Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stamping equipment, in particular to a pipe stamping device. BACKGROUND

[0002] The lifting column is the core component for realizing the lifting function of the lifting table, and the shell of the lifting column is generally in a tubular structure. In the process of machining the lifting column, the shell of the lifting column needs to be stamped to complete the assembly work of the lifting column. The existing pipe stamping equipment generally comprises a fixing assembly and a stamping assembly. Before the pipe is stamped, the pipe needs to be clamped by the fixing assembly so that the pipe is fixed during the stamping process, and then the stamping assembly is used to stamp the pipe. In the existing scheme, the fixing assembly and the stamping assembly are relatively independently arranged, and each needs a driving member for driving. In the stamping process, the action sequence of the fixing assembly and the stamping assembly needs to be controlled by a control program. The above scheme has a high cost of using two driving members, and the requirement for the driving members is increased by controlling the action sequence of the fixing assembly and the stamping assembly through the control program, which further increases the cost. In addition, when the control program is wrong, the action sequence of the fixing assembly and the stamping assembly is likely to be chaotic. SUMMARY

[0003] In order to overcome the deficiency that the fixing assembly and the stamping assembly of the pipe stamping equipment in the prior art are relatively independently arranged and each needs a driving member for driving, the present application provides a pipe stamping device, which can realize the clamping action and the stamping action of the stamping device by using only one driving member, thereby reducing the number of driving members and reducing the cost.

[0004] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:

[0005] The utility model provides a pipe stamping device, which comprises a fixing frame, a linear driving part, a stamping assembly and a fixing assembly installed on the fixing frame, a guide part connected with the output end of the linear driving part, the fixing assembly comprises two first clamping parts in sliding connection with the fixing frame and symmetrically arranged on both sides of the pipe, the guide part is provided with two first sliding grooves, the first clamping part is provided with a first sliding shaft adapted to the first sliding groove and capable of sliding in the corresponding first sliding groove, the first sliding groove comprises a first positioning long groove and a first driving long groove in communication with each other, the length direction of the first positioning long groove is parallel to the sliding direction of the guide part, so that the first clamping part remains stationary when the first sliding shaft is in the first positioning long groove, the length direction of the first driving long groove forms an angle alpha (0° < alpha < 90°) with the sliding direction of the guide part, so that the first clamping part is driven to approach and clamp the pipe or move away from the pipe by the sliding of the guide part when the first sliding shaft is in the first driving long groove, the stamping assembly comprises a stamping part in sliding connection with the fixing frame, and the stamping part is in transmission connection with the guide part, so that the stamping part is driven to slide and stamp the pipe by the sliding of the guide part.

[0006] In the technical solution, one linear driving member drives one guide member to slide, and the guide member simultaneously drives the stamping member and the clamping member to move, so that the clamping action and the stamping action of the stamping device can be realized by using only one driving member, compared with the scheme in which the stamping action and the clamping action are realized by two driving members, the number of driving members can be reduced, and the cost is reduced, and the timing of the actions of the stamping member and the clamping member can be ensured to be stable at all times, and the situation that the timing of the clamping action and the stamping action is chaotic due to an error of a control system does not occur. The length direction of the first positioning long groove is parallel to the sliding direction of the guide member, when the first sliding shaft is in the first positioning long groove, only the guide member slides in the sliding process of the guide member, and the first sliding shaft cannot slide, so that the first clamping member can be kept stationary relative to the fixed frame, the length direction of the first driving long groove has an angle alpha with the sliding direction of the guide member, when the first sliding shaft is in the first driving long groove, the first sliding shaft slides relative to the fixed frame in the sliding process of the guide member, so as to drive the first clamping member to move close to or away from the pipe. After the first positioning long groove and the first driving long groove are connected, in the process of stamping the pipe, the guide member moves forward, the first sliding shaft is first in the first driving long groove and slides along the first driving long groove, the first sliding shaft slides at the same time to drive the first clamping member to move in the direction close to the pipe, when the first clamping member clamps the pipe, the first sliding shaft enters the first positioning long groove, at this time, the sliding of the guide member will not continue to drive the first clamping member to move, but keep the position of the first clamping member clamping the pipe unchanged, and the continuous sliding of the guide member can drive the stamping member to stamp the pipe. In the process of withdrawing after stamping is completed, the guide member moves reversely, the first sliding shaft is first in the first positioning long groove and slides along the first positioning long groove, the sliding of the guide member will not drive the first clamping member to move, but keep the position of the first clamping member clamping the pipe unchanged, at this time, the sliding of the guide member drives the stamping member to move away from the pipe, so that the stamping member withdraws from the stamping position, after the first sliding shaft enters the first driving long groove, the sliding of the guide member can drive the first clamping member and the stamping member to move away from the pipe, so as to facilitate the pipe to be taken out. The above technical solution makes the two first clamping members clamp the pipe symmetrically from both sides of the pipe, and the clamping effect is more stable.

