Description

Technical Field

[0001] This utility model relates to the field of press technology, and in particular to a shock-absorbing bracket for the cooling fan of the main motor of a press. Background Technology

[0002] The main motor of a press is typically mounted on top of the crossbeam, on a motor support plate, which in turn is mounted on a motor base, which is also mounted on top of the crossbeam. The motor support plate has oblong holes, allowing it to move left and right on the motor base as needed for belt tension. Due to limited space at the top of the crossbeam, the rear cover of the main motor is usually suspended outside the motor support plate. The cooling fan for the main motor is installed within the rear cover, which is connected to the main motor body via multiple plates. During production, especially with progressive dies and multi-station presses, significant machine vibration can occur. Individual connecting plates or joints are prone to breakage, causing the cooling fan to vibrate increasingly strongly until it falls or breaks. In such cases, the main motor cooling fan will trigger an alarm. Without cooling, the main motor's internal temperature will rise, leading to motor damage and machine downtime over time. Utility Model Content

[0003] This utility model addresses the problem of easy breakage in the suspended installation structure of the cooling fan of the main motor of a press in the prior art. It provides a shock-absorbing bracket for the cooling fan of the main motor of a press, which strengthens the connection between the cooling fan and the main structure of the press by adding a shock-absorbing bracket to the cooling fan.

[0004] The objective of this utility model is achieved as follows: a shock-absorbing bracket for a cooling fan of a main motor of a press includes a motor base, a motor support plate on the motor base for mounting the main motor, a cooling fan mounted at the end of the motor, and the cooling fan being supported and mounted inside a fan cover. The characteristic feature is that the open end of the fan cover is circumferentially connected to the end of the motor by several L-shaped connecting plates, and a shock-absorbing bracket is provided between the lower end of the fan cover and the motor base.

[0005] To provide stable support for the cooling fan, the shock-absorbing bracket includes two parallel right-angled bracket plates. The two right-angled ends of the bracket plates are respectively vertically connected to a first connecting plate and a second connecting plate. The first connecting plate is vertically arranged and fixedly connected to the side of the motor base via a transition plate. The second connecting plate is horizontally arranged and is provided with an arc-shaped support for securing the fan cover. The arc-shaped support has a shock-absorbing pad on its arc-shaped surface.

[0006] To facilitate timely adjustment of the shock absorber bracket position to accommodate the adjustment of the main motor position, the connection between the transition plate and the first connecting plate is provided with two rows of waist-shaped mounting holes. The length direction of the waist-shaped mounting holes is consistent with the belt direction of the main motor to accommodate the position adjustment of the shock absorber bracket after the belt tension is adjusted. The waist-shaped mounting holes of the first connecting plate and the transition plate are respectively provided with connecting holes, and the connecting holes and the waist-shaped mounting holes are fixed together by bolts and nuts.

[0007] To further stabilize the shock-absorbing bracket, the lower edge of the transition plate is provided with a limiting step that extends horizontally toward the lower edge of the first connecting plate.

[0008] The beneficial effects of this utility model are as follows: a shock-absorbing bracket fixed to the motor base is set at the lower end of the original fan cover that is suspended at the end of the main motor. This bracket supports the center of gravity of the cooling fan from the suspended lower side, thereby reducing the vibration caused by the cantilever impact during the operation of the cooling fan. This reduces the stress on the connecting plate between the cooling fan cover and the motor side end, avoiding the risk of vibration breakage during long-term operation. At the same time, a shock-absorbing pad is set on the support arc surface of the arc-shaped support base to further reduce the vibration impact caused by rigid contact. Attached Figure Description

[0013] The structure of the shock-absorbing bracket for the cooling fan of the main motor of the press of this utility model is described in detail below with reference to the accompanying drawings.

[0014] like Figure 1 — Figure 3As shown, this utility model presents a shock-absorbing bracket for the cooling fan of the main motor of a press. It includes a motor base 3, which is typically installed on the top of the press's crossbeam, or its installation position can be changed according to actual needs, without affecting the overall structure of the main motor and cooling fan. In this utility model, the motor base 3 has a motor support plate 2 for mounting the main motor 1. The four corners where the motor support plate 2 connects to the motor base 3 have oblong holes 201 for fixing. The length direction of these oblong holes 201 is aligned with the length direction of the belt of the main motor 1. The tension of the belt of the main motor 1 is adjusted by the motor support plate 2 along the length direction of the oblong holes 201. A cooling fan 8 is installed at the end of the main motor 1, supported and installed inside a fan cover 6. The open end of the fan cover 6 is connected to the end of the main motor 1 circumferentially by several L-shaped connecting plates 9. A shock-absorbing bracket 4 connects the lower end of the fan cover 6 to the motor base 3.

[0015] To achieve stable support for the cooling fan, the shock-absorbing bracket 4 of this utility model includes two parallel right-angled bracket plates 402. The two right-angled ends of the bracket plates 402 are respectively vertically connected to a first connecting plate 402 and a second connecting plate 403. The first connecting plate 402 is vertically arranged and fixedly connected to the side of the motor base 3 via a transition plate 5. The transition plate 5 is directly or indirectly fixedly connected to the side of the motor base via a reinforcement. The second connecting plate 403 is horizontally arranged and is provided with an arc-shaped support 404 for supporting the fan cover 6. The arc-shaped surface of the arc-shaped support 404 is provided with a shock-absorbing pad 7 to buffer the vibration during the operation of the fan. In addition, to further strengthen the connection between the fan cover 6 and the shock-absorbing bracket 4, straps can be provided on the outer periphery of the fan cover 6 for further reinforcement.

[0016] To facilitate timely adjustment of the position of the shock absorber bracket 4 to accommodate the adjustment of the main motor position, the connection between the transition plate 5 and the first connecting plate 401 is provided with two rows of waist-shaped mounting holes 502. The length direction of the waist-shaped mounting holes 502 is consistent with the belt direction of the main motor 1 to accommodate the position adjustment of the shock absorber bracket 4 after the belt tension is adjusted. The first connecting plate 401 and the transition plate 5 are respectively provided with connecting holes at corresponding positions of the waist-shaped mounting holes 502. The connecting holes and the waist-shaped mounting holes 502 are fixed together by bolts and nuts.

[0017] To further stabilize the shock absorber bracket 4, the lower edge of the transition plate 5 is provided with a limiting step 502 that extends horizontally towards the lower edge of the first connecting plate 402. The limiting step 502 limits and supports the lower edge of the first connecting plate 402 from the lower side, so as to stabilize the overall connection stability of the shock absorber bracket 4.

[0018] The shock-absorbing bracket for the main motor cooling fan of this utility model, based on the original structure of directly suspending the cooling fan at the end of the main motor, sets up a shock-absorbing bracket 4 fixed to the motor base 3 at the lower end of the fan cover 6. It supports the cooling fan 8 and the fan cover 6 from the lower side of the suspended end in the direction of the center of gravity, so as to reduce the vibration caused by the cantilever impact during the operation of the cooling fan 8, thereby reducing the force on the cooling cover 6 and the L-shaped connecting plate 9 at the side end of the main motor 1, avoiding the risk of vibration and breakage during long-term operation. At the same time, a shock-absorbing pad 7 is set on the support arc surface of the arc support seat 404 to further reduce the vibration impact caused by rigid contact.
