Description

Technical Field

[0001] This utility model relates to the field of jigs, and more particularly to a stamping jig. Background Technology

[0002] Stamping fixtures are common industrial components used to apply pressure to products to give them a specific shape. During use, the operator typically places the product in the stamping position and removes it after stamping. It's important to note that to achieve product forming or clamping, a rapid movement of the slide block is usually necessary to generate significant impact force; this is typically achieved using a cylinder. In practice, a sudden interruption of air supply to the cylinder can cause it to lose control, potentially resulting in the slide block suddenly falling and injuring the operator. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to provide a stamping fixture that, when the stamping fixture is in an idle state, fixes the slider through a locking mechanism to prevent the slider from suddenly falling due to the loss of the driving source, thereby improving the safety performance of the stamping fixture.

[0004] To achieve the above objectives, the present invention aims to provide a stamping fixture, comprising:

[0005] A slider, the slider having a connecting part and an actuating part;

[0006] A driving component is connected to the connecting portion of the slider, and is used to drive the slider to switch between an idle state and an operating state;

[0007] In the idle state, there is a preset distance between the actuating part of the slider and the product to be processed on the processing station; in the working state, the actuating part of the slider presses the product to be processed on the processing station.

[0008] A locking mechanism includes a first hook block. When the stamping fixture is in the idle state, the locking mechanism has a locked state and an unlocked state. In the locked state, the first hook block contacts the slider and fixes the slider. In the unlocked state, the first hook block separates from the slider, so that the driving member can drive the slider to move towards the processing position.

[0009] In some embodiments, the locking mechanism includes a second hook block and a locking base, wherein the second hook block is fixedly connected to the slider, and the first hook block is movably mounted on the locking base;

[0010] In the locked state, the second hook block and the first hook block are engaged.

[0011] In the unlocked state, the second hook block and the first hook block are staggered;

[0012] The first hook block, which is movable relative to the locking base, can control the locking mechanism to switch between the unlocked state and the locked state.

[0019] The second hook block has a second limiting protrusion extending toward the first hook block at one end near the first hook block;

[0020] In the locked state, the second limiting protrusion enters the limiting groove, and the first limiting protrusion abuts against the second limiting protrusion;

[0021] The first limiting protrusion has a first guide surface on the side away from the limiting groove and a first locking surface on the side close to the limiting groove; the second limiting protrusion has a second guide surface on the side close to the first hook block and a second locking surface on the side away from the first hook block; during the process of the first limiting protrusion moving into the limiting groove, the first guide surface and the second guide surface abut against each other, which facilitates the second hook block to push the locking end to rotate away from the locking base; in the locked state, the second limiting protrusion moves into the limiting groove, and the first locking surface abuts against the second locking surface.

[0022] In some embodiments, the rotating part of the first hook block has a shaft hole; the locking base has a bracket corresponding to the position of the shaft hole;

[0023] The locking mechanism further includes a pivot pin that passes through the bracket and the pivot hole to rotatably connect the first hook block and the second hook block.

[0024] In some embodiments, the first hook block further includes a connecting rod and a handle ball, one end of the connecting rod being mounted on the side of the first hook block away from the locking base at the operating end, and the handle ball being mounted on the end of the connecting rod away from the first hook block.

[0025] In some embodiments, the first hook block is slidably mounted on the locking base, the locking base having a movable groove; the first hook block has a locking end and a sliding end, the sliding end being slidably mounted on the movable groove, the bottom of the locking end having a third guide surface, and the top of the locking end having a third locking surface; the end of the second hook block has a locking protrusion, the upper surface of the locking protrusion having a fourth guide surface, and the lower surface of the locking protrusion having a fourth locking surface; in the locked state, the third locking surface and the fourth locking surface abut against each other; in the unlocked state, the locking protrusion is separated from the locking end; the locking mechanism further includes an elastic member mounted between the sliding end and the bottom wall of the movable groove; in the unlocked state, the elastic member has a first state, and in the locked state, the elastic member has a second state, from the first state to the second state, the elastic member is compressed.

[0026] In some embodiments, the stamping fixture further includes:

[0027] One support plate;

[0028] A first support member, the bottom of which is fixed to the support plate, and a driving member is installed on the top of the first support member, with a preset angle between the driving member and the support plate;

[0029] At least one slide rail is installed on the support plate at a preset angle;

[0030] The slider is positioned above the slide rail and the drive component. The bottom of the slider has a sliding portion. The connecting portion is fixedly connected to the drive rod of the drive component. The sliding portion is slidably mounted on the slide rail.