[0007] As preferred, the fixing assembly further comprises a second clamping member and a first sliding member respectively in sliding connection with the fixing frame, the fixing assembly further comprises the first sliding member in sliding connection with the fixing frame, the guide member is provided with a second sliding groove, the first sliding member is provided with a second sliding shaft which is adapted to the second sliding groove and can slide in the second sliding groove, so as to drive the first sliding member to slide through the sliding of the guide member, the first sliding member is provided with a third sliding groove, the second clamping member is provided with a third sliding shaft which is adapted to the third sliding groove and can slide in the third sliding groove, the third sliding groove comprises a third positioning long groove and a third driving long groove which are in communication with each other, the length direction of the third positioning long groove is parallel to the sliding direction of the first sliding member, so as to keep the second clamping member static when the third sliding shaft is in the third positioning long groove, the length direction of the third driving long groove has an angle β with the sliding direction of the first sliding member, 0°<β<90°, so as to drive the second clamping member to approach or move away from the pipe member through the sliding of the first sliding member when the third sliding shaft is in the third driving long groove, the angle between the sliding direction of the at least one second clamping member and the sliding direction of the guide member is greater than 90°.

[0008] In the technical scheme, the number of the second clamping members and the first sliding members is at least one, and the first sliding members correspond to the second clamping members one by one. The sliding of the guide member can drive the first sliding member to slide. Since the length direction of the third positioning long slot is parallel to the sliding direction of the first sliding member, the third sliding shaft cannot slide in the process of the sliding of the first sliding member when the third sliding shaft is in the third positioning long slot, so that the second clamping member can be kept stationary. Since the length direction of the third driving long slot has an angle β with the sliding direction of the first sliding member, the third sliding shaft can slide relative to the fixed frame in the process of the sliding of the first sliding member when the third sliding shaft is in the third driving long slot, so as to drive the second clamping member to move close to or away from the pipe. In the process of stamping the pipe, the guide member moves forward, the sliding of the guide member can always drive the first sliding member to slide, the third sliding shaft is first in the third driving long slot and slides along the third driving long slot, the third sliding shaft drives the second clamping member to move in the direction close to the pipe while sliding, the second clamping member clamps the pipe, and the third sliding shaft enters the third positioning long slot at this moment, so that the sliding of the first sliding member cannot continue to drive the second clamping member to move, but keeps the position of the second clamping member clamping the pipe unchanged, and the guide member continues to slide to drive the stamping member to stamp the pipe. In the process of exiting after stamping is completed, the guide member moves reversely, the first sliding member always slides reversely, the third sliding shaft is first in the third positioning long slot and slides along the third positioning long slot, the sliding of the first sliding member cannot drive the second clamping member to move, but keeps the position of the second clamping member clamping the pipe unchanged, the first sliding member slides to drive the stamping member to move away from the pipe at this moment, the stamping member exits the stamping position, and the third sliding shaft enters the third driving long slot, so that the sliding of the first sliding member can drive the second clamping member and the stamping member to move away from the pipe, facilitating the pipe to be taken out. The above technical scheme can set the sliding direction of the second clamping member to be greater than 90° with the sliding direction of the guide member by setting the first sliding member between the guide member and the second clamping member, so as to clamp the pipe from various angles, the fixation is more reliable, and the pipe can be suspended and fixed relative to the fixed frame by the fixing assembly, facilitating the stamping assembly to stamp various positions of the suspended and fixed pipe in the subsequent stamping process.

During the withdrawal after the punching is completed, the guide member moves reversely and drives the punching member to move away from the pipe.

