Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a material pushing device for a forming punch press. Background Technology

[0002] Existing products include a pusher guide rail device, which uses two left and right guide rail positioning plates to position and fix the guide rail; and a feeding device, which utilizes the sliding of guide wheels during the reciprocating motion of the upper template to drive the pusher seat, causing the feeding slider to reciprocate and achieve the principle of automatic feeding. The main drawback of the existing technology is:

[0003] 1. The pusher guide rail device uses two guide rail positioning plates on the left and right to position and fix the guide rail. However, the matching accuracy requirements during the sliding process are high, and the parallelism and perpendicularity requirements of the two guide rail positioning plates are also high. There is a risk of jamming during the locking process, and the frictional resistance is large. 2. The original feeding device uses the upper template to drive the pusher seat to move back and forth during the reciprocating motion of the guide wheel, so as to achieve the principle of automatic feeding. However, the length of the upper template punch and the core rod will affect the upper and lower working stroke of the template, which will affect the reciprocating movement distance of the pusher seat, thus affecting the movement distance of the feeding slider, thereby affecting the risk of incomplete product feeding.

[0029] Design concept: Design a dedicated feeding device for a forming punch press. By using a slider device, the friction and fitting accuracy of the guide rail sliding process are reduced, making the feeding process smooth. By improving the feeding process, the risk of incomplete feeding caused by the length of the die punch and mandrel in the original device is avoided. At the same time, the production and die debugging time is reduced, and the efficiency is improved.

[0030] Example:

[0031] like Figures 1-5 As shown, the technical solution of this product is: a forming punch press pushing device, including a horizontal table plate 1, and further including a pushing device 2, a feeding device 3 and a clamping device 4 installed on the horizontal table plate 1. The front end of the pushing device 2 is provided with a clamping device 4, the opening of the clamping device 4 is provided with a mold cavity 5, and the feeding device 3 is provided on the feeding side of the clamping device 4.

[0032] The feeding device 2 in this embodiment includes a machine cam 21, a slider connecting rod 22, a slider guide rail 23, and a feeding slider 24. The machine cam 21 rotates and drives the feeding slider 24 to slide along the slider guide rail 23 to push the material through the slider connecting rod 22. It further includes a clamping arm 25, slider balls 26, and a first return spring 27. The feeding slider 24 is fixedly installed to the clamping device 4 through the clamping arm 25. Two rows of linearly arranged slider balls 26 are provided at the contact point between the inner side of the feeding slider 24 and the slider guide rail 23, which can reduce the friction force during the movement of the slider guide rail 23 and reduce the resistance. A first return spring 27 is provided between the slider guide rail 23 and the feeding slider 24.

[0033] The feeding device 3 in this embodiment includes a guide seat 31, a traction wire 32, a push rod 33, and a feeding slider 34. The push rod 33 is rotatably connected to the guide seat 31. One end of the push rod 33 is connected to the traction wire 32, and the other end is in contact with the feeding slider 34. The feeding slider 34 is slidably connected to the guide seat 31, and the sliding direction is directly opposite to the clamping device 4. It further includes a second return spring 35, and a second return spring 35 is provided between the feeding slider 34 and the guide seat 31.

[0034] The clamping device 4 in this embodiment includes a fixed clamp 41, a movable clamp 42 and a third return spring 43. The third return spring 43 is provided between the fixed clamp 41 and the movable clamp 42. The clamping device 4 also includes a mold cavity 5.

[0035] Working principle:

[0036] The machine tool cam 21 of this product 6 (shaft sleeve) rotates and pushes the slider connecting rod 22 to rise and fall. The slider connecting rod 22 further drives the pusher slider 24 to move linearly along the slider guide rail 23, thereby driving the clamping device 4 at the front end to complete the pusher action. At the starting position, the traction wire 32 drives the push rod 33 to rotate, thereby pushing the feed slider 34 forward to push the product into the mold cavity 5 of the clamping device 4 to complete the product pusher action. After the product is processed, the clamping device 4 opens, and finally each return spring completes the reset and return action of each component.
