Description

Technical Field

[0001] This utility model relates to the field of riveting technology, specifically to a riveting mold and riveting fixture. Background Technology

[0002] Riveting is an important assembly method in workpiece processing. Existing riveting equipment can be found in patent application number CN201721859659.8, which has an upper template and a lower template. The upper or lower template usually has a limiting groove. After the workpiece to be riveted is placed in the limiting groove, the upper and lower templates clamp the workpiece to complete the riveting. However, in order to effectively fix the workpiece, the inner wall of the limiting groove needs to fit tightly against the workpiece. The riveted workpiece usually undergoes a small radial deformation, resulting in an interference fit between the workpiece and the limiting groove, making it difficult to remove the riveted workpiece from the limiting groove.

[0003] Therefore, how to reduce the difficulty of removing the workpiece from the mold is an urgent technical problem to be solved. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a riveting mold and riveting fixture to solve the technical problem in the prior art where the mold slot is tightly fitted to the workpiece, making it difficult for the workpiece to detach from the mold.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] On the one hand, this utility model provides a riveting die, which includes:

[0007] Base;

[0008] A clamping assembly includes a first clamping block, a second clamping block, and an elastic element. The first and second clamping blocks are slidably disposed on the base. The elastic element is connected to the first and second clamping blocks at both ends. The elastic element has a first state where it accumulates elastic potential energy to allow the first and second clamping blocks to close together and form a limiting groove, and a second state where it releases the elastic potential energy to allow the first and second clamping blocks to move away from each other.

[0009] The pressure seat includes a pressure seat body, a first wedge block, and a second wedge block. The pressure seat body is slidably disposed on the base. When the pressure seat body is close to the base, the first wedge block and the second wedge block push the first clamping block and the second clamping block respectively, so that the elastic element switches from a second state to a first state.

[0010] In some embodiments, the base is provided with a guide groove, and both the first clamping block and the second clamping block are slidably disposed in the guide groove.

[0011] In some embodiments, the base has a first limiting portion and a second limiting portion. The first limiting portion is disposed at one end of the guide groove to prevent the first clamping block from passing through, and the second limiting portion is disposed at the other end of the guide groove to prevent the second clamping block from passing through.

[0012] In some embodiments, the base has a first positioning groove, and the first clamping block and the second clamping block are symmetrically arranged with the first positioning groove as the center.

[0013] In some embodiments, the pressure seat has a second positioning groove, which corresponds to the first positioning groove.

[0014] In some embodiments, the elastic element includes a spring, with its two ends connected to the first clamping block and the second clamping block, respectively.

[0015] In some embodiments, the base has a plurality of guide rods, and the pressure seat has a plurality of guide holes, with each of the guide holes corresponding to one of the guide rods.

[0016] In some embodiments, a locking key is formed at one end of the first clamping block near the second clamping block, and a locking groove is formed at one end of the second clamping block near the first clamping block. When the elastic member is in the first state, the locking key is embedded in the locking groove.

[0017] In some embodiments, the first clamping block has a first guide surface corresponding to the first wedge, and the second clamping block has a second guide surface corresponding to the second wedge.

[0018] On the other hand, this utility model also provides a riveting fixture, which is equipped with the above-mentioned riveting mold.

[0019] Compared with existing technologies, the riveting die provided by this utility model has the following advantages: First, the workpiece to be riveted is placed on the base. Then, the pressing body is pushed close to the base, causing the first wedge and the second wedge to push the first clamping block and the second clamping block respectively. This causes the elastic element to switch to the second state, and the first clamping block and the second clamping block together form a limiting groove, allowing the workpiece to be embedded in the limiting groove. As the pressing body continues to move, the workpiece can be riveted using the pressing body. After riveting is completed, the pressing body moves away from the base, and the elastic element returns to the second state, causing the first clamping block and the second clamping block to move away from each other, so that the workpiece can be removed from the die.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] To address the technical problem of reducing the difficulty of workpiece removal from the mold, this utility model provides a riveting mold in which, after the riveting operation is completed, the components that form a limiting groove move away from each other, so that the workpiece can be removed from the mold.

[0027] It should be noted that the riveting die of this utility model is used for, but not limited to, riveting tooling. For ease of explanation, this utility model will only use the application of the riveting die to riveting tooling as an example. The principle of the riveting die applied to other types of equipment is essentially the same as that applied to riveting tooling, and will not be described in detail here.

[0028] Please see Figure 1 , Figure 1This is a schematic diagram of the riveting mold in one embodiment of the present invention. The riveting mold includes a base 100, a clamping assembly 200, and a pressure seat 300. The clamping assembly 200 includes a first clamping block 210, a second clamping block 220, and an elastic member 230. The first clamping block 210 and the second clamping block 220 are slidably disposed on the base 100. The two ends of the elastic member 230 are respectively connected to the first clamping block 210 and the second clamping block 220. The elastic member 230 has a first state in which it accumulates elastic potential energy so that the first clamping block 210 and the second clamping block 220 surround each other to form a limiting groove, and a second state in which it releases elastic potential energy so that the first clamping block 210 and the second clamping block 220 move away from each other. The pressure seat 300 includes a pressure seat body, a first wedge block 310 and a second wedge block 320. The pressure seat body is slidably disposed on the base 100. When the pressure seat body is close to the base 100, the first wedge block 310 and the second wedge block 320 push the first clamping block 210 and the second clamping block 220 respectively, so that the elastic member 230 switches from the second state to the first state.