[0031] In the above technical solution, as shown in Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the length direction of the first positioning long slot 3.1.1 is parallel to the sliding direction of the guide 3, when the first sliding shaft 4.2 is in the first positioning long slot 3.1.1, only the guide 3 slides during the sliding process of the guide 3, and the first sliding shaft 4.2 cannot slide, so that the first clamping piece 4.1.1 can be kept stationary relative to the fixed frame 1, the length direction of the first driving long slot 3.1.2 has an angle α with the sliding direction of the guide 3, when the first sliding shaft 4.2 is in the first driving long slot 3.1.2, the first sliding shaft 4.2 will slide relative to the fixed frame 1 during the sliding process of the guide 3, so as to drive the first clamping piece 4.1.1 to approach or move away from the pipe 6. After the first positioning long slot 3.1.1 and the first driving long slot 3.1.2 are connected, during the stamping process of the pipe 6, the guide 3 moves forward, the first sliding shaft 4.2 is first in the first driving long slot 3.1.2 and slides along the first driving long slot 3.1.2, the first sliding shaft 4.2 slides at the same time and drives the first clamping piece 4.1.1 to move in the direction of approaching the pipe 6, when the first clamping piece 4.1.1 clamps the pipe 6, the first sliding shaft 4.2 just enters the first positioning long slot 3.1.1, at this time the sliding of the guide 3 will not continue to drive the first clamping piece 4.1.1 to move, but keep the position of the first clamping piece 4.1.1 clamping the pipe 6 unchanged, the continuous sliding of the guide 3 can drive the stamping piece 5.1 to stamp the pipe 6. During the process of withdrawing after stamping is completed, the guide 3 moves reversely, the first sliding shaft 4.2 is first in the first positioning long slot 3.1.1 and slides along the first positioning long slot 3.1.1, the sliding of the guide 3 will not drive the first clamping piece 4.1.1 to move, but keep the position of the first clamping piece 4.1.1 clamping the pipe 6 unchanged, at this time the sliding of the guide 3 drives the stamping piece 5.1 to move away from the pipe 6, so that the stamping piece 5.1 withdraws from the stamping position, after the first sliding shaft 4.2 enters the first driving long slot 3.1.2, the sliding of the guide 3 can drive the first clamping piece 4.1.1 and the stamping piece 5.1 to move away from the pipe 6, which is convenient for taking out the pipe 6.

The upper end of the first driving long slot 3.1.2 is inclined to the pipe 6. The forward direction of the guide 3 is the vertical downward direction, and the reverse direction of the guide 3 is the vertical upward direction.

[0034] Preferably, the included angle a is 30°, 35°, 40°, 45°, 50°, 55°, 60°. The size of the included angle a can be set according to actual needs. In the case of the same distance of the guide member, the closer the included angle is to 90°, the greater the moving distance of the first clamping member is, and the closer the included angle is to 0°, the smaller the moving distance of the first clamping member is. It can be understood that the included angle a can also be other suitable directions within the range.

[0035] Preferably, the number of the first clamping member 4.1.1, the first sliding groove 3.1 and the first sliding shaft 4.2 is two, and they are one-to-one correspondingly arranged. The two first clamping members 4.1.1 are symmetrically arranged on both sides of the pipe fitting 6. The above technical solution makes the two first clamping members 4.1.1 symmetrically clamp the pipe fitting 6 from both sides of the pipe fitting 6, and the clamping effect is more stable.

[0036] Preferably, as shown in Figure 4 and Figure 5 , the clamping member 4.1 further comprises a second clamping member 4.1.2, and the fixing assembly 4 further comprises a first sliding member 4.3 in sliding connection with the fixing frame 1. The guide member 3 is provided with a second sliding groove 3.2. The first sliding member 4.3 is provided with a second sliding shaft 4.4 which is adapted to the second sliding groove 3.2 and can slide in the second sliding groove 3.2, so as to drive the first sliding member 4.3 to slide through the sliding of the guide member 3. The first sliding member 4.3 is provided with a third sliding groove 4.5. The second clamping member 4.1.2 is provided with a third sliding shaft 4.6 which is adapted to the third sliding groove 4.5 and can slide in the third sliding groove 4.5.

