Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically a bending machine protective device. Background Technology

[0002] If a worker's hand accidentally gets caught in a bending machine while it is bending, it can have extremely serious consequences. Such accidents are common. Bending machine protection is crucial for ensuring the safety of operators, the normal operation of equipment, and improving production efficiency. Therefore, it is necessary to design a bending machine protection device to prevent such incidents from occurring. Utility Model Content

[0003] The purpose of this utility model is to provide a protective device for bending machines to solve the problem of bending machines easily crushing hands, as mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bending machine protective device, including a bending machine upper blade, a fixed crossbeam fixedly installed on the front of the bending machine upper blade, multiple mounting holes opened on the fixed crossbeam, a telescopic sleeve fixedly installed above the fixed crossbeam, the telescopic sleeve including an outer sleeve and an inner sleeve, the outer sleeve fixedly installed on the fixed crossbeam, the inner sleeve slidably inserted into the outer sleeve and provided with a sliding limit, the inner sleeve passing through the mounting hole and fitted with a spring, a baffle plate provided in front of the bending machine upper blade, the top of the baffle plate being fixed to the inner sleeve.

[0005] Preferably, the crossbeam is T-shaped and is fixedly connected to the front of the blade on the bending machine by screws. Both ends of the crossbeam are flush with the sides of the blade on the bending machine.

[0006] Preferably, the baffle is a transparent acrylic sheet, the length of the baffle is the same as the length of the fixed crossbeam and both ends are flush, and the bottom of the baffle is rounded.

[0007] Preferably, when the spring is in its natural state, the bottom of the baffle is lower than the bottom of the blade on the bending machine.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] This utility model discloses a protective device for a bending machine. The bending machine blade is designed to fall in two stages. During the first stage of falling, a baffle installed in front of the blade on the bending machine can fall before the blade. When the worker's hand is placed under it, the second stage of falling is stopped. When there are no foreign objects under it, the second stage of falling is started. During the second stage of falling, the baffle prevents the hand from entering the bending machine, thus providing protection. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 A bending machine protective device includes a bending machine upper blade 1, a fixed crossbeam 2 fixedly installed on the front of the bending machine upper blade 1, a plurality of mounting holes 6 opened on the fixed crossbeam 2, a telescopic sleeve 5 fixedly installed above the fixed crossbeam 2, the telescopic sleeve 5 includes an outer sleeve and an inner sleeve, the outer sleeve is fixedly installed on the fixed crossbeam 2, the inner sleeve is slidably inserted into the outer sleeve and is provided with a sliding limit, the inner sleeve passes through the mounting holes 6 and is fitted with a spring 4, a baffle 3 is provided in front of the bending machine upper blade 1, and the top of the baffle 3 is fixed to the inner sleeve.

[0016] Specifically, the crossbeam 2 is T-shaped and is fixedly connected to the front of the blade 1 on the bending machine by screws. The two ends of the crossbeam 2 are flush with the two sides of the blade 1 on the bending machine.

[0017] The baffle 3 is made of transparent acrylic sheet. The length of the baffle 3 is the same as the length of the fixed crossbeam 2 and both ends are flush. The bottom of the baffle 3 is rounded to prevent the bent and folded sheet material from being scratched by the bottom of the baffle 3. When the spring 4 is in its natural state, the bottom of the baffle 3 is lower than the bottom of the blade 1 on the bending machine.

[0018] Working Principle: This utility model discloses a protective device for a bending machine. When the sheet metal is placed inside the bending machine for bending, the baffle 3 moves downwards along with the upper blade 1 and presses down on the sheet metal. At this point, the upper blade 1 completes its first stage of movement and stops. A safe distance remains between the upper blade 1 and the sheet metal. If a worker's hand or other object is not removed from the danger zone, the baffle 3 will press down on the hand or object. However, the top of the baffle 3 is elastically connected and will not apply excessive pressure. Therefore, the hand or other object must be promptly removed from under the upper blade 1 to prevent accidents. When the hand is removed from under the baffle 3, the second stage of the upper blade 1's stroke begins. If a hand is then inserted into the bending machine, it will be blocked by the baffle 3. Furthermore, during the bending process, the baffle 3 remains in contact with the sheet metal, preventing particles from splashing during bending and providing protection.