[0031] In some embodiments, the stamping fixture further includes a limiting rod mounted on the support plate, and the slider further includes a limiting part located on one side of the actuating part, wherein in the working state, the limiting rod abuts against the limiting part.

[0032] Beneficial effects:

[0033] 1. In this application, when the stamping fixture is in an idle state, the slider is fixed by a locking mechanism to prevent the slider from falling suddenly due to the loss of the driving source of the stamping fixture, thereby improving the safety performance of the stamping fixture.

[0034] 2. In this application, the first limiting protrusion of the first hook block of the stamping fixture has a first guiding surface, and the second limiting protrusion of the second hook block has a second guiding surface. During the process of the second limiting protrusion moving into the limiting groove, the first guiding surface and the second guiding surface come into contact, which facilitates the second protrusion to push the first protrusion to move away from the locking base, and facilitates the second limiting protrusion to move into the limiting groove.

[0035] 3. In this application, an elastic element is provided between the operating end of the first hook block and the locking base. In the locked state, the elastic element is compressed, thereby allowing the elastic element to apply a thrust between the operating end and the locking base, preventing the distance between the operating end and the locking base from decreasing, thus enabling the locking end of the first hook block to be stably connected to the second hook block. In the unlocked state, the elastic element is compressed, and after the force acting on the operating end disappears, the operating end can move away from the locking base under the action of the elastic element, thereby automatically switching the locking mechanism from the unlocked state to the locked state.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0052] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0053] Reference manual attached Figures 1 to 8 This application provides a stamping fixture 100, which includes a slider 10, a drive member 20, and a locking mechanism 30. The slider 10 has a connecting part (not shown in the figure) and an actuating part 12. During use, the actuating part 12 can contact the product to be processed 200 to apply a certain pressure to the product to be processed 200.

[0054] refer to Figure 2 and Figure 3The stamping fixture 100 further includes a support plate 40, on which the slider 10 and the driving member 20 are respectively mounted. The support plate 40 has a processing position 41, on which the product to be processed 200 is adapted to be placed. During use, the actuating part 12 of the slider 10 can move to the processing position 41 to apply a certain pressure to the product to be processed 200.

[0055] Specifically, the processing position 41 has a placement rack 411, and the product to be processed 200 is adapted to be placed on the placement rack 411. The actuating part 12 of the slider 10 has a punch head 121, which can act on the product to be processed 200 during use to apply a certain pressure to the product to be processed 200. Preferably, there are two or more placement racks 411 and punch heads 121, so that the stamping fixture 100 can process two or more products to be processed 200 at the same time.

[0056] Specifically, the drive member 20 is connected to the connecting portion of the slider 10, and is used to drive the slider 10 to switch between an idle state and a working state. In the idle state, there is a preset distance between the actuating part 12 of the slider 10 and the product 200 to be processed on the processing station 41; in the working state, the actuating part 12 of the slider 10 presses the product 200 to be processed on the processing station 41.

[0057] The locking mechanism 30 includes a first hook block 31. When the stamping fixture 100 is in the idle state, the locking mechanism 30 has a locked state and an unlocked state. In the locked state, the first hook block 31 contacts the slider 10 and fixes the slider 10. In the unlocked state, the first hook block 31 can separate from the slider 10, release the slider 10, and enable the driving member 20 to drive the slider 10 to move towards the processing position 41, so that the stamping fixture 100 switches from the idle state to the working state.

[0058] Preferably, the driving component 20 is a cylinder. During actual operation, if the cylinder is continuously supplied with air, its movement is controlled, allowing the slider 10 to be fixed in either the idle or working state. However, if the air supply to the cylinder is suddenly cut off, its movement will be uncontrolled, and the slider 10 in the idle state will fall to the processing position 41 under gravity, posing a significant safety risk to the operator. In this application, the slider 10 is fixed in the idle state by the locking mechanism 30, preventing the slider 10 from suddenly falling due to loss of driving power, thus improving the safety performance of the stamping fixture.

[0059] refer to Figure 2 and Figure 3 The locking mechanism 30 further includes a second hook block 32 and a locking base 33. The second hook block 32 is fixedly connected to the slider 10, and the first hook block 31 is movably mounted on the locking base 33. In the locked state, the second hook block 32 and the first hook block 31 are engaged; in the unlocked state, the second hook block 32 and the first hook block 31 are offset. The movement of the first hook block 31 relative to the locking base 33 can control the locking mechanism 30 to switch between the unlocked state and the locked state.

