring 202, causing the compression spring 202 to generate elastic potential energy, thereby elastically pulling the slider 130 to achieve buffering and shock absorption of the slider 130. It is worth noting that the structure of the compression spring 202 sleeved on the pull rod 201 for buffering and shock absorption can provide a movable support inside the compression spring 202 during the compression process, thereby preventing the compression spring 202 from twisting its axis during compression. Furthermore, by compressing the compression spring 202 through the pull rod 201 and the cover 203 to generate elastic potential energy, the elastic force can be applied to the slider 130 through the pull rod 201. In this embodiment, the pull rod 201 is threaded to the slider 130, which ensures the effect of the elastic force on the slider 130 and makes the process of shock absorption and buffering by the elastic force more stable.

[0025] In this embodiment, a threaded hole is provided on the cover 203, and an external thread is provided on the end of the pull rod 201 to be screwed onto the cover 203. The cover 203 is threadedly connected to the pull rod 201, thereby restricting the compression spring 202. At the same time, the elastic force of the spring 202 can be adjusted by tightening or loosening the cover 203, thereby changing the buffering and shock absorption performance of the slider 130.

[0026] In this embodiment, in order to improve the stability of the spring 202 during continuous compression and expansion, and to prevent the spring 202 from tilting due to displacement caused by continuous compression and expansion, thus affecting the buffering and shock absorption effect on the slider 130, as follows: Figure 4 As shown, a lower end cap 204 is also provided on the pull rod 201. The lower end cap 204 is sleeved on one end of the pull rod 201 located on the upper side of the crossbeam 112, and a lower groove 2041 is formed on the end face of the lower end cap 204 for receiving the lower end of the compression spring 202 therein.

[0027] In the working state, the lower end cover 204 is sleeved on the pull rod 201. Specifically, a hole is formed on the lower end cover 204 for the pull rod 201 to pass through, thereby enabling the lower end cover 204 and the pull rod 201 to be radially limited. After the compression spring 202 is sleeved on the pull rod 201, the lower end of the spring 202 is received in the lower groove 2041. The setting of the lower groove 2041 can limit the radial displacement of the lower end of the compression spring 202, thereby preventing the compression spring 202 from being displaced.

[0028] In a further technical solution, in order to further improve the stability of the compression spring 202 during operation, an upper groove is formed on the end face of the cover 203 facing the compression spring 202, and the upper groove accommodates the upper end of the compression spring 202 within it.

[0029] During the buffer retrieval process, the upper and lower grooves can restrict the upper and lower ends of the compression spring 202, thereby effectively preventing the compression spring 202 from tilting due to end displacement during compression, thus ensuring the stability of the compression spring 202 during operation.

[0030] In this technical solution, in order to enable the slider 130 to reciprocate in the vertical direction, each connecting part 132 is fixedly provided with the same number of guide rods 111 as the pull rods 201 and slidably connected to the base 110, and each guide rod 111 is coaxially arranged with the pull rod 201.

[0031] In this technical solution, each connecting part 132 is provided with two guide rods 111 arranged side by side, and similarly, two pull rods 201 are also provided. The axes of each pull rod 201 and the guide rod 111 are set to be collinear, which can ensure high stability when the compression spring 202 is compressed to achieve vibration reduction.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