[0029] In this embodiment, the workpiece to be pressed is first placed on the base 100. Then, the pressing body is pushed close to the base 100, causing the first wedge 310 and the second wedge 320 to push the first clamping block 210 and the second clamping block 220 respectively. This causes the elastic element 230 to switch to the second state, and the first clamping block 210 and the second clamping block 220 together form a limiting groove, allowing the workpiece to be embedded in the limiting groove. As the pressing body continues to move, the workpiece can be riveted using the pressing body. After riveting is completed, the pressing body moves away from the base 100, and the elastic element 230 returns to the second state, causing the first clamping block 210 and the second clamping block 220 to move away from each other, so that the workpiece can be removed from the mold.

[0030] In some embodiments, the base 100 has a guide groove 110, and the first clamping block 210 and the second clamping block 220 are both slidably disposed in the guide groove 110. Under the guidance of the guide groove 110, the first clamping block 210 and the second clamping block 220 can slide relative to the base 100.

[0031] Based on the above embodiments, in some embodiments, the base 100 has a first limiting part 120 and a second limiting part 130. The first limiting part 120 is disposed at one end of the guide groove 110 to prevent the first clamping block 210 from passing through, and the second limiting part 130 is disposed at the other end of the guide groove 110 to prevent the second clamping block 220 from passing through. Since the first limiting part 120 and the second limiting part 130 play a limiting role, under the elastic force of the elastic member 230, the first clamping block 210 and the second clamping block 220 respectively press against the first limiting part 120 and the second limiting part 130, thereby positioning the first clamping block 210 and the second clamping block 220 so that the first wedge 310 and the second wedge 320 can be smoothly aligned with the first clamping block 210 and the second clamping block 220.

[0032] In some embodiments, the base 100 has a first positioning groove 140, and the first clamping block 210 and the second clamping block 220 are symmetrically arranged with the first positioning groove 140 as the center. The first positioning groove 140 can position the workpiece to be riveted, so that the first clamping block 210 and the second clamping block 220 are aligned with the workpiece to be clamped.

[0033] Based on the above embodiments, in some embodiments, the pressure seat 300 is provided with a second positioning groove 330, which corresponds to the first positioning groove 140. The second positioning groove 330 can position the top of the workpiece.

[0034] Any implementation of the elastic element 230 that can push the first clamping block 210 and the second clamping block 220 away from each other is feasible. In some embodiments, the elastic element 230 includes a spring, with the two ends of the spring connected to the first clamping block 210 and the second clamping block 220, respectively.

[0035] In some embodiments, the base 100 has a plurality of guide rods 150, and the pressure seat 300 has a plurality of guide holes 340, which are correspondingly fitted onto the plurality of guide rods 150. Under the guidance of each guide rod 150, the pressure seat 300 can move along the guide rods 150.

[0036] In some embodiments, a locking key 211 is formed at the end of the first clamping block 210 near the second clamping block 220, and a locking groove 221 is formed at the end of the second clamping block 220 near the first clamping block 210. When the elastic member 230 is in the first state, the locking key 211 is embedded in the locking groove 221. Because the locking key 211 is embedded in the locking groove 221, it ensures that the first clamping block 210 and the second clamping block 220 can accurately mate with each other, which helps to improve the accuracy of the limiting groove formed by the encirclement.

[0037] In some embodiments, the first clamping block 210 has a first guide surface corresponding to the first wedge block 310, and the second clamping block 220 has a second guide surface corresponding to the second wedge block 320. Since the first clamping block 210 and the second clamping block 220 have the first guide surface and the second guide surface respectively, the first wedge block 310 and the second wedge block 320 can push the first clamping block 210 and the second clamping block 220 more smoothly.

[0038] In addition, this utility model also provides a riveting fixture, which is equipped with the above-mentioned riveting mold.

[0039] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below:

[0040] First, the workpiece to be pressed is placed in the first positioning groove 140. Then, the pressing base body is pushed, and under the guidance of the guide rod 150, the pressing base body moves closer to the base 100. This causes the first wedge 310 and the second wedge 320 to push the first clamping block 210 and the second clamping block 220 respectively, causing the elastic element 230 to switch to the second state. The first clamping block 210 and the second clamping block 220 then form a limiting groove, allowing the workpiece to be embedded within the limiting groove. As the pressing base body continues to move, it can be used to rivet the workpiece. After riveting is completed, the pressing base body moves away from the base 100. At this time, the elastic element 230 returns to the second state, causing the first clamping block 210 and the second clamping block 220 to move away from each other, facilitating the removal of the workpiece from the mold.