[0060] In this application, the purpose of fixing the slider 10 in the idle state can be achieved by the cooperation of the first hook block 31 and the second hook block 32. The structure is simple, easy to implement, and low in cost.

[0061] refer to Figures 1 to 4 The stamping fixture 100 further includes a support pad 42, which is fixedly installed on the support plate 40 and located on one side of the slider 10. The locking base 33 is fixedly installed on the top of the support pad 42.

[0062] In some modified embodiments, the second hook block 32 is fixedly mounted to the support pad 42, and the locking base 33 is fixedly mounted to the slider 10. In some modified embodiments, the second hook block 32 and the slider 10 are integrally formed. In some modified embodiments, the slider 10 has a groove at a preset position, and in the locked state, at least a portion of the first hook block 31 extends into the groove and engages with the side wall of the groove.

[0063] refer to Figures 5 to 8The first hook block 31 is rotatably mounted on the locking base 33. The first hook block 31 has a locking end 311, an operating end 312, and a rotating portion 313 located between the locking end 311 and the operating end 312. The rotating portion 313 is rotatably mounted on the locking base 33. The locking end 311 is adapted to engage with the second hook block 32. Operating the operating end 312 controls the rotation of the first hook block 31 relative to the locking base 33, thereby changing the relative position of the locking end 311 relative to the locking base 33, and controlling the locking mechanism 30 to switch between the locked state and the unlocked state.

[0064] Preferably, the locking end 311 and the operating end 312 of the first hook block 31 are located on both sides of the rotating part 313. During operation, decreasing the distance between the operating end 312 and the locking base 33 increases the distance between the locking end 311 and the locking base 33; increasing the distance between the operating end 312 and the locking base 33 decreases the distance between the locking end 311 and the locking base 33. By changing the distance between the operating end 312 and the locking base 33, the locking mechanism 30 can be controlled to switch between the locked state and the unlocked state.

[0065] Furthermore, the locking mechanism 30 further includes an elastic element 34, which is disposed between the operating end 312 and the locking base 33. When the locking mechanism 30 is in the locked state, the elastic element 34 is in a first state; when the locking mechanism 30 is in the unlocked state, the elastic element 34 is in a second state. During the process of rotating the first hook block 31 to switch the locking mechanism 30 from the locked state to the unlocked state, the elastic element 34 is compressed from the first state to the second state. Preferably, the elastic element 34 is compressed in the first state, thereby enabling the elastic element 34 to apply a thrust between the operating end 312 and the locking base 33, preventing the distance between the operating end 312 and the locking base 33 from decreasing, thereby enabling the locking end 311 of the first hook block 31 to be stably connected to the second hook block 32. In the second state, the elastic element 34 is compressed. After the force acting on the operating end 312 disappears, the operating end 312 can move away from the locking base 33 under the action of the elastic element 34, thereby causing the locking mechanism 30 to automatically switch from the unlocked state to the locked state.

[0066] refer to Figures 5 to 8The locking end 311 of the first hook block 31 has a first limiting protrusion 351 extending toward the second hook block 32 and a limiting groove 353 located on the side of the first limiting protrusion 351 near the rotating part 313. The end of the second hook block 32 near the first hook block 31 has a second limiting protrusion 352 extending toward the first hook block 31. In the locked state, the second limiting protrusion 352 enters the limiting groove 353, and the first limiting protrusion 351 abuts against the second limiting protrusion 352.

[0067] Furthermore, the first limiting protrusion 351 has a first guide surface 3511 on the side away from the limiting groove 353 and a first locking surface 3512 on the side near the limiting groove 353. The second limiting protrusion 352 has a second guide surface 3521 on the side near the first hook block 31 and a second locking surface 3522 on the side away from the first hook block 31. During the movement of the first limiting protrusion 351 into the limiting groove 353, the first guide surface 3511 and the second guide surface 3521 abut against each other, facilitating the second hook block 32 to push the locking end 311 of the first hook block 31 to rotate away from the locking base 33, so that the second limiting protrusion 352 can move into the limiting groove 353. In the locked state, the second limiting protrusion 352 moves into the limiting groove 353, and the first locking surface 3512 abuts against the second locking surface 3522. Preferably, the first guide surface 3511 and the second guide surface 3512 are inclined surfaces or arc-shaped surfaces.