The length direction of the third positioning long groove 4.5.1 is parallel to the sliding direction of the first sliding member 4.3, so that the second clamping member 4.1.2 remains stationary when the third sliding shaft 4.6 is in the third positioning long groove 4.5.1. The length direction of the third driving long groove 4.5.2 has an included angle β with the sliding direction of the first sliding member 4.3, 0°<β<90°, so that the second clamping member 4.1.2 is driven to approach or move away from the pipe fitting 6 through the sliding of the first sliding member 4.3 when the third sliding shaft 4.6 is in the third driving long groove 4.5.2. The included angle between the sliding direction of at least one second clamping member 4.1.2 and the sliding direction of the guide member 3 is greater than 90°.

The sliding of the guide 3 can drive the first sliding member 4.3 to slide. Since the length direction of the third positioning long slot 4.5.1 is parallel to the sliding direction of the first sliding member 4.3, when the third sliding shaft 4.6 is in the third positioning long slot 4.5.1, the first sliding member 4.3 cannot drive the third sliding shaft 4.6 to slide during the sliding process, so that the second clamping member 4.1.2 can remain stationary. Since the length direction of the third driving long slot 4.5.2 and the sliding direction of the first sliding member 4.3 form an angle β, when the third sliding member sliding shaft is in the third driving long slot 4.5.2, the third sliding shaft 4.6 will slide relative to the fixed frame 1 during the sliding process of the first sliding member 4.3, thereby driving the second clamping member 4.1.2 to move closer to or away from the pipe 6. During the stamping process of the pipe 6, the guide 3 moves forward, the sliding of the guide 3 can always drive the first sliding member 4.3 to slide, the third sliding shaft 4.6 first enters the third driving long slot 4.5.2 and slides along the third driving long slot 4.5.2, the third sliding shaft 4.6 slides while driving the second clamping member 4.1.2 to move towards the pipe 6, when the second clamping member 4.1.2 clamps the pipe 6, the third sliding shaft 4.6 just enters the third positioning long slot 4.5.1, at this time, the sliding of the first sliding member 4.3 will not continue to drive the second clamping member 4.1.2 to move, but keep the position of the second clamping member 4.1.2 clamping the pipe 6 unchanged, the guide 3 continues to slide to drive the stamping member 5.1 to stamp the pipe 6. After stamping is completed, the guide 3 moves reversely, the first sliding member 4.3 always slides reversely, the third sliding shaft 4.6 first enters the third positioning long slot 4.5.1 and slides along the third positioning long slot 4.5.1, the sliding of the first sliding member 4.3 will not drive the second clamping member 4.1.2 to move, but keep the position of the second clamping member 4.1.2 clamping the pipe 6 unchanged, at this time, the sliding of the first sliding member 4.3 drives the stamping member 5.1 to move away from the pipe 6, so that the stamping member 5.1 exits the stamping position, after the third sliding shaft 4.6 enters the third driving long slot 4.5.2, the sliding of the first sliding member 4.3 can drive the second clamping member 4.1.2 and the stamping member 5.1 to move away from the pipe 6, which is convenient for taking out the pipe 6.The technical scheme sets the sliding direction of the second clamping piece 4.1.2 to be greater than 90° with the sliding direction of the guide piece 3, so that the pipe 6 can be clamped from various angles, the fixing is more reliable, and the pipe 6 can be suspendedly fixed relative to the fixing frame 1 by the fixing assembly 4, so that the punching assembly 5 can punch various positions of the suspendedly fixed pipe 6 in the subsequent punching process.

[0038] Preferably, the included angle β is 30°, 35°, 40°, 45°, 50°, 55°, or 60°. The size of the included angle β can be set according to actual needs. In the case that the first sliding piece moves the same distance, the greater the included angle is close to 90°, the greater the moving distance of the second clamping piece is, and the closer the included angle is to 0°, the smaller the moving distance of the second clamping piece is. It can be understood that the included angle α can also be other suitable directions in the range.

[0039] Preferably, the sliding direction of the first sliding piece 4.3 is perpendicular to the sliding direction of the guide piece 3, and the sliding direction of the second clamping piece 4.1.2 is the same as or opposite to the sliding direction of the guide piece 3.
