Description

Technical Field

[0001] The utility model relates to the technical field of C-shaped steel manufacturing, in particular to a C-shaped steel punching device. Background Technique

[0002] C-shaped steel belongs to a component of steel structure. Its cross-section is similar to the shape of "C". Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. When using C-shaped steel, it is necessary to punch holes in it.

[0003] After retrieval, it is found that a positioning punching device for C-shaped steel processing (publication number: CN218080527U) disclosed in a Chinese patent includes an outer frame. A base is fixedly installed at the bottom of the outer frame, and a processing table is installed at the center of the top of the base; when using this positioning punching device for C-shaped steel processing, first place the C-shaped steel above the processing table, and rotate the adjusting wheel to adjust the distance between the two positioning blocks, so as to facilitate the positioning and fixing of the C-shaped steel; after rotating the adjusting wheel, the pin can be correspondingly inserted into the slot to limit and fix the rotated adjusting wheel, avoiding the rotation of the adjusting wheel during the punching process of C-shaped steel processing. With the restriction of the arc-shaped groove on the positioning block, the movement of the positioning block is also avoided, improving the stability during the processing; finally, start the motor to drive the rotation of the punching head, and then start the electric push rod to make the punching head move down to punch the top of the C-shaped steel.

[0004] However, the above punching device can only punch the top of the C-shaped steel during use and cannot punch the side wall of the C-shaped steel, which has certain limitations. Therefore, improvements are needed. Content of the Utility Model

A pressing plate is fixed at one end of the inserting rod close to the C-shaped steel, and a pushing plate is fixed at the other end of the inserting rod far from the C-shaped steel. An elastic member is arranged between the mounting plate and the pressing plate. The elastic member is a spring, and the spring is sleeved on the inserting rod respectively.

[0010] In order to adjust the distance between two adjacent holes on the side wall of the C-shaped steel, a mechanism for adjusting the distance between two adjacent holes on the side wall of the C-shaped steel is arranged on one side of one of the fixing blocks. The mechanism for adjusting the distance between two adjacent holes on the side wall of the C-shaped steel includes a fixing plate fixed on one side of the fixing block.

[0019] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described.

[0020] As Figure 1 shown, the present utility model provides a C-shaped steel punching device, including a punching mechanism. A base 1 for placing the C-shaped steel M is provided at the feeding end of the punching mechanism.

[0021] As Figure 1 shown, the most important differential design of the present utility model is that two mounting plates 2 are symmetrically arranged on the upper plate surface of the base 1. Four fixing blocks 3 are uniformly fixed on one side of one mounting plate 2. The C-shaped steel M is buckled on the fixing blocks 3, and a structure for fixing the C-shaped steel M is provided on one side of the other mounting plate 2.

[0022] As Figure 4 shown, in order to realize the fixation of the C-shaped steel M, the structure for fixing the C-shaped steel M includes insertion rods 4 uniformly inserted on the side wall of the mounting plate 2. A pressing plate 5 is fixed at one end of the insertion rod 4 close to the C-shaped steel M, and a pushing plate 6 is fixed at the other end of the insertion rod 4 away from the C-shaped steel M. An elastic member is arranged between the mounting plate 2 and the pressing plate 5. The elastic member is a spring 7, and the spring 7 is sleeved on the insertion rod 4 respectively.

[0023] As Figure 2 shown, in order to adjust the distance between two adjacent holes on the side wall of the C-shaped steel M, a mechanism for adjusting the distance between two adjacent holes on the side wall of the C-shaped steel M is provided on one side of one of the fixing blocks 3. The mechanism for adjusting the distance between two adjacent holes on the side wall of the C-shaped steel M includes a fixing plate 8 fixed on one side of the fixing block 3. A limiting rod 9 is inserted on the fixing plate 8. A limiting plate 10 is fixedly sleeved on the outer surface of the limiting rod 9. The limiting plate 10 is a circular plate. A telescopic spring 11 is arranged between the upper plate surface of the fixing plate 8 and the lower plate surface of the limiting plate 10, and the telescopic spring 11 is sleeved on the limiting rod 9.

[0024] As Figure 5 shown, in order to realize the collection of debris, a bearing plate 12 is clamped between two adjacent fixing blocks 3, and one end of the bearing plate 12 penetrates through one of the mounting plates 2. When the punching head on the punching mechanism passes through the C-shaped steel M, some debris will be carried and thus fall onto the bearing plate 12, avoiding the debris from falling between two adjacent fixing blocks 3, which makes it difficult to clean. During the punching operation, the bearing plate 12 can be fixed on the mounting plate 2 with bolts to prevent the bearing plate 12 from moving due to the vibration generated during punching.

[0025] The specific working principle is as follows: When in use, first pull the push plate 6. The push plate 6 drives the insertion rod 4 and the pressing plate 5 to move and compress the spring 7. Then, buckle the M side of the C-shaped steel on the fixed block 3 so that one end of the C-shaped steel M is aligned with the feeding end of the base 1. Subsequently, release the push plate 6, and use the resilience of the spring 7 to push the insertion rod 4 and the pressing plate 5 to move towards the direction where the C-shaped steel M is located until one side of the pressing plate 5 contacts and presses one side of the C-shaped steel M, thereby clamping and fixing the C-shaped steel M on the fixed block 3. Finally, perform a punching operation on the side wall of the C-shaped steel M through the punching mechanism. After the first hole is punched, press down the limit plate 10 to push the limit rod 9 to move downward and compress the telescopic spring 11. Then, pull the C-shaped steel M so that the first hole on the side wall of the C-shaped steel M is aligned with the limit rod 9. Subsequently, release the limit plate 10, and use the resilience of the telescopic spring 11 to push the limit plate 10 and the limit rod 9 to move upward, so that the limit rod 9 is inserted into the hole groove on the side wall of the C-shaped steel M, making the distance between two adjacent holes on the side wall of the C-shaped steel M the same.

[0026] Compared with the prior art, the utility model has the following beneficial effects: By buckling the M side of the C-shaped steel on the fixed block 3, and then using the mutual cooperation of the insertion rod 4, the pressing plate 5 and the push plate 6 to clamp and fix the C-shaped steel M, it is convenient for the punching mechanism to perform a punching operation on the side wall of the C-shaped steel M. Finally, by using the limit rod 9, the limit plate 10 and the telescopic spring 11, the distance between two adjacent holes on the side wall of the C-shaped steel M is the same. The structure is simple and the operation is convenient.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