[0068] In actual use, during the process of the stamping fixture 100 switching from the working state to the idle state, the second hook block 32 moves towards the first hook block 31. After the first guide surface 3511 and the second guide surface 3521 come into contact, the second hook block 32 can push the locking end 311 of the first hook block 31 to move away from the locking base 33. After the second hook block 32 continues to move to the position corresponding to the limiting groove 353, the locking end 311 of the first hook block 31 falls back, and the second limiting protrusion 352 of the second hook block 32 moves into the limiting groove 353, and the first hook block 31 and the second hook block 32 are locked together. During the process of switching the stamping fixture 100 from the idle state to the working state, the operating end 32 of the first hook block 31 is operated to drive the locking end 311 to move away from the second hook block 32, so that the first limiting protrusion 351 and the second limiting protrusion 352 are separated, and the second limiting protrusion 352 leaves the limiting groove 353, so that the second hook block 32 can move away from the first hook block 31.

[0069] refer to Figure 5 and Figure 6 The rotating part 313 of the first hook block 31 has a shaft hole 3130; the locking base 33 has a bracket 331 corresponding to the position of the shaft hole 3130. The locking mechanism 30 further includes a shaft pin 36, which passes through the bracket 331 and the shaft hole 3139 to rotatably connect the first hook block 31 and the second hook block 32.

[0070] refer to Figures 5 to 8 The first hook block 31 further includes a connecting rod 37 and a handle ball 38. One end of the connecting rod 37 is mounted on the side of the first hook block 31 whose operating end 312 is away from the locking base 33, and the handle ball 38 is mounted on the end of the connecting rod 37 away from the first hook block 31. When it is necessary to switch the locking mechanism 30 from the locked state to the unlocked state, the operator can hold the handle ball 33 and press the operating end 312 of the first hook block 31 to reduce the distance between the operating end 312 and the locking base 33.

[0071] refer to Figure 5 and Figure 6 The first hook block 31 has a limiting boss 314 extending toward the locking base 33 between the rotating part 313 and the limiting groove 353. The extension length of the limiting boss 314 is greater than the extension length of the first limiting protrusion 352. In the locked state, the limiting boss 313 abuts against the locking base 33 to limit the distance that the first limiting protrusion 351 can move toward the second hook block 32.

[0072] refer to Figure 9The first hook block 31 is slidably mounted on the locking base 33. The locking base 33 has a movable groove 332; the first hook block 31 has a locking end 315 and a sliding end 316, the sliding end 316 being slidably mounted on the movable groove 332. The bottom of the locking end 315 has a third guide surface 3151, and the top of the locking end 315 has a third locking surface 3152; the end of the second hook block 32 has a locking protrusion 317, the upper surface of the locking protrusion 317 has a fourth guide surface 3153, and the lower surface of the locking protrusion 317 has a fourth locking surface 3154. In the locked state, the third locking surface 3152 and the fourth locking surface 3154 abut against each other; in the unlocked state, the locking protrusion 317 is separated from the locking end 315. The locking mechanism 30 further includes an elastic member 34 installed between the sliding end 316 and the bottom wall of the movable groove 332; in the unlocked state, the elastic member 34 has a first state, and in the locked state, the elastic member 34 has a second state, and from the first state to the second state, the elastic member 34 is compressed.

[0073] refer to Figure 2 The stamping fixture 100 further includes a first support member 43, the bottom of the first support member 43 is fixed to the support plate 40, the driving member 20 is installed on the top of the first support member 43, and the driving member 20 and the support plate 40 have a preset angle.

[0074] The stamping fixture 100 further includes at least one slide rail 44, which is mounted on the support plate 40 at a predetermined angle. The slider 10 is disposed above the slide rail 44 and the drive member 20. The bottom of the slider 10 has a sliding part 44. The connecting part of the slider 10 is fixedly connected to the drive rod of the drive member 20, and the sliding part 44 is slidably mounted on the slide rail 44.

[0075] Preferably, there are two slide rails 44, respectively disposed on both sides of the first support member 43. Further, the stamping fixture 100 further includes a second support member 45 disposed between the slide rail 44 and the support plate 40.

In the working state, the limiting rod 46 abuts against the limiting part 13, which can limit the distance the slider 10 moves towards the processing position 41, preventing the product 200 to be processed placed on the processing position 41 from being excessively squeezed. Preferably, there are two limiting rods 46, which are respectively arranged on both sides of the slider 10. Correspondingly, both sides of the slider 10 also have two limiting parts 13 corresponding to the two limiting rods 46.
